This volume investigates the foundational questions of ethics by curating original philosophical research that bridges the gap between metaethics and related disciplines. Editor Russ Shafer-Landau compiles peer-reviewed essays that address the nature of moral properties, the semantics of moral language, and the epistemological status of ethical beliefs. The work serves as a primary record of the evolving discourse within the field of moral philosophy.

Experts and academics recognize this series as a primary venue for high-level discourse in metaethics. Readers frequently note the technical density of the prose, which is intended for professional philosophers and advanced graduate students.
