I just completed my undergraduate studies in philosophy from a well-reputed state school and am looking at terminal M.A.s in literature, such as Columbia's program. I'd love to get involved in an editing career for magazines like NYRB, TLS, or Harper's. Would an M.A. in literature set me up to be competitive for careers such as those? I don't have much interest in academia, so I don't think a PhD would serve me well...or would a PhD be necessary for these opportunities?
