In this paper we shed new light on the Argument from Disagreement by putting it to test in a computer simulation. According to this argument widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by any moral facts, either because no such facts exist or because they are epistemically inaccessible or inefficacious for some other reason. Our simulation shows that if our moral opinions were influenced at least a little bit by moral facts, we (...) would quickly have reached consensus, even if our moral opinions were affected by factors such as false authorities, external political shifts, and random processes. Therefore, since no such consensus has been reached, the simulation gives us increased reason to take seriously the Argument from Disagreement. Our conclusion is however not conclusive; the simulation also indicates what assumptions one has to make in order to reject the Argument from Disagreement. The simulation algorithm we use builds on the work of Hegselmann and Krause (J Artif Soc Social Simul 5(3); 2002, J Artif Soc Social Simul 9(3), 2006). (shrink)

According to Realism about Epistemic Value, there is such a thing as epistemic value and it is appropriate to evaluate things—e.g., beliefs—for epistemic value because there is such a thing as epistemic value. Allan Hazlett's A Luxury of the Understanding is a sustained critique of Realism. Hazlett challenges proponent of Realism to answer explanatory questions while not justifiably violating certain constraints, including two proposed naturalistic constraints. Hazlett argues they cannot. Here I defend Realism. I argue that it is easy for (...) proponents of Realism to answer Hazlett's explanatory questions. The interesting issue is whether those answers violate Hazlett's naturalistic constraints. My own view is that epistemic value is irreducible to natural properties; it thus violates Hazlett's proposed constraints. I argue that this is justifiable because Hazlett fails to convincingly motivate his naturalistic constraints and there is reason for thinking epistemic value is irreducible to natural properties anyway.

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)

In her 2007 paper, “Argument Has No Function” Jean Goodwin takes exception with what she calls the “explicit function claims”, arguing that not only are function-based accounts of argumentation insufficiently motivated, but they fail to ground claims to normativity. In this paper I stake out the beginnings of a functionalist answer to Goodwin.

The claim that ordinary ethical discourse is typically true and that ethical facts are typically knowable seems in tension with the claim that ordinary ethical discourse is about features of reality friendly to a scientific worldview. Cornell Realism attempts to dispel this tension by claiming that ordinary ethical discourse is, in fact, discourse about the same kinds of things that scientific discourse is about: natural properties. We offer two novel arguments in reply. First, we identify a key assumption that we (...) find unlikely to be true. Second, we identify two features of typical natural properties that ethical properties lack. We conclude that Cornell Realism falls short of dispelling the tension between ethical conservativism and ethical naturalism. (shrink)

Selon certains philosophes, le principe « devoir-implique-pouvoir » exprime une vérité analytique et permet d’inférer des énoncés normatifs sur la base de prémisses purement descriptives. Le principe DIP offrirait ainsi un contre-exemple à la fameuse loi de Hume. Le problème est que DIP permet uniquement de construire des raisonnements dont les conclusions sont des négations de normes. Or, selon certains auteurs, les négations de normes n’expriment pas de véritables jugements moraux. En ce sens, selon eux, DIP ne permet pas de (...) tirer des conclusions normatives sur la base de prémisses uniquement descriptives. Dans cet article, nous soutenons au contraire que les négations de normes sont de véritables normes et que DIP permet bien de déduire une conclusion normative à partir de prémisses purement descriptives.

The aim of this article is to draw a sketch of an ontology for Realist Non-Naturalist Cognitivists. A distinction is made between moral property-universals and moral property-particulars. It is argued, first, that moral property-universals have the same ontological status as non-moral property-universals; second, that moral property-universals have many instances in the spatio-temporal world; third that these moral property-instances or -particulars have the same ontological status as non-moral property-particulars.

Many moral philosophers accept the Debunking Thesis, according to which facts about natural selection provide debunking explanations for certain of our moral beliefs. I argue that philosophers who accept the Debunking Thesis beg important questions in the philosophy of biology. They assume that past selection can explain why you or I hold certain of the moral beliefs we do. A position advanced by many prominent philosophers of biology implies that this assumption is false. According to the Negative View, natural selection (...) cannot explain the traits of individuals. Hence, facts about past selection cannot provide debunking explanations for any of our moral beliefs. The aim of this paper is to explore the conflict between the Debunking Thesis and the Negative View. (shrink)

Many philosophers believe that natural selection explanations debunk our moral beliefs or would do so if moral realism were true, relying on the assumption that explanations of this kind show that moral facts play no role in explaining human moral beliefs. Here I argue that this assumption rests on a confusion of proximate and ultimate explanatory factors. Insofar as evolutionary debunking arguments hinge on the assumption that moral facts play no role in explaining human moral beliefs, these arguments fall short.

In this article I survey philosophical literature on the topic of what, if anything, makes a person’s life meaningful, focusing on systematic texts that are written in English and that have appeared in the last five years (2002-2007). My aims are to present overviews of the most important, fresh, Anglo-American positions on meaning in life and to raise critical questions about them worth answering in future work.

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)

According to the fitting-attitudes account of value, for X to be good is for it to be fitting to value X. But what is it for an attitude to be fitting? A popular recent view is that it is for there to be sufficient reason for the attitude. In this paper we argue that proponents of the fitting-attitudes account should reject this view and instead take fittingness as basic. In this way they avoid the notorious ‘wrong kind of reason’ problem, (...) and can offer attractive accounts of reasons and good reasoning in terms of fittingness. (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)

Discussion of moral explanation has reached animpasse, with proponents of contemporaryethical naturalism upholding the explanatoryintegrity of moral facts and properties, andopponents – including both anti-realists andnon-naturalistic realists – insisting thatsuch robustly explanatory pretensions as moraltheory has be explained away. I propose thatthe key to solving the problem lies in thequestion whether instances of moral propertiesare causally efficacious. It is argued that,given the truth of contemporary ethicalnaturalism, moral properties are causallyefficacious if the properties of the specialsciences are. Certain objections are rebuttedinvolving (...) the nature of causation, on the onehand, and putative special features of themoral realm, on the other. (shrink)

The paper distinguishes three strategies by means of which empirical discoveries about the nature of morality can be used to undermine moral judgements. On the first strategy, moral judgements are shown to be unjustified in virtue of being shown to rest on ignorance or false belief. On the second strategy, moral judgements are shown to be false by being shown to entail claims inconsistent with the relevant empirical discoveries. On the third strategy, moral judgements are shown to be false in (...) virtue of being shown to be unjustified; truth having been defined epistemologically in terms of justification. By interpreting three recent error theoretical arguments in light of these strategies, the paper evaluates the epistemological and metaphysical relevance of empirical discoveries about morality as a naturally evolved phenomenon.

In a series of articles, Terry Horgan and Mark Timmons have argued that Richard Boyd’s defence of moral realism, utilizing a causal theory of reference, fails. Horgan and Timmons construct a twin Earth-style thought experiment which, they claim, generates intuitions inconsistent with the realist account. In their thought experiment, the use of (allegedly) moral terms at a world is causally regulated by some property distinct from that regulating their use here on Earth; nevertheless, Horgan and Timmons claim, it is intuitive (...) that the inhabitants of this world disagree with us in their moral claims. Since any disagreement would be merely verbal were the alleged moral facts identical to or constituted by different natural facts, the identity or constitution claim must be false. I argue that their argument fails. Horgan and Timmons’ thought experiment is underdescribed; when we fill out the details, I claim, we shall see that the challenge to moral realism fades away. I sketch two possible interpretations of the (apparently) moral claims of the inhabitants of moral Twin Earth. On one interpretation, they fail to disagree with us because they actually agree with us; on the other, they fail to disagree with us because they are not moralizers at all. Which interpretation is true, I argue, will depend on the facts that explain the differences between us and the inhabitants of moral twin Earth. (shrink)

A prominent argument for moral realism notes that we are inclined to accept realism in science because scientific inquiry supports a robust set of critical practices—error, improvement, explanation, and the like. It then argues that because morality displays a comparable set of critical practices, a claim to moral realism is just as warranted as a claim to scientific realism. But the argument is only as strong as its central analogy—and here there is trouble. If the analogy between the critical practices (...) of science and morality is loosely interpreted, the argument does not support moral realism—for paradigmatically constructivist discourses like fashion display the relevant critical practices just as well. So if the argument is to have force, the realist must say more about why the critical practices of morality are sufficiently like those of science to warrant realism. But this cannot be done—moral inquiry differs from scientific inquiry in too many important ways. So the analogy with the critical practices of science fails to vindicate moral realism. But there are further lessons: in looking closely at the critical practices of our moral discourse—and in comparing them to the critical practices of science and fashion—we gain insight into what is distinctive about morality objectivity and moral metaphysics.

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples (...) to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits. (shrink)

Moral intuitionism, once an apparently moribund metaethical position, has seen a resurgence of interest of late. Robert Audi, a leading moral intuitionist, has argued that in order for a moral belief to qualify as intuitional, it must fulfill four criteria: it must be non-inferential, firmly held, comprehended, and pre-theoretical. This paper centers on the fourth and seemingly most problematic criterion: pre-theoreticality. The paper begins by stipulating the defensibility of the moral cognitivism upon which moral intuitionism turns. Next, the paper develops (...) the distinction between semantic and epistemic pre-theoreticality, and goes on to explore and reject the putative ubiquity of the theoreticality of first-order moral discourse: it argues that on a defensible understanding of theoryhood, both semantic and epistemic pre-theoretical moral belief is not only possible, but in fact frequently realized. The paper then briefly explores and rebuts objections to (epistemic) pre-theoreticality issuing from (i) the “Cornell Realists” and (ii) considerations of the epistemic relevance of the epistemic/valuational background of moral belief. The paper concludes that, so far as the pre-theoreticality criterion is concerned, moral intuitionism remains in the running as a viable thesis regarding foundationally justified first-order moral belief and knowledge.

Normative political philosophy always refers to a standard against which a society's institutions are judged. In the first, analytical part of the article, the different possible forms of normative criticism are examined according to whether the standards it appeals to are external or internal to the society in question. In the tradition of Socrates and Hegel, it is argued that reconstructing the kind of norms that are implicit in practices enables a critique that does not force the critic's particular views (...) on the addressee and can also be motivationally effective. In the second part of the article, Axel Honneth's theory of recognition is examined as a form of such reconstructive internal critique . It is argued that while the implicit norms of recognition made explicit in Honneth's philosophical anthropology help explain progressive social struggles as moral ones, his theory faces two challenges in justifying internal critique. The Priority Challenge asks for the reasons why the implicit norms of recognition should be taken as the standard against which other implicit and explicit norms are to be judged. The Application Challenge asks why a social group should, by its own lights, extend equal recognition to all its members and even non-members. The kind of functional, prudential, conceptual, and moral considerations that could serve to answer these challenges are sketched. (shrink)

Scanlon’s Being Realistic about Reasons (BRR) is a beautiful book – sleek, sophisticated, and programmatic. One of its key aims is to demystify knowledge of normative and mathematical truths. In this article, I develop an epistemological problem that Scanlon fails to explicitly address. I argue that his “metaphysical pluralism” can be understood as a response to that problem. However, it resolves the problem only if it undercuts the objectivity of normative and mathematical inquiry.

J. L. Mackie argued that if there were objective moral properties or facts, then the supervenience relation linking the nonmoral to the moral would be metaphysically queer. Moral realists reply that objective supervenience relations are ubiquitous according to contemporary versions of metaphysical naturalism and, hence, that there is nothing especially queer about moral supervenience. In this paper we revive Mackie's challenge to moral realism. We argue: (i) that objective supervenience relations of any kind, moral or otherwise, should be explainable rather (...) than sui generis; (ii) that this explanatory burden can be successfully met vis-à-vis the supervenience of the mental upon the physical, and in other related cases; and (iii) that the burden cannot be met for (putative) objective moral supervenience relations. (shrink)

I argue for three principle claims. First, philosophers who seek to integrate the semantic and the intentional into a naturalistic metaphysical worldview need to address a task that they have thus far largely failed even to notice: explaining into- level connections between the physical and the intentional in a naturalistically acceptable way. Second, there are serious reasons to think that this task cannot be carried out in a way that would vindicate realism about intentionality. Third, there is much to be (...) said for an irrealist, non-eliminativist, naturalistic approach to intentionality that I call "preservative irrealism". (shrink)

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver (...) is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)

I begin by describing my relation with Nicholas Sturgeon and his objections to things I have said about moral explanations. Then I turn to issues about moral relativism. One of these is whether a plausible version of moral relativism can be formulated as a claim about the logical form of certain moral judgments. I agree that is not a good way to think of moral relativism. Instead, I think of moral relativism as a version of moral realism. I compare moral (...) relativism with the relativity of motion and with the relativity of language. Moralities are real in a way that is similar to the way that languages are real. Next I discuss resemblances between nonhuman animal behavior and human behavior having to do with language or communication and with moral or proto-moral behavior. However, I am more interested in aspects of language and morality that are not found in nonhuman animals, aspects that appear to depend on a kind of recursive structure in human language and morality but not in animals. This leads me to argue that aspects of moral theory might benefit from a comparison with certain aspects of linguistic theory. Another comparison is between moralities and legal systems: I speculate that the content of legal and moral systems is influenced by legal and moral bargaining. (shrink)

The challenge of Gilbert Harman that there are no moral facts is robust, to an extent extreme and counts most for the realists underline moral facts and moral explanations. The paper begins with the absorbing challenge posed by Harman that ends in some sort of skepticism. After a brief exposition of nature of moral facts, the paper focuses on another interesting squabble whether or not we conceive of serious moral explanation that bridges the gap between theories/ principles, and our moral (...) observations. In a separate section it has been shown that moral explanations are far too necessary for moral facts because moral facts need to have explanatory potency. Moral facts need to explain our observations of moral phenomena. The contentious issue has been addressed remarkably well by Nicholas Sturgeon and Brad Majors. I have a suggestion that cogency of ideas of moral facts and moral explanations depend among other things, on the conception of possible worlds. (shrink)

Ethical disputes arise over differences in the content of the ethical beliefs people hold on either side of an issue. One person may believe that it is wrong to have an abortion for financial reasons, whereas another may believe it to be permissible. But, the magnitude and difficulty of such disputes may also depend on other properties of the ethical beliefs in question—in particular, how objective they are perceived to be. As a psychological property of moral belief, objectivity is relatively (...) unexplored, and we argue that it merits more attention. We review recent psychological evidence which demonstrates that individuals differ in the extent to which they perceive ethical beliefs to be objective, that some ethical beliefs are perceived to be more objective than others, and that both these sources of variance are somewhat systematic. This evidence also shows that differences in perceptions of objectivity underpin quite different psychological reactions to ethical disagreement. Apart from reviewing this evidence, our aim in this paper is to draw attention to unanswered psychological questions about moral objectivity, and to discuss the relevance of moral objectivity to two issues of public policy.

It is often claimed that there is an explanatory divide between an expressivist account of normative discourse and a realist conception of normativity: more precisely, that expressivism and realism offer conflicting explanations of (i) the metaphysical structure of the normative realm, (ii) the connection between normative judgment and motivation, (iii) our normative beliefs and any convergence thereof, or (iv) the content of normative thoughts and claims. In this paper I argue that there need be no such explanatory conflict. Given a (...) minimalist approach to the relevant metaphysical and semantic notions, expressivism is compatible with any explanation that would be acceptable as a general criterion for realism. (shrink)

Fictionalism about a kind of disputed object is often motivated by the fact that the view interprets discourse about those objects literally without an ontological commitment to them. This paper argues that this motivation is inadequate because some viable alternatives to fictionalism have similar attractions. Meinongianism—the view that there are true statements about non-existent objects—is one such view. Meinongianism bears significant similarity to fictionalism, so intuitive doubts about its viability are difficult to sustain for fictionalists. Moreover, Meinongianism avoids some of (...) fictionalism’s weaknesses, thus it is even preferable to fictionalism in some respects. (shrink)

Terry Horgan and Mark Timmons’s “Moral Twin Earth” thought experiment allegedly undercuts virtually any form of naturalist moral realism. I argue that a neo-Aristotelian conception of moral properties defeats Moral Twin Earth. Developing themes in the work of Peter Geach, Philippa Foot, and Rosalind Hursthouse, I sketch an Aristotelian moral semantics that is unique in construing terms like ‘right’ and ‘good’ exclusively as attributive adjectives that denote relational properties. On this view, moral goodness is a relational property predicated of those (...) human beings that satisfy kind-relative criteria of goodness; i.e., morally good human beings are good qua human being. The reference of moral terms is therefore fixed by the natural properties of human beings. This account ensures that moral facts cannot differ across worlds in which the relevant natural facts do not differ and thus defeats Moral Twin Earth. (shrink)

Non-naturalists claim that the nature of normativity precludes the possibility of normative naturalism. In particular, they think that normative reduction amounts to normative elimination. This is because it always leaves out the normative. In this paper, I examine the force that the normativity objection has against Humean reductionism. I argue that the normativity objection has no argumentative force against reductionism. When it is presented as a bare intuition, it begs the question against reduction. A more interesting reading of the argument (...) claims that the normative cannot be explained in terms of the natural because the natural is arbitrary. Yet, this version of the argument fails as well because the natural is not arbitrary in the relevant sense. The natural is contingent, so what has value is contingent. That is not an elimination of the normative though, because contingent reasons are still reasons. (shrink)

This paper addresses two related questions. First, what is involved in giving a distinctively realist and naturalist construal of an area of discourse, that is, in so much as stating a distinctively realist and naturalist position about, for example, content or value? I defend a condition that guarantees the realism and naturalism of any position satisfying it, at least in the case of positions on content, but perhaps in other cases as well. Second, what sorts of considerations render a distinctively (...) realist and naturalist position more plausible than its irrealist and non-naturalist rivals? The answer here focuses again on theories of content and is wholly negative. I argue that the standard array of arguments offered in support of realist and naturalist theories in fact provide equal support for a host of irrealist and non-naturalist ones. Taken together, these considerations reveal an important gap in the recent philosophical literature on content. The challenge to proponents of putatively realist and naturalist theories is to insure that those theories so much as state distinctively realist and naturalist positions and then to identify arguments that support what is distinctively realist and naturalist about them.

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. (shrink)

Non-naturalism is the view that normative properties are response-independent, irreducible to natural properties, and causally inefficacious. An underexplored question for non-naturalism concerns the metasemantics of normative terms. Ideally, the non-naturalist could remain ecumenical, but it appears they cannot. Call this challenge the metasemantic challenge. This chapter suggests that non-naturalists endorse an epistemic account of reference determination of the sort recently defended by Imogen Dickie, with some modifications. An important implication of this account is that, if correct, a fully fleshed out (...) moral epistemology will simultaneously rebut metasemantic objections to non-naturalism. Thus, both the metasemantic and the more widely discussed epistemological challenges in effect amount to one. Before setting out the positive view, the chapter considers why all of the traditional metasemantic theories cause trouble for the non-naturalist. This includes discussions of teleosemantics, conceptual role semantics, as well as Schroeter and Schroeter’s “connectedness” model. (shrink)

Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while granting that these beliefs are not explained by the moral facts. We show that (...) the minimalist gambit rests on a controversial thesis about epistemic priority: that explanatory concessions derive their epistemic import from what they reveal about counterfactual connections. We then challenge this epistemic priority thesis, which undermines the minimalist response to debunking arguments (in ethics and elsewhere). (shrink)

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that moral sentences have truth-value, there are moral properties that make some moral sentences true, and moral properties are not reducible to non- moral properties. Realism is contrasted with non-cognitivism, error-theory and reductionism, which, in brief, deny, and, respectively. In the introductory chapter, it is also argued that there are some prima facie reasons to assume (...) that non-cognitivism and error-theory are erroneous. In chapters 2 and 3, I suggest that the two main forms of reductionism, analytic and synthetic reductionism, are mistaken. In chapter 4, I argue that the considerations in the previous chapters in relation to non-cognitivism, error-theory and reductionism provide support to moral realism. It is also suggested that these considerations make it plausible to hypothesise that moral properties depend on non- moral properties in a way I refer to as ‘the realist formula’. The realist formula confirms moral realism since it implies that moral properties are not reducible to non- moral properties. In chapters 5, 6 and 7, I argue that moral realism, much owing to the realist formula, is able to explain significant meta-ethical issues regarding moral disagreement, moral reason and moral motivation. Among other things, externalism concerning moral motivation is defended. The explanatory value of moral realism in relation to these meta-ethical issues is taken to suggest that this view is preferable to non-cognitivism, error-theory and reductionism. Some of the meta-ethical issues discussed in these chapters, particularly moral disagreement and motivation, have been thought to provide support to non-cognitivism and error-theory. I maintain that since realism, unlike reductionism, is able to counter these arguments, it justifies us in upholding the view that moral sentences have truth-value and the view that there are moral properties. In chapter 8, various objections against realism with regard to the dependence of moral properties on non- moral properties are responded to. In chapter 9, I consider an influential argument to the effect that moral properties are not involved in causal explanations. I maintain that this argument fails and that it therefore is reasonable to assume that moral properties are natural properties. However, the discussions in chapters 8 and 9 also suggest that moral realism might face problems that cannot be thoroughly discussed in this thesis. (shrink)

Metaethics, understood as a distinct branch of ethics, is often traced to G. E. Moore's 1903 classic, Principia Ethica. Whereas normative ethics is concerned to answer first order moral questions about what is good and bad, right and wrong, metaethics is concerned to answer second order non-moral questions about the semantics, metaphysics, and epistemology of moral thought and discourse. Moore has continued to exert a powerful influence, and the sixteen essays here represent the most up-to-date work in metaethics after, and (...) in some cases directly inspired by, the work of Moore.

Sharon Street’s evolutionary debunking argument—her Darwinian Dilemma—is meant to challenge value realists to reconcile the evaluative attitudes we tend to hold, shaped as they are by evolution, with the attitude-independent evaluative facts that realists posit. Ramon Das argues that Street’s argument relies on illicit metaphysical assumptions about evaluative facts, and that these assumptions beg the question against a particular form of value realism called naturalist realism. I argue that Street makes no such metaphysical assumptions, and that her argument requires no (...) particular metaphysical construal of evaluative facts to work. I further argue that any objection of the kind Das raises—those that turn on the metaphysical underpinnings of evaluative facts—is unlikely to succeed against Street’s Darwinian Dilemma. (shrink)

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object (...) beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

What is it that we are doing when we make ethical claims and judgments, such as the claim that we morally ought to assist refugees? This dissertation introduces and defends a novel theory of ethical thought and discourse. I begin by identifying the surface features of ethical thought and discourse to be explained, including the realist and cognitivist (i.e. belief-like) appearance of ethical judgments, and the apparent close connection between making a sincere ethical judgment and being motivated to act on (...) it. I examine prominent attempts to explain these features, with a focus on recent ‘hybrid’ theories combining elements of expressivism and cognitivism. Despite their initial promise, I argue that extant hybrid theories are nevertheless committed to problematic semantic, metasemantic, or pragmatic assumptions. I then discuss what I take to be the strongest existing option, ethical neo-expressivism (Bar-On and Chrisman, 2009; Bar-On, Chrisman, and Sias, 2014), and develop it into an explicitly hybrid theory proposing that ethical judgments incorporate both motivationally-charged affective states and moral beliefs. I then supplement this account with a theory of the proper function (following Millikan, 1984) of ethical claims and judgments, arguing that they function simultaneously to track the morally salient features of social situations, and to coordinate our behavior around these features. Finally, I defend one of the cognitivist commitments of the theory – namely, that objective moral knowledge is possible – by applying recent work on the epistemology of fundamental or ‘core’ intellectual commitments (Lynch, 2012; Pritchard, 2016) to the moral realm.

This entry addresses the nature and epistemological role of intuition by considering the following questions: (1) What are intuitions?, (2) What roles do they serve in philosophical (and other “armchair”) inquiry?, (3) Ought they serve such roles?, (4) What are the implications of the empirical investigation of intuitions for their proper roles?, and (5) What is the content of intuitions prompted by the consideration of hypothetical cases?

An overview of Dai's ethics, highlighting some overlooked or misunderstood theses on moral deliberation and motivation.

This chapter both explains the origins of emotivism in C. K. Ogden and I. A. Richards, R. B. Braithwaite, Austin Duncan-Jones, A. J. Ayer and Charles Stevenson (along with the endorsement by Frank P. Ramsey, and the summary of C. D. Broad), and looks at MacIntyre's criticisms of emotivism as the inevitable result of Moore's attack on naturalistic ethics and his ushering in the fact/value, which was a historical product of the Enlightenment.

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

In this work I defend moral realism, the thesis that there are objective moral truths, by defending “epistemic realism.” Epistemic realism is the thesis that epistemic judgments, e.g., judgments that some belief is epistemically reasonable, or justified, or known or should be held, are sometimes true and made true by stance-independent epistemic facts and properties. -/- One might think that epistemic realism needs no defense because it is obviously true and nearly universally accepted. But there are influential arguments against moral (...) realism, which is analogous to epistemic realism: moral realists think that moral judgments, e.g., that something is morally good, or ought to be done, are sometimes true because there are stance-independent moral facts and properties. Moral irrealists deny this for a variety of semantic, metaphysical, psychological and epistemological reasons. They argue that moral judgments are neither true nor false since they are non-cognitive expressions of emotion or commands, or are never true since they fail to refer, or that their truth is “relative.” -/- Drawing on the moral irrealisms of Ayer, Stevenson, Hare, Mackie, Harman, and more recent thinkers, I construct parallel arguments for epistemic irrealisms. On these views, epistemic judgments are also merely expressive, a kind of command, always false, or relativistic in truth conditions: even “epistemic platitudes” like “justified beliefs are better than unjustified beliefs” and “ideally, one’s beliefs ought to be consistent” are understood not as epistemic propositions that might be believed (much less believed truly), or as attempts to accurately represent epistemic facts, or as attributions of epistemic properties. -/- The implications of these claims are highly at odds with common epistemological assumptions, even those that moral irrealists tend to accept. I argue that these implications are rationally unacceptable and that, therefore, the premises that support them should be rejected. Since these premises are those given in defense of moral irrealisms, I thereby defend both moral and epistemic realism. Thus, I argue that “oughts,” “shoulds” and other evaluative judgments are equally legitimate in both ethics and epistemology. (shrink)
