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: what scope is there for regarding a person as responsible for his character given genetic and environmental factors; does an account of responsiblity provide a legitimate basis for the retributive emotions; are we ever justified in feeling guilty for occurrences over which we have no control; does responsibility for the consequences of our acts require that they were intended or simply expected; and how have a number of influential previous philosophers, including Aristotle, Maimonides, and Spinoza, approached these questions?
