"Marxism has won its historic significance as the ideology of the revolutionary proletariat because, far from rejecting the most valuable achievements of the bourgeois epoch, it has, on the contrary, assimilated and refashioned everything of value in the more than two thousand years of the development of human thought and culture. Only further work on this basis and in this direction, inspired by the practical experience of the proletarian dictatorship as the final stage in the struggle against every form of exploitation, can be recognised as the development of a genuine proletarian culture."

- V.I. Lenin, On Proletarian Culture
