In [great Mathematics] There Is

Reductio Ad Absurdum, Which Euclid Loved So Much, Is One Of A Mathematician's Finest Weapons. It Is A Far Finer Gambit Than Any Chess Play: A Chess Player May Offer The Sacrifice Of A Pawn Or Even A Piece, But A Mathematician Offers The Game.

It Is Not Worth An Intelligent Man's Time To Be In The Majority. By Definition, There Are Already Enough People To Do That.

I Count Maxwell And Einstein, Eddington And Dirac, Among "real" Mathematicians. The Great Modern Achievements Of Applied Mathematics Have Been In Relativity And Quantum Mechanics, And These Subjects Are At Present At Any Rate, Almost As "useless" As The Theory Of Numbers.

If I Could Prove By Logic That You Would Die In Five Minutes, I Should Be Sorry You Were Going To Die, But My Sorrow Would Be Very Much Mitigated By Pleasure In The Proof.

[regarding Mathematics,] There Are Now Few Studies More Generally Recognized, For Good Reasons Or Bad, As Profitable And Praiseworthy. This May Be True; Indeed It Is Probable, Since The Sensational Triumphs Of Einstein, That Stellar Astronomy And Atomic Physics Are The Only Sciences Which Stand Higher In Popular Estimation.
