Section 18. (5) Reflex Movements.

Reflex actions are also of greater significance than as a rule they are supposed to be. According to Lotze,[1] "reflex actions are not

limited to habitual and insignificant affairs of the daily life. Even compounded series of actions which enclose the content even of a crime may come to actuality in this way . . . in a single moment in which the sufficient opposition of some other emotional condition, the enduring intensity of emotion directed against an obstacle, or the clearness of a moving series of ideas is lacking. The deed may emerge from the image of itself without being caused or accompanied by any resolve of the doer. Hearings of criminals are full of statements which point to such a realization of their crimes, and these are often considered self-exculpating inventions, inasmuch as people fear from their truth a disturbance or upsetting of the notions concerning adjudication and actionability. The mere recognition of that psychological fact alters the conventional judgment but little; the failure in these cases consists in not having prevented that automatic transition of images into actions, a transition essentially natural to our organism which ought, however, like so many other things, to be subjected to power of the will." Reflex movements require closer study.[2] The most numerous and generally known are: dropping the eyelids, coughing, sneezing, swallowing, all involuntary actions against approaching or falling bodies; then again the patellar reflex and the kremaster reflex, etc. Other movements of the same kind were once known and so often practiced that they became involuntary.[3] Hence, for example, the foolish question how a person believed to be disguised can be recognized as man or woman. The well known answer is: let some small object fall on his lap; the woman will spread her limbs apart because she is accustomed to wear a dress in which she catches the object; the man will bring his limbs together because he wears trousers and is able to catch the object only in this way. There are so many such habitual actions that it is difficult to say where actual reflexes end and habits begin. They will be properly distinguished when the first are understood as single detached movements and the last as a continuous, perhaps even unconscious and long-enduring action. When I, for example, while working, take a cigar, cut off the end, light it, smoke, and later am absolutely unaware that I have done this, what has occurred is certainly not a reflex but a habitual action. The latter does not belong to this class in which are to be grouped only such as practically bear a defensive character. As examples of how such movements may have criminological significance only one's own experience may be cited because it is so difficult to put oneself at the point of view of another. I want to consider two such examples. One evening I passed through an unfrequented street and came upon an inn just at the moment that an intoxicated fellow was thrown out, and directly upon me. At the very instant I hit the poor fellow a hard blow on the ear. I regretted the deed immediately, the more so as the assaulted man bemoaned his misfortune, "inside they throw him out, outside they box his ears." Suppose that I had at that time burst the man's ear-drum or otherwise damaged him heavily. It would have been a criminal matter and I doubt whether anybody would have believed that it was a "reflex action," though I was then, as to-day, convinced that the action was reflex. I didn't in the least know what was going to happen to me and what I should do. I simply noticed that something unfriendly was approaching and I met it with a defensive action in the form of an uppercut on the ear. What properly occurred I knew only when I heard the blow and felt the concussion of my hand. Something similar happened to me when I was a student. I had gone into the country hunting before dawn, when some one hundred paces from the house, right opposite me a great ball rolled down a narrow way. Without knowing what it was or why I did it I hit at the ball heavily with an alpenstock I carried in my hand, and the thing emerged as two fighting tomcats with teeth fixed in each other. One of them was my beloved possession, so that I keenly regretted the deed, but even here I had not acted consciously; I had simply smashed away because something unknown was approaching me. If I had then done the greatest damage I could not have been held responsible— if my explanation were allowed; but that it would have been allowed I do not believe in this case, either.

A closer examination of reflex action requires consideration of certain properties, which in themselves cannot easily have criminal significance, but which tend to make that significance clearer. One is the circumstance that there are reflexes which work while you sleep. That we do not excrete during sleep depends on the fact that the faeces pressing in the large intestine generates a reflexive action of the constrictors of the rectum. They can be brought to relax only through especially powerful pressure or through the voluntary relaxation of one's own constrictors.

The second suggestive circumstance is the fact that even habitual reflexes may under certain conditions, especially when a particularly weighty different impression comes at the same time, not

take place. It is a reflex, for example, to withdraw the hand when it feels pain, in spite of the fact that one is so absorbed with another matter as to be unaware of the whole process; but if interest in this other matter is so sufficiently fixed as to make one forget, as the saying goes, the whole outer world, the outer impression of pain must have been very intense in order to awaken its proper reflex. The attention may, however, not be disturbed at all and yet the reflex may fail. If we suppose that a reflex action is one brought about through the excitement of an afferent sensory nerve which receives the stimulation and brings it to the center from which the excitement is transferred to the motor series (Landois[4]), we exclude the activity of the brain. But this exclusion deals only with conscious activity and the direct transition through the reflex center can happen successfully only because the brain has been consciously at work innumerable times, so that it is coöperating in the later cases also without our knowing it. When, however, the brain is brought into play through some other particularly intense stimuli, it is unable to contribute that unconscious coöperation and hence the reflex action is not performed. On this point I have, I believe, an instructive and evidential example. One of my maids opened a match-box pasted with paper at the corner by tearing the paper along the length of the box with her thumb-nail. Apparently the box was over-filled or the action was too rapidly made, for the matches flamed up explosively and the whole box was set on fire. What was notable was the fact that the girl threw the box away neither consciously nor instinctively; she shrieked with fright and kept the box in her hand. At her cry my son rushed in from another room, and only after he had shouted as loudly as possible, "Throw it away, drop it," did she do so. She had kept the burning thing in her hand long enough to permit my son to pass from one room into another, and her wound was so serious that it needed medical treatment for weeks. When asked why she kept the burning box in her hand in spite of really very terrible pain she simply declared that "she didn't think of it," though she added that when she was told to throw the thing away it just occurred to her that that would be the wisest of all things to do. What happened then was obviously this: fear and pain so completely absorbed the activity of the brain that it was not only impossible for it consciously to do the right thing, it was even unable to assist in the unconscious execution of the reflex.

This fact suggests that the sole activity of the spinal cord does not suffice for reflexes, since if it did, those would occur even when the brain is otherwise profoundly engaged. As they do not so occur the brain also must be in play. Now this distinction is not indifferent for us; for if we hold that the brain acts during reflexes we have to grant the possibility of degrees in its action. Thus where brain activity is in question, the problem of responsibility also arises, and we must hold that wherever a reflex may be accepted as the cause of a crime the subject of the degree of punishment must be taken exceptionally into account. It is further to be noted that as a matter of official consideration the problem of the presence of reflexes ought to be studied, since it rarely occurs that a man says, "It was purely a reflex action." He says, perhaps, "I don't know how it happened," or, "I couldn't do otherwise," or he denies the whole event because he really was not aware how it happened. That the questions are here difficult, both with regard to the taking of evidence, and with regard to the judgment of guilt, is obvious,— and it is therefore indifferent whether we speak of deficiency in inhibition-centers or of ill-will[5] and malice.
