Be assured that our individual actions, collectively, make a huge difference.

It's not that humans and non-humans are identical... but the lack of understanding that led to the slave trade is the same lack of understanding many people have about animals today. When slaves were brought over from Africa, many people believed they were not humans, that they didn't have feelings. Many people believe that primates and other animals don't have feelings, too, but they do.

I never wanted to give up. I thought I might have to. Especially at the beginning when chimpanzees had never seen a white person before.They gave one look at me and ran away! They were scared, but eventually I got their trust.

Science demands objective factual evidence - proof; spiritual experience is subjective and leads to faith.

When you meet chimps you meet individual personalities. When a baby chimp looks at you it's just like a human baby. We have a responsibility to them.

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

You cannot share your life with a dog, as I had done in Bournemouth, or a cat, and not know perfectly well that animals have personalities and minds and feelings.
