Start with The Ethics of Ambiguity
The Second Sex is the famous one and it's 800 pages. The Ethics of Ambiguity (1947) is 160, and it does something Sartre never managed: it derives an actual ethics from existentialist premises.
If nothing is given and we're radically free, how are you supposed to act? Her answer turns on the freedom of others: your freedom is meaningless unless other people are also free, so willing your own freedom commits you to willing theirs. That's the argument Sartre kept promising and never delivered.
| Book | Year | What it is |
|---|---|---|
| The Ethics of Ambiguity | 1947 | Existentialist ethics, 160 pages. The best first book. |
| The Second Sex | 1949 | The foundational text of modern feminist theory. Long, and worth it. |
| Memoirs of a Dutiful Daughter | 1958 | First volume of the memoirs, on a bourgeois Catholic girlhood she escaped. |
| The Mandarins | 1954 | Novel. Won the Goncourt. Post-war Paris intellectuals, thinly disguised. |
| A Very Easy Death | 1964 | Her mother's death, over 100 pages. Devastating and precise. |
| The Coming of Age | 1970 | On old age. Neglected, and arguably her most original book after The Second Sex. |
Which translation of The Second Sex
This matters more than it usually does. The 1953 English translation by H.M. Parshley, a zoologist with limited French, cut roughly 15% of the text and mistranslated the philosophical vocabulary throughout, flattening the existentialist argument into something closer to sociology.
That was the only English version for 56 years. The 2009 translation by Constance Borde and Sheila Malovany-Chevallier is complete. Buy that one, and check the copyright page if you're picking up a secondhand copy.
"One is not born, but rather becomes, a woman"
The most quoted line, and it's making a philosophical claim rather than a slogan. Womanhood, on her account, is a situation produced by upbringing, expectation and constraint, rather than an essence that arrives with a body.
Her other central concept is the Other. Man is positioned as the default human and woman as the deviation from it, defined relative to him. Once you see that structure, she argues, you see it operating everywhere, and much of the book is patient documentation of it across biology, history, myth and lived experience.
Around her
Sartre, her partner for fifty years, in a relationship whose actual conduct has been reassessed critically and unfavourably in recent decades. Hannah Arendt, a contemporary who disliked her. Existentialism for beginners for the wider movement.
365 Days of Philosophy covers her within the year, alongside the tradition she was arguing with.
Common questions
Which Simone de Beauvoir book should I read first?
The Ethics of Ambiguity (1947). At 160 pages it's far more approachable than The Second Sex, and it delivers the existentialist ethics Sartre never wrote.
Which translation of The Second Sex is best?
The 2009 Borde and Malovany-Chevallier translation, which is complete. The 1953 Parshley version cut about 15% and mistranslated the philosophical terms, and it was the only English edition for 56 years.
What does 'one is not born, but rather becomes, a woman' mean?
That womanhood is a situation produced by upbringing, expectation and constraint rather than an essence delivered with a body. It's a philosophical claim, not a slogan.
Was Beauvoir just following Sartre?
That was the standard view for decades and it's been substantially revised. The Ethics of Ambiguity solves a problem Sartre left open, and The Second Sex has no equivalent in his work.
Is The Second Sex still worth reading?
Yes, though it's long and parts of the science are dated. The structural argument about woman as the Other has aged remarkably well.
