Ronald Dworkin’s unity of value thesis underlies his influential moral, political, and legal thought. This essay presents an interpretation of the unity thesis designed to isolate its distinctly ethical character, elaborate Dworkin’s fundamental ethical arguments for it, and to utilize this reconstruction to correct misinterpretations that, I argue, underlie recent criticism. This criticism largely depends on construing the unity thesis within a familiar dualistic meta-ethical framework according to which Dworkin’s theory of value is classified as either constructivist or realist in (...) character. Both options, however, misapprehend the epistemological framework within which Dworkin defends value judgments in general, and therefore fail to challenge his use of that framework in defending the unity of value in particular. Correcting this oversight is essential to a proper understanding of Dworkin’s novel account of moral epistemology and of the moral and political program that his unity thesis sponsors. The paper concludes by suggesting how more profitable criticism of the unity of value might proceed. (shrink)

This paper seeks to clarify and defend the proposition that moral realism is best elaborated as a moral doctrine. I begin by upholding Ronald Dworkin’s anti-Archimedean critique of the error theory against some strictures by Michael Smith, and I then briefly suggest how a proponent of moral realism as a moral doctrine would respond to Smith’s defense of the Archimedeanism of expressivism. Thereafter, this paper moves to its chief endeavor. By differentiating clearly between expressivism and quasi-realism, the paper highlights both (...) their distinctness and their compatibility. In so doing, it underscores the affinities between Blackburnian quasi-realism and moral realism as a moral doctrine. Finally, this paper contends—in line with my earlier work on these matters—that moral realism as a moral doctrine points to the need for some reorienting of meta-ethical enquiries rather than for the abandoning of them.

Metaethics is traditionally understood as a non-moral discipline that examines moral judgements from a standpoint outside of ethics. This orthodox understanding has recently come under pressure from anti-Archimedeans, such as Ronald Dworkin and Matthew Kramer, who proclaim that rather than assessing morality from an external perspective, metaethical theses are themselves substantive moral claims. In this paper, I scrutinise this anti-Archimedean challenge as applied to the metaethical position of expressivism. More precisely, I examine the claim that expressivists do not avoid moral (...) commitments when accounting for moral thought, but instead presuppose them; they do not look at ethics from the outside, but operate from within ethics. This paper defends the non-moral status of expressivism against anti-Archimedeanism by rejecting a new anti-Archimedean challenge which, on the basis of Hume’s Law, aims to exploit expressivist explanations of supervenience in order to show that expressivism is a substantive moral position.
