RésuméDuncan Macintosh a soutenu que l'idée d'une disposition à imposer des contraintes à la maximisation, qu'a défendue David Gauthier, fait face à un dilemme. Car si cette disposition est révocable, il n'est plus rationnel de s'y conformer quand vient le temps d'agir, et agir en conformité avec elle n'est done pas un comportement rationnel; mais si elle n'est pas révocable, agir en conformité avec elle n'est pas un comportement volontaire. Cet article se veut une réponse au dilemme de Macintosh. Je (...) recours pour cela à un type d'approche de l'intention rationnelle qui est — indépendamment — devenu de plus en plus saillant dans la littérature, et je soutiens que dans cette approche, une contrainte rationnelle et volontaire est possible.

David Gauthier claims that it can be rational to co-operate in a prisoner's dilemma if one has adopted a disposition constraining one's self from maximizing one's individual expected utility, i.e., a constrained maximizer disposition. But I claim cooperation cannot be both voluntary and constrained. In resolving this tension I ask what constrained maximizer dispositions might be. One possibility is that they are rationally acquired, irrevocable psychological mechanisms which determine but do not rationalize cooperation. Another possibility is that they are rationally (...) acquired preference-functions rationalizing cooperation as maximizing. I argue that if they are the first thing, then their adoption fails to make co-operation rational even if, as Gauthier also claims, actions are rational if they express rational dispositions. I then suggest that taking constrained maximizer dispositions to be things of the second sort would result in them being able to make co-operation rational, and that so-taking them therefore serves the bulk and spirit of Gauthier's larger claims, which I reconstruct accordingly.

Gauthier claims: (1) a non-maximizing action is rational if it maximized to intend it. If one intended to retaliate in order to deter an attack, (2) retaliation is rational, for it maximized to intend it. I argue that even on sympathetic theories of intentions, actions and choices, (1) is incoherent. But I defend (2) by arguing that an action is rational if it maximizes on preferences it maximized to adopt given one's antecedent preferences. (2) is true because it maximized to (...) adopt preferences on which it maximizes to retaliate. I thus save the theory that rational actions must maximize, and extend it into the rational criticism of preferences. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, and rational (...) decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

To the normal reasons that we think can justify one in preferring something, x (namely, that x has objectively preferable properties, or has properties that one prefers things to have, or that x's obtaining would advance one's preferences), I argue that it can be a justifying reason to prefer x that one's very preferring of x would advance one's preferences. Here, one prefers x not because of the properties of x, but because of the properties of one's having the preference (...) for x. So-revising one's preferences is rational in paradoxical choice situations like Kavka's Deterrence Paradox. I then try to meet the following objections: that this is stoicist, incoherent, bad faith; that it conflates instrumental and intrinsic value, gives wrong solutions to the problems presented by paradoxical choice situations, entails vicious regresses of value justification, falsifies value realism, makes valuing x unresponsive to x's properties, causes value conflict, conflicts with other standards of rationality, violates decision theory, counsels immorality, makes moral paradox, treats value change as voluntary, conflates first- and second-order values, is psychologically unrealistic, and wrongly presumes that paradoxical choice situations can even occur.

RÉSUMÉ: Une «situation de choix paradoxal» est une situation dans laquelle un agent connaîtrait davantage de succès en regard des préférences qu’il a effectivement, si ces préférences étaient différentes de ce qu’elles sont. Supposons que les agents rationnels ne choisissent pas à l’encontre de leurs préférences, que leur choix n’est déterminé que par ces préférences, et que leurs préférences intrinsèques ne changent pas de façon spontanée, automatique et directe sous l’influence de la critique rationnelle. Même dans de telles hypothèses, les (...) agents rationnels peuvent résoudre optimalement un éventail de situations de choix paradoxal au moyen de mécanismes qui les amènent à réviser leurs préférences. Dans cet article, je présente et défends un tel modèle de révision rationnelle des préférences. (shrink)
