This book is intended to serve as an introduction to the thought of James V. Schall, arguably one of the best, perhaps even the only, authentically Thomistic political scientist writing today. In contrast to main currents in contemporary Thomism, Schall remains conversant with the great tradition of political philosophy and therefore appreciates the complex and relatively imprecise nature of political reflection. In this book, the distinguished theorist addresses a wide range of subjects, including the question of overpopulation, the thought of Charles McCoy and Leo Strauss, the role of Christianity in political philosophy, and the challenges that the democratic project pose to human beings' perception of the truth. As a meditation on practical and theoretical political questions, self-consciously proceeding from the perspectives of both nature and grace, the book provides a unique picture of what a genuine Thomistic political science might look like.
