Postmodernism as the Vindication of Modernism

I have sometimes said that Postmodernism vindicates Modernity. Here's what I mean (with thanks to Frederick Bauerschmidt): Modernity is a quest for autonomy and freedom. It accomplishes this, in part, by elevating reason which, in turn, elevates the hard sciences. Postmodernity, hating any metanarrative, especially one that purports to be neutral and verifiable like the knowledge of the hard sciences, throws down these things that are elevated. As such, there is no overarching story in which the individual must find themselves limited. There is complete unfettered freedom.
