The Blind Man and the Whelp

A BLIND MAN was accustomed to distinguishing different animals by
touching them with his hands. The whelp of a Wolf was brought
him, with a request that he would feel it, and say what it was.
He felt it, and being in doubt, said: "I do not quite know
whether it is the cub of a Fox, or the whelp of a Wolf, but this
I know full well. It would not be safe to admit him to the
sheepfold." Evil tendencies are shown in early life. - Aesop
