This tribute honors the life and legacy of Dr. John B. Cobb Jr. (1925–2024), a pioneering American theologian, philosopher, and environmentalist who profoundly shaped process theology and the global movement for ecological civilization. As a foremost interpreter of Alfred North Whitehead’s process philosophy, Cobb’s interdisciplinary work bridged theology, ecology, economics, and ethics, inspiring generations across continents. Recognized for his visionary call to preserve planetary life and foster an ecological civilization, Cobb’s contributions include more than 50 books, institutional leadership through the Center for Process Studies, and widespread influence in China and beyond. This dedication commemorates Cobb’s enduring role as a moral and intellectual guide for a more sustainable and interconnected world.
