[MD] Social level for humans only

[craigerb at comcast.net]

Mammal motherhood is all about nuturing & a major component of nurturing is-- 
to use the buzz-word--"socialization" of the infant.
(Report card "citizenship" grade: "Works & plays well with others".)
But if you think of the 3rd level as the "Institutional Level",
then you're less likely to attribute it to rats & bees.
Consider the alpha male in a gorilla troop & the commander of a calvary troop:
If you defy the alpha male, you get your butt kicked.  If you defy the commander,
you get thrown in the brig & the guards kick your butt.
If this were the only difference, they would be on the same level.
But IMHO Pirsig noticed something more; something to do with, possibly,
normative rule-governed behavior.
