Deontologists have long been upbraided for lacking an account of justified decision- making under risk and uncertainty. One response is to develop a deontological decision theory—a set of necessary and sufficient conditions for an act’s being permissible given an agent’s imperfect information. In this article, I show that deontologists can make more use of regular decision theory than some might have thought, but that we must adapt decision theory to accommodate agent- centered options—permissions to favor or sacrifice our own interests, (...) when doing so is overall morally worse. Accommodating options requires more than just amend- ing the decision-theoretic ‘value function’. We must change the decision rule as well. (shrink)

Many scholars, including G. A. Cohen, Daniel Attas, and George Brenkert, have denied that a Kantian defense of self-ownership is possible. Kant's ostensible hostility to self-ownership can be resolved, however, upon reexamination of the Groundwork and the Metaphysics of Morals. Moreover, two novel Kantian defenses of self-ownership (narrowly construed) can be devised. The first shows that maxims of exploitation and paternalism that violate self-ownership cannot be universalized, as this leads to contradictions in conception. The second shows that physical coercion against (...) rational agents involves a profound status wrong--namely, their treatment as children or animals--and that this system of differential status and treatment (including self-ownership rights for rational agents) can be morally justified by our capacity for autonomy.

This paper takes on several distinct but related tasks. First, I present and discuss what I will call the “Ignorance Thesis,” which states that whenever an agent acts from ignorance, whether factual or moral, she is culpable for the act only if she is culpable for the ignorance from which she acts. Second, I offer a counterexample to the Ignorance Thesis, an example that applies most directly to the part I call the “Moral Ignorance Thesis.” Third, I argue for a (...) principle—Don’t Know, Don’t Kill—that supports the view that the purported counterexample actually is a counterexample. Finally, I suggest that my arguments in this direction can supply a novel sort of argument against many instances of killing and eating certain sorts of animals. (shrink)

The aim of this essay is to argue that, if a robust form of moral realism is true, then moral vagueness is ontic vagueness. The argument is by elimination: I show that neither semantic nor epistemic approaches to moral vagueness are satisfactory.

The self-ownership thesis asserts, roughly, that agents own their minds and bodies in the same way that they can own extra-personal property. One common strategy for defending the self-ownership thesis is to show that it accords with our intuitions about the wrongness of various acts involving the expropriation of body parts. We challenge this line of defense. We argue that disgust explains our resistance to these sorts of cases and present results from an original psychological experiment in support of this (...) hypothesis. We argue further that learning that disgust is responsible for pro-self-ownership intuitions should reduce our confidence in those intuitions. After considering and rejecting some prominent “debunking” arguments predicated on disgust’s evolutionary history, we provide alternative reasons for thinking that disgust is not a reliable source of moral judgments. Rejecting the reliability of disgust as a mechanism for producing moral beliefs coheres with our considered judgments about the general kinds of considerations that are morally relevant and a range of particular moral problems.

Psychologists have demonstrated the value of diversity – particularly diversity of viewpoints – for enhancing creativity, discovery, and problem solving. But one key type of viewpoint diversity is lacking in academic psychology in general and social psychology in particular: political diversity. This article reviews the available evidence and finds support for four claims: (1) Academic psychology once had considerable political diversity, but has lost nearly all of it in the last 50 years. (2) This lack of political diversity can undermine (...) the validity of social psychological science via mechanisms such as the embedding of liberal values into research questions and methods, steering researchers away from important but politically unpalatable research topics, and producing conclusions that mischaracterize liberals and conservatives alike. (3) Increased political diversity would improve social psychological science by reducing the impact of bias mechanisms such as confirmation bias, and by empowering dissenting minorities to improve the quality of the majority's thinking. (4) The underrepresentation of non-liberals in social psychology is most likely due to a combination of self-selection, hostile climate, and discrimination. We close with recommendations for increasing political diversity in social psychology. (shrink)

You are morally permitted to save your friend at the expense of a few strangers, but not at the expense of very many. However, there seems no number of strangers that marks a precise upper bound here. Consequently, there are borderline cases of groups at the expense of which you are permitted to save your friend. This essay discusses the question of what explains ethical vagueness like this, arguing that there are interesting metaethical consequences of various explanations.

Evolutionary accounts of the origins of human morality may lead us to doubt the truth of our moral judgments. Sidgwick tried to vindicate ethics from this kind of external attack. However, he ended The Methods in despair over another problem—an apparent conflict between rational egoism and universal benevolence, which he called the “dualism of practical reason.” Drawing on Sidgwick, we show that one way of defending objectivity in ethics against Sharon Street’s recent evolutionary critique also puts us in a position (...) to support a bold claim: the dualism of practical reason can be resolved in favor of impartiality.

Libertarian self-ownership views have traditionally maintained that we enjoy very powerful deontological protections against any infringement upon our property. This stringency yields very counter-intuitive results when we consider trivial infringements such as very mildly toxic pollution or trivial risks such having planes fly overhead. Maintaining that other people's rights against all infringements are very powerful threatens to undermine our liberty, as Nozick saw. In this paper I consider the most sophisticated attempts to rectify this problem within a libertarian self-ownership framework. (...) I argue that all of these responses are significantly flawed.

In his book A Theory of Justice, John Rawls introduces and employs the concept of “reflective equilibrium” as a method of testing which of rival moral theories is to be preferred. The introduction of this concept is plainly a significant event for moral philosophy. The criterion by which we decide to reject, say, utilitarianism in favour of a contractual theory of justice is, if anything, even more fundamental than the choice of theory itself, since our choice of moral theory may (...) well be determined by the criterion we use.

The libertarian view of freedom has attracted considerable attention in the past three decades. It has also been subjected to numerous criticisms regarding its nature and effects on society. G. A. Cohen''s recent book, Self-Ownership, Freedom and Equality, continues this attack by linking libertarian views on freedom to their view of self-ownership. This paper formulates and evaluates Cohen''s major arguments against libertarian freedom and self-ownership. It contends that his arguments against the libertarian rights definition of freedom are inadequate and need (...) modification. Similarly, Cohen''s defense of restrictions on self-ownership on behalf of autonomy are also found wanting. Finally, I argue that the thesis of self-ownership (whether in its full or partial version) ought to be rejected. (shrink)

This chapter explores the implications of moral vagueness for non-naturalist metaethical theories like those recently championed by Shafer-Landau, Parfit, and others. It characterizes non-naturalism in terms of its commitment to seven theses: Cognitivism, Correspondence, Atomism, Objectivism, Supervenience, Non-reductivism, and Rationalism. It starts by offering a number of reasons for thinking that moral predicates are vague in the same way in which “red,” “tall,” and “heap” are said to be. It then argues that the moral non-naturalist seeking to countenance moral vagueness (...) faces a dilemma: are moral properties vague, or perfectly sharp? On either horn of the dilemma, serious problems arise for some of the central tenets of non-naturalism: vague properties seem to threaten Objectivism, Supervenience, and Non-reductivism; on the other hand, sharp properties raise problems for Supervenience and Rationalism. The difficulties on each horn of the dilemma are real, and while they may not be insuperable, they do, at the very least, drastically limit the things non-naturalists can consistently say about moral properties, facts, and reasons.

It is natural for those with permissive attitudes toward abortion to suppose that, if they have examined all of the arguments they know against abortion and have concluded that they fail, their moral deliberations are at an end. Surprisingly, this is not the case, as I argue. This is because the mere risk that one of those arguments succeeds can generate a moral reason that counts against the act. If this is so, then liberals may be mistaken about the morality (...) of abortion. However, conservatives who claim that considerations of risk rule out abortion in general are mistaken as well. Instead, risk-based considerations generate an important but not necessarily decisive reason to avoid abortion. The more general issue that emerges is how to accommodate fallibilism about practical judgment in our decision-making. (shrink)

Anyone who reflects on the way we go about arguing for or against moral claims is likely to be struck by the central importance we give to thinking about cases. Intuitive reactions to cases—real or imagined—are carefully noted, and then appealed to as providing reason to accept various claims. When trying on a general moral theory for size, for example, we typically get a feel for its overall plausibility by considering its implications in a range of cases. Similarly, when we (...) try to refine the statement of a principle meant to cover a fairly specific part of morality, we guide ourselves by testing the various possible revisions against a carefully constructed set of cases. And when arguing against a claim, we take ourselves to have shown something significant if we can find an intuitively compelling counterexample, and such counterexamples almost always take the form of a description of one or another case where the implications of the claim in question seem implausible. Even when we find ourselves faced with a case where we have no immediate and clear reaction, or where we have such a reaction, but others don't share it and we need to persuade them, in what is probably the most common way of trying to make progress we consider various analogies and disanalogies; that is to say, we appeal to still other cases, and by seeing what we want to say there, we discover what it is plausible to say in the original case. In these and other ways, then, the appeal to cases plays a central and ubiquitous role in our moral thinking. (shrink)

In this paper I develop a framework for understanding ontic vagueness. The project of the paper is two-fold. I first outline a definitional account of ontic vagueness – one that I think is an improvement on previous attempts because it remains neutral on other, independent metaphysical issues. I then develop one potential manifestation of that basic definitional structure. This is a more robust (and much less neutral) account which gives a fully classical explication of ontic vagueness via modal concepts. The (...) overarching aim is to systematically investigate the puzzling question of what exactly it could be for the world itself to be vague. (shrink)

This book argues for a view in which processes of dialogue and interaction are taken to be foundational to reasoning, logic, and meaning. This is both a continuation, and a substantial modification, of an inferentialist approach to logic. As such, the book not only provides a critical introduction to the inferentialist view, but it also provides an argument that this shift in perspective has deep and foundational consequences for how we understand the nature of logic and its relationship with meaning (...) and reasoning. This has been upheld by several technical results, including, for example a novel approach to logical paradox and logical revision, and an account of the internal justification of logical rules. The book shows that inferentialism is greatly strengthened, such that it can answer the most stringent criticisms of the view. This leads to a view of logic that emphasizes the dynamics of reasoning, provides a novel account of the justification and normativity of logical rules, thus leading to a new, attractive approach to the foundations of logic. The book addresses readers interested in philosophy of language, philosophical and mathematical logic, theories of reasoning, and also those who actively engage in current debates involving, for example, logical revision, and the relationship between logic and reasoning, from advanced undergraduates, to professional philosophers, mathematicians, and linguists.

A question that has recently attracted considerable attention is this: What is the nature and significance of the normative relationship a person bears to herself ? On one view, it is held that persons are self-owners : as Locke put it in one of the more famous passages in the Second Treatise : [E]very man has a property in his own person : this no body has any right to but himself. The labour of his body, and the work of (...) his hands, we may say, are properly his. (shrink)

Methods and goals in philosophy are discussed by first describing an ideal, and then looking at how the ideal might be approached. David Lewis’s work in metaphysics is critically examined and compared to analogous work by Mackie and Carnap. Some large-scale philosophical systematic work, especially in metaphysics, is best treated as model-building, in a sense of that term that draws on the philosophy of science. Models are constructed in a way that involves deliberate simplification, or other imaginative modification of reality, (...) in order to make relationships visible or problems tractable. (shrink)

From the standpoint of libertarian ideology, capitalism is a form of liberation. In contrast to the slave, whose productive powers are wholly owned by his master, and the serf, whose productive powers are partially owned by his lord, the worker under capitalism is presented as possessing the fullest possible self-ownership. That capitalism fosters self-ownership is a false and stultifying myth. Exposing its errors from within capitalism's own conceptual framework requires a careful analysis of the concept of a person's “ownership” bodh (...) of his or her productive powers and of the means of exercising these productive powers. This analysis will show that, in certain plausible circumstances, the capitalist economic system can make full self-ownership impossible. Since capitalism's supposed nurturing of self-ownership provides one of the major justifications for its moral legitimacy, capitalist ideology has a serious internal inconsistency. (shrink)

You face two buttons. Pushing one will destroy Greensboro. Pushing the other will save it. There is no way for you to know which button saves and which destroys. What ought you to do? Answer: You ought to make the correct guess and push the button that saves Greensboro. Second question: Do you have an obligation to push the correct button?

is an important principle, worthy of serious scrutiny. Its truth or falsity bears on the question of whether moral rightness, obligatoriness, etc., are a matter of factors “internal” to an agent, or whether “external” factors are relevant to determining the moral normative status of acts. Moreover, Access enjoys considerable intuitive support. If I destroy Greensboro in professor Sorensen’s example by pushing the wrong button, I seem to have a good excuse to give to anyone who would accuse me of wrongdoing: (...) “I had no way of knowing that this action would be wrong!” But if I have a good excuse, then pushing the button doesn’t seem wrong; and if that action isn’t wrong, then I had no obligation to refrain from pushing that button. A principle distinct from, but analogous to, Access also deserves our attention. (shrink)

1. IntroductionThe Emotional Construction of Morals is a tour de force that combines empirical data and philosophical argument in an impressively coherent way. Certainly it resists any sweeping assessment; a mere presentation of the principal lines of argument would itself take the space of an article. Also, and despite its systematic structure, I do not think Prinz's view places decisive weight on any small number of points. Consequently, I do not think it can be refuted in any wholesale way. Nevertheless, (...) I often find myself in very sharp disagreement with Prinz. What I would like to do in this article, therefore, is to focus on what seem to be some broad issues of perspective, and see if I can convince readers that taking a slightly different perspective on certain matters might undermine the apparent force of much of what he has to say. In particular, I will focus on the analogy between moral properties and colour properties: an analogy to which Prinz himself appeals. As a corollary I will also try to show that Prinz's focus, for many purposes, on cannibalism and issues of sexual morality undermines the relevance of much of the empirical data he brings to bear in defending his sentimentalist moral theory.According to Prinz, moral judgements are manifestations of complex emotional dispositions that he calls ‘sentiments’. But unlike the expressivist, who might easily embrace the spirit of this claim, Prinz also holds that the existence of these sentiments is sufficient to generate moral properties and facts; moral properties are simply powers to activate our moral sentiments, and it is often a fact that an action has such a property. In holding moral properties to be powers of this sort, Prinz embraces both an analogy with colours, and a certain understanding of what colours are: secondary qualities understood …. (shrink)
