“Mathematics is too arduous and uninviting a field to appeal to those to whom it does not give great rewards. These rewards are of exactly the same character as those of the artist. To see a difficult uncompromising material take living shape and meaning is to be Pygmalion, whether the material is stone or hard, stonelike logic. To see meaning and understanding come where there has been no meaning and no understanding is to share the work of a demiurge. No amount of technical correctness and no amount of labour can replace this creative moment, whether in the life of a mathematician or of a painter or musician. Bound up with it is a judgement of values, quite parallel to the judgement of values that belongs to the painter or the musician. Neither the artist nor the mathematician may be able to tell you what constitutes the difference between a significant piece of work and an inflated trifle; but if he is not able to recognise this in his own heart, he is no artist and no mathematician.”

Context: If humiliation and rejection are to be the rewards of faithful and effective service in this field, what are those of us to conclude who have also served prominently in this line of work but upon whom this badge has not yet been conferred?
We cannot deceive ourselves into believing that it was merit, rather than chance, that spared some of us the necessity of working in areas of activity that have now become controversial, of recording opinions people now find disagreeable, of aiding in the implementation of policies now under question. … In no field of endeavor is it easier than in the field of foreign affairs to be honestly wrong; in no field is it harder for contemporaries to be certain they can distinguish between wisdom and folly; in no field would it be less practicable to try to insist on infallibility as a mark of fitness for office.
