“Think and wonder, wonder and think.”

“I still think it's a wonderful world.”

“That's the point. Every kind of animal thinks its own kind of animal is wonderful. So people getting married think they're wonderful, and that they're going to have a baby-- that's wonderful, when actually they're as ugly as rhinoceroses. Just because we think we're so wonderful doesn't mean we really are. We could be really terrible animals and just never admit it because it would hurt so much.”

“If you stop thinking, if you stop wondering, you die.”

“I used to think that humor was the only way to appreciate how wonderful and terrible the world is, to celebrate how big life is. But now I think the opposite. Humor is a way of shrinking from that wonderful and terrible world.”

“[I] wondered if he was looking up at that same moon, far away, and thinking of me as I was thinking of him.”
