The facts recalled in this chapter must not be forgotten if we wish fully to comprehend the various roles of the people during revolution. Its action is considerable, but very unlike that imagined by the legends whose repetition alone constitutes their vitality.

THE FORMS OF MENTALITY PREVALENT DURING REVOLUTION
CHAPTER I
INDIVIDUAL VARIATIONS OF CHARACTER IN TIME OF REVOLUTION

1. Transformations of Personality.

I have dwelt at length elsewhere upon a certain theory of character, without which it is absolutely impossible to understand divers transformations or inconsistencies of conduct which occur at certain moments, notably in time of revolution. Here are the principal points of this theory:

Every individual possesses, besides his habitual mentality, which, when the environment does not alter, is almost constant, various possibilities of character which may be evoked by passing events.

The people who surround us are the creatures of certain circumstances, but not of all circumstances. Our ego consists of the association of innumerable cellular egos, the residues of ancestral personalities. By their combination they form an equilibrium which is fairly permanent when the social environment does not vary. As soon as this environment is considerably modified, as in time of insurrection, this equilibrium is broken, and the dissociated elements constitute, by a fresh aggregation, a new personality, which is manifested by ideas, feelings, and actions very different from those formerly observed in the same individual. Thus it is that during the Terror we see honest bourgeois and peaceful magistrates who were noted for their kindness turned into bloodthirsty fanatics.

Under the influence of environment the old personality may therefore give place to one entirely new. For this reason the actors in great religious and political crises often seem of a different essence to ourselves; yet they do not differ from us; the repetition of the same events would bring back the same men.
