"Sunday night" "Whitehead (whom I found alone, as Mrs. Whitehead is ill in bed) has been telling me that my mind has improved very greatly the last two or three years, that in fact it has risen to an altogether higher class. He says I used to have great ingenuity in defending rather narrow and limited points of view, but now I have an altogether broader scope, and that if my present work develops as it promises, it will put me among the few great philosophers."

"Having the stimulus of Wittgenstein...."

"I wrote to Wittgenstein, and I hope he will relent."
