The standard argument for the claim that rational preferences are transitive is the pragmatic money-pump argument. However, a money-pump only exploits agents with cyclic strict preferences. In order to pump agents who violate transitivity but without a cycle of strict preferences, one needs to somehow induce such a cycle. Methods for inducing cycles of strict preferences from non-cyclic violations of transitivity have been proposed in the literature, based either on offering the agent small monetary transaction premiums or on multi-dimensional preferences. (...) This paper argues that previous proposals have been flawed and presents a new approach based on the dominance principle. (shrink)

Recently, in his Rolf Schock Prize Lecture, Derek Parfit has suggested a novel way of avoiding the Repugnant Conclusion by introducing what he calls “imprecision” in value comparisons. He suggests that in a range of important cases, populations of different sizes are only imprecisely comparable. Parfit suggests that this feature of value comparisons opens up a way of avoiding the Repugnant Conclusion without implying other counterintuitive conclusions, and thus solves one of the major challenges in ethics. In this article, I (...) try to clarify Parfit's proposal and evaluate whether it will help us with the paradoxes in population ethics. (shrink)

Here's one piece of practical reasoning: "If I do this then a person will reap some benefits and suffer some costs. On balance, the benefits outweigh the costs. So I ought to do it." Here's another: "If I do this then one person will reap some benefits and another will suffer some costs. On balance, the benefits to the one person outweigh the costs to the other. So I ought to do it." Many influential philosophers say that there is something (...) dubious about the second piece of reasoning. They say that it makes sense to trade-off costs and benefits within lives, but not across lives. In this paper I make a case for the second piece of reasoning. My case turns on the existence of morphing sequences—sequences of possible states of affairs across which people transform smoothly into other people. (shrink)

In this paper, I defend the existence of a moral duty to disobey the law and engage in civil disobedience on the basis of one of the grounds of political obligation—the Samaritan duty. Christopher H. Wellman has recently offered a ‘Samaritan account’ of state legitimacy and political obligation, according to which the state is justified in coercing each citizen in order to rescue all from the perilous circumstances of the state of nature; and each of us is bound to obey (...) the law, as the state demands, because we each have a responsibility to help rescue others when this assistance is not unreasonably costly. Though Wellman recognizes that there can be reasons for disobeying the law and resisting injustice in otherwise legitimate states, he overlooks the possibility that at least some of these reasons could be Samaritan in nature, grounded in the duty to rescue people from peril. As I shall argue, the Samaritan duty supports obligations to disobey the law, when the law prohibits Samaritan rescues, and to engage in civil disobedience, when unjust laws and practices contribute to endangering people. The discussion proceeds as follows. After a brief overview of the Samaritan duty, I articulate my case for Samaritan duties to disobey the law, and duties to engage in civil disobedience when unjust laws, institutions, or practices enable what I call ‘persistent Samaritan perils’. I then examine and respond to several objections to my account: first, that the costs of law-breaking are unreasonable, and thus cannot be morally required; second, that individuals’ particular acts of protest and civil disobedience do not appear to make any difference to the rescue, and thus cannot be required; third, that I stretch the Samaritan duty beyond recognition; and fourth, that the Samaritan duty binds us to help people in need or peril anywhere, not particularly at home. I consider in conclusion the advantages and limits of my account of citizens’ Samaritan duties in the face of injustice. (shrink)

Recently many have argued that agents must sometimes have credences that are imprecise, represented by a set of probability measures. But opponents claim that fans of imprecise credences cannot provide a decision theory that protects agents who follow it from foregoing sure money. In particular, agents with imprecise credences appear doomed to act irrationally in diachronic cases, where they are called to make decisions at earlier and later times. I respond to this claim on behalf of imprecise credence fans. Once (...) we appreciate the complexity of our intuitions about rational decision making, we can see that diachronic cases are in fact evidence for the essential claims motivating imprecise credence models. I argue that our decision theory for imprecise agents should mirror our decision theory for agents in moral dilemmas, and I develop permissive norms that explain our intuitions about both sorts of agents.

The “welcome return” to “substantive political philosophy” that Rawls'sA Theory of Justicewas said to herald has resulted in forty years of proposals seeking to show that philosophical reflection leads to the demonstrable truth of almost every and any conceivable view of the justice of property rights. Select any view—from the justice of unregulated capitalist markets to the most extreme forms of egalitarianism—and one will find that some philosophers have proclaimed that rational reflection uniquely leads to its justice. This is, I (...) believe, a sort of ideological thinking masquerading as philosophizing. In this paper, using some tools from game theory as well as experimental findings, I seek to sketch a non-ideological approach to the question of the justification of property rights. On this approach the aim of political philosophy is, first and foremost, to reflect on whether our social rules of property are within the “optimal eligible set” of rules acceptable to all. (shrink)

It seems paradoxical to say that an action's normative status ‐ whether it is right, wrong, or obligatory ‐ depends on whether or not it is performed. In this paper, I shall argue that in itself this dependency is not paradoxical. I shall argue that we should not reject a normative theory just because it implies this kind of dependency. Not all dependencies of this kind are bad, or at least not bad enough to warrant wholesale rejection. Instead, we should (...) reject a theory when this dependency makes it a poor guide to action, in particular, when the dependency makes it impossible for agents to comply with the theory. (shrink)

It is commonly asserted that “death is not a welfare issue” and this has been reflected in welfare legislation and policy in many countries. However, this creates a conflict for many who consider animal welfare to be an appropriate basis for decision-making in animal ethics but also consider that an animal’s death is ethically significant. To reconcile these viewpoints, this paper attempts to formulate an account of death as a welfare issue. Welfare issues are issues that refer to evaluations concerning (...) an animal’s interests. This includes evaluations that refer only to comparisons between the presence and absence of states, including positive states. This means that an animal’s death may be a welfare issue insofar as it leads to the exclusion of relevant positive states. This allows us to deny that death is necessarily not a welfare issue.

This article discusses the possibility of a rationally justified choice between two options neither of which is better than the other while they are not equally good either (‘3NT’). Joseph Raz regards such options as incomparable and argues that reason cannot guide the choice between them. Ruth Chang, by contrast, tries to show that many cases of putative incomparability are instead cases of parity—a fourth value relation of comparability, in addition to the three standard value relations ‘better than’, ‘worse than’ (...) and ‘equally good as’. It follows, she argues, that many choice situations in which rationally justified choice seems precluded are in fact situations within the reach of practical reason. This article has three aims: (1) it challenges Chang’s argument for the possibility of parity; (2) it demonstrates that, even if parity would exist, its problematic implications for practical reason would not differ from those of Raz’s incomparability; (3) it discusses the underlying cause of hard cases of comparison: the fact that none of the three standard value relations applies (‘3NT’). It will be shown that the problematic implications for the rational justification of the choice are due to 3NT itself, irrespective of whether 3NT is explained as incomparability or parity. (shrink)

Amos Tversky, Daniel Kahneman, Dan Ariely et quelques autres prétendent trouver de l’irrationalité quand des décideurs sont trompés par la formulation du problème qu’ils abordent. Les chercheurs notent que les sujets offrent des réponses incohérentes lorsqu’un même problème est formulé de plusieurs façons différentes. Mais quand doit-on estimer que deux problèmes sont «les mêmes»? Les sujets ne sont pas des chercheurs ni des experts en théorie de la décision. On ne peut s’attendre à ce qu’ils lisent les problèmes «comme il (...) faut». Peut-être découvrent-ils des sources d’utilité là où les chercheurs n’en soupçonnaient guère; peut-être changent-ils des valeurs qui «devraient» rester constantes. (shrink)

In this paper I argue that resource allocation in publicly funded medical systems cannot be done using a purely substantive theory of justice, but must also involve procedural justice. I argue further that procedural justice requires institutions and that these must be “local” in a specific sense which I define. The argument rests on the informational constraints on any non-market method for allocating scarce resources among competing claims of need. However, I resist the identification of this normative account of local (...) justice with the actual approach to local decision-making taken within the UK National Health Service. I illustrate my argument with reference to the case of provision of In Vitro Fertilisation within the UK NHS. (shrink)

Philosophical discussions of prioritarianism, the view that we ought to give priority to those who are worse off, have hitherto been almost exclusively focused on cases involving a fixed population. The aim of this paper is to extend the discussion of prioritarianism to encompass also variable populations. I argue that prioritarianism, in its simplest formulation, is not tenable in this area. However, I also propose several revised formulations that, so I argue, show more promise.

Workers generally face higher levels of pollution and risk in their workplace than members of the public. Economists justify the double standard on the grounds of the compensating wage differential . The CWD, or hazard-pay premium, is the increment in wages, all things being equal, that workers in hazardous environments receive, as compared to other workers. Economists defend the CWD by asserting that workers willingly trade safety for extra money. This essay examines the theory behind the CWD, presents and evaluates (...) economists' Market-Efficiency Argument for the CWD, offers several reasons for questioning the CWD, and applies the Market-Efficiency Argument to a real-world case, that of U. S. nuclear workers. The essay concludes that this argument fails to justify the CWD, at least in the case of U. S. nuclear workers. (shrink)
