Aristotle

Aristotle appears in Simone de Beauvoir’s historical and philosophical account as an influential authority whose descriptions of women turn social hierarchy into an apparent fact of nature. His ideas recur across discussions of women’s status, reproduction, and sexual difference: he treats woman as deficient in relation to man, assigns her a passive role in generation, and provides a vocabulary later used to defend women’s subordination. The book examines these claims not as neutral discoveries but as interpretations shaped by a masculine order.

Identity and Intellectual Role

Aristotle is cited as a classical philosopher whose account of women became part of a durable tradition of male authority. In the book’s discussion of the universal human subject, his declaration that the female is characterized by a lack of qualities illustrates how man is made the norm and woman defined as a limitation. His formulation that women’s nature suffers from natural defectiveness makes the hierarchy seem inherent rather than socially imposed.

The argument is reinforced by the later Christian thinker Saint Thomas Aquinas, who calls woman an incomplete man and an incidental being. The juxtaposition places Aristotle within a line of philosophical claims through which woman is denied autonomous standing. Rather than being understood in herself, she is measured against the male as the essential human type. The account makes clear that such descriptions do more than insult: they establish a conceptual framework in which women’s difference can be used as evidence for their lesser status.

Sexual Difference and the Limits of Explanation

In examining theories of sexual differentiation, Beauvoir notes that most philosophies take the existence of two sexes for granted instead of explaining why reproduction must depend on them. Aristotle, she argues, offers no adequate explanation. His account invokes the cooperation of matter and form but does not establish why active and passive principles must be assigned to two different kinds of individuals.

This criticism distinguishes the significance of sexuality from the claim that sexual differentiation is logically necessary. The continuation of a species may be understood in relation to the finite lives of individuals, but it does not follow that reproduction requires two distinct sexes: a society reproducing by parthenogenesis or composed of hermaphrodites is conceivable. Aristotle’s framework, in Beauvoir’s reading, leaves the basic fact of sexual difference unexplained while later accounts treat its social meanings as if they were inevitable.

Reproduction and the Assignment of Passivity

Aristotle’s theory of conception is part of a long historical pattern in which scientific uncertainty accommodates patriarchal assumptions. In his account, the fetus results from the meeting of sperm and menstrual blood, but the woman supplies passive material while the male principle provides strength, activity, movement, and life. Hippocrates’ related doctrine also assigns weakness to the female seed and strength to the male one. These ideas persisted through the Middle Ages and into the modern period.

Beauvoir traces how later observation unsettled these explanations. The female reproductive glands were identified as ovaries; the mammalian egg was recognized in 1827; and, in 1877, sperm was observed penetrating a starfish egg. The symmetry of the gametes’ nuclei was then established, and their fusion was analyzed in detail in 1883. This history matters to Aristotle’s place in the argument because claims about biological passivity outlasted the evidence that had been used to support them.

Even after the ovum was recognized as an active principle, it continued to be contrasted with the supposedly greater agility of sperm. Beauvoir notes that discoveries of parthenogenesis later prompted the opposite overreach: some scientists reduced the male contribution to a mere physicochemical agent and speculated that it might eventually become unnecessary. She rejects both assumptions. Asexual multiplication, parthenogenesis, and sexual reproduction coexist; none establishes a universal hierarchy between the sexes.

From Philosophical Theory to Patriarchal Authority

Aristotle’s account also appears in Beauvoir’s discussion of the transition from matrilineal descent to paternal authority. As men claimed posterity and inheritance for themselves, Aristotle’s view of woman as mere matter gave philosophical expression to a broader assertion of male power. His description of the male principle as better and more divine, in Beauvoir’s analysis, exceeds what was known about conception: it turns a claim about reproduction into a claim about authority.

The book connects such theories to the practical organization of property and family. Under a system in which a man claims children as heirs and transmits rights and possessions, women are relegated to procreation and secondary tasks. Aristotle’s ideas do not alone cause this transformation, but they help make it appear justified: male sovereignty is represented not as a historical arrangement but as the natural consequence of male activity and female passivity.

Women’s Social Position in Classical Greece

Beauvoir situates Aristotle’s views within the restrictive conditions of Greek women’s lives. In the classical period, women were confined to the home and expected to obey men. Aristotle’s assertion that a woman has the capacity to deliberate but is weak and powerless offers a concise philosophical rationale for that status. His position is presented as representative of the prevailing view, in contrast to Plato’s exceptional proposals for girls’ education and women’s participation in civic administration.

The surrounding evidence also shows how domestic expectations and misogynistic judgments reinforced each other. A wife was expected to be an attentive, prudent, economical housekeeper, while Greek writers repeatedly condemned women for failing to embody the qualities demanded of them. Beauvoir notes that women had few recognized rights, yet could still possess authority within the household and resist a husband’s wishes. Aristotle’s account thus belongs to a social order whose claims of female weakness coexisted with the demands that women perform essential domestic labor and submit to male rule.
