Fitch's paradox of knowability is a puzzle of epistemic logic.It provides a challenge to the knowability thesis, which states that every truth is, in principle, knowable.. The paradox states that this assumption implies the omniscience principle, which asserts that every truth is kno
Counterfactuals are context dependent and vague. For example, either of the following statements can be reasonably held true, though not at the same time: [20] If Caesar had been in command in Korea, he would have used the atom bomb.
