The Concept of Anxiety: A Simple Psychologically Orienting Deliberation on the Dogmatic Issue of Hereditary Sin is often considered Kierkegaard’s most difficult work.

The following may not make any sense (as I am trying to sort this out myself) but I thought I would try and unpack a few key quotes in Kierkegaard’s concept.
