This volume of original essays addresses a range of issues concerning the responsibility individuals have for their actions and for their characters. Among the central questions considered are the following: What scope is there for regarding a person as responsible for his or her character given genetic and environmental factors? Does an account of responsibility provide a legitimate basis for the retributive emotions? Are we ever justified in feeling guilty for occurences over which we have no control? Does responsibility for the consequences of our acts require that they were intended or simply expected? How have a number of influential previous philosophers, including Aristotle, Maimonides, and Spinoza, approached these questions?
