Simon Blackburn attempts to answer these questions in the early part of his wonderful new book Ruling Passions (Blackburn 1998). Unsurprisingly, despite my admiration for his book, I think he fails to identify a special feature of desires and aversions that makes them especially suitable for expression in normative claims. For all that he says the desires and aversions he picks out are much like the addict’s desire to take drugs. There are revisions Blackburn could make which would make his account more plausible. However, if he were to make these revisions, then he might just as well abandon his non-cognitivism in favor of a version of non-cognitivism’s close cognitivist cousin: subjectivism.

The idea that there is such an analytic connection will hardly come as news. It amounts to no more and no less than an endorsement of the claim that all reasons are 'internal', as opposed to 'external', to use Bernard Williams's terms (Williams 1980). Or, to put things in the way Christine Korsgaard favours, it amounts to an endorsement of the 'internalism requirement' on reasons (Korsgaard 1986). But how exactly is the internalism requirement to be understood? What does it tell us about the nature of reasons? And where-in lies its appeal? My aim in this paper is to answer these ques- tions.
