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.

Ideology represents the imaginary relationship of individuals to their real conditions of existence.

In truth, ideology has very little to do with 'consciousness', even supposing this term to have an unambiguous meaning. It is profoundly unconscious, even when it presents itself in a reflected form.

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.
