This course examines the relationship between spirituality and the human encounter with the environment in history and today. Beginning with an examination of some of the ancient, Medieval and early modern religious foundations of ecology and the environmental movement, the course moves on to focus on contemporary green theology, the practice of religious environmentalism and the interaction between religious traditions and the environmental sciences and technologies. It engages with primary sources from and scholarship about Western (Abrahamic), Eastern (Dharmic) and indigenous religions, along with twenty-first-century green theology, religious environmentalism, ecofeminist perspectives and Dark Green Religion. Grounded in the history of science and technology, this course takes an interdisciplinary approach to its themes, incorporating historical, literary, theological, political, sociological and philosophical perspectives.
