30 Soren Kierkegaard Quotes on Anxiety, Faith & Existence
Soren Kierkegaard (1813-1855) was a Danish philosopher, theologian, and cultural critic who is widely regarded as the father of existentialism. The youngest of seven children in a wealthy Copenhagen family shadowed by his father's melancholy and religious guilt, Kierkegaard wrote prolifically under a dizzying array of pseudonyms, producing works that explored anxiety, despair, faith, and the nature of authentic existence. He died at 42, collapsing on the street and refusing communion from the state church he had spent his final years attacking.
In 1841, Kierkegaard made the agonizing decision to break off his engagement to Regine Olsen, the woman he loved deeply. He believed that his melancholic temperament and his philosophical calling made him unfit for marriage, and he spent years crafting elaborate explanations for the rupture, producing some of his greatest works -- Either/Or, Fear and Trembling, and Repetition -- in a burst of creative anguish fueled by the loss. The broken engagement became the central event of his life, a personal wound he transformed into a universal meditation on the impossibility of reconciling the demands of the finite and the infinite. As he wrote: "Life can only be understood backwards; but it must be lived forwards." That paradox -- that we must make our most important choices in uncertainty, understanding their meaning only in retrospect -- became the foundational insight of existentialist philosophy.

Key Achievements and Episodes
The Broken Engagement That Fueled His Philosophy
In 1841, Kierkegaard broke off his engagement to Regine Olsen, the woman he loved deeply. He believed his melancholic temperament made him unfit for marriage. The anguish of this decision fueled an extraordinary creative outburst: he published Either/Or, Fear and Trembling, and Repetition within two years, transforming personal pain into universal philosophy.
Writing Under a Dizzying Array of Pseudonyms
Kierkegaard published many of his most important works under pseudonyms — Johannes de Silentio, Johannes Climacus, Anti-Climacus, and others. Each pseudonym represented a different philosophical perspective, allowing Kierkegaard to explore contradictory viewpoints without committing to a single position. This technique anticipated modernist literary experimentation by decades.
The Attack on the Danish State Church
In the final year of his life, Kierkegaard launched a ferocious public attack on the Danish State Church, publishing a series of pamphlets called "The Moment." He argued that institutional Christianity had betrayed Christ's radical message. He collapsed on the street in October 1855 and died a month later at age 42, refusing communion from any state-appointed pastor.
Who Was Kierkegaard?
Soren Aabye Kierkegaard was born on May 5, 1813, in Copenhagen, the youngest of seven children. His father, Michael Pedersen Kierkegaard, was a wealthy retired merchant haunted by a deep religious melancholy -- a temperament he passed on to his son. Kierkegaard studied theology and philosophy at the University of Copenhagen, where he encountered and fiercely opposed the dominant Hegelian system that claimed to explain all of reality through abstract reason.
The pivotal personal event of Kierkegaard's life was his engagement to Regine Olsen in 1840, followed by his agonizing decision to break it off in 1841. He loved her deeply, but believed that his melancholic nature and his calling as a writer made him unsuitable for marriage. The pain of this sacrifice echoed throughout his works, particularly in Either/Or (1843) and Repetition (1843), where he explored the tension between the aesthetic life of pleasure and the ethical life of commitment. Regine became a haunting presence in his philosophy -- the living embodiment of the choices and renunciations that define a human life.
Kierkegaard's literary strategy was unlike anything philosophy had seen. He published many of his major works under pseudonyms, each representing a different existential standpoint. Johannes de Silentio, the author of Fear and Trembling, meditated on Abraham's willingness to sacrifice Isaac as the supreme example of faith beyond reason. Johannes Climacus, credited with Concluding Unscientific Postscript, attacked the idea that truth could ever be a purely objective system. Anti-Climacus, the author of The Sickness Unto Death, diagnosed despair as the universal human condition. Through these voices, Kierkegaard forced readers to confront ideas from the inside rather than observe them from a safe philosophical distance.
In the final years of his life, Kierkegaard launched a devastating public attack on the Danish State Church, which he saw as a comfortable institution that had stripped Christianity of its radical, life-transforming demand. Through a series of pamphlets called The Moment (1855), he argued that the established church had turned the suffering and paradox of genuine faith into a respectable social convention. The campaign consumed his remaining energy. On October 2, 1855, Kierkegaard collapsed on a Copenhagen street. He died on November 11, 1855, at the age of 42, refusing communion from a state-church pastor. His influence, largely unrecognized in his lifetime, would go on to shape existentialism, theology, psychology, and literature for generations to come.
Kierkegaard Quotes on Anxiety and Despair
Kierkegaard quotes on anxiety and despair penetrate to the existential core of human experience with a psychological insight that anticipated Freud by half a century. His famous definition of anxiety as "the dizziness of freedom" — from The Concept of Anxiety (1844) — captures the vertiginous sensation that accompanies the realization that we are free to choose and that nothing predetermined guarantees the rightness of our choices. Kierkegaard wrote this work under the pseudonym Vigilius Haufniensis, one of the many fictional authors he employed to present different philosophical perspectives without committing himself to any single viewpoint. His analysis of anxiety was deeply personal: haunted by his father's melancholy and religious guilt, by the deaths of five of his seven siblings, and by the agonizing decision to break his engagement to Regine Olsen, Kierkegaard experienced the "dizziness of freedom" as an intimate reality rather than a philosophical abstraction. His companion work The Sickness Unto Death (1849) extended this analysis to despair, which he defined as the failure to be oneself — a condition he believed was universal, though most people remain unconscious of it.
"Anxiety is the dizziness of freedom."
The Concept of Anxiety (1844) -- Kierkegaard's most famous insight about anxiety. We feel dread not because we lack choices, but because we face an overwhelming openness of possibility. Freedom itself is what terrifies us.
"The most common form of despair is not being who you are."
The Sickness Unto Death (1849) -- For Kierkegaard, despair is not merely sadness but a fundamental misrelation within the self. The deepest despair comes from refusing to become the person you truly are.
"Despair is the sickness unto death -- not in the sense that the illness leads to physical death, but that the sufferer is unable to die, is forced to go on living in a state of death."
The Sickness Unto Death (1849) -- Kierkegaard redefines despair as something worse than death: a living death in which the self is trapped in its own failure to relate properly to itself and to God.
"Anxiety may be compared with dizziness. He whose eye happens to look down into the yawning abyss becomes dizzy. But what is the reason for this? It is just as much in his own eye as in the abyss."
The Concept of Anxiety (1844) -- Anxiety is not caused by external dangers alone. It arises from within, from our awareness that we are free beings standing before an infinite range of possibilities.
"Not to be in despair can mean either that one is in despair or that one has overcome despair. Not being in despair can be the same as not being aware of being in despair."
The Sickness Unto Death (1849) -- One of Kierkegaard's most unsettling observations: the most dangerous form of despair is the kind you do not know you are in. Unconscious despair is still despair.
"Deep within every human being there still lives the anxiety over the possibility of being alone in the world, forgotten by God, overlooked among the millions in this enormous household."
Journals and Papers (1847) -- A profoundly personal entry from Kierkegaard's private journals, revealing the existential loneliness that haunted him and that he believed all human beings share at the deepest level.
"Whoever has learned to be anxious in the right way has learned the ultimate."
The Concept of Anxiety (1844) -- Kierkegaard does not want us to eliminate anxiety but to learn from it. Properly understood, anxiety is a teacher that opens us to the depth and seriousness of existence.
"The greatest hazard of all, losing one's self, can occur very quietly in the world, as if it were nothing at all."
The Sickness Unto Death (1849) -- Unlike losing a limb or a fortune, losing your true self happens silently. The world will not alert you. You can forfeit your own identity without anyone noticing -- including yourself.
Kierkegaard Quotes About Faith and Belief
Kierkegaard quotes about faith and belief express his radical vision of religious commitment as a passionate, individual leap beyond the reach of rational proof. His teaching that "the function of prayer is not to influence God, but rather to change the nature of the one who prays" redefines religious practice as a form of self-transformation rather than an attempt to manipulate a cosmic power. Kierkegaard's most sustained exploration of faith appears in Fear and Trembling (1843), where he meditates on the biblical story of Abraham's willingness to sacrifice Isaac, arguing that Abraham's faith transcends ethical reasoning and represents a "teleological suspension of the ethical" — a direct, personal relationship with God that cannot be justified in universal terms. Written under the pseudonym Johannes de Silentio, this work was composed in the months following his break with Regine, and scholars have read it as both a philosophical investigation and an encrypted personal confession. Kierkegaard's fierce attacks on the established Danish Church in his final years — published in his own journal The Moment — argued that comfortable, culturally accommodated Christianity was a betrayal of the radical demands of genuine faith.
"The function of prayer is not to influence God, but rather to change the nature of the one who prays."
Purity of Heart Is to Will One Thing (1847) -- Prayer, for Kierkegaard, is not a transaction with God but a transformation of the self. It is the person praying who is reshaped by the act.
"A leap of faith -- to believe in something that is not immediately apparent, beyond reason and evidence."
Concluding Unscientific Postscript (1846) -- Kierkegaard's most famous concept. Authentic faith cannot be reached through logical proofs or philosophical arguments. It requires a passionate, personal leap beyond rational certainty.
"If I am capable of grasping God objectively, I do not believe, but precisely because I cannot do this I must believe."
Concluding Unscientific Postscript (1846) -- Faith exists precisely where knowledge ends. If God could be proven like a mathematical theorem, faith would be unnecessary and meaningless.
"The knight of faith is the individual who is able to renounce everything and then, by virtue of the absurd, receive everything back again."
Fear and Trembling (1843) -- The "knight of faith" is Kierkegaard's ideal. Unlike the tragic hero, who gives up something for a higher ethical purpose, the knight of faith surrenders everything and trusts that the impossible will be restored.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true."
Works of Love (1847) -- Kierkegaard warns against both gullibility and cynicism. Both the naive believer and the hardened skeptic are equally deceived, just in opposite directions.
"The Bible is very easy to understand. But we Christians are a bunch of scheming swindlers. We pretend to be unable to understand it because we know very well that the minute we understand, we are obliged to act accordingly."
Provocations: Spiritual Writings of Kierkegaard (compiled from Journals) -- A biting critique of comfortable Christianity. Kierkegaard believed that understanding scripture was never the real problem; the problem was the courage to live it.
"To dare is to lose one's footing momentarily. Not to dare is to lose oneself."
Journals and Papers -- A compact expression of Kierkegaard's philosophy of risk. Playing it safe may feel secure, but it costs you the most valuable thing you have: your authentic selfhood.
"Without risk there is no faith, and the greater the risk, the greater the faith."
Concluding Unscientific Postscript (1846) -- Faith and certainty are opposites. Genuine faith exists only in conditions of uncertainty and vulnerability. A faith that requires no risk is not faith at all.
Kierkegaard Quotes on Life and Existence
Kierkegaard quotes on life and existence contain some of the most memorable observations in the philosophical canon. His insight that "life can only be understood backwards; but it must be lived forwards" captures the fundamental temporal paradox of human existence: we can make sense of our experiences only in retrospect, yet we must make our choices in the present, facing an unknown future. This observation, from his journal of 1843, reflects Kierkegaard's broader existential philosophy, which insists that truth is not an abstract proposition to be contemplated but a lived reality to be engaged through passionate commitment. His 1843 masterwork Either/Or — an 800-page exploration of the aesthetic and ethical modes of existence — was written in an extraordinary burst of productivity following his broken engagement with Regine. Over the next decade, writing at furious speed (sometimes producing two or three books in a single year), Kierkegaard developed the existentialist themes — authenticity, choice, anxiety, the absurd, the leap of faith — that would later influence Heidegger, Sartre, Camus, and the entire existentialist movement.
"Life can only be understood backwards; but it must be lived forwards."
Journals and Papers (1843) -- Perhaps Kierkegaard's single most quoted line. We can see the meaning of our experiences only in hindsight, yet we must make our choices facing forward into an unknown future.
"People demand freedom of speech as a compensation for the freedom of thought which they seldom use."
Either/Or (1843) -- A sharp and witty observation. Kierkegaard suggests that the loudest demands for external freedom often mask an inner laziness -- the refusal to think independently.
"Once you label me, you negate me."
Attributed to Kierkegaard, widely associated with his philosophy -- A label reduces a living, breathing individual to a category. Kierkegaard devoted his entire career to defending the irreducible uniqueness of the individual against all systems and abstractions.
"Boredom is the root of all evil -- the despairing refusal to be oneself."
Either/Or (1843) -- In the aesthetic section of Either/Or, Kierkegaard's pseudonym argues that boredom is not merely an inconvenience but a symptom of spiritual emptiness and the avoidance of authentic existence.
"What I really need is to get clear about what I must do, not what I must know, except insofar as knowledge must precede every act."
Journals and Papers (1835, the "Gilleleie" entry) -- Written at age 22, this journal entry captures the central question that would drive Kierkegaard's entire life and philosophy: not what is true in the abstract, but what is true for me.
"The tyrant dies and his rule is over, the martyr dies and his rule begins."
Journals and Papers -- Kierkegaard contrasts the fleeting power of force with the enduring power of sacrifice. Those who die for truth exert a greater influence than those who rule by coercion.
"Subjectivity is truth."
Concluding Unscientific Postscript (1846) -- One of Kierkegaard's most provocative claims. He does not deny objective facts, but insists that the truths that matter most -- about how to live, what to believe, who to become -- are always personally appropriated.
Kierkegaard Quotes About Love and Relationships
Kierkegaard quotes about love and relationships are inseparable from the great biographical drama that shaped his philosophy: his tortured love for Regine Olsen. His simple yet profound exhortation to "don't forget to love yourself" reflects the psychological insight, developed in Works of Love (1847), that genuine love of others requires a healthy relationship with oneself. In 1841, Kierkegaard made the agonizing decision to return his engagement ring to Regine, despite being deeply in love with her, because he believed his melancholic temperament and philosophical calling made him unfit for the intimacy of marriage. He spent years crafting elaborate philosophical works that were, on one level, encoded messages to Regine — attempts to explain and justify a decision that tormented him for the rest of his life. His analysis of the different spheres of existence — the aesthetic (living for pleasure), the ethical (living by duty), and the religious (living by faith) — can be read as stages through which his love for Regine was transformed from romantic passion to ethical commitment to religious resignation. Kierkegaard died on November 11, 1855, at the age of forty-two, collapsing on the street in Copenhagen, having spent his final months in a fierce public battle against the Danish Church.
"Don't forget to love yourself."
Works of Love (1847) -- In a book devoted to the Christian command to love your neighbor, Kierkegaard pauses to remind us that self-love is not selfishness but the necessary foundation from which all genuine love for others flows.
"When you open the door which you have shut in order to pray to God, the first person you meet as you go out is your neighbour whom you shall love. Wonderful!"
Works of Love (1847) -- Kierkegaard insists that faith and love of neighbor are inseparable. The moment you leave the privacy of prayer, the command to love confronts you immediately in the face of another person.
"If you want to be loathsome to God, just run with the herd."
Journals and Papers -- A fierce rejection of crowd mentality. For Kierkegaard, authentic selfhood and genuine faith both require standing apart from the unthinking mass. The individual, not the crowd, is the fundamental category of existence.
"Love is all, it gives all, and it takes all."
Works of Love (1847) -- A deceptively simple statement that captures love's total nature. Genuine love demands complete giving and complete vulnerability. It is not a partial commitment but a total one.
"The crowd is untruth. Only the individual can stand before God."
The Point of View for My Work as an Author (published posthumously, 1859) -- Kierkegaard's most direct statement of his core conviction. The crowd dissolves individual responsibility, and with it the possibility of authentic faith, love, and moral choice.
"Love does not alter the beloved, it alters itself."
Works of Love (1847) -- True love does not seek to change the other person to suit its preferences. Instead, love transforms the one who loves, deepening their patience, generosity, and capacity for acceptance.
"Marry, and you will regret it; don't marry, you will also regret it; marry or don't marry, you will regret it either way."
Either/Or (1843) -- From the famous "diapsalmata" section, this passage captures the aesthetic view of life as an ironic trap. Every choice closes off alternatives, and regret follows every path. It reads as both darkly humorous and deeply personal, echoing Kierkegaard's own tormented decision to break his engagement with Regine Olsen.
Frequently Asked Questions About Soren Kierkegaard
What are the most famous Soren Kierkegaard quotes?
The most famous Soren Kierkegaard quotes include: "Life can only be understood backwards; but it must be lived forwards" (from his Journals, 1843), "Anxiety is the dizziness of freedom" (from The Concept of Anxiety, 1844), "The most common form of despair is not being who you are" (from The Sickness Unto Death, 1849), and "People demand freedom of speech as a compensation for the freedom of thought which they seldom use." Kierkegaard is called the father of existentialism because he placed individual subjective experience, personal choice, and anxiety at the center of philosophical inquiry. His concepts of Angst, despair, the leap of faith, and authentic selfhood became the foundation for 20th-century thinkers including Sartre, Camus, and Heidegger.
What is Kierkegaard's leap of faith?
Kierkegaard's leap of faith describes the act of believing in something that cannot be rationally proven or logically demonstrated -- specifically, religious faith in God. Kierkegaard argued that rational argument can never prove God's existence or the truth of Christianity; at some point, the individual must make a passionate, subjective commitment that goes beyond what reason can justify. This leap is not irrational but trans-rational -- it acknowledges the limits of reason and embraces uncertainty. Kierkegaard saw Abraham's willingness to sacrifice Isaac in Fear and Trembling (1843) as the paradigm of faith: a commitment so radical that it suspends ordinary ethical rules and can never be justified in universal, rational terms.
What are Kierkegaard's three stages of existence?
Kierkegaard described three stages or spheres of existence through which an individual can live: the aesthetic, the ethical, and the religious. The aesthetic stage is characterized by the pursuit of pleasure, novelty, and immediate experience, exemplified by Don Juan or the seducer. The ethical stage involves commitment to moral duty, social responsibility, and personal relationships, exemplified by the faithful spouse. The religious stage involves a personal relationship with God that transcends both pleasure and duty, exemplified by Abraham. Kierkegaard argued that one cannot reason one's way from one stage to the next but must make a leap of commitment. Each transition requires a crisis that reveals the inadequacy of the current mode of existence.
