 The crucial point is that the second sentence has a reading on which it attributes to Scott a general belief instead of a belief about a particular person. This reading would be true, for example, if Scott believed that some man broke into Sarah’s apartment by coming in the window, but had no idea about who might have broken in. This is (prima facie) evidence that the pronoun in the second sentence is not a referring expression, because if it were, the second sentence of (18) would only have a reading on which it attributes to Scott a belief about the particular person the pronoun refers to. But this is  incorrect.[7]  (On the other hand, for a treatment of such de dicto readings while maintaining that the pronoun is a referring expression, see Elbourne 2005: 99–106.)
