 Suppose that Bob Smith utters (10). Smith’s use of ‘I’ tells us nothing about how Alice represents Smith; in particular, it does not refer to or otherwise involve anything that we would ordinarily call the sense of ‘I’. (It would be strange indeed if what made the attribution true was Alice’s standing in the belief relation to a proposition containing the first-person mode of presentation associated with ‘I’ and the semantic value of ‘will solve an important problem in physics’. If there is such a first-person mode of presentation, then this is what it is for Alice to believe that she herself will solve an important problem in physics, which is not what Smith was saying in uttering (10).) Call this the problem of indexicals. (There is a large literature on this problem. A first wave of important work on the problem include Castañeda 1966,1967. 1999, Chisholm 1981, Evans 1982, especially chapters 6–7, Frege 1956, Lewis 1981, Perry 1977, 1979, Stalnaker 1981. For more recent important papers, see: Cappelen and Dever 2014, Garcia-Carpintero 2013, 2017, Magidor 2015, McKay 1986, Perry 1997, 1998, 2001, Recanati 2007.)
