“All things are engaged in writing their history. The planet, the pebble, goes attended by its shadow. The rolling rock leaves its scratches on the mountain; the river, its channel in the soil; the animal, its bones in the stratum; the fern and leaf their modest epitaph in the coal. The falling drop makes its sculpture in the sand or the stone. Not a foot steps into the snow, or along the ground, but prints in characters more or less lasting, a map of its march .... The air is full of sounds; the sky, of tokens; the ground is all memoranda and signatures; and every object covered over with hints, which speak to the intelligent.”
—Ralph Waldo Emerson
