Executive Summary
Published in 2018, 'The Square and the Tower' by Niall Ferguson is a sweeping historical analysis that examines the eternal struggle between two organizing principles of human society: hierarchies (The Tower) and networks (The Square). Ferguson argues that while historians have traditionally focused on the 'Tower'—visible, top-down structures like kings, presidents, and parliaments—the 'Square'—informal, horizontal social networks—has often been the true driver of revolutionary change. He identifies two great 'Ages of Networks': the first beginning with the invention of the printing press and ending with the French Revolution, and the second beginning in the 1970s with the rise of the personal computer and the internet. The book suggests that we are currently living through a chaotic re-emergence of network power that threatens to dismantle established hierarchical order.

The Danger of Networked Anarchy
