“I was walking about in Cambridge and passed a bookshop, and in the window were portraits of Russell, Freud and Einstein. A little further on, in a music shop, I saw portraits of Beethoven, Schubert and Chopin. Comparing these portraits I felt intensely the terrible degeneration that had come over the human spirit in the course of only a hundred years.”
(Wittgenstein to Drury, c 1930)

And if he walked past a bookshop in Cambridge today, doubtless he’d see pictures of Paris Hilton.
