 First, however, it will be useful to clarify how we are using these terms. It is contentious what, for a given subject matter α, realism, vis-à-vis α amounts to. One generally accepted idea is that an α-realist takes α-claims to be validated by the way things stand in the world (Blackburn 1993). In the epistemic case of interest here, realism implies that attributions of, e.g., knowledge, justification, epistemic virtue and epistemic vice are validated by how things stand in the world. Compare here with the metaethical realist (e.g., Shafer-Landau 2003) who takes attributions of rightness, goodness, moral virtue and vice to be so validated. Likewise, just as the metaethical anti-realist denies that moral claims have this kind of status, the metaepistemological anti-realist will deny the same vis-à-vis epistemic claims, in at least one of two ways: either (i) by denying that there are any epistemic facts (metaepistemological non-cognitivists and error-theorists fall into this category of anti-realism). Or, alternatively, metaepistemological anti-realists might (ii) grant that there are epistemic facts while denying that the obtaining of these facts is independent of anyone’s beliefs, linguistic practices, conceptual schemes, and so on. Here we may locate metaepistemological idealism, constructivism, subjectivism, and relativism (for discussion, see Miller 2002 [2019]; Cuneo 2007; Carter 2016; Baghramian &amp; Carter 2015 [2021]).
