22. Hunger, love, vanity, and fear. There are four great motives of human action which come into play when some number of human beings are in juxtaposition under the same life conditions. These are hunger, sex passion, vanity, and fear (of ghosts and spirits). Under each of these motives there are interests. Life consists in satisfying interests, for "life," in a society, is a career of action and effort expended on both the material and social environment. However great the errors and misconceptions may be which are included in the efforts, the purpose always is advantage and expediency. The efforts fall into parallel lines, because the conditions and the interests are the same. It is now the accepted opinion, and it may be correct, that men inherited from their beast ancestors psychophysical traits, instincts, and dexterities, or at least predispositions, which give them aid in solving the problems of food supply, sex, commerce, and vanity. The result is mass phenomena; currents of similarity, concurrence, and mutual contribution; and these produce folkways. The folkways are unconscious, spontaneous, uncoördinated. It is never known who led in devising them, although we must believe that talent exerted its leadership at all times. Folkways come into existence now all the time. There were folkways in stage coach times, which were fitted to that mode of travel. Street cars have produced ways which are suited to that mode of transportation in cities. The telephone has produced ways which have not been invented and imposed by anybody, but which are devised to satisfy conveniently the interests which are at stake in the use of that instrument.
23. Process of making folkways. Although we may see the process of making folkways going on all the time, the analysis of the process is very difficult. It appears as if there was a "mind" in the crowd which was different from the minds of the individuals which compose it. Indeed some have adopted such a doctrine. By autosuggestion the stronger minds produce ideas which when set afloat pass by suggestion from mind to mind. Acts which are consonant with the ideas are imitated. There is a give and take between man and man. This process is one of development. New suggestions come in at point after point. They are carried out. They combine with what existed already. Every new step increases the number of points upon which other minds may seize. It seems to be by this process that great inventions are produced. Knowledge has been won and extended by it. It seems as if the crowd had a mystic power in it greater than the sum of the powers of its members. It is sufficient, however, to explain this, to notice that there is a coöperation and constant suggestion which is highly productive when it operates in a crowd, because it draws out latent power, concentrates what would otherwise be scattered, verifies and corrects what has been taken up, eliminates error, and constructs by combination. Hence the gain from the collective operation is fully accounted for, and the theories of Völkerpsychologie are to be rejected as superfluous. Out of the process which has been described have come the folkways during the whole history of civilization.
The phenomena of suggestion and suggestibility demand some attention because the members of a group are continually affecting each other by them, and great mass phenomena very often are to be explained by them.
24. Suggestion; suggestibility. What has been called the psychology of crowds consists of certain phenomena of suggestion. A number of persons assembled together, especially if they are enthused by the same sentiment or stimulated by the same interest, transmit impulses to each other with the result that all the impulses are increased in a very high ratio. In other words, it is an undisputed fact that all mental states and emotions are greatly increased in force by transmission from man to man, especially if they are attended by a sense of the concurrence and coöperation of a great number who have a common sentiment or interest. "The element of psychic coercion to which our thought process is subject is the characteristic of the operations which we call suggestive."33 What we have done or heard occupies our minds so that we cannot turn from it to something else. The consensus of a number promises triumph for the impulse, whatever it is. Ça ira. There is a thrill of enthusiasm in the sense of moving with a great number. There is no deliberation or reason. Therefore a crowd may do things which are either better or worse than what individuals in it would do. Cases of lynching show how a crowd can do things which it is extremely improbable that the individuals would do or consent to, if they were taken separately. The crowd has no greater guarantee of wisdom and virtue than an individual would have. In fact, the participants in a crowd almost always throw away all the powers of wise judgment which have been acquired by education, and submit to the control of enthusiasm, passion, animal impulse, or brute appetite. A crowd always has a common stock of elementary faiths, prejudices, loves and hates, and pet notions. The common stock is acted on by the same stimuli, in all the persons, at the same time. The response, as an aggregate, is a great storm of feeling, and a great impulse to the will. Hence the great influence of omens and of all popular superstitions on a crowd. Omens are a case of "egoistic reference."34 An army desists from a battle on account of an eclipse. A man starting out on the food quest returns home because a lizard crosses his path. In each case an incident in nature is interpreted as a warning or direction to the army or the man. Thus momentous results for men and nations may be produced without cause. The power of watchwords consists in the cluster of suggestions which has become fastened upon them. In the Middle Ages the word "heretic" won a frightful suggestion of base wickedness. In the seventeenth century the same suggestions were connected with the words "witch" and "traitor." "Nature" acquired great suggestion of purity and correctness in the eighteenth century, which it has not yet lost. "Progress" now bears amongst us a very undue weight of suggestion. Suggestibility is the quality of liability to suggestive influence.35 "Suggestibility is the natural faculty of the brain to admit any ideas whatsoever, without motive, to assimilate them, and eventually to transform them rapidly into movements, sensations, and inhibitions."36 It differs greatly in degree, and is present in different grades in different crowds. Crowds of different nationalities would differ both in degree of suggestibility and in the kinds of suggestive stimuli to which they would respond. Imitation is due to suggestibility. Even suicide is rendered epidemic by suggestion and imitation.37 In a crisis, like a shipwreck, when no one knows what to do, one, by acting, may lead them all through imitative suggestibility. People who are very suggestible can be led into states of mind which preclude criticism or reflection. Any one who acquires skill in the primary processes of association, analogy, reiteration, and continuity, can play tricks on others by stimulating these processes and then giving them selected data to work upon. A directive idea may be suggested by a series of ideas which lead the recipient of them to expect that the series will be continued. Then he will not perceive if the series
