The mentality of the Convention was not homogeneous. Now, an assembly composed of individuals of widely different characters soon splits up into a number of groups. The Convention very early contained three—the Gironde, the Mountain, and the Plain. The constitutional monarchists had almost disappeared.

The Gironde and the Mountain, extreme parties, consisted of about a hundred members apiece, who successively became leaders. In the Mountain were the most advanced members: Couthon, Herault de Sechelles, Danton, Camille Desmoulins, Marat, Collot d'Herbois, Billaud-Varennes, Barras, Saint-Just, Fouche, Tallien, Carrier, Robespierre, &c. In the Gironde were Brissot, Petion, Condorcet, Vergniaud, &c.

The five hundred other members of the Assembly—that is, the great majority—constituted what was known as the Plain.

This latter formed a floating mass, silent, undecided, and timid; ready to follow every impulse and to be carried away by the excitement of the moment. It gave ear indifferently to the stronger of the two preceding groups. After obeying the Gironde for some time it allowed itself to be led away by the Mountain, when the latter triumphed over its enemy. This was a natural consequence of the law already stated, by which the weak invariably fall under the dominion of the stronger wills.

The influence of great manipulators of men was displayed in a high degree during the Convention. It was constantly led by a violent minority of narrow minds, whose intense convictions lent them great strength.

A brutal and audacious minority will always lead a fearful and irresolute majority. This explains the constant tendency toward extremes to be observed in all revolutionary assemblies. The history of the Convention verifies once more the law of acceleration studied in another chapter.

The men of the Convention were thus bound to pass from moderation to greater and greater violence. Finally they decimated themselves. Of the 180 Girondists who at the outset led the Convention 140 were killed or fled, and finally the most fanatical of the Terrorists, Robespierre, reigned alone over a terrified crowd of servile representatives.

Yet it was among the five hundred members of the majority, uncertain and floating as it was, that the intelligence and experience were to be found. The technical committees to whom the useful work of the Convention was due were recruited from the Plain.

More or less indifferent to politics, the members of the Plain were chiefly anxious that no one should pay particular attention to them. Shut up in their committees, they showed themselves as little as possible in the Assembly, which explains why the sessions of the Convention contained barely a third of the deputies.

Unhappily, as often happens, these intelligent and honest men were completely devoid of character, and the fear which always dominated them made them vote for the worst of the measures introduced by their dreaded masters.
