We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts. We can and we do. This is what sets us apart from the chimps. They are extremely brutal and hostile. Your next door neighbor is to be killed unless she is a juicy young female, who hasn't yet had her first baby, in which case you want her.

Never be arrogant or abrasive. Treat your opponent respectfully if they really and truly believe they are right.

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.

Our brain is almost the same as the chimps', but we have language, we have electronic communications, we've put people on the moon - we are immensely more intelligent. And yet: how come the being with the most extraordinary intellect ever is destroying its only planet?

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

...it honestly didn't matter how we humans got to be the way we are, whether evolution or special creation was responsible. What mattered and mattered desperately was our future development. Were we going to go on destroying God's creation, fighting each other, hurting the other creatures of the His planet?

Anyone who tries to improve the lives of animals invariably comes in for criticism from those who believe such efforts are misplaced in a world of suffering humanity.
