I get goose-bumps when you talk about Diane Wilson. Who knows where she found that courage? When she was a child, she would crawl under the bed when a stranger came to the house. But in 1989, she found out that her county in south Texas was ranked worst in the country for toxic waste. She wondered if the effluent, dumped into the waters where she and her family had shrimped for generations, might be responsible for the dwindling fish populations. And she suspected that her son's autism might be related to the pollution.

Fear doesn't have to stop us.

Even the fear of death is nothing compared to the fear of not having lived authentically and fully.

I had no identity [when I was 27] - I was terrified that somebody would ask me what I was doing, and I would have no answer.

In the late 1960s, there were alarming predictions that worldwide famine was around the corner. I wondered if humans had already lost the race, overrun the Earth's capacity. I let one question lead to the next, and unearthed information that would forever change my life: Not only is there enough food in the world to feed every man, woman, and child on Earth, there is enough to make us all chubby.

I never like to use those terms [like pessimistic].

What we see today is a world movement represented by the World Social Forum, involving all sorts of interactions across cultures, not to create some new "ism," but to learn as we walk and to create more democratic forms of social organization that re-embed economic life in community.
