!!! Overview
[{$pagename}] really "Fitch's paradox of knowability"" is one of the fundamental puzzles of epistemic logic. 

[{$pagename}] 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."
