“To amuse is not to teach. The object of teaching is to erect a framework of knowledge in a child's mind and gradually to bring the child as near as may be to the average level of intelligence. Later in life the facts taught by experience and new discoveries will add themselves to this framework. It is wrong to attempt to upset this natural order and to appeal to a child's mind by diverting it with the spectacle of modern life. Teaching by means of pictures, radio, and the cinema is in itself ineffective; these methods must not be used unless they involve (and this is possible) some effort or special enthusiasm. That which is learned without difficulty is soon forgotten, and for the same reason, oral instruction which does not require the pupil's personal participation is almost always rather useless. Eloquence slides in and out of young minds. To listen is not to work.”
Naturally this does not apply to the teaching of modern languages.

Context: Teach the child to respect that which is not respectable and you teach the child the first requirement of slavery: submission to unjust authority. Children are persons. They are small persons whose perfect souls have not yet been ground through the meat grinder of slavery.
