Can a certain sort of property supervene on another sort of property without reducing to it? Many philosophers find the superveniencel irreducibility combination attractive in the philosophy of mind and in moral philosophy. They think that mental properties supervene upon physical properties but do not reduce to them, or that moral properties supervene upon natural properties without reducing to them. Other philosophers have tried to show that the combination is ultimately untenable, however attractive it might initially appear. Thus Ted Honderich (...) and Jaegwon Kim argue that the combination cannot explain the causal efhcacy of the supervening properties. And Simon. (shrink)

I consider the metaphysical consequences of the view that propositional attitudes have essential normative properties. I argue that realism should take a weak rather than a strong form. I argue that expressivism cannot get off the ground. And I argue that eliminativism is self-refuting.

A common line of thought in contemporary metaethics is that certain facts about the evolutionary history of humans make moral realism implausible. Two of the most developed evolutionary cases against realism are found in the works of Richard Joyce and Sharon Street. In what follows, I argue that a form of moral realism that I call proper-function moral realism can meet Joyce and Street's challenges. I begin by sketching the basics of proper-function moral realism. I then present what I take (...) to be the essence of Street's and Joyce's objections, and I show how proper-function realism answers them. (shrink)

Terence Cuneo has recently argued that we have to be committed to the existence of epistemic facts insofar as they are indispensable to theorizing. Furthermore, he argues that the epistemic properties of these facts are inextricably ‘ontologically entangled’ with certain moral properties, such that there exist ‘moral-epistemic’ facts. Cuneo, therefore, concludes that moral realism is true. I argue that Cuneo’s appeal to the existence of moral-epistemic facts is problematic, even granting his argument for the existence of indispensable epistemic facts. I (...) conclude, therefore, that Cuneo’s argument fails to justify moral realism. (shrink)

This essay explores the thesis that for vague predicates, uncertainty over whether a borderline instance x of red/large/tall/good is to be understood as practical uncertainty over whether to treat x as red/large/tall/good. Expressivist and quasi-realist treatments of vague predicates due to John MacFarlane and Daniel Elstein provide the stalking-horse. It examines the notion of treating/counting a thing as F , and links a central question about our attitudes to vague predications to normative evaluation of plans to treat a thing as (...) F . The essay examines how the account applies to normatively defective or contested terms. The final section raises a puzzle about the mechanics of MacFarlane’s detailed implementation for the case of gradable adjectives. (shrink)

Summary: The paper provides an argument for modal primitivism, the view that necessity is not defined and is therefore part of the structure of reality. It then raises the explanation-challenge for primitivists: how can modal truths be explained by hyper-intensional truths, if necessity is not defined in terms of hyper-intensional phenomena? To address the challenge, the paper introduces 'sophisticated modal primitivism' which gives a substantive analysis of the notion of a 'source of necessity'. The final part of the paper offers (...) some applications of that novel piece of ideology. (shrink)

Thomas Scanlon and Derek Parfit have recently defended a meta-ethical view that is supposed to satisfy realistic intuitions about morality, without the metaphysical implications that many find hard to accept in other realist views. Both philosophers argue that truths in the normative domain do not have ontological implications, while truths in the scientific domain presuppose a metaphysical reality. What distinguishes Scanlon and Parfit’s approach from other realistic meta-ethical theories is that they maintain that normative entities exist in a way that (...) is different from (some) non-normative entities. Moreover, they think that this view about the way normative entities exist helps to answer the metaphysical worries that are often thought to plague non-naturalism. To make sense of this idea, I develop their view as a version of alethic pluralism: the position that there is more than one truth property. I argue, however, that when their view is developed in this way it fails to satisfy realistic intuitions about morality. This shows that on a plausible and initially promising reading of what it takes for a normative entity to exist in a way that is different from non-normative entities, Parfit’s and Scanlon’s non-metaphysical moral realism fails to be more realistic than contemporary versions of anti-realism.

There are three theories in the epistemology of modality that have received sustained attention over the past 20 years: conceivability-theory, counterfactual-theory, and deduction-theory. In this paper we argue that all three face what we call the problem of modal epistemic friction. One consequence of the problem is that for any of the three accounts to yield modal knowledge, the account must provide an epistemology of essence. We discuss an attempt to fend off the problem within the context of the internalism (...) versus externalism debate about epistemic justification. We then investigate the effects that the PMEF has on reductive and non-reductive theories of the relation between essence and modality. (shrink)

Objective moral facts are supposed to be independent from us, but it has proven difficult to provide a clear account of this independence condition. Objective moral facts cannot be overly independent of us, as even an objective morality would depend, in important respects, on features of us. The challenge is to respect these moral mind-dependencies without inappropriately counting too many moral facts as objective. In this paper, I delineate and evaluate several different versions of the independence condition in moral objectivity. (...) I raise problems for these ways of formulating moral objectivity and then develop a better account of moral objectivity, one that avoids the pitfalls of other proposals. (shrink)

For C.S. Peirce, who had a well‐known influence on many aspects of Ramsey's thought, pragmatism was viewed as inseparable from realism. The aim of this paper is to challenge the view according to which Ramsey's reflexions on universals are of a mere linguistic and logical nature. Not only is this view controversial, but it may be argued that some elements in Ramsey's analyses suggest a possibly realist answer to the problem of universals. By drawing comparisons with Peirce's own position, it (...) is suggested that Ramsey's views might not be inconsistent with many aspects of Peirce's scholastic and even Scotistic version of realism.

Despite the otherwise-dominant trends towards physicalism and naturalism in philosophy, it has become increasingly common for metaphysicians to accept the existence either of modal facts and properties, or of Lewisian possible worlds. This paper raises the historical question: why did these heavyweight realist views come into prominence? The answer is that they have arisen in response to the demand to find truthmakers for our modal statements. But this demand presupposes that modal statements are descriptive claims in need of truthmakers. This (...) presupposition was, however, rejected by many earlier analytic philosophers, including the logical positivists, Wittgenstein, Ryle and Sellars, all of whom denied that modal statement were descriptive at all. Yet the non-descriptivist approach has largely fallen out of discussion and out of philosophical consciousness. In this paper I examine why non-descriptivist views first came into and then fell out of favor, and consider what the prospects are for reviving this more deflationary approach to modality. (shrink)

If the bindingness of morality was to rest on something as ‘subjective’ as the non-cognitivist says it does, the grouse goes, and morality itself would come down crashing. Nothing less than an ‘objective’ source of normativity, it is supposed, could hold morality in orbit. Some of these worries automatically morph into worries about the projectivist model of normativity of law as well: one which understands the authority or normativity of law in terms of subjective attitudes taken towards the law. As (...) well as the stock worries about non-cognitivism, there are some additional ones that the projectivist model brings in its wake that it cannot account for the ‘uniform’ bindingness of law and that a subjective source of normativity of law based on mental states is unintelligible. This essay makes the case for acquitting the projectivist model of normativity of law from the above charges. But the route to that necessarily leads through first acquitt... (shrink)

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

Many philosophers think that normative judgements do not aim to represent the world. In this paper, I argue that this view is incompatible with the thought that when two people make conflicting normative judgements, at most one of these judgements is correct. I argue that this shows that normative judgements do aim to represent the world.

This chapter sketches four forms of realism ascribed to four great historical figures that provide an important set of determinate versions of moral realism. Plato provides a picture according to which moral facts exist in a non-concrete realm of abstract universal properties. Aristotle provides a picture according to which moral facts exist as concrete facts in the world. Hume provides a picture according to which moral facts have their basis in universal human sentiments. Kant provides a picture according to which (...) moral facts are simply truths of universal reason. It is argued that the revolution in our understanding of metaphysical explanations that occurred between Aristotle and Hume has important consequences for realist views. (shrink)

The modalities come into the world by being projections or objectivizations of our epistemic constitution. Thus this paper is a statement of Humean projectivism. In fact, it goes beyond Simon Blackburn’s version. It is also designed as a comprehensive counter-program to David Lewis’ program of Humean supervenience. In detail, the paper explains: Already the basic fact that the world is a world of states of affairs is due to the nature of our epistemic states. Objects, which figure in states of (...) affairs and which embody metaphysical modality, are constitutable by their essential properties and in fact constituted by us according to our ontological policies. What the facts are, to which the correspondence notion of truth refers, is determined by applying an epistemic or pragmatic notion of truth to the world. Causation is a specific objectivization of our conditional beliefs. Nomicity is a ‘habit of belief’, a specific way of generalizing epistemic attitudes. This covers the basic metaphysical and natural modalities. The paper attempts to convey that talking of projection or objectivization is not just imagery, but a constructively realizable program.

Should the responsibilities of business managers be understood independently of the social circumstances and “market forces”that surround them, or (in accord with empiricism and the social sciences) are agents and their choices shaped by their circumstances,free only insofar as they act in accordance with antecedently established dispositions, their “character”? Virtue ethics, of which I consider myself a proponent, shares with empiricism this emphasis on character as well as an affinity with the social sciences. But recent criticisms of both empiricist and (...) virtue ethical accounts of character deny even this apparent compromise between agency and environment. Here is an account of character that emphasizes dynamic interaction both in the formation and in the interplay between personal agency and responsibility on the one hand and social pressures and the environment on the other.

This paper applies the theory of teleosemantics to the issue of moral content. Two versions of teleosemantics are distinguished: input-based and output-based. It is argued that applying either to the case of moral judgements generates the conclusion that such judgements have both descriptive (belief-like) and directive (desire-like) content, intimately entwined. This conclusion directly validates neither descriptivism nor expressivism, but the application of teleosemantics to moral content does leave the descriptivist with explanatory challenges which the expressivist does not face. Since teleosemantics (...) ties content to function, the paper also offers an account of the evolutionary function of moral judgements. (shrink)

This paper examines the prospects for a conceptual or functional role theory of moral concepts. It is argued that such an account is well-placed to explain both the irreducibility and practicality of moral concepts. Several versions of conceptual role semantics for moral concepts are distinguished, depending on whether the concept-constitutive conceptual roles are wide or narrow normative or non-normative and purely doxastic or conative. It is argued that the most plausible version of conceptual role semantics for moral concepts involves only (...) ‘narrow’ conceptual roles, where these include connections to motivational, desire-like, states. In the penultimate section it is argued, contrary to what Wedgwood, Enoch and others have claimed, that such an account of moral concepts cannot plausibly be combined with the claim that moral concepts refer to robust properties.

In this paper I discuss the so-called problem of creeping minimalism, the problem of distinguishing metaethical expressivism from its rivals once expressivists start accepting minimalist theories about truth, representation, belief, and similar concepts. I argue that Dreier’s ‘explanation’ explanation is almost correct, but by critically examining it we not only get a better solution, but also draw out some interesting results about expressivism and non-representationalist theories of meaning more generally.

Argues that, in acting for a reason, one takes that reason to explain one's action, not to justify it: reasons for acting need not be seen "under the guise of the good". The argument turns on the need to explain the place of "practical knowledge" - knowing what one is doing - in intentional action. A revised and expanded version of this material appears in Part One of "Reasons without Rationalism" (Princeton, 2007).

Expressivism’s central idea is that normative sentences bear the same relation to non-cognitive attitudes that ordinary descriptive sentences bear to beliefs: the expression relation. Allan Gibbard teIls us that “that words express judgments will be accepted by almost everyone” - the distinctive contribution of expressivism, his claim goes, is only a view about what kind of judgments words express. But not every account of the expression relation is equally suitable for the expressivist’s purposes. In fact, what I argue in this (...) paper, considering four possible accounts of expression, is that how suitable each account is for the expressivist’s purpose varies in proportion to how controversial it is. So Gibbard is wrong - if expression is to get expressivism off the ground, then it will be enormously controversial whether words do express judgments. And thus expressivism is committed to strong claims about the semantics of non-normative language. (shrink)

This paper is a critique of Ralph Wedgwood's recent attempt to use the framework of conceptual role semantics in metaethics. Wedgwood's central idea is that the action-guiding role of moral terms suffices to determine genuine properties as their semantic values. We argue that Wedgwood cannot get so much for so little. We explore two interpretations of Wedgwood's account of what it takes to be competent with a thin moral term. On the first interpretation, the account does not warrant the assignment (...) of a normative property as the semantic value of the target expression. On the second interpretation, the account presupposes that the subject has a prior understanding of normative notions. (shrink)

The claim that God is perfectly beautiful has played a key role within the history of a number of religious traditions. However, this view has received surprisingly little attention from philosophers of religion in recent decades. In this article I aim to remedy this neglect by addressing some key philosophical issues surrounding the doctrine of divine beauty. I begin by considering how best to explicate the claim that God is perfectly beautiful before moving on to ask what consequences accepting this (...) claim will have for our broader theorizing in philosophy.

Quasi-realists aspire to accommodate core features of ordinary normative thought and discourse in an expressivist framework. One apparent such feature is that we can be more or less confident in our normative judgments—they vary in credence. Michael Smith has argued that quasi-realists cannot plausibly accommodate these distinctions simply because they understand normative judgments as desires, but desires lack the structure needed to distinguish these three features. Existing attempts to meet Smith’s challenge have accepted Smith’s presupposition that the way to meet (...) the challenge is to show that normative judgments have more structure than they initially seem to have. I argue that accepting this presupposition is accepting too much. The orthodox view of certitude, insofar as there is one, understands certitude very roughly in terms of counterfactual betting behaviour. Counterfactual betting behaviour, though, is not in any useful sense a structural feature of a given judgment. It is rather a more holistic feature of a given agent’s cognitive system. Insofar as it can meet the other challenges it faces, quasi-realism can characterize credences in terms of counterfactual betting behaviour and effectively say exactly what many realists will want to say about credences, thus meeting Smith’s challenge much more directly.

Moral realism and antirealist-expressivism are of course incompatible positions. They disagree fundamentally about the nature of moral states of mind, the existence of moral states of affairs and properties, and the nature and role of moral discourse. The central realist view is that a person who has or expresses a moral thought is thereby in, or thereby expresses, a cognitive state of mind; she has or expresses a belief that represents a moral state of affairs in a way that might (...) be accurate or inaccurate. The view of antirealist-expressivism is that such a person is in, or expresses, a conative state of mind, one that consists in a certain kind of attitude or motivational stance toward something, such as an action or a person. Realism holds that moral thoughts have truth conditions and that in some cases these truth conditions are satisfied so that our moral thoughts are true. Antirealist-expressivism holds, to a first approximation, that the distinctive moral content of a moral thought does not have truth conditions. (shrink)

In the literature seeking to explain concepts in terms of their point, talk of ‘the point’ of concepts remains under-theorised. I propose a typology of points which distinguishes practical, evaluative, animating, and inferential points. This allows us to resolve tensions such as that between the ambition of explanations in terms of the points of concepts to be informative and the claim that mastering concepts requires grasping their point; and it allows us to exploit connections between types of points to understand (...) why they come apart, and whether they do so for problematic ideological reasons or for benignly functional reasons.

In this paper, I defend the view that the values of concrete objects and persons are reducible to the final values of tropes. This reductive account has recently been discussed and rejected by Rabinowicz and Rønnow-Rasmussen (2003). I begin by explaining why the reduction is appealing in the first place. In my rejoinder to Rabinowicz and Rønnow-Rasmussen I defend trope-value reductionism against three challenges. I focus mainly on their central objection, that holds that the reduction is untenable since different evaluative (...) attitudes have, ontologically speaking, different objects. I grant that this may well be so, but argue that the objection is based on an unwarranted, loose reading of the notion 'value for its own sake'. On the more reasonable strict reading, it is plausible to maintain that tropes are the sole ontological category that can properly be ascribed final value. (shrink)

I distinguish two different arguments against cognitivism in Bernard Williams’ writings on moral dilemmas. The first turns on there being a truth of the matter about what we ought to do in moral a dilemma. That argument can be met by appealing to our epistemic shortcomings and to pro tanto obligations. However, those responses make no headway with the second argument which concerns the rationality of the moral regret that we feel in dilemma situations. I show how the rationality of (...) moral regret can be explained on an ‘independent desire’ model. And I show how Williams’ second argument only appears to have force because of a certain faulty way of conceiving of the issue over cognitivism. But Williams’ argument rightly alerts us to the rational role of desire in our moral thought. (shrink)

Putnam has given a different twist to the ethical issues in his philosophical writing on ethics. In his book on ‘Ethics Without Ontology,’ he has given the different interpretation to the ethical issues. Putnam states that there is no ‘ontology’ in ethics. For him, there is nothing wrong with ethics, rather there is something wrong with metaphysics. The ethics cannot be justified from a non-ethical standpoint of view. In this way, Putnam challenges both inflationary ontological ethics and deflationary ontological ethics (...) and he bids goodbye to all varieties of ontologies. This idea of ethics goes against the possibility of Vedanta, Buddhism, Aristotelian metaphysics, Platonic forms, Islam, Kantian category, Levinas’s ‘being’, and Heidegger’s ontology. He replaced ‘ethical ontology’ with that of pragmatic pluralism: the recognition that we employ in our everyday lives different kinds of discourses, discourses subject to different standards and possessing different sorts of applications that all contribute to the description of reality. Putnam is right in many of his criticisms of metaphysical ethics, but it is not clear how he can avoid the idea of absolute values, which are transcendental as proposed by Wittgenstein. Wittgenstein accepts both aspects of ethical life, i.e., transcendental and empirical. I shall try to show that we have every reason to accept Wittgenstein’s view that there is ontology in ethics.

I assume that there exists a general phenomenon, the phenomenon of the explanatory gap, surrounding consciousness, normativity, intentionality, and more. Explanatory gaps are often thought to foreclose reductive possibilities wherever they appear. In response, reductivists who grant the existence of these gaps have offered countless local solutions. But typically such reductivist responses have had a serious shortcoming: because they appeal to essentially domain-specific features, they cannot be fully generalized, and in this sense these responses have been not just local but (...) parochial. Here I do better. Taking for granted that the explanatory gap is a genuine phenomenon, I offer a fully general diagnosis that unifies these previously fragmented reductivist responses. (shrink)

G. E. Moore famously argued against skepticism and idealism by appealing to their inconsistency with alleged certainties, like the existence of his own hands. Recently, some philosophers have offered analogous arguments against revisionary views about ethics such as metaethical error theory. These arguments appeal to the inconsistency of error theory with seemingly obvious moral claims like “it is wrong to torture an innocent child just for fun.” It might seem that such ‘Moorean’ arguments in ethics will stand or fall with (...) Moore’s own arguments in metaphysics and epistemology, in virtue of their shared structure. I argue that this is not so. I suggest that the epistemic force of the canonical Moorean arguments can best be understood to rest on asymmetries in indirect evidence. I then argue that this explanation suggests that Moorean arguments are less promising in ethics than they are against Moore’s own targets. I conclude by examining the competing attempt to vindicate Moorean arguments by appealing to Rawls’s method of reflective equilibrium. (shrink)

I describe a number of views in which metaphysical fundamentality is accounted for in normative terms. After describing many different ways this key idea could be developed, I turn to developing the idea in one specific way. After all, the more detailed the proposal, the easier it is to assess whether it works. The rough idea is that what it is for a property to be fundamental is for it to be prima facie obligatory to theorize in terms of that (...) property. (shrink)

The purpose of this paper is twofold: first we outline a version of non‐descriptivism, ‘minimal expressivism’, leaving aside certain long‐standing problems associated with conventional expressivist views. Second, we examine the way in which familiar expressivist results can be accommodated within this framework, through a particular interpretation that the expressive realm lends to a theory of meaning. Expressivist theories of meaning address only a portion of the classical problems attributed to this position when they seek to explain why the expressions they (...) deal with have a given meaning. A position can nevertheless be termed ‘expressivist’ – in the minimal sense that we favor – based simply on the following key features of the meaning of these expressions: they can be used as functions of propositions, and they are not used to describe the way the world is.

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.

One striking contrast that Kant draws between the kind of cognitive capacities that humans have and alternative kinds of intellect concerns modal concepts.

A number of philosophers in recent years have maintained that H. L. A. Hart in The Concept of Law propounded an expressivist account of the semantics of the legal statements that are uttered from the internal viewpoint of the people who run the institutions of legal governance in any jurisdiction. Although the primary aim of this article is to attack the attribution of that semantic doctrine to Hart, the article will begin with some metaphysical matters—the matters of reductionism and naturalism—that (...) often lie behind the development of expressivist approaches to the semantics of normative discourse. After briefly exploring those metaphysical concerns (to which I will return later), the article will begin its main discussion by rehearsing the distinction between the semantics and the pragmatics of utterances. It will then delineate the doctrine of expressivism which the aforementioned philosophers have in mind when they ascribe that doctrine to Hart. Although I will make reference to a few such philosophers, I will focus chiefly on an article by Kevin Toh that has been the fountainhead of all the subsequent attributions of expressivism to Hart. As will be argued herein, Toh and like‐minded philosophers have gone astray in imputing to Hart a semantic version of expressivism. Notwithstanding that Hart’s theory of law can aptly be characterized as expressivist, that characterization is appropriate only when expressivism is understood as an account of the pragmatics of legal statements rather than as an account of their semantics.

In this article, I expound and defend an interpretation of Sellars as a metaethical quasi-realist. Sellars analyzes moral discourse in non-cognitivist terms: in particular, he analyzes “ought”-statements as expressions of collective intentions deriving from a collective commitment to provide for the general welfare. But he also endorses a functional-role theory of meaning, on which a statement’s meaning is grounded in its being governed by semantical rules concerning language entry, intra-linguistic, and language departure transitions, and a theory of truth as correct (...) assertibility relative to such semantical rules. On these non-representationalist theories, even though moral statements are expressions of intentions and not fundamentally descriptive, they nevertheless count as assertorically meaningful, and some count as positively true. I further argue that this interpretation is capable not only of explaining Sellars’ explicitly metaethical writings, but also of unifying his scientific realism with his commitment to the ineliminable and indispensable role of the language of intentions: if this linguistic framework does not play an explanatory role, but only an expressive role, this explains both why Sellars’ commitment to it does not contravene his naturalism, as well as why, given the necessity of such language for our practical engagement with the world, the scientific image of humans in the world will only be completed once such language supplements it to enable us to relate practically to it.
