As stated before, these interests he found were but the logical product of the material conditions underlying capitalist production: conditions which were bound to make the workers conscious of their class interests, and develop to such a climax where the expropriation of the expropriators would become a dictate of historic evolution: where individual social property would give way to social individual property, as the next step in the dialectical process of social development.
Practically fifty years have elapsed since the publication of the first volume of "Capital," and the formulation of the theories just touched upon. And on March 14th of this year it will be thirty-four years since Karl Marx has passed from us. In these days of hurry and scurry, thirty-four years seem a veritable age. How many refutations, corrections, revisions, and annihilations of Marxism were we not compelled to witness in this short span of time?
