I am of course unable to accept a claim made on behalf of mathe matics to have rationally solved logical and metaphysical problems in a way unintelligible except to the mathematician. And there is one thing only which would incline me to accept such a claim. It would have to be made by a man, who can meet on their own ground the non-mathematical logicians and metaphysicians— can show that he understands and enters into their views and their puzzles — and can inspire the belief that he himself is somehow able better, even outside mathematics, to deal rationally with ultimate problems. But my whole acquaintance with this subject is unfortunately too limited even to justify perhaps what now I have ventured to set down.
