Soren Kierkegaard (1813 – 1855) was a Danish theologian, philosopher, poet, social critic, and religious author who is widely known as the father of existentialism. He focused on the individual’s subjective experience, emphasizing the importance of personal responsibility and authenticity. Kierkegaard’s works explore themes such as anxiety, faith, and the search for meaning in a world filled with uncertainty.

Some of his main works include “Either/Or,” a collection of essays examining different approaches to life and love; “Fear and Trembling,” which explores the story of Abraham and Isaac to examine the nature of faith; “The Sickness Unto Death,” which delves into the concept of despair and the human struggle for self-identity; and “Works of Love,” which discusses the nature and importance of Christian love. Other notable works by Kierkegaard include “Concluding Unscientific Postscript,” “The Concept of Anxiety,” and “Training in Christianity.”
