Foundations of Criminal Law presents a comprehensive examination of the general part of criminal law -- that is, the foundational elements of liability -- through interdisciplinary readings drawn primarily from law, philosophy, and the behavioral sciences. The selections range from classical treatments to contemporary approaches, and the topics include -- among others -- theories of punishment, mental states, causation, justification and excuse, and sentencing. A general introduction precedes each section and the readings are followed by comments and questions designed to engage the reader analytically.
