It is but fair to avow that this enquiry into the progress of the arts has not been entered on for the sole purpose of ascertaining, as far as we were able, the causes of the surpassing excellence to which they were carried in Greece, without at the same time intimating, with due deference to superior judgments and to superior authority, the efficacy of the same causes, at all times and in all countries, in improving and exalting them. As human nature is the same at all periods, though diversified in its exterior shew by the various customs, modes, and manners, that variously prevail, it cannot be seriously doubted but that those principles, which have been found by experience in one country to powerfully sway its conduct, and to incite its efforts in the Arts to their noblest productions, would be equally efficient and equally successful elsewhere, were they fairly applied, and as vigorously exerted. We have no satisfactory reason for believing that either the mental or corporeal powers of man have degenerated in the succession of ages: and we well know that, by the benefits of experience and invention, considerable aids have been added to both, to methodize their motions and to facilitate their operations. Our profounder and better-studied knowledge of Metaphysics, our improved skill in Natural Philosophy and Mechanics, and our more accurate acquaintance with the principles of colours, with their combinations and their shades, all confessedly tend to these points. Should then the same liberal public encouragement be displayed, by those possessed of the power of displaying it, as dignified the best days of Greece; should the same labour, the same pains, the same study, the same industry, be used by modern artists as distinguished their truly illustrious predecessors; we might not vainly hope to see the arts carried to still greater perfection than they have ever yet attained; we might expect to behold their deficiencies supplied, their utilities increased, their energies enlarged, and their beauties augmented.
