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. NOVELTY AND CURIOSITY. Curiosity is the most superficial of all the affections; it changes its object perpetually, it has an appetite which is very sharp, but very easily satisfied; and it has always an appearance of giddiness, restlessness, and anxiety. Curiosity, from its nature, is a very active principle; it quickly runs over the greatest part of its objects, and soon exhausts the variety which is commonly to be met with in nature; the same things make frequent returns, and they return with less and less of any agreeable effect. In short, the occurrences of life, by the time we come to know it a little, would be incapable of affecting the mind with any other sensations than those of loathing and weariness, if many things were not adapted to affect the mind by means of other powers besides novelty in them, and of other passions besides curiosity in ourselves. PLEASURES OF ANALOGY. The mind of man has naturally a far greater alacrity and satisfaction in tracing resemblances than in searching for differences: because by making resemblances we produce NEW IMAGES; we unite, we create, we enlarge our stock; but in making distinctions we offer no food at all to the imagination; the task itself is more severe and irksome, and what pleasure we derive from it is something of a negative and indirect nature. AMBITION. God has planted in man a sense of ambition, and a satisfaction arising from the contemplation of his excelling his fellows in something deemed valuable amongst them. It is this passion that drives men to all the ways we see in use of signalizing themselves, and that tends to make whatever excites in a man the idea of this distinction so very pleasant. It has been so strong as to make very miserable men take comfort, that they were supreme in misery; and certain it is, that, where we cannot distinguish ourselves by something excellent, we begin to take a complacency in some singular infirmities, follies, or defects of one kind or other. It is on this principle that flattery is so prevalent; for flattery is no more than what raises in a man's mind an idea of a preference which he has not. EXTENSIONS OF SYMPATHY.
