This is a major contribution to the theory of rational choice which will be of particular interest to philosophers and economists. The author sets out the foundations of rational choice, and then sketches a dynamic choice framework in which principles of ordering and independence follow from a number of apparently plausible conditions. However, there is potential conflict among these conditions, and when they are weakened to avoid it the usual foundations of rational choice no longer prevail. The thrust of the (...) argument is to suggest that the theory of rational choice is less deterministic than many suppose. (shrink)

In Morals By Agreement, David Gauthier concludes that under certain conditions it is rational for an agent to be disposed to choose in accordance with a fair cooperative scheme rather than to choose the course of action that maximizes his utility. This is only one of a number of important claims advanced in that book. In particular, he also propounds a distinctive view concerning what counts as a fair cooperative arrangement. The thesis concerning the rationality of adopting a cooperative disposition (...) is, however, logically independent of his substantive view of a fair cooperative scheme and is itself central to the project as a whole. Gauthier's concern is to establish that certain moral principles are those that fully rational, self-interested persons would agree to take as regulative of their dealings with one another – that a contractarian approach, in this sense, can provide an adequate basis for a theory of morality.

Michael Bratman''s restricted two-tier approach to rationalizing the stability of intentions contrasts with an alternative view of planning, for which all of the following claims are made: (a) it shares with Bratman''s restricted two-tier approach the virtue of reducing the magnitude of Smart''s problem; (2) it, rather than the unrestricted two-tier approach, is what is argued for in McClennen (1990); (3) there does not appear to be anything in the central analysis that Bratman has provided of plans and intentions (...) (both in his book,Intention, Plans, and Practical Reason, and in the article Planning and the Stability of Intention) that precludes his adopting this alternative approach; and (4) it is an approach that neither requires nor encourages any distinction between the standards appropriate to artificial and to human intelligence.

One of the more obscure arguments for Rawls’ difference principle dubbed ‘the Pareto argument for inequality’ has been criticised by G. A. Cohen (1995, 2008) as being inconsistent. In this paper, we examine and clarify the Pareto argument in detail and argue (1) that justification for the Pareto principles derives from rational selfinterest and thus the Pareto principles ought to be understood as conditions of individual rationality, (2) that the Pareto argument is not inconsistent, contra Cohen, and (3) that the (...) kind of bargaining model required to arrive at the particular unequal distribution that the difference principle picks out is a model that is not based on bargaining according to one’s threat advantage.

In (1991), Meinwald initiated a major change of direction in the study of Plato’s Parmenides and the Third Man Argument. On her conception of the Parmenides , Plato’s language systematically distinguishes two types or kinds of predication, namely, predications of the kind ‘x is F pros ta alla’ and ‘x is F pros heauto’. Intuitively speaking, the former is the common, everyday variety of predication, which holds when x is any object (perceptible object or Form) and F is a property (...) which x exemplifies or instantiates in the traditional sense. The latter is a special mode of predication which holds when x is a Form and F is a property which is, in some sense, part of the nature of that Form. Meinwald (1991, p. 75, footnote 18) traces the discovery of this distinction in Plato’s work to Frede (1967), who marks the distinction between pros allo and kath’ hauto predications by placing subscripts on the copula ‘is’.

Contemporary discussions of the positive relation between rational choice and moral theory are a special case of a much older tradition that seeks to show that mutual agreement upon certain moral rules works to the mutual advantage, or in the interests, of those who so agree. I make a few remarks about the history of discussions of the connection between morality and self-interest, after which I argue that the modern theory of rational choice can be naturally understood as a continuation (...) of this older tradition. I then go on to argue for a controversial three-fold thesis: (1) that grounding a theory of morality in terms of rational self-interest is the only epistemologically respectable way to proceed with the justification of moral principles; (2) that despite this, most of the contemporary explorations of rational choice foundations for moral principles do not work—that the models of rational choice to which they appeal yield less than the substantial results that they are intended to yield; but (3) that if one rethinks just what it means to be rational, one can find in fact a promising way to connect the two—specifically through the development of a theory of genuinely cooperative activity.

The kind of commitment to moral rules that characterizes effective interaction between persons in, among others places,manufacturing and commercial settings is characteristically treated by economists and game theorists as a public good, the securing ofwhich requires the expenditure of scarce resources on surveillance and enforcement mechanisms. Alternatively put, the view is that,characteristically, rational persons cannot voluntarily guide their choices by rules, but can only be goaded into acting in accordancewith such rules by the fear of social and formal sanctions. On (...) this way of thinking, rational individuals are condemned to having to settlefor the "second-best" results that are thereby implied. This conclusion rests not only on an appeal to a consequentialist perspective, butalso a separability principle. Against this, it is argued that consequentialism itself offers a basis for the rejection of the separability principle, and a defense of the thesis that, for a wide range of realistic cases, being disposed to voluntarily guide one's choice by rules (on the condition that others can be expected to do so as well) is a necessary condition of engaging in rational interaction.

The Nash-Harsanyi theory of bargaining is usually taken as the correct theory of rational bargaining, and, as such, as the correct theory for the basic political contract for a society. It grafts a theory of cooperation to a base that essentially articulates the perspective of non-cooperative interaction. The resultant theory is supposed make clear how rational bargaining can fully realize the mutual gains that cooperation can make possible. However, its underlying commitment to the concepts of non-cooperative interaction renders this doubtful. (...) I argue for an alternative theory—the theory of Full Cooperation—that avoids this difficulty. As applied to bargaining over the basic political contract, it calls for the selection of the most egalitarian of the Strictly Pareto-Optimal outcomes. This is essentially a version of Rawls’ principle of Justice as Fairness, but it is derived, unlike Rawls’ theory, without appeal to a problematic theory of individual decision-making behind the veil of ignorance. It also provides an alternative basis for what Hart calls the Principle of Mutual Restrictions, and what Rawls’ calls the Duty of Fair Play. (shrink)

This is the first book in modern times that makes sense of the Nicomachean Ethics in its entirety as an interesting philosophical argument, rather than as a compilation of relatively independent essays. In Taking Life Seriously Francis Sparshott expounds Aristotle's Nicomachean Ethics as a single continuous argument, a chain of reasoned exposition on the problems of human life. He guides the reader through the whole text passage by passage, showing how every part of it makes sense in the light (...) of what has gone before, as well as indicating problems in Aristotle's argument. No knowledge of Greek is required. When the argument does depend on the precise wording of the Greek text, translations and explanatory notes are provided, and there is a glossary of Greek terms. Sparshott offers insightful and useful criticism, making Taking Life Seriously the best available companion to a first reading of the Ethics. (shrink)

I want to extend here a line of reasoning that I pursued in Rationality and Dynamic Choice . In that book I argued that the standard Bayesian model of expected-utility reasoning needs to be revised to accommodate a capacity, on the part of rational decision-makers, to effectively coordinate with their own future selves — to be guided by plans that they have deliberately adopted. I also suggested that an analogous line of reasoning might be employed to show that rational agents (...) could engage in rule-governed coordination of their choices with one another to a greater extent than the standard theory would seem to admit. It is this suggestion that I now want to explore more fully in the present paper. It is not that the standard theory denies the possibility of such coordination. On that account, however, coordination can only be achieved by the adoption of an effective enforcement system. Since, however, any enforcement scheme requires the expenditure of scarce resources, the standard theory seems committed to the view that rational agents can achieve only a second best outcome. It is worth considering whether thoroughly rational persons who know each other to be such might not do better than this. It is also the case that the process whereby individuals come to agreement on the terms of their coordination schemes is conceived as driven essentially by non-cooperative considerations, specifically the relative bargaining power or threat advantage of the participants. Bargaining outcomes based on this principle, however, tend to generate mutually disadvantageous conflict, and thus there are greater costs yet to be borne by “rational” interacting agents. I shall have to leave the exploration of this second problem to another occasion, however. (shrink)
