 Another possible line is that a sword-stick is not one object, but two objects that share some of their matter. This introduces a category of what one might call Siamese objects. It can be argued, however, that allowing this kind of entity undermines Wiggins’s opposition to those, like Ayers, who think that the concept for reidentifying objects is, or often is, something more generic than sortal concepts; something akin to material body. To see how this may come about, we must consider the rationale for Ayers’s theory.
