Two modes of argumentation have been used onbehalf of women’s emancipation in Western societies.Arguments in what could be called the “relational”feminist tradition maintain the doctrine of “equality in(5) difference,” or equity as distinct for equality. Theyposit that biological distinctions between the sexesresult in a necessary sexual division of labor in thefamily and throughout society and that women’s pro-creative labor is currently undervalued by society, to(10) the disadvantage of women. By contrast, the individual-ist feminist tradition emphasizes individual human rightsand celebrates women’s quest for personal autonomy,while downplaying the importance of gender roles andminimizing discussion of childbearing and its attendant(15) responsibilities.Before the late nineteenth century, these viewscoexisted within the feminist movement, often withinthe writings of the same individual.
