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.

Lasting change is a series of compromises. And compromise is all right, as long your values don't change.

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

I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other's company.

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 have found that to love and be loved is the most empowering and exhilarating of all human emotions.

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