 I would also distinguish myself from para-Marxist like Marcuse who give the notion of repression an exaggerated role—because power would be a fragile thing if its only function were to repress, if it worked only through the mode of censorship, exclusion, blockage and repression, in the manner of a great Superego, exercising itself only in a negative way. If, on the contrary, power is strong this is because, as we are beginning to realize, it produces effects at the level of desire—and also at the level of knowledge. Far from preventing knowledge, power produces it. (Foucault 1980: 59)
