英语寓言故事-The Cobbler Turned Doctor

A COBBLER unable to make a living by his trade and made desperate
by poverty, began to practice medicine in a town in which he was
not known.
He sold a drug, pretending that it was an antidote to
all poisons, and obtained a great name for himself by long-winded
puffs and advertisements.
When the Cobbler happened to fall sick
himself of a serious illness, the Governor of the town determined
to test his skill.
For this purpose he called for a cup, and
while filling it with water, pretended to mix poison with the
Cobbler's antidote, commanding him to drink it on the promise of
a reward.
The Cobbler, under the fear of death, confessed that
he had no knowledge of medicine, and was only made famous by the
stupid clamors of the crowd.
The Governor then called a public
assembly and addressed the citizens:
"Of what folly have you been
guilty? You have not hesitated to entrust your heads to a man,
whom no one could employ to make even the shoes for their feet."
