 The problem with Fitch’s reasoning is not with either of the epistemic inferences A or B. Though some have argued that knowing a conjunction does not entail knowing the conjuncts (Nozick 1981), Williamson (1993) and Jago (2010) have shown that versions of the paradox do not require this distributive assumption. And questions about the factivity of \(K\) may be defused rather quickly, since related paradoxes emerge replacing the factive operator “It is known that” with a non-factive operators, such as ‘It is rationally believed that’ (Mackie 1980: 92; Edgington 1985: 558–559; Tennant 1997: 252–259; Wright 2000: 357).
