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.

If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?

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.

You need to indoctrinate empathy out of people in order to arrive at extreme capitalist positions.

I am personally not against keeping animals at zoos, as they serve a huge educational purpose, but treating them well and with respect seems the least we could do, and with 'we' I mean not just zoo staff, but most certainly also the public.

It is not only visitors to the zoo who are fascinated but uneasy in the presence of chimpanzees; the same is true of scientists. The more they learn about these great apes, the deeper our identity crisis seems to become. The resemblance between humans and chimpanzees is not only external. If we look straight and deep into a chimpanzee’s eyes, an intelligent, self-assured personality looks back at us. If they are animals, what must we be?

Empathy as a complex emotion is different. It requires awareness of the other person's feelings and of one's own reactions. The appropriate reaction may not be to cry when another person cries, but to reassure them, or even to leave them alone.
