"The conception of every work of art carries within it its own rule and method, which must be found out before it can be achieved." "Chaque oeuvre à faire a sa poétique en soi, qu'il faut trouver," said Flaubert. Truth in a work of art is sincerity. That a man says what he really means--shows us what he really thinks to be beautiful--is all that reason bids us ask for. No science or painstaking can make up for his not doing this. No lack of skill or observation can entirely frustrate his communicating his intention to kindred natures if he is utterly sincere. An infant communicates its joy. It is probable that the inexpressible is never felt. Stammering becomes more eloquent than oratory, a child's impulsiveness wiser than circumlocutory experience. When a single intention absorbs the whole nature, communication is direct and immediate, and makes impotence itself a means of effectiveness. So the naïveties of early art put to shame the purposeless parade of prodigious skill. Wherever there is communication there is art; but there are evil communications and there is vicious art, though, perhaps, great sincerity is incompatible with either. For an artist to be deterred by other people's demands means that he is not artist enough; it is what his reason teaches him to demand of himself that matters, though, doubtless, the good desire the approval of kindred natures. A work of art addresses the eye by means of chosen proportions; it may present any number of facts as exactly as may be, but if it offend the eye it is a mere misapplication of industry, or the illustration of a scientific treatise out of place; and those that choose ribbons well are better artists than the man that made it. Or again it may overflow with poetical thought and suggestion, or have the stuff to make a first-rate story in it; but, if it offend the eye, it is merely a misapplication of imagination, invention or learning, and the girl who puts a charming nosegay together is a better artist than he who painted it. On the other hand, though it have no more significance than a glass of wine and a loaf of bread, if the eye is rejoiced by gazing on the paint that expresses them, it is a work of art and a fine achievement. Still, it may be as fanciful as a fairy-tale, or as loaded with import as the Crucifixion; and, if it stimulates the eye to take delight in its surfaces over and above mere curiosity, it is a work of art, and great in proportion as the significance of what it conveys is brought home to us by the very quality of the stimulus that is created in return for our gaze. For painting is the result of a power to speak beautifully with paint, as poetry is of a power to express beautifully by means of words either simple things or those which demand the effort of a welltrained mind in order to be received and comprehended. The mistake made by impressionists, luminarists, and other modern artists, is that a true
