Every time we walk along a beach some ancient urge disturbs us so that we find ourselves shedding shoes and garments or scavenging among seaweed and whitened timbers like the homesick refugees of a long war ... Mostly the animals understand their roles, but man, by comparison, seems troubled by a message that, it is often said, he cannot quite remember or has gotten wrong ... Bereft of instinct, he must search continually for meanings ... Man was a reader before he became a writer, a reader of what Coleridge once called the mighty alphabet of the universe.
