Upon the purple tree-tops far away, and on the green height near at hand up which the shades were slowly creeping, there was an equal hush. Between the real landscape and its shadow in the water, there was no division; both were so untroubled and clear, and, while so fraught with solemn mystery of life and death, so hopefully reassuring to the gazer's soothed heart, because so tenderly and mercifully beautiful.
If purpose, then, is inherent in art, so is it in Nature also. The best illustration is the case of a man being his own physician, for Nature is like that - agent and patient at once.
But the moon came slowly up in all her gentle glory, and the stars looked out, and through the small compass of the grated window, as through the narrow crevice of one good deed in a murky life of guilt, the face of Heaven shone bright and merciful. He raised his head; gazed upward at the quiet sky, which seemed to smile upon the earth in sadness, as if the night, more thoughtful than the day, looked down in sorrow on the sufferings and evil deeds of men; and felt its peace sink deep into his heart.
Man carries the world in his head, the whole astronomy and chemistry suspended in a thought. Because the history of nature is charactered in his brain, therefore he is the prophet and discoverer of her secrets. Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified.
The night crept on apace, the moon went down, the stars grew pale and dim, and morning, cold as they, slowly approached. Then, from behind a distant hill, the noble sun rose up, driving the mists in phantom shapes before it, and clearing the earth of their ghostly forms till darkness came again.
Let us guard against saying that there are laws in nature. There are merely necessities: there is no one who commands, no one whoobeys, no one who transgresses. Once you understand that there are no purposes, then you also understand that nothing is accidental: for it is only in a world of purposes that the word "accident" makes sense.
