There is no power relation without the correlative constitution of a field of knowledge, nor any knowledge that does not presuppose and constitute at the same time power relations
Michel FoucaultWhat is peculiar to modern societies is not that they consigned sex to a shadow existence, but that they dedicated themselves to speaking of it ad infinitum, while exploiting it as the secret.
Michel Foucault... we are obliged to produce the truth by the power that demands truth and needs it in order to function: we are constrained, we are condemned to admit the truth or to discover it. Power constantly asks questions and questions us; it constantly investigates and records; it institutionalizes the search for the truth, professionalizes it, and rewards it. ... In a different sense, we are also subject to the truth in the sense that truth lays down the law: it is the discourse of truth that decides, at least in part; it conveys and propels effects of power.
Michel Foucault[T]hus one should not think that desire is repressed, for the simple reason that the law is what constitutes both desire and the lack on which it is predicated. Where there is desire, the power relation is already present: an illusion, then, to denounce this relation for a repression exerted after the event.
