A knowledge of the laws relating to the psychology of crowds is indispensable to the interpretation of the elements of our Revolution, and to a comprehension of the conduct of revolutionary assemblies, and the singular transformations of the individuals who form part of them. Pushed by the unconscious forces of the collective soul, they more often than not say what they did not intend, and vote what they would not have wished to vote. Although the laws of collective psychology have sometimes been divined instinctively by superior statesmen, the majority of Governments have not understood and do not understand them. It is because they do not understand them that so many of them have fallen so easily. When we see the facility with which certain Governments were overthrown by an insignificant riot--as happened in the case of the monarchy of Louis-Philippe--the dangers of an ignorance of collective psychology are evident. The marshal in command of the troops in 1848, which were more than sufficient to defend the king, certainly did not understand that the moment he allowed the crowd to mingle with the troops the latter, paralysed by suggestion and contagion, would cease to do their duty. Neither did he know that as the multitude is extremely sensible to prestige it needs a great display of force to impress it, and that such a display will at once suppress hostile demonstrations. He was equally ignorant of the fact that all gatherings should be dispersed immediately. All these things have been taught by experience, but in 1848 these lessons had not been grasped. At the time of the great Revolution the psychology of crowds was even less understood. 2. How the Stability of the Racial Mind limits the Oscillations of the Mind of the Crowd. A people can in a sense be likened to a crowd. It possesses certain characteristics, but the oscillations of these characteristics are limited by the soul or mind of the race. The mind of the race has a fixity unknown to the transitory mind of the crowd. When a people possesses an ancestral soul established by a long past the soul of the crowd is always dominated thereby. A people differs from a crowd also in that it is composed of a collection of groups, each having different interests and passions. In a crowd properly so-called--a popular assembly, for example--there are unities which may belong to very different social categories. A people sometimes seems as mobile as a crowd, but we must not forget that behind its mobility, its enthusiasms, its violence and destructiveness, the extremely tenacious and conservative instincts of the racial mind persist. The history of the Revolution and the century which has followed shows how the conservative spirit finally overcomes the spirit of destruction. More than one system of government which the people has shattered has been restored by the people.
