This book is a systematic and constructive treatment of a number of traditional issues at the foundations of ethics. These issues concern the objectivity of ethics, the possibility and nature of moral knowledge, the relationship between the moral point of view and a scientific or naturalist world-view, the nature of moral value and obligation, and the role of morality in a person's rational lifeplan. In striking contrast to traditional and more recent work in the field, David Brink offers an integrated (...) defense of the objectivity of ethics. (shrink)

1. Evolutionary Moral Realism. On most contemporary approaches to evolution and ethics, morality is not a real part of the environment in which social and intelligent creatures evolve.1 According to such approaches, certain cooperative behavioural patterns develop, and thus become biologically real, but morality doesn’t become possible until creatures evolve a sophisticated enough cognitive ability to mistake the goals of such behavioural patterns for objective moral values. At a metaethical level, this line of thought has led evolutionary biologists and moral (...) philosophers alike to the conclusion that objective moral values are illusory. At an ethical level, the same line of thought has led most moral philosophers to suppose that evolutionary biology tells us nothing very important about ethics. Ethics is possible because of our evolutionary heritage as cooperative primates, but ethics itself only begins as we humans begin to talk, argue and reason about how we ought to live our lives together. With the standard view, we think morality is tied to cooperative behavioural patterns that.. (shrink)

Moral Projectivism must be able to specify under what conditions a certain inner response counts as a moral response. I argue, however, that moral projectivists cannot coherently do so because they must assume that there are moral properties in the world in order to fix the content of our moral judgements. To show this, I develop a number of arguments against moral dispositionalism, which is, nowadays, the most promising version of moral projectivism. In this context, I call into question both (...) David Lewis’ dispositionalist account of colour and Chistine Korsgaard’s procedural realism. (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 essay explains for a general philosophical audience the central issues and strategies in the contemporary moral realism debate. It critically surveys the contribution of some recent scholarship, representing expressivist and pragmatist nondescriptivism (Mark Timmons, Hilary Putnam), subjectivist and nonsubjectivist naturalism (Michael Smith, Paul Bloomfield, Philippa Foot), nonnaturalism (Russ Shafer-Landau, T. M. Scanlon) and error theory (Richard Joyce). Four different faces of ‘moral realism’ are distinguished: semantic, ontological, metaphysical, and normative. The debate is presented as taking shape under dialectical pressure (...) from the demands of (i) capturing the moral appearances and (ii) reconciling morality with our understanding of the mind and world.

A prominent argument for moral realism notes that we are inclined to accept realism in science because scientific inquiry supports a robust set of critical practices—error, improvement, explanation, and the like. It then argues that because morality displays a comparable set of critical practices, a claim to moral realism is just as warranted as a claim to scientific realism. But the argument is only as strong as its central analogy—and here there is trouble. If the analogy between the critical practices (...) of science and morality is loosely interpreted, the argument does not support moral realism—for paradigmatically constructivist discourses like fashion display the relevant critical practices just as well. So if the argument is to have force, the realist must say more about why the critical practices of morality are sufficiently like those of science to warrant realism. But this cannot be done—moral inquiry differs from scientific inquiry in too many important ways. So the analogy with the critical practices of science fails to vindicate moral realism. But there are further lessons: in looking closely at the critical practices of our moral discourse—and in comparing them to the critical practices of science and fashion—we gain insight into what is distinctive about morality objectivity and moral metaphysics.

Some moral realists claim that moral facts are a species of natural fact, amenable to scientific investigation. They argue that these moral facts are needed in the best explanations of certain phenomena and that this is evidence that they are real. In this paper I present part of a biological account of the function of morality. The account allows the identification of a plausible natural kind that could play the explanatory role that a moral kind would play in naturalist realist (...) theories. It is therefore a candidate for being the moral kind. I argue, however, that it will underdetermine the morally good, that is, identifying the kind is not sufficient to identify what is good. Hence this is not a natural moral kind. Its explanatory usefulness, however, means that we do not have to postulate any further (moral) facts to provide moral explanations. Hence there is no reason to believe that there are any natural moral kinds. (shrink)

Alexander Miller has recently considered an ingenious extension of Frank Jackson and Philip Pettit's account of 'program explanation' as a way of defending non-reductive naturalist versions of moral realism against Harman's explanatory criticism. Despite the ingenuity of this extension, Miller concludes that program explanation cannot help such moral realists in their attempt to defend moral properties. Specifically, he argues that such moral program explanations are dispensable from an epistemically unlimited point of view. I show that Miller's argument for this negative (...) claim is inadequate, and that he has, in spite of himself, identified a promising defence of moral realism. (shrink)

This paper argues for the view that moral realism is irrelevant to ethics. It recalls Aristotle's claim that the Platonic Form of the Good is irrelevant because it is not the sort of thing we can desire or pursue. Moore's account of ethics in relation to conduct and of the Ideal is woefully inadequate as a morality to live by. Peter Railton's moral realism also involves a very weak first-order moral theory. These failures are due, I claim, to the fact (...) that Plato, Moore and Railton regard morality as a science; it is not a science, it is an art. (shrink)

I argue that ethical reductionism is better than nonreductionism at fitting moral properties into successful scientific explanations and doesn't face the kind of multiple realizability that threatens reductionism in philosophy of mind.

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different moral properties are supposed (...) to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

Moral metaphysics is that part of philosophy concerned with establishing the exact ontological status of ethical facts. There are many possible views concerning the ontological status of such facts – including, of course, the view that there are none. The purpose of the present essay is to present a short survey of the most important of the positive views about ethical facts, unapologetically written from the perspective of contemporary metaethics. Since the early twentieth century, moral philosophy has seen previously unparalleled (...) efforts to clearly separate out and delineate distinct moral metaphysical theories, and such carefully delineated theories, apart from each being interesting in their own right, also provide us with conceptual tools which we can use when studying the longer history of ethics. This is not at all to devalue efforts that might instead be made to study particular figures or earlier episodes in that history more on their own terms, nor to deny that the present approach risks falling into the trap of anachronism. Suffice to say, an essay that covered the long history of moral metaphysics on every period’s own terms would either be incredibly long, or need be even more patchy than the present essay is. (shrink)
