Argument-giving reasons for a view-is our model of rational dispute resolution. Fogelin suggests that certain "deep" disagreements cannot be resolved in this way because features of their context "undercut the conditions essential to arguing" . In this paper we add some detail to Fogelin's treatment of intractable disagreements. In doing so we distinguish between his relatively modest claim that some disputes cannot be resolved through argument and his more radical claim that such disputes are beyond rational resolution. This distinction, along (...) with some ofthe detail we add to Fogelin's treatment, sheds some useful light on the project of informal logic. (shrink)
