 Deep ecology, feminism, and social ecology had a considerable impact on the development of political positions in regard to the environment. Feminist analyses have often been welcomed for the psychological insight they bring to several social, moral and political problems. There is, however, considerable unease about the implications of critical theory, social ecology and some varieties of deep ecology and animism. Some writers have argued, for example, that critical theory is bound to be ethically anthropocentric, with nature as no more than a “social construction” whose value ultimately depends on human determinations (see Vogel 1996). Others have argued that the demands of “deep” green theorists and activists cannot be accommodated within contemporary theories of liberal politics and social justice (see Ferry 1998). A further suggestion is that there is a need to reassess traditional theories such as virtue ethics, which has its origins in ancient Greek philosophy (see the following section) within the context of a form of stewardship similar to that earlier endorsed by Passmore (see Barry 1999). If this last claim is correct, then the radical activist need not, after all, look for philosophical support in radical, or countercultural, theories of the sort deep ecology, feminism, bioregionalism and social ecology claim to be (but see Zimmerman 1994).
