Knowing The Natural Law

Knowing the Natural Law traces the thought of Aquinas from an understanding of human nature to a knowledge of the human good, from there to an account of ought-statements, and finally to choice, which issues in human actions. The much discussed article on the precepts of the natural law (I-II, 94, 2) provides the framework for a natural law rooted in human nature and in speculative knowledge. Practical knowledge is itself threefold: potentially practical knowledge, virtually practical knowledge, and fully practical knowledge.

If there is any one author in the history of moral thought who has come to be associated with the idea of natural law, it is Saint Thomas Aquinas. Many things have been written about Aquinas's natural law teaching, and from many different perspectives. The aim of this book is to help see it from his own perspective. That is why the focus is metaphysical. Aquinas's whole moral doctrine is laden with metaphysics, and his natural law teaching especially so, because it is all about first principles. The book centers on how Aquinas thinks the first principles of practical reason, which for him are what make up natural law, function as laws. It is a controversial question, and the book engages a variety of readers of Aquinas, including Francisco Suarez, Jacques Maritain, prominent analytical philosophers, Straussians, and the initiators of the New Natural Law theory. Among the issues addressed are the relation between natural law and natural inclination, how far natural law depends on knowledge of human nature, what its obligatory force consists in, and, above all, how it is related to what for Aquinas is the first principle of all being, the divine will.

From Human Dignity to Natural Law shows how the whole of the natural law, as understood in the Aristotelian Thomistic tradition, is contained implicitly in human dignity. Human dignity means existing for one’s own good (the common good as well as one’s individual good), and not as a mere means to an alien good. But what is the true human good? This question is answered with a careful analysis of Aristotle’s definition of happiness. The natural law can then be understood as the precepts that guide us in achieving happiness. To show that human dignity is a reality in the nature of things and not a mere human invention, it is necessary to show that human beings exist by nature for the achievement of the properly human good in which happiness is found. This implies finality in nature. Since contemporary natural science does not recognize final causality, the book explains why living things, as least, must exist for a purpose and why the scientific method, as currently understood, is not able to deal with this question. These reflections will also enable us to respond to a common criticism of natural law theory: that it attempts to derive statements of what ought to be from statements about what is. After defining the natural law and relating it to human or positive law, Richard Berquist considers Aquinas’s formulation of the first principle of the natural law. It then discusses the love commandments to love God above all things and to love one’s neighbor as oneself as the first precepts of the natural law. Subsequent chapters are devoted to clarifying and defending natural law precepts concerned with the life issues, with sexual morality and marriage, and with fundamental natural rights. From Human Dignity to Natural Law concludes with a discussion of alternatives to the natural law.

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.

An introduction to natural law theory and a challenge to re-think current biblical scholarship on the topic. Levering establishes the relevance of a biblical worldview to the contemporary pursuit of a moral life and locates his argument in the context of the philosophical development of natural law theory from Cicero to Nietzsche.

Drawing upon the timeless wisdom of Thomas Aquinas, The Natural Law offers clear insights into perplexing ethical dilemmas. The compelling conclusions of Aquinas emerge through a critical examination of contemporary ethical frameworks including moral relativism, utilitarianism, and Machiavellian politics. In part one, which elucidates the core principles of natural law ethics, the reader will discover fundamental truths underpinning the concepts of right and wrong, which are rooted in the very fabric of our humanity. Part two navigates the ethics of harm, grappling with contentious issues such as capital punishment, just war, and self-defense, while at the same time addressing moral quandaries like sacrificing one life in order to save another. This section also resolves thorny practical questions surrounding human actions. How can we tell the difference between an action and its consequences? How do we determine exactly what it means to kill another person? Part three ventures into the intricacies of human societies. The reader will explore the importance of authority and rules in guiding social interactions, from the nurturing bonds of the family to the shifting complexities of political society. The principles examined will shed light upon controversial topics within sexual ethics, such as transgenderism, faithful spousal intimacy, and cloning. The Natural Law invites readers on an engaging journey of critical inquiry. By challenging prevailing assumptions and provoking self-reflection, it will reshape your understanding of ethics and human nature, ultimately revealing your role and purpose within the universe.

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.

In A Comparative Analysis of Cicero and Aquinas, Charles P. Nemeth investigates how, despite their differences, these two figures may be the most compatible brothers in ideas ever conceived in the theory of natural law. Looking to find common threads that run between the philosophies of these two great thinkers of the Classical and Medieval periods, this book aims to determine whether or not there exists a common ground whereby ethical debates and dilemmas can be evaluated. Does comparison between Cicero and Aquinas offer a new pathway for moral measure, based on defined and developed principles? Do they deliver certain moral and ethical principles for human life to which each agree? Instead of a polemical diatribe, comparison between Cicero and Aquinas may edify a method of compromise and afford a more or less restrictive series of judgements about ethical quandaries.

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.

To explore and evaluate the current revival, this volume brings together many of the foremost scholars on natural law. They examine the relation between Thomistic natural law and the larger philosophical and theological tradition. Furthermore, they assess the contemporary relevance of St. Thomas's natural law doctrine to current legal and political philosophy.
