Summary. In the previous chapter we found that the primary subject

matter of knowing is that contained in learning how to do things of a fairly direct sort. The educational equivalent of this principle is the consistent use of simple occupations which appeal to the powers of youth and which typify general modes of social activity. Skill and information about materials, tools, and laws of energy are acquired while activities are carried on for their own sake. The fact that they are socially representative gives a quality to the skill and knowledge gained which makes them transferable to out-of-school situations. It is important not to confuse the psychological distinction between play and work with the economic distinction. Psychologically, the defining characteristic of play is not amusement nor aimlessness. It is the fact that the aim is thought of as more activity in the same line, without defining continuity of action in reference to results produced. Activities as they grow more complicated gain added meaning by greater attention to specific results achieved. Thus they pass gradually into work. Both are equally free and intrinsically motivated, apart from false economic conditions which tend to make play into idle excitement for the well to do, and work into uncongenial labor for the poor. Work is psychologically simply an activity which consciously includes regard for consequences as a part of itself; it becomes constrained labor when the consequences are outside of the activity as an end to which activity is merely a means. Work which remains permeated with the play attitude is art—in quality if not in conventional designation.

Chapter Sixteen: The Significance of Geography and History

1. Extension of Meaning of Primary Activities. Nothing is more striking than the difference between an activity as merely physical and the wealth of meanings which the same activity may assume. From the outside, an astronomer gazing through a telescope is like a small boy looking through the same tube. In each case, there is an arrangement of glass and metal, an eye, and a little speck of light in the distance. Yet at a critical moment, the activity of an astronomer might be concerned with the birth of a world, and have whatever is known about the starry heavens as its significant content. Physically speaking, what man has effected on this globe in his progress from savagery is a mere scratch on its surface, not perceptible at a distance which is slight in comparison with the reaches even of the solar system. Yet in meaning what has been accomplished measures just the difference of civilization from savagery. Although the activities, physically viewed, have changed somewhat, this change is slight in comparison with the development of the meanings attaching to the activities. There is no limit to the meaning which an action may come to possess. It all depends upon the context of perceived connections in which it is placed; the reach of imagination in realizing connections is inexhaustible. The advantage which the activity of man has in appropriating and finding meanings makes his education something else than the manufacture of a tool or the training of an animal. The latter increase efficiency; they do not develop significance. The final educational importance of such occupations in play and work as were considered in the last chapter is that they afford the most direct instrumentalities for such extension of meaning. Set going under adequate conditions they are magnets for gathering and retaining an indefinitely wide scope of intellectual considerations. They provide vital centers for the reception and assimilation of information. When information is purveyed in chunks simply as information to be retained for its own sake, it tends to stratify over vital experience. Entering as a factor into an activity pursued for its own sake—whether as a means or as a widening of the content of the aim—it is informing. The insight directly gained fuses with what is told. Individual experience is then capable of taking up and holding in solution the net results of the experience of the group to which he belongs—including the results of sufferings and trials over long stretches of time. And such media have no fixed saturation point where further absorption is impossible. The more that is taken in, the greater capacity there is for further assimilation. New receptiveness follows upon new curiosity, and new curiosity upon information gained.

The meanings with which activities become charged, concern nature and man. This is an obvious truism, which however gains meaning when translated into educational equivalents. So translated, it signifies that geography and history supply subject matter which gives background and outlook, intellectual perspective, to what might otherwise be narrow personal actions or mere forms of technical skill. With every increase of ability to place our own doings in their time and space connections, our doings gain in significant content. We realize that we are citizens of no mean city in discovering the scene in space of which we are denizens, and the continuous manifestation of endeavor in time of which we are heirs and continuers. Thus our ordinary daily experiences cease to be things of the moment and gain enduring substance. Of course if geography and history are taught as ready-made studies which a person studies simply because he is sent to school, it easily happens that a large number of statements about things remote and alien to everyday experience are learned. Activity is divided, and two separate worlds are built up, occupying activity at divided periods. No transmutation takes place; ordinary experience is not enlarged in meaning by getting its connections; what is studied is not animated and made real by entering into immediate activity. Ordinary experience is not even left as it was, narrow but vital. Rather, it loses something of its mobility and sensitiveness to suggestions. It is weighed down and pushed into a corner by a load of unassimilated information. It parts with its flexible responsiveness and alert eagerness for additional meaning. Mere amassing of information apart from the direct interests of life makes mind wooden; elasticity disappears.

Normally every activity engaged in for its own sake reaches out beyond its immediate self. It does not passively wait for information to be bestowed which will increase its meaning; it seeks it out. Curiosity is not an accidental isolated possession; it is a necessary consequence of the fact that an experience is a moving, changing thing, involving all kinds of connections with other things. Curiosity is but the tendency to make these conditions perceptible. It is the business of educators to supply an environment so that this reaching out of an experience may be fruitfully rewarded and kept continuously active. Within a certain kind of environment, an activity may be checked so that the only meaning which accrues is of its direct and tangible isolated outcome. One may cook, or hammer, or walk, and the resulting consequences may not take the mind any farther than the consequences of cooking, hammering, and walking in the literal—or physical—sense. But nevertheless the consequences of the act remain far-reaching. To walk involves a displacement and reaction of the resisting earth, whose thrill is felt wherever there is matter. It involves the structure of the limbs and the nervous system; the principles of mechanics. To cook is to utilize heat and moisture to change the chemical relations of food materials; it has a bearing upon the assimilation of food and the growth of the body. The utmost that the most learned men of science know in physics, chemistry, physiology is not enough to make all these consequences and connections perceptible. The task of education, once more, is to see to it that such activities are performed in such ways and under such conditions as render these conditions as perceptible as possible. To "learn geography" is to gain in power to perceive the spatial, the natural, connections of an ordinary act; to "learn history" is essentially to gain in power to recognize its human connections. For what is called geography as a formulated study is simply the body of facts and principles which have been discovered in other men's experience about the natural medium in which we live, and in connection with which the particular acts of our life have an explanation. So history as a formulated study is but the body of known facts about the activities and sufferings of the social groups with which our own lives are continuous, and through reference to which our own customs and institutions are illuminated.

2. The Complementary Nature of History and Geography. History and geography—including in the latter, for reasons about to be mentioned, nature study—are the information studies par excellence of the schools. Examination of the materials and the method of their use will make clear that the difference between penetration of this information into living experience and its mere piling up in isolated heaps depends upon whether these studies are faithful to the interdependence of man and nature which affords these studies their justification. Nowhere, however, is there greater danger that subject matter will be accepted as appropriate educational material simply because it has become customary to teach and learn it. The idea of a philosophic reason for it, because of the function of the material in a worthy transformation of experience, is looked upon as a vain fancy, or as supplying a high-sounding phraseology in support of what is already done. The words "history" and "geography" suggest simply the matter which has been traditionally sanctioned in the schools. The mass and variety of this matter discourage an attempt to see what it really stands for, and how it can be so taught as to fulfill its mission in the experience of pupils. But unless the idea that there is a unifying and social direction in education is a farcical pretense, subjects that bulk as large in the curriculum as history and geography, must represent a general function in the development of a truly socialized and intellectualized experience. The discovery of this function must be employed as a criterion for trying and sifting the facts taught and the methods used.

The function of historical and geographical subject matter has been stated; it is to enrich and liberate the more direct and personal contacts of life by furnishing their context, their background and outlook. While geography emphasizes the physical side and history the social, these are only emphases in a common topic, namely, the associated life of men. For this associated life, with its experiments, its ways and means, its achievements and failures, does not go on in the sky nor yet in a vacuum. It takes place on the earth. This setting of nature does not bear to social activities the relation that the scenery of a theatrical performance bears to a dramatic representation; it enters into the very make-up of the social happenings that form history. Nature is the medium of social occurrences. It furnishes original stimuli; it supplies obstacles and resources. Civilization is the progressive mastery of its varied energies. When this interdependence of the study of history, representing the human emphasis, with the study of geography, representing the natural, is ignored, history sinks to a listing of dates with an appended inventory of events, labeled "important"; or else it becomes a literary phantasy—for in purely literary history the natural environment is but stage scenery.

Geography, of course, has its educative influence in a counterpart connection of natural facts with social events and their consequences. The classic definition of geography as an account of the earth as the home of man expresses the educational reality. But it is easier to give this definition than it is to present specific geographical subject matter in its vital human bearings. The residence, pursuits, successes, and failures of men are the things that give the geographic data their reason for inclusion in the material of instruction. But to hold the two together requires an informed and cultivated imagination. When the ties are broken, geography presents itself as that hodge-podge of unrelated fragments too often found. It appears as a veritable rag-bag of intellectual odds and ends: the height of a mountain here, the course of a river there, the quantity of shingles produced in this town, the tonnage of the shipping in that, the boundary of a county, the capital of a state. The earth as the home of man is humanizing and unified; the earth viewed as a miscellany of facts is scattering and imaginatively inert. Geography is a topic that originally appeals to imagination—even to the romantic imagination. It shares in the wonder and glory that attach to adventure, travel, and exploration. The variety of peoples and environments, their contrast with familiar scenes, furnishes infinite stimulation. The mind is moved from the monotony of the customary. And while local or home geography is the natural starting point in the reconstructive development of the natural environment, it is an intellectual starting point for moving out into the unknown, not an end in itself. When not treated as a basis for getting at the large world beyond, the study of the home geography becomes as deadly as do object lessons which simply summarize the properties of familiar objects. The reason is the same. The imagination is not fed, but is held down to recapitulating, cataloguing, and refining what is already known. But when the familiar fences that mark the limits of the village proprietors are signs that introduce an understanding of the boundaries of great nations, even fences are lighted with meaning. Sunlight, air, running water, inequality of earth's surface, varied industries, civil officers and their duties—all these things are found in the local environment. Treated as if their meaning began and ended in those confines, they are curious facts to be laboriously learned. As instruments for extending the limits of experience, bringing within its scope peoples and things otherwise strange and unknown, they are transfigured by the use to which they are put. Sunlight, wind, stream, commerce, political relations come from afar and lead the thoughts afar. To follow their course is to enlarge the mind not by stuffing it with additional information, but by remaking the meaning of what was previously a matter of course.

The same principle coordinates branches, or phases, of geographical study which tend to become specialized and separate. Mathematical or astronomical, physiographic, topographic, political, commercial, geography, all make their claims. How are they to be adjusted? By an external compromise that crowds in so much of each? No other method is to be found unless it be constantly borne in mind that the educational center of gravity is in the cultural or humane aspects of the subject. From this center, any material becomes relevant in so far as it is needed to help appreciate the significance of human activities and relations. The differences of civilization in cold and tropical regions, the special inventions, industrial and political, of peoples in the temperate regions, cannot be understood without appeal to the earth as a member of the solar system. Economic activities deeply influence social intercourse and political organization on one side, and reflect physical conditions on the other. The specializations of these topics are for the specialists; their interaction concerns man as a being whose experience is social.

To include nature study within geography doubtless seems forced; verbally, it is. But in educational idea there is but one reality, and it is pity that in practice we have two names: for the diversity of names tends to conceal the identity of meaning. Nature and the earth should be equivalent terms, and so should earth study and nature study. Everybody knows that nature study has suffered in schools from scrappiness of subject matter, due to dealing with a large number of isolated points. The parts of a flower have been studied, for example, apart from the flower as an organ; the flower apart from the plant; the plant apart from the soil, air, and light in which and through which it lives. The result is an inevitable deadness of topics to which attention is invited, but which are so isolated that they do not feed imagination. The lack of interest is so great that it was seriously proposed to revive animism, to clothe natural facts and events with myths in order that they might attract and hold the mind. In numberless cases, more or less silly personifications were resorted to. The method was silly, but it expressed a real need for a human atmosphere. The facts had been torn to pieces by being taken out of their context. They no longer belonged to the earth; they had no abiding place anywhere. To compensate, recourse was had to artificial and sentimental associations. The real remedy is to make nature study a study of nature, not of fragments made meaningless through complete removal from the situations in which they are produced and in which they operate. When nature is treated as a whole, like the earth in its relations, its phenomena fall into their natural relations of sympathy and association with human life, and artificial substitutes are not needed.

3. History and Present Social Life. The segregation which kills the vitality of history is divorce from present modes and concerns of social life. The past just as past is no longer our affair. If it were wholly gone and done with, there would be only one reasonable attitude toward it. Let the dead bury their dead. But knowledge of the past is the key to understanding the present. History deals with the past, but this past is the history of the present. An intelligent study of the discovery, explorations, colonization of America, of the pioneer movement westward, of immigration, etc., should be a study of the United States as it is to-day: of the country we now live in. Studying it in process of formation makes much that is too complex to be directly grasped open to comprehension. Genetic method was perhaps the chief scientific achievement of the latter half of the nineteenth century. Its principle is that the way to get insight into any complex product is to trace the process of its making,—to follow it through the successive stages of its growth. To apply this method to history as if it meant only the truism that the present social state cannot be separated from its past, is one-sided. It means equally that past events cannot be separated from the living present and retain meaning. The true starting point of history is always some present situation with its problems.

This general principle may be briefly applied to a consideration of its bearing upon a number of points. The biographical method is generally recommended as the natural mode of approach to historical study. The lives of great men, of heroes and leaders, make concrete and vital historic episodes otherwise abstract and incomprehensible. They condense into vivid pictures complicated and tangled series of events spread over so much space and time that only a highly trained mind can follow and unravel them. There can be no doubt of the psychological soundness of this principle. But it is misused when employed to throw into exaggerated relief the doings of a few individuals without reference to the social situations which they represent. When a biography is related just as an account of the doings of a man isolated from the conditions that aroused him and to which his activities were a response, we do not have a study of history, for we have no study of social life, which is an affair of individuals in association. We get only a sugar coating which makes it easier to swallow certain fragments of information. Much attention has been given of late to primitive life as an introduction to learning history. Here also there is a right and a wrong way of conceiving its value. The seemingly ready-made character and the complexity of present conditions, their apparently hard and fast character, is an almost insuperable obstacle to gaining insight into their nature. Recourse to the primitive may furnish the fundamental elements of the present situation in immensely simplified form. It is like unraveling a cloth so complex and so close to the eyes that its scheme cannot be seen, until the larger coarser features of the pattern appear. We cannot simplify the present situations by deliberate experiment, but resort to primitive life presents us with the sort of results we should desire from an experiment. Social relationships and modes of organized action are reduced to their lowest terms. When this social aim is overlooked, however, the study of primitive life becomes simply a rehearsing of sensational and exciting features of savagery. Primitive history suggests industrial history. For one of the chief reasons for going to more primitive conditions to resolve the present into more easily perceived factors is that we may realize how the fundamental problems of procuring subsistence, shelter, and protection have been met; and by seeing how these were solved in the earlier days of the human race, form some conception of the long road which has had to be traveled, and of the successive inventions by which the race has been brought forward in culture. We do not need to go into disputes regarding the economic interpretation of history to realize that the industrial history of mankind gives insight into two important phases of social life in a way which no other phase of history can possibly do. It presents us with knowledge of the successive inventions by which theoretical science has been applied to the control of nature in the interests of security and prosperity of social life. It thus reveals the successive causes of social progress. Its other service is to put before us the things that fundamentally concern all men in common—the occupations and values connected with getting a living. Economic history deals with the activities, the career, and fortunes of the common man as does no other branch of history. The one thing every individual must do is to live; the one thing that society must do is to secure from each individual his fair contribution to the general well being and see to it that a just return is made to him.

Economic history is more human, more democratic, and hence more liberalizing than political history. It deals not with the rise and fall of principalities and powers, but with the growth of the effective liberties, through command of nature, of the common man for whom powers and principalities exist.

Industrial history also offers a more direct avenue of approach to the realization of the intimate connection of man's struggles, successes, and failures with nature than does political history—to say nothing of the military history into which political history so easily runs when reduced to the level of youthful comprehension. For industrial history is essentially an account of the way in which man has learned to utilize natural energy from the time when men mostly exploited the muscular energies of other men to the time when, in promise if not in actuality, the resources of nature are so under command as to enable men to extend a common dominion over her. When the history of work, when the conditions of using the soil, forest, mine, of domesticating and cultivating grains and animals, of manufacture and distribution, are left out of account, history tends to become merely literary—a systematized romance of a mythical humanity living upon itself instead of upon the earth.

Perhaps the most neglected branch of history in general education is intellectual history. We are only just beginning to realize that the great heroes who have advanced human destiny are not its politicians, generals, and diplomatists, but the scientific discoverers and inventors who have put into man's hands the instrumentalities of an expanding and controlled experience, and the artists and poets who have celebrated his struggles, triumphs, and defeats in such language, pictorial, plastic, or written, that their meaning is rendered universally accessible to others. One of the advantages of industrial history as a history of man's progressive adaptation of natural forces to social uses is the opportunity which it affords for consideration of advance in the methods and results of knowledge. At present men are accustomed to eulogize intelligence and reason in general terms; their fundamental importance is urged. But pupils often come away from the conventional study of history, and think either that the human intellect is a static quantity which has not progressed by the invention of better methods, or else that intelligence, save as a display of personal shrewdness, is a negligible historic factor. Surely no better way could be devised of instilling a genuine sense of the part which mind has to play in life than a study of history which makes plain how the entire advance of humanity from savagery to civilization has been dependent upon intellectual discoveries and inventions, and the extent to which the things which ordinarily figure most largely in historical writings have been side issues, or even obstructions for intelligence to overcome.

Pursued in this fashion, history would most naturally become of ethical value in teaching. Intelligent insight into present forms of associated life is necessary for a character whose morality is more than colorless innocence. Historical knowledge helps provide such insight. It is an organ for analysis of the warp and woof of the present social fabric, of making known the forces which have woven the pattern. The use of history for cultivating a socialized intelligence constitutes its moral significance. It is possible to employ it as a kind of reservoir of anecdotes to be drawn on to inculcate special moral lessons on this virtue or that vice. But such teaching is not so much an ethical use of history as it is an effort to create moral impressions by means of more or less authentic material. At best, it produces a temporary emotional glow; at worst, callous indifference to moralizing. The assistance which may be given by history to a more intelligent sympathetic understanding of the social situations of the present in which individuals share is a permanent and constructive moral asset.

Summary. It is the nature of an experience to have implications which

go far beyond what is at first consciously noted in it. Bringing these connections or implications to consciousness enhances the meaning of the experience. Any experience, however trivial in its first appearance, is capable of assuming an indefinite richness of significance by extending its range of perceived connections. Normal communication with others is the readiest way of effecting this development, for it links up the net results of the experience of the group and even the race with the immediate experience of an individual. By normal communication is meant that in which there is a joint interest, a common interest, so that one is eager to give and the other to take. It contrasts with telling or stating things simply for the sake of impressing them upon another, merely in order to test him to see how much he has retained and can literally reproduce.

Geography and history are the two great school resources for bringing about the enlargement of the significance of a direct personal experience. The active occupations described in the previous chapter reach out in space and time with respect to both nature and man. Unless they are taught for external reasons or as mere modes of skill their chief educational value is that they provide the most direct and interesting roads out into the larger world of meanings stated in history and geography. While history makes human implications explicit and geography natural connections, these subjects are two phases of the same living whole, since the life of men in association goes on in nature, not as an accidental setting, but as the material and medium of development.

Chapter Seventeen: 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. 190). As from a few bones the competent zoologist 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. 1 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 formulae, 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, formulae, 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. Aesthetic 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. 211). 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.
