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.
