Suppose there is a town with just one male barber; and that every man in the town keeps himself clean-shaven: some by shaving themselves, some by attending the barber. It seems reasonable to imagine that the barber obeys the following rule: He shaves all and only those men in town who do not shave themselves.

Under this scenario, we can ask the following question: Does the barber shave himself?

Obviously the "reasonable" rule is unreasonable. Of course he does.

Well spotted, although she might go bankrupt with only one client.

Edit - Nah, still doesn't work.

The front door of the barber's shop is in town. The back room where he sits is not, and he shaves himself.

ATY already gave the right response. Given your supposition, the barber shaves himself and it is wrong to say that it is reasonable to describe this barber by the rule you provide.

What you present is not a paradox. The "rule" you provide, though, would be where a paradox lies.

The town has an underaged barber fits within the description.
