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.

This paper seeks to utilize mathematical methods to formally define and analyze the metaethical theory that is ethical reductionism. In contemporary metaethics, realist-antirealist debates center on the ontology of moral properties. Our research reflects an innovative methodology using methods from Graph Theory to clarify a debated position of Meta-Ethics, previously encumbered by intrinsic vagueness and ambiguity. We employ rigorous mathematical formalism to symbolize, parse, and thus disambiguate, particular philosophical questions regarding ethical ontological materialism of the reductionist variety. In this paper, (...) we seek to revisit the once vexed question regarding the multiple-realizability of moral properties by employing the mathematical machinery of hypergraphs and category theory. The utilization of Mathematical formalism offers explanatory flexibility specifically to the hypothesis that there are potentially an infinite number of unrelated subvening facts which may constitute supervening moral properties. We by no means have attempted to settle the argument on the side of naturalism, but have only identified an obstacle to rigorous argumentation, and pioneered a method to eliminate it. We hope our research will be of interest to both the Analytic Philosophy and the Applied Mathematics communities, and will help facilitate discussions of metaethics, particularly pertaining to ethical naturalism. We believe there is much research yet to be done. (shrink)

This paper defends pro-realism, the view that it is better if moral realism is true rather than any of its rivals. After offering an account of philosophical angst, I make three general arguments. The first targets nihilism: in securing the possibility of moral justification and vindication in objecting to certain harms, moral realism secures something that is non-morally valuable and even essential to the meaning and intelligibility of our lives. The second argument targets antirealism: moral realism secures a desirable independence (...) for moral justification that is qualitatively different from the anti-realistic construal of independence that is only explicable in terms of degrees of distance from our subjective responses and attitudes. Finally, I argue that while the pan-expressivist semantic program of quasi-realism has significant effects on what can be appropriately said in meta-ethical discourse, it provides no comfort to the pro-realist who is already angsty about anti-realism.

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)

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.

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.

The paper describes the problem for robust moral realism of explaining the supervenience of the moral on the non-moral, and examines five objections to the argument: The moral does not supervene on the descriptive, because we may owe different obligations to duplicates. If the supervenience thesis is repaired to block, it becomes trivial and easy to explain. Supervenience is a moral doctrine and should get an explanation from within normative ethics rather than metaethics. Supervenience is a conceptual truth and should (...) be explained by the nature of our concepts rather than by a metaphysical theory. The moral does not supervene on the descriptive, because moral principles are not metaphysically necessary. It concludes that none of these objections is successful, so Robust Realists do have an explanatory debt to worry about. (shrink)

Tässä artikkelissa käsittelen Descartesin ikuisten totuuksien välttämättömyyteen liittyvää ongelmaa. Teoksessa Mietiskelyjä ensimmäisestä filosofiasta (1641–1642) Descartes nostaa esiin käsitteen ikuisista totuuksista, käyttäen esimerkkinään kolmiota. Kolmion muuttumattomaan ja ikuiseen luontoon kuuluu esimerkiksi, että sen kolme kulmaa ovat yhteenlaskettuna 180°. Se on totta kolmiosta, vaikka yhtään yksittäistä kolmiota ei olisi koskaan ollutkaan olemassa. Eräät ajattelemieni asioiden piirteet ovat siis Descartesin mukaan ajattelustani riippumattomia. Ikuisia totuuksia ovat ainakin matemaattiset ja geometriset tosiseikat sekä ristiriidan laki. Samoin Descartesin kuuluisa lause “ajattelen, siis olen” lukeutuu ikuisten totuuksien (...) joukkoon. Descartesin ikuiset totuudet olisivatkin siis loogisesti välttämättömiä. Niillä on kyseinen olemus riippumatta ulkoisten kohteiden olemassaolosta tai siitä, ajattelenko niitä lainkaan. Kuitenkin kirjeenvaihdossaan Descartes pitää itsepintaisesti kiinni käsityksestään, että ikuiset totuudet ovat Jumalan vapaasti luomia ja Jumala olisi voinut luoda ne erilailla. Näin ollen luodut ikuiset totuudet eivät tarkkaan ottaen olisikaan välttämättömiä vaan kontingentteja. Ne voisivat olla myös toisella tavalla. Artikkelin alkuun esittelen Descartesin modaalista metafysiikkaa sekä luotujen ikuisten totuuksien kontingenttiudesta seuraavia tulkinnallisia vaikeuksia. Tämän jälkeen pureudun kolmeen erilaiseen ratkaisuyritykseen kommentaarikirjallisuudessa (Frankfurt 1977; Curley 1984 & Bennett 1994) ja osoitan, miksi ne eivät riitä vastaamaan ongelmaan. Lopussa vedän johtopäätöksiä ja luonnostelen mahdollisen ratkaisun. (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)

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.

There has been a great deal of discussion in the recent philosophical literature of the relationship between the minimalist theory of truth and the expressivist metaethical theory. One group of philosophers contends that minimalism and expressivism are compatible, the other group contends that such theories are incompatible. Following Simon Blackburn (manuscript), I will call the former position ‘compatibilism’ and the latter position ‘incompatiblism.’ Even those compatibilist philosophers who hold that there is no conflict or tension between these two theories—minimalism and (...) expressivism—typically think that some revision of minimalism is required to accommodate expressivism. The claim that there is such an incompatibility, I will argue, is based on a misunderstanding of the historical roots of expressivism, the motivations behind the expressivist theory, and the essential commitments of expressivism. I will present an account of the expressivist theory that is clearly consistent with minimalism. (shrink)

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (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. (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)

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)

Are there such things as moral truths? How do we know what we should do? And does it matter? Constructivism states that moral truths are neither invented nor discovered, but rather are constructed by rational agents in order to solve practical problems. While constructivism has become the focus of many philosophical debates in normative ethics, meta-ethics and action theory, its importance is still to be fully appreciated. These new essays written by leading scholars define and assess this new approach in (...) ethics, addressing such questions as the nature of constructivism, how constructivism improves our understanding of moral obligations, how it accounts for the development of normative practices, whether moral truths change over time, and many other topics. The volume will be valuable for advanced students and scholars of ethics and all who are interested in questions about the foundation of morality. (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.

Creeping minimalism threatens to cloud the distinction between realist and anti-realist metaethical views. When anti-realist views equip themselves with minimalist theories of truth and other semantic notions, they are able to take on more and more of the doctrines of realism (such as the existence of moral truths, facts, and beliefs). But then they start to look suspiciously like realist views. I suggest that creeping minimalism is a problem only if moral realism is understood primarily as a semantic doctrine. I (...) argue that moral realism is better understood instead as a metaphysical doctrine. As a result, we can usefully regiment the metaethical debate into one about moral truthmakers: in virtue of what are moral judgments true? I show how the notion of truthmaking has been simmering just below the surface of the metaethical debate, and how it reveals one metaethical view (quasi-realism) to be a stronger contender than the others.

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)

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..

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.

Many areas of philosophy employ a distinction between factual and non-factual (descriptive/non-descriptive, cognitive/non-cognitive, etc) uses of language. This book examines the various ways in which this distinction is normally drawn, argues that all are unsatisfactory, and suggests that the search for a sharp distinction is misconceived. The book develops an alternative approach, based on a novel theory of the function and origins of the concept of truth. The central hypothesis is that the main role of the normative notion of truth (...) is to encourage speakers to argue, with long-run behavioural advantages. This offers a fresh perspective on many debates about realism in contemporary philosophy. (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 1971, Simon Blackburn worked out an argument against moral realism appealing to the supervenience of the moral realm on the natural realm.1 He has since revised the argument, in part to take account of objections,2 but the basic structure remains intact. While commentators3 seem to agree that the argument is not successful, they have not agreed upon what goes wrong. I believe this is because no attempt has been made to see what happens when Blackburn's argument is addressed to (...) particular varieties of moral realism. As I see it, we must look to these various brands if we want to understand just where the concept of supervenience can be usefully employed. (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)

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)

A lot of people believe that distinct objects can occupy precisely the same place for the entire time during which they exist. Such people have to provide an answer to the 'grounding problem' – they have to explain how such things, alike in so many ways, nonetheless manage to fall under different sortals, or have different modal properties. I argue in detail that they cannot say that there is anything in virtue of which spatio-temporally coincident things have those properties. However, (...) I also argue that this may not be as bad as it looks, and that there is a way to make sense of the claim that such properties are primitive. (shrink)

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.

My aim is to challenge recent attempts at reconciling moral realism and naturalism by pushing ethical naturalists into a dilemma. According to one horn of the dilemma, ethical naturalists must either build unique facts and properties about divergent social structures into their subvenient sets of natural facts and properties, and so jeopardize the objectivity of moral truths, or insist, in the face of all possible worlds in which people have different moral beliefs than ours, that they are all mistaken—this despite (...) the fact that the belief-forming mechanism responsible for their moral beliefs was never concerned with the truth of those beliefs in the first place. This will bring me to suggest that moral properties might only weakly supervene upon natural phenomena. But, according to the other horn of the dilemma, weak supervenience is a defeater for moral knowledge. (shrink)

Blackburn’s “quasi-realism” aims to show that expressivism can accommodate the sorts of claims about moral truth, facts, objectivity, and the like that are found in ordinary moral thought and discourse. Egan argues that expressivists cannot accommodate certain claims about the possibility that one’s own fundamental moral commitments are mistaken. He criticizes what I call the approved change strategy, which explains that judgment in terms of the belief that one might change one’s mind as a result of favored processes such as (...) getting more information. Egan targets a simple version of that strategy; I raise objections to a more sophisticated expressivist alternative. I argue against Horgan and Timmons’ claim that quasi-realists need not accommodate certain thoughts about moral fallibility on the grounds that they are metaethical rather than first-order moral claims, and that the implied orientation toward others that results is not objectionably smug. I also argue that the sophisticated strategy problematically commits the expressivist to an ideal observer or advisor theory in first-order ethics. (shrink)

Supervenience in metaethics is the notion that there can be no moral dif-ference between two acts, persons or events without some non-moral difference underlying it. If St. Francis is a good man, there could not be a man exactly like St. Francis in non-evaluative respects that is not good. The phenomenon was first systematically discussed by R. M. Hare (1952), who argued that realists about evaluative properties struggle to account for it. As is well established, Hare, and following him, Simon (...) Blackburn, mistakenly took the relevant phenomenon to be weak rather than strong supervenience, and the explanations they offered for it are accordingly outdated. In this paper, I present a non-factualist account of strong su-pervenience of the evaluative and argue that it fares better than compet-ing realist views in explaining the conceptual nature of the phenomenon, as well as in offering an account of the supervenience of the evaluative in general, rather than more narrowly the moral. While Hare and Blackburn were wrong about the specifics, they were right in that non-factualists can offer a plausible account of the supervenience of the evaluative, that in certain respects is superior to competing realist explanations.

I argue that Jonas Olson’s argument from irreducible normativity is not a secure basis for an argument for error theory (section 1) 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 (section 2). 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 (but do not pursue) possible response strategies for expressivists (section 3). 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 (section 4).

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)

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.

The paper aims at meeting Blackburn’s challenge to explain the non-reductive supervenience of moral predicates on natural ones. It offers a critical examination of Hare’s model of moral thinking which can be used as a candidate for such an explanation. It is argued that, as it stands, Hare’s model fails to meet Blackburn’s challenge. Yet some revisions of the model are suggested, and it is claimed that the improved version does supply the required explanation. The model suggested in the paper (...) carries a meta-ethical implication concerning the superiority of the anti-realist understanding of moral discourse. (shrink)

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.

This thesis examines the little-known phenomenological ethical theory of Max Scheler, discussed in his Formalism in Ethics and Non-Formal Ethics of Values and The Nature of Sympathy, also bringing in various other complementary philosophers. It argues that Scheler’s theory, when supplemented with complementary ideas, is superior to those offered by contemporary analytic intuitionism and other meta-ethical theories. It argues that a theory of pluralist emotive intuitionism provides a better description of both our experience of ethical value and the logical requirements (...) for the ethical knowledge presumed by that experience. This thesis places Scheler’s theory in the context of ethical intuitionism up until the present. It considers why intuitionism has been generally rejected, looking at outstanding philosophical questions facing ethical intuitionism and previous attempted answers, and discussing current theories of analytic ethical intuitionism and their flaws. It explains the significant elements of Scheler’s ethical theory and how it can be understood in its phenomenological context. To demonstrate how Scheler’s material intuitionism is better than current theories of rationalist intuitionism, and other meta-ethical alternatives, this thesis looks at two main groups of issues. Firstly, the epistemological issues raised by Scheler’s theory and how it offers a possible solution to the problem of ethical knowledge, along with a brief consideration of ontological issues. Secondly, normative issues raised by Scheler’s theory: major issues on normative judgement raised but not answered by Scheler’s theory and, following this, a chapter dedicated to Scheler’s theory of ‘persons’, particularly with reference to Emmanuel Levinas. It concludes that an adapted Scheleran theory of ethical intuitionism can be superior to contemporary theories. It explains how the fundamental features of ethical experience may be epistemologically and phenomenologically justified based on objective values. It provides better responses to standard problems raised against intuitionism while also providing a natural explanation for a wider range of moral phenomena than standard meta-ethical alternatives. This demonstrates its superior explanatory power and provides strong arguments for its value as an over-arching meta-ethical theory. (shrink)

Our project in this essay is to showcase nonnaturalistic moral realism’s resources for responding to metaphysical and epistemological objections by taking the view in some new directions. The central thesis we will argue for is that there is a battery of substantive moral propositions that are also nonnaturalistic conceptual truths. We call these propositions the moral fixed points. We will argue that they must find a place in any system of moral norms that applies to beings like us, in worlds (...) similar to our own. By committing themselves to true propositions of these sorts, nonnaturalists can fashion a view that is highly attractive in its own right, and resistant to the most prominent objections that have been pressed against it.

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.

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)

Blackburn argues that moral supervenience in conjunction with the lack of entailments from naturalistic to moral judgments poses a challenge to moral realism. Klagge and McFetridge try to avert the challenge by appealing to synthetically necessary connections between natural and moral properties. Blackburn rejoins that, even if there are such connections, the challenge still remains. We remain agnostic on the question whether there are such connections, but argue against Blackburn that, if there are indeed such connections, then the challenge to (...) moral realism, properly phrased, does not hold up.

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)

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.
