Making Peace In and With the World: The Guelen Movement and Eco-Justice is a representative study and working analysis of contemporary Islamic thought on eco-justice. It cuts through problems facing humanity today, ranging from inequality and violence in the smaller globalized world to "the end/death of nature" as signaled by various environmental and ecological crises. Addressing these problems, this volume sheds light on two dimensions of peace in the earth community - making peace between differing human communities, and making peace between humanity and nature. The phrase Eco-Justice in this volume signifies this dual reality, thereby offering a unique and insightful view that justice in the world must go hand in hand with ecological justice if "peace" is to be made.With its dual foci of peace, this volume contributes to multi-disciplinary academic areas. It adds to a burgeoning field of religious ecology, by exploring the dynamics at play in the interaction between religion, human communities and nature, and by providing natural scientific works with considerable theoretical, philosophical and ethical implications. This volume also corresponds to studies in the interdisciplinary field of "war and peace." Since it deals centrally with the question of religion and eco-justice, this volume challenges assumptions of exclusivist religion, religion-oriented violence and the religion-based "Clash of Civilizations."The contributors of this volume from diverse academic backgrounds take Guelen and the Guelen movement as the case study. Muhammed Fethullah Guelen is one of the most significant Islamic theologians in the contemporary world, and his inspired Guelen movement is the fastest growing Islamic civic movement worldwide. This volume provides a key reference to studies in Guelen and his movement for new discussions and criticisms. And, by taking this figure and his movement as a case, it reveals a new dimension of peace among differing human communities and between humanity and nature.
