The attempt to justify morality comes from our concern about how we should live. It intends to tell us what we should do by showing that there are reasons for doing it. This dissertation examines how we can succeed in justifying morality rationally after investigating what it is to provide a rational basis for 'being moral' and why we seek to do it. We find in the theory of rational choice a framework which is very useful for the justification of morality. However, an examination of projects based on rational choice theory reveals that even if one adopts that framework, he is doomed to failure if he interprets reason only instrumentally. Non-instrumental rationality is primarily concerned with the rationality of ends, which can be construed in terms of Kant's conception of practical reason. With help of the rational choice framework understood non-instrumentally we can make clear how reason motivates us to moral actions and why we should follow reason.

Is it rational to be moral? How do rationality and morality fit together with being human? These questions are at the heart of David Schmidtz's exploration of the connections between rationality and morality. This inquiry leads into both metaethics and rational choice theory, as Schmidtz develops conceptions of what it is to be moral and what it is to be rational. He defends a fairly expansive conception of rational choice, considering how ends as well as means can be rationally chosen and explaining the role of self-imposed constraints in a rational life plan. His moral theory is dualistic, ranging over social structure as well as personal conduct and building both individual and collective rationality into its rules of recognition for morals. To the "why be moral" question, Schmidtz responds that being moral is rational, but he does not assume we have reasons to be rational. Instead, Schmidtz argues that being moral is rational in a particular way and that beings like us in situations like ours have reasons to be rational in just that way. This approach allows him to identify decisive reasons to be moral; at the same time, it explains why immorality is as prevalent as it is. This book thus offers a set of interesting and realistic conclusions about how morality fits into the lives of humanly rational agents operating in an institutional context like our own.

The Handbook of Business Ethics: Philosophical Foundations is a standard interdisciplinary reference handbook in the field of business ethics. Articles by notable philosophers and economists examine fundamental concepts, theories and questions of business ethics: Are morality and self-interest compatible? What is meant by a just price? What did the Scholastic philosophers think about business? The handbook will cover the entire philosophical basis of business ethics. Articles range from historical positions such as Aristotelianism, Kantianism and Marxism to systematic issues like justice, religious issues, rights and globalisation or gender. The book is intended as a reference work for academics, students (esp. graduate), and professionals.

Philosophy, economics, and decision theory have long been dominated by the idea that rational choice consists of seeking or achieving one's own greatest good. Beyond Optimizing argues that our ordinary understanding of practical reason is more complex than this, and also that optimizing/maximizing views are inadequately supported by the considerations typically offered in their favor. Michael Slote challenges the long-dominant conception of individual rationality, which has to a large extent shaped the very way we think about the essential problems and nature of rationality, morality, and the relations between them. He contests the accepted view by appealing to a set of real-life examples, claiming that our intuitive reaction to these examples illustrates a significant and prevalent, if not always dominant, way of thinking. Slote argues that common sense recognizes that one can reach a point where "enough is enough," be satisfied with what one has, and, hence, rationally decline an optimizing alternative. He suggests that, in the light of common sense, optimizing behavior is often irrational. Thus, Slote is not merely describing an alternative mode of rationality; he is offering a rival theory. And the numerous parallels he points out between this common-sense theory of rationality and common-sense morality are then shown to have important implications for the long-standing disagreement between commonsense morality and utilitarian consequentialism. Beyond Optimizing is notable for its use of a much richer vocabulary of criticism than optimizing/maximizing models ever call upon. And it further argues that recent empirical investigations of the development of altruism and moral motivation need to be followed up by psychological studies of how moderation, and individual rationality more generally, take shape within developing individuals.

Breakthroughs in biomedicine often lead to new life-giving treatments but may also raise troubling, even life-and-death, quandaries. Society's Choices discusses ways for people to handle today's bioethics issues in the context of America's unique history and cultureâ€"and from the perspectives of various interest groups. The book explores how Americans have grappled with specific aspects of bioethics through commission deliberations, programs by organizations, and other mechanisms and identifies criteria for evaluating the outcomes of these efforts. The committee offers recommendations on the role of government and professional societies, the function of commissions and institutional review boards, and bioethics in health professional education and research. The volume includes a series of 12 superb background papers on public moral discourse, mechanisms for handling social and ethical dilemmas, and other specific areas of controversy by well-known experts Ronald Bayer, Martin Benjamin, Dan W. Brock, Baruch A. Brody, H. Alta Charo, Lawrence Gostin, Bradford H. Gray, Kathi E. Hanna, Elizabeth Heitman, Thomas Nagel, Steven Shapin, and Charles M. Swezey.

The marriage of neuroscience and the science of choice behaviour gave birth to neuroeconomics. Jan de Jong explores this new discipline, investigating the relationship between choice behaviour and brain activity, and the light that this sheds on our systems of reasoning.

The assumption that rewards and punishments influence our choices between different courses of action underlies economic, sociological, psychological, and legal thinking about human action. Hence, the notion of a reasoning criminal--one who employs the same sorts of cognitive strategies when contemplating offending as they and the rest of us use when making other decisions--might seem a small contribution to crime control. This conclusion would be mistaken. This volume develops an alternative approach, termed the "rational choice perspective," to explain criminal behavior. Instead of emphasizing the differences between criminals and non-criminals, it stresses some of the similarities. In particular, while the contributors do not deny the existence of irrational and pathological components in crimes, they suggest that the rational aspects of offending should be explored. An international group of researchers in criminology, psychology, and economics provide a comprehensive review of original research on the criminal offender as a reasoning decision maker. While recognizing the crucial influence of situational factors, the rational choice perspective provides a framework within which to incorporate and locate existing theories about crime. In doing so it also provides both a new agenda for research and sheds a fresh light on deterrent and prevention policies.

Michael Moehler develops a novel multilevel social contract theory. In contrast to existing theories in the liberal tradition, it does not merely assume a restricted form of reasonable moral pluralism, but is tailored to the conditions of deeply morally pluralistic societies which may be populated by liberal moral agents, nonliberal moral agents, and, according to the traditional understanding of morality, nonmoral agents alike. Moehler draws on the history of the social contract tradition, especially the work of Hobbes, Hume, Kant, Rawls, and Gauthier, as well as on the work of some of the critics of this tradition, such as Sen and Gaus. Moehler's two-level contractarian theory holds that morality in its best contractarian version for the conditions of deeply morally pluralistic societies entails Humean, Hobbesian, and Kantian moral features. The theory defines the minimal behavioral restrictions that are necessary to ensure, compared to violent conflict resolution, mutually beneficial peaceful long-term cooperation in deeply morally pluralistic societies. The theory minimizes the problem of compliance in morally diverse societies by maximally respecting the interests of all members of society. Despite its ideal nature, the theory is, in principle, applicable to the real world and, for the conditions described, most promising for securing mutually beneficial peaceful long-term cooperation in a world in which a fully just society, due to moral diversity, is unattainable. If Rawls' intention was to carry the traditional social contract argument to a higher level of abstraction, then the two-level contractarian theory brings it back down to earth.

'The Rational and the Moral Order' is a significant book providing a comprehensive theory of morality. The opening chapter is simply marvellous. Baier provides a cogent response to Hume's conundrums on practical reasoning: logical entailment, he argues, is not the correct model of the relation between reasons and that for which they are reasons. Indeed, the giving of reasons is, in part, a social enterprise, and there is no necessary connection between rationality and self-interest. Just as the giving of reasons is a social enterprise taught to succeeding generations, so too is the moral enterprise, for a moral order is a social order of some sort. It is a social order that encourages a critical stance toward, and permits the correction of, its mores. Moral precepts can be sound or unsound, and yet can be relative to a moral order. In the concluding chapter Baier shows how his theoretical framework can be used to confront some of the moral problems people face, problems which have also exercised contemporary philosophers. Though there are many philosophers who believe that killing is worse than letting anyone die, there are few that defend the view other than by raw intuition. Baier deploys the resources of his theory of morality in support of this widely shared but poorly defended viewpoints. "Along the way, Baier deals with virtually all the problems that have taxed moral philosophers for a very long time -- rationality, responsibility, morality's relation to law, the good life, prisoner's dilemma, moral motivation, and others. The Rational and the Moral Order is careful, insightful, and convincing." --Theodore M. Benditt, University of Alabama

This book explores the role of artificial intelligence in the development of a claim that morality is person-made and rational. Professor Danielson builds moral robots that do better than amoral competitors in a tournament of games like the Prisoners Dilemma and Chicken. The book thus engages in current controversies over the adequacy of the received theory of rational choice. It sides with Gauthier and McClennan, who extend the devices of rational choice to include moral constraint. Artificial Morality goes further, by promoting communication, testing and copying of principles and by stressing empirical tests.
