Note 54 — Chapter IV

"Conquests, by uniting many nations under one sovereign, have formed great and powerful empires, out of the ruins of many petty states. In these great empires, men began insensibly to form clearer views of politics, juster and more salutary notions of government. Experience taught them to avoid the errors which had occasioned the ruin of the nations whom they had subdued, and put them upon taking measures to prevent surprises, invasions, and the like misfortunes. With these views they fortified cities, secured such passes as might have admitted an enemy into their country, and kept a certain number of troops constantly on foot. By these precautions, several States rendered themselves formidable to their neighbors, and none durst lightly attack powers which were every way so respectable. The interior parts of such mighty monarchies were no longer exposed to ravages and devastations. War was driven far from the centre, and only infected the frontiers. The inhabitants of the country, and of the cities, began to breathe in safety. The calamities which conquests and revolutions had occasioned, disappeared; but the blessings which had grown out of them, remained. Ingenious and active spirits, encouraged by the repose which they enjoyed, devoted themselves to study. It was in the bosom of great empires the arts were invented, and the sciences had their birth."—Op. cit., vol. i. Book 5, p. 326.—H. [54]
