Science may set limits to knowledge, but should not set limits to imagination.

It is because modern education is so seldom inspired by a great hope that it so seldom achieves great results.

It appeared to me obvious that the happiness of mankind should be the aim of all action, and I discovered to my surprise that there were those who thought otherwise.

Most of the greatest evils that man has inflicted upon man have come through people feeling quite certain about something which, in fact, was false.

Mathematics, rightly viewed, possesses not only truth, but supreme beauty a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the georgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.

No matter how eloquently a dog may bark, he cannot tell you that his parents were poor, but honest.

I hold all knowledge that is concerned with things that actually exist - all that is commonly called Science - to be of very slight value compared to the knowledge which, like philosophy and mathematics, is concerned with ideal and eternal objects, and is freed from this miserable world which God has made.
