Augustine (354-430) is a central figure in European intellectual history and the Christian adaptation of ancient philosophy. His teachings on original sin, predestination, and grace have had a significant cultural impact—philosophically speaking, they are a scandal. Johann Kreuzer's introduction does not overlook this dark aspect of Augustine's thought but instead focuses on the analyses found in his major works "Confessions," "On the Trinity," and "The City of God." This makes it clear which themes have turned Augustine's work into a productive site of unrest in the history of European thought. Not least, his insight into the irretrievability of lived existence makes him a relevant interlocutor for the present.
