Abstract
Davidson's theory of radical interpretation, and his principle of charity, are well known in their application to beliefs and meanings, but rarely discussed in their application to desires and values. This is a pity, for they provide the makings of an argument for normative realism that is definitely worth exploring. After introducing Davidson's interpretation argument, I work through some familiar grounds for doubting that it applies to desires and values. Foremost among these are doubts about the extent to which holism is true of desires and about the sense in which values or reasons could be thought to be objective. I conclude that while Davidson does not always address these doubts as thoroughly or as carefully as one might wish, he clearly sees how the argument here has to go, and he has at his disposal plausible responses to a good number of the challenges that are likely to arise.
