The Evolution of Civilizations
Carroll Quigley, a historian who taught at Georgetown, offers a framework for understanding why civilizations grow and fall. He argues that a civilization advances when it has an 'instrument of expansion,' a way of producing surplus and reinvesting it, and that decline sets in when that instrument hardens into an 'institution' that serves itself rather than its original purpose. Quigley lays out stages of mixture, gestation, expansion, conflict, universal empire, decay, and invasion, and applies them across history. The book reflects his broader effort to treat history with method and theory rather than narrative alone, drawing examples from ancient and Western societies to test the pattern. It remains read by students of macro-history and political thought, and it laid groundwork for Quigley's larger study of world history.
