 Jackson’s proposal seemingly avoids triviality, because evaluative and descriptive predicates appear to be distinct. However, the detour through language faces significant challenges. One challenge concerns the expressive power of a language like ours: if it is limited, then there seemingly might be ethical differences between states of affairs that are not correlated with descriptive differences expressible in a language like ours (for related worries, see Sturgeon 2009, 73–79). A second challenge questions whether the distinction between description and evaluation is characteristically a distinction in the semantic properties of predicates, as Jackson assumes. On one contrasting view, evaluation might instead characteristically be a pragmatic property of whole speech acts (see Väyrynen 2013b for extended defense of this idea for the case of “thick” evaluation.)
