The nineteenth-century Danish philosopher Søren Kierkegaard (1813-1855) is well known as the father of existentialism and one of the great Christian thinkers of all time. But it is in his relationship with Regine Olsen - his love for her, their brief engagement, and the horrible breakup, in which he left her for a life devoted to the pursuit of knowledge - where we see his true literary gifts. In this episode, Jacke looks at Kierkegaard's life and writing, with a special focus on the agonizing relationship with a young woman that perhaps brought out his truest self.
