“I do not blench at nature red in tooth and claw... And much as I love The Wind in the Willows and the works of Beatrix Potter, I never dress my animals in clothes... They behave as animals should behave, with the exception that they open their mouths and speak the Queen's English.”

“I supposed the Red Guards had enjoyed themselves. Is it not true that we all possess some destructive tendencies in our nature? The veneer of civilization is very thin. Underneath lurks the animal in each of us. If I were young and had had a working class background, if I had been brought up to worship Mao and taught to believe him infalliable, would I not have behaved exactly as the Red Guards had done?”

“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.”

“How absurd these words are, such as beast and beast of prey. One should not speak of animals in that way. They may be terrible sometimes, but they're much more right than men...They're never in any embarrassment. They always know what to do and how to behave themselves. They don't flatter and they don't intrude. They don't pretend. They are as they are, like stones or flowers or stars in the sky.”

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

“Cruelty.Not only the willful causing of unnecessary suffering, but the indifference to it. It's much easier to be cruel than one might think. It's often said that nature, "red in tooth and claw," is cruel. I heard this again and again from ranchers, who tried to persuade me that they were protecting their animals from what lay outside the enclosures. Nature is no picnic, true. (Picnics are rarely picnics.)And it's also true that animals on the very best farms often have better lives than they would in the wild. But nature isn't cruel. And neither are the animals in nature that kill and occasionally even torture one another. Cruelty depends on an understanding of cruelty, and the ability to choose against it. Or to choose to ignore it.”
