You also need to not include any axioms that one of the proponents 
would consider to embody a type error, such as applying any kind of 
temporal part function or property to a continuant (a type error for 
an endurantist), or stating a property of a 4-d history relative to a 
time (a type error for a perdurantist).

>I think I'm close to that with Matthew.

Like I said, your latest axioms embody the perdurantist point of 
view, and Matthew is a perdurantist, so that is not surprising. Try 
keeping Matthew *and* Barry Smith happy at the same time.
