By and large, metaethicists have focused on descriptive questions about the nature of our moral discourse. For instance, is it in the business of stating facts, or of expressing affective states? If the former, are there such facts? If the latter, how is this reconciled with the role that moral language plays in reasoning?…

There is one clear exception. Some who are interested in error theory have shifted their attention from the descriptive question to a prescriptive/ practical one–namely, “Are we to retain moral language? And if so, how are we to treat it?” (I give the practical variant since it might be thought problematic for an error theorist to ask a question framed in terms of “should.”) The reason for this shift is that the prescriptive/practical question seems quite pressing in the case of error theory. Error theory seems to force the question. The two most prominent answers discussed by error theorists, to my (limited) knowledge, are eliminativism and moral fictionalism (of the prescriptive variety).
