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.

It is these undeniable qualities of human love and compassion and self-sacrifice that give me hope for the future. We are, indeed, often cruel and evil. Nobody can deny this. We gang up on each one another, we torture each other, with words as well as deeds, we fight, we kill. But we are also capable of the most noble, generous, and heroic behavior.

A good mother is protective but not over-protective. She's patient, she's affectionate, she's playful, but above all she is supportive.

We can't leave people in abject poverty, so we need to raise the standard of living for 80% of the world's people, while bringing it down considerably for the 20% who are destroying our natural resources.

Certainly the first true humans were unique by virtue of their large brains. It was because the human brain is so large when compared with that of a chimpanzee that paleontologists for years hunted for a half-ape, half-human skeleton that would provide a fossil link between the human and the ape.

The only possible way to get somebody to change is to reach into their hearts.

I don't even think of chimps as animals. I think of them as beings.
