The context-free weak ordering principle is viewed by many as a cornerstone of rational choice theory. McClennen, for example, claims that this principle is one of a pair on which '[t]he theory of rational choice and preference, as it has been developed in the past few decades by economists and decision theorists, rests', and Sen characterizes a version of context freedom as ‘a very basic requirement of rational choice’. But this principle is certainly not uncontroversial: there are examples of principle is certainly not apper irrational

significant role for accomplishment thereby admits a ‘Trojan Horse’ (267).1 To abandon hedonism in favour of a conception of well-being that incorporates achievement is to take the first step down a slippery slope toward the collapse of the other two pillars of utilitarian morality: welfarism and consequentialism. We shall argue that Crisp’s arguments do not support these conclusions. We begin with welfarism. Crisp defines it thus: ‘Well-being is the only value. Everything good must be good for some being or beings’ (264). The first part of this definition is potentially misleading, since it makes it sound as if welfarism adopts a monistic account of value, in which well-being is the only good thing. But well-being, as Crisp notes, when discussing hedonism, is best understood as consisting in a balance of good things over bad in one’s life. So understood, welfarism is silent on the issue of what things are good; it places a structural restriction on what kinds of things can be good: they must be things that are good for beings. It is a separate task to supply the content to fit this structure by determining what things are good, and welfarists differ in their answers: hedonists traditionally assert that pleasure alone is good; others add further items such as knowledge and virtue. Why is the thought that a person’s well-being depends importantly on what they accomplish a threat to welfarism? An accomplishment is judged both by its outcome or product and by the manner of the performance itself. But an activity or outcome is only an achievement if it is worthwhile, and whether it is worthwhile will depend on whether it exhibits what Crisp asserts to be ‘non-welfarist values’ (266), such as beauty, grace, importance, or style - excellences which welfarism, in Crisp’s view, cannot accommodate because they cannot be ‘cashed out in welfarist terms’, or ‘reduced to the value of well-being’ (266). Here Crisp rests his case, but it is worth trying to get clearer about the difficulties in order to see if the welfarist can meet them..

The two envelopes problem has generated a significant number of publications (I have benefitted from reading many of them, only some of which I cite; see the epilogue for a historical note). Part of my purpose here is to provide a review of previous results (with somewhat simpler demonstrations). In addition, I hope to clear up what I see as some misconceptions concerning the problem. Within a countably additive probability framework, the problem illustrates a breakdown of dominance with respect to infinite partitions in circumstances of infinite expected utility. Within a probability framework that is only finitely additive, there are failures of dominance with respect to infinite partitions in circumstances of bounded utility with finitely many consequences (see the epilogue)

Integration and coherence are central values in human existence. It would be a serious objection to any proposed way of life that it led to us being alienated or cut off from others or from some importan part of ourselves. Morality, with the strenuous demands it makes on us, is one area in which alienation is both particularly threatening and peculiarly undesirable. If morality cuts us off from some important part of ourselves then it appears unattractive, and if it cuts us off from others then it seems self-defeating. While there are few philosophers who take the radical view that morality is, by its very nature, an alienating force, a more common complaint has been that some particular moral theories should be rejected because the picture of moral thought which they offer inevitably leads to the alienation of moral agents. The main target of criticism has been consequentialism, but some deontological theories, especially Kantianism, have also come under attack

This paper comprises three sections. First, we offer a traditional defence of deontology, in the manner of, for example, W.D. Ross (1965). The leading idea of such a defence is that the right is independent of the good. Second, we modify the now standard account of the distinction, in terms of the agent-relative/agentneutral divide, between deontology and consequentialism. (This modification is necessary if indirect consequentialism is to count as a form of consequentialism.) Third, we challenge a value-based defence of deontology proposed by Quinn (1993), Kamm (1989, 1992), and Nagel (1995)

There is a substantial literature on the Bayesian approach, and the application of Bayes'' theorem, to legal matters. However, I have found no discussion that explores fully the issue of how a Bayesian juror might be led from an initial "presumption of innocence" to the judgment (required for conviction in criminal cases) that the suspect is "guilty beyond a reasonable doubt". I shall argue here that a Bayesian juror, if she acts in accord with what the law prescribes, will virtually never reach such a judgment. In section I, I discuss Bayesianism, Bayes'' rule and the relation between them. Section II addresses the two legal notions key to my worries about Bayesian jurors: the presumption of innocence and the reasonable doubt criterion. Section III explores what a Bayesian is to make of these notions, and how the legal system requires her to reason in their light. If I am right, there emerges a conflict between current legal prescriptions and the Bayesian approach. Section IV explores the import of this conflict and how it might be resolved.

This article examines the nature of rationality. The domain of rationality is customarily divided into the theoretical and the practical. Whereas theoretical or epistemic rationality is concerned with what it is rational to believe, and sometimes with rational degrees of belief, practical rationality is concerned with what it is rational to do, or intend or desire to do. This article raises some of the main issues relevant to philosophical discussion of the nature of rationality. Discussions of the nature of practical rationality and reason concern norms of choice, and it seems that if such norms are not arbitrary, arguments over what those norms are must ultimately be a theoretical matter. Furthermore, this article explores rationality's role in and relation to other domains of inquiry: psychology, gender, personhood, language, science, economics, law, and evolution.

McNaughton and Rawling present a view on which practical reasons are facts, such as the fact that the rubbish bin is full. This is a non-normative fact, but it is a reason for you to do something, namely take the rubbish out. They see rationality as a matter of consistency. And they see duty as neither purely a matter of rationality nor of practical reason: on the one hand, the rational sociopath is immoral; but, on the other, morality does not require that we always act on the weightiest moral reasons. McNaughton and Rawling criticize various forms of internalism, including Williams’s, and they tentatively propose a view of duty that is neither purely subjective in Prichard’s sense, nor purely objective.

In recent years the distinction between agent-relative and agent-neutral reasons has been taken by many to play a key role in distinguishing deontology from consequentialism. It is central to all universalist consequentialist theories that value is determined impersonally; the real value of any state of affairs does not depend on the point of view of the agent. No reference, therefore, to the agent or to his or her position in the world need enter into a consequentialist understanding of what makes an action right or wrong or morally permissible. Consequentialism thus provides an agent-neutral account of both the right and the good.
