And I thought how sad it was that, for all our sophisticated intellect, for all our noble aspirations, our aggressive behavior was not just similar in many ways to that of the chimpanzees - it was even worse. Worse because human beings have the potential to rise above their baser instincts, whereas chimpanzees probably do not.

I shouldn't have named the chimps. It wasn't scientific. I didn't know. I knew nothing. And worse sin of all was that I was ascribing to them emotions like happiness, sadness and so forth.

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.

It may sound trite, but young people really are the future.

One cannot watch chimpanzee infants for long without realizing that they have the same emotional need for affection and reassurance as human children.

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

I love to write - it is a great source of reflection, especially as I continue to meet many new inspiring people.
