Civilization is the assimilation of perennial truths and values in all areas of life. Civilization is comprised of those who are allied first and foremost to reality and continual self-improvement, arete as the Greeks put it, or kaizen as the Japanese put it.
Alliances are rooted in enlightened or mutual self-interest, not morality or world peace or progress fantasies. Relationships are based on balance of power, not good versus evil.
Culturally, there is a shared identity and a shared language.
Commercially, there is enough competition to ensure high standards and high quality, but not so much to be mercenary and mafioso, and enough cooperation to ensure efficiency and to prevent spending inordinate amount of time acquiring basic necessities of existence, but not so much that a Kumbayah crowd forms.
Peasants feel no desire for "equality" and "freedom" because they are actually given adequate material needs, not genocided or liquidated.
Kings seek out might and glory by taking actions to ensure the continued survival of their civilization and by doing deeds to immortalize the character of their civilization.
Everything is substance- or result-oriented, not process- or method-oriented. There is zero tolerance for relativism and irrationality. Rule of law, not men, and that law is based in nature, not delusion.
Civilization is simple, but not easy. Most are not fit for civilized life. It requires discipline and courage. Most are lazy, flaky, cowardly, and corrupt. It requires suffering for ideals. Most simply want comfort (status, women, money, machines, toys).
"But what more oft, in nations grown corrupt,
And by their vices brought to servitude,
Than to love bondage more than liberty --
Bondage with ease than strenuous liberty."
- John Milton
