This is a paradox and therefore has no answer. If the barber does not shave, he would have to shave, and if the barber shaves, then he would not have to shave. This is an example of a self-reference paradox, and is derived from Russell's paradox, which shows that not any collection of elements is a set, in the strict sense of set theory in mathematics.<end_of_turn><eos>
