n addition to age, gender is one of the universal dimensions on which status differences are based. Unlike sex, which is a biological concept, gender is a social construct specifying the socially and culturally prescribed roles that men and women are to follow. According to Gerda Lerner in The Creation of Patriarchy, gender is the "costume, a mask, a straitjacket in which men and women dance their unequal dance" (p.238). As Alan Wolfe observed in "The Gender Question" (The New Republic, June 6:27-34), "of all the ways that one group has systematically mistreated another, none is more deeply rooted than the way men have subordinated women. All other discriminations pale by contrast." Lerner argues that the subordination of women preceded all other subordinations and that to rid ourselves of all of those other "isms"--racism, classism, ageism, etc.--it is sexism that must first be eradicated.
