[...] Deconstruction in this, its most rigorous form acts as a constant reminder of the ways in which language deflects or complicates the philosopher's project. Above all, deconstruction works to undo the idea--according to Derrida, the ruling illusion of Western metaphysics--that reason can somehow dispense with language and arrive at a pure, self-authenticating truth or method. Though philosophy strives to efface its textual or 'written' character, the signs of that struggle are there to be read in its blind-spots of metaphor and other rhetorical strategies.
