This is an introduction to the influence of Kierkegaard's thought on the development of modern theology. Kierkegaard is in many respects an enigmatic figure. About half of his published work appears under an array of pseudonyms and Kierkegaard himself advises that readers should not presume his agreement with any of the views appearing under pseudonymous authorship. Alongside the pseudonymous works are a long series of discourses published under Kierkegaard's own name, and accompanying the whole corpus are six volumes of Journals in which Kierkegaard experiments with ideas and makes note of his own questions and discoveries. Kierkegaard's concern throughout the authorship was to make clear, in opposition to the corrosive forces of Christendom and the posturing of contemporary philosophy, what authentic Christian faith consists in. "The Philosophy and Theology Series" looks at major philosophers and explores their relevance to theological thought as well as the response of theology.
