Fear doesn't have to stop us.

I think back to when I was growing up in Fort Worth, Texas, in the 1950s, during the [John] McCarthy era, with two parents who founded a Unitarian Church. We lived in a little frame house, and my bedroom was just down the hall from the kitchen. My favorite memories of childhood are of the smell of coffee wafting into my bedroom as my parents and their friends talked about the big, important things - about racism and about how to move our country to live its values.

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.

I think we are at a new evolutionary stage. We evolved in tight-knit tribes in which we faced death if we didn't have the support of the rest of the tribe.

I read a book in the late 1990s called The Anatomy of Human Destructiveness, by Erich Fromm, and it had a profound impact on me. Fromm takes Descartes' statement, "I think, therefore I am" and changes it to "I effect, therefore I am."

For me, just showing up for the traveling and writing gave me the power to overcome my fear of fear.

Fear doesn't necessarily mean that we have to stop. It doesn't mean that we are failures. It doesn't mean that we are cowards.
