I can hardly keep track of the things I don't know, but every now and then comes an ignorance that makes me nostalgic.

A man is never astonished that he doesn't know what another does, but he is surprised at the gross ignorance of the other in not knowing what he does.

If there's one thing every good novelist understands, it's that our inner world is unreliable and yet there's no getting beyond it. Every sense is subject to deception, including the moral sense. What seems at first like the hard surface of spiritual reality is really fathomless when you dive down into it. There is no bottom. We neve know anything for sure. (p. xvi)

Knowledge is justice

I may be smart, but I'm not knowledgeable.

Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.
