In James A. Michener's book "Poland," he explores the tension between raw power and the complexities of civilization. The quote "Rampaging horsemen can conquer; only the city can civilize" encapsulates the idea that while strength and aggression can lead to domination, true progress and culture emerge from urban civilization.
The author illustrates how cities serve as centers of culture, law, and social order, contrasting them with the chaos of conquerors. This highlights the essential role of civilization in transforming raw power into a structured society that fosters growth and harmony, emphasizing the importance of urban life in human development.
