Schopenhauer’s definition of genius is probably more accurate and more logical than that of any other writer. In his opinion, genius is the power of pre-eminent perception. The artist only exceeds his fellows in that his perception is keener; that he is able to see and understand more perfectly than others. When an able painter approaches nature in this spirit, forgetting all else, as Schopenhauer suggests, the result is usually a masterpiece. To such a painter is attributed the quality known as genius.
Taine
Taine defines art as the power of perceiving the essential character of an object. Taine says: “The character of an object strikes him [the artist] and the effect of this sensation is a strong, peculiar impression.... But art itself, which is the faculty of perceiving and expressing the leading character of objects, is as enduring as the civilization of which it is the best and earliest fruit.... To give full prominence to a leading character is the object of a work of art. It is owing to this that the closer a work of art approaches this point the more perfect it becomes; in other words, the more exactly and completely these conditions are complied with, the more elevated it becomes on the scale. Two of these conditions are necessary; it is necessary that the character should be the most notable possible and the most dominant possible.... The masterpiece is that in which the greatest force receives the greatest development. In the language of the painter, the superior work is that in which the character possessing the greatest possible value in nature receives from art all the increase in value that is possible.... It is essential, then, to closely imitate something in an object; but not everything.” After defining the essential quality by two illustrations—the illustration of the lion and the illustration of the dominant characteristics of a flat country like Holland, Taine continues: “Through its innumerable effects, you judge of the importance of this essential character. It is this which art must bring forward into proper light, and if this task devolves upon art it is because nature fails to accomplish it. In nature this essential character is simply dominant; it is the aim of art to render it predominant.... Man is sensible of this deficiency, and to remove it he has invented art.”
Froude
Froude touches upon this point in his reference to the art of the writer. He said he would turn to Shakespeare for the best history of England because of his (Shakespeare’s) absolute truth to character and event. “We wonder,” Froude wrote, “at the grandeur, the moral majesty, of some of Shakespeare’s characters, so far beyond what the noblest among ourselves can imitate, and at first thought we attribute it to the genius of the poet, who has outstripped Nature in his creations. But we are misunderstanding the power and the meaning of poetry in attributing creativeness to it in any such sense. Shakespeare created, but only as the spirit of Nature created around him, working in him as it worked abroad in those among whom he lived. The men whom he draws were such men as he saw and knew; the words they utter were such as he heard in the ordinary conversations in which he joined. At the Mermaid with Raleigh and with Sidney, and at a thousand unnamed English firesides, he found the living originals for his Prince Hals, his Orlandos, his Antonios, his Portias, his Isabellas. The closer personal acquaintance which we can form with the English of the age of Elizabeth, the more we are satisfied that Shakespeare’s great poetry is no more than the rhythmic echo of the life which it depicts.”
Baumgarten
Baumgarten concluded, from Leibnitz’ theory of a pre-established harmony and its consequence, that the world is the best possible, that nature is the highest embodiment of beauty, and that art must seek as its highest function the strictest possible imitation of nature.
Leibnitz
Bosanquet says: “The greatest degree of perfection was to be found, according to Leibnitz, in the existing universe, every other possible system being as a whole less perfect.”
