My aim is to defend the conscience principle: One ought never to act against the dictates of one’s conscience. In the first part of this paper, I explain what I mean by “conscience” and “dictate of conscience,” and I show that the notion that the conscience principle is inherently anti-authoritarian or inherently fanatical is mistaken. In the second part, I argue that the existence of mistaken conscience does not reduce the conscience principle to absurdity. In the third part, I present two arguments for the plausibility of that principle.

The Philosophy of Law is a broad-reaching text that guides readers through the basic analytical and normative issues in the field, highlighting key historical and contemporary thinkers and offering a unified treatment of the various issues in the philosophy of law. Enlivened with numerous, everyday examples to illustrate various concepts of law. Employs the idea of three central commonplaces about law - that law is a social matter, that law is authoritative, and that law is for the common good - to organize seemingly disparate topics and to bring rival views into contention with each other. The first volume in the Fundamentals of Philosophy series, in which leading philosophers explore the fundamental issues and core problems in the major sub-disciplines of philosophy

Natural law theory has been undergoing a revival, especially in political philosophy and jurisprudence. Yet, most fundamentally, natural law theory is not a political theory, but a moral theory, or more accurately a theory of practical rationality. According to the natural law account of practical rationality, the basic reasons for actions are basic goods that are grounded in the nature of human beings. Practical rationality aims to identify and characterize reasons for action and to explain how choice between actions worth performing can be appropriately governed by rational standards. These standards are justified by reference to features of the human goods that are the fundamental reasons for action. This book is a defence of a contemporary natural law theory of practical rationality, demonstrating its inherent plausibility and engaging systematically with rival egoist, consequentialist, Kantian and virtue accounts.

It seems to be a widely shared view that any defensible desire-fulfillment theory of welfare must be framed not in terms of what an agent, in fact, desires but rather in terms of what an agent would desire under hypothetical conditions that include improved information. Unfortunately, though, such accounts are subject to serious criticisms. In this paper I show that in the face of these criticisms the best response is to jettison any appeal to idealized information conditions: the considerations put forward in support of the appeal to what would be desired in hypothetical circumstances of improved information do not, in fact, give adequate reason to make that appeal.

In lieu of an abstract, here is a brief excerpt of the content:Desire and Ethics in Hobbes's Leviathan:A Response to Professor DeighAccording to the "orthodox" interpretation of Hobbes's ethics, the laws of nature are the products of means-end thinking. According to the "definitivist" interpretation recently offered by John Deigh, the laws of nature are generated by reason operating on a definition of "law of nature," where the content of this definition is given by linguistic usage.2 I aim to accomplish two things in this note. First, I want to locate as clearly as possible the point at which the orthodox and definitivist interpretations must disagree. Second, I want to show that once the claim on which these interpretations disagree is made clear, it is the orthodox interpretation that turns out to be the superior.31.Deigh takes as the initial test case for the various interpretations of Hobbes's moral theory the passage in chapter fifteen of Leviathan commonly known as "the reply to the fool." The fool, it will be recalled, argues that the precept that covenants be kept is not a rule of reason; Hobbes argues that the fool's "specious reasoning is neverthelesse [End Page 259] false," for to break a valid covenant is to violate a dictate of reason.4 Deigh summarizes his criticism of the orthodox interpretation of this passage as follows.On [the orthodox] interpretation, the dispute between Hobbes and the Fool concerns the deliverances of reason when reason is exercised in the service of self-interest, that is, when its exercise consists in determining the fittest means to achieving the ends set by egoistic desires. Such an exercise falls outside of the definition of reason that Hobbes gives in chapter five. It exemplifies strategic or means-to-end thinking and not deduction. Indeed, it corresponds to what Hobbes, in chapter three, defines as seeking... Hence, the orthodox interpretation of the laws of nature implies that Hobbes, in expounding the laws of nature, went back on the notion of reason he defined in chapter five. It implicitly attributes a fundamental inconsistency to Hobbes's philosophy.5The laws of nature—among which is the rule requiring the keeping of covenants6 —are held by Hobbes to be precepts of reason.7 Hobbes deems them, collectively, a science,8 by which he means that they are the deliverances of reason that pertain to a specific subject-matter.9 But, argues Deigh, Hobbes understands reason in a very specific way, a way that is distinct from the sort of means-end thinking that Hobbes describes in detail in chapter three and labels "seeking." Thus the orthodox interpretation of Hobbes's moral theory is at odds with Hobbes's own conception of the laws of nature individually as dictates of reason and collectively as the science of the true moral philosophy.It is of course true that the sort of thinking that Hobbes calls "seeking" and the sort of thinking that Hobbes calls "reasoning" are fundamentally different. Seeking takes its origin from experience: we have seen certain events following other events, and we retain a trace of that experience in imagination. Thus when we have some desire, there arises "the Thought of some means we have seen produce the like of that which we ayme at; and from the thought of that, the thought of means to that mean; and so continually, till we come to some beginning within our power."10 Those that are able to engage in this sort of thinking well are prudent,11 and on Hobbes's view, humans with comparable experience will exhibit a comparable degree of prudence.12 And because seeking requires only desire to regulate thought and some experience of events succeeding other events, there is nothing distinctively human about this form of thinking, and indeed Hobbes acknowledges that prudence is common to humans and other animals.13 By contrast, the process that Hobbes calls "reasoning" [End Page 260] is characterized independently of desire. All that is essential to reasoning is that it involves the drawing of consequences that follow from sentences formed from aptly-defined general terms.14 Thus all deliverances of reason are, either explicitly or implicitly, conditional in form: necessarily, if p...

What is Justice? Classic and Contemporary Readings, 2/e, brings together many of the most prominent and influential writings on the topic of justice, providing an exceptionally comprehensive introduction to the subject. It places special emphasis on "social contract" theories of justice, both ancient and modern, culminating in the monumental work of John Rawls and various responses to his work. It also deals with questions of retributive justice and punishment, topics that are often excluded from other volumes on justice. This new edition features expanded and updated readings on justice and punishment and includes more recent responses to John Rawls's work. Part One of the book features selections from classical sources including Homer, Plato, Aristotle, Aquinas, and Mencius, as well as excerpts from the Bible and the Koran. Part Two provides readings on the state of nature and the social contract, from Hobbes and Locke to Rawls, Nozick, Gauthier, and Baier. Part Three includes the Declaration of Independence and Amendments to the U.S. Constitution in addition to selections on property and social justice by Locke, Hume, Adam Smith, Engels, Marx, Mill, and several contemporary authors. Part Four offers a wide variety of readings on punishment, several of which address the death penalty. Part Five begins with selections from Rawls's work and includes responses from Dworkin, Nagel, Nozick, MacIntyre, Sandel, Walzer, Okin, and Rawls himself. Each selection is preceded by a brief introduction and each of the five parts opens with an introduction. The volume is further enhanced by a general introduction and an updated and extensive bibliography. Ideal for a wide variety of courses including social and political philosophy, ethics, philosophy of law, and contemporary moral problems, What Is Justice?, 2/e, does not assume any philosophical or specialized background. It is also engaging reading for anyone interested in justice.

The aim of this paper is to take the first steps toward providing a refurbished consent theory of political authority, one that rests in part on a reconception of the relationship between the surrender of judgment and the authoritativeness of political institutions. On the standard view, whatever grounds political authority implies that one ought to surrender one's judgment to that of one's political institutions. On the refurbished view, it is the surrender of one's judgment – which can plausibly be considered a form of consent – that makes political institutions practically authoritative.

The moral formulation of philosophical anarchism is that most persons, even in just political communities, do not have a moral obligation to obey the law. The epistemological formulation of philosophical anarchism is that most persons are unjustified in believing that they have a moral obligation to obey the law. But the philosophical anarchists’ argument strategies do not, and in fact cannot, show that belief in the moral obligation to obey the law is unjustified. And, further, given that most persons in just political communities do believe that they are under such an obligation, the moral requirement that one ought to act in accordance with one’s conscience implies that most persons have a moral obligation to obey the law. Thus the moral formulation of philosophical anarchism is false and the epistemological formulation unjustified

There is a story about the connection between the rise of consent theories of political obligation and the fall of natural law theories of political obligation that is popular among political philosophers but nevertheless false. The story is, to put it crudely, that the rise of consent theory in the modern period coincided with, and came as a result of, the fall of the natural law theory that dominated during the medieval period. Neat though it is, the story errs doubly, for it supposes both that consent did not play a key role in natural law theories of political authority offered in the medieval period (a supposition falsified by close inspection of the view of Aquinas, perhaps the paradigmatic natural law theorist) and that natural law theory did not play a key role in the consent theories of political authority offered in the modern period (a supposition falsified by close inspection of the views of Hobbes and Locke, perhaps the paradigmatic consent theorists).Footnotes* I owe thanks to Pat Káin, Paul Weithman, Bob Roberts, and Henry Richardson for instructive criticisms. John Hare was particularly helpful both in criticism and in conversation. I was supported by a fellowship from the Erasmus Institute while this essay was drafted
