There are periods in the life of human society when revolution becomes an imperative necessity, when it proclaims itself as inevitable. New ideas germinate everywhere, seeking to force their way into the light, to find an application in life; everywhere they are opposed by the inertia of those whose interest it is to maintain the old order; they suffocate in the stifling atmosphere of prejudice and traditions. The accepted ideas of the constitution of the State, of the laws of social equilibrium, of the political and economic interrelations of citizens, can hold out no longer against the implacable criticism which is daily undermining them whenever occasion arises,--in drawing room as in cabaret, in the writings of philosophers as in daily conversation. Political, economic, and social institutions are crumbling; the social structure, having become uninhabitable, is hindering, even preventing the development of the seeds which are being propagated within its damaged walls and being brought forth around them.
