Natural Law Theory

In this paper I argue that differences between the ‘new moral science’ of the seventeenth century and scholastic natural law theory originated primarily from the skeptical challenge the former had to face. Pufendorf’s project of a scientia practica universalis is the paramount expression of an anti-skeptical moral science, a ‘science’ that is both explanatory and normative, but also anti-dogmatic insofar as it tries to base its laws on those basic phenomena of human life which, supposedly, are immune to skeptical doubt. (...) The main scholastic legacy to the new moral science is the dichotomy between an ‘intellectualist’ and a ‘voluntarist’ view of natural law (or between lex immanens and lex imposita). Voluntarism lies at the basis of both theological views, such as Calvinism, and political views, such as those of Hobbes and Locke. The need to counterbalance the undesirable implications of extreme voluntarism may account for much of the developments in ethics and politics during the seventeenth and eighteenth centuries.Scottish natural jurisprudence, which tried to find a middle way between skepticism and extreme voluntarism, is less secular and more empirical than received wisdom admits. There emerged, as one of its ‘accidental’ outcomes, a systematic, self-contained and empirical economic theory from the search for an empirically based normative theory of social life. The basic assumption of such a theory, namely, the notion of societal laws as embedded in trans-individual mechanisms, derives from the voluntarist view of natural law as ‘imposed’ law.Later discussions of social issues in terms of ‘economic’ and ‘ethical’ reasons originated partly from a misreading ofthe Scottish natural jurisprudential framework of economic theory. Starting with this reconstruction, I try to shed some light on recent discussions about the role of ethics in economics. (shrink)

The law presents itself as a body of meaning, open to discovery, interpretation, application, criticism, development and change. But what sort of meaning does the law possess? Legal theory provides three sorts of answers. The first portrays the law as a mode of communication through which law-makers convey certain standards or norms to the larger community. The law's meaning is that imparted by its authors. On this view, law is a vehicle, conveying a message from a speaker to an intended (...) audience. The second theory portrays the law as a mode of interpretation, whereby judges, officials, and ordinary citizens make decisions about how the law applies in various practical contexts. The law's meaning is that furnished by its interpreters. According to this theory, law is a receptacle into which decision-makers pour meaning. The third viewpoint argues that these theories, while not altogether wrong, are incomplete because they downplay or ignore the autonomous meaning that the law itself possesses. This theory suggests that the law is basically a mode of participation, whereby legislators, judges, officials, and ordinary people attune themselves to an autonomous field of legal meaning. The law's meaning is grounded in a body of social practice which is independent of both the law's authors and its interpreters and which is infused with basic values and principles that transcend the practice. On this view, law is the emblem of meaning that lies beyond it. -/- Elements of all three theories are present in H.L.A. Hart's influential work, The Concept of Law, which attempts to fuse them into a single, all-encompassing theory. Nevertheless, as we will argue here, the attempt is not successful. Any true reconciliation of the communication and interpretation theories can only take place within the framework of a fully developed participation theory. In the early stages of his work, Hart lays the foundation for such a theory. However, his failure to elaborate it in a thoroughgoing way renders the work incomplete and ultimately unbalanced. As we will see, there is something to be learned from this failure. (shrink)

It is often thought that the meaning of a legal provision must reside in the minds of its authors or its interpreters, or a combination of the two. Indeed, the point may seem so obvious that it scarcely needs any justification. Is there any sense, then, in the claim sometimes made by judges that a law has a meaning of its own, one that is distinct from the intentions of authors and interpreters alike? At first sight, the claim appears extravagant (...) and self-serving. However, there is more to it than meets the eye. Drawing on an example from the world of games, this essay argues that the law makes up a “participatory order of meaning,” an autonomous order to which legal drafters and interpreters bend their minds as they create particular patterns of meaning. Ultimately, a legal order should be understood as a concrete instance of a transcendent order of justice and basic values, which in some sense lies both within and beyond the laws of a particular time and place.

En el debate ético contemporáneo coexisten planteamientos derivados de la filosofía moral moderna con otros enfoques que cuestionan sus ambiciones normativas. Estos enfoques se han descrito como “éticas sin moral”, dando por sentado que el término “moral” recoge un aspecto nuclear del pensamiento ético moderno: el deseo de identificar las normas universales objetivas. En este ensayo me propongo examinar si es posible defender la normatividad de la razón sustrayéndose a las críticas esgrimidas desde las contemporáneas éticas sin moral.

Law being a derivative feature of reality, it exists in virtue of more fundamental things, upon which it depends. This raises the question of what is the relation of dependence that holds between law and its more basic determinants. The primary aim of this paper is to argue that grounding is that relation. We first make a positive case for this claim, and then we defend it from the potential objection that the relevant relation is rather rational determination (Greenberg 2004, (...) 2006). Against this challenge, we argue that the apparent objection is really no objection, for on its best understanding, rational determination turns out to actually be grounding. Finally, we clarify the framework for theories on law-determination that results from embracing our view; by way of illustration, we offer a ground-theoretic interpretation of Hartian positivism, and show how it can defuse an influential challenge to simple positivist accounts of law.

This book is the first comprehensive study of Plato’s conception of justice. The universality of human rights and the universality of human dignity, which is recognised as their source, are among the crucial philosophical problems in modern-day legal orders and in contemporary culture in general. If dignity is genuinely universal, then human beings also possessed it in ancient times. Plato not only perceived human dignity, but a recognition of dignity is also visible in his conception of justice, which forms the (...) core of his philosophy. Plato’s Republic is consistently interpreted here as a treatise on justice, relating to an individual and not to the state. The famous myth of the cave is a story about education taking place in the world here and now. The best activity is not contemplation, but acting for the benefit of others. Not ideas, but individuals are the proper objects of love. Plato’s philosophy may provide foundations for modern-day human rights protection rather than for totalitarian orders. (shrink)

Anthony Celano argues that after Thomas Aquinas the flexibility of Aristotle’s ethics gives way to the universal codes of Christian morality. His argument posits that the Schoolmen adopted a line of moral reasoning that follows a Platonic tradition of taking universal moral principles as the basis of moral reasoning. While Thomas does work in a tradition that, resemblant of the Platonic tradition, incorporates inerrant principles of moral reasoning in the habit of _synderesis_, his understanding of those principles is distinctly Aristotelian (...) in character and thus the flexible moral reasoning of Aristotle’s _phronimos_ is retained. For Thomas _synderesis_ is the first principle of practical reason and is the source rather than the inhibitor of personal and spontaneous moral reasoning. This article will first outline Celano’s position, detail the thought of Thomas’ predecessors, and then show how Thomas employs the principle of _synderesis_ in a distinctly Aristotelian framework.

The 19th Century New England author Thoreau provides an approach to conscience and unjust laws approximating that given by St. Thomas Aquinas in _Summa Theologiae_. But the portrait of conscience given by Thoreau in the 1848 oration “Civil Disobedience” is incomplete. Thoreau’s approach is solved by accepting insights given in Part I and Part I–II of _Summa Theologiae_. Allowing St. Thomas’ insights requires reform of Thoreau’s civil disobedience and conscientious objection. But Thoreau’s arguments are given new life.

John Finnis says that central cases of the concepts of social theory (such as the concept of law) fully instantiate certain characteristic values (which are instantiated in more-or-less watered-down ways in peripheral cases). Yet the instances of some such concepts (such as the concepts of slavery, of tyranny, and of murder) do not instantiate any value. I propose a solution to this puzzle: the central cases of such concepts focally instantiate certain ills. The central case of a concept essential to (...) social theory may excel in some specific good or in some specific ill, or in neither, or in both. What about law? The central cases of a legal system, or of a law, involve goods that Finnis ascribes to them; I argue that the central cases also involve certain ills. That is the irony of law. Law secures essential goods for a community, and also (and, in fact, by the same token) it incurs certain ills that are necessarily involved in its specific techniques for securing those goods.

I address four questions that arise out of Nigel Simmonds's book, Law as a Moral Idea : Is politics a moral idea too? Is there any such thing as law making? Is there a right answer to every legal dispute? What justifies a judicial decision? To each question I propose an answer that shares much with Simmonds's views, but diverges. Simmonds is right to call law a 'moral idea', and that implies a connection between law and a moral ideal; in (...) my view, the connection is compatible with a necessary connection between law and the morally non-ideal.

In his debate with H.L.A. Hart, Lon L. Fuller criticizes legal positivism for its inability to account for the moral obligation to obey the law, an obligation in which he and, he thinks, most others, including legal positivists, believe. He assumes that his alternative conception of law is not similarly flawed. In this paper, I ask whether his assumption is warranted. My topic, therefore, is Fuller's contribution to the philosophical debate about “political obligation.” Participants in the debate have neglected his (...) work. Yet perhaps it contains an argument that deserves attention. I identify four possibilities. I show that, if Fuller were to defend his assumption that his theory of law is able to account for the alleged obligation to obey the law, he would not take the first option. He would, I suggest, choose the second or the third. I claim, however, that neither is persuasive. Moreover, they fail in such a way that the fourth possibility need not even be considered. Fuller’s assumption, I conclude, is unwarranted. (shrink)

What factors affect judicial decision-making? The legal system is of utmost importance because of its impact on our lives. Judges appear to have the most power among any social workers seeing as the precedents set in their decisions are tantamount to written law. Nevertheless, judges may be subject to certain biases, moral and cognitive alike, which influence their rulings. Looking into how morality and cognitive biases affect judges may also reveal how we as individuals handle combining morals with ethics- as (...) well as whether any discrepancies among ourselves are justifiable. An investigation into relevant moral and jurisprudential theories revealed much about the inner workings of a judge’s mindset- whether he or she recognizes it or not. Coupling this with corroborated research on a select few heuristics present specifically for judges sets the foundation for an array of possible solutions in order to ensure the most impartial judicial proceedings. Plausible remedies include conducting premortems, implicit association tests, and a revised ruling procedure. (shrink)

Referring to Reichlin’s reflections, the author analyzes the aporias arised in the debate on euthanasia, proposes to establish some general principles (e.g. inviolability of human life, the prohibition of extend unnecessary suffering, the principle of autonomy) and a method of application of them to controversial cases. The combinatorial ethics that emerges can probably solve the aporias and can harmonize the common sense (about the possibility of euthanasia in extreme cases) with Catholic doctrine – specifically referring to the Natural Moral Law (...) theory – in an attempt to integrate the results of combinatorial ethics with the principles established in this doctrine. The conclusions, although admittedly provisional, are translated into indications for an hypothetical legislator, in order to overcome the legislative aporia. In the final part, analyzing the religious aporia, the author proposes to include some forms of euthanasia in a total rethinking of the meaning of death, starting with the teachings of Christian faith. -/- Basandosi sulle riflessioni di Massimo Reichlin e James Rachels, l’Autore intende analizzare le principali aporie che emergono nella riflessione etica sull’eutanasia – quella filosofico-metodologica, deontologica, legislativa e religiosa. Attraverso quest’analisi, l’Autore propone di riprendere alcuni principi generali (tra cui l’indisponibilità della vita, il divieto di prolungare sofferenze inutili e il principio di autonomia), fornendo poi un metodo d’applicazione ai casi concreti. L’etica combinatoria che emerge da questa impostazione, riesce in buona misura a risolvere le aporie analizzate, armonizzando alcune intuizioni comuni (circa la liceità dell’eutanasia in casi particolarissimi ed estremi) con la dottrina cattolica corrente in materia. Nel confronto con la morale cattolica, in particolare, viene analizzata e discussa la teoria della legge morale naturale, nel tentativo di integrare i risultati dell’etica combinatoria con i principi affermati in questa dottrina. Le conclusioni teoretiche, anche se dichiaratamente provvisorie, si traducono poi in indicazioni praticate per un ipotetico legislatore, nel tentativo di superare l’ultima grande aporia, quella legislativa. Nella parte conclusiva, analizzando l’aporia religiosa, l’Autore propone di iscrivere la liceità di alcune forme di eutanasia all’interno di un complessivo ripensamento del significato della morte, partendo dal dato di fede cristiano, nel tentativo di superare la “logica della rimozione” che sembra caratterizzare la nostra contemporaneità.

In “Enduring Originalism,” Jeffrey Pojanowski and Kevin C. Walsh outline how originalism in constitutional interpretation can be grounded in modern natural law theory as developed by John Finnis. Their argument to that effect is powerful and constitutes a welcome addition both to natural law theory and to originalist theory. However, the authors chose to present their account as a superior alternative to, or modification of, “positive” (“original-law”) originalism of Stephen Sachs and William Baude. It is that aspect of the paper (...) that I focus on in this short essay. Contrary to their strong claims in that direction, Professors Pojanowski and Walsh are far from establishing that positive originalism is deficient and that that their version of natural-law-based originalism offers a plausible alternative to positivist originalism. There is also a worry that, despite professing sympathy towards the “positive turn” in originalism, “Enduring Originalism” is at its core an account of what Professors Pojanowski and Walsh think the law should be, and not what the law is; precisely the kind of argument the positive turn militates against.

The thesis examines the theoretical relationship between law and ethics. Its methodology is informed by both the existentialist tradition of ethical phenomenology and the natural law tradition in legal theory. The main claim of the thesis is that a phenomenological analysis of ethical experience, as suggested by the writings of existentialist authors such as Jean-Paul Sartre and Emmanuel Levinas, provides important support for the natural law tradition. This claim is developed and defended through detailed engagement with the natural law theory (...) of John Finnis. Specifically, I contend that Finnis’ account of moral reasoning as applying the principles of practical reasonableness to a context of self-evident, basic values gains significant support from a phenomenological theory of ethical experience. Finnis’ emphasis on the irreducible role of choice in moral deliberation also finds support in the existentialist tradition. However, I criticise some key aspects of Finnis’ theory, including his emphasis on the transcendental character of the basic values and his account of legal obligation. I begin by outlining some central features of the existentialist approach to philosophy. I advance an interpretation of existentialism as ethical phenomenology. I then discuss some possible methodological connections between the existentialist and natural law traditions. This discussion provides the methodological framework for the remainder of the thesis. The thesis develops and defends a substantially original theory of the relationships between law, ethics and politics. The exposition begins with an account of the relationship between law and community that draws upon the work of Finnis and G. W. F. Hegel. I then outline a phenomenological theory of ethical experience, drawing in particular on the writings of Sartre and Levinas. I employ this phenomenological account of ethics to develop a conception of moral reasoning as reflective, good faith engagement with pre-reflective social judgements of ethical significance. This view of ethical experience and moral reasoning is then used as the basis for an examination of the concept of law and its relationship to political discourse. I turn next to the notions of legal authority and obligation. I argue that law, in the focal sense of the term, presents a generic, peremptory obligation that is necessarily moral in character. In the course of the argument, I critically discuss the conceptions of legal authority proposed by Joseph Raz, Adolf Reinach, H. L. A. Hart, John Rawls, Finnis, Jacques Derrida and Hans Kelsen. This view of legal obligation entails there are fundamental moral conditions that positive rules must satisfy to qualify as law, in the focal sense. I explore the nature of the moral framework created by these conditions through a detailed analysis of the ethical foundations of political discourse. I argue that political discourse is founded upon an ontological apprehension of the nature of humans as free, ethical beings, which finds expression in a developed notion of political freedom. I suggest that the distinction between positive and negative forms of freedom advanced by Isaiah Berlin is best understood in terms of the different types of political claims invoked by those conceptions. I develop this theory by reference to the work of Charles Taylor, Gerald C. MacCallum, Wesley Newcomb Hohfeld, W. D. Ross, Robert Nozick and F. A. Hayek. I conclude by discussing the role of ethical experience in the interpretation of legal materials. I argue that ethical judgements play an irreducible role in constructing the natural interpretive context for judicial reasoning. I engage with the work of Hart, Lon L. Fuller, Martin Heidegger, Hans-Georg Gadamer, Ferdinand de Saussure and Ronald Dworkin, among others. In the final substantive chapter of the thesis, the potential for ethical judgements to play a constructive role in judicial action is illustrated through a detailed discussion of the doctrine of government neutrality.

Anglo-American general jurisprudence remains preoccupied with the relationship of legality to morality. This has especially been so in the re-reading of Lon Fuller’s theory of an implied morality in any law. More often than not, Fuller has been said to distinguish between the identity of a discrete rule and something called ‘morality’. In this reading of Fuller, however, insufficient attention to what is signified by ‘morality’. Such an implied morality has been understood in terms of deontological duties, the Good life, (...) naturalism, and subjectively posited values. Each of these interpretations has a shared common denominator: namely, the distinction between ‘is’ and ‘ought’, ‘facts’ and ‘values’. Legality is said to be nested in an ‘is’ world. An ‘is’ cannot be derived from an ‘ought’. This essay aims to press this distinction further. Fuller, I intend to argue, does indeed accept the is/ought distinction as have his commentators. The associations of the ‘oughts’ with deontological duties, the Good life, naturalism and subjective values, however, have been misdirected. This has been so because Fuller presupposed that legality was a matter of a spatial structure. Non-law was situated outside the structure. If a legislator or judge considered matters outside the structure as if they were binding upon jurists and, for that matter, upon members of the legal structure, the law was not binding. The crucial incident of the structure was the boundary of the structure. Fuller’s structuralist theory of law offers the opportunity to better understand what he signified by ‘the internal morality of law’. I shall privilege several elements of his theory: the relation of legal units to a structure, the nature of a structure, the constituents of a structure (territorial space, its pillars and its matter); the forms of the legal structure; the centrifugal and centripetal structures, the structure and traditional theories of morality, the role of the legal official in a structure, and why the internal knowledge in the structure is binding. Fuller especially privileged two features of a legal structure. The one was the boundary of the structure. The second concerned the exteriority of the boundary. Both features presupposed a territorial sense view of legal knowledge. The legal mind analysed any social problem through the map of such a sense of legal space. By concentrating upon the discrete rule in isolation of the implied structural boundary to which the rule referred, commentators have attributed been misdirected in their analyses of Fuller’s theory of law and morality. My argument in this respect will proceed as follows. In order to clarify Fuller’s senses of the morality of law, I shall first outline what he means by a ‘structure’. Second, how is the structure related to legal knowledge? Third, what are the various forms of the structure? Fourth, is the structure centrifugal or centripetal? And finally, why is the structure binding? (shrink)

The thrust of this paper addresses how the notion of an author relates to the authority of a law. Drawing from the legal thought of Hobbes, Bentham, and John Austin, the Paper offers a sense of the author as a distinct institutional source of the state. The Paper then addresses the more difficult legal theories in this context: those of HLA Hart, Ronald Dworkin and Hans Kelsen. The clue to the latter as well as the earlier theorists is a presupposed (...) inaccessible author or ghost. The presupposed ghost of the law is crucial to the binding character of a law. (shrink)

In the debate between positivism and non-positivism the argument from relativism plays a pivotal role. The argument from relativism, as put forward, for instance, by Hans Kelsen, says, first, that a necessary connection between law and morality presupposes the existence of absolute, objective, or necessary moral elements, and, second, that no such absolute, objective, or necessary moral elements exist. My reply to this is that absolute, objective, or necessary moral elements do exist, for human rights exist, and human rights exist (...) because they are justifiable. (shrink)

The argument of this article is that the dual-nature thesis is not only capable of solving the problem of legal positivism, but also addresses all fundamental questions of law. Examples are the relation between deliberative democracy and democracy qua decision-making procedure along the lines of the majority principle, the connection between human rights as moral rights and constitutional rights as positive rights, the relation between constitutional review qua ideal representation of the people and parliamentary legislation, the commitment of legal argumentation (...) to both authoritative and non-authoritative reasons, and the distinction between rules as expressing a real “ought” and principles as expressing its ideal counterpart. All of this underscores the point that the dual nature of law is the single most essential feature of law. (shrink)

And the (...) theory is applied to the case of the Five Emperors of ancient China: How to evolve from polygamy to monogamy Dov. Finally, the sexual liberation of the country and the Catholic countries of ethics as a policy to do more. This paper will attempt to explore the relationship between culture, history and the natural law. The natural moral law, based on a universally shared nature, provides a common starting point for moral dialogue between different religious, cultural and philosophical systems. Further, for Maritain history and human experience can provide a test by which competing ethical theories can be tested. (shrink)

This book analyses the general structure of constitutional rights reasoning under the German Basic Law. It deals with a wide range of problems common to all systems of constitutional rights review.

This essay introduces the philosophy of legal information (PLI), which is a response to the radical changes brought about in philosophy by the information revolution. It reviews in some detail the work of Luciano Floridi, who is an influential advocate for an information turn in philosophy that he calls the philosophy of information (PI). Floridi proposes that philosophers investigate the conceptual nature of information as it currently exists across multiple disciplines. He shows how a focus on the informational nature of (...) traditional philosophical questions can be transformative for philosophy and for human self-understanding. The philosophy of legal information (PLI) proposed here views laws as a body of information that is stored, manipulated, and analyzed through multiple methods, including the computational methodologies. PLI offers resources for evaluating the ethical and political implications of legal infomatics (also known as "legal information systems"). -/- This essay introduces PLI. Parts I and II describe Floridi's philosophy of information. First, Part I introduces the transformation in the concept of information that occurred in the twentieth century through the work of Alan Turning and Claude Shannon. Part II describes Floridi's approaches to traditional questions in epistemology, ontology, and ethics. Part III applies PI to the analysis of legal positivism. It suggests that PLI is a viable project that has potential for transforming the understanding law in the information age. -/- . (shrink)

In this essay I argue that the ethical and political position known as libertarianism is logically incoherent and, as such, cannot serve as a sound basis for either political theory or public policy. Given that the libertarian position is frequently used to provide the rationale for many of the economic (if not the social) policies of the right, a recognition of this incoherence is especially relevant to us today.

Following extended periods of conflict or repression, political reconciliation is indispensable to the establishment or restoration of democratic relationships and critical to the pursuit of peacemaking globally. In this book, Colleen Murphy offers an innovative analysis of the moral problems plaguing political relationships under the strain of civil conflict and repression. Focusing on the unique moral damage that attends the deterioration of political relationships, Murphy identifies the precise kinds of repair and transformation that processes of political reconciliation ought to promote. (...) Building on this analysis, she proposes a normative model of political relationships. A Moral Theory of Political Reconciliation delivers an original account of the failure and restoration of political relationships, which will be of interest to philosophers, social scientists, legal scholars, policy analysts, and all those who are interested in transitional justice, global politics, and democracy.

Ronald Dworkin's theory of law forges a close connection between questions about the truth of propositions of law and the question of political obligation: law as integrity is a theory of legal practice that purports to explain, not only how the content of law is determined, but also why the law—in ordinary cases—imposes an obligation of obedience. The theory (as presented) is ultimately incoherent. If we accept Dworkin's theory of the grounds of law we are obliged to reject his claims (...) about its force; alternatively, if we accept his view of the force of law, we must reject his theory about its grounds: he cannot be correct about both force and grounds. Dworkin supposes that, in extraordinary cases, the force of law is cancelled or overridden; but the relevant considerations of justice are wholly internal to our identification of the content of law. Consistently elaborated, integrity denies the offending requirements legal status: lex injusta non est lex. (shrink)

In his influential work, The Concept of Law, H. L. A. Hart levels several criticisms at the traditional natural law principle: lex iniusta non est lex. Although some of his criticisms have received a great deal of careful evaluation, others have not. In this paper I will focus on several ways in which Hart attempts to undermine the value of this principle. I will pay particularly close attention to his claims concerning the unfortunate effects that follow from either scholars’ or (...) ordinary citizens’ acceptance of this principle. It is my aim to show that his criticisms of this principle fail. It must be noted that my end is a modest one. I do not attempt to clear all possible objections to this principle, nor conclusively prove its value, but merely show that one set of arguments against it fails. Although this aim is surely modest, it is, I contend, nonetheless important. Investigating the relationship between morality and legality is undoubtedly one of the central tasks of legal philosophy. Since the time of Plato, natural law theories, although differing on various particulars, have proposed a powerful answer concerning this relationship. It is clear that these theories no longer receive the attention they once did, at least in part because of Hart’s objections. I intend to show that these objections fail to show the inadequacy of the lex iniusta principle. (shrink)

The following responses to the scholars who were kind enough to comment on my Natural Justice in this symposium have been kept to a minimum by addressing only issues where I think a misunderstanding may have arisen.

Legal theorists are familiar with John Finnis's book Natural Law and Natural Rights, but usually overlook his interventions in US constitutional debates and his membership of a group of conservative Catholic thinkers, the 'new natural lawyers', led by theologian Germain Grisez. In fact, Finnis has repeatedly advocated conservative positions concerning lesbian and gay rights, contraception and abortion, and his substantive moral theory derives from Grisez. Bamforth and Richards provide a detailed explanation of the work of the new natural lawyers within (...) and outside the Catholic Church - the first truly comprehensive explanation available to legal theorists - and criticize Grisez's and Finnis's arguments concerning sexuality and gender. New natural law is, they argue, a theology rather than a secular theory, and one which is unappealing in a modern constitutional democracy. This book will be of interest to legal and political theorists, ethicists, theologians and scholars of religious history. (shrink)

This major contribution to the history of philosophy provides the most comprehensive guide to modern natural law theory available, sets out the full background to liberal ideas of rights and contractarianism, and offers an extensive study of the Scottish Enlightenment. The time span covered is considerable: from the natural law theories of Grotius and Suarez in the early seventeenth century to the American Revolution and the beginnings of utilitarianism. After a detailed survey of modern natural law theory, the book focuses (...) on the Scottish Enlightenment and its European and American connections. Knud Haakonssen explains the relationship between natural law and civic humanist republicanism, and he shows the relevance of these ideas for the understanding of David Hume and Adam Smith. The result is a completely revised background to modern ideas of liberalism and communitarianism. (shrink)

This paper argues against the indeterminacy thesis that attempts to defeat traditional natural law by asserting that specific moral norms cannot be based on human nature. As put by Jean Porter (Nature as Reason 2005, 338): “the intelligibilities of human nature underdetermine their forms of expression, and that is why this theory does not yield a comprehensive set of determinate moral norms, compelling to all rational persons.” However, if this were so, one could adopt any morality with impunity from nature’s (...) sanctions. But I argue that nature punishes violators of the natural law in various ways. In addition, I argue that the indeterminacy thesis cannot be supported by appealing to the diversity of moral norms across the globe. Such diversity is required, for instance, both by the reliance of Thomistic natural law on the practical syllogism and by its reliance on practical reason’s ability to prescribe for the sake of the person in highly unique situations as required by Wojtyla’s Personalistic Norm and Aquinas’s norm of neighborly love.
