So I spoke, as the words came to me, while we were still driving down the dark valley, in deeper shadows, under higher bluffs, looking out on a levelled world westward, stretching off with low, white, wreathing mists and moonlit distances of plains beyond the further bunk. We turned a great shoulder of the hills, and the moon shone out bright and clear, riding in heaven; and the southward reach unlocked, and gave itself for miles to our eyes. At the instant, while the ponies came back upon their haunches at the drop of the long descent ahead, we both cried out, "the Looking-glass!" There it was, about a mile away before and below us, as plain as a pikestaff,--a silvery reach, like a long narrow lake, smooth as the floor of cloud seen from above among mountains, silent, motionless,--for all the world like an immense, spectral looking-glass, set there in the half-darkened waste. It was evidently what gave the name to the creek, and I have since noticed the same name elsewhere in the Western country, and I suppose the phenomenon is not uncommon. For an hour or more it remained; we never seemed to get nearer to it; it was an eerie thing--the earth-light of the moon on that side,--I saw it all the time.
"The difference you spoke of," I began, with my eyes upon that spectral pool, "is only that change which belongs to life, dissolving like illusion, but not itself illusion. I am not aware of any break; it is the old life in a higher form with clearer selfhood. Life, in the soul especially, seems less a state of being than a thing of transformation, whose successive shapes we wear; and so far as that change is self-determined," I continued, making almost an effort to think, so weird was that scene before us, "the soul proceeds by foreknowledge of itself in the ideal, and wills the change by ideal living, which is not a conflict with the actual but a process out of it, conditioned in almost a Darwinian way on that brain-futuring which entered into the struggle for animal existence even with such enormous modifying power. In our old days, under the sway of new scientific knowledge, we instinctively saw man in the perspective of nature, and then man seemed almost an after-thought of nature; but having been produced, late in her material history, and gifted with foresight that distinguished him from all else in her scheme, his own evolution gathered thereby that speed which is so perplexing a contrast to the inconceivable slowness of the orbing of stars and the building of continents. He has used his powers of prescience for his own ends; but, fanciful as the thought is, might it happen that through his control of elemental forces and his acquaintance with infinite space, he should reach the point of applying prescience in nature's own material frame, and wield the world for the better accomplishment of her apparent ends,--that, though unimaginable now, would constitute the true polarity to her blind and half-chaotic motions,--chaotic in intelligence, I mean, and to the moral reason. Unreal as such a thought is, a glimpse of some such feeling toward nature is discernible in the work of some impressionist landscape painters, who present colour and atmosphere and space without human intention, as a kind of artistry of science, having the same sort of elemental substance and interest that scientific truth has as an object of knowledge,--a curious form of the beauty of truth."
