Rule-Consequentialism faces “the problem of partial acceptance”: How should the ideal code be selected given the possibility that its rules may not be universally accepted? A new contender, “Calculated Rates” Rule-Consequentialism claims to solve this problem. However, I argue that Calculated Rates merely relocates the partial acceptance question. Nevertheless, there is a significant lesson from this failure of Calculated Rates. Rule-Consequentialism’s problem of partial acceptance is more helpfully understood as an instance of the broader (...) problem of selecting the ideal code given various assumptions—assumptions about who will accept and comply with the rules, but also about how the rules will be taught and enforced, and how similar the future will be. Previous rich discussions about partial acceptance provide a taxonomy and groundwork for formulating the best version of Rule-Consequentialism. (shrink)

Brad Hooker; II*—Rule-Consequentialism, Incoherence, Fairness1, Proceedings of the Aristotelian Society, Volume 95, Issue 1, 1 June 1995, Pages 19–36, https://d.

Most plausible moral theories must address problems of partial acceptance or partial compliance. The aim of this paper is to examine some proposed ways of dealing with partial acceptance problems as well as to introduce a new Rule Utilitarian suggestion. Here I survey three forms of Rule Utilitarianism, each of which represents a distinct approach to solving partial acceptance issues. I examine Fixed Rate, Variable Rate, and Optimum Rate Rule Utilitarianism, and argue that a new approach, Maximizing (...) Expectation Rate Rule Utilitarianism, better solves partial acceptance problems. (shrink)

This paper explores what a Rule Consequentialist of Brad Hooker's sort can and should say about normative rea- sons for action. I claim that they can provide a theory of reasons, but that doing so requires distinguishing dif- ferent roles of rules in the ideal code. Some rules in the ideal code specify reasons, while others perform differ- ent functions. The paper also discusses a choice that Rule Consequentialists face about how exactly to specify rea- sons. It ends (...) by comparing the theory of reasons offered by Rule Consequentialism with the theory offered by Act Consequentialism, noting that Rule Consequentialism seems better able to explain moral constraints. (shrink)

As an indirect ethical theory, rule consequentialism first evaluates moral codes in terms of how good the consequences of their general adoption are and then individual actions in terms of whether or not the optimific code authorises them. There are three well-known and powerful objections to rule consequentialism’s indirect structure: the ideal world objection, the rule worship objection, and the incoherence objection. These objections are all based on cases in which following the optimific code has (...) suboptimal consequences in the real world. After outlining the traditional objections and the cases used to support them, this paper first constructs a new hybrid version of consequentialism that combines elements of both act and rule consequentialism. It then argues that this novel view has sufficient resources for responding to the previous traditional objections to pure rule consequentialism. (shrink)

Brad Hooker’s rule-consequentialism and T.M. Scanlon’s contractualism have been some of the most debated ethical theories in normative ethics during the last twenty years or so. This article suggests that these theories can be compared at two levels. Firstly, what are the deep, structural differences between the rule-consequentialist and contractualist frameworks in which Hooker and Scanlon formulate their views? Secondly, what are the more superficial differences between Hooker’s and Scanlon’s formulations of these theories? Based on exploring these (...) questions and several purported differences between Hooker’s and Scanlon’s views, this article argues that, at the structural level, the two theories are more similar than previous recognised. It suggests that there is only one candidate for a deeper difference and even it may not be that significant. This insight sheds new light on both contractualism and rule-consequentialism, and it will also help us to formulate better versions of the views. (shrink)

I argue that rule consequentialism sometimes requires us to act in ways that we lack sufficient reason to act. And this presents a dilemma for Parfit. Either Parfit should concede that we should reject rule consequentialism (and, hence, Triple Theory, which implies it) despite the putatively strong reasons that he believes we have for accepting the view or he should deny that morality has the importance he attributes to it. For if morality is such that we (...) sometimes have decisive reason to act wrongly, then what we should be concerned with, practically speaking, is not with the morality of our actions, but with whether our actions are supported by sufficient reasons. We could, then, for all intents and purposes just ignore morality and focus on what we have sufficient reason to do, all things considered. So if my arguments are cogent, they show that Parfit’s Triple Theory is either false or relatively unimportant in that we can, for all intents and purposes, simply ignore its requirements and just do whatever it is that we have sufficient reason to do, all things considered. (shrink)

We best understand Rule Consequentialism as a theory of pattern-based reasons, since it claims that we have reasons to perform some action because of the goodness of the pattern consisting of widespread performance of the same type of action in the same type of circumstances. Plausible forms of Rule Consequentialism are also pluralist, in the sense that, alongside pattern-based reasons, they recognise ordinary act-based reasons, based on the goodness of individual actions. However, Rule Consequentialist theories (...) are distinguished from other pluralist theories of pattern-based reasons by implausible claims about the relative importance of act-based and pattern-based reasons in different cases. Rule Consequentialists should give up these claims. They should either embrace some other pluralist pattern-based view, or reject pattern-based reasons altogether. Note, though, that these arguments apply only to compliance-based, rather than acceptance-based, versions of Rule Consequentialism. This suggests that these two kinds of theory are more different from each other than we might previously have realised. (shrink)

Rule-consequentialists tend to argue for their normative theory by claiming that their view matches our moral convictions just as well as a pluralist set of Rossian duties. As an additional advantage, rule-consequentialism offers a unifying justification for these duties. I challenge the first part of the ruleconsequentialist argument and show that Rossian duties match our moral convictions better than the rule-consequentialist principles. I ask the rule-consequentialists a simple question. In the case that circumstances change, is (...) the wrongness of acts determined by the ideal principles for the earlier circumstances or by the ideal ones for the new circumstances? I argue that whichever answer the rule-consequentialists give the view leads to normative conclusions that conflict with our moral intuitions. Because some set of Rossian duties can avoid similar problems, rule-consequentialism fails in the reflective equilibrium test advocated by the rule-consequentialists. (shrink)

Prima facie, rule-consequentialism as a moral theory would correlate with the concerns of an omnibenevolent being should one exist. Indeed, such a being would be divine, and under the lenses of the three Abrahamic religions, would inter alia, also be omnipotent and omniscient. In this paper, I consider the attitude of such a being to rule-consequentialism in human society. I argue, from a probabilistic perspective, that the evidence of Abrahamic scripture confirms, to a degree, that God (...) would judge rule-consequentialism to be a sound moral theory in different societies. I also consider a similar argument from a secular perspective. (shrink)

This paper defends views like rule consequentialism by distinguishing between two sorts of ideal world objections. It aims to show that one of those sorts of objections is question-begging. Its success would open up a path forward for such views.

Derek Parfit’s On What Matters endorses Kantian Contractualism, the normative theory that everyone ought to follow the rules that everyone could rationally will that everyone accept. This paper explores Parfit’s argument that Kantian Contractualism converges with Rule Consequentialism. A pivotal concept in Parfit’s argument is the concept of impartiality, which he seems to equate agent-neutrality. This paper argues that equating impartiality and agent-neutrality is insufficient, since some agent-neutral considerations are silly and some are not impartial. Perhaps more importantly, (...) there is little realistic prospect of Kantian Contractualism converging with Rule Consequentialism unless the same impartial reasons drive rule selection in the two theories. (shrink)

Derek Parfit argues that everyone ought to follow the principles whose universal acceptance would make things go best. I present a counterexample: a world in which no one's moral beliefs have any motivating force. I explain how Parfit's metaethical commitments imply that such a world is possible, and why this possibility is a problem for Parfit's project of reconciling Kantianism, contractualism, and consequentialism. I consider two of Parfit's responses to my counterexample.

This paper develops an argument that, if rule consequentialism is true, it’s not possible to defend it as the outcome of reflective equilibrium. Ordinary agents like you and me are ignorant of too many empirical facts. Our ignorance is a defeater for our moral intuitions. Even worse, there aren’t enough undefeated intuitions left to defend rule consequentialism. The problem I’ll describe won’t be specific to rule consequentialists, but it will be especially sharp for them.

We argue that there is a tension between two monistic claims that are the core of recent work in epistemic consequentialism. The first is a form of monism about epistemic value, commonly known as veritism: accuracy is the sole final objective to be promoted in the epistemic domain. The other is a form of monism about a class of epistemic scoring rules: that is, strictly proper scoring rules are the only legitimate measures of inaccuracy. These two monisms, we argue, (...) are in tension with each other. If only accuracy has final epistemic value, then there are legitimate alternatives to strictly proper scoring rules. Our argument relies on the way scoring rules are used in contexts where accuracy is rewarded, such as education. (shrink)

I explore the debate about whether consequentialist theories can adequately accommodate the moral force of promissory obligation. I outline a straightforward act consequentialist account grounded in the value of satisfying expectations, and raise and assess three objections to this account: that it counterintuitively predicts that certain promises should be broken when commonsense morality insists that they should be kept, that the account is circular, and Michael Cholbi’s argument that this account problematically implies that promise-making is frequently obligatory. I then discuss (...) alternative act consequentialist accounts, including Philip Pettit’s suggestion that promise-keeping is an intrinsic good and Michael Smith’s agent-relative account. I outline Brad Hooker’s rule consequentialist account of promissory obligation and raise a challenge for it. I conclude that appeals to intuitions about cases will not settle the dispute, and that consequentialists and their critics must instead engage in substantive debate about the nature and stringency of promissory obligation. (shrink)

Consequentialist theories often neglect reasons for action. They offer theories of the rightness or the goodness of actions, or of virtue, but they typically do not include theories of reasons. However, consequentialists can give plausible accounts of reasons. This chapter examines some different ways in which such accounts might be developed, focusing on Act Consequentialism and Rule Consequentialism and on the relationship between reasons and rightness. It notes that adding claims about reasons to consequentialist theories may introduce (...) a welcome kind of complexity, and in doing so may help to make consequentialist approaches to ethics more appealing. For example, it may help consequentialists to explain the ideas of moral constraints and moral options. (shrink)

Normative moral theories are frequently invoked to serve one of two distinct purposes: (1) explicate a criterion of rightness, or (2) provide an ethical decision-making procedure. Although a criterion of rightness provides a valuable theoretical ideal, proposed criteria rarely can be (nor are they intended to be) directly translated into a feasible decision-making procedure. This paper applies the computational framework of bounded rationality to moral decision-making to ask: how ought a bounded human agent make ethical decisions? We suggest agents ought (...) to follow moral maxims: principles that approximate rightness in many situations, but that can be overridden in specific, precisely describable circumstances. While this intuitive idea has been proposed many times before, we provide a precise model of how maxim consequentialism functions as an approximation to an act-consequentialist criterion of rightness, while maintaining the flexibility and defeasibility that has eluded most forms of rule consequentialism. Furthermore, while our overarching aim is to propose a new normative standard of moral decision-making, we demonstrate how maxim consequentialism can also function as a descriptive account of human behavior. We conclude by noting that different criteria of rightness may lead to different maxim-based ethics. (shrink)

Following Shelly Kagan’s useful terminology, foundational consequentialists are those who hold that the ranking of outcomes is at the foundation of all moral assessment. That is, they hold that moral assessments of right and wrong, virtuous and vicious, morally good and morally bad, etc. are all ultimately a function of how outcomes rank. But foundational consequentialists disagree on what is to be directly evaluated in terms of the ranking of outcomes, which is to say that they disagree on what the (...) primary evaluative focal point is. Act-consequentialists take acts to be the primary evaluative focal point. They evaluate acts in terms of how their outcomes rank (the higher ranked the outcome, the morally better the act), but evaluate everything else in terms of the morally best acts. Thus, the morally best rules are those that would, if internalized, most reliably lead us to perform the morally best acts. Rule-consequentialists, by contrast, take rules to be the primary evaluative focal point. They evaluate rules according to how their outcomes rank and then assess everything else in terms of the morally best rules. Thus, the morally best acts are those that conform to the morally best rules. In this paper, I argue that foundational consequentialists should not take the primary evaluative focal point (or points) to be acts, rules, virtues, or even everything. In so doing, I argue against act-consequentialism, rule-consequentialism, and global consequentialism. But my project is not entirely negative, for I argue that the primary evaluative focal point should be a complex of acts and attitudes. In the end, then, I claim that foundational consequentialists should accept a new kind of consequentialism, which I call attitude-consequentialism. (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.

In ‘Measuring the Consequences of Rules’, Holly Smith presents two problems involving the indeterminacy of compliance, which she takes to be fatal for all forms of rule-utilitarianism. In this reply, I attempt to dispel both problems.

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. (shrink)

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. (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)

Deontic constraints prohibit an agent performing acts of a certain type even when doing so will prevent more instances of that act being performed by others. In this article I show how deontic constraints can be interpreted as either maximizing or non-maximizing rules. I then argue that they should be interpreted as maximizing rules because interpreting them as non-maximizing rules results in a problem with moral advice. Given this conclusion, a strong case can be made that consequentialism provides the (...) best account of deontic constraints. (shrink)

James Rule is puzzled by the ‘idiosyncratic’ approach that I take to the philosophical study of privacy. As evidence for this idiosyncracy, he cites my relative indifference to the distinction between consequentialist and deontological perspectives on privacy although these differences are proof of ‘intricate, yet enormously consequential intellectual tensions’. My choice of philosophical topics is ‘unsystematic’ and more a reflection of my own ‘intellectual hobby-horses’ than a ‘well-worked-out view of what students most need to know’. Finally, Rule concludes, (...) because ‘the most important privacy questions are excruciating’, we need ‘more systematic guidance than is provided here’. I am grateful to the editors for the chance to respond to these complaints. (shrink)

This paper argues that influential Mahāyāna ethicists, such as Śāntideva, who allow for moral rules to be proscribed under the expediency of a compassionate aim, seriously compromise the very notion of moral responsibility. The central thesis is that moral responsibility is intelligible only in relation to conceptions of freedom and human dignity that reflect a participation in, and sharing of, interpersonal relationships. The central thesis of the paper is that revisionary strategies, which seek to explain agency in event-causal terms, set (...) the stage for moral epiphenomenalism. On the view I defend here, an effective compatibilist solution to the problem of reconciling freedom of the will and determinism depends on expanding, rather than eliminating, the complex register of factors that underpin the experiential aspects of our moral life.

The U.S. election in November 2016 raised and amplified doubts about first-past-the-post (“plurality rule”) electoral systems. Arguments against plurality rule and for alternatives like preferential voting tend to be consequentialist: it is argued that systems like preferential voting produce different, better outcomes. After briefly noting why the consequentialist case against plurality rule is more complex and contentious than it first appears, I offer an expressive alternative: plurality rule produces actual or apparent dilemmas for voters in ways (...) that are morally objectionable, and avoidable under preferential voting systems. This expressive case against plurality rule is both simpler and more ecumenical than its consequentialist counterpart, and it provides strong reasons to prefer alternatives to plurality rule. Moreover, it suggests a distinct way of evaluating different alternatives like preferential voting. (shrink)

In his seminal essay, 'Two Concepts of Rules', John Rawls draws a central distinction between justifying a practice and justifying a particular action falling under it. In this review, Leslie Allan walks through Rawls's essay, highlighting his key arguments for a strengthened version of rule utilitarianism and reflecting on the lasting influence of his analysis.

This paper starts by juxtaposing the normative ethics in the final part of Parfit's final book, On What Matters, vol. 3, with the normative ethics in his earlier books, Reasons and Persons and On What Matters, vol. 1. The paper then addresses three questions. The first is, where does the reflective-equilibrium methodology that Parfit endorsed in the first volume of On What Matters lead? The second is, is the Act-involving Act Consequentialism that Parfit considers in the final volume of (...) On What Matters as plausible as Rossian deontology? The third is, how is the new argument that Parfit puts forward for Rule Consequentialism supposed to work? (shrink)

This paper draws on the 'Fitting Attitudes' analysis of value to argue that we should take the concept of fittingness (rather than value) as our normative primitive. I will argue that the fittingness framework enhances the clarity and expressive power of our normative theorising. Along the way, we will see how the fittingness framework illuminates our understanding of various moral theories, and why it casts doubt on the Global Consequentialist idea that acts and (say) eye colours are normatively on a (...) par. We will see why even consequentialists, in taking rightness to be in some sense determined by goodness, should not think that rightness is conceptually reducible to goodness. Finally, I will use the fittingness framework to explicate the distinction between consequentialist and deontological theories, with particular attention to the contentious case of Rule Consequentialism.

The article is a plea for ethicists to regard probability as one of their most important concerns. It outlines a series of topics of central importance in ethical theory in which probability is implicated, often in a surprisingly deep way, and lists a number of open problems. Topics covered include: interpretations of probability in ethical contexts; the evaluative and normative significance of risk or uncertainty; uses and abuses of expected utility theory; veils of ignorance; Harsanyi’s aggregation theorem; population size problems; (...) equality; fairness; giving priority to the worse off; continuity; incommensurability; nonexpected utility theory; evaluative measurement; aggregation; causal and evidential decision theory; act consequentialism; rule consequentialism; and deontology.

I introduce a new formulation of rule consequentialism, defended as an improvement on traditional formulations. My new formulation cleanly avoids what Parfit calls “ideal world” objections. I suggest that those objections arise because traditional formulations incorporate counterfactual comparisons about how things could go differently. My new formulation eliminates those counterfactual comparisons. Part of the interest of the new formulation is as a model of how to reformulate structurally similar views, including various kinds of contractualism.

The verdicts standard consequentialism gives about what we are obligated to do crucially depend on what theory of value the consequentialist accepts. This makes it hard to say what separates standard consequentialist theories from non-consequentialist theories. This article discusses how we can draw sharp lines separating standard consequentialist theories from other theories and what assumptions about goodness we must make in order to draw these lines. The discussion touches on cases of deontic constraints, cases of deontic options, and cases (...) involved in the so-called "actualism"/"possibilism" debate. What emerges is that there are various interesting patterns relating the different commitments of consequentialism, different principles about obligation and about goodness, and different rules concerning how facts about values determine facts about obligation.

Many morally significant outcomes can be brought about only if several individuals contribute to them. However, individual contributions to collective outcomes often fail to have morally significant effects on their own. Some have concluded from this that it is permissible to do nothing. What I call ‘the problem of insignificant hands’ is the challenge of determining whether and when people are obligated to contribute. For this to be the case, I argue, the prospect of helping to bring about the outcome (...) has to be good enough. Furthermore, the individual must be in a position to increase the probability of its being brought about to an appropriate extent. Finally, I argue that when too few are willing to contribute, people may have a duty to increase their number. Thus, someone can be obligated to contribute or to get others to contribute. This prospect account is consistent with Kantianism, contractualism and rule consequentialism but inconsistent with act consequentialism. (shrink)

Pattern-based reasons are reasons for action deriving not from the features of our own actions, but from the features of the larger patterns of action in which we might be participating. These reasons might relate to the patterns of action that will actually be carried out, or they might relate to merely hypothetical patterns. In past work, I have argued that accepting merely hypothetical pattern-based reasons, together with a plausible account of how to weigh these reasons, can lead to disastrous (...) consequences. However, in this article, I argue that this problem is not limited to hypothetical pattern-based reasons: it turns out that there are analogous issues for reasons deriving from actual patterns. I then suggest that we can avoid this problem by adopting a different account of the weight of pattern-based reasons. (shrink)

Some right acts have what philosophers call moral worth. A right act has moral worth if and only if its agent deserves credit for having acted rightly in this instance. And I argue that an agent deserves credit for having acted rightly if and only if her act issues from an appropriate set of concerns, where the appropriateness of these concerns is a function what her ultimate moral concerns should be. Two important upshots of the resulting account of moral worth (...) are that (1) an act can have moral worth even if it doesn’t manifest a concern for doing what’s right and that (2) an act can lack moral worth even if it is performed for the right reasons.

A powerful objection against moral conventionalism says that it gives the wrong reasons for individual rights and duties. The reason why I must not break my promise to you, for example, should lie in the damage to you—rather than to the practice of promising or to all other participants in that practice. Common targets of this objection include the theories of Hobbes, Gauthier, Hooker, Binmore, and Rawls. I argue that the conventionalism of these theories is superficial; genuinely conventionalist theories are (...) not vulnerable to the objection; and genuine moral conventionalism is independently plausible.

This is an introduction to an edited volume of critical reactions to Derek Parfit's book On What Matters. It outlines Parfit's key ideas on reasons and rationality, his revisionary interpretations of Kantian ethics, his versions of Kantian Contractualism and Rule Consequentialism, and his master argument that attempts to show how the best versions of these ethical theories converge. The introduction also intoruces the essays of the volume.

The chapter juxtaposes the fairly quick and automatic thinking and decision making that constitutes everyday moral thought and action with the slower, more complicated, and more reflective thinking that steps beyond everyday moral thought. Various difficulties that can slow down everyday moral thought are catalogued in this paper. The paper explains how dealing with many of these difficulties leads to thinking about moral principles. And, even where there are not such difficulties, everyday moral thought can be challenged by repeated “why?” (...) questions. Pushed far enough, such questions have to be answered by admitting ignorance or by pointing to theses about whatever ultimately makes acts morally required, permissible, or prohibited. Such theses are moral theories. As a point about moral theories, the paper ends by pointing out a respect in which everyday moral thought is more like rule-consequentialism, contractualism, foundational pluralism, and virtue ethics than everyday moral thought is like traditional act-consequentialism.

Why should moral philosophers, moral psychologists, and machine ethicists care about computational complexity? Debates on whether artificial intelligence (AI) can or should be used to solve problems in ethical domains have mainly been driven by what AI can or cannot do in terms of human capacities. In this paper, we tackle the problem from the other end by exploring what kind of moral machines are possible based on what computational systems can or cannot do. To do so, we analyze normative (...) ethics through the lens of computational complexity. First, we introduce computational complexity for the uninitiated reader and discuss how the complexity of ethical problems can be framed within Marr’s three levels of analysis. We then study a range of ethical problems based on consequentialism, deontology, and virtue ethics, with the aim of elucidating the complexity associated with the problems themselves (e.g., due to combinatorics, uncertainty, strategic dynamics), the computational methods employed (e.g., probability, logic, learning), and the available resources (e.g., time, knowledge, learning). The results indicate that most problems the normative frameworks pose lead to tractability issues in every category analyzed. Our investigation also provides several insights about the computational nature of normative ethics, including the differences between rule- and outcome-based moral strategies, and the implementation-variance with regard to moral resources. We then discuss the consequences complexity results have for the prospect of moral machines in virtue of the trade-off between optimality and efficiency. Finally, we elucidate how computational complexity can be used to inform both philosophical and cognitive-psychological research on human morality by advancing the moral tractability thesis.

A dialogue, in three parts, on utilitarian vulnerability to exploitation.

Abstract Tom Dougherty observes that challenges to counting the numbers often cite John Taurek’s 1977 article, “Should the Numbers Count.” Dougherty, though sympathetic to Taurek’s (and others) critique of consequentialism’s aggregating good across individuals, defends a non-consequentialist principle for addition he calls “the Ends Principle. Take the case (he labels “Drug”) when an agent, possessing a dose of a lifesaving drug, can save one person with the entire dose, or two people, each of whom only need half the dose. (...) Dougherty argues that a rational agent, summing her altruistic goals (three), but unable to save all three, will save two. I give two criticisms of Dougherty’s paper. (1) He hasn’t ruled out, though acknowledging, the equal chance principle as deontological grounds for deciding Drug. (2) An agent using the Ends Principle in Drug, as he formulates it, will not have the requisite aims to make use of the Principle. I also consider an issue, little discussed, the conditions for aggregation in general. (shrink)

Uniformity in human actions and attitudes incumbent with the ceteris paribus clause of folk psychology lucidly transits moral thoughts into the domain of subject versus object-centric explorations. In Zettel, Wittgenstein argues, “Concepts with fixed limits would demand uniformity of behaviour, but where I am certain, someone else is uncertain. And that is the fact of nature.” (Wittgenstein 2007, 68). Reflecting on the moral principle of “ethical giving” revives a novel stance in modern moral philosophy. An “ethical giving” is a moral (...) position that looks at giving from the context of harmonizing the changing demands of situations with normative ethical principles. Despite giving more prominence to the query of intuition, the chapter brings up the justification of normative moral principles pertaining to their applications and purports. Human activities aimed at decision-making goals conducted by the moral compass are nothing but the sanction of certain ethical norms and rules. In this context, two principles, the normative aspect and the perspective aspect need to be expounded in parallel. (shrink)

A traditional idea is that moral judgment involves more than calculating the consequences of actions; it also requires an assessment of the agent's intentions, the act's nature, and whether the agent uses another person as a means to her ends. I survey experimental developments suggesting that ordinary people often tacitly reason in terms of such deontological rules. It's now unclear whether we should posit a traditional form of the doctrine of double effect. However, further research suggests that a range of (...) non-consequentialist factors influence moral judgment, including intentions, commissions, personal harm, and agent-centered commitments. Many, if not all, such factors appear to affect how involved the agent is in bringing about an outcome. (shrink)

I argue that Alvin Goldman has failed to save process reliabilism from my critique in earlier work of consequentialist or teleological epistemic theories. First, Goldman misconstrues the nature of my challenge: two of the cases he discusses I never claimed to be counterexamples to process reliabilism. Second, Goldman’s reply to the type of case I actually claimed to be a counterexample to process reliabilism is unsuccessful. He proposes a variety of responses, but all of them either feature an implausible restriction (...) on process types, or fail to rule out cases with the sort of structure that generates the worry, or both.

The two purposes of this essay. The general philosophical problem with most versions of social libertarianism and how this essay will proceed. The specific problem with liberty explained by a thought-experiment. The positive and abstract theory of interpersonal liberty-in-itself as ‘the absence of interpersonal initiated constraints on want-satisfaction’, for short ‘no initiated impositions’. The individualistic liberty-maximisation theory solves the problems of clashes, defences, and rectifications without entailing interpersonal utility comparisons or libertarian consequentialism. The practical implications of instantiating liberty: three (...) rules of liberty-in-practice, 1) initial ultimate control of one’s body, 2) initial ultimate control of one’s used resources, 3) consensual interpersonal interactions and resource transfers. These rules are economically efficient and maximise general want-satisfaction. Private property and legal remedies are additional practical institutional aspects, but to which ‘initiated impositions’ then apply prima facie. Libertarian law is often mistaken for complete libertarianism. Moral explanations are a separate issue. The three main moral theories imply libertarianism, but it can be morally posited independently of them. Critical rationalism and its application. No empirical or argumentative support for theories. An important ambiguity with ‘justification’. How the epistemology applies to the theory of liberty and its application but remains separable in principle. Conclusion: there are further published explanations but this should be enough to generate useful criticism. Appendix replying to some typical comments. (shrink)

After a regime-changing war, a state often engages in lustration—condemnation and punishment of dangerous, corrupt, or culpable remnants of the previous system—e.g., de-Nazification or the more recent de-Ba’athification in Iraq. This common practice poses an important moral dilemma for liberals because even thoughtful and nuanced lustration involves condemning groups of people, instead of treating each case individually. It also raises important questions about collective agency, group treatment, and rectifying historical injustices. Liberals often oppose lustration because it denies moral individualism and (...) ignores rule of law, and their only justifications for lustration are consequentialist ones. This article suggests that lustration may not necessarily be a problem for liberals. While group treatment might be justified on grounds of convenience and pragmatism in times of transitional justice, there are also valid moral arguments consistent with moral individualism and due process for wholesale group punishment after a war. This article offers four overlapping moral justifications, in a robust defense of the core concept of lustration that is covered by each argument. (shrink)

Some of the most interesting recent work in formal epistemology has focused on developing accuracy-based approaches to justifying Bayesian norms. These approaches are interesting not only because they offer new ways to justify these norms, but because they potentially offer a way to justify all of these norms by appeal to a single, attractive epistemic goal: having accurate beliefs. Recently, Easwaran & Fitelson (2012) have raised worries regarding whether such “all-accuracy” or “purely alethic” approaches can accommodate and justify evidential Bayesian (...) norms. In response, proponents of purely alethic approaches, such as Pettigrew (2013b) and Joyce (2016), have argued that scoring rule arguments provide us with compatible and purely alethic justifications for the traditional Bayesian norms, including evidential norms. In this paper I raise several challenges to this claim. First, I argue that many of the justifications these scoring rule arguments provide are not compatible. Second, I raise worries for the claim that these scoring rule arguments provide purely alethic justifications. Third, I turn to assess the more general question of whether purely alethic justifications for evidential norms are even possible, and argue that, without making some contentious assumptions, they are not. Fourth, I raise some further worries for the possibility of providing purely alethic justifications for content-sensitive evidential norms, like the Principal Principle. (shrink)
