Great selection.
1/ Building on Von Kuehnelt-Leddihn's point: Civilisation itself is not spontaneous and self-sustaining, and its reproduction requires force in the form of artificial and purposeful constraints.
Force is applied by the body-politic against material scarcity and environmental uncertainty, other polities, and its members. Individuals internalise force as constraints, but in concentrated form re-express it into renewed institutional structures. Force acts on human drives, channelling them into constrained action-spaces from which political order emerges.
I've been thinking of this as the "force model of civilisation".
2/ I would add that the "contradiction" of liberal democracy (individual sovereignty + equality claims) is a _constitutive_ tension.
It's a Nietzschean 'tension of the spirit', produced through the sustained channelling and constraining of human drives, which extends the reach of possible action, both generative and destructive.
