there have been too many events in my life, and in the lives of my friends, which have defied any kind of scientific explanation. Science does not have appropriate tools for the dissection of the spirit.

Language allows us to talk about the past and plan the future. We can teach children about things that are not present. And above all, we can bring people with different backgrounds and different knowledge together to discuss our problems. This actually gives me hope. I still think we are smart enough to not destroy planet Earth, our only home.

Chimps are far too much human to be my favorite animal.

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

I was even accused of teaching the chimps how to fish for termites which I mean that would have been such a brilliant coup.

Change happens by listening and then starting a dialogue with the people who are doing something you don't believe is right.

I don't have any idea of who or what God is. But I do believe in some great spiritual power. I feel it particularly when I’m out in nature. It’s just something that's bigger and stronger than what I am or what anybody is. I feel it. And it's enough for me.
