The Socialist and Communist systems properly so called, those of St. Simon, Fourier, Owen and others, spring into existence in the early undeveloped period, described above, of the struggle between proletariat and bourgeoisie (see: Section I , Bourgeoisie and Proletariat .)

The founders of these systems see, indeed, the class antagonisms as well as the action of the decomposing elements in the prevailing form of society. But the proletariat, as yet in its infancy, offers to them the spectacle of a class without any historical initiative or any independent political movement.
