Origins of existentialism
Existentialism is a philosophical movement centered on individual existence, freedom, and choice. It asks a question most other philosophies sidestep: if the universe doesn't hand you a purpose, how do you live?
The movement took shape across the 19th and 20th centuries, largely in response to societal upheavals that shook people's confidence in religion, reason, and progress. Earlier thinkers had questioned the nature of human existence and meaning, but existentialism pulled those threads together into something more urgent and personal.
Key historical influences
Several thinkers laid the groundwork before existentialism had a name:
- Søren Kierkegaard stressed subjective truth and individual responsibility. He argued that the most important questions in life can't be answered by abstract systems; they have to be lived through.
- Friedrich Nietzsche declared that God was "dead" as a source of shared meaning in Western culture. Without that foundation, he argued, individuals must create their own values.
- Edmund Husserl developed phenomenology, a method for carefully examining human consciousness and experience. This gave later existentialists a rigorous way to study how people actually encounter the world.
- Martin Heidegger built on Husserl's work with his concept of "Being-in-the-world," exploring how human existence is always embedded in a specific situation, not floating in the abstract.
Post-World War II context
World War II was a turning point. The sheer scale of destruction and atrocity made it hard to keep believing in steady human progress or a benevolent cosmic order. Existentialism surged in popularity because it spoke directly to that disillusionment.
Jean-Paul Sartre and Albert Camus became leading voices in post-war France, reaching wide audiences through both philosophical essays and novels. The Cold War and the threat of nuclear annihilation only deepened existentialist concerns: if everything could end in an instant, what grounds your choices?
Fundamental concepts
Existentialism focuses on the human condition and the individual's search for meaning in a universe that doesn't provide one. It rejects determinism and insists on radical human freedom, which sounds liberating until you realize it also means radical responsibility.
Existence precedes essence
This is the core claim of existentialism, especially as Sartre framed it. Traditional philosophy often assumed humans have a fixed nature or purpose (an "essence") built in from the start, whether by God or by biology. Existentialists flip that: you're born first, and then you define who you are through your choices and actions.
There's no blueprint. You aren't "meant" to be anything. That's both freeing and unsettling, because it means you can't blame your nature for your decisions.
Freedom and responsibility
Humans are fundamentally free to make choices and create their own meaning. But this freedom isn't a gift you can return. Sartre argued you cannot escape it. Even refusing to choose is itself a choice.
This inescapable freedom produces what existentialists call anguish: the weight of knowing that your decisions are entirely yours, with no cosmic safety net to catch you if you choose wrong.
Authenticity vs. bad faith
- Authenticity means living in line with your true self, accepting your freedom, and owning your choices.
- Bad faith is self-deception: pretending you have no choice, hiding behind social roles, or telling yourself "I had to do it" when you didn't.
People slip into bad faith because confronting total freedom is anxiety-inducing. Authenticity requires facing the uncertainty of existence head-on and choosing anyway.
Major existentialist thinkers
Existentialism isn't a single doctrine. It's more like a family of thinkers who share overlapping concerns but often disagree on specifics. Their work spans philosophy, literature, and psychology.
Søren Kierkegaard
The Danish philosopher often called the father of existentialism. Kierkegaard emphasized subjective truth and personal faith over abstract systems. He introduced concepts like anxiety (the dizziness of freedom), despair, and the "leap of faith", the idea that committing to belief requires jumping beyond what reason alone can justify.
Key works: Fear and Trembling, The Concept of Anxiety
Jean-Paul Sartre
The French philosopher and writer who did the most to popularize existentialism in the 20th century. Sartre developed the phrase "existence precedes essence" into a full philosophical framework and explored freedom, responsibility, and authenticity across both dense philosophical texts and accessible fiction and drama.
Key works: Being and Nothingness, the play No Exit (famous for the line "Hell is other people")
Simone de Beauvoir
A French existentialist philosopher, novelist, and feminist who applied existentialist ideas to gender and social structures. In The Second Sex (1949), she argued that women's oppression stems from being defined as "the Other" in relation to men. Women, she wrote, are not born into a fixed feminine nature; they are shaped into one by society. This directly extends the existentialist principle that existence precedes essence.
Key works: The Second Sex, The Ethics of Ambiguity
Existentialism in literature
Existentialist ideas found some of their most powerful expression not in philosophy papers but in fiction, drama, and essays. Literary works could show characters living through existential dilemmas rather than just theorizing about them.
Albert Camus
A French-Algerian writer and philosopher closely associated with existentialism, though he personally rejected the label. Camus focused on the absurd: the gap between humans' desire for meaning and the universe's silence. His concept of the "absurd hero" describes someone who keeps going despite recognizing life's meaninglessness. In The Myth of Sisyphus, he famously concludes that we must imagine Sisyphus happy, endlessly rolling his boulder uphill.
Key works: The Stranger, The Myth of Sisyphus, The Plague
Franz Kafka
A Czech writer whose work predates the existentialist movement but anticipates many of its themes. Kafka's characters face alienation, absurdity, and incomprehensible bureaucratic systems. In The Metamorphosis (1915), a man wakes up transformed into a giant insect, and the story focuses less on the bizarre event itself than on the social isolation and indifference that follow.
Key works: The Metamorphosis, The Trial, The Castle
Samuel Beckett
An Irish playwright and novelist associated with the Theatre of the Absurd. Beckett's works strip away plot and purpose to expose characters trapped in seemingly pointless routines. In Waiting for Godot (1953), two men wait endlessly for someone who never arrives, filling time with circular conversations. The play dramatizes existential themes of meaninglessness, repetition, and persistence without resolution.
Key works: Waiting for Godot; the novel trilogy Molloy, Malone Dies, and The Unnamable
Existentialist themes
Several recurring themes run through existentialist philosophy and literature. These aren't separate topics so much as different angles on the same central problem: what does it mean to exist as a free, conscious being in an indifferent world?
Absurdity of existence
The universe offers no built-in meaning or direction. Humans naturally seek purpose, but the world doesn't answer back. This collision between human need and cosmic silence is what Camus called the absurd. The existentialist response isn't to give up but to keep living and acting despite the lack of guarantees. Camus' Sisyphus, condemned to roll a boulder uphill forever, becomes the model: meaning comes from the struggle itself.
Anxiety and dread
Existential anxiety isn't ordinary worry about specific problems. It's a deeper unease that comes from confronting your own freedom and the unknown.
- Kierkegaard described angst as the dizziness you feel when you realize how many possibilities lie open before you.
- Sartre wrote about nausea, a visceral reaction to the sheer contingency of existence, the realization that things don't have to be any particular way.
- Heidegger explored being-towards-death: the awareness that you will die, and that this awareness shapes how you live.
Alienation and isolation
Existentialists frequently depict individuals feeling disconnected from others and from the world. This isn't just loneliness; it stems from recognizing that your inner experience is ultimately yours alone. You can never fully know another person's consciousness, and they can never fully know yours. Camus' Meursault in The Stranger and Sartre's Roquentin in Nausea both embody this sense of detachment.
Critique of traditional philosophy
Existentialism positions itself against much of the Western philosophical tradition. Where traditional philosophy often seeks universal truths through abstract reasoning, existentialism insists on starting from the concrete experience of the individual.
Rejection of systematic thinking
Existentialists argue that reality can't be fully captured by logical systems. Kierkegaard specifically targeted Hegel, whose philosophy tried to explain all of history and existence within one grand rational framework. Kierkegaard's objection: a system like that might be internally consistent, but it leaves out the one thing that matters most, the actual living, choosing, suffering individual. Reason has limits, and subjective experience can't be reduced to a formula.
Emphasis on individual experience
Rather than asking "What is the good life?" in the abstract, existentialists ask "What does this person face in this situation?" Sartre's concept of "situation" captures this: you always make choices from within a specific context, with specific constraints and possibilities. Universal ethical systems that claim to apply equally to everyone in every circumstance miss the messy reality of actual human decision-making.
Existentialism and religion
Existentialism has both atheistic and religious branches. This surprises some students, since the movement is often associated with godlessness. But the core questions (How do you find meaning? How do you live authentically?) can be explored with or without belief in God.
Atheistic existentialism
Sartre and Camus represent this strand. If there is no God, there is no pre-designed human nature and no cosmic source of meaning. Humans are entirely on their own. Sartre's "existence precedes essence" follows directly: without a creator, there's no blueprint. The challenge becomes building meaning and ethics from scratch, through your own choices.
Religious existentialism
Kierkegaard and Gabriel Marcel explored existential themes within a religious framework. For Kierkegaard, faith isn't a comfortable certainty; it's a "leap" made in the face of doubt and uncertainty. Believing in God requires going beyond what reason can prove, and that leap is itself an existential act. Paul Tillich later explored what he called "the courage to be," the willingness to affirm life and faith even while confronting existential anxiety and doubt.
Impact on modern thought
Existentialism's influence extends well beyond philosophy departments. Its ideas about freedom, meaning, and identity have shaped psychology, the arts, and everyday culture.
Influence on psychology
Existentialist philosophy gave rise to existential psychology and psychotherapy, which treat questions of meaning, mortality, and freedom as central to mental health rather than as distractions from it.
- Rollo May and Irvin Yalom developed therapeutic approaches that directly address existential concerns like isolation, death, and purposelessness.
- Viktor Frankl, a Holocaust survivor, created logotherapy, a form of therapy built on the idea that finding meaning in life is the primary human drive. His book Man's Search for Meaning remains widely read.
- Existential themes have also been incorporated into humanistic psychology and some forms of cognitive-behavioral therapy.
Existentialism in popular culture
Existentialist ideas have filtered into film, literature, and music, often reaching audiences who've never read Sartre or Camus.
- Directors like Ingmar Bergman (The Seventh Seal) and Woody Allen explore themes of mortality, meaning, and alienation.
- Contemporary novelists like Haruki Murakami and Milan Kundera engage with existential questions about identity and freedom.
- Punk and post-punk music (The Cure, Joy Division) often channels existential themes of alienation and despair.
Key existentialist works
These texts are among the most influential in the movement and are still widely assigned in philosophy and literature courses.
Being and Nothingness
Sartre's 1943 philosophical treatise, often considered the central text of existentialist philosophy. It explores consciousness, freedom, and the nature of human existence. Sartre introduces key ideas here, including bad faith and the distinction between being-for-itself (conscious, self-aware existence) and being-in-itself (the non-conscious existence of objects). It's a dense, challenging read, but it's where Sartre lays out his full philosophical system.
The Stranger
Camus' 1942 novel, a compact and readable work that dramatizes his philosophy of the absurd. The protagonist, Meursault, is an emotionally detached man living in Algeria who commits a senseless murder and faces trial. The novel is less about the crime than about Meursault's refusal to perform the emotions society expects of him. It challenges readers to consider what happens when someone simply stops pretending life has built-in meaning.
Fear and Trembling
Kierkegaard's 1843 work examining the biblical story of Abraham's willingness to sacrifice his son Isaac. Kierkegaard uses this story to explore the tension between ethical duty and religious faith. He introduces the idea of a "teleological suspension of the ethical": the possibility that faith might demand something that goes beyond, or even against, universal moral rules. The "knight of faith" is his term for someone who makes that leap.
Criticisms of existentialism
No philosophical movement goes unchallenged, and existentialism has drawn significant criticism from multiple directions.
Nihilism accusations
Critics worry that rejecting inherent meaning opens the door to nihilism, the belief that nothing matters at all. If there are no objective values, what stops someone from concluding that morality is pointless? Existentialists push back on this: they argue that creating your own meaning is the opposite of nihilism. The whole point is to choose values and commit to them, not to abandon them.
Limitations of individual focus
The emphasis on individual experience has drawn fire from several camps:
- Marxist thinkers argue that existentialism ignores how social and economic structures shape what choices are actually available to people. Freedom means something different if you're wealthy versus impoverished.
- Feminist philosophers have pointed out that much existentialist writing reflects a male-centered perspective (though de Beauvoir is a notable exception).
- Some critics argue that the focus on individual choice downplays the importance of community, solidarity, and collective responsibility.
These are real limitations. Existentialism offers powerful tools for thinking about personal freedom and meaning, but it doesn't always account for the social conditions that constrain or enable that freedom.
