You must act with all energy. Mass searches. Execution for concealing arms. - Vladimir Lenin

The economic basis for the complete withering away of the state is such a high stage of development of communism at which the antithesis between mental and physical labour disappears, at which there consequently disappears one of the principal sources of modern social quality - a source, moreover, which cannot on any account be removed immediately by the mere conversion of the means of production into public property, by the mere expropriation of the capitalists.

Those who are really convinced that they have made progress in science would not demand freedom for the new views to continue side by side with the old, but the substitution of the new views for the old.

If the world is eternally moving and developing matter (as the Marxists think), reflected by the developing human consciousness, what is there “static” here? The point at issue is not the immutable essence of things, or an immutable consciousness, but the correspondence between the consciousness which reflects nature and the nature which is reflected by consciousness.
