@Merry Andrew,
They are the "skeleton" on how Moral is build...they are the Rules to making rules...
What other function would Moral preserve if not Stability through Evolution to allow complexity to flourish ?
Moral is like the difference between micro and macro management...
There is the State "Roman" Law and then there is Moral...Moral is about micro community management, if you get my metaphor...it still serves a macro purpose.
...without Moral you don´t get to the State Law phase...
(layers upon layers building blocks upon building blocks)
