It must be added that all the peculiarities of collective mental process mentioned above express themselves very readily in the actions of simple crowds, because such a crowd is incapable of resolution and volition in the true sense of the words. I have shown[28] that individual resolution and volition are only rendered possible by the possession of a well-developed self-consciousness and self-regarding sentiment. But a simple crowd has at the most only a rudimentary self-consciousness and has no self-regarding sentiment. Hence its actions are the direct issue of the various impulses that are collectively evoked; and, though it may be collectively conscious of the end towards which it is impelled, and though all the individuals may desire to effect or realise this end, and to that extent may be said to be capable of purpose; yet such an impulse or desire cannot be steadied, strengthened, renewed, or supported and maintained, in opposition to any other impulse that may come into play, by an impulse springing from the self-regarding sentiment in the way which constitutes resolution and volition. Just so far as the self-regarding sentiment of individuals comes into play and they exert their individual volitions, they cease to act as members of a crowd. The actions of the simple crowd are thus not the outcome of a general will, nor are they the resultant of the wills of all its members; they are simply not volitional in the true sense, but rather impulsive. They are comparable with the actions of an animal rather than with those of a man. It is the lack of the conditions necessary to collective resolution and volition that renders a crowd so fickle and inconsistent; so capable of passing from one extreme of action to another, of hurrying to death the man whom it glorified at an earlier moment, or of turning from savage butchery to tender and tearful solicitude. Such incapacity of the crowd for resolution and volition, together with the increased suggestibility of its members, accounts for the fact that a crowd may be easily induced to follow as a leader any one who, by means of the elementary reasoning processes suited to its intellectual capacity, can succeed in suggesting to it the desirability of any course of action.
