On the Sublime and Beautiful/Part III/Chapter 26
THIS general agreement of the senses is yet more evident on minutely considering those of taste and smell. We metaphorically apply the idea of sweetness to sights and sounds; but as the qualities of bodies, by which they are fitted to excite either pleasure or pain in these senses, are not so obvious as they are in the others, we shall refer an explanation of their analogy, which is a very close one, to that part, wherein we come to consider the common efficient cause of beauty, as it regards all the senses. I do not think anything better fitted to establish a clear and settled idea of visual beauty than this way of examining the similar pleasures of other senses; for one part is sometimes clear in one of the senses, that is more obscure in another; and where there is a clear concurrence of all, we may with more certainty speak of any one of them. By this means, they bear witness to each other; nature is, as it were, scrutinized; and we report nothing of her but what we receive from her own information.
