Oxford Studies in Agency and Responsibility is a series of volumes presenting outstanding new work on a set of connected themes, investigating such questions as: * What does it mean to be an agent? * What is the nature of moral responsibility? Of criminal responsibility? What is the relation between moral and criminal responsibility (if any)? * What is the relation between responsibility and the metaphysical issues of determinism and free will? * What do various psychological disorders tell us about agency and responsibility? * How do moral agents develop? How does this developmental story bear on questions about the nature of moral judgment and responsibility? * What do the results from neuroscience imply (if anything) for our questions about agency and responsibility? No one has written more insightfully on the promises and perils of human agency than Gary Watson, who has spent a career thinking about issues such as moral responsibility, blame, free will, weakness of will, addiction, and psychopathy. This special edition of OSAR pays tribute to Watson's work by taking up and extending themes from his pioneering essays.
