I've been reading Steven Pinker's new book Sense of Style, and I've noticed that contemporary literature seems to subscribe to some very different notions about stylish prose than writers of the 19th century did. For instance, if you look at The Turn of the Screw by Henry James, the writing style is the antithesis of what most modern writing books prescribe--short, simple sentences that lack adverbs of any kind, etc. So, I'm wondering where the modern style originated. Was Hemingway the first to write in the modern style? Is that why he's sometimes referred to as the great American author?
