Existentialism is a loosely defined philosophy that encouraged authentic living

Many writers considered 'existentialist' didn't identify with the term

“Existentialism” was first introduced in 1943 by philosopher Gabriel Marcel. Jean-Paul Sartre and Simone de Beauvoir readily adopted the term, but others, such as Albert Camus and Martin Heidegger, rejected it. Earlier philosophers, like Søren Kierkegaard and Friedrich Nietzsche, were long dead by the time the word was in vogue.

Existentialist literature explores the philosophy's ideas

Existentialism isn't confined to philosophical texts. Some of the movement's figureheads, like Albert Camus and Jean-Paul Sartre, were also novelists. Christina Howells, Professor of French at the University of Oxford, suggests this is because existentialism, as a philosophy, requires human stories to be fully understood, and literature makes the experience of the human condition more present and immediate.

Existentialism inspired Franklin Roosevelt and Martin Luther King Jr.

The Danish philosopher, sometimes called “the father of existentialism,” believed that individuals needed to resist the temptation of conformity and instead discover their authentic selves. His work became remarkably influential in the 20th century. In 1944, Roosevelt said that reading Kierkegaard made him understand how the Nazis could’ve enacted so much violence. In 1959, King wrote that existentialism was “especially meaningful for our time.”

Existentialism has been used as a therapeutic tool, with 2 Swiss psychiatrists pioneering the philosophy's concepts to help patients navigate their issues.

Jean-Paul Sartre believed 'existence precedes essence'

The existentialist figurehead argued that humans are not born with an identity or purpose; instead, they develop them throughout their lives. For Sartre, this meant making meaning for oneself rather than relying on authorities (like religion or government) to provide it.

An existentialist reading list

If you’re looking for a starting point for diving into existentialist thought, this is a great resource. Its titles are not exactly obscure—Albert Camus’ “The Stranger,” Franz Kafka’s “The Trial,” and Søren Kierkegaard’s “Either/Or” are among the most famous works in Western literature—but the list provides some digestible context for each text, which will help you decide the best place to begin your journey.

Scholars trace existential anxiety back to early Hebrew scriptures

Paul Megna, a scholar of literature and philosophy, notes that the existentialist ideas of Kierkegaard (and, to a lesser extent, Sarte and Camus) had their roots in much earlier texts, which posited that "fear of the Lord" was "the beginning of wisdom."

Sartre believed those who deny their own freedom are operating in 'bad faith'

In "Existentialism is a Humanism," Sartre argues that humans are "condemned to be free"—they are not confined to a divine fate, which means they must take the responsibility of creating their own destinies. Those who reject this freedom, by his estimation, are living in "bad faith."

One teacher's lesson on existentialism and social media use

During a unit on existentialist literature and philosophy, one teacher at Massachusetts’ Phillips Academy asked students to surrender their cell phones to test Kierkegaard’s thoughts on the danger of conformity and Sartre’s belief that humans are “condemned to be free.” Many of them were surprised to find how liberated they felt once they left behind social media.

What is transcendentalism?

The 19th-century movement, largely centered around the ideas of Ralph Waldo Emerson, believed that individuals needed to form transcendent connections with the universe. For many transcendentalist philosophers, writers, and religious figures, that meant seeking it in nature. This Stanford explainer on the philosophy digs deep into its major concepts and figureheads.

Existential dread still informs popular comedies

Although the Theater of the Absurd was primarily a 20th-century trend, a similar kind of existentialist-minded comedy still exists in popular culture. Films like “Everything Everywhere All At Once” and television shows like “BoJack Horseman” tackle the same issues that existentialist thinkers like Sartre, Beauvoir, and Camus explored, transforming those profound questions into thought-provoking and crowd-pleasing works of comedy.

Disillusioned mid-century playwrights, such as Samuel Beckett and Eugène Ionesco, brought existentialist ideas to the stage through the Theater of the Absurd.

Kierkegaard used pseudonyms throughout his writing

“The Father of Existentialism” published over 40 texts and 40 articles during his life and used several pen names throughout them. The pseudonyms allowed him to present relevant opinions in a relatable, first-person manner without the reader believing that Søren Kierkegaard earnestly held them.

Friedrich Nietzsche theorized that we will live our lives over and over again: the myth of eternal recurrence

Rather than a theory of physics, the idea is designed as a moral argument. While Nietzsche famously eschewed the Christian afterlife, he wanted to avoid the nihilism that results from no longer having such an ultimate horizon. In a mystical moment, the philosopher came to believe that the fleeting moments of our lives would be repeated, presenting a test: would you want to relive this moment? If not, he would argue, you're not living well.

Novelist Richard Wright joined the existentialists in Paris

The author of “Black Boy” and “Native Son” left the United States in 1946 to escape his home country’s racial inequality. In Paris, he explored existentialist ideas and spent time with Simone de Beauvoir and Jean-Paul Sartre. “The Outsider,” a novel he wrote while living in France, embraced many of the philosophy’s central themes.

Heavy metal legends Black Sabbath touched on existentialist themes

Although they’re primarily known for Ozzy Osbourne’s distinctive singing and Tony Iommi’s singular riffs, the metal icons Black Sabbath also have a body of work that explores existentialist questions about mankind’s purpose. Philosophy professor William Irwin unpacks the band's lyrics and applies them to some of existentialism’s major themes, drawing comparisons between the band and philosophers like Friedrich Nietzsche, Jean-Paul Sartre, and Albert Camus.

Simone de Beauvoir's 'The Second Sex' merged existentialism with feminism

De Beauvoir’s 1949 philosophical treatise criticized patriarchy and its negative impact on women. She argued that gender differences were mainly due to socialization rather than innate qualities, writing that “one is not born, but rather becomes, a woman.” In turn, de Beauvoir believed women should refuse predetermined gender roles and instead define themselves, echoing a key tenet of existentialism.

Sartre and de Beauvoir had an open romantic relationship

The two figureheads of existentialist thought were romantic partners, though they had a publicly open relationship and never lived together. As de Beauvoir says in the interview below, "third persons knew our relationship dwarfed any we could have with them."

Albert Camus believed existence was 'absurd'

He didn't use "absurd" as we often do—meaning something silly—but instead to describe humans' desire to ascribe meaning and transcendence in a world that provided neither. Camus believed we needed to acknowledge and accept this absurdity rather than hopelessly believing we'd one day overcome it.

Sartre admired American novelist William Faulkner

In addition to writing philosophy and fiction, Jean-Paul Sartre was also a literary critic. His 1939 essay on Faulkner's "The Sound and the Fury" focused on the way the American novelist commented on time, favorably comparing him to Marcel Proust. Ultimately, Sartre argues Faulkner's "despair" about a "closed future" is a result of the "social conditions of our present life." Ever the existentialist, though, Sartre suggests this reality is something that should inspire rather than depress.

Camus and Sartre admired each other's work before becoming friends

The two writers, who would later be considered two of the biggest names associated with existentialism, wrote positive reviews of each others' early work, with Camus praising Sartre's novel "Nausea" and story collection "The Wall" and, later, Sartre favorably compared Camus' "The Stranger" to Franz Kafka and Ernest Hemingway. Still, their reviews included some critiques, hinting at the larger disagreements that would come much later.

Albert Camus' 'The Fall' encourages readers to live without illusions

The writer's final complete novel is a series of dramatic monologues from Jean-Baptiste Clamence, who tries to explain to a stranger the sound of laughter that began following him. As the "Philosophize This!" podcast argues, the book is Camus' attempt at wrestling with some of the thornier aspects of existentialism in a form that's more digestible than a dense philosophical tome.

Read Albert Camus' 'Myth of Sisyphus and Other Essays'

Camus' most famous work of nonfiction is this collection of philosophical essays. Perhaps the most resonant entry is the title essay, which reimagines the Greek myth of a man condemned to roll a boulder for all eternity. Rather than presenting the story as a cautionary tale about defying the gods, as the original myth intended, Camus considered Sisyphus an "absurd hero" for his actions and imagined him smiling as he endlessly toiled at his repetitive punishment.

The Beat Generation, explained

The Beat Generation challenged societal norms in the 1950s by embracing experimental writing and tackling taboo topics like drug use, spirituality, and nonconformity. Figures like Allen Ginsberg, Jack Kerouac, and Diane di Prima sparked a cultural movement that rejected traditional literary forms and explored the hidden struggles of American life.

The Beats autobiographical impulse is still influential

The Beats autobiographical approach to literature is seen in contemporary autofiction. While autofiction emerged as a literary term in the 1970s, its philosophy has several antecedents, including Colette’s Claudine novels, Marcel Proust’s "In Search of Lost Time" and Beat writer Jack Kerouac’s "On the Road."

Defiance is choosing to act in line with your values under pressure

Compliance often arises from insinuation anxiety and social pressure, making defiance critical in protecting personal integrity and, in turn, strengthening institutions. Practicing defiance may be achieved through the Defiance Compass framework and can lead to a more values-driven society.

Jean-Paul Sartre worked on 'Being and Nothingness' while a prisoner of war

The Nazis invaded France in May 1940. Sartre, as a member of the French Army, was taken prisoner that June. While he was in captivity, he studied Martin Heidegger and worked on "Being and Nothingness," one of his most famous philosophical works.

One of Sartre and de Beauvoir's lovers accused them of exploitation

Samuel Beckett's 'Waiting for Godot' dramatizes existential absurdity

The play, originally staged in 1953, is notorious for its lack of action. For the most part, its two principal characters, Vladimir and Estragon, spend the majority of the play wondering whether a mysterious Godot will ever appear. By the end, Godot has still not arrived, yet Vladimir and Estragon do not move, a choice that reflects the existential notion that humans often hope in vain for meaning that does not exist.

What was the beef between Romanticism and the Enlightenment?

Would you embrace logic or lead with emotion? In the 18th century, Romanticism challenged the Enlightenment’s focus on reason, arguing that imagination, nature, and intuition held deeper truths. From literature to art, this movement reshaped culture—sparking a debate between order and passion.

Why some writers believe there's a new romanticism

Journalist and novelist Ross Barkan argues that a crushing political system and alienating technology have led people to become more interested in the offline, analog world and the beauty of nature and emotion. In this essay, he defines this as "the new romanticism," and predicts it will come to define the culture of the 2020s.

Ben Franklin’s edit helped define the Declaration’s philosophy

When Thomas Jefferson drafted the Declaration, he wrote that its truths were “sacred and undeniable.” Benjamin Franklin urged replacing that phrase with “self-evident,” grounding the document in reason rather than religious authority and sharpening its Enlightenment logic.

Socrates, who never wrote down his ideas, is considered by many the father of Western philosophy.

Basquiat's work is often called neoexpressionist

The neoexpressionist movement was a reaction to the minimalism of the 1960s, employing bold colors and brash symbolism to convey emotion and, at times, make political statements. As the style’s name implies, it was a new form of expressionism, a movement popular in the early 20th century.

'The Stranger' remains a popular novel for teenagers

Camus' book's themes—alienation, transgression, and existentialism—continue to resonate with adolescent reader. That's also true of other popular teenage touchstones, like Aldous Huxley's "Brave New World," George Orwell's "Nineteen Eighty-Four," and Sylvia Plath's "The Bell Jar," which are still widely read—and assigned by high school teachers.

Candide's 'Voltaire' satirized blind optimism

The French philosopher's most famous work, published in 1759, cataloged the journey of its titular hero, who was guided by a crackpot philosopher and the belief that optimism was the solution to life's problems, despite all the evidence to the contrary.

Romanticism challenged neoclassicalism

Neoclassical artists believed in the promise of the Enlightenment—that logic was a cure-all for society’s problems—and sought to apply a similar rationality to their artwork. That meant straightforward, realistic work that portrayed historical scenes as close to real life as possible without any visible evidence of the artist’s handiwork.
