The chapter argues that we should draw the line between realist and antirealist metaethics according to whether a theory locates the explanation for the special, puzzling features of moral terms and concepts out in the world, with the content of moral thoughts, or inside the head. This taxonomy places Mackie's error theory in the realist category, contrary to the usual scheme. The paper suggests that in looking for the “queerness” of objective value in the metaphysics of moral properties, Mackie makes a mistake parallel to a fantastic mistake made by some of the characters in E. B. White's Charlotte's Web.

Normative theorists like to divide normative theories into classes. One special point of focus has been to place utilitarianism into a larger class of theories which do not necessarily share its view about what is alone of impersonal intrinsic value, namely, individual human well-being, but do share another structural feature, roughly its demand that each person seek to maximize the realization of what is of impersonal intrinsic value. The larger class is distinguished from its complement in two apparently different ways. Let us look briefly at these two ways.

Internalism says that if an agent judges that it is right for her to φ, then she is motivated to φ. The disagreement between Internalists and Externalists runs deep, and it lingers even in the face of clever intuition pumps. An argument in Michael Smith's The Moral Problem seeks some leverage against Externalism from a point within normative theory. Smith argues by dilemma: Externalists either fail to explain why motivation tracks moral judgment in a good moral agent or they attribute a kind of fetishism to good moral agents. I argue that there are alternative models of moral motivation available to Externalists, in particular a model according to which a good moral agent is one who is effectively regulated by a second order desire to desire to do what is right.

In 1971, Simon Blackburn worked out an argument against moral realism appealing to the supervenience of the moral realm on the natural realm.1 He has since revised the argument, in part to take account of objections,2 but the basic structure remains intact. While commentators3 seem to agree that the argument is not successful, they have not agreed upon what goes wrong. I believe this is because no attempt has been made to see what happens when Blackburn's argument is addressed to particular varieties of moral realism. As I see it, we must look to these various brands if we want to understand just where the concept of supervenience can be usefully employed.

1. In ‘A problem for expressivism’ Frank Jackson and Philip Pettit argue ‘that expressivists do not have a persuasive story to tell about how ethical sentences can express attitudes without reporting them and, in particular, without being true or false’ (1998: 240). Briefly: expressivists say that ethical sentences serve to express non-cognitive attitudes, but that these sentences do not report non-cognitive attitudes. The view that ethical sentences do report non-cognitive attitudes is not Expressivism (and not non-cognitivism), but rather a version of cognitivism. According to (what we’ll call) Subjectivism, a typical ethical sentence like ‘Abortion is wrong’ reports the speaker’s non-cognitive attitude toward abortion; it says, in effect, that abortion is the object of some attitude of the speaker’s. Expressivists, by contrast, say that the sentence expresses a non-cognitive attitude toward abortion, but does not say that the speaker has it. Ayer put it this way: I can say that I am bored by uttering the sentence ‘I am bored’, but I can express boredom, without saying that I am bored, by yawning (Ayer 1952: 109).

Many philosophers, in different areas, are tempted by what variously goes under the name of Contextualism, Speaker Relativism, Indexical Relativism. (I’ll just use Indexical Relativism in this paper.) Thinking of certain problematic expressions as deriving their content from elements of the context of use solves some problems. But it faces some problems of its own, and in this paper I’m interested in one in particular, namely, the problem of disagreement. Two alternative theories, tempting for just the same kinds of expressions as Indexical Relativism is meant to handle, promise to solve the problem of disagreement. I’ll argue that they do not live up to their promise. At the end of the paper, I’ll ask what exactly disagreement amounts to, and I’ll canvass some purported solutions.
