“If you look at national economies today, for example, the American economy, the European economy, the Indians, the Chinese, we're all tied together. If one of them sinks, the rest are going to sink with them and if one floats, the rest are lifted up. I find that very interesting.”
“Scientists are supposed to study animals in a totally objective fashion, similar to the way we inspect a rock or measure the circumference of a tree trunk. Emotions are not to interfere with the assessment. The animal-rights movement capitalizes on this perception, depicting scientists as devoid of compassion.”
“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 affection, and respond to our emotions the way we do to theirs.”
“Religions have a strong binding function and a cohesive element. They emphasize the primacy of the community as opposed to the individual, and they also help set one community apart from another that doesn't share their beliefs.”
“Empathy probably started out as a mechanism to improve maternal care. Mammalian mothers who were attentive to their young's needs were more likely to rear successful offspring.”

“Personally, I think it is possible to build a society that is moral on a nonreligious basis, but the jury is still out on that.”
“The primate laugh is given in playful contexts, and as such has a strong similarity to the human laugh.”
“What is the evolutionary value of blushing? It seems not to be to our advantage to do it, to involuntarily reveal our inner emotions. If we're trying to manipulate or lie, actions in furtherance of individual goals as opposed to the goals of others, blushing would not seem to be helpful. And yet everyone blushes, except the psychopath.”
