Marxism is the science of the laws governing the development of nature and society, the science of the revolution of the oppressed and exploited masses, the science of the victory of socialism in all countries, the science of building communist society.

But democracy is by no means a limit one may not overstep; it is only one of the stages in the course of development from feudalism to capitalism, and from capitalism to Communism.

In a higher phase of communist society... only then can the narrow horizon of bourgeois right be fully left behind and society inscribe on its banners: from each according to his ability, to each according to his needs.

Communism is the riddle of history solved, and it knows itself to be this solution.

The theory of Communism may be summed up in one sentence: Abolish all private property.

Communism begins where atheism begins.
