Although some feeling for beauty is perhaps universal among men, the same cannot be said of the understanding of beauty. The average man, who may exercise considerable taste in personal adornment, in the decoration of the home, or in the choice of poetry and painting, is at a loss when called upon to tell what art is or to explain why he calls one thing “beautiful” and another “ugly.” Even the artist and the connoisseur, skilled to produce or accurate in judgment, are often wanting in clear and consistent ideas about their own works or appreciations. Here, as elsewhere, we meet the contrast between feeling and doing, on the one hand, and knowing, on the other. Just as practical men are frequently unable to describe or justify their most successful methods or undertakings, just as many people who astonish us with their fineness and freedom in the art of living are strangely wanting in clear thoughts about themselves and the life which they lead so admirably, so in the world of beauty, the men who do and appreciate are not always the ones who understand.
