Humanity is male, and man defines woman, not in herself, but in relation to himself

“Humanity is male, and man defines woman, not in herself, but in relation to himself” names the central asymmetry in Simone de Beauvoir’s analysis of sexual difference: man appears as the universal human subject, while woman is understood through her relation to him. The expression joins a philosophical claim about who counts as the norm to a historical account of how women are made to live as the inessential Other.

Meaning and Formulation

De Beauvoir contrasts the apparently symmetrical categories of masculine and feminine with a structure in which only one term is treated as universal. In ordinary language, the masculine can stand for humanity as a whole; woman, by contrast, is marked by sex and treated as a limited particularity. Men can regard themselves as individuals without first defining themselves as male, whereas a woman is routinely made to answer for her sex. The expression’s decisive point is not simply that women are described differently, but that their relation to themselves is displaced by a definition made from the male point of view.

The surrounding argument describes this hierarchy through the opposition between Subject and Other. Man is established as the essential, self-sufficient term; woman becomes the relative being, intelligible chiefly in relation to man. De Beauvoir invokes familiar accounts of woman as incomplete or deficient and shows how they present a social hierarchy as though it followed naturally from the body. The resulting definition does not recognize woman as an autonomous being in her own right.

The Other and Unequal Reciprocity

The category of the Other is not unique to relations between the sexes. Groups define themselves against outsiders, and relations among villages, nations, classes, and other communities can shift as each claims to be the essential term. In those relations, opposing groups may assert their own subjecthood and expose the other side’s claim to universality as relative. De Beauvoir’s question is why this reciprocity has not been established between women and men: why one term has become the essential one while the other is expected to accept an external definition.

Her answer emphasizes history and social organization rather than a simple numerical or biological explanation. Women are not a numerical minority, and their subordination cannot be traced to a single dated event in the way some other histories of oppression can. Women have always lived among men and remain closely bound to them through family, work, economic interests, and social conditions. They do not, in general, possess an independent shared space or the solidarity that could enable them to act collectively as a separate political subject.

That dispersed position is also divided by class and race. Bourgeois women may be aligned more closely with bourgeois men than with working women; white women may share interests with white men rather than with Black women. The ties connecting women to men are therefore not equivalent to a separation between two independent groups. The couple is a social unit whose members are bound to each other, even as their positions within it are unequal. This dependence helps explain why the Other does not readily turn around and establish itself as the One.

Historical and Material Conditions

The expression also illuminates the distance between a proclaimed equality and women’s lived conditions. In the nineteenth century, women’s entry into paid labor gave their demands an economic basis, while employers benefited from the low wages women were made to accept. Male workers could then view women as competitors rather than allies. De Beauvoir argues that women’s integration into unions helped them defend their interests and made it possible to form coalitions instead of reproducing that opposition.

Economic dependence is reinforced by the unequal distribution of domestic labor. A peasant woman might carry substantial responsibilities in the household economy and be respected within it, yet also perform field labor, care for animals and children, prepare meals, and manage the home. Her workday could begin at dawn and continue into the evening, leaving little time for rest or social life. The concrete burden shows how a woman can be indispensable to a household without being recognized as an independent subject on equal terms.

The same hierarchy shapes expectations around work and marriage. Girls are still directed toward marriage rather than their own development, and a young woman may be encouraged to imagine a husband as the route to happiness and a higher social position. That promise can weaken her investment in professional training; resulting disadvantage then makes marriage appear more necessary. Even when women work, the burden of family life remains heavier for them, while economic inequality and the prestige of masculine support make dependence seem attractive or unavoidable.

Bodies, Freedom, and Repetition

De Beauvoir’s argument does not deny women’s bodily particularity; it disputes the conversion of bodily difference into a fixed social destiny. In her account of puberty, a girl’s future social role can seem to arrive through her body before she has chosen it. Menstruation may become a source of shame and anxiety, and the girl may interpret her body as suspect or sick. The analysis connects that distress to the perspective through which her body is understood: a biological condition becomes a handicap within a situation that already restricts her outlets and encourages an inferiority complex.

This account belongs to a broader existentialist distinction between transcendence and immanence. A subject realizes freedom through projects that reach beyond what is given; when a person is confined to repetition and treated as an object, existence is restricted to immanence. De Beauvoir describes woman’s situation as a conflict between her autonomy as a human subject and the social demand that she assume herself as Other. The question is not whether she can be happy in a situation assigned to her, but what possibilities she has to act freely within and against it.

Domestic work makes that conflict visible in time as well as in status. Housework repeats tasks that must be done again as soon as they are finished: dishes, dusting, and mending do not accumulate into a lasting conquest. The recurring labor can resemble the torment of Sisyphus, while a young girl watching her mother clean sees the future as an endless return to the same duties. The image gives the expression a daily scale: the male norm is sustained not only by explicit judgments about women, but by arrangements that reserve open-ended projects for some and recurrent maintenance for others.

Scope and Continuing Significance

The expression links the intimate and the institutional. De Beauvoir’s account of women as the Other draws on a philosophical opposition between subject and object, but it also traces that opposition through labor, family, education, economic dependence, and bodily expectations. Its emphasis is on how a position made by social relations comes to look like a natural fact, and how that appearance can help preserve the conditions that produced it.

The argument also places women’s subordination alongside the treatment of other groups reduced to abstract types. De Beauvoir compares the justifications used for sexism with those used to subordinate Black people and Jews, while distinguishing the differing histories and positions involved. Such comparisons sharpen the point that ruling groups can define an oppressed group by qualities the ruling order itself has imposed, then cite those supposed qualities as evidence that the hierarchy is deserved.

For De Beauvoir, the expression is therefore a diagnosis rather than an assertion that women are inherently relative or dependent. Woman is made to encounter herself in a world organized around masculine sovereignty, even though she is, like other human beings, an autonomous freedom. The possibility of change rests on recognizing this imposed position as a situation with historical and material conditions, not as an immutable truth about what women are.
