Animals have personalities and minds and emotions.

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.

If harsher laws are put in place, less will dare to break them.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

If you look into their [chimpanzees] eyes, you know you're looking into a thinking mind. They teach us that we are not the only beings with personalities, minds capable of rational thought, altruism and a sense of humor. That leads to new respect for other animals, respect for the environment and respect for all life.

Every stage of my life set the scene for the next, and at each point all I had to do was say "yes" and not think too much about the consequences.

Lasting change is a series of compromises.
