how many proverbs did you need

Intelligence is less often so much overrated as it is oversupplied - in cities.  The intelligent person can do wonders with a tree or field, stream or shelter - wonders unavailable to the stupid.  But there is less the intelligent can do in society extensive and fluid enough - ours - to sort the intelligent and stupid into their own communities.  In competition with peers, the intelligent lose their advantage; in cooperation with peers, they loose their needfulness.
