 Related undecidedness paradoxes of knowability are discussed in Wright (1987: 311), Williamson (1988: 426) and Brogaard and Salerno (2002: 146–148). The undecidedness paradoxes give the anti-realist even further reason to revise classical logic in favor of intuitionistic logic. When accompanied by a reconstrual of our epistemically modest intuitions, logical space for anti-realism is reclaimed.
