Originally published in German in 1936, The Natural Law is the first work to clarify the differences between traditional natural law as represented in the writings of Cicero, Aquinas, and Hooker and the revolutionary doctrines of natural rights espoused by Hobbes, Locke, and Rousseau. Beginning with the legacies of Greek and Roman life and thought, Rommen traces the natural law tradition to its displacement by legal positivism and concludes with what the author calls "the reappearance" of natural law thought in more recent times. In seven chapters each Rommen explores "The History of the Idea of Natural Law" and "The Philosophy and Content of the Natural Law." In his introduction, Russell Hittinger places Rommen's work in the context of contemporary debate on the relevance of natural law to philosophical inquiry and constitutional interpretation. Heinrich Rommen (1897–1967) taught in Germany and England before concluding his distinguished scholarly career at Georgetown University. Russell Hittinger is William K. Warren Professor of Catholic Studies and Research Professor of Law at the University of Tulsa.

Is there such a thing as an objective law of morality? Natural law theorists maintain that there is, and Natural Law probes the history and implications of this powerful concept. Tracing the development of natural law from ancient times to the present, the book also examines the leading figures, transitions, and turning points in the idea's evolution, and brings a natural law approach to contemporary issues such as abortion, homosexuality, and assisted suicide.

The theory of natural law grounds human laws in the universal truths of God’s creation. Until very recently, lawyers in the Western tradition studied natural law as part of their training, and the task of the judicial system was to put its tenets into concrete form, building an edifice of positive law on natural law’s foundations. Although much has been written about natural law in theory, surprisingly little has been said about how it has shaped legal practice. Natural Law in Court asks how lawyers and judges made and interpreted natural law arguments in England, Europe, and the United States, from the beginning of the sixteenth century to the American Civil War. R. H. Helmholz sees a remarkable consistency in how English, Continental, and early American jurisprudence understood and applied natural law in cases ranging from family law and inheritance to criminal and commercial law. Despite differences in their judicial systems, natural law was treated across the board as the source of positive law, not its rival. The idea that no person should be condemned without a day in court, or that penalties should be proportional to the crime committed, or that self-preservation confers the right to protect oneself against attacks are valuable legal rules that originate in natural law. From a historical perspective, Helmholz concludes, natural law has advanced the cause of justice.

Presents a systematic, contemporary defence of the natural law outlook in ethics, politics and jurisprudence.

The "natural law" worldview developed over the course of almost two thousand years beginning with Plato and Aristotle and culminating with St. Thomas Aquinas in the thirteenth century. This tradition holds that the world is ordered, intelligible and good, that there are objective moral truths which we can know and that human beings can achieve true happiness only by following our inborn nature, which draws us toward our own perfection. Most accounts of the natural law are based on a God-centered understanding of the world. After the Natural Law traces this tradition from Plato and Aristotle to Thomas Aquinas and then describes how and why modern philosophers such as Descartes, Locke and Hobbes began to chip away at this foundation. The book argues that natural law is a necessary foundation for our most important moral and political values – freedom, human rights, equality, responsibility and human dignity, among others. Without a theory of natural law, these values lose their coherence: we literally cannot make sense of them given the assumptions of modern philosophy. Part I of the book traces the development of natural law theory from Plato and Aristotle through the crowning achievement of Thomas Aquinas. Part II explores how modern philosophers have systematically chipped away at the only coherent foundation for these values. As a result, our most important moral and political ideals today are incoherent. Modern political and moral thinkers have been led either to dilute the meaning of such terms as freedom or the moral good – or abandon these ideas altogether. Thus, modern philosophy and political thought are leading us either toward anarchy or totalitarianism. The conclusion, entitled "Why God Matters", shows how even the philosophical assumptions of the natural law depend on a personal God.

Author Alberto M. Piedra lucidly illustrates the notion of 'natural law' through the examination of economic, social, political, and cultural issues. In this work Piedra draws on classical and Christian sources as well as his personal experience as an economist, diplomat, and lecturer on world politics to address philosophical views in a constructive and morally guided exegesis of natural law and economics. This innovative book shows the value of appeals to a governing, natural law and attendant principles such as the common good, subsidiarity, hierarchy, spiritual welfare, the reciprocity of freedom and authority, and the cultivation of personal moral and intellectual virtue. Natural Law will appeal to scholars, professionals, and others interested in the cultivation of personal moral and intellectual virtue.

Has Hobbesian moral and political theory been fundamentally misinterpreted by most of his readers? Since the criticism of John Bramhall, Hobbes has generally been regarded as advancing a moral and political theory that is antithetical to classical natural law theory. Kody W. Cooper challenges this traditional interpretation of Hobbes in Thomas Hobbes and the Natural Law. Hobbes affirms two essential theses of classical natural law theory: the capacity of practical reason to grasp intelligible goods or reasons for action and the legally binding character of the practical requirements essential to the pursuit of human flourishing. Hobbes’s novel contribution lies principally in his formulation of a thin theory of the good. This book seeks to prove that Hobbes has more in common with the Aristotelian-Thomistic tradition of natural law philosophy than has been recognized. According to Cooper, Hobbes affirms a realistic philosophy as well as biblical revelation as the ground of his philosophical-theological anthropology and his moral and civil science. In addition, Cooper contends that Hobbes's thought, although transformative in important ways, also has important structural continuities with the Aristotelian-Thomistic tradition of practical reason, theology, social ontology, and law. What emerges from this study is a nuanced assessment of Hobbes’s place in the natural law tradition as a formulator of natural law liberalism. This book will appeal to political theorists and philosophers and be of particular interest to Hobbes scholars and natural law theorists.
