In this paper I examine the anthropocentrism evident in key texts by Bataille and Heidegger. Starting with Bataille’s treatment of animality in his Theory of Religion I show how a contrast is drawn between animal experience, which is immediate and immanent (“like water in water”), and human experience, which cannot help but transcend its environment by imposing distinctions. According to Bataille the animal therefore remains unfathomably closed to us. Heidegger, meanwhile, suggests that it is the hand which denotes the crucial difference between human and animal. By means of the disclosive demarcation that the hand makes possible humanity enters a unique and privileged relationship to Being. I argue that both authors assume, without demonstrating, a qualitative difference between human and animal. This starting point might thus usefully be described as an “anthropocentric assumption” in the sense that, although neither author considers human experience to be superior to that of animals, each considers it first‐and‐foremost. 相似文献

Characterized as a “wicked” problem, water shortage in the American West will soon become a reality—due to increasing population, climate change, and decreased flows. Concurrently, water‐centered technologies such as hydraulic fracturing and directional drilling have facilitated the rapid and widespread growth of unconventional oil and gas (UOG) production in the United States. Water markets are increasingly touted as the best, most efficient, and fairest mechanisms for allocating vital and scarce resources. Yet this contention is largely unexplored at the food‐energy‐water nexus, particularly from an environmental justice perspective—where equitable water access for all users is a central concern. We utilize a case study in Colorado's South Platte basin based on 41 in‐depth interviews to show: (1) distortions created in regional water markets as wealthy UOG operators participate in them and (2) ways in which access to water markets becomes blocked for smaller, newer, or water‐poor water users. We also highlight how UOG producers’ presence may inhibit the formation of alternative systems for water exchange. Thus, the participation of UOG operators in Colorado's water markets appears to drive environmental injustice and increased inequity at the food‐energy‐water nexus, rather than facilitating fair or efficient access to water for all users. 相似文献
