in external objects, is requisite to attach us to them. Doth not this mechanism, in the first place, greatly promote industry, by prompting a desire to possess things that are beautiful? Doth it not further join with utility, in prompting us to embellish our houses and enrich our fields? These however are but slight effects, compared with the connections which are formed among individuals in society by means of this singular mechanism. The qualifications of the head and heart, are undoubtedly the most solid and most permanent foundations of such connections. But as external beauty lies more in view, and is more obvious to the bulk of mankind than the qualities now mentioned, the sense of beauty possesses the more universal influence in forming these connections. At any rate, it concurs in an eminent degree with mental qualifications, to produce social intercourse, mutual good-will, and consequently mutual aid and support, which are the life of society. It must not however be overlooked, that this sense doth not tend to advance the interests of society, but when in a due mean with respect to strength. Love in particular arising from a sense of beauty, loses, when excessive, its sociable character[53]. The appetite for gratification, prevailing over affection for the beloved object, is ungovernable; and tends violently to its end, regardless of the misery that must follow. Love in this state is no longer a sweet agreeable passion. It becomes painful like hunger or thirst; and produceth no happiness but in the instant of fruition. This discovery suggests a most important lesson, that moderation in our desires and appetites, which fits us for doing our duty, contributes at the same time the most to happiness. Even social passions, when moderate, are more pleasant than when they swell beyond proper bounds. CHAP. IV. Grandeur and Sublimity. Nature hath not more remarkably distinguished us from the other animals by an erect posture, than by a capacious and aspiring mind, inclining us to every thing great and elevated. The ocean, the sky, or any large object, seizes the attention, and makes a strong impression[54]. Robes of state are made large and full to draw respect. We admire elephants and whales for their magnitude, notwithstanding their unwieldiness. The elevation of an object affects us not less than its magnitude. A high place is chosen for the statue of a deity or hero. A tree growing upon the brink of a precipice viewed from the plain below, affords by that circumstance an additional pleasure. A throne is erected for the chief magistrate, and a chair with a high seat for the president of a court. In some objects, greatness and elevation concur to make a complicated impression. The Alps and the pike of Teneriff are proper examples; with the following difference, that in the former greatness seems to prevail, elevation in the latter.
