According to many, that the normative supervenes on the non-normative is a truism of normative discourse. This chapter argues that those committed to more specific moral, aesthetic, and epistemic supervenience theses should also hold (NS*): As a matter of conceptual necessity, whenever something has a normative property, it has a base property or collection of base properties that metaphysically necessitates the normative one. My main aim is to show that none of the available arguments establish (NS*), or indeed the relevant (...) epistemic, aesthetic, and moral supervenience theses. (NS*) is not a conceptual truth. This has considerable dialectical importance. One interesting upshot is that it affords non-reductivists and non-naturalists a novel way of resisting certain prominent supervenience-based objections to their views, including objections that formulate supervenience as a purely metaphysical thesis.

David Enoch develops, argues for, and defends a strongly realist and objectivist view of ethics and normativity more broadly. This view--according to which there are perfectly objective, universal, moral and other normative truths that are not in any way reducible to other, natural truths--is familiar, but this book is the first in-detail development of the positive motivations for the view into reasonably precise arguments. And when the book turns to defend Robust Realism against traditional objections, it mobilizes the original positive (...) arguments for the view to help with fending off the objections. (shrink)

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

It is often claimed that irreducibly normative truths would have unacceptable metaphysical implications, and are incompatible with a scientific view of the world. The book argues, on the basis of a general account of the relevance of ontological questions, that this claim is mistaken. It is also a mistake to think that interpreting normative judgments as beliefs would make it impossible to explain their connection with action. An agent’s acceptance of a normative judgment can explain that agent’s subsequent action because (...) it is part of being a rational agent that such an agent’s beliefs about reasons normally, but not invariably, make a difference to the agent’s subsequent behavior. Because facts about reasons are not entities existing apart from us, there is no epistemological problem of how we can “be in touch with” such facts. There are serious worries about normative knowledge, but the problems involved are internal to the normative domain itself. The best solution to these problems would be an overall account of the domain of reasons in normative terms, supported by an argument from reflective equilibrium. But no existing account, constructivist, or based on desires or on an idea of rationality, is plausible, and no alternative is likely to succeed. Conclusions about reasons for action must rest on more piecemeal applications of the method of reflective equilibrium. (shrink)

It is widely accepted that the ethical supervenes on the natural, where this is roughly the claim that it is impossible for two circumstances to be identical in all natural respects, but different in their ethical respects. This chapter refines and defends the traditional thought that this fact poses a significant challenge to ethical non-naturalism, a view on which ethical properties are fundamentally different in kind from natural properties. The challenge can be encapsulated in three core claims which the chapter (...) defends: that a defensible non-naturalism is committed to the supervenience of the ethical, that this commits the non-naturalist to a brute necessary connection between properties of distinct kinds, and that commitment to such brute connections counts against the non-naturalist’s view. Each of these claims has recently been challenged. Against Nicholas Sturgeon’s recent doubts about the dialectical force of supervenience, this chapter defends a supervenience thesis as deserving to be common ground among ethical realists. It is then argued that attempts to explain supervenience on behalf of the non-naturalist either fail as explanations, generate near-identical explanatory burdens elsewhere, or appeal to commitments that are inconsistent with core motivations for non-naturalism. The chapter concludes that, suitably refined, the traditional argument against nonnaturalism from supervenience is alive and well. (shrink)

In ethics, aesthetics and increasingly in epistemology, a distinction is drawn between thick and thin evaluative concepts. A common characterisation of the distinction is that thin concepts have only evaluative content, whereas thick concepts combine evaluative and descriptive content. Because of this combination, it is again commonly thought that thick concepts have various distinctive powers including the power to undermine the distinction between fact and value. This paper discusses the accuracy of this view of the thick concepts debate, as well (...) as assessing the prospects for a thick concepts argument against the fact value distinction, while introducing the three main philosophical positions on the nature of thick concepts.

This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

Many philosophers of the last century thought all moral judgments can be expressed using a few basic concepts — what are today called ‘thin’ moral concepts such as ‘good,’ ‘bad,’ ‘right,’ and ‘wrong.’ This was the view, fi rst, of the non-naturalists whose work dominated the early part of the century, including Henry Sidgwick, G.E. Moore, W.D. Ross, and C.D. Broad. Some of them recognized only one basic concept, usually either ‘ought’ or ‘good’; others thought there were two. But they (...) all assumed that other moral concepts, including such ‘thick’ ones as the virtue-concepts ‘courageous’ and ‘kindly,’ can be reductively analyzed using one or more thin concepts and some more or less determinate..

Long claimed to be the dominant conception of practical reason, the Humean theory that reasons for action are instrumental, or explained by desires, is the basis for a range of worries about the objective prescriptivity of morality. As a result, it has come under intense attack in recent decades. A wide variety of arguments have been advanced which purport to show that it is false, or surprisingly, even that it is incoherent. Slaves of the Passions aims to set the record (...) straight, by advancing a version of the Humean theory of reasons which withstands this sophisticated array of objections. Schroeder defends a radical new view which, if correct, means that the commitments of the Humean theory have been widely misunderstood. Along the way, he raises and addresses questions about the fundamental structure of reasons, the nature of normative explanations, the aims of and challenges facing reductive views in metaethics, the weight of reasons, the nature of desire, moral epistemology, and most importantly, the relationship between agent-relational and agent-neutral reasons for action.

Moral Realism is a systematic defence of the idea that there are objective moral standards. Russ Shafer-Landau argues that there are moral principles that are true independently of what anyone, anywhere, happens to think of them. His central thesis, as well as the many novel supporting arguments used to defend it, will spark much controversy among those concerned with the foundations of ethics.

It is my aim in this paper to show that the contemporary assimilation of essence to modality is fundamentally misguided and that, as a consequence, the corresponding conception of metaphysics should be given up. It is not my view that the modal account fails to capture anything which might reasonably be called a concept of essence. My point, rather, is that the notion of essence which is of central importance to the metaphysics of identity is not to be understood in (...) modal terms or even to be regarded as extensionally equivalent to a modal notion. The one notion is, if I am right, a highly refined version of the other; it is like a sieve which performs a similar function but with a much finer mesh. (shrink)

In addition to thin concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to thick concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind -- concepts that somehow combine evaluation and non-evaluative description. Thick concepts are almost universally assumed to be inherently evaluative in content, and many philosophers claimed them to have deep and distinctive significance in ethics and metaethics. In this first book-length treatment of thick (...) concepts, Pekka Väyrynen argues that all this is mistaken. Through detailed attention to the language of thick concepts, he defends a novel theory on which the relationship between thick words and evaluation is best explained by general conversational and pragmatic norms. Drawing on general principles in philosophy of language, he argues that many prominent features of thick words and concepts can be explained by general factors that have nothing in particular to do with being evaluative. If evaluation is not essential to the sort of thinking we do with thick concepts, claims for the deep and distinctive significance of the thick are undermined. The Lewd, the Rude and the Nasty is a fresh and innovative treatment of an important topic in moral philosophy and sets a new agenda for future work. It will be essential reading to anyone interested in the analysis and the broader philosophical significance of evaluative and normative language. (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)

This chapter discusses whether Quasi-Realism gains any advantage over Robust Realism with respect to the problem of explaining supervenience. The chapter starts with a summary of what the supervenience problem is and recounts the history of expressivist thinking about supervenience: the supervenience problem was a challenge raised by expressivist Robust Realists, with the idea that expressivism had an excellent explanation of the phenomenon and realism had none. The chapter then contrasts Quasi-Realism and Robust Realism in order to bring the big (...) problem out in the open, namely that Quasi-Realists have not provided any explanation at all for the phenomenon of supervenience. In this respect they are, it appears, in the same boat as Robust Realists. The chapter maps out the possible paths for Quasi-Realists to travel in pursuit of Quasi-Explananda, and gives some reasons to be optimistic. The chapter ends with a suggestive analogy and a synopsis of the state of the dialectic. (shrink)

Like much in this book, the title and dust jacket illustration are clever. The first evokes Hume's remark in the Treatise that ‘Reason is, and ought only to be the slave of the passions.’ The second, which represents a cross between a dance-step and a clinch, links up with the title and anticipates an example used throughout the book to support its central claims: that Ronnie, unlike Bradley, has a reason to go to a party – namely, that there will (...) be dancing at the party – because Ronnie, unlike Bradley, loves dancing. So, the explanation of why Ronnie's and Bradley's reasons differ lies in their respective psychologies.Schroeder argues for a version of the Humean Theory of Reasons he calls Hypotheticalism, which says that every reason is explained by a desire in the same way as Ronnie's is. Schroeder argues that on almost every count, Hypotheticalism is as good as, or preferable to, the Humean and non-Humean alternatives; and he defends it against an array of objections. For example, he explains that while Hypotheticalism claims that ‘desires have to serve in the explanation of every reason because desires are part of the correct analysis of reasons’, it does not claim that a desire that explains a reason is part of that reason: rather it is a background condition for it. This, Schroeder argues, allows him to rebut a variety of objections that depend on conflating reasons with their background conditions. Other …. (shrink)

In this paper, I argue that anti-reductionist moral realism still has trouble explaining supervenience. My main target here will be Russ Shafer-Landau's attempt to explain the supervenience of the moral on the natural in terms of the constitution of moral property instantiations by natural property instantiations. First, though, I discuss a recent challenge to the very idea of using supervenience as a dialectical weapon posed by Nicholas Sturgeon. With a suitably formulated supervenience thesis in hand, I try to show how (...) Shafer-Landau's proffered strategy to explain supervenience not only fails to explain supervenience, but that it also has a number of implausible consequences. The more general lesson is that strategies which may work well for explaining supervenience in the philosophy of mind and other areas cannot be assumed to carry over successfully to the metaethical context. We should therefore treat so-called `companions in guilt' arguments in this area of philosophy with considerable skepticism. Key Words: expressivism • moral realism • non-naturalism • reductionism • supervenience • trope. (shrink)

This chapter argues that the best way for a non-naturalist to explain why the normative supervenes on the natural is to claim that, while there are some sui generis normative properties whose essences cannot be fully specified in non-normative terms and do not specify any non-normative sufficient conditions for their instantiation, there are certain hybrid normative properties whose essences specify both naturalistic sufficient conditions for their own instantiation and sufficient conditions for the instantiation of certain sui generis normative properties. This (...) is the only metaphysical explanation for supervenience on offer, the chapter argues, that can both clearly maintain the pre-theoretical commitments of non-naturalism, and provide a metaphysical explanation not just for supervenience, but for all metaphysical necessities involving natural and normative properties.

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)

Michael Ridge presents an original expressivist theory of normative judgments--Ecumenical Expressivism--which offers distinctive treatments of key problems in metaethics, semantics, and practical reasoning. He argues that normative judgments are hybrid states partly constituted by ordinary beliefs and partly constituted by desire-like states.
