The Seven Self-Contradictions of Postmodernism

[theapportioner]

Well, yes, but you have misunderstood everything.

I won't speak for everyone, but Richard Rorty (the only one you've read, it seems, and probably only from some encyclopedia) DOES NOT reject concepts like truth, science, objectivity, and so on. They have their uses, but their use is dependent on certain precise contexts. The problem is when these concepts are generalized, abstracted away from the context. Rorty (and many others) criticize the ways in which we LEGITIMATE something, say the primacy of science, based on the overgeneralization of these ideas. It is the basis for legitimation that is all wrong. You have to remember that, although Rorty is sympathetic to the ideas of folks like Derrida, that he's also very much part of the analytic philosophy tradition.
