 If one is serious about the existence of sums of matter, it seems there are only a few ways they could relate to ordinary  objects.[20]  One way is to say that sums constitute ordinary objects by coinciding with them. That is, sums are distinct objects which share all of their parts with the commonsense objects they make up. One could also eliminate ordinary objects. Ordinary objects either do not exist, or exist in some kind of shadowy or derivative sense (think of ‘the average man’). Another way is to say that while sums are in fact things or objects, ordinary objects are a different kind of entity. These dual-category views hold that commonsense objects are in a different ontological category than sums.
