Let me start with an apparent aside. In the midst of his dialectical demolition of Foucault’s Histoire de la folie, in “Cogito et histoire de la folie,” Derrida argues that although Foucault wants to do an archeology of madness’s silence, an archeo-logy is a logically ordered work (465), and that even though Foucault wants to protest against reason’s sequestration of madness, “reason in the classical age” can only be brought before the tribunal of Reason in general (466), which could then rule on the unreasonableness of classical reason.
