I argue that considerations about computational complexity show that all finite agents need characteristics like those that have been called epistemic virtues. The necessity of these virtues follows in part from the nonexistence of shortcuts, or efficient ways of finding shortcuts, to cognitively expensive routines. It follows that agents must possess the capacities – metavirtues –of developing in advance the cognitive virtues they will need when time and memory are at a premium.

Many philosophers think the distinctive function of deontic evaluation is to guide action. This idea is used in arguments for a range of substantive claims. In this paper, we entirely do one completely destructive thing and partly do one not entirely constructive thing. The first thing: we argue that there is an unrecognized gap between the claim that the function of deontic evaluation is to guide action and attempts to put that claim to use. We consider and reject four arguments (...) intended to bridge this gap. The interim conclusion is thus that arguments starting with the claim that the function of deontic evaluation is to guide action have a lacuna. The second thing: we consider a different tack for making arguments of this sort work. We sketch a methodology one could accept that would do the trick. Unfortunately, as we’ll explain, although this methodology would bridge the gap in arguments that put claims about the function of deontic evaluation to work, it would do so in a way that vitiates any interest we might have in such arguments. As an aside, we’ll also point out how epistemologists, who have recently become interested in the function of epistemic evaluation, appear to already recognize this fact. The conclusion is hence a dilemma: either arguments from deontic function to substance have a lacuna or such arguments lack teeth. (shrink)

It is widely thought that moral obligations are necessarily guidance giving. This supposed fact has been put to service in defence of the ‘ought-implies-can’ principle according to which one cannot be morally obligated to do the impossible, since impossible-to-satisfy obligations would not give guidance. It is argued here that the supposed fact is no such thing; moral obligations are not necessarily guiding giving, and so the ‘guidance argument’ for ought-implies-can fails. This is the result of no non-trivial condition being ‘luminous’.

Many moral theories incorporate the idea that when an action is wrong, it is wrong because that there was something else that the agent could and should have done instead. Most notable among these are consequentialist theories. According to consequentialism an action A is wrong if and only if there was another action B that the agent could have performed such that, if the agent had performed B instead of A, the consequences would have been better. Relatively little attention has (...) been given to the question of how to understand the meaning of ‘could have’ in this specific context. However, without an answer to this question, consequentialist theories fail to yield determinate verdicts about the deontic status of actions in real scenarios. It is here argued that the following conditional analysis provides the required answer and gives us the most plausible version of consequentialism: the agent could have done B instead of A if and only if, there is a decision such that had the agent made this decision, then she would have done B, and not A. Such a conditional analysis has been universally rejected as an analysis of the general meaning of ‘could have’, but we show that in the specific context of specifying the meaning of ‘could have’ in a consequentialist criterion of right and wrong action, all the standard objections to it fail.

It seems paradoxical to say that an action's normative status ‐ whether it is right, wrong, or obligatory ‐ depends on whether or not it is performed. In this paper, I shall argue that in itself this dependency is not paradoxical. I shall argue that we should not reject a normative theory just because it implies this kind of dependency. Not all dependencies of this kind are bad, or at least not bad enough to warrant wholesale rejection. Instead, we should (...) reject a theory when this dependency makes it a poor guide to action, in particular, when the dependency makes it impossible for agents to comply with the theory. (shrink)

The view that what one ought, or is obligated, to do is the best that one can do faces a problem even from the perspective of someone sympathetic with the view: there are cases of group action where, through lack of cooperation, the best that can be done is not done and yet where, it seems, each individual does the best that he or she can do. In this paper, various attempts to deal with this problem are criticized and then (...) a new solution is offered, one which requires "connected" individuals to be "transigent" relative to one another concerning possible group outcomes.

According to the procreation asymmetry there is no moral reason to create a new and foreseeably happy person just because this person will be happy, but there is however a moral reason against creating a new and foreseeably unhappy person just because this person will be unhappy. A common way to defend this conjunction of claims is by employing a so-called existence-requirement, according to which the happiness of a given person p in a world w depends on it being possible (...) to understand p as an existing person in w. The aim of this paper is to consider whether this existence-requirement strategy is compatible with other intuitions and convictions held in normative moral theory and populations ethics. This aim will be achieved by considering whether the existence-requirement strategy is compatible with three plausible desiderata for a solution to the procreation asymmetry. Although some solutions to some potential incompatibilities are suggested, the thesis that will be argued for is that every instance of the existence-requirement strategy is incompatible with at least one of the relevant desiderata. Where the common denominating incompatibility for all instances of the existence-requirement strategy is to be found in an inability to be sufficiently action-guiding. (shrink)

Coordination games show that all individuals can do what is right according to act‐consequentialism, even if they do not bring about the best outcome as a group. This creates two problems for act‐consequentialism. First, it cannot accommodate the intuition that there is some moral failure in these cases. Second, its formulation as a criterion of rightness conflicts with the underlying act‐consequentialist concern that the best outcome is brought about. The collectivist view solves these problems by holding that any group of (...) two or more individual agents, and only individual agents, is a collective agent who itself can act rightly or wrongly. When such a collective agent does what is wrong, there is a moral failure. When all collective agents do what is right, the best outcome is brought about. In this paper, I defend the collectivist view against the No Act Objection, according to which the doings of many so called disunified collectives are not acts. (shrink)
