 Perry explains his change in behavior by saying “I came to believe that I was making a mess”. As Perry frames the problem, no substitution for “I” in the reported belief (“that I was making a mess”) will preserve the explanatory power of the belief attribution. Descriptive substitutions won’t work, nor will “I came to believe John Perry was making a mess”. What’s reported isn’t a belief in any of the familiar, tractable, Simple-Picture-friendly categories: it’s not a descriptive belief about the F, and it’s not a de re belief about a particular individual. So we need something additional to capture the doxastic state Perry reports himself as coming to be in when he says “I came to believe that I was making a mess”.
