Deconstruction and institutions

I just thought this was a good quote--especially when you keep in mind Derrida might have said it in a seminar:

Here I do no more than name... the necessity of a deconstruction. Following the consistency of its logic, it attacks not only the internal edifice, both semantic and formal, of philsophemes [in the French University], but also what one would be wrong to assign to it as its external housing, its extrinsic conditions of practice: the historical formsof its pedagogy, the social, economic or political structures of this pedagogical institution. [And here is the real heart of the quote:] It is because deconstruction interferes with solid structures, "material" institutions, and not only with discourses or signifying representations, that it is always distinct from an analysis or a "critique." [These amount to nothing other than protocols for reading that we need to revisit: who now reads Derrida's efforts to deconstruct really in this way? Did anyone do it then, in 1972?] And in order to be pertinent, deconstruction works as strictly as possible in that place where the supposedly "internal" order of the philosophical is articulated by (internal and external) necessity with the institutional conditions and forms of teaching. To the point where the concept of institution itself would be subjected to the same deconstructive treatment. [And the gesture of acquiescence to supplementarity:] But I am already leading into next years seminar.
