I cannot imagine a God who rewards and punishes the objects of his creation and is but a reflection of human frailty.

I am an absolute pacifist...It is an instinctive feeling. It is a feeling that possesses me, because the murder of men is disgusting.

Many a young lady does not realize just how strong her love for a young man is until he fails to pass the approval test with her parents. There is no fear in love; but perfect love casteth out fear. Of all forms of caution, caution in love is the most fatal. There are only two truly infinite things, the universe and stupidity. And I am unsure about the universe.

Things you can get access to, you should never memorize.

I once thought that if I could ask God one question, I would ask how the universe began, because once I knew that, all the rest is simply equations. But as I got older I became less concerned with how the universe began. Rather, I would want to know why he started the universe. For once I knew that answer, then I would know the purpose of my own life.

I don't teach my students, I provide the circumstances in which they can learn.

I have not eaten enough of the tree of knowledge, though in my profession I am obligated to feed on it regularly.
