Did you know?
Fitch's paradox of knowability is one of the fundamental puzzles of epistemic logic. It provides a challenge to the knowability thesis, which states that every truth is, in principle, knowable. The paradox is that this assumption implies the omniscience principle, which asserts that every truth is known. Essentially, Fitch's paradox asserts that the existence of an unknown truth is unknowable. So if all truths were knowable, it would follow that all truths are in fact known.

Yet the apparent role of factivity (in the paradox of knowability) and non-factive analogues in related paradoxes of justified belief can be shown to depend on familiar consistency and positive introspection principles. …
