 Arguably, this result threatens Dummett’s restricted knowability principle as well. But that depends on whether we have applied the principle to basic statements only. \(p\) is basic, but Dummett’s characterization of truth underdetermines the status of \(Kp\). Perhaps it is basic, since \(Kp\) is not truth-functionally complex. Nonetheless, the issue cannot be resolved without a discussion of \(K\).
