As we are proud of riches in ourselves, so to satisfy our vanity we desire that everyone, who has any connection with us, should likewise be posses of them, and are ashamed of any one, that is mean or poor, among our friends and relations. For this reason we remove the poor as far from us as possible; and as we cannot prevent poverty in some distant collaterals, and our forefathers are taken to be our nearest relations; upon this account every one affects to be of a good family, and to be descended from a long succession of rich and honorable ancestors.
Those, who boast of the antiquity of their families, are glad when they can join this circumstance, that their ancestors for many generations have been uninterrupted proprietors of the same portion of land, and that their family has never changed its possessions, or been transplanted into any other county or province. It is an additional subject of vanity, when they can boast, that these possessions have been transmitted thro' a descent composed entirely of males, and that the honor, and fortune have never past thro' any female.
When any one boasts of the antiquity of his family, the subjects of his vanity are not merely the extent of time and number of ancestors, but also their riches and credit, which are supposed to reflect a luster on himself on account of his relation to them. He first considers these objects; is affected by them in an agreeable manner; and then returning back to himself, thro' the relation of parent and child, is elevated with the passion of pride, by means of the double relation, of impressions and ideas. Since therefore the passion depends on these relations, whatever strengthens any of the relations must also increase the passion, and whatever weakens the relations must diminish the passion. Now it is certain the identity of the possession strengthens the relation of ideas arising from blood and kindred, and conveys the fancy with greater facility from one generation to another, from the remote ancestors to their posterity, who are both their heirs and their descendants. By this facility the impression is transmitted more entire, and excites a greater degree of pride and vanity.
Everything belonging to a vain man is the best that is anywhere to be found. His houses, equipage, furniture, cloths, horses, excel all others in his conceit; and it is easy to observe, that from the least advantage in any of these, he draws a new subject of pride and vanity. His wine, if you'll believe him, has a finer flavor than any other; his cookery is more exquisite; his table more orderly; his servants more expert; the air, in which he lives, more healthful; the soil he cultivates more fertile; his fruits ripen earlier and to greater perfection: Such a thing is remarkable for its novelty; such another for its antiquity: This is the workmanship of a famous artist; that belonged once to such a prince or great man: All objects, in a word, that are useful, beautiful or surprising, or are related to such, may, by means of property, give rise to this passion. These agree in giving pleasure, and agree in nothing else. This alone is common to them; and therefore must be the quality that produces the passion, which is their common effect.
When riches produce any pride or vanity in their possessors, as they never fail so do, it is only by means of a double relation of impressions and ideas. The very essence of riches consists in the power of procuring the pleasures and conveniences of life. The very essence of this consists in the probability of its exercise, and in its causing us to anticipate, by a true or false reasoning, the real existence of the pleasure. This anticipation of pleasure is, in itself, a very considerable pleasure; and as its cause is some possession or property, which we enjoy, and which is thereby related to us, we here dearly see all the parts of the foregoing system most exactly and distinctly drawn out before us. For the same reason, that riches cause pleasure and pride, and poverty excites uneasiness and humility, power must produce the former emotions, and slavery the latter. Power or an authority over others makes us capable of satisfying all our desires; as slavery, by subjecting us to the will of others, exposes us to a thousand wants, and mortifications.
