We could change the world tomorrow if all the millions of people around the world acted the way they believe.

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

Studying chimps, I came to the conclusion that being evil is something that only humans are capable of. A chimp would never plan to pull another's nails out. The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

Certainly, if you look at human behavior around the world, you have to admit that we can be very aggressive.

Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings.

Thousands of people who say they "love" animals sit down once or twice a day to enjoy the flesh of creatures who have been utterly deprived of everything that could make their lives worth living and who endured the awful suffering and the terror of the abattoirs...

We have so far to go to realize our human potential for compassion, altruism, and love.
