Thus having attempted to investigate the progress of the arts, and to what was owing that supreme excellence which they formerly attained, we seem to have reasonable grounds to conclude that it flowed from such natural and moral causes as, at all times and in all cases, are known powerfully to affect the feelings and to actuate the conduct of man. No whimsical refinements, no marvellous mysteries, no imaginary and fantastic theories have been had recourse to: but lighted on our way by the irradiating torch of authentic history, and unseduced by the false glare of lying legends, we have not dared so much to affirm what, in certain situations, our fellow-creatures MUST do, as to detail with some care what in fact they DID do. If what we have here advanced has not the attraction of novelty to allure, it is hoped that it is not deficient in the recommendation of truth to convince. It has not been thought necessary formally to refute the sentiments of those profound Philosophers, who have sagaciously discovered the causes of the inferiority of the arts in some countries and of their superiority in others, and consequently the perfection to which they arrived in Greece, in the power of the solar beams in certain latitudes, in the influences of the atmosphere, and in those of terrestrial and celestial vapours: for if the causes here assigned appear fully adequate to the end produced, as we conceive they do, it must be idle to shew the inutility of others, gratuitously brought forth from the inexhaustible storehouse of fancy, and supported by any thing rather than solid reasoning. It must be allowed that they very roundly assert, but as fallaciously argue, whenever they deign to argue on this subject: for mere assertions, positive, pompous, presuming, but assertions still, are the commonest weapons of their warfare. And, possibly, it would neither be reputable to contest the specious subtilty of the sophisms of even such sages, nor honourable to conquer the powerless imbecility of their assertions.
