Book excerpt: The Routledge Handbook of the Philosophy and Psychology of Forgiveness brings into conversation research from multiple disciplines, offering readers a comprehensive guide to current forgiveness research. Its 42 chapters, newly commissioned from an internationally acclaimed group of scholars, are divided into five parts: Religious Traditions Historic Treatments The Nature of Forgiveness Normative Issues Empirical Findings While the principal aim of the handbook is to provide a guide to the philosophical literature on forgiveness that, ideally, will inform the psychological sciences in developing more philosophically accurate measures and psychological treatments of forgiveness, the volume will be of interest to students and researchers with a wide range of disciplinary backgrounds, including philosophy, psychology, theology, religious studies, classics, history, politics, law, and education.
