The Danish philosopher, theologian, and author Soren Kierkegaard is widely considered to be one of the most important and wide-ranging religious thinkers of the modern age. He is known as the father of existentialism, but his work was also influential on theories of modernism, theology, Western culture, church politics, and the Christian faith. His wit, imagination and humor have inspired a generation of followers, from Woody Allen to Franz Kafka. But how did this inattentive schoolboy rise to critique the work of great thinkers such as Hegel and the German romantics? Who was the real (and unusual) person writing behind so many pseudonyms? And in what way are Kierkegaard’s concepts still relevant today?In this absorbing new biography, Alastair Hannay unravels the mystery of Sren Kierkegaard’s short but momentous career. Looking at both Kierkegaard the thinker and the person, Hannay describes this controversial figure’s key concepts and major works alongside the major incidents in his private and public life. From Kierkegaard’s longing for selfhood as expressed at the age of twenty-two, to a self-provoked spat with a satirical weekly that has caused him to be caricatured to this day, to a verbal assault on the Church in the months prior to his early death at the age of forty-two, Sren Kierkegaard is the fascinating story of a man destined to become a thorn in the side of society.
