This book promotes a social justice approach that emphasizes social relations, human desires, and lifestyles, demonstrating that Saint Augustine’s thinking is still relevant today when reflecting on ethical choices that allow the permanence of social bonds. It also investigates the conceptual underpinnings of social justice in modern and contemporary political philosophy, drawing on ideas from Machiavelli, Arendt, Polanyi, and Foucault, as well as Western Marxist and Postmodern perspectives, to emphasize the significance of Augustine’s ethics.The complexity of 21st century social and economic problems necessitates a thorough reworking of conceptual political philosophy outlooks in a context of unprecedented political and environmental concerns. This book will result in significant progress toward a philosophy of social justice by renewing the relationship between political life and ethical choices oriented to social well-being. To address social justice, we must be able to reinterpret social challenges from new perspectives. The dialogue between Saint Augustine and relevant political philosophers allows for a discussion that may lead to the development of new frameworks and answers. This book certainly prepares the reader for current, real-world social justice debates.
