  The Aviary rightly tries to explain false belief by complicating our picture of belief. But it complicates in the wrong way and the wrong place. It is no help to complicate the story by throwing in further objects of the same sort as the objects that created the difficulty about false belief in the first place. What is needed is a different sort of object for thought: a kind of object that can be thought of under different aspects (say, as “the sum of 5 and 7,” or as “the integer 12”). There are no such aspects to the “items of knowledge” that the Aviary deals in. As with the conception of the objects of thought and knowledge that we found in the Wax Tablet, it is this lack of aspects that dooms the Aviary’s conception of the objects of knowledge too. Like the Wax Tablet, the Aviary founders on its own inability to accommodate the point that thought cannot consist merely in the presentation of a series of inert “objects of thought.”  Whether these objects of thought are mental images drawn from perception or something else, the thinking is not so much in the objects of thought as in what is done with those objects (186d2–4).
