But very few men are capable of an original aesthetic emotion. Most of those who believe they experience it are like the people themselves, merely obeying the suggestion of a master, the bidding of their memories, the influence of their environment, the fashion. There is a passing beauty as precarious as popular success. A work of art extolled by the caste to-day will be despised by the caste to-morrow, and less trace of it will perhaps remain than of the work rejected by the caste and acclaimed by the people. For success is a fact whose importance increases with the dust it raises, with the number of the faithful come to accompany the cortège. The emotions of the caste and the emotions of the people are destined to the same end. Nature, which makes no leaps, makes no choice either. It is a question of making children. The sense of smell (or an analogous sense) is so highly developed in the emperor-moth, that a female egg of that rare butterfly attracts a throng of males to the spot where not one was seen before. This acuteness would be absurd if it merely served the emperor-moth to select a more delicate repast in the flowery flock or, in one way or another, to increase its pleasure and its spiritual advancement, the culture of its intelligence. It is an aid to the emperor-moth in making love. It is its aesthetic sense. However, there are human natures, less diffuse or more refractory, in which the emotions do not react upon the centre of major sensibility, either because this centre is atrophied, or because the emotional current has encountered in its course an obstacle, a dyke, an impervious barrier. Let us, without examining too closely the aptness of the analogy, avail ourselves of the commonest and most striking comparisons. An electric current is thrown into a wire for the purpose of creating motion. The wire falls supported by a bit of wood and, instead of motion, heat is generated. The train which was to have been propelled burns. So the emotion, on its way towards the genital sense which it is meant to awaken, encounters a centre of resistance. It is broken, twists back upon itself, but becomes installed; and all the emotions of the same order, which pass by the same centre, will share the same fate. A wheel was to be turned, and we have fireworks. The species was to be preserved, and we have born the idea of beauty. Aesthetic emotion, even in its purest, most disinterested form, is, then, merely a deviation of the genital emotion. Aphrodite, who urged us to her cult, no longer troubles us. The woman has vanished. Noble forms are left, agreeable lines; but a horse also is beautiful, and a lion, and an ox. Fortunate short-circuit which has permitted us to reflect, to compare, to judge! The current hurled us on towards the sister of the goddess. Now it turns us from her, for she is less fair! It might be supposed that it is in the region of the intelligence the emotional current has become diffused, thus forming that mixture
