This thesis examines the work of 20th century German philosopher Josef Pieper and reconciles his combination of medieval Christian and ancient Greek thought with modern governance and ethics. The thesis analyzes his collective works as they relate to his chapter on justice in The Four Cardinal Virtues, as well as appropriate references, such as Aristotle's Nicomachean Ethics and Thomas Aquinas's Summa Theologica, to name but two. The aim of this thesis is to study Pieper's understanding of virtue ethics, his conception of justice as a virtue, and his envisioned culture. Chapter I discusses Pieper's understanding of the virtues and prudence's precedence over justice, Chapter II explores his understanding of justice and authority and the implications his theory has for modern government, and Chapter III describes Pieper's envisioned culture according to his conceptual framework. His theory serves as an invitation, as he presents a worldview that draws his audience into a virtuous world. With this understanding, this thesis argues for the merits of Pieper's worldview and explores the intricacies of religious belief's role in realizing his envisioned world. Ultimately, Pieper's argument opposes strict secularism while illuminating the confusion and qualms within the post-Christian West, challenging modern democracy and capitalism from a virtue ethics perspective. This thesis emphasizes Josef Pieper as a social commentator and prompts further discussion into the value of virtue ethics and Thomism.
