Postmodernism isn't science. You're right in that the mediocre stuff will fade and the interesting ideas will remain. Yet I have two counterpoints to offer. First, will postmodernism leave lasting ideas at all? Has its skepticism towards language, for example, led to anything new over what was given to us by Wittgenstein? Second, even if all the dross fades and disappears, isn't it a shame about all those years when it dominated humanities and much of philosophy? What kind of genuinely interesting ideas were never explored because of that domination?
Has its skepticism towards language, for example, led to anything new over what was given to us by Wittgenstein?
This is my question exactly. I would like to see a short intro to postmodernism that starts with Wittgenstein and explains in relatively clear language what new insights it produced. I don't know if it's safe or unsafe to assume that the postmodernists read Wittgenstein.
