Farm animals feel pleasure and sadness, excitement and resentment, depression, fear, and pain. They are far more aware and intelligent than we ever imagined...they are individuals in their own right.

Chimpanzees have given me so much. The long hours spent with them in the forest have enriched my life beyond measure. What I have learned from them has shaped my understanding of human behavior, of our place in nature.

Empathy is really important.. Only when our clever brain and our human heart work together in harmony can we achieve our full potential.

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.

I would never say I was an icon, but so many people have said I am, so I suppose I am. I mean, I can't not be what everyone says I am. But I don't feel like an icon.

I've always felt you don't have to be completely detached, emotionally uninvolved to make precise observations. There's nothing wrong with feeling great empathy for your subjects.

...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?
