Every man contains within himself a ghost continent.

Nothing grows among its pinnacles; there is no shade except under great toadstools of sandstone whose bases have been eaten to the shape of wine glasses by the wind. Everything is flaking, cracking, disintegrating, wearing away in the long, inperceptible weather of time. The ash of ancient volcanic outbursts still sterilizes its soil, and its colors in that waste are the colors that flame in the lonely sunsets on dead planets.

It has been said that great art is the night thought of man. It may emerge without warning from the soundless depths of the unconscious, just as supernovas may blaze up suddenly in the farther reaches of void space.

We think we learn from teachers, and we sometimes do. But the teachers are not always to be found in school or in great laboratories. Sometimes what we learn depends upon our own powers of insight.

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.

A man who has once looked with the archaeological eye will never see quite normally. He will be wounded by what other men call trifles. It is possible to refine the sense of time until an old shoe in the bunch grass or a pile of nineteenth century beer bottles in an abandoned mining town tolls in one's head like a hall clock.

The secret, if one may paraphrase a savage vocabulary, lies in the egg of night.
