Do not think that one has to be sad in order to be militant, even though the thing one is fighting is abominable.

But let there be no misunderstanding: it is not that a real man, the object of knowledge, philosophical reflection or technological intervention, has been substituted for the soul, the illusion of theologians. The man described for us, whom we are invited to free, is already in himself the effect of a subjection more profound than himself. A 'soul' inhabits him and brings him to existence, which is itself a factor in the mastery that power exercises over the body. The soul is the effect and instrument of a political anatomy; the soul is the prison of the body.

Nature, keeping only useless secrets, had placed within reach and in sight of human beings the things it was necessary for them to know.

You know the difference between a real science and a pseudoscience? A real science recognizes and accepts its own history without feeling attacked. When you tell a psychiatrist his mental institution came from a lazar house, he becomes infuriated.

Why shouldn't I be interested in politics? That is to say, what blindness, what deafness, what density of ideology would have to weigh me down to prevent me from being interested in what is probably the most crucial subject to our existence, that is to say the society in which we live, the economic relations within which it functions, and the system of power which defines the regular forms and the regular permissions and prohibitions of our conduct. The essence of our life consists, after all, of the political functioning of the society in which we find ourselves.
