CHAPTER XVII
SCIENCE IN THE COURSE OF STUDY:
1. The Logical and the Psychological.
—By science is meant, as already stated, that knowledge which is
the outcome of methods of observation, reflection, and testing which
are deliberately adopted to secure a settled, assured subject matter.
It involves an intelligent and persistent endeavor to revise current
beliefs so as to weed out what is erroneous, to add to their accuracy,
and, above all, to give them such shape that the dependencies of the
various facts upon one another may be as obvious as possible. It is,
like all knowledge, an outcome of activity bringing about certain
changes in the environment. But in its case, the quality of the
resulting knowledge is the controlling factor and not an incident of the
activity. Both logically and educationally, science is the perfecting
of knowing, its last stage.
Science, in short, signifies a realization of the logical
implications of any knowledge. Logical order is not a form imposed upon
what is known; it is the proper form of knowledge as perfected. For it
means that the statement of subject matter is of a nature to exhibit to
one who understands it the premises from which it follows and the
conclusions to which it points
(See ante, p. 224).
As from a few bones the competent zoölogist reconstructs an animal;
so from the form of a statement in mathematics or physics the specialist
in the subject can form an idea of the system of truths in which it has
its place.
To the non-expert, however, this perfected form is a stumbling block.
Just because the material is stated with reference to the furtherance of
knowledge as an end in itself, its connections with the material of
everyday life are hidden. To the layman the bones are a mere curiosity.
Until he had mastered the principles of zoology, his efforts to make
anything out of them would be random and blind. From the standpoint of
the learner scientific form is an ideal to be achieved, not a starting
point from which to set out. It is, nevertheless, a frequent practice
to start in instruction with the rudiments of science somewhat
simplified. The necessary consequence is an isolation of science from
significant experience. The pupil learns symbols without the key to
their meaning. He acquires a technical body of information without
ability to trace its connections with the objects and operations with
which he is familiar—often he acquires simply a peculiar
vocabulary.
There is a strong temptation to assume that presenting subject matter in
its perfected form provides a royal road to learning. What more natural
than to suppose that the immature can be saved time and energy, and be
protected from needless error by commencing where competent inquirers
have left off? The outcome is written large in the history of education.
Pupils begin their study of science with texts in which the subject is
organized into topics according to the order of the specialist.
Technical concepts, with their definitions, are introduced at the
outset. Laws are introduced at a very early stage, with at best a few
indications of the way in which they were arrived at. The pupils learn
a "science" instead of learning the scientific way of treating the
familiar material of ordinary experience. The method of the advanced
student dominates college teaching; the approach of the college is
transferred into the high school, and so down the line, with such
omissions as may make the subject easier.
The chronological method which begins with the experience of the learner
and develops from that the proper modes of scientific treatment is often
called the "psychological" method in distinction from the logical method
of the expert or specialist. The apparent loss of time involved is more
than made up for by the superior understanding and vital interest
secured. What the pupil learns he at least understands. Moreover by
following, in connection with problems selected from the material of
ordinary acquaintance, the methods by which scientific men have reached
their perfected knowledge, he gains independent power to deal with
material within his range, and avoids the mental confusion and
intellectual distaste attendant upon studying matter whose meaning is
only symbolic. Since the mass of pupils are never going to become
scientific specialists, it is much more important that they should get
some insight into what scientific method means than that they should
copy at long range and second hand the results which scientific men have
reached. Students will not go so far, perhaps, in the "ground covered,"
but they will be sure and intelligent as far as they do go. And it is
safe to say that the few who go on to be scientific experts will have a
better preparation than if they had been swamped with a large mass of
purely technical and symbolically stated information. In fact, those
who do become successful men of science are those who by their own power
manage to avoid the pitfalls of a traditional scholastic introduction
into it.
The contrast between the expectations of the men who a generation or two
ago strove, against great odds, to secure a place for science in
education, and the result generally achieved is painful. Herbert
Spencer, inquiring what knowledge is of most worth, concluded that from
all points of view scientific knowledge is most valuable. But his
argument unconsciously assumed that scientific knowledge could be
communicated in a ready-made form. Passing over the methods by which
the subject matter of our ordinary activities is transmuted into
scientific form, it ignored the method by which alone science is
science. Instruction has too often proceeded upon an analogous plan.
But there is no magic attached to material stated in technically correct
scientific form. When learned in this condition it remains a body of
inert information. Moreover its form of statement removes it further
from fruitful contact with everyday experiences than does the mode of
statement proper to literature. Nevertheless that the claims made for
instruction in science were unjustifiable does not follow. For material
so taught is not science to the pupil.
Contact with things and laboratory exercises, while a great improvement
upon textbooks arranged upon the deductive plan, do not of themselves
suffice to meet the need. While they are an indispensable portion of
scientific method, they do not as a matter of course constitute
scientific method. Physical materials may be manipulated with
scientific apparatus, but the materials may be disassociated in
themselves and in the ways in which they are handled, from the materials
and processes used out of school. The problems dealt with may be only
problems of science: problems, that is, which would occur to one already
initiated in the science of the subject. Our attention may be devoted
to getting skill in technical manipulation without reference to the
connection of laboratory exercises with a problem belonging to subject
matter. There is sometimes a ritual of laboratory instruction as well
as of heathen religion.
[11]
It has been mentioned, incidentally, that scientific statements, or
logical form, implies the use of signs or symbols. The statement
applies, of course, to all use of language. But in the vernacular, the
mind proceeds directly from the symbol to the thing signified.
Association with familiar material is so close that the mind does not
pause upon the sign. The signs are intended only to stand for things
and acts. But scientific terminology has an additional use. It is
designed, as we have seen, not to stand for the things directly in their
practical use in experience, but for the things placed in a cognitive
system. Ultimately, of course, they denote the things of our common
sense acquaintance. But immediately they do not designate them in their
common context, but translated into terms of scientific inquiry. Atoms,
molecules, chemical formulæ, the mathematical propositions in the study
of physics—all these have primarily an intellectual value and only
indirectly an empirical value. They represent instruments for the
carrying on of science. As in the case of other tools, their
significance can be learned only by use. We cannot procure
understanding of their meaning by pointing to things, but only by
pointing to their work when they are employed as part of the technique
of knowledge.
Even the circle, square, etc., of geometry exhibit a difference from the
squares and circles of familiar acquaintance, and the further one
proceeds in mathematical science the greater the remoteness from the
everyday empirical thing. Qualities which do not count for the pursuit
of knowledge about spatial relations are left out; those which are
important for this purpose are accentuated. If one carries his study
far enough, he will find even the properties which are significant for
spatial knowledge giving way to those which facilitate knowledge of
other things—perhaps a knowledge of the general relations of
number. There will be nothing in the conceptual definitions even to
suggest spatial form, size, or direction. This does not mean that they
are unreal mental inventions, but it indicates that direct physical
qualities have been transmuted into tools for a special end—the
end of intellectual organization. In every machine the primary state of
material has been modified by subordinating it to use for a purpose.
Not the stuff in its original form but in its adaptation to an end is
important. No one would have a knowledge of a machine who could
enumerate all the materials entering into its structure, but only he who
knew their uses and could tell why they are employed as they are.
In like fashion one has a knowledge of mathematical conceptions only
when he sees the problems in which they function and their specific
utility in dealing with these problems. "Knowing" the definitions,
rules, formulæ, etc., is like knowing the names of parts of a machine
without knowing what they do. In one case, as in the other, the
meaning, or intellectual content, is what the element accomplishes in
the system of which it is a member.
2. Science and Social Progress.
—Assuming that the development of the direct knowledge gained in
occupations of social interest is carried to a perfected logical form,
the question arises as to its place in experience. In general, the
reply is that science marks the emancipation of mind from devotion to
customary purposes and makes possible the systematic pursuit of new
ends. It is the agency of progress in action. Progress is sometimes
thought of as consisting in getting nearer to ends already sought. But
this is a minor form of progress, for it requires only improvement of
the means of action or technical advance. More important modes of
progress consist in enriching prior purposes and in forming new ones.
Desires are not a fixed quantity, nor does progress mean only an
increased amount of satisfaction. With increased culture and new
mastery of nature, new desires, demands for new qualities of
satisfaction, show themselves, for intelligence perceives new
possibilities of action. This projection of new possibilities leads to
search for new means of execution, and progress takes place; while the
discovery of objects not already used leads to suggestion of new ends.
That science is the chief means of perfecting control of means of action
is witnessed by the great crop of inventions which followed intellectual
command of the secrets of nature. The wonderful transformation of
production and distribution known as the industrial revolution is the
fruit of experimental science. Railways, steamboats, electric motors,
telephone and telegraph, automobiles, aeroplanes and dirigibles are
conspicuous evidences of the application of science in life. But none
of them would be of much importance without the thousands of less
sensational inventions by means of which natural science has been
rendered tributary to our daily life.
It must be admitted that to a considerable extent the progress thus
procured has been only technical: it has provided more efficient means
for satisfying preexistent desires, rather than modified the quality of
human purposes.
There is, for example, no modern civilization which is the equal of
Greek culture in all respects. Science is still too recent to have been
absorbed into imaginative and emotional disposition. Men move more
swiftly and surely to the realization of their ends, but their ends too
largely remain what they were prior to scientific enlightenment. This
fact places upon education the responsibility of using science in a way
to modify the habitual attitude of imagination and feeling, not leave it
just an extension of our physical arms and legs.
The advance of science has already modified men's thoughts of the
purposes and goods of life to a sufficient extent to give some idea of
the nature of this responsibility and the ways of meeting it. Science
taking effect in human activity has broken down physical barriers which
formerly separated men; it has immensely widened the area of
intercourse. It has brought about interdependence of interests on an
enormous scale. It has brought with it an established conviction of the
possibility of control of nature in the interests of mankind and thus
has led men to look to the future, instead of the past. The coincidence
of the ideal of progress with the advance of science is not a mere
coincidence. Before this advance men placed the golden age in remote
antiquity. Now they face the future with a firm belief that
intelligence properly used can do away with evils once thought
inevitable. To subjugate devastating disease is no longer a dream; the
hope of abolishing poverty is not utopian. Science has familiarized men
with the idea of development, taking effect practically in persistent
gradual amelioration of the estate of our common humanity.
The problem of an educational use of science is then to create an
intelligence pregnant with belief in the possibility of the direction of
human affairs by itself. The method of science engrained through
education in habit means emancipation from rule of thumb and from the
routine generated by rule of thumb procedure.
The word empirical in its ordinary use does not mean "connected with
experiment," but rather crude and unrational. Under the influence of
conditions created by the non-existence of experimental science,
experience was opposed in all the ruling philosophies of the past to
reason and the truly rational. Empirical knowledge meant the knowledge
accumulated by a multitude of past instances without intelligent insight
into the principles of any of them. To say that medicine was empirical
meant that it was not scientific, but a mode of practice based upon
accumulated observations of diseases and of remedies used more or less
at random. Such a mode of practice is of necessity happy-go-lucky;
success depends upon chance. It lends itself to deception and quackery.
Industry that is "empirically" controlled forbids constructive
applications of intelligence; it depends upon following in an imitative
slavish manner the models set in the past. Experimental science means
the possibility of using past experiences as the servant, not the
master, of mind. It means that reason operates within experience, not
beyond it, to give it an intelligent or reasonable quality. Science is
experience becoming rational. The effect of science is thus to change
men's idea of the nature and inherent possibilities of experience. By
the same token, it changes the idea and the operation of reason.
Instead of being something beyond experience, remote, aloof, concerned
with a sublime region that has nothing to do with the experienced facts
of life, it is found indigenous in experience:—the factor by which
past experiences are purified and rendered into tools for discovery and
advance.
The term "abstract" has a rather bad name in popular speech, being used
to signify not only that which is abstruse and hard to understand, but
also that which is far away from life. But abstraction is an
indispensable trait in reflective direction of activity. Situations do
not literally repeat themselves. Habit treats new occurrences as if
they were identical with old ones; it suffices, accordingly, when the
different or novel element is negligible for present purposes. But when
the new element requires especial attention, random reaction is the sole
recourse unless abstraction is brought into play. For abstraction
deliberately selects from the subject matter of former experiences that
which is thought helpful in dealing with the new. It signifies
conscious transfer of a meaning embedded in past experience for use in a
new one. It is the very artery of intelligence, of the intentional
rendering of one experience available for guidance of another.
Science carries on this working over of prior subject matter on a large
scale. It aims to free an experience from all which is purely personal
and strictly immediate; it aims to detach whatever it has in common with
the subject matter of other experiences, and which, being common, may be
saved for further use. It is, thus, an indispensable factor in social
progress. In any experience just as it occurs there is much which,
while it may be of precious import to the individual implicated in the
experience, is peculiar and unreduplicable.
From the standpoint of science, this material is accidental, while the
features which are widely shared are essential. Whatever is unique in
the situation, since dependent upon the peculiarities of the individual
and the coincidence of circumstance, is not available for others; so
that unless what is shared is abstracted and fixed by a suitable symbol,
practically all the value of the experience may perish in its passing.
But abstraction and the use of terms to record what is abstracted put
the net value of individual experience at the permanent disposal of
mankind. No one can foresee in detail when or how it may be of further
use. The man of science in developing his abstractions is like a
manufacturer of tools who does not know who will use them nor when. But
intellectual tools are indefinitely more flexible in their range of
adaptation than other mechanical tools.
Generalization is the counterpart of abstraction. It is the functioning
of an abstraction in its application to a new concrete
experience,—its extension to clarify and direct new situations.
Reference to these possible applications is necessary in order that the
abstraction may be fruitful, instead of a barren formalism ending in
itself. Generalization is essentially a social device. When men
identified their interests exclusively with the concerns of a narrow
group, their generalizations were correspondingly restricted. The
viewpoint did not permit a wide and free survey. Men's thoughts were
tied down to a contracted space and a short time,—limited to their
own established customs as a measure of all possible values. Scientific
abstraction and generalization are equivalent to taking the point of
view of any man, whatever his location in time and space. While this
emancipation from the conditions and episodes of concrete experiences
accounts for the remoteness, the "abstractness," of science, it also
accounts for its wide and free range of fruitful novel applications in
practice.
Terms and propositions record, fix, and convey what is abstracted. A
meaning detached from a given experience cannot remain hanging in the
air. It must acquire a local habitation. Names give abstract meanings
a physical locus and body. Formulation is thus not an after-thought or
by-product; it is essential to the completion of the work of thought.
Persons know many things which they cannot express, but such knowledge
remains practical, direct, and personal. An individual can use it for
himself; he may be able to act upon it with efficiency. Artists and
executives often have their knowledge in this state. But it is
personal, untransferable, and, as it were, instinctive. To formulate
the significance of an experience a man must take into conscious account
the experiences of others. He must try to find a standpoint which
includes the experience of others as well as his own. Otherwise his
communication cannot be understood. He talks a language which no one
else knows. While literary art furnishes the supreme successes in
stating of experiences so that they are vitally significant to others,
the vocabulary of science is designed, in another fashion, to express
the meaning of experienced things in symbols which any one will know who
studies the science. Æsthetic formulation reveals and enhances the
meaning of experiences one already has; scientific formulation supplies
one with tools for constructing new experiences with transformed
meanings.
To sum up: Science represents the office of intelligence, in projection
and control of new experiences, pursued systematically, intentionally,
and on a scale due to freedom from limitations of habit. It is the sole
instrumentality of conscious, as distinct from accidental, progress.
And if its generality, its remoteness from individual conditions, confer
upon it a certain technicality and aloofness, these qualities are very
different from those of merely speculative theorizing. The latter are
in permanent dislocation from practice; the former are temporarily
detached for the sake of wider and freer application in later concrete
action. There is a kind of idle theory which is antithetical to
practice; but genuinely scientific theory falls within practice as the
agency of its expansion and its direction to new possibilities.
3. Naturalism and Humanism in Education.
—There exists an educational tradition which opposes science to
literature and history in the curriculum. The quarrel between the
representatives of the two interests is easily explicable historically.
Literature and language and a literary philosophy were entrenched in all
higher institutions of learning before experimental science came into
being. The latter had naturally to win its way. No fortified and
protected interest readily surrenders any monopoly it may possess. But
the assumption, from whichever side, that language and literary products
are exclusively humanistic in quality, and that science is purely
physical in import, is a false notion which tends to cripple the
educational use of both studies. Human life does not occur in a vacuum,
nor is nature a mere stage setting for the enactment of its drama
(Ante, p. 247).
Man's life is bound up in the processes of nature; his
career, for success or defeat, depends upon the way in which nature
enters it. Man's power of deliberate control of his own affairs depends
upon ability to direct natural energies to use: an ability which is in
turn dependent upon insight into nature's processes. Whatever natural
science may be for the specialist, for educational purposes it is
knowledge of the conditions of human action. To be aware of the medium
in which social intercourse goes on, and of the means and obstacles to
its progressive development is to be in command of a knowledge which is
thoroughly humanistic in quality. One who is ignorant of the history of
science is ignorant of the struggles by which mankind has passed from
routine and caprice, from superstitious subjection to nature, from
efforts to use it magically, to intellectual self-possession. That
science may be taught as a set of formal and technical exercises is only
too true. This happens whenever information about the world is made an
end in itself. The failure of such instruction to procure culture is
not, however, evidence of the antithesis of natural knowledge to
humanistic concern, but evidence of a wrong educational attitude.
Dislike to employ scientific knowledge as it functions in men's
occupations is itself a survival of an aristocratic culture. The notion
that "applied" knowledge is somehow less worthy than "pure" knowledge,
was natural to a society in which all useful work was performed by
slaves and serfs, and in which industry was controlled by the models set
by custom rather than by intelligence. Science, or the highest knowing,
was then identified with pure theorizing, apart from all application in
the uses of life; and knowledge relating to useful arts suffered the
stigma attaching to the classes who engaged in them (See below, Ch.
XIX). The idea of science thus generated persisted after science had
itself adopted the appliances of the arts, using them for the production
of knowledge, and after the rise of democracy. Taking theory just as
theory, however, that which concerns humanity is of more significance
for man than that which concerns a merely physical world. In adopting
the criterion of knowledge laid down by a literary culture, aloof from
the practical needs of the mass of men, the educational advocates of
scientific education put themselves at a strategic disadvantage. So far
as they adopt the idea of science appropriate to its experimental method
and to the movements of a democratic and industrial society, they have
no difficulty in showing that natural science is more humanistic than an
alleged humanism which bases its educational schemes upon the
specialized interests of a leisure class.
For, as we have already stated, humanistic studies when set in
opposition to study of nature are hampered. They tend to reduce
themselves to exclusively literary and linguistic studies, which in turn
tend to shrink to "the classics," to languages no longer spoken. For
modern languages may evidently be put to use, and hence fall under the
ban. It would be hard to find anything in history more ironical than
the educational practices which have identified the "humanities"
exclusively with a knowledge of Greek and Latin. Greek and Roman art
and institutions made such important contributions to our civilization
that there should always be the amplest opportunities for making their
acquaintance. But to regard them as par excellence the humane studies
involves a deliberate neglect of the possibilities of the subject matter
which is accessible in education to the masses, and tends to cultivate a
narrow snobbery: that of a learned class whose insignia are the
accidents of exclusive opportunity. Knowledge is humanistic in quality
not because it is about human products in the past, but because of
what it does in liberating human intelligence and human sympathy.
Any subject matter which accomplishes this result is humane, and any
subject matter which does not accomplish it is not even educational.
Summary.
—Science represents the fruition of the cognitive factors in
experience. Instead of contenting itself with a mere statement of what
commends itself to personal or customary experience, it aims at a
statement which will reveal the sources, grounds, and consequences of a
belief. The achievement of this aim gives logical character to the
statements. Educationally, it has to be noted that logical
characteristics of method, since they belong to subject matter which has
reached a high degree of intellectual elaboration, are different from
the method of the learner—the chronological order of passing from
a cruder to a more refined intellectual quality of experience. When
this fact is ignored, science is treated as so much bare information,
which however is less interesting and more remote than ordinary
information, being stated in an unusual and technical vocabulary. The
function which science has to perform in the curriculum is that which it
has performed for the race: emancipation from local and temporary
incidents of experience, and the opening of intellectual vistas
unobscured by the accidents of personal habit and predilection. The
logical traits of abstraction, generalization, and definite formulation
are all associated with this function. In emancipating an idea from the
particular context in which it originated and giving it a wider
reference the results of the experience of any individual are put at the
disposal of all men. Thus ultimately and philosophically science is the
organ of general social progress.

Upon the positive side, the value of problems arising
in work in the garden, the shop, etc., may be referred to
(See p. 235).
The laboratory may be treated as an additional resource to supply
conditions and appliances for the better pursuit of these problems.
