We come finally, however, to the relation of the ideal theory to real world, or "real" probability. If he is consistent a man of the mathematical school washes his hands of applications. To someone who wants them he would say that the ideal system runs parallel to the usual theory: "If this is what you want, try it: it is not my business to justify application of the system; that can only be done by philosophizing; I am a mathematician". In practice he is apt to say: "try this; if it works that will justify it".

A Miscellany is a collection without a natual ordering relation.

The surprising thing about this paper is that a man who could write it would.

I listen only to Bach, Beethoven or Mozart. Life is too short to waste on other composers.

The referee said it was not acceptable, but the Press considered they could not refuse to publish a book by a professor of the university.

A good mathematical joke is better, and better mathematics, than a dozen mediocre papers.

It is true that I should have been surprised in the past to learn that Professor Hardy had joined the Oxford Group. But one could not say the adverse chance was 1:10. Mathematics is a dangerous profession; an appreciable proportion of us go mad, and then this particular event would be quite likely.
