contribute to a single outcome. But if each views the consequences of his own acts as having a bearing upon what others are doing and takes into account the consequences of their behavior upon himself, then there is a common mind; a common intent in behavior. There is an understanding set up between the different contributors; and this common understanding controls the action of each. Suppose that conditions were so arranged that one person automatically caught a ball and then threw it to another person who caught and automatically returned it; and that each so acted without knowing where the ball came from or went to. Clearly, such action would be without point or meaning. It might be physically controlled, but it would not be socially directed. But suppose that each becomes aware of what the other is doing, and becomes interested in the other's action and thereby interested in what he 14 is doing himself as connected with the action of the other. The behavior of each would then be intelligent; and socially intelligent and guided. Take one more example of a less imaginary kind. An infant is hungry, and cries while food is prepared in his presence. If he does not connect his own state with what others are doing, nor what they are doing with his own satisfaction, he simply reacts with increasing impatience to his own increasing discomfort. He is physically controlled by his own organic state. But when he makes a back and forth reference, his whole attitude changes. He takes an interest, as we say; he takes note and watches what others are doing. He no longer reacts just to his own hunger, but behaves in the light of what others are doing for its prospective satisfaction. In that way, he also no longer just gives way to hunger without knowing it, but he notes, or recognizes, or identifies his own state. It becomes an object for him. His attitude toward it becomes in some degree intelligent. And in such noting of the meaning of the actions of others and of his own state, he is socially directed. It will be recalled that our main proposition had two sides. One of them has now been dealt with: namely, that physical things do not influence mind (or form ideas and beliefs) except as they are implicated in action for prospective consequences. The other point is persons modify one another's dispositions only through the special use they make of physical conditions. Consider first the case of so-called expressive movements to which others are sensitive; blushing, smiling, frowning, clinching of fists, natural gestures of all kinds. In themselves, these are not expressive. They are organic parts of a person's attitude. One does not blush to show modesty or embarrassment to others, but because the capillary circulation alters in response to stimuli. But others use the blush, or a slightly perceptible tightening of the muscles of a person with whom they are associated, as a sign of the state in which that person finds himself, and as an indication of what course to pursue. The frown signifies an imminent rebuke for which one must prepare, or an uncertainty and hesitation which one must, if possible, remove by saying or doing something to restore confidence. A man at some distance is waving his arms wildly. One has only to preserve an attitude of detached indifference, and the motions of the other person will be on the level of any remote physical change which we happen to note. If we have no concern or interest, the waving of the arms is as meaningless to us as the gyrations of the arms of a windmill. But if interest is aroused, we begin to participate. We refer his action to something we are doing ourselves or that we should do. We have to judge the meaning of his act in order to decide what to do. Is he beckoning for help? Is he warning us of an explosion to be set off, against which we should guard ourselves? In one case, his action means to run toward him; in the other case, to run away. In any case, it is the change he effects in the physical environment which is a sign to us of how we should conduct ourselves. Our action is socially controlled because we endeavor to refer what we are to do to the same situation in which he is acting. Language is, as we have already seen (ante, p. 15) a case of this joint reference of our own action and that of another to a common situation. Hence its unrivaled significance as a means of social direction. But language would not be this efficacious instrument were it not that it takes place upon a background of coarser and more tangible use of physical means to accomplish results. A child sees persons with whom he lives using chairs, hats, tables, spades, saws, plows, horses, money in certain ways. If he has any share at all in what they are doing, he is led thereby to use things in the same way, or to use other things in a way which will fit in. If a chair is drawn up to a table, it is a sign that he is to sit in it; if a person extends his right hand, he is to extend his; and so on in a never ending stream of detail. The prevailing habits of using the products of human art and the raw materials of nature constitute by all odds the deepest and most pervasive mode of social control. When children go to school, they already have "minds"--they have knowledge and dispositions of judgment which may be appealed to through the use of language. But these "minds" are the organized habits of intelligent response which they have previously required by putting things to use in connection with the way other persons use things. The control is inescapable; it saturates disposition. The net outcome of the discussion is that the fundamental means of control is not personal but intellectual. It is not "moral" in the sense that a person is moved by direct personal appeal from others, important as is this method at critical junctures. It consists in the habits of understanding, which are set up in using objects in correspondence with others, whether by way of cooperation and assistance or rivalry and competition. Mind as a concrete thing is precisely the power to understand things in terms of the use made of them; a socialized mind is the power to understand them in terms of the use to which they are turned in joint or shared situations. And mind in this sense is the method of social control. 3. Imitation and Social Psychology. We have already noted the defects of a psychology of learning which places the individual mind naked, as it were, in contact with physical objects, and which believes that knowledge, ideas, and beliefs accrue from their interaction. Only comparatively recently has the predominating influence of association with fellow beings in the formation of mental and moral disposition been perceived. Even now it is usually treated as a kind of adjunct to an alleged method of learning by direct contact with things, and as merely supplementing knowledge of the physical world with knowledge of persons. The purport of our discussion is that such a view makes an absurd and impossible separation between persons and things. Interaction with things may form habits of external adjustment. But it leads to activity having a meaning and conscious intent only when things are used to produce a result. And the only way one person can modify the mind of another is by using physical conditions, crude or artificial, so as to evoke some answering activity from him. Such are our two main conclusions. It is desirable to amplify and enforce them by placing them in contrast with the theory which uses a psychology of supposed direct relationships of human beings to one another as an adjunct to the psychology of the supposed direct relation of an individual to physical objects. In substance, this so-called social psychology has been built upon the notion of imitation. Consequently, we shall discuss the nature and role of imitation in the formation of mental disposition. 15 According to this theory, social control of individuals rests upon the instinctive tendency of individuals to imitate or copy the actions of others. The latter serve as models. The imitative instinct is so strong that the young devote themselves to conforming to the patterns set by others and reproducing them in their own scheme of behavior. According to our theory, what is here called imitation is a misleading name for partaking with others in a use of things which leads to consequences of common interest. The basic error in the current notion of imitation is that it puts the cart before the horse. It takes an effect for the cause of the effect. There can be no doubt that individuals in forming a social group are likeminded; they understand one another. They tend to act with the same controlling ideas, beliefs, and intentions, given similar circumstances. Looked at from without, they might be said to be engaged in "imitating" one another. In the sense that they are doing much the same sort of thing in much the same sort of way, this would be true enough. But "imitation" throws no light upon why they so act; it repeats the fact as an explanation of itself. It is an explanation of the same order as the famous saying that opium puts men to sleep because of its dormitive power. Objective likeness of acts and the mental satisfaction found in being in conformity with others are baptized by the name imitation. This social fact is then taken for a psychological force, which produced the likeness. A considerable portion of what is called imitation is simply the fact that persons being alike in structure respond in the same way to like stimuli. Quite independently of imitation, men on being insulted get angry and attack the insulter. This statement may be met by citing the undoubted fact that response to an insult takes place in different ways in groups having different customs. In one group, it may be met by recourse to fisticuffs, in another by a challenge to a duel, in a third by an exhibition of contemptuous disregard. This happens,
