[MD] What is SOM?

"A conventional subject-object metaphysics uses the same four static
patterns as the Metaphysics of Quality, dividing them into two groups  
of two: inorganic-biological patterns called "matter," and social- 
intellectual patterns called "mind."...Everything has got to be object or
subject, substance or non-substance, because that's the primary  
division of the universe.  Inorganic-biological patterns are composed  
of "substance," and are therefore "objective."  Social-intellectual  
patterns are not composed of "substance" and are therefore called  
"subjective."

Is the mind/matter distinction the same as the subjective/objective?
Or are the distinctions the same within MOQ but not within SOM? 
  
[Pirsig, via Steve again]
"So what the Metaphysics of Quality concludes is that all schools are  
right on the mind-matter question.  Mind is contained in static  
inorganic patterns.  Matter is contained in static intellectual  
patterns."

This has always seemed a slip of the tongue to me.  Does anyone else think so?
