B-Brains (SOM Section 6.4)
	Any part of the brain connected not
		to the outside world, but only to another part of the 
		same brain.  Like a manager, a B-brain can supervise
		and A-brain without understanding either how the A-brain
		works or the problems with which the A-brain is involved 
		-- for example, by recognizing patterns of activity that
		indicate the A-brain is confused, wasting time in repetitive
		activity, or focused on an unproductive level of detail
	
	
	
	Papert's Principle (SOM Section 10.4)
	Some of the most crucial steps in mental growth
		are based not simply on acquiring new skills, but on 
		acquiring new administrative ways to use what one
		already knows.
