" He meant the Grand Canyon was only a mood of nature, a bold promise, a beautiful record. He meant that mountains had sifted away in its dust, yet the canyon was young. Man was nothing, so let him be humble. This cataclysm of the earth, this playground of a river was not inscrutable; it was only inevitable—as inevitable as nature herself. Millions of years in the bygone ages it had lain serene under a half moon; it would bask silent under a rayless sun, in the onward edge of time.
It taught simplicity, serenity, peace. The eye that saw only the strife, the war, the decay, the ruin, or only the glory and the tragedy, saw not all the truth. It spoke simply, though its words were grand: "My spirit is the Spirit of Time, of Eternity, of God. Man is little, vain, vaunting. Listen. To-morrow he shall be gone. Peace! Peace! "
