All the objects which are exhibited to our view by Nature, upon close examination will be found to have their blemishes and defects. The most beautiful forms have something about them like weakness, minuteness, or imperfection. But it is not every eye that perceives these blemishes. It must be an eye long used to the contemplation and comparison of these forms; and which, by a long habit of observing what any set of objects of the same kind have in common, has acquired the power of discerning what each wants in particular. This long, laborious comparison should be the first study of the Painter who aims at the great style. By this means he acquires a just idea of beautiful forms; he corrects Nature by herself, her imperfect state by her more perfect. His eye being enabled to distinguish the accidental deficiencies, excrescences, and deformities of things, from their general figures, he makes out an abstract idea of their forms more perfect than any one original; and what may seem a paradox, he learns to design naturally by drawing his figures unlike to any one object. This idea of the perfect state of Nature, which the Artist calls the Ideal beauty, is the great leading principle by which works of genius are conducted. By this Phidias acquired his fame. He wrought upon a sober principle what has so much excited the enthusiasm of the world; and by this method you, who have courage to tread the same path, may acquire equal reputation. This is the idea which has acquired, and which seems to have a right to, the epithet of _divine_; as it may be said to preside, like a supreme judge, over all the productions of Nature, appearing to be possessed of the will and intention of the Creator, as far as they regard the external form of living beings. When a man once possesses this idea in its perfection, there is no danger but that he will be sufficiently warmed by it himself, and be able to warm and ravish every one else. Thus it is from a reiterated experience, and a close comparison of the objects in Nature, that an artist becomes possessed of the idea of that central form, if I may so express it, from which every deviation is deformity. But the investigation of this form, I grant, is painful, and I know but of one method of shortening the road; this is, by a careful study of the works of the ancient sculptors; who, being indefatigable in the school of Nature, have left models of that perfect form behind them, which an artist would prefer as supremely beautiful, who had spent his whole life in that single contemplation. But if industry carried them thus far, may not you also hope for the same reward from the same labour? We have the same school opened to us that was opened to them; for Nature denies her instructions to none who desire to become her pupils.
