18. HOW TO LIVE?
The Ant and the Grasshopper
In a field one summer's day a Grasshopper was hopping about, chirping and singing to its
heart's content. An Ant passed by, bearing along with great toil an ear of corn he was taking to
the nest.
"Why not come and chat with me," said the Grasshopper, "instead of toiling and moiling in that
way?"
"I am helping to lay up food for the winter," said the Ant, "and recommend you to do the
same."
"Why bother about winter?" said the Grasshopper; we have got plenty of food at present." But
the Ant went on its way and continued its toil. When the winter came the Grasshopper had no
food and found itself dying of hunger, while it saw the ants
distributing every day corn and grain from the stores they had collected in the summer. Then
the Grasshopper knew:
It is best to prepare for the days of necessity.
—Aesop, 620-564 BCE
