  One final sort of worry about the distinctiveness of non-cognitivism is worthy of mention. This worry is that if too many domains of discourse are such that they require non-cognitive analysis, the contrast between cognitive and non-cognitive domains on which the view depends will be hard to sustain. Blackburn, for example, suggests quasi-realist approaches not just to moral discourse, but also to modality, causation and probability. One may wonder what he means to deny about these domains that is not also applicable to the rest of our seemingly contentful judgments (Rosen 1998).  This kind of collapse is in danger of assimilating the putatively cognitive and the putatively non-cognitive from the other  direction – by making the former look more like the latter, rather than the other way around as with the worries about minimalism. Even Blackburn himself on occasion expresses worries about this problem (Blackburn 1993, 34), but more commonly he and other non-cognitivists resist the worry by pointing to other domains of discourse which are not amenable to non-cognitivist analysis.
