Hansen, Sunset, 1996
Let your walks now be a little more adventurous; ascend the hills. If, about the last of October, you ascend any hill in the outskirts of our town, and probably of yours, and look over the forest, you may see——well, what I have endeavored to describe. All this you surely will see, and much more, if you are prepared to see it,—if you look for it. Otherwise, regular and universal as this phenomenon is, whether you stand on the hill-top or in the hollow, you will think for threescore years and ten that all the wood is, at this season, sear and brown. Objects are concealed from our view, not so much because they are out of the course of our visual ray as because we do not bring our minds and eyes to bear on them; for there is no power to see in the eye itself, any more than in any other jelly. We do not realize how far and widely, or how near and narrowly, we are to look. The greater part of the phenomena of Nature are for this reason concealed from us all our lives. The gardener sees only the gardener’s garden. Here, too, as in political economy, the supply answers to the demand. Nature does not cast pearls before swine. There is just as much beauty visible to us in the landscape as we are prepared to appreciate,—not a grain more. The actual objects which one man will see from a particular hill-top are just as different from those which another will see as the beholders are different.
Henry David Thoreau, from "Autumn Tints"
