This modern reason will learn to understand itself only when it clarifies its relation to contemporary religious consciousness which has become reflexive by grasping the shared origin of two complementary intellectual formations in cognitive advance of Axial Age. In speaking of complementary intellectual formations, I am expressly rejecting two positions: first, the blinkered enlightenment which is unenlightened about itself and which denies religion any rational content, but also, second, Hegel’s view for which religion represents an intellectual formation worthy of being recalled, but only in the form of “representational thinking” which is subordinate to philosophy. Faith remains opaque for knowledge in a way which may neither be denied nor simply accepted. This reflects the inconclusive nature of the confrontation between a self-critical reason which is willing to learn and contemporary religious convictions. This confrontation can sharpen post-secular society’s awareness of the unexhausted force of religious traditions. Secularisation functions less as a filter separating out the contents of traditions than as a transformer which redirects the flow of tradition.
