I am grateful that I am not as judgmental as all those censorious, self-righteous people around me. In each of us there is a little of all of us.

In the world we live in, one fool makes many fools, but one sage only a few sages.

Man is a masterpiece of creation . . .

I have often noticed that when people come to understand a mathematical proposition in some other way than that of the ordinary demonstration, they promptly say, "Oh, I see. That's how it must be." This is a sign that they explain it to themselves from within their own system.

All mathematical laws which we find in Nature are always suspect to me, in spite of their beauty. They give me no pleasure. They are merely auxiliaries. At close range it is all not true.

Honest unaffected distrust of human abilities under all circumstances is the surest sign of strength of mind.

Do not judge God's world from your own. Trim your own hedge as you wish and plant your flowers in the patterns you can understand, but do not judge the garden of nature from your little window box.
