“The critical ontology of ourselves … has to be conceived as an attitude, an ethos, a philosophical life in which the critique of what we are is at one and the same time the historical analysis of the limits that are imposed on us and an experiment with the possibility of going beyond them” (Foucault, What is Enlightenment?)
“A critique is not a matter of saying that things are not right as they are. It is a matter of pointing out on what kinds of assumptions, what kinds of familiar, unchallenged, unconsidered modes of thought the practices that we accept rest” (Foucault, interview by Didier Eribon, 1981 May 30-31, in Politics, Philosophy, Culture).
“The images of madness are only dream and error, and if the sufferer who is blinded by them appeals to them, it is only to disappear with them in the annihilation to which they are fated” (Foucault, Madness and Civilization).
“Do not ask who I am and do not ask me to remain the same: leave it to our bureaucrats and our police to see that our papers are in order. At least spare us their morality when we write” (Foucault, The Archaeology of Knowledge).
