Natural law, according to Thomas Aquinas, has its foundation in the evidence and operation of natural, human reason. Its primary precepts are self-evident. Awareness of these precepts does not presuppose knowledge of, or even belief in, the existence of God. The most interesting criticisms of Thomas Aquinas’s natural-law teaching in modern times have been advanced by the political philosopher Leo Strauss and his followers. The purpose of this book is to show that these criticisms are based on misunderstandings and that they are inconclusive at best. Thomas Aquinas’s natural-law teaching is fully rational. It is accessible to man as man.

"Public reason" is one of the central concepts in modern liberal political theory. As articulated by John Rawls, it presents a way to overcome the difficulties created by intractable differences among citizens' religious and moral beliefs by strictly confining the place of such convictions in the public sphere. Identifying this conception as a key point of conflict, this book presents a debate among contemporary natural law and liberal political theorists on the definition and validity of the idea of public reason. Its distinguished contributors examine the consequences of interpreting public reason more broadly as "right reason," according to natural law theory, versus understanding it in the narrower sense in which Rawls intended. They test public reason by examining its implications for current issues, confronting the questions of abortion and slavery and matters relating to citizenship. This energetic exchange advances our understanding of both Rawls's contribution to political philosophy and the lasting relevance of natural law. It provides new insights into crucial issues facing society today as it points to new ways of thinking about political theory and practice.

Is knowledge of right and wrong written on the human heart? Do people know God from the world around them? Does natural knowledge contribute to Christian doctrine? While these questions of natural theology and natural law have historically been part of theological reflection, the radical reliance of twentieth-century Protestant theologians on revelation has eclipsed this historic connection. Stephen Grabill attempts the treacherous task of reintegrating Reformed Protestant theology with natural law by appealing to Reformation-era theologians such as John Calvin, Peter Martyr Vermigli, Johannes Althusius, and Francis Turretin, who carried over and refined the traditional understanding of this key doctrine. Rediscovering the Natural Law in Reformed Theological Ethics calls Christian ethicists, theologians, and laypersons to take another look at this vital element in the history of Christian ethical thought.

This edited volume examines the realizations between theological considerations and natural law theorizing, from Plato to Spinoza. Theological considerations have long had a pronounced role in Catholic natural law theories, but have not been as thoroughly examined from a wider perspective. The contributors to this volume take a more inclusive view of the relation between conceptions of natural law and theistic claims and principles. They do not jointly defend one particular thematic claim, but articulate diverse ways in which natural law has both been understood and related to theistic claims. In addition to exploring Plato and the Stoics, the volume also looks at medieval Jewish thought, the thought of Aquinas, Scotus, and Ockham, and the ways in which Spinoza's thought includes resonances of earlier views and intimations of later developments. Taken as a whole, these essays enlarge the scope of the discussion of natural law through study of how the naturalness of natural law has often been related to theses about the divine. The latter are often crucial elements of natural law theorizing, having an integral role in accounting for the metaethical status and ethical bindingness of natural law. At the same time, the question of the relation between natural law and God-and the relation between natural law and divine command-has been addressed in a multiplicity of ways by key figures throughout the history of natural law theorizing, and these essays accord them the explanatory significance they deserve.

This noteworthy book develops a new theory of the natural law that takes its orientation from the account of the natural law developed by Thomas Aquinas, as interpreted and supplemented in the context of scholastic theology in the twelfth and thirteenth centuries. Though this history might seem irrelevant to twenty-first-century life, Jean Porter shows that the scholastic approach to the natural law still has much to contribute to the contemporary discussion of Christian ethics. Aquinas and his interlocutors provide a way of thinking about the natural law that is distinctively theological while at the same time remaining open to other intellectual perspectives, including those of science. In the course of her work, Porter examines the scholastics' assumptions and beliefs about nature, Aquinas's account of happiness, and the overarching claim that reason can generate moral norms. Ultimately, Porter argues that a Thomistic theory of the natural law is well suited to provide a starting point for developing a more nuanced account of the relationship between specific beliefs and practices. While Aquinas's approach to the natural law may not provide a system of ethical norms that is both universally compelling and detailed enough to be practical, it does offer something that is arguably more valuable -- namely, a way of reflecting theologically on the phenomenon of human morality.

This book proposes a rather novel legal-philosophical approach to understanding the intersection between law and morality. It does so by analyzing the conditions for the existence of a juridical domain of natural law from the perspective of the tradition of Thomistic juridical realism. In order to highlight the need to reconnect with this tradition in the context of contemporary legal philosophy, the book presents various other recent jurisprudential positions regarding the overlap between law and morality. While most authors either exclude a conceptual necessity for the inclusion of moral principles in the nature of law or refer to the purely moral status of natural law at the foundations of the legal phenomenon, the book seeks to elucidate the essential properties of the juridical status of natural law. In order to establish the juridicity of natural law, the book explores the relevant arguments of Thomas Aquinas and some of his main commentators on this issue, above all Michel Villey and Javier Hervada. It establishes that Thomistic juridical realism observes the juridical phenomenon not only from the perspective of legal norms or subjective individual rights, but also from the perspective of the primary meaning of the concept of right (ius), namely, the just thing itself as the object of justice. In this perspective, natural rights already possess a fully juridical status and can be described as natural juridical goods. In addition, from the viewpoint of Thomistic juridical realism, we can identify certain natural norms or principles of justice as the juridical title of these rights or goods. The book includes an assessment of the prospective points of dialogue with the other trends in Thomistic legal philosophy as well as with various accounts of the nature of law in contemporary legal theory.

This first English translation of Pierre Manent’s profound and strikingly original book La loi naturelle et les droits de l’homme is a reflection on the central question of the Western political tradition. In six chapters, developed from the prestigious Étienne Gilson lectures at the Institut Catholique de Paris, and in a related appendix, Manent contemplates the steady displacement of the natural law by the modern conception of human rights. He aims to restore the grammar of moral and political action, and thus the possibility of an authentically political order that is fully compatible with liberty. Manent boldly confronts the prejudices and dogmas of those who have repudiated the classical and Christian notion of “liberty under law” and in the process shows how groundless many contemporary appeals to human rights turn out to be. Manent denies that we can generate obligations from a condition of what Locke, Hobbes, and Rousseau call the “state of nature,” where human beings are absolutely free, with no obligations to others. In his view, our ever-more-imperial affirmation of human rights needs to be reintegrated into what he calls an “archic” understanding of human and political existence, where law and obligation are inherent in liberty and meaningful human action. Otherwise we are bound to act thoughtlessly and in an increasingly arbitrary or willful manner. Natural Law and Human Rights will engage students and scholars of politics, philosophy, and religion, and will captivate sophisticated readers who are interested in the question of how we might reconfigure our knowledge of, and talk with one another about, politics.
