Abstract
While the meta-ethical error theory has been of philosophical interest for some time now, only recently a debate has emerged about the question what is to be done if the error theory turns out to be true. This paper argues for a novel answer to this question, namely revolutionary expressivism: if the error theory is true, we should become expressivists. Additionally, the paper explores certain important but largely ignored methodological issues that arise for reforming definitions generally and with a vengeance in the context of a radical error theory about all practical normative judgements, and suggests how these issues can be resolved
