 Another option for the ‘extreme realist’ about possible worlds is to hold that Clover is four-legged relative to our world, but three-legged relative to some other world. In general, qualities we would normally think of as monadic properties are in fact relations to worlds. McDaniel (2004) defends a view along these lines. A feature of this account is that one and the same entity may exist according to many worlds, for that entity may bear the exists-at relation to more than one world. Accordingly, the view is sometimes called genuine modal realism with overlap (McDaniel 2004). This view, transposed to the temporal case, is precisely what the endurantist says: objects do not have temporal parts; each object is wholly present at each time. (See the separate entry on Temporal Parts.)
