Postmodernism is a cargo cult. It seeks to duplicate the form of rational inquiry, while lacking the substance. It's children dressing up in parents' clothes, and complaining about things they don't understand,
like taxes and sciatica, for no better reason than that is what they see adults doing with their time. Monkey see, monkey do.
Postmodernists believe that if they make their terminology sufficiently obscurantist, sesquipedalian, and circumloquatious, nobody
will notice the lack of substance. To a large extent, they are correct in that belief.
Some postmodern philosophers (
like Baudrillard) are beyond help, while others (
like Foucault) are largely salvageable. This must be judged on a case-by-case basis, but not without boots to
wade through the exceedingly
thick bullshit that permeates the entire idea-space.
When you start getting to ideas such as "science is sexist because it probes the natural world (which is the sacred feminine) against its
will, thus committing
rape" it's time to throw the document in the fire. It's important to leave a lot of room around the fire, though, as you've probably underestimated how much pomo literature is totally worthless.
Jack: I just learned about postmodernism in
college, and now I totally believe in it, and self-identify as such.
Jill: You and every other gullible sophomore looking for an intellectual family where you can't possibly be wrong, you
fucking latte-sipping
coward.
