TITLE A. GENERAL CONDITIONS.

Topic I. OF SENSE-PERCEPTION.

Section 35.

Our conclusions depend upon perceptions made by ourselves and others. And if the perceptions are good our judgments may be good, if they are bad our judgments must be bad. Hence, to study the forms of sense-perception is to study the fundamental conditions of the administration of law, and the greater the attention thereto, the more certain is the administration.

It is not our intention to develop a theory of perception. We have only to extract those conditions which concern important circumstances, criminologically considered, and from which we may see how we and those we examine, perceive matters. A thorough and comprehensive study of this question can not be too much recommended. Recent science has made much progress in this direction, and has discovered much of great importance for us. To ignore this is to confine oneself merely to the superficial and external, and hence to the inconceivable and incomprehensible, to ignoring valuable material for superficial reasons, and what is worse, to identifying material as important which properly understood has no value whatever.

Section 36. (a) General Considerations.

The criminalist studies the physiological psychology[1] of the senses and their functions, in order to ascertain their nature, their influence upon images and concepts, their trustworthiness, their reliability and its conditions, and the relation of perception to the object. The question applies equally to the judge, the jury, the witness, and the accused. Once the essence of the function and relation of sense-perception is understood, its application in individual cases becomes easy.

The importance of sense-perception need not be demonstrated. "If we ask," says Mittermaier, "for the reason of our conviction of the truth of facts even in very important matters, and the basis of every judgment concerning existence of facts, we find that the evidence of the senses is final and seems, therefore, the only true source of certainty."

There has always, of course, been a quarrel as to the objectivity and reliability of sense-perception. That the senses do not lie, "not because they are always correct, but because they do not judge," is a frequently quoted sentence of Kant's; the Cyrenaics have already suggested this in asserting that pleasure and pain alone are indubitable. Aristotle narrows the veracity of sensation to its essential content, as does Epicurus. Descartes, Locke and Leibnitz have suggested that no image may be called, as mere change of feeling, true or false. Sensationalism in the work of Gassendi, Condillac, and Helvetius undertook for this reason the defense of the senses against the reproach of deceit, and as a rule did it by invoking the infallibility of the sense of touch against the reproach of the contradictions in the other senses. Reid went back to Aristotle in distinguishing specific objects for each sense and in assuming the truth of each sense within its own field.

That these various theories can be adjusted is doubtful, even if, from a more conservative point of view, the subject may be treated quantitatively. The modern quantification of psychology was begun by Herbart, who developed a mathematical system of psychology by introducing certain completely unempirical postulates concerning the nature of representation and by applying certain simple premises in all deductions concerning numerical extent. Then came Fechner, who assumed the summation of stimuli. And finally these views were determined and fixed by the much-discussed Weber's Law, according to which the intensity of the stimulus must increase in the proportion that the intensity of the sensation is to increase; i. e., if a stimulus of 20 units requires the addition of 3 before it can be perceived, a stimulus of 60 units would require the addition of 9. This law, which is of immense importance to criminalists who are discussing the sense-perceptions of witnesses, has been thoroughly and conclusively dealt with by A. Meinong.[2]

"Modern psychology takes qualities perceived externally to be in themselves subjective but capable of receiving objectivity through

our relation to the outer world.... The qualitative character of our sensory content produced by external stimuli depends primarily on the organization of our senses. This is the fundamental law of perception, of modern psychology, variously expressed, but axiomatic in all physiological psychology."[3] In this direction Helmholtz[4] has done pioneer work. He treats particularly the problem of optics, and physiological optics is the study of perception by means of the sense of sight. We see things in the external world through the medium of light which they direct upon our eyes. The light strikes the retina, and causes a sensation. The sensation brought to the brain by means of the optic nerve becomes the condition of the representation in consciousness of certain objects distributed in space.... We make use of the sensation which the light stimulates in the mechanism of the optic nerve to construct representations concerning the existence, form, and condition of external objects. Hence we call images perceptions of sight. (Our sense-perception, according to this theory, consists, therefore, entirely of sensations; the latter constitute the stuff or the content from which the other is constructed). Our sensations are effects caused in our organs, externally, and the manifestation of such an effect depends essentially upon the nature of the apparatus which has been stimulated.

There are certain really known inferences, e. g., those made by the astronomer from the perspective pictures of the stars to their positions in space. These inferences are founded upon well-studied knowledge of the principles of optics. Such knowledge of optics is lacking in the ordinary function of seeing; nevertheless it is permissible to conceive the psychical function of ordinary perception as unconscious inferences, inasmuch as this name will completely distinguish them from the commonly so-called conscious inferences.

The last-named condition is of especial importance to us. We need investigation to determine the laws of the influence of optical and acoustical knowledge upon perception. That these laws are influential may be verified easily. Whoever is ignorant, e. g., that a noise is reflected back considerably, will say that a wagon is turning from the side from which the noise comes, though if he knows the law, if he knows that fact, his answer would be reversed. So, as every child knows that the reflection of sound is frequently deceptive, everybody who is asked in court will say that he believes the wagon

to be on the right side though it might as well have been on the left. Again, if we were unaware that light is otherwise refracted in water than in air we could say that a stick in the water has been bent obtusely, but inasmuch as everybody knows this fact of the relation of light to water, he will declare that the stick appears bent but really is straight.

From these simplest of sense-perceptions to the most complicated, known only to half a dozen foremost physicists, there is an infinite series of laws controlling each stage of perception, and for each stage there is a group of men who know just so much and no more. We have, therefore, to assume that their perceptions will vary with the number and manner of their accomplishments, and we may almost convince ourselves that each examinee who has to give evidence concerning his sense-perception should literally undergo examination to make clear his scholarly status and thereby the value of his testimony. Of course, in practice this is not required. First of all we judge approximately a man's nature and nurture and according to the impression he makes upon us, thence, his intellectual status. This causes great mistakes. But, on the other hand, the testimony is concerned almost always with one or several physical events, so that a simple relational interrogation will establish certainly whether the witness knows and attends to the physical law in question or not. But anyway, too little is done to determine the means a man uses to reach a certain perception. If instantaneous contradictions appear, there is little damage, for in the absence of anything certain, further inferences are fortunately made in rare cases only. But when the observation is that of one person alone, or even when more testify but have accidentally the same amount of knowledge and hence have made the same mistake, and no contradiction appears, we suppose ourselves to possess the precise truth, confirmed by several witnesses, and we argue merrily on the basis of it. In the meantime we quite forget that contradictions are our salvation from the trusting acceptance of untruth— and that the absence of contradiction means, as a rule, the absence of a starting point for further examination.

For this reason and others modern psychology requires us to be cautious. Among the others is the circumstance that perceptions are rarely pure. Their purity consists in containing nothing else than perception; they are mixed when they are connected with imaginations, judgments, efforts, and volitions. How rarely a perception is pure I have already tried to show; judgments almost

always accompany it. I repeat too, that owing to this circumstance and our ignorance of it, countless testimonies are interpreted altogether falsely. This is true in many other fields. When, for example, A. Fick says: "The condition we call sensation occurs in the consciousness of the subject when his sensory nerves are stimulated," he does not mean that the nervous stimulus in itself is capable of causing the condition in question. This one stimulus is only a single tone in the murmur of countless stimuli, which earlier and at the same time have influenced us and are different in their effect on each man. Therefore, that single additional tone will also be different in each man. Or, when Bernstein says that "Sensation, i. e., the stimulation of the sensorium and the passage of this stimulation to the brain, does not in itself imply the perception of an object or an event in the external world," we gather that the objectivity of the perception works correctively not more than one time out of many. So here again everything depends upon the nature and nurture of the subject.

Sensations are, according to Aubert, still more subjective. "They are the specific activity of the sense organs, (not, therefore, passive as according to Helmholtz, but active functions of the sense organs). Perception arises when we combine our particular sensations with the pure images of the spirit or the schemata of the understanding, especially with the pure image of space. The so-called ejection or externalization of sensations occurs only as their scheme and relation to the unity of their object."

So long as anything is conceived as passive it may always recur more identically than when it is conceived as active. In the latter case the individuality of the particular person makes the perception in a still greater degree individual, and makes it almost the creature of him who perceives. Whether Aubert is right or not is not our task to discover, but if he is right then sense-perception is as various as is humanity. The variety is still further increased by means of the comprehensive activity which Fischer[5] presupposes. "Visual perception has a comprehensive or compounding activity. We never see any absolute simple and hence do not perceive the elements of things. We see merely a spatial continuum, and that is possible only through comprehensive activity—especially in the case of movement in which the object of movement and the environment must both be perceived." But each individual method of "comprehension" is different. And it is uncertain whether this

is purely physical, whether only the memory assists (so that the attention in biased by what has been last perceived), whether imagination is at work or an especial psychical activity must be presupposed in compounding the larger elements. The fact is that men may perceived an enormous variety of things with a single glance. And generally the perceptive power will vary with the skill of the individual. The narrowest, smallest, most particularizing glance is that of the most foolish; and the broadest, most comprehensive, and comparing glance, that of the most wise. This is particularly noticeable when the time of observation is short. The one has perceived little and generally the least important; the other has in the same time seen everything from top to bottom and has distinguished between the important and the unimportant, has observed the former rather longer than the latter, and is able to give a better description of what he has seen. And then, when two so different descriptions come before us, we wonder at them and say that one of them is untrue.[6]

The speed of apperception has been subjected to measurement by Auerbach, Kries, Baxt, von Tigerstedt and Bergqvist, Stern, Vaschide, Vurpass, etc. The results show 0.015 to 0.035 seconds for compounded images. Unfortunately, most of these experiments have brought little unanimity in the results and have not compared, e. g., the apperception-times of very clever people with those of very slow and stupid ones. In the variety of perception lies the power of presentation (in our sense of the term). In the main other forces assist in this, but when we consider how the senses work in combination we must conclude that they determine their own forms. "If we are to say that sense experience instructs us concerning the manifoldness of objects we may do so correctly if we add the scholium that many things could not be mentioned without synthesis." So Dörner writes. But if we approach the matter from another side, we see how remarkable it is that human perceptions can be compared at all. Hermann Schwarz says "According to the opinion of the physicists we know external events directly by means of the organs, the nerves of which serve passively to support consciousness in the perception of such events. On the contrary, according to the opinion of most physiologists, the nerve fibers are active in the apprehension of external events, they modify it, alter it until it is well nigh unrecognizable, and turn it over to consciousness only after the original process has undergone still another transformation

into new forms of mechanical energy in the ganglion cells of the outer brain. This is the difference between the physical theory of perception and the physiological."

In this connection there are several more conditions pertaining to general sense-perception. First of all there is that so-called vicariousness of the senses which substitutes one sense for another, in representation. The actual substitution of one sense by another as that of touch and sight, does not belong to the present discussion. The substitution of sound and sight is only apparent. E. g., when I have several times heard the half-noticed voice of some person without seeing him, I will imagine a definite face and appearance which are pure imagination. So again, if I hear cries for help near some stream, I see more or less clearly the form of a drowning person, etc. It is quite different in touching and seeing; if I touch a ball, a die, a cat, a cloth, etc., with my eyes closed, then I may so clearly see the color of the object before me that I might be really seeing it. But in this case there is a real substitution of greater or lesser degree.

The same vicariousness occurs when perception is attributed to one sense while it properly belongs to another. This happens particularly at such times when one has not been present during the event or when the perception was made while only half awake, or a long time ago, and finally, when a group of other impressions have accompanied the event, so that there was not time enough, if I may say so, properly to register the sense impression. So, e. g., some person, especially a close friend, may have been merely heard and later quite convincingly supposed to have been seen. Sensitive people, who generally have an acuter olfactory sense than others, attach to any perceived odor all the other appropriate phenomena. The vicariousnesses of visual sensations are the most numerous and the most important. Anybody who has been pushed or beaten, and has felt the blows, will, if other circumstances permit and the impulse is strong enough, be convinced that he has seen his assaulter and the manner of the assault. Sometimes people who are shot at will claim to have seen the flight of the ball. And so again they will have seen in a dark night a comparatively distant wagon, although they have only heard the noise it made and felt the vibration. It is fortunate that, as a rule, such people try to be just in answering to questions which concern this substitution of one sense-perception for another. And such questions ought to be urgently put. That a false testimony can cause significant errors is as obvious as the fact

that such substitutions are most frequent with nervous and imaginative persons.

Still more significant is that characteristic phenomenon, to us of considerable importance, which might be called retrospective illumination of perception. It consists in the appearance of a sense-perception under conditions of some noticeable interruption, when the stimulus does not, as a rule, give rise to that perception. I cite a simple example in which I first observed this fact. Since I was a child there had been in my bed-room a clock, the loud ticking of which habit of many years prevented my hearing. Once, as I lay awake in bed, I heard it tick suddenly three times, then fall silent and stop. The occurrence interested me, I quickly got a light and examined the clock closely. The pendulum still swung, but without a sound; the time was right. I inferred that the clock must have stopped going just a few minutes before. And I soon found out why: the clock is not encased and the weight of the pendulum hangs free. Now under the clock there always stood a chair which this time had been so placed as to be inclined further backward. The weight followed that inclination and so the silence came about.

I immediately made an experiment. I set the clock going again, and again held the weight back. The last beats of the pendulum were neither quicker nor slower, nor louder or softer than any others, before the sudden stoppage of the clock. I believe the explanation to be as follows: As customary noises especially are unheard, I did not hear the pendulum of the clock. But its sudden stopping disturbed the balance of sound which had been dominating the room. This called attention to the cause of the disturbance, i. e., the ticking which had ceased, and hence perception was intensified backwards and I heard the last ticks, which I had not perceived before, one after another. The latent stimulus caused by the ticking worked backward. My attention was naturally awakened only after the last tick, but my perception was consecutive.

I soon heard of another case, this time, in court. There was a shooting in some house and an old peasant woman, who was busy sewing in the room, asserted that she had just before the shooting heard a few steps in the direction from which the shot must have come. Nobody would agree that there was any reason for supposing that the person in question should have made his final steps more noisily than his preceding ones. But I am convinced that the witness told the truth. The steps of the new arrival were perceived subconsciously; the further disturbance of the perception hindered

her occupation and finally, when she was frightened by the shot, the upper levels of consciousness were illuminated and the noises which had already reached the subconsciousness passed over the threshold and were consciously perceived.

I learned from an especially significant case, how the same thing could happen with regard to vision. A child was run over and killed by a careless coachman. A pensioned officer saw this through the window. His description was quite characteristic. It was the anniversary of a certain battle. The old gentleman, who stood by the window thinking about it and about his long dead comrades, was looking blankly out into the street. The horrible cry of the unhappy child woke him up and he really began to see. Then he observed that he had in truth seen everything that had happened before the child was knocked over—i. e., for some reason the coachman had turned around, turning the horses in such a way at the same time that the latter jumped sidewise upon the frightened child, and hence the accident. The general expressed himself correctly in this fashion: "I saw it all, but I did not perceive and know that I saw it until after the scream of the child." He offered also in proof of the correctness of his testimony, that he, an old cavalry officer, would have had to see the approaching misfortune if he had consciously seen the moving of the coachman, and then he would have had to be frightened. But he knew definitely that he was frightened only when the child cried out—he could not, therefore, have consciously perceived the preceding event. His story was confirmed by other witnesses.

This psychological process is of significance in criminal trials, inasmuch as many actionable cases depend upon sudden and unexpected events, where retrospective illumination may frequently come in. In such cases it is most important to determine what actually has been perceived, and it is never indifferent whether we take the testimony in question as true or not.

With regard to the senses of criminals, Lombroso and Ottolenghi have asserted that they are duller than those of ordinary people. The assertion is based on a collection made by Lombroso of instances of the great indifference of criminals to pain. But he has overlooked the fact that the reason is quite another thing. Barbarous living and barbarous morals are especially dulling, so that indifference to pain is a characteristic of all barbarous nations and characters. Inasmuch as there are many criminals among barbarous people, barbarity, criminality and indifference to pain come together in a

large number of cases. But there is nothing remarkable in this, and a direct relation between crime and dullness of the senses can not be demonstrated.

(b) The Sense of Sight.
Section 37. (I) General Considerations.

Just as the sense of sight is the most dignified of all our senses, it is also the most important in the criminal court, for most witnesses testify as to what they have seen. If we compare sight with the hearing, which is next in the order of importance, we discover the well-known fact that what is seen is much more certain and trustworthy than what is heard. "It is better to see once than to hear ten times," says the universally-valid old maxim. No exposition, no description, no complication which the data of other senses offer, can present half as much as even a fleeting glance. Hence too, no sense can offer us such surprises as the sense of sight. If I imagine the thunder of Niagara, the voice of Lucca, the explosion of a thousand cartridges, etc., or anything else that I have not heard, my imagination is certainly incorrect, but it will differ from reality only in degree. It is quite different with visual imagination. We need not adduce examples of magnificence like the appearance of the pyramids, a tropical light; of a famous work of art, a storm at sea, etc. The most insignificant thing ever seen but variously pictured in imagination will be greeted at first sight with the words: "But I imagined it quite different!" Hence the tremendous importance of every local and material characteristic which the criminal court deals with. Every one of us knows how differently he has, as a rule, imagined the place of the crime to be; how difficult it is to arrive at an understanding with the witness concerning some unseen, local characteristic, and how many mistakes false images of the unseen have caused. Whenever I ciceroned anybody through the Graz Criminal Museum, I was continually assailed with "Does this or that look so? But I thought it looked quite different!" And the things which evoke these exclamations are such as the astonished visitors have spoken and written about hundreds of times and often passed judgments upon. The same situation occurs when witnesses narrate some observation. When the question involves the sense of hearing some misunderstanding may be popularly assumed. But the people know little of optical illusions and false visual perceptions, though they are aware that incorrect auditions are frequent matters of fact. Moreover, to the heard object

a large number of more or less certain precautionary judgments are attached. If anybody, e. g., has heard a shot, stealthy footsteps, crackling flames, we take his experience always to be approximate. We do not do so when he assures us he has seenthese things or their causes. Then we take them—barring certain mistakes in observation,—to be indubitable perceptions in which misunderstanding is impossible.

In this, again, is the basis for the distrust with which we meet testimony concerning hearsay. For we feel uncertain in the mere absence of the person whose conversation is reported, since his value can not be determined. But a part of the mistrust lies in the fact that it is not vision but the perennially half-doubted hearing that is in issue. Lies are assigned mainly to words; but there are lies which are visual (deceptions, maskings, illusions, etc.). Visual lies are, however, a diminishing minority in comparison with the lies that are heard.

The certainty of the correctness of vision lies in its being tested with the sense of touch,—i. e. in the adaptation of our bodily sense to otherwise existing things. As Helmholtz says, "The agreement between our visual perceptions and the external world, rests, at least in the most important matters, on the same ground that all our knowledge of the actual world rests on, upon the experience and the lasting test of their correctness by means of experiments, i. e., of the movements of our bodies." This would almost make it seem that the supreme judge among the senses is the touch. But that is not intended; we know well enough to what illusions we are subject if we trust the sense of touch alone. At the same time we must suppose that the question here is one of the nature of the body, and this can be measured only by something similar, i.e., by our own physical characteristics, but always under the control of some other sense, especially the sense of sight.

The visual process itself consists, according to Fischer, "of a compounded series of results which succeed each other with extraordinary rapidity and are causally related. In this series the following elements may principally be distinguished.

(1) The physico-chemical process.

(2) The physiologico-sensory.

(3) The psychological.

(4) The physiologico-motor.

(5) The process of perception." It is not our task to examine the first four elements. In order

clearly to understand the variety of perception, we have to deal with the last only. I once tried to explain this by means of the phenomenon of instantaneous photographs (cinematographs). If we examine one such representing an instant in some quick movement, we will assert that we never could have perceived it in the movement itself. This indicates that our vision is slower than that of the photographic apparatus, and hence, that we do not apprehend the smallest particular conditions, but that we each time unconsciously compound a group of the smallest conditions and construct in that way the so-called instantaneous impressions. If we are to compound a great series of instantaneous impressions in one galloping step, we must have condensed and compounded a number of them in order to get the image that we see with our eyes as instantaneous. We may therefore say that the least instantaneous image we ever see with our eyes contains many parts which only the photographic apparatus can grasp. Suppose we call these particular instances a, b, c, d, e, f, g, h, i, j, k, l, m; it is self-evident that the manner of their composition must vary with each individual. One man may compound his elements in groups of three: a, b, c,—d, e, f,—g, h, i, etc.; another may proceed in dyads: a, b,—c, d,—e, f,—g, h,—etc.; a third may have seen an unobservable instant later, but constructs his image like the first man: b, c, d,—l, m, n, etc.; a fourth works slowly and rather inaccurately, getting: a, c, d,—f, h, i,—etc. Such variations multiply, and when various observers of the same event describe it they do it according to their different characteristics. And the differences may be tremendous. Substitute numerals for letters and the thing becomes clear. The relative slowness of our apprehension of visual elements has the other consequence that we interpolate objects in the lacunæ of vision according to our expectations. The best example of this sort of thing would be the perception of assault and battery. When ten people in an inn see how A raises a beer glass against B's head, five expect: "Now he'll pound him," and five others: "Now he'll throw it." If the glass has reached B's head none of the ten observers have seen how it reached there, but the first five take their oath that A pounded B with the glass, and the other five that he threw it at B's head. And all ten have really seen it, so firmly are they convinced of the correctness of their swift judgment of expectation. Now, before we treat the witness to some reproach like untruth, inattention, silliness, or something equally nice, we had better consider whether his story is not true, and whether the difficulty might not really lie in the imperfection of our own sensory processes. This involves partly what Liebmann has called "anthropocentric vision," i. e., seeing with man as the center of things. Liebmann further asserts, "that we see things only in perspective sizes, i. e., only from an angle of vision varying with their approach, withdrawal and change of position, but in no sense as definite cubical, linear, or surface sizes. The apparent size of an object we call an angle of vision at a certain distance. But, what indeed is the different, true size? We know only relations of magnitude." This description is important when we are dealing with testimony concerning size. It seems obvious that each witness who speaks of size is to be asked whence he had observed it, but at the same time a great many unexpected errors occur, especially when what is involved is the determination of the size of an object in the same plane. One need only to recall the meeting of railway tracks, streets, alleys, etc., and to remember how different in size, according to the point of view of the witness, various objects in such places must appear. Everybody knows that distant things seem smaller than near ones, but almost nobody knows what the difference amounts to. For examples see Lotze, "Medical Psychology," Leipzig, 1852.

In addition we often think that the clearness of an object represents its distance and suppose that the first alone determines the latter. But the distinctness of objects, i. e., the perceptibility of a light-impression, depends also upon the absolute brightness and the differences in brightness. The latter is more important than is supposed. Try to determine how far away you can see a key-hole when the wall containing the door is in the shadow, and when there is a window opposite the key-hole. A dark object of the size of a key-hole will not be visible at one hundredth of the distance at which the key-hole is perceived. Moreover, the difference in intensity is not alone in consideration; the intensity of the object with regard to its background has yet to be considered. Aubert has shown that the accuracy of the distinction is the same when a square of white paper is looked at from an angle of 18", and when conversely a square of black paper on white background is looked at from an angle of 85". "When we put a gray paper in the sunshine, it may become objectively brighter than white paper in shadow. But this does not prevent us from knowing one as gray and the other as pure white. We separate the color of the object from the intensity of the incident light." But this is not always so simple, inasmuch as

we know in the case in hand which paper is gray and which white, which is in the sunlight and which in the shadow. But if these facts are not known mistakes often occur so that a man dressed in dark clothes but in full light will be described as wearing lighter clothes than one who wears light clothes in the shadow.

Differences of illumination reveal a number of phenomena difficult to explain. Fechner calls attention to the appearance of stars: "At night everybody sees the stars, in daylight not even Sirius or Jupiter is seen. Yet the absolute difference between those places in the heavens where the stars are and the environing places is just as great as in the night—there is only an increase in illumination." Of still greater importance to us is the circumstance noted but not explained by Bernstein. If, in daylight, we look into a basement room from outside, we can perceive nothing, almost; everything is dark, even the windows appear black. But in the evening, if the room is ever so slightly illuminated, and we look into it from outside, we can see even small articles distinctly. Yet there was much intenser light in the room in question during the day than the single illumination of the night could have provided. Hence, it is asserted, the difference in this case is a standard one. In open day the eye is accustomed to the dominating brightness of daylight, beside which the subdued illumination of the room seems relatively dark. But in the evening one is in the dark, and hence even the little light of a single candle is enough to enable one to see. That this explanation is untrue is shown by the fact that the phenomenon is not regulated even when the circumstances in question are made identical. If, for example, you approach the window in daylight with your eyes shut, lean your forehead against the pane and shut out the light on the sides with your hands, and then open your eyes, you see as little in the room as when you looked into it without performing this ceremony. So again, if during the night you gazed at some near-by gas lamp and then glanced into the room, there is only a few moments' indistinctness at most, after that the single candle is enough. The reason, then, must be different from the assigned one—but whatever it is, we need only to maintain that immediate judgment concerning numerous cases involving situations of this kind would be overhasty. It is often said that a witness was able to see this or that under such and such illumination, or that he was unable to see it, although he denies his ability or inability. The only solution of such contradictions is an experiment. The attempt must be made either by the judge or some reliable

third person, to discover whether, under the same conditions of illumination, anything could be seen at the place in question or not.

As to what may be seen in the distance, experiment again, is the best judge. The human eye is so very different in each man that even the acute examination into what is known of the visual image of the Pleiades shows that the average visual capacity of classic periods is no different from our own, but still that there was great variety in visual capacity. What enormous visual power is attributed to half-civilized and barbarous peoples, especially Indians, Esquimos, etc.! Likewise among our own people there are hunters, mountain guides, etc., who can see so clearly in the distance that mere stories about it might be fables. In the Bosnian campaign of 1878 we had a soldier who in numerous cases of our great need to know the enemy's position in the distance could distinguish it with greater accuracy than we with our good field-glasses. He was the son of a coal-miner in the Styrian mountains, and rather a fool. Incidentally it may be added that he had an incredible, almost animal power of orientation.

As we know little concerning far-sightedness, so also we are unable to define what near-sighted people can see. Inasmuch as their vision does not carry, they are compelled to make intellectual supplementations. They observe the form, action, and clothes of people more accurately than sharp-eyed persons, and hence recognize acquaintances at a greater distance than the latter. Therefore, before an assertion of a short-sighted man is doubted an experiment should be made, or at least another trustworthy short-sighted person should be asked for his opinion.

The background of objects, their movement and form have decided effects on the difference in visual perception. It is an ancient observation that lengthy objects like poles, wires, etc., are visible at incomparably greater distances than, e. g., squares of the same length. In examination it has been shown that the boundary of accurate perception can hardly be determined. I know a place where under favorable illumination taut, white and very thin telephone wires may be seen at a distance of more than a kilometer. And this demands a very small angle of vision.

Humboldt calls attention to the large number of "optical fables." He assures us that it is certainly untrue that the stars may be seen in daylight from a deep well, from mines, or high mountains, although this has been repeatedly affirmed since Aristotle.

The explanation of our power to see very thin, long objects at

a very great distance, is not our affair, but is of importance because it serves to explain a number of similar phenomena spoken of by witnesses. We have either incorrectly to deny things we do not understand, or we have to accept a good deal that is deniable. We will start, therefore, with the well-known fact that a point seen for a considerable time may easily disappear from perception. This has been studied by Helmholtz and others, and he has shown how difficult it is to keep a point within the field of vision for only ten or twenty minutes. Aubert examines older studies of the matter and concludes that this disappearance or confusion of an object is peripheral, but that fixation of a small object is always difficult. If we fix a distant point it is disappearing at every instant so that an accurate perception is not possible; if however we fix upon a long, thin body, e. g., a wire, it is unnecessary to fix a single point and we may see the object with a wandering eye, hence more clearly.

Helmholtz adds that weakly objective images disappear like a wet spot on warm tin, at the moment a single point is fixed, as does e. g., a landscape seen at night. This last acute observation is the basis of many a testimony concerning the sudden disappearance of an object at night. It has helped me in many an examination, and always to advantage.

In this connection the over-estimation of the moon's illuminating power is not to be forgotten. According to Helmholtz the power of the full moon is not more than that of a candle twelve feet away. And how much people claim to have seen by moonlight! Dr. Vincent[1] says that a man may be recognized during the first quarter at from two to six meters, at full moon at from seven to ten meters, and at the brightest full moon, an intimate may be recognized at from fifteen to sixteen meters. This is approximately correct and indicates how much moonlight is over-estimated.

In addition to the natural differences of sight there are also those artificially created. How much we may help ourselves by skilful distinctions, we can recognize in the well-known and frequently-mentioned business of reading a confused handwriting. We aim to weaken our sense-perception in favor of our imagination, i. e. so to reduce the clearness of the former as to be able to test upon it in some degree a larger number of images. We hold the MS. away from us, look at it askant, with contracted eyebrows, in different lights, and finally we read it. Again, the converse occurs. If we have seen something with a magnifying glass we later recognize

details without its help. Definite conditions may bring to light very great distinctions. A body close to the face or in the middle distance looks different according as one eye or both be used in examining it. This is an old story and explains the queer descriptions we receive of such objects as weapons and the like, which were suddenly held before the face of the deponent. In cases of murderous assault it is certain that most uncanny stories are told, later explained by fear or total confusion or intentional dishonesty, but really to be explained by nothing more than actual optical processes.

I do not believe that binocular vision is of much importance in the law; I know of no case in ordinary vision where it matters whether one or both eyes have been used. It is correct to assert that one side or the other of a vertically held hand will be clearer if, before looking at it with both eyes, you look at it with one or the other, but this makes little difference to our purpose. It must be maintained that a part of what we see is seen with one eye only,—if, e. g., I look at the sky and cover one eye with my hand, a certain portion of the heaven disappears, but I observe no alteration in the remaining portion. When I cover the other eye, other stars disappear. Therefore, in binocular vision certain things are seen with one eye only. This may be of importance when an effect has been observed first with both eyes, then with one; raising the question of the difference in observation—but such a question is rare.

There are two additional things to consider. The first is the problem of the influence of custom on increasing visual power in darkness. This power is as a rule undervalued. No animal, naturally, can see anything in complete darkness. But it is almost unbelievable how much can be seen with a very little light. Here again, prisoners tell numerous stories concerning their vision in subterranean prisons. One saw so well as to be able to throw seven needles about the cell and then to find them again. Another, the naturalist Quatre-mére-Disjonval, was able so accurately to observe the spiders in his cell as to make the observation the basis for his famous "Aranéologie." Aubert tells of his having had to stay in a room so dark as to make it necessary for others to feel their way, but nevertheless being able to read books without detection because the others could not see the books.

How quickly we get used to darkness and how much more we see after a while, is well known. It is also certain that the longer you are in darkness the more you see. You see more at the end of a day than after a few hours, and at the end of a year, still more. The

eye, perhaps, changes in some degree for just this purpose. But a prolonged use of the visual mechanism tends to hypertrophy— or atrophy, as the eyes of deep-sea fishes show. It is well, in any event, to be careful about contradicting the testimonies of patients who have long lived in the dark, concerning what they have seen. The power to see in the dark is so various that without examination, much injustice may be done. Some people see almost nothing at twilight, others see at night as well as cats. And in court these differences must be established and experimentally verified.

The second important element is the innervation of the muscles in consequence of movement merely seen. So Stricker points out, that the sight of a man carrying a heavy load made him feel tension in the muscles involved, and again, when he saw soldiers exercising, he almost was compelled openly to act as they. In every case the muscular innervation followed the visual stimulus.

This may sound improbable but, nevertheless, everybody to some degree does the identical things. And at law the fact may be of importance in cases of assault and battery. Since I learned it, I have repeatedly observed in such cases, from harmless assault to murder, that people, although they had not been seen to deal any blows, were often accused of complicity simply because they were making suspicious movements that led to the following inference: "They stuck their hands into their trousers pocket looking for a knife, clenched their fists, looked as if they were about to jump, swung their hands." In many such cases it appeared that the suspects were harmless spectators who were simply more obvious in their innervation of the muscles involved in the assault they were eagerly witnessing. This fact should be well kept in mind; it may relieve many an innocent.

Section 38. (2) Color Vision.

Concerning color vision only a few facts will be mentioned: 1. It will be worth while, first of all, to consider whether color exists. Liebmann holds that if all the people were blind to red, red would not exist; red, i. e., is some cervical phantasy. So are light, sound, warmth, taste, etc. With other senses we have another world. According to Helmholtz, it is senseless to ask whether cinnabar is red as we see it or is only so as an optical illusion. "The sensation of red is the normal reaction of normally constructed eyes to light reflected from cinnabar. A person blind to red, will see cinnabar as black, or a dark grayish yellow, and this is the correct reaction

for these abnormal eyes. But he needs to know that his eyes are different from those of other people. In itself the sensation is neither more correct nor less correct than any other even though those who can see red are in the great majority. The red color of cinnabar exists as such only in so far as there are eyes which are similar to those of the majority of mankind. As such light reflected from cinnabar may not properly be called red; it is red only for especial kinds of eyes." This is so unconditionally incorrect that an impartial judge of photography says[1] that everything that normal eyes call violet and blue, is very bright, and everything they call green and red is very dark. The red-blind person will see as equal certain natural reds, greens and gray-yellows, both in intensity and shadow. But on the photograph he will be able to distinguish the differences in brightness caused by these three otherwise identical colors. We may, therefore, assume that colors possess objective differences, and that these objective differences are perceived even by persons of normal vision. But whether I am able to sense the same effect in red that another senses, and whether I should not call red blue, if I had the color-vision of another, is as impossible to discover as it is useless. When the question of color is raised, therefore, we will try to discover only whether the person in question has normal color-vision, or what the nature and degree of his abnormality may be.

2. It is not unimportant to know whether single tints are recognizable in the distance. There have been several examinations of this fact. Aubert[2] constructed double squares of ten millimeters and determined the angle of vision at which the color as such could be seen. His results were:

It is interesting to notice that the angle for blue on a white background is almost nine times that for white, orange, or yellow on a black background. In cases where colors are of importance, therefore, it will be necessary to discover the color and the nature of its background before the accuracy of the witness can be established.

3. It is well known that in the diminution of brightnesses red disappears before blue, and that at night, when all colors have disappeared, the blue of heaven is still visible. So if anybody asserts that he has been able to see the blue of a man's coat but not his red-brown trousers, his statement is possibly true, while the converse would be untrue. But there are no reliable or consonant accounts of the order in which colors disappear in increasing darkness. The knowledge of this order would help a great deal in the administration of criminal justice.

4. The retina will not see red at the periphery, because there are no red rods there. A stick of red sealing wax drawn across the eye from right to left, appears at the periphery of the visual field to be black. If, then, a witness has not looked right at a definitely red object, and has seen it askance, he has certainly not observed its color. The experiment may be made by anybody.

5. According to Quantz[3] objects in less refractable colors (red, orange, yellow, and purple) look 0.2 to 3.6% bigger against white, while blue, blue-green, and violet objects appear from 0.2 to 2.2% smaller. Dark and long-lined objects seem longer; bright and horizontal seem wider. And these facts are significant when witnesses judge of size.

6. If colors are observed through small openings, especially through very small holes, the nuances become essentially different and green may even seem colorless.

7. According to Aubert, sparkle consists of the fact that one point in a body is very bright while the brightness diminishes almost absolutely from that point; e. g., a glancing wire has a very narrow bright line with deep shadows on each side; a ball of mercury in a thermometer, a shining point and then deep shadow. When we see this we say it sparkles because we unite it with a number of similar observations. It is therefore conceivable that at a great distance, under conditions of sharp or accidental illuminations, etc., we are likely to see things as sparkling which do not do so in the least. With the concept "sparkling," moreover, we tend to unite,

at least under certain circumstances, definite images, and hence "glancing weapons" are often seen in places where there were only quite harmless dull objects. So also coins are seen to sparkle where really there are none.

Section 39. (3) The Blind Spot.

Everybody knows what the blind spot is, and every psychology and physiology text-book talks about it. But as a rule it is identified only with the little point and the tiny cross pictured in the textbooks, and it is supposed that it does not much matter if the little cross, under certain circumstances, can not be seen. But it must not be forgotten that the size of the blind spot increases with the distance so that at a fairly great distance, possibly half the length of a room, the blind spot becomes so great that a man's head may disappear from the field of vision. According to Helmholtz: "The effect of the blind spot is very significant. If we make a little cross on a piece of paper and then a spot the size of a pea two inches to the right, and if we look at the cross with the left eye closed, the spot disappears. The size of the blind spot is large enough to cover in the heavens a plate which has twelve times the diameter of the moon. It may cover a human face at a distance of 6', but we do not observe this because we generally fill out the void. If we see a line in the place in question, we see it unbroken, because we know it to be so, and therefore supply the missing part."

A number of experiments have been made with more or less success to explain the blind spot. It is enough for us to agree that we see habitually with both eyes and that the "spot as big as a pea" disappears only when we look at the cross. But when we fix our eyes on anything we pay attention to that only and to nothing else. And it is indifferent to us if an uninteresting object disappears, so that the moment we begin to care about the "spot as large as a pea," it is immediately to hand and needs no imaginative completion. If it be objected that fixing with the eyes and being interested are not identical, we reply that a distinction is made only in experiment. You fix one point and are interested in the other because you expect it to disappear. And this experiment, as anybody will immediately recognize, has its peculiar difficulty, because it requires much concentration not to look at the point which interests us. This never happens in the daily life, and it will not be easy to fix a point which is not interesting.

At the same time there are conceivable cases in which objects

seen askance may be of importance, and where the visual fixation of a single point will not reveal every reflection that fell on the blind spot. I have not met with a practical case in which some fact or testimony could be explained only by the blind spot, but such cases are conceivable.

Section 40. (c) The Sense of Hearing.

We have two problems with regard to sound—whether the witnesses have heard correctly, and whether we hear them correctly. Between both witnesses and ourselves there are again other factors. Correct comprehension, faithful memory, the activity of the imagination, the variety of influences, the degree of personal integrity; but most important is the consideration, whether the witness has heard correctly. As a general thing we must deny in most cases completely accurate reproduction of what witnesses have heard. In this connection dealing with questions of honor is instructive. If the question is the recall of slander the terms of it will be as various as the number of witnesses. We discover that the sense, the tendency of slander is not easily mistaken. At least if it is, I have not observed it. The witness, e. g., will confuse the words "scamp," "cheat," "swindler," etc., and again the words: "ox," "donkey," "numbskull," etc. But he will not say that he has heard "scamp" where what was said was "donkey." He simply has observed that A has insulted B with an epithet of moral turpitude or of stupidity and under examination he inserts an appropriate term. Often people hear only according to meanings and hence the difficulty of getting them to reproduce verbally and directly something said by a third person. They always engage upon indirect narration because they have heard only the meaning, not the words. Memory has nothing to do with this matter, for when in examination, a witness is requested to reproduce directly what he has just heard, he will reproduce no more than the sense, not the words. Not to do so requires an unusual degree of intelligence and training.

Now if the witnesses only reproduced the actual meaning of what they heard, no harm would be done, but they tell us only what they suppose to be the meaning, and hence we get a good many mistakes. It does seem as if uneducated and half-educated people are able to shut their ears to all things they do not understand. Even purely sensory perception is organized according to intelligent capacity.

If this is kept in mind it will be possible correctly to interpret testimonies in those difficult instances in which one man narrates

what he has heard from another concerning his own statement, and where it might be quite impossible to judge the nature and culture of this third person. There are a few other conditions to consider besides.

If we have to discover a person's hearing power or his hearing power under definite conditions, it is best never to depend, in even slightly important cases, on vocal tests merely. The examination must be made by experts, and if the case is really subtle it must be made under the same circumstances of place and condition, and with the same people as in the original situation. Otherwise nothing certain can be learned.

The determination of auditory power is, however, insufficient, for this power varies with the degree any individual can distinguish a single definite tone among many, hear it alone, and retain it. And this varies not only with the individual but also with the time, the place, the voice, etc. In my bed-room, e. g., and in three neighboring rooms I have wall-clocks each of which is running. The doors of the room are open right and left. At night when everything is quiet, I can sometimes hear the ticking of each one of these clocks; immediately isolate one completely and listen to that so that the ticking of the other three completely disappears. Then again I may kindly command myself not to hear this ticking, but to hear one of the other three, and I do so, though I fail to hear two clocks together at just the same instant. On another day under similar circumstances I completely fail in this attempt. Either I hear none of the clocks in particular, or only for a short time, which results in the ticking's being again lost in the general noise; or I do hear the ticking of one clock, but never of that which I have chosen to hear.

This incident is variously explicable and the experiment may be repeated with various persons. It indicates that auditory capacity is exceedingly differentiated and that there is no justification for aprioristic doubt of especial powers. It is, however, admittedly difficult to say how experiments can be made under control.

There are still a few more marvels. It is repeatedly asserted, e. g., by Tyndall, that a comparatively large number of people do not hear high tones like the chirping of crickets, although the normal hearing of such people is acute. Others again easily sense deep tones but distinguish them with difficulty because they retain only a roll or roar, but do not hear the individual tones.[1] And generally,

almost all people have difficulty in making a correct valuation of the direction of sound. Wundt says that we locate powerful sounds in front of us and are generally better able to judge right and left than before and behind.[2] These data, which are for us quite important, have been subjected to many tests. Wundt's statement has been confirmed by various experiments which have shown that sound to the right and the left are best distinguished, and sounds in front and below, in front to the right and to the left, and below, to the right and to the left, are least easily distinguished. Among the experimenters were Preyer, Arnheim, Kries, Münsterberg.

All these experiments indicate certain constant tendencies to definite mistakes. Sounds in front are often mistaken for sounds behind and felt to be higher than their natural head-level. Again, it is generally asserted that binaural hearing is of great importance for the recognition of the direction of sound. With one ear this recognition is much more difficult. This may be verified by the fact that we turn our heads here and there as though to compare directions whenever we want to make sure of the direction of sound. In this regard, too, a number of effective experiments have been made.

When it is necessary to determine whether the witness deposes correctly concerning the direction of sound, it is best to get the official physician to find out whether he hears with both ears, and whether he hears equally well with both. It is observed that persons who hear excellently with both ears are unfortunate in judging the direction of sound. Others again are very skilful in this matter, and may possibly get their skill from practice, sense of locality, etc. But in any case, certainty can be obtained only by experimentation.

With regard to the conduction of sound—it is to be noted that sound is carried astonishingly far by means of compact bodies. The distance at which the trotting of horses, the thunder of cannons, etc., may be heard by laying the ear close to the ground is a commonplace in fiction. Therefore, if a witness testifies to have heard something at a great distance in this way, or by having laid his ear to the wall, it is well not to set the evidence aside. Although it will be difficult in such cases to make determinative experiments, it is useful to do so because the limits of his capacity are then approximated.

Under certain circumstances it may be of importance to know what can be heard when the head, or at least the ear, is under water. The experiment may be made in the bath-room, by setting the back of the head under water so that the ears are completely covered

but the mouth and the eyes are free. The mouth must be kept closed so that there shall be no intrusion of sound through the Eustachian tube. In this condition practically no sound can be heard which must first pass through the air. If, therefore, anybody even immediately next to you, speaks ever so loud, you can hear only a minimum of what he says. On the other hand, noises that are conducted by compact bodies, i. e. the walls, the bath, and the water, can be heard with astonishing distinctness, especially if the bath is not detachable but is built into the wall. Then if some remote part of the building, e. g. some wall, is knocked, the noise is heard perfectly well, although somebody standing near the bath hears nothing whatever. This may be of importance in cases of accident, in certain attempts at drowning people, and in accidental eaves-dropping.

There are several things to note with regard to deaf persons, or such as have difficulty with their hearing. According to Fechner, deafness begins with the inability to hear high tones and ends with the inability to hear deep ones, so that it often happens that complainants are not believed because they still hear deep tones. Again, there are mistakes which rise from the fact that the deaf often learn a great deal from the movements of the lips, and the reading of these movements has become the basis of the so-called "audition" of deaf mutes. There are stories of deaf mutes who have perceived more in this way, and by means of their necessary and well-practised synthesis of impressions, than persons with good hearing power.

The differences that age makes in hearing are of importance. Bezold has examined a large number of human ears of different ages and indicates that after the fiftieth year there is not only a successive decrease in the number of the approximately normal-hearing, but there is a successively growing increase in the degree of auditory limitation which the ear experiences with increasing age. The results are more surprising than is supposed.

Not one of 100 people over fifty years of age could understand conversational speech at a distance of sixteen meters; 10.5% understood it at a distance of eight to sixteen meters. Of school children 46.5% (1918 of them) from seven to eighteen understood it at a distance of 20 meters plus, and 32.7% at a distance of from 16 to 8 meters. The percentage then is 10.5 for people over fifty as against 79.2 of people over seven and under 18. Old women can hear better than old men. At a distance of 4 to 16 meters the proportion of women to men who could hear was 34 to 17. The converse is

true of children, for at a distance of 20 meters and more the percentage of boys was 49.9 and girls 43.2. The reason for this inversion of the relation lies in the harmful influences of manual labor and other noisy occupations of men. These comparisons may be of importance when the question is raised as to how much more a witness may have heard than one of a different age.

Section 41. (d) The Sense of Taste.

The sense of taste is rarely of legal importance, but when it does come into importance it is regularly very significant because it involves, in the main, problems of poisoning. The explanation of such cases is rarely easy and certain—first of all, because we can not, without difficulty, get into a position of testing the delicacy and acuteness of any individual sense of taste, where such testing is quite simple with regard to seeing and hearing. At the same time, it is necessary when tests are made, to depend upon general, and rarely constant impressions, since very few people mean the same thing by, stinging, prickly, metallic, and burning tastes, even though the ordinary terms sweet, sour, bitter, and salty, may be accepted as approximately constant. The least that can be done when a taste is defined as good, bad, excellent, or disgusting, is to test it in every possible direction with regard to the age, habits, health, and intelligence of the taster, for all of these exercise great influence on his values. Similarly necessary are valuations like flat, sweetish, contractile, limey, pappy, sandy, which are all dictated by almost momentary variations in well-being.

But if any denotation is to be depended upon, and in the end some one has to be, it is necessary to determine whether the perception has been made with the end or the root of the tongue.[1] Longet, following the experiments of certain others, has brought together definite results in the following table:

In such cases too, particularly as diseased conditions and personal idiosyncrasies exercise considerable influences, it will be important to call in the physician. Dehn is led by his experiments to the conclusion that woman's sense of taste is finer than man's, and again that that of the educated man finer than that of the uneducated. In women education makes no difference in this regard.

Section 42. (e) The Sense of Smell.

The sense of smell would be of great importance for legal consideration if it could get the study it deserves. It may be said that many men have more acute olfactory powers than they know, and that they may learn more by means of them than by means of the other senses. The sense of smell has little especial practical importance. It only serves to supply a great many people with occasional disagreeable impressions, and what men fail to find especially necessary they do not easily make use of. The utility of smell would be great because it is accurate, and hence powerful in its associative quality. But it is rarely attended to; even when the associations are awakened they are not ascribed to the sense of smell but are said to be accidental. I offer one example only, of this common fact. When I was a child of less than eight years, I once visited with my parents a priest who was a school-mate of my father's. The day spent in the parsonage contained nothing remarkable, so that all these years I have not even thought of it. A short time ago all the details I encountered on that day occurred to me very vividly, and inasmuch as this sudden memory seemed baseless, I studied carefully the cause of its occurrence, without success. A short time later I had the same experience and at the same place. This was a clew, and I then recalled that I had undertaken a voyage of discovery with the small niece of the parson and had been led into a fruit cellar. There I found great heaps of apples laid on straw, and on the wall a considerable number of the hunting boots of the parson. The mixed odors of apple, straw and boots constituted a unique and long unsmelled perfume which had sunk deep into my memory. And as I passed a room which contained the same elements of odor, all those things that were associated with that odor at the time I first smelt it, immediately recurred.

Everybody experiences such associations in great number, and in examinations a little trouble will bring them up, especially when the question deals with remote events, and a witness tells about some "accidental" idea of his. If the accident is considered to be

an association and studied in the light of a memory of odor, one may often succeed in finding the right clew and making progress.

But accurate as the sense of smell is, it receives as a rule little consideration, and when some question concerning smell is put the answer is generally negative. Yet in no case may a matter be so easily determined as in this one; one may without making even the slightest suggestion, succeed in getting the witness to confess that he had smelled something. Incidentally, one may succeed in awakening such impressions as have not quite crossed the threshold of consciousness, or have been subdued and diverted. Suppose, e. g., that a witness has smelled fire, but inasmuch as he was otherwise engaged was not fully conscious of it or did not quite notice it, or explained it to himself as some kitchen odor or the odor of a bad cigar. Such perceptions are later forgotten, but with proper questioning are faithfully and completely brought to memory.

Obviously much depends on whether anybody likes certain delicate odors or not. As a rule it may be held that a delicate sense of smell is frequently associated with nervousness. Again, people with broad nostrils and well developed foreheads, who keep their mouths closed most of the time, have certainly a delicate sense of smell. People of lymphatic nature, with veiled unclear voices, do not have a keen sense of smell, and still duller is that of snufflers and habitual smokers. Up to a certain degree, practice may do much, but too much of it dulls the sense of smell. Butchers, tobacconists, perfumers, not only fail to perceive the odors which dominate their shops; their sense of smell has been dulled, anyway. On the other hand, those who have to make delicate distinctions by means of their sense, like apothecaries, tea dealers, brewers, wine tasters, etc. achieve great skill. I remember that one time when I had in court to deal almost exclusively with gypsies, I could immediately smell whether any gypsies had been brought there during the night.

Very nervous persons develop a delicateness and acuteness of smell which other persons do not even imagine. Now we have no real knowledge of how odors arise. That they are not the results of the radiation of very tiny parts is shown by the fact that certain bodies smell though they are known not to give off particles. Zinc, for example, and such things as copper, sulphur, and iron, have individual odors; the latter, particularly when it is kept polished by a great deal of friction,—e.g., in the cases of chains, key-rings kept in the pocket.

In defining the impressions of smell great difficulties occur. Even normal individuals often have a passionate love for odors that are either indifferent or disgusting to others (rotten apples, wet sponges, cow-dung, and the odor of a horse-stable, garlic, assafoetida, very ripe game, etc.). The same individual finds the odor of food beautiful when hungry, pleasant when full-fed, and unendurable when he has migraine. It would be necessary to make an accurate description of these differences and all their accompanying circumstances. With regard to sex, the sense of smell, according to Lombroso,[1] is twice as fine in men as in women. This is verified by Lombroso's pupils Ottolenghi and Sicard, Roncoroni and Francis Galton. Experience of daily life does not confirm this, though many smokers among men rarely possess acute sense of smell, and this raises the percentage considerably in favor of women.

Section 43. (f) The Sense of Touch.

I combine, for the sake of simplicity, the senses of location, pressure, temperature, etc., under the general expression: sense of touch. The problem this sense raises is no light one because many witnesses tell of perceptions made in the dark or when they were otherwise unable to see, and because much is perceived by means of this sense in assaults, wounds, and other contacts. In most cases such witnesses have been unable to regard the touched parts of their bodies, so that we have to depend upon this touch-sense alone. Full certainty is possible only when sight and touch have worked together and rectified one another. It has been shown that the conception of the third dimension can not be obtained through the sense of sight. At the beginning we owe the perception of this dimension only to touch and later on to experience and habit. The truth of this statement is confirmed by the reports of persons who, born blind, have gained sight. Some were unable to distinguish by means of mere sight a silver pencil-holder from a large key. They could only tell them to be different things, and recognized their nature only after they had felt them. On the other hand, the deceptive possibilities in touch are seen in the well-known mistakes to which one is subjected in blind touching. At the same time practice leads to considerable accuracy in touch and on many occasions the sense is trusted more than sight—e. g., whenever we test the delicacy of an object with our finger-tips. The fineness of paper, leather, the smoothness of a surface, the presence of points,

are always tested with the fingers. So that if a witness assures us that this or that was very smooth, or that this surface was very raw, we must regularly ask him whether he had tested the quality by touching it with his fingers, and we are certain only if he says yes. Whoever has to depend much on the sense of touch increases its field of perception, as we know from the delicacy of the sense in blind people. The statements of the blind concerning their contact sensations may be believed even when they seem improbable; there are blind persons who may feel the very color of fabrics, because the various pigments and their medium give a different surface-quality to the cloth they color.

In another direction, again, it is the deaf who have especial power. So, we are assured by Abercrombie that in his medical practice he had frequently observed how deaf people will perceive the roll of an approaching wagon, or the approach of a person, long before people with good hearing do so. For a long time I owned an Angora which, like all Angoras, was completely deaf, and her deafness had been tested by physicians. Nevertheless, if the animal was dozing somewhere and anybody came near it, she would immediately notice his steps, and would distinguish them, for she would jump up frightened, if the newcomer was unknown, and would stretch herself with pleasure in the expectation of petting if she felt a friend coming. She would sense the lightest touch on the object she occupied, bench, window-seat, sofa, etc., and she was especially sensitive to very light scratching of the object. Such sensitivity is duplicated frequently in persons who are hard of hearing, and whom, therefore, we are likely to doubt.

The sense of touch is, moreover, improved not only by practice, but also by the training of the muscles. Stricker asserts that he has frequently noticed that the observational capacity of individuals who make much use of their muscles is greater than among persons whose habits are sedentary. This does not contradict the truth established by many experiments that the educated man is more sensitive in all directions than the uneducated. Again, women have a better developed sense of touch than men, the space-sense and the pressure-sense being equivalent in both sexes. On these special forms of the touch-sense injections of various kinds have decided influence. The injection of morphine, e. g., reduces the space-sense in the skin. Cannabinum tannicum reduces sensibility and alcohol is swift and considerable in its effects. According to Reichenbach some sensitives are extreme in their feeling. The

best of them notice immediately the approach and relative position of people, or the presence of another in a dark room. That very nervous people frequently feel air pressure, fine vibrations, etc., is perfectly true. And this and other facts show the great variety of touch impressions that may be distinguished. The sense of temperature has a comparatively high development, and more so in women than in men. At the lips and with the tips of the fingers, differences of two-tenths of a degree are perceived. But where an absolute valuation and not a difference is to be perceived, the mean variation, generally, is not much less than 4 degrees. E. g., a temperature of 19 degrees R. will be estimated at from 17 to 21 degrees. I believe, however, that the estimation of very common temperatures must be accepted as correct. E. g., anybody accustomed to have his room in winter 14 degrees R. will immediately notice, and correctly estimate, the rise or fall of one degree. Again, anybody who takes cold baths in summer will observe a change of one degree in temperature. It will, therefore, be possible to believe the pronouncements of witnesses concerning a narrow range of temperatures, but all the conditions of perception must be noted for the differences are extreme. It has been shown, e. g., that the whole hand finds water of 29 degrees R. warmer than water of 32 degrees R. which is merely tested with the finger. Further, Weber points out,[1] "If we put two adjacent fingers into two different warm fluids the sensations flow together in such a way that it is difficult to distinguish differences. But if we use two hands in this test, it is especially successful when we change the hands from one fluid to another. The closer the points on the skin which receive contemporary impressions and perhaps, the closer the portions of the brain to which these impressions are sent, the more easily these sensations flow together while again, the further they are from one another the less frequently does this occur." In the practice of criminal law such matters will rarely arise, but estimations of temperature are frequently required and their reliability must be established.

It is important to know what a wounded man and his enemy feel in the first instant of the crime and in what degree their testimonies are reliable. First of all, we have to thank the excellent observations of Weber, for the knowledge that we find it very difficult to discover with closed eyes the angle made by a dagger thrust against the body. It is equally difficult to determine the direction from

which a push or blow has come. On the other hand we can tell very accurately in what direction a handful of hair is pulled.

With regard to the time it takes to feel contact and pain, it is asserted that a short powerful blow on a corn is felt immediately, but the pain of it one to two seconds later. It may be that corns have an especial constitution, but otherwise the time assigned before feeling pain is far too long. Helmholtz made 1850 measurements which proved that the nervous current moves 90 feet a second. If, then, you prick your finger, you feel it a thirtieth of a second later. The easiest experiments which may be made in that regard are insufficient to establish anything definite. We can only say that the perception of a peripheral pain occurs an observable period after the shock, i. e., about a third of a second later than its cause.

The sensation of a stab is often identified as contact with a hot object, and it is further asserted that the wounded person feels close to the pain which accompanies the push or the cut, the cold of the blade and its presence in the depths of his body. So far as I have been able to learn from wounded people, these assertions are not confirmed. Setting aside individuals who exaggerate intentionally and want to make themselves interesting or to indicate considerable damage, all answers point to the fact that stabs, shots, and blows are sensed as pushes. In addition, the rising of the blood is felt almost immediately, but nothing else; pain comes much later. It is asserted by couleur-students[2] who have occasion to have a considerable number of duels behind them, that "sitting thrusts," even when they are made with the sharpest swords, are sensed only as painless, or almost painless, blows or pushes. Curiously enough all say that the sensation is felt as if caused by some very broad dull tool: a falling shingle, perhaps. But not one has felt the cold of the entering blade.

Soldiers whose shot wounds were inquired into, often just a few minutes after their being wounded, have said unanimously that they had felt only a hard push.

It is quite different with the man who causes the wound. Lotze has rightly called attention to the fact that in mounting a ladder with elastic rungs one perceives clearly the points at which the rungs are fastened to the sides. The points at which an elastic trellis is fastened is felt when it is shaken, and the resistance of the wood when an axe is used on it. In the same way the soldier senses clearly

the entrance of his sword-point or blade into the body of his enemy. The last fact is confirmed by the students. One can clearly distinguish whether the sword has merely beaten through the skin or has sunk deeply and reached the bone. And this sensation of touch is concentrated in the right thumb, which is barely under the hilt of the sword at the point where the grip rests.

The importance of the fact that the wounder feels his success lies in the possibility it gives him, when he wants to tell the truth, to indicate reliably whether and how far he has wounded his opponent. The importance of the testimony of the wounded man lies in its influence on determining, in cases where there were more than one concerned in the assault, which wound is to be assigned to which man. We often hear from the victim who really desires to tell the truth, "I was quite convinced that X dealt me the deep stab in the shoulder, but he has only pushed and not stabbed me— I did not perceive a stab." Just the same, it was X who stabbed him, and if the examining judge explains the matter to the victim, his testimony will be yet more honest.

There are still a few other significant facts.

1. It is well known that the portion of the skin which covers a bone and which is then so pulled away that it covers a fleshy part, can not easily identify the point of stimulation. Such transpositions may be made intentionally in this experiment, but they occur frequently through vigorous twists of the body. When the upper part of the body is drawn backwards, while one is sitting down, a collection of such transpositions occur and it is very hard then to localize a blow or stab. So, too, when an arm is held backward in such a way as to turn the flat of the hand uppermost. It is still more difficult to locate a wound when one part of the body is held by another person and the skin pulled aside.

2. The sensation of wetness is composed of that of cold and easy movement over surface. Hence, when we touch without warning a cold smooth piece of metal, we think that we are touching something wet. But the converse is true for we believe that we are touching something cold and smooth when it is only wet. Hence the numerous mistakes about bleeding after wounds. The wounded man or his companions believe that they have felt blood when they have only felt some smooth metal, or they have really felt blood and have taken it for something smooth and cold. Mistakes about whether there was blood or not have led to frequent confusion.

3. Repetition, and hence summation, intensifies and clarifies the

sensation of touch. As a consequence, whenever we want to test anything by touching it we do so repeatedly, drawing the finger up and down and holding the object between the fingers; for the same reason we repeatedly feel objects with pleasant exteriors. We like to move our hands up and down smooth or soft furry surfaces, in order to sense them more clearly, or to make the sensation different because of its duration and continuance. Hence it is important, every time something has to be determined through touch, to ask whether the touch occurred once only or was repeated. The relation is not the same in this case as between a hasty glance and accurate survey, for in touching, essential differences may appear.

4. It is very difficult to determine merely by touch whether a thing is straight or crooked, flat, convex or concave. Weber has shown that a glass plate drawn before the finger in such wise as to be held weakly at first, then more powerfully, then again more powerfully seems to be convex and when the reverse is done, concave. Flatness is given when the distance is kept constant.

5. According to Vierordt,[3] the motion of a point at a constant rate over a sizable piece of skin, e. g., the back of the hand from the wrist to the finger tips, gives, if not looked at, the definite impression of increasing rapidity. In the opposite direction, the definiteness is less but increases with the extent of skin covered. This indicates that mistakes may be made in such wounds as cuts, scratches, etc.

6. The problem may arise of the reliability of impressions of habitual pressure. Weber made the earliest experiments, later verified by Fechner, showing that the sensation of weight differs a great deal on different portions of the skin. The most sensitive are the forehead, the temples, the eyelids, the inside of the forearm. The most insensitive are the lips, the trunk and the finger-nails. If piles of six silver dollars are laid on various parts of the body, and then removed, one at a time, the differences are variously felt. In order to notice a removal the following number must be taken away:

One dollar from the top of the finger,

One dollar from the sole of the foot,

Two dollars from the flat of the hand,

Two dollars from the shoulder blade,

Three dollars from the heel,

Four dollars from the back of the head,

Four dollars from the breast,

Five dollars from the middle of the back,

Five dollars from the abdomen.

Further examinations have revealed nothing new. Successful experiments to determine differences between men and women, educated and uneducated, in the acuteness of the sense of pressure, have not been made. The facts they involve may be of use in cases of assault, choking, etc.

Topic 2. PERCEPTION AND CONCEPTION.

Section 44.

What lawyers have to consider in the transition from purely sensory impressions to intellectual conceptions of these impressions, is the possibility of later reproducing any observed object or event. Many so-called scientific distinctions have, under the impulse of scientific psychology, lost their status. Modern psychology does not see sharply-drawn boundaries between perception and memory, and suggests that the proper solution of the problem of perception is the solution of the problem of knowledge.[1]

With regard to the relation of consciousness to perception we will make the distinctions made by Fischer.[2] There are two spheres or regions of consciousness: the region of sensation, and of external perception. The former involves the inner structure of the organism, the latter passes from the organism into the objective world. Consciousness has a sphere of action in which it deals with the external world by means of the motor nerves and muscles, and a sphere of perception which is the business of the senses.

External perception involves three principal functions: apprehension, differentiation, and combination. Perception in the narrower sense of the term is the simple sensory conscious apprehension of some present object stimulating our eyes. We discover by means of it what the object is, its relation to ourselves and other things, its distance from us, its name, etc.

What succeeds this apprehension is the most important thing for us lawyers, i. e. recognition. Recognition indicates only that an object has sufficiently impressed a mind to keep it known and identifiable. It is indifferent what the nature of the recognized object is. According to Hume the object may be an enduring thing ("non-interrupted

and non-dependent on mind"), or it may be identical with perception itself. In the latter case the perception is considered as a logical judgment like the judgment: "It is raining," or the feeling that "it is raining," and there recognition is only the recognition of a perception. Now judgments of this sort are what we get from witnesses, and what we have to examine and evaluate. This must be done from two points of view. First, from the point of view of the observer and collector of instances who is seeking to discover the principle which governs them. If this is not done the deductions that we make are at least unreliable, and in most cases, false. As Mach says, "If once observation has determined all the facts of any natural science, a new period begins for that science, the period of deduction." But how often do we lawyers distinguish these two periods in our own work.[3]

The second point of importance is the presence of mistakes in the observations. The essential mistakes are classified by Schiel under two headings. Mistakes in observation are positive or negative, wrong observation or oversight. The latter occurs largely through preconceived opinions. The opponents of Copernicus concluded that the earth did not move because otherwise a stone dropped from the top of a tower would reach the ground a little to the west. If the adherents of Copernicus had made the experiment they would have discovered that the stone does fall as the theory requires. Similar oversights occur in the lawyer's work hundreds of times. We are impressed with exceptions that are made by others or by ourselves, and give up some already tried approach without actually testing the truth of the exception which challenges it. I have frequently, while at work, thought of the story of some one of the Georges, who did not like scholars and set the following problem to a number of philosophers and physicists: "When I put a ten pound stone into a hundred pound barrel of water the whole weighs a hundred and ten pounds, but when I put a live fish of ten pounds into the barrel the whole still weighs only a hundred pounds?" Each one of the scholars had his own convincing explanation, until finally the king asked one of the foot-men, who said that he would like to see the experiment tried before he made up his mind. I remember a case in which a peasant was accused of having committed arson for the sake of the insurance. He asserted that he had gone into a room with a candle and that a long spider's web which was hanging down

had caught fire from it accidentally and had inflamed the straw which hung from the roof. So the catastrophe had occurred. Only in the second examination did it occur to anybody to ask whether spider's web can burn at all, and the first experiment showed that that was impossible.

Most experiences of this kind indicate that in recognizing events we must proceed slowly, without leaping, and that we may construct our notions only on the basis of knowledge we already possess. Saint Thomas says, "Omnes cognitio fit secundum similitudinem cogniti in cognoscente." If this bit of wisdom were kept in mind in the examination of witnesses it would be an easier and simpler task than usual. Only when the unknown is connected with the known is it possible to understand the former. If it is not done the witness will hardly be able to answer. He nowhere finds support, or he seeks one of his own, and naturally finds the wrong one. So the information that an ordinary traveler brings home is mainly identical with what he carries away, for he has ears and eyes only for what he expects to see. For how long a time did the negro believe that disease pales the coral that he wears? Yet if he had only watched it he would have seen how foolish the notion was. How long, since Adam Smith, did people believe that extravagance helps industry, and how much longer have people called Copernicus a fool because they actually saw the sun rise and set. So J. S. Mill puts his opinions on this matter. Benneke[4] adds, "If anybody describes to me an animal, a region, a work of art, or narrates an event, etc., I get no notion through the words I hear of the appearance of the subject. I merely have a problem set me by means of the words and signs, in the conception of the subject, and hence it depends for truth mainly upon the completeness of earlier conceptions of similar things or events, and upon the material I have imaginatively at hand. These are my perceptual capital and my power of representation."

It naturally is not necessary to ask whether a narrator has ever seen the things he speaks of, nor to convince oneself in examination that the person in question knows accurately what he is talking about. At the same time, the examiner ought to be clear on the matter and know what attitude to take if he is going to deal intelligibly with the other. I might say that all of us, educated and uneducated, have apprehended and remember definite and distinct images of all things we have seen, heard, or learned from descriptions.

When we get new information we simply attach the new image to the old, or extinguish a part of the old and put the new in its place, or we retain only a more or less vigorous breath of the old with the new. Such images go far back; even animals possess them. One day my small son came with his exciting information that his guinea pig, well known as a stupid beast, could count. He tried to prove this by removing the six young from their mother and hiding them so that she could not see what happened to them. Then he took one of the six, hid it, and brought the remaining five back to the old lady. She smelled them one after the other and then showed a good deal of excitement, as if she missed something. Then she was again removed and the sixth pig brought back; when she was restored to her brood, she sniffed all six and showed a great deal of satisfaction. "She could count at least six." Naturally the beast had only a fixed collective image of her brood, and as one was missing the image was disturbed and incorrect. At the same time, the image was such as is created by the combination of events or circumstances. It is not far from the images of low-browed humanity and differs only in degree from those of civilized people.

The fact that a good deal of what is said is incorrect and yet not consciously untrue, depends upon the existence of these images and their association with the new material. The speaker and the auditor have different sets of images; the first relates the new material differently from a second, and so of course they can not agree.[5] It is the difficult task of the examiner so to adapt what is said as to make it appropriate to the right images without making it possible for incorrect interpretations to enter. When we have a well-known money-lender as witness concerning some unspeakable deal, a street-walker concerning some brawling in a peasant saloon, a clubman concerning a duel, a game-warden concerning poaching, the set of images of each one of these persons will be a bad foundation for new perceptions. On the other hand, it will not be difficult to abstract from them correctly. But cases of this sort are not of constant occurrence and the great trouble consists in once for all discovering what memory-images were present before the witness perceived the event in question. The former have a great influence upon the perception of the latter.

In this connection it should not be forgotten that the retention of these images is somewhat pedantic and depends upon unimportant things. In the city hall of Graz there is a secretary with thirty-six

sections for the thirty-six different papers. The name of the appropriate journal was written clearly over each section and in spite of the clearness of the script the depositing and removing of the papers required certain effort, inasmuch as the script had to be read and could not be apprehended. Later the name of the paper was cut out of each and pasted on the secretary instead of the script, and then, in spite of the various curly and twisted letters, the habitual images of the titles were easily apprehended and their removal and return became mechanical. The customary and identical things are so habitual that they are apprehended with greater ease than more distinct objects.

Inasmuch as we can conceive only on the basis of the constancy and similarity of forms, we make these forms the essence of experience. On the other hand, what is constant and similar for one individual is not so for another, and essences of experience vary with the experiencer.

"When we behold a die of which we can see three sides at a time, seven corners, and nine edges, we immediately induce the image or schema of a die, and we make our further sense-perception accord with this schema. In this way we get a series of schemes which we may substitute for one another" (Aubert). For the same reason we associate in description things unknown to the auditor, which we presuppose in him, and hence we can make him rightly understand only if we have named some appropriate object in comparison. Conversely, we have to remember that everybody takes his comparison from his own experience, so that we must have had a like experience if we are to know what is compared. It is disastrous to neglect the private nature of this experience. Whoever has much to do with peasants, who like to make use of powerful comparisons, must first comprehend their essential life, if he is to understand how to reduce their comparisons to correct meanings. And if he has done so he will find such comparisons and images the most distinct and the most intelligible.

Sense-perception has a great deal to do in apprehension and no one can determine the boundary where the sense activity ends and the intellectual begins. I do not recall who has made note of the interesting fact that not one of twenty students in an Egyptian museum knew why the hands of the figures of Egyptian was pictures gave the impression of being incorrect—nobody had observed the fact that all the figures had two right hands.

I once paid a great deal of attention to card-sharping tricks and

as I acquired them, either of myself or from practiced gamblers, I demonstrated them to the young criminalists. For a long time I refused to believe what an old Greek told me: "The more foolish and obvious a trick is, the more certain it is; people never see anything." The man was right. When I told my pupils expressly, "Now I am cheating," I was able to make with safety a false coup, a false deal, etc. Nobody saw it. If only one has half a notion of directing the eyes to some other thing, a card may be laid on the lap, thrust into the sleeve, taken from the pocket, and God knows what else. Now who can say in such a case whether the sensory glance or the intellectual apprehension was unskilful or unpractised? According to some authorities the chief source of error is the senses, but whether something must not be attributed to that mysterious, inexplicable moment in which sensory perception becomes intellectual perception, nobody can say.

My favorite demonstration of how surprisingly little people perceive is quite simple. I set a tray with a bottle of water and several glasses on the table, call express attention to what is about to occur, and pour a little water from the bottle into the glass. Then the stuff is taken away and the astonishing question asked what have I done? All the spectators reply immediately: you have poured water into a glass. Then I ask further with what hand did I do it? How many glasses were there? Where was the glass into which I poured the water? How much did I pour? How much water was there in the glass? Did I really pour or just pretend to? How full was the bottle? Was it certainly water and not, perhaps, wine? Was it not red wine? What did I do with my hand after pouring the water? How did I look when I did it? Did you not really see that I shut my eyes? Did you not really see that I stuck my tongue out? Was I pouring the water while I did it? Or before, or after? Did I wear a ring on my hand? Was my cuff visible? What was the position of my fingers while I held the glass? These questions may be multiplied. And it is as astonishing as amusing to see how little correctness there is in the answers, and how people quarrel about the answers, and what extraordinary things they say. Yet what do we require of witnesses who have to describe much more complicated matters to which their attention had not been previously called, and who have to make their answers, not immediately, but much later; and who, moreover, may, in the presence of the fact, have been overcome by fear, astonishment, terror, etc.! I find that probing even comparatively trained witnesses

is rather too funny, and the conclusions drawn from what is so learned are rather too conscienceless.[6] Such introductions as: "But you will know,"—"Just recall this one,"—"You wouldn't be so stupid as not to have observed whether,"—"But my dear woman, you have eyes,"—and whatever else may be offered in this kindly fashion, may bring out an answer, but what real worth can such an answer have?

One bright day I came home from court and saw a man step out of a cornfield, remain a few instants in my field of vision, and then disappear. I felt at once that the man had done something suspicious, and immediately asked myself how he looked. I found I knew nothing of his clothes, his dress, his beard, his size, in a word, nothing at all about him. But how I would have punished a witness who should have known just as little. We shall have, in the course of this examination, frequently to mention the fact that we do not see an event in spite of its being in the field of perception. I want at this point merely to call attention to a single well-known case, recorded by Hofmann.[7] At a trial a circumstantial and accurate attempt was made to discover whether it was a significant alteration to bite a man's ear off. The court, the physician, the witnesses, etc., dealt with the question of altering, until finally the wounded man himself showed what was meant, because his other ear had been bitten off many years before,—but then nobody had noticed that mutilated ear.

In order to know what another person has seen and apprehended we must first of all know how he thinks, and that is impossible. We frequently say of another that he must have thought this or that, or have hit upon such and such ideas, but what the events in another brain may be we can never observe. As Bois-Reymond says somewhere: "If Laplace's ghost could build a homunculus according to the Leibnitzian theory, atom by atom and molecule by molecule, he might succeed in making it think, but not in knowing how it thinks." But if we know, at least approximately, the kind of mental process of a person who is as close as possible to us in sex, age, culture, position, experience, etc., we lose this knowledge with every step that leads to differences. We know well what great influence is exercised by the multiplicity of talents, superpositions, knowledge, and apprehensions. When we consider the qualities

of things, we discover that we never apprehend them abstractly, but always concretely. We do not see color but the colored object; we do not see warmth, but something warm; not hardness, but something hard. The concept warm, as such, can not be thought of by anybody, and at the mention of the word each will think of some particular warm object; one, of his oven at home; another, of a warm day in Italy; another of a piece of hot iron which burnt him once. Then the individual does not pay constant court to the same object. To-day he has in mind this concrete thing, to-morrow, he uses different names and makes different associations. But every concrete object I think of has considerable effect on the new apprehension; and my auditor does not know, perhaps even I myself do not, what concrete object I have already in mind. And although Berkeley has already shown that color can not be thought of without space or space without color, the task of determining the concrete object to which the witness attaches the qualities he speaks of, will still be overlooked hundreds of times.

It is further of importance that everybody has learned to know the object he speaks about through repetition, that different relations have shown him the matter in different ways. If an object has impressed itself upon us, once pleasurably and once unpleasantly, we can not derive the history and character of the present impression from the object alone, nor can we find it merely in the synthetic memory sensations which are due to the traces of the former coalescing impressions. We are frequently unable, because of this coalescing of earlier impressions, to keep them apart and to study their effect on present impressions. Frequently we do not even at all know why this or that impression is so vivid. But if we are ignorant with regard to what occurs in ourselves, how much can we know about others?

Exner calls attention to the fact that it is in this direction especially, that the "dark perceptions" play a great rôle. "A great part of our intelligence depends on the ability of these `dark perceptions' to rise without requiring further attention, into the field of consciousness. There are people, e. g., who recognize birds in their flight without knowing clearly what the characteristic flight for any definite bird may be. Others, still more intelligent, know at what intervals the flyers beat their wings, for they can imitate them with their hands. And when the intelligence is still greater, it makes possible a correct description in words."

Suppose that in some important criminal case several people,

of different degrees of education and intelligence, have made observations. We suppose that they all want to tell the truth, and we also suppose that they have observed and apprehended their objects correctly. Their testimonies, nevertheless, will be very different. With the degree of intelligence rises the degree of effect of the "dark subconscious perceptions." They give more definite presentation and explanation of the testimony; they turn bare assertions into well-ordered perceptions and real representations. But we generally make the mistake of ascribing the variety of evidence to varying views, or to dishonesty.

To establish the unanimity of such various data, or to find out whether they have such unanimity, is not easy. The most comfortable procedure is to compare the lesser testimonies with those of the most intelligent of the witnesses. As a rule, anybody who has a subconscious perception of the object will be glad to bring it out if he is helped by some form of expression, but the danger of suggestion is here so great that this assistance must be given only in the rarest of cases. The best thing is to help the witness to his full evidence gradually, at the same time taking care not to suggest oneself and thus to cause agreement of several testimonies which were really different but only appeared to look contradictory on account of the effect of subconscious perceptions. The very best thing is to take the testimony as it comes, without alteration, and later on, when there is a great deal of material and the matter has grown clearer, to test the stuff carefully and to see whether the less intelligent persons gave different testimonies through lack of capacity in expression, or because they really had perceived different things and had different things to say.

This is important when the witnesses examined are experts in the matter in which they are examined. I am convinced that the belief that such people must be the best witnesses, is false, at least as a generalization. Benneke (loco cit.), has also made similar observations. "The chemist who perceives a chemical process, the connoisseur a picture, the musician a symphony, perceive them with more vigorous attention than the layman, but the actual attention may be greater with the latter." For our own affair, it is enough to know that the judgment of the expert will naturally be better than that of the layman; his apprehension, however, is as a rule one-sided, not so far-reaching and less uncolored. It is natural that every expert, especially when he takes his work seriously, should find most interest in that side of an event with which his

profession deals. Oversight of legally important matters is, therefore, almost inevitable. I remember how an eager young doctor was once witness of an assault with intent to kill. He had seen how in an inn the criminal had for some time threatened his victim with a heavy porcelain match-tray. "The os parietale may here be broken," the doctor thought, and while he was thinking of the surgical consequences of such a blow, the thing was done and the doctor had not seen how the blow was delivered, whether a knife had been drawn by the victim, etc. Similarly, during an examination concerning breaking open the drawer of a table, the worst witness was the cabinet-maker. The latter was so much interested in the foreign manner in which the portions of the drawer had been cemented and in the curious wood, that he had nothing to say about the legally important question of how the break was made, what the impression of the damaging tool was, etc. Most of us have had such experiences with expert witnesses, and most of us have also observed that they often give false evidence because they treat the event in terms of their own interest and are convinced that things must happen according to the principles of their trades. However the event shapes itself, they model it and alter it so much that it finally implies their own apprehension.

"Subconscious perceptions," somewhat altered, play another rôle, according to Exner, in so-called orientation. If anybody is able to orient himself, i. e., know where he is at any time and keep in mind the general direction, it is important to be aware of the fact when he serves as witness, for his information will, in consequence, take a different form and assume a different value. Exner says of himself, that he knows at each moment of his climb of the Marcus' tower in what direction he goes. As for me, once I have turned around, I am lost. Our perceptions of location and their value would be very different if we had to testify concerning relations of places, in court. But hardly anybody will assure the court that in general he orients himself well or ill.

As Exner says, "If, when walking, I suddenly stop in front of a house to look at it, I am definitely in possession, also, of the feeling of its distance from where I left the road—the unconscious perception of the road beyond is here at work." It might, indeed, be compared with pure subconsciousness in which series of processes occur without our knowing it.

But local orientation does not end with the feeling for place. It is at work even in the cases of small memories of location, e. g.,

in learning things by heart, in knowing on what page and on what line anything is printed, in finding unobserved things, etc. These questions of perception-orientation are important, for there are people all of whose perceptions are closely related to their sense of location. Much may be learned from such people by use of this specialty of theirs, while oversight thereof may render them hopeless as witnesses. How far this goes with some people—as a rule people with a sense of location are the more intelligent—I saw some time ago when the Germanist Bernhardt Seuffert told me that when he did not know how anything is spelled he imagined its appearance, and when that did not help he wrote both the forms between which he was vacillating and then knew which one was the correct one. When I asked him whether the chirographic image appeared printed or written and in what type, he replied significantly enough, "As my writing-teacher wrote it." He definitely localized the image on his writing book of many years ago and read it off in his mind. Such specialties must be remembered in examining witnesses.

In conclusion, there is a word to say concerning Cattell's[8] investigations of the time required for apprehension. The better a man knows the language the more rapidly can he repeat and read its words. It is for this reason that we believe that foreigners speak more rapidly than we. Cattell finds this so indubitable, that he wants to use speed as a test in the examinations in foreign languages.

The time used in order to identify a single letter is a quarter of a second, the time to pronounce it one-tenth of a second. Colors and pictures require noticeably more, not because they are not recognized, but because it is necessary to think what the right name is. We are much more accustomed to reading words.

These observations might be carried a step further. The more definitely an event to be described is conceived, the clearer the deduction and the more certain the memory of it, the more rapidly may it be reproduced. It follows that, setting aside individual idiosyncrasies, the rapidity of speech of a witness will be of importance when we want to know how much he has thought on a question and is certain what he is going to say. It is conceivable that a person who is trying to remember the event accurately will speak slowly and stutteringly, or at least with hesitation at the moment. The same will occur if he tries to conceive of various

possibilities, to eliminate some, and to avoid contradiction and improbability. If, however, the witness is convinced and believes truly what he is telling, so that he may go over it in his mind easily and without interruption, he will tell his story as quickly as he can. This may indeed be observed in public speakers, even judges, prosecutors, and defense; if anyone of them is not clear with regard to the case he represents, or not convinced of its correctness, he will speak slowly; if the situation is reversed he will speak rapidly. Court and other public stenographers confirm this observation.

The things witnesses tell us have formerly existed in their imaginations, and the how of this existence determines in a large degree the quale of what they offer us. Hence, the nature of imagination must be of interest to us, and the more so, as we need not concern ourselves with the relation between being and imagination. It may be that things may exist in forms quite different from those in which we know them, perhaps even in unknowable forms. The idealist, according to some authorities, has set this possibility aside and given a scientific reply to those who raised it.

So far as we lawyers are concerned, the "scientific reply" does not matter. We are interested in the reliability of the imagination and in its identification with what we assume to exist and to occur. Some writers hold that sensory objects are in sense-perception both external and internal, external with regard to each other, and internal with regard to consciousness. Attention is called to the fact that the distinction between image and object constitutes no part of the act of perception. But those who remark this fact assume that the act does contain an image. According to St. Augustine the image serves as the knowledge of the object; according to Erdmann the object is the image objectified.

Of great importance is the substitutional adequacy of images. E. g., I imagine my absent dog, Bismarck's dog, whom I know only pictorially, and finally, the dog of Alcibiades, whose appearance is known only by the fact that he was pretty and that his master had cut off his tail. In this case, the representative value of these images will be definite, for everybody knows that I can imagine my own dog very correctly, that the image of Bismarck's beast will also be comparatively good inasmuch as this animal has been frequently

pictured and described, while the image of Alcibiades' dog will want much in the way of reliability—although I have imagined this historic animal quite vividly since boyhood. When, therefore, I speak of any one of these three animals everybody will be able properly to value the correctness of my images because he knows their conditions. When we speak with a witness, however, we rarely know the conditions under which he has obtained his images, and we learn them only from him. Now it happens that the description offered by the witness adds another image, i. e., our own image of the matter, and this, and that of the witness, have to be placed in specific relation to each other. Out of the individual images of all concerned an image should be provided which implies the image of the represented event. Images can be compared only with images, or images are only pictures of images.[1]

The difficulty of this transmutation lies fundamentally in the nature of representation. Representation can never be identical with its object. Helmholtz has made this most clear: "Our visions and representations are effects; objects seen and represented have worked on our nervous system and on our consciousness. The nature of each effect depends necessarily upon the nature of its cause, and the nature of the individual upon whom the cause was at work. To demand an image which should absolutely reproduce its object and therefore be absolutely true, would be to demand an effect which should be absolutely independent of the nature of that object on which the effect is caused. And this is an obvious contradiction."

What the difference between image and object consists of, whether it is merely formal or material, how much it matters, has not yet been scientifically proved and may never be so. We have to assume only that the validity of this distinction is universally known, and that everybody possesses an innate corrective with which he assigns proper place to image and object, i. e., he knows approximately the distinction between them. The difficulty lies in the fact that not all people possess an identical standard, and that upon the creation of the latter practically all human qualities exert an influence. This variety in standards, again, is double-edged. On the one side it depends on the essence of image and of object, on the other it depends on the alteration which the image undergoes even during perception as well as during all the ensuing time. Everybody knows this distinction. Whoever has seen anything under certain circumstances, or during a certain period of his life, may frequently

produce an image of it varying in individual characteristics, but in its general character constant. If he sees it later under different conditions, at a different age, when memory and imaginative disposition have exercised their alterative influence, image and object fail to correspond in various directions. The matter is still worse with regard to images of things and events that have never been seen. I can imagine the siege of Troy, a dragon, the polar night and Alexander the Great, but how different will the image be from the object!

This is especially obvious when we have perceived something which did not appear to us altogether correct. We improve the thing, i. e., we study how it might have been better, and we remember it as improved; then the more frequently this object as imagined recurs, the more fixed its form becomes, but not its actual form, only its altered form. We see this with especial clearness in the case of drawings that in some way displease us. Suppose I do not like the red dress of a woman in some picture and I prefer brown. If later I recall the picture the image will become progressively browner and browner, and finally I see the picture as brown, and when I meet the real object I wonder about the red dress.[2]

We get this situation in miniature each time we hear of a crime, however barren the news may be,—no more than a telegraphic word. The event must naturally have some degree of importance, because, if I hear merely that a silver watch has been stolen, I do not try to imagine that situation. If, however, I hear that near a hostelry in X, a peasant was robbed by two traveling apprentices I immediately get an image which contains not only the unknown region, but also the event of the robbery, and even perhaps the faces of those concerned. It does not much matter that this image is completely false in practically every detail, because in the greater number of cases it is corrected. The real danger lies in the fact that this correction is frequently so bad and often fails altogether and that, in consequence, the first image again breaks through and remains the most vigorous.[3] The vigor is the greater because we always attach such imagination to something actual or approximately real, and inasmuch as the latter thing is either really seen, or at least energetically imagined, the first image acquires renewed power of coming up. According to Lipps, "Reproductive images

presuppose dispositions. Dispositions ensue upon perceptions that they imply; still there are reproductive images and imagined wholes which imply no preceding perceptions. This contradiction is solved when dispositions are contained in other things at the same time. A finite number of dispositions may in this way be also infinite.... Dispositions are transformed power itself, power transformed in such a way as to be able to respond actively to inner stimulations."

The process is similar in the reproduction of images during speech. The fact that this reproduction is not direct but depends on the sequence of images, leads to the garrulity of children, old men, and uneducated people, who try to present the whole complex of relations belonging to any given image. But such total recall drives the judge to despair, not only because he loses time, but because of the danger of having the attention turned from important to unimportant things. The same thing is perceived in judicial documents which often reveal the fact that the dictator permitted himself to be led astray by unskilful witnesses, or that he had himself been responsible for abstruse, indirect memories. The real thinker will almost always be chary of words, because he retains, from among the numberless images which are attached to his idea, only those most closely related to his immediate purpose. Hence good protocols are almost always comparatively short. It is even as instructive as amusing to examine certain protocols, with regard to what ought to be omitted, and then with regard to the direct representations, i. e., to everything that appertains to the real illumination of the question. It is astounding how little of the latter thing is indicated, and how often it enters blindly because what was important has been forgotten and lost.

Of course, we must grant that the essence of representation involves very great difficulties. By way of example consider so ordinary a case as the third dimension. We are convinced that according to its nature it is much more complex than it seems to be. We are compelled to believe that distance is not a matter of sensation and that it requires to be explained.[4]

Psychologists indicate that the representation of the third dimension would be tremendously difficult without the help of experience. But experience is something relative, we do not know how much experience any man possesses, or its nature. Hence, we never can know clearly to what degree a man's physical vision is correct if

we do not see other means of verification. Consider now what is required in the assumption of the idea of the fourth dimension. Since its introduction by Henry More, this idea should quite have altered our conception of space. But we do not know how many cling to it unconsciously, and we should make no mistake if we said that nobody has any knowledge of how his neighbor perceives space.[5]

Movement is another thing difficult to represent or imagine. You can determine for yourself immediately whether you can imagine even a slightly complicated movement. I can imagine one individual condition of a movement after another, sequentially, but I can not imagine the sequence. As Herbart says somewhere, a successive series of images is not a represented succession. But if we can not imagine this latter, what do we imagine is not what it ought to be. According to Stricker,[6] the representation of movement is a quale which can not be given in terms of any other sensory quality, and no movement can be remembered without the brain's awakening a muscle-movement. Experience verifies this theory. The awakening of the muscular sense is frequently obvious whenever movement is thought of, and we may then perceive how, in the explanation or description of a movement, the innervation which follows the image in question, occurs. This innervation is always true. It agrees at least with what the witness has himself perceived and now tries to renew in his story. When we have him explain, for example, how some man had been choked, we may see movements of his hands which, however slight and obscure, still definitely indicate that he is trying to remember what he has seen, and this irrelevantly of what he is saying. This makes it possible to observe the alterations of images in the individual in question, an alteration which always occurs when the images are related to movements.

It follows further from the fact that movements are difficult to represent that the witness ought not to be expected accurately to recall them. Stricker says that for a long time he could not image a snow-fall, and succeeded only in representing one single instant of it. Now what is not capable of representation, can not well be recalled, and so we discover that it merely causes trouble to ask the witness to describe point by point even a simple sequence. The witness has only successive images, and even if the particular images are correct,

he has nothing objective for the succession itself, nothing rooted in the sequence. He is helped, merely, by the logic of events and his memory—if these are scanty, the succession of images is scanty, and therefore the reproduction of the event is inadequate. Hence this scantiness is as little remarkable as the variety of description in various witnesses, a variety due to the fact that the sequentialization is subjective.

Drawing is a confirmation of the fact that we represent only a single instant of motion, for a picture can never give us a movement, but only a single state within that movement. At the same time we are content with what the picture renders, even when our image contains only this simple moment of movement. "What is seen or heard, is immediately, in all its definiteness, content of consciousness" (Schuppe)—but its movement is not.

The influence of time upon images is hardly indifferent. We have to distinguish the time necessary for the construction of an image, and the time during which an image lasts with uniform vividness. Maudsley believes the first question difficult to answer. He leans on Darwin, who points out that musicians play as quickly as they can apprehend the notes. The question will affect the lawyer in so far as it is necessary to determine whether, after some time, an image of an event may ensue from which it is possible to infer back to the individuality of the witness. No other example can be used here, because on the rocky problem of the occurrence of images are shattered even the regulative arts of most modern psychophysics.

The second problem is of greater significance. Whether any practical use of its solution can be made, I can not say, but it urges consideration. Exner has observed that the uniform vividness of an image lasts hardly a second. The image as a whole does not disappear in this time, but its content endures unchanged for so long at most. Then it fades in waves. The correctness of this description may be tested by anybody. But I should like to add that my observations of my own images indicate that in the course of a progressive repetition of the recall of an image its content is not equally capable of reproduction. I believe, further, that no essential leaps occur in this alteration of the content of an idea, but that the alteration moves in some definite direction. If, then, I recall the idea of some object successively, I will imagine it not at one time bigger, then smaller, then again bigger, etc.; on the contrary, the series of images will be such that each new image will be either progressively bigger or progressively smaller.

If this observation of mine is correct and the phenomenon is not purely personal, Exner's description becomes of great value in examination, which because of its length, requires the repeated recall of standardizing images, and this in its turn causes an alteration in the ideational content. We frequently observe that a witness persuades himself into the belief of some definite idea in the course of his examination, inasmuch as with regard to some matter he says more and more definite things at the end than at the beginning. This may possibly be contingent on the alteration of frequently recalled ideas. One could make use of the process which is involved in the reproduction of the idea, by implying it, and so not being compelled to return endlessly to something already explained.

How other people construct their ideas, we do not, as we have seen, know, and the difficulty of apprehending the ideas or images of other people, many authorities clearly indicate.[7]

Topic 4. INTELLECTUAL PROCESSES.

Section 46. (a) General Considerations.

Lichtenberg said somewhere, "I used to know people of great scholarship, in whose head the most important propositions were folded up in excellent order. But I don't know what occurred there, whether the ideas were all mannikins or all little women— there were no results. In one corner of the head, these gentlemen put away saltpeter, in another sulphur, in a third charcoal, but these did not combine into gunpowder. Then again, there are people in whose heads everything seeks out and finds everything else, everything pairs off with everything else, and arranges itself variously." What Lichtenberg is trying to do is to indicate that the cause of the happy condition of the last-named friends is imagination. That imagination is influential, is certain, but it is equally certain that the human understanding is so different with different people as to permit such phenomena as Lichtenberg describes. I do not want to discuss the quantity of understanding. I shall deal, this time, with its quality, by means of which the variety of its uses may be explained. It would be a mistake to think of the understanding as capable of assuming different forms. If it were it would be possible to construct from the concept understanding a group of different powers whose common quality would come to us off-hand.

But with regard to understanding we may speak only of more or less and we must think of the difference in effect in terms only of the difference of the forms of its application. We see the effects of the understanding alone, not the understanding itself, and however various a burning city, cast iron, a burn, and steaming water may be, we recognize that in spite of the difference of effect, the same fire has brought about all these results. The difference in the uses of the understanding, therefore, lies in the manner of its application. Hence these applications will help us, when we know them, to judge the value of what they offer us. The first question that arises when we are dealing with an important witness who has made observations and inferences, is this: "How intelligent is he? and what use does he make of his intelligence? That is, What are his processes of reasoning?"

I heard, from an old diplomat, whose historic name is as significant as his experience, that he made use of a specific means to discover what kind of mind a person had. He used to tell his subjects the following story: "A gentleman, carrying a small peculiarly-formed casket, entered a steam car, where an obtrusive commercial traveler asked him at once what was contained in the casket. `My Mungo is inside!' `Mungo? What is that?' `Well, you know that I suffer from delirium tremens, and when I see the frightful images and figures, I let my Mungo out and he eats them up.' `But, sir, these images and figures do not really exist.' `Of course they don't really exist, but my Mungo doesn't really exist, either, so it's all right!' "

The old gentleman asserted that he could judge of the intelligence of his interlocutor by the manner in which the latter received this story.

Of course it is impossible to tell every important witness the story of Mungo, but something similar may be made use of which could be sought out of the material in the case. Whoever has anything worthy the name of practice will then be able to judge the manner of the witness's approach, and especially the degree of intelligence he possesses. The mistake must not be made, however, that this requires splendid deductions; it is best to stick to simple facts. Goethe's golden word is still true: "The greatest thing is to understand that all fact is theory . . . do not look behind phenomena; they are themselves the doctrine." We start, therefore, with some simple fact which has arisen in the case and try to discover what the witness will do with it. It is not difficult; you may know a thing badly in a hundred ways, but you know it well in only one way. If

the witness handles the fact properly, we may trust him. We learn, moreover, from this handling how far the man may be objective. His perception as witness means to him only an experience, and the human mind may not collect experiences without, at the same time, weaving its speculations into them. But though everyone does this, he does it according to his nature and nurture. There is little that is as significant as the manner, the intensity, and the direction in and with which a witness introduces his speculation into the story of his experience. Whole sweeps of human character may show themselves up with one such little explanation. It is for this reason that Kant called the human understanding architectonic; it aims to bring together all its knowledge under one single system, and this according to fixed rules and systems defined by the needs of ordinary mortals. Only the genius has, like nature, his own unknown system. And we do not need to count on this rarest of exceptions.

The people who constitute our most complicated problems are the average, and insignificant members of the human race. Hume cited the prophet Alexander quite justly. Alexander was a wise prophet, who selected Paphlagonis as the first scene of his deception because the people there were extraordinarily foolish and swallowed with pleasure the coarsest of swindles. They had heard earlier of the genuineness and power of the prophet, and the smart ones laughed at him, the fools believed and spread his faith, his cause got adherents even among educated people, and finally Marcus Aurelius himself paid the matter so much attention as to rest the success of a military enterprise on a prophecy of Alexander's. Tacitus narrates how Vespasian cured a blind man by spitting on him, and the story is repeated by Suetonius.

We must never forget that, however great a foolishness may be, there is always somebody to commit it. It is Hume, again, I think, who so excellently describes what happens when some inconceivable story is told to uncritical auditors. Their credulity increases the narrator's shamelessness; his shamelessness convinces their credulity. Thinking for yourself is a rare thing, and the more one is involved with other people in matters of importance, the more one is convinced of the rarity. And yet, so little is demanded in thinking. "To abstract the red of blood from the collective impression, to discover the same concept in different things, to bring together under the same notion blood and beer, milk and snow,—animals do not do this; it is thinking."[1] I might suggest that in the first

place, various animals are capable of something of the sort, and in the second place, that many men are incapable of the same thing. The lawyer's greatest of all mistakes is always the presupposition that whoever has done anything has also thought about doing it and while he was doing it. This is especially the case when we observe that many people repeatedly speak of the same event and drive us to the opinion that there must be some intelligent idea behind it,—but however narrow a road may be, behind it there may be any number of others in series.

We also are bound to be mistaken if we presuppose the lack of reason as a peculiarity of the uneducated only, and accept as well thought-out the statements of people who possess academic training. But not everybody who damns God is a philosopher, and neither do academic persons concern themselves unexceptionally with thinking. Concerning the failure of our studies in the high-schools and in the gymnasia, more than enough has been written, but Helmholtz, in his famous dissertation, "Concerning the Relation of the Natural Sciences to the Whole of Knowledge," has revealed the reason for the inadequacy of the material served up by gymnasia and high-schools. Helmholtz has not said that the university improves the situation only in a very small degree, but it may be understood from his words. "The pupils who pass from our grammar-schools to exact studies have two defects; 1. A certain laxity in the application of universally valid laws. The grammatical rules with which they have been trained, are as a matter of fact, buried under series of exceptions; the pupils hence are unaccustomed to trust unconditionally to the certainty of a legitimate consequence of some fixed universal law. 2. They are altogether too much inclined to depend upon authority even where they can judge for themselves."

Even if Helmholtz is right, it is important for the lawyer to recognize the distinction between the witness who has the gymnasium behind him and the educated man who has helped himself without that institution. Our time, which has invented the Ph. D., which wants to do everything for the public school and is eager to cripple the classical training in the gymnasium, has wholly forgotten that the incomparable value of the latter does not lie in the minimum of Latin and Greek which the student has acquired, but in the disciplinary intellectual drill contained in the grammar of the ancient tongues. It is superfluous to make fun of the fact that the technician writes on his visiting cards: Stud. Eng. or Stud. Mech. and can not

pronounce the words the abbreviations stand for, that he becomes Ph. D. and can not translate his title,—these are side issues. But it is forgotten that the total examination in which the public school pupil presents his hastily crammed Latin and Greek, never implies a careful training in his most impressionable period of life. Hence the criminalist repeatedly discovers that the capacity for trained thinking belongs mainly to the person who has been drilled for eight years in Greek and Latin grammar. We criminalists have much experience in this matter.

Helmholtz's first point would, for legal purposes, require very broad interpretation of the term, "universally valid laws," extending it also to laws in the judicial sense of the word. The assertion is frequently made that laws are passed in the United States in order that they might not be obeyed, and political regulations are obeyed by the public for, at most, seven weeks. Of course, the United States is no exception; it seems as if the respect for law is declining everywhere, and if this decline occurs in one field no other is likely to be free from it. A certain subjective or egoistic attitude is potent in this regard, for people in the main conceive the law to be made only for others; they themselves are exceptions. Narrow, unconditional adherence to general norms is not modern, and this fact is to be seen not only in the excuses offered, but also in the statements of witnesses, who expect others to follow prescriptions approximately, and themselves hardly at all. This fact has tremendous influence on the conceptions and constructions of people, and a failure to take it into consideration means considerable error.

Not less unimportant is the second point raised in the notion of "authority." To judge for himself is everybody's business, and should be required of everybody. Even if nobody should have the happy thought of making use of the better insight, the dependent person who always wants to go further will lead himself into doubtful situations. The three important factors, school, newspaper, and theater, have reached an extraordinary degree of power. People apperceive, think, and feel as these three teach them, and finally it becomes second nature to follow this line of least resistance, and to seek intellectual conformity. We know well enough what consequences this has in law, and each one of us can tell how witnesses present us stories which we believe to rest on their own insight but which show themselves finally to depend upon the opinion of some other element. We frequently base our constructions upon the remarkable and convincing unanimity of such witnesses when upon

closer examination we might discover that this unanimity has a single source. If we make this discovery it is fortunate, for only time and labor have then been lost and no mistake has been committed. But if the discovery is not made, the unanimity remains an important, but really an unreliable means of proof.

Section 47. (b) The Mechanism of Thinking.

Since the remarkable dissertation of W. Ostwald,[1] on Sept. 20, 1905, we have been standing at a turning point which looks toward a new view of the world. We do not know whether the "ignorabimus" of some of the scientists will hold, or whether we shall be able to think everything in terms of energy. We merely observe that the supposedly invincible principles of scientific materialism are shaken.

Frederick the Great, in a letter to Voltaire, says something which suggests he was the first to have thought of the purely mechanical nature of thought. Cabanis had said briefly, that the brain secretes thought as the liver bile. Tyndall expressed this conception more cautiously, and demanded merely the confession that every act of consciousness implies a definite molecular condition of the brain, while Bois-Reymond declared that we could not explain certain psychical processes and events by knowledge of the material processes in the brain. "You shall make no picture or comparison, but see as directly as the nature of our spirit will permit," Ostwald tells us, and it is well to stick to this advice. We need neither to cast aside the mechanical view of the world nor to accept energism; neither of them is required. But according to the teachings of the latter, we shall be enabled to recognize the meaning of natural law in the determination of how actual events are conditioned by possible ones. And thus we shall see that the form that all natural laws turn to expresses the mediation of an invariable, a quantity that remains unchangeable even when all the other elements in the formula of a possible event alter within the limits defined by the law.[2]

Every science must provide its own philosophy, and it is our duty to know properly and to understand clearly how far we may perceive connections between the physical qualities of any one of our witnesses and his psychic nature. We will draw no inferences ourselves, but we will take note of what does not explain itself and apply

to experts to explain what we can not. This is especially necessary where the relation of the normal to the abnormal becomes a question.

The normal effects to be spoken of are very numerous, but we shall consider only a few. The first is the connection of symbol and symbolized. "The circumstance that the symbol, on its side of the union of the two, becomes perfectly clear while the symbolized object is rather confused, is explained by the fact that the symbol recalls its object more quickly than the object the symbol; e.g., the tool recalls its use more quickly than the purpose its instrument. Name and word recall more quickly, reliably, and energetically the objects they stand for than do the objects their symbols."[3] This matter is more important than it looks at first glance, inasmuch as the particles of time with which we are dealing are greater than those with which modern psychologists have to deal,—so large indeed, that they may be perceived in practice. We lay stress during the examination, when we are in doubt about the correctness of the expected answer, upon the promptness and rapidity with which it is given. Drawn out, tentative, and uncertain answers, we take for a sign that the witness either is unable or unwilling to give his replies honestly. If, however, psychologically there are real reasons for variation in the time in which an answer is given, reasons which do not depend on its correctness, we must seek out this correctness. Suppose that we have before us a case in which the name awakens more quickly and reliably the idea of the person to whom it belongs than conversely. This occurs to any one of us, and often we can not remember the name of even a close friend for a greater or shorter period. But we very rarely find that we do not think of the appearance of the individual whose name we hear mentioned. But it would be wrong to relate this phenomenon to certain qualities which contradict it only apparently. E. g., when I examine old statutes which I myself have worked with and review the names of the series, I recall that I had something to do with this Jones, Smith, Black, or White, and I recall what the business was, but I do not recall their appearance. The reason is, first of all, the fact that during the trial I did not care about the names which served as a means of distinguishing one from the other, and they might, for that purpose, have been a, b, c, etc. Hence, the faces and names were not as definitely associated as they ordinarily are. Moreover, this failure to recall is a substitution for each other of the many tanti quanti that we take up in our daily routine. When we have

had especial business with any particular individual we do remember his face when his name is mentioned.

If, then, a witness does not quickly recall the name of something he is thinking of, but identifies it immediately when the name is given him, you have a natural psychological event which itself has no bearing on the truth or falsity of his testimony.

The same relation is naturally to be found in all cases of parallel phenomena, i. e., names, symbols, definitions, etc. It applies, also, to the problem of the alteration in the rapidity of psychical processes with the time of the day. According to Bechterew and Higier there is an increase in psychical capacity from morning to noon, then a dropping until five o'clock in the afternoon, then an increase until nine o'clock in the evening, and finally a sinking until twelve o'clock midnight. There is, of course, no doubt that these investigators have correctly collected their material; that their results shall possess general validity is, however, not so certain. The facts are such that much depends, not only on the individual character, but also on the instant of examination. One hears various assertions of individuals at times when they are most quick to apprehend and at their best, and hence it is hardly possible to draw a general rule from such phenomena. One may be wide awake in the morning, another in the forenoon, a third at night, and at each time other people may be at their worst. In a similar fashion, the psychic disposition varies not only during the day, but from day to day. So far as my observations go the only thing uncontradicted is the fact that the period between noon and five o'clock in the afternoon is not a favorable one. I do not believe, however, that it would be correct to say that the few hours after the noon dinner are the worst in the day, for people who eat their dinners at about four or five o'clock assure me that from one to five in the afternoon, they cannot work so well. These facts may have a value for us in so far as we can succeed in avoiding the trial of important cases which require especial consideration during the time mentioned.

Section 48. (c) The Subconscious.

It is my opinion that the importance of unconscious operations[1] in legal procedure is undervalued. We could establish much that is significant concerning an individual whose unconscious doings we knew. For, as a rule, we perform unconsciously things that

are deeply habitual, therefore, first of all what everybody does— walk, greet your neighbor, dodge, eat, etc.; secondly, we perform unconsciously things to which we have become accustomed in accordance with our especial characters.[2] When, during my work, I rise, get a glass of water, drink it, and set the glass aside again, without having the slightest suspicion of having done so, I must agree that this was possible only in my well-known residence and environment, and that it was possible to nobody else, not so familiar. The coachman, perhaps, puts the horses into the stable, rubs them down, etc., and thinks of something else while doing so. He has performed unconsciously what another could not. It might happen that I roll a cigarette while I am working, and put it aside; after awhile I roll a second and a third, and sometimes I have four cigarettes side by side. I needed to smoke, had prepared a cigarette, and simply because I had to use my hands in writing, etc., I laid the cigarette aside. In consequence, the need to smoke was not satisfied and the process was repeated. This indicates what complicated things may be unconsciously performed if only the conditions are well-known; but it also indicates what the limits of unconscious action are: e. g., I had not forgotten what would satisfy my need to smoke, nor where my cigarette paper was, nor how to make a cigarette, but I had forgotten that I had made a cigarette without having smoked it. The activities first named have been repeated thousands of times, while the last had only just been performed and therefore had not become mechanical.[3]

Lipps calls attention to another instance: "It may be that I am capable of retaining every word of a speech and of observing at the same time the expression which accompanies the speech. I might be equally able to trace a noise which occurs on the street and still to pay sufficient attention to the speech. On the other hand, I should lose the thread of the speech if I were required at the same time to think of the play of feature and the noise. Expressed in general terms, idea A may possibly get on with idea B and even idea C; but B and C together make A impossible. This clearly indicates that B and C in themselves have opposed A and inhibited it in some degree, but that only the summation of their inhibition could serve really to exclude A." This is certainly correct and may perhaps be more frequently made use of when it is necessary to judge how much an individual would have done at one and the

same time, and how much he would have done unconsciously. An approximation of the possibilities can always be made.

Such complicated processes go down to the simplest operations. Aubert indicates, for example, that in riding a horse at gallop you jump and only later observe whether you have jumped to the right or the left. And the physician Forster told Aubert that his patients often did not know how to look toward right or left. At the same time, everybody remembers how when he is doing it unconsciously, and it may often be observed that people have to make the sign of the cross, or the gesture of eating in order to discover what is right and what left, although they are unconsciously quite certain of these directions. Still broader activities are bound up with this unconscious psychosis, activities for us of importance when the accused later give us different and better explanations than at the beginning, and when they have not had the opportunity to study the case out and make additional discoveries, or to think it over in the mean time. They then say honestly that the new, really probable exposition has suddenly occurred to them. As a rule we do not believe such statements, and we are wrong, for even when this sudden vision appears improbable and not easily realizable, the witnesses have explained it in this way only because they do not know the psychological process, which, as a matter of fact, consisted of subconscious thinking.

The brain does not merely receive impressions unconsciously, it registers them without the co-operation of consciousness, works them over unconsciously, awakens the latent residue without the help of consciousness, and reacts like an organ endowed with organic life toward the inner stimuli which it receives from other parts of the body. That this also influences the activity of the imagination, Goethe has indicated in his statement to Schiller: "Impressions must work silently in me for a very long time before they show them selves willing to be used poetically."

In other respects everybody knows something about this unconscious intellectual activity. Frequently we plague ourselves with the attempt to bring order into the flow of ideas—and we fail. Then the next time, without our having thought of the matter in the interval, we find everything smooth and clear. It is on this fact that the various popular maxims rest, e. g., to think a thing over, or to sleep on it, etc. The unconscious activity of thought has a great share in what has been thought out.

A very distinctive rôle belongs to the coincidence of conscious

attention with unconscious. An explanation of this process will help us, perhaps, to explain many incomprehensible and improbable things. "Even the unconscious psychic activities,—going up and down, smoking, playing with the hands, etc. conversation,— compete with the conscious or with other unconscious activities for psychic energy. Hence, a suddenly-appearing important idea may lead us to stop walking, to remain without a rule of action, may make the smoker drop his smoking, etc." The explanation is as follows: I possess, let us say, 100 units of psychic energy which I might use in attention. Now we find it difficult to attend for twenty seconds to one point, and more so to direct our thought-energy to one thing. Hence I apply only, let us say, 90 units to the object in question, and apply 10 units to the unconscious play of ideas, etc. Now, if the first object suddenly demands even more attention, it draws off the other ten units, and I must stop playing, for absolutely without attention, even unconscious attention, nothing can be done.

This very frequent and well-known phenomenon, shows us, first of all, the unconscious activities in their agreement with the conscious, inasmuch as we behave in the same way when both are interrupted by the demand of another thing on our attention. If a row suddenly breaks out before my window I will interrupt an unconscious drumming with the fingers as well as a conscious reading, so that it would be impossible to draw any conclusion concerning the nature of these activities from the mere interruption or the manner of that interruption. This similarity is an additional ground for the fact that what is done unconsciously may be very complex. No absolute boundary may be drawn, and hence we can derive no proof of the incorrectness of an assertion from the performance itself, i. e., from what has been done unconsciously. Only human nature, its habits, idiosyncrasies, and its contemporary environment can give us any norm.

Section 49. (d) Subjective Conditions.

We have already seen that our ideation has the self for center and point of reference. And we shall later see that the kind of thinking which exclusively relates all events to itself, or the closest relations of the self, is, according to Erdmann, the essence of stupidity. There is, however, a series of intellectual processes in which the thinker pushes his self into the foreground with more or less

justification, judging everything else and studying everything else in the light of it, presupposing in others what he finds in himself, and exhibiting a greater interest in himself than may be his proper share. Such ideations are frequently to be found in high-minded natures. I know a genial high-school teacher, the first in his profession, who is so deeply absorbed in his thinking, that he never carries money, watch, or keys because he forgets and loses them. When in the examination of some critical case he needs a coin he turns to his auditors with the question: "Perhaps one of you gentlemen may by some chance have a quarter with you?" He judges from his habit of not carrying money with him, that to carry it is to be presupposed as a "perhaps," and the appearance of a quarter in this crowded auditorium must be "by chance."

The same thing is true with some of the most habitual processes of some of the most ordinary people. If a man sees a directory in which his name must be mentioned, he looks it up and studies it. If he sees a group photograph in which he also occurs he looks up his own picture, and when the most miserable cheater who is traveling under a false name picks that out, he will seek it out of his own relationships, will either alter his real name or slightly vary the maiden name of his mother, or deduce it from his place of birth, or simply make use of his christian name. But he will not be likely to move far from his precious self.

That similar things are true for readers, Goethe told us when he showed us that everything that anybody reads interests him only when he finds himself or his activities therein. So Goethe explains that business men and men of the world apprehend a scientific dissertation better than the really learned, "who habitually hear no more of it than what they have learned or taught and with which they meet their equals."

It is properly indicated that every language has the largest number of terms for those things which are most important to those who speak it. Thus we are told that the Arabians have as many as 6000 words for camel, 2000 for horse, and 50 for lion. Richness of form and use always belong together, as is shown in the fact that the auxiliaries and those verbs most often used are everywhere the most irregular This fact may be very important in examinations, for definite inferences concerning the nature and affairs of the witness may be drawn from the manner and frequency with which he uses words, and whether he possesses an especially large number of forms in any particular direction.

The fact is that we make our conceptions in accordance with the things as we have seen them, and so completely persuade ourselves of the truth of one definite, partial definition, that sometimes we wonder at a phenomenon without judging that it might have been expected to be otherwise. When I first became a student at Strassbourg, I wondered, subconsciously, when I heard the ragged gamins talk French fluently. I knew, indeed, that it was their mother-tongue, but I was so accustomed to viewing all French as a sign of higher education that this knowledge in the gamins made me marvel. When I was a child I once had to bid my grandfather adieu very early, while he was still in bed. I still recall the vivid astonishment of my perception that grandfather awoke without his habitual spectacles upon his nose. I must have known that spectacles are as superfluous as uncomfortable and dangerous when one is sleeping, and I should not even with most cursory thinking have supposed that he would have worn his spectacles during the night. But as I was accustomed always to see my grandfather with spectacles, when he did not have them I wondered at it.

Such instances are of especial importance when the judge is himself making observations, i. e., examining the premises of the crime, studying corpora delicti, etc., because we often suppose ourselves to see extraordinary and illegal things simply because we have been habituated to seeing things otherwise. We even construct and name according to this habit. Taine narrates the instructive story of a little girl who wore a medal around her throat, of which she was told, "C'est le bon Dieu." When the child once saw her uncle with a lorgnon around his neck she said, "C'est le bon Dieu de mon oncle." And since I heard the story, I have repeatedly had the opportunity to think, "C'est aussi le bon Dieu de cet homme." A single word which indicates how a man denotes a thing defines for us his nature, his character, and his circumstances.

For the same reason that everything interests us more according to the degree it involves us personally, we do not examine facts and completely overlook them though they are later shown to be unshakable, without our being able to explain their causal nexus. If, however, we know causes and relationships, these facts become portions of our habitual mental equipment. Any practitioner knows how true this is, and how especially visible during the examination of witnesses, who ignore facts which to us seem, in the nature of the case, important and definitive. In such cases we must first of all not assume that these facts have not occurred

because the witness has not explained them or has overlooked them; we must proceed as suggested in order to validate the relevant circumstances by means of the witness—i. e., we must teach him the conditions and relationships until they become portions of his habitual mental machinery. I do not assert that this is easy— on the contrary, I say that whoever is able to do this is the most effective of examiners, and shows again that the witness is no more than an instrument which is valueless in the hands of the bounder, but which can accomplish all sorts of things in the hands of the master.

One must beware, however, of too free use of the most comfortable means,—that of examples. When Newton said, "In addiscendis scientiis exempla plus prosunt, quam praecepta," he was not addressing criminalists, but he might have been. As might, also, Kant, when he proved that thinking in examples is dangerous because it allows the use of real thinking, for which it is not a substitute, to lapse. That this fact is one reason for the danger of examples is certain, but the chief reason, at least for the lawyer, is the fact that an example requires not equality, but mere similarity. The degree of similarity is not expressed and the auditor has no standard for the degree of similarity in the mind of the speaker. "Omnis analogia claudicat" is correct, and it may happen that the example might be falsely conceived, that similarity may be mistaken for equality, or at least, that there should be ignorance of the inequality. Examples, therefore, are to be used only in the most extreme cases, and only in such wise, that the nature of the example is made very clearly obvious and its incorrectness warned against.

There are several special conditions, not to be overlooked. One of these is the influence of expectation. Whoever expects anything, sees, hears, and constructs, only in the suspense of this expectation, and neglects all competing events most astoundingly. Whoever keenly expects any person is sensible only of the creaking of the garden door, he is interested in all sounds which resemble it, and which he can immediately distinguish with quite abnormal acuteness; everything else so disappears that even powerful sounds, at any event more powerful than that of the creaking gate, are overlooked. This may afford some explanation for the very different statements we often receive from numerous observers of the same event; each one had expected a different thing, and hence, had perceived and had ignored different things.

Again, the opposition of the I and You in the person himself is a noteworthy thing. According to Noel, this is done particularly when one perceives one's own foolish management: "How could you have behaved so foolishly!" Generalized it might be restated as the fact that people say You to themselves whenever the dual nature of the ego becomes visible, i. e., whenever one no longer entertains a former opinion, or when one is undecided and carries about contradictory intentions, or whenever one wants to compel himself to some achievement. Hence "How could you have done this?"—"Should you do this or should you not?"—"You simply shall tell the truth."—More naïve people often report such inner dialogues faithfully and without considering that they give themselves away thereby, inasmuch as the judge learns at least that when this occurred the practical ego was a stranger to the considering ego, through whom the subjective conditions of the circumstances involved may be explained.

What people call excellent characterizes them. Excellences are for each man those qualities from which others get the most advantage. Charity, self-sacrifice, mercy, honesty, integrity, courage, prudence, assiduity, and however else anything that is good and brave may be called, are always of use to the other fellow but barely and only indirectly the possessor of the virtues. Hence we praise the latter and spur others on to identical qualities (to our advantage). This is very barren and prosaic, but true. Naturally, not everybody has advantage in the identical virtues of other people, only in those which are of use to their individual situation— charity is of no use to the rich, and courage of no use to the protected. Hence, people give themselves away more frequently than they seem to, and even when no revelation of their inner lives can be attained from witnesses and accused, they always express enough to show what they consider to be virtue and what not.

Hartenstein characterizes Hegel as a person who made his opponents out of straw and rags in order to be able to beat them down the more easily. This characterizes not only Hegel but a large group of individuals whose daily life consists of it. Just as there is nowhere any particularly definite boundary between sanity and foolishness, and everything flows into everything else, so it is with men and their testimonies, normal and abnormal. From the sober, clear, and true testimony of the former, to the fanciful and impossible assertions of the latter, there is a straight, slowly rising road on which testimony appears progressively less true, and more impossible.

No man can say where the quality of foolishness begins—nervousness, excitement, hysteria, over-strain, illusion, fantasy, and pathoformic lies, are the shadings which may be distinguished, and the quantity of untruth in such testimonies may be demonstrated, from one to one hundred per cent., without needing to skip a single degree. We must not, however, ignore and simply set aside even the testimony of the outlaws and doubtful persons, because also they may contain some truth, and we must pay still more attention to such as contain a larger percentage of truth. But with this regard we have our so-called smart lawyers who are over-strained, and it is they who build the real men of straw which cost us so much effort and labor. The form is indeed correct, but the content is straw, and the figure appears subjectively dangerous only to its creator. And he has created it because he likes to fight but desires also to conquer easily. The desire to construct such figures and to present them to the authorities is widespread and dangerous through our habit of seeking some particular motive, hatred, jealousy, a long-drawn quarrel, revenge, etc. If we do not find it we assume that such a motive is absent and take the accusation, at least for the time, to be true. We must not forget that frequently there can be no other defining motive than the desire to construct a man of straw and to conquer him. If this explanation does not serve we may make use finally of a curious phenomenon, called by Lazarus heroification, which repeats itself at various levels of life in rather younger people. If we take this concept in its widest application we will classify under it all forms that contain the almost invincible demand for attention, for talking about oneself, for growing famous, on the part of people who have neither the capacity nor the perseverance to accomplish any extraordinary thing, and who, hence, make use of forbidden and even criminal means to shove their personalities into the foreground and so to attain their end. To this class belong all those half-grown girls who accuse men of seduction and rape. They aim by this means to make themselves interesting. So do the women who announce all kinds of persecutions which make them talked about and condoled with; and the numerous people who want to do something remarkable and commit arson; then again certain political criminals of all times who became "immortal" with one single stab, and hence devoted their otherwise worthless lives thereto; and finally, even all those who, when having suffered from some theft, arson, or bodily harm, defined their damage as considerably greater than it actually was, not for the purpose of recovering their losses, but for the purpose of being discussed and condoled with.

As a rule it is not difficult to recognize this "heroification," inasmuch as it betrays itself through the lack of other motives, and appears definitely when the intent is examined and exaggerations are discovered which otherwise would not appear.

Topic 5. ASSOCIATION OF IDEAS.

Section 50.

The question of association is essentially significant for lawyers because, in many cases, it is only by use of it that we can discover the conditions of the existence of certain conceptions, by means of which witnesses may be brought to remember and tell the truth, etc., without hypnotizing them, or overtesting the correctness of their statements. We will cursorily make a few general observations only:

Concerning the law of association, very little has been learned since the time of Aristotle. It is determined by:

1. Similarity (the common quality of the symbol).

2. Contrast (because every image involves opposition between its extremes).

3. Co-existence, simultaneity (the being together of outer or inner objects in space).

4. Succession (images call each other out in the same order in which they occur).

Hume recognized only three grounds of association of objects— similarity, contact in time and space, and causality. Theo. Lipps recognizes as the really different grounds of association only similarity and simultaneity (the simultaneity of their presence in the mind, especially).

If, however, simultaneity is to be taken in this sense it may be considered the sole ground of association, for if the images are not simultaneous there can be no question of association. Simultaneity in the mind is only the second process, for images are simultaneous in the mind only because they have occurred simultaneously, existed in the same space, were similar, etc. Münsterberg,[1] who dealt with the matter and got important results, points out that all so-called inner associations, like similarity, contrast, etc., may be reduced to external association, and all the external associations, even that of

temporal sequence, may be reduced to co-existence, and all co-existence-associations are psychophysically intelligible. Further: "The fundamental error of all association processes leading to incorrect connection of ideas, must be contained in their incompleteness. One idea was associated with another, the latter with a third, and then we connect the first with the third . . . a thing we should not have done, since the first, while it co-existed with the second, was also connected with many others."

But even this account does not account for certain difficulties, because some associations are simply set aside, although they should have occurred. Man is inclined, according to Stricker, to inhibit associations which are not implied in his "funded" complexes.

If we find direct contradiction with regard to associations, the way out is not easy. We have then, first, to consider how, by comparatively remote indirection, to introduce those conditions into the "funded" complex, which will give rise to the association. But such a consideration is often a big problem in pedagogy, and we are rarely in the position of teaching the witness.

There is still the additional difficulty that we frequently do not know the circumstance with the help of which the witness has made his association. Thomas Hobbes tells the story of an association which involved a leap from the British Civil War to the value of a denarius under the Emperor Tiberius. The process was as follows: King Charles I was given up by the Scotch for $200,000, Christ was sold for 80 denarii, what then was a denarius worth? In order to pursue the thread of such an association, one needs, anyway, only a definite quantity of historical knowledge, but this quantity must be possessed. But such knowledge is a knowledge of universal things that anybody may have, while the personal relations and purely subjective experiences which are at the command of an individual are quite unknown to any other person, and it is often exceedingly difficult to discover them.[2] The case is simplest when one tries to aid the memory of a witness in order to make him place single dates, e. g., when the attempt is made to determine some time and the witness is reminded of certain events that occurred during the time in question in order to assist him in fixing the calendar time. Or again, when the witness is brought to the place of the crime and the individual conditions are associated with the local situation. But when not merely single dates are to

be associated, when complete events are to be associated, a profound knowledge of the situation must precede, otherwise no association is successful, or merely topsy-turvy results are attained. The difficulties which here ensue depend actually upon the really enormous quantity of knowledge every human being must possess in making use of his senses. Anything that a man has learned at school, in the newspapers, etc., we know approximately, but we have no knowledge of what a man has thought out for himself and what he has felt in his localized conditions, e. g., his home, his town, his travels, his relations and their experiences, etc.—However important this may be, we have no means of getting hold of it.

Those associations which have physical expression are of importance only in particular cases. For example, the feeling of ants all over the body when you think that you have been near an ant-hill, or the feeling of physical pain on hearing the description of wounds. It is exceedingly funny to see how, during the lectures of dermatologists, the whole audience scratches that part of the body which is troubling the patient who is being described.

Such associations may be legally valuable in so far as the accused who plead innocence make unconscious movements which imply the denied wounds. In any event, it is necessary to be cautious because frequently the merely accurate description of a wound may bring about the same effect in nervous persons as the sight of that wound. If, however, the wound is not described and even its place not mentioned, and only the general harm is spoken of, then if the accused reaches for that part of his body in which the wound of his victim is located, you have a clew, and your attention should be directed upon it. Such an index is worth no more, but even as a clew it has some value.

All in all, we may say that the legally significant direction of association falls in the same class with "getting an idea." We need association for the purpose of constructing an image and an explanation of the event in question; something must "occur to us." We must "get an idea," if we are to know how something happened. We need association, moreover, in order to discover that something has occurred to the witness.

"Getting an idea" or "occurrence" is essentially one and the same in all its forms. We have only to study its several manifestations:

1. "Constructive occurrence," by means of which the correct thing may possibly be discovered in the way of combining, inferring,

comparing and testing. Here the association must be intentional and such ideas must be brought to a fixed image, which may be in such wise associated with them as to make a result possible. Suppose, e. g., that the case is one of arson, and the criminal is unknown. Then we will require the plaintiff to make local, temporal, identifying, and contrasting associations with the idea of all and each of his enemies, or of discharged servants, beggars, etc. In this wise we can attain to other ideas, which may help us to approach some definite theory.

2. "Spontaneous occurrence" in which a thought appears with apparent suddenness for no particular reason. As a matter of fact, such suddenness is always caused by some conscious, and in most cases, some unconscious association, the thread of which can not be later sought out and exhibited because of its being subconscious, or of its being overleaped so quickly and readily that it can not be traced. Very often some particular sense-perception exercises an influence which unites simultaneous ideas, now here again united. Suppose once during some extraordinary sound, e. g., the ringing of a bell, which I do not often hear, I had seen somebody. Now when I hear that bell ringing I will think of the person without perhaps knowing the definite association—i. e., the connection of the man with the tone of the bell occurs unconsciously. This may go still further. That man, when I first saw him, might have worn, perhaps, a red necktie, let us say poppy-red—it may now happen that every time I hear that bell-note I think of a field of poppy-flowers. Now who can pursue this road of association?

3. "Accluding occurrence," in which, in the process of the longest possible calm retention of an idea, another appears of itself and associates with the first. E. g., I meet a man who greets me although I do not recognize him. I may perhaps know who he is, but I do not spontaneously think of it and can not get at his identity constructively, because of lack of material. I therefore expect something from this "accluding occurrence" and with my eyes shut I try as long as possible to keep in mind the idea of this man. Suddenly, I see him before me with serious face and folded hands, on his right a similar individual and a similar one on his left, above them a high window with a curtain—the man was a juryman who sat opposite me. But the memory is not exhausted with this. I aim to banish his image as seated and keep him again before my eyes. I see an apparent gate beyond him with shelves behind; it is the image of a shop-keeper in a small town who is standing before

the door of his shop. I hold this image straining before my eyes— suddenly a wagon appears with just that kind of trapping which I have only once seen to deck the equipage of a land-owner. I know well who this is, what the little town near his estate is called, and now I suddenly know that the man whose name I want to remember is the merchant X of Y who once was a juryman in my court. This means of the longest possible retention of an idea, I have made frequent use of with the more intelligent witnesses (it rarely succeeds with women because they are restless), and all in all, with surprising effects.

4. "Retrospective occurrence," which consists of the development of associations backward. E. g.—do what I will, I can not remember the name of a certain man, but I know that he has a title to nobility, which is identical with the name of a small town in Obertfalz. Finally, the name of the town Hirschau occurs to me, and now I easily associate backwards, "Schaller von Hirschau." It is, of course, natural that words should unroll themselves forwards with habitual ease, but backwards only when we think of the word we are trying to remember, as written, and then associate the whole as a MS. image. This is unhappily difficult to use in helping another.

Topic 6. RECOLLECTION AND MEMORY.

Section 51.

In direct connection with the association of ideas is our recollection and memory, which are only next to perception in legal importance in the knowledge of the witness. Whether the witness wants to tell the truth is, of course, a question which depends upon other matters; but whether he can tell the truth depends upon perception and memory. Now the latter is a highly complicated and variously organized function which is difficult to understand, even in the daily life, and much more so when everything depends upon whether the witness has noticed anything, how, how long, what part of the impression has sunk more deeply into his mind, and in what direction his defects of memory are to be sought. It would be inexcusable in the lawyer not to think about this and to make equivalent use of all the phenomena that are presented to him. To overlook the rich literature and enormous work that has been devoted to this subject is to raise involuntarily the question, for whom was it all done? Nobody needs a thorough-going knowledge of the essence of memory more than the lawyer.

I advise every criminalist to study the literature of memory and recommend the works of Münsterberg, Ribot, Ebbinghaus, Cattell, Kräpelin, Lasson, Nicolai Lange, Arreat, Richet, Forel, Galton, Biervliet, Paneth, Fauth, Sander, Koch, Lehmann, Féré, Jodl,[1] etc.

Section 52. (a) The Essence of Memory.

Our ignorance concerning memory is as great as its universal importance, and as our indebtedness to it for what we are and possess. At best we have, when explaining it, to make use of images.

Plato accounts for memory in the "Theaetetus" by the image of the seal ring which impresses wax; the character and duration of the impression depends upon the size, purity, and hardness of the wax. Fichte says, "The spirit does not conserve its products,— the single ideas, volitions, and feelings are conserved by the mind and constitute the ground of its inexhaustibly retentive memory. . . . The possibility of recalling what has once been independently done, this remains in the spirit." James Sully compares the receptivity of memory with the infusion of dampness into an old MS. Draper also brings a physical example: If you put a flat object upon the surface of a cold, smooth metal and then breathe on the metal and, after the moisture has disappeared, remove the object, you may recall its image months after, whenever you breathe on the place in question. Another has called memory the safe of the mind. It is the opinion of E. Hering[1] that what we once were conscious of and are conscious of again, does not endure as image but as echo such as may be heard in a tuning fork when it is properly struck. Reid asserts that memory does not have present ideas, but past things for its object, Natorp explains recollection as an identification of the unidentical, of not-now with now. According to Herbart and his school,[2] memory consists in the possibility of recognizing the molecular arrangements which had been left by past impressions in the ganglion

cells, and in reading them in identical fashion. According to Wundt and his pupils, the problem is one of the disposition of the central organs. And it is the opinion of James Mill that the content of recollection is not only the idea of the remembered object, but also the idea that the object had been experienced before. Both ideas together constitute the whole of that state of mind which we denote as memory. Spinoza[3] deals freely with memory, and asserts that mankind does not control it inasmuch as all thoughts, ideas, resolutions of spirits, are bare results of memories, so that human freedom is excluded. Uphues[4] distinguishes between memory and the conception which is presupposed in the recognition of an object different from that conception. This is the theory developed by Aristotle.

According to Berkeley and Hume recognition is not directed upon a different object, nor does it presuppose one; the activity of recognition consists either in the exhibition or the creation of the object. Recognition lends the idea an independence which does not belong to it and in that way turns it into a thing, objectifies it, and posits it as substantial. Maudsley makes use of the notion that it is possible to represent any former content of consciousness as attended to so that it may again come into the center of the field of consciousness. Dorner[5] explains recognition as follows: "The possible is not only the merely possible in opposition to the actual; it is much more proper to conceive being as possible, i. e., as amenable to logical thinking; without this there could be no recognition." Külpe[6] concerns himself with the problem of the difference between perceptive images and memory images and whether the latter are only weaker than the former as English philosophers and psychologists assert. He concludes that they are not so.

When we take all these opinions concerning memory together we conclude that neither any unity nor any clear description of the matter has been attained. Ebbinghaus's sober statement may certainly be correct: "Our knowledge of memory rises almost exclusively from the observation of extreme, especially striking cases. Whenever we ask about more special solutions concerning the detail of what has been counted up, and their other relations of dependence, their structure, etc., there are no answers."

Nobody has as yet paid attention to the simple daily events which constitute the routine of the criminalists. We find little instruction concerning them, and our difficulties as well as our mistakes are thereby increased. Even the modern repeatedly cited experimental investigations have no direct bearing upon our work.

We will content ourselves with viewing the individual conceptions of memory and recollection as occurring in particular cases and with considering them, now one, now the other, according to the requirements of the case. We shall consider the general relation of "reproduction" to memory. "Reproduction" we shall consider in a general sense and shall subsume under it also the so-called involuntary reproductions which rise in the forms and qualities of past events without being evoked, i. e., which rise with the help of unconscious activity through the more or less independent association of ideas. Exactly this unconscious reproduction, this apparently involuntary activity, is perhaps the most fruitful, and we therefore unjustly meet with unexceptionable distrust the later sudden "occurrence," especially when these occurrences happen to defendant and his witnesses. It is true that they frequently deceive us because behind the sudden occurrence there often may be nothing more than a better training and instruction from experienced cell-mates; though very often the circumstances are such that the suspect has succeeded through some released prisoner, or by a blackened letter, in sending a message from his prison, by means of which false witnesses of alibi, etc., are provided. Distrust is in any event justified, when his most important witnesses suddenly "occur" to the accused. But this does not always happen, and we find in our own experience evidence of the fact that memory and the capacity to recall something often depend upon health, feeling, location, and chance associations which can not be commanded, and happen as accidentally as anything in life can. That we should remember anything at all depends upon the point of time. Everybody knows how important twilight may be for memory. Indeed, twilight has been called the visiting-hour of recollection, and it is always worth while to observe the situation when anybody asserts that some matter of importance occurred to him in the twilight. Such an assertion merits, at least, further examination. Now, if we only know how these occurrences constitute themselves, it would not be difficult to study them out and to estimate their probability. But we do not know, and we have to depend, primarily, on observation

and test. Not one of the theories applied is supported by experience altogether.

They may be divided into three essential groups.

1. What is received, fades away, becomes a "trace," and is more or less overlaid by new perceptions. When these latter are ever set aside, the old trace comes into the foreground.

2. The ideas sink, darken, and disintegrate. If they receive support and intensification they regain complete clearness.

3. The ideas crumble up, lose their parts. When anything occurs that reunites them and restores what is lost, they become whole again.

Ebbinghaus maintains, correctly enough, that not one of these explanations is universally satisfactory, but it must be granted that now one, now another is useful in controlling this or that particular case. The processes of the destruction of an idea, may be as various as those of the destruction and restoration of a building. If a building is destroyed by fire, I certainly can not explain the image given by merely assuming that it was the victim of the hunger of time. A building which has suffered because of the sinking of the earth I shall have to image by quite other means than those I would use if it had been destroyed by water.

For the same reason when, in court, somebody asserts a sudden "occurrence," or when we want to help him and something occurs to him, we shall have to proceed in different fashion and determine our action empirically by the conditions of the moment. We shall have to go back, with the help of the witness, to the beginning of the appearance of the idea in question and study its development as far as the material permits us. In a similar manner we must make use of every possibility of explanation when we are studying the disappearance of ideas. At one point or another we shall find certain connections. One chief mistake in such reconstructive work lies in overlooking the fact that no individual is merely passive when he receives sensations; he is bound to make use of a certain degree of activity. Locke and Bonnet have already mentioned this fact, and anybody may verify it by comparing his experiments of trying to avoid seeing or hearing, and trying actively to see or to hear. For this reason it is foolish to ask anybody how it happened that he perceived less than another, because both have equally good senses and were able to perceive as much. On the other hand, the grade of activity each has made use of in perception is rarely inquired into, and this is the more unfortunate because memory is often proportionate

to activity. If, then, we are to explain how various statements concerning contemporaneous matters, observed a long time ago, are to be combined, it will not be enough to compare the memory, sensory acuteness, and intelligence of the witnesses. The chief point of attention should be the activity which has been put in motion during the sense-perception in question.

Section 53. (b) The Forms of Reproduction.

Kant analyzes memory:

1. As apprehending something in memory.

2. As retaining it for a long time.

3. As immediately recalling it.

One might, perhaps add, as 4: that the memory-image is most conformable to the actual one. This is not identical with the fact that we recollect at all. It is to be assumed that the forms of memory-images vary very much with different persons, because each individual verifies his images of various objects variously. I know two men equally well for an equal time, and yet have two memory-images of them. When I recall one, a life-sized, moving, and moved figure appears before me, even the very man himself; when I think of the other, I see only a small, bare silhouette, foggy and colorless, and the difference does not require that the first shall be an interesting and the second a boresome individual. This is still clearer in memory of travels. One city appears in recollection with size, color and movement, real; the other, in which I sojourned for the same length of time and only a few days later, under similar conditions of weather, etc., appears like a small, flat photograph. Inquiry reveals that this is as true of other people as of me, and that the problem of memory is much differentiated by the method of recollection. In fact, this is so little in doubt that at some periods of time there are more images of one sort than of another and what is a rule for one kind of individual is an exception for another.

Now there is a series of phenomena for which we possess particular types of images which often have little to do with the things themselves. So Exner says: "We might know the physiognomy of an individual very accurately, be able to pick him out among a thousand, without being clear about the differences between him and another; indeed, we often do not know the color of his eyes and hair, yet marvel when it suddenly becomes different."

Kries[1] calls attention to another fact: "When we try to mark in

memory the contour of a very well-known coin, we deceive ourselves, unbelievably—when we see the coin the size we imagine it to be, we wonder still more."

Lotze shows correctly that memory never brings back a blinding flash of light, or the over-powering blow of an explosion with the intensity of the image in proper relation to the impression. I believe that it is not necessary to go so far, for example, and hold that not even the sparkling of a star, the crack of a pistol, etc., are kept in memory with more than partial implication of the event. Maudsley points out correctly that we can have no memory of pain—"because the disturbance of nervous elements disappears just as soon as their integrity is again established." Perhaps, also, because when the pain has disappeared, the tertium comparationis is lacking. But one need not limit oneself to pain, but may assert that we lack memory of all unpleasant sensations. The first time one jumps into the water from a very high spring-board, the first time one's horse rises over a hurdle, or the first time the bullets whistle past one's ear in battle, are all most unpleasant experiences, and whoever denies it is deceiving himself or his friends. But when we think of them we feel that they were not so bad, that one merely was very much afraid, etc. But this is not the case; there is simply no memory for these sensations.

This fact is of immense importance in examination and I believe that no witness has been able effectively to describe the pain caused by a body wound, the fear roused by arson, the fright at a threat, not, indeed, because he lacked the words to do so, but because he had not sufficient memory for these impressions, and because he has nothing to-day with which to compare them. Time, naturally, in such cases makes a great difference, and if a man were to describe his experiences shortly after their uncomfortable occurrence he would possibly remember them better than he would later on. Here, if the examiner has experienced something similar, years ago, he is likely to accuse the witness of exaggeration under the belief that his own experience has shown the thing to be not so bad. Such an accusation will be unjust in most instances. The differences in conception depend to a large degree on differences in time, and consequent fading in memory. Several other particular conditions may be added.

Kant, e. g., calls attention to the power we have over our fancy: "In memory, our will must control our imagination and our imagination

must be able to determine voluntarily the reproduction of ideas of past time."

But these ideas may be brought up not only voluntarily; we have also a certain degree of power in making these images clearer and more accurate. It is rather foolish to have the examiner invite the witness to "exert his memory, to give himself the trouble, etc." This effects nothing, or something wrong. But if the examiner is willing to take the trouble, he may excite the imagination of the witness and give him the opportunity to exercise his power over the imagination. How this is done depends naturally upon the nature and education of the witness, but the judge may aid him just as the skilful teacher may aid the puzzled pupil to remember. When the pianist has completely forgotten a piece of music that he knew very well, two or three chords may lead him to explicate these chords forward or backward, and then—one step after another—he reproduces the whole piece. Of course the chords which are brought to the mind of the player must be properly chosen or the procedure is useless.

There are rules for the selection of these clews. According to Ebbinghaus: "The difference in the content of the recollected is due to discoverable causes. Melodies may become painful because of their undesirable obstinacy in return. Forms and colors do not usually recur, and if they do, they do so with noticeable claims on distinctness and certainty. Past emotional conditions are reproduced only with effort, in comparatively pallid schemes, and often only by means of the accompanying movements." We may follow these clews, in some directions at least, to our advantage. Of course, nobody will say that one should play tunes to witnesses in order to make them remember, because the tunes have sunk into the memory with such undesirable obstinacy as to be spurs to recollection. It is just as futile to operate with forms and colors, or to excite emotional conditions. But what has been said leads us back to the ancient rule of working so far as is possible with the constantly well-developed sense of location. Cicero already was aware of this

"Tanta vis admonitionis inest in locis, id quidem infinitum in hac urbe, quocumque enim ingredimur, in aliquam historiam vestigium possumus." Indeed he deduces his whole doctrine of memory from the sense of location, or he at least justifies those who do so.

If, then, we bring a witness, who in our court house recollects nothing, in locum rei sitae, all the mentioned conditions act favorably.[2]

The most influential is the sense of location itself, inasmuch as every point at which something significant occurred not only is the content of an association, but is also the occasion of one. It is, moreover, to be remembered that reproduction is a difficult task, and that all unnecessary additional difficulties which are permitted to accrue, definitely hinder it. Here, too, there is only a definite number of units of psychical energy for use, and the number which must be used for other matters is lost to the principal task. If, e. g., I recall an event which had occurred near the window of a definite house, I should have considerable difficulty to recall the form of the house, the location of the window, its appearance, etc., and by the time this attempt has barely begun to succeed, I have made so much effort that there is not sufficient power left for the recollection of the event we are really concerned with. Moreover, a mistake in the recollection of extraneous objects and the false associations thereby caused, may be very disturbing to the correctness of the memory of the chief thing. If, however, I am on the spot, if I can see everything that I had seen at the time in question, all these difficulties are disposed of.

We have still to count in the other conditions mentioned above. If acoustic effects can appear anywhere, they can appear in the locality where they first occurred. The same bell ringing, or a similar noise, may occur accidentally, the murmur of the brook is the same, the rustle of the wind, determined by local topography, vegetation, especially by trees, again by buildings, varies with the place. And even if only a fine ear can indicate what the difference consists of, every normal individual senses that difference unconsciously. Even the "universal noise," which is to be found everywhere, will be differentiated and characteristic according to locality, and that, together with all these other things, is extraordinarily favorable to the association of ideas and the reproduction of the past. Colors and forms are the same, similar orders may occur, and possibly the same attitudes are awakened, since these depend in so great degree upon external conditions. Now, once these with their retrospective tendencies are given, the recollection of any contemporary event increases, as one might say, spontaneously. Whatever may especially occur to aid the memory of an event, occurs best at the place where the event itself happened, and hence, one can not too insistently advise the examination of witnesses, in important cases, only in loco rei sitae. Incidentally, the judge himself learns the real

situation and saves himself, thereby, much time and effort, for he is enabled in a few words to render the circumstantial descriptions which have to be composed with so much difficulty when the things are not seen and must be derived from the testimonies of the witnesses themselves.

Whoever does not believe in the importance of conducting the examination at the place of an event, needs only to repeat his examination twice, once at the court, and again at the place—then he certainly will doubt no more. Of course the thing should not be so done that the event should be discussed with the witness at the place of its occurrence and then the protocol written in the house of the mayor, or in an inn half an hour away—the protocol must to the very last stroke of the pen be written then and there, in order that every impression may be renewed and every smallest doubt studied and corrected. Then the differences between what has passed, what has been later added, and what is found to-day can be easily determined by sticking to the rule of Uphues, that the recognition of the present as present is always necessary for the eventual recognition of the past. Kant has already suggested what surprising results such an examination will give: "There are many ideas which we shall never again in our lives be conscious of, unless some occasion cause them to spring up in the memory." But such a particularly powerful occasion is locality, inasmuch as it brings into play all the influences which our senses are capable of responding to.[3]

Of course the possibility of artificially-stimulated memory disappears like all memory, with the lapse of time. As a matter of fact, we know that those of our experiences which concern particular persons and things, and which are recalled at the sight of those persons and things, become, later on, when the connections of images have been broken, capable only of awakening general notions, even though the persons or things are as absolutely present as before. But very unfavorable circumstances must have been at work before such a situation can develop.

It is characteristic, as is popularly known, that memory can be intensified by means of special occasions. It is Höfler's opinion that the Spartan boys were whipped at the boundary stones of their country in order that they might recall their position, and even now-a-days our peasants have the custom, when setting up new boundary stones, of grasping small boys by the ears and hair in

order that they shall the better remember the position of the new boundary mark when, as grown men, they will be questioned about it. This being the case, it is safer to believe a witness when he can demonstrate some intensely influential event which was contemporaneous with the situation under discussion, and which reminds him of that situation.

Section 54. (c) The Peculiarities of Reproduction.

The differences in memory which men exhibit are not, among their other human qualities, the least. As is well known, this difference is expressed not only in the vigor, reliability, and promptness of their memory, but also in the field of memory, in the accompaniment of rapid prehensivity by rapid forgetfulness, or slow prehensivity and slow forgetfulness, or in the contrast between narrow, but intense memory, and broad but approximate memory.

Certain special considerations arise with regard to the field of greatest memory. As a rule, it may be presupposed that a memory which has developed with especial vigor in one direction has generally done this at the cost of memory in another direction. Thus, as a rule, memory for numbers and memory for names exclude each other. My father had so bad a memory for names that very frequently he could not quickly recall my Christian name, and I was his own son. Frequently he had to repeat the names of his four brothers until he hit upon mine, and that was not always a successful way.[1] When he undertook an introduction it was always: "My honored m—m—m,"—"The dear friend of my youth m—m—m." On the other hand, his memory for figures was astounding. He noted and remembered not only figures that interested him for one reason or another, but also those that had not the slightest connection with him, and that he had read merely by accident. He could recall instantaneously the population of countries and cities, and I remember that once, in the course of an accidental conversation, he mentioned the production of beetroot in a certain country for the last ten years, or the factory number of my watch that he had given me fifteen years before and had never since held in his hand. He often said that the figures he carried in his head troubled him. In this regard the symptom may be mentioned that he was not a good mathematician, but so exceptional a card player that nobody wanted to play with him. He noticed

every single card dealt and could immediately calculate what cards each player had, and was able to say at the beginning of the game how many points each must have.

Such various developments are numerous and of importance for us because we frequently are unwilling to believe the witness testifying in a certain field for the reason that his memory in another field had shown itself to be unreliable. Schubert and Drobisch cite examples of this sort of thing, but the observations of moderns, like Charcot and Binet, concerning certain lightning calculators (Inaudi, Diamandi, etc.), confirm the fact that the memory for figures is developed at the expense of other matters. Linné tells that Lapps, who otherwise note nothing whatever, are able to recognize individually each one of their numberless reindeer. Again, the Dutch friend of flowers, Voorhelm, had a memory only for tulips, but this was so great that he could recognize twelve hundred species of tulips merely from the dry bulbs.

These fields seem to be of a remarkably narrow extent. Besides specialists (numismatists, zoologists, botanists, heralds, etc.) who, apart from their stupendous memory for their particular matters, appear to have no memory for other things, there are people who can remember only rhymes, melodies, shapes, forms, titles, modes, service, relationships, etc. V. Volkmar has devoted some space to showing this. He has also called attention to the fact that the semi-idiotic have an astounding memory for certain things. This has been confirmed by other students. One of them, Du Potet,[2] who is perhaps the expert in the popular mind of the Austrian Alps, has made it especially clear. As in all mountainous regions there are a great number of those unfortunate idiots who, when fully developed, are called cretins, and in their milder form are semi-human, but do not possess intelligence enough to earn their own living. Nevertheless, many of them possess astounding memories for certain things. One of them is thoroughly conversant with the weather prophecy in the calendar for the past and the present year, and can cite it for each day. Another knows the day and the history of every saint of the Catholic church. Another knows the boundaries of every estate, and the name, etc., of its owner. Another knows each particular animal in a collective herd of cattle, knows to whom it belongs, etc. Of course not one of these unfortunates can read. Drobisch mentions an idiotic boy, not altogether able to speak, who, through the untiring efforts of a lady, succeeded finally in

learning to read. Then after hasty reading of any piece of printed matter, he could reproduce what he had read word for word, even when the book had been one in a foreign and unknown tongue. Another author mentions a cretin who could tell exactly the birthdays and death-days of the inhabitants of his town for a decade.

It is a matter of experience that the semi-idiotic have an excellent memory and can accurately reproduce events which are really impressive or alarming, and which have left effects upon them. Many a thing which normal people have barely noticed, or which they have set aside in their memory and have forgotten, is remembered by the semi-idiotic and reproduced. On the contrary, the latter do not remember things which normal people do, and which in the latter frequently have a disturbing influence on the important point they may be considering. Thus the semi-idiotic may be able to describe important things better than normal people. As a rule, however, they disintegrate what is to be remembered too much, and offer too little to make any effective interpretation possible. If such a person, e. g., is witness of a shooting, he notices the shot only, and gives very brief attention to what precedes, what follows, or what is otherwise contemporary. Until his examination he not only knows nothing about it, but even doubts its occurrence. This is the dangerous element in his testimony. Generally it is right to believe his kind willingly. "Children and fools tell the truth," what they say bears the test, and so when they deny an event there is a tendency to overlook the fact that they have forgotten a great deal and hence to believe that the event had really not occurred.

Similar experiences are yielded in the case of the memory of children. Children and animals live only in the present, because they have no historically organic ideas in mind. They react directly upon stimuli, without any disturbance of their idea of the past. This is valid, however, only for very small children. At a later age children make good witnesses, and a well-brought-up boy is the best witness in the world. We have only to keep in mind that later events tend in the child's mind to wipe out earlier ones of the same kind.[3] It used to be said that children and nations think only of the latest events. And that is universally true. Just as children abandon even their most precious toys for the sake of a new one, so they tell only the latest events in their experience. And this is especially the case when there are a great many facts—

e. g., repeated mal-treatment or thefts, etc. Children will tell only of the very last, the earlier one may absolutely have disappeared from the memory.

Bolton,[4] who has made a systematic study of the memory of children, comes to the familiar conclusion that the scope of memory is measured by the child's capacity of concentrating its attention. Memory and acute intelligence are not always cognate (the latter proposition, true not for children alone, was known to Aristotle). As a rule girls have better memory than boys (it might also be said that their intelligence is generally greater, so long as no continuous intellectual work, and especially the creation of one's own ideas, is required). Of figures read only once, children will retain a maximum of six. (Adults, as a rule, also retain no more.) The time of forgetting in general has been excellently schematized by Ebbinghaus. He studied the forgetting of a series of thirteen nonsense syllables, previously learned, in such a way as to be able to measure the time necessary to re-learn what was forgotten. At the end of an hour he needed half the original time, at the end of eight hours two-thirds of that time. Then the process of loss became slower. At the end of twenty-four hours he required a third, at the end of six days a fourth, at the end of a month a clear fifth, of the time required at first.

I have tested this in a rough way on various and numerous persons, and invariably found the results to tally. Of course, the measure of time alters with the memory in question, but the relations remain identical, so that one may say approximately how much may be known of any subject at the end of a fixed time, if only one ratio is tested. To criminalists this investigation of Ebbinghaus' is especially recommended.

The conditions of prehensivity of particular instances are too uncertain and individual to permit any general identifications or differentiations. There are certain approximating propositions— e. g., that it is easier to keep in mind rhymed verse than prose, and definite rows and forms than block masses. But, on the one hand, what is here involved is only the ease of memory, not the content of memory, and on the other hand there are too many exceptions —e. g., there are many people who retain prose better than verse. Hence, it is not worth while to go further in the creation of such rules. Forty or fifty years ago, investigations looking toward them

had been pursued with pleasure, and they are recorded in the journals of the time.

That aged persons have, as is well known, a good memory for what is long past, and a poor one for recent occurrences is not remarkable. It is to be explained by the fact that age seems to be accompanied with a decrease of energy in the brain, so that it no longer assimilates influences, and the imagination becomes dark and the judgment of facts incorrect. Hence, the mistakes are those of apperception of new things,—what has already been perceived is not influenced by this loss of energy.

Again, it should not rouse astonishment that so remarkable and delicately organized a function as memory should be subject to anomalies and abnormalities of all kinds. We must take it as a rule not to assume the impossibility of the extraordinary phenomena that appear and to consult the expert about them.[5] The physician will explain the pathological and pathoformic, but there is a series of memory-forms which do not appear to be diseased, yet which are significantly rare and hence appear improbable. Such forms will require the examination of an experienced expert psychologist who, even when unable to explain the particular case, will still be able to throw some light on it from the literature of the subject. This literature is rich in examples of the same thing; they have been eagerly collected and scientifically studied in the earlier psychological investigations. Modern psychology, unfortunately, does not study these problems, and in any event, its task is so enormous that the practical problems of memory in the daily life must be set aside for a later time. We have to cite only a few cases handled in literature.

The best known is the story of an Irish servant girl, who, during fever, recited Hebrew sentences which she had heard from a preacher when a child. Another case tells of a very great fool who, during fever, repeated prolonged conversations with his master, so that the latter decided to make him his secretary. But when the servant got well he became as foolish as ever. The criminalist who has the opportunity of examining deeply wounded, feverish persons, makes similar, though not such remarkable observations. These people give him the impression of being quite intelligent persons who tell their stories accurately and correctly. Later on, after they are cured, one gets a different opinion of their intelligence. Still more frequently one observes that these feverish, wounded victims know

more, and know more correctly about the crime than they are able to tell after they have recovered. What they tell, moreover, is quite reliable, provided, of course, they are not delirious or crazy.

The cases are innumerable in which people have lost their memory for a short time, or for ever. I have already elsewhere mentioned an event which happened to a friend of mine who received a sudden blow on the head while in the mountains and completely lost all memory of what had occurred a few minutes before the blow. After this citation I got a number of letters from my colleagues who had dealt with similar cases. I infer, therefore, that the instances in which people lose their memory of what has occurred before the event by way of a blow on the head, are numerous.[6]

Legally such cases are important because we would not believe statements in that regard made by accused, inasmuch as there seems to be no reason why the events before the wound should disappear, just as if each impression needed a fixative, like a charcoal drawing. But as this phenomenon is described by the most reliable persons, who have no axe to grind in the matter, we must believe it, other things being equal, even when the defendant asserts it. That such cases are not isolated is shown in the fact that people who have been stunned by lightning have later forgotten everything that occurred shortly before the flash. The case is similar in poisoning with carbonic-acid gas, with mushrooms, and in strangulation. The latter cases are especially important, inasmuch as the wounded person, frequently the only witness, has nothing to say about the event.

I cannot omit recalling in this place a case I have already mentioned elsewhere, that of Brunner. In 1893 in the town of Dietkirchen, in Bavaria, the teacher Brunner's two children were murdered, and his wife and servant girl badly wounded. After some time the woman regained consciousness, seemed to know what she was about, but could not tell the investigating justice who had been sent on to take charge of the case, anything whatever concerning the event, the criminal, etc. When he had concluded his negative protocol she signed it, Martha Guttenberger, instead of Martha Brunner. Fortunately the official noted this and wanted to know what relation she had to the name Guttenberger. He was told that a former lover of the servant girl an evil-mouthed fellow, was called by that name. He was traced to Munich and there arrested. He immediately confessed to the crime. And when Mrs. Brunner

became quite well she recalled accurately that she had definitely recognized Guttenberger as the murderer.[7]

The psychological process was clearly one in which the idea, "Guttenberger is the criminal," had sunk into the secondary sphere of consciousness, the subconsciousness,—so that it was only clear to the real consciousness that the name Guttenberger had something to do with the crime. The woman in her weakened mental condition thought she had already sufficiently indicated this fact, so that she overlooked the name, and hence wrote it unconsciously. Only when the pressure on her brain was reduced did the idea that Guttenberger was the murderer pass from the subconscious to the conscious. Psychiatrists explain the case as follows:

The thing here involved is retrograde amnesia. It is nowadays believed that this phenomenon in the great majority of cases occurs according to the rule which defines traumatic hysteria, i. e., as ideogen. The ideational complexes in question are forced into the subconsciousness, whence, on occasion, by aid of associative processes, hypnotic concentration, and such other similar elements, they can be raised into consciousness. In this case, the suppressed ideational complex manifested itself in signing the name.

All legal medicine discusses the fact that wounds in the head make people forget single words. Taine, Guerin, Abercrombie, etc., cite many examples, and Winslow tells of a woman who, after considerable bleeding, forgot all her French. The story is also told that Henry Holland had so tired himself that he forgot German. When he grew stronger and recovered he regained all he had forgotten.

Now would we believe a prisoner who told us any one of these things?

The phenomena of memories which occur in dying persons who have long forgotten and never even thought of these memories, are very significant. English psychologists cite the case of Dr. Rush, who had in his Lutheran congregation Germans and Swedes, who prayed in their own language shortly before death, although they had not used it for fifty or sixty years. I can not prevent myself from thinking that many a death-bed confession has something to do with this phenomenon.[8]

At the boundary between incorrect perception and forgetting are those cases in which, under great excitement, important events

do not reach consciousness. I believe that the responsibility is here to be borne by the memory rather than by sense-perception. There seems to be no reason for failing to perceive with the senses under the greatest excitement, but there is some clearness in the notion that great excitement causes what has just been perceived to be almost immediately forgotten. In my "Manual" I have discussed a series of cases of this sort, and show how the memory might come into play. None of the witnesses, e. g., had seen that Mary Stuart received, when being executed, two blows. In the case of an execution of many years ago, not one of those present could tell me the color of the gloves of the executioner, although everyone had noticed the gloves. In a train wreck, a soldier asserted that he had seen dozens of smashed corpses, although only one person was harmed. A prison warden who was attacked by an escaping murderer, saw in the latter's hand a long knife, which turned out to be a herring. When Carnot was murdered, neither one of the three who were in the carriage with him, nor the two footmen, saw the murderer's knife or the delivery of the blow, etc.

How often may we make mistakes because the witnesses—in their excitement—have forgotten the most important things!

Section 55. (d) Illusions of Memory.

Memory illusion, or paramnesia, consists in the illusory opinion of having experienced, seen, or heard something, although there has been no such experience, vision, or sound. It is the more important in criminal law because it enters unobtrusively and unnoticed into the circle of observation, and not directly by means of a demonstrated mistake. Hence, it is the more difficult to discover and has a disturbing influence which makes it very hard to perceive the mistakes that have occurred in consequence of it.

It may be that Leibnitz meant paramnesia with his "perceptiones insensibiles." Later, Lichtenberg must have had it in mind when he repeatedly asserted that he must have been in the world once before, inasmuch as many things seemed to him so familiar, although, at the time, he had not yet experienced them. Later on, Jessen concerned himself with the question, and Sander[1] asserts him to have been the first. According to Jessen, everybody is familiar with the phenomenon in which the sudden impression occurs, that

what is experienced has already been met with before so that the future might be predicted. Langwieser asserts that one always has the sensation that the event occurred a long time ago, and Dr. Karl Neuhoff finds that his sensation is accompanied with unrest and contraction. The same thing is discussed by many other authors.[2]

Various explanations have been offered. Wigand and Maudsley think they see in paramnesia a simultaneous functioning of both relations. Anje believes that illusory memory depends on the differentiation which sometimes occurs between perception and coming-into-consciousness. According to Külpe, these are the things that Plato interpreted in his doctrine of pre-existence.

Sully,[3] in his book on illusions, has examined the problem most thoroughly and he draws simple conclusions. He finds that vivacious children often think they have experienced what is told them. This, however, is retained in the memory of the adult, who continues to think that he has actually experienced it. The same thing is true when children have intensely desired anything. Thus the child-stories given us by Rousseau, Goethe, and De Quincey, must come from the airy regions of the dream life or from waking revery, and Dickens has dealt with this dream life in "David Copperfield." Sully adds, that we also generate illusions of memory when we assign to experiences false dates, and believe ourselves to have felt, as children, something we experienced later and merely set back into our childhood.

So again, he reduces much supposed to have been heard, to things that have been read. Novels may make such an impression that what has been read or described there appears to have been really experienced. A name or region then seems to be familiar because we have read of something similar.

It will perhaps be proper not to reduce all the phenomena of paramnesia to the same conditions. Only a limited number of them seem to be so reducible. Impressions often occur which one is inclined to attribute to illusory memory, merely to discover later that they were real but unconscious memory; the things had been actually experienced and the events had been forgotten. So, for example, I visit some region for the first time and get the impression that I have seen it before, and since this, as a matter of fact, is not the case, I believe myself to have suffered from an illusion of memory.

Later, I perceive that perhaps in early childhood I had really been in a country that resembled this one. Thus my memory was really correct; I had merely forgotten the experience to which it referred.

Aside from these unreal illusions of memory, many, if not all others, are explicable, as Sully indicates, by the fact that something similar to what has been experienced, has been read or heard, while the fact that it has been read or heard is half forgotten or has sunk into the subconsciousness. Only the sensation has remained, not the recollection that it was read, etc. Another part of this phenomenon may possibly be explained by vivid dreams, which also leave strong impressions without leaving the memory of their having been dreams. Whoever is in the habit of dreaming vividly will know how it is possible to have for days a clear or cloudy feeling of the discovery of something excellent or disturbing, only to find out later that there has been no real experience, only a dream. Such a feeling, especially the memory of things seen or heard in dreams, may remain in consciousness. If, later, some similar matter is really met with, the sensation may appear as a past event.[4] This is all the easier since dreams are never completely rigid, but easily modeled and adaptable, so that if there is the slightest approximation to similarity, memory of a dream lightly attaches itself to real experience.

All this may happen to anybody, well or ill, nervous or stolid. Indeed, Kräpelin asserts that paramnesia occurs only under normal circumstances. It may also be generally assumed that a certain fatigued condition of the mind or of the body renders this occurrence more likely, if it does not altogether determine it. So far as self-observation throws any light on the matter, this statement appears to be correct. I had such illusions of memory most numerously during the Bosnian war of occupation of 1878, when we made our terrible forced marches from Esseg to Sarajevo. The illusions appeared regularly after dinner, when we were quite tired. Then the region which all my preceding life I had not seen, appeared to be pleasantly familiar, and when once, at the very beginning, I received the order to storm a village occupied by Turks, I thought it would not be much trouble, I had done it so frequently and nothing had ever happened. At that time we were quite exhausted. Even when we had entered the otherwise empty village this extraordinary circumstance did not impress me, and I thought that the inside of

a village always looked like that—although I had never before seen such a Turkish street-hotel "in nature" or pictured.

Another mode of explanation may be mentioned, i. e., explanation by heredity. Hering[5] and Sully have dealt with it. According to the latter, especially, we may think that we have undergone some experience that really belongs to some ancestor. Sully believes that this contention can not be generically contradicted because a group of skilled activities (nest-building, food-seeking, hiding from the enemy, migration, etc.) have been indubitably inherited from the animals, but on the other hand, that paramnesia is inherited memory can be proved only with, e. g., a child which had been brought up far from the sea but whose parents and grandparents had been coast-dwellers. If that child should at first sight have the feeling that he is familiar with the sea, the inheritance of memory would be proved. So long as we have not a larger number of such instances the assumption of hereditary influence is very suggestive but only probable.

With regard to the bearing of memory-illusions on criminal cases I shall cite only one possible instance. Somebody just waking from sleep has perceived that his servant is handling his purse which is lying on the night-table, and in consequence of the memory-illusion he believes that he has already observed this many times before. The action of the servant was perhaps harmless and in no way directed toward theft. Now the evidence of the master is supposed to demonstrate that this has repeatedly occurred, then perhaps no doubt arises that the servant has committed theft frequently and has had the intention of doing so this time.

To generalize this situation would be to indicate that illusions of memory are always likely to have doubtful results when they have occurred only once and when the witness in consequence of paramnesia believes the event to have been repeatedly observed. It is not difficult to think of numbers of such cases but it will hardly be possible to say how the presence of illusions of memory is to be discovered without the knowledge that they exist.

When we consider all the qualities and idiosyncrasies of memory, this so varied function of the mind, we must wonder that its estimation in special cases is frequently different, although proceeding from a second person or from the very owner of the questionable memory. Sully finds rightly, that one of the keenest tricks in fighting deep-rooted

convictions is to attack the memory of another with regard to its reliability. Memory is the private domain of the individual. From the secret council-chamber of his own consciousness, into which no other may enter, it draws all its values.

The case is altered, however, when a man speaks of his personal memory. It must then assume all the deficiencies which belong to other mental powers. We lawyers, especially, hear frequently from witnesses: "My memory is too weak to answer this question," "Since receiving the wound in question my memory has failed," "I am already too old, my memory is leaving me," etc. In each of these cases, however, it is not the memory that is at fault. As a matter of fact the witness ought to have said "I am too stupid to answer this question," "Since the wound in question, my intellectual powers have failed," "I am already old, I am growing silly," etc. But of course no one will, save very rarely, underestimate his good sense, and it is more comfortable to assign its deficiencies to the memory. This occurs not only in words but also in construction. If a man has incorrectly reproduced any matter, whether a false observation, or a deficient combination, or an unskilled interpretation of facts, he will not blame these things but will assign the fault to memory. If he is believed, absolutely incorrect conclusions may result.

Section 56. (e) Mnemotechnique.

Just a few words concerning mnemotechnique, mnemonic, and anamnestic. The discovery of some means of helping the memory has long been a human purpose. From Simonides of Chios, to the Sophist Hippias of Elis, experiments have been made in artificial development of the memory, and some have been remarkably successful. Since the middle ages a large group of people have done this. We still have the figures of the valid syllogisms in logic, like Barbara, etc. The rules for remembering in the Latin grammar, etc., may still be learned with advantage. The books of Kothe and others, have, in their day, created not a little discussion.

As a rule, modern psychology pays a little attention to memory devices. In a certain sense, nobody can avoid mnemonic, for whenever you tie a knot in your handkerchief, or stick your watch into your pocket upside down, you use a memory device. Again, whenever you want to bear anything in mind you reduce difficulties and bring some kind of order into what you are trying to retain.

Thus, some artificial grip on the object is applied by everybody, and the utility and reliability of this grip determines the trustworthiness of a man's memory. This fact may be important for the criminal lawyer in two ways. On the one hand, it may help to clear up misunderstandings when false mnemonic has been applied. Thus, once somebody called an aniline dye, which is soluble in water and is called "nigrosin," by the name "moorosin," and asked for it under that name in the store. In order to aid his memory he had associated it with the word for black man = niger = negro = moor, and thus had substituted moor for nigro in the construction of the word he wanted. Again, somebody asked for the "Duke Salm" or the "Duke Schmier." The request was due to the fact that in the Austrian dialect salve is pronounced like salary and the colloquial for "salary" is "schmier" (to wipe). Dr. Ernst Lohsing tells me that he was once informed that a Mr. Schnepfe had called on him, while, as a matter of fact the gentleman's name was Wachtel. Such misunderstandings, produced by false mnemonic, may easily occur during the examination of witnesses. They are of profound significance. If once you suspect that false memory has been in play, you may arrive at the correct idea by using the proper synonyms and by considering similarly-pronounced words. If attention is paid to the determining conditions of the special case, success is almost inevitable.

The second way in which false mnemotechnique is important is that in which the technique was correct, but in which the key to the system has been lost, i. e., the witness has forgotten how he proceeded. Suppose, for example, that I need to recall the relation of the ages of three people to each other. Now, if I observe that M is the oldest, N the middle one, and O the youngest, I may suppose, in order to help my memory, that their births followed in the same order as their initials, M, N, O. Now suppose that at another time, in another case I observe the same relation but find the order of the initials reversed O N, M. If now, in the face of the facts, I stop simply with this technique, I may later on substitute the two cases for each other. Hence, when a witness says anything which appears to have been difficult to remember, it is necessary to ask him how he was able to remember it. If he assigns some aid to memory as the reason, he must be required to explain it, and he must not be believed unless it is found reliable. If the witness in the instance above, for example, says, "I never make use of converse relations," then his testimony will seem comparatively trustworthy. And it is not

difficult to judge the degree of reliability of any aid to memory whatever.

Great liars are frequently characterized by their easy use of the most complicated mnemotechnique. They know how much they need it.

Topic 7. THE WILL.

Section 57.

Of course, we do not intend to discuss here either the "will" of the philosopher, or the "malice" or "ill-will" of criminal law, nor yet the "freedom of the will" of the moralist. We aim only to consider a few facts that may be of significance to the criminal lawyer. Hence, we intend by "will" only what is currently and popularly meant. I take will to be the innereffect of the more powerful impulses, while action is the externaleffect of those impulses. When Hartmann says that will is the transposition of the ideal into the real, he sounds foolish, but in one sense the definition is excellent. You need only understand by ideal that which does not yet exist, and by real that which is a fact and actual. For when I voluntarily compel myself to think about some subject, something has actually happened, but this event is not "real" in the ordinary sense of that word. We are to bear in mind, however, that Locke warned us against the contrast between intelligence and will, as real, spiritual essences, one of which gives orders and the other of which obeys. From this conception many fruitless controversies and confusions have arisen. In this regard, we criminalists must always remember how often the common work of will and intelligence opposes us in witnesses and still more so in defendants, causing us great difficulties. When the latter deny their crime with iron fortitude and conceal their guilt by rage, or when for months they act out most difficult parts with wonderful energy, we must grant that they exhibit aspects of the will which have not yet been studied. Indeed, we can make surprising observations of how effectively prisoners control the muscles of their faces, which are least controllable by the will. The influence the will may have on a witness's power even to flush and grow pale is also more extensive than may be established scientifically. This can be learned from quite remote events. My son happens to have told me that at one time he found himself growing pale with cold, and as under the circumstance he was afraid of being accused of lacking courage to pursue his task, he tried with all his power to

suppress his pallor, and succeeded perfectly. Since then, at court, I have seen a rising blush or beginning pallor suppressed completely; yet this is theoretically impossible.

But the will is also significant in judging the man as a whole. According to Drobisch,[1] the abiding qualities and ruling "set" of a man's volition constitute his character. Not only inclination, and habits, and guiding principles determine the character, but also meanings, prejudices, convictions, etc. of all kinds. Since, then, we can not avoid studying the character of the individual, we must trace his volitions and desires. This in itself is not difficult; the idea of his character develops spontaneously when so traced. But the will contains also the characteristic signs of difference which are important for our purposes. We are enabled to work intelligently and clearly only by our capacity for distinguishing indifferent, from criminal and logically interpretable deeds. Nothing makes our work so difficult as the inconceivably superfluous mass of details. Not every deed or activity is an action; only those are such which are determined by will and knowledge. So Abegg[2] teaches us, what is determined by means of the will may be discovered by analysis.

Of course, we must find the proper approach to this subject and not get lost in the libertarian-deterministic quarrel, which is the turning-point in contemporary criminal law. Forty years ago Renan said that the error of the eighteenth century lay generally in assigning to the free and self-conscious will what could be explained by means of the natural effects of human powers and capacities. That century understood too little the theory of instinctive activity. Nobody will claim that in the transposition of willing into the expression of human capacity, the question of determinism is solved. The solution of this question is not our task. We do get an opening however through which we can approach the criminal,—not by having to examine the elusive character of his will, but by apprehending the intelligible expression of his capacity. The weight of our work is set on the application of the concept of causality, and the problem of free-will stands or falls with that.

Bois-Reymond in his "Limits of the Knowledge of Nature" has brought some clearness into this problem: "Freedom may be denied, pain and desire may not; the appetite which is the stimulus to action necessarily precedes sense-perception. The problem, therefore, is that of sense-perception, and not as I had said a minute

ago, that of the freedom of the will. It is to the former that analytic mechanics may be applied." And the study of sense-perception is just what we lawyers may be required to undertake.

Of course, it is insufficient merely to study the individual manifestations of human capacities, for these may be accidental results or phenomena, determined by unknown factors. Our task consists in attaining abstractions in accord with careful and conscientious perceptions, and in finding each determining occasion in its particular activities.

According to Drobisch, "maxims and the subjective principles of evolution are, as Kant calls them, laws of general content required to determine our own volitions and actions. Then again, they are rules of our own volition and action which we ourselves construct, and which hence are subjectively valid. When these maxims determine our future volitions and actions they are postulates." We may, therefore, say that we know a man when we know his will, and that we know his will when we know his maxims. By means of his maxims we are able to judge his actions.

But we must not reconstruct his maxims theoretically. We must study everything that surrounds, alters, and determines him, for it is at this point that a man's environments and relationships most influence him. As Grohmann said, half a century ago, "If you could find an elixir, which could cause the vital organs to work otherwise, if you could alter the somatic functions of the body, you would be the master of the will." Therefore it is never superfluous to study the individual's environmental conditions, surroundings, all his outer influences. That the effort required in such a study is great, is of course obvious, but the criminal lawyer must make it if he is to perform his task properly.[3]

Topic 8. EMOTION.

Section 58.

Little as emotion, as generally understood, may have to do with the criminalist, it is, in its intention, most important for him. The motive of a series of phenomena and events, both in prisoners and witnesses, is emotion. In what follows, therefore, we shall attempt to show that feeling, in so far as we need to consider it, need not be taken as an especial function. This is only so far significant as to

make our work easier by limiting it to fewer subjects. If we can reduce some one psychic function to another category we can explain many a thing even when we know only the latter. In any event, the study of a single category is simpler than that of many.[1]

Abstractly, the word emotion is the property or capacity of the mind to be influenced pleasantly or unpleasantly by sensations, perceptions, and ideas. Concretely, it means the conditions of desire or disgust which are developed by the complex of conditions thereby aroused. We have first to distinguish between the so-called animal and the higher emotions. We will assume that this distinction is incorrect, inasmuch as between these classes there is a series of feelings which may be counted as well with one as with the other, so that the transition is incidental and no strict differentiation is possible. We will, however, retain the distinction, as it is easier by means of it to pass from the simpler to the more difficult emotions. The indubitably animal passions we shall take to be hunger, thirst, cold, etc. These are first of all purely physiological stimuli which act on our body. But it is impossible to imagine one of them, without, at the same time, inevitably bringing in the idea of the defense against this physiological stimulus. It is impossible to think of the feeling of hunger without sensing also the strain to find relief from this feeling, for without this sensation hunger would not appear as such. If I am hungry I go for food; if I am cold I seek for warmth; if I feel pain I try to wipe it out. How to satisfy these desiderative actions is a problem for the understanding, whence it follows that successful satisfaction, intelligent or unintelligent, may vary in every possible degree. We see that the least intelligent—real cretins—sometimes are unable to satisfy their hunger, for when food is given the worst of them, they stuff it, in spite of acute sensations of hunger, into their ears and noses, but not into their mouths. We must therefore say that there is always a demand for a minimum quantity of intelligence in order to know that the feeling of hunger may be vanquished by putting food into the mouth.

One step further: In the description of the conduct of anthropoid apes which are kept in menageries, etc., especial intelligence is assigned to those who know how to draw a blanket over themselves as protection against cold. The same action is held to be a sign of intelligence in very young children.

Still more thoroughly graded is the attitude toward pain, inasmuch

as barely a trace of intelligence is required, in order to know that it is necessary to wipe away a hot liquid drop that has fallen on the body. Every physiological text-book mentions the fact that a decapitated frog makes such wiping movements when it is wet with acid. From this unconscious activity of the understanding to the technically highest-developed treatment of a burn, a whole series of progressively higher expressions of intelligence may be interpolated, a series so great as to defy counting.

Now take another, still animal, but more highly-developed feeling, for example, the feeling of comfort. We lay a cat on a soft bolster— she stretches herself, spreads and thins herself out, in order to bring as many nerve termini as possible into contact with the pleasant stimuli of the bolster. This behavior of the cat may be construed as instinctive, also as the aboriginal source of the sense of comfort and as leading to luxury in comfort, the stage of comfort which Roscher calls highest. (I. Luxury in eating and drinking. II. Luxury in dress. III. Luxury in comfort.)

Therefore we may say that the reaction of the understanding to the physiological stimulus aims to set it aside when it is unpleasant, and to increase and exhaust it when it is pleasant, and that in a certain sense both coincide (the ousting of unpleasant darkness is equivalent to the introduction of pleasant light). We may therefore say generally, that feeling is a physiological stimulus indivisibly connected with the understanding's sensitive attitude thereto. Of course there is a far cry from instinctive exclusion and inclusion to the most refined defensive preparation or interpretation, but the differences which lie next to each, on either side, are only differences in degree.

Now let us think of some so-called higher feeling and consider a special case of it. I meet for the first time a man who is unpleasantly marked, e. g., with badly colored hair. This stimulates my eyes disagreeably, and I seek either by looking away or by wishing the man away to protect myself from this physiologically-inimical influence, which already eliminates all feeling of friendship for this harmless individual. Now I see that the man is torturing an animal,—I do not like to see this, it affects me painfully; hence I wish him out of the way still more energetically. If he goes on so, adding one disagreeable characteristic to another, I might break his bones to stop him, bind him in chains to hinder him; I even might kill him, to save myself the unpleasant excitation he causes me. I strain my intelligence to think of some means of opposing him, and clearly, in

this case, also, physiological stimulus and activity of the understanding are invincibly united.

The emotion of anger is rather more difficult to explain. But it is not like suddenly-exploding hatred for it is acute, while hatred is chronic. I might be angry with my beloved child. But though at the moment of anger, the expression is identical with that of hatred, it is also transitive. In the extremest cases the negating action aims to destroy the stimulus. This is the most radical means of avoiding physiological excitation, and hence I tear in pieces a disagreeable letter, or stamp to powder the object on which I have hurt myself. Where persons are involved, I proceed either directly or symbolically when I can not, or may not, get my hands on the responsible one.

The case is the same with feeling of attraction. I own a dog, he has beautiful lines which are pleasant to my eye, he has a bell-like bark that stimulates my ear pleasantly, he has a soft coat which is pleasant to my stroking hand, I know that in case of need the dog will protect me (and that is a calming consideration), I know that he may be otherwise of use to me—in short my understanding tells me all kinds of pleasant things about the beast. Hence I like to have him near me; i. e., I like him. The same explanation may be applied to all emotions of inclination or repulsion. Everywhere we find the emotion as physiological stimulus in indivisible union with a number of partly known, partly unknown functions of the understanding. The unknown play an important rôle. They are serial understandings, i. e., inherited from remote ancestors, and are characterized by the fact that they lead us to do the things we do when we recognize intelligently any event and its requirements.

When one gets thirsty, he drinks. Cattle do the same. And they drink even when nobody has told them to, because this is an inherited action of countless years. If a man is, however, to proceed intelligently about his drinking, he will say, "By drying, or other forms of segregation, the water will be drawn from the cells of my body, they will become arid, and will no longer be sufficiently elastic to do their work. If, now, by way of my stomach, through endosmosis and exosmosis, I get them more water, the proper conditions will return." The consequences of this form of consideration will not be different from the instinctive action of the most elementary of animals—the wise man and the animal drink. So the whole content of every emotion is physiological stimulation and function of the understanding.

And what good is all this to the criminal lawyer? Nobody

doubts that both prisoners and witnesses are subject to the powerful influence of emotional expression. Nobody doubts that the determination, interpretation, and judgment of these expressions are as difficult as they are important to the judge. And when we consider these emotions as especial conditions of the mind it is indubitable that they are able to cause still greater difficulty because of their elusiveness, their very various intensity, and their confused effect. Once, however, we think of them as functions of the understanding, we have, in its activities, something better known, something rather more disciplined, which offers very many fewer difficulties in the judgment concerning the fixed form in which it acts. Hence, every judgment of an emotional state must be preceded by a reconstruction in terms of the implied functions of the understanding. Once this is done, further treatment is no longer difficult.

Topic 9. THE FORMS OF GIVING TESTIMONY.

Section 59.

Wherever we turn we face the absolute importance of language for our work. Whatever we hear or read concerning a crime is expressed in words, and everything perceived with the eye, or any other sense, must be clothed in words before it can be put to use. That the criminalist must know this first and most important means of understanding, completely and in all its refinements, is self-evident. But still more is required of him. He must first of all undertake a careful investigation of the essence of language itself. A glance over literature shows how the earliest scholars have aimed to study language with regard to its origins and character. Yet, who needs this knowledge? The lawyer. Other disciplines can find in it only a scientific interest, but it is practically and absolutely valuable only for us lawyers, who must, by means of language, take evidence, remember it, and variously interpret it. A failure in a proper understanding of language may give rise to false conceptions and the most serious of mistakes. Hence, nobody is so bound as the criminal lawyer to study the general character of language, and to familiarize himself with its force, nature, and development. Without this knowledge the lawyer may be able to make use of language, but failing to understand it, will slip up before the slightest difficulty. There is an exceedingly rich literature open to everybody.[1]

Section 60. (a) General Study of Variety in Forms of Expression.

Men being different in nature and bringing-up on the one hand, and language, being on the other, a living organism which varies with its soil, i. e., with the human individual who makes use of it, it is inevitable that each man should have especial and private forms of expression. These forms, if the man comes before us as witness or prisoner, we must study, each by itself. Fortunately, this study must be combined with another that it implies, i. e., the character and nature of the individual. The one without the other is unthinkable. Whoever aims to study a man's character must first of all attend to his ways of expression, inasmuch as these are most significant of a man's qualities, and most illuminating. A man is as he speaks. It is not possible, on the other hand, to study modes of expression in themselves. Their observation requires the study of a group of other conditions, if the form of speech is to be explained, or its analysis made even possible. Thus, one is involved in the other, and once you know clearly the tricks of speech belonging to an individual, you also have a clear conception of his character and conversely. This study requires, no doubt, considerable skill. But that is at the command of anybody who is devoted to the lawyer's task.

Tylor is correct in his assertion, that a man's speech indicates his origin much less than his bringing-up, his education, and his power. Much of this fact is due to the nature of language as a living growth and moving organism which acquires new and especial forms to express new and especial events in human life. Geiger[1] cites the following example of such changes in the meaning of words. "Mriga" means in Sanscrit, "wild beast;" in Zend it means merely "bird," and the equivalent Persian term "mrug" continues to mean only "bird," so that the barnyard fowls, song-birds, etc., are now called "mrug." Thus the first meaning, "wild animal" has been transmuted into its opposite, "tame animal." In other cases we may incorrectly suppose certain expressions to stand for certain things. We say, "to bake bread, to bake cake, to bake certain meats," and then again, "to roast apples, to roast potatoes, to roast certain meats." We should laugh if some foreigner told us that he had "roasted" bread.

These forms of expression have, as yet, no relation to character,

but they are the starting-point of quite characteristic modes which establish themselves in all corporations, groups, classes, such as students, soldiers, hunters, etc., as well as among the middle classes in large cities. Forms of this kind may become so significant that the use of a single one of them might put the user in question into jeopardy. I once saw two old gentlemen on a train who did not know each other. They fell into conversation and one told the other that he had seen an officer, while jumping from his horse, trip over his sword and fall. But instead of the word sword he made use of the old couleur-student slang word "speer," and the other old boy looked at him with shining eyes and cried out "Well, brother, what color?"

Still more remarkable is the mutation and addition of new words of especially definite meaning among certain classes. The words become more modern, like so much slang.

The especial use of certain forms is individual as well as social. Every person has his private usage. One makes use of "certainly," another of "yes, indeed," one prefers "dark," another "darkish." This fact has a double significance. Sometimes a man's giving a word a definite meaning may explain his whole nature. How heartless and raw is the statement of a doctor who is telling about a painful operation, "The patient sang!" In addition, it is frequently necessary to investigate the connotation people like to give certain words, otherwise misunderstandings are inevitable This investigation is, as a rule, not easy, for even when it is simple to bring out what is intended by an expression, it is still quite as simple to overlook the fact that people use peculiar expressions for ordinary things. This occurs particularly when people are led astray by the substitution of similars and by the repetition of such a substitution. Very few persons are able to distinguish between identity and similarity; most of them take these two characters to be equivalent. If A and B are otherwise identical, save that B is a little bigger, so that they appear similar, there is no great mistake if I hold them to be equivalent and substitute B for A. Now I compare B with C, C with D, D with E, etc., and each member of the series is progressively bigger than its predecessor. If now I continue to repeat my first mistake, I have in the end substituted for A the enormously bigger E and the mistake has become a very notable one. I certainly would not have substituted E for A at the beginning, but the repeated substitution of similars has led me to this complete incommensurability.

Such substitutions occur frequently during the alterations of meanings, and if you wish to see how some remarkable signification of a term has arisen you will generally find it as a progression through gradually remoter similarities to complete dissimilarity. All such extraordinary alterations which a word has undergone in the course of long usage, and for which each linguistic text-book contains numerous examples, may, however, develop with comparative speed in each individual speaker, and if the development is not traced may lead, in the law-court, to very serious misunderstandings.

Substitutions, and hence, sudden alterations, occur when the material of language, especially in primitive tongues, contains only simple differentiations. So Tylor mentions the fact, that the language of the West African Wolofs contains the word "dágou," to go, "dágou," to stride proudly; "dágana," to beg dejectedly; "dagána," to demand. The Mpongwes say, "mì tonda," I love, and "mi tônda," I do not love. Such differentiations in tone our own people make also, and the mutation of meaning is very close. But who observes it at all?

Important as are the changes in the meanings of words, they fall short beside the changes of meaning of the conception given in the mode of exposition. Hence, there are still greater mistakes, because a single error is neither easily noticeable nor traceable. J. S. Mill says, justly, that the ancient scientists missed a great deal because they were guided by linguistic classification. It scarcely occurred to them that what they assigned abstract names to really consisted of several phenomena. Nevertheless, the mistake has been inherited, and people who nowadays name abstract things, conceive, according to their intelligence, now this and now that phenomenon by means of it. Then they wonder at the other fellow's not understanding them. The situation being so, the criminalist is coercively required, whenever anything abstract is named, first of all to determine accurately what the interlocutor means by his word. In these cases we make the curious discovery that such determination is most necessary among people who have studied the object profoundly, for a technical language arises with just the persons who have dealt especially with any one subject.

As a rule it must be maintained that time, even a little time, makes an essential difference in the conception of any object. Mittermaier, and indeed Bentham, have shown what an influence the interval between observation and announcement exercises on the form of exposition. The witness who is immediately examined may,

perhaps, say the same thing that he would say several weeks after— but his presentation is different, he uses different words, he understands by the different words different concepts, and so his testimony becomes altered.

A similar effect may be brought about by the conditions under which the evidence is given. Every one of us knows what surprising differences occur between the statements of the witness made in the silent office of the examining justice and his secretary, and what he says in the open trial before the jury. There is frequently an inclination to attack angrily the witnesses who make such divergent statements. Yet more accurate observation would show that the testimony is essentially the same as the former but that the manner of giving it is different, and hence the apparently different story. The difference between the members of the audience has a powerful influence. It is generally true that reproductive construction is intensified by the sight of a larger number of attentive hearers, but this is not without exception. In the words "attentive hearers" there is the notion that the speaker is speaking interestingly and well, for otherwise his hearers would not be attentive, and if anything is well done and is known to be well done, the number of the listeners is exciting, inasmuch as each listener is reckoned as a stimulating admirer. This is invariably the case. If anybody is doing a piece of work under observation he will feel pleasant when he knows that he is doing it well, but he will feel disturbed and troubled if he is certain of his lack of skill. So we may grant that a large number of listeners increases reproductive constructivity, but only when the speaker is certain of his subject and of the favor of his auditors. Of the latter, strained attention is not always evidence. When a scholar is speaking of some subject chosen by himself, and his audience listens to him attentively, he has chosen his subject fortunately, and speaks well; the attention acts as a spur, he speaks still better, etc. But this changes when, in the course of a great trial which excites general interest, the witness for the government appears. Strained attention will also be the rule, but it does not apply to him, it applies to the subject. He has not chosen his topic, and no recognition for it is due him—it is indifferent to him whether he speaks ill or well. The interest belongs only to the subject, and the speaker himself receives, perhaps, the undivided antipathy, hatred, disgust, or scorn, of all the listeners. Nevertheless, attention is intense and strained, and inasmuch as the speaker knows that this does not pertain to him or his merits, it confuses and depresses him.

It is for this reason that so many criminal trials turn out quite contrary to expectation. Those who have seen the trial only, and were not at the prior examination, understand the result still less when they are told that "nothing" has altered since the prior examination—and yet much has altered; the witnesses, excited or frightened by the crowd of listeners, have spoken and expressed themselves otherwise than before until, in this manner, the whole case has become different.

In a similar fashion, some fact may be shown in another light by the manner of narration used by a particular witness. Take, as example, some energetically influential quality like humor. It is self-evident that joke, witticism, comedy, are excluded from the court-room, but if somebody has actually introduced real, genuine humor by way of the dry form of his testimony, without having crossed in a single word the permissible limit, he may, not rarely, narrate a very serious story so as to reduce its dangerous aspect to a minimum. Frequently the testimony of some funny witness makes the rounds of all the newspapers for the pleasure of their readers. Everybody knows how a really humorous person may so narrate experiences, doubtful situations of his student days, unpleasant traveling experiences, difficult positions in quarrels, etc., that every listener must laugh. At the same time, the events told of were troublesome, difficult, even quite dangerous. The narrator does not in the least lie, but he manages to give his story the twist that even the victim of the situation is glad to laugh at.[2] As Kräpelin says, "The task of humor is to rob a large portion of human misfortune of its wounding power. It does so by presenting to us, with our fellows as samples, the comedy of the innumerable stupidities of human life."

Now suppose that a really humorous witness tells a story which involves very considerable consequences, but which he does not really end with tragic conclusions. Suppose the subject to be a great brawl, some really crass deception, some story of an attack on honor, etc. The attitude toward the event is altered with one turn, even though it would seem to have been generated progressively by ten preceding witnesses and the new view of the matter makes itself valid at least mildly in the delivery of the sentence. Then whoever has not heard the whole story understands the results least of all.

In the same way we see really harmless events turned into tragedies

by the testimony of a black-visioned, melancholy witness, without his having used, in this case or any other, a single untrue word. In like manner the bitterness of a witness who considers his personal experiences to be generally true, may color and determine the attitude of some, not at all serious, event. Nor is this exaggeration. Every man of experience will, if he is only honest enough, confirm the fact, and grant that he himself was among those whose attitude has been so altered; I avoid the expression—"duped."

It is necessary here, also, to repeat that the movements of the hands and other gestures of the witnesses while making their statements will help much to keep the correct balance. Movements lie much less frequently than words.[3]

Another means of discovering whether a witness is not seduced by his attitude and his own qualities is the careful observation of the impression his narrative makes on himself. Stricker has controlled the conditions of speech and has observed that so long as he continued to bring clearly described complexes into a causal relation, satisfactory to him, he could excite his auditors; as soon as he spoke of a relation which did not satisfy him the attitude of the audience altered. We must invert this observation; we are the auditors of the witness and must observe whether his own causal connections satisfy him. So long as this is the case, we believe him. When it fails to be so he is either lying, or he himself knows that he is not expressing himself as he ought to make us correctly understand what he is talking about.

Section 61. (b) Dialect Forms.

What every criminal lawyer must unconditionally know is the dialect of those people he has most to deal with. This is so important that I should hold it conscienceless to engage in the profession of criminology without knowing the dialects. Nobody with experience would dispute my assertion that nothing is the cause of so great and so serious misunderstandings, of even inversions of justice, as ignorance of dialects, ignorance of the manner of expression of human groups. Wrongs so caused can never be rectified because their primary falsehood starts in the protocol, where no denial, no dispute and redefinition can change them.

It is no great difficulty to learn dialects, if only one is not seduced

by comic pride and foolish ignorance of his own advantage into believing that popular speech is something low or common. Dialect has as many rights as literary language, is as living and interesting an organism as the most developed form of expression. Once the interest in dialect is awakened, all that is required is the learning of a number of meanings. Otherwise, there are no difficulties, for the form of speech of the real peasant (and this is true all over the world), is always the simplest, the most natural, and the briefest. Tricks, difficult construction, circumlocutions are unknown to the peasant, and if he is only left to himself he makes everything definite, clear, and easily intelligible.

There are many more difficulties in the forms of expression of the uncultivated city man, who has snapped up a number of uncomprehended phrases and tries to make use of them because of their suppositious beauty, regardless of their fitness. Unpleasant as it is to hear such a screwed and twisted series of phrases, without beginning and without end, it is equally difficult to get a dear notion of what the man wanted to say, and especially whether the phrases used were really brought out with some purpose or simply for the sake of showing off, because they sound "educated."

In this direction nothing is more significant than the use of the imperfect in countries where its use is not customary and where as a rule only the perfect is used; not "I was going," but "I have gone" (went). In part the reading of newspapers, but partly also the unfortunate habit of our school teachers, compel children to the use of the imperfect, which has not an iota more justification than the perfect, and which people make use of under certain circumstances, i. e., when they are talking to educated people, and then only before they have reached a certain age.

I confess that I regularly mistrust a witness who makes use of an imperfect or some other form not habitual to him. I presuppose that he is a weak-minded person who has allowed himself to be persuaded; I believe that he is not altogether reliable because he permits untrue forms to express his meaning, and I fear that he neglects the content for the sake of the form. The simple person who quietly and without shame makes use of his natural dialect, supplies no ground for mistrust.

There are a few traits of usage which must always be watched. First of all, all dialects are in certain directions poorer than the literary language. E. g., they make use of fewer colors. The blue grape, the red wine, may be indicated by the word black, the light

wine by the word white. Literary language has adopted the last term from dialect. Nobody says water-colored or yellow wine, although nobody has ever yet seen white wine. Similarly, no peasant says a "brown dog," a "brown-yellow cow"—these colors are always denoted by the word red. This is important in the description of clothes. There is, however, no contradiction between this trait and the fact that the dialect may be rich in terms denoting objects that may be very useful, e. g. the handle of a tool may be called handle, grasp, heft, stick, clasp, etc.

When foreign words are used it is necessary to observe in what tendency, and what meaning their adoption embodies.[1]

The great difficulty of getting uneducated people to give their testimony in direct discourse is remarkable. You might ask for the words of the speaker ten times and you always hear, "He told me, I should enter," you never hear "He told me, `Go in.' " This is to be explained by the fact, already mentioned, that people bear in mind only the meaning of what they have heard. When the question of the actual words is raised, the sole way to conquer this disagreeable tendency is to develop dialogue and to say to the witness, "Now you are A and I am B; how did it happen?" But even this device may fail, and when you finally do compel direct quotation, you can not be certain of its reliability, for it was too extraordinary for the witness to quote directly, and the extraordinary and unhabitual is always unsafe.

What especially wants consideration in the real peasant is his silence. I do not know whether the reasons for the silence of the countrymen all the world over have ever been sought, but a gossiping peasant is rare to find. This trait is unfortunately exhibited in the latter's failure to defend himself when we make use of energetic investigation. It is said that not to defend yourself is to show courage, and this may, indeed, be a kind of nobility, a disgust at the accusation, or certainty of innocence, but frequently it is mere incapacity to speak, and inexperienced judges may regard it as an expression of cunning or conviction. It is wise therefore, in this connection, not to be in too great a hurry, and to seek to understand clearly the nature of the silent person. If we become convinced that the latter is by nature uncommunicative, we must not wonder that he does not speak, even when words appear to be quite necessary.

In certain cases uneducated people must be studied from the same

point of view as children. Geiger[2] speaks of a child who knew only one boy, and all the other boys were Otho to him because this first boy was called Otho. So the recruit at the Rhine believed that in his country the Rhine was called Donau. The child and the uneducated person can not subordinate things under higher concepts. Every painted square might be a bon-bon, and every painted circle a plate. New things receive the names of old ones. And frequently the skill of the criminalists consists in deriving important material from apparently worthless statements, by way of discovering the proper significance of simple, inartistic, but in most cases excellently definitive images. It is of course self-evident that one must absolutely refrain from trickery.

Section 62. (c) Incorrect Forms of Expression.

If it is true that by the earnest and repeated study of the meanings of words we are likely to find them in the end containing much deeper sense and content than at the beginning, we are compelled to wonder that people are able to understand each other at all. For if words do not have that meaning which is obvious in their essential denotation, every one who uses them supplies according to his inclination, and status the "deeper and richer sense." As a matter of fact many more words are used pictorially than we are inclined to think. Choose at random, and you find surprisingly numerous words with exaggerated denotations. If I say, "I posit the case, I press through, I jump over, the proposition, etc.," these phrases are all pictures, for I have posited nothing, I have pressed through no obstacle, and have jumped over no object. My words, therefore, have not stood for anything real, but for an image, and it is impossible to determine the remoteness of the latter from the former, or the variety of direction and extent this remoteness may receive from each individual. Wherever images are made use of, therefore, we must, if we are to know what is meant, first establish how and where the use occurred. How frequently we hear, e. g., of a "four-cornered" table instead of a square table; a "very average" man, instead of a man who is far below the average. In many cases this false expression is half-consciously made for the purpose of beautifying a request or making it appear more modest. The smoker says: "May I have some light," although you know that it is perfectly indifferent whether much or

little light is taken from the cigar. "May I have just a little piece of roast," is said in order to make the request that the other fellow should pass the heavy platter seem more modest. And again: "Please give me a little water," does not modify the fact that the other fellow must pass the whole water flask, and that it is indifferent to him whether afterwards you take much or little water. So, frequently, we speak of borrowing or lending, without in the remotest thinking of returning. The student says to his comrade, "Lend me a pen, some paper, or some ink," but he has not at all any intention of giving them back. Similar things are to be discovered in accused or witnesses who think they have not behaved properly, and who then want to exhibit their misconduct in the most favorable light. These beautifications frequently go so far and may be made so skilfully that the correct situation may not be observed for a long time. Habitual usage offers, in this case also, the best examples. For years uncountable it has been called a cruel job to earn your living honestly and to satisfy the absolute needs of many people by quickly and painlessly slaughtering cattle. But, when somebody, just for the sake of killing time, because of ennui, shoots and martyrs harmless animals, or merely so wounds them that if they are not retrieved they must die terrible deaths, we call it noble sport. I should like to see a demonstration of the difference between killing an ox and shooting a stag. The latter does not require even superior skill, for it is much more difficult to kill an ox swiftly and painlessly than to shoot a stag badly, and even the most accurate shot requires less training than the correct slaughter of an ox. Moreover, it requires much more courage to finish a wild ox than to destroy a tame and kindly pheasant. But usage, once and for all, has assumed this essential distinction between men, and frequently this distinction is effective in criminal law, without our really seeing how or why. The situation is similar in the difference between cheating in a horse trade and cheating about other commodities. It occurs in the distinction between two duellists fighting according to rule and two peasant lads brawling with the handles of their picks according to agreement. It recurs again in the violation of the law by somebody "nobly inspired with champagne," as against its violation by some "mere" drunkard. But usage has a favoring, excusing intent for the first series, and an accusing, rejecting intent for the latter series. The different points of view from which various events are seen are the consequence of the varieties of the usage which first distinguished the view-points from one another.

There is, moreover, a certain dishonesty in speaking and in listening where the speaker knows that the hearer is hearing a different matter, and the hearer knows that the speaker is speaking a different matter. As Steinthal[1] has said, "While the speaker speaks about things that he does not believe, and the reality of which he takes no stock in, his auditor, at the same time, knows right well what the former has said; he understands correctly and does not blame the speaker for having expressed himself altogether unintelligibly." This occurs very frequently in daily routine, without causing much difficulty in human intercourse, but it ought, for this reason, to occur inversely in our conversation with witnesses and accused. I know that the manner of speaking just described is frequently used when a witness wants to clothe some definite suspicion without expressing it explicitly. In such cases, e. g., the examiner as well as the witness believes that X is the criminal. For some reason, perhaps because X is a close relation of the witness or of "the man higher up," neither of them, judge nor witness, wishes to utter the truth openly, and so they feel round the subject for an interminable time. If now, both think the same thing, there results at most only a loss of time, but no other misfortune. When, however, each thinks of a different object, e. g., each thinks of another criminal, but each believes mistakenly that he agrees with the other, their separating without having made explicit what they think, may lead to harmful misunderstandings. If the examiner then believes that the witness agrees with him and proceeds upon this only apparently certain basis, the case may become very bad. The results are the same when a confession is discussed with a suspect, i. e., when the judge thinks that the suspect would like to confess, but only suggests confession, while the latter has never even thought of it. The one thing alone our work permits of is open and clear speaking; any confused form of expression is evil.

Nevertheless, confusions often occur involuntarily, and as they can not be avoided they must be understood. Thus, it is characteristic to understand something unknown in terms of some known example, i. e., the Romans who first saw an elephant, called it "bos lucani." Similarly "wood-dog" = wolf; "sea-cat" = monkey, etc. These are forms of common usage, but every individual is accustomed to make such identifications whenever he meets with any strange object. He speaks, therefore, to some degree in images,

and if his auditor is not aware of the fact he can not understand him. His speaking so may be discovered by seeking out clearly whether and what things were new and foreign to the speaker. When this is learned it may be assumed that he will express himself in images when considering the unfamiliar object. Then it will not be difficult to discover the nature and source of the images.

Similar difficulties arise with the usage of foreign terms. It is of course familiar that their incorrect use is not confined to the uneducated. I have in mind particularly the weakening of the meaning in our own language. The foreign word, according to Volkmar, gets its significance by robbing the homonymous native word of its definiteness and freshness, and is therefore sought out by all persons who are unwilling to call things by their right names. The "triste position" is far from being so sad as the "sad" position. I should like to know how a great many people could speak, if they were not permitted to say malheur, méchant, perfide, etc.—words by means of which they reduce the values of the terms at least a degree in intensity of meaning. The reason for the use of these words is not always the unwillingness of the speaker to make use of the right term, but really because it is necessary to indicate various degrees of intensity for the same thing without making use of attributes or other extensions of the term. Thus the foreign word is in some degree introduced as a technical expression. The direction in which the native word weakens, however, taken as that is intended by the individual who uses its substitute, is in no sense universally fixated. The matter is entirely one of individual usage and must be examined afresh in each particular case.

The striving for abbreviated forms of expression,—extraordinary enough in our gossipy times,—manifests itself in still another direction. On my table, e. g., there is an old family journal, "From Cliff to Sea." What should the title mean? Obviously the spatial distribution of the subject of its contents and its subscribers—i. e., "round about the whole earth," or "Concerning all lands and all peoples." But such titles would be too long; hence, they are synthesized into, "From Cliff to Sea," without the consideration that cliffs often stand right at the edge of the sea, so that the distance between them may be only the thickness of a hair:—cliff and sea are not local opposites.

Or: my son enters and tells me a story about an "old semester." By "old semester" he means an old student who has spent many terms, at least more than are required or necessary, at the university.

As this explanation is too long, the whole complex is contracted into "old semester," which is comfortable, but unintelligible to all people not associated with the university. These abbreviations are much more numerous than, as a rule, they are supposed to be, and must always be explained if errors are to be avoided. Nor are silent and monosyllabic persons responsible for them; gossipy individuals seek, by the use of them, to exhibit a certain power of speech. Nor is it indifferent to expression when people in an apparently nowise comfortable fashion give approximate circumlocutive figures, e. g., half-a-dozen, four syllables, instead of the monosyllable six; or "the bell in the dome at St. Stephen's has as many nicks as the year has days," etc. It must be assumed that these circumlocutive expressions are chosen, either because of the desire to make an assertion general, or because of the desire for some mnemonic aid. It is necessary to be cautious with such statements, either because, as made, they only "round out" the figures or because the reliability of the aid to memory must first be tested. Finally, it is well-known that foreign words are often changed into senseless words of a similar sound. When such unintelligible words are heard, very loud repeated restatement of the word will help in finding the original.
