A Mole, a creature blind from birth, once said to his Mother:
"I am sure than I can see, Mother!" In the desire to prove to him
his mistake, his Mother placed before him a few grains of
frankincense, and asked, "What is it?"
The young Mole said, "It is a pebble."
His Mother exclaimed: "My son, I am afraid that you are not
only blind, but that you have lost your sense of smell."
(Translated by George Fyler Townsend, 1814-1900)
