A philosopher had two hours to
spend in a small town and decided to cut his hair. The town had only two barbers, each one with own
his shop.
The logician entered in the
first barber shop and saw that it was extremely disordered. The barber needed
cut his beard, his clothes were disorderly and his hair was badly cut.
He entered in the other shop and
it was extremely ordered. The barber was freshly shaved, precisely dressed and
his hair was uniformly cut.
The philosopher returned to the
first barbershop for his haircut.
Why? How can you explain this?
