From the political state of mankind in the days of their ancient splendor it was natural that those arts which depend on the imagination, such as Architecture, Statuary, Painting, Eloquence and Poetry, should claim the highest rank in the estimation of a people. In several, perhaps all of these, the ancients remain unrivalled. But these are not the arts which tend the most to the general improvement of society. A man in those days would have rendered more service to the world by ascertaining the true figure and movements of the earth, than by originating a heaven and filling it with all the gods of Homer; and had the expenses of the Egyptian pyramids been employed in furnishing ships of discovery and sending them out of the Mediterranean, the nations called civilized would not have been afterwards overrun by Barbarians.
But the sciences of Geography, Navigation and Commerce, with their consequent improvements in Natural Philosophy and Humanity, could not, from the nature of things at that time, become objects of great encouragement or enterprise. Talent was therefore confined to the cultivation of arts more striking to the senses. As these arts were adapted to gratify the vanity of princes, to help carry on the sacred frauds of priests, to fire the ambition of heroes, or to gain causes in popular assemblies, they were brought to a degree of perfection which prevented their being relished or understood by barbarous neighbors.
The improvements of the world therefore, whether in literature, sciences or arts, descended with the line of conquest from one nation to another, till the whole were concentred in the Roman empire. Their tendency there was to inspire a contempt for nations less civilized, and to teach the Romans to consider all mankind as the proper objects of their military despotism. These circumstances prepared, thro a course of ages, and finally opened a scene of wretchedness at which the human mind has been taught to shudder. But some such convulsion seemed necessary to reduce the nations to a position capable of commencing regular improvements. And, however novel the sentiment may appear, I will venture to say that, as to the prospect of universal civilization, mankind were in a better situation in the time of Charlemagne than they were in the days of Augustus.
