"I do not remember at what date Whitehead and I decided that he should have sole charge of the fourth volume of Principia Mathematica on geometry. I should say, at a guess, that it was about 1905. It seemed natural to leave geometry to him as he was working on it and especially interested in it, whereas I was more interested in other parts of our subject."
