The citizens of a certain city were debating about the best material to use in the fortifications which were about to be erected for the greater security of the town.  A carpenter got up and advised the use of wood, which he said was readily procurable and easily worked.  A stone mason objected to wood on the ground that it was inflammable, and recommended stones instead.  Then a tanner got on his legs and said, "In my opinion there's nothing like leather."

Everyman for himself.

That's the lesson Asop gave to the fable.  What do you think is the lesson?
