The problem of insignificant hands

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.

Parfit’s Final Arguments in Normative Ethics

This paper starts by juxtaposing the normative ethics in the final part of Parfit’s final book, On What Matters, volume iii (2017), with the normative ethics in his earlier books, Reasons and Persons (1984) and On What Matters, volume i (2011). 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?

Parfit on Act Consequentialism

In the first two volumes of On What Matters, Derek Parfit argues that three major normative theories—Kantianism, Contractualism, and Consequentialism—are, in their most defensible forms, compatible, and can be reconciled as a ‘Triple Theory’. The form of Consequentialism that Parfit argues is compatible with Kantianism and Contractualism is Rule Consequentialism. This has led many to assume that Parfit does not believe that Act Consequentialism is a defensible form of Consequentialism. We draw on personal correspondence to show that this assumption is incorrect. We then consider how, in On What Matters, volume iii, which Parfit completed shortly before his death, he seeks to narrow the differences between Act Consequentialism and the Triple Theory. One of the ways in which he does this is to suggest that Impartial Rationality may be an external rival to Morality, in much the same way as egoism is an external rival to morality. We argue that this move undermines morality, as shown by Parfit’s own example of the judgements that we may make in the case of terror bombing. We conclude that Parfit’s attempts to bridge the gap between Act Consequentialism and Triple Theory meet with only limited success.

Doing Right by Wrong

A striking contrast between Reasons and Persons and On What Matters is the vastly different attitude Parfit takes towards Act Consequentialism. Parfit’s defense of Act Consequentialism against a battery of criticisms in Reasons and Persons was legendary. In On What Matters, however, Parfit remarks that Sidgwick’s act-consequentialist principle of rational benevolence is best regarded, like egoism, as an ‘external rival to morality’. What lies behind this remarkable change in attitude, if not in view, is Parfit’s focus in On What Matters on deontic moral concepts, like wrongness, and their relation to accountability and reactive attitudes like moral blame. This essay explores the details of Parfit’s later views, arguing that he did not go far enough in pursuing this line of thought and that doing so is necessary to bring out the distinctive normativity of deontic moral concepts. Parfit’s claim that the ‘ordinary’ concept of wrongness is indefinable threatens to rob the concept of normativity in the ‘reason-involving sense’. If, however, we understand wrongness in terms of there being reason to blame, lacking excuse, we can account for its distinctive normative contours.

The Rule Worship and Idealization Objections Revisited and Resisted

There are two familiar and important challenges to the rule consequentialist picture, Smart’s “rule worship objection” and the “idealization objection.” This chapter defends rule consequentialism (RC) against these challenges. It argues that to satisfactorily meet the rule worship objection, we need to reconceptualize RC. We need to think of it as not fundamentally a rival to act consequentialism or deontology or virtue theory. Instead, it can potentially adjudicate among these views. It is best viewed as a “second-order” theory that rests on a view about the nature and point of morality. The rule worship objection can be answered if we interpret RC in this way. The idealization objection can seem more difficult because it appears to arise from the basic RC approach to evaluating rules. This chapter suggests, however, that the idealization objection boils down to a familiar problem about conflicts of pro tanto duties. RC can handle it in the way that it handles such conflict.

Act Consequentialism and the No-Difference Challenge

According to act-consequentialism, only actions that make a difference to an outcome can be morally bad. Yet, there are classes of actions that don’t make a difference, but nevertheless seem to be morally bad. Explaining how such non-difference making actions are morally bad presents a challenge for act-consequentialism: the no-difference challenge. In this chapter we go into detail on what the no-difference challenge is, focusing in particular on act consequentialism. We talk about how different theories of causation affect the no-difference challenge; how the challenge shows up in real-world cases, including voting, global labor injustice, global poverty, and climate change; and we work through a number of the solutions to the challenge that have been offered, arguing that many fail to actually meet it. We defend and extend one solution that does, and we present a further solution of our own.

Supererogation and Consequentialism

The thought that acts of supererogation exist presents a challenge to all normative ethical theories. This chapter will provide an overview of the consequentialist responses to this challenge. I will begin by explaining the problem that supererogation presents for consequentialism. I will then explore consequentialist attempts to deny the existence of acts of supererogation. Next, I will examine a range of act consequentialist attempts to accommodate supererogation, including satisficing consequentialism, dual-ranking act consequentialism, and an anti-rationalist form of consequentialism. Finally, I will explore how indirect consequentialists have responded to this problem. Throughout the chapter, I will argue that in responding to the challenge of supererogation, consequentialists must choose between a more theoretically satisfying version of consequentialism and a form of consequentialism that is better able to accommodate our everyday moral intuitions and concepts.

Conflicts and Cooperation in Act Consequentialism

There are circumstances—involving conjunctive acts at a time or over time or the conjunction of acts of different agents—that threaten act consequentialism with self-defeat. There are also variants of act consequentialism—including consequentialist generalization, generalized act consequentialism, multiple-act consequentialism, cooperative consequentialism, and modally robust act consequentialism—that promise a more plausible treatment of circumstances in which cooperation is important than traditional act consequentialism. Links among these issues are explored. Attention to the nature of the normative conflicts occasioned by consequentialist assessment of actions can help reveal an important and useful variety of forms of, and resources for, act consequentialism. Its structure is not as simple as it may initially seem.

Consequentialism, Ignorance, and Uncertainty

Act consequentialism provides an answer to the question of what one ought to do, no matter which situation one is in. The problem, however, is that this answer is rarely if ever known by the agent herself. Ordinary agents do not know all the consequences of their actions, nor do they know how to assess all possible consequences. This lack of both empirical and evaluative knowledge means that ordinary agents often, or always, do not know what act consequentialism tells them to do. This “ignorance challenge,” as we might call it, is often seen as one of the main challenges for act consequentialism. This chapter discusses the main responses to this challenge. It also asks whether this challenge is unique to consequentialism.

Global Consequentialism

Many types of things are arguably appropriate objects of deontic moral assessment: not only acts but also decision procedures, character traits, motives, public moral codes, and so on. Global consequentialism recommends, for every type that is an appropriate object of deontic assessment at all, that we assess items of that type in terms of their consequences. This (and not simple act consequentialism alone) seems to be roughly the kind of consequentialist thesis that real-life consequentialists, both past and present, have generally been sympathetic to. In this chapter, I articulate a thesis along these lines and defend the thesis in question against the most common objection it faces (“the inconsistency objection”). I discuss the extent to which “going global” deals satisfactorily with three standard objections to act consequentialism: the incorrect verdicts objection, the self-defeatingness objection, and the silence objection. I conclude that global consequentialism has adequate responses to all of these objections, but that it is unclear whether global consequentialism is superior to an account that simply stresses the importance of global axiological assessment.
