In this work, Sullivan analyzes the relationship between faith and reason in Kierkegaard's philosophy. Kierkegaard is widely considered to be an irrationalist. Sullivan argues that he views faith as reasonable in a distinct way that must be uncovered. In some of his pseudonymous works, Kierkegaard speaks of the movement of faith as paradoxical and absurd. There is evidence from his non-pseudonymous works that Kierkgaard does not consider faith irrational.
