“The whole reason people fill their homes with furry carnivores and not with, say, iguanas and turtles, is because mammals offer something no reptile ever will. They give affection, they want...”

“A chimpanzee who is really gearing up for a fight doesn't waste time with gestures but just goes ahead and attacks.”

“Popular culture bombards us with examples of animals being humanized for all sorts of purposes, ranging from education to entertainment to satire to propaganda. Walt Disney, for example, mad...”

“Unlike the primate hand, the elephant's grasping organ is also its nose. Elephants use their trunks not only to reach food but also to sniff and touch it. With their unparalleled sense of sm...”

“I think we need to start thinking about grounding our moral systems in our biology.”

“Our brains have been designed to blur the line between self and other. It is an ancient neural circuitry that marks every mammal, from mouse to elephant.”

“Octopuses have hundreds of suckers, each one equipped with its own ganglion with thousands of neurons. These 'mini-brains' are interconnected, making for a widely distributed nervous system....”

“After World War II it was decided that, in order to prevent the Germans and the French from having another war, it would be better to tie them together into one economic pact so they would i...”

“I was too restless as a boy to sit through an entire mass. It was akin to aversion training. I looked at it like a puppet show with a totally predictable story line. The only aspect I really...”
