Madeleine L'engle said this quote
“ In the final exam in the Chaucer course we were asked why he used certain verbal devices, certain adjectives, why he had certain characters behave in certain ways. And I wrote, 'I don't think Chaucer had any idea why he did any of these things. That isn't the way people write.'I believe this as strongly now as I did then. Most of what is best in writing isn't done deliberately. ”
