A View of Civilization's Reasons to Exist

I've been writing a simplified description of our Collective Understanding of Civilization. So far it's in several separate links at my other site:

Part 1 - Basic premise: People are self-centered or group-centered
Part 2 - Roles and Balance
Part 3 - Conventions and Group Identification
Part 4 - Liberty vs. Equality vs. Property

More will follow. Please stay tuned.
