This is a beauty dependent on reverie, fancy, and objectified emotion. The promiscuous natural landscape cannot be enjoyed in any other way. It has no real unity, and therefore requires to have some form or other supplied by the fancy; which can be the more readily done, in that the possible forms are many, and the constant changes in the object offer varying suggestions to the eye. In fact, psychologically speaking, there is no such thing as a landscape; what we call such is an infinity of different scraps and glimpses given in succession. Even a painted landscape, although it tends to select and emphasize some parts of the field, is composed by adding together a multitude of views. When this painting is observed in its turn, it is surveyed as a real landscape would be, and apperceived partially and piecemeal; although, of course, it offers much less wealth of material than its living original, and is therefore vastly inferior. Only the extreme of what is called impressionism tries to give upon canvas one absolute momentary view; the result is that when the beholder has himself actually been struck by that aspect, the picture has an extraordinary force and emotional value -- like the vivid power of recalling the past possessed by smells. But, on the other hand, such a work is empty and trivial in the extreme; it is the photograph of a detached impression, not followed, as it would be in nature, by many variations of itself. An object so unusual is often unrecognizable, if the vision thus unnaturally isolated has never happened to come vividly into our own experience. The opposite school -- what might be called _discursive_ landscape painting -- collects so many glimpses and gives so fully the sum of our positive observations of a particular scene, that its work is sure to be perfectly intelligible and plain. If it seems unreal and uninteresting, that is because it is formless, like the collective object it represents, while it lacks that sensuous intensity and movement which might have made the reality stimulating.
