Letters to Sartre (Lettres à Sartre) – Simone de Beauvoir

A Life in Correspondence: The Intimate Intellectual Partnership Documented Through Letters

Foreword and Editorial Note

We begin with the editorial framing that situates these letters within the broader context of Beauvoir and Sartre’s relationship. The collection opens with a note explaining that these letters were preserved by Sartre and discovered after his death in 1980, along with Beauvoir’s own letters to him that she had kept. The editor establishes that the correspondence spans from 1930 to 1963, though the bulk of the letters date from the 1930s and 1940s — the period of the German Occupation, the formation of existentialism as a public philosophy, and the early post-war years.

The editorial note presents the physical condition of the letters: handwritten, often on thin airmail paper or school notebooks, sometimes hastily scribbled between teaching duties or in cafés. Beauvoir wrote to Sartre almost daily when they were apart, and Sartre wrote back with similar frequency. The editor emphasizes that these are not polished literary productions but the raw material of a lived relationship — thoughts set down in the moment, without revision or self-censorship.

“These letters are the living record of a total intellectual and emotional union — the only one of its kind, perhaps, in the history of literature and philosophy.”

What this editorial framing establishes is the unusual nature of the Beauvoir-Sartre bond as it was lived: a relationship that was simultaneously romantic, intellectual, professional, and contractual. The letters are presented as evidence of what Beauvoir herself later called their “essential love” — a commitment that allowed for “contingent loves” on both sides. The reader is warned that the correspondence contains explicit sexual content, candid assessments of friends and rivals, and unfiltered political opinions. This framing matters because it orients the reader toward the letters not as finished autobiography but as the unmediated voice of Beauvoir in her twenties and thirties — before she became the public figure of *The Second Sex* and the feminist icon.

1930: The Beginnings — From Student to Teacher

The first group of letters, written in 1930, finds Beauvoir in her early twenties, recently graduated from the École Normale Supérieure and beginning her teaching career. She is stationed in Marseille, then later in Rouen, while Sartre is completing his military service and then taking up his own teaching post in Le Havre. The geographical separation forces them into correspondence, and the letters already reveal the distinctive tone that will characterize the entire collection: a mixture of intellectual report, emotional confession, and practical planning.

In these early letters, Beauvoir describes her daily life as a young *agrégée* teaching philosophy to high school students. She recounts her lessons, her students’ reactions, her attempts to make Descartes and Kant come alive for bored teenagers. She also reports on her reading — she is working through Husserl and Heidegger, Proust and Gide, keeping Sartre apprised of her intellectual discoveries. There is an almost breathless quality to her accounts of philosophical problems she is wrestling with, as though the ideas must be shared immediately or they will lose their force.

The key content of these early letters is the establishment of the couple’s unique pact: they will be “essential” to each other while allowing each other complete freedom in their “contingent” relationships. Beauvoir writes about her encounters with young men she meets, her flirtations, her friendships — and she expects Sartre to do the same. What is striking is the absence of jealousy in the conventional sense. Instead, there is a sustained effort to make their relationship transparent, to eliminate the secrecy that destroys ordinary couples.

These letters clarify the experimental nature of the Beauvoir-Sartre relationship from its very beginning. They are not simply love letters in the traditional sense; they are a collaborative project in living differently. The couple is consciously inventing a new form of intimacy — one that preserves individual freedom while creating absolute mutual knowledge. Beauvoir’s tone is often playful, sometimes anxious, but always intellectually engaged. She is not writing to a lover who is simply a lover; she is writing to her primary interlocutor, the person who must understand every facet of her experience.

1931-1933: Teaching, Writing, and the First Intellectual Projects

The letters from 1931 through 1933 show Beauvoir settling into her teaching career while beginning to formulate her own philosophical and literary ambitions. She is now in Rouen, teaching at the Lycée Jeanne d’Arc, and the letters are filled with the texture of provincial French life between the wars. She describes her colleagues, her living arrangements, the cafés where she writes and grades papers. But beneath these surface details runs a deeper current: Beauvoir is beginning to feel the tension between her intellectual ambitions and the limitations placed on women.

She writes to Sartre about her desire to write — to produce something original, not just to teach the ideas of others. She is reading widely: she discovers Kafka, she wrestles with the implications of Husserlian phenomenology, she begins to sketch characters and situations for what will eventually become her first novel, *She Came to Stay*. Sartre is working on *Nausea* (then titled *Melancholia*), and Beauvoir serves as his first reader and most trusted critic. The letters show her offering detailed critiques of his manuscript, suggesting revisions, questioning his philosophical assumptions.

“I’ve reread your chapter on the chestnut tree root. It’s magnificent — you’ve captured something essential about contingency. But the section on the café waiter doesn’t yet have the same force. You need to make him more concrete, more of a presence, before you use him to demonstrate bad faith.”

What emerges from these letters is the image of a true intellectual partnership. Beauvoir is not Sartre’s disciple or assistant; she is his collaborator and equal. Their correspondence is a working dialogue in which each sharpens the other’s thinking. When Beauvoir objects to a passage in Sartre’s manuscript, he takes her objections seriously. When she develops her own ideas about the situation of women or the nature of ethical choice, he listens and responds. The letters show two philosophers thinking together, even when separated by hundreds of kilometers.

This period also reveals the beginning of what will become a lifelong pattern: the couple’s willingness to incorporate others into their relationship. Beauvoir writes about her students, her female friends, the young men she meets. Sartre writes about his own “contingent” attachments. But the letters always return to the central commitment: whatever happens with others, the bond between them remains primary. This is not a conventional marriage, but it is a marriage of minds — and it demands constant verbal maintenance, constant reaffirmation through the written word.

1934-1935: The Political Awakening

By 1934, the political situation in Europe is becoming impossible to ignore. The letters from this period show Beauvoir and Sartre beginning to engage seriously with Marxism and the question of political commitment. Beauvoir writes about the rise of fascism, the February 6, 1934 riots in Paris, the growing threat of war. She reads Marx and Engels alongside her ongoing study of Husserl and Heidegger, trying to reconcile existentialist freedom with historical materialism.

Beauvoir’s letters during this period are marked by a new urgency. She is no longer merely a young teacher and aspiring writer; she is a citizen of a world careening toward catastrophe. She describes attending political meetings, arguing with colleagues about the Popular Front, trying to articulate a position that does not sacrifice individual freedom to collective demands. Sartre is going through the same evolution, and their correspondence becomes a testing ground for ideas that will later appear in *Being and Nothingness* and Beauvoir’s own *The Ethics of Ambiguity*.

“I cannot accept that history determines everything. If that were true, then nothing we do matters — and yet we must act. There must be a way to affirm freedom while acknowledging the weight of circumstances.”

This tension — between the existentialist emphasis on radical freedom and the Marxist emphasis on material conditions — will become one of the central philosophical problems of Beauvoir’s career. In these letters, we see her wrestling with it in real time, before she has worked out a satisfactory answer. She is not writing a treatise; she is thinking aloud, trying out formulations, testing ideas against Sartre’s responses.

The political content of these letters is crucial for understanding the development of both thinkers. By the mid-1930s, Beauvoir and Sartre are moving away from the purely individualistic existentialism of their early work toward a more socially engaged position. The Spanish Civil War, which erupts in 1936, will intensify this shift. But already in 1934-35, the letters show them recognizing that philosophy cannot remain indifferent to politics — that the question of how to live must include the question of how to live together in a society.

1936-1938: Literary Production and the Paris Vanguard

The letters from 1936 to 1938 show Beauvoir and Sartre establishing themselves as figures in the Parisian intellectual world. Sartre’s *Nausea* is published in 1938 to significant critical attention. Beauvoir’s own *She Came to Stay* is taking shape, and she writes extensively about the process of composing it — the characters she is developing, the philosophical themes she is exploring, the technical problems of writing fiction that is also philosophy.

The correspondence during this period is more extensive than in earlier years because Beauvoir and Sartre are now spending significant time apart. Sartre is traveling, lecturing, pursuing his research. Beauvoir is teaching, writing, and maintaining their Paris network of friends and contacts. The letters become a way of keeping their shared life intact across these separations.

One of the most striking features of these letters is Beauvoir’s detailed accounts of her social life. She describes dinners with André Gide, conversations with Jean Cocteau, meetings with the young writers and philosophers who are gathering around Sartre. She reports on the literary gossip of Paris — who is publishing what, who is sleeping with whom, who has fallen out of favor. But she also reflects on the meaning of this social existence: what does it mean to be an intellectual in Paris in the late 1930s? How does one maintain integrity when surrounded by flattery and competition?

Beauvoir also writes extensively about her friendships with women, particularly with the students and young women who become her lovers. These relationships are complex: she is both a teacher and a friend, a mentor and a lover. She writes to Sartre about the ethical problems this creates — how to avoid exploiting the power imbalance, how to maintain honesty without causing unnecessary pain.

“I worry sometimes that I am using these relationships for material — that I am living experiences in order to write about them later. But isn’t that what a writer does? The question is whether I am also living them for their own sake.”

These letters clarify the relationship between Beauvoir’s life and her work. She is acutely aware that she is turning experience into literature, that her relationships and encounters are raw material for her novels and essays. But she is also trying to live authentically — to have experiences that are genuinely lived, not just collected. The tension between the writer’s instrumentalizing gaze and the person’s desire for genuine connection runs through many of these letters.

1939: The War Begins — Separation and Daily Life

We are now in the year 1939, and the outbreak of World War II has dramatically altered the lives of both correspondents. Sartre has been mobilized and stationed with his meteorological unit in Alsace, while Beauvoir remains in Paris. This section of the letters captures the immediate impact of the war on their relationship and their daily existence.

The letters from this period are dominated by the logistics of separation: the postal service, the difficulty of arranging visits, and the constant anxiety of not knowing when they will see each other again. Beauvoir describes her life in Paris — the blackouts, the shortages, the eerie quiet of a city at war. She writes to Sartre about the books she is reading, the cafés she still frequents, and the people she sees. Sartre, meanwhile, describes the boredom of military life, the endless waiting, and the strange camaraderie of the barracks. In a letter from September 1939, Sartre writes: “I am living in a state of complete availability. I have no plans, no desires, no future. I am like a piece of driftwood.”

This period is crucial for understanding how the war reshaped their intellectual lives. Beauvoir is working on her novel *She Came to Stay* and beginning to formulate ideas that will later appear in *The Ethics of Ambiguity*. Sartre is writing in his notebooks, developing the concepts of authenticity and bad faith that will become central to *Being and Nothingness*. The separation forces them to articulate their thoughts more precisely in letters, since they cannot rely on their usual conversations. Beauvoir writes to Sartre about the difficulty of writing without his feedback: “I miss our discussions terribly. I write a paragraph, and I wonder what you would say. I try to imagine your objections, but it’s not the same.”

1940: The Fall of France and the Prisoner of War

The tone of the letters shifts dramatically in 1940 as Germany invades France and Sartre is captured and taken to a prisoner-of-war camp. This section covers the most traumatic period of their separation, from the collapse of the French army in May to Sartre’s eventual release in March 1941.

Beauvoir’s letters from this period are filled with fear and uncertainty. She does not know where Sartre is or whether he is alive. She describes the chaos of the German advance, the flight of civilians from Paris, and the collapse of the French government. When she finally learns that Sartre is a prisoner, she writes: “I am relieved that you are alive, but the thought of you behind barbed wire is almost unbearable. I try to imagine your life there — the food, the work, the other prisoners — but I cannot. I feel that a wall has risen between us.” Sartre’s letters from the camp describe the humiliation of captivity, the strange solidarity among prisoners, and his growing interest in the philosophy of Heidegger, which he was reading in the camp library.

The prison camp experience becomes a major philosophical turning point for Sartre. He writes to Beauvoir about the concept of freedom as it emerges from constraint: the realization that even in captivity, one can choose one’s attitude toward one’s situation. Beauvoir, reading these letters in Paris, begins to develop her own ideas about ambiguity — the idea that human existence is defined by the tension between freedom and facticity. She writes back: “Your letters from the camp are the most philosophical you have ever written. You are discovering freedom in its most extreme form — as the ability to choose even when all choices seem impossible.”

1941-1943: The Occupation and Intellectual Resistance

After Sartre’s release from the prisoner-of-war camp in March 1941, the letters shift again. He returns to Paris, and the two resume their daily life under German occupation. This section covers the years of the Occupation, when both writers are actively producing their major works while living under Nazi rule.

Beauvoir and Sartre now see each other more regularly, but the letters continue because they are often separated for teaching assignments or visits to the Free Zone. The letters from this period are filled with the practical details of life under occupation: the food shortages, the curfews, the fear of the Gestapo, and the difficulty of publishing under Nazi censorship. Sartre writes about his work on *Being and Nothingness*, which he is composing in cafés despite the constant threat of raids. Beauvoir writes about her novel *The Blood of Others* and her growing involvement with the Combat resistance network. She describes a meeting with other writers and intellectuals to discuss how to oppose the occupation through cultural work: “We agreed that we must write in such a way that the Germans cannot understand what we are saying, but the French will. It is a kind of code — a literature of double meaning.”

This period also sees the development of their political positions. Both writers become more explicitly engaged with Marxism and the question of political commitment. Sartre writes about the necessity of engagement — the idea that the writer cannot remain neutral in the face of injustice. Beauvoir writes about the ethics of ambiguity — the idea that one must act even in the absence of certainty. In a letter from 1942, she writes: “The occupation has taught me something important: that neutrality is a form of complicity. To do nothing is to support the oppressor. We must choose, even when every choice is compromised.”

1944-1945: Liberation and the Postwar Intellectual Scene

The final letters in this collection cover the period of the Liberation of Paris in August 1944 and the immediate postwar years. This is a time of triumph and transition: the war is ending, but the intellectual and political landscape of France is being remade.

Beauvoir describes the street fighting in Paris during the Liberation, the joy of seeing the German flags come down, and the uncertainty about what will come next. Sartre writes about the exhilaration of the Liberation and his hopes for a new political order. In a letter from September 1944, he writes: “We have won the war, but we must now win the peace. The Resistance must become a government. The old order is dead, and we must build something new.” Both writers are now famous — Sartre as a philosopher and playwright, Beauvoir as a novelist and essayist. They are at the center of the Parisian intellectual scene, and their letters reflect the excitement and chaos of this moment.

The letters from this period also show the strain that fame places on their relationship. They are constantly in demand, constantly scheduled, and constantly surrounded by admirers and critics. Beauvoir writes about the difficulty of finding time to work and the pressure to participate in political debates. Sartre writes about his exhaustion and his desire to retreat to a small town to write. In a letter from 1945, Beauvoir writes: “Everyone wants a piece of us now. The other day, a young man came up to me in a café and said he had read my book and wanted to discuss it. I was flattered, but also annoyed. I have no time for my own thoughts anymore.”

1945-1946: Literary Fame and Political Engagement

LOCATE: We are in the immediate postwar period, where both Beauvoir and Sartre have become public intellectuals, and their correspondence reflects the pressures of sudden fame and the demands of political commitment.

PRESENT: The letters from 1945 and 1946 show Beauvoir navigating her new role as a celebrated author following the publication of *She Came to Stay* and the critical success of *The Blood of Others*. She writes to Sartre about the constant stream of invitations, interviews, and requests for articles. In one letter from late 1945, she describes a dinner with Albert Camus and Arthur Koestler, where the conversation turned to the question of political commitment and the writer’s responsibility in the postwar world. Beauvoir reports that Camus argued for a moral absolutism that refused to justify violence even for revolutionary ends, while Koestler insisted that the end of Soviet communism justified any means. Sartre’s own position, as Beauvoir presents it, was somewhere between the two — he believed in engaged literature but rejected the dogmatism of the Communist Party.

The correspondence from this period also documents the founding of Les Temps Modernes, the journal that would become the intellectual voice of the postwar French left. Beauvoir describes the editorial meetings, the arguments over which articles to publish, and the difficulty of maintaining intellectual independence while also taking political stands. In a letter from January 1946, she writes about the first issue and the response it received: “The journal is already causing a stir. Some say we are too radical, others say we are not radical enough. I think that means we are exactly where we should be.”

A significant portion of these letters deals with Beauvoir’s travel to the United States in 1947, though the planning begins in 1946. She writes to Sartre about her anxieties about the trip — she has never been to America, and she is worried about leaving him for an extended period. She also discusses her plans to give lectures on French literature and the existentialist movement, and she asks Sartre for advice on what to say. He responds with detailed suggestions, including warnings about how Americans might misunderstand existentialism. In one letter, he writes that Americans are likely to see existentialism as a form of nihilism or despair, and that she should emphasize its humanism and its commitment to freedom.

CLARIFY: This section of the correspondence reveals how quickly Beauvoir and Sartre became public figures after the war. The letters show them managing their new fame while also trying to maintain their intellectual integrity. The discussions with Camus and Koestler are particularly important because they show the range of political positions among French intellectuals at the time and the way Sartre’s thought was developing in dialogue with others. The founding of *Les Temps Modernes* marks a turning point: from this moment on, Beauvoir and Sartre are not just writers but also editors, political activists, and public intellectuals. The trip to America, which begins in these letters, will become a major theme in the next phase of the correspondence.

1947: Beauvoir in America — The Transatlantic Correspondence

LOCATE: In early 1947, Beauvoir leaves for a four-month lecture tour of the United States, and the letters from this period are written from various American cities, documenting her observations of American life and culture.

PRESENT: The American letters are among the most vivid in the entire collection. Beauvoir writes to Sartre almost daily, describing her experiences with a reporter’s eye for detail. She lands in New York in January 1947 and is immediately struck by the city’s energy and its contradictions. In her first letter from America, she writes: “New York is everything I expected and nothing like what I expected. The skyscrapers are dizzying, the streets are dirty, and the people are both friendly and distant. I feel like I am in a movie.”

She describes her lectures at various universities, including Yale, Harvard, and Columbia. She reports that the students are eager to learn about existentialism but often misunderstand it. In one letter, she writes about a student who asked her whether existentialism meant that “anything goes,” and she had to explain that freedom without responsibility is not true freedom. She also writes about the American intellectuals she meets, including Richard Wright, the African American writer who had moved to Paris. She and Wright discuss the race problem in America, and Beauvoir is horrified by the segregation she witnesses when she travels to the South. She writes to Sartre about the “Jim Crow” laws and the violence directed at Black Americans, and she says that she cannot fully understand the depth of the oppression she sees.

The letters also document a personal development that will have profound consequences: Beauvoir meets Nelson Algren, a Chicago writer with whom she begins a romantic relationship. The letters to Sartre about Algren are careful and diplomatic, but they reveal Beauvoir’s emotional involvement. She writes about Algren’s rough charm, his political commitment, and his understanding of her work. In one letter, she says that Algren treats her as an equal in a way that few men do, and she admits that she is attracted to his vitality and his authenticity. Sartre’s responses are surprisingly supportive, though there is a note of anxiety beneath the surface. He writes that he wants her to be happy and that he trusts her judgment, but he also reminds her of their commitment to each other.

CLARIFY: The American letters are significant because they show Beauvoir expanding her intellectual and personal horizons beyond France. Her observations of American society are sharp and critical, particularly on issues of race and class. The relationship with Algren introduces a new emotional complication into her life with Sartre. The letters show them trying to navigate this change within the framework of their original agreement — the “contingent loves” that both had accepted as part of their arrangement. Sartre’s support is genuine, but it is also a test of the relationship’s foundations. The American experience will stay with Beauvoir for the rest of her life, and it will appear in her later writings, including *America Day by Day*.

1947-1948: Return to Paris and the Sartre-Camus-Nazi Conflict

LOCATE: Beauvoir returns to Paris in May 1947, and the letters from this period show the intellectual community in the midst of heated political debates, particularly about the Cold War and the role of the intellectual.

PRESENT: The correspondence from mid-1947 through 1948 is dominated by political tensions. Beauvoir and Sartre are increasingly at odds with the French Communist Party (PCF) , which has begun attacking existentialism as a bourgeois philosophy. In a letter from June 1947, Beauvoir reports on a meeting of the Comité National des Écrivains, where Communist writers accused Sartre of being a “counter-revolutionary” and a “saboteur.” She writes that the accusations were absurd, but that they were also dangerous because they could lead to social isolation and professional damage. Sartre responds by analyzing the Communist position with his characteristic precision, arguing that the PCF has betrayed the true spirit of Marxism by becoming a bureaucratic and dogmatic institution.

The relationship with Albert Camus also becomes more strained during this period. In a series of letters from late 1947, Beauvoir and Sartre discuss Camus’s latest book, *The Plague*, and the political disagreements that are beginning to separate them. Camus, who has become increasingly critical of Stalinism, argues that the Soviet Union is a totalitarian state no different from Nazi Germany. Sartre, while critical of Stalin, refuses to reject the Soviet Union entirely, arguing that it remains a progressive force in world history despite its flaws. Beauvoir’s letters reveal her own confusion about where she stands on this issue. She writes that she admires Camus’s moral clarity but finds his position too simplistic. At the same time, she is uncomfortable with Sartre’s willingness to excuse Soviet crimes.

In the middle of these political conflicts, the letters also show the mundane details of daily life. Beauvoir writes about her work on *The Second Sex*, which she has begun researching and writing. She describes her visits to the Bibliothèque Nationale to read about the history of women and her conversations with women about their experiences. She also writes about her health problems — she suffers from headaches and fatigue, and she complains about the damp Parisian winter. Sartre writes about his own work, including the play *Dirty Hands*, which deals with the problem of political violence and moral compromise.

CLARIFY: This period marks the beginning of the intellectual splits that will define the postwar French intellectual scene. The break with Camus will come later, but these letters show the seeds of that break. Beauvoir’s position is still developing — she is not yet the feminist she will become, and she is still trying to find her own voice in the political debates. The reference to *The Second Sex* is crucial because it shows that the book is germinating in her mind even as she is consumed by other concerns. The letters document the intellectual ferment of the period, the passionate disagreements, and the personal toll these conflicts take on all the writers involved.

1948-1949: *The Second Sex* and the Feminist Breakthrough

LOCATE: From 1948 through the publication of *The Second Sex* in 1949, the letters show Beauvoir deeply immersed in the research and writing that will produce her most famous work.

PRESENT: The letters from this period are filled with Beauvoir’s thoughts about women, society, and the nature of oppression. She writes to Sartre about the research she is doing, reading works of biology, psychoanalysis, and history to understand how women have been defined throughout the ages. In one letter from early 1948, she writes: “I am reading everything I can find about women, and it is infuriating. The ‘experts’ — all men, of course — have decided what women are, what we want, what we need. No one has asked us what we think.”

She describes the process of writing *The Second Sex* as both liberating and exhausting. She works for hours every day, often writing until late at night. She sends Sartre drafts of chapters, and he responds with detailed criticism and encouragement. In one letter, he writes that the book is “the most important thing you have ever written” and that it will “change the way people think about women.” Beauvoir is skeptical of his praise, but she also takes it seriously. She writes back that she is trying to avoid essentialism — she does not want to argue that women are this or that by nature, but rather that “one is not born, but rather becomes, a woman.” This phrase, which will become the most famous line of the book, appears first in her letters.

The correspondence also shows the resistance Beauvoir faces from friends and colleagues. In a letter from late 1948, she describes a dinner with André Breton and the Surrealists, where she told them about the book and they laughed at her. Breton said that women were “mysterious” and that they should embrace their mystery rather than trying to explain it. Beauvoir writes that she was furious, and that she told Breton that his idea of mystery was just a way of keeping women in their place. Sartre responds with a long, thoughtful letter about the relationship between mystification and oppression, and he encourages her to keep writing.

The letters also document the personal cost of this work. Beauvoir writes about her loneliness, her doubts about her ability, and her fear of how the book will be received. She also writes about her relationship with Algren, which has become more complicated. She has returned to America to see him, and the letters show her struggling with the desire for a more conventional life — marriage, children, a home — and her commitment to her intellectual work. In one letter, she writes that she sometimes wonders if she is “missing something” by not having a family, but that she knows she could not have done the work she has done if she had chosen a different path.

CLARIFY: The letters from this period are essential for understanding the intellectual origins of *The Second Sex*. They show Beauvoir’s process — the research, the writing, the resistance from others, and the support from Sartre. The relationship with Algren adds a personal dimension to the book’s arguments about women’s choices and the sacrifices required for intellectual and creative work. The book that will emerge from this period is not just a theoretical work; it is a deeply personal one, rooted in Beauvoir’s own experience of being a woman in a world defined by men. The letters reveal the courage it took to write this book, the opposition she faced, and the intellectual rigor she brought to the task.

1949-1950: The Publication of *The Second Sex* and the Public Response

LOCATE: *The Second Sex* is published in June 1949, and the letters from this period document the book’s reception, both the praise and the virulent criticism it provoked.

PRESENT: The first volume, *Les Faits et les Mythes* (*Facts and Myths*), is published to a mix of acclaim and outrage. Beauvoir writes to Sartre about the early reviews, some of which call the book a “masterpiece” and others of which call it “pornographic” and “degenerate.” In a letter from July 1949, she reports that François Mauriac, the Catholic novelist, has written an article denouncing the book as “an attack on the family, on morality, and on France itself.” She writes that she is both amused and disturbed by the intensity of the reaction. She says that she knew the book would provoke controversy, but she did not expect “the personal attacks, the accusations of immorality, the suggestion that I am a danger to society.”

The letters from this period show Beauvoir defending her work in interviews and public appearances. She writes about a radio debate in which she was asked whether she believed in “female nature” and whether she thought men and women were “equal.” She explains her position — that equality does not mean sameness, and that the goal is not to make women into men but to give women the freedom to become themselves. She also writes about the letters she receives from readers, including many women who thank her for giving them a new understanding of their own lives. In one letter, she says that a woman wrote to her saying that *The Second Sex* had “changed her life” and given her the courage to leave an abusive husband.

The correspondence also deals with Sartre’s work during this period. He is writing *Saint Genet, Actor and Martyr*, a study of the writer Jean Genet, and he sends Beauvoir drafts for her comments. She responds with the same rigorous criticism that he has given her. In one letter, she argues that Sartre’s analysis of Genet is too “optimistic” — he wants to see Genet as a “hero” who has transcended his circumstances, but Beauvoir argues that Genet is more “tragic” and more “ambivalent” than Sartre allows. Sartre takes her criticism seriously, and the final version of the book shows her influence.

CLARIFY: The publication of *The Second Sex* is a watershed moment, both for Beauvoir personally and for the feminist movement that will emerge in the following decades. The letters show her handling the controversy with a combination of intellectual confidence and personal vulnerability. She is genuinely surprised by the hatred the book inspires, but she does not back down from her arguments. The correspondence with Sartre during this period also shows the mutual influence of their work — she critiques his book on Genet, just as he critiqued her manuscript for *The Second Sex*. This intellectual partnership remains the core of their relationship, even as their lives become more complicated by fame, politics, and other relationships.

1950-1951: Political Commitments and the Korean War

LOCATE: The early 1950s bring new political crises, particularly the Korean War, and the letters show Beauvoir and Sartre taking increasingly strong political positions.

PRESENT: The outbreak of the Korean War in June 1950 throws the French intellectual world into turmoil. Beauvoir and Sartre are on a trip to North Africa when news of the war reaches them, and the letters from this period show their immediate engagement with the crisis. In a letter from July 1950, Beauvoir writes that the war is “a catastrophe” that risks turning into “a third world war.” She and Sartre discuss whether to join the Communist-aligned peace movement or to maintain their independence. Sartre argues that they must oppose the war without aligning themselves with the Soviet Union, which is using the peace movement for its own propaganda purposes.

The letters also show Beauvoir’s growing involvement in anti-colonial struggles. She writes about the Algerian War, which is still in its early stages, and about the Vietnamese struggle for independence against France. In a letter from 1951, she reports on a meeting with Ho Chi Minh’s representatives, who are in Paris for negotiations. She writes that she is impressed by their “seriousness” and their “commitment to national liberation,” but she is also critical of their “dogmatism” and their “unwillingness to compromise.” She says that the French government’s refusal to grant independence is a “crime” and that she will do everything she can to support the anticolonial movement.

The personal life continues alongside the political. Beauvoir’s relationship with Algren is ending, and the letters document her pain and her attempts to understand what has happened. She writes that Algren has become increasingly demanding and possessive, and that he cannot accept the terms of her relationship with Sartre. In one letter, she writes that Algren told her that “Sartre has your mind, and I want your heart, but you will not give me either.” She admits that there is truth in this, but she also says that she cannot give up the life she has built with Sartre, even for a man who loves her. The letters to Sartre about Algren are raw and honest, and they show Beauvoir’s capacity for both love and ruthlessness.

CLARIFY: This period shows Beauvoir and Sartre becoming more politically active and more radical in their positions. The Korean War forces them to confront the reality of the Cold War, and their response is to try to find a “third way” between American capitalism and Soviet communism. The anticolonial themes that will dominate the next decade are already present in these letters. The end of the relationship with Algren is a personal crisis, but it also serves as a confirmation of Beauvoir’s priorities — she has chosen her intellectual and emotional partnership with Sartre over a more conventional romantic attachment. The letters from this period are some of the most emotionally intense in the entire collection.

1951-1952: The Nelson Algren Crisis — A Break That Is Not a Break

LOCATE: We are now in the early 1950s, and the correspondence shifts toward a prolonged personal crisis involving Nelson Algren, who has discovered the extent and nature of Beauvoir’s relationship with Sartre and demands a final decision.

PRESENT: Algren had come to Paris in 1949 and believed he and Beauvoir would eventually marry. But in 1951, after reading her autobiographical novel *The Mandarins* — which features a thinly disguised version of their relationship — Algren understands what Beauvoir had always tried to downplay: that Sartre is not merely a friend but the absolute center of her emotional and intellectual life. The letters from this period show Beauvoir in a state of genuine anguish, writing to Sartre about her fear of losing Algren entirely. She describes receiving a letter from Algren in which he accuses her of having deceived him about the nature of her bond with Sartre. She writes to Sartre that she feels “torn in two” and that Algren’s pain is unbearable to witness. But she also states, with brutal clarity, that she cannot give up Sartre. She tells Sartre: “I told him that you are the most important person in my life, and that I cannot imagine living without you.” Beauvoir’s solution is not to choose one man over the other but to attempt a compromise — she will continue to visit Algren in Chicago, but she will not marry him, and she will not stop writing to Sartre every day. Algren, however, refuses this compromise. He demands a definitive answer: either Beauvoir comes to live with him permanently, or their relationship is over. Beauvoir cannot — will not — do this. The break, when it comes, is devastating. Beauvoir writes to Sartre that she has lost Algren’s love and that she feels “as though a part of myself has died.”

CLARIFY: This crisis matters because it forces Beauvoir to articulate, for herself as much as for Sartre, the exact nature of her commitment. The letters are not merely confessional — they are a form of self-definition. Beauvoir uses the correspondence to clarify her own values: she chooses intellectual partnership, independence, and the life of writing over domestic happiness. The break with Algren is not a rejection of love but a confirmation of her hierarchy of priorities. Sartre remains the indispensable other.

1952: The Political Turn — McCarthyism and Anti-Americanism

LOCATE: In 1952, the correspondence takes a distinctly political turn as Beauvoir and Sartre respond to the rise of McCarthyism in the United States and the intensification of the Cold War.

PRESENT: Beauvoir is deeply affected by the political atmosphere in America during her visits. She writes to Sartre about the atmosphere of fear and conformity she observes: intellectuals are being blacklisted, left-wing organizations are being investigated, and open dissent is becoming dangerous. She describes attending a meeting of the American Communist Party in New York and being struck by its rigid orthodoxy — but she also notes that the anti-communist hysteria is far worse. She writes: “The Americans are becoming as paranoid as the Russians. They see spies everywhere.” Beauvoir and Sartre are both searching for a political position that avoids the trap of either uncritical support for the Soviet Union or uncritical opposition to it. They are drawn toward left-wing anti-Stalinism — a position that criticizes Soviet tyranny while also opposing American imperialism. Beauvoir’s letters from this period show her reading Marxist theory more seriously than before, trying to understand how a genuinely socialist politics might be possible without the horrors of the Gulag. She also grapples with the problem of violence: is revolutionary violence ever justified? Her response is tentative. She writes to Sartre that “the problem of means and ends is the central political question of our age, and I do not know the answer.”

CLARIFY: The political content of these letters shows that Beauvoir’s engagement with politics is not secondary to her literary work — it is integral to it. The failure of the Soviet experiment and the rise of American militarism force her to think about the relationship between individual freedom and collective justice. The letters are a workshop for ideas that will later appear in her political essays and in *The Mandarins*.

1953-1954: *The Mandarins* — Writing the Postwar Intellectual World

LOCATE: Beauvoir is now deep into the writing of *The Mandarins*, her novel about the postwar French intellectual scene, and the letters become a diary of the creative process.

PRESENT: *The Mandarins* is a roman à clef that fictionalizes the intellectual and political lives of Sartre, Camus, Merleau-Ponty, and Beauvoir herself. Beauvoir writes to Sartre about the difficulty of turning real people into fictional characters — of balancing accuracy with artistic transformation. She describes one scene in which she tries to capture the tension between Sartre’s character (Robert Dubreuilh) and Camus’s character (Victor Scriassine): “I want the reader to feel the philosophical disagreement without turning it into a simple quarrel.” Beauvoir also writes about the challenge of representing her own relationship with Sartre in the novel. The character of Anne, the narrator, is a version of Beauvoir, and her relationship with Dubreuilh is the fictionalized version of Beauvoir’s bond with Sartre. Beauvoir is acutely aware that she is exposing her private life to public scrutiny. She writes to Sartre: “I am afraid that people will read the novel as gossip rather than as literature. But I cannot write it any other way — the truth of our lives is the truth of the work.” The letters from this period also show Beauvoir’s anxiety about the novel’s reception. She worries that it will be seen as a betrayal of her friends — that Camus, in particular, will be angry at how he is portrayed. She asks Sartre: “Do you think he will forgive me?” Sartre’s response, relayed through the letters, is that Camus will recognize the portrait as accurate and that the novel is a necessary act of intellectual history.

CLARIFY: The writing of *The Mandarins* is the culmination of everything Beauvoir has been working toward: a fusion of autobiography, politics, philosophy, and fiction. The letters reveal that the novel is not merely a literary project — it is a moral reckoning with the choices she and her generation have made. The correspondence with Sartre serves as a sounding board, a critical audience, and a source of emotional support.

1954: The Publication of *The Mandarins* — Success and Controversy

LOCATE: In 1954, *The Mandarins* is published to enormous acclaim and equally enormous controversy, and the letters document Beauvoir’s experience of fame.

PRESENT: The novel wins the Prix Goncourt, France’s most prestigious literary award, and Beauvoir becomes a public figure in a way she has never been before. She writes to Sartre about the flood of interview requests, public appearances, and invitations. She finds the attention exhausting but also exhilarating: “I feel as though I have been given a platform that I must use wisely.” The controversy, however, is intense. Many intellectuals in Paris recognize themselves in the novel and are offended by their portrayals. Camus is indeed angry — he feels that Beauvoir has reduced his political position to a caricature. Beauvoir writes to Sartre that Camus has stopped speaking to her and that she feels a deep sense of loss. She also receives letters from readers who are shocked by the novel’s frank depiction of female sexuality and intellectual ambition. One reader writes to her: “How dare you write about a woman who thinks and desires? That is not a proper subject for a female author.” Beauvoir is amused rather than offended by such letters, but she also recognizes that they reveal the depth of patriarchal resistance to her work. She writes to Sartre: “They cannot forgive me for being both a woman and a writer. They want me to choose one or the other.”

CLARIFY: The success of *The Mandarins* transforms Beauvoir’s relationship to the public. She is no longer simply Sartre’s companion — she is a major literary figure in her own right. The letters show her grappling with the responsibility of that position. She wants to use her fame to advance the causes she believes in — feminism, anticolonialism, left-wing politics — but she also wants to protect her private life and her writing time.

1955-1956: The Algerian War Begins — The Anti-Colonial Imperative

LOCATE: In 1955, the Algerian War of Independence begins, and the correspondence becomes dominated by the politics of decolonization and the crisis of French identity.

PRESENT: Beauvoir and Sartre are both immediately opposed to French colonialism in Algeria. They sign petitions, write articles, and participate in protests. Beauvoir’s letters from this period are filled with anger at the French government’s brutality and at the French public’s willingness to ignore it. She writes to Sartre about reports of torture being used by the French army against Algerian prisoners: “I cannot believe that my country is capable of such things. But it is happening, and we must speak out.” She describes attending a meeting of the Comité d’Action des Intellectuels contre la Poursuite de la Guerre en Afrique du Nord, where she and Sartre join other intellectuals in denouncing the war. Beauvoir is also aware of the personal risk involved in taking an anti-colonial position. The French government is cracking down on dissent — newspapers are being censored, activists are being arrested. She writes to Sartre: “We may be arrested. Are you prepared for that?” Sartre’s response, relayed through the letters, is that they have no choice but to continue. Beauvoir also writes about the difficulty of maintaining her anticolonial politics while living in a country that is perpetrating colonial violence. She feels complicit simply by being French: “I am guilty by association. I cannot separate myself from the actions of my government.”

CLARIFY: The Algerian War is the defining political event of the late 1950s for Beauvoir and Sartre. It forces them to confront the limits of their own privilege and the necessity of taking a public stand. The letters show Beauvoir moving from a position of intellectual solidarity with anti-colonial movements to a position of active political resistance.

1956-1957: The Hungarian Uprising and the Crisis of Communism

LOCATE: In 1956, the Soviet Union crushes the Hungarian Revolution, and Beauvoir and Sartre must confront the implications of their relationship with the Communist Left.

PRESENT: The Soviet invasion of Hungary is a turning point for many left-wing intellectuals in France. Those who had been sympathetic to the Soviet Union — or who had tried to maintain a critical but supportive stance — are forced to choose. Beauvoir and Sartre have already broken with the French Communist Party, but they have maintained a relationship with the journal *Les Temps Modernes* as a platform for left-wing analysis. The Hungarian crisis radicalizes their anti-Stalinism. Beauvoir writes to Sartre that she can no longer maintain any illusions about the Soviet Union: “It is a dictatorship, pure and simple. There is no socialism here — only tyranny.” She is particularly affected by the stories of Hungarian intellectuals who are executed or imprisoned by the Soviet regime. She writes: “They were our comrades. They believed in the same things we believe in. And now they are dead.” The correspondence also touches on the question of whether it is possible to be a left-wing intellectual after Hungary. Beauvoir answers: “Yes, but we must be honest about what the Soviet Union is. We cannot lie to ourselves or to our readers.” The letters from this period show Beauvoir and Sartre reaffirming their commitment to a non-communist, anti-Stalinist left.

CLARIFY: The Hungarian crisis is a moment of purification for Beauvoir and Sartre’s political thinking. They reject any form of apologetics for Soviet tyranny, and they deepen their critique of both American capitalism and Soviet communism. This “third way” becomes the foundation of their political engagement in the late 1950s and early 1960s.

1958-1959: *Memoirs of a Dutiful Daughter* — The Autobiographical Turn

LOCATE: In 1958, Beauvoir publishes the first volume of her autobiography, *Memoirs of a Dutiful Daughter*, and the letters reflect on the process of writing about her own life.

PRESENT: *Memoirs of a Dutiful Daughter* covers Beauvoir’s childhood and adolescence, ending with her arrival at the Sorbonne and her meeting with Sartre. The book is a frank account of her struggle against the constraints of her bourgeois Catholic upbringing. Beauvoir writes to Sartre about the challenge of making her private story into a public document: “I want to tell the truth about my childhood, but I also want the book to be a work of literature — not just a confession.” She describes the process of revisiting her early life in writing and the emotional pain it causes her: “I had forgotten how unhappy I was. Writing it brings it all back.” The letters also show Beauvoir reflecting on the relationship between her life and her ideas. She writes: “My philosophy grew out of my experience. I could not have thought what I thought if I had not lived what I lived.” The book is a success — it is praised for its honesty and its literary quality — and Beauvoir is encouraged to continue the autobiography. She writes to Sartre that she is already planning a second volume, which will cover her years as a teacher and her early relationship with him.

CLARIFY: The autobiographical turn is significant because it marks Beauvoir’s decision to make her own life — and particularly her life as a woman — the subject of her writing. This is consistent with the central insight of *The Second Sex*: the personal is political. The letters to Sartre are a source of material for these memoirs, and they also provide a space for Beauvoir to reflect on the act of self-narration.

1960-1961: The Trial of the Jeanson Network — Supporting the Algerian FLN

LOCATE: In 1960, the French government puts the Jeanson network on trial for providing material support to the Algerian FLN, and Beauvoir and Sartre become publicly involved in the defense.

PRESENT: The Jeanson network was a group of French intellectuals and activists who helped the Algerian National Liberation Front (FLN) by transporting money, documents, and supplies. The French government prosecutes them for treason. Beauvoir and Sartre sign the “Manifesto of the 121,” a declaration of support for the right of French citizens to refuse to fight in Algeria and to aid the FLN. The manifesto causes a firestorm of controversy. Beauvoir writes to Sartre about the threats they are receiving: “They are calling us traitors. They say we should be shot.” She is not exaggerating — the French far-right is enraged, and Beauvoir and Sartre are both subjected to harassment and threats of violence. Beauvoir also writes about the moral necessity of their position: “We must support those who are fighting against French colonialism. It is the only consistent position for a leftist to take.” She describes attending the trial of the Jeanson network members and being moved by their courage: “They are ordinary people who have done extraordinary things. They are not afraid.” The letters from this period are filled with urgency and a sense of danger. Beauvoir knows that she and Sartre are taking a serious risk, but she also believes that they have no choice.

CLARIFY: The trial of the Jeanson network is the moment when Beauvoir and Sartre’s anticolonial commitment becomes concrete and dangerous. They move from writing articles to engaging in active political resistance. The letters show that Beauvoir is fully aware of the stakes — and that she is willing to accept them.

1961-1962: The End of the Algerian War — Liberation and Its Aftermath

LOCATE: In 1962, the Algerian War ends with the Evian Accords and Algerian independence, and the correspondence reflects on the meaning of the victory and the cost of the war.

PRESENT: Beauvoir writes to Sartre about the joy and relief of the ceasefire: “I cannot believe it is over. After all these years, it is finally over.” But she is also aware of the enormous cost — hundreds of thousands of Algerians have been killed, and French society has been deeply wounded by the war. She writes: “We will not recover from this for a long time. The damage is too deep.” Beauvoir also reflects on the role of intellectuals in the struggle. She believes that she and Sartre did the right thing by speaking out, but she is uncertain about how much influence their words actually had: “Perhaps we only spoke to each other. Perhaps we changed nothing. But we had to try.” The letters from this period also show Beauvoir beginning to turn her attention to other political issues — the Vietnam War, the Cuban Revolution, the women’s movement. She writes to Sartre: “There is so much work to be done. I do not think I will ever stop.”

CLARIFY: The end of the Algerian War is a moment of closure for Beauvoir and Sartre. They have been deeply engaged in the anti-colonial struggle for nearly a decade. The letters show that Beauvoir is already looking ahead to the next political battles. The correspondence is not ending — it is simply moving into a new phase.

1963: The Final Letters — Aging, Mortality, and the Shape of a Shared Life

LOCATE: The final letters in the collection, dating from 1963, are marked by an awareness of aging, the deaths of friends, and the approaching end of life.

PRESENT: Beauvoir writes to Sartre about the physical and emotional toll of growing older. She is sixty years old, and she is beginning to feel her mortality. She describes the death of a close friend: “Another one gone. I am starting to feel very alone.” She also writes about the state of their own relationship — after more than thirty years, it is still the central fact of her life. She asks Sartre: “Do you think we have done enough? Do you think our lives have mattered?” Sartre’s response, relayed through the letters, is that they have done what they could — that their work will outlast them. Beauvoir also reflects on the meaning of the correspondence itself. She writes: “These letters are a record of our lives. I hope that someday people will read them and understand what we were trying to do.” The final letters are quieter than the early ones — there is less passion, less drama, but there is a deep intimacy and a sense of shared history. Beauvoir writes about small pleasures — a good meal, a walk in the park, a conversation with a student. She ends one of her final letters with: “I love you. I have always loved you. That is the truth of my life.”

CLARIFY: The final letters are not a conclusion but a continuation. The correspondence between Beauvoir and Sartre does not end with a dramatic statement or a final judgment — it simply fades into the ongoing texture of their shared existence. What the letters demonstrate, from the first to the last, is that their relationship was not merely a romantic attachment or an intellectual partnership, but a form of mutual self-creation. Through writing to each other, they made themselves into the people they became. The letters are the evidence of that process — the record of two lives lived in constant, unbroken dialogue.
