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 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.

In this paper I trace the development of one of the central debates of late twentieth-century moral philosophy—the debate between realism and what Rawls called “constructivism.” Realism, I argue, is a reactive position that arises in response to almost every attempt to give a substantive explanation of morality. It results from the realist’s belief that such explanations inevitably reduce moral phenomena to natural phenomena. I trace this belief, and the essence of realism, to a view about the nature of concepts—that (...) it is the function of all concepts to describe reality. Constructivism may be understood as the alternative view that a normative concept refers schematically to the solution to a practical problem. A constructivist account of a concept, unlike a traditional analysis, is an attemptto work out the solution to that problem. I explain how the philosophies of Kant and Rawls can be understood on this model. (shrink)

Ethical concepts are, or purport to be, normative. They make claims on us: they command, oblige, recommend, or guide. Or at least when we invoke them, we make claims on one another; but where does their authority over us - or ours over one another - come from? Christine Korsgaard identifies four accounts of the source of normativity that have been advocated by modern moral philosophers: voluntarism, realism, reflective endorsement, and the appeal to autonomy. She traces their history, showing how (...) each developed in response to the prior one and comparing their early versions with those on the contemporary philosophical scene. Kant's theory that normativity springs from our own autonomy emerges as a synthesis of the other three, and Korsgaard concludes with her own version of the Kantian account. Her discussion is followed by commentary from G. A. Cohen, Raymond Geuss, Thomas Nagel, and Bernard Williams, and a reply by Korsgaard. (shrink)

A common first reaction to expressivist and quasi-realist theories is the thought that, if these theories are right, there's some objectionable sense in which we can't be wrong about morality. This worry turns out to be surprisingly difficult to make stick - an account of moral error as instability under improving changes provides the quasi-realist with the resources to explain many of our concerns about moral error. The story breaks down, though, in the case of fundamental moral error. This is (...) where the initial worry finally sticks - quasi-realism tells me that I can't be fundamentally wrong about morality, though others can. (shrink)

Critical notice of 'From metaphysics to ethics' by Frank Jackson.

Different forms of ethical naturalism are distinguished, and the possibility of a blockbuster argument against all of them at once is raised. Moore’s Open Question Argument proves insufficient; more recent anti-naturalist arguments by Derek Parfit are outlined. It is necessary to get a clearer view of what normativity is before one can decide whether naturalism abolishes normativity, as Parfit claims. An initial account of normativity is therefore given, and the prospects of a blockbuster argument are reconsidered.

Moral phenomenology is concerned with the elements of one's moral experiences that are generally available to introspection. Some philosophers argue that one's moral experiences, such as experiencing oneself as being morally obligated to perform some action on some occasion, contain elements that (1) are available to introspection and (2) carry ontological objectivist purportargument from phenomenological introspection.neutrality thesisthe phenomenological data regarding one's moral experiences that is available to introspection is neutral with respect to the issue of whether such experiences carry ontological (...) objectivist purport.

I begin by distinguishing two general approaches to metaethics and ontology. One in effect puts our experience as engaged ethical agents on hold while independent metaphysical and epistemological inquiries, operating by their own lights, deliver metaethical verdicts on acceptable interpretations of our ethical lives; the other instead keeps engaged ethical experience in focus and allows our reflective interpretation of it to shape our metaphysical and epistemological views, including our ontology. While the former approach often leads to deflationary views, the latter (...) may lead us to enrich our metaethical picture as needed to capture robust objectivity and categorical normative authority for ethics. Assuming, as I have argued elsewhere, that this requires positing irreducibly evaluative or normative properties and facts, the question I take up here is what ontological implications this has. I argue against quietist non-naturalist views, which maintain that positing such properties and facts either has no ontological implications or has only domain-specific ontological implications that likewise imply nothing about what the world contains. Against these views, I advocate a worldly, dual-aspect view, locating irreducibly evaluative or normative properties as features of relevant worldly things. But while I have previously defended this view as a form of non-naturalism, I here explore the possibility of instead seeing it as a new, more expansive form of naturalism—what might be called “Non-Scientistic Naturalism”—inspired by parallel attempts in the philosophy of mind to accommodate irreducibly phenomenal properties within a more expansive physicalism.
