On the Sublime and Beautiful/Part III/Chapter 24
THE FOREGOING description of beauty, so far as it is taken in by the eye, may be greatly illustrated by describing the nature of objects, which produce a similar effect through the touch. This I call the beautiful in Feeling. It corresponds wonderfully with what causes the same species of pleasure to the sight. There is a chain in all our sensations; they are all but different sorts of feelings calculated to be affected by various sorts of objects, but all to be affected after the same manner. All bodies that are pleasant to the touch, are so by the slightness of the resistance they make. Resistance is either to motion along the surface, or to the pressure of the parts on one another: if the former be slight, we call the body smooth; if the latter, soft. The chief pleasure we receive by feeling, is in the one or the other of these qualities; and if there be a combination of both, our pleasure is greatly increased. This is so plain, that it is rather more fit to illustrate other things, than to be illustrated itself by an example. The next source of pleasure in this sense, as in every other, is the continually presenting somewhat new; and we find that bodies which continually vary their surface, are much the most pleasant or beautiful to the feeling, as any one that pleases may experience. The third property in such objects is, that though the surface continually varies its direction, it never varies it suddenly. The application of anything sudden, even though the impression itself have little or nothing of violence, is disagreeable. The quick application of a finger a little warmer or colder than usual, without notice, makes us start; a slight tap on the shoulder, not expected, has the same effect. Hence it is that angular bodies, bodies that suddenly vary the direction of the outline, afford so little pleasure to the feeling. Every such change is a sort of climbing or falling in miniature; so that squares, triangles, and other angular figures, are neither beautiful to the sight nor feeling. Whoever compares his state of mind, on feeling soft, smooth, variegated, unangular bodies, with that in which he finds himself, on the view of a beautiful object, will perceive a very striking analogy in the effects of both; and which may go a good way towards discovering their common cause. Feeling and sight, in this respect, differ in but a few points. The touch takes in the pleasure of softness, which is not primarily an object of sight; the sight, on the other hand, comprehends colour, which can hardly be made perceptible to the touch; the touch, again, has the advantage in a new idea of pleasure resulting from a moderate degree of warmth; but the eye triumphs in the infinite extent and multiplicity of its objects. But there is such a similitude in the pleasures of these senses, that I am apt to fancy, if it were possible that one might discern colour by feeling, (as it is said some blind men have done,) that the same colours, and the same disposition of colouring, which are found beautiful to the sight, would be found likewise most grateful to the touch. But, setting aside conjectures, let us pass to the other sense; of Hearing.
