The broad aim of this research is to outline, assess and elaborate on Davidson’s work onradical interpretation and its connections to his understanding of values, and particularly onhis understanding of the nature of ethical judgments and concepts.The central idea that I consider is that the principle of charity must play much the same rolein the attribution of values to a speaker as it does in the attribution of beliefs. This is takento show that certain general claims about the content of propositional attitudes, whichDavidson thinks follow from the consideration of radical interpretation, can be applied tovalues as well as beliefs.
