Perhaps we too seldom reflect how much the life of Nature is one with the life of man, how unimportant or indeed merely seeming, the difference between them. Who can set a seed in the ground, and watch it put up a green shoot, and blossom and fructify and wither and pass, without reflecting, not as imagery but as fact, that he has come into existence, run his course, and is going out of existence again, by precisely the same process? With so serious a correspondence between their vital experience, the fact of one being a tree and the other a man seems of comparatively small importance. The life process has but used different material for its expression. And as man and Nature are so like in such primal conditions, is it not to be supposed that they are alike too in other and subtler ways, and that, at all events, as it thus clearly appears that man is as much a natural growth as an apple-tree, alike dependent on sun and rain, may not, or rather must not, the thoughts that come to him strangely out of earth and sky, the sap-like stirrings of his spirit, the sudden inner music that streams through him before the beauty of the world, be no less authentically the working of Nature within him than his more obviously physical processes, and, say, a belief in God be as inevitable a blossom of the human tree as apple-blossom of the apple?
If this oracular office of Nature be indeed a truth, our contemplation of her beauty and marvel is seen to be a method of illumination, and her varied spectacle actually a sacred book in picture-writing, a revelation through the eye of the soul of the stupendous purport of the universe. The sun and the moon are the torches by which we study its splendid pages, turning diurnally for our perusal, and in star and flower alike dwells the lore which we cannot formulate into thought, but can only come indescribably to know by loving the pictures. “The meaning of all things that are” is there, if we can only find it. It flames in the sunset, or flits by us in the twilight moth, thunders or moans or whispers in the sea, unveils its bosom in the moonrise, affirms itself in mountain-range and rooted oak, sings to itself in solitary places, dreams in still waters, nods and beckons amid sunny foliage, and laughs its great green laugh in the wide sincerity of the grass.
