Act- and Rule-Utilitarianism

"Resolution of Jerusalem’s status arguably remains controversial because of the divergent analytical lenses through which the conflict’s parties, and others, view its intertwined legal, territorial, historical and religious issues. Thus, Jerusalem persists as an intricate and intractable cornerstone of the Israel-Palestine conflict." Diakonia International Humanitarian Law Resource Centre.

A future in which humanity does not go extinct from something like a meteor strike or nuclear war might contain vast quantities of great happiness and human flourishing. But it might also contain vast quantities of great misery and wasted potential. Any effort to ensure a long happy future will have to strive both to ensure a long future, by reducing extinction risks, and to ensure it is a happy one, by improving the quality of life. Such an effort might (...) succeed at the former goal without succeeding at the latter. So any effort to ensure a long happy future will increase the chance of such a future, but it will also increase the chance of a long miserable future, even if it increases the latter by a smaller amount. Granted this, if you are risk-averse, or if morality requires you to choose using risk-averse preferences, then you do better to work to bring about humanity's extinction than to secure its long-term survival. This conclusion will seem troubling to many, though perhaps welcome to some. In this paper, I try to formulate the argument as plausibly and as robustly as I can. I then investigate how those who wish to resist it might do so. (shrink)

Mill and Principle of Utility Chapter 10. Kant and Moral Theory The historian Herodotus gives (...) the anecdote of Darius, King of Persia, who summoned the Greeks and asked them if they would be willing to eat the bodies of their dead fathers. They replied they would not for any money in the world. Later, Darius asked some Indians of the tribe called Callatiae, who do eat their dead parents’ bodies, if they would ever consider burning the bodies, as was the custom among Greeks. “One can see by this what custom can do” writes Herodotus. He draws the conclusion that this story vindicates the view some acts may be right for some and wrong for others, depending on their individual conceptions of morality. The Sophists were also associated with relativistic thinking, notably Protagoras who asserts that “man is the measure of all things”. However, this view was quite uncommon and moral relativism hardly flourished, as Plato and Aristotle both defended forms of moral absolutism. Ancient Greek philosophers acknowledged moral diversity, but more often under the form of moral scepticism, which states that there is no moral knowledge (rather than moral truth is relative to a culture).

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

This essay addresses the collapse/incoherence problem for normative frameworks that contain both fundamental values and rules for promoting those values. The problem is that in some cases, we would bring about more of the fundamental value by violating the framework’s rules than by following them. In such cases, if the framework requires us to follow the rules anyway, then it appears to be incoherent; but if it allows us to make exceptions to the rules, then the framework “collapses” into one (...) that doesn’t make use of rules in the first place. The chapter begins with an examination of happiness and truth as fundamental values in Mill’s work, which lead into parallel versions of the collapse/incoherence problem in ethics and epistemology. It then sets out the collapse problem for rule-consequentialist approaches in ethics, truth-directed accounts of justification in epistemology, and epistemological approaches to argument cogency. The chapter closes with discussion of two potential solutions to the problem. (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)

Consequentialist theories determine rightness solely based on real or expected consequences. Although such theories are popular, they often have difficulty with generalizing intuitions, which demand concern for questions like “What if everybody did that?” Rule consequentialism attempts to incorporate these intuitions by shifting the locus of evaluation from the consequences of acts to those of rules. However, detailed rule-consequentialist theories seem ad hoc or arbitrary compared to act consequentialist ones. We claim that generalizing can be better incorporated into consequentialism by (...) keeping the locus of evaluation on acts but adjusting the decision theory behind act selection. Specifically, we should adjust which types of dependencies the theory takes to be decision-relevant. Using this strategy, we formulate a new theory, generalized act consequentialism, which we argue is more compelling than rule consequentialism both in modeling the actual reasoning of generalizers and in delivering correct verdicts.

Los autores hacen en este ensayo un análisis crítico del texto original de John Stuart Mill [1861/1863] titulado “El utilitarismo”, en el que el autor inglés busca hacer compatibles dos doctrinas: la doctrina del mayor bien para el mayor número de personas y, la doctrina del ius naturalismo que considera que existe un canon moral a priori que introduce conceptos absolutos como el bien intrínseco o el mal en sí como criterios para la toma de decisiones. En este trabajo, se (...) subraya la influencia que el pragmatismo clásico ejerció, y ejerce, como teoría de pensamiento jurídico y, sobre todo, para la acción y la decisión. El utilitarismo, interpreta al mundo desde diversos enfoques epistemológicos, especialmente desde el derecho, la economía y la política. Los autores concluyen que el utilitarismo queda justificado como precepto válido para la aplicación del derecho positivo, en el que debe juzgarse la acción no por su intencionalidad, sino por sus consecuencias evidentes.

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)

Christopher Woodard presents a new and rich version of utilitarianism, the idea that ethics is ultimately about what makes people's lives go better. He launches a state-of-the-art defence of the theory, often seen as excessively simple, and shows that it can account for much of the complexity and nuance of everyday ethical thought.

Traditional rule consequentialism faces a problem sometimes called the ideal world objection—the worry that by looking only at the consequences in worlds where rules are universally adhered to, the theory fails to account for problems that arise because adherence to rules in the real world is inevitably imperfect. In response, recent theorists have defended sophisticated versions of rule consequentialism which are sensitive to the consequences in worlds with less utopian levels of adherence. In this paper, I argue that these attempts (...) underestimate the problem they are designed to avoid—the worry about ideal worlds is only one manifestation of a deeper and more general problem, the distant world objection, which threatens not only the sophisticated revisions of rule consequentialism, but any view which determines what we ought to do by evaluating worlds that differ from ours in more than what is up to us.

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.

I will discuss the prospect of pharmaceutically enhancing human morality and decision making in such a way as to eliminate morally unjustifiable choices and promote desirable ones. Our species in the relatively short period since it has emerged has enormously advanced in knowledge, science, and technical progress. When it comes to moral development, the distance it has covered is almost negligible. What if we could medically accelerate our moral development? What if we could once and for all render our species (...) totally immune to certain vices? I will examine whether pharmaceutically intervening in human morality would compromise the autonomy of moral agents. I will argue that the argument from the autonomy of the moral agent is neither stable nor convincing. In the light of Kantian ethics we might consider moral enhancement by pharmaceutical means to be a perfect duty for moral agents. (shrink)

Recent scholarship on John Stuart Mill’s moral theory has settled on the view that he is committed to a form of rule utilitarianism. I argue that this consensus is mistaken. Mill’s explicit account of practical rules is incompatible with rule utilitarianism but consistent with sophisticated act utilitarianism. I also examine the direct, textual evidence cited by rule utilitarian interpreters, arguing that it is consistent with the act utilitarian account of practical rules. Finally, I argue that two systematic considerations cited by (...) rule utilitarian interpreters—Mill’s analysis of “wrong” in terms of the appropriateness of punishment, and his account of supererogation—also do not require a rule utilitarian reading.

This dissertation argues for a particular interpretation of John Stuart Mill’s utilitarianism, namely that Mill is best read as a sanction utilitarian. In general, scholars commonly interpret Mill as some type of act or rule utilitarian. In making their case for these interpretations, it is also common for scholars to use large portions of Mill’s Utilitarianism as the chief source of insight into his moral theory. By contrast, I argue that Utilitarianism is best read as an ecumenical text where Mill (...) explains and defends the general tenets of utilitarianism rather than setting out his own preferred theory. The exception to this ecumenical approach to the text comes in the fifth chapter on justice which, I argue on textual and historical grounds, outlines the central features of Mill’s utilitarianism. -/- With this understanding of Utilitarianism in place, many of the passages commonly cited in favor of the previous interpretations are rendered less plausible, and interpretations emphasizing Mill’s other writings are strengthened. Using this methodology, I critique four of the most prominent act or rule utilitarian interpretations of Mill’s moral theory. I then provide an interpretation of Mill’s theory of moral obligation and utilitarianism. On Mill’s account of moral obligation (which purportedly holds for moral theories generally, not just utilitarianism) there is a tight relation between an action being wrong and it being subject to punishment by an agent’s conscience. The utilitarian aspect of Mill’s theory concerns the role of rules in an agent’s conscience. According to Mill’s sanction utilitarian view, the actions that are punished are those actions that violate the moral rules which, if widely internalized across society, would promote general utility. On this account, an action is wrong when an agent violates a justified moral rule and is properly punished, at least by one’s conscience. An action is right when conditions are such that if the action were not performed, then the action would be properly punished by at least the agent’s conscience. I apply this interpretation to other notable components of Mill’s approach such as his account of practical action (the Art of Life) and his theory of liberty. (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).

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)

Act and Rule Utilitarianism Utilitarianism is one of the best known and most influential moral theories. Like other forms of consequentialism, its core idea is that whether actions are morally right or wrong depends on their effects. More specifically, the only effects of actions that are relevant are the good and bad results that they […].

Mill argues that, apart from the principle of utility, his utilitarianism is incompatible with absolutes. Yet in On Liberty he introduces an exceptionless anti-paternalism principle—his liberty principle. In this paper I address ‘the absolutism problem,’ that is, whether Mill's utilitarianism can accommodate an exceptionless principle. Mill's absolute claim is not a mere bit of rhetoric. But the four main solutions to the absolutism problem are also not supported by the relevant texts. I defend a fifth solution—the competence view—that turns on (...) his attention to decision-making structures and, in particular, on the role of expertise considerations in his account. (shrink)

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)

This book offers a clear and highly readable introduction to the ethical and social-political philosophy of John Stuart Mill. Dale E. Miller argues for a "utopian" reading of Mill's utilitarianism. He analyses Mill's views on happiness and goes on to show the practical, social and political implications that can be drawn from his utilitarianism, especially in relation to the construction of morality, individual freedom, democratic reform, and economic organization. By highlighting the utopian thinking which lies at the heart of Mill's (...) theories, Miller shows that rather than allowing for well-being for the few, Mill believed that a society must do everything in its power to see to it that each individual can enjoy a genuinely happy life if the happiness of its members is to be maximized. Miller provides a cogent and careful account of the main arguments offered by Mill, considers the critical responses to his work, and assesses its legacy for contemporary philosophy. Lucidly and persuasively written, this book will be a valuable resource for students and scholars seeking to understand the continued importance of Mill's thinking. (shrink)

In this article, I argue that the reading of Mill that D.G. Brown presents in ‘Mill’s Moral Theory: Ongoing Revisionism’ is inconsistent with several key passages in Mill’s writings. I also show that a rule-utilitarian interpretation that is very close to the one developed by David Lyons is able to account for these passages without difficulty.

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)

Gregory Kavka's 'Toxin Puzzle' suggests that I cannot intend to perform a counter-preferential action A even if I have a strong self-interested reason to form this intention. The 'Rationalist Solution,' however, suggests that I can form this intention. For even though it is counter-preferential, A-ing is actually rational given that the intention behind it is rational. Two arguments are offered for this proposition that the rationality of the intention to A transfers to A-ing itself: the 'Self-Promise Argument' and David Gauthier's (...) 'Rational Self-Interest Argument.' But both arguments – and therefore the Rationalist Solution – fail. The Self-Promise Argument fails because my intention to A does not constitute a promise to myself that I am obligated to honor. And Gauthier's Rational Self-Interest Argument fails to rule out the possibility of rational irrationality. (shrink)

O objetivo do presente trabalho é examinar se o utilitarismo de regras poderia ter êxito em prover um possível avanço sobre o utilitarismo de atos, de modo a tornar o utilitarismo uma teoria moral viável. Em face deste propósito, levarei em consideração o seguinte: Em primeiro lugar temos que perceber que existem diferentes formulações do utilitarismo de regras, as quais visam responder a contra-exemplos morais, que o utilitarismo de atos não resolve satisfatoriamente. Em minha opinião, se contra-exemplos são bem sucedidos (...) na formulação do utilitarismo de regras como uma alternativa substantiva ao utilitarismo de atos, e se esta alternativa substantiva permanece sob a égide do princípio utilitarista, em seguida, eles teriam conseguido responder a contra-exemplos. Em segundo lugar, apresentarei as principais formulações defendidas por escritores contemporâneos The purpose of the present work is to examine whether rule-utilitarianism could succeed in providing a possible improvement over act utilitarianism so as to render utilitarianism a viable moral theory. In view of this purpose, I will take the following into consideration: Firstly, we must realise that there are quite a few different formulations of rule-utilitarianism, all of which aim at replying to the moral counterexamples that act-utilitarianism fails to resolve satisfactorily. In my opinion, if counter-examples succeed in formulating rule-utilitarianism as a substantive alternative to act-utilitarianism, and if this substantive alternative remains within the utilitarian principle, then they would have succeeded in replying to the counter-examples. Secondly, I shall present the main formulations advanced by contemporary writers. (shrink)

The question of the ethical life is arguably one of the most compelling, and urgent, questions of our time. As Peter Singer, among others, has pointed out, almost 10 million children die each year due to poverty, some of whom would not die if the amount of aid that we now offer increases significantly. As Singer has also pointed out, the exploitation of human beings and other animals is a major ethical and practical concern. There can be little reasonable doubt (...) that pain and suffering abound, in the world today, due to many causes such as poverty, disease, environmental degradation and destruction and anthropocentrism among others, just as there can be little reasonable doubt that some of the pain and suffering is preventable. So, what does it mean to live ethically today? Does it mean taking the point of view of the universe, as Sidgwick put it, memorably, rather than a narrow anthropocentric or speciesist view? Does it mean living in accordance with duties or obligations, or in light of recognised virtues, or with the minimisation of pain and suffering primarily in mind? Does it entail a consideration of the interests of other species and a rejection of the principle of the sanctity of human life? Does it mean not eating animals when other healthy alternatives are available, especially when those animals have been treated in ways that are inconsistent with their interests, whatever they may be? Does it mean taking active steps to reduce poverty on our part on a day to day basis? Is ethics exhausted in some sense today? And if we could reach some consensus on these questions, what difference would the ethical life make? Some argue that speciesism and the exploitation of human beings and other animals might diminish; that pain and suffering, especially gratuitous pain and suffering, would decrease, or at the very least, not increase; or that we will become more aware of the limitations of things such as "the traditional ethic of the sanctity of life", as Singer calls it. Some argue that the ethical life is closely related to a life of relationships, reflection and deliberation, all of which deepen our understanding and enrich us personally. Others argue that the ethical life is closely related to our search for a meaningful life - that the ethical life can help us to find meaning in a world in which "meaning", defined broadly, can seem elusive, enigmatic or unsubstantial. These and related issues and questions are explored in this collection, which illustrates the relevance, vitality and dynamism of ethics today. (shrink)

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)

This dissertation is primarily a defense of a rule-utilitarian theory of just war. The dissertation will also include an historical application of this theory of just war. In the most general of terms, these are the main goals of my dissertation. I will devise and defend a rule-utilitarian theory of just war, and I will apply that theory to the American war in Vietnam. Within this context, there are several more specific tasks to be completed. I will define and explain (...) important representative portions of the Catholic and the secular just war tradition. The Bishops' letter The Challenge of Peace constitutes a culmination of many centuries of Christian thinking on morality in war, and it will serve as a sort of framework for my theory of just war. Michael Walzer's Just and Unjust Wars is an important centerpiece of secular just war thinking, and parts of it will be put to work in my theory as well. As my theory is a rule-utilitarian one, it is necessary to get clear on what exactly utilitarianism as a moral theory is, what the difference between rule and act-utilitarianism is, and to defend rule over act-utilitarianism. Specifically, the dissertation has the following goals: To define and explain important parts of the Christian just war tradition. To explain key portions of perhaps the most important secular work on just war, Michael Walzer's Just and Unjust Wars. To define utilitarianism as a moral theory as clearly as possible, while illustrating the difference between act and rule-utilitarianism. To defend rule over act-utilitarianism. To devise and defend a rule-utilitarian theory of just war. To illustrate the virtues of my theory of just war by applying it to the American war in Vietnam. I argue that the American war in Vietnam failed to meet the criteria for just wars. (shrink)

Ideal rule utilitarianism says that a moral code C is correct if its acceptance maximizes utility; and that right action is compliance with C. But what if we cannot accept C? Rawls and L. Whitt suggest that C is correct if accepting C maximizes among codes we can accept; and that right action is compliance with C. But what if merely reinforcing a code we can't accept would maximize? G. Trianosky suggests that C is correct if reinforcing it maximizes; and (...) that right action is action that has the effect of reinforcing compliance with C. I object to this and argue that C is correct if both accepting and reinforcing C would maximize and if C is reinforcible; and that right action consists in coming as close as possible to perfect acceptance of and compliance with C.

In his recent book,Rational Behaviour and Bargaining Equilibrium In Games and Social Situations, John C. Harsanyi devotes a chapter to his new theory of morality, which he calls ‘Critical Rule Utilitarianism’, and which contains his solution to the problem of the interpersonal comparison of utility.
