Man is as much attached to nature as a tree, and though he walks freely on two legs and is not rooted in the soil, he is by no means a self-sufficient, self-moving, and self-directing entity. For his life he depends absolutely on the same factors as the tree, the worm, and the fly, on the universal powers of nature, life, God, or whatever it may be. From some mysterious source life flows through him unceasingly; it does not just go in at birth and come out at death—he is the channel for an ever moving stream, a stream that carries the blood through his veins, that moves his lungs and brings him air to breathe, that raises his food from the earth and bears the light of the sun to his face. If we look into a single cell of his body we find the universe, for sun, moon, and stars are ceaselessly maintaining it; we find it again if we plumb into the depths of his mind, for there are all the archaic urges of primeval life, both human and animal, and could we look deeper we might find kinship with the plants and rocks.
