Wherein lies the solution to the paradox of the barber who says he only shaves those and only those who do not shave themselves?
Let us consider the following scenarios:
Scenario 1: The barber has a son who is not shaved. Does the barber shave the son?
If yes, then the son is shaved, which means the barber does not have a son who is not shaved, a contradiction.
If no, then the son is not shaved, which means the barber has a son who is not shaved, which means the barber shaves his son, a paradox.
