We are made by the laws of physics, working through four billion years of evolution. We have a brief window of life through which to see the universe, and understand how we came to be in it. The truth may not always be comforting in the face of suffering, but it has a majesty of its own. That’s what I tell people when they ask me: “Why do you bother to get up in the mornings?”
