In considering such revolutions one must constantly distinguish between the industrial revolution, to be carefully posited scientifically, which takes place in the economic conditions of production, and the legal, political, religious, artistic or philosophical, in short ideological, forms wherein men become conscious of this conflict and fight it out. As little as we judge an individual by what he himself thinks he is, just as little can we judge such a revolutionary epoch by its own consciousness. We must rather explain this consciousness out of the antagonisms of men's industrial life, out of the conflict existing between the forces of social production and the relations of social production. A form of society never breaks down until all the productive forces are developed for which it affords room. New and higher relations of production are never established, until the material conditions of life to support them have been prepared in the lap of the old society itself. Therefore mankind always sets for itself only such tasks as it is able to perform; for upon close examination it will always be found that the task itself only arises where the material conditions for its solution are already at hand or are at least in process of growth. We may in broad outlines characterize the Asiatic, the antique, the feudal and the modern capitalist methods of production as progressive epochs in the economic evolution of society. The industrial relations arising out of the capitalistic method of production constitute the last of the antagonistic forms of social production; antagonistic not in the sense of an individual antagonism, but of an antagonism growing out of the social conditions of individuals. But the productive forces which are developed in the lap of capitalistic society create at the same time the material conditions needed for the abolition of this antagonism. The capitalist form of society therefore, brings to a close this prelude to the history of human society."
