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.

It is a funny thing what the brain will do with memories and how it will treasure them and finally bring them into odd juxtapositions with other things, as though it wanted to make a design, or get some meaning out of them, whether you want it or not, or even see it.

I once saw, on a flower pot in my own living room, the efforts of a field mouse to build a remembered field. I have lived to see this episode repeated in a thousand guises, and since I have spent a large portion of my life in the shade of a nonexistent tree I think I am entitled to speak for the field mouse.

Since the first human eye saw a leaf in Devonian sandstone and a puzzled finger reached to touch it, sadness has lain over the heart of man. By this tenuous thread of living protoplasm, stretching backward into time, we are linked forever to lost beaches whose sands have long since hardened into stone. The stars that caught our blind amphibian stare have shifted far or vanished in their courses, but still that naked, glistening thread winds onward. No one knows the secret of its beginning or its end. Its forms are phantoms. The thread alone is real; the thread is life.

It is a commonplace of all religious thought, even the most primitive, that the man seeking visions and insight must go apart from his fellows and love for a time in the wilderness.

Certainly science has moved forward. But when science progresses, it often opens vaster mysteries to our gaze. Moreover, science frequently discovers that it must abandon or modify what it once believed. Sometimes it ends by accepting what it has previously scorned.

It has been asserted that we are destined to know the dark beyond the stars before we comprehend the nature of our own journey.
