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.

The economic class struggle is a struggle against inessanlty intensified exploitation: not only against the brutal material form of exploitation, capitalism's tendency to reduce wages, and against the class 'techniques' for increasing productivity... but also around the question of the technical-social division of labor that prevails om enterprises, and against bourgeois ideology and repression.

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.

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.

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.

To philosophize with open eyes is to philosophize in the dark. Only the blind can look straight at the sun.

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