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.

Any adequate account of the distinction between consequentialist and deontological moral systems must take account of the central place given to constraints in the latter. Constraints place limits on what each of us may do in the pursuit of any goal, including the maximisation of the good. There is some debate, however, both over how constraints are to be characterised, and over the rationale for their inclusion in a moral system. Some authors view constraints as agent-relative: a constraint supplies an agent with an agent-relative reason to refrain from acting in the prohibited manner. A reason is agent-relative if it contains an ineliminable back-reference to the agent. On this characterisation, it is natural to suppose that constraints arise because of an agent’s concern with her own agency. There is perhaps, however, an alternative to this agent-focussed rationale: constraints, although characterised in terms of agent-relative reasons, might be best explained and defended via considerations of the potential victim of wrongdoing—yielding a victim- or patient-focussed rationale. Or, perhaps, constraints are not only best defended by a victim-focussed rationale; they are also best characterised by reference to the potential victim. In what follows, we advocate an agent-relative characterisation of, and an agent-focussed rationale for, constraints. We begin by developing a rigorous account of agent-focussed agent-relativity, before turning to consider patient-based approaches.

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

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

According to Newton, the goals of natural philosophy comprise quantitative generalizations and causal knowledge, the latter being paramount. Quantitative generalizations are sometimes explanatory, in psychology as elsewhere . However, in psychology, they are not explanatory when the human subject is considered qua bearer of psychological states , but only when she is considered qua physical system. In the former case quantitative generalizations are, rather, to be causally explained. In this sense, psychology may be closer to the Newtonian methodological mark than contemporary physics

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)

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)

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.
