Hope is not wishful thinking. It's not a temperament we're born with. It is a stance toward life that we can choose...not not. The real question for me, though, is whether m hope is effective, whether it produces or is just where I hide to ease my own pain.

With an eco-mind, we get ready for surprises, for we realize it's just not possible to know what's possible.

Every aspect of our lives is, in a sense, a vote for the kind of world we want to live in.

Freedom is not the capacity to do whatever we please; freedom is the capacity to make intelligent choices.

I think of Wangari Mathai in Kenya. If she started out saying she wanted to plant 20 million trees, she would have been laughed at. In fact, the foresters and the government did laugh at her. They said, "Villagers? Un-schooled villagers? Planting trees? No, no, no, it takes foresters." So she planted trees anyway.

My children threw me a life line: "Return to your roots - food - and rewrite your first book, Diet for a Small Planet." I learned that if I could just show up, in this case, if I could just get myself out of bed, get to the computer in my tiny office at MIT, and start writing, help would start arriving.
