What Was Deconstruction? I could never get the hang of deconstruction, I just felt like I could not infer some place to go from what I read: oftentimes I couldn't follow a particular passage of Derrida, or a particular line of thought. It's super dense stuff. But I can give an interpretation of it, just to get at the central question in the title "What Was Deconstruction?"
What I could gather from it though: Heidegger's distinction between the present-at-hand/ready-to-hand is the main distinction that makes sense of Derrida for me. Whereas Heidegger does this phenomenological analysis of language and draws out that the history of metaphysics has, up to him, focused on the present-at-hand at the neglect of the phenomenologically accessible ready-to-hand. -- Derrida instead seems to believe that all philosophy, up to Husserl at least, has been structured by a super-transcendental binary: one that cannot even be named, but which receives many names depending on the philosophy. So you get, in philosophy, these oppositions between presence/absence, material/ideal, good/bad, man/woman, and so forth. (To be fair to Derrida, such oppositions really are quite common)
Deconstruction is supposed to be the method by which we discover this super-transcendental, and perhaps, get to something real and lived, what is between the binary -- the binary is needed, of course, because it makes sense, but upon deconstructing the binary one comes to see what might be "left over". (granted, this is a metaphorical expression of deconstruction -- whether the method works in a particular text is up to the reader/writer, if I'm following correctly)
But also -- the habit, tendency, or solution of the philosophers to make a binary -- that is also in question I believe. However, being the "serious minded" type myself, I think I missed how he did it. Which is why I've talked about play thus far -- it was something that really just occurred to me as I was thinking about these posts.
