In "The Square and the Tower: Networks and Power," Niall Ferguson explores the evolution of social networks throughout history and their influence on power dynamics. He asserts that modern society can be divided into two distinct groups: those who build and manage the networks, and those who simply engage with them. This distinction highlights the shift in control and authority as digital networks become increasingly central to social interaction and governance.

Ferguson's analysis traces the historical roots of these networks, from secret societies like the Freemasons to contemporary tech giants like Facebook. He emphasizes how the structure and control of networks shape societal hierarchies, influencing everything from politics to economics. By understanding these dynamics, readers are encouraged to consider their own relationship with the networks that dominate contemporary life.
