From the idea that the self is not given to us, I think there is only one practical consequence: we have to create ourselves as a work of art.
Michel FoucaultRelations of power "are indissociable from a discourse of truth, and they can neither be established nor function unless a true discourse is produced, accumulated, put into circulation, and set to work. Power cannot be exercised unless a certain economy of discourses of truth functions in, on the basis of, and thanks to, that power."
Michel FoucaultPower is tolerable only on condition that it mask a substantial part of itself. Its success is proportional to its ability to hide its own mechanisms.
