How insidious Nature is when one is trying to get at it experimentally.

I admit that thoughts influence the body.

The music of Mozart is of such purity and beauty that one feels he merely found it - that it has always existed as part of the inner beauty of the universe waiting to be revealed.

Intelligence makes clear to us the interrelationship of means and ends. But mere thinking cannot give us a sense of the ultimate and fundamental ends.

Women always worry about things that men forget; men always worry about things women remember.
