What makes cases of pure risking sometimes wrong? There is a strong intuition that the wrongness of pure risking stands in an explanatory relationship with the wrongness of the non-risky act, other things being equal. Yet, we cannot simply take this for granted insofar as in cases of wrongful pure risking, the risked outcome fails to materialize. To this end, I motivate and develop an underexplored approach in the literature that I call Unificationism. According to the Unificationist account that I (...) |

This paper presents a new puzzle for limited aggregation. Unlike other recent puzzles, this one arises independently of the issue of rational aversion to risk. Some possible responses are laid out and explored. |

When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk‐avoidant risk function. This, in turn, has been claimed to require the use of a risk‐avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human survival. I (...) |

This thesis is about the moral reasons we have to do less than best. It consists of six chapters. Part I of the thesis proposes, extends, and defends reasons to do less than best. In Chapter One (“The Conditional Obligation”) I outline and reject two recent arguments from Joe Horton and Theron Pummer for the claim that we have a conditional obligation to bring about the most good. In Chapter Two (“Agglomeration and Agent-Relative Costs”) I argue that agent-relative costs can (...) |

When policymakers craft rules for use by the general public, they must take into account the ways in which their rules are likely to be misapplied. Should contractualists and rule consequentialists do the same when they search for rules whose general acceptance would be non-rejectable or ideal? I argue that these theorists face a dilemma. If they ignore the possibility of misapplication, they end up with an unrealistic view that rejects rules designed to protect us from others’ mistakes. On the (...) |

Autonomous systems are machines that can alter their behavior without direct human oversight or control. How ought we to program them to behave? A plausible starting point is given by the Reduction to Acts Thesis, according to which we ought to program autonomous systems to do whatever a human agent ought to do in the same circumstances. Although the Reduction to Acts Thesis is initially appealing, we argue that it is false: it is sometimes permissible to program a machine to (...) |

Many philosophers accept that, as well as having a right that others not harm us, we also have a right that others not subject us to a risk of harm. And yet, when we attempt to spell out precisely what this ‘right against risk imposition’ involves, we encounter a series of notorious puzzles. Existing attempts to deal with these puzzles have tended to focus on the nature of rights – but I propose an approach that focusses instead on the nature (...) |

I defend a weak version of the Pigou-Dalton principle for chances. The principle says that it is better to increase the survival chance of a person who is more likely to die rather than a person who is less likely to die, assuming that the two people do not differ in any other morally relevant respect. The principle justifies plausible moral judgements that standard ex post views, such as prioritarianism and rank-dependent egalitarianism, cannot accommodate. However, the principle can be justified (...) |

Many philosophers think that we should use a lottery to decide who gets a good to which two persons have an equal claim but which only one person can get. Some philosophers think that we should save identified persons from harm even at the expense of saving a somewhat greater number of statistical persons from the same harm. I defend a principled way of justifying both judgements, namely, by appealing to the decreasing marginal moral value of survival chances. I identify (...) |

According to the procreation asymmetry, we have strong pro tanto reason to do what prevents someone from coming into a miserable existence—an existence so bad that it would be rational to prefer having never been born—solely because it prevents them from coming into a miserable existence, but we do not have strong pro tanto reason to do what allows someone to come into a happy existence solely because it allows them to come into a happy existence. At best, the fact (...) |

Many people hold the constraint against doing harm, the view that the reason against doing harm is stronger than the reason against merely allowing harm, everything else being equal. Mogensen and MacAskill (2021) have recently argued that when considering indirect long-term consequences of our everyday behavior, the constraint against doing harm faces a problem: it has the absurd implication that we should do as little as possible in our lives. In this paper, I explore the view that, for behavior that (...) |

This thesis consists of a series of papers in population ethics: a subfield of normative ethics concerned with the distinctive issues that arise in cases where our actions can affect the identities or number of people of who ever exist. Each paper can be read independently of the others. In Chapter 1, I present a dilemma for Archimedean views in population axiology: roughly, those views on which adding enough good lives to a population can make that population better than any (...) |

Many real-world agents recognise that they impose harms by choosing to emit carbon, e.g., by flying. Yet many do so anyway, and then attempt to make things right by offsetting those harms. Such offsetters typically believe that, by offsetting, they change the deontic status of their behaviour, making an otherwise impermissible action permissible. Do they succeed in practice? Some philosophers have argued that they do, since their offsets appear to reverse the adverse effects of their emissions. But we show that (...) |

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) |

Particular persons have claims against being made worse off than they could have been. The literature, however, has focused primarily on only two-option cases; yet, these cases fail to capture all of the morally relevant factors, especially when a person’s existence is in question. This paper explores how to assess claims in multiple-option choice sets. We scrutinize the only extant proposal, offered by Michael Otsuka, which we call the Weakening View. In light of its problems, we develop an alternative: the (...) |

Ex-ante deontology is an attempt to combine deontological constraints on doing or intending harm with the idea that one should act in everyone’s interest if possible. I argue that ex-ante deontology has serious problems in cases where multiple decisions are to be made over time. I then argue that these problems force us to choose between commonsense deontological morality and a more consequentialist morality. I suggest that we should choose the latter. |

Brad Hooker’s rule-consequentialism and T.M. Scanlon’s contractualism have been some of the most debated ethical theories in normative ethics during the last twenty years or so. This article suggests that these theories can be compared at two levels. Firstly, what are the deep, structural differences between the rule-consequentialist and contractualist frameworks in which Hooker and Scanlon formulate their views? Secondly, what are the more superficial differences between Hooker’s and Scanlon’s formulations of these theories? Based on exploring these questions and several (...) |

In this article, we aim to map out the complexities which characterise debates about the ethics of vaccine distribution, particularly those surrounding the distribution of the COVID-19 vaccine. In doing so, we distinguish three general principles which might be used to distribute goods and two ambiguities in how one might wish to spell them out. We then argue that we can understand actual debates around the COVID-19 vaccine – including those over prioritising vaccinating the most vulnerable – as reflecting disagreements (...) |

Limited aggregation holds that we are only sometimes, not always, permitted to aggregate. Aggregation is permissible only when the harms and benefits are relevant to one another. But how should limited aggregation be extended to cases in which we are uncertain about what will happen? In this article, I provide a challenge to ex post limited aggregation. I reconstruct a precise version of ex post limited aggregation that relies on the notion of ex post claims. However, building a theory of (...) |

As machine learning informs increasingly consequential decisions, different metrics have been proposed for measuring algorithmic bias or unfairness. Two popular “fairness measures” are calibration and equality of false positive rate. Each measure seems intuitively important, but notably, it is usually impossible to satisfy both measures. For this reason, a large literature in machine learning speaks of a “fairness tradeoff” between these two measures. This framing assumes that both measures are, in fact, capturing something important. To date, philosophers have seldom examined (...) |

Many goods are distributed by processes that involve randomness. In lotteries, randomness is used to promote fairness. When taking social risks, randomness is a feature of the process. The losers of such decisions ought to be given a reason why they should accept the outcome. Surprisingly, good reasons demand more than merely equalex antechances. What is also required is a true statement of the form: ‘the result could easily have gone the other way and you could have been the winner’. (...) |

This volume collects selected papers delivered at the 15th Conference of the International Society for Utilitarian Studies, which was held at Karlsruhe Institute of Technology in July 2018. It includes papers dealing with the past, present, and future of utilitarianism – the theory that human happiness is the fundamental moral value – as well as on its applications to animal ethics, population ethics, and the future of humanity, among other topics. |

This is a chapter on contractualism for Ethical Theory in Global Perspective, edited by Michael Hemmingsen (SUNY Press). The chapter (i) outlines contractualism as an ethical theory, (ii) explains how it differs from classical utilitarianism, (iii) explores the differences between ex post and ex ante contractualism, and (iv) finally looks at two traditional objections to the view. |

Lockdown measures in response to the COVID-19 pandemic involve placing huge burdens on some members of society for the sake of benefiting other members of society. How should we decide when these policies are permissible? Many writers propose we should address this question using cost-benefit analysis, a broadly consequentialist approach. We argue for an alternative non-consequentialist approach, grounded in contractualist moral theorising. The first section sets up key issues in the ethics of lockdown, and sketches the apparent appeal of addressing (...) |

Is there any number of people you should save from paralysis rather than saving one person from death? Is there any number of people you should save from a migraine rather than saving one person from death? Many people answer ‘yes’ and ‘no’, respectively. The aim of partially aggregative moral views is to capture and justify combinations of intuitions like these. These views contrast with fully aggregative moral views, which imply that the answer to both questions is ‘yes’, and with (...) |

How should contractualists assess the permissibility of risky actions? Both main views on the question, ex ante and ex post, fail to distinguish between different kinds of risk. In this article, I argue that this overlooks a third alternative that I call “objective ex ante contractualism”. Objective ex ante substitutes discounting complaints by epistemic risk in favor of discounting by objective risk. I further argue in favor of this new view. Objective ex ante contractualism provides the best model of justifiability (...) |

This chapter presents a new argument for thinking of traditional ethical theories as methods that can be used in first-order ethics - as a kind of deliberation procedures rather than as criteria of right and wrong. It begins from outlining how ethical theories, such as consequentialism and contractualism, are flexible frameworks in which different versions of these theories can be formulated to correspond to different first-order ethical views. The chapter then argues that, as a result, the traditional ethical theories cannot (...) |

I discuss the trilemma that consists of the following three principles being inconsistent: 1. The Common Principle: if one distribution, A, necessarily brings a higher total sum of personal value that is distributed in a more egalitarian way than another distribution, B, A is more valuable than B. 2. (Weak) ex-ante Pareto: if one uncertain distribution, A, is more valuable than another uncertain distribution, B, for each patient, A is more valuable than B. 3. Pluralism about attitudes to risk (Pluralism): (...) |

The ex ante Pareto principle has an intuitive pull, and it has been a principle of central importance since Harsanyi’s defence of utilitarianism. The principle has been used to criticize and refine a range of positions in welfare economics, including egalitarianism and prioritarianism. But this principle faces a serious problem. I have argued elsewhere :303-323 2017) that the concept of ex ante Pareto superiority is not well defined, because its application in a choice situation concerning a fixed population can depend (...) |

You and I lead different lives. While we share a society and a world, our existence is separate from one another. You and I matter individually, by ourselves. My dissertation is about this simple thought. I argue that this simple insight, the separateness of persons, tells us something fundamental about morality. My dissertation seeks to answer how the separateness of persons matters. I develop a precise view of the demands of the separateness of persons. The separateness of persons imposes both (...) |

This essay begins by describing T.M. Scanlon’s contractualism according to which an action is right when it is authorised by the moral principles no one could reasonably reject. This view has argued to have implausible consequences with regards to how different-sized groups, non-human animals, and cognitively limited human beings should be treated. It has also been accused of being theoretically redundant and unable to vindicate the so-called deontic distinctions. I then distinguish between the general contractualist framework and Scanlon’s version of (...) |

Scanlonian contractualism rejects the consequentialist assumptions about morality, value, and rationality in virtue of which deontological constraints appear paradoxical. And yet, Jeffrey Brand-Ballard and Robert Shaver have claimed that it cannot succeed in defending the said restrictions. That is because they see Scanlon’s tie-breaking argument as threatening to justify aggregation in paradox of deontology cases. I argue that this claim rests upon a failure to appreciate contractualism’s relational character. Once we take this feature of the view into account, it becomes (...) |

Waiting time is widely used in health and social policy to make resource allocation decisions, yet no general account of the moral significance of waiting time exists. We provide such an account. We argue that waiting time is not intrinsically morally significant, and that the first person in a queue for a resource does not ipso facto have a right to receive that resource first. However, waiting time can and sometimes should play a role in justifying allocation decisions. First, there (...) |

According to contractualist theories in ethics, whether an action is wrong is determined by whether it could be justified to others on grounds no one could reasonably reject. Contractualists then think that reasonable rejectability of principles depends on the strength of the personal objections individuals can make to them. There is, however, a deep disagreement between contractualists concerning from which temporal perspective the relevant objections to different principles are to be made. Are they to be made on the basis of (...) |

According to psychological research, people are more eager to help identified individuals than unidentified ones. This phenomenon significantly influences many important decisions, both individual and public, regarding, for example, vaccinations or the distribution of healthcare resources. This paper aims at presenting definitions of various levels of identifiability as well as a critical analysis of the main philosophical arguments regarding the normative significance of the identifiability effect, which refer to: (1) ex ante contractualism; (2) fair distribution of chances and risks; (3) (...) |

Utilitarianism, it has been said, is not sensitive to the distribution of welfare. In making risky decisions for others there are multiple sensitivities at work. I present examples of risky decision-making involving drug allocations, charitable giving, breast-cancer screening and C-sections. In each of these examples there is a different sensitivity at work that pulls away from the utilitarian prescription. Instances of saving fewer people at a greater risk to many is more complex because there are two distributional sensitivities at work (...) |

Many of us believe (1) Saving a life is more important than averting any number of headaches. But what about risky cases? Surely: (2) In a single choice, if the risk of death is low enough, and the number of headaches at stake high enough, one should avert the headaches rather than avert the risk of death. And yet, if we will face enough iterations of cases like that in (2), in the long run some of those small risks of (...) |

A number of theorists have argued that Scanlon's contractualist theory both "gets around" and "solves" the non-identity problem. They argue that it gets around the problem because hypothetical deliberation on general moral principles excludes the considerations that lead to the problem. They argue that it solves the problem because violating a contractualist moral principle in one's treatment of another wrongs that particular other, grounding a person-affecting moral claim. In this paper, I agree with the first claim but note that all (...) |

This paper develops an account of rigour in the use of thought experiments in ethics. I argue that there are two separate challenges to be faced. The first is internal validity: is the thought experiment designed in a way that allows its readers to make judgements that are confident and free of bias about the hypothesis or point of principle that it aims to test? The second is external validity: to what extent do ethical judgements that are correct of the (...) |

Argues for the role of personal acquaintance in both love and concern for individuals, as such. The challenge is to say what personal acquaintance is and why it matters in the way it does. These questions are addressed through the work of Emmanuel Levinas. Topics include: the ethics of aggregation, the basis of moral standing, and the value of human life. |

Common-sense morality seems to tell us that a rescuer who can save either one individual or five other individuals from death has a duty to save the greater number. But contractualism, a moral theory on which principles must be justifiable to individuals, seems to imply that it is permissible to save the one. This is because a commitment to individual justification blocks the possibility of appealing to the aggregate amount of lives saved. Does contractualism really have this implication? If so, (...) |

How should we choose on behalf of people with different attitudes to risk? Simon Blessenohl has recently argued that this question poses a dilemma: it seems that sometimes we must choose either acts that everyone disprefers or else acts that are sure to turn out worse than some other act. In this article, I offer a complaints-centered account of how to take people’s attitudes to risk into consideration in our decision-making, and then I show that it provides a way out (...) |

In some views, philosophy’s glory days in bioethics are over. While philosophers were especially important in the early days of the field, so the argument goes, the majority of the work in bioethics today involves the “simple” application of existing philosophical principles or concepts, as well as empirical work in bioethics. Here, we address this view head on and ask: What is the role of philosophy in bioethics today? This paper has three specific aims: (1) to respond to skeptics and (...) |

How should we choose on behalf of groups of agents who violate expected utility theory by being risk averse or risk seeking? Unfortunately, we sometimes have to choose either acts that everyone disprefers or acts that are sure to turn out worse than another act. This observation is particularly troubling for risk-expected utility theorists: neither option sits comfortably with their view. |

Is there any number of people you should save from paralysis rather than saving one person from death? Is there any number of people you should save from a migraine rather than saving one person from death? Many people answer “yes” and “no,” respectively. The aim of partially aggregative moral views is to capture and justify combinations of intuitions like these. In this article, I develop a risk-based reductio argument that shows that there can be no adequate partially aggregative view. (...) |

After the cessation of conflict the majority of those involved in violations of international law will not be held criminally accountable. Rather, it is frequently the case that the bulk of perpetrators receive amnesty. Often, consequentialist considerations weigh heavily on the decision to grant amnesty. For instance, amnesties may be offered in order to generate aggregate security benefits in volatile post-conflict settings. My contention is that states cannot morally justify amnesties by appealing solely to the aggregate benefits they are expected (...) |

In a number of writings, Cass Sunstein has argued that we should use cost-benefit analysis as our primary approach to risk management, because cost-benefit analysis corrects for the cognitive biases that mar our thinking about risk. The paper critically evaluates this ‘cognitive argument for cost-benefit analysis’ and finds it wanting. Once we make distinctions between different cognitive errors and between different aspects of cost-benefit analysis, it becomes apparent that there are really two cognitive arguments, neither of which is successful as (...) |
