In recent years, defenses of moral realism have embraced what we call new wave moral semantics', which construes the semantic workings of moral terms like good' and right' as akin to the semantic workings of natural-kind terms in science and also takes inspiration from functionalist themes in the philosophy of mind. This sort of semantic view which we find in the metaethical views of David Brink, Richard Boyd, Peter Railton, is the crucial semantical underpinning of a naturalistic brand of moral realism that these philosophers favor--a view that promises to deliver a robust form of moral realism. We argue that new wave moral semantics leads, in one way or another, to moral relativism--a view that is incompatible with the kind of moral realism these philosophers aim to defend.

Is conceptual relativity a genuine phenomenon? If so, how is it properly understood? And if it does occur, does it undermine metaphysical realism? These are the questions we propose to address. We will argue that conceptual relativity is indeed a genuine phenomenon, albeit an extremely puzzling one. We will offer an account of it. And we will argue that it is entirely compatible with metaphysical realism. Metaphysical realism is the view that there is a world of objects and properties that is independent of our thought and discourse (including our schemes of concepts) about such a world. Hilary Putnam, a former proponent of metaphysical realism, later gave it up largely because of the alleged phenomenon that he himself has given the label ‘conceptual relativity’. One of the key ideas of conceptual relativity is that certain concepts—including such fundamental concepts as object, entity, and existence—have a multiplicity of different and incompatible uses (Putnam 1987, p. 19; 1988, pp. 110 14). According to Putnam, once we recognize the phenomenon of conceptual relativity we must reject metaphysical realism: The suggestion . . . is that what is (by commonsense standards) the same situation can be described in many different ways, depending on how we use the words. The situation does not itself legislate how words like “object,” “entity,” and “exist” must be used. What is wrong with the notion of objects existing “independently” of conceptual schemes is that there are no standards for the use of even the logical notions apart from conceptual choices.” (Putnam 1988, p. 114) Putnam’s intriguing reasoning in this passage is difficult to evaluate directly, because conceptual [1] relativity is philosophically perplexing and in general is not well understood. In this paper we propose a construal of conceptual relativity that clarifies it considerably and explains how it is possible despite its initial air of paradox. We then draw upon this construal to explain why, contrary to Putnam and others, conceptual relativity does not conflict with metaphysical realism, but in fact comports well with it..

In this book Timmons defends a metaethical view that exploits certain contextualist themes in philosophy of language and epistemology. He advances what he calls assertoric non-descriptivism, a view that employs semantic contextualism in giving an account of moral discourse. This view, which like traditional non-descriptivist views stresses the practical, action-guiding function of moral thought and discourse, also allows that moral sentences, as typically used, make genuine assertions. Timmons then defends a contextualist moral epistemology thus completing his overall program of contextualism in ethics.

There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to (most) moral questions, and the possibility of knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

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 (most of them specially written for the volume) represent the most up-to-date work in metaethics after, and in some cases directly inspired by, the work of Moore.
