In Abolition of Man, C.S. Lewis opens with a critique of "Gaius" and "Titius" who have written a book - "The Green Book" - on English composition. Lewis observes the authors performing a great disservice to the pupil, failing to teach him virtues and values which certain objects and circumstances in the universe necessarily merit.
a sort of ghastly simplicity we remove the organ and demand the function. We
make men without chests and expect of them virtue and enterprise. We laugh at
honor and are shocked to find traitors in our midst. We castrate and bid the
geldings be fruitful.” Abolition of Man, p.37
