History does not relate for the sake of relating; it does not paint for the sake of painting; it relates and paints the past that it may be the living lesson of the future. It proposes to instruct new generations by the experience of those who have gone before them, by exhibiting to them a faithful picture of great and important events, with their causes and their effects, with general designs and particular passions, with the faults, virtues, and crimes that are found mingled together in human things. It teaches the excellence of prudence, courage, and great thoughts profoundly meditated, constantly pursued, and executed with moderation and force. It shows the vanity of immoderate pretensions, the power of wisdom and virtue, the impotence of folly and crime. Thucydides, Polybius, and Tacitus undertake any thing else than procuring new emotions for an idle curiosity or a worn-out imagination; they doubtless desire to interest and attract, but more to instruct; they are the avowed masters of statesmen and the preceptors of mankind.
The sole object of art is the beautiful. Art abandons itself as soon as it shuns this. It is often constrained to make concessions to circumstances, to external conditions that are imposed upon it; but it must always retain a just liberty. Architecture and the art of gardening are the least free of arts; they are subjected to unavoidable obstacles; it belongs to the genius of the artist to govern these obstacles, and even to draw from them happy effects, as the poet turns the slavery of metre and rhyme into a source of unexpected beauties. Extreme liberty may carry art to a caprice which degrades it, as chains too heavy crush it. It is the death of architecture to subject it to convenience, to comfort. Is the architect obliged to subordinate general effect and the proportions of the edifice to such or such a particular end that is prescribed to him? He takes refuge in details, in pediments, in friezes, in all the parts that have not utility for a special object, and in them he becomes a true artist. Sculpture and painting, especially music and poetry, are freer than architecture and the art of gardening. One can also shackle them, but they disengage themselves more easily.
Similar by their common end, all the arts differ by the particular effects which they produce, and by the processes which they employ. They gain nothing by exchanging their means and confounding the limits that separate them. I bow before the authority of antiquity; but, perhaps, through habit and a remnant of prejudice, I have some difficulty in representing to myself with pleasure statues composed of several metals, especially painted statues.[123] Without pretending that sculpture has not to a certain point its color, that of perfectly pure matter, that especially which the hand of time impresses upon it, in spite of all the seductions of a contemporaneous[124] artist of great talent, I have little taste, I confess, for that artifice that is forced to give to marble the morbidezza of painting. Sculpture is an austere muse; it has its graces, but they are those of no other art. Flesh-color must remain a stranger to it: there would nothing more remain to communicate to it but the movement of poetry and the indefiniteness of music! And what will music gain by aiming at the picturesque, when its proper domain is the pathetic? Give to the most learned symphonist a storm to render. Nothing is easier to imitate than the whistling of the winds and the noise of thunder. But by what combinations of harmony will he exhibit to the eyes the glare of the lightning rending all of a sudden the veil of the night, and what is most fearful in the tempest, the movement of the waves that now ascend like a mountain, now descend and seem to precipitate themselves into bottomless abysses? If the auditor is not informed of the subject, he will never suspect it, and I defy him to distinguish a tempest from a battle. In spite of science and genius, sounds cannot paint forms. Music, when well guided, will guard itself from contending against the impossible; it will not undertake to express the tumult and strife of the waves and other similar phenomena; it will do more: with sounds it will fill the soul with the sentiments that succeed each other in us during the different scenes of the tempest. Haydn will thus become[125] the rival, even the vanquisher of the painter, because it has been given to music to move and agitate the soul more profoundly than painting.
Since the Laocoon of Lessing, it is no longer permitted to repeat, without great reserve, the famous axiom,—Ut pictura poesis; or, at least, it is very certain that painting cannot do every thing that poetry can do. Everybody admires the picture of Rumor, drawn by Virgil; but let a painter try to realize this symbolic figure; let him represent to us a huge monster with a hundred eyes, a hundred mouths, and a hundred ears, whose feet touch the earth, whose head is lost in the clouds, and such a figure will become very ridiculous.
So the arts have a common end, and entirely different means. Hence the general rules common to all, and particular rules for each. I have neither time nor space to enter into details on this point. I limit myself to repeating, that the great law which governs all others, is expression. Every work of art that does not express an idea signifies nothing; in addressing itself to such or such a sense, it must penetrate to the mind, to the soul, and bear thither a thought, a sentiment capable of touching or elevating it. From this fundamental rule all the others are derived; for example, that which is continually and justly recommended,—composition. To this is particularly applied the precept of unity and variety. But, in saying this, we have said nothing so long as we have not determined the nature of the unity of which we would speak. True unity, is unity of expression, and variety is made only to spread over the entire work the idea or the single sentiment that it should express. It is useless to remark, that between composition thus defined, and what is often called composition, as the symmetry and arrangement of parts according to artificial rules, there is an abyss. True composition is nothing else than the most powerful means of expression.
Expression not only furnishes the general rules of art, it also gives the principle that allows of their classification.
In fact, every classification, supposes a principle that serves as a common measure.
Such a principle has been sought in pleasure, and the first of arts has seemed that which gives the most vivid joys. But we have proved that the object of art is not pleasure:—the more or less of pleasure that an art procures cannot, then, be the true measure of its value.
This measure is nothing else than expression. Expression being the supreme end, the art that most nearly approaches it is the first of all.
All true arts are expressive, but they are diversely so. Take music; it is without contradiction the most penetrating, the profoundest, the most intimate art. There is physically and morally between a sound and the soul a marvellous relation. It seems as though the soul were an echo in which the sound takes a new power. Extraordinary things are recounted of the ancient music. And it must not be believed that the greatness of effect supposes here very complicated means. No, the less noise music makes, the more it touches. Give some notes to Pergolese, give him especially some pure and sweet voices, and he returns a celestial charm, bears you away into infinite spaces, plunges you into ineffable reveries. The peculiar power of music is to open to the imagination a limitless career, to lend itself with astonishing facility to all the moods of each one, to arouse or calm, with the sounds of the simplest melody, our accustomed sentiments, our favorite affections. In this respect music is an art without a rival:—however, it is not the first of arts.
