The Astonishing Thing

Viewed from the distance of the moon, the astonishing thing about the earth, catching the breath, is that it is alive.

Lewis Thomas wrote this in the title essay of The Lives of a Cell, published in 1974, not long after the first photographs of the whole earth from space had reached the public. He was a physician and researcher, trained to look for what's wrong, trained in the clinical habits of diagnosis and explanation. But looking at that blue and white planet against the dead surface of the moon, he doesn't diagnose anything, he just stops and notices the plain, staggering fact that it is alive at all. That kind of astonishment, at something so basic we usually forget to see it, is where gratitude actually starts.
