And if there were a God, I think it very unlikely that He would have such an uneasy vanity as to be offended by those who doubt His existence - Bertrand Russell

Only in thought is man a God; in action and desire we are the slaves of circumstance.

Philosophy, for Plato, is a kind of vision, the 'vision of truth' ... Everyone who has done any kind of creative work has experienced, in a greater or less degree, the state of mind in which, after long labour, truth or beauty appears, or seems to appear, in a sudden glory – it may only be about some small matter, or it may be about the universe ... I think most of the best creative work, in art, in science, in literature, and in philosophy, has been the result of such a moment.

I do not myself think there is any superior rationality in being unhappy. The wise man will be as happy as circumstances permit, and if he finds contemplation of the universe painful beyond a point, he will contemplate something else instead.
