Oxford Studies in Agency and Responsibility is a series of volumes presenting outstanding new work on a set of connected themes in moral philosophy and philosophy of action. This special volume in the series presents ten new papers marking the fiftieth anniversary of P. F. Strawson's landmark essay, 'Freedom and Resentment'. Some of the papers offer critical interpretation of Strawson's essay, some expand on his insights into the nature of interpersonal relationships, and some develop his overall themes in new and challenging directions.
