1813-1855 CE
Truth is subjectivity — you become yourself not through rational understanding but through passionate choice, anxiety, and the leap of faith.
Søren Aabye Kierkegaard was born in Copenhagen on 5 May 1813, the youngest of seven children born to Michael Pedersen Kierkegaard and his second wife Ane. His father was a wealthy merchant who had retired young, devoting himself to philosophy and theology. But the household was overshadowed by guilt and melancholy. Michael had cursed God as a poor shepherd boy on the Jutland heath, and he believed the curse had doomed his family. When five of his seven children died young, it seemed like confirmation. Søren inherited his father’s melancholy and his obsessive religious anxiety.
He was educated at home until ten, then attended the School of Civic Virtue. In 1830, he enrolled at the University of Copenhagen to study theology, his father’s wish. But he wandered: he attended lectures in everything, read voraciously, lived the aesthetic life — theater, cafés, running up debts. His father wanted a pastor; Søren wanted to think and write. In 1838, his father died, reconciled to Søren at the end. The death liberated and devastated him. He resolved to finish his degree and become serious.
In 1840, he met Regine Olsen, a sixteen-year-old girl from a respectable family. He fell completely in love — the only time, he said later, that he had been truly happy. He proposed in September 1840; she accepted. For a year, they were engaged. Then, in August 1841, Kierkegaard broke it off. Why? He said he wasn’t suited for marriage, that his melancholy would destroy her, that he was too old for her (he was 28, she was 18), that he had a religious vocation that required solitude. Regine was devastated. Within two years, she married someone else. Kierkegaard never recovered. He wrote about the broken engagement obsessively — in Fear and Trembling (Abraham sacrificing Isaac = Kierkegaard sacrificing Regine), in Repetition, in Stages on Life’s Way. It became his existential laboratory.
From 1843 to 1846, he published an astonishing torrent of books, many under pseudonyms. Either/Or (1843) presented two life-views: the aesthetic (Judge Wilhelm) and the ethical (Judge Wilhelm), with no resolution — the reader must choose. Fear and Trembling (1843) explored Abraham’s willingness to sacrifice Isaac: the teleological suspension of the ethical, faith as absurdity. Philosophical Fragments (1844) and Concluding Unscientific Postscript (1846) attacked Hegelian objectivity and defended subjective truth. The Concept of Anxiety (1844) and The Sickness Unto Death (1849) analyzed the structure of human existence: anxiety as freedom’s possibility, despair as the self’s failure to be itself.
Why pseudonyms? To create indirect communication. Kierkegaard didn’t want to preach; he wanted readers to confront choice. The pseudonyms — Johannes Climacus, Anti-Climacus, Johannes de Silentio, Victor Eremita — represent different life-stages and perspectives. The reader must navigate them and decide. It’s the opposite of a system: it’s deliberately fragmentary, contradictory, requiring personal engagement.
In 1846, The Corsair, a satirical weekly, began mocking him viciously — his appearance, his odd gait, his broken engagement, his pretensions. At first, Kierkegaard had invited the attack (he wanted to be taken seriously, not praised by a scandal sheet), but the relentless mockery hurt deeply. He became a laughingstock in Copenhagen. Children followed him in the street, mocking his walk. He became more isolated, more bitter.
In his final years, he turned from philosophy to theology and from theology to prophetic attack. He was convinced that Danish Christendom — where everyone was baptized, everyone confirmed, everyone Christian by default — was a betrayal of the Gospel. Christianity is a scandal, a paradox, a crucifixion. It demands everything. Danish Christianity demanded nothing; it was comfortable, bourgeois, aesthetic. In 1854-55, after the death of Bishop Mynster (whom Kierkegaard’s brother called a “witness to the truth”), Kierkegaard launched a ferocious public campaign against the State Church. He published articles, pamphlets, a journal called The Moment. He refused to attend church. He called pastors liars and the Church a criminal conspiracy.
On 2 October 1855, he collapsed in the street. He was taken to Frederik’s Hospital, paralyzed from the waist down. For six weeks, he lingered. His brother Peter, a pastor, begged him to take communion. Søren refused: not from an official clergyman, a servant of the state, not of God. He died on 11 November 1855. His funeral was a scandal: the Church tried to claim him; students protested, shouting that the Church had no right to bury a man who had denounced it. He was buried in the family plot in Assistens Cemetery. He was 42 years old.
He left behind thousands of pages: published works, journals, letters. The journals, in particular, are extraordinary — a record of melancholy, doubt, faith, despair, prayer. He wrote to understand himself and to help others understand themselves. He succeeded, though not in his lifetime. Denmark ignored him; Europe discovered him decades later.
"The thing is to find a truth which is true for me, to find the idea for which I can live and die."
— Journal entry, 1 August 1835 — the young Kierkegaard searching for his vocation
"Truth is subjectivity. An objective uncertainty held fast in an appropriation-process of the most passionate inwardness is the truth, the highest truth attainable for an existing individual."
— Concluding Unscientific Postscript (1846) — defining subjective truth against Hegelian objectivity
"The self is a relation which relates itself to itself... Despair is a sickness in the self, it is either not willing to be oneself, or willing to be oneself."
— The Sickness Unto Death (1849) — analyzing despair as the fundamental misrelation of the self
Kierkegaard’s philosophy is anti-systematic by design. Systems pretend to comprehend everything; existence escapes comprehension. Systems are complete; existence is becoming. Systems are objective; existence is subjective. So rather than building a system, Kierkegaard creates a series of perspectives, pseudonyms, and experiments to help the reader confront choice.
The stages on life’s way: Kierkegaard identifies three fundamental modes of existence — the aesthetic, the ethical, and the religious. The aesthetic life pursues pleasure, beauty, novelty. Its exemplar: Don Juan, the seducer. Its method: rotation, constantly seeking new experiences to avoid boredom. Its problem: it ends in despair because finite pleasures can’t satisfy infinite desire. Judge Wilhelm in Either/Or represents the aesthetic at its most refined: he knows pleasure is empty but can’t escape it.
The ethical life chooses duty, commitment, universal principles. Its exemplar: Judge Wilhelm in Either/Or Volume II, who defends marriage, work, social responsibility. The ethical individual chooses himself, takes responsibility, lives according to universal moral law. Its advantage: it gives life meaning and coherence. Its problem: it can’t handle guilt, radical freedom, or the particularity of the individual. It assumes we can fulfill the moral law; experience shows we can’t. It points to universal principles; existence is radically individual.
The religious life is the highest. It begins with anxiety — the dizziness of freedom, the realization that we are not grounded in ourselves. It moves through despair — the sickness of the self that wills to be itself (defiance) or wills not to be itself (weakness). And it arrives, if it arrives, at faith — the absurd trust in God despite the impossibility, the leap that suspends the ethical (Abraham), the passionate appropriation of paradox (Christ as God-man).
But Kierkegaard distinguishes two forms of religious life. Religiousness A: the inward relationship to the eternal, accessible to reason and universal moral effort. Religiousness B: Christianity, which adds the paradox of the Incarnation and the offense of the Cross. Christianity is not a philosophy; it’s a scandal. It can’t be understood; it can only be believed. And belief is not intellectual assent but existential transformation.
The structure of the self: In The Sickness Unto Death, Kierkegaard defines the self as “a relation which relates itself to itself.” The self is not a substance but a process, a task. You become yourself by relating to yourself and, ultimately, by relating to God (the power that established the self). Despair is the failure of this relation — either not willing to be oneself (weakness, wanting to escape) or willing to be oneself in defiance (pride, wanting to ground oneself in oneself). Both are forms of misrelation. Health is faith: willing to be oneself in transparent dependence on God.
Anxiety and freedom: In The Concept of Anxiety, Kierkegaard analyzes anxiety (Angst) as freedom’s possibility. Before Adam sinned, there was innocence — not virtue but ignorance. God forbade eating from the tree, creating the possibility of choice. Anxiety is the dizziness that accompanies this possibility: not fear of something specific but the vertiginous awareness of freedom itself. Sin enters when anxiety chooses itself — when possibility becomes actuality. But anxiety is not sin; it’s the precondition of freedom. Without anxiety, we would be animals or angels, not humans.
Subjectivity and truth: Against Hegel’s objective Spirit and rational necessity, Kierkegaard insists that truth is subjectivity. This doesn’t mean relativism (your truth, my truth). It means that religious and ethical truth cannot be grasped objectively, as a spectator contemplates a theorem. They require passionate inwardness, personal appropriation, existential commitment. The question is not “What is Christianity?” but “Am I a Christian?” Not knowledge but transformation.
He illustrates with the distinction between objective and subjective reflection. Objective reflection asks: Is Christianity true? It examines evidence, weighs probabilities, never reaches certainty. Subjective reflection asks: How do I relate to Christianity? It focuses on the existing individual’s appropriation, the inwardness with which he holds the belief. The result: “An objective uncertainty held fast in an appropriation-process of the most passionate inwardness is the truth, the highest truth attainable for an existing individual.”
This leads to the paradox of faith. Christianity asserts that God became man, that the eternal entered time, that the infinite became finite. This is objectively absurd — it violates logical and historical reason. Faith is precisely the passionate commitment to this absurdity. Not blind faith (ignoring the absurd) but seeing the absurd clearly and choosing it anyway. The knight of faith performs the double movement: infinite resignation (giving up the finite) followed by faith (receiving the finite back as gift). Abraham gives up Isaac; he also believes he will get Isaac back. This is higher than tragic resignation because it embraces paradox.
Indirect communication: Kierkegaard rejects direct teaching. If he writes “Christianity is true” under his own name, readers might agree intellectually without changing. So he writes under pseudonyms, presenting different perspectives — aesthetic, ethical, religious — without endorsing any. The reader must wrestle, choose, become existentially engaged. The form is the message: existence is not observed; it’s lived.
The attack on Christendom: In his final writings, Kierkegaard turns prophetic. Denmark is officially Christian; everyone is baptized. But this makes Christianity easy, cultural, bourgeois. Real Christianity is martyrdom — literally, “witness.” It requires suffering, sacrifice, dying to the world. The comfortable state church is the opposite of the Gospel. Pastors are paid to proclaim a message that, if truly preached, would cost them everything. Kierkegaard demands honesty: either admit Christendom is not Christianity, or take up the Cross. He died making this case.
