Just as in geography there is a “carrying capacity” or a limit to the amount of resources a piece of land can produce; likewise is there a “carrying capacity” or limit to the ability of humans to unite, co-ordinate and cooperate with other people.
The efficacy, substance and success of union exists in inverse relation to the distance to the individual, I.e. Family, friends, working colleagues, society, nation, etc. The explanation for this correlation is that a relationship which exists at increasing distance from the individual must be mediated with increasingly abstract concepts which significance decreases for each individual with increasing abstraction, thereby reducing the substance, meaning and efficacy of such unions.
Any attempt to bring closer a universal abstract relation to one’s immediate local experience is known in Hegalism as “picture-thinking”, the attempt to capture the whole universal in one shot or picture as it where. Such attempts are an inherently religious quest, supremely exemplified by Christianity where a transcendent universal God is united to a personal and local Jewish flesh.
The “carrying capacity” for union may be simply a neurological limitation of the human brain to be able to process and live by abstract relations instead of concrete, immediate and experienced loyalties.
In order for this “carrying capacity” to be transcended, one must in effect, redesign the human species at the genetic or neurological level. But barring such a radical change to humanity, this carrying capacity accounts for the rise and dissolution of grand unification projects which when it exceeds the limit, collapses into a reactionary tribalistic local dissolution
