“It is said that man is wolf to man. I find this very unfair to wolves.”

“The intuitive connection children feel with animals can be a tremendous source of joy. The unconditional love received from pets, and the lack of artifice in the relationship, contrast sharply with the much trickier dealings with members of their own species.”

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

“Deep down, creationists realize they will never win factual arguments with science. This is why they have construed their own science-like universe, known as Intelligent Design, and eagerly jump on every tidbit of information that seems to go their way.”

“If you look at human society, it is very easy, of course, to compare our warfare and territoriality with the chimpanzee. But that's only one side of what we do. We also trade, we intermarry, we allow each other to travel through our territory. There's an enormous amount of cooperation.”

“The enemy of science is not religion. Religion comes in endless shapes and forms... The true enemy is the substitution of thought, reflection, and curiosity with dogma.”

“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 smell, the animals know exactly what they are going for. Vision is secondary.”

“The term 'alpha female' originated in my field of animal behavior, but has acquired new meaning. It refers to women who are in charge, for example, by flirting and dating on their own terms. It is also used maliciously for a loud-mouthed, controlling woman who has no patience with deviating opinions.”

“Experiments with animals have long been handicapped by our anthropocentric attitude: We often test them in ways that work fine with humans but not so well with other species.”

“Without agreement on rank and a certain respect for authority there can be no great sensitivity to social rules, as anyone who has tried to teach simple house rules to a cat will agree.”

“Ironically, torture requires empathy, too, in the sense that one cannot deliberately inflict pain without realizing what is painful.”
