Type: Philosophical Movement
Origin: 19th Century Europe (Kierkegaard, Nietzsche), popularized 1940s France
Also known as: Existential Philosophy, Philosophy of Existence
Quick Answer — Existentialism is a philosophical movement exploring how individuals can live authentic, meaningful lives in a universe that appears indifferent or meaningless. Emerging from 19th-century roots in Kierkegaard and Nietzsche and flourishing in postwar France through Sartre and Camus, it emphasizes individual freedom, responsibility, and the necessity of creating one’s own meaning in an apparently absurd existence.

​
What is Existentialism?

Existentialism begins with a premise that is both simple and unsettling: human beings exist first, and only afterward do they define themselves through their choices and actions. There is no predetermined essence—no grand cosmic script laying out what you should become or how you should live. You simply exist, and then you must decide who you are.
“Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.” — Jean-Paul Sartre, Existentialism is a Humanism (1945)
This freedom is exhilarating and terrifying in equal measure. Because there is no predetermined purpose, you are entirely responsible for creating your own meaning. No one else can live your life for you, and no external authority can provide ready-made answers to the fundamental questions of existence. The anxiety this produces—what existentialists call “angst”—is not a flaw in the system but the natural response to genuine freedom.

Existentialism in 3 Depths

  • Beginner: You feel overwhelmed by life’s big questions—What should I do with my life? Is there meaning somewhere? Existentialism says these feelings are not problems to be solved but signs that you are confronting the reality of your freedom. The discomfort comes from recognizing that no one else can answer these questions for you.
  • Practitioner: You make important life decisions—career, relationships, values—and recognize that you cannot blame circumstances, society, or fate for your choices. You own your decisions completely, accepting both the freedom and the burden they bring. This ownership transforms guilt and anxiety into authentic engagement with life.
  • Advanced: You understand that creating meaning in an indifferent universe requires ongoing commitment and repeated choices. There is no final answer—only continuous effort to live authentically while accepting that your choices remain ultimately your own responsibility, even as circumstances and understanding evolve.

​
Origin

While the term “existentialism” was not coined until the mid-20th century, its conceptual foundations were laid in the 19th century by Danish philosopher Søren Kierkegaard and German philosopher Friedrich Nietzsche. Both challenged the rationalist tradition that dominated European philosophy, arguing that abstract reasoning could not address the fundamental questions of human existence. Kierkegaard (1813-1855) attacked the comfortable certainties of bourgeois Christianity, insisting that genuine faith required a “leap of faith” beyond rational justification. He emphasized individual subjective experience and the existential choice to commit to a way of life. Nietzsche (1844-1900) declared that “God is dead” and challenged all transcendent sources of meaning. His concept of the “will to power” and the Übermensch (overman) proposed that individuals could create their own values rather than inheriting them from society or religion. The movement gained its popular form in post-World War II France. Jean-Paul Sartre (1905-1980) became its most visible proponent, especially after his 1945 lecture “Existentialism is a Humanism” made the philosophy accessible to the general public. Simone de Beauvoir, Albert Camus, and Gabriel Marcel contributed to the movement’s development, making existentialism the dominant intellectual force of the 1940s and 1950s.

Key Points

1

Existence Precedes Essence

There is no predetermined human nature or purpose. You exist first, then define yourself through choices. This is Sartre’s famous formulation: “existence precedes essence.” You are not born with a fixed identity—you create it through action.
2

Radical Freedom and Responsibility

Humans are “condemned to be free”—we cannot escape making choices, and we are fully responsible for their consequences. Even refusing to choose is itself a choice. There is no hiding behind circumstances, nature, or social roles.
3

Angst and Authenticity

The awareness of freedom produces existential anxiety (angst). This is not a pathology but the natural response to genuine freedom. Living authentically means acknowledging this anxiety rather than hiding behind “bad faith” (self-deception).
4

Creating Meaning in an Absurd World

The universe is indifferent to human concerns—the “absurd” arises from the conflict between our desire for meaning and the universe’s silence. Rather than despair, this recognition can motivate individuals to create their own meaning.

​
Applications

Personal Decision Making

Existentialism provides a framework for making difficult choices by accepting full responsibility rather than seeking external validation. It encourages authentic decision-making that reflects individual values rather than societal expectations.

Therapy and Psychology

Existential therapy addresses issues like meaninglessness, isolation, and mortality by helping individuals confront these fundamental anxieties and create authentic responses rather than avoiding them.

Leadership and Ethics

Existentialist ethics emphasizes individual responsibility for choices and their consequences, challenging leaders to make authentic decisions rather than hiding behind groupthink or institutional authority.

Creative Work

Artists, writers, and creators draw on existentialist themes to explore questions of meaning, identity, and authenticity, producing works that resonate with the human condition.

Case Study

Jean-Paul Sartre’s development of existentialism illustrates the philosophy’s emergence from historical crisis. After serving in World War I—where he was briefly captured—and then witnessing the devastation of World War II and the Holocaust, Sartre confronted directly the question of human freedom in a world that seemed to offer no guarantees. In 1943, during the German occupation of France, Sartre premiered his play “No Exit” (Huis Clos), featuring three characters locked in a room for eternity. The famous conclusion—“Hell is other people”—captured existentialism’s focus on the anxiety of freedom and the responsibility we cannot escape, even in death. After the war, Sartre’s 1945 lecture “Existentialism is a Humanism” attempted to defend the philosophy against critics who claimed it led to moral nihilism. Sartre argued that because humans are completely free and responsible, they must recognize the freedom of others—this is the basis of existentialist ethics. Sartre famously refused the Nobel Prize in Literature in 1964, stating he did not want to be “bound” by any institution. This act embodied the existentialist principle that the individual must create their own values rather than accept external recognition.

​
Boundaries and Failure Modes

Existentialism is often criticized for its perceived pessimism or nihilism. However, existentialists argue that confronting meaninglessness is not the same as endorsing it. The recognition of an indifferent universe can motivate rather than paralyze. The philosophy can also be psychologically demanding. Accepting complete responsibility for one’s life without the comfort of predetermined purpose can produce anxiety that some find overwhelming. Critics argue this places unfair psychological burdens on individuals. Additionally, existentialist emphasis on individual freedom can appear to neglect social and political structures that constrain choice. Later thinkers, particularly those in the Frankfurt School, developed critical theory to address these concerns.

​
Common Misconceptions

Correction: While existentialism takes an honest look at the absence of inherent meaning, many existentialists—including Sartre and Camus—argued this recognition is liberating, not depressing. Creating your own meaning is an affirmative act.
Correction: Existentialism does not say nothing matters—it says everything matters because you choose it. Sartre argued that recognizing our freedom creates moral responsibility to respect others’ freedom.
Correction: While existentialists take anxiety seriously, they also emphasize engagement, creativity, and authentic living. The philosophy offers tools for meaningful existence, not resignation.
Existentialism connects to other philosophical traditions and concepts.

Absurdism

The philosophical concept that arises from the conflict between human desire for meaning and the universe’s indifferent silence, famously explored by Albert Camus.

Nihilism

The rejection of all religious and moral principles, often seen as a potential outcome of existential reflection, though existentialists typically reject it as “bad faith.”

Phenomenology

The philosophical method developed by Edmund Husserl that influenced existentialist approaches to consciousness and experience.

One-Line Takeaway

You are free—and that freedom is terrifying. But in that terror lies the possibility of creating something meaningful where nothing was given.
