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.

Whatseems to take place outside ideology (to be precise, in the street), in reality takes place in ideology. What really takes place in ideology seems therefore to take place outside it. That is why those who are in ideology believe themselves by definition outside ideology: one of the effects of ideology is the practical denegation of the ideological character of ideology by ideology: ideology never says, 'I am ideological.'

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 ultimate condition of production is therefore the reproduction of the conditions of production

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.

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

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