Here's what I mean by the miracle of language. When you're falling into a good book, exactly as you might fall into a dream, a little conduit opens, a passageway between a reader's heart and a writer's, a connection that transcends the barriers of continents and generations and even death ...

We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical swarm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us.
