This book focuses on applying the thought of Saint Augustine to address a number of persistent 21st-century socio-political issues. Drawing together Augustinian ideas such as concupiscence, virtue, vice, habit, and sin through social and textual analysis, it provides fresh Augustinian perspectives on new-yet somehow familiar-quandaries. The volume addresses the themes of fallenness, politics, race, and desire. It includes contributions from theology, philosophy, and political science. Each chapter examines Augustine's perspective for deepening our understanding of human nature and demonstrates the contemporary relevance of his thought.
