I found this on the twitter feed of a young proudly high-brow literary academic who makes carefully thought-out, precise distinctions between "good" and "bad" postmodernism, and good and bad elitism. He drops a lot of names but he's read them all, many in the original. He's not pretentious because he's not pretending; his erudition isn't fakery, but he wants it to carry more weight than it does.

The video is filed under "good". I've watched it 5 or 6 times, laughing every time; that doesn't answer the question of how it came to be, what categories it fits in, and why.

About me
"I am a fit. Welsh-speaking septuagenarian who jogs and works out and can act anything over 60 (and perhaps just a little below that, too). I particularly enjoy Shakespeare, classical drama and voice-over, but will go anywhere, do anything so long as it's acting and legal."
