We should not be content to say that power has a need for such-and-such a discovery, such-and-such a form of knowledge, but we should add that the exercise of power itself creates and causes to emerge new objects of knowledge and accumulates new bodies of information. ... The exercise of power perpetually creates knowledge and, conversely, knowledge constantly induces effects of power. ... It is not possible for power to be exercised without knowledge, it is impossible for knowledge not to engender power.
Michel FoucaultProbably it's insufficient to say that behind the governments, behind the apparatus of the State, there is the dominant class; one must locate the point of activity, the places and forms in which its domination is exercised. And because this domination is not simply the expression in political terms of economic exploitation, it is its instrument and, to a large extent, the condition which makes it possible; the suppression of the one is achieved through the exhaustive discernment of the other.
Michel Foucault[John Boswell] introduction of the concept of "gay" (in the way he defines it) provides us both with a useful instrument of research and at the same time a better comprehension of how people actually conceive of themselves and their sexual behavior.
Michel FoucaultA way of life can be shared among individuals of different ages, status, and social activity. It can yield intense relations not resembling those that are institutionalized. It seems to me that a way of life can yield a culture and an ethics. To be "gay," I think, is not to identify with the psychological traits and the visible masks of the homosexual but to try and define and develop a way of life.
Michel FoucaultBut 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.
