David Gauthier stages a competition between two arguments, each of which purports to decide once for all transparent agents which is best, being a straight or being a constrained maximizer. The first argument, which he criticizes and rejects, is for the greater utility, on a certain weak assumption, of straight maximization for all transparent agents. The second, which he endorses, is for the greater utility on the same weak assumption of constrained maximization for all transparent agents.In Section I, Gauthier’s account (...) of constrained maximization is presented, and his use in the two arguments of the idea of choosing a disposition to choose actions is noted. Section II is about the unfortunate argument that Gauthier criticizes. This argument is flawed in ways additional to those he notices, but a less ambitious form of reasoning can, for individuals whose probabilities and values are right, be good for the greater expected utility of straight maximization. Section III takes up the argument that Gauthier endorses and maintains that it is wrong in a way specific to it as well as in ways closely related to all of the first argument’s noted flaws. An Appendix features a three-person prisoners’ dilemma and includes demonstrations of principal conclusions reached in the body of this paper. (shrink)

When is a moral theory self-defeating? I suggest the following. There are certain things we ought to try to achieve. Call these our moral aims. Our moral theory would be self-defeating if we believed we ought to do what will cause our moral aims to be worse achieved. Is this ever true? If so, what does it show?

This book examines some of the deepest questions in philosophy: What is involved in judging a belief, action, or feeling to be rational?

In his recent paper, “Justice as Fairness: Political not Metaphysical,” John Rawls makes use of a footnote to disown what to many readers must have seemed one of the most striking and original underlying ideas of his theory of justice, that it “is a part, perhaps the most significant part, of the theory of rational choice.” That Rawls should issue this disclaimer indicates, at least in my view, that he has a much clearer understanding of his theory, and its relationship (...) to rational choice than he did at the time that he wrote A Theory of Justice. As I note in Morals by Agreement, Rawls does not show that principles of justice are principles of rational choice. Hence, in appropriating the idea, I can claim diat I am undertaking a pioneering enterprise. No doubt Thomas Hobbes would have undertaken it had the resources of the theory of rational choice been at his disposal, but I do not intend to pursue counterfactuals in a search for historical antecedents. Moral theory as rational choice theory is, I claim, a new venture. (shrink)

Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

John Charvet presents an original philosophical theory that transcends the liberal-communitarian debate and justifies universally valid principles of prudential and moral reason. The Idea of an Ethical Community rejects contemporary positions - the liberal theorist's politically neutral stance toward alternative conceptions of good, on the one hand, and the communitarian's moral relativism, on the other. Charvet espouses what he calls an "antirealist" view of shared norms and maintains that although reason cannot be unconditionally authoritative, there can be conditionally definitive rational (...) principles. His book advances a view of the ethical community consistent both with the contractarian idea of John Rawls's early work. A Theory of Justice and with a due emphasis on communitarian values. But he grounds this view of the ethical community in a theory of the autonomous person and a theory of value. (shrink)

Ethical concepts are, or purport to be, normative. They make claims on us: they command, oblige, recommend, or guide. Or at least when we invoke them, we make claims on one another; but where does their authority over us - or ours over one another - come from? Christine Korsgaard identifies four accounts of the source of normativity that have been advocated by modern moral philosophers: voluntarism, realism, reflective endorsement, and the appeal to autonomy. She traces their history, showing how (...) each developed in response to the prior one and comparing their early versions with those on the contemporary philosophical scene. Kant's theory that normativity springs from our own autonomy emerges as a synthesis of the other three, and Korsgaard concludes with her own version of the Kantian account. Her discussion is followed by commentary from G. A. Cohen, Raymond Geuss, Thomas Nagel, and Bernard Williams, and a reply by Korsgaard. (shrink)

This book offers the fullest and most sophisticated account of Gert's influential moral theory, a model first articulated in the classic work The Moral Rules: A New Rational Foundation for Morality, published in 1970. In this final revision, Gert makes clear that the moral rules are only one part of an informal system that does not provide unique answers to every moral question but does always provide a range of morally acceptable options. A new chapter on reasons includes an account (...) of what makes one reason better than another and a second new chapter is devoted to the question of justifying violations of the rules. Moral impartiality, the moral ideals, and virtue and vice, are all treated in greater detail. Throughout, Gert attempts to answer all of the challenges that his work has provoked. (shrink)

Controversies about optimality models and adaptationist methodologies have animated the discussions of evolutionary theory in recent years. The sociobiologists, following the lead of E. O. Wilson, have argued that if Darwinian natural selection can be reliably expected to produce the best possible type of organism - one that optimizes the value of its genetic contribution to future generations - then evolution becomes a powerfully predictive theory as well as an explanatory one. The enthusiastic claims of the sociobiologists for the predictability (...) and applicability that the optimalist approach engenders have been met with severe criticism by Richard C. Lewontin, Stephen Jay Gould, and other biologists and philosophers of biology. These original essays take up both sides of the controversy over the role of optimality models in evolutionary biology, providing a refreshingly insightful and balanced discussion of optimality issues by an interdisciplinary group of leading philosophers of biology, biologists, psychologists, anthropologists, and an economist. They focus on the current state of adaptationist and optimalist methodology in evolutionary theory, and on the possibility of extending such methodology to the human sciences, especially those of psychology and anthropology.

What are ethical judgments about? And what is their relation to practice? How can ethical judgment aspire to objectivity? The past two decades have witnessed a resurgence of interest in metaethics, placing questions such as these about the nature and status of ethical judgment at the very center of contemporary moral philosophy. Moral Discourse and Practice: Some Philosophical Approaches is a unique anthology which collects important recent work, much of which is not easily available elsewhere, on core metaethical issues. Reinvigorated (...) naturalist moral realism and the various versions of moral realism, as well as irrealist, expressivist, and neo-Kantian constructivist theories are all represented in this fine collection, constituting a rich array of approaches to contemporary moral philosophy's most fundamental debates. An extensive introduction by Darwall, Gibbard, and Railton is also included, making this volume the most comprehensive and up-to-date work of its kind. Moral Discourse is ideally suited for use in courses in contemporary ethics, ethical theory, and metaethics. (shrink)
