The Greatest of All Plagues

Political Theorist David Lay Williams has a new book that traces the problem of economic inequality through the thought of many of the canonical thinkers in Western political theory. The Greatest of All Plagues: How Economic Inequality Shaped Political Thought from Plato to Marx (Princeton UP, 2024) explores the thought of Socrates and Plato, Jesus, Thomas Hobbes, Jean-Jacques Rousseau, Adam Smith, John Stuart Mill, and Karl Marx. We often turn to these thinkers and their various works to consider how best to establish political regimes and understand political power. But it is quite difficult to separate economics from politics, since these are both key parts of all societies. 

And this is the thrust of William’s work in The Greatest of All Plagues. We expect to find critiques of economics in Karl Marx or Adam Smith, given the focus of their political thought. But The Greatest of All Plagues demonstrates how vital the economic questions are for all of these western thinkers, and how concerned they each were with the concentration of wealth among the few within a society. This is a key component of the analysis in the book and in our conversation: “economic inequality” is a broad term and encompasses many complexities, but the thrust of the book is that each thinker is particularly concerned about the wealthy and the poor, and the destabilizing impact of a very few having great wealth. This is not to exclude poverty from the analysis, but much attention is often paid to the poor and ways to solve poverty. Scant attention is generally paid to the problem posed by excessive wealth, and the imbalance between those possessing great wealth and the rest of the society, and how this is problematic for political regimes and societies.

The Greatest of All Plagues: How Economic Inequality Shaped Political Thought from Plato to Marx is an impressive exploration of not only the work of these political thinkers, but also of the many scholars who have studied these works and these thinkers. There is much depth to this study, and the reader learns a great deal about the works themselves, the theorist under consideration in each chapter, historical context, and the interrelationship between politics and inequality. Williams is clear that his focus is on economic inequality in political theory, and not other, equally important inequalities. During the course of our conversation, we only touch on the surface of this complex and deep work. It is a worthy subject for investigation and this well-written and accessible book provides the reader with a rich discourse on the reason why we should pay attention to wealth inequality and how it contributes to societal instability, the corruption of character and soul, and how it remains an ongoing threat to justice, democracy, freedom and faith.
