Utilitarianism, Misc

I discuss the interpretation of the principle of utility as a factual statement, the relevance of Halévy's interetation of Bentham, and then Bentham's relationship with James Mill and David Ricardo.

We give two social aggregation theorems under conditions of risk, one for constant population cases, the other an extension to variable populations. Intra and interpersonal welfare comparisons are encoded in a single ‘individual preorder’. The theorems give axioms that uniquely determine a social preorder in terms of this individual preorder. The social preorders described by these theorems have features that may be considered characteristic of Harsanyi-style utilitarianism, such as indifference to ex ante and ex post equality. However, the theorems are (...) also consistent with the rejection of all of the expected utility axioms, completeness, continuity, and independence, at both the individual and social levels. In that sense, expected utility is inessential to Harsanyi-style utilitarianism. In fact, the variable population theorem imposes only a mild constraint on the individual preorder, while the constant population theorem imposes no constraint at all. We then derive further results under the assumption of our basic axioms. First, the individual preorder satisfies the main expected utility axiom of strong independence if and only if the social preorder has a vector-valued expected total utility representation, covering Harsanyi’s utilitarian theorem as a special case. Second, stronger utilitarian-friendly assumptions, like Pareto or strong separability, are essentially equivalent to strong independence. Third, if the individual preorder satisfies a ‘local expected utility’ condition popular in non-expected utility theory, then the social preorder has a ‘local expected total utility’ representation. Fourth, a wide range of non-expected utility theories nevertheless lead to social preorders of outcomes that have been seen as canonically egalitarian, such as rank-dependent social preorders. Although our aggregation theorems are stated under conditions of risk, they are valid in more general frameworks for representing uncertainty or ambiguity. (shrink)

Theories that use expected utility maximization to evaluate acts have difficulty handling cases with infinitely many utility contributions. In this paper I present and motivate a way of modifying such theories to deal with these cases, employing what I call “direct difference taking”. This proposal has a number of desirable features: it’s natural and well-motivated, it satisfies natural dominance intuitions, and it yields plausible prescriptions in a wide range of cases. I then compare my account to the most plausible alternative, (...) a proposal offered by Arntzenius (2014). I argue that while Arntzenius’s proposal has many attractive features, it runs into a number of problems which direct difference taking avoids. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

The veil of ignorance argument was used by John C. Harsanyi to defend Utilitarianism and by John Rawls to defend the absolute priority of the worst off. In a recent paper, Lara Buchak revives the veil of ignorance argument, and uses it to defend an intermediate position between Harsanyi's and Rawls' that she calls Relative Prioritarianism. None of these authors explore the implications of allowing that agent's behind the veil are averse to ambiguity. Allowing for aversion to ambiguity---which is both (...) the most commonly observed and a seemingly reasonable attitude to ambiguity---however supports a version of Egalitarianism, whose logical form is quite different from the theories defended by the aforementioned authors. Moreover, it turns out that the veil of ignorance argument neither supports standard Utilitarianism nor Prioritarianism unless we assume that rational people are insensitive to ambiguity. (shrink)

Effective altruists either believe they ought to be, or strive to be, doing the most good they can. Since they’re human, however, effective altruists are invariably fallible. In numerous situations, even the most committed EAs would fail to live up to the ideal they set for themselves. This fact raises a central question about how to understand effective altruism. How should one’s future prospective failures at doing the most good possible affect the current choices one makes as an effective altruist? (...) This question is important to answer not only because every effective altruist will face this question due to typical human akrasia, but also because how the question is answered will determine just how demanding effective altruism can be. I argue that no matter how effective altruists answer this question, they will have to take on some commitments seemingly antithetical to their movement. More precisely, I argue that effective altruism is subject to a dilemma. Effective altruists’, at times, implicit actualist assumptions (i) commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (ii) undermine effective altruists’ arguments against moral offsetting and giving to charities close to the heart. Yet, effective altruists’, at times, implicit possibilist assumptions (iii) also commit them to conclusions seemingly antithetical to what typical effective altruists actually believe, as well as the spirit of the movement and (iv) undermine typical responses to demandingness worries for the normative conception of effective altruism. I argue that the best way out of the dilemma is to accept hybridism, though even hybridism won’t preserve every commitment of effective altruism. (shrink)

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

Let us imagine an ideal ethical agent, i.e., an agent who (i) holds a certain ethical theory, (ii) has all factual knowledge needed for determining which action among those open to her is right and which is wrong, according to her theory, and who (iii) is ideally motivated to really do whatever her ethical theory demands her to do. If we grant that the notions of omniscience and ideal motivation both make sense, we may ask: Could there possibly be an (...) ideal utilitarian, that is, an ideal ethical agent whose ethical theory says that our only moral obligation consists in maximizing utility? I claim that an ideal agent cannot be utilitarian. My reasoning against ideal utilitarianism will parallel Putnam's famous argument against the brains in a vat. Putnam argues that an envatted brain cannot describe its own situation because its words do not refer to brains and vats; I argue that an ideal utilitarian cannot entertain or communicate the beliefs necessary to being a utilitarian.

Some people have supposed that utility is good in itself, non-in-strumentally good, as distinct from good because conducive to other good things. And in modern versions of this view, utility often means want-satisfaction, as distinct from pleasure or happiness. For your want that p to be satisfied, is it necessary that you know or believe that p, or sufficient merely that p is true? However that question is answered, there are problems with the view that want-satisfaction is a non-instrumental good. (...) What if you want something only because you have a false belief? What if the time at which you want that p is fifty or five hundred years before the time to which p itself refers? To meet these difficulties, qualifications have to be introduced, and much has been written about how exactly these qualifications are to be framed.1 There is however what may be a rather more serious objection to the view that want-satisfaction is a non-instrumental good, or rather to the combination of that view with the principle that it is sufficient for your want that p to be satisfied simply that p is true. The objection is that this combination forces you to give undue weight to the mere acquisition of desires when you come to make judgements about changes in the value of things. It forces you to say that for any true proposition p, which initially you do not want to be true, your mere acquisition of a desire that p will, other things being equal, make the world better. Non-instrumental value can be increased merely by multiplying desires, even though everything else remains the same. Surely, however, improving the world is not as easy as that. (shrink)

David Hume, Adam Smith, Jeremy Bentham and John Stuart Mill are often viewed as contributors to or participants in a common tradition of thought roughly characterized as ‘the liberal tradition’ or the tradition of ‘bourgeois ideology’. This view, however useful it may be for polemical or proselytizing purposes, is in some important respects historiographically unsound. This is not to deny the importance of asking what twentieth-century liberals or conservatives might find in the works of, say, David Hume to support their (...) respective ideological persuasions. It is only to insist that attempts to use selected arguments, or parts of arguments, from great eighteenth-century thinkers to shore up twentieth-century programmatic political positions must be categorically distinguished from attempts to understand what Hume, Smith, Bentham or Mill actually meant, or could imaginably have meant, to say.

Criticism of a moral theorizing that disparages common moral thought for violating presumed a priori principles. Argues for questioning alleged principles.

Katarzyna de Lazari-Radek and Peter Singer have recently provided an evolutionary argument for utilitarianism. They argue that most of our deontological beliefs were shaped by evolution, from which they conclude that these beliefs are unjustified. By contrast, they maintain that the utilitarian belief that everyone’s well-being matters equally is immune to such debunking arguments because it wasn’t similarly influenced. However, Guy Kahane remarks that this belief lacks substantial content unless it is paired with an account of well-being, and he adds (...) that utilitarian beliefs about wellbeing—e.g. the belief that pleasure is good and pain is bad—were probably shaped by evolution. Logically, de Lazari-Radek and Singer should therefore reject these beliefs along with the deontological beliefs that evolved. The present paper is a defense of their argument. After considering a number of unsuccessful replies to Kahane’s objection, I put forward a more promising solution: de Lazari-Radek and Singer should combine their objectivist view in metaethics with a subjectivist account of well-being, such as the desire theory. Such a hybrid account would tackle Kahane’s challenge because subjective accounts of value are immune from evolutionary debunking arguments. And it would be compatible with utilitarianism, which doesn’t fit very well with metaethical subjectivism. Before concluding, I deal with two concerns that this solution might raise: I argue that the desire theory is actually subjective enough to escape Kahane’s objection, and I deny that retreating to the combination of ethical objectivism and prudential subjectivism is ad hoc.

The paper discusses Ricardo's relationship to Mill and Bentham. It discusses first the origins of the myth of Ricardo's dependence from Bentham through Mill, and Halévy's contribution to the freezing of such a myth. The paper reconstructs what were their shared political commitments and activities and the kind of specific political views and agenda that may be ascribed to Ricardo himself. The paper discusses then the question of Ricardo's adhesion to Benthamite ethics. It examines fragments in Ricardo's correspondence with Maria (...) Edgeworth and Francis Place, and adds fresh light on the issue by highlighting the partial overlapping between Bentham's ethics and the kind of intuitionism with theological consequentialism that Ricardo had learned from the Unitarian minister Thomas Belsham.

Despite the strong criticisms to ethical utilitarianism, this theory has not succumbed and remains one of the most notorious. The main criticisms address to the consequentialist conception of right that underlies the theory. However,it has been such a conception of right that, at the same time, saved utilitarianism. The article set out the features and changes that, according to the author, are the causes to explain the subsistence of utilitarianism.

Probability is a central concept in utilitarian moral theory, almost impossible to do without. I attempt to clarify the role of probability, so that we can be clear about what we are aiming for when we apply utilitarian theory to real cases. I point out the close relationship between utilitarianism and expected-utility theory, a normative standard for individual decision-making. I then argue that the distinction between “ambiguity” and risk is a matter of perception. We do not need this distinction in (...) the theory itself. In order to make this argument I rely on the personalist theory of probability, and I try to show that, within this theory, we do not need to give up completely on the idea that a “true probability” exists. Finally, I discuss several examples of applied utilitarianism, emphasizing the role of probability in each example: reasonable doubt, the precautionary principle in risk regulation, charity, climate change, and voting.

Biomedical sciences cannot answer the question who should be saved from death if not everyone can be. This is an ethical issue. However, we face exactly this question when deliberating on the criteria for organ allocation. The main aim of this article is to formulate a pluralistic theory of just distribution of organs, which incorporates the tenets of utilitarianism, egalitarianism and sufficientarianism. Each constituent theory adopts a different value as a criterion for organ allocation. For utilitarianism it is a health (...) benefit for the patient, for egalitarianism it is the ratio of deserts and health-related well being, for sufficientarianism what is important is that the candidate for a transplant be situated below the sufficientarian threshold. The article presents a proposal to reconcile these three competing theories. (shrink)

Élie HALÉVY (1870-1937), philosophe et historien des idées, fut professeur à l'École libre des sciences politiques, l'ancêtre de l'actuel Sciences Po. Comme son autre grand ouvrage, l'Histoire du peuple anglais au XIXe siècle, paru en six tomes de 1913 à 1932, les trois tomes de La formation du radicalisme philosophique, parus en 1901 pour les deux premiers et en 1904 pour le troisième, reflètent pour partie ses enseignements de l'Ecole libre consacrés à l'histoire britannique. Le premier tome, La jeunesse de (...) Bentham 1776-1789, étudie la doctrine utilitariste non seulement chez celui qu'on regarde comme son fondateur principal, Jeremy Bentham, mais aussi chez les nombreux auteurs qui, en Grande-Bretagne et sur le continent, en dessinèrent avant lui les contours. Le deuxième tome, L’évolution de la doctrine utilitaire de 1789 à 1815, montre comment l'utilitarisme revêtit la forme non seulement d'une école de pensée, mais aussi d'un mouvement pour la réforme économique, sociale et politique. Le rôle coordonnateur nouveau de James Mill, ainsi qu'une convergence de vues avec les économistes, qui poussaient dans le sens des réformes, marquèrent notamment cette évolution. Le troisième tome, Le radicalisme philosophique, continue d'étudier la transformation de l'école en mouvement après la fin des guerres napoléoniennes, lorsque celle-ci commence à engranger ses premiers grands succès réformistes. Bentham, James Mill et les autres penseurs utilitaires sont alors réunis sous l'appellation de philosophic radicals. Le terme temporel de l'ouvrage est le Reform Act de 1832, première étape vers la modernisation du système électoral, que la propagande de ce groupe ne contribua pas peu à faire aboutir. Quoique l'ouvrage d'Halévy vaille en premier lieu par l'immense savoir qu'il déploie, et le nombre et l'excellence des citations qu'il propose, il comporte aussi des thèses historiques et philosophiques originales. On peut citer parmi les premières la thèse, qui relie les trois tomes, voulant que l'utilitarisme britannique trouve sa forme achevée dans l'intervention sur la société, lorsqu'il se mue en radicalisme philosophique, et parmi les secondes, la thèse, énoncée au début du premier tome, voulant qu'il existe trois modèles dominants de jonction des intérêts individuels (la fusion sympathique, l'identification naturelle et l'identification artificielle). Une autre grande thèse, à la fois historique et philosophique, affirme en substance que l'économie politique classique serait un département spécialisé de la pensée utilitaire. La question de savoir jusqu'à quel point Smith, Ricardo et Malthus ont pu adhérer au "principe d'utilité" de Bentham est toujours débattue. En même temps que les élucidations apportées à ce principe, elle contribue à expliquer l'intérêt que les historiens de la pensée économique continuent de porter à l'ouvrage. L'auteur a participé à la réédition de La formation du radicalisme philosophique en 1995 par les Presses Universitaires de France (P.U.F.), suivant un projet collectif lancé par Monique Canto-Sperber. Dans le présent article, antérieur à cette réédition, l'auteur tentait de résumer brièvement un livre qui demeure irremplaçable en dépit d'une conception et d'un style quelque peu datés. (shrink)

This chapter of the Handbook of Utility Theory aims at covering the connections between utility theory and social ethics. The chapter first discusses the philosophical interpretations of utility functions, then explains how social choice theory uses them to represent interpersonal comparisons of welfare in either utilitarian or non-utilitarian representations of social preferences. The chapter also contains an extensive account of John Harsanyi's formal reconstruction of utilitarianism and its developments in the later literature, especially when society faces uncertainty rather than probabilistic (...) risk.

Henry Sidgwick taught G.E. Moore as an undergraduate at the University of Cambridge. Moore found Sidgwick’s personality less than attractive and his lectures “rather dull”. Still, philosophically speaking, Moore absorbed a great deal from Sidgwick. In the Preface to the Trinity College Prize Fellowship dissertation that he submitted in 1898, just two years after graduation, he wrote “For my ethical views it will be obvious how much I owe to Prof. Sidgwick.” Later, in Principia Ethica, Moore credited Sidgwick with having (...) “first clearly exposed the [naturalistic] fallacy” – a fallacy putatively committed when one defines naturalistically or super-naturalistically “good” – which was one of the book’s main ambitions (PE 39; also 17, 59). It is therefore unsurprising that Moore remarks in the intellectual autobiography he wrote years later that “From…[Sidgwick’s] published works…I have gained a good deal, and his clarity and his belief in Common Sense were very sympathetic to me.” This influence did not, however, prevent Moore from registering disagreements with Sidgwick, the sharpest of which concern the viability of egoism and the nature of the good. The disagreements between Sidgwick and Moore speak to many important moral theoretical issues arising both within and without the utilitarian tradition in ethical thinking. Because the two share much in common, a critical comparison of them on a range of moral philosophical questions proves instructive. It will tell us in particular something about the general direction of ethical thinking in the utilitarian tradition at the dawn of the twentieth century. This chapter has four parts. Part I compares the versions of utilitarianism to which Sidgwick and Moore subscribed. Part II examines the arguments each provides for the view. Part III discusses their conflicting theories of value. Part IV sums things up. (shrink)

My aim in this chapter is to push back against the tendency to emphasize Mill’s break from Bentham rather than his debt to him. Mill made important advances on Bentham’s views, but I believe there remains a shared core to their thinking—over and above their commitment to the principle of utility itself—that has been underappreciated. Essentially, I believe that the structure of Mill’s utilitarian thought owes a great debt to Bentham even if he filled in that structure with a richer (...) conception of human nature and developed it in more liberal directions. This commonality is revealed, in particular, in Mill’s own institutional designs and practical reform proposals in Considerations on Representative Government and related writings. If this is right, then the tendency of interpreters to highlight their differences rather than their similarities has been to the detriment of both Mill and Bentham scholarship, and so to our understanding of the rise of liberal utilitarianism.

This book provides an entry-level introduction to philosophical ethics, theories of moral reasoning, and selected issues in applied ethics. Chapter 1 describes the importance of philosophical approaches to ethical issues, the general dialectical form of moral reasoning, and the broad landscape of moral philosophy. Chapter 2 presents egoism and relativism as challenges to the presumed objectivity and unconditionality of morality. Chapters 3, 4 and 5 discuss utilitarianism, deontology, and virtue ethics, respectively. Each chapter begins with a general overview of the (...) characteristic theory of value and moral reasoning and proceeds to present a more refined account based on a prominent historical source (Mill, Kant, and Aristotle, respectively). It then discusses strengths and weaknesses of the theory from a contemporary perspective, including more recent developments, defenses, and critiques. Each chapter includes an appendix in which secondary, less prominent, or more complex issues are discussed. Chapters 6-9 address in detail a prominent area of applied ethics: 6. abortion, 7. assisted dying, 8. Biotechnology, 9. Animals and eating. Each of these chapters presents an introduction to the topic, including definitions, historical and contemporary developments and contexts, etc.; the various questions and issues involved; and an application of each theory from multiple points of view. Each chapter also includes a set of primary readings along with an extensive bibliography. Chapter 10 discusses four more areas of applied ethics: War, Torture, and Terrorism; Capital Punishment; Environmental Ethics; and Same-Sex Marriage. The treatment of these topics focuses mainly on the introductory material. While there is some discussion of the various ethical arguments, it is less comprehensive or detailed compared to other chapters. However, several primary resources are listed to supplement the discussion in the textbook. (shrink)

Pacifists and their opponents disagree not only about moral questions, but rather often about factual questions as well—as seen when looking at the controversy surrounding the crisis in Kosovo. According to my reconstruction of pacifism, this is not surprising since the pacifist,legitimately, looks at the facts in the light of her system of value. Her opponent, in turn, looks at the facts in the light of an alternative value system, and the quarrel between the two parties about supposedly descriptive matters (...) never ceases, as there is no objective reality about the war in question that could settle the issue.In my view, the pacifist's value-laden way of looking at reality implicitly obeys three epistemic imperatives. First, the Epistemic Imperative concerning Human Nature ("Resist demonizing the other side; always try to understand the case from the other point of view"). Second, the Epistemic Imperative concerning Non-Violent Alternatives ("Always search for non-violent alternatives to military action"). Third, the Epistemic Imperative concerning Uncontrolled Escalation ("Hone your senses to the uncontrolled, irreversible side effects of military action, particularly to the danger of military escalation leading to another world war"). Objective reality has no way of telling us how far we should go in following these imperatives. Rather, we have to make the decision about how far we are going to take them ourselves. In this way, the pacifist's epistemic imperatives are comparable to Kant's regulative principles. (shrink)

A leading classical utilitarian, John Stuart Mill is an unlikely contributor to the public reason tradition in political philosophy. To hold that social rules or political institutions are justified by their contribution to overall happiness is to deny that they are justified by their being the object of consensus or convergence among all those holding qualified moral or political viewpoints. In this chapter, I explore the surprising ways in which Mill nevertheless works to accommodate the problems and insights of the (...) public reason tradition, and the extent to which he makes arguments that can help those working within that tradition. Mill’s utilitarian theory incorporates the claim that the demands of social life require a publicly accepted set of normative expectations to govern judgments about when one has met one’s obligations and, relatedly, about the appropriateness of blame or punishment.

This edition of _Utilitarianism_ supplements the text of Mill’s classic essay with 58 related remarks carefully selected from Mill’s other writings, ranging from his treatise on logic to his personal correspondence. In these remarks, Mill comments on specific passages of _Utilitarianism_, elaborates on topics he handles briefly in _Utilitarianism_, and discusses additional aspects of his moral thought. Short introductory comments accompany the related remarks, and an editor’s introduction provides an overview of _Utilitarianism_ crafted specifically to enhance accessibility for first-time readers (...) of the essay.

In my dissertation, I analyze, interpret, and defend John Stuart Mill's proof of the principle of utility in the fourth chapter of his Utilitarianism. My purpose is not to glorify utilitarianism, in a full sweep, as the best normative ethical theory, or even to vindicate, on a more specific level, Mill's universalistic ethical hedonism as the best form of utilitarianism. I am concerned only with Mill's utilitarianism, and primarily with his proof of the principle of utility. My overarching purpose guiding (...) the entire work is to show that Mill proceeds intelligibly and systematically in pursuing a well-defined project in the fourth chapter of Utilitarianism, and that he successfully defends what he sets out to establish in his proof of the principle of utility. To this end, I devote the bulk of my efforts to studying and responding to traditionally popular and persistently enduring objections to the proof that are handed down from one generation to the next in the philosophical community as a standard companion to Utilitarianism. The primary objections to which I respond at length are the charges that Mill commits the naturalistic fallacy, the fallacy of equivocation, and the fallacy of composition in his proof. Secondary literature on the subject consists of journal articles and book chapters that treat one or another but not all of these problems. My research has convinced me that, although these commentaries are generally quite good, they are mutually incompatible, and they are neither severally nor jointly sufficient to produce the kind of comprehensive defense that would do justice to Mill's proof of the principle of utility. This kind of comprehensive defense is what I intend to contribute to secondary literature on the subject. Specifically, my ultimate contribution to secondary literature is an interpretation of Mill's proof of the principle of utility in its entirety, absolved of the three fallacies commonly attributed to the proof, yet faithful to the text at all points.

This is a defense of John Stuart Mill’s proof of the principle of utility in the fourth chapter of his Utilitarianism. The proof is notorious as a fallacious attempt by a prominent philosopher, who ought not to have made the elementary mistakes he is supposed to have made. This book shows that he did not. The aim is not to glorify utilitarianism, in a full sweep, as the best normative ethical theory, or even to vindicate, on a more specific level, (...) Mill’s universalistic ethical hedonism as the best form of utilitarianism. The book is concerned only with Mill’s utilitarianism, and primarily with his proof of the principle of utility. The purpose is to show that Mill proceeds intelligibly and systematically in pursuing a well-defined project in the fourth chapter of Utilitarianism, and that he successfully defends what he sets out to establish in his proof of the principle of utility.

Standard epistemology takes it for granted that there is a special kind of value: epistemic value. This claim does not seem to sit well with act utilitarianism, however, since it holds that only welfare is of real value. I first develop a particularly utilitarian sense of “epistemic value”, according to which it is closely analogous to the nature of financial value. I then demonstrate the promise this approach has for two current puzzles in the intersection of epistemology and value theory: (...) first, the problem of why knowledge is better than mere true belief, and second, the relation between epistemic justification and responsibility.

The introduction (about 6,000 words) to _The Cambridge Companion to Utilitarianism_, in three sections: utilitarianism’s place in recent and contemporary moral philosophy (including the opinions of critics such as Rawls and Scanlon), a brief history of the view (again, including the opinions of critics, such as Marx and Nietzsche), and an overview of the chapters of the book.

This is a critical review of Roger Crisp's The Cosmos of Duty. The review praises the book but, among other things, takes issue with some of Crisp's criticisms of Sidgwick's view that resolution of the free will problem is of limited significance to ethics and with Crisp's claim that in Methods III.xiii Sidgwick defends an axiom of prudence that undergirds rational egoism.

Central to the Rawls–Harsanyi dispute is the question of whether the core modeling device of Rawls' theory of justice, the original position, justifies Rawls' principles of justice, as Rawls suggests, or whether it justifies the average utility principle, as Harsanyi suggests. Many commentators agree with Harsanyi and consider this dispute to be primarily about the correct application of normative decision theory to Rawls' original position. I argue that, if adequately conceived, the Rawls–Harsanyi dispute is not primarily a dispute about the (...) correct application of normative decision theory to Rawls' original position. Instead, Rawls and Harsanyi aim to model different moral ideals, and this difference in their moral assumptions leads them to significantly different conclusions about justice. There is no winner in the Rawls–Harsanyi dispute. Instead, the dispute merely clarifies the moral ideals and their formal representations that need to be assumed in order to justify either Rawls' contractualist principles of justice or the average utility principle. Thus understood, the Rawls–Harsanyi dispute offers a promising starting point for future research that can deepen and enrich our understanding of the demands of justice. (shrink)

Various moral theories are essentially welfare-involving in that they appeal to the promotion or the respect of well-being in accounting for the moral rightness of at least some acts. Further, various theories of well-being are essentially morality-involving in that they construe well-being in a way that essentially involves morality in some form or other. It seems that, for any moral theory that is essentially welfare-involving and that relies on a theory of well-being that is essentially morality-involving, a circularity problem may (...) well arise, one where moral rightness will end up being accounted for partly in terms of well-being, which itself is already being accounted for partly in terms of moral rightness. In this paper I will elaborate on this last point. Then I will examine five responses to the circularity problem at issue, and I will argue that one of them appears to be at least slightly better than all of the others. (shrink)

We propose a generalization of expected utility that we call generalized EU (GEU), where a decision maker’s beliefs are represented by plausibility measures and the decision maker’s tastes are represented by general (i.e., not necessarily real-valued) utility functions. We show that every agent, “rational” or not, can be modeled as a GEU maximizer. We then show that we can customize GEU by selectively imposing just the constraints we want. In particular, we show how each of Savage’s postulates corresponds to constraints (...) on GEU. (shrink)

Available from UMI in association with The British Library. Requires signed TDF. ;The thesis consists in the development and application of an ideal utilitarian moral theory. ;In chapter one, classical Mental State and modern Desire theories of prudential value are rejected. In chapter two, perfectionism is rejected and an alternative ideal utilitarian Objective List theory is set out. In chapter three, it is argued that prudential rationality requires maximization and temporal neutrality. The aggregation and incommensurability of values is discussed. In (...) chapter four, it is argued that value alone gives rise to grounding reasons for action; the only values are prudential values; we are required to be personally as well as temporally neutral; moral rationality is maximizing. A problem arising when a certain form of incommensurability is combined with the notion of maximizing expected utility is examined. In chapter five, an intrapersonally indirect form of moral theory is defended. ;In the second, practical part of the thesis, the theory developed in the first part is applied to two moral problems: vegetarianism and future generations. In chapter six, the conclusion is that utilitarianism requires us to eat non-intensively-reared meat and to abstain from intensively reared meat. In chapter seven, population problems arising from Derek Parfit's work are considered in the light of the theory. (shrink)

This essay explores the moral reasoning underpinning the common view that it is worse to kill a human compared with killing an animal. After examining the serious deficiencies of traditional approaches, the author develops an alternative utilitarian-based framework that proportions the seriousness of killing to levels of sentience. He demonstrates how this new approach avoids the problems faced by the application of standard utilitarian formulae in weighing the seriousness of killing many low-sentience animals vis-á-vis killing a single human. The author (...) concludes with a discussion of how this new approach overcomes the difficulties faced by Peter Singer’s dualist form of utilitarianism. (shrink)

There is a common view that the utilitarian theory of John Stuart Mill is morally realist and involves a strong kind of practical obligation. This article argues for two negative theses and a positive thesis. The negative theses are that Mill is not a moral realist and that he does not believe in certain kinds of obligations, those involving external reasons and those I call robust obligations, obligations with a particular, strong kind of practical authority. The positive thesis is that (...) Mill’s metaethical position can be interpreted as a Humean constructivist view, a metaethical view that is constructivist about value and entails the existence of practical reasons, but not external reasons or robust obligations. I argue that a Humean constructivist reading of Mill’s theory is reasonable, and strengthens Mill’s argument from desire for the value of happiness, an important but notoriously weak aspect of his theory.

Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring the worst-off, maximising total benefits, and promoting and rewarding social usefulness. No single principle is sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points systems, quality-adjusted life-years, and (...) disability-adjusted life-years. We recommend an alternative system—the complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates prognosis, save the most lives, lottery, and instrumental value principles.

We introduce a ranking of multidimensional alternatives, including uncertain prospects as a particular case, when these objects can be given a matrix form. This ranking is separable in terms of rows and columns, and continuous and monotonic in the basic quantities. Owing to the theory of additive separability developed here, we derive very precise numerical representations over a large class of domains (i.e., typically notof the Cartesian product form). We apply these representationsto (1)streams of commodity baskets through time, (2)uncertain social (...) prospects, (3)uncertain individual prospects. Concerning(1), we propose a finite horizon variant of Koopmans’s (1960) axiomatization of infinite discounted utility sums. The main results concern(2). We push the classic comparison between the exanteand expostsocial welfare criteria one step further by avoiding any expected utility assumptions, and as a consequence obtain what appears to be the strongest existing form of Harsanyi’s (1955) Aggregation Theorem. Concerning(3), we derive a subjective probability for Anscombe and Aumann’s (1963) finite case by merely assuming that there are two epistemically independent sources of uncertainty. (shrink)
