The Concept of Anxiety
All of Kierkegaard's books have either a preface, dedication, or prayer at the beginning. This book includes a lengthy introduction. "The Concept of Anxiety" was published on exactly the same date as "Prefaces", June 17, 1844. Both books deal with Hegel’s idea of mediation. Mediation is a common thread throughout Kierkegaard’s works. His work up to this point was to show that faith was being mediated by knowledge. Here he takes up the questions of sin and guilt.
Two Minor Ethical-Religious Essays
Two Minor Ethical-Religious Essays (original Danish title: "Tvende ethisk-religieuse Smaa-Afhandlinger") is a work by the Danish philosopher Søren Kierkegaard, under the pseudonym H.H., written in 1847 and published on May 19, 1849. Kierkegaard wrote a book entitled "A Cycle of Ethical-Religious Essays" but chose to publish these two essays as a separate piece while leaving the rest unpublished. The unpublished work would eventually become "The Book on Adler". The work is in dual authorship with his signed work "Upbuilding Discourses in Various Spirits", also completed in 1847.
