The problem of art is to reach the soul through the body. Art offers to the senses forms, colors, sounds, words, so arranged that they excite in the soul, concealed behind the senses, the inexpressible emotion of beauty.
Expression is addressed to the soul as form is addressed to the senses. Form is the obstacle of expression, and, at the same time, is its imperative, necessary, only means. By working upon form, by bending it to its service, by dint of care, patience, and genius, art succeeds in converting an obstacle into a means.
By their object, all arts are equal; all are arts only because they express the invisible. It cannot be too often repeated, that expression is the supreme law of art. The thing to express is always the same,—it is the idea, the spirit, the soul, the invisible, the infinite. But, as the question is concerning the expression of this one and the same thing, by addressing ourselves to the senses which are diverse, the difference of the senses divides art into different arts.
We have seen, that, of the five senses which have been given to man,[120] three—taste, smell, and touch—are incapable of producing in us the sentiment of beauty. Joined to the other two, they may contribute to the understanding of this sentiment; but alone and by themselves they cannot produce it. Taste judges of the agreeable, not of the beautiful. No sense is less allied to the soul and more in the service of the body; it flatters, it serves the grossest of all masters, the stomach. If smell sometimes seems to participate in the sentiment of the beautiful, it is because the odor is exhaled from an object that is already beautiful, that is beautiful for some other reason. Thus the rose is beautiful for its graceful form, for the varied splendor of its colors; its odor is agreeable, it is not beautiful. Finally, it is not touch alone that judges of the regularity of forms, but touch enlightened by sight.
There remain two senses to which all the world concedes the privilege of exciting in us the idea and the sentiment of the beautiful. They seem to be more particularly in the service of the soul. The sensations which they give have something purer, more intellectual. They are less indispensable for the material preservation of the individual. They contribute to the embellishment rather than to the sustaining of life. They procure us pleasures in which our personality seems less interested and more self-forgetful. To these two senses, then, art should be addressed, is addressed, in fact, in order to reach the soul. Hence the division of arts into two great classes,—arts addressed to hearing, arts addressed to sight; on the one hand, music and poetry; on the other, painting, with engraving, sculpture, architecture, gardening.
It will, perhaps, seem strange that we rank among the arts neither eloquence, nor history, nor philosophy.
The arts are called the fine arts, because their sole object is to produce the disinterested emotion of beauty, without regard to the utility either of the spectator or the artist. They are also called the liberal arts, because they are the arts of free men and not of slaves, which affranchise the soul, charm and ennoble existence; hence the sense and origin of those expressions of antiquity, artes liberales, artes ingenuæ. There are arts without nobility, whose end is practical and material utility; they are called trades, such as that of the stove-maker and the mason. True art may be joined to them, may even shine in them, but only in the accessories and the details.
Eloquence, history, philosophy, are certainly high employments of intelligence; they have their dignity, their eminence, which nothing surpasses, but rigorously speaking, they are not arts.
Eloquence does not propose to itself to produce in the soul of the auditors the disinterested sentiment of beauty. It may also produce this effect, but without having sought it. Its direct end, which it can subordinate to no other, is to convince, to persuade. Eloquence has a client which before all it must save or make triumph. It matters little, whether this client be a man, a people, or an idea. Fortunate is the orator if he elicits the expression: That is beautiful! for it is a noble homage rendered to his talent; unfortunate is he if he does not elicit this, for he has missed his end. The two great types of political and religious eloquence, Demosthenes in antiquity, Bossuet among the moderns, think only of the interest of the cause confided to their genius, the sacred cause of country and that of religion; whilst at bottom Phidias and Raphael work to make beautiful things. Let us hasten to say, what the names of Demosthenes and Bossuet command us to say, that true eloquence, very different from that of rhetoric, disdains certain means of success; it asks no more than to please, but without any sacrifice unworthy of it; every foreign ornament degrades it. Its proper character is simplicity, earnestness—I do not mean affected earnestness, a designed and artful gravity, the worst of all deceptions—I mean true earnestness, that springs from sincere and profound conviction. This is what Socrates understood by true eloquence.[121]
As much must be said of history and philosophy. The philosopher speaks and writes. Can he, then, like the orator, find accents which make truth enter the soul, colors and forms that make it shine forth evident and manifest to the eyes of intelligence? It would be betraying his cause to neglect the means that can serve it; but the profoundest art is here only a means, the aim of philosophy is elsewhere; whence it follows that philosophy is not an art. Without doubt, Plato is a great artist; he is the peer of Sophocles and Phidias, as Pascal is sometimes the rival of Demosthenes and Bossuet;[122] but both would have blushed if they had discovered at the bottom of their soul another design, another aim than the service of truth and virtue.
