There was a limit to how far I would go in imposing on Einstein, but I recall going to tell him about the work that Richard Feynman was doing on quantum theory. I outlined the general idea in half an hour, and at the end I said "Don't you think that's beautiful, Professor Einstein, and doesn't this make you ready to believe quantum theory?" "Oh," he said, "I still can't believe God plays dice." But then he added one more sentence; "But maybe I've earned the right to make my mistakes." So he was very much a man who pursued his own course undeflected by others. I don't think I ever saw him deflected by anybody else. I'll have to go back and look up a paper that he wrote with Pauli, Wolfgang Pauli, I think it was about at the end of World War II; it was a paper where they talked about an orbit of a particle going round a center of attraction -- could it keep going and going for ever? I think that might have been designed as an escape from capture from a black hole without ever mentioning the word[s] black hole and without ever mentioning the word capture. I want to see what the motivation of the paper was, if there's any clue to that.
