In this lecture, we will consider the origins of deconstruction in the theories of Derrida, particularly as they were first presented to America in his (in)famous lecture, "Structure, Sign and Play in the Discourse of the Human Sciences" (1966). We shall see how Derrida, rather than work within the binaries of traditional metaphysics (or logocentrism), attempted to break down (or deconstruct) all such binaries. We shall contrast deconstruction from both Platonic and Christian thought and seek to understand the main terminology associated with deconstruction.
