I always loved animals. And when I was ten, I decided I had to go to Africa and live with animals and write books about them.

We are unique. Chimpanzees are unique. Dogs are unique. But we humans are just not as different as we used to think.

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.

From my perspective, I absolutely believe in a greater spiritual power, far greater than I am, from which I have derived strength in moments of sadness or fear. That's what I believe, and it was very, very strong in the forest.

I have never had an animal that didn't have a personality, one differing from another.

Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings.

The greatest danger to our future is apathy.
