I'm currently reading My Brilliant Friend, the first book in The Neopolitan Novels series by Elena Ferrante. Her writing is beautiful, and I can't wait to finish the series. The passage below is from an interview in The Paris Review, which is interesting in its entirety, but particularly on this point about literary truth:
"The most urgent question for a writer may seem to be, What experiences do I have as my material, what experiences do I feel able to narrate? But that’s not right. The more pressing question is, What is the word, what is the rhythm of the sentence, what tone best suits the things I know? Without the right words, without long practice in putting them together, nothing comes out alive and true. It’s not enough to say, as we increasingly do, These events truly happened, it’s my real life, the names are the real ones, I’m describing the real places where the events occurred. If the writing is inadequate, it can falsify the most honest biographical truths. Literary truth is not the truth of the biographer or the reporter, it’s not a police report or a sentence handed down by a court. It’s not even the plausibility of a well-constructed narrative. Literary truth is entirely a matter of wording and is directly proportional to the energy that one is able to impress on the sentence. And when it works, there is no stereotype or cliché of popular literature that resists it. It reanimates, revives, subjects everything to its needs."
