How can environmental philosophy benefit from Friedrich Nietzsche's radical critique of morality? In this paper, it is argued that Nietzsche's account of nature provides us with a challenging diagnosis of the modern crisis in our relationship with nature. Moreover, his interpretation of wildness can elucidate our concern with the value of wilderness as a place of value beyond the sphere of human intervention. For Nietzsche, wild nature is a realm where moral valuations are out of order. In his work, however, (...) we can discern a paradoxical moral concern with this wildness. Wildness is a critical moral concept that reminds us of the fact that our moral world of human meanings and goals ultimately rests on a much grander, all-encompassing natural world. Nietzsche's concept of wildness acknowledges the value of that which cannot be morally appropriated. Wild nature confronts us with the limits of human valuing. Wildness as a concept thus introduces the 'beyond' of culture into the cultural arena of values. (shrink)
