R. Jay Wallace argues that the normativity of instrumental rationality can be traced to the independent rational requirement to hold consistent beliefs. I present three objections to this view. John Broome argues that there is a structural similarity between the rational requirements of instrumental rationality and belief consistency. Since he does not reduce the former to the latter, his view can avoid the objections to Wallace’s view. However, we should not think Broome’s account explains the whole of instrumental rationality since agents with consistent intentions can still fail in their instrumental reasoning. This consideration makes Broome’s approach vulnerable to a line of criticism that both he and Wallace present against Christine Korsgaard’s conception of instrumental rationality.

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.

Cognitivists about Practical Rationality argue that we can explain some of the 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. 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 requirements of practical rationality and I argue that neither of them succeed.

Can a normative reason be understood as a kind of explanation? I here consider and argue against two important analyses of reasons as explanations. John Broome argues that we can analyze reasons in terms of the concepts of explanation and ought. On his view, reasons to ϕ are either facts that explain why one ought to ϕ (what he calls “perfect reasons”) or facts that play a for-ϕ role in weighing explanations (what he calls “pro tanto reasons”). I argue against Broome’s account of both perfect and pro tanto reasons. Other philosophers, including Joseph Raz, analyze reasons in terms of the concepts of explanation and good. On this view, some fact is a reason to ϕ if and only if that fact explains why ϕ-ing would be good in some respect, to some degree. This view avoids the objections to Broome’s view, but should be rejected since not all explanations of why ϕ-ing would be good constitute reasons to ϕ.

I consider Antti Kauppinen’s recent proposal for solving the wrong kind of reasons problem for fitting attitude analyses through an appeal to the verdicts of ideal subjects. I present two problems for Kauppinen’s treatment of a foreseen objection, and construct a counterexample to his proposal as it applies to the wrong kind of reasons to admire someone. I then show how to construct similar counterexamples to his proposal as it applies to the wrong kind of reasons for other attitudes, including guilt and shame.

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.

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.
