It’s been over seventy-five years since The Second Sex hit the shelves in France, and honestly, the world still hasn't quite caught up to it. When Simone de Beauvoir first published this massive, two-volume beast of a book in 1949, it didn't just ruffle feathers. It caused a literal scandal. People were outraged. The Vatican even put it on their list of prohibited books. Think about that for a second. A philosophy book was considered so dangerous to the status quo that the Church told people they’d be risking their souls just by reading it.
Why? Because Beauvoir dared to say out loud what most women felt but couldn't name: that "woman" isn't a fixed biological destiny, but a social construct.
The Sentence That Changed Everything
You’ve probably heard the most famous line from the book: "One is not born, but rather becomes, a woman."
It sounds simple, right? But it’s the foundation of almost all modern gender theory. Beauvoir was an existentialist. She believed that humans are defined by their actions and their freedom to choose who they are. But she noticed a glaring problem. Men were allowed to just "be" human—the default, the subject, the absolute. Women, however, were always defined in relation to men. They were the "Other."
The Problem of the "Other"
In The Second Sex, Beauvoir spends hundreds of pages digging through biology, history, and mythology to prove that there is no "eternal feminine" essence.
Men are the "Subject." Women are the "Object."
Imagine you're at a party and someone asks what you do. If you're a man, you just answer. If you're a woman, in Beauvoir's time (and often still today), your identity was filtered through your role as a wife, a mother, or a daughter. You were the "Other" because your existence was validated by someone else’s perspective. This isn't just some abstract philosophy. It’s the reason why, for centuries, women were kept out of the workforce, denied the vote, and told their highest calling was domesticity.
Beauvoir argues that this isn't natural. It’s a trap.
Why It’s Actually Hard to Read
Let’s be real: The Second Sex is a slog in some places. It’s dense. Beauvoir was a brilliant academic, and she writes like one. She goes on these long tangents about the reproductive systems of insects and the history of bronze-age agriculture. You might find yourself wondering why you're reading about the mating habits of dragonflies when you just wanted to learn about feminism.
But there’s a method to the madness. She wanted to dismantle every single argument used to keep women "in their place."
She starts with biology. She admits that women have different physical experiences—menstruation, pregnancy, menopause—but she argues fiercely that these biological facts don't justify a secondary social status. A body is not a destiny. From there, she moves to history, showing how the rise of private property led to the "world-historical defeat of the female sex," as Friedrich Engels put it.
The Myth of the "Happy Housewife"
Long before Betty Friedan wrote The Feminine Mystique, Beauvoir was tearing down the idea that women find ultimate fulfillment in housework. She described the repetitive nature of domestic chores as a "Sisyphean" task. You clean the floor, it gets dirty. You cook the meal, it gets eaten. There is no "transcendence" in it. It doesn't build anything for the future; it just maintains the present.
For Beauvoir, a meaningful life requires transcendence—reaching out into the world to create, to change things, and to project oneself into the future. By confining women to the "immanence" of the home, society was effectively stifling their humanity.
The Controversies and the Critics
It’s worth noting that Beauvoir isn't a perfect hero by today’s standards. Her work has been criticized for being "Eurocentric" and for largely ignoring the experiences of women of color or working-class women who didn't have the luxury of existential angst because they were too busy surviving.
Some modern critics also point out that she seems a bit dismissive of motherhood. She saw it as a potential trap that drains a woman’s autonomy. While many women today find deep meaning in being parents, Beauvoir was writing in a context where motherhood was often the only choice. She wanted to make sure it was a choice, not a mandate.
Does it still matter in 2026?
You might think, "Hey, we have female CEOs and world leaders now. Isn't this book a relic?"
Not exactly.
The "Othering" Beauvoir talked about has just changed shape. We see it in the "pink tax," where products marketed to women cost more. We see it in the way female celebrities are scrutinized for their aging in a way men never are. We see it in the internal struggle many women feel trying to "have it all"—a struggle that stems from the lingering expectation that their primary role is still domestic, even if they have a career.

The Second Sex is a mirror. It asks us: How much of your personality is actually you, and how much is a performance of what society expects your gender to be?
How to Actually Tackle the Book
If you're going to read it, don't feel guilty about skipping the biology chapter. Seriously. Start with the "Proem" or the "Myths" section. It’s where the juice is.
- Look for the 2009 translation. The original 1953 English translation by H.M. Parshley was... let's just say, not great. Parshley was a zoologist, not a philosopher, and he cut out about 15% of the original text, including many of the names of women philosophers Beauvoir referenced. The newer translation by Constance Borde and Sheila Malovany-Chevallier is much more faithful to her actual voice.
- Read it in chunks. This isn't a beach read. It’s a "sit in a coffee shop with a highlighter" read.
- Join a discussion group. Beauvoir’s ideas are best chewed on with others. Her relationship with Jean-Paul Sartre, her own complicated personal life, and her political activism provide endless context for what she wrote.
Actionable Takeaways
Reading The Second Sex isn't just an academic exercise. It’s a toolkit for self-awareness.
First, start noticing the "Subject/Object" dynamic in your daily life. When you’re in a meeting, who is taking up space and who is reacting? When you watch a movie, is the female lead a person with her own goals, or is she just there to help the male lead reach his?
Second, challenge the idea of "natural" roles. Next time someone says, "Women are just naturally better at [insert chore here]," remember Beauvoir. Most "natural" things are actually just habits we’ve been practicing for a few thousand years.
Finally, prioritize your own "transcendence." Find the things that allow you to project yourself into the world—hobbies, careers, or projects that aren't about serving someone else, but about expressing your own freedom. Beauvoir’s ultimate goal wasn't just to complain about oppression; it was to clear the path for every individual to define themselves on their own terms.
Take a look at your own life. Identify one area where you’ve been acting as the "Other"—waiting for permission or defining yourself through someone else’s eyes. Make a conscious choice this week to act as the "Subject" in that area instead. Whether it's voicing a difficult opinion or starting a project you’ve put off, reclaim your status as the primary narrator of your own story.
