“Man is a clever animal who behaves like an imbecile.”

“...an animal, at the end of a few months, is what it will be all its life; and its species, at the end of a thousand years, is what it was in the first of those thousand years. Why is man alone subject to becoming an imbecile?”

“...In little more than a single century from 1820 to 19450, no less than fifty-nine million human animals were killed in inter-group clashes of one sort or another.... We describe these killings as men behaving "like animals," but if we could find a wild animal that showed signs of acting this way, it would be more precise to describe it as behaving like men.”

“We talk of humans behaving indistinguishably from animals; this view is an insult to animals, as they would not treat other creatures of their own kind the way we at times behave towards each other.”

“Was it possible—was it at all possible that she could come out of her most desperate choice with a man as clever as Odysseus who looked like Achilles and made love like Paris…?”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”
