This paper is about the idea of a moral distinction between doing harm and allowing harm to occurr. It discusses, and developes a general argument against, the version of the distinction often described as counterfactual, which I characterize in terms of making a moral difference between different ways of causing harm (in contrast to, e.g., the version famously discussed by Jonathan Bennett). The gist of the argument is that all variants of this version of the doing-allowing idea would have to (...) make factors out of the agent's control into wrong-making characteristics and that, therefore, this version violates a plausible extension of the principle that 'ought' implies 'can'.

In this paper, I argue for a new normative theory of rational choice under risk, namely expected comparative utility (ECU) theory. I first show that for any choice option, a, and for any state of the world, G, the measure of the choiceworthiness of a in G is the comparative utility (CU) of a in G—that is, the difference in utility, in G, between a and whichever alternative to a carries the greatest utility in G. On the basis of this (...) principle, I then argue that for any agent, S, faced with any decision under risk, S should rank his or her decision options (in terms of how choiceworthy they are) according to their comparative expected comparative utility (CECU) and should choose whichever option carries the greatest CECU. For any option, a, a’s CECU is the difference between its ECU and that of whichever alternative to a carries the greatest ECU, where a’s ECU is a probability‐weighted sum of a’s CUs across the various possible states of the world. I lastly demonstrate that in some ordinary decisions under risk, ECU theory delivers different verdicts from those of standard decision theory. (shrink)

Moral wrongness comes in degrees. On a consequentialist view of ethics, the wrongness of an act should depend, I argue, in part on how much worse the act's consequences are compared with those of its alternatives and in part on how difficult it is to perform the alternatives with better consequences. I extend act consequentialism to take this into account, and I defend three conditions on consequentialist theories. The first is consequentialist dominance, which says that, if an act has better (...) consequences than some alternative act, then it is not more wrong than the alternative act. The second is consequentialist supervenience, which says that, if two acts have equally good consequences in a situation, then they have the same deontic status in the situation. And the third is consequentialist continuity, which says that, for every act and for any difference in wrongness δ greater than zero, there is an arbitrarily small improvement of the consequences of the act which would, other things being equal, not change the wrongness of that act or any alternative by more than δ. I defend a proposal that satisfies these conditions. (shrink)

The demandingness of a moral prescription is generally understood exclusively in terms of the welfare costs involved in complying with that prescription. I argue that psychological difficulty is a second aspect of demandingness, whose relevance cannot be reduced to that of welfare costs. Appeal to psychological difficulty explains intuitive verdicts about the permissibility of favouring oneself over others, favouring loved ones over strangers, and favouring one’s short-term good over one’s long-term good. There are also significant implications for the morality of (...) addressing severe global poverty. (shrink)
