the following paradox is a variation of the Barber Paradox, I don't quite understand why this is a paradox so I'd like to hear you tell why, please.
There was a philosopher who had committed a crime (for example, he stared at a King's espouse) and he will be executed. The Benevolent King, though, allows the philosopher to choose if he wants be hanged up or beheaded, he only needs to tell a truth or a lie. The philosopher, then, says: I'll be beheaded.
I'm lost, read this several times and couldn't find the paradox. I appreciate any help.
