Greater public awareness of the occurrence of sexual assault has led to the creation of mobile phone apps designed to facilitate consent between sexual partners. These apps exhibit serious practical shortcomings in realistic contexts; however, in this paper I consider the hypothetical case in which these practical shortcomings are absent. The prospect of this viable consent app creates an interesting challenge for consequentialism – one that is comparable to the objection that the theory justifies killing innocent persons to prevent large (...) numbers of less serious harms like experiencing brief, painful headaches. I outline and reject the most straightforward way for consequentialists to address this challenge, and I argue that the empirical calculations at stake reveal something rarely appreciated: consequentialists ought to sometimes favour reinforcing deontological constraints in common-sense morality rather than seeking to undermine them.

In this thesis, I discuss the aggregation problem for T. M. Scanlon’s “contractualism”. I argue that Scanlonian contractualists have the following two options when it comes to the aggregation problem. First, they can choose to limit aggregation directly via a specific version of the Relevance View, “Sequential Claims-Matching”. Second, Scanlonian contractualists can adopt a so-called “mixed solution” of which I propose a specific version. My mixed solution does not limit aggregation. Rather, it either avoids some of the counterintuitive results in (...) certain cases, or at least makes these same results look a lot less counterintuitive by putting them into perspective thanks to a plausible plurality of precisely specified values. The stakes between these two options are as follows. The first option justifies Scanlon’s intuition in one vs. many cases of which his “World Cup Case” is one example, but it comes at the cost of a seemingly quite limited range of application: any version of the Relevance View only works in cases in which we have no more than two groups of competing claimants. The second option has the exact opposite implications: my mixed solution cannot justify Scanlon’s intuition in one vs. many cases, but it could be applied to any case with any number of groups of competing claimants. In this choice between pre-theoretical intuition and feasibility, I would urge Scanlonian contractualists to choose feasibility. (shrink)

More than 1.2 million people are killed annually in road crashes all over the world, and still it seems that philosophers and, perhaps more importantly, professional ethicists have not devoted thought to the many moral issues that road traffic was bound to create. This article tries to understand why road ethics is all but ignored by philosophers and ethicists, and makes a plea for a change. By exploring ethically the traffic safety problem of speeding it will be shown that ethical (...) analysis is not only appropriate but mandatory. (shrink)

One widely used method for allocating health care resources involves the use of cost-effectiveness analysis (CEA) to rank treatments in terms of quality-adjusted life-years (QALYs) gained. CEA has been criticized for discriminating against people with disabilities by valuing their lives less than those of non-disabled people. Avoiding discrimination seems to lead to the ’QALY trap’: we cannot value saving lives equally and still value raising quality of life. This paper reviews existing responses to the QALY trap and argues that all (...) are problematic. Instead, we argue that adopting a moderate form of prioritarianism avoids the QALY trap and disability discrimination. (shrink)

This thesis discusses the possibility of limited moral trade-offs between different people’s welfare. In chapter 2, I introduce the two central limited trade-off conditions. First, according to minimal infinite superiority, significantly benefiting one person matters more than slightly benefiting each of any number of better-off people. Second, according to minimal finite superiority, significantly benefiting many people matters more than slightly benefiting one person. I consider both axiological and deontic interpretations of these conditions. However, I explain why none of the simple (...) classic moral principles—the simple total and the maximin principles—satisfy both conditions. Furthermore, in chapter 3, I strengthen several proved impossibility results according to which no moral theory satisfies weak interpretations of these central trade-off conditions and several other seemingly plausible minimal conditions. I show that giving up structural axiological and deontic conditions is not a satisfactory solution to these paradoxes. In chapter 4, I discuss the modification of a background assumption of these impossibility results on the measurement of welfare. I show that, given a modification that allows for lexicographically ordered welfare components, a total principle can satisfy all the conditions of the impossibility results. However, I argue that such a modification is not entirely satisfactory because it does not apply in certain instances of the paradoxes. In chapter 5, I discuss a further weakening of minimal infinite superiority. However, I show that a suggested possibility result based on this modification is not valid and that further moral conditions, such as minimal finite superiority, need to be modified. Moreover, I argue that these modified conditions and the principle suggested in the possibility proof—a minimax complaint principle—do not capture the basic idea of the two central limited trade-off conditions sufficiently well. In chapter 6, I argue that other principles suggested for the task—the total claim principles—share the same fate as the simple total principles or the minimax complaint principle. In chapter 7, I propose new principles that take their structural roots from voting theory. I show that, in contrast to the other principles discussed, these principles give plausible verdicts where the other principles failed. Finally, in chapter 8, I consider possible objections levelled against this proposal, and I suggest solutions and avenues for future research. (shrink)
