 Opponents of the standard account make the following objections: it requires just too many objects (a particular problem in vague cases, see  section 5);  it entails that when a 1kg statue is constituted by a distinct 1kg lump, the result ought to weigh 2kg; and, most seriously, it fails to explain how two distinct objects, made of the same parts and matter, arranged in the same way and at the same place and time, can be distinct objects with different properties. How could all these facts about the arrangement of parts fail to fix the facts about the whole?
