“As I drift back into sleep, I can't help thinking that it's a wonderful thing to be right about the world. To weigh the evidence, always incomplete, and correctly intuit the whole, to see the world in a grain of sand, to recognize its beauty, its simplicity, its truth. It's as close as we get to God in this life, and reside in the glow of such brief flashes of understanding, fully awake, sometimes for two or three seconds, at peace with our existence. And then back to sleep we go.”
