This succession, however, is not governed by unavoidable necessity. The God of nature offers it to us, in order to advance our happiness; and it is sufficient, that he hath enabled us to complete the succession. Nor has he made our task disagreeable or difficult. On the contrary, the transition is sweet and easy, from corporeal pleasures to the more refined pleasures of sense; and not less so, from these to the exalted pleasures of morality and religion. We stand therefore engaged in honour, as well as interest, to second the purposes of nature, by cultivating the pleasures of the eye and ear, those especially that require extraordinary culture[3], such as are inspired by poetry, painting, sculpture, music, gardening, and architecture. This chiefly is the duty of the opulent, who have leisure to improve their minds and their feelings. The fine arts are contrived to give pleasure to the eye and the ear, disregarding the inferior senses. A taste for these arts is a plant that grows naturally in many soils; but, without culture, scarce to perfection in any soil. It is susceptible of much refinement; and is, by proper care, greatly improved. In this respect, a taste in the fine arts goes hand in hand with the moral sense, to which indeed it is nearly allied. Both of them discover what is right and what is wrong. Fashion, temper, and education, have an influence upon both, to vitiate them, or to preserve them pure and untainted. Neither of them are arbitrary or local. They are rooted in human nature, and are governed by principles common to all men. The principles of morality belong not to the present undertaking. But as to the principles of the fine arts, they are evolved, by studying the sensitive part of human nature, and by learning what objects are naturally agreeable, and what are naturally disagreeable. The man who aspires to be a critic in these arts, must pierce still deeper. He must clearly perceive what objects are lofty, what low, what are proper or improper, what are manly, and what are mean or trivial. Hence a foundation for judging of taste, and for reasoning upon it. Where it is conformable to principles, we can pronounce with certainty, that it is correct; otherwise, that it is incorrect, and perhaps whimsical. Thus the fine arts, like morals, become a rational science; and, like morals, may be cultivated to a high degree of refinement.
