 Defenders of the standard account make various responses.  Regarding the ‘too many objects’ accusation, some point out that perdurantists require even more objects when you count up all the temporal parts, some attempt to establish principled limits on how many objects are required, and others simply accept the multitude.  After all, it’s not so bad having all those objects when you realise they don’t all need separate locations. The response to the objection about mass turns on an analogy with ordinary parts and wholes: your various internal organs and limbs weigh several kilos each, but we wouldn’t expect these to show up on the scales in addition to your total body mass, since you are made of the same stuff as your organs and limbs. Likewise, supposedly, although the lump and the statue are distinct 1kg objects, we shouldn’t expect these to show up separately on the scales, since they are made of the same stuff.
