 So far, nothing too surprising; so far, that is, we just have a classic Frege-style case. But let’s continue the story. Sally tries to catch the attention of the person in the phone booth to warn him of the impending danger. She leans out of her window and waves her arms madly, screaming at the top of her lungs. Bill sees someone waving and yelling at him, comes to believe that that person believes of him that he is in danger (although, as he quickly looks around, not seeing the steamroller, can’t imagine why), but doesn’t realize that it is Sally waving her arms. He says to Sally over the phone, “There’s someone waving at me and she believes that I am in danger.” Sally believes what Bill says and so is disposed to accept (40) below.
