Foucault's Attempt to Speak Madness

Derrida: Foucault sought to lend a voice to madness that was not filtered through reason. Derrida is very suspicious of such a possibility, calling it, in his words, an objectivist naivete. So the way that Derrida characterizes that here is an attempt to try and speak madness or let madness speak without filtering it through reason. But in any case, we have this binary between reason and madness.
