“Matthey, a Geneva physician very close to Rousseau's influence, formulates the prospect for all men of reason: 'Do not glory in your state, if you are wise and civilized men; an instant suffices to disturb and annihilate that supposed wisdom of which you are so proud; an unexpected event, a sharp and sudden emotion of the soul will abruptly change the most reasonable and intelligent man into a raving idiot.”

“[T]hus one should not think that desire is repressed, for the simple reason that the law is what constitutes both desire and the lack on which it is predicated. Where there is desire, the power relation is already present: an illusion, then, to denounce this relation for a repression exerted after the event.”

“…modern man no longer communicates with the madman […] There is no common language: or rather, it no longer exists; the constitution of madness as mental illness, at the end of the eighteenth century, bears witness to a rupture in a dialogue, gives the separation as already enacted, and expels from the memory all those imperfect words, of no fixed syntax, spoken falteringly, in which the exchange between madness and reason was carried out. The language of psychiatry, which is a monologue by reason about madness, could only have come into existence in such a silence.”

“As soon as you start writing, even if it is under your real name, you start to function as somebody slightly different, as a "writer". You establish from yourself to yourself continuities and a level of coherence which is not quite the same as your real life... All this ends up constituting a kind of neo-identity which is not identical to your identity as a citizen or your social identity, Besides you know this very well, since you want to protect your private life.”

“Are you going to change yet again, shift your position according to the questions that are put to you, and say that the objections are not really directed at the place from which you are speaking? Are you going to declare yet again that you have never been what you have been reproached with being? Are you already preparing the way out that will enable you in your next book to spring up somewhere else and declare as you're now doing: no, no, I'm not where you are lying in wait for me, but over here, laughing at you?' 'What, do you imagine that I would take so much trouble and so much pleasure in writing, do you think that I would keep so persistently to my task, if I were not preparing – with a rather shaky hand – a labyrinth into which I can venture, into which I can move my discourse... in which I can lose myself and appear at last to eyes that I will never have to meet again. I am no doubt not the only one who writes in order to have no face. 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.”

“And now, if we try to assign a value, in and of itself, outside its relations to the dream and with error, to classical unreason, we must understand it not as reason diseased, or as reason lost or alienated, but quite simply as reason dazzled.”

“Discourse is not life; its time is not your time; in it, you will not be reconciled to death; you may have killed God beneath the weight of all that you have said; but don't imagine that, with all that you are saying you will make a man that will live longer than he.”
