"Wittgenstein on the other hand is rather a severe critic of my lectures—he says I make things seem too simple and easy, and encourage the dogmatic discipleship which I deplore. W. is very excitable: he has more passion about philosophy than I have; his avalanches make mine seem mere snowballs. He has the pure intellectual passion in the highest degree: it makes me love him. His disposition is that of an artist, intuitive and moody. He says every morning he begins his work with hope, and every evening he ends in despair—he has just the sort of rage when he can't understand things that I have."
