It is characteristic of ideology to impose self-evident facts as self-evident facts.

Philosophy is, in the last instance, class struggle in the field of theory.

Without claiming to be exhaustive, I maintain that every philosophy reproduces within itself, in one way or another, the conflict in which it finds itself compromised and caught up in the outside world.

Ideology... is indispensable in any society if men are to be formed, transformed and equipped to respond to the demands of their conditions of existence.

Relations of production are first reproduced by the materiality of the processes of production and circulation. But it should not be forgotten that ideological relations are immediately present in these same processes.

In the battle that is philosophy all the techniques of war, including looting and camouflage, are permissible.

The rejection of all abstract formalism. Materialism reminds every science of its real source: the world men transform. No science can, whether in its history or its object, grasp its own origins within itself or constitute itself as a closed world, exhaustively defined by internal rules. Materialism refers every science and every activity to the reality they depend on, even if this dependence is masked by a great many abstract mediations: mathematics as well as logic, aesthetics as well as ethics and politics.
