"Sunday mg." "... Whitehead arrived at 11 and stayed till nearly 5—we discussed work the whole time, very profitable and very enjoyable." A German turned up—"he and Wittgenstein used to come together, and I remember at first I thought them both foolish, and only gradually discovered that Wittgenstein was mad but not foolish."

"Today I got my fifth lecture finally finished, so now I have only three more to re-write."

"My last year here Wittgenstein took up all my time and energy, but this year I shall get at many more people."
