In a village, the barber shaves everyone who does not shave himself/herself, but no one else.
Who shaves the barber?
There is no absolute answer. Ok, so the barber will shave anyone that does not shave him or herself and will not shave anyone else, The barber can not shave himself as that would be someone who shaves themself. Anyone in the village that shaves or does not shave his or herself could shave the barber.The barber may not shave.
