The first idea that occurs in the consideration of what is fixed in art, or in taste, is that presiding principle of which I have so frequently spoken in former discourses,—the general idea of nature. The beginning, the middle, and the end of everything that is valuable in taste, is comprised in the knowledge of what is truly nature; for whatever notions are not conformable to those of nature, or universal opinion, must be considered as more or less capricious.

My notion of nature comprehends not only the forms which nature produces, but also the nature and internal fabric and organisation, as I may call it, of the human mind and imagination. The terms beauty, or nature, which are general ideas, are but different modes of expressing the same thing, whether we apply these terms to statues, poetry, or pictures. Deformity is not nature, but an accidental deviation from her accustomed practice. This general idea, therefore, ought to be called Nature; and nothing else, correctly speaking, has a right to that name. But we are sure so far from speaking, in common conversation, with any such accuracy, that, on the contrary, when we criticise Rembrandt and other Dutch painters, who introduced into their historical pictures exact representations of individual objects with all their imperfections, we say—Though it is not in a good taste, yet it is nature.

This misapplication of terms must be very often perplexing to the young student. Is not art, he may say, an imitation of nature? Must he not, therefore, who imitates her with the greatest fidelity be the best artist? By this mode of reasoning Rembrandt has a higher place than Raffaelle. But a very little reflection will serve to show us that these particularities cannot be nature; for how can that be the nature of man, in which no two individuals are the same?

It plainly appears, that as a work is conducted under the influence of general ideas, or partial, it is principally to be considered as the effect of a good or a bad taste.

As beauty, therefore, does not consist in taking what lies immediately before you, so neither, in our pursuit of taste, are those opinions which we first received and adopted the best choice, or the most natural to the mind and imagination. In the infancy of our knowledge we seize with greediness the good that is within our reach; it is by after-consideration, and in consequence of discipline, that we refuse the present for a greater good at a distance. The nobility or elevation of all arts, like the excellency of virtue itself, consists in adopting this enlarged and comprehensive idea; and all criticism built upon the more confined view of what is natural may properly be called shallow criticism, rather than false: its defect is, that the truth is not sufficiently extensive.

It has sometimes happened that some of the greatest men in our art have been betrayed into errors by this confined mode of reasoning. Poussin, who upon the whole may be produced as an artist strictly attentive to the most enlarged and extensive ideas of nature, from not having settled principles on this point, has, in one instance at least, I think, deserted truth for prejudice. He is said to have vindicated the conduct of Julio Romano for his inattention to the masses of light and shade, or grouping the figures in The Battle of Constantine, as if designedly neglected, the better to correspond with the hurry and confusion of a battle. Poussin's own conduct in many of his pictures makes us more easily give credit to this report. That it was too much his own practice, The Sacrifice to Silenus, and The Triumph of Bacchus and Ariadne, may be produced as instances; but this principle is still more apparent, and may be said to be even more ostentatiously displayed in his Perseus and Medusa's Head.

This is undoubtedly a subject of great bustle and tumult, and that the first effect of the picture may correspond to the subject, every principle of composition is violated; there is no principal figure, no principal light, no groups; everything is dispersed, and in such a state of confusion, that the eye finds no repose anywhere. In consequence of the forbidding appearance, I remember turning from it with disgust, and should not have looked a second time, if I had not been called back to a closer inspection. I then indeed found, what we may expect always to find in the works of Poussin, correct drawing, forcible expression, and just character; in short, all the excellencies which so much distinguish the works of this learned painter.

This conduct of Poussin I hold to be entirely improper to imitate. A picture should please at first sight, and appear to invite the spectator's attention: if, on the contrary, the general effect offends the eye, a second view is not always sought, whatever more substantial and intrinsic merit it may possess.

Perhaps no apology ought to be received for offences committed against the vehicle (whether it be the organ of seeing or of hearing) by which our pleasures are conveyed to the mind. We must take care that the eye be not perplexed and distracted by a confusion of equal parts, or equal lights, or offended by an unharmonious mixture of colours, as we should guard against offending the ear by unharmonious sounds. We may venture to be more confident of the truth of this observation, since we find that Shakespeare, on a parallel occasion, has made Hamlet recommend to the players a precept of the same kind—never to offend the ear by harsh sounds: In the very torrent, tempest, and whirlwind of your passion, says he, you must acquire and beget a temperance that may give it smoothness. And yet, at the same time, he very justly observes, The end of playing, both at the first, and now, was, and is, to hold, as 'twere, the mirror up to nature. No one can deny that violent passions will naturally emit harsh and disagreeable tones; yet this great poet and critic thought that this imitation of nature would cost too much, if purchased at the expense of disagreeable sensations, or, as he expresses it, of splitting the ear. The poet and actor, as well as the painter of genius, who is well acquainted with all the variety and sources of pleasure in the mind and imagination, has little regard or attention to common nature, or creeping after common-sense. By overleaping those narrow bounds, he more effectually seizes the whole mind, and more powerfully accomplishes his purpose. This success is ignorantly imagined to proceed from inattention to all rules, and a defiance of reason and judgment; whereas it is in truth acting according to the best rules and the justest reason.

He who thinks nature, in the narrow sense of the word, is alone to be followed, will produce but a scanty entertainment for the imagination; everything is to be done with which it is natural for the mind to be pleased, whether it proceeds from simplicity or variety, uniformity or irregularity; whether the scenes are familiar or exotic; rude and wild, or enriched and cultivated; for it is natural for the mind to be pleased with all these in their turn. In short, whatever pleases has in it what is analogous to the mind, and is, therefore, in the highest and best sense of the word, natural.
