“Evolution is so creative. That's how we got giraffes.”

“No matter what is doing the creating, I have to say that the giraffe and the rhinoceros are ridiculous.”

“I've often thought there ought to be a manual to hand to little kids, telling them what kind of planet they're on, why they don't fall off it, how much time they've probably got here, how to avoid poison ivy, and so on. I tried to write one once. It was called Welcome to Earth. But I got stuck on explaining why we don't fall off the planet. Gravity is just a word. It doesn't explain anything. If I could get past gravity, I'd tell them how we reproduce, how long we've been here, apparently, and a little bit about evolution. I didn't learn until I was in college about all the other cultures, and I should have learned that in the first grade. A first grader should understand that his or her culture isn't a rational invention; that there are thousands of other cultures and they all work pretty well; that all cultures function on faith rather than truth; that there are lots of alternatives to our own society. Cultural relativity is defensible and attractive. It's also a source of hope. It means we don't have to continue this way if we don't like it.”

“I was taught that the human brain was the crowning glory of evolution so far, but I think it's a very poor scheme for survival. ”

“Then again, I am a monopolar depressive descended from monopolar depressives. That's how come I write so good.”

“Our government's got a war on drugs. That's certainly better then no drugs at all.”

“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.”
