Without exculpating Aristotle from charges of misogyny, Deslauriers contextualizes his explanations of the role and origin of female animals in his biology and the role of women in his political philosophy; she shows how Aristotle developed these views and the importance they hold for his wider philosophical commitments. She then explores how Aristotle might have seen the link between the physiology of sex and the bearing it has on political life. She ultimately argues that in Aristotle's conception of sexual difference in biology and politics, there is a tension between his view of the inferiority of female bodies and women and his commitment to the idea that females and women are valuable both for generation and for the political life characteristic of human beings. In this tension she finds a difference between Aristotle and his predecessors: while previous accounts associate sexual difference with affliction, Aristotle sees sexual difference as a benefit, both to a species and a political community. This volume will be of interest to philosophers and students interested in ancient philosophy, feminist philosophy, as well as those studying moral and political philosophy.
