• When we try to pick out anything by itself, we find it hitched to everything else in the universe. One fancies a heart like our own must be beating in every crystal and cell, and we feel like stopping to speak to the plants and animals as friendly fellow-mountaineers. Nature as a poet, an enthusiastic workingman, becomes more and more visible the farther and higher we go.
