Two full halves

The brain contains two halves: one sensible and therefore  that half is fully cogent, and one not sensible and therefore that half is empty of cogency.  For one side therefore the two halves are empty, dull, but for the other the two halves are full in so far as since both are understood then in spite of a half being incogent it’s cogently so.  But - so - should we conclude that if you add two full halves that gets you a full empty because now doubled and that if you add two empty halves that gets you an empty full or should it be vice versa?  Thus that adding two empty halves will get you a brain sensible but adding two full ones will get you a brain senseless.  This is like the question of the empty sleeve.  Put a glove on it.
