In this multi-disciplinary collection we ask the question, 'What did, and do, Quakers think about good and evil?' There are no simple or straightforwardly uniform answers to this, but in this collection, we draw together contributions that for the first time look at historical and contemporary Quakerdom's approach to the ethical and theological problem of evil and good. Within Quakerism can be found Liberal, Conservative, and Evangelical forms. This book uncovers the complex development of metaethical thought by a religious group that has evolved with an unusual degree of diversity. In doing so, it also points beyond the boundaries of the Religious Society of Friends to engage with the spectrum of thinking in the wider religious world.
