The prospects for moral realism and ethical naturalism have been important parts of recent debates within metaethics. As a first approximation, moral realism is the claim that there are facts or truths about moral matters that are objective in the sense that they obtain independently of the moral beliefs or attitudes of appraisers. Ethical naturalism is the claim that moral properties of people, actions, and institutions are natural, rather than occult or supernatural, features of the world. Though these metaethical debates (...) remain unsettled, several people, myself included, have tried to defend the plausibility of both moral realism and ethical naturalism. I, among others, have appealed to recent work in the philosophy of language—in particular, to so-called theories of “direct reference” —to defend ethical naturalism against a variety of semantic worries, including G. E. Moore's “open question argument.” In response to these arguments, critics have expressed doubts about the compatibility of moral realism and direct reference. In this essay, I explain these doubts, and then sketch the beginnings of an answer—but understanding both the doubts and my answer requires some intellectual background. (shrink)

Contemporary realist theories of value claim to be compatible with natural science. In this paper, I call this claim into question by arguing that Darwinian considerations pose a dilemma for these theories. The main thrust of my argument is this. Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes. The challenge for realist theories of value is to explain the relation between these evolutionary influences on our evaluative attitudes, on the one hand, and the (...) independent evaluative truths that realism posits, on the other. Realism, I argue, can give no satisfactory account of this relation. On the one hand, the realist may claim that there is no relation between evolutionary influences on our evaluative attitudes and independent evaluative truths. But this claim leads to the implausible skeptical result that most of our evaluative judgements are off track due to the distorting pressure of Darwinian forces. The realist’s other option is to claim that there is a relation between evolutionary influences and independent evaluative truths, namely that natural selection favored ancestors who were able to grasp those truths. But this account, I argue, is unacceptable on scientific grounds. Either way, then, realist theories of value prove unable to accommodate the fact that Darwinian forces have deeply influenced the content of human values. After responding to three objections, the third of which leads me to argue against a realist understanding of the disvalue of pain, I conclude by sketching how antirealism is able to sidestep the dilemma I have presented. Antirealist theories of value are able to offer an alternative account of the relation between evolutionary forces and evaluative facts —
an account that allows us to reconcile our understanding of evaluative truth with our understanding of the many non-rational causes that have played a role in shaping our evaluative judgements. (shrink)

This is a paper about the problem of realism in meta-ethics (and, I hope, also in other areas, but that hope is so far pretty speculative). But it is not about the problem of whether realism is true. It is about the problem of what realism is. More specifically, it is about the question of what divides meta-ethical realists from irrealists. I start with a potted history of the Good Old Days.

This article focuses on one well-known argument in favor of expressivism and against realism that Shafer-Landau considers, namely Blackburn's supervenience argument. Shafer-Landau believes that he can successfully defend moral realism against Blackburn's argument. I have my doubts about whether this is so.

Principia Ethica set the agenda for analytical metaethics. Moore’s unrelenting focus on fundamentals both brought metaethics into view as a potentially separate area of philosophical inquiry and provided a model of the analytical techniques necessary to pursue it.1 Moore acknowledged that he wasn’t the first to insist on a basic irreducible core of all ethical concepts. Although he seems not to have appreciated the roots of this thought in eighteenth-century intuitionists like Clarke, Balguy, and Price, not to mention sentimentalists like (...) Hutcheson and Hume, Moore gave full marks to Sidgwick. According to Moore, Sidgwick was the “only . . . ethical writer” to have clearly seen the irreducibility of ethics’ defining notion.2 Nevertheless, twentieth-century meta-. (shrink)
