I'm preparing for my second round of applications for Literature Ph.D. positions in the field of Modernism. Last time, my writing sample was a lightly edited version of a well-received paper I'd written on Virginia Woolf. This year, I'd been planning to compose a new paper on Woolf: she's far and away the writer I'm most grounded in, but my old papers tended to rely far more heavily on close readings than theoretical framework. I expect (though correct me if I'm wrong!) that a solid theoretical grounding is one of the most important things to demonstrate in the writing sample, so am happy to write a largely fresh paper. Starting to look into the Woolf criticism, though, my ideas seem insufficiently different from a lot of the extant thought, and with such a major author, that seems to be true about any of the really sound ideas I could develop.
So would it be better to scrap the Woolf paper, and write on an author who I'm less familiar with, but would be a fresher voice upon? Or should I write the paper that would be well-developed and reflective of my most knowledgeable area, but which represents a rather stale critical voice?
I appreciate any opinions offered!
