This volume investigates the foundational theoretical framework of moral philosophy, specifically addressing the objectivity and rationality of ethical discourse. R. M. Hare, a prominent figure in 20th-century analytic philosophy, compiles a series of essays that articulate his meta-ethical positions. By examining the tension between ethical realism and opposing schools of thought, the author provides a rigorous defense of his prescriptive approach to moral reasoning.

Experts recognize this collection as a critical resource for understanding Hare's broader philosophical system and his contributions to meta-ethics. Readers frequently note the academic density of the prose, which serves as a foundational text for students and scholars of moral philosophy.
