In this comprehensive anthology, twenty-seven outstanding scholars from North America and Europe address every major aspect of Thomas Aquinas's understanding of morality and comment on his remarkable legacy. While there has been a revival of interest in recent years in the ethics of St. Thomas, no single work has yet fully examined the basic moral arguments and content of Aquinas' major moral work, the Second Part of the Summa Theologiae. This work fills that lacuna.

The first chapters of The Ethics of Aquinas introduce readers to the sources, methods, and major themes of Aquinas's ethics. The second part of the book provides an extended discussion of ideas in the Second Part of the Summa Theologiae, in which contributors present cogent interpretations of the structure, major arguments, and themes of each of the treatises. The third and final part examines aspects of Thomistic ethics in the twentieth century and beyond.

These essays reflect a diverse group of scholars representing a variety of intellectual perspectives. Contributors span numerous fields of study, including intellectual history, medieval studies, moral philosophy, religious ethics, and moral theology. This remarkable variety underscores how interpretations of Thomas's ethics continue to develop and evolve—and stimulate fervent discussion within the academy and the church.

This volume is aimed at scholars, students, clergy, and all those who continue to find Aquinas a rich source of moral insight.

Moral theologians, defense analysts, conflict scholars, and nuclear experts imagine a world free from nuclear weapons

At a 2017 Vatican conference, Pope Francis condemned nuclear weapons. This volume, issued after the 60th anniversary of the Cuban Missile Crisis, presents essays from moral theologians, defense analysts, conflict transformation scholars, and nuclear arms control experts, with testimonies from witnesses. It is a companion volume to A World Free from Nuclear Weapons: The Vatican Conference on Disarmament (Georgetown University Press, 2020).

Chapters from the perspectives of missile personnel and the military chain of command, industrialists and legislators, and citizen activists show how we might achieve a nuclear-free world. Key to this transition is the important role of public education and the mobilization of lay movements to raise awareness and effect change. This essential collection prepares military professionals, policymakers, everyday citizens, and the pastoral workers who guide them, to make decisions that will lead us to disarmament.

The just war tradition is central to the practice of international relations, in questions of war, peace, and the conduct of war in the contemporary world, but surprisingly few scholars have questioned the authority of the tradition as a source of moral guidance for modern statecraft. Just War: Authority, Tradition, and Practice brings together many of the most important contemporary writers on just war to consider questions of authority surrounding the just war tradition.

Authority is critical in two key senses. First, it is central to framing the ethical debate about the justice or injustice of war, raising questions about the universality of just war and the tradition’s relationship to religion, law, and democracy. Second, who has the legitimate authority to make just-war claims and declare and prosecute war? Such authority has traditionally been located in the sovereign state, but non-state and supra-state claims to legitimate authority have become increasingly important over the last twenty years as the just war tradition has been used to think about multilateral military operations, terrorism, guerrilla warfare, and sub-state violence. The chapters in this collection, organized around these two dimensions, offer a compelling reassessment of the authority issue’s centrality in how we can, do, and ought to think about war in contemporary global politics.

What does Aquinas have to teach us on the topic of peace? Looking over the scholarly literature, one would think very little. Most Thomists ignore Aquinas’s thought on peace. Most peace researchers summarily dismiss Aquinas. Peace in the Thought of Thomas Aquinas challenges both these trends and offers the first book length study of peace in Aquinas’s thought. John Meinert outlines Aquinas's historical predecessors, then provides an exposition and interpretation of the full scope of Aquinas's thought on peace: metaphysics, Trinitarian theology, Christology, Pneumatology, ecclesiology, natural theology, ethics, and sacramental theology. What emerges from this extended study is a new vision of Aquinas’s work. Peace in the Thought of Thomas Aquinas establishes Aquinas as an indispensable dialogue partner for anyone thinking rigorously about the theology, philosophy, and ethics of peace. As Aquinas himself says, “observe peace and you will come to salvation.”
