Young Men Should Prove Theorems, Old Men

Chess Problems Are The Hymn-tunes Of Mathematics.

The Public Does Not Need To Be Convinced That There Is Something In Mathematics.

No Mathematician Should Ever Allow Him To Forget That Mathematics, More Than Any Other Art Or Science, Is A Young Man's Game. ... Galois Died At Twenty-one, Abel At Twenty-seven, Ramanujan At Thirty-three, Riemann At Forty. There Have Been Men Who Have Done Great Work Later; ... [but] I Do Not Know Of A Single Instance Of A Major Mathematical Advance Initiated By A Man Past Fifty. ... A Mathematician May Still Be Competent Enough At Sixty, But It Is Useless To Expect Him To Have Original Ideas.

I Have Never Done Anything 'useful'. No Discovery Of Mine Has Made, Or Is Likely To Make, Directly Or Indirectly, For Good Or Ill, The Least Difference To The Amenity Of The World... Judged By All Practical Standards, The Value Of My Mathematical Life Is Nil; And Outside Mathematics It Is Trivial Anyhow. I Have Just One Chance Of Escaping A Verdict Of Complete Triviality, That I May Be Judged To Have Created Something Worth Creating. And That I Have Created Something Is Undeniable: The Question Is About Its Value.

Most People Have Some Appreciation Of Mathematics, Just As Most People Can Enjoy A Pleasant Tune; And There Are Probably More People Really Interested In Mathematics Than In Music. Appearances Suggest The Contrary, But There Are Easy Explanations. Music Can Be Used To Stimulate Mass Emotion, While Mathematics Cannot; And Musical Incapacity Is Recognized (no Doubt Rightly) As Mildly Discreditable, Whereas Most People Are So Frightened Of The Name Of Mathematics That They Are Ready, Quite Unaffectedly, To Exaggerate Their Own Mathematical Stupidity
