This book is a systematic and constructive treatment of a number of traditional issues at the foundation of ethics, the possibility and nature of moral knowledge, the relationship between the moral point of view and a scientific or naturalistic world view, the nature of moral value and obligation, and the role of morality in a person's rational life plan. In striking contrast to many traditional authors and to other recent writers in the field, David Brink offers an integrated defense of (...) the objectivity of ethics. (shrink)

The central philosophical challenge of metaethics is to account for the normativity of moral judgment without abandoning or seriously compromising moral realism. In Morality in a Natural World, David Copp defends a version of naturalistic moral realism that can accommodate the normativity of morality. Moral naturalism is often thought to face special metaphysical, epistemological, and semantic problems as well as the difficulty in accounting for normativity. In the ten essays included in this volume, Copp defends solutions to these problems. Three (...) of the essays are new, while seven have previously been published. All of them are concerned with the viability of naturalistic and realistic accounts of the nature of morality, or, more generally, with the viability of naturalistic accounts of reasons. (shrink)

Since Hilary Putnam offered multiple realization as an empirical hypothesis in the 1960s, philosophical consensus has turned against the idea that mental processes are identifiable with brain processes, and multiple realization has become the keystone of the 'antireductive consensus' across philosophy of science. Thomas W. Polger and Lawrence A. Shapiro offer the first book-length investigation of multiple realization, which serves as a starting point to a series of philosophically sophisticated and empirically informed arguments that cast doubt on the generality of (...) multiple realization in the cognitive sciences. They argue that mind-brain identities have played an important role in the growth and achievements of the cognitive sciences, and suggest that there is little prospect for multiple realization in an empirically-based theory of mind. This leads Polger and Shapiro to offer an alternative framework for understanding explanations in the cognitive sciences, as well as in chemistry, biology, and other non-basic sciences. (shrink)

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ explains that the history (...) of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

Adams offers a theistically-based framework for ethics, based upon the idea of a transcendent, infinite good, which is God, and its relation to the many finite examples of good in our experience. His account shows how philosophically unfashionable religious concepts can enrich ethical thought.

According to proponents of one influential account of metaphysical naturalness, properties fall along a spectrum from perfectly natural to highly non-natural. The perfectly natural end of the spectrum is occupied by properties that appear in the laws of nature, account for resemblance and causal powers, and ground other properties, whereas the highly non-natural properties at the spectrum’s other end are not like this at all. However, there is another phenomenon that looks very much like metaphysical naturalness but is context-dependent. I (...) call this phenomenon context-dependent naturalness. In this paper I describe two cases in which inappropriate use is made of metaphysical naturalness and argue that in such cases, the context-dependent importance of certain properties has been confused for the context-independent importance of those properties. I argue that in order to avoid such problems we should embrace context-dependent naturalness. (shrink)

“Realization” is a technical term that is used by metaphysicians, philosophers of mind, and philosophers of science to denote some dependence relation that is thought to obtain between higher-level properties and lower-level properties. It is said that mental properties are realized by physical properties; functional and computational properties are realized by first-order properties that occupy certain causal/functional roles; dispositional properties are realized by categorical properties; so on and so forth. Given this wide usage of the term “realization”, it would be (...) right to think that there might be different dependence relations that this term denotes in different cases. Any relation that is aptly picked out by this term can be taken to be a realization relation. The aim of this state-of-the-field article is to introduce the central questions about the concept of realization, and provide formulations of a number of realization relations. In doing so, I identify some theoretical roles realization relations should play, and discuss some theories of realization in relation to these theoretical roles. (shrink)

In constructing semantic theories of normative and evaluative terms, philosophers have commonly deployed a certain type of disagreement -based argument. The premise of the argument observes the possibility of genuine disagreement between users of a certain normative or evaluative term, while the conclusion of the argument is that, however differently those speakers employ the term, they must mean the same thing by it. After all, if they did not, then they would not really disagree. We argue that in many of (...) the cases in which this argument is deployed, the conclusion not only fails to follow from the premises, but is very likely false. Disagreements between speakers who do not mean the same things by their words are common, genuine, and not easily distinguished from ordinary disagreements over the truth of literally expressed content. We make this case by developing the notion of a metalinguistic negotiation, an exchange in which speakers tacitly negotiate the proper deployment of some linguistic expression in a context. Metalinguistic negotiations express disagreements over information that is conveyed pragmatically and about what concepts should be deployed in the context at hand. We argue that neither of these features poses any obstacle to metalinguistic negotiations serving to express genuine, substantive disagreements that can be well worth engaging in. Contrary to what has been widely assumed in the literature, many normative and evaluative disputes—among ordinary speakers and even among philosophers themselves—may be of exactly this type, a conclusion with important consequences for both the subject matter and the methodology of metanormative theory.

Normative realists might be assumed to have few worries about semantics. After all, a realist might initially hope to simply adopt the best semantic theory about ordinary descriptive language. However, beginning with the non-cognitivist appropriation of the open question argument, a number of philosophers have posed serious objections to the realist’s ability to offer a plausible semantic theory. This paper introduces the two most influential semantic challenges to normative realism: the open question argument, and the Moral Twin Earth argument. It (...) explains the major replies to these challenges offered by realists, and locates these challenges within the broader debate over what sort of semantic theories might be plausible candidates for a normative realist to adopt.

Hilary Putnam's Twin Earth thought experiment has come to have an enormous impact on contemporary philosophical thought. But while most of the discussion has taken place within the context of the philosophy of mind and language, Terence Horgan and Mark Timmons (H8cT) have defended the intriguing suggestion that a variation on the original thought experiment has important consequences for ethics.' In a series of papers, they' ve developed the idea of a Moral Twin Earth and have argued that its significance (...) is that it has the resources to undermine naturalistic versions of moral realism.'

In Finite and Infinite Goods, Adams develops a sophisticated and richly detailed Platonic-theistic framework for ethics. The view is Platonic in virtue of being Good-centered; it is theistic both in identifying God with the Good and, more distinctively, in including a divine command theory of moral obligation. Readers familiar with Adams’s earlier divine command theory will recall that in response to the worry that God might command something evil, Adams introduced an independent value constraint, claiming that only the commands of (...) a loving God were fit to constitute moral obligations. In Finite and Infinite Goods he develops this notion of a loving and good God in what is now a fundamentally Good-centered ethical framework with a subordinate divine command theory of moral obligation. There is much of worth here, especially for theists wishing to think through the merits of a good-based theistic ethics, but also for those nontheists like myself who have a general interest in the nature of value and obligation.

The prospects for moral realism and ethical naturalism have been important parts of recent debates within metaethics. As a first approximation, moral realism is the claim that there are facts or truths about moral matters that are objective in the sense that they obtain independently of the moral beliefs or attitudes of appraisers. Ethical naturalism is the claim that moral properties of people, actions, and institutions are natural, rather than occult or supernatural, features of the world. Though these metaethical debates (...) remain unsettled, several people, myself included, have tried to defend the plausibility of both moral realism and ethical naturalism. I, among others, have appealed to recent work in the philosophy of language—in particular, to so-called theories of “direct reference” —to defend ethical naturalism against a variety of semantic worries, including G. E. Moore's “open question argument.” In response to these arguments, critics have expressed doubts about the compatibility of moral realism and direct reference. In this essay, I explain these doubts, and then sketch the beginnings of an answer—but understanding both the doubts and my answer requires some intellectual background. (shrink)

Abstract: There has recently been controversy over the existence of 'multiple realization' in addition to some confusion between different conceptions of its nature. To resolve these problems, we focus on concrete examples from the sciences to provide precise accounts of the scientific concepts of 'realization' and 'multiple realization' that have played key roles in recent debates in the philosophy of science and philosophy of psychology. We illustrate the advantages of our view over a prominent rival account ( Shapiro, 2000 and (...) 2004 ) and use our work to rebut recent objections to the long-standing claim that psychological properties are multiply realized. For we use scientific evidence, in combination with our more precise theoretical framework, to show that we have strong reason to believe that psychological properties are indeed multiply realized both at the biochemical and neuronal levels.

David B. Wong proposes that there can be a plurality of true moralities, moralities that exist across different traditions and cultures, all of which address facets of the same problem: how we are to live well together. Wong examines a wide array of positions and texts within the Western canon as well as in Chinese philosophy, and draws on philosophy, psychology, evolutionary theory, history, and literature, to make a case for the importance of pluralism in moral life, and to establish (...) the virtues of acceptance and accommodation. Wong's point is that there is no single value or principle or ordering of values and principles that offers a uniquely true path for human living, but variations according to different contexts that carry within them a common core of human values. We should thus be modest about our own morality, learn from other approaches, and accommodate different practices in our pluralistic society. (shrink)

Moral claims not only purport to be true, they also purport to guide our choices. This book presents a new theory of normative judgment, the "standard-based theory," which offers a schematic account of the truth conditions of normative propositions of all kinds, including moral propositions and propositions about reasons. The heart of Copp 's approach to moral propositions is a theory of the circumstances under which corresponding moral standards qualify as justified, the " society -centered theory." He argues that because (...) any society needs a social moral code in order to enable its members to live together successfully, and because it would be rational for a society to choose such a code, certain moral codes, and the standards they include, are justified. According to the standard-based theory then, if certain moral standards are indeed justified, corresponding moral propositions may be true. Copp 's approach to morality and explaining normativity and the truth conditions of moral claims, raises a number of important issues in moral theory, as well as in metaphysics and the philosophy of language.

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.

In "Milk, Honey, and the Good Life on Moral Twin Earth", David Copp explores some ways in which a defender of synthetic moral naturalism might attempt to get around our Moral Twin Earth argument. Copp nicely brings out the force of our argument, not only through his exposition of it, but through his attempt to defeat it, since his efforts, we think, only help to make manifest the deep difficulties the Moral Twin Earth argument poses for the synthetic moral naturalist.

Contemporary realist theories of value claim to be compatible with natural science. In this paper, I call this claim into question by arguing that Darwinian considerations pose a dilemma for these theories. The main thrust of my argument is this. Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes. The challenge for realist theories of value is to explain the relation between these evolutionary influences on our evaluative attitudes, on the one hand, and the (...) independent evaluative truths that realism posits, on the other. Realism, I argue, can give no satisfactory account of this relation. On the one hand, the realist may claim that there is no relation between evolutionary influences on our evaluative attitudes and independent evaluative truths. But this claim leads to the implausible skeptical result that most of our evaluative judgements are off track due to the distorting pressure of Darwinian forces. The realist’s other option is to claim that there is a relation between evolutionary influences and independent evaluative truths, namely that natural selection favored ancestors who were able to grasp those truths. But this account, I argue, is unacceptable on scientific grounds. Either way, then, realist theories of value prove unable to accommodate the fact that Darwinian forces have deeply influenced the content of human values. After responding to three objections, the third of which leads me to argue against a realist understanding of the disvalue of pain, I conclude by sketching how antirealism is able to sidestep the dilemma I have presented. Antirealist theories of value are able to offer an alternative account of the relation between evolutionary forces and evaluative facts —
an account that allows us to reconcile our understanding of evaluative truth with our understanding of the many non-rational causes that have played a role in shaping our evaluative judgements. (shrink)

For nearly thirty years, there has been a consensus (at least in English-speaking countries) that reductionism is a mistake and that there are autonomous special sciences. This consensus has been based on an argument from multiple realizability. But Jaegwon Kim has argued persuasively that the multiple realizability argument is flawed.1 I will sketch the recent history of the debate, arguing that much --but not all--of the anti-reductionist consensus survives Kim's critique. This paper was originally titled "Anti-Reductionism Strikes Back", but in (...) the course of writing the paper, I came to think that the concepts used in the debate would not serve either position very well.

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

In this paper, I show how realist moral naturalists can provide an intra-theoretic explanation of the epistemic possibility of wholesale moral error. This is a requirement on metaethical theories that has been recently defended by Akhlaghi (2021). After clarifying Akhlaghi’s argument and responding to Evers’s (2021) recent rebuttal, I argue that even under the assumption that moral facts are grounded in an appropriate subset of natural facts (N-facts), there is still a non-zero probability of wholesale moral error. This is demonstrated (...) by considering three types of epistemically possible scenarios: specifically, it could either be that N-facts do not actually exist, or that N-facts exist in a way that entails wholesale moral error, or that N-facts exist in a non-error theoretic way, but their existence is temporally restricted.

Moral realists often disagree about the nature of moral properties. These properties can be natural (as per naturalistic moral realism) or non-natural. But it is unclear how we should understand the notion of naturalness employed in these discussions. In this paper I propose a novel account of moral naturalness. I suggest that a property F is natural iff F falls within the scope of a natural law. In turn, a law is natural when it figures in a nomic nexus involving (...) the laws of physics. (shrink)

It is commonly maintained that neuroplastic mechanisms in the brain provide empirical support for the hypothesis of multiple realizability. We show in various case studies that neuroplasticity stems from preexisting mechanisms and processes inherent in the neural structure of the brain. We argue that not only does neuroplasticity fail to provide empirical evidence of multiple realization, its inability to do so strengthens the mind-body identity theory. Finally, we argue that a recently proposed identity theory called Flat Physicalism can be enlisted (...) to explain the current state of the mind-body problem more adequately. (shrink)

Nearly 30 years ago, Terry Horgan and Mark Timmons published a now- popular article that combines Hilary Putnam’s Twin Earth scenario with G.E. Moore’s open question argument in an effort to show that moral naturalism – the view that moral facts are at bottom ordinary, natural facts of some sort – is probably false. Responses to Horgan and Timmons’s “revised open question argument” have been legion, but surprisingly, no one has attempted to test the core assumption upon which the argument (...) is based; namely, that competent language users univocally treat natural kind-terms as rigid designators. Here, I present evidence that the intuitions of competent English speakers are not as univocal as Horgan and Timmons need them to be to ground their argument against moral naturalism. I also briefly sketch a way that the moral naturalist can respond even if competent language speakers do treat natural-kind terms in the way that Horgan and Timmons suggest. (shrink)

The Moral Twin Earth challenge to ethical naturalism threatens to undermine an otherwise promising metaethical view by showing that typical, naturalist-friendly theories of reference determination predict diverging reference in Twin Earth scenarios, making it difficult to account for substantive moral disagreement. Several theorists have recently invoked David Lewis’s doctrine of reference magnetism as a solution, claiming that a highly elite moral property—a moral “joint in nature”—could secure shared reference between ourselves and our twins on Twin Earth, despite our diverging usages (...) of moral terms. This paper argues that this move has significant methodological implications: namely, it entails that a certain sort of simplicity is truth-conducive. Consequently, when applied to moral theories, this gives certain views, specifically monist ones like utilitarianism and contractualism, an advantage over their more complicated rivals, forms of pluralism and particularism. Thus, ethical naturalists cannot invoke reference magnetism without a substantial impact on first-order theorizing. (shrink)

What considerations place genuine constraints on an adequate semantics for normative and evaluative expressions? Linguists recognize facts about ordinary uses of such expressions and competent speakers’ judgments about which uses are appropriate. The contemporary literature reflects the widespread assumption that linguists don’t rely upon an additional source of data—competent speakers’ judgments about possible disagreement with hypothetical speech communities. We have several good reasons to think that such judgments are not probative for semantic theorizing. Therefore, we should accord these judgments no (...) probative value for the development of a semantics for our moral terms. Such judgments can no longer be presumed to put pressure on theories according to which our moral expressions share a semantics with ordinary, descriptive terms. Many rivals to pure, Descriptivist theories count among their advantages the ability to accommodate these judgments. If these judgments have no probative value, such theories lose an important source of support. (shrink)

When we disagree with each other at the beginning of a debate, we are confident that we are right and the other side is just wrong, 2017). But at the end of the debate, we could be persuaded that we are wrong and the other side is right. This happens a lot when we disagree on empirical or factual claims. However, when we disagree with each other on moral issues, it is quite rare that either side is persuaded. We could (...) be frustrated by the other’s stubbornness. But sometimes we come to see that the other side has a point. Their view seems reasonable. We might even feel that we could have taken their moral perspective and values. This phenomenon of moral ambivalence is discussed extensively by David Wong as part of his argument for moral relativism that there is no single true morality. Recently, Agustín Vicente and Agustín Arrieta write to refute Wong’s argument. They argue that moral ambivalence is a phenomenon of moral pluralism, the position that there are different acceptable courses of actions, rather than moral relativism. In this paper, I argue that moral ambivalence does not support the kind of moral pluralism that Vicente and Arrieta argue for. Furthermore, I point out that moral ambivalence does not support Wong’s naturalism, the position that morality has human nature constraints, but it does support the kind of relativism that he endorses.

This paper offers a simple response to the Moral Twin Earth (MTE) objection to Naturalist Moral Realism (NMR). NMR typically relies on an externalist metasemantics such as a causal theory of reference. The MTE objection is that such a theory predicts that terms like ‘good’ and ‘right’ have a different reference in certain twin communities where it’s intuitively clear that the twins are talking about the same thing when using ‘good’. I argue that Boyd’s causal regulation theory, the original target (...) of the MTE objection, was never vulnerable to this objection. The theory contains an epistemic constraint on reference which implies that either the property that causally regulates uses of ‘good’ isn’t different for the twin communities or, in scenarios where the reference is different, the communities diverge in ways where it’s not intuitively clear that ‘good’ has the same reference for them.

3.0. Well-being as a Challenge to Naturalism. In Chapter Three Adams discusses and criticizes those accounts of a person’s well being which characterize it in terms of counterfactuals regarding her actual desires and preferences. These criticisms are important for the question of ethical naturalism because any plausible naturalist position will have to portray a person’s well-being as somehow or other supervening on features of her psychology and her environment. The sorts of analyses Adams criticizes are the most prominent analyses consistent (...) with this constraint, so it is important to see whether or not Adams’ criticisms of them undermine the prospects for ethical naturalism generally.

0.0. Theistic Ethics as a Challenge and a Diagnostic Tool. Naturalistic conceptions in metaethics come in many varieties. Many philosophers who have sought to situate moral reasoning in a naturalistic metaphysical conception have thought it necessary to adopt non-cognitivist, prescriptivist, projectivist, relativist, or otherwise deflationary conceptions. Recently there has been a revival of interest in non-deflationary moral realist approaches to ethical naturalism. Many non-deflationary approaches have exploited the resources of non-empiricist “causal” or “naturalistic” conceptions of reference and of kind definitions (...) in service of the “naturalistic” metaphilosophical conception that substantive moral questions, and questions about the metaphysics of morals, are broadly a posteriori questions, somewhat analogous to scientific questions, and are not amenable to a priori resolution by “conceptual analysis.”.

A number of philosophers defend naturalistic moral realism by appeal to an externalist semantics for moral predicates. The application of semantic externalism to moral predicates has been attacked by Terence Horgan and Mark Timmons in a series of papers that make use of their “ Moral Twin Earth ” thought experiment. In response, several defenders of naturalistic moral realism have claimed that the Moral Twin Earth thought experiment is misleading and yields distorted and inaccurate semantic intuitions. If they are right, (...) the intuitions generated by Moral Twin Earth cannot be appealed to in arguments against externalist moral semantics. The most developed case against the Moral Twin Earth argument that follows this strategy is found in a paper by Stephen Laurence, Eric Margolis and Angus Dawson. Here I argue that their attack on the Moral Twin Earth thought experiment fails. Laurence, Margolis and Dawson have not shown that we have reason to distrust the semantic intuitions it generates.

In Physical Realization, Sydney Shoemaker considers the question of how physicalism can be true: how can all facts about the world, including mental ones, be constituted by facts about the distribution in the world of physical properties? Physicalism requires that the mental properties of a person are 'realized in' the physical properties of that person, and that all instantiations of properties in macroscopic objects are realized in microphysical states of affairs. Shoemaker offers an account of both these sorts of realization, (...) one which allows the realized properties to be causally efficacious. He also explores the implications of this account for a wide range of metaphysical issues, including the nature of persistence through time, the problem of material constitution, the possibility of emergent properties, and the nature of phenomenal consciousness.
