In the introduction, I noted that various themes weave in and out of Kierkegaard’s corpus. The most pervasive of these themes is the inwardness of the single individual. As previously mentioned, Kierkegaard wished that “that single individual” would be his headstone epitaph. As significant as this concept is, there are two reasons for not dedicating a chapter to the topic. First, the theme is best understood in its relationship with other Kierkegaardian concepts. Though the Chap. 2 of this volume was the most concentrated treatment of the single individual, it could not address the topic comprehensively. That chapter addressed the topic in isolation to itself and not to the other major concepts in Kierkegaard’s works.
