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 frequently the tragedy of the great artist for example Vincent Van Gogh, as it is of the great scientist, that he frightens the ordinary man. If he is more than a popular story-teller it may take humanity a generation to absorb and grow accustomed to the new geography with which the scientist or artist presents us. Even then, perhaps only the more imaginative and literate may accept him. Subconsciously the genius is feared as an image breaker; frequently he does not accept the opinions of the mass, or man's opinion of himself.

The creature called man has a strange history. He is not of one piece, nor was he born of a single moment in time. His elementary substance is stardust almost as old as the universe.

Great minds have always seen it. That is why man has survived his journey this long. When we fail to wish any longer to be otherwise than what we are, we will have ceased to evolve. Evolution has to be lived forward. I say this as one who has stood above the bones of much that has vanished, and at midnight has examined his own face.

The creative element in the mind of man . . . emerges in as mysterious a fashion as those elementary particles which leap into momentary existence in great cyclotrons, only to vanish again like infinitesimal ghosts.

[On common water.] Its substance reaches everywhere; it touches the past and prepares the future; it moves under the poles and wanders thinly in the heights of air. It can assume forms of exquisite perfection in a snowflake, or strip the living to a single shining bone cast up by the sea.

Animals are molded by natural forces they do not comprehend. To their minds there is no past and no future. There is only the everlasting present of a single generation, its trails in the forest, its hidden pathways in the the air and in the sea. There is nothing in the Universe more alone than Man. He has entered into the strange world of history.
