The wealth, the aggrandizement, and power of nations, are commonly the effects of virtue; the loss of these advantages is often a consequence of vice. Were we to suppose men to have succeeded in the discovery and application of every art by which states are preserved and governed; to have attained, by efforts of wisdom and magnanimity, the admired establishments and advantages of a civilized and flourishing people; the subsequent part of their history, containing, according to vulgar apprehension, a full display of those fruits in maturity, of which they had till then carried only the blossom, and the first formation, should, still more than the former, merit our attention, and excite our admiration. The event, however, has not corresponded to this expectation. The virtues of men have shone most during their struggles, not after the attainment of their ends. Those ends themselves, though attained by virtue, are frequently the causes of corruption and vice. Mankind, in aspiring to national felicity, have substituted arts which increase their riches, instead of those which improve their nature. They have entertained admiration of themselves, under the titles of _civilized_ and of _polished_, where they should have been affected with shame; and even where they have, for a while, acted on maxims tending to raise, to invigorate, and to preserve the national character, they have, sooner or later, been diverted from their object, and fallen a prey to misfortune, or to the neglects which prosperity itself had encouraged. War, which furnishes mankind with a principal occupation of their restless spirit, serves, by the variety of its events, to diversify their fortunes. While it opens to one tribe or society, the way to eminence, and leads to dominion, it brings another to subjection, and closes the scene of their national efforts. The celebrated rivalship of Carthage and Rome was, in both parties, the natural exercise of an ambitious spirit, impatient of opposition, or even of equality. The conduct and the fortune of leaders held the balance for some time in suspense; but to which ever side it had inclined, a great nation was to fall; a seat of empire, and of policy, was to be removed from its place; and it was then to be determined, whether the Syriac or the Latin should contain the erudition that was, in future ages, to occupy the studies of the learned.
