But you can't PRECISELY define the category, or what you want to reason 
about, so your logic is worthless as it is baseless.

Then DEFINE what you are working on.

You already admitted that you category as you initialy defined it wasn't 
the category you actually meant, as you needed to add restrictions not 
stated.

Note, to define HERE, you can't refer to papers not mentioned in the 
problem statement as defining what you are talking about. That is the 
path of lies and desception.
