The enemy of science is not religion... . The true enemy is the substitution of thought, reflection, and curiosity with dogma.

Most men probably wouldn't want to live the lives of bonobos. They're constantly clinging to their mothers' apron strings. They lack the ability to make decisions about their own fates, something that we and male chimpanzees practically consider our birthright.

I was raised Catholic. Not just a little bit Catholic, like my wife, Catherine. When she was young, many Catholics in France already barely went to church, except for the big three: baptism, marriage, and funeral. And only the middle one was by choice.

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. That is why a severed octopus arm may crawl on its own and even pick up food.

We would much rather blame nature for what we don't like in ourselves than credit it for what we do like.

Morality, after all, has nothing to do with selflessness. On the contrary, self-interest is precisely the basis of the categorical imperative.

I've argued that many of what philosophers call moral sentiments can be seen in other species. In chimpanzees and other animals, you see examples of sympathy, empathy, reciprocity, a willingness to follow social rules. Dogs are a good example of a species that have and obey social rules; that's why we like them so much, even though they're large carnivores.
