Read the passage, then answer the question. The argument is, that different natures have different uses, and the natures of men and women are said to differ. . . . We do not consider that the difference may be purely nominal and accidental; for example, a bald man and a hairy man are opposed in a single point of view, but you cannot infer that because a bald man is a cobbler a hairy man ought not to be a cobbler.
–The Republic, Plato
