Barber Paradox (Russell's Paradox) - Back to the Paradoxes
Analogue paradox to the paradox of liar formulated English logician, philosopher and mathematician Bertrand Russell.
There was a barber in a village, who promised to shave everybody, who does not shave himself (or herself).
Can the barber shave himself and keep the mentioned promise?
Edited (better wording?):
In a village, the barber shaves everyone who does not shave himself/herself, but no one else.
Who shaves the barber?
The simple solution is lying in the fact that the barber never promised to shave ONLY people who do not shave themselves. He could shave anyone, including himself.
This way there would not be any paradox at all.
The edited version does not mean exactly the same as the original, after all, since the original didn't say he was excluding anyone who shaved themselves. In fact, the edited version IS a paradox.. or at least, so it seems to me.
