 There are two metaontological points that someone might be inclined to make here. A relatively moderate point is that it is often so hard to make out on what side of the literal/fictional distinction some discourse falls that arguments of the Quinean kind seldom are well supported. A different point is that there is sometimes — or, in the most radical version of the idea, always — no fact of the matter as to whether some piece of discourse is literal or fictional. It is the most radical point here that is the most closely analogous to what Quine says about the analytic/synthetic distinction.
