RT Article T1 Überpolarität: der Glaube an ein absolutes Du bei Karl Heim JF Kerygma und Dogma VO 62 IS 3 SP 248 OP 268 A1 Sass, Hartmut von 1980- LA German YR 2016 UL https://ixtheo.de/Record/1635976189 AB Karl Heim’s work has been best known for relating science to religion - and is now almost forgotten due to unavoidable impasses within Heim’s metaphysics. Nevertheless, in the midst of these aporias one finds intriguing considerations regarding the concept of faith and the act of conversion. In a threefold argument the paper considers both the critical and the fruitful elements in Heim’s approach: first, it locates more precisely the heartbeat of Heim’s theology by relating it to Dialectic Theology; second, it clarifies in which sense Heim confronts us with an unhappy duality between absolute certainty and a helpless relativism, where contemporary science leads to the latter alternative; third, it shows how Heim defends religion as a framework that solely provides that very certainty. By doing that, Heim elaborates on the act of coming to believe and, hence, a religious perspectivism that is - beyond his own intentions - fruitfully provocative for theology today.
