"Friday aftn." "I like Wittgenstein more and more. He has the theoretical passion very strongly—it is a rare passion and one is glad to find it. He doesn't want to prove this or that, but to find out how things really are. He is very excitable and rather mad, but has excellent manners—though in argument he forgets about manners [manner? names?] and simply says what he thinks. In spite of it all, something about him makes him a hero[?]. In his flat moments, he still talks, slowly, stammering, and saying dull things. But at his best he is splendid. There's much more in him than in any of my other pupils."
