1908-1986 CE
One is not born, but rather becomes, a woman — gender is not biological destiny but social construction, and women's oppression stems from being defined as the inessential Other.
Simone Lucie Ernestine Marie Bertrand de Beauvoir was born on 9 January 1908 in Paris, the elder of two daughters. Her father, Georges Bertrand de Beauvoir, was a legal secretary from minor nobility; her mother, Françoise Brasseur, was a wealthy banker’s daughter. The family was bourgeois, Catholic, conventional. But WWI and its aftermath destroyed their finances. By Simone’s teens, the family was impoverished gentility — keeping up appearances while struggling.
Simone attended Catholic schools, excelled academically, and was pious initially. But at fourteen, she lost faith. She wrote in her diary: “God is dead.” She remained atheist lifelong. Her father, liberal about religion, encouraged her intellectualism. He told her: “You have a man’s brain.” She took it as compliment then; later, she’d question the assumption.
She studied mathematics and literature at the Institut Catholique and Sorbonne. In 1926, she entered the École Normale Supérieure, France’s elite institution. There were few women; she was extraordinary. She read philosophy voraciously — Descartes, Kant, Spinoza, Leibniz — but found them abstract, disconnected from life. When she discovered phenomenology (Husserl) and existentialism (Heidegger, later Sartre), she found philosophy grounded in lived experience.
In 1929, she took the agrégation in philosophy. She ranked second; Jean-Paul Sartre first. They had met earlier and become close. The examiners noted: her work was more precise and rigorous; his was more original. Some historians believe she deserved first but wasn’t given it because she was a woman. Sartre himself said: “She should have been first.”
Sartre proposed marriage. She refused. Instead, they formed a “two-year lease” — a contract to stay together for two years, then reevaluate. The lease kept renewing for fifty-one years. Their pact: no marriage, no children, absolute honesty, primary commitment to each other, but freedom for other relationships (“contingent” loves). She called theirs a “necessary” love — essential, permanent. Others were contingent — meaningful but not foundational.
From 1931-43, she taught philosophy at lycées in Marseille, Rouen, and Paris. She was brilliant teacher but also involved in inappropriate relationships with students. In Rouen, she had affairs with Olga Kosakiewicz and Louise Védrine, both students — clear abuse of power, though not illegal then. She later introduced Olga to Sartre; they formed a ménage à trois (1934-37) that caused intense jealousy and pain. She wrote about it in her first novel, She Came to Stay (1943) — existentialist exploration of the Other through triangulated relationships.
The 1930s were her apprentice years. She wrote but published little. She traveled with Sartre — Greece, Italy, Morocco. She read, thought, lived. She saw herself as minor figure to Sartre’s genius. This changed during WWII.
Under German occupation, she continued teaching. She and Sartre lived through the Occupation writing, reading, engaging with resistance peripherally (more symbolic than dangerous). In 1943, she was fired from teaching for “corrupting a minor” (seducing Nathalie Sorokine, a student). The charge was true, though the firing was also political — punishment for resistance sympathies.
She Came to Stay (1943) established her as novelist. The Marquis de Sade (1944-47) and Pyrrhus and Cineas (1944) showed her as philosopher. But The Ethics of Ambiguity (1947) was breakthrough: existentialist ethics grounded in concrete situations. Against Sartre’s abstract freedom, she emphasized ambiguity — we’re both free and constrained, subject and object, transcendent and situated. Ethics means recognizing this ambiguity and acting to increase freedom — ours and others’.
Then came The Second Sex (Le Deuxième Sexe, 1949), her masterwork. She’d wondered: what had it meant in her life to be a woman? She researched biology, history, mythology, psychoanalysis, literature. The result: two volumes, over 900 pages, analyzing women’s oppression.
The opening line became famous: “One is not born, but rather becomes, a woman.” Sex is biological; gender is social construction. Women are made into the feminine through education, culture, ideology. Men are defined as Subject, Absolute, transcendent; women as Other, relative, immanent. Women are defined in relation to men, never for themselves. Myths (Virgin Mary, witch, mother, whore) trap women in limited roles. Women’s bodies (menstruation, pregnancy, nursing) are made burdens by societies refusing to accommodate them. Marriage and maternity become prisons when society offers women no other paths to validation.
The book scandalized France. Camus called it “ridiculous.” François Mauriac said: “Now I know everything about your boss’s vagina.” The Vatican put it on the Index of Forbidden Books. But young women saw themselves in it. It became manifesto for second-wave feminism.
Beauvoir was surprised by the reaction. She didn’t consider herself feminist initially — she thought Marxist revolution would solve women’s oppression. But engaging with women readers worldwide radicalized her. By the 1970s, she embraced feminism fully.
Through the 1950s-60s, she wrote novels (The Mandarins, 1954, won Prix Goncourt — roman à clef about postwar Parisian intellectuals including Sartre, Camus, herself) and memoirs (Memoirs of a Dutiful Daughter, 1958; The Prime of Life, 1960; Force of Circumstance, 1963). The memoirs were extraordinary — unflinching honesty about her life, loves, thoughts, doubts. She didn’t hide affairs, conflicts, or failures.
She traveled extensively: USA (1947, romance with Nelson Algren, American novelist — passionate affair that ended painfully when she refused to leave Sartre), China (1955), Cuba (1960), USSR, Brazil. She wrote travel books combining observation and political analysis.
In 1970, she published The Coming of Age (La Vieillesse) — phenomenology of aging exposing how society marginalizes and dehumanizes the elderly. Like The Second Sex did for gender, it revealed aging as social construction, not natural decline.
The 1970s brought feminist activism. She signed manifestos for abortion rights (illegal in France until 1975), became president of Choisir (abortion rights organization), supported women’s liberation movement. She declared: “I am a feminist” — embracing the label she’d once avoided.
In 1980, Sartre died. Beauvoir was devastated. She wrote Adieux: A Farewell to Sartre (1981) — brutal, loving account of his final years’ physical and mental decline. Critics called it betrayal; she called it honesty. She couldn’t lie about the man she’d loved for fifty years.
She adopted Sylvie Le Bon, a philosophy teacher, as her daughter (1980) — making her literary executor and heir. Some saw it as replacement for Sartre; she saw it as ensuring her work’s future.
She died on 14 April 1986, six years after Sartre, and was buried beside him in Montparnasse Cemetery. Thousands attended — feminists, students, intellectuals, admirers. She had transformed philosophy by making women’s experience philosophical, created feminist existentialism, and lived freedom’s complexities publicly.
"One is not born, but rather becomes, a woman. No biological, psychological, or economic fate determines the figure that the human female presents in society."
— The Second Sex (1949), Volume II — the foundational statement of constructivist feminism
"The most sympathetic of men never fully comprehend woman's concrete situation."
— The Second Sex — on the limits of male understanding, even among allies
"Representation of the world, like the world itself, is the work of men; they describe it from their own point of view, which they confuse with absolute truth."
— The Second Sex — on male perspective presented as universal, neutral truth
Beauvoir’s philosophy integrates existentialism and feminism, creating existentialist feminism that analyzes women’s concrete situations.
One becomes a woman: The Second Sex’s central claim is that gender is not biological destiny but social construction. “One is not born, but rather becomes, a woman.” Biological sex (female body) doesn’t determine gender (feminine psychology, behavior, roles). Society constructs femininity through education, culture, myths, and institutions. Girls learn to be passive, modest, nurturing; boys learn to be active, ambitious, dominating. This isn’t natural but imposed.
Beauvoir examines how this happens. Childhood: girls are given dolls (immanence, repetition, care for others); boys are given tools (transcendence, creation, mastery). Adolescence: girls’ bodies become problems (menstruation as curse, sexuality as dangerous); boys’ bodies become instruments (strength, agency). Adulthood: women are channeled into marriage and maternity; men into public achievement. At every stage, women are defined in relation to men, never for themselves.
Women as Other: Beauvoir applies Hegel’s master-slave dialectic and Sartre’s being-for-others to gender. Men are Subject, Self, Absolute; women are Other, Object, inessential. Men define themselves as human; women are defined as “not-men,” the second sex. This is asymmetrical: men are unmarked category (humanity); women are marked (the feminine). Man is essential; woman is inessential. He is One; she is Other.
This Othering operates through reciprocity failure. Normally, consciousness recognizes the other as equally conscious (I’m Other to you; you’re Other to me). But with gender, reciprocity breaks: men define women as Other without recognizing women’s subjectivity. Women internalize this, seeing themselves through men’s eyes, accepting object-status.
Why do women accept it? Beauvoir explores complicity. Becoming Other offers compensations: men’s protection, economic support, romantic idealization, maternal valorization. Women are rewarded for femininity, punished for assertion. Many choose immanence over the difficult freedom of transcendence. This is bad faith — denying freedom, accepting object-status. But Beauvoir emphasizes: society systematically constrains women’s choices. Blaming women ignores the situation.
Transcendence versus immanence: Existentialism says humans are beings who transcend — we project beyond ourselves through projects, create meaning, change the world. But women are confined to immanence — repetition, stagnation, maintenance. Men build, create, achieve; women clean the house (tomorrow it’s dirty again), cook meals (they’re eaten, forgotten), raise children (who leave). Immanence is Sisyphean — endless repetition without transcendence.
This isn’t because women’s activities are inherently inferior. It’s because society denies women transcendence. Women who attempt it (careers, art, politics) face obstacles: lack of education, economic dependence, domestic duties, social disapproval, internalized limitations. The exceptional woman who transcends is deemed “unfeminine” — implying transcendence and femininity are incompatible.
The ethics of ambiguity: In The Ethics of Ambiguity, Beauvoir develops existentialist ethics emphasizing situated freedom. Against Sartre’s sometimes abstract freedom, she stresses: we’re both free and situated. Our freedom is constrained by facticity — body, history, society, language. We’re ambiguous beings: neither pure freedom (Sartre sometimes suggested) nor pure determinism (Marxism sometimes implied).
Ethics means recognizing this ambiguity. We must: (1) Acknowledge our freedom and responsibility. (2) Acknowledge our situation’s constraints. (3) Act to expand freedom — ours and others’. Oppression is denying others’ freedom, reducing them to objects. Liberation is enabling transcendence. Beauvoir emphasizes: my freedom depends on others’ freedom. If others are enslaved, I’m diminished. Genuine freedom is collective.
She identifies several existential attitudes. The sub-man: denies freedom, lives mechanically. The serious man: invests in external values (God, nation, money), fleeing freedom. The nihilist: recognizes contingency, despairs, destroys. The adventurer: seeks individual freedom, ignoring others. The moral individual: recognizes ambiguity, acts to increase freedom responsibly. This framework influenced later existentialist and feminist ethics.
Concrete situations: Beauvoir’s major contribution is analyzing concrete situations. Sartre discussed freedom abstractly; Beauvoir examined how class, race, age, gender create different situations with different possibilities. A working-class woman has fewer possibilities than a bourgeois man. Pretending everyone is equally free ignores structural oppression.
She applies this to women’s situations. The girl child is taught passivity, the adolescent girl experiences her body as burden, the married woman is economically dependent, the mother is exhausted by unpaid labor, the aging woman becomes invisible. Each situation constrains transcendence. Liberation requires changing situations — not just consciousness but material conditions, institutions, culture.
Myth and femininity: The Second Sex analyzes myths of femininity — Virgin Mary (purity, self-sacrifice), mother (devotion, self-abnegation), prostitute (sexuality as service), muse (inspiring men’s creativity), eternal feminine (mysterious, unknowable). These myths idealize women while denying their subjectivity. Women are pedestalized and imprisoned.
Men create these myths projecting their desires and fears onto women. Woman becomes Nature, Mystery, Other — everything man is not. She’s both virgin and whore, mother and seductress, angel and demon. These contradictory images reflect male ambivalence, not women’s reality. But women internalize the myths, trying to embody them, denying their own subjectivity in the process.
Sexuality and the body: Beauvoir analyzes women’s embodiment phenomenologically. Menstruation, pregnancy, nursing — these aren’t inherently limiting. But society treats them as disabilities, refusing to accommodate women’s bodies. Workplace doesn’t allow for pregnancy; public spaces lack nursing facilities; menstruation is shameful. Women’s bodies become problems because society constructs them that way.
She also discusses sexuality. Women’s sexuality is defined by men — as passive reception, as object of male desire. The virgin is valued; the sexually experienced woman is degraded. Sex is something done to women, not something women do. Liberation requires women claiming sexual subjectivity, defining pleasure on their terms, not men’s.
Lesbianism: Beauvoir discusses lesbianism (controversial in 1949) as legitimate choice, not sickness. She argues lesbianism can be flight from men or authentic choice of women. But she’s ambivalent — sometimes suggesting it’s immature, sometimes defending it as valid. Her personal bisexuality remained mostly private (though evident in her memoirs).
Marriage and maternity: Beauvoir critiques marriage as institution enslaving women. Legal marriage makes women economically dependent, sexually available, domestic servants. She doesn’t oppose partnership but coercive institution. Similarly, she critiques compulsory motherhood, not motherhood itself. Women should choose if/when to have children, not be forced by biology, law, or social pressure.
Later feminism: Initially, Beauvoir thought Marxist revolution would liberate women — class struggle was primary. But engaging with women readers worldwide convinced her: women’s oppression requires specific struggle. By 1970s, she was radical feminist, supporting women’s liberation movement, abortion rights, lesbian rights. She declared: “Women must learn solidarity. Men won’t liberate them.”
Limits and critiques: The Second Sex has limitations. It’s Eurocentric — focuses on French/Western women, though Beauvoir traveled and tried to include other cultures. It’s class-biased — Beauvoir was bourgeois, sometimes dismissive of working-class women and housewives. It’s heteronormative in places — despite discussing lesbianism, she privileges heterosexual relationships. It sometimes essentializes femininity in criticizing it. And Beauvoir’s personal life contradicts some positions — her affairs with students involved problematic power dynamics; her childlessness was presented as liberation but could seem judgmental toward mothers.
Later feminists critiqued and extended her work. Intersectional feminism (Kimberlé Crenshaw) shows gender intersects with race, class, sexuality — Beauvoir recognized this partially but inadequately. Care ethics feminists (Carol Gilligan) reclaim values Beauvoir associated with oppression. Queer theory (Judith Butler) radicalizes her constructivism. Postcolonial feminists critique her Eurocentrism. But all engage Beauvoir because she made women’s experience philosophically central.
