"In the social science that seeks to explain the world as it is, to show how the world works, power is the keystone of all categories, so that, in spite of (indeed, because of) its proclaimed neutrality, this social science participates actively in the separation of subject and object which is the substance of power. To us, power is of interest only in so far as it helps us to understand the challenge of anti-power: the study of power on its own, in abstraction from the challenge and project of anti-power, can do nothing but actively reproduce power."
