In his interesting and provocative article ‘Being Good in a World of Need’, Larry Temkin argues for the possibility of a type of Each-We Dilemma in which, if we each produce the most good we can individually, we produce a worse outcome collectively. Such situations would ostensibly be troubling from the standpoint of effective altruism, the project of finding out how to do the most good and doing it, subject to not violating side-constraints. We here show that Temkin’s argument is (...) more controversial than it may appear initially regarding both impartiality and goodness. This is because it is both inconsistent with (i) a plausible conception of impartiality (Anonymity) and inconsistent with (ii) the standard view of goodness (the Internal Aspects View). Moreover, because (i) and (ii) are entailed by the sense of ‘impartial goodness’ that effective altruism tentatively adopts, Temkin’s argument is less relevant to effective altruism than he suggests.

Many prominent ethicists, including Shelly Kagan, John Rawls, and Thomas Scanlon, accept a kind of epistemic modesty thesis concerning our capacity to carry out the project of ethical theorizing. But it is a thesis that has received surprisingly little explicit and focused attention, despite its widespread acceptance. After explaining why the thesis is true, I argue that it has several implications in metaethics, including, especially, implications that should lead us to rethink our understanding of Reductive Realism. In particular, the thesis (...) of epistemic modesty in ethics implies a kind of epistemic modesty about the metaphysical nature of ethics, if Reductive Realism about the metaphysical nature of ethics is true, and it implies that normative concepts are indispensable to practical deliberation in a way that answers an influential objection to Reductive Realism from Jonathan Dancy, David Enoch, William FitzPatrick, and Derek Parfit.

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.

The purpose of this paper is to show how some of the controversial questions concerning utilitarianism can be clarified by the modelling techniques and the other analytical tools of decision theory (and, sometimes, of game theory). It is suggested that the moral rules of utilitarian ethics have a logical status similar to that of the normative rules (theorems) of such formal normative disciplines as decision theory and game theory.The paper argues that social utility should be defined, not in hedonistic or (...) in ideal-utilitarian terms, but rather in terms of individual preferences, in accordance with the author's equiprobability model of moral value judgments.

Resumo: Joseph Raz tornou-se bastante conhecido pelo conceito de razões excludentes, que ele aplicou na análise de uma série de conceitos práticos, como decisões, regras e obrigações. No entanto, a literatura especializada exibe um alto grau de ceticismo quanto à existência de razões excludentes, e até sobre a coerência do conceito. Ao longo de sua obra, Raz sempre focou em duas espécies de razões excludentes: as diretamente motivacionais e as evidenciais. Atribui-se a isso o fato de o conceito ter recebido (...) tantas críticas. Neste artigo, dá-se destaque a uma outra categoria de razões excludentes, negligenciada por Raz: as razões que são excluídas por sua própria natureza. Argumenta-se aqui que essa categoria é capaz de mostrar, não apenas que o conceito não é vazio ou inconsistente, mas também que ele tem um papel importante a desempenhar na elucidação de um importante domínio da moralidade: o domínio das relações afetivas.

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)

In his article “Utility Cascades”, Max Khan Hayward argues that act-utilitarians should sometimes either ignore evidence about the effectiveness of their actions or fail to apportion their support to an action's effectiveness. His conclusions are said to have particular significance for the effective altruism movement, which centers seeking and being guided by evidence. Hayward's argument is that act-utilitarians are vulnerable to succumbing to “utility cascades”, that these cascades function to frustrate the ultimate goals of act-utilitarians, and that one apposite way (...) to avoid them is by “ostriching”: ignoring relevant evidence. If true, this conclusion would have remarkable consequences for act-utilitarianism and the effective altruism movement. However, Hayward is mistaken – albeit in an interesting way and with broader significance for moral philosophy. His argument trades on a subtle mischaracterization of act-utilitarianism. Act-utilitarians are not especially vulnerable to utility cascades, and they shouldn't ostrich. (shrink)

It is tempting to think (1) that we may sometimes have hopelessly utopian duties and yet (2) that “ought” implies “can.” How might we square these apparently conflicting claims? A simple solution is to interpret hopelessly utopian duties as duties to "pursue" the achievement of manifestly unattainable outcomes (as opposed to duties to "achieve" the outcomes), thereby promising to vindicate the possibility of such duties in a way that is compatible with “ought” implies “can.” The main challenge for this simple (...) solution is to say what the relevant “duties to pursue” are supposed to involve. We survey several existing candidates (duties to try, duties to approximate, duties to do our part, and dynamic duties) and argue that none of them succeeds in delivering on the promise of the simple solution. We then propose a previously untheorized class of duties that we call "duties to devote ourselves" to achieving an outcome, and argue that such duties provide us with an interpretation of hopelessly utopian duties that is up to the task.

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.

Effective altruism (EA) is a movement devoted to the idea of doing good in the most effective way possible. EA has been the target of a number of critiques. In this article, I focus on one prominent critique: that EA fails to acknowledge the importance of institutional change. One version of this critique claims that EA relies on an overly individualistic approach to ethics. Defenders of EA have objected that this charge either fails to identify a problem with EA's core (...) idea that each of us should do the most good we can, or makes unreasonable claims about what we should do. However, I argue that we can understand the critique in a way that is well motivated, and that can avoid these objections. (shrink)

We can distinguish two kinds of moral universalization tests for practical principles. One requires that the universal practice of the principle, i.e., universal conformity to it by all agents in a given world, satisfies some condition. The other requires that conformity to the principle by any possible agent, in any situation and at any time, satisfies some condition. We can call these universal practice and universal applicability tests respectively. The logical distinction between these tests is rarely appreciated, and many philosophers (...) systematically confuse them with each other. In practice, UP tests are more frequently used to defend deontological norms, while UA tests are used to defend consequentialist norms. Both conceptual argument and practical examples of their applications will show that UA tests are decisively superior to UP tests for grounding moral norms, casting greater doubt upon deontological theories which rely upon the latter unless they can reformulate their arguments using some version of a UA test.

The contrast typically made between utilitarianism and virtue theory is overdrawn. Utilitarianism is a universal emulator: it implies that we should lie, cheat, steal, even appropriate Aristotle, when that is what brings about the best outcomes. In some cases and in some worlds it is best for us to focus as precisely as possible on individual acts. In other cases and worlds it is best for us to be concerned with character traits. Global environmental change leads to concerns about character (...) because the best results will be produced by generally uncoupling my behavior from that of others. Thus, in this case and in this world, utilitarians should be virtue theorists. (shrink)

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.

Utilitarians think that what matters in ethics is making the world a better place. In that case, it might seem that we each rationally ought to do our best—perform the actions, out of those open to each of us, with the best expected outcomes. In other words, we should follow act-utilitarian reasons. But often the result of many altruistic agents following such individualistic reasons is worse than the result of them following collectivist ‘team-reasons’. So utilitarians should reject act utilitarianism, and (...) accept a dualist view according to which both individualistic and team reasons are fundamental. In order to align these distinct kinds of reason, utilitarians must focus centrally on questions of political and social reform—as did their historical forebears. (shrink)

This volume is a collation of original contributions from the key actors of a new trend in the contemporary theory of knowledge and belief, that we call “dynamic epistemology”. It brings the works of these researchers under a single umbrella by highlighting the coherence of their current themes, and by establishing connections between topics that, up until now, have been investigated independently. It also illustrates how the new analytical toolbox unveils questions about the theory of knowledge, belief, preference, action, and (...) rationality, in a number of central axes in dynamic epistemology: temporal, social, probabilistic and even deontic dynamics.

This thesis is about the moral reasons we have to do less than best. It consists of six chapters. Part I of the thesis proposes, extends, and defends reasons to do less than best. In Chapter One (“The Conditional Obligation”) I outline and reject two recent arguments from Joe Horton and Theron Pummer for the claim that we have a conditional obligation to bring about the most good. In Chapter Two (“Agglomeration and Agent-Relative Costs”) I argue that agent-relative costs can (...) justify permissions to less than best in a far greater range of decisions contexts than we currently believe. In Chapter Three (“Risk and Aggregation”) I discuss how anti-aggregative moral theories deal with risk, whilst proposing an argument in favour of ex-post moral theories. -/- In Part II of the thesis, I discuss longtermism, presenting a series of reasons to believe we have both significant permissions and obligations to prioritise those in the short-term. In Chapter Four (“Listening to Future People”) I criticise a recent argument presented by Andreas Mogensen for the claim we cannot have obligations grounded in the wellbeing of future people. I then show that, even permitting the existence of obligations to future people, we still have significant reasons to resist longtermism on the grounds of partiality. In Chapter Five (“The Complaints of Future People”) I argue that scepticism about aggregation is inconsistent with an obligation, or indeed even a permission, to help far future people. In Chapter Six (“Leaving the Present Behind”) I explore the moral significance of “dooming”, whilst arguing that we have a pro tanto reason of fairness to prioritise aiding those currently in existence.

Utility cascades occur when a utilitarian’s reduction of support for an intervention reduces the effectiveness of that intervention, leading the utilitarian to further reduce support, thereby further undermining effectiveness, and so on, in a negative spiral. This paper illustrates the mechanisms by which utility cascades occur, and then draws out the theoretical and practical implications. Theoretically, utility cascades provide an argument that the utilitarian agent should sometimes either ignore evidence about effectiveness or fail to apportion support to effectiveness. Practically, utility (...) cascades call upon utilitarians to rethink their relationship with the social movement known as Effective Altruism, which insists on the importance of seeking and being guided by evidence concerning effectiveness. This has particular implications for the ‘Institutional Critique’ of Effective Altruism, which holds that Effective Altruists undervalue political and systemic reforms. The problem of utility cascades undermines the Effective Altruist response to the Institutional Critique. (shrink)

There is a theory that one ought morally to do the best one can, when 'best' is suitably interpreted. There are also some examples in which, although every agent involved does the best she can, the group composed of them does not. Some philosophers think that these examples show the theory to be wrong. In particular, they think that such examples motivate a view which incorporates a requirement of cooperativeness in a particular way, though they disagree as to the exact (...) nature of this requirement. This paper will argue both that such views are problematic and that the examples do not motivate departure from the original theory. (shrink)

The view that what one ought, or is obligated, to do is the best that one can do faces a problem even from the perspective of someone sympathetic with the view: there are cases of group action where, through lack of cooperation, the best that can be done is not done and yet where, it seems, each individual does the best that he or she can do. In this paper, various attempts to deal with this problem are criticized and then (...) a new solution is offered, one which requires "connected" individuals to be "transigent" relative to one another concerning possible group outcomes. (shrink)

This paper works within a particular framework for reasoning about actions—sometimes known as the framework of “stit semantics”—originally due to Belnap and Perloff, based ultimately on the theory of indeterminism set out in Prior’s indeterministic tense logic, and developed in full detail by Belnap, Perloff, and Xu [3]. The issues I want to consider arise when certain normative, or decision theoretic, notions are introduced into this framework: here I will focus on the notion of a right action, and so on (...) the formulation of act utilitarianism within this indeterministic setting. The problem is simply that there are two different, and conflicting, ways of defining this notion, both well-motivated, and both carrying intuitive weight. (shrink)

Coordination games show that all individuals can do what is right according to act‐consequentialism, even if they do not bring about the best outcome as a group. This creates two problems for act‐consequentialism. First, it cannot accommodate the intuition that there is some moral failure in these cases. Second, its formulation as a criterion of rightness conflicts with the underlying act‐consequentialist concern that the best outcome is brought about. The collectivist view solves these problems by holding that any group of (...) two or more individual agents, and only individual agents, is a collective agent who itself can act rightly or wrongly. When such a collective agent does what is wrong, there is a moral failure. When all collective agents do what is right, the best outcome is brought about. In this paper, I defend the collectivist view against the No Act Objection, according to which the doings of many so called disunified collectives are not acts. (shrink)
