The total subject of mathematics is clearly too broad for any of us. I do not think that any mathematician since Gauss has covered it uniformly and fully; even Hilbert did not and all of us are of considerably lesser width quite apart from the question of depth than Hilbert.

If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.

Technological possibilities are irresistible to man. If man can go to the moon, he will. If he can control the climate, he will.

You don't have to be responsible for the world that you're in.

Truth is much too complicated to allow anything but approximations.

The most vitally characteristic fact about mathematics is, in my opinion, its quite peculiar relationship to the natural sciences, or more generally, to any science which interprets experience on a higher than purely descriptive level.
