       Theories of Knowledge

      1. Continuity versus Dualism. A number of theories of knowing have been criticized in the previous pages. In spite of their differences from one another, they all agree in one fundamental respect which contrasts with the theory which has been positively advanced. The latter assumes continuity; the former state or imply certain basic divisions, separations, or antitheses, technically called dualisms. The origin of these divisions we have found in the hard and fast walls which mark off social groups and classes within a group: like those between rich and poor, men and women, noble and baseborn, ruler and ruled. These barriers mean absence of fluent and free intercourse. This absence is equivalent to the setting up of different types of life-experience, each with isolated subject matter, aim, and standard of values. Every such social condition must be formulated in a dualistic philosophy, if philosophy is to be a sincere account of experience. When it gets beyond dualism—as many philosophies do in form—it can only be by appeal to something higher than anything found in experience, by a flight to some transcendental realm. And in denying duality in name such theories restore it in fact, for they end in a division between things of this world as mere appearances and an inaccessible essence of reality.

      So far as these divisions persist and others are added to them, each leaves its mark upon the educational system, until the scheme of education, taken as a whole, is a deposit of various purposes and procedures. The outcome is that kind of check and balance of segregated factors and values which has been described. (See Chapter XVIII.) The present discussion is simply a formulation, in the terminology of philosophy, of various antithetical conceptions involved in the theory of knowing. In the first place, there is the opposition of empirical and higher rational knowing. The first is connected with everyday affairs, serves the purposes of the ordinary individual who has no specialized intellectual

      pursuit, and brings his wants into some kind of working connection with the immediate environment. Such knowing is depreciated, if not despised, as purely utilitarian, lacking in cultural significance. Rational knowledge is supposed to be something which touches reality in ultimate, intellectual fashion; to be pursued for its own sake and properly to terminate in purely theoretical insight, not debased by application in behavior. Socially, the distinction corresponds to that of the intelligence used by the working classes and that used by a learned class remote from concern with the means of living. Philosophically, the difference turns about the distinction of the particular and universal. Experience is an aggregate of more or less isolated particulars, acquaintance with each of which must be separately made. Reason deals with universals, with general principles, with laws, which lie above the welter of concrete details. In the educational precipitate, the pupil is supposed to have to learn, on one hand, a lot of items of specific information, each standing by itself, and upon the other hand, to become familiar with a certain number of laws and general relationships. Geography, as often taught, illustrates the former; mathematics, beyond the rudiments of figuring, the latter. For all practical purposes, they represent two independent worlds.

      Another antithesis is suggested by the two senses of the word "learning." On the one hand, learning is the sum total of what is known, as that is handed down by books and learned men. It is something external, an accumulation of cognitions as one might store material commodities in a warehouse. Truth exists ready-made somewhere. Study is then the process by which an individual draws on what is in storage. On the other hand, learning means something which the individual does when he studies. It is an active, personally conducted affair. The dualism here is between knowledge as something external, or, as it is often called, objective, and knowing as something purely internal, subjective, psychical. There is, on one side, a body of truth, ready-made, and, on the other, a ready-made mind equipped with a faculty of knowing—if it only wills to exercise it, which it is often strangely loath to do. The separation, often touched upon, between subject matter and method is the educational equivalent of this dualism. Socially the distinction has to do with the part of life which is dependent upon authority and that where individuals are free to advance. Another dualism is that of activity and passivity in knowing. Purely empirical and physical things are often supposed to be known by receiving impressions. Physical things somehow stamp themselves upon the mind or convey themselves into consciousness by means of the sense organs. Rational knowledge and knowledge of spiritual things is supposed, on the contrary, to spring from activity initiated within the mind, an activity carried on better if it is kept remote from all sullying touch of the senses and external objects. The distinction between sense training and object lessons and laboratory exercises, and pure ideas contained in books, and appropriated—so it is thought—by some miraculous output of mental energy, is a fair expression in education of this distinction. Socially, it reflects a division between those who are controlled by direct concern with things and those who are free to cultivate themselves.

      Another current opposition is that said to exist between the intellect and the emotions. The emotions are conceived to be purely private and personal, having nothing to do with the work of pure intelligence in apprehending facts and truths,—except perhaps the single emotion of intellectual curiosity. The intellect is a pure light; the emotions are a disturbing heat. The mind turns outward to truth; the emotions turn inward to considerations of personal advantage and loss. Thus in education we have that systematic depreciation of interest which has been noted, plus the necessity in practice, with most pupils, of recourse to extraneous and irrelevant rewards and penalties in order to induce the person who has a mind (much as his clothes have a pocket) to apply that mind to the truths to be known. Thus we have the spectacle of professional educators decrying appeal to interest while they uphold with great dignity the need of reliance upon examinations, marks, promotions and emotions, prizes, and the time-honored paraphernalia of rewards and punishments. The effect of this situation in crippling the teacher's sense of humor has not received the attention which it deserves.

      All of these separations culminate in one between knowing and doing, theory and practice, between mind as the end and spirit of action and the body as its organ and means. We shall not repeat what has been said about the source of this dualism in the division of society into a class laboring with their muscles for material sustenance and a class which, relieved from economic pressure, devotes itself to the arts of expression and social direction. Nor is it necessary to speak again of the educational evils which spring from the separation. We shall be content to summarize the forces which tend to make the untenability of this conception obvious and to replace it by the idea of continuity. (i) The advance of physiology and the psychology associated with it have shown the connection of mental activity with that of the nervous system. Too often recognition of connection has stopped short at this point; the older dualism of soul and body has been replaced by that of the brain and the rest of the body. But in fact the nervous system is only a specialized mechanism for keeping all bodily activities working together. Instead of being isolated from them, as an organ of knowing from organs of motor response, it is the organ by which they interact responsively with one another. The brain is essentially an organ for effecting the reciprocal adjustment to each other of the stimuli received from the environment and responses directed upon it. Note that the adjusting is reciprocal; the brain not only enables organic activity to be brought to bear upon any object of the environment in response to a sensory stimulation, but this response also determines what the next stimulus will be. See what happens, for example, when a carpenter is at work upon a board, or an etcher upon his plate—or in any case of a consecutive activity. While each motor response is adjusted to the state of affairs indicated through the sense organs, that motor response shapes the next sensory stimulus. Generalizing this illustration, the brain is the machinery for a constant reorganizing of activity so as to maintain its continuity; that is to say, to make such modifications in future action as are required because of what has already been done. The continuity of the work of the carpenter distinguishes it from a routine repetition of identically
