Most philosophical explorations of responsibility discuss the topic solely in terms of metaphysics and the "free will" problem. By contrast, these essays by leading philosophers view responsibility from a variety of perspectives - metaphysics, ethics, action theory, and the philosophy of law. After a broad, framing introduction by the volume's editors, the contributors consider such subjects as responsibility as it relates to the "free will" problem; the relation between responsibility and knowledge or ignorance; the relation between causal and moral responsibility; the difference, if any, between responsibility for actions and responsibility for omissions; the metaphysical requirements for making sense of "collective" responsibility; and the relation between moral and legal responsibility. The contributors include such distinguished authors as Alfred R. Mele, John Martin Fischer, George Sher, and Frances Kamm, as well as important rising scholars. Taken together, the essays in Action, Ethics, and Responsibility offer a breadth of perspectives that is unmatched by other treatments of the topic.
