Ludwig Wittgenstein
Cambridge Apostles

The economist John Maynard Keynes also invited him to join the Cambridge Apostles, an elite secret society formed in 1820, which both Bertrand Russell and G. E. Moore had joined as students, but Wittgenstein did not greatly enjoy it and attended only infrequently. Russell had been worried that Wittgenstein would not appreciate the group's raucous style of intellectual debate, its precious sense of humour, and the fact that the members were often in love with one another. He was admitted in 1912 but resigned almost immediately because he could not tolerate the style of discussion. Nevertheless, the Cambridge Apostles allowed Wittgenstein to participate in meetings again in the 1920s when he had returned to Cambridge. Reportedly, Wittgenstein also had trouble tolerating the discussions in the Cambridge Moral Sciences Club.
