Chimps are far too much human to be my favorite animal.

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

Of course animals have a personality and emotions.

I sometimes wonder how some people can live with themselves in some of the big companies today. So many far-reaching decisions are based on how they will affect the next shareholders' meeting.

It has actually been suggested that warfare may have been the principle evolutionary pressure that created the huge gap between the human brain and that of our closest living relatives, the anthropoid apes. Whole groups of hominids with inferior brains could not win wars and were therefore exterminated.

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

I'm always pushing for human responsibility. Given that chimpanzees and many other animals are sentient and sapient, then we should treat them with respect.
