The virtues of endurance -- perseverance, patience, resilience, and constancy -- are central to success in any goal-oriented challenging activity that a person undertakes. Gaining a rich understanding of these virtues requires insights from multiple areas of study, but most treatments of the virtues of endurance to date have remained within narrow disciplinary boundaries. No longer. In this volume, philosophers, psychologists, legal scholars, educational theorists, medical practitioners, military theorists, and theologians have labored together to advance our understanding of endurance. Written with scholars in mind, this volume is nevertheless accessible to students and general readers. This volume is divided into two sections: Explorations and Applications. The first section considers the nature of a given virtue, while the second section showcases the relevance of endurance to important areas of our lives. Taken as a whole, this volume provides a comprehensive overview of this ever-important virtue, offering both a theoretical and practical roadmap to working through challenging activities.
