I cannot believe – and I say this with all the emphasis of which I am capable – that there can ever be any good excuse for refusing to face the evide… - Bertrand Russell

The number of syllables in the English names of finite integers tends to increase as the integers grow larger, and must gradually increase indefinitely, since only a finite number of names can be made with a given finite number of syllables. Hence the names of some integers must consist of at least nineteen syllables, and among these there must be a least. Hence "the least integer not nameable in fewer than nineteen syllables" must denote a definite integer; in fact, it denotes 111, 777. But "the least integer not nameable in fewer than nineteen syllables" is itself a name consisting of eighteen syllables; hence the least integer not nameable in fewer than nineteen syllables can be named in eighteen syllables, which is a contradiction. This contradiction was suggested to us by Mr. G. G. Berry of the Bodleian Library.

Not to be absolutely certain is, I think, one of the essential things in rationality.

What I do maintain is that success can only be one ingredient in happiness,
and is too dearly purchased if all the other ingredients have been sacrificed to obtain
it.
