During the years 1945-1965 (I am referring to Europe), there was a certain way of thinking correctly, a certain style of politicaldiscourse, a certain ethics of the intellectual. One had to be on familiar terms with Marx, not let one's dreams stray too far from Freud.... These were therequirements that made the strange occupation of writing and speaking a measure of truth about oneself and one's time acceptable.
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.
