 For instance, according to Baker’s (2000, 2007) constitution view, (P3) should be rejected, since “thinking being sitting in your chair” is ambiguous as between the constituted person who thinks nonderivatively and the constituting human animal who thinks derivatively  (section 2.3).  And Noonan (1998, 2001) also detects an ambiguity in (P2) and (P3). According to his revisionist view of personal pronoun use, first-person thoughts and utterances refer only to persons, not to animals. On his view, we must distinguish between the referent of first-person thoughts and utterances, on the one hand, and the thinker of those thoughts and utterances, on the other hand. Noonan does not deny that the human animal sitting in your chair is capable of first-personal thinking. Nor does he deny that such thoughts (and the utterances that express them) successfully refer. But he does insist that, when the animal has a first-person thought or utters ‘I’, that thought or utterance refers not to the animal who thinks the thought but to the person with whom the animal shares its thoughts. (For further discussion, see Noonan 2012 and Olson 2002a, 2007: 37–39.)
