A great prison structure was planned, whose different levels would correspond exactly to the levels of the centralized administration. The scaffold, … - Michel Foucault

All these present struggles revolve around the question: Who are we? They are a refusal of these abstractions, of economic and ideological state violence, which ignore who we are individually, and also a refusal of a scientific or administrative inquisition which determines who one is.

There are moments in life where the question of knowing whether one might think otherwise than one thinks and perceive otherwise than one sees is indispensable if one is to continue to observe or reflect... What is philosophy today... if it does not consist in, instead of legitimizing what we already know, undertaking to know how and how far it might be possible to think otherwise?... The ‘essay’ —which must be understood as a transforming test of oneself in the play of truth and not as a simplifying appropriation of someone else for the purpose of communication—is the living body of philosophy, if, at least, philosophy is today still what it was once, that is to say, an askesis, an exercise of the self, in thought.

To say that madness is dazzlement is to say that the madman sees the day, the same day that rational men see, as both live in the same light, but that when looking at that very light, nothing else and nothing in it, he sees it as nothing but emptiness, night and nothingness. Darkness for him is another way of seeing the day. Which means that in looking at the night and the nothingness of the night, he does not see at all. And that in the belief that he sees, he allows the fantasies of his imagination and the people of his nights to come to him as realities. For that reason, delirium and dazzlement exist in a relation that is the essence of madness, just as truth and clarity, in their fundamental relation, are constitutive of classical reason.
In that sense, the Cartesian progression of doubt is clearly the great exorcism of madness. Descartes closes his eyes and ears the better to see the true light of the essential day, thereby ensuring that he will not suffer the dazzlement of the mad, who open their eyes and only see night, and not seeing at all, believe that they see things when they imagine them. In the uniform clarity of his closed senses, Descartes has broken with all possible fascination, and if he sees, he knows he really sees what he is seeing. Whereas in the madman's gaze, drunk on the light that is night, images rise up and multiply, beyond any possible self-criticism, since the madman sees them, but irremediably separated from being, since the madman sees nothing.
Unreason is to reason as dazzlement is to daylight.
