For we let our young men and women go out unarmed, in a day when armour was never so necessary. By teaching them all to read, we have left them at the mercy of the printed word. By the invention of the film and
the radio, we have made certain that no aversion to reading shall secure them from the incessant battery of words, words, words. They do not know what the words mean; they do not know how to ward them off or blunt
their edge or fling them back; they are a prey to words in their emotions instead of being the masters of them in their intellects….
For the sole true end of education is simply this: to teach [people] how to learn for themselves; and whatever instruction fails to do this is effort spent in vain.
– Dorothy Sayers, The Tools of Learning
