What Is Existentialism? Key Concepts Explained

Existentialism challenges us to deeply consider our existence, choices, and the meaning we create in life.

TABLE OF CONTENT

Existentialism is a philosophical movement that challenges us to think deeply about our existence, choices, and the meaning we create in life. Emerging in the 19th century and growing in influence during the tumultuous 20th century, existentialism speaks to the complexities of human freedom, responsibility, isolation, and the search for purpose in a universe that seems indifferent to our existence. Unlike other philosophical schools that seek universal answers or predetermined truths, existentialism emphasizes the individual journey, embracing uncertainty, and confronting the anxiety that comes with freedom and self-discovery.

In this article, we will unpack the essential concepts of existentialism, explore its historical roots, and examine its impact on literature, art, psychology, and modern life. By the end, you will have a comprehensive understanding of existentialism’s key principles, historical context, and lasting relevance.


Key Principles of Existentialism

Existentialism’s core principles are grounded in the belief that human beings must create their own meaning in life. These foundational ideas set the stage for understanding the movement’s approach to freedom, authenticity, and the search for purpose.

Existence Precedes Essence

The concept “existence precedes essence” is at the heart of existential thought. This phrase, popularized by Jean-Paul Sartre, suggests that humans are not born with a fixed purpose or essence. In contrast to objects, whose purpose is defined from their creation (such as a knife’s purpose being to cut), human beings have no intrinsic essence. Instead, we create our essence through actions, choices, and experiences.

This idea rejects the notion of a predetermined human nature, instead placing responsibility for self-creation squarely on each individual. Sartre argues that humans are “condemned to be free,” meaning that freedom is an unavoidable condition of existence. Every choice shapes who we become, and we must take full responsibility for the life we build. This freedom is both liberating and burdensome, as it compels individuals to face their role in defining their path, rather than relying on society, religion, or external authorities to dictate their identity.

Freedom and Responsibility

Freedom is one of existentialism’s most celebrated and daunting concepts. Existentialist philosophers argue that individuals possess absolute freedom over their decisions and actions, which gives them control over their destiny. However, this freedom is inseparable from responsibility. Every choice we make, however small, has consequences that affect not only ourselves but also the world around us.

This responsibility can be overwhelming, and existentialists recognize that freedom often brings “angst” or existential anxiety. Angst arises from the awareness that we alone are responsible for shaping our lives. This tension between the boundless potential of freedom and the weight of responsibility can lead to an existential crisis, where individuals question the value of their choices and the meaning of their actions. Yet, existentialism suggests that we must confront this anxiety and embrace freedom as a defining characteristic of human existence.

Absurdity and Anxiety

Absurdity is another defining principle of existentialism, introduced primarily by philosopher Albert Camus. Absurdity refers to the conflict between the human desire for order, meaning, and clarity in life, and the universe’s apparent indifference. According to Camus, life is inherently absurd, as it lacks a clear purpose or objective truth. Humans, who naturally seek answers to questions about existence and purpose, find themselves in a world that offers no easy answers.

This realization can produce a profound sense of existential anxiety or dread, as people confront the possibility that life might be meaningless. However, Camus argues that rather than giving in to despair, we should accept life’s absurdity and live in defiance of it. This approach empowers individuals to create their own meaning despite the world’s indifference. Camus famously illustrates this idea through the myth of Sisyphus, where Sisyphus, condemned to roll a boulder up a hill for eternity, chooses to find joy in his struggle, thereby asserting his own sense of purpose.

Authenticity in Existence

Authenticity is the act of living true to oneself, making choices based on personal beliefs rather than societal expectations. Existentialists argue that authenticity is essential to a meaningful life, as it represents the courage to be oneself and to act according to self-defined values. To live authentically is to confront life’s challenges and anxieties without hiding behind social conventions or conforming to roles imposed by others.

Existential thinkers like Sartre and Simone de Beauvoir stress that authenticity requires a willingness to accept the consequences of one’s choices and to live with integrity. It means rejecting “bad faith,” a state in which individuals deny their freedom and responsibilities, often blaming external forces or succumbing to inauthentic roles. Authenticity involves embracing the responsibility of freedom and making decisions that reflect one’s true self.


Historical Context of Existentialism

Roots in 19th Century Philosophy

Existentialism’s roots trace back to 19th-century European philosophy, with key influences including Søren Kierkegaard and Friedrich Nietzsche. Kierkegaard, often regarded as the father of existentialism, explored the challenges of faith, individuality, and choice. He believed that true individuality could only be achieved by embracing faith and making personal commitments rather than following societal or religious norms. Kierkegaard’s focus on subjective experience and personal truth laid the groundwork for existential thought.

Nietzsche’s contributions also profoundly shaped existentialism, particularly his ideas on nihilism, the “will to power,” and the notion of the “Übermensch” or “overman.” Nietzsche questioned traditional moral values, asserting that humanity must create its own values in a godless world. His famous proclamation, “God is dead,” symbolized the collapse of traditional religious and moral structures, forcing individuals to find meaning independently. Nietzsche’s ideas resonated with later existentialists, who saw his work as a call to embrace freedom and personal responsibility.

The Emergence of Existentialism in Post-War Europe

Existentialism gained prominence in the mid-20th century, particularly after World War II. This period of upheaval, marked by disillusionment and existential questioning, provided fertile ground for existentialist ideas. The war had shattered many people’s faith in social systems, and existentialism’s emphasis on personal responsibility and self-definition resonated deeply.

Philosophers like Jean-Paul Sartre, Simone de Beauvoir, and Albert Camus became key figures in the post-war existential movement. They used existentialism to address the moral and psychological impact of war, exploring themes of alienation, freedom, and ethical ambiguity. Sartre’s works, such as Being and Nothingness and Existentialism is a Humanism, solidified existentialism as a popular philosophical movement.

Influential Thinkers and Their Contributions

  • Jean-Paul Sartre: Sartre emphasized freedom and personal responsibility, arguing that individuals are responsible for shaping their identities and the world around them. His ideas about “bad faith” and authenticity challenged people to take ownership of their lives.
  • Simone de Beauvoir: De Beauvoir applied existentialism to feminism and ethics, advocating for gender equality and women’s liberation. Her work, especially The Second Sex, explores the ways women are often limited by societal expectations and challenges them to live authentically.
  • Albert Camus: Camus focused on the concept of absurdity and the human struggle to find meaning. His works, such as The Stranger and The Myth of Sisyphus, argue that individuals should embrace life’s absurdity and create their own purpose.

Major Themes in Existentialism

Individuality vs. Collectivism

Existentialism places great emphasis on individuality, valuing personal freedom and self-determination over collective norms. This focus on individual agency often conflicts with collectivist ideologies that prioritize the welfare of the group. Existentialists argue that true freedom can only be achieved by recognizing oneself as an individual and rejecting the conformity of societal expectations.

Alienation and Loneliness

Alienation is a recurring theme in existential thought, as individuals are often depicted as isolated in a vast and indifferent world. Existentialists explore the loneliness that arises from this isolation and the struggles of individuals who feel disconnected from society or estranged from their own identity. This alienation, however, also becomes a path to self-discovery and personal growth, as individuals confront their authentic selves.

The Search for Meaning

Existentialism is deeply concerned with the search for meaning, despite the recognition of life’s inherent absurdity. Existentialists argue that while life itself may lack objective meaning, individuals can create their own purpose through choices and actions. This search for meaning is a deeply personal journey, one that each person must undertake independently.


Existentialism in Literature and Art

Existentialism in Literature: Notable Works and Authors

Existentialism has left a lasting impact on literature, with many notable authors using existential themes to explore the human condition. Fyodor Dostoevsky’s Notes from Underground and The Brothers Karamazov delve into themes of freedom, guilt, and moral ambiguity, reflecting existentialist concerns. Franz Kafka’s works, including The Trial and The Metamorphosis, illustrate the alienation and absurdity that characterize existential thought.

Jean-Paul Sartre’s novels, such as Nausea, and Albert Camus’s The Stranger are also pivotal works that reflect existential themes, depicting characters who grapple with freedom, isolation, and the search for purpose.

The Impact of Existentialism on Visual Arts

Existentialism influenced the visual arts as well, particularly in the abstract and surrealist movements. Artists like Edvard Munch and Francis Bacon depicted existential themes through evocative, often unsettling imagery. Munch’s The Scream, for example, captures the anxiety and isolation that existentialists describe, while Bacon’s portraits explore the fragility and intensity of human existence.

Existential Themes in Film and Theatre

Existential themes are also prominent in film and theater, where they challenge audiences to question reality and confront life’s uncertainties. Ingmar Bergman’s The Seventh Seal, a story of a knight confronting death, explores the meaning of life and the inevitability of death. Samuel Beckett’s play Waiting for Godot depicts characters waiting endlessly for an unknown purpose, illustrating the existential themes of absurdity and purposelessness.


Comparisons with Other Philosophical Movements

Existentialism vs. Nihilism

Although existentialism and nihilism both question inherent meaning, they diverge in their conclusions. Nihilism asserts that life is meaningless and advocates for detachment, often leading to despair. Existentialism, however, acknowledges life’s lack of intrinsic meaning but argues that individuals can create purpose through personal choices.

Existentialism vs. Humanism

Existentialism and humanism both emphasize human agency and potential, but their approaches differ. Humanism often advocates for collective progress and ethical development, while existentialism focuses on individual freedom, responsibility, and authenticity.

Existentialism vs. Traditional Philosophical Schools

Traditional philosophy seeks universal truths and rational solutions, whereas existentialism emphasizes personal experience and subjective meaning. Existentialists prioritize lived experience and authenticity, often questioning established doctrines and the quest for objective truth.


Contemporary Relevance of Existentialism

Existentialism in Modern Psychology

Existentialism has significantly influenced psychology, especially in the form of existential psychotherapy. This approach encourages clients to confront questions of freedom, responsibility, and meaning, helping them find purpose despite life’s challenges. Viktor Frankl, a pioneer in existential therapy, developed logotherapy to assist individuals in discovering meaning through suffering and resilience.

The Role of Existentialism in Current Cultural Discourse

Existential themes resonate in contemporary culture, with discussions on personal freedom, authenticity, and identity taking center stage. Existentialism’s ideas on self-discovery, freedom, and meaning appeal to people navigating an increasingly complex and interconnected world.

Reinterpretations of Existentialism Today

Modern thinkers continue to reinterpret existentialism, applying its principles to new challenges such as digital culture, social media, and environmental crises. Existentialism remains relevant in an era that demands adaptability and self-reflection, offering tools for individuals to find meaning in a rapidly changing world.


Existentialism challenges us to face life’s uncertainties, to embrace freedom, and to live authentically. Its focus on individuality, responsibility, and the search for meaning has made it a powerful philosophical influence that continues to shape literature, art, psychology, and modern discourse. Existentialism invites each of us to confront the mystery of existence and to create purpose in a world that often defies easy answers, providing a path for personal growth and self-understanding.
