It is my design to consider beauty as distinguished from the sublime; and, in the course of the inquiry, to examine how far it is consistent with it. But previous to this, we must take a short review of the opinions already entertained of this quality; which I think are hardly to be reduced to any fixed principles; because men are used to talk of beauty in a figurative manner, that is to say, in a manner extremely uncertain, and indeterminate. By beauty, I mean that quality, or those qualities in bodies, by which they cause love, or some passion similar to it. I confine this definition to the merely sensible qualities of things, for the sake of preserving the utmost simplicity in a subject, which must always distract us whenever we take in those various causes of sympathy which attach us to any persons or things from secondary considerations, and not from the direct force which they have merely on being viewed. I likewise distinguish love, (by which I mean that satisfaction which arises to the mind upon contemplating anything beautiful, of whatsoever nature it may be,) from desire or lust; which is an energy of the mind, that hurries us on to the possession of certain objects, that do not affect us as they are beautiful, but by means altogether different. We shall have a strong desire for a woman of no remarkable beauty; whilst the greatest beauty in men, or in other animals, though it causes love, yet excites nothing at all of desire. Which shows that beauty, and the passion caused by beauty, which I call love, is different from desire, though desire may sometimes operate along with it; but it is to this latter that we must attribute those violent and tempestuous passions, and the consequent emotions of the body which attend what is called love in some of its ordinary acceptations, and not to the effects of beauty merely as it is such.
