A philosophical tradition is in part identified by its more durable controversies. The British tradition in moral philosophy running, roughly, from Hobbes to the present day, involves several fine examples of the type—the plausibility or otherwise of the compatibilist view of free will, the case for and against utilitarianism, and perhaps above all the implications of the fact/value distinction. It is always pleasing to find some new variation on such themes; you have a comforting sense of the inherent permanence of (...) this corner of the intellectual universe. Thus R. G. Swinburne's paper ‘The Objectivity of Morality’ is much to be welcomed as a contribution to a well-matured debate. Even more, perhaps, it is welcome on account of its considerable clarity. But clarity often comes at a high price, and the price in this case is too high. By setting out his version of the objectivist position with such precision and lack of ambiguity Professor Swinburne has made its difficulties and weaknesses accessible to all but the meanest intellect.

Moore's Open Question Arguments are among the most influential arguments in 20th Century metaethical thought. But, surprisingly, there is a fair amount of confusion concerning what the Open Question Arguments actually are, how the Moorean passages should be interpreted, and what they are intended to show. Thus, the early chapters are devoted to clarificatory matters, including the exposing of a variety of contemporary attacks upon Moore's arguments as misguided by indicating where they rest upon faulty interpretations of Moorean passages. Providing (...) what I take to be accurate formulations of Moore's famous arguments, responding to historically important preliminary objections, and, finally, presenting various shortcomings of these arguments constitute the remaining themes of the early chapters. ;Next, I pursue an explanation of what I call the 'Open Question phenomenon': the inclination that many have to endorse Moore's "open question" premises. I survey a variety of popular noncognitivist explanations, arguing that each of them is unsatisfactory. I then present a novel semantic explanation of the phenomenon and use it to construct an augmented Moorean Open Question Argument, one capable of overcoming the shortcomings of Moore's originals. ;The latter chapters are dedicated to an investigation of Moore's preferred normative theory---a version of objective consequentialism. I argue that the standard semantic account of subjunctive conditionals fails to capture the nature of certain subjunctive conditionals relevant to the normative evaluation of alternatives from an objective consequentialist perspective. I then present a modified version of the standard account in an effort to remedy the problem. ;Next, I present a novel objection against all extant versions of objective consequentialism. I then introduce and utilize the concept of an "objective" subjunctive probability in the transformation of a subjective version of consequentialism into an objective version, one capable of dealing with the difficulties posed by the objection. ;I conclude the dissertation with a final chapter in which I defend possibilist versions of consequentialism from a contemporary objection. In doing so, I elucidate a theoretical advantage that possibilist theories have over their subjunctive counterparts. (shrink)
