The thesis that mental properties are dependent, or supervenient, on physical properties, but this dependence is not lawlike, has been influential in contemporary philosophy of mind. It is put forward explicitly in Donald Davidson's seminal ‘Mental Events.’ On the one hand, Davidson claims that the mental is anomalous, that ‘there are no strict deterministic laws on the basis of which mental events can be predicted and explained’, and, in particular, that there are no strict psychophysical laws. On the other hand, (...) he insists that the mental supervenes on the physical; that ‘mental characteristics are in some sense dependent, or supervenient, on physical characteristics’. (shrink)

Presenting the first comprehensive, in-depth study of hyperintensionality, this book equips readers with the basic tools needed to appreciate some of current and future debates in the philosophy of language, semantics, and metaphysics. After introducing and explaining the major approaches to hyperintensionality found in the literature, the book tackles its systematic connections to normativity and offers some contributions to the current debates. The book offers undergraduate and graduate students an essential introduction to the topic, while also helping professionals in related (...) fields get up to speed on open research-level problems.

In his paper "Supervenience Revisisted", Simon Blackburn redeployed his novel modal argument against moral realism as an argument against Donald Davidson's position of 'anomalous monism' in the philosophy of mind (Blackburn 1985).' I shall assess this redeployment. In the first part of this paper, I shall lay out Blackburn's argument. In the second and longer part I shall examine Davidson's denial of psychophysical laws in the light of this argument.

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)

The morality of virtual representations and the enactment of prohibited activities within single-player gamespace continues to be debated and, to date, a consensus is not forthcoming. Various moral arguments have been presented to support the moral prohibition of virtual enactments, but their applicability to gamespace is questioned. In this paper, I adopt a meta-ethical approach to moral utterances about virtual representations, and ask what it means when one declares that a virtual interaction ‘is morally wrong’. In response, I present constructive (...) ecumenical expressivism to explain what moral utterances should be taken to mean, argue that they mean the same when referring to virtual and non-virtual interactions and, given, explain why consensus with regard to virtual murder, rape and paedophilia is not forthcoming even though such consensus is readily found with regard to their non-virtual equivalents.

David Brink has recently argued for the “parity” of ethics and the sciences. While the parity claim alone might be metaphysically neutral, Brink favours a form of ethical naturalism on which moral properties “are” natural properties, just as non-moral macrophysical properties “are” the microphysical states that compose them. Brink supports this claim by showing that both types of properties share certain important features: specifically, that both may be constituted, supervening and synthetically necessitated. I shall argue that notwithstanding these common features, (...) there remain significant modal differences in the way the two types of properties are assigned to the world. These differences represent an important respect in which moral properties are not on par with their scientific counterparts. (shrink)

Mooreans claim that intrinsic goodness is a conceptual primitive. Fitting-attitude theorists object: they say that goodness should be defined in terms of what it is fitting for us to value. The Moorean view is often considered a relic; the fitting-attitude view is increasingly popular. I think this unfortunate. Though the fitting-attitude analysis is powerful, the Moorean view is still attractive. I dedicate myself to the influential arguments marshaled against Moore’s program, including those advanced by Scanlon, Stratton-Lake and Hooker, and Jacobson; (...) I argue that they do not succeed.

I argue that Jonas Olson’s argument from irreducible normativity is not a secure basis for an argument for error theory and that a better basis is provided by the argument from supervenience, which has more bite against non-naturalist moral realism than Olson is willing to allow. I suggest there may be a view which can allow for the existence of irreducibly normative facts while remaining unaffected by the kinds of arguments that work against non-naturalist realism. This view is expressivism. Interestingly, (...) James Dreier has recently suggested that expressivism may not escape these arguments. I very briefly outline possible response strategies for expressivists. I close by discussing Olson’s argument against expressivism. Olson suggests, somewhat surprisingly, that expressivism is a bad fit with a plausible evolutionary explanation of our moral thought. I argue that Olson’s argument does not succeed. (shrink)

If I say “we are now living in England” or “grass is green in summer’ or ‘the cat is on the mat’ what I say will normally be true or false—the statements are true if they correctly report how things are, or correspond to the facts; and if they do not do these things, they are false. Such a statement will only fail to have a truth-value if its referring expressions fail to refer ; or if the statement lies on (...) the border between truth and falsity so that it is as true to say that the statement is true as to say that it is false. Are moral judgments normally true or false in the way in which the above statements are true or false? I will term the view that they are objectivism and the view that they are not subjectivism. The objectivist maintains that it is as much a fact about an action that it is right or wrong as that it causes pain or takes a long time to perform. The subjectivist maintains that saying than an action is right or wrong is not stating a fact about it but merely expressing approval of it or commending it or doing some such similar thing. I wish in this paper, first, to show that all arguments for subjectivism manifestly fail, and secondly to produce a strong argument for objectivism. But, to start with, some preliminaries. (shrink)

This chapter offers an introduction to naturalist views in contemporary metaethics. Such views attempt to find a place for normative properties (such as goodness and rightness) in the concrete physical world as it is understood by both science and common sense. The chapter begins by introducing simple naturalist conceptual analyses of normative terms. It then explains how these analyses were rejected in the beginning of the 20th Century due to G.E. Moore’s influential Open Question Argument. After this, the chapter considers (...) what good general reasons there are for defending naturalism in metaethics. The bulk of the chapter will then survey new semantic and metaphysical forms of naturalism which in different ways attempt to address Moore’s objection to naturalism. These more recent versions of naturalism—using new resources from philosophy of language, philosophy of mind, metaphysics, philosophy of science and epistemology—attempt to explain why the Open Question Argument fails.

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.

This paper develops a view on which: (a) all fundamental facts are absolute, (b) some facts do not supervene on the fundamental facts, and (c) only relative facts fail to supervene on the fundamental facts.

Moral properties would supervene upon non-moral properties and be conceptually autonomous. That, according to Simon Blackburn, would make them if not impossible at least mysterious, and evidence for them best explained by theorists who say they are not real. In fact moral properties would not challenge in ways Blackburn has contended. There is, however, something new that can be gathered from his arguments. What would the supervenience of moral properties and their conceptual autonomy from at least total non-moral properties entail (...) not only for Intuitionists, who ‘knew this all along,’ but for all moral realists, that there are synthetic necessary moral principles? There is for all moral realists the problem of explaining ‘what in the world’ makes possible these necessities. (shrink)

Contrary to popular opinion, non-natural realism can explain both why normative properties supervene on descriptive properties, and why this pattern is analytic. The explanation proceeds by positing a subtle polysemy in normative predicates like “good”. Such predicates express slightly different senses when they are applied to particulars (like Florence Nightingale) and to kinds (like altruism). The former sense, “goodPAR”, can be defined in terms of the latter, “goodKIN”, as follows: x is goodPAR iff there is a kind K such that (...) x is a token of K, and K is goodKIN. Now if x and y are descriptively exactly similar, then they are tokens of exactly the same kinds, so x is a token of a goodKIN kind if and only if y is. Therefore, by the definition, x is goodPAR if and only if y is. Supervenience just falls out of the definition of “goodPAR”. (shrink)

This paper defends moral realism against Sharon Street’s “Darwinian Dilemma for Realist Theories of Value” (this journal, 2006). I argue by separation of cases: From the assumption that a certain normative claim is true, I argue that the first horn of the dilemma is tenable for realists. Then, from the assumption that the same normative claim is false, I argue that the second horn is tenable. Either way, then, the Darwinian dilemma does not add anything to realists’ epistemic worries.

Moral discourse is propositionally clothed, that is, it exhibits those features – such as the ability of its sentences to intelligibly embed in conditionals and other unasserted contexts – that have been taken by some philosophers to be constitutive of discourses that express propositions. If there is nothing more to a mental state being a belief than it being characteristically expressed by sentences that are propositionally clothed then the version of expressivism which accepts that moral discourse is propositionally clothed (‘quasi-realism’) (...) is self-refuting. Fortunately for quasi-realists, this view of belief, which I label ‘minimalism’, is false. I present three arguments against it and dismiss two possible defences (the first drawn from the work of Wright, the second given by Harcourt). The conclusion is that the issue between expressivists and their opponents cannot be settled by the mere fact that moral discourse wears propositional clothing. (shrink)

This paper advances three necessary conditions on a successful account of sentential negation. First, the ability to explain the constancy of sentential meaning across negated and unnegated contexts (the Fregean Condition). Second, the ability to explain why sentences and their negations are inconsistent, and inconsistent in virtue of the meaning of negation (the Semantic Condition). Third, the ability of the account to generalize regardless of the topic of the negated sentence (the Generality Condition). The paper discusses three accounts of negation (...) available to moral expressivists. The first—the dominant commitment account—fails to meet the Fregean Condition. The two remaining accounts—commitment semantics and the expression account—satisfy all three conditions. A recent argument that the dominant commitment account is the only option available to expressivists is considered and rejected. (shrink)

Many expressivists have employed a claim about the practicality of morality in support of their view that moral convictions are not purely descriptive mental states. In this paper I argue that all extant arguments of this form fail. I distinguish several versions of such arguments and argue that in each case either the sense of practicality the argument employs is too weak, in which case there is no reason to think that descriptive states cannot be practical or the sense of (...) practicality the argument employs is too strong, in which case there is no reason to think moral convictions are practical. I also discuss and dismiss an attempted patch of such arguments provided by Humean Psychology. The conclusion is that expressivists need to look to sources other than the alleged practicality of morality to support their position. In concluding remarks I suggest one such alternative. (shrink)

In this paper I argue that the common practice of employing moral predicates as explaining phrases can be accommodated on an expressivist account of moral practice. This account does not treat moral explanations as in any way second-rate or derivative, since it subsumes moral explanations under the general theory of program explanations (as defended by Jackson and Pettit). It follows that the phenomenon of moral explanations cannot be used to adjudicate the debate between expressivism and its rivals.

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have also been (...) influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

Expressivists have a problem with negation. The problem is that they have not, to date, been able to explain why ‘murdering is wrong’ and ‘murdering is not wrong’ are inconsistent sentences. In this paper, I explain the nature of the problem, and why the best efforts of Gibbard, Dreier, and Horgan and Timmons don’t solve it. Then I show how to diagnose where the problem comes from, and consequently how it is possible for expressivists to solve it. Expressivists should accept (...) this solution, I argue, because it is demonstrably the only way of avoiding the problem, and because it generalizes. Once we see how to solve the negation problem, I show, it becomes easy to state a constructive, compositional expressivist semantics for a purely normative language with the expressive power of propositional logic, in which we can for the first time give explanatory, formally adequate expressivist accounts of logical inconsistency, logical entailment, and logical validity. As a corollary, I give what I take to be the first real expressivist explanation of why Geach’s original moral modus ponens argument is genuinely logically valid. This proves that the problem with expressivism cannot be that it can’t account for the logical properties of complex normative sentences. But it does not show that the same solution can work for a language with both normative and descriptive predicates, let alone that expressivists are able to deal with more complex linguistic constructions like tense, modals, or even quantifiers. In the final section, I show what kind of constraints the solution offered here would place expressivists under, in answering these further questions. (shrink)

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)

Metaethical expressivists claim that we can explain what moral words like ‘wrong’ mean without having to know what they are about – but rather by saying what it is to think that something is wrong – namely, to disapprove of it. Given the close connection between expressivists’ theory of the meaning of moral words and our attitudes of approval and disapproval, expressivists have had a hard time shaking the intuitive charge that theirs is an objectionably subjectivist or mind-dependent view of (...) morality. Expressivism, critics have charged over and again, is committed to the view that what is wrong somehow depends on or at least correlates with the attitudes that we have toward it. Arguments to this effect are sometimes subtle, and sometimes rely on fancy machinery, but they all share a common flaw. They all fail to respect the fundamental idea of expressivism: that ‘stealing is wrong’ bears exactly the same relationship to disapproval of stealing as ‘grass is green’ bears to the belief that grass is green. In this paper I rehearse the motivations for the fundamental idea of expressivism and show how the arguments of Frank Jackson and Philip Pettit [1998], Russ Shafer-Landau [2003], Jussi Suikkanen [2009], and Christopher Peacocke [2004] all fail on this same rock. In part 1 I’ll rehearse the motivation for expressivism – a motivation which directly explains why it does not have subjectivist consequences. Then in each of parts 2-5 I’ll illustrate how each of Jackson and Pettit’s, Peacocke’s, Shafer-Landau’s, and Suikkanen’s arguments work, respectively, and why each of them fails to respect the fundamental parity at the heart of expressivism. Though others have tried before me to explain why expressivism is not committed to any kind of subjectivism or mind-dependence – prominently including Blackburn [1973], [1998], Horgan and Timmons [2006], and, in response to Pettit and Jackson, Dreier [2004] and Smith and Stoljar [2003], the explanation offered in this article is distinguished by its scope and generality..

Autonomy and valuing are two significant practical phenomena that have been analysed in terms of higher-order wanting. I argue that reference to higher-order capacities is indeed required to make sense of both concepts, but also that such analyses need a more differentiated understanding of "wanting to want" than has hitherto been proposed. Central for autonomy is the instantiation of four types of optative relationship by an accountable agent under conditions of rationality. Valuing requires the disposition to instantiate only one of (...) the relevant structures. Clarity on this allows an analysis of the precise relationships between the two phenomena. (shrink)

What place, if any, moral principles should or do have in moral life has been a longstanding question for moral philosophy. For some, the proposition that moral philosophy should strive to articulate moral principles has been an article of faith. At least since Aristotle, however, there has been a rich counter-tradition that questions the possibility or value of trying to capture morality in principled terms. In recent years, philosophers who question principled approaches to morality have argued under the banner of (...) moral particularism. Particularists can be found in diverse areas of philosophical inquiry, and their positions and arguments are of broad interest.1 Despite its importance, a proper evaluation of particularism has been hindered both by the diversity of arguments employed to defend it, and, perhaps more significantly, by the diversity of positions that can fairly claim to be particularist. Our aim is first to explicate particularism by identifying a unified range of particularist theses and explaining both what unites them as versions of particularism as well as what distinguishes them from each other. We then articulate and evaluate the main arguments for particularism and explain how each is especially well-suited to supporting some conceptions of particularism rather than others. We tentatively conclude that the positive arguments for particularism are not convincing. They do, however, reveal particularism to be a surprisingly resilient position, one that is not readily refuted.. (shrink)

How, in pursuit of ontological neutrality, should one talk about values? I propose to say: there are values. Those three words do nothing to define within what kind of conception of a world values are at home.1 I take it that the ‘realist’ must have more to say about values and their world. I recognize that an ‘anti-realist’ may prefer to talk of value-terms ; I ask him to wait and see whether taking the linguistic turn is the only way (...) to put values in their place. (shrink)

Blackburn argues against naturalistic moral realism. He argues that there is no conceptual entailment from satisfying a naturalistic predicate to satisfying a moral predicate. But the moral is conceptually supervenient on the natural. However, this conjunction of conceptual supervenience with lack of conceptual entailment is something the non-realist can explain, but the realist cannot. I argue first that Blackburn’s best formulation of his challenge is his first one. Subsequently he reformulates it as a demand for a ‘ban on mixed worlds’. (...) Critics have directed their arguments against this formulation but they are ineffective against Blackburn’s first formulation. My second thesis is, even so formulated the realist can meet the challenge. The bare conceptual supervenience of the moral on the natural can be given a realist explanation by understanding names of moral properties as descriptive names of natural properties. (shrink)

I argue that all rights exist by convention. According to my definition, a right exists by convention just in case its justification appeals to the rules of a socially shared pattern of acting. I show that our usual justifications for rights are circular, that a right fulfills my criterion if all possible justifications for it are circular, and that all existing philosophical justifications for rights are circular or fail. We find three non-circular alternatives in the literature, viz. justifications of rights (...) by consequences, by autonomy or by divine commands. I show that all three alternatives fail, and I conclude that all rights exist by convention. This ontological result has a surprising and beneficial consequence. A common argument against conventionalism is that it implies cultural relativism. I finish by showing that the suggested conventionalism is incompatible with cultural relativism. (shrink)

Non-naturalists about normativity hold that there are instantiable normative properties which are metaphysically discontinuous with natural properties. One of the central challenges to non-naturalism is how to reconcile this discontinuity with the supervenience of the normative on the natural. Drawing on J. L. Mackie’s seminal but highly compressed discussion in Ethics: Inventing Right and Wrong, this paper argues that the supervenience challenge as usually conceived is merely a symptom of a more fundamental challenge in the vicinity.

Simon Blackburn’s supervenience argument—focusing on the mysterious “ban on mixed worlds”—is still subject to a variety of conflicting interpretations. In this paper, I hope to provide a defense of the argument that clarifies both the argument and the objections it must overcome. Many of the extant objections, I will argue, fail to engage the argument in its true form. And to counter the more compelling objections, it will be necessary to bring in additional argumentation that Blackburn himself does not clearly (...) provide. One important upshot of this discussion is that moral realism is not the only target of the argument: it raises trouble for a variety of metaethical views wed to realist-friendly construals of moral evaluation. Rightly understood, this argument not only survives the prominent responses, but turns out to be more powerful than his critics and Blackburn himself have recognized. (shrink)

One of the most familiar arguments for expressivist metaethics is the claim that the rival theory, moral realism, cannot provide a satisfying explanation of why moral properties supervene on natural properties. Non-cognitivism, however, has its own problems explaining supervenience. Expressivists try to establish supervenience either by second-order disapproval of type-inconsistent moral evaluations or by pragmatic considerations. But disapproval of inconsistency is merely a contingent attitude that people happen to have; and pragmatic justification does not allow for appraisers to take their (...) own moral attitudes seriously enough. What has been overlooked is a third alternative. The metaethical theory that can best account for supervenience is neither realist nor non-cognitivist but an objectivist version of constructivism. On the constructivist theory, right and wrong are determined by the principles that people would (hypothetically) consent to under ideal conditions. Type-consistency is a required feature of any principles regulating our conduct, if they are to be freely agreed to by ideally rational people. (shrink)

For some, the proposition that moral philosophy should strive to articulate moral principles has been an article of faith. At least since Aristotle, however, there has been a rieh counter-tradition that questions the possibility or value of trying to capture morality in principled terms.

Supervenience has provided a way for nonreductive materialists to explain how the mental can be physically irreducible but still physically respectable. In recent years, doubts about this research program have emerged from a number of quarters. Consequently, Terence Horgan has argued that nonreductive materialists must appeal to an upgraded "superdupervenience," if supervenience is to do any materialist work. We argue that nonreductive materialism cannot meet this challenge. Superdupervenience is impossible.

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.

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)

If, as expressivists maintain, the function of normative thought and talk is not to represent or describe the world, then how can normative judgements be correct or incorrect? In particular, how can I make sense of my own normative fallibility, the possibility that my own normative judgements might be mistaken? In this paper, I construct and defend a substantive but non-representational theory of normative (in)correctness for expressivists. Inspired by Blackburn’s (1998: 318) proposal that I make sense of my fallibility in (...) terms of the possibility that my judgements might be unstable through improvement, my account is designed in the first instance to vindicate the expressivist’s conception of the nature of normative inquiry. I then defend the proposal from the charge that it leaves insufficient room for my own fallibility, and in particular from Egan’s (2007) argument that it implies a “smug” asymmetry between myself and others. Critical to the response is the appeal to indeterminacy in cases of fundamental normative disagreement between reasonable normative outlooks. (shrink)
