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.

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.

Abstract: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 of which 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 accordance with such rules by the fear of social (...) and formal sanctions. On this way of thinking, rational individuals are condemned to having to settle for the “second-best” results that are thereby implied. This conclusion rests not only on an appeal to a consequentialist perspective, but also 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.Most people do not trust most other people, unmonitored, to honor obligations completely. Because of this they use substantial amounts of resources to specify the details of agreements, and to police them. Use of these resources … could be greatly reduced, if transacting parties would agree to honor the spirit of their agreement and simply shake hands. The resource saving to the two parties combined, from substituting this mode of “enforcing” agreements to those currently used, is clear. Why, then, does not this more efficient mode of transacting drive out the more costly methods through the normal competitive process? … The underlying rationale for this … is that it is privately profitable to engage in some degree of “cheating” on agreements, and to use resources to disguise this fact. — M. W. Reder, “The Place of Ethics in the Theory of Production”. (shrink)

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)

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.

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.

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)

McClennen addresses a fundamental dilemma facing the claim that it is rational to be guided by rules. Either the practical verdict issued by a rule is the same as that favored by the balance of reasons, in which case the rule is redundant or the verdicts differ, in which case the rule should be abandoned. McClennen argues that we can resolve this dilemma by revising our account of practical reasoning to accord with the prescriptions of a resolute choice (...) model. Agents in societies in which people resolutely follow, for example, a rule to keep their commitments to return favors fare better than agents in societies that lack a commitment mechanism or in which costs are incurred to enforce it.

This paper reviews six attempts to give cooperative solutions to Prisoners Dilemmas: symmetry (agents are in identical situations, so should choose the same way, so should both choose cooperation because that’s better for each), mechanism (each agent should delegate the decision to a machine which will choose cooperation for them provided the other does likewise), inducement (the agents should make a side bet which pays off only upon both cooperating), resolution (each agent should resolve to cooperate, then act on the (...) resolution), alternative principle (rationality requires not dominance reasoning and so defecting, but constrained maximization or resolution compliance or “sophisticated” choosing, and so cooperation), and preference revision (each agent should acquire conditional preferences to cooperate, then cooperate provided the other agent has acquired similar preferences). It distinguishes one-stage from two-stage games, as well as endogenously available solutions (ones available to agents in the circumstances of the game merely due to the nature of rationality) from solutions requiring exogenous devices. It contrasts Edward McClennen’s endogenous solution, which is some combination of resolution and alternative principle solution, with David Gauthier’s endogenous alternative principle solution. It argues that all have problems, ones best solved by the endogenous preference revision solution defended by Duncan MacIntosh. (shrink)

How can I give you a reason to believe what I tell you? I can influence the evidence available to you. Or I can simply invite your trust. These two ways of giving reasons work very differently. When a speaker tells her hearer that p, I argue, she intends that he gain access to a prima facie reason to believe that p that derives not from evidence but from his mere understanding of her act. Unlike mere assertions, acts of telling (...) give reasons directly. They give reasons by inviting the hearer’s trust. This yields a novel form of anti-reductionism in the epistemology of testimony. The status of testimony as a sui generis source of epistemic warrant is entailed by the nature of the act of telling. We can discover the nature of this illocution, and its epistemic role, by examining how it functions in the real world of human relations. (shrink)

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion -- assertion without (...) testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (shrink)

The biggest obstacle to understanding Aquinas's account of the soul may be the word “soul”. On hearing it, many people are prone to think of ghosts, ectoplasm, or Rene Descartes's notion of res cogitans. None of these has anything to do with the soul as Aquinas understands it. But even the standard one‐line Aristotelian‐Thomistic characterization of the soul as the form of the living body can too easily mislead. As is well known, the word “soul” is in Aristotelian‐Thomistic philosophy essentially (...) a technical term for the substantial form of a living thing. Material substances can be destroyed by other natural objects because they do have an inherent tendency toward corruption. A human being is the kind of substance which, in its mature and normal state, exhibits both the properties and causal powers characteristic of animality and those characteristic of rationality.

In the famous Correspondence with Clarke, which took place during the last year of Leibniz's life, Leibniz advanced several arguments purporting to refute the absolute theory of space and time that was held by Newton and his followers. The main aim of this book is to reassess Leibniz's attack on the Newtonian theory in so far as he relied on the principle of the identity of indiscernibles. The theological side of the controversy is not ignored but isolated and discussed in (...) the last three chapters, which deal with problems connected with the notions of omnipotence and omniscience.
