What is the origin of evil? Where does what we term evil come from? According to Paul Ricoeur, to think through evil is to think through fallibility; because human freedom is summed up as existence prior to evil. Deriving from a lecture given in Lausanne in 1985, this small text adds to the immense ouevre of this philosopher who is not regarded as a theologian but whose thinking readily shares some kinship with certain characteristics of Protestantism. The problem of evil was a question which dogged Paul Ricoeur throughout his reflection and his philosophical works. This is a man who has thought about vulnerability in moral evil with both an exemplary profundity and sensitivity. "Evil: A Challenge to Philosophy and Theology" contains a new extended introduction by Graham Ward which reflects on the significance of Paul Ricoeur's approach to philosophy and to the question of evil for 20th-century theology and philosophy, and a preface by Pierre Gisel.
