Between the scale of atoms and the scale of stars, between the time of mayflies and the time of mountains, we exist as proteins lit up with purpose, matter yearning for meaning on a planet capable of trees and tenderness, a world on which every living thing abides by the same dumb resilience through which we rose from the oceans to compose the Benedictus and to build the bomb. All of our models and our maps. all of our poems and our love songs, all the conjectures chalked on the blackboard of the mind in theorems and scriptures, spring from the same elemental restlessness to locate ourselves in the cosmos of being, to know reality and to know ourselves.
