 Beall’s insights turn on a number of things: (1) the strength of the independent evidence for true epistemic contradictions, (2) the adequacy of the proposed resolutions to the knower paradox, (3) the question of whether Fitch’s reasoning is ineffective without a resolution to the knower and (4) an interpretation for \(\Box\) and \(\Diamond\) that invalidates the relevant inference (from \(\Box \neg p\) to \(\neg \Diamond p)\) while remaining true to the role played by \(\Diamond\) in the knowability principle. We leave these problems for further debate. But compare with Wansing (2002), where a paraconsistent constructive relevant modal logic with strong negation is proposed to block the paradox.
