Physics is prayer in an iconic universe.20 Thus the universe is a kind of text, which inspires contemplation of the deep patterns built in by the craftsman.21 All of these orchestrated motions exist because they constitute the best possible way to make manifest the perfection of eternity.22 And when we grasp this point, we have come to the heart of the “iconic” nature of the model Lewis so admired. It is a difficult concept—time’s imitation of eternity—but Lewis thought it was fundamental to the understanding of the medieval world.
