The object therefore of this mixed passion, which we call love, is the BEAUTY of the SEX. Men are carried to the sex in general, as it is the sex, and by the common law of nature; but they are attached to particulars by personal BEAUTY. I call beauty a social quality; for where women and men, and not only they, but when other animals give us a sense of joy and pleasure in beholding them (and there are many that do so), they inspire us with sentiments of tenderness and affection towards their persons; we like to have them near us, and we enter willingly into a kind of relation with them, unless we should have strong reasons to the contrary.
