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.

It is a challenge to explain how evolutionary altruism can evolve by the process of natural selection, since altruists in a group will be less fit than the selfish individuals in the same group who receive benefits but do not make donations of their own. Darwin proposed a theory of group selection to solve this puzzle. Very simply, even though altruists are less fit than selfish individuals within any single group, groups of altruists are more fit than groups of selfish (...) individuals. If a population is subdivided into many groups that vary in their altruistic tendencies, altruism will be favored at the level of selection among groups even as it is being disfavored at the level of selection among individuals within groups. Darwin’s scenario became the basis for a theoretical framework called multilevel selection theory. (shrink)

This article is an attempt to defend Scanlon's contractualism against the so-called aggregation problems. Scanlon's contractualism attempts to make sense of right and wrong in terms of principles which no one could reasonably reject. These principles are a function of what kind personal objections persons can make to alternative sets of moral principles. Because of this, it has been argued that contractualism is unable to account for how groups of different sizes are to be treated. In this article, I argue (...) that contactualism, even if with its focus on personal burdens, can come to plausible conclusions in the group cases. (shrink)

This article provides a critical introduction to contractualism as a moral or ethical theory, that is, as a theory of the rightness and wrongness of individual conduct – focusing specifically on the influential 'Kantian' version of contractualism due to T. M. Scanlon. I begin by elucidating the key features of Scanlon's contractualism: justifiability to others; reasonable rejectability; the individualist restriction; and mutual recognition. I then turn to discuss both its appeal and the main objections that have been raised to it (...) – objections concerning our duties to the cognitively limited and impaired, aggregation, demandingness, normativity and explanatory adequacy. I conclude by mentioning some contractualist alternatives to Scanlon's theory. (shrink)

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

I am pleased by the degree of agreement about reasons between the three of us, which is much greater than I might have guessed. I have no objection whatever to the project of giving the kind of psychological description of deliberation about reasons that Gibbard proposes. I agree that “weighing X in favor of A isn’t mysterious,” but I do confess to some doubt about how a psychological description of this process of weighing “explains, indirectly, X’s counting in favor of (...) A in such circumstances.” If there is any disagreement between Gibbard and me on this point, I think it is over the degree to which such an explanation is to be expected. (shrink)

The central thesis of Derek Parfit's On What Matters is that three of the most important secular moral traditions – Kantianism, contractualism, and consequentialism – all actually converge in a way onto the same view. It is in this sense that he suggests that we may all be 'climbing the same mountain, but from different sides'. In this paper, I argue that Parfit's argument that we are all metaphorically climbing the same mountain is unsound. One reason his argument does not (...) work is that he has misunderstood the way in which a plausible rule-consequentialism should understand the supervenience of rightness on all possible acceptance levels of the ideal moral code. In place of Parfit's own understanding of this, I develop a view I call 'variable-rate rule-utilitarianism', which I argue shares the key insight of Parfit's view but avoids a fatal objection to his own articulation of that insight. Finally, I explore how this modification might allow us to still make a case that we are all 'climbing the same mountain', albeit in a very different way and for very different reasons than the ones Parfit had in mind.

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)

sonable, in this sense, if we ignore, or give too little weight to, some other people's well-being or moral claims.' Some critics have suggested that, because Scanlon appeals to this sense of 'reasonable', his formula is empty. On this objection, whenever we believe that some act is wrong, we shall believe that people have moral claims not to be treated in this way. We could therefore argue that such acts are disallowed by some principle which no one could reasonably reject, (...) since anyone who rejected this principle would be giving too little weight to people's moral claims not to be treated in this way. Since everyone could claim that the principles which they accept could not be reasonably rejected, Scanlon's Formula would make no difference to our moral thinking. That is not so. If we reject the principles that disallow certain acts, we are denying that such acts are wrong. This denial would be unreasonable if it would give too little weight to some other people's moral claims. So Scanlon's Formula implies that.. (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)

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.

Contractualist moral theories are often criticized on the grounds that they have counterintuitive implications for moral status. In this paper I attempt to provide a comprehensive answer to the question: What forms of contractualism face this problem, and how serious is the problem? To do this I develop a classification of different kinds of contractualist theory, based on philosophical motivation.

Richard Brandt is one of the most eminent and influential of contemporary moral philosophers. His work has been concerned with how to justify what is good or right not by reliance on intuitions or theories about what moral words mean but by the explanation of moral psychology and the description of what it is to value something, or to think it immoral. His approach thus stands in marked contrast to the influential theories of John Rawls. The essays reprinted in this (...) collection span a period of almost 30 years and include many classic pieces in metaethical and normative ethical theory. The collection is aimed at both those moral philosophers familiar with Brandt's work and at those philosophers who may be largely unfamiliar with his work. The latter group will be struck by the lucid unpretentious style and the cumulative weight of Brandt's contributions to topics that remain at the forefront of moral philosophy. (shrink)

What system of morals should rational people select as the best for society? Using a contemporary psychological theory of action and of motivation, Richard Brandt's Oxford lectures argue that the purpose of living should be to strive for the greatest good for the largest number of people. Brandt's discussions range from the concept of welfare to conflict between utilitarian moral codes and the dictates of self-interest.

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.

Despite wide acceptance that the attributes of living creatures have appeared through a cumulative evolutionary process guided chiefly by natural selection, many human activities have seemed analytically inaccessible through such an approach. Prominent evolutionary biologists, for example, have described morality as contrary to the direction of biological evolution, and moral philosophers rarely regard evolution as relevant to their discussions. -/- The Biology of Moral Systems adopts the position that moral questions arise out of conflicts of interest, and that moral systems (...) are ways of using confluences of interest at lower levels of social organiation to deal with conflicts of interest at higher levels. Moral systems are described as systems of indirect reciprocity: humans gain and lose socially and reproductively not only by direct transactions, but also by the reputations they gain from the everyday flow of social interactions. -/- The author develops a general theory of human interests, using senescence and effort theory from biology, to help analye the patterning of human lifetimes. He argues that the ultimate interests of humans are reproductive, and that the concept of morality has arisen within groups because of its contribution to unity in the context, ultimately, of success in intergroup competition. He contends that morality is not easily relatable to universals, and he carries this argument into a discussion of what he calls the greatest of all moral problems, the nuclear arms race. (shrink)
