Guido exercised a powerful influence over his immediate successors. Guercino felt it when he painted that soulless picture of Abraham and Hagar, in the Brera—the picture which excited Byron's admiration, which has been praised for its accurate delineation of a teardrop, and which, when all is reckoned, has just nothing of emotion in it but a frigid inhumanity. He competed with Guido in the fresco of the Lodovisi Aurora, a substantial work certainly, yet one that lacks the saving qualities of the Rospigliosi ceiling—grace and geniality of fancy.

In the history of criticism there are few things more perplexing than the vicissitudes of taste and celebrity, whereby the idols of past generations crumble suddenly to dust, while the despised and rejected are lifted to pinnacles of glory. Successive waves of aesthetical preference, following one upon the other with curious rapidity, sweep ancient fortresses of fame from their venerable basements, and raise upon the crests of wordy foam some delicate seashell that erewhile lay embedded in oblivious sand. During the last half-century, taste has been more capricious, revolutionary, and apparently anarchical than at any previous epoch. The unity of orthodox opinion has broken up. Critics have sought to display originality by depreciating names famous in former ages, and by exalting minor stars to the rank of luminaries of the first magnitude. A man, yet in middle life, can remember with what reverence engravings after Raphael, the Caracci, and Poussin were treated in his boyhood; how Fra Angelico and Perugino ruled at a somewhat later period; how one set of eloquent writers discovered Blake, another Botticelli, and a third Carpaccio; how Signorelli and Bellini and Mantegna received tardy recognition; and now, of late years, how Tiepolo has bidden fair to obtain the European grido. He will also bear in mind that the conditions of his own development—studies in the Elgin marbles, the application of photography to works of art, the publications of the Arundel Society, and that genius of new culture in the air which is more potent than all teaching, rendered for himself each oracular utterance interesting but comparatively unimportant—as it were but talk about truths evident to sight.

Meanwhile, amid this gabble of 'sects and schisms,' this disputation which makes a simple mind take refuge in the epigram attributed to Swift on Handel and Bononcini,[234] criticism and popular intelligence have been unanimous upon two points, first, in manifesting a general dislike for Italian art after the date of Raphael's third manner, and a particular dislike for the Bolognese painters; secondly, in an earnest effort to discriminate and exhibit what is sincere and beautiful in works to which our forefathers were unintelligibly irresponsive. A wholesome reaction, in one word, has taken place against academical dogmatism; and the study of art has been based upon appreciably better historical and aesthetical principles.

The seeming confusion of the last half-century ought not, therefore, to shake our confidence in the possibility of arriving at stable laws of taste. Radical revolutions, however salutary, cannot be effected without some injustice to ideals of the past and without some ill-grounded enthusiasm for the ideals of the moment. Nor can so wide a region as that of modern European art be explored except by divers pioneers, each biassed by personal predilections and peculiar sensibilities, each liable to changes of opinion under the excitement of discovery, each followed by a coterie sworn to support their master's ipse dixit.

The chief thing is to obtain a clear conception of the mental atmosphere in which sound criticism has to live and move and have its being. 'The form of this world passes; and I would fain occupy myself only with that which constitutes abiding relations.' So said Goethe; and these words have much the same effect as that admonition of his 'to live with steady purpose in the Whole, the Good, the Beautiful.' The true critic must divert his mind from what is transient and ephemeral, must fasten upon abiding relations, bleibende Verhältnisse. He notes that one age is classical, another romantic; that this swears by Giotto, that by the Caracci. Meanwhile, he resolves to maintain that classics and romantics, the Caracci and Giotto, are alike only worthy of regard in so far as they exemplify the qualities which bring art into the sphere of abiding relations. One writer is eloquent for Fra Angelico, another for Rubens; the one has personal sympathy for the Fiesolan monk, the other for the Flemish courtier. Our true critic renounces idiosyncratic whims and partialities, striving to enter with firm purpose into the understanding of universal goodness and beauty. In so far as he finds truth in Angelico and Rubens, will he be appreciative of both.

Aristotle laid it down as an axiom that the ultimate verdict in matters of taste is 'what the man of enlightened intelligence would decide.' The critic becomes a man of enlightened intelligence, a [Greek: phronimos], by following the line of Goethe's precepts. In working out self-culture, he will derive assistance by the way from the commanding philosophical conception of our century. All things with which we are acquainted are in evolutionary process. Everything belonging to human nature is in a state of organic transition—passing through necessary phases of birth, growth, decline, and death. Art, in any one of its specific manifestations—Italian painting for example—avoids this law of organic evolution, arrests development at the fairest season of growth, averts the decadence which ends in death, no more than does an oak. The oak, starting from an acorn, nourished by earth, air, light, and water, offers indeed a simpler problem than so complex an organism as Italian painting, developed under conditions of manifold diversity. Yet the dominant law controls both equally.

It is not, however, in evolutions that we must seek the abiding relations spoken of by Goethe. The evolutionary conception does not supply those to students of art, though it unfolds a law which is permanent and of universal application in the world at large. It forces us to dwell on necessary conditions of mutability and transformation. It leads the critic to comprehend the whole, and encourages the habit of scientific tolerance. We are saved by it from uselessly fretting ourselves because of the ungodly and the inevitable; from mourning over the decline of Gothic architecture into Perpendicular aridity and flamboyant feebleness, over the passage of the scepter from Sophocles to Euripides or from Tasso to Marino, over the chaos of Mannerism, Eclecticism and Naturalism into which Italian painting plunged from the height of its maturity. This toleration and acceptance of unavoidable change need not imply want of discriminative perception. We can apply the evolutionary canon in all strictness without ignoring that adult manhood is preferable to senile decrepitude, that Pheidias surpasses the sculptors of Antinous, that one Madonna of Gian Bellini is worth all the pictures of the younger Palma, and that Dossi's portrait of the Ferrarese jester is better worth having than the whole of Annibale Caracci's Galleria Farnesina.[235] It will even lead us to select for models those works which bear the mark of adolescence or vigorous maturity, as supplying more fruitful sources for our own artistic education.

Nevertheless, not in evolution, but in man's soul, his intellectual and moral nature, must be sought those abiding relations which constitute sound art, and are the test of right aesthetic judgment. These are such as truth, simplicity, sobriety, love, grace, patience, modesty, thoughtfulness, repose, health, vigor, brain-stuff, dignity of imagination, lucidity of vision, purity, and depth of feeling. Wherever the critic finds these—whether it be in Giotto at the dawn or in Guido at the evensong of Italian painting, in Homer or Theocritus at the two extremes of Greek poetry—he will recognize the work as ranking with those things from which the soul draws nourishment. At the same time, he may not neglect the claims of craftsmanship. Each art has its own vehicle of expression, and exacts some innate capacity for the use of that vehicle from the artist. Therefore the critic must be also sufficiently versed in technicalities to give them their due value. It can, however, be laid down, as a general truth, that while immature or awkward workmanship is compatible with aesthetic excellence, technical dexterity, however skillfully applied, has never done anything for a soulless painter.

Criticism, furthermore, implies judgment; and that judgment must be adjusted to the special nature of the thing criticised. Art is different from ethics, from the physical world, from sensuality, however refined. It will not, therefore, in the long run do for the critic of an art to apply the same rules as the moralist, the naturalist, or the hedonist. It will not do for him to be contented with edification, or differentiation of species, or demonstrable delightfulness as the test-stone of artistic excellence. All art is a presentation of the inner human being, his thought and feeling, through the medium of beautiful symbols in form, color, and sound. Our verdict must therefore be determined by the amount of thought, the amount of feeling, proper to noble humanity, which we find adequately expressed in beautiful aesthetic symbols. And the man who shall pronounce this verdict is, now as in the days of Aristotle, the man of enlightened intelligence, sound in his own nature and open to ideas. Even his verdict will not be final; for no one is wholly free from partialities due to the age in which he lives, and to his special temperament. Still, a consensus of such verdicts eventually forms that voice of the people which, according to an old proverb, is the voice of God. Slowly, and after many successive siftings, the cumulative votes of the phronimoi decide. Insurgents against their judgment, in the case of acknowledged masters like Pheidias, Michelangelo, Shakespeare, are doomed to final defeat, because this judgment is really based upon abiding relations between art and human nature.

Our hope with regard to the unity of taste in the future then is, that, all sentimental or academical seekings after the ideal having been abandoned, momentary theories founded upon idiosyncratic or temporary partialities exploded, and nothing accepted but what is solid and positive, the scientific spirit shall make men progressively more and more conscious of those bleibende Verhältnisse, more and more capable of living in the whole; also that, in proportion as we gain a firmer hold upon our own place in the world, we shall come to comprehend with more instinctive certitude what is simple, natural, and honest, welcoming with gladness all artistic products that exhibit these qualities. The perception of the enlightened man will then be the taste of a healthy person who has made himself acquainted with the laws of evolution in art and in society, and is able to test the excellence of work in any stage, from immaturity to decadence, by discerning what there is of truth, sincerity, and natural vigor in it.
