The study of ethics is primarily associated with questions of morality: “good” and “bad,” “right” and “wrong.” The field of metaethics asks about what we mean by terms like “good” or “right,” and whether they represent real features of the world.

In Metaethics: A Short Companion, David A. Horner and J. P. Moreland provide a primer on how to think about questions surrounding the concept of morality—its nature, status, grounding, underlying presuppositions, and philosophical commitments. From a stance rooted in moral realism, Horner and Moreland explore and evaluate the major metaethical positions on offer in the field, including expressivism, error theory, relativism, constructivism, ethical naturalism, and ethical nonnaturalism. They conclude by arguing for the rationality of a Christian worldview as a guiding metaethical position.

The study of metaethics equips Christians to think deeply about the nature of reality, knowledge, truth, and morality. Metaethics: A Short Companion offers a clear and concise introduction to the key concepts and debates in metaethics, providing readers with a foundation for reflecting on their own ethical beliefs and practices.

The Essentials in Christian Ethics series, edited by C. Ben Mitchell and Jason Thacker, is designed to illuminate the richness and centrality of ethics to all of the Christian life. The series consists of short, introductory volumes written by renowned scholars in the fields of ethics, theology, and philosophy. Each volume explores a crucial element of Christian ethical reflection, approaching the subject from within the broader Protestant moral tradition.
