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.

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

Right- and wrong-making features ("moral grounds") are widely believed to play important normative roles, e.g. in morally apt or virtuous motivation. This paper argues that moral grounds have been systematically misidentified. Canonical statements of our moral theories tend to summarize, rather than directly state, the full range of moral grounds posited by the theory. Further work is required to "unpack" a theory's criterion of rightness and identify the features that are of ground-level moral significance. As a result, it is not (...) actually true that maximizing value is the relevant right-making feature even for maximizing consequentialists. Focusing on the simple example of utilitarianism, I show how careful attention to the ground level can drastically influence how we think about our moral theories. (shrink)

One of the reasons why Kantian contractualism has been seen as an appealing alternative to utilitarianism is that it seems to be able to avoid utilitarianism's extreme demandingness, while retaining a fully impartial moral point of view. I argue that in the current state of the world, contractualist obligations to help those in need are not significantly less demanding than utilitarian obligations. I also argue that while a plausible version of utilitarianism would be considerably less demanding if the state of (...) the world were different, a central aspect of contractualism means that it would remain exceedingly demanding in any practically realizable state of the world.

I argue that a right action has moral worth if and only if it is done for the right reasons - that is, for its right-making features. The reasons the agent acts on have to be identical to the reasons for which the action is right. I argue that Kantians are wrong in thinking that a right action has moral worth iff it is done because the agent thinks it is right, giving examples of morally worthy actions that are done (...) by agents who think they are wrong (Huckleberry Finn) and right actions done "because they are right" that have no moral worth. I also discuss degrees of moral worth as well as blameworthiness. (shrink)

This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

This essay begins by describing T.M. Scanlon’s contractualism according to which an action is right when it is authorised by the moral principles no one could reasonably reject. This view has argued to have implausible consequences with regards to how different-sized groups, non-human animals, and cognitively limited human beings should be treated. It has also been accused of being theoretically redundant and unable to vindicate the so-called deontic distinctions. I then distinguish between the general contractualist framework and Scanlon’s version of (...) contractualism. I explain how the general framework enables us to formulate many other versions of contractualism some of which can already be found in the literature. Understanding contractualism in this new way enables us both to understand the structural similarities and differences between different versions of contractualism and also to see the different objections to contractualism as internal debates about which version of contractualism is correct.

In this paper I argue that the best form of deontology is one understood in terms of prima facie duties. I outline how these duties are to be understood and show how they offer a plausible and elegant connection between the reason why we ought to do certain acts, the normative reasons we have to do these acts, the reason why moral agents will do them, and the reasons certain people have to resent someone who does not do them. I (...) then argue that this form of deontology makes it harder to unify a pluralistic ethics under a single consequentialist principle in a plausible way, and illustrate this with reference to Rob Shaver's consequentialist arguments.

According to Parfit, the best version of Kantian ethics takes as its central principle Kantian Contractualism: the thesis that everyone ought to follow the principles whose universal acceptance everyone could rationally will. This paper examines that thesis, identifies a class of annoying counterexamples, and suggests that when Kantian Contractualism is modified in response to these examples, the resulting principle is too complex and ad hoc to serve as the 'supreme principle of morality'.

I argue that T.M. Scanlon's contractualist account of morality has difficulty accommodating our intuitions about the moral relevance of the number of people affected by an action. I first consider the "Complaint Model" of reasonable rejection, which restricts the grounds for an individual's rejection of a principle to its effects upon herself. I argue that it can accommodate our intuitions about numbers only if we assume that, whenever we do not know who will be affected, each individual may appeal only (...) to the _expected effects on her. This assumption, I suggest, leads to counterintuitive results in cases where, although we do not know who will be affected, we do know that _someone will be. I then consider two proposals to supplement the complaint model with a direct appeal to aggregation. I argue that both are open to serious objections. (shrink)

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 basic idea of rule-utilitarianism is that right action should be defined in terms of what would be required by rules which would maximize either actual or expected utility if those rules gained general acceptance, or perhaps general compliance. Rule-utilitarians face a dilemma. They must characterize 'general acceptance' either as 100% acceptance, or as something less. On the first horn of the dilemma, rule-utilitarianism in vulnerable to the charge of utopianism; on the second, it is open to the charge of (...) arbitrariness and lack of philosophical depth. I press this objection, and develop and defend an alternative version of rule-utilitarianism which can evade the dilemma. I call this new version 'variable-rate rule-utilitarianism'. (shrink)

This essay examines the thought that our right actions have moral worth only if we perform them for the right reasons. It argues against the view, often ascribed to Kant, that morally worthy actions must be performed because they are right and argues that Kantians and others ought instead to accept the view that morally worthy actions are those performed for the reasons why they are right. In other words, morally worthy actions are those for which the reasons why they (...) were performed (the reasons motivating them) and the reasons why they morally ought to have been performed (the reasons morally justifying them) coincide. The essay calls this the Coincident Reasons Thesis and argues that it provides plausible necessary and sufficient conditions for morally worthy action, defending the claim against proposed counterexamples. It ends by showing that the plausibility of the thesis, which it argues is largely independent of any particular ethical standpoint, gives us some reason to doubt a class of ethical theories that includes utilitarianism.

What are the appropriate criteria for assessing a theory of morality? In this enlightening work, Brad Hooker begins by answering this question. He then argues for a rule-consequentialist theory which, in part, asserts that acts should be assessed morally in terms of impartially justified rules. In the end, he considers the implications of rule-consequentialism for several current controversies in practical ethics, making this clearly written, engaging book the best overall statement of this approach to ethics.

This paper examines the efforts of contractualists to develop an alternative to aggregation to govern our duty not to harm (duty to rescue) others. I conclude that many of the moral principles articulated in the literature seem to reduce to aggregation by a different name. Those that do not are viable only as long as they are limited to a handful of oddball cases at the margins of social life. If extended to run-of-the-mill conduct that accounts for virtually all unintended (...) (in the sense of undesired) harm to others—noncriminal activities that impose some risk of harm on others—they would rule out all action. Moreover, because such conduct poses an irreducible conflict between freedom of action and freedom from expected harm, it can be regulated only by principles that accept the necessity of making precisely the sorts of interpersonal trade-offs that contractualism is foundationally committed to reject: trade-offs in which the numbers count, such that a risk of serious harm to one person can be justified by small benefits to the many.

Derek Parfit presents the third volume of On What Matters, his landmark work of moral philosophy. Parfit develops further his influential treatment of reasons, normativity, the meaning of moral discourse, and the status of morality. He engages with his critics, and shows the way to resolution of their differences.

In 1982, when T. M. Scanlon published “Contractualism and Utilitarianism,” he noted that, despite the widespread attention to Rawls’ A Theory of Justice, the appeal of contractualism as a moral theory had been under appreciated. In particular, the appeal of contractualism’s account of what he then called “moral motivation” had been under appreciated.1 It seems to me that, in the intervening quarter century, despite the widespread discussion of Scanlon’s work, the appeal of contractualism, in precisely this regard, has still been (...) under appreciated—even though Scanlon makes what he once called “moral motivation” central, throughout his work. My first aim, then, is to do my best to draw out and make vivid this appeal. I will do this by first considering the two questions that Scanlon thinks must be addressed by any moral theory, what he once called “the question of subject matter” and “the question of motivation.” I will spend some time first locating and explicating the second question, of motivation, and then displaying Scanlon’s answer to it—it is this answer which provides contractualism with its under-appreciated appeal. I will then return to the question of subject matter—which will, by that point, have been revealed as not wholly distinct from the question of motivation, as Scanlon understands it. But it is as an answer to this question that Scanlon’s theory is most often.. (shrink)
