Providing meaningful and actionable explanations for end-users is a situated problem requiring the intersection of multiple disciplines to address social, operational, and technical challenges. However, the explainable artificial intelligence community has not commonly adopted or created tangible design tools that allow interdisciplinary work to develop reliable AI-powered solutions. This paper proposes a formative architecture that defines the explanation space from a user-inspired perspective. The architecture comprises five intertwined components to outline explanation requirements for a task: (1) the end-users’ mental models, (...) (2) the end-users’ cognitive process, (3) the user interface, (4) the Human-Explainer Agent, and (5) the agent process. We first define each component of the architecture. Then, we present the Abstracted Explanation Space, a modeling tool that aggregates the architecture’s components to support designers in systematically aligning explanations with end-users’ work practices, needs, and goals. It guides the specifications of what needs to be explained (content: end-users’ mental model), why this explanation is necessary (context: end-users’ cognitive process), to delimit how to explain it (format: Human-Explainer Agent and user interface), and when the explanations should be given. We then exemplify the tool’s use in an ongoing case study in the aircraft maintenance domain. Finally, we discuss possible contributions of the tool, known limitations or areas for improvement, and future work to be done. (shrink)

This book elucidates the theoretical structure and scope of interpersonal and intra-personal aggregation--a trade-off between benefits to a group of individuals and losses to another group of individuals--and defends a form of aggregation -- formal aggregation -- that resolves a variety of outstanding problems arising from the conventional understanding of aggregation, including the Number Problem concerning the moral relevance of the number of individuals.

Is an outcome where many people are saved and one person dies better than an outcome where the one is saved and the many die? According to the standard utilitarian justification, the former is better because it has a greater sum total of well-being. This justification involves a controversial form of moral aggregation, because it is based on a comparison between aggregates of different people's well-being. Still, an alternative justification—the Argument for Best Outcomes—does not involve moral (...) class='Hi'>aggregation. I extend the Argument for Best Outcomes to show that any utilitarian evaluation can be justified without moral aggregation. (shrink)

Medical devices with built-in bias can both result from, and contribute to, harmful systemic racial oppression—a point that Liao and Carbonell (2023) argue convincingly in the target article of thi...

In this article, I describe how gender bias can affect the design, testing, clinical trials, regulatory approval, and clinical use of implantable devices. I argue that bad outcomes experienced by women patients are a cumulative consequence of small biases and inattention at various points of the design, testing, and regulatory process. However, specific instances of inattention and bias can be difficult to identify, and risks are difficult to predict. This means that even if systematic gender bias in implant design is (...) an ethical issue, it is one with no clearly blameworthy player. From a practical perspective, there is no single obvious point at which to intervene. Philosophers working in other areas have explored structurally similar moral problems—sometimes referred to as “moral aggregation problems”—such as the type of environmental harm caused by small actions of many players. I describe key features of these type of problems and strategies to address them. I then draw on these to suggest an approach to gender bias in medical implant design and use. (shrink)

:Preference-aggregation problems arise in various contexts. One such context, little explored by social choice theorists, is metaethical. ‘Ideal-advisor’ accounts, which have played a major role in metaethics, propose that moral facts are constituted by the idealized preferences of a community of advisors. Such accounts give rise to a preference-aggregation problem: namely, aggregating the advisors’ moral preferences. Do we have reason to believe that the advisors, albeit idealized, can still diverge in their rankings of a given set (...) of alternatives? If so, what are the moral facts when the advisors do diverge? These questions are investigated here using the tools of Arrovian social choice theory. (shrink)

I begin by reconsidering the arguments of John Taurek and Elizabeth Anscombe on whether the number of people we can help counts morally. I then consider arguments that numbers should count given by F. M. Kamm and Thomas Scanlon, and criticism of them by Michael Otsuka. I examine how different conceptions of the moral method known as pairwise comparison are at work in these different arguments and what the ideas of balancing and tie-breaking signify for decision-making in various types (...) of cases. I conclude by considering how another moral method that I call virtual divisibility functions and what it helps reveal about an argument by Otsuka against those who do not think numbers count.

For aggregative theories of moral value, it is a challenge to rank worlds that each contain infinitely many valuable events. And, although there are several existing proposals for doing so, few provide a cardinal measure of each world's value. This raises the even greater challenge of ranking lotteries over such worlds—without a cardinal value for each world, we cannot apply expected value theory. How then can we compare such lotteries? To date, we have just one method for doing so (...) (proposed separately by Arntzenius, Bostrom, and Meacham), which is to compare the prospects for value at each individual location, and to then represent and compare lotteries by their expected values at each of those locations. But, as I show here, this approach violates several key principles of decision theory and generates some implausible verdicts. I propose an alternative—one which delivers plausible rankings of lotteries, which is implied by a plausible collection of axioms, and which can be applied alongside almost any ranking of infinite worlds.

This article applies the tools of experimental philosophy to the ongoing debate about both the theoretical viability and the practical import of partially aggregative moral theories in distributive ethics. We conduct a series of three experiments (N=383): First, we document the widespread occurrence of the intuitions that motivate this position. Our study then moves beyond establishing the existence of partially aggregative intuitions in two dimensions: First, we extend experimental work in such a way as to ascertain which amongst existing (...) versions of partial aggregation (localised vs. global) chimes more fully with moral common sense. Specifically, we document how, in tie-breaking cases, ‘irrelevant goods’ judgments (Kamm) are just as robust as the original aggregative/non-aggregative pair of judgments that constitute partial aggregation. Second, by pairing laypeople’s moral judgments in standard cases with their intuitions about the limits of permissible self-prioritisation, we investigate whether one prominent explanation of why irrelevant claims may not be aggregated (Voorhoeve’s ‘personal prerogative’ argument) can be said to underpin people’s intuitions about the (ir)relevance relation of claims in conflict cases. We close with a discussion of our findings’ practical and theoretical import and highlight avenues for future research. (shrink)

Aggregative moral theories face a series of devastating problems when we apply them in a physically realistic setting. According to current physics, our universe is likely _infinitely large_, and will contain infinitely many morally valuable events. But standard aggregative theories are ill-equipped to compare outcomes containing infinite total value so, applied in a realistic setting, they cannot compare any outcomes a real-world agent must ever choose between. This problem has been discussed extensively, and non-standard aggregative theories proposed to overcome (...) it. This paper addresses a further problem of similar severity. Physics tells us that, in our universe, how remotely in time an event occurs is _relative_. But our most promising aggregative theories, designed to compare outcomes containing infinitely many valuable events, are sensitive to how remote in time those events are. As I show, the evaluations of those theories are then relative too. But this is absurd; evaluations of outcomes must be absolute. So we must reject such theories. Is this objection fatal for all aggregative theories, at least in a relativistic universe like ours? I demonstrate here that, by further modifying these theories to fit with the physics, we can overcome it. (shrink)

Suppose you found that the universe around you was infinite—that it extended infinitely far in space or in time and, as a result, contained infinitely many persons. How should this change your moral decision-making? Radically, it seems, according to some philosophers. According to various recent arguments, any moral theory that is ’minimally aggregative’ will deliver absurd judgements in practice if the universe is (even remotely likely to be) infinite. This seems like sound justification for abandoning any such theory. (...) -/- My goal in this thesis is simple: to demonstrate that we need not abandon minimally aggregative theories, even if we happen to live in an infinite universe. I develop and motivate an extension of such theories, which delivers plausible judgements in a range of realistic cases. I show that this extended theory can overcome key objections—both old and new—and that it succeeds where other proposals do not. With this proposal in hand, we can indeed retain minimally aggregative theories and continue to make moral decisions based on what will promote the good. (shrink)

How might we extend aggregative moral theories to compare infinite worlds? In particular, how might we extend them to compare worlds with infinite spatial volume, infinite temporal duration, and infinitely many morally valuable phenomena? When doing so, we face various impossibility results from the existing literature. For instance, the view we adopt can endorse the claim that worlds are made better if we increase the value in every region of space and time, or that they are made better if (...) we increase the value obtained by every person. But they cannot endorse both claims, so we must choose. In this paper I show that, if we choose the latter, our view will face serious problems such as generating incomparability in many realistic cases. Opting instead to endorse the first claim, I articulate and defend a spatiotemporal, expansionist view of infinite aggregation. Spatiotemporal views such as this do face some difficulties, but I show that these can be overcome. With modification, they can provide plausible comparisons in cases that we care about most.

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 headache rather than saving one person from death? Many people answer ‘yes’ and ‘no’, respectively. They therefore accept a partially aggregative moral view. Patrick Tomlin has recently argued that the most promising partially aggregative views in the literature have implausible implications in certain cases in which there are additions or subtractions (...) to the groups of people that we can save. Several philosophers have begun responding to this argument by developing partially aggregative views that avoid the relevant implications. In this paper, I extend Tomlin’s argument to create a dilemma that no partially aggregative view can avoid. I conclude that we should accept a fully aggregative moral view. (shrink)

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.

In this article, I develop a risk-based reductio argument that shows that there can be no adequate partially aggregative (...) view. I then argue that the only plausible response to this reductio is to accept a fully aggregative view. (shrink)

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.

These views contrast with fully aggregative moral views, which imply that the answer to both questions is ‘yes’, (...) and with non-aggregative moral views, which imply that the answer to both questions is ‘no’. In this paper, I review the most natural and influential ways of developing partially aggregative views and explain the main problems they face. (shrink)

The Moral Foundations of Trust seeks to explain why people place their faith in strangers, and why doing so matters. Trust is a moral value that does not depend upon personal experience or on interacting with people in civic groups or informal socializing. Instead, we learn to trust from our parents, and trust is stable over long periods of time. Trust depends on an optimistic world view: the world is a good place and we can make it better. (...) Trusting people are more likely to give through charity and volunteering. Trusting societies are more likely to redistribute resources from the rich to the poor. Trust has been in decline in the United States for over 30 years. The roots of this decline are traceable to declining optimism and increasing economic inequality, which Uslaner supports by aggregate time series in the United States and cross-sectional data across market economies.

It is plausible to claim that it is morally worse to kill an innocent person than to give any number of people a mild one‐hour headache. Alaistar Norcross has argued that consequentialists, at least, should reject this claim. According to him, any harm that can befall a person can be morally outweighed by a sufficient number of very small harms. He gives a general argument for this view, and tries to show, by means of an argument from analogy, that it (...) is less counter‐intuitive than it appears. I show that his main argument relies on a false assumption, and argue that the purported analogy is dubious. (shrink)

Many philosophers have discussed problems of additive aggregation across lives. In this article, I suggest that anti-additive aggregationist principles sometimes apply within lives, as well as between lives, and hence that we should reject a widely accepted conception of individual self-interest. The article has eight sections. Section I is introductory. Section II offers a general account of aggregation. Section III presents two examples of problems of additive aggregation across lives: Derek Parfit's Repugnant Conclusion, and my Lollipops for (...) Life Case Section IV suggests that many may have misdiagnosed the source and scope of anti-additive aggregationist considerations, due to the influence of Rawls's and Nozick's claims about the separateness of individuals. Accordingly, many leave Sidgwick's conception of self-interest—which incorporates an additive aggregationist approach to valuing individual lives—unchallenged. Section V suggests that the separateness of individuals may have led some to conflate the issues of compensation and moral balancing. Section VI argues that an additive aggregationist approach is often deeply implausible for determining the overall value of a life. Section VII discusses a Single Life Repugnant Conclusion, first considered by McTaggart. Section VIII concludes with a summary, and a brief indication of work remaining. (shrink)

Consider the Strong Beneficence Principle (SBP): Persons of affluent means ought to give to those who might fail basic human subsistence until the point at which they must give up something of comparable moral importance. This principle has been the subject of much recent discussion. In this paper, I argue that no coherent interpretation of SBP can be found. SBP faces an interpretive trilemma, each horn of which should be unacceptable to fans of SBP; SBP is either (a) so (...) strong as to be patently absurd; (b) implausible given its acceptance of a form of numbers skepticism; (c) drained of all its demanding force. In the conclusion, I show how the problems with SBP generalize to all similarly demanding principles of beneficence. (shrink)

Some of the most pressing contemporary social problems result from the amalgamation of a mass of actions that are not intentionally coordinated. Although these essentially aggregative harms are foreseeable, it is unclear what moral duties individuals have with regards to them. This paper offers a new analysis of these problems and uses a nonideal contractualist approach to argue in favour of two kinds of duties for individuals. Collectivization duties that require individuals to act responsively with a view to ensuring (...) that there are effective governance agents that reliably, fairly, and efficiently prevent these outcomes in the long-term and duties of restraint that require individuals to avoid action of a kind that is likely to come together with other actions to cause serious EAH in the immediate future when restraint with regards to actions of this kind could help prevent the outcome from occurring.

Limited Aggregation is the view that when there are competing moral claims that demand our attention, we should sometimes satisfy the largest aggregate of claims, depending on the strength of the claims in question. In recent years, philosophers such as Patrick Tomlin and Alastair Norcross have argued that Limited Aggregation violates a number of rational choice principles such as Transitivity, Separability, and Contraction Consistency. Current versions of Limited Aggregation are what may be called Comparative Approaches because (...) they involve assessing the relative strengths of various claims. In this paper, we offer a non-comparative version of Limited Aggregation, what we call the Threshold Approach. It states that there is a non-relative threshold that separates various claims. We demonstrate that the Threshold Approach does not violate rational choice principles such as Transitivity, Separability, and Contraction Consistency, and we show that potential concerns regarding such a view are surmountable.

Patient preference predictors aim to solve the moral problem of making treatment decisions on behalf of incapacitated patients. This commentary on a case of an unrepresented patient at the end of life considers 3 related problems of such predictors: the problem of restricting the scope of inputs to the models (the “scope” problem), the problem of weighing inputs against one another (the “weight” problem), and the problem of multiple reasonable solutions to the scope and weight problems (the “multiple reasonable (...) models” problem). Each of these problems poses challenges to reliably implementing patient preference predictors in important, high-stakes health care decision making. This commentary also suggests a way forward.

Human and animal interests are often in conflict. In many situations, however, it is unclear how to evaluate and weigh competing human and animal interests, as the satisfaction of the interests of one group often inevitably occurs at the expense of those of the other group. Human-animal conflicts of this kind give rise to ethical questions. If animals count morally for their own sake, then we must ask in which cases the satisfaction or frustration of the interests of humans and (...) animals in conflict situations is justified or unjustified from an ethical perspective. In this article, we argue that limited aggregation accounts represent a promising means for resolving interspecies conflicts. The reason for this is that they can appropriately consider the qualitative relevance of interests, their relative importance to each other, and the number of individuals affected. For our argument, we start from the premise that animals count morally for their own sake, albeit to a lesser extent than humans. That is, we accept the view that animals may be used, for example, as a source of food or in animal research. However, as we will show, many basic interests of animals are sufficiently similar to human interests and can thus be compared to them. Hence, they ought to be aggregated in cases of conflict with human interests. We illustrate our account and its practical implications with the real-world example of a human-animal conflict during the outbreak of a zoonotic disease among farmed animals. We conclude that, in many cases, animal interests ought to be given more importance than they currently receive, which includes distributing the burdens and risks of farming practices more fairly.

Interpersonal aggregation involves the combining and weighing of benefits and losses to multiple individuals in the course of determining what ought to be done. Most consequentialists embrace thoroughgoing interpersonal aggregation, the view that any large benefit to each of a few people can be morally outweighed by allocating any smaller benefit to each of many others, so long as this second group is sufficiently large. This would permit letting one person die in order to cure some number of (...) mild headaches instead. Most non-consequentialists reject thoroughgoing interpersonal aggregation despite also believing it is permissible to let one person die in order to prevent many cases of paraplegia instead. Non-consequentialists defend this asymmetry largely on the basis of intuition, and some rely on the notion of relevance to formalize the grounding intuitions. This article seeks to clarify and strengthen the non-consequentialist notion of relevance by engaging with three objections to it. (shrink)

Aggregative consequentialism and several other popular moral theories are threatened with paralysis: when coupled with some plausible assumptions, they seem to imply that it is always ethically indifferent what you do. Modern cosmology teaches that the world might well contain an infinite number of happy and sad people and other candidate value‐bearing locations. Aggregative ethics implies that such a world contains an infinite amount of positive value and an infinite amount of negative value. You can affect only a finite (...) amount of good or bad. In standard cardinal arithmetic, an infinite quantity is unchanged by the addition or subtraction of any finite quantity. So it appears you cannot change the value of the world. Modifications of aggregationism aimed at resolving the paralysis are only partially effective and cause severe side effects, including problems of “fanaticism”, “distortion”, and erosion of the intuitions that originally motivated the theory. Is the infinitarian challenge fatal? (shrink)

I argue that T.M. Scanlon's contractualist account of morality has difficulty accommodating our intuitions about the moral relevance of the number of people affected by an action. I first consider the "Complaint Model" of reasonable rejection, which restricts the grounds for an individual's rejection of a principle to its effects upon herself. I argue that it can accommodate our intuitions about numbers only if we assume that, whenever we do not know who will be affected, each individual may appeal (...) only to the _expected effects on her. This assumption, I suggest, leads to counterintuitive results in cases where, although we do not know who will be affected, we do know that _someone will be. I then consider two proposals to supplement the complaint model with a direct appeal to aggregation. I argue that both are open to serious objections. (shrink)

One of the major arguments against Act consequentialism is that it has counterintuitive implications in many kinds of cases. One of the methods of avoiding these counterintuitive verdicts is through the use of a “Generalization Argument” such as that proposed by Marcus Singer in his (1961) book Generalization in Ethics, which is intended to be an improved version of the traditional “What if everyone did that?” approach to moral theory. This Generalization Argument, however, also has counterintuitive implications due to (...) over-generalizing. In the spirit of his nomenclature, I thus propose that a form of consequentialism that partially generalizes, in a sense explained below, can avoid some of these counterintuitive results. The purpose of my proposing this new theory is to explore the idea of using some filter to sort actions into the categories of permissible vs. impermissible, and then use a consequentialist maximizing framework to choose between only the permissible options.

Paradoxical results concerning judgment aggregation have recently been invoked to defend the thesis that a corporate agent can be morally responsible for a decision without any of its individual members bearing such responsibility. I contend that the arguments offered for this irreducibility thesis are inconclusive. They do not pay enough attention to how we evaluate individual moral responsibility, in particular not to the role that a flawed assessment of the normative reasons that bear on the issue to be (...) decided on play in this context. I go on to propose a method for distributing corporate responsibility to individual members within the judgment aggregation framework. (shrink)

Desire', 'preference', 'utility', '(utility-aggregating) moral desirability' are terms that build on each other in this order. The article follows this definitional structure and presents these terms and their justifications. The aim is to present welfare-ethical criteria of the common good that define 'moral desirability' as an aggregation, e.g. addition, of individual utility: utilitarianism, utility egalitarianism, leximin, prioritarianism.

One of the currently popular dogmata of anti-consequentialism is that consequentialism doesn't respect, recognize, or in some important way account for what is referred to as the The charge is often made, but rarely explained in any detail, much less argued for. In this paper I explain what I take to be the most plausible interpretation of the separateness of persons charge. I argue that the charge itself can be deconstructed into at least two further objections to consequentialist theories. These (...) objections amount to (i) the rejection of axiological aggregation, and (ii) the rejection of deontic aggregation. Of these two objections, I argue that the first one, though often made, is untenable. I also argue that the second objection, in its various forms, relies on distinctions whose moral significance is vigorously denied by almost all consequentialist theorists. I thus argue that the separateness of persons objection poses no special threat to consequentialism. (shrink)

Department of Political Studies, Queen's University, 99 University Avenue, Kingston, Ontario, Canada, K7L 3N6. Email: farrelly{at}queensu.ca ' + u + '@' + d + ' '//--> Abstract Should we invest more public funding in basic aging research that could lead to medical interventions that permit us to safely and effectively retard human aging? In this paper I make the case for answering in the affirmative. I examine, and critique, what I call the Fairness Objection to making aging research a greater (...) priority than it currently is. The Fairness Objection presumes that support for aging research is limited to a simplistic utilitarian justification. That is, a mode of justification that is aggregative and permits imposing high costs on a few so that small benefits could be enjoyed by numerous recipients. I develop two arguments to refute the Fairness Objection. The Fairness Objection mischaracterizes the utilitarian argument for retarding human aging. It does so by invoking the fallacious conceptual distinction between "saving lives" and "extending lives", as well as making a number of mistaken assumptions concerning the likely benefits of retarding human aging. Secondly, I argue that the case for tackling aging can be made on contractualist , in addition to utilitarian, grounds. Because the harms of senescence are "morally relevant" to the harms of disease, contractualists can permit aggregation within lives. And thus no one could reasonably reject, I contend, a principle that makes the aspiration to tackle human aging more of a priority than it currently is. CiteULike Connotea Del.icio.us What's this?

ABSTRACT The philosophical tradition approaches to morals have their grounds predominantly on metaphysical and theological concepts and theories. Among the traditional ethics concepts, the most prominent is the Divine Command Theory (DCT). As per the DCT, God gives moral foundations to the humankind by its creation and through Revelation. Morality and Divinity are inseparable since the most remote civilization. These concepts submerge in a theological framework and are largely accepted by most followers of the three Abrahamic traditions: Judaism, Christianity, (...) and Islam: the greatest part of the human population. Holding faith and Revelation for its grounds, the Divine Command Theories are not strictly subject to the demonstration. The opponents to the Divine Command conception of morals, grounded in the impossibility of demonstration of its metaphysical and religious assumptions, have tried for many centuries (albeit unsuccessfully) to devalue its importance. They held the argument that it does not show material evidence and logical coherence and, for this reason, cannot be taken into account for scientific nor philosophical purposes. It is just a belief and, as so, should be understood. Besides these extreme oppositions, many other concepts contravene the Divine Command theories, in one or another way, in part or in full. Many philosophers and social scientists, from the classic Greek philosophy up to the present date, for instance, sustain that morality is only a construct, and thus culturally relative and culturally determined. However, this brings many other discussions and imposes the challenge to determine what is the meaning of culture, which elements of culture are morally determinant, and finally, what are the boundaries of such relativity. Moral determinists claim that everything related to human behavior, including morality, is determined, once free will does not exist. More recently, modern thinkers argued that there is a strict science of morality. However, the scientific method alone, despite explaining several facts and evidence, cannot enlighten the entire content and full meaning of ethics. Morals’ understanding requires a broader perception, and an agreement among philosophers, which they have never achieved. All of these questions have many different configurations depending on each philosophical strand, and start complex analysis and endless debates, as long as many of them are reciprocally conflictive. The universe and the atmosphere involving this thesis are the dominions of all these conceptual conflicts, observed from an objective and evolutionary standpoint. Irrespective of this circumstance and its intrinsic importance, however, these questions are far distant from the methodological approach of an analytical discussion on objective morals, what is, indeed, the aim and scope of this work. We should briefly revisit these prominent traditional theories because this thesis shelters a comparative study, and its assumptions at least differ profoundly from all traditional theories. Therefore, it becomes necessary offering direct and specific elements of comparison to the reader, for the right criticism, dispensing interruptive researches. However, even revisiting the traditional theories, for this comparative and critical exposure purpose, they will be kept by the side of our main concerns, as “aliena materia.” Irrespective of the validity of any or all of the elements of this discussion, and their meaning as the philosophical universe of this thesis, the purpose of this work is demonstrating and justifying the existence and meaning of prehistoric moral archetypes arisen directly from the very first social needs and efforts for survival. These archetypes are the definition of the essential foundation of ethics, its aggregation to the collective unconscious and corresponding logic organization and transmission to evolutionary stages of the human genome and different relations space-time, irrespective of any contemporary experience of the individuals. The system defined by these archetypes composes an evolutionary human social model. Is this a metaethical position? Yes, it is. Moreover, as in any metaethical reasoning, we should look carefully for the best and coherent routes, as the Analytical Philosophy offers them. Thus, this work should reasonably demonstrate that morals are not a cultural product of the civilized men or modern societies and that despite being subject to several cultural relative aggregations and subtractions, its essential foundations are archetypal and have never structurally changed. This reasoning induces that morality is an original attribute of the “homo sapiens”; it is not a property and nor an accident: it integrates the human essence and belongs to the realm of the ontological human identity. The human phenomena is a continuing process, playing its role between random determination and free will, and we need to question how morality began and how did it come to us in the present.

This paper examines the efforts of contractualists to develop an alternative to aggregation to govern our duty not to harm (duty to rescue) others. I conclude that many of the moral principles articulated in the literature seem to reduce to aggregation by a different name. Those that do not are viable only as long as they are limited to a handful of oddball cases at the margins of social life. If extended to run-of-the-mill conduct that accounts for (...) virtually all unintended (in the sense of undesired) harm to others—noncriminal activities that impose some risk of harm on others—they would rule out all action. Moreover, because such conduct poses an irreducible conflict between freedom of action and freedom from expected harm, it can be regulated only by principles that accept the necessity of making precisely the sorts of interpersonal trade-offs that contractualism is foundationally committed to reject: trade-offs in which the numbers count, such that a risk of serious harm to one person can be justified by small benefits to the many.

The use of aggregated quality of life estimatesin the formation of public policy and practiceguidelines raises concerns about the moralrelevance of variability in values inpreferences for health care. This variabilitymay reflect unique and deeply held beliefs thatmay be lost when averaged with the preferencesof other individuals. Feminist moral theorieswhich argue for attention to context andparticularity underline the importance ofascertaining the extent to which differences inpreferences for health states revealinformation which is morally relevant toclinicians and policymakers. To facilitatethese considerations, we (...) present an empiricalstudy of preferences for the timing andoccurrence of health states associated withhormone replacement therapy (HRT). Sixteenwomen between the ages of 45 and 55 wereenrolled in this pilot study. Theirpreferences regarding five health statesassociated with HRT (menopausal symptoms, sideeffects of HRT, breast cancer, myocardialinfarction, and osteoporosis) were assessed inquantitative terms known as utilities. Twostandard methods, the visual analog scale (VAS) and the standard gamble (SG), were used toassess utility and time preference (calculatedas a discount rate). The wide variability ofresponses underlines the importance oftailoring health care to individual women'spreferences. Policy guidelines whichincorporate utility analysis must recognize thenormative limitations of aggregatedpreferences, and the moral relevance ofindividual conceptions of health. (shrink)

Many moral theories are committed to the idea that some kinds of moral considerations should be respected, whatever the cost to ‘lesser’ types of considerations. A person's life, for instance, should not be sacrificed for the trivial pleasures of others, no matter how many would benefit. However, according to the decision-theoretic critique of lexical priority theories, accepting lexical priorities inevitably leads us to make unacceptable decisions in risky situations. It seems that to operate in a risky world, we (...) must reject lexical priorities altogether. This paper argues that lexical priority theories can, in fact, offer satisfactory guidance in risky situations. It does so by equipping lexical priority theories with overlooked resources from decision theory. (shrink)

Aggregation shows that virtue-relevant behavior is indeed highly predictable, and that individual differences in global virtues do indeed exist. Aggregation is a key response to the situationist argument against the existence of broad virtues. However, a concern with aggregation is that, because it is an average, the specifics of what are included in that average matter. In particular, if heinous actions could be included in the average, then aggregates cannot provide enough confidence that the holders of high (...) aggregates have not conducted heinous actions and thus cannot provide enough confidence that such people qualify as virtuous. Doris has challenged aggregation with this concern, and no one has responded substantively to this challenge. If Doris’ challenge is in fact correct, then the situationist argument against the existence of broad virtues stands. In the article, we present a full response to this concern. We argue that aggregation does not in fact allow heinous exceptions, because aggregates do indeed predict extreme single behaviors very well. In fact, aggregates do allow confidence that holders of high aggregates do not commit heinous actions. Thus, Doris’ rejection of the aggregation solution does not defeat aggregation, aggregation continues to stand in the defense of global virtues, and the situationist argument does not threaten the existence and predictive power of global virtues. Models of traits that rely on aggregates, such as Whole Trait Theory, may provide useful post-situationist models of virtues. (shrink)

Sometimes we ought to aggregate lesser harms to many such that they outweigh greater harms to a few, and sometimes we ought not to. This seems self-evident, but it has proven surprisingly difficult to construct a coherent moral theory out of this basic observation. In particular, it is difficult to explain (in a principled way) when we ought to aggregate. Relevance views attempt to solve this problem by arguing that sufficiently lesser harms are irrelevant to greater harms and thus (...) should not be taken into consideration. My thesis develops and defends a new relevance view. The first half of the thesis focuses on when lesser harms can aggregate and outweigh stronger harms. I start by solving a ‘fatal’ dilemma for all relevance views. I show that one horn of the dilemma is fatal but avoidable, whilst the other is unavoidable but not fatal, and that the dilemma rests on a faulty assumption of weak-additivity. I then develop a new relevance view based around the principle that we ought to balance harms by similarity (i.e., we ought to balance greater harms against similarly great harms and lesser harms against other lesser harms) before deciding whether lesser harms are relevant to greater harms. The second half focuses on when lesser harms can aggregate and tiebreak between stronger harms. First, I show that relevance views cannot capture our intuition that sufficiently lesser harms should not tiebreak between greater harms, without forfeiting our intuitions in other important cases. Secondly, I demonstrate that relevance views are sometimes inappropriately insensitive to the number of harms in tiebreaking cases. To solve these problems, I distinguish between two types of relevance, and I introduce Broomean fairness into my account. Doing so allows my view to capture all our intuitions about when lesser harms can tiebreak between stronger harms. (shrink)

Utilitarianism and other aggregationist moral theories view the public interest or the general welfare as an aggregate of individual goods. But critics of these theories question whether there is adequate justification for employing the concept of an aggregate social good. How are we supposed to sum up individual interests? Is it even possible to compare the utilities of different people or to assign values to individual utilities that can be added or subtracted? If not, how is the general good (...) to be aggregated? Critics have also raised concerns about the aggregative approach in ethics - concerns about its implications for distributive justice, individual liberty and democratic institutions. The essays in this volume explore these issues and address related questions. Some of them examine specific objections to aggregation, others analyze the very idea of a social good or social welfare. Other essays discuss the application of aggregative principles to particular problems. (shrink)

We are constantly making choices about how to invest our time and resources. From a moral perspective, we must ask which moral concerns are most deserving of our attention. Longtermism, as e.g. defined by Greaves and MacAskill, holds that our moral focus should be on the long-term future, and that current and medium-term moral problems are comparatively insignificant. This theory is centrally based on the assumption that the moral importance of individuals can be aggregated. Since (...) the number of individuals of future generations far exceeds the number of current individuals and those closer in time, future generations are to bemorally prioritised, according to longtermism. This paper explores the implications of rejecting the premise of moral aggregation of individuals and adopting a strongly non-aggregationist position instead. It is argued that, according to strong non-aggregationism, the magnitude of the probability with which our intervention actually make a difference, as well as whether we look at the available interventions from an ex ante or ex post perspective, are relevant factors in their moral assessment. Ultimately, the conclusion is reached that strong non-aggregationism does likely not support strongly longtermist conclusions. (shrink)

Non-Consequentialist moral theories posit the existence of moral constraints: prohibitions on performing particular kinds of wrongful acts, regardless of the good those acts could produce. Many believe that such theories cannot give satisfactory verdicts about what we morally ought to do when there is some probability that we will violate a moral constraint. In this article, I defend Non-Consequentialist theories from this critique. Using a general choice-theoretic framework, I identify various types of Non-Consequentialism that have otherwise been (...) conflated in the debate. I then prove a number of formal possibility and impossibility results establishing which types of Non-Consequentialism can -- and which cannot -- give us adequate guidance through through a risky world.

This essay explores the reasons for thinking that Scanlon's contractualist principle serves merely as a ?spare wheel?, an element that spins along nicely but bears no real weight, because it presupposes too much of what it should be explaning. The ambitions and scope of Scanlon's contractualism are discussed, as is Scanlon's thesis that contracualism will assess candidate moral principles individually rather than as sets. The final third of the paper critizes Scanlon's account of fairness and his approach to cases (...) where agents can save either one person or many people. (shrink)

The literature on collective action largely ignores the constraints that moral principle places on action-prompting intentions. Here I suggest that neither individualism nor holism can account for the generality of intentional contents demanded by universalizability principles, respect for persons, or proactive altruism. Utilitarian and communitarian ethics are criticized for nominalism with respect to social intentions. The failure of individualism and holism as grounds for moral theory is confirmed by comparing Tuomela's reductivist analysis of we-intentions with Gilbert's analysis of (...) social facts. Tuomela's account founders over intentions to cooperate, and Gilbert's cannot accommodate legitimate authority, vicarious agency, or group structure. (shrink)

This paper starts by addressing some objections to the very idea of aggregate social good. The paper goes on to review the case for letting aggregate social good be not only morally relevant but also sometimes morally decisive. Then the paper surveys objections to letting aggregate social good determine personal or political decisions. The paper goes on to argue against the idea that aggregate good is sensitive to desert and the idea that aggregate good should be construed as incorporating agent-relativity.
