The Real Cause of Beauty

HAVING endeavoured to show what beauty is not, it remains that we should examine, at least with equal attention, in what it really consists. Beauty is a thing much too affecting not to depend upon some positive qualities. And, since it is no creature of our reason, since it strikes us without any reference to use, and even where no use at all can be discerned, since the order and method of nature is generally very different from our measures and proportions, we must conclude that beauty is, for the greater part, some quality in bodies acting mechanically upon the human mind by the intervention of the senses. We ought therefore to consider attentively in what manner those sensible qualities are disposed, in such things as by experience we find beautiful, or which excite in us the passion of love, or some correspondent affection.
