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.

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.'

However much an ideologue tries to bury [Lenin] beneath a proof by historical analysis, there is always this one man standing their on the plain of History and of our lives, in the eternal 'current situation.' He goes on talking, calmly or passionately. He goes on talking about something simple: his revolutionary practice, the practice of class struggle, about what makes it possible to act on history...not to demonstrate that revolutions are inevitable, but to make them in our unique present.

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

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.

In the battle that is philosophy all the techniques of war, including looting and camouflage, are permissible.
