There is a Western myth that political liberty is a durable construct, arrived at by a process of “enlightenment.” This static view is a fantasy, the authors argue. In reality, the corridor to liberty is narrow and stays open only via a fundamental and incessant struggle between state and society: The authors look to the American Civil Rights Movement, Europe’s early and recent history, the Zapotec civilization circa 500 BCE, and Lagos’s efforts to uproot corruption and institute government accountability to illustrate what it takes to get and stay in the corridor. But they also examine Chinese imperial history, colonialism in the Pacific, India’s caste system, Saudi Arabia’s suffocating cage of norms, and the “Paper Leviathan” of many Latin American and African nations to show how countries can drift away from it, and explain the feedback loops that make liberty harder to achieve.

Today we are in the midst of a time of wrenching destabilization. We need liberty more than ever, and yet the corridor to liberty is becoming narrower and more treacherous. The danger on the horizon is not “just” the loss of our political freedom, however grim that is in itself; it is also the disintegration of the prosperity and safety that critically depend on liberty. The opposite of the corridor of liberty is the road to ruin.
