 Let’s suppose that this sentence, as uttered by me, is true. Then, if what we said about  (11)  was right, it seems that “I” must, in, (12), refer to whoever it would refer to if it were uttered 100 years in the future. So the one thing we know is that (assuming that (12) is true), it does not refer to me—after all, I won’t be around to utter anything. But, plainly, the “I” in (12) does refer to me when this sentence is uttered by me—after all, it is a claim about me. What’s going on here?
