An Erroneous Argument for Error Theory

Abstract

In Cowie’s “Why Moral Paradoxes Support Error Theory,” he argues that recent work in moral theory shows that error theory fares no worse than other metaethical theories when it comes to ordinary moral judgment, and he argues that this suffices to answer the fundamental challenge for error theory. This article shows that Cowie’s argument does not work. More specifically, it is shown that the counterintuitive implications of error theory dominate those of realism, in both a technical, quantitative sense, and in a non-technical, qualitative sense. If Cowie is correct that, in the absence of an answer to the fundamental challenge, error theory should be rejected out of hand, then this constitutes a serious setback to the error theorist’s program.
