Just as houses are made of stones, so is science made of facts.

Point set topology is a disease from which the human race will soon recover.

It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.

There are no solved problems; there are only problems that are more or less solved.

The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

Doubt everything or believe everything: these are two equally convenient strategies. With either we dispense with the need for reflection.

It is through science that we prove, but through intuition that we discover.

Geometry is the art of correct reasoning from incorrectly drawn figures.

One geometry cannot be more true than another; it can only be more convenient.

It is far better to foresee even without certainty than not to foresee at all.

Perhaps I write for no one. Perhaps for the same person children are writing for when they scrawl their names in the snow.

No one knows where we are going, the aim of life has been forgotten, the end has been left behind. Man has set out at tremendous speed- to go nowhere.

All war aims for impunity.

I'm always looking over my shoulder, needing to stay ahead of the game.

When I was 7, my proudest possession would have been my bookshelf - 'cause I'd alphabetized all of the books on my bookshelf.
