MW: Careful. I said a process (any individual) has identity that is its
spatio-temporal extent. i.e. if two objects have the same spatio-temporal
extent, they are the same object. The same principle applies to sets/types.
two sets/types are the same if they have the same members. (These are 4D
positions of course, and the former at least is not usually held for at
least 3D objects).

MW: I think you are talking about things you have deemed have identity,
not what it is that makes them the same/different which is what I am
talking about.
