In their attempt to develop a nonanthropocentric ethic, many biocentric philosophers have been content to argue for the expansion of the moral community to include natural entities. In doing so, theyhave implicitly accepted the idea that the conceptions of moral duties developed by anthropocentric philosophers to describe the moral relationships that hold between humans can be directly applied to the human/nature relationship. To make this expansion plausible, they have had to argue that natural entities have traits that are similar to (...) the morally relevant traits of human beings. Not only are these arguments often unconvincing, but it seems implausible that thesame moral concepts and principles that govern human relationships also should govern human/nonhuman relationships. Many nonanthropocentric ethics, I argue, are (mistakenly) anthropomorphic.To go beyond this relationship I recommend the development of a nonanthropomorphic biocentric ethic. (edited). (shrink)
