The question of truth, one of the oldest challenges in theological thinking, is at the center of the partly new, partly revised studies in this volume. It gets its special accentuation through the encounter of theology with the analytical philosophy of religion and the dialogue with contemporary natural science. The author advocates enduring the mutual imposition of this not conflict-free encounter instead of looking for simple solution formulas. For this reason, he also includes classic answer models, such as Karl Barth's theological approach or the theory of metaphors, in his considerations. Exemplary problem areas illustrate the possibilities and limits of interdisciplinary communication.
