 A number of questions arise in considering McDowell’s argument. It appears to be heavily influenced by Davidson’s remarks about the ongoing nature of interpretation (Davidson 1970, 223;  see 4.2).  However, Davidson appeals to the fact that new evidence—in the form of behavior and environmental context—is always coming in that can force us to revise existing interpretations of an agent. There is no mention of shifting standards, or unarticulated or inarticulable conceptions of rationality. Indeed, the implication is that a stable standard, when taking into account new evidence, can lead to revised interpretations of prior behavior. So McDowell appears to be going beyond Davidson’s own views about the concept of rationality. Indeed, the idea that one is not able to fully articulate a concept in the way suggested by McDowell—that it is in effect ineffable –does not clearly sit comfortably with Davidson’s views about conceptual relativism and rejection of the idea of untranslatable languages (see further the supplement on  Related Issues  (Anomalous Monism and Scheme-Content Dualism).
