I"ve never been more aware of the limitations of language than when I try to describe beauty. Language can create its own loveliness, of course, but it cannot deliver to us the radiance we apprehend in the world, any more than a photograph can capture the stunning swiftness of a hawk or the withering power of a supernova. Eva"s wedding album holds only a faint glimmer of the wedding itself. All that pictures or words can do is gesture beyond themselves toward the fleeting glory that stirs our hearts. So I keep gesturing. " All nature is meant to make us think of paradise," Thomas Merton observed. Because the Creation puts on a nonstop show, beauty is free and inexhaustible, but we need training in order to perceive more than the most obvious kinds. Even 15 billion years or so after the Big Bang, echoes of that event still linger in the form of background radiation, only a few degrees above absolute zero. Just so, I believe, the experience of beauty is an echo of the order and power that permeate the universe. To measure background radiation, we need subtle instruments; to measure beauty, we need alert intelligence and our five keen senses.
