Animals have personalities and minds and emotions.

There are good mothers and bad ones, but most of them are somewhere in-between.

I urge you to read Eternal Treblinka and think deeply about its important message.

The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

I had a wonderful teacher about animal behavior - my dog Rusty. He taught me that animals have personalities, minds, and feelings.

There isn't a sharp line dividing humans from the rest of the animal kingdom. All the time, we find animals doing things that, in our arrogance, we thought were just human.

But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.
