Kierkegaard
Kierkegaard turned philosophy away from the system-builder’s map and toward the trembling person who must choose without guarantees, and in doing so made anxiety not a defect in thought but one of its most revealing conditions.

Timeline
Birth of Søren Kierkegaard
**1813-05-05** — Søren Aabye Kierkegaard is born in Copenhagen into a family marked by prosperity, religious seriousness, and melancholy. The domestic atmosphere of guilt and inwardness would become one of the hidden sources of his later philosophy.
Enters the University of Copenhagen
**1830** — Kierkegaard begins formal study in theology and philosophy, entering the intellectual world that would later become his target. His education gives him the tools to criticize the very culture that formed him.
Dissertation on irony and break with Regine Olsen
**1841** — Kierkegaard completes his dissertation, On the Concept of Irony with Continual Reference to Socrates, and in the same year breaks his engagement to Regine Olsen. The year crystallizes his emerging concern with indirectness, choice, and the cost of existence.
Publication of Either/Or and Fear and Trembling
**1843** — Under pseudonyms, Kierkegaard publishes two of his most influential books, setting the aesthetic, ethical, and religious stages into dramatic motion. These works announce the full originality of his indirect style.
Publication of Philosophical Fragments and The Concept of Anxiety
**1844** — Kierkegaard deepens his account of subjectivity, freedom, and anxiety through two major works. The first examines the relation between truth and the moment of revelation; the second makes dread a philosophical category tied to freedom.
Publication of Concluding Unscientific Postscript
**1846** — This massive work articulates the famous contrast between objective truth and subjective appropriation and attacks the pretensions of the system. It became one of the defining texts for later existential and religious interpretations of Kierkegaard.
Publication of The Sickness Unto Death
**1850** — Written under the pseudonym Anti-Climacus, the book offers Kierkegaard’s most developed account of despair as a misrelation in the self. It links anthropology, theology, and existential diagnosis with unusual severity.
Attack on the Danish Church intensifies
**1854** — Kierkegaard’s criticism of Christendom becomes public and sharp, directed at the established Lutheran church and its cultural complacency. The controversy made clear that his philosophical project was also a moral and religious confrontation.
Death of Søren Kierkegaard
**1855-11-11** — Kierkegaard dies in Copenhagen at the age of forty-two, leaving behind a body of work that had not yet become globally famous. His posthumous influence would grow far beyond the Danish setting in which he wrote.
Nietzsche and later modernism begin to echo Kierkegaardian themes
**1880** — Although not a direct public reception moment, the late nineteenth century sees thinkers and writers increasingly gravitate toward problems of anxiety, inwardness, and the isolated self. Kierkegaard’s concerns begin to reappear in secular philosophical and literary forms.
Twentieth-century existential and theological revival
**1930** — Translations and scholarly attention help bring Kierkegaard into broader philosophical and theological circulation. He becomes central to debates about authenticity, faith, and modern subjectivity.
English-language translation and canonization accelerate
**1941** — Mid-century translations make Kierkegaard far more available to anglophone readers, including philosophers, theologians, and literary critics. His work begins to function as a canonical source for existentialism and modern religious thought.
