The Ethics of Ambiguity
The Stanford Encyclopedia of Philosophy describes The Second Sex as correcting, reworking, and materially situating the more abstract analysis of The Ethics of Ambiguity.

Beauvoir's thousand-page 1949 argument that femininity is made and not born — the founding book of second-wave feminism and the century's most influential work of feminist philosophy.
Simone de Beauvoir's Le Deuxième sexe is the founding book of second-wave feminism. Gallimard published it in two volumes in 1949 (volume one, Facts and Myths, in May; volume two, Lived Experience, in November). Roughly a thousand pages long, it argues — famously in the second volume's opening line, 'One is not born, but rather becomes, a woman' — that womanhood is a social situation rather than a biological essence, and that the whole history of Western thought has treated the female as the definitive Other against which the male sets himself as the subject. Sold twenty-two thousand copies in its first week in Paris; placed on the Vatican's Index of Forbidden Books in 1956; and has been the ground text of every subsequent argument about women's position — from Betty Friedan and Kate Millett to Judith Butler and Angela Davis — for the seventy-five years since.
Beauvoir wrote Le Deuxième sexe between the autumn of 1946 and the spring of 1949, working in cafés on the Left Bank and at the National Library. She had originally set out to write a short essay about herself — what did it mean to have been born a girl? — and discovered, in the reading she did to answer the question, that the reading was the book. Gallimard published the two volumes six months apart in 1949. The first volume was immediately attacked by François Mauriac in Le Figaro, by the Vatican's Osservatore Romano, and by half the Paris literary press; the second was attacked more sharply. Beauvoir's mail for the next year contained letters calling her a nymphomaniac, a lesbian, a Marxist, a bourgeois, and (from the readers she was actually reaching) 'the woman who wrote the book that changed my life.'
The book's Anglophone reception was disfigured for fifty-six years by H.M. Parshley's 1953 English translation. Parshley — a Smith College zoologist working from a French text he did not fully read — cut roughly fifteen per cent of the original (all of it argumentative content), consolidated Beauvoir's paragraph structure, and translated her philosophical vocabulary as if it were general essayistic prose. Every anglophone reader from Betty Friedan to Kate Millett to Judith Butler read The Second Sex through Parshley's abridgment. Constance Borde and Sheila Malovany-Chevallier's complete English translation only appeared from Knopf in 2009. Serious argument about the book in English continues to run behind the two translations at once.
The argument works in two directions. Volume one refutes the explanations — biological, psychoanalytic, historical materialist — that had been used to make women's subordination look like a natural fact. Volume two then works through the situation as a woman lives it, from childhood through old age, and closes with an argument that legal rights alone are not sufficient. What matters, Beauvoir argues in the final chapter, is that women achieve economic independence, that men be raised to see women as ends rather than instruments, and that men and women be free to recognise each other as separate subjects.
Volume one opens with an introduction so influential it is now printed as a stand-alone essay in the anthologies. Beauvoir names the question — what is a woman? — and observes that the question would be senseless if asked about men, because a man is a human subject by default. Woman, by contrast, is defined always in relation to man: as his relative and subordinate Other. The rest of volume one then works through the three explanations that had, since the mid-nineteenth century, been used to justify this arrangement as natural. The first part, Destiny, refutes them in turn: biological explanations (women are not their ovaries), psychoanalytic explanations (Freud's account of women as failed men substitutes a male norm for an argument), historical materialist explanations (Engels's account is closer to the truth but underrates the specificity of what happens between the sexes). The second part, History, is a two-hundred-page survey of women's position from nomadic prehistory through Greek and Roman law, medieval Christianity, the querelle des femmes, the French Revolution, industrial capitalism, and the suffragist movements. The third part, Myths, reads the woman-as-myth in five male authors — Henry de Montherlant, D.H. Lawrence, Paul Claudel, André Breton, Stendhal — and closes with a chapter on the general myth of the eternal feminine.
Volume two, Lived Experience, moves from myths and structures to what a woman actually lives. It opens on the sentence Beauvoir is now inseparable from — 'One is not born, but rather becomes, a woman' — and proceeds through the four parts of the volume. Formation covers the girl's earliest years, the discovery of the difference between the sexes, the young girl and her early self-image, sexual initiation, and the lesbian (whose situation Beauvoir treats with more nuance than her critics allowed for). Situation covers the married woman, the mother, the woman in society, the prostitute and the hetaira (courtesan), the middle-aged woman, the woman's overall situation and its shaping of character. Justifications is a shorter part reading three specific patterns — narcissism, being in love, and mysticism — as ways women have tried to give their subordinate position a meaning. The final part, Toward Liberation, is only two chapters long: one on 'the independent woman' (the working woman, the writer, the political actor) and a conclusion titled simply 'Conclusion.'
The Conclusion is Beauvoir's argument in twelve pages. Legal rights — the vote, the right to work, the right to divorce, the right to abortion — are necessary but not sufficient. What is required is: economic independence for every woman, in a labour market that does not treat her work as marginal; a raising of men that teaches them to see women as ends rather than instruments; and — the argument Beauvoir carries from The Ethics of Ambiguity two years earlier — a relation between the sexes in which each recognises the other as a separate subject rather than as a projection of the self. She closes on a line that is often misread as bland but is in fact the whole book compressed: 'It is by working together in fraternity that men and women will clearly bring about their liberation.' The Second Sex is not a manifesto for one sex against the other. It is a manifesto for the abolition of the position of Other altogether.
The two-volume structure means that The Second Sex has, technically, two endings. Volume one, Facts and Myths, closes on the myths chapter with the observation that every myth about the eternal feminine functions to relieve men of the obligation of encountering actual women. Volume two, Lived Experience, closes on the twelve-page Conclusion described above. The book as a whole ends on the argument that legal rights alone are not sufficient — that liberation requires economic independence, an altered raising of men, and a mutual recognition of subjectivity between the sexes. The final line asks men and women to bring about their liberation together.
The Second Sex is Beauvoir's most influential book. Betty Friedan's The Feminine Mystique (1963) was written by an American reader working entirely from Parshley's abridged translation. Kate Millett's Sexual Politics (1970) is a direct extension of Beauvoir's Myths section. Angela Davis, Judith Butler, Adrienne Rich, and Susan Brownmiller all worked from The Second Sex. Judith Butler's Gender Trouble (1990) opens with an explicit reference to the 'One is not born a woman' sentence and to Beauvoir. Every major argument in Anglophone feminist theory since 1949 has, at some point, either extended, refined, or objected to something The Second Sex first put in place.
In the introduction, Beauvoir turns a familiar interruption into a problem about authority. When a man explains her opinion by her sex, she can defend the argument's truth, but she cannot answer symmetrically: his masculinity is treated as neutral rather than as a limitation. The exchange reveals why simply admitting women to a discussion does not guarantee equal standing within it. One speaker is allowed to represent reason itself; the other must first escape a label. The imagined seminar gives visible form to that unequal burden of proving one's right to think.
The conclusion treats economic independence as indispensable but insufficient on its own. Beauvoir moves from earning a living to the education, expectations and everyday relationships that make independence usable. Her account therefore asks for more than a woman occupying a formerly male position: it asks what conditions would let both people act without turning the other into a dependent or a reflection of themselves. The shared drawing is an imagined analogy for this reciprocity. Working together need not erase individuality; her closing argument allows each person to remain distinct while recognising the other's freedom.
One is not born, but rather becomes, a woman.On ne naît pas femme : on le devient.
All oppression creates a state of war.
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.

Beauvoir returns to The Second Sex's analysis of people made Other, applying a comparable method and scope to the social construction and lived experience of old age.
It is the founding book of second-wave feminism and the ground text every subsequent feminist argument — from Betty Friedan to Judith Butler — has extended, refined, or objected to.
Read the introduction to volume one and the Conclusion to volume two first if the full thousand pages feel too large, then use the section headings to choose a path through the evidence.
The 2009 Constance Borde and Sheila Malovany-Chevallier translation is the one to read — H.M. Parshley's 1953 translation, which every anglophone reader from Friedan to Butler used, cut roughly fifteen per cent of the book and stripped out much of Beauvoir's philosophical vocabulary. Serious argument about The Second Sex in English continues to run behind two different translations at once.

Beauvoir's six-hundred-page 1970 study of old age — the companion volume to The Second Sex, arguing that Western societies treat their elderly as a scandal to be hidden and that this is a decision, not a fact.
Read our takeBeauvoir's thousand-page 1949 argument that woman is defined always as man's relative and subordinate Other, that this position is socially produced rather than biologically given, and that its abolition requires economic independence, an altered raising of men, and mutual recognition of subjectivity between the sexes. It is the founding book of second-wave feminism.
Gallimard published Le Deuxième sexe in two volumes in Paris in 1949 — Volume One (Les faits et les mythes) in May, Volume Two (L'expérience vécue) in November. It sold roughly twenty-two thousand copies in its first week in Paris. The Vatican placed it on the Index of Forbidden Books in 1956. It has never been out of print since.
It is the opening sentence of Volume Two of The Second Sex. Beauvoir's claim is that womanhood is not something a person is born as but something a person is made into by a social apparatus — family, school, religion, marriage law, labour law, cultural expectation, sexual initiation — that begins in childhood and continues to old age. The sentence is the book's most quoted line and the seed of all subsequent constructivist accounts of gender in twentieth-century feminism.
The 2009 translation by Constance Borde and Sheila Malovany-Chevallier, published by Knopf. It is complete and translates Beauvoir's philosophical vocabulary rigorously. For fifty-six years — from 1953 to 2009 — the only English text available was H.M. Parshley's abridgment, which cut roughly fifteen per cent of the book (all of it argumentative content) and rendered Beauvoir's philosophy as general essayistic prose. Every anglophone feminist thinker from Betty Friedan onward read Parshley. Reading Borde and Malovany-Chevallier is closer to reading Beauvoir.
Two volumes, seven parts. Volume One (Facts and Myths): Part I Destiny (biology, psychoanalysis, historical materialism); Part II History (women from prehistory to the twentieth century); Part III Myths (a chapter each on Montherlant, D.H. Lawrence, Claudel, Breton, Stendhal, plus a chapter on the myth of the eternal feminine). Volume Two (Lived Experience): Part I Formation (childhood, the young girl, sexual initiation, the lesbian); Part II Situation (marriage, motherhood, social life, prostitution, aging); Part III Justifications (narcissism, love, mysticism); Part IV Toward Liberation (the independent woman and the Conclusion).

Every major argument in Anglophone feminist theory since 1949 has, at some point, extended, refined, or objected to something The Second Sex first put in place.
For its treatment of Catholic teaching on marriage and reproduction, its argument that the family had historically operated to subordinate women, and its chapters on sexuality — including the chapter on the lesbian, which was cited most frequently in the ecclesiastical objections. Le Deuxième sexe was placed on the Index Librorum Prohibitorum in 1956; the Index was itself abolished by Pope Paul VI in 1966.
