Act- and Rule-Utilitarianism

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

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)

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)

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)

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)

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 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.

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 […].

On the one hand, people have witnessed a lot of amazing technological inventions and innovations in the multifaceted performances of artificial intelligence systems ever since the earliest stages of their development. Activities previously done with a lot of manual and muscular efforts are now accomplished with no sweat and just at the tip of one’s finger. I would venture to say that artificial intelligence is among the highest scientific and technological achievements of humanity in the post-modern civilization. Yet on the (...) other hand, are we worried that humanity will soon be threatened by the dark side of AI systems when the truth of the matter is long before the advent of AI, humanity has always been threatened by the evil forces of totalitarian powers well-entrenched in governments and big capitalist empires in control of nations’ economies? Future AI systems employed and mobilized in the service of these political and economic powers will certainly heighten the degree of their oppressive domination and intensify the common people’s oppression.

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.

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)

In his "consequences of utilitarianism", D. H. Hodgson argues that to act on the principle of act-Utilitarianism would have disastrous consequences, And that this principle must therefore be rejected. I attempt to refute his argument. The debate centers on whether there can be an act-Utilitarian justification for telling the truth and keeping promises.

Two essays on utilitarianism, written from opposite points of view, by J. J. C. Smart and Bernard Williams. In the first part of the book Professor Smart advocates a modern and sophisticated version of classical utilitarianism; he tries to formulate a consistent and persuasive elaboration of the doctrine that the rightness and wrongness of actions is determined solely by their consequences, and in particular their consequences for the sum total of human happiness. In Part II Bernard Williams offers a sustained (...) and vigorous critique of utilitarian assumptions, arguments and ideals. He finds inadequate the theory of action implied by utilitarianism, and he argues that utilitarianism fails to engage at a serious level with the real problems of moral and political philosophy, and fails to make sense of notions such as integrity, or even human happiness itself. This book should be of interest to welfare economists, political scientists and decision-theorists. (shrink)

Rule utilitarianism has recently enjoyed a resurgence of interest triggered by Brad Hooker’s sophisticated treatment in Ideal Code, Real World.1 An intriguing new debate has now broken out about how best to formulate rule utilitarianism – whether to evaluate candidate moral codes in terms of the value of their consequences at a fixed rate (such as 90%) of social acceptance (as Hooker contends), or to evaluate codes in terms of the value of their consequences throughout the entire range of possible (...) acceptance rates (as Hooker’s opponent Ridge contends).2 I shall argue that both Hooker’s fixed-rate ruleutilitarianism and Ridge’s variable-rate rule-utilitarianism, suitably interpreted and revised, survive the criticisms that each theorist lodges against the other. But I shall use the insights gained through this examination to argue that both these forms of rule utilitarianism, arguably the best available, fall prey to two fatal problems that have gone unnoticed in these debates, or indeed in most debates about rule utilitarianism. The weaknesses I describe in Hooker and Ridge’s forms of rule utilitarianism threaten to undermine all versions of rule utilitarianism, not just the nuanced versions developed by Hooker and Ridge.

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. After a detailed exposition of his theory, arguments will be presented to show that:there are certain formal difficulties in the solution that he offers which leads to a rejection of the axiom that there is to (...) be agreement between an individualj’s personal preferences and individuali’s (i ≠j) extended utility function out of which the social welfare function is to be constructed; andHarsanyi’s theory of critical rule utilitarianism cannot be accepted as a theory of morality because it presupposes a more fundamental theory in its actual construction.

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 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)

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.

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)
