6 The general form of the truth-function is: [p, ξ, N(ξ)]. This is the general form of proposition.
Among the friendships Wittgenstein makes with Cambridge undergraduates is Gilbert Pattisson. Gilbert is a genial fellow, completes his studies with a miminum of effort or commitment, becomes a municipal accountant. He and Wittgenstein never discuss philosophy.

Ray Monk: "Wittgenstein's correspondence with Pattisson consists almost entirely of 'nonsense.' In nearly every letter he makes some use of the English adjective 'bloody,' which he found inexhaustibly funny. He would begin his letters 'Dear Old Blood' and end them 'Yours bloodily' or 'Yours in bloodiness.'"

The two parody the language of fatuous art criticism, unctuous advertisers. Pattisson sends a picture of himself, writes on the back "On the other side is pictured one of our 47/6 suits." Wittgenstein replies: "You may through my generosity one of these days get a free sample of Glostora the famous hair oil, may your hair always retain that gloss which is so characteristic for well groomed gentlemen."

When Wittgenstein visits London, they always have tea at Lyons and see a film, an American western or musical if possible, at one of the cavernous cinemas in Leicester Square.
