"What an excellent thing is knowledge," said a sharp-looking, bustling little man, to one who was much older than himself.
"Knowledge is an excellent thing," repeated he.
My boys know more at six and seven years old than I did at twelve.
They can read all sorts of books, and talk on all sorts of subjects.
The world is a great deal wiser than it used to he.
Everybody knows something of everything now.
Do you not think, sir, that knowledge is all excellent thing?
"Why, sir," replied the old man, looking grave, that depends entirely upon the use to which it is applied.
It may be a blessing or a curse.
Knowledge is only an increase of power, and power may be a bad, as well as a good thing.
"That is what I can not understand," said the bustling little man. "How can power be a bad thing?"
"I will tell you," meekly replied the old man;
and thus he went on，When the power of a horse is under restraint,
the animal is useful in bearing burdens, drawing loads, and carrying his master;
but when that power is unrestrained, the horse breaks his bridle, dashes to pieces the carriage that he draws, or throws his rider.
"I see!" said the little man.
