Jacques Derrida, who first presented his theories to an American audience in his (in)famous lecture, "Structure, Sign and Play in the Discourse of the Human Sciences" (1966), seeks to go the structuralists one better. Refusing to invert established binaries, Derrida seeks instead to deconstruct them. We contrast deconstruction with both Platonic and Christian thought, and outline the main terminology associated with post-modern theory.
