Culture
Culture is a core concept in metaculture, as one can imagine.
When used in this wiki, Culture is meant to include all of the primary influences, beliefs, traditions, art, ritual, religion, political beliefs, etc. that contribute to what makes any group of people unique.
Culture can be defined on many levels. Nations, cities, religions, political parties, corporations, music fans, sports teams--any group of people with something in common can create a common expression of culture.
metaculture seeks to create a universal common culture based on a culturally neutral ethical framework and creation story. Not a monoculture that suppresses the unique and varied cultures of the world, but a common cultural language that allows for in-group identification despite different nationalities, religions, or other major cultural touchstones.
