Michel Foucault, The Essential Foucault: Selections from Essential Works of Foucault, 1954-1984

"The necessity of reform mustn’t be allowed to become a form of blackmail serving to limit, reduce, or halt the exercise of criticism. Under no circumstances should one pay attention to those who tell one: “Don’t criticize, since you’re not capable of carrying out a reform.” That’s ministerial cabinet talk. Critique doesn’t have to be the premise of a deduction that concludes, “this, then, is what needs to be done.” It should be an instrument for those for who fight, those who resist and refuse what is. Its use should be in processes of conflict and confrontation, essays in refusal. It doesn’t have to lay down the law for the law. It isn’t a stage in a programming. It is a challenge directed to what is."
