This essay addresses how the idea of wilderness is a point of conversation between environmental philosophy and environmental theology. This topic is approached through a conversation with the environmental philosophy of Martin Drenthen. First, I discuss the respective aims of environmental philosophy and environmental theology. Second, I summarise the work of Drenthen on wilderness and otherness. Third, I compare this vision of environmental philosophy and a theological concept of Divine Otherness. Finally I sketch how this exploration is part of a (...) theological account of wilderness. Taking seriously Drenthen's view that wilderness is the otherness at the intersection of nature and culture, wilderness can be understood as indicative of Divine Otherness. Thus wilderness is a unique place where theological and philosophical thinking traverse and challenge each other. (shrink)
