The original position contractarian model of ethical reasoning put for
th by John Rawls has been examined as a basis for an environmental eth
ic on three previous occasions in this journal and in Peter Went's Env
ironmental Justice. In this article, I critically examine each of thes
e treatments, analyzing the proposals offered and identifying their sh
ortcomings. I find a total of seven different proposals in this litera
ture for modifying Rawls' theory to augment its adequacy or as a groun
d for environmental ethics. The diverse difficulties that arise in att
empting to apply Rawls suggest the conclusion that Rawlsian ethics may
not be a suitable foundation for an adequate long-term environmental
ethics.
