the images which light affords, cannot be in itself a pleasant thing; and those sudden crashes with which the thunder shakes the atmosphere, those sudden flashes when the lightning rends the cloud—all is contrary to one of the essential conditions of the beautiful, which carries with it nothing abrupt, nothing violent. And moreover this phenomenon, if we consider only our senses, is rather painful than agreeable, for the nerves of our sight and those of our hearing are each in their turn painfully strained, then not less violently relaxed, by the alternations of light and darkness, of the explosion of the thunder, and silence. And in spite of all these causes of displeasure, a storm is an attractive phenomenon for whomsoever is not afraid of it. Another example. In the midst of a green and smiling plain there rises a naked and barren hillock, which hides from the sight a part of the view. Each one would wish that this hillock were removed which disfigures the beauty of all the landscape. Well, let us imagine this hillock rising, rising still, without indeed changing at all its shape, and preserving, although on a greater scale, the same proportions between its width and height. To begin with, our impression of displeasure will but increase with the hillock itself, which will the more strike the sight, and which will be the more repulsive. But continue; raise it up twice as high as a tower, and insensibly the displeasure will efface itself to make way for quite another feeling. The hill has at last become a mountain, so high a mountain that it is quite impossible for our eyes to take it in at one look. There is an object more precocious than all this smiling plain which surrounds it, and the impression that it makes on us is of such a nature that we should regret to exchange it for any other impression, however beautiful it might be. Now, suppose this mountain to be leaning, and of such an inclination that we could expect it every minute to crash down, the previous impression will be complicated with another impression: terror will be joined to it: the object itself will be but still more attractive. But suppose it were possible to prop up this leaning mountain with another mountain, the terror would disappear, and with it a good part of the pleasure we experienced. Suppose that there were beside this mountain four or five other mountains, of which each one was a fourth or a fifth part lower than the one which came immediately after; the first impression with which the height of one mountain inspired us will be notably weakened. Something somewhat analogous would take place if the mountain itself were cut into ten or twelve terraces, uniformly diminishing; or again if it were artificially decorated with plantations. We have at first subjected one mountain to no other operation than that of increasing its size, leaving it otherwise just as it was, and without altering its form; and this simple
