Thus, from the Australian and the Indian to the Hebrew, the Arab, and the Hindoo, what pleases the men in women is not their beauty, but their voluptuous rotundity; they care only for those sensual aspects which emphasize the difference between the sexes. The object of the modern wasp waist (in the minds of the class of females who, strange to say, are allowed by respectable women to set the fashion for them) is to grossly exaggerate the bust and the hips, and it is for the same reason that barbarian and Oriental girls are fattened for the marriage market. The appeal is to the appetite, not to the esthetic sense. THE CONCUPISCENCE THEORY OF BEAUTY In writing this I do not ignore the fact that many authors have held that personal beauty and sensuality are practically identical or indissolubly associated. The sober philosopher, Bain, gravely advances the opinion that, on the whole, personal beauty turns, 1, upon qualities and appearances that heighten the expression of favor or good-will; and, 2, upon qualities and appearances that suggest the endearing embrace. Eckstein expresses the same idea more coarsely by saying that "finding a thing beautiful is simply another way of expressing the manifestation of the sexual appetite." But it remained for Mantegazza to give this view the most cynical expression: "We look at woman through the prism of desire, and she looks at us in the same way; her beauty appears to us the more perfect the more it arouses our sexual desires--that is, the more voluptuous enjoyment the possession of her promises us." He adds that for this reason a man of twenty finds nearly all women beautiful.
