The task is not just to understand the world but to change it.

Men make their own history

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.

Misery motivates, not utopia.

An object of art creates a public capable of finding pleasure in its beauty. Production, therefore, not only produces an object for the subject, but also a subject for the object.

History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.

The bourgeoisie cannot exist without constantly revolutionizing the instruments of production, and thereby the relations of production, and with them the whole relations of society.
