Within every cell there are eloquently evolved molecular machines, nucleic acids, enzymes, the cell architecture; every cell is a triumph of natural selection and we are made of trillions of cells. We are each of us a multitude. Within us is a little universe.

In every culture, the sky and the religious impulse are intertwined. I lie back in an open field and the sky surrounds me. I’m overpowered by its scale. It’s so vast and so far away that my own insignificance becomes palpable. But I don’t feel rejected by the sky. I’m a part of it - tiny, to be sure, but everything is tiny compared to that overwhelming immensity. And when I concentrate on the stars, the planets, and their motions, I have an irresistible sense of machinery, clockwork, elegant precision working on a scale that, however lofty our aspirations, dwarfs and humbles us.
