This work challenges the textbook assessment of Schopenhauer as militant atheist and absolute pessimist. In examining Schopenhauer’s grappling with religion, theology and Kant’s moral philosophy, Mannion suggests we can actually discern a ’religious’ humility in method in Schopenhauer’s work, seen most clearly in his ethics of compassion and his doctrine of salvation. Given current debates between theologians and philosophers in relation to ’postmodernity’ and ’postmodern thought’, this book illustrates that Schopenhauer should be a key figure in such debates.
