 Importantly, the characters of the pure indexicals are supposed to be insensitive to speakers’ mental states. That rules out any possibility of my using the term ‘I’ to refer to Barack Obama. Nor are your and my utterances of (8) predicted to assert the same thing. What’s more, as Kaplan points out, the view allows us to productively distinguish between ‘metaphysical’ necessity and what Kaplan calls ‘logical’ necessity. The sentence “I am here now,” Kaplan claims, represents a logical necessity: in virtue of what the indexicals ‘I’, ‘here’, and ‘now’ all mean, this sentence cannot be uttered falsely. Yet clearly it is not necessary in any sort of metaphysical sense that a particular speaker must be wherever she happens to be at the time of utterance; she could just as easily have been somewhere  else.[7]
