Radio and TV aren’t audio-visual aids to enhance or to popularize previous forms of experience. They are new languages. We must first master and then teach these new languages in all their minute particularity and riches. In so doing we have available on an unprecedented scale the resources of comparison and contrast. We can compare the same play or novel or poem or news story as it’s changed artistically in passing onto the movie form, the stage, the radio and TV. We can note the precise qualities of each medium, as we would compare the the various degrees of effectiveness of a thought in Greek or French or English. This is what the young are doing sloppily and helplessly outside the classroom every day. This holds their attention automatically as the classroom does not.
