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.
