 Because Premise (2) is his central focus, Cuneo’s case for metaethical realism largely boils down to a sustained defense of metaepistemological realism (see also here Cuneo &amp; Shafer-Landau 2014). Also, like Boghossian, Cuneo’s case in favor of metaepistemological realism proceeds as a negative case against various forms of metaepistemological anti-realism, including especially error theory and expressivism (see  §1.2  for discussion of these views).
