Internal rewards are the psychological benefits one receives by performing certain other-regarding actions. Internal rewards include such benefits as the avoidance of guilt, the avoidance of painful memories, and the attainment of warm, fuzzy feelings. Despite the limitations of social psychology, Sober and Wilson believe that evolutionary theory can show that it is more likely for benevolent other-regarding motivational mechanisms to have evolved, thereby supporting the altruist’s claim. Here, I will argue for two related theses. First, if internal reward explanations (...) pose a problem for social psychology, then they also pose a problem for evolutionary theory. Second, there is no need to think that internal reward explanations pose a problem for altruists because these explanations either do not inform us about what our ultimate motives really are or they unreasonably define out of existence the possibility of altruism.

Some philosophers have tried to establish a connection between the normativity of instrumental rationality and the paradox presented by Lewis Carroll in his 1895 paper “What the Tortoise Said to Achilles.” I here examine and argue against accounts of this connection presented by Peter Railton and James Dreier before presenting my own account and discussing its implications for instrumentalism (the view that all there is to practical rationality is instrumental rationality). In my view, the potential for a Carroll-style regress just (...) shows us that since instrumental rationality involves a higher-order commitment to combine our willing an end with our taking the necessary means, it therefore cannot, on pain of regress, itself be added as a conjunct to one of the elements to be combined. This view does not support instrumentalism. (shrink)

This paper presents an objection to the view that intentions provide reasons and shows how this objection is also inherited by the more commonly accepted Tie-Breaker view, according to which intentions provide reasons only in tie-break situations. The paper also considers and rejects T. M. Scanlon's argument for the Tie-Breaker view and argues that philosophers might be drawn to accept the problematic Tie-Breaker view by confusing it with a very similar, unproblematic view about the relation between intentions and reasons in (...) tie-break situations.

Instrumental rationality prohibits one from being in the following state: intending to pass a test, not intending to study, and believing one must intend to study if one is to pass. One could escape from this incoherent state in three ways: by intending to study, by not intending to pass, or by giving up one’s instrumental belief. However, not all of these ways of proceeding seem equally rational: giving up one’s instrumental belief seems less rational than giving up an end, (...) which itself seems less rational than intending the means. I consider whether, as some philosophers allege, these “asymmetries” pose a problem for the wide-scope formulation of instrumental rationality. I argue that they do not. I also present an argument in favor of the wide-scope formulation. The arguments employed here in defense of the wide-scope formulation of instrumental rationality can also be employed in defense of the wide-scope formulations of other rational requirements.

Niko Kolodny has argued that some (local) rational requirements are narrow-scope requirements. Against this, I argue here that all (local) rational requirements are wide-scope requirements. I present a new objection to the narrow-scope interpretations of the four specific rational requirements which Kolodny considers. His argument for the narrow-scope interpretations of these four requirements rests on a false assumption, that an attitude which puts in place a narrow-scope rational requirement somewhere thereby puts in place a narrow-scope rational requirement everywhere. My argument (...) against Kolodny is analogous to arguments which use holism about reasons to defend moral particularism. (shrink)

Cognitivists about Practical Rationality argue that we can explain some of the (apparent) requirements of practical rationality by appealing to the requirements of theoretical rationality. First, they argue that intentions involve beliefs, and, second, they show how the theoretical requirements governing those involved beliefs can explain some of the practical requirements governing those intentions (or they show how these apparently practical requirements are actually theoretical requirements). This paper avoids the ongoing controversy about whether and how intentions involve beliefs and focuses (...) instead on this second part of the Cognitivist approach, where I think Cognitivism faces significant difficulties. I proceed by considering two attempts by Cognitivists to explain (apparent) requirements of practical rationality and I argue that neither of them succeed. (shrink)

It is generally agreed that many types of attitudinal incoherence are irrational, but there is controversy about why they are. Some think incoherence is irrational because it violates certain wide-scope conditional requirements, others (‘narrow-scopers’) that it violates narrow-scope conditional requirements. In his paper ‘The Scope of Rational Requirements’, John Brunero has offered a putative counter-example to narrow-scope views. But a narrow-scoper should reject a crucial assumption which Brunero makes, namely, the claim that we always violate conditional narrow-scope (...) requirements when we do not comply with them. I show how Brunero's objection can be met by denying this claim, and I provide independent arguments in favour of denying it. (shrink)

Rationality requires us to have certain propositional attitudes (beliefs, intentions, etc.) given certain other attitudes that we have. Carroll's Tortoise repeatedly shows up in this discussion. Following up on Brunero (2005, this journal), I ask what Carroll-style considerations actually prove. This paper rejects two existing suggestions, and defends a third.
