Utilitarianism, Misc

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)

Suppose we want to do the most good we can with a particular sum of money, but we cannot be certain of the consequences of different ways of making use of it. This article explores how our attitudes towards risk and ambiguity bear on what we should do. It shows that risk-avoidance and ambiguity-aversion can each provide good reason to divide our money between various charitable organizations rather than to give it all to the most promising one. It also shows (...) how different attitudes towards risk and ambiguity affect whether we should give to an organization which does a small amount of good for certain or to one which does a large amount of good with some small or unknown probability.

The actualism/possibilism debate in ethics is traditionally formulated in terms of whether true counterfactuals of freedom about the future (true subjunctive conditionals concerning what someone would freely do in the future if they were in certain circumstances) even partly determine an agent's present moral obligations. But the very assumption that there are true counterfactuals of freedom about the future conflicts with the idea that freedom requires a metaphysically open future. We develop probabilism as a solution to the actualism/possibilism debate, a (...) solution that accommodates an open future requirement for freedom. We argue that probabilism resolves the conflicting intuitions that arise between actualists and possibilists and maintains certain distinct advantages over actualism and possibilism. (shrink)

In his 1972 paper “A Short Refutation Ethical Egoism,” Richmond Campbell purports to refute ethical egoism via a simple reductio. Although his argument has received critical attention, it has not been satisfactorily answered. In this paper I answer it, for reasons that go well beyond my immediate topic. Campbell’s argument calls for an answer partly because, as I show, if it succeeds against ethical egoism, then variations of it refute many other normative ethical theories, such as act utilitarianism.

A number of philosophers from Hobbes to Mill to Parfit have held some combination of the following views about the Golden Rule: (a) It is the cornerstone of morality across many if not all cultures. (b) It affirms the value of moral impartiality, and potentially the core idea of utilitarianism. (c) It is immune from evolutionary debunking, that is, there is no good naturalistic explanation for widespread acceptance of the Golden Rule, ergo the best explanation for its appearance in different (...) traditions is that people have perceived the same non-natural moral truth. De Lazari-Radek and Singer employ all three of these claims in an argument meant to vindicate Sidgwick's ‘principle of universal benevolence’. I argue that the Golden Rule is the cornerstone of morality only in Christianity, it does not advocate moral impartiality, and there is a naturalistic explanation for why versions of the Golden Rule appear in different traditions.

In this article I hold that utilitarians are wrong to want to disaggregate climate- induced harm, whether in terms of chaotic or linear causality. This is not because individual emissions do not count, in probabilistic terms, for risk projections of overall climate dam- age, rather because individual emissions only contribute to increasing atmospheric CO2 concentration if the anthropogenic flow of CO2 exceeds the amount of CO2 that can be naturally taken up by the biosphere, over a given time segment. I (...) therefore maintain that individual climate duties consist of reforming the social and technological structures that make each individual emission part of a collective phenomenon, global warming, which leads to an enormous global disutility, climate change. In the final part of the article, I ar- gue that utilitarian ethics would have much more to say if, instead of focusing on the dis- aggregation of climate-induced harm, it addressed the key issues of the energy transition, i.e. carbon pricing, research and development in green technologies and climate finance.

‘Simulation Hypotheses’ are imaginative scenarios that are typically employed in philosophy to speculate on how likely it is that we are currently living within a simulated universe as well as on our possibility for ever discerning whether we do in fact inhabit one. These philosophical questions in particular overshadowed other aspects and potential uses of simulation hypotheses, some of which are foregrounded in this article. More specifically, “A Theodicy for Artificial Universes” focuses on the moral implications of simulation hypotheses with (...) the objective of speculatively answering questions concerning computer simulations such as: If we are indeed living in a computer simulation, what might be its purpose? What aspirations and values could be inferentially attributed to its alleged creators? And would living in a simulated universe affect the value and meaning we attribute to our existence? (shrink)

Affective forecasting refers to the ability to predict future emotions, a skill that is essential to making decisions on a daily basis. Studies of the concept have determined that individuals are often inaccurate in making such affective forecasts. However, the mechanisms of these errors are not yet clear. In order to better understand why affective forecasting errors occur, this article seeks to trace the theoretical roots of this theory with a focus on its multidisciplinary history. The roots of affective forecasting (...) lie mainly in economics, with early claims positing that utility played a role in decision-making. Furthermore, the philosopher Jeremy Bentham’s descriptions of utilitarianism played a major role in our understanding of whether to define utility as a hedonic quality. The birth of behavioural economics resulted in a paradigm shift, introducing the concept of cognitive biases as influences on the accuracy of predicted utility. Daniel Gilbert and Timothy Wilson, the earliest researchers of affective forecasting errors, have proceeded with the concept of the accuracy of predicted affective utility to conduct experiments that seek to determine why our predictions of future affect are inaccurate and how such errors play a role in our decision-making.

It is not yet clear which response behavior requires self-regulatory effort in the moral dilemma task. Previous research has proposed that utilitarian responses require cognitive control, but subsequent studies have found inconsistencies with the empirical predictions of that hypothesis. In this paper we treat participants’ sensitivity to utilitarian gradients as a measure of performance. We confronted participants (N = 82) with a set of five dilemmas evoking a gradient of mean utilitarian responses in a 4-point scale and collected data on (...) heart rate variability and on utilitarian responses. We found positive correlations between tonic and phasic HRV and sensitivity to the utilitarian gradient in the high tonic group, but not in the low tonic group. Moreover, the low tonic group misplaced a scenario with a selfish incentive at the high end of the gradient. Results suggest that performance is represented by sensitivity correlated with HRV and accompanied with a reasonable placement of individual scenarios within the gradient. (shrink)

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.

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)

The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in (...) important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue-ethical view as such.

The moral error theory has become increasingly popular in recent decades. So much so indeed that a new issue emerged, the so-called “now-what problem”: if all our moral beliefs are false, then what should we do with them? So far, philosophers who are interested in this problem have focused their attention on the mode of the attitudes we should have with respect to moral propositions. Some have argued that we should keep holding proper moral beliefs; others that we should replace (...) our moral beliefs with fictional attitudes, beliefs in natural facts, or conative attitudes. But all these philosophers have set aside an important question about the content of these attitudes: which moral propositions, and more generally which moral theory, should we accept? The present paper addresses this neglected issue, arguing that moral error theorists should adopt a utilitarian moral fiction. In other words, they should accept the set of moral principles whose general acceptance would maximize overall well-being. (shrink)

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 :31–58, 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)

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)

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)

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.

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.

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)

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)

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.

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.

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)

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)

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.

An opinionated encyclopedia entry on Hastings Rashdall, in which several worries about his case for ideal utilitarianism are raised.

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 callrobustobligations, 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.

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.

John Broome has made major contributions to, and radical innovations in, contemporary moral philosophy. His research combines the formal method of economics with the philosophical analysis. Broome's works stretch over formal axiology, decision theory, philosophy of economics, population axiology, the value of life, the ethics of climate change, the nature of rationality, and practical and theoretical reasoning. Weighing and Reasoning brings together fifteen original essays from leading philosophers who have been influenced by the work and thought of John Broome.They explore (...) Broome's works on the theory of value, and his works on practical and theoretical reasoning. This volume also includes Broome's note on his intellectual history to date. (shrink)

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)

This is a critical review of David Phillips's Sidgwickian Ethics. The book deserves high praise.

Morality is demanding; this is a platitude. It is thus no surprise when we find that moral theories too, when we look into what they require, turn out to be demanding. However, there is at least one moral theory – consequentialism – that is said to be beset by this demandingness problem. This calls for an explanation: Why only consequentialism? This then leads to related questions: What is the demandingness problematic about? What exactly does it claim? Finally, there is the (...) question of what we do if we accept that there is a demandingness problem for consequentialism: How can consequentialists respond? The present chapter sets out to answer these questions (or at least point to how they could be answered). (shrink)

The pleasure principle (PP) may be a verifiable fundamental law of the living matter in the universe, and this law might then be used for forecasting human self-evolution. I do not pretend to “prove” PP, but argue that it must be regarded as a scientific hypothesis. Accordingly, I formulate verifiable and falsifiable postulates of PP. Their confirmation would allow the construction of a new scientific discipline, hedodynamics, that would be able to forecast the future development of human civilization and even (...) the probable structure and psychology of other rational beings within the universe. I suggest basic hedodynamical scenarios for human (posthuman) civilization and argue that the discovery of the neural correlate of pleasure would provide more detailed forecasts. In particular, I demonstrate how the studies of pleasure mechanisms might predict the degree of aggression in future societies. I conclude that PP may become a scientific basis for fundamental, not phenomenological (based on extrapolations), future forecasting on large timescales. (shrink)

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.

Utilitarianism, the approach to ethics based on the maximization of overall well-being, continues to have great traction in moral philosophy and political thought. This Companion offers a systematic exploration of its history, themes, and applications. First, it traces the origins and development of utilitarianism via the work of Jeremy Bentham, John Stuart Mill, Henry Sidgwick, and others. The volume then explores issues in the formulation of utilitarianism, including act versus rule utilitarianism, actual versus expected consequences, and objective versus subjective theories (...) of well-being. Next, utilitarianism is positioned in relation to Kantianism and virtue ethics, and the possibility of conflict between utilitarianism and fairness is considered. Finally, the volume explores the modern relevance of utilitarianism by considering its practical implications for contemporary controversies such as military conflict and global warming. The volume will be an important resource for all those studying moral philosophy, political philosophy, political theory, and history of ideas. (shrink)

A short encyclopedia article on Peter Singer which discusses his views on the obligations that the global wealthy have to the global poor and on our obligations to non-human animals.

The aim of this paper is to clarify the relationship of three thinkers, Hume, Bentham, and Mill in the context of utilitarianism. Through discussion, we shall figure out how and why utilitarianism is trustworthy.

Emissions grandfathering maintains that prior emissions increase future emission entitlements. The view forms a large part of actual emission control frameworks, but is routinely dismissed by political theorists and applied philosophers as evidently unjust. A sympathetic theoretical reconsideration of grandfathering suggests that the most plausible version is moderate, allowing that other considerations should influence emission entitlements, and be justified on instrumental grounds. The most promising instrumental justification defends moderate grandfathering on the basis that one extra unit of emission entitlements from (...) a baseline of zero emissions increases welfare to a greater extent where it is assigned to a high emitter than where it is assigned to a low emitter. Moderate grandfathering can be combined with basic needs and ability to pay considerations to provide an attractive approach to allocating emission entitlements. (shrink)

Parfit advertised the priority view as a new and fundamental theory in the ethics of distribution. He never discusses risk, and many writers follow suit when discussing the priority view. This article formalizes two popular arguments for a commonly accepted risk-free definition of the priority view. One is based on a direct attempt to define the priority view, the other is based on a contrast with utilitarianism and egalitarianism. But neither argument succeeds, and more generally, it is not possible to (...) make sense of the priority view in a risk-free framework. The article pays particular attention to the proper role of evaluative measurements in theorizing about the ethics of distribution. Despite appearances, approaching the priority view in terms of risk from the outset is argued to be quite natural. (shrink)

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.

David Phillips’s Sidgwickian Ethics is a penetrating contribution to the scholarly and philosophical understanding of Henry Sidgwick’s The Methods of Ethics. This note focuses on Phillips’s understanding of (aspects of) Sidgwick’s argument for utilitarianism and the moral epistemology to which he subscribes. In § I, I briefly outline the basic features of the argument that Sidgwick provides for utilitarianism, noting some disagreements with Phillips along the way. In § II, I raise some objections to Phillips’s account of the epistemology underlying (...) the argument. In § III, I reply to the claim that there is a puzzle at the heart of Sidgwick’s epistemology. In § IV, I respond to Phillips’s claim that Sidgwick is unfair in his argument against the (deontological) morality of common sense. (shrink)
