Methodological Naturalism in Metaethics

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics

Darwinism in metaethics: What if the universal acid cannot be contained?

The aim of this article is to explore the impact of Darwinism in metaethics and dispel some of the confusion surrounding it. While the prospects for a Darwinian metaethics appear to be improving, some underlying epistemological issues remain unclear. We will focus on the so-called Evolutionary Debunking Arguments (EDAs) which, when applied in metaethics, are defined as arguments that appeal to the evolutionary origins of moral beliefs so as to undermine their epistemic justification. The point is that an epistemic disanalogy can be identified in the debate on EDAs between moral beliefs and other kinds of beliefs, insofar as only the former are regarded as vulnerable to EDAs. First, we will analyze some significant debunking positions in metaethics in order to show that they do not provide adequate justification for such an epistemic disanalogy. Then, we will assess whether they can avoid the accusation of being epistemically incoherent by adopting the same evolutionary account for all kinds of beliefs. In other words, once it is argued that Darwinism has a corrosive impact on metaethics, what if its universal acid cannot be contained

Variance Theses in Ontology and Metaethics

The chapter illustrates conceptual engineering by bringing up a number of issues in metaontology and metaethics. A prominent debate in metaontology relates to whether some existence concept is metaphysically privileged. On the one hand, ontological realists say yes, and, on the other hand, friends of quantifier variance say no. The chapter brings up the corresponding question in metaethics by asking, is some rightness concept normatively privileged? It investigates this question, and compares the metaethics case and the metaontology case. One aim is to arrive at conclusions regarding possible limits to the project of conceptual engineering.</p

What if God commanded something horrible? A pragmatics-based defence of divine command metaethics

The objection of horrible commands claims that divine command metaethics is doomed to failure because it is committed to the extremely counterintuitive assumption that torture of innocents, rape, and murder would be morally obligatory if God commanded these acts. Morriston, Wielenberg, and Sinnott-Armstrong have argued that formulating this objection in terms of counterpossibles is particularly forceful because it cannot be simply evaded by insisting on God’s necessary perfect moral goodness. I show that divine command metaethics can be defended even against this counterpossible version of the objection of horrible commands because we can explain the truth-value intuitions about the disputed counterpossibles as the result of conversational implicatures. Furthermore, I show that this pragmatics-based defence of divine command metaethics has several advantages over Pruss’s reductio counterargument against the counterpossible version of the objection of horrible commands

Conceptual Analysis in Metaethics

A critical survey of various positions on the nature, use, possession, and analysis of normative concepts. We frame our treatment around G.E. Moore’s Open Question Argument, and the ways metaethicists have responded by departing from a Classical Theory of concepts. In addition to the Classical Theory, we discuss synthetic naturalism, noncognitivism (expressivist and inferentialist), prototype theory, network theory, and empirical linguistic approaches. Although written for a general philosophical audience, we attempt to provide a new perspective and highlight some underappreciated problems about normative concepts

Rorty’s Promise in Metaethics

Little attention is given to Richard Rorty’s metaethical views. No doubt this stems from the fact that most commentators are more interested in his metaphilosophical views; most see his metaethical views, offered in scattered passages, as just the downstream runoff from higher-level reflection. This article considers Rorty’s metaethics on their own merits, quite apart from whether his global picture works. I ultimately argue that Rorty’s metaethical outlook is attractive but beset by internal difficulties. Specifically, I contend that Rorty does not and cannot remain faithful to the methodological approach to metaethics for which he advocates. At the paper’s close, I gesture at a nearby methodological approach that best approximates Rorty’s metaethical methodology

The Significance of Ethical Disagreement for Theories of Ethical Thought and Talk

This chapter has two sections, each focusing on a distinct way in which ethical disagreement and variations in ethical judgment matter for theories of ethical thought and talk. In the first section, we look at how the variation poses problems for both cognitivist and non-cognitivist ways of specifying the nature of ethical judgments. In the second, we look at how disagreement phenomena have been taken to undermine cognitivist accounts, but also at how the seeming variation in cognitive and non-cognitive contents between parties of deep ethical disagreement challenges both cognitivist and non-cognitivist accounts of disagreement itself

Nietzsche and contemporary metaethics

Recent decades have witnessed a flurry of interest in Nietzsche's metaethics — his views, if any, on metaphysical, epistemological, semantic, and psychological issues about normativity and normative language and judgment. Various authors have highlighted a tension between Nietzsche's metaethical views about value and his ardent endorsement of a particular evaluative perspective: Although Nietzsche makes apparently "antirealist" claims to the effect that there are no evaluative facts, he vehemently engages in evaluative discourse and enjoins the "free spirits" to create values. Nearly every major type of metaethical "-ism" has been ascribed to Nietzsche in response. This chapter provides a critical introduction to Nietzsche's metaethics, focusing on matters concerning the nature and grounds of normativity. I begin by examining and raising challenges for Nadeem Hussain's prominent interpretation of Nietzsche as a revolutionary fictionalist. I argue that a constructivist interpretation (developed elsewhere) provides an improved account of the connections, for Nietzsche, between evaluative attitudes and the nature of value, and among practical nihilism, art, and value creation. Values, on this view, are treated as grounded purely in facts about creatures’ evaluative attitudes. The chapter concludes by considering several alternative subjectivist, constitutivist, and non-cognitivist interpretations. A nuanced understanding of the space of metaethical theories brings into relief a plausible normative and metanormative view that we can attribute to Nietzsche

Explanatory Challenges in Metaethics

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments
