Quote from : The Beauty Myth Book

Women are mere "beauties" in men's culture so that culture can be kept male. When women in culture show character, they are not desirable, as opposed to the desirable. A beautiful heroine is a contradiction in terms, since heroism is about individuality, interesting and ever changing, while "beauty" is generic, boring, and inert. While culture works out moral dilemmas, "beauty" is amoral: If a woman is born resembling an art object, it is an accident of nature, a fickle consensus of mass perception, a peculiar coincidence--but it is not a moral act. From the "beauties" in male culture, women learn a bitter amoral lesson--that the moral lessons of their culture exclude them.
