The Bioethical Compass: Navigating Contemporary Bioethics Hardcover – March 9, 2026

The Bioethical Compass: Navigating Contemporary Bioethics is a foundational work in contemporary bioethical reflection that argues bioethics must recover its normative character and return to objective moral truth. Rather than presenting bioethics as a neutral catalog of competing opinions, Diego Menniti defines it as a discipline ordered toward proclamation: the rational defense of enduring principles capable of guiding moral judgment in medicine, science, and public life. The book begins by examining what bioethics is, tracing its historical development from the Hippocratic tradition and Fritz Jahr to Van Rensselaer Potter, the Nuremberg Code, the Declaration of Helsinki, the Belmont Report, and the major technological and medical developments that shaped the modern field. It then argues that bioethics cannot remain merely descriptive or procedural, because questions involving life, death, conscience, dignity, and responsibility demand more than compromise or institutional consensus.From there, Menniti turns to the contemporary Ἀγορά (agora), the public square of bioethical debate, and critically engages the principal moral theories that shape modern discourse. The book examines cognitivist, consequentialist, and non-cognitivist approaches, along with the role of conscience, judged conscience, and the will in moral discernment. It also offers a sustained critique of relativism, ethical fragmentation, and the exclusion of religious reasoning from bioethical discussion. A central section of the volume studies the theory of principles, including autonomy, beneficence, non-maleficence, justice, paternalism, informed consent, relational autonomy, decisional capacity, and the limits of principlism in resolving ethical dilemmas. Throughout, Menniti argues that these principles become unstable when detached from a realistic anthropology and a coherent account of the human person.The culmination of the book is the proposal of Quantum Personalist Ethics, a new theoretical synthesis that brings together quantum science, metaphysical anthropology, and the Christian intellectual tradition. Drawing in part on Orchestrated Objective Reduction (Orch-OR), Menniti presents an account of the human person as ontologically singular, irreducible, and unrepeatable, and argues that authentic bioethics must be grounded in this deeper vision of human dignity.Importantly, this volume is primarily conceptual and methodological. As the introduction states, it intentionally refrains from offering direct solutions to the practical controversies of contemporary bioethics, reserving those applied analyses for a subsequent work. Its purpose is to establish the philosophical and anthropological foundations without which no serious bioethical judgment can endure. Written for readers interested in bioethics, moral philosophy, theology, medicine, and the foundations of human dignity, The Bioethical Compass is a rigorous invitation to rethink the discipline from its roots and to recover a moral framework capable of resisting relativism, proceduralism, and reductionism.
