All the men in a village either shave themselves or are shaved by a barber (himself a man from the village).
The barber claims to shave only the male villagers who do not shave themselves.
So who shaves the barber?
Please explain in very simple ways .

A Possible Answer:
A Barber! There could very well be more than one in the village.
A simple explanation of the underlying paradox is
that it is the same as asking "can there be a book in a library that lists all the books in the library that do not contain any lists?"
If the said book contains such a list it should not be listed while if it does not contain such a list it should - paradox.
Formerly, and slightly more strict, as will become apparent: "if R is the set of all sets that do not contain themselves does R contain itself or not?" (the Russell paradox).
A problem posed in the form of such a paradox can have a solution if
It is phrased like the informal example above. The book may be the only book in the library and contain some other list - it is then true, in a sense, that it lists all the books in the library that do not contain any lists.
But for the problem, as posed, this attack does not work.
A possible solution, albeit an admittedly weak one, to the problem, as posed, is
that the barber shaves himself or someone else shaves him or neither or both.
The barber is from the village. The barber has moved to a town, where he works as a barber. All the men in the village that the barber is from who do not shave themselves go to the town to be shaved by the barber.
The barber shaves himself. He can do so without breaking the rules provided that his "claim" is false.
