Probably 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 FoucaultWe 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 FoucaultYou may have killed God beneath the weight of all that you have said; but don't imagine that, with all that you are saying, you will make a man that will live longer than he.
