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.

Each one of us matters, has a role to play, and makes a difference. Each one of us must take responsibility for our own lives, and above all, show respect and love for living things around us, especially each other.

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.

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

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.

From my perspective, I absolutely believe in a greater spiritual power, far greater than I am, from which I have derived strength in moments of sadness or fear. That's what I believe, and it was very, very strong in the forest.
