Fitch's paradox
Fitch's paradox of knowability is one of the fundamental puzzles of epistemic logic, proposed by Frederic Fitch in 1963.
The paradox contradicts the widely accepted knowability thesis, which states that any truth is, in principle, knowable. It concludes instead, that there are some truths that it is not possible to know.
