There are some people, nevertheless — and I am one of them — who think that the most practical and important thing about a man is still his view of the universe. ... We think that for a general about to fight an enemy, it is important to know the enemy's numbers, but still more important to know the enemy's philosophy. We think the question is not whether the theory of the cosmos affects matters, but whether in the long run, anything else affects them.
