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.
Phyllis Greenacre
In an early publication from 1939, Greenacre explored the role of a severe sense of (unconscious) guilt in fueling surgical addiction. Two years later she published her once controversial but now classic study of childhood anxiety as manifested preverbally.
