    Part of a larger discussion

    Supports→If everyday reasoning involves modal epistemic logics such as S4 or S5, the computational demands on epistemic agents are even more severe than those imposed by classical logic.

    Validity and satisfiability problems for classical propositional logic are already coNP-complete and NP-complete respectively.

    Note, however, that such theorists are typically careful to avoid explicitly asserting that there are only finitely many feasible numbers. g. those given in the formulation of (S2). Certainly the claim that there is a largest feasibly constructible number would invite the challenge that the strict finitist nominate such a number \(n\). And any such nomination would in turn invite the rejoinder that if \(n\) is feasibly constructible, then \(n+1\) must be as well. But in the sort of model \(\math
