This introduction provides a highly readable critical overview of the main arguments and themes in twentieth-century and contemporary metaethics. It traces the development of contemporary debates in metaethics from their beginnings in the work of G. E. Moore up to the most recent arguments between naturalism and non-naturalism, cognitivism and non-cognitivism. A highly readable critical overview of the main arguments and themes in twentieth century and contemporary metaethics. Asks: Are there moral facts? Is there such a thing as moral truth? (...) Is moral knowledge possible? Traces the development of contemporary debates in metaethics from their beginnings in the work of G. E. Moore up to the most recent debates between naturalism and non-naturalism, cognitivism and noncognitivism. Provides for the first time a critical survey of famous figures in twentieth century metaethics such as Moore, Ayer and Mackie together with in-depth discussions of contemporary philosophers such as Blackburn, Gibbard, Wright, Harman, Railton, Sturgeon, McDowell and Wiggins.

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.

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. (shrink)

In order to rebut G. E. Moore’s open question argument, ethical naturalists adopt a theory of direct reference for our moral terms. T. Horgan and M. Timmons have argued that this theory cannot be applied to moral terms, on the ground that it clashes with competent speakers’ linguistic intuitions. While Putnam’s Twin Earth thought experiment shows that our linguistic intuitions confirm the theory of direct reference, as applied to ‘water’, Horgan and Timmons devise a parallel thought experiment about moral terms, (...) in order to show that this theory runs against our linguistic intuitions about such terms. My claim is that the Horgan–Timmons argument does not work. I concede that their thought experiment is a good way to test the applicability of the theory of direct reference to moral terms, and argue that the upshot of their experiment is not what they claim it is: our linguistic intuitions about Moral Twin Earth are parallel to, not different from, our intuitions about Twin Earth.

Terence Horgan and Mark Timmons's ' moral twin earth argument' raises doubts about the naturalistic realist's ability to make sense of genuine disagreement. I offer three arguments the realist's behalf. First, I argue that the example at the heart of their argument is underdescribed; when fully developed, it loses its intuitive force. Second, I suggest that taking the stipulations of the Horgan-Timmons example seriously gives us reason to revise our initial judgments. Third, I propose combining naturalistic realism about moral judgments (...) with expressivism about the last ought before action in order to preserve the conflict between moralists and twin -moralists.

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.

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.' H8t T don't hold back in their assessment. "Moral Twin.. (shrink)

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.
