"Thursday night" "I started filling out Lecture I, and then Wittgenstein arrived—he has decided he must be quite alone to work, so he is going to Norway, giving up Cambridge. I expect he will commit suicide towards the end of the winter, but it can't be helped. He has done admirable work."

"I got a ms paper on space from Whitehead wh. I had to read at once and take to be typed, so I read it with Wittgenstein—it is very good."
