John Stuart Mill's Utilitarianism is one of the most important, controversial, and suggestive works of moral philosophy ever written. Mill defends the view that all human action should produce the greatest happiness overall, and that happiness itself is to be understood as consisting in "higher" and "lower" pleasures. This volume uses the 1871 edition of the text, the last to be published in Mill's lifetime. The text is preceded by a comprehensive introduction assessing Mill's philosophy and the alternatives to (...) utilitarianism, and discussing some of the specific issues Mill raises in Utilitarianism.

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)

Utilitarianism is the view according to which the only basic requirement of morality is to maximize net aggregate welfare. This position has implications for the ethics of creating and rearing children. Most discussions of these implications focus either on the ethics of procreation and in particular on how many and whom it is right to create, or on whether utilitarianism permits the kind of partiality that child rearing requires. Despite its importance to creating and raising children, there are, (...) by contrast, few sustained discussions of the implications of utilitarian views of welfare for the matter of what makes a child’s life go well. This paper attempts to remedy this deficiency. It has four sections. Section one discusses the purpose of a theory of welfare and its adequacy conditions. Section two evaluates what prominent utilitarian theories of welfare imply about what makes a child’s life go well. Section three provides a sketch of a view about what is prudentially valuable for children. Section four sums things up. (shrink)

An overview (about 8,000 words) of act utilitarianism, covering the basic idea of the theory, historical examples, how it differs from rule utilitarianism and motive utilitarianism, supporting arguments, and standard objections. A closing section provides a brief introduction to indirect utilitarianism (i.e., a Hare- or Railton-style view distinguishing between a decision procedure and a criterion of rightness).

Ideal utilitarianism states that the only fundamental requirement of morality is to promote a plurality of intrinsic goods. This paper critically evaluates Hastings Rashdall’s arguments for ideal utilitarianism, while comparing them with G. E. Moore’s arguments. Section I outlines Rashdall’s ethical outlook. Section II considers two different arguments that he provides for its theory of rightness. Section III discusses his defence of a pluralist theory of value. Section IV argues that Rashdall makes a lasting contribution to the defence (...) of ideal utilitarianism. (shrink)

Utilitarianism has an apparent pedigree when it comes to animal welfare. It supports the view that animal welfare matters just as much as human welfare. And many utilitarians support and oppose various practices in line with more mainstream concern over animal welfare, such as that we should not kill animals for food or other uses, and that we ought not to torture animals for fun. This relationship has come under tension from many directions. The aim of this article is (...) to add further considerations in support of that tension. I suggest three ways in which utilitarianism comes significantly apart from mainstream concerns with animal welfare. First, utilitarianism opposes animal cruelty only when it offers an inefficient ratio of pleasure to pain; while this may be true of eating animal products, it is not obviously true of other abuses. Second, utilitarianism faces a familiar problem of the inefficacy of individual decisions; I consider a common response to this worry, and offer further concerns. Finally, the common utilitarian argument against animal cruelty ignores various pleasures that humans may get from the superior status that a structure supporting exploitation confers. (shrink)

The aim of this commentary is to critically examine Matti Häyry’s article ‘Just Better Utilitarianism’, where he argues that liberal utilitarianism can offer a basis for moral and political choices in bioethics and thus could be helpful in decision-making. This commentary, while generally sympathetic to Häyry’s perspective, argues that Häyry should expand on who belongs to our moral community because, to solve practical ethical issues, we need to determine who (and what) deserves our moral consideration. Challenging Häyry’s principle (...) of actual or prospective existence, this commentary suggests that – at least sometimes – the quality of life of those who will never come into existence matters. In a similar vein, this commentary aims to show that determining how to treat mindless humans such as fetuses might pose difficulties for liberal utilitarianism unless the issue of the boundaries of the moral community is addressed.

This chapter offers a concise discussion of classic utilitarianism which is the prototypical moral doctrine of the utilitarian family. It starts with an analysis of the classic utilitarian criterion of rightness, gives an overview over its virtues and vices, and suggests an overall assessment of its adequacy as a theory of morality. Furthermore, it briefly discusses whether classic utilitarianism holds promise as a philosophy for doing business.

Lara Buchak argues for a version of rank-weighted utilitarianism that assigns greater weight to the interests of the worse off. She argues that our distributive principles should be derived from the preferences of rational individuals behind a veil of ignorance, who ought to be risk averse. I argue that Buchak’s appeal to the veil of ignorance leads to a particular way of extending rank-weighted utilitarianism to the evaluation of uncertain prospects. This method recommends choices that violate the unanimous (...) preferences of rational individuals and choices that guarantee worse distributions. These results, I suggest, undermine Buchak’s argument for rank-weighted utilitarianism. (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.

It is sometimes said that permitting, say, voluntary euthanasia would erode the motivations and inhibitions supporting other, legitimate prohibitions on killing to the point where widespread disregard for the moral law would result. this paper discusses the relevance of such "slippery slope" arguments for the rule-utilitarian who claims that we can assess moral rules by asking whether their acceptance would maximize utility. first it is argued that any normative theory of this type cannot recognize slope arguments as legitimate considerations in (...) this assessment. second, it is suggested that a theory based on the very different notion of choosing a moral code can permit slope arguments to weigh as relevant considerations.

Scalar Utilitarianism eschews foundational notions of rightness and wrongness in favor of evaluative comparisons of outcomes. I defend Scalar Utilitarianism from two critiques, the first against an argument for the thesis that Utilitarianism's commitments are fundamentally evaluative, and the second that Scalar Utilitarianism does not issue demands or sufficiently guide action. These defenses suggest a variety of more plausible Scalar Utilitarian interpretations, and I argue for a version that best represents a moral theory founded on evaluative (...) notions, and offers better answers to demandingness concerns than does the ordinary Scalar Utilitarian response. If Utilitarians seek reasonable development and explanation of their basic commitments, they may wish to reconsider Scalar Utilitarianism. (shrink)

I try to reconstruct the hidden agenda of nineteenth-century British controversy between Utilitarianism and Intuitionism, going beyond the image, successfully created by the two Mills, of a battle between Prejudice and Reason. When examined in depth, competing philosophical outlooks turn out to be more research programs than self-contained doctrinal bodies, and such programs appear to be implemented, and indeed radically transformed while in progress thanks to their enemies no less than to their supporters. Controversies, the propelling devices of research (...) programs, are real-words affairs, and philosophers do not engage in them just for the sake of the argument, but in order to win, and alignments are defined on the basis of strategic and tactical requirements that cross the boundaries of disciplines. I suggest that good objections and counter-objections, and most of all amendments of doctrines, were incidentally produced in the course of the fight, and they were no less valuable because of their being more side-effects than sought-for discoveries.

This paper considers two different kinds of philosophical interpretations of the movie Eternal Sunshine of the Spotless Mind. On the one hand, Eternal Sunshine as a thought experiment that can function as an argument against utilitarianism. On the other hand, Eternal Sunshine as an instance of the genre of the remarriage comedy. I will argue that these two kinds of interpretations are in conflict. More specifically, Eternal Sunshine, understood as a comedy of remarriage, cannot function as an argument against (...) utilitarianism, at least in the sense specified by Grau and Wartenberg. Finally, I will suggest a different way in which Eternal Sunshine, understood as a comedy of remarriage, might function as an argument against utilitarianism. (shrink)

Average utilitarianism and several related axiologies, when paired with the standard expectational theory of decision-making under risk and with reasonable empirical credences, can find their practical prescriptions overwhelmingly determined by the minuscule probability that the agent assigns to solipsism -- i.e., to the hypothesis that there is only one welfare subject in the world, viz., herself. This either (i) constitutes a reductio of these axiologies, (ii) suggests that they require bespoke decision theories, or (iii) furnishes a novel argument for (...) ethical egoism. (shrink)

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)

An opinionated encyclopedia entry on ideal utilitarianism in which various arguments for the view are discussed and evaluated.

Fixed-rate versions of rule-consequentialism and rule-utilitarianism evaluate rules in terms of the expected net value of one particular level of social acceptance, but one far enough below 100% social acceptance to make salient the complexities created by partial compliance. Variable-rate versions of rule-consequentialism and rule-utilitarianism instead evaluate rules in terms of their expected net value at all different levels of social acceptance. Brad Hooker has advocated a fixed-rate version. Michael Ridge has argued that the variable-rate version is better. (...) The debate continues here. Of particular interest is the difference between the implications of Hooker's and Ridge's rules about doing good for others. (shrink)

Classical utilitarianism attempts to reduce the moral significance of the individual to something more basic: the value of the individual is seen as fully grounded in considerations of utility maximization. This paper criticizes this aspect of utilitarianism and tries to do so through an appeal to considerations that would be acceptable to one who embraces utilitarianism. First, an example is developed in which (1) a pair of mutually exclusive actions each yield infinite utility; (2) neither action can (...) be said to yield more utility than the other, and (3) one of the actions is clearly preferable. This provides a case in which the moral significance of the individual cannot be fully reduced to considerations of utility maximizing features of the action. A second example, developed along the lines of the first example, involves only finite utilities. (shrink)

Utilizing the film I, Robot as a springboard, I here consider the feasibility of robot utilitarians, the moral responsibilities that come with the creation of ethical robots, and the possibility of distinct ethics for robot-robot interaction as opposed to robot-human interaction. (This is a revised and expanded version of an essay that originally appeared in IEEE: Intelligent Systems.).

Harsanyi claimed that his Aggregation and Impartial Observer Theorems provide a justification for utilitarianism. This claim has been strongly resisted, notably by Sen and Weymark, who argue that while Harsanyi has perhaps shown that overall good is a linear sum of individuals’ von Neumann-Morgenstern utilities, he has done nothing to establish any con- nection between the notion of von Neumann-Morgenstern utility and that of well-being, and hence that utilitarianism does not follow. The present article defends Harsanyi against the (...) Sen-Weymark cri- tique. I argue that, far from being a term with precise and independent quantitative content whose relationship to von Neumann-Morgenstern utility is then a substantive question, terms such as ‘well-being’ suffer (or suffered) from indeterminacy regarding precisely which quantity they refer to. If so, then (on the issue that this article focuses on) Harsanyi has gone as far towards defending ‘utilitarianism in the original sense’ as could coherently be asked. (shrink)

Utilitarianism has a fairly bad reputation in military ethics, mainly because it is thought to make military expedience override all other concerns. The atomic bombing of Hiroshima and Nagasaki is a famous instance of such a skewed utilitarian calculation that “the rules of war and the rights they are designed to protect” should have stopped (Walzer 1992: 263-8). Most of its critics seem to think that utilitarianism is not bad per se, but prone to be misapplied in a (...) self-serving way. That idea, William H. Shaw argues in his careful and mostly convincing defense of utilitarian thinking about the moral issues that war occasions, is misguided, as are most of the other common objections to utilitarian thinking about the moral issues war raises.

The centennial of Dewey & Tuft’s Ethics (1908) provides a timely opportunity to reflect both on Dewey’s intellectual debt to utilitarian thought, and on his critique of it. In this paper I examine Dewey’s assessment of utilitarianism, but also his developing view of the good (ends; consequences), the right (rules; obligations) and the virtuous (approbations; standards) as “three independent factors in morals.” This doctrine (found most clearly in the 2nd edition of 1932) as I argue in the last sections, (...) has significant forward-going implications for debates in ethics, insofar as it functions to deflate debates among ethicists that turns on claims about the conceptual primacy of any one of these three ethical concepts over the other two. To find what “permanent value each group contributes to the clarification and direction of reflective morality” was the task Dewey set for himself. But to carry that project through demands showing also why the application of considerations of ends, rules, and virtues to problems of practice is not quite as many self-described utilitarians, deontologists, and virtue ethicists conceive it.

A well-known problem for preference-utilitarianism is to what extent it should exclude from consideration certain preferences. In this paper I focus on past preferences. I outline three general and some particular positions that a preference-utilitarian reasonably would want to take with regard to past preferences and why I think that endorsing each of these positions create new problems for the preference-utilitarian. At the end I sketch on a possible solution to the axiological problems here presented. However, although the pluralistic (...) approach that I outline shares with preference-utilitarianism the idea that what is valuable is the satisfaction of preferences, it is not a viable option for a utilitarian. My conclusion is therefore that preference-utilitarianism faces a serious axilogical problem. (shrink)

The utilitarian calculators of genetic therapy would do well to reflect again on Mills' liberal democratic rules of thumb: utility will generally be maximized when people are free to make choices, with good information, good instruments of collective action (democracy), and relative equality. My rule of thumb is that if we give future generations genetic choices, they will generally choose health, happiness, intelligence, and longevity, for themselves and their descendants.

The objective of the paper is to critically explicate the views of JS Mill in his "Utilitarianism" in regards to his efforts to clarify the concept of utilitarianism. In the first part of the paper it examined how successful was Mill in clarifying the idea of utilitarianism. In the second part of the paper, a critical discussion is presented to justify the applicability of his theory in dealing with contemporary moral dilemmas.

The paper focuses on the differences between utilitarianism and non-utilitarian consequentialism.

For a long time many philosophers felt the incoherence objection was a decisive objection to rule-consequentialism, but that position has recently become less secure, because Brad Hooker has offered a clever new way for rule-consequentialists to avoid the incoherence objection. Hooker’s response defeats traditional forms of the incoherence objection, but this paper argues that another version of the problem remains. Several possible solutions fail. One other does not, but it introduces other problems into the theory. I conclude that the new (...) incoherence objection still poses a major challenge to rule-consequentialism, though not for the reasons usually assumed. It does not constitute a fatal objection to rule-consequentialism but instead highlights a theoretical drawback in the theory which must be taken into account during a more holistic evaluation of rule-consequentialism and its rivals.

This is a presentation of the utilitarian approach to punishment. It is meant for students. The first section discusses Bentham's psychological hedonism. The second briefly criticizes it. The third section explains abstractly how utilitarianism would determine of the right amount of punishment. The fourth section applies the theory to some cases, and brings out how utilitarianism could favor punishments more or less severe than the lex talionis.

According to hedonistic act utilitarianism, an act is morally right if and only if, and because, it produces at least as much pleasure minus pain as any alternative act available to the agent. This dissertation gives a partial defense of utilitarianism against two types of objections: action guidance objections and intuitive objections. In Chapter 1, the main themes of the dissertation are introduced. The chapter also examines questions of how to understand utilitarianism, including (a) how to best (...) formulate the moral explanatory claim of the theory, (b) how to best interpret the phrase "pleasure minus pain," and (c) how the theory is related to act consequentialism. The first part (Chapters 2 and 3) deals with action guidance objections to utilitarianism. Chapter 2 defines two kinds of action guidance: doxastic and evidential guidance. It is argued that utilitarianism is evidentially but not doxastically guiding for us. Chapter 3 evaluates various action guidance objections to utilitarianism. These are the objections that utilitarianism, because it is not doxastically guiding, is a bad moral theory, fails to be a moral theory, is an uninteresting and unimportant moral theory, and is a false moral theory. The second part (Chapters 4, 5 and 6) deals with intuitive objections to utilitarianism. Chapter 4 presents three intuitive objections: Experience Machine, Transplant, and Utility Monster. Three defenses of utilitarianism are subsequently evaluated. Chapter 5 and 6 introduces two alternative defenses of utilitarianism against intuitive objections, both of which concern the role that imagination plays in thought experimentation. In Chapter 5, it is argued that we sometimes unknowingly carry out the wrong thought experiment when we direct intuitive objections against utilitarianism. In many such cases, we elicit moral intuitions that we believe give us reason to reject utilitarianism, but that in fact do not. In Chapter 6, it is argued that using the right kind of sensory imagination when we perform thought experiments will positively affect the epistemic trustworthiness of our moral intuitions. Moreover, it is suggested that doing so renders utilitarianism more plausible. In Chapter 7, the contents of the dissertation are summarized. (shrink)

This paper presents an objection to John Rawls’s use of the original position method to argue against implementing utilitarian rules. The use of this method is pointless because a small subset of the premises Rawls relies on can be used to infer the same conclusion.

In a number of recent publications, Cass Sunstein and Richard Thaler have argued for a novel approach to the design of public policy. Their proposal has received a great deal of attention, both within academic circles and the public at large. Drawing upon evidence from behavioral economics and empirical psychology, the authors attempt to demonstrate that the conventional antagonism between libertarians and paternalists within political theory dissolves in conditions that obtain widely in public decision-making. Where free choice and the promotion (...) of individual welfare can coexist, the authors believe that designers of public policy ought to be libertarian paternalists. In this paper I criticize their proposal on grounds that the authors are unable to sufficiently motivate the paternalistic element of their approach. I argue that the empirical evidence cited by the authors is capable of supporting a number of competing approaches, including what I call libertarian utilitarianism and libertarian justice. Since the evidence that the authors draw upon does not provide us any grounds for selecting between these rival approaches, I conclude that Sunstein and Thaler are unable to provide us with a convincing guide for the design of public policy. In order to show that this is the case, I consider three arguments in favor of libertarian paternalism, and find each lacking. I end with some comments about what we can properly conclude on the basis of Sunstein and Thaler’s arguments. (shrink)

An outline of the historical development of ideas of utility and consequences in the history of ethics in the 18th century.

Utilitarianism has often been understood as a theory that concerns itself first and foremost with the rightness of actions; but many other things are also properly subject to moral evaluation, and utilitarians have long understood that the theory must be able to provide an account of these as well. In a landmark article from 1976, Robert Adams argues that traditional act utilitarianism faces a particular problem in this regard. He argues that a on a sensible utilitarian account of (...) the rightness of an agent’s motives, right motives will sometimes conflict with right actions, leaving the theory internally incoherent. The puzzle Adams raises has received a good deal of attention but few proposed solutions. Fred Feldman, however, has offered a solution that seems to be gaining adherents. In this paper I argue that Feldman’s approach cannot succeed. At bottom, it relies on a version of the principle that ‘ought’ implies ‘can’—and subsequently an account of an agent’s alternatives—that is far too restrictive to be plausible. Despite the failure of this solution, however, I argue that the conflict Adams develops is not as theoretically troubling as he suggests. While traditional act utilitarianism may fail for other reasons, it will not fail due to the conflict between acts and motives. (shrink)

Formulations of Mill's principle of utility are examined, and it is shown that Mill did not recognize a moral obligation to maximize the good, as is often assumed. His was neither a maximizing act nor rule utilitarianism. It was a distinctive minimizing utilitarianism which morally obligates us only to abstain from inflicting harm, to prevent harm, to provide for others minimal essentials of well being (to which rights correspond), and to be occasionally charitable or benevolent.

This paper raises a moral issue for contemporary post-revolutionary Muslim intellectuals in Iran. According to traditional Islamic teachings, ethics enables people to transcend from this mundane world and offers guidance on ways to improve virtues. Most contemporary Iranian Muslim intellectuals have attempted to pave the way for accomplishing this goal. After clarifying the ways in which Iranian Muslim intellectuals have faith in virtue ethics as a best possible moral normative theory, we claim that virtue ethics fails to support some of (...) our modern problems in the realm of politics such as human rights and democracy. Also, we argue that virtue ethics is not a good theory for ordinary average people who have weakness of will. A preliminary conclusion of the paper will be that utilitarianism, generally, and principle of utility, specifically, is a better solution to the modern problems. This, we believe, has been overlooked from the eyes of post-revolutionary Muslim intellectuals. Yet, we suggest that among different versions of utilitarianism, rule-utilitarianism is more justified to do this job. (shrink)

I examine the two-level utilitarian case for humane animal agriculture (by R. M. Hare and Gary Varner) and argue that it fails on its own terms. The case states that, at the ‘intuitive level’ of moral thinking, we can justify raising and killing animals for food, regarding them as replaceable, while treating them with respect. I show that two-level utilitarianism supports, instead, alternatives to animal agriculture. First, the case for humane animal agriculture does not follow from a commitment to (...) two-level utilitarianism combined with a commitment to respecting animal lives. Secondly, the two-level utilitarian case falls prey to a compartmentalization problem and cannot uphold both respect and replaceability. What I call ‘humane lives’ are not appropriately valued by the lights of two-level utilitarianism itself. (shrink)

A comparative essay on: Kantianism vs Utilitarianism.

In the attempt of defending an interpretation of David Hume's moral and political philosophy connected to classical utilitarianism, intervenes in a key way the so called problem of the " Sensitive Knave " raised by this author at the end of his more utilitarian work, the Enquiry Concerning the Principles of Morals. According to the classic interpretation of this fragment, the utilitarian rationality in politics would clash with morality turning useless the latter. Therefore, in the political area the defense (...) of a moral utilitarianism would be an auto contradictory task. In order to show that, first, Hume does not say anything similar to this and second, that even indicates the way of overcoming this apparent contradiction between morality and rationality, we analyze briefly the arguments from which there comes basically this "anti-utilitarian" standard interpretation, and we defend an interpretation of the humean discussion on the problem of the supposed conflict between morality and rationality, or of rational incentives for immoral behavior, which allows to explain better Hume's position on this problem. Finally, we propose an instance of overcoming the contradiction morality/ rationality by a rule adjusted utilitarianism centered on the idea of the "progressive development of artificial institutions of reinforcement of morality", that Hume himself would suggest in other places in which he approaches the topic of the apparent contradiction between "morality" and "knavery". We propose also possible lines of future development of this idea, between them its use to clarify the relation of David Hume's thought with certain forms of contemporary liberalism. (shrink)

Sufficientarianism is a view of distributive justice that places importance on one or more ‘thresholds’, whereby those who are above the threshold have much weaker claims to additional benefits than those below, and may even have no claims at all. Hun Chung has recently argued for a new theory of distributive justice that overcomes two central problems faced by sufficientarianism. Sufficientarianism cannot give intuitively compelling answers to ‘lifeboat cases’, where we can save the lives of some but not all of (...) a group, and fails to respect the axiom of continuity. Chung says that his alternative, ‘prospect utilitarianism’, gives correct answers to lifeboat cases, and respects continuity. What is more, his theory gets empirical support from work in economics on ‘prospect theory’. This paper does several things. Firstly, it shows that sufficientarianism can give the intuitively correct answer to lifeboat cases, and that prospect utilitarianism’s ability to do so is less compelling than Chung suggests. Secondly, it shows that the idea of continuity is not an axiom, and thus that sufficientarianism’s failure to respect it is not a good reason to reject the view. Finally, it shows that prospect utilitarianism faces some independent problems, since it too requires a threshold. Chung’s threshold is based on the idea of ‘adequate functioning’. The paper shows that there are problems with this as a threshold, and that it is not adequately supported by prospect theory. As such, the prospects for prospect utilitarianism are poor. (shrink)

Modern bioethics is clearly dominated by deontologists who believe that we have some way of identifying morally correct and incorrect acts or rules besides taking account of their consequences. Robert M. Veatch is one of the most outspoken of those numerous modern medical ethicists who agree in rejecting all forms of teleological, utilitarian, or consequentialist ethical theories. This paper examines his critique of utilitarianism and shows that the utilitarianism of John Stuart Mill is either not touched at all (...) by his critique or can be defended against it. This article argues that the dominant deontological majority is mistaken and that a utilitarian theory of moral action very much like Mill’s is precisely what is needed by modern medical ethics and by those medical practitioners who are resolved to practice medicine in a reasonable and morally acceptable manner.

Most arguments in support of act utilitarianism are elaborations of one of two basic strategies. One is the consequentialist strategy. This strategy relies on the consequentialist premise that an act is right if and only if it produces the best possible consequences and the welfarist premise that the value of a state of affairs is entirely determined by its overall amount of well-being. The other strategy is based on the idea of treating individuals respectfully and resolving conflicts among individuals (...) in whatever way best conforms to that idea. Although both of these strategies can be used to argue for the principle of act utilitarianism, they are significantly different from each other, and these differences cause them to have different strengths and weaknesses. It emerges that which argumentative strategy is chosen by a proponent of act utilitarianism has a large impact on which virtues her view has and which objections it is vulnerable to. (shrink)

Modelling ethics is critical to understanding and analysing social phenomena. However, prior literature either incorporates ethics into agent strategies or uses it for evaluation of agent behaviour. This work proposes a framework that models both, ethical decision making as well as evaluation using virtue ethics and utilitarianism. In an iteration, agents can use either the classical Continuous Prisoner's Dilemma or a new type of interaction called moral interaction, where agents donate or steal from other agents. We introduce moral interactions (...) to model ethical decision making. We also propose a novel agent type, called virtue agent, parametrised by the agent's level of ethics. Virtue agents' decisions are based on moral evaluations of past interactions. Our simulations show that unethical agents make short term gains but are less prosperous in the long run. We find that in societies with positivity bias, unethical agents have high incentive to become ethical. The opposite is true of societies with negativity bias. We also evaluate the ethicality of existing strategies and compare them to those of virtue agents. (shrink)
