They have not read enough literature to be taught by it how to read it

You only have to teach literature to realise that most young readers are poor noticers. I know from my own old books, wantonly annotated twenty years ago when I was a student, that I routinely underlined for approval details and images and metaphors that strike me now as commonplace, while serenely missing things which now seem wonderful. We grow as readers, and twenty-year-olds are relative virgins. They have not read enough literature to be taught by it how to read it.
