The Collapse of Complex Societies

Tainter reviews some two dozen historical collapses — the Western Roman Empire, the Classic Maya, Chacoan society — and rejects the usual explanations (invaders, resource depletion, moral decay) in favour of an economic one. Complexity is a problem-solving strategy, and like any investment it has declining marginal returns: a society adds administration, infrastructure, specialists and information-processing until each additional increment costs more than it yields. At that point collapse is not a catastrophe visited on the society from outside but a rational economizing move — a return to a lower and cheaper level of organization.

Why it’s on the list: It sits in the curriculum’s history-of-political-philosophy section, which reaches past particular regimes to the question of what sustains a civilization at all; Tainter supplies the cost-side account of why complex orders stop paying for themselves.

Where I saw it: Brendan McCord’s Philosopher-Entrepreneur Reading List, in the section on History of Political Philosophy and the Natural Right Tradition. The entry carries a ☑️ on the source page; the page gives no legend for that mark, so it is recorded here literally and not interpreted. The full 211-entry transcription is on The Philosopher-Entrepreneur Reading List.
