Time and space are modes by which we think and not conditions in which we live.

I do not much believe in education. Each person ought to be his or her own model, however frightful that may be.

Nothing happens until something moves.

People should be more like animals . . . they should be more intuitive; they should not be too conscious of what they do while they do it.

It's not that I'm so smart.
