One of the goals of philosophy is wage theoretical battle. That is why we can say that every thesis is always, by its very nature, an antithesis. A thesis is only ever put forward in opposition to another thesis, or in defence of a new one.

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.

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

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.

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.

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