This article defends Aristotle and sociobiology against their feminist
critics by arguing that a biological conception of human nature right
ly understood can support feminism. Aristotle's telelogical biology is
not sexist. On the contrary, his biology suggests lines of argument t
hat could vindicate feminism in some form. By arguing for marital frie
ndship as the standard for judging spousal relationships, and by defen
ding family life, and particularly maternal caregiving, as the natural
root of all sociality and politics, Aristotle elevates the claims of
women and suggests that the fullest human excellence would combine mas
culine and feminine inclinations. Aristotle's functional teleology sus
tains a conception of natural human needs and powers as universal desp
ite the variability of cultures. Without such an understanding of a un
iversal human nature, feminists are tempted to adopt a cultural relati
vism that renders their critique of patriarchy incoherent. Furthermore
, this defense of Aristotle applies as well to sociobiological account
s of human sexual nature.
