Existentialism

Existentialism is a diverse philosophical and literary movement that begins from lived experience rather than a unified doctrine. Its decisive concern is the individual person confronting suffering, Nothingness, and a world not organized around human purposes; its refusal to let abstract systems override that encounter is both a philosophical position and a response to modern life.

Emergence and Reach

The movement’s reception in the United States accelerated in 1946 and 1947, when Existentialism became a familiar label amid the postwar culture associated with young people in Left Bank cafes. That popular image made it easy to dismiss the movement as a passing fashion. At the same time, its texts—especially those of Sartre—were being translated and studied in serious intellectual circles, where they provoked sharply opposed responses.

Neo-Thomists and other moral philosophers objected to Existentialism’s disregard for traditional schemes of value. Positivists and analytical philosophers, from a different direction, attacked its willingness to set aside rational categories and attend to nonmental processes of consciousness. Small avant-garde groups welcomed it, though their enthusiasm did not necessarily mean they understood it any better than its critics. The force of these competing reactions reflects the movement’s challenge to assumptions shared across otherwise opposed schools.

Existentialist concerns extended beyond philosophy into literature. The account places Sartre alongside thinkers including Martin Heidegger, Karl Jaspers, Gabriel Marcel, Jose Ortega, Martin Buber, Nikolai Berdyaev, and A. N. Whitehead, while tracing related currents through writers such as Kafka, Unamuno, Lawrence, Malraux, Hesse, Camus, and Faulkner. Its reach is presented not as membership in a single school but as a broad alignment of writers and thinkers with questions of individual experience and the limits of rational explanation.

No Single Definition

Existentialism resists a fixed definition because it is not treated as the product of antecedent intellectual determinations. It is described instead as a free transmutation of living experience. The label gathers together writers and thinkers whose approaches diverge; some have rejected the name, yet it remains useful as an agreed term for their shared concerns rather than as a precise statement of doctrine.

This resistance to definition is not a rejection of thought or reason. Existentialists acknowledge reason’s role while insisting that its limits be recognized. Their opposition is directed especially at the rationalist tradition that culminates in Hegel’s effort to unite final reality with ideal reason in a comprehensive system. Against such a synthesis, Existentialism gives weight to experiences—pain, ecstasy, doubt, intuition, private anguish, and despair—that do not fit neatly within rational categories.

The Individual and Nothingness

The movement’s central opposition is to systems that subordinate the particular person to a larger unity. Hegelianism is characterized as a philosophy of history and the mass: it imagines history moving toward a final reality and places individual consciousness within a grand unity of ideal mind. For Existentialism, this fails to account for the self as a present, suffering existent. A system that overrides that suffering is not merely inadequate; it is coercive. The formulation “A crowd is untruth,” attributed to Kierkegaard, expresses the insistence that truth’s drama takes place in the individual self.

Yet turning inward does not uncover a stable, transparent essence. The account describes the self at its center as an absence, and names the ground encountered there Nothingness. This is not simply an empty space but a concept through which Existentialism confronts the question of why anything exists rather than nothing. Facing it brings despair, but the passage also connects that confrontation with existential integrity: the individual must acknowledge the groundlessness of existence instead of hiding it beneath a reassuring system.

Humanism, Contingency, and Historical Experience

Existentialism’s opposition to humanism does not mean indifference to human beings. Its concern is precisely the sanity and efficacy of the individual person. It rejects, however, the anthropocentric assumption that humanity occupies the center of reality and that the nonrational world exists for human purposes. In this account, evolutionary thought itself unsettles that assumption: humanity is a contingent, nonessential arrival, and human works have no guaranteed place in the structure of the universe.

The movement gained particular force in mid-century Europe, amid social chaos, uprootedness, and irrational torture. Such historical experience helps explain the pessimism and nightmarish imagery in much Existentialist writing, but it does not account for the origin of the movement’s insights. Those concerns reach back to thinkers such as Kierkegaard and Nietzsche, whose circumstances were not defined by the catastrophes that shaped later generations. Existentialism therefore treats anguish not as an effect confined to one historical crisis, but as a possibility rooted more deeply in the human condition.

The movement has no single route beyond despair: its major thinkers pursue separate paths toward re-establishing the individual in the face of Nothingness and absurdity. Its breadth is part of its meaning. Existentialism names both a philosophical effort to reckon with the limits of reason and an alteration in ordinary human attitudes, one made newly urgent by modern life but not reducible to its historical disasters.
