Søren Kierkegaard (1813-55) published an extraordinary number of works during his lifetime, but he left behind nearly as much unpublished writing, most of which consists of what are called his "journals and notebooks." Volume 3 of this 11-volume edition of includes Kierkegaard's extensive notes on lectures by the Danish theologian H. N. Clausen and by the German philosopher Schelling, as well as a great many other entries on philosophical, theological, and literary topics. In addition, the volume includes many personal reflections by Kierkegaard, notably those in which he provides an account of his love affair with Regine Olsen, his onetime fiancée.
