Ethical descriptivism is the view that all ethical properties are descriptive properties. Frank Jackson has proposed an argument for this view which begins with the premise that the ethical supervenes on the descriptive, any worlds that differ ethically must differ also descriptively. This paper observes that Jackson's argument has a curious structure, taking a linguistic detour between metaphysical starting and ending points, and raises some worries stemming from this. It then proposes an improved version of the argument, which avoids these (...) worries, and responds to some potential objections to this version of the argument. (shrink)

I first argue that there are many true claims of the form: x-ing would be morally required, if anything is. I then explain why the following conditional-type is true: If x-ing would be morally required, if anything is, then x-ing is actually morally required. These results allow us to construct valid proofs for the existence of some substantive moral facts—proofs that some particular acts really are morally required. Most importantly, none of my argumentation presupposes any substantive moral claim; I use (...) only plausible claims that most moral skeptics and error theorists can and do accept. The final section diagnoses why my arguments work. Here, I offer an explanation for the supervenience of the moral on the non-moral that may help those worried that the strategy is a sophisticated trick. I conclude by considering two objections. In replying to these objections, I explain why the strategy may allow us to demonstrate more than “obvious” moral truths, and why it may also address a stronger version of error theory, according to which, moral truths are not possible.

The overarching aim of this essay is to argue that moral realists should be "causalists" or claim that moral facts of certain kinds are causally efficacious. To this end, I engage in two tasks. The first is to develop an account of the sense in which moral facts of certain kinds are causally efficacious. After having sketched the concept of what I call a "configuring" cause, I contend that the exercise of the moral virtues is plausibly viewed as a configuring (...) cause. The second is to show that the causalist position I develop can withstand objections inspired by the work of Robert Audi and Jaegwon Kim. (shrink)

In this paper I argue that whether or not a world is good can be a contingent fact about the world that is not dependent upon that world's natural facts, or, indeed, upon anyother facts. If so, the property, good, does not supervene upon the facts of nature (or upon any other facts). My argument for this claimis that it is possible to view the very world in which we live (viz. the natural facts that constitute it) as good and (...) to view it as bad. (shrink)

The 'argument from queerness', made famous by J. L. Mackie, remains one of the most influential arguments in metaethics. However, many philosophers focus on just one or two of its strands, while others assume a particular but by no means universal reading of it. This essay attempts to disentangle and evaluate all strands of the argument. Surprisingly, when this is done, not much is left as a distinct argument from queerness. Much of the argument collapses into other types of argument, (...) and what is left, though intuitively appealing, is not viable as philosophical argument. (shrink)

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different moral properties are supposed (...) to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

Jeff Wisdom has recently defended the proposition that any view of moral supervenience worth its salt must incorporate a diachronic view of base property exemplification. Let us call the proposition defended by Wisdom p. In this paper, I try to show that Wisdom has offered no good reasons for accepting p. My argumentative strategy proceeds along two separate tracks. First, I try to show that the thought experiment Wisdom employs in order to underwrite p does not offer the intended support (...) for the proposition. Secondly, I try to show that even if the problems with the thought experiment in question are ignored, there is at least one other reason for thinking that Wisdom has not offered a convincing argument in favor of p.

The aim of this paper is to show that David Brink’s influential version of moral realism cannot give a convincing explanation of moral supervenience. Section twocontains an outline and discussion of Brink’s view of moral properties. Section three explicates Brink’s notions of strong and weak supervenience. In sections four and five, Brink’s explanation of moral supervenience is discussed. It is argued that his functionalist view of moral properties means that the explanation of moral supervenience that he explicitly offers is not (...) satisfactory. A suggestion is also made about what the exact nature is of the explanatory challenge that Brink faces inrelation to moral supervenience. Finally, it is argued that Brink cannot meet this challenge.

Jonathan Dancy thinks that there are irreducibly normative properties. Frank Jackson has given a well-known argument against this view, and I have elsewhere defended this argument against many objections, including one made by Dancy. But Dancy remains unconvinced. In this chapter, I hope to convince him.

Frank Jackson has argued that, given plausible claims about supervenience, descriptive predicates and property identity, there are no irreducibly normative properties. Philosophers who think that there are such properties have made several objections to this argument. In this paper, I argue that all of these objections fail. I conclude that Jackson's argument shows that there are no irreducibly normative properties.

Surprisingly, many ethical realists and anti-realists, naturalists and not, all accept some version of the following normative appeal to the natural (NAN): evaluative and normative facts hold solely in virtue of natural facts, where their naturalness is part of what fits them for the job. This paper argues not that NAN is false but that NAN has no adequate non-parochial justification (a justification that relies only on premises which can be accepted by more or less everyone who accepts NAN) to (...) back up this consensus. I show that we cannot establish versions of NAN which are interesting in their own right (and not merely as instances of a general naturalistic ontology) by appealing to the nature of natural properties or the kind of in-virtue-of relation to which NAN refers, plus other plausible non-parochial assumptions. On the way, I distinguish different types of 'in virtue of' claims. I conclude by arguing that the way in which assessment of meta-ethical hypotheses is theory-dependent predicts the failure of non-parochial justifications of NAN. (shrink)

In this essay I distinguish between a synchronic view of base property exemplification and a diachronic one. I argue that only a diachronic view of base property exemplification can substantiate a ban on morally mixed worlds. I then argue that one of Robert Mabrito’s recent criticisms of Russ Shafer-Landau’s moral realism fails on either a synchronic or a diachronic view.

What is the relation between moral and natural properties? And how do we conceive of this relation? By ‘moral’ properties I will mean properties such as being evil, just or virtuous or having duties or rights; and by ‘natural’ properties I will mean properties such as psychological, sociological and physical properties.1 Suppose we judge that Queen Isabella of Spain was evil in 1492, or at least that many of her actions in 1492 were evil. Then we do not think that (...) she had various natural properties in 1492  such as being a torturer, a bigot and desiring other’s pain  and by an astounding coincidence she or her actions also had the moral property of evil. Rather, we think that she or her.. (shrink)
