Full Idea
There are numerous cases in which there is pressure to admit coincident entities. The best way of coming to grips with this, I think, invokes the stage view. ...In the worm theory, coincident objects are no more mysterious than overlapping roads.
Clarification
A 'stage' is a 'temporal part'. 'Worm' theory says objects are spread out over time
Gist of Idea
The stage view of objects is best for dealing with coincident entities

A Reaction
At this point I get nervous if in order to 'get to grips' with a phenomenon which is hard to articulate but obvious to common sense, we have to invoke a rather startling metaphysics that completely upends the common sense we started with.
