The plan of this study is founded on a hypothesis that there is an overall argument in the Climacus writings (and reflected and supported in Kierkegaard's private papers and other writings): 1) There are two opposing ways to approach the truth: the objective and the subjective ways, 2) The objective way fails, 3) Hence the only appropriate way to the truth is the subjective way, 4) Christianity is the subjective way of life that meets all conditions for the highest subjectivity, 5) Hence Christianity is the appropriate way to reach the truth. The present work is sympathetically critical - always appreciative of Kierkegaard's genius but not always endorsing his arguments.
