I argue that Mackie's approach to practical reasons is attractive and unjustly neglected. In particular I argue that it is much more plausible than the kind of instrumentalist approach famously articulated by Bernard Williams. This matters for Mackie's arguments for moral skepticism. Contra Richard Joyce, I argue that it is a serious mistake to invoke instrumentalism in arguing for moral skepticism.

In recent attempts to characterize the cognitive mechanisms underlying altruistic motivation, one central question is the extent to which the capacity for altruism depends on the capacity for understanding other minds, or ‘mindreading’. Some theorists maintain that the capacity for altruism is independent of any capacity for mindreading; others maintain that the capacity for altruism depends on fairly sophisticated mindreading skills. I argue that none of the prevailing accounts is adequate. Rather, I argue that altruistic motivation depends on a basic (...) affective system, a ‘Concern Mechanism’, which requires only a minimal capacity for mindreading. (shrink)

One class of central debates between normative realists appears to concern whether we should be naturalists or reductionists about the normative. However, metaethical discussion of naturalism and reduction is often inconsistent, murky, or uninformative. This can make it hard to see why commitments relative to these metaphysical categories should matter to normative realists. This paper aims to clarify the nature of these categories, and their significance in debates between normative realists. I develop and defend what I call the joint-carving taxonomy, (...) which builds on David Lewis’ notion of elite properties. I argue that this taxonomy is clear and metaphysically interesting, and answers to distinctive taxonomic interests of normative realists. I also suggest that it has important implications for the project of adjudicating debates among normative realists. (shrink)

The metaphysical dispute between moral realists and antirealists is cast in terms of properties: the realist holds that moral properties exist, the antirealist denies this claim. There is a longstanding philosophical dispute over the nature of properties, and the obscurity of properties may make the realist/antirealist dispute even more obscure. In the spirit of deflationary theories of truth, we can turn to a deflationary theory of properties in order to clarify this issue. One might reasonably worry that such an account (...) of properties would not be capable of properly characterizing disputes regarding the existence or nonexistence of genuine moral properties. In this paper, I will show that, within this framework, the traditional disputes over the existence of moral properties can be characterized in a far clearer fashion than is usually the case. A deflationary account of properties, along with an explanatory hierarchy of properties, makes the dispute in ontology clear. (shrink)

In ‘A Dialogue’, Hume offers an important reply to the moral skeptic. Skeptics traditionally point to instances of moral diversity in support of the claim that our core values are fixed by enculturation. Hume argues that the skeptic exaggerates the amount of variation in moral codes, however, and fails to adopt an indulgent stance toward attitudes different from ours. Hume proposes a charitable interpretation of moral disagreement, moreover, which traces it back to shared principles of human nature. Contemporary philosophers attempt (...) to locate examples of moral variability that cannot be accommodated in this way. But they are no more successful than their predecessors. Moral skeptics have not found a single case of moral diversity that is resistant to the Humean strategy. (shrink)

The metatethical position known as motive internalism (MI) holds that moral beliefs are necessarily motivating. Adina Roskies (in Philosophical Psychology, 16) has recently argued against MI by citing patients with injuries to the ventromedial (VM) cortex as counterexamples to MI. Roskies claims that not only do these patients not act in accordance with their professed moral beliefs, they exhibit no physiological or affective evidence of being motivated by these beliefs. I argue that Roskies' attempt to falsify MI is unpersuasive because (...) the evidence used to attribute the relevant moral beliefs to VM patients is insufficient: Contra Roskies, that VM patients are proficient moral reasoners does not establish the presence of these moral beliefs. In addition, the linguistic evidence Roskies cites (a) is vulnerable to methodological worries about its reliability or authenticity, (b) does not override counterevidence derived from the patients' nonlinguistic behavior, and (c) is undermined by VM patients' inability to correctly attribute moral beliefs to others. I conclude with a proposal about how MI should be interpreted, given that it is not falsified by empirical evidence of the sort put forth by Roskies. (shrink)

Current debate in metaethics includes the question of objectivity. What does it mean for a moral prescription to be objective? It is easy to see how matters of fact are objective, and it is also easy to see how matters of taste are subjective. But what about matters of morality? Given the diversity in moral beliefs and practices it appears these cannot be matters of fact. Are they thus matters of taste? If so, we are left with the unlivable conclusion (...) that all moral prescriptions are beyond rational scrutiny. David Hume expressed these problems in a way that continues to be influential today: ‘Tis as little contrary to reason to prefer even my own acknowled'd lesser good to my greater’ (Hume, 2003: 2.III.ii). Resolving problems about moral objectivity is further complicated by the philosophical presuppositions of analytic philosophy that have dominated the 20th century, initiated in the work of G.E. Moore, and promulgated in theories such as logical positivism and ordinary language philosophy. Contemporary thinkers from both the cognitivist and the non‐cognitivist camps have tried to demonstrate that moral claims are objective in the sense of being subject independent. By considering contemporary appeals to the ideally rational self to establish objectivity, and objections to rationality as a ground for objectivity, it will be argued that objectivity can be grounded in the good which in turn is grounded in human nature. This approach can be found in the Socratic denial of knowingly doing evil, and out of this a foundation for moral objectivity can be developed that does not require an appeal to the individual's mental state and which preserves individual responsibility for knowing the good.

There has been a great deal of discussion in the recent philosophical literature of the relationship between the minimalist theory of truth and the expressivist metaethical theory. One group of philosophers contends that minimalism and expressivism are compatible, the other group contends that such theories are incompatible. Following Simon Blackburn (manuscript), I will call the former position ‘compatibilism’ and the latter position ‘incompatiblism.’ Even those compatibilist philosophers who hold that there is no conflict or tension between these two theories—minimalism and (...) expressivism—typically think that some revision of minimalism is required to accommodate expressivism. The claim that there is such an incompatibility, I will argue, is based on a misunderstanding of the historical roots of expressivism, the motivations behind the expressivist theory, and the essential commitments of expressivism. I will present an account of the expressivist theory that is clearly consistent with minimalism. (shrink)

This essay offers a defence of the non-cognitivist approach to the interpretation of moral judgments as disguised imperatives corresponding to social rules. It addresses the body of criticism that faced R. M. Hare, and that currently faces moral anti-realists, on two levels, by providing a full semantic analysis of evaluative judgments and by arguing that anti-realism is compatible with moral aspiration despite the non-existence of obligations as the externalist imagines them. A moral judgment consists of separate descriptive and prescriptive components (...) and is to be understood as a declarative statement prefaced by an 'ideality operator'. Moral beliefs are genuinely representational, but their truth conditions can only be stated with reference to imaginary ideal worlds. Moral judgments are neither confirmed nor verified, but alternative moral positions are preferentially endorsed and adopted by individual agents on the basis of their perceived all-things-considered optimality. High aspiration moralities are normally very costly to agents in terms of their prudential and aesthetic interests, but they are theoretically as eligible as the adoption of other, less demanding sets of rules.

Moore's Open Question Arguments are among the most influential arguments in 20th Century metaethical thought. But, surprisingly, there is a fair amount of confusion concerning what the Open Question Arguments actually are, how the Moorean passages should be interpreted, and what they are intended to show. Thus, the early chapters are devoted to clarificatory matters, including the exposing of a variety of contemporary attacks upon Moore's arguments as misguided by indicating where they rest upon faulty interpretations of Moorean passages. Providing (...) what I take to be accurate formulations of Moore's famous arguments, responding to historically important preliminary objections, and, finally, presenting various shortcomings of these arguments constitute the remaining themes of the early chapters. ;Next, I pursue an explanation of what I call the 'Open Question phenomenon': the inclination that many have to endorse Moore's "open question" premises. I survey a variety of popular noncognitivist explanations, arguing that each of them is unsatisfactory. I then present a novel semantic explanation of the phenomenon and use it to construct an augmented Moorean Open Question Argument, one capable of overcoming the shortcomings of Moore's originals. ;The latter chapters are dedicated to an investigation of Moore's preferred normative theory---a version of objective consequentialism. I argue that the standard semantic account of subjunctive conditionals fails to capture the nature of certain subjunctive conditionals relevant to the normative evaluation of alternatives from an objective consequentialist perspective. I then present a modified version of the standard account in an effort to remedy the problem. ;Next, I present a novel objection against all extant versions of objective consequentialism. I then introduce and utilize the concept of an "objective" subjunctive probability in the transformation of a subjective version of consequentialism into an objective version, one capable of dealing with the difficulties posed by the objection. ;I conclude the dissertation with a final chapter in which I defend possibilist versions of consequentialism from a contemporary objection. In doing so, I elucidate a theoretical advantage that possibilist theories have over their subjunctive counterparts. (shrink)
