 Examples of challenges to the existence dimension of realism have been described in previous sections. In this section some forms of non-realism that are neither error-theoretic nor expressivist will be briefly introduced. The forms of non-realism view the sentences of the relevant area as (against the expressivist) truth-apt, and (against the error-theorist) at least sometimes true. The existence dimension of realism is thus left intact. What is challenged is the independence dimension of realism, the claim that the objects distinctive of the area exist, or that the properties distinctive of the area are instantiated, independently of anyone’s beliefs, linguistic practices, conceptual schemes, and so on.
