biggest regret with the paradoxes video is that I should have spent like one more sentence explaining the barber paradox because a lot of people somehow completely missed the paradox part of it and just said stuff like "uh why doesn't someone else shave the barber"
common "solutions" to the barber paradox ("in a town where everyone must be shaved and there's one barber who shaves those and only those who do not shave themselves, who shaves the barber?")
someone else shaves the barber (that would make the barber someone who does not shave themself, which would mean the barber shaves them)
the barber shaves themself (this would make the barber someone who shaves themself, which would mean they aren't shaved by the barber)
the barber is shaved by a different barber (a different barber still counts as a person.)
the barber is shaved by a razor and not a person (if this counts as not shaving themself then nobody in this town is being shaved by the barber and this does not actually fit any part of the scenario described)
the barber is a woman (women actually count as people so she still needs to be shaved)
the barber is bald (bald people are people too.)
the barber isn't shaved at all (the barber is also a person)
The correct answer is that the barber goes into a closed private room and comes out shaved. The Paradox Police know one of the rules must have been broken. They just don’t know which one. So they can’t make an arrest.
Looks like this corrupt government is gonna have to find another grounds to arrest him. And hey look there’s this incident with a hotel and some money’s left unaccounted for….. perfect excuse to jail an enemy of the state.
The story of the incident never included the barber in any of the tomfoolery, but changed were made as the story was gossiped about. Characters and events were forgotten and replaced with new ones until no elements of truth remained. Is it still the same rumor?
The barber is arrested for this fake story. They take him in. Now, cops are allowed to lie, but if all they do is lie then the barber is safe believing the opposite of what they say. The cops grill him by playing the role two opposite characters— truth cop and lie cop, and the barber isn’t told who’s who. Luckily the cops are kinda dumb and don’t realize that if they answer ask questions this makes it trivially easy for the barber to figure out who to ask for an attorney. Soon, he’s slated for trial
The judge doesn’t care if the story’s fake as long as the prison pays them. Many call this place tyrannical. But at what point in adding unjust laws, one by one, does a government become a tyranny?
Back to the barber though, he’s through with it. He’s making a daring escape. Because the cops have no idea what he’s got in his pocket.
Or wait he shaves part of his beard—no that that doesn’t work either
