TASTE AND SMELL.
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.
