I believe that accurate knowledge is very, very important, but find that out in free time. Don't let it take over every hour of the day. Perhaps most important, talk about it.

The only possible way to get somebody to change is to reach into their hearts.

It was because the chimps are so eye-catching, so like us and teach us so much that my work was recognised worldwide.

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.

They used to ask: "How will this decision that we make today affect our people in the future?" Now we make decisions based on: "How does it affect me, now? How does it affect the next shareholders meeting, three months ahead? How does it affect my next political campaign?"

Primates are very territorial. It is in their nature to protect their food resources as well as their females and young.

Chimps taught us we're not separated from the animal kingdom, we're a part of it.
