Style is never simply technical choice, but evolves from how a writer sees the world...(To embrace) a readily identifiable prose style without being aware of its tyranny and inevitability of voice...(is to embrace) a ready-made point of view. Linsey Abrams, "A Maximalist Novelist Looks at Some Minimalist Fiction."
E. Ethelbert Miller asks, "Writers talk about finding their voice? When did you find yours?"
In the late 1960s when I was a Journalism major, I had a professor who was fond of giving his students a copy of a decades-old newspaper article, with the author's name removed, and asking them to identify who wrote it. Just as art history students are tested on recognizing an anonymous painting, and music students on naming a composer based on an unidentified scrap of his music, so too, this professor expected us to determine the newspaper man who did this piece by its style and voice alone. A couple of class members rose to the occasion. (I was one of them but only because I had a friend who took this class before me and told me the answer.) The piece in question was an old news article by Ernest Hemingway. If you knew his fiction, you were certain to recognize the personality and linguistic decisions in this newspaper story.
