“I first saw Wittgenstein in the Michaelmas term of 1938, my first term at Cambridge. At a meeting of the Moral Science Club, after the paper for the evening was read and the discussion started, someone began to stammer a remark. He had extreme difficulty in expressing himself and his words were unintelligible to me. I whispered to my neighbour, ‘Who is that?’: he replied, ‘Wittgenstein.’ I was astonished, because, for one reason I had expected the famous author of the Tractatus Logico-Philosophicus to be an elderly man, whereas this man looked young—perhaps about 35. (His actual age was 49.) His face was lean and brown, his profile was aquiline and strikingly beautiful, his head was covered with a curly mass of brown hair. I observed the respectful attention that everyone in the room paid to him. After his unsuccessful beginning he did not speak for a time but was obviously struggling with his thoughts. His look was concentrated, he made striking gestures with his hands as if he were discoursing. All the others maintained an intent and expectant silence. I witnessed this phenomenon count less times thereafter and came to regard it as entirely natural.”
