The problem of creeping minimalism concerns how to tell the difference between metaethical expressivism and its rivals given contemporary expressivists’ acceptance of minimalism about truth and related concepts. Explanationism finds the difference in what expressivists use to explain why ethical language and thought has the content it does. I argue that two recent versions of explanationism are unsatisfactory and offer a third version, subject matter explanationism. This view, I argue, captures the advantages of previous views without their disadvantages and gives us a principled and general characterisation of non-representational views about all kinds of language and thought.

In this paper I discuss the so-called problem of creeping minimalism, the problem of distinguishing metaethical expressivism from its rivals once expressivists start accepting minimalist theories about truth, representation, belief, and similar concepts. I argue that Dreier's ‘explanation’ explanation is almost correct, but by critically examining it we not only get a better solution, but also draw out some interesting results about expressivism and non-representationalist theories of meaning more generally.
