In all the works on pedagogy that ever I read - and they have been many, big, and heavy - I don't remember that any one has advocated a system of teaching by practical jokes, mostly cruel. That, however, describes the method of our great teacher, Experience. She says,
:Open your mouth and shut your eyes
:And I'll give you something to make you wise;
and thereupon she keeps her promise, and seems to take her pay in the fun of tormenting us.
