Abstract
After having briefly discussed the question of whether Kierkegaard can be considered as a “philosopher of religion,” this chapter deals with three classic topics of religious philosophy: faith and reason; the existence of God; and the immortality of the soul. As regards the first question, an attempt will be made to show that Kierkegaard's position is not a kind of theological gnoseology, but an original kind of existential philosophy. It will be pointed out that although reason is a negative condition for faith, still faith is in no way a kind of knowledge, but a proper way of existence. Regarding the second issue, Kierkegaard's apophatical theology and his argumentation against traditional natural theology will be treated in connection with the general problem of the (un)demonstrability of existential assertions. Finally, the chapter will outline that, for Kierkegaard, immortality is not a metaphysical quality of the soul, but an existential possibility that is closely connected with becoming a self of an existing individual.
