Existential morality
The Second SexExistentialist morality is the book’s stated ethical framework for examining women’s situation. It treats freedom as something realized through projects and continued movement toward an open future; against that standard, the central problem is how a woman, an autonomous freedom, can live in a world that seeks to constitute her as the Other and confine her to immanence.
Ethical Standard: Freedom Rather Than Happiness
The framework begins by rejecting happiness as a measure of social arrangements. Happiness cannot be reliably known or measured from the outside, and it is easy to label as happy a situation one wishes to impose on others. A housewife cannot simply be assumed happier than a working woman, any more than a woman living in a harem can be presumed happier than a woman with the vote. Such judgments risk treating stillness and restricted possibility as contentment.
Instead, the book judges institutions by the concrete opportunities they give individuals, while distinguishing private good from an abstract public interest. Its chosen standard is existentialist morality: a subject realizes freedom through projects and through continual surpassing toward other freedoms. Present existence gains its justification not from a fixed condition but from expansion toward a future that remains open.
Transcendence, Immanence, and Oppression
The moral distinction at the framework’s center is between transcendence and immanence. When transcendence lapses into immanence, existence is reduced to a fixed, thing-like condition and freedom to mere fact. If a subject consents to this fall, the book calls it a moral failure; when it is imposed, it becomes frustration and oppression. The same restriction is therefore ethically significant both as a surrendered possibility and as an externally enforced condition.
Women’s situation makes this conflict especially sharp. Like all human beings, women are autonomous freedoms, yet they encounter a world in which men insist that they assume the position of the Other. They are treated as objects and confined to immanence, while their attempts to transcend that assigned position are subordinated to another consciousness regarded as essential and sovereign. The resulting drama lies between a subject’s fundamental claim to be essential and the social situation that declares her inessential.
The Body as Situation, Not Destiny
This approach does not deny the importance of biology. The book examines menstrual and reproductive processes as consequential elements of women’s situation: the body can be experienced as alienated, and reproductive demands can weigh heavily on individual life. Yet such experiences do not establish a fixed destiny. Biological data alone cannot explain why women are made the Other or justify their subordination.
The body has lived significance through consciousness, action, and society. It is not simply a biological fact detached from its circumstances: social customs, laws, values, and economic and psychological contexts shape how bodily processes are experienced and interpreted. The central question is therefore not only what nature has given women, but how history and society have taken up that nature and made it part of women’s human situation.
The Inquiry and Its Political Stakes
The framework organizes the book’s inquiry. It first examines women biologically, psychoanalytically, and through historical materialism, then asks how feminine reality has been constituted, why woman has been defined as the Other, and what consequences follow. It also turns to the world as women are offered it and to the difficulties they face when they seek to leave the sphere assigned to them and participate in human coexistence.
The decisive question is consequently how a human being can realize herself within the feminine condition: which paths remain open, which become dead ends, and how independence can be found within dependence. By defining possibilities in terms of freedom rather than happiness, existentialist morality refuses to mistake accommodation to constraint for fulfillment. It makes the concrete expansion of women’s agency the measure of the institutions and arrangements under examination.
