The general merit of these Discourses is so well established that it would be needless to enlarge on it here. The graces of the composition are such, that scholars have been led to suspect that it was the style of Burke (the first prose-writer of our time) carefully subdued, and softened down to perfection: and the taste and knowledge of the subject displayed in them are so great, that this work has been, by common consent, considered as a text-book on the subject of art, in our English school of painting, ever since its publication. Highly elegant and valuable as Sir Joshua’s opinions are, yet they are liable (so it appears to us) to various objections; and it becomes more important to state these objections, because, as it generally happens, the most questionable of his precepts are those which have been the most eagerly adopted, and carried into practice with the greatest success. The errors, if they are such, which we shall attempt to point out, are not casual, but systematic. There is a finespun metaphysical theory, either not very clearly understood, or not very correctly expressed, pervading Sir Joshua’s reasoning; and which appears to have led him in several of the most important points to conclusions, either false or only true in part.[16] The rules thus laid down, as general and comprehensive maxims, are in fact founded on a set of half principles, which are true only as far as they imply a negation of the opposite errors, but contain in themselves the germ of other errors just as fatal: which, if strictly and literally understood, cannot be defended, and which by being taken in an equivocal sense, of course leave the student as much to seek as ever. The English school of painting is universally reproached by foreigners with the slovenly and unfinished state in which they send their productions into the world, with their ignorance of academic rules and neglect of the subordinate details; in other words, with aiming at _effect_ only in all their works of art: and though it is by no means necessary that we should adopt the defects of the French and German painters, yet we might learn from them to correct our own. There was no occasion to encourage our constitutional indolence and impatience by positive rules, or to incorporate our vicious habits into a system. Or if our defects were to be retained, at least they ought to have been tolerated only for the sake of certain collateral and characteristic excellencies out of which they might be thought to spring. Thus a certain degree of precision or regularity might be sacrificed rather than impair that boldness, vigour, and originality of conception, in which the strength of the national genius might be supposed to lie. But the method of instruction pursued in the Discourses seems calculated for neither of these objects. Without endeavouring to overcome our habitual defects, which might be corrected by proper care and study, it damps our zeal, ardour, and enthusiasm.
