What is existentialism, really? A clear guide to the philosophy of existence — from Kierkegaard's leap of faith to Camus's absurd hero, and why it matters in the 21st century.
Few intellectual partnerships in history have been as influential, unconventional, and enduring as that between Jean-Paul Sartre and Simone de Beauvoir. Together, they dominated French existentialist philosophy in the mid-20th century, challenged social conventions, and produced works that continue to shape contemporary thought on freedom, authenticity, gender, and human existence. The Sartre Beauvoir philosophy partnership represents not just a meeting of minds but a radical experiment in living according to existentialist principles, creating a relationship that defied traditional boundaries while producing groundbreaking philosophical and literary achievements.

When Jean-Paul Sartre and Simone de Beauvoir met in 1929 as students at the prestigious École Normale Supérieure in Paris, they were both preparing for the agrégation, France's most competitive teaching examination. Sartre placed first, Beauvoir second—she was the youngest person ever to pass the philosophy agrégation at age 21. This intellectual equality set the tone for their entire relationship.
Their initial conversations revealed shared philosophical interests and a mutual rejection of bourgeois morality. Sartre, already developing the existentialist ideas that would make him famous, found in Beauvoir not merely a romantic partner but an intellectual equal capable of challenging, refining, and expanding his ideas. Beauvoir, for her part, discovered someone who took her philosophical ambitions seriously in an era when women philosophers were rare and often dismissed.
From the outset, they established an unconventional arrangement: a two-year renewable contract of companionship that prioritized intellectual and emotional honesty over traditional marriage vows. They agreed to maintain what they called an "essential" love while allowing for "contingent" affairs with others. This pact, which they largely maintained for over fifty years until Sartre's death in 1980, scandalized many but exemplified their commitment to existential freedom—the idea that individuals must define themselves through their choices rather than conforming to pre-established norms.
To understand the Sartre Beauvoir philosophy partnership, we must first grasp the core tenets of existentialism that both thinkers embraced and developed. Sartre's famous dictum "existence precedes essence" encapsulates this philosophy: humans are not born with a predetermined nature or purpose. Instead, we are "thrown" into existence and must create our own meaning through the choices we make and the actions we take.
This emphasis on radical freedom carried profound implications. If no external authority—neither God, nor tradition, nor social convention—can dictate who we must be, then we bear full responsibility for what we make of ourselves. Sartre termed this overwhelming burden of freedom "anguish," the anxiety that accompanies the realization that our choices define not only ourselves but also our values and, by extension, humanity itself.
Both Sartre and Beauvoir explored the concept of "bad faith"—the attempt to escape this burden of freedom by pretending we have no choice, that our actions are determined by our roles, circumstances, or nature. The waiter who over-identifies with his role as waiter, the woman who pretends she has no agency in a seduction—these examples from Sartre's "Being and Nothingness" (1943) illustrate how people flee from freedom into comforting but inauthentic modes of being.
Beauvoir's philosophical contributions, particularly in "The Ethics of Ambiguity" (1947), added crucial dimensions to existentialist thought. She emphasized that human freedom always exists in ambiguous situations where we are simultaneously free and constrained, subject and object, autonomous and dependent on others. True authenticity requires acknowledging this ambiguity rather than denying it.
While Sartre's "Being and Nothingness" remains existentialism's most systematic philosophical exposition, Beauvoir's "The Second Sex" (1949) represents perhaps the partnership's most revolutionary and enduring contribution. This groundbreaking feminist text applied existentialist philosophy to the situation of women, demonstrating how patriarchal society systematically denies women the freedom to define themselves.
Beauvoir's famous declaration—"One is not born, but rather becomes, a woman"—extended Sartre's existentialist insight to gender. Femininity, she argued, is not a biological destiny but a social construction imposed on female bodies. Society positions women as the "Other" to man's "Subject," as immanent objects rather than transcendent agents, denying them the freedom to create their own essence through free choice.
The book's exhaustive analysis covered history, biology, psychoanalysis, Marxism, literature, and contemporary women's lived experiences. Beauvoir demonstrated how every aspect of women's lives—from childhood education to marriage, motherhood, and old age—conspired to limit female freedom and confine women to passive, subordinate roles. Yet she also insisted that women must take responsibility for their complicity in this oppression, refusing to claim victimhood while demanding the right to full human freedom.
"The Second Sex" shocked and outraged many readers (including the Vatican, which placed it on its Index of forbidden books) but became foundational to second-wave feminism. Beauvoir's existentialist feminism insisted that women's liberation required not just political rights but a fundamental transformation of consciousness—a rejection of bad faith and a claim to authentic, self-defining freedom.
The Sartre Beauvoir philosophy never remained merely abstract theorizing. Both thinkers insisted that authentic existence requires political engagement—what Sartre called "commitment" (engagement). Intellectuals, they believed, had a responsibility to take sides in the struggles of their time.
During World War II, both participated in the French Resistance, though their roles were limited. After the war, they became increasingly politically active, particularly on the Left. Sartre's relationship with Marxism and communism was complex and troubled; he famously termed the Soviet Union's vast network of forced labor camps "inexcusable" yet continued to support various socialist causes while criticizing both American capitalism and Soviet authoritarianism.
Beauvoir threw herself into feminist activism, serving as president of the French League for Women's Rights and supporting movements for contraception, abortion rights, and women's economic independence. She signed the "Manifesto of the 343," declaring she had had an illegal abortion (a considerable risk) to support abortion rights in France.
Both opposed French colonialism, particularly the Algerian War. Sartre's support for Algerian independence made him a target; his apartment was bombed twice by right-wing extremists. These political commitments sometimes created tensions—Sartre's initial support for Stalin and reluctance to criticize Soviet oppression, for instance, troubled many who otherwise admired his work—but they reflected the existentialist conviction that freedom must be exercised through concrete action in the world.
The unconventional nature of Sartre and Beauvoir's relationship fascinated, inspired, and troubled observers for decades. They never married, never lived together, and maintained what they called a "transparent" policy of discussing their other romantic and sexual relationships with each other. This arrangement, while celebrated by some as a liberation from possessive monogamy, also had its costs.
Recent scholarship, particularly the publication of Beauvoir's letters and diaries, has complicated the heroic narrative of perfectly equal partners freely choosing their path. The "contingent" affairs sometimes caused real pain, particularly to Beauvoir. The power dynamics between them, while more equal than most relationships of their era, still reflected gendered expectations—Beauvoir often acted as Sartre's editor, advisor, and caretaker while he received more public recognition.
Yet their partnership endured for five decades, evolving as they aged. In later life, as Sartre's health declined, Beauvoir became his primary caregiver, demonstrating that their "essential" love, however unconventionally expressed, ran deep. When Sartre died in 1980, more than 50,000 people attended his funeral—but Beauvoir's grief was personal and profound. She lived six more years, publishing conversations with Sartre and reflecting on their shared life before her own death in 1986. They are buried side by side in Montparnasse Cemetery in Paris.
The Sartre Beauvoir philosophy continues to influence contemporary thought across multiple domains. Existentialism's emphasis on freedom, choice, and authenticity resonates with ongoing discussions about identity, meaning, and values in an increasingly secular, pluralistic world. Beauvoir's feminist existentialism remains central to gender studies, queer theory, and contemporary feminism.
Their insistence that intellectuals must be politically engaged has influenced generations of activist scholars. Their experiments in relationship structures anticipated contemporary discussions about ethical non-monogamy, relationship anarchy, and alternatives to traditional marriage. Their lives demonstrated—messily, imperfectly, but courageously—what it might mean to reject inherited scripts and write one's own.
Critics have pointed to limitations and contradictions in their work and lives: Sartre's sometimes problematic relationship with Soviet communism, Beauvoir's participation in relationships with younger women that today would raise serious ethical questions, the gap between their egalitarian ideals and some patriarchal patterns in their actual relationship. These critiques don't negate their contributions but remind us that even the most radical thinkers remain products of their time and circumstances.
The partnership between Jean-Paul Sartre and Simone de Beauvoir represents a remarkable experiment in living philosophically—in applying abstract ideas about freedom, authenticity, and commitment to the concrete circumstances of daily life. They didn't always succeed; their lives contained contradictions, pain, and failures alongside their achievements.
Yet the Sartre Beauvoir philosophy endures because it addresses permanent features of human existence: our freedom to choose who we become, our responsibility for those choices, our need for authentic connection with others, and our obligation to resist oppression and fight for liberation. Whether we accept or reject their specific conclusions, their insistence that we must think deeply about how to live—and then have the courage to live according to our conclusions—remains as relevant as ever.
In a world where social media, consumer culture, and political tribalism constantly tempt us into bad faith, where women still struggle for full equality, where the question "how should I live?" admits no easy answers, the existentialist insights of Sartre and Beauvoir continue to challenge and inspire. They remind us that we are, as Sartre wrote, "condemned to be free"—and that this condemnation is also our greatest possibility.
