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.

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.

If someone asks, ‘But what in the end is a philosopher?’ I would say ‘A philosopher is a human being who fights in theory.’

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.

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.
