The book develops, defends, and applies an account of weighing reasons to resolve various issues in ethics. It tells you everything you ever wanted to know about weighing reasons and probably a lot of stuff you didn't want to know too. The excerpt provided here is the Table of Contents, the Introduction, and Chapter 1.

I defend the exclusionary power of political directives. The prevailing account, which I call the additive account, holds that a legitimate directive only provides a pro tanto obligation for subjects to comply. I show that it falls into a Goldilocks dilemma, giving either insufficient or excessive weight to these obligations. Pace the additive account, I argue that a legitimate directive not only gives subjects a pro tanto reason to comply but also excludes all the reasons bearing on its justifiability regarding (...) subjects’ actions as required by the directive. Unlike Raz, who grounds the exclusionary power of legitimate directives on authorities’ supposedly superior epistemic competence, I justify it by drawing on Kantian political philosophy, which grants states a unique moral standing to make coercive decisions on behalf of their citizenry as a solution to the problem of unilateralism.

One way of being responsible for an action is being praiseworthy for it. But what is the “praise” of which the praiseworthy agent is worthy? This paper provides a survey of answers to this question, i.e. a survey of possible accounts of praise’s nature. It then presents an overview of candidate norms governing our responses of praise. By attending to praise’s nature and appropriateness conditions, we stand to acquire a richer conception of what it is to be, and to regard (...) another as, a responsible agent. (shrink)

There are plenty of classic paradoxes about conditional obligations, like the duty to be gentle if one is to murder, and about “supererogatory” deeds beyond the call of duty. But little has been said about the intersection of these topics. We develop the first general account of conditional supererogation, with the power to solve familiar puzzles as well as several that we introduce. Our account, moreover, flows from two familiar ideas: that conditionals restrict quantification and that supererogation emerges from a (...) clash between justifying and requiring reasons. (shrink)

As well as disagreeing about how much one should donate to charity, moral theories also disagree about where one should donate. In light of this disagreement, how should the morally uncertain philanthropist allocate her donations? In many cases, one intuitively attractive option is for the philanthropist to split her donations across all of the charities that are recommended by moral views in which she has positive credence, with each charity’s share being proportional to her credence in the moral theories that (...) recommend that particular charity. Despite the fact that something like this approach is already being used by real-world philanthropists to distribute billions of dollars of donations, it is not supported by any of the approaches to moral uncertainty that have been proposed thus-far in the philosophical literature. In this paper, we will develop a bargaining-based approach to moral uncertainty that honors the proportionality intuition in favor of splitting one’s donations. We also show how this bargaining-based approach has several further advantages over the best alternative proposals. (shrink)
