'World war and economic depression undermined confidence in science and reason, encouraging existentialism and later postmodernism.'
Twentieth-century crises shattered older faith in steady progress. European thinkers increasingly questioned whether science, reason, and modern politics could still explain human life or give it moral direction.
Why Crisis Changed European Thought
From Progress to Disillusionment
In the nineteenth century, many Europeans believed science, reason, and progress would steadily improve society. Industrial growth, new technologies, and scientific discovery seemed to support that confidence. The early twentieth century badly damaged this outlook.
World War I exposed the destructive side of modern technology: machine guns, poison gas, artillery, and trench warfare produced mass slaughter.

The war also weakened the belief that educated, “civilized” societies naturally behaved rationally.
The Great Depression further discredited confidence in rational systems by showing that modern economies could collapse suddenly and throw millions into insecurity.
World War II, genocide, and state-directed violence deepened the crisis. Bureaucratic efficiency and scientific planning could now be associated not only with progress, but also with extermination and total war.
The crisis was also psychological. If modern civilization could produce both advanced chemistry and gas attacks, both mass literacy and propaganda, then older assumptions about rational improvement seemed dangerously naive.
For many intellectuals, the lesson was not that science was useless, but that science alone could not answer questions about meaning, freedom, morality, or the value of human life. The result was not anti-intellectualism; rather, it was a more self-critical intellectual climate.
Existentialism: Meaning After Catastrophe
Core Ideas
Existentialism became one of the most influential responses to this crisis.
A philosophical outlook emphasizing individual existence, freedom, choice, and responsibility in a world that offers no guaranteed meaning.
Existentialist thinkers argued that human beings are not given a fixed purpose by history, science, or social systems. Instead, people must confront freedom, anxiety, isolation, and death, then create meaning through action. This outlook appealed strongly in a Europe marked by occupation, collaboration, resistance, and moral uncertainty.
Key themes of existentialism included:
Freedom and choice: individuals are “condemned to be free,” in Jean-Paul Sartre’s famous phrase, because they must choose even when certainty is impossible.
Responsibility: people cannot hide behind institutions, tradition, or abstract theories to escape moral accountability.
Authenticity: a person should live honestly, recognizing freedom rather than pretending life is fully controlled by outside forces.
Absurdity: in the work of Albert Camus, human beings search for order in a universe that does not automatically provide it.
Existentialism was shaped by wartime experience. During occupation and dictatorship, questions of personal choice became immediate: whether to obey, resist, collaborate, or remain silent. That gave existentialism unusual moral force in postwar Europe. It appeared not only in philosophy but also in novels, plays, and essays, which helped spread it beyond universities.
Simone de Beauvoir also applied existentialist ideas to social life, arguing that freedom is shaped by concrete conditions and that oppression limits the ability to choose fully.

Her work showed that existentialism could be used not just to describe private anxiety but also to analyze unequal power relationships.
From Existentialism to Postmodernism
New Skepticism
By the later twentieth century, skepticism toward certainty became even broader. Intellectuals increasingly doubted not only moral and political systems, but also the possibility of stable, universal truth claims.
A broad intellectual approach that questions universal truths, fixed identities, and grand narratives, stressing the instability of language, meaning, and knowledge.
Postmodernism grew in a world still shaped by war, dictatorship, propaganda, and ideological conflict. If earlier generations had lost faith in progress, postmodern thinkers went further by asking whether claims to objective truth often masked power.
Important features of postmodernism included:
skepticism toward grand narratives, or large explanatory stories such as inevitable progress, national destiny, or universal liberation
distrust of the idea that language simply mirrors reality
attention to how institutions define what counts as truth, normality, or knowledge
rejection of the assumption that reason leads all people to the same conclusions
Thinkers such as Michel Foucault, Jacques Derrida, and Jean-François Lyotard became associated with this shift. Foucault examined how power and knowledge operate together in modern institutions. Derrida challenged the idea that texts have a single stable meaning. Lyotard argued that the modern age had lost confidence in the big narratives that once claimed to explain history.
Comparison and Historical Significance
Key Distinctions
Existentialism and postmodernism were both responses to crisis, but they were not identical.
Existentialism still centered on the individual subject and asked how a person could live meaningfully in a fractured world.
Postmodernism was more skeptical about the stability of the self, the reliability of language, and the authority of any total explanation.
Existentialists often retained a serious search for ethical responsibility.
Postmodernists more often emphasized fragmentation, ambiguity, and the political uses of truth claims.
These shifts influenced literary criticism, philosophy, and cultural theory. Scholars became more attentive to memory, language, representation, and the limits of objectivity. Twentieth-century European thought moved away from confident claims about inevitable progress toward more self-critical and fragmented interpretations of modern life.
FAQ
Existentialism and nihilism both begin from the sense that life lacks guaranteed meaning.
However, existentialists usually argued that individuals can still create values through choice, commitment, and action. Nihilism is more likely to deny that such created meaning has lasting validity.
Camus thought some existentialists turned human uncertainty into a formal philosophical system. He preferred to describe the absurd, the clash between humanity’s search for meaning and the world’s silence.
For Camus, the proper response was revolt: living lucidly, resisting injustice, and refusing false consolation.
After 1945, Paris was a major centre of publishing, universities, theatres, cafés, and political debate. Ideas could move quickly between philosophers, journalists, novelists, and students.
That mattered because existentialism and later postmodern thought spread not only through specialist books, but also through lectures, journals, performances, and public argument.
Postmodernism encouraged historians to think more carefully about language, archives, and point of view. It raised questions about who produces records and whose voices are left out.
Most historians did not stop using evidence. Instead, many became more self-conscious about narrative structure, memory, and the limits of complete objectivity.
Some critics feared that extreme scepticism could weaken moral judgement. If all truth claims are treated as equally unstable, it becomes harder to condemn racism, dictatorship, or genocide in clear terms.
Others argued that postmodernism focused too heavily on language and discourse while paying too little attention to economics, class, and the coercive power of the state.
