Niall Ferguson's book, "The Square and the Tower: Networks and Power, from the Freemasons to Facebook," explores how significant historical changes often stem from the efforts of loosely structured groups with minimal documentation. He argues that these informal networks, rather than formal institutions, frequently drive social and political transformations throughout history.

Ferguson highlights that the power of these networks is often underestimated, yet they have been pivotal in shaping events and movements. By examining examples from the Freemasons to modern social media platforms like Facebook, he illustrates how interconnectedness plays a crucial role in influencing power dynamics and driving change.
