 A potential threat to Delegation comes from Pickup (2016: 260), who considers the possibility of a complex entity that is exactly located somewhere despite the fact that none of its proper parts is exactly (or weakly) located anywhere. One route to such entities (not Pickup's) runs as follows: (i) some material objects (electrons, maybe) do not have any other material objects as proper parts, (ii) any such material object is a complex entity whose only proper parts are universals, (iii) all material objects have locations, but (iv) no universals have locations. Bundle theorists who are platonic realists about universals, and who take the constituents of a given bundle to be parts of that bundle, will face pressure to accept (i)–(iv) and hence to reject Delegation. The same basic idea is discussed in connection with the Burying Strategy in Section 4.1 below.
