I did not say that a statement like 'the cat is on the mat' is about a 
model of reality instead of about reality itself.  Quite the opposite: 
it is about reality, and that's why I would consider it a model of 
reality (and not of a model thereof).    (02)

While I agree that the term 'model' is quite ambiguous (unless precisely 
defined in the context at hand), I still see nothing wrong in saying 
that what you say about the world is a model of the world.  If the term 
'representation' were used instead, would you object as well?
