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

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

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.'

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 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.

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.

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