Moreover, such contagious examples in the public do not usually lead to such unexpected movements as they easily induce in the crowd. But here, too, the infection frequently acts in defiance of a man's sound intelligence; complete points of view are accepted upon trust and faith, without further discussion, and frequently immature resolutions are formed. On the boards representing the stage of the world there are ever moving idols, who after the first storm of admiration which they call out, sink back into oblivion. The fame of the people's leaders maintains itself in quite the same way by means of psychical infection through the similar national interest of a unified group. It has often happened that their brightness was extinguished with the first opposition which the masses saw setting its face against their wishes and ideals. What we, however, see in close popular masses recurs to a certain degree in every social milieu, in every larger society.
Between the single elements of such social spheres there occur uninterrupted psychical infections and contra-infections. Ever according to the nature of the material of the infection that has been received, the individual feels himself attracted to the sublime and the noble, or to the lower and bestial. Is, then, the intercourse between teacher and pupil, between friends, between lovers, uninfluenced by reciprocal suggestion? Suicide pacts and other mutual acts present a certain participation of interacting suggestion. Yet more. Hardly a single deed whatever occurs that stands out over the everyday, hardly a crime is committed, without the concurrence of third persons, direct or indirect, not unseldom bearing a likeness to the effects of suggestion.
We must here admit that Tarde was right when he said that it is less difficult to find crimes of the crowd than to discover crimes which were not such and which would indicate no sort of promotion or participation of the environment. That is true to such a degree that one may ask whether there are any individual crimes at all, as the question is also conceivable whether there are any works of genius which do not have a collective character.
Many believe that crimes are always pondered. A closer insight into the behavior of criminals testifies, however, in many cases that even when there is a long period of indecision, a single encouraging word from the environment, an example with a suggestive effect, is quite sufficient to scatter all considerations and to bring the criminal intention to the deed. In organized societies, too, a mere nod from the chief may often lead with magic power to a crime.
The ideas, efforts, and behavior of the individual may by no means be looked on as something sharply distinct, individually peculiar, since from the form and manner of these ideas, efforts, and behavior, there shines forth ever, more or less, the influence of the milieu.
In close connection with this fact there stands also the so-called astringent effect of the milieu upon the individuals who are incapable of rising out of their environment, of stepping out of it. In society that bacillus for which one has found the name "suggestion" appears certainly as a leveling element, and, accordingly, whether the individual stands higher or lower than his environment, whether he becomes worse or better under its influence, he always loses or gains something from the contact with others. This is the basis of the great importance of suggestion as a factor in imposing a social uniformity upon individuals.
The power of suggestion and contra-suggestion, however, extends yet further. It enhances sentiments and aims and enkindles the activity of the masses to an unusual degree.
Many historical personages who knew how to embody in themselves the emotions and the desires of the masses—we may think of Jeanne d'Arc, Mahomet, Peter the Great, Napoleon I—were surrounded with a nimbus by the more or less blind belief of the people in their genius; this frequently acted with suggestive power upon the surrounding company which it carried away with a magic force to its leaders, and supported and aided the mission historically vested in the latter by means of their spiritual superiority. A nod from a beloved leader of any army is sufficient to enkindle anew the courage of the regiment and to lead them irresistibly into sure death.
Many, it is well known, are still inclined to deny the individual personality any influence upon the course of historic events. The individual is to them only an expression of the views of the mass, an embodiment of the epoch, something, therefore, that cannot actively strike at the course of history; he is much rather himself heaved up out of the mass by historic events, which, unaffected by the individual, proceed in the courses they have themselves chosen.
We forget in such a theory the influences of the suggestive factors which, independently of endowments and of energy, appear as a mighty lever in the hands of the fortunately situated nature and of those created to be the rulers of the masses. That the individual reflects his environment and his time, that the events of world-history only take their course upon an appropriately prepared basis and under appropriately favorable circumstances, no one will deny. There rests, however, in the masters of speech and writing, in the demagogues and the favorites of the people, in the great generals and statesmen, an inner power which welds together the masses for battle for an ideal, sweeps them away to heroism, and fires them to do deeds which leave enduring impressions in the history of humanity.
