Something in me was always watching life from the outside, permanently obsessed with the notion of belonging vs. not-belonging [to a group]. It did not make for a happy childhood, but it was excellent training for a writer.

On the day I swore to uphold the Hippocratic oath, the small hairs on the back of my neck stood up as I waited for lightning to strike. Who was I, vowing calmly among all these necktied young men to steal life out of nature's jaws, every old time we got half a chance and a paycheck?... I could not accept the contract: that every child born human upon this earth comes with a guarantee of perfect health and old age clutched in its small fist.

Wake up now, look alive, for here is a day off work just to praise Creation: the turkey, the squash, and the corn, these things that ate and drank sunshine, grass, mud, and rain, and then in the shortening days laid down their lives for our welfare and onward resolve. There's the miracle for you, the absolute sacrifice that still holds back seed: a germ of promise to do the whole thing again, another time. . . Thanksgiving is Creation's birthday party. Praise harvest, a pause and sigh on the breath of immortality.

What a writer can do, what a fiction writer or a poet or an essay writer can do is re-engage people with their own humanity.

I know I'm a rare person, a trained scientist who writes fiction, because so few contemporary novelists engage with science.

It's very important to distinguish between innocence and naivete. The innocent do not deserve to be the victims of violence. But only the naive refuse to think about the origins of violence and to pursue the possibility that the genesis of that hatred could be addressed.

When I look out the window, I exhale a prayer of thanks for the color green, for my children's safety, for the simple acts of faith like planting a garden that helped see us through another spring, another summer. And I inhale some kind of promise to protect my kids' hopes and good intentions we began with in this country. Freedom of speech, the protection of diversity - these are the most important ingredients of American civil life and my own survival. If I ever took them for granted, I don't know.
