  There is another possible practical difference between the two. This comes out when we consider two pretty similar cases of which we nonetheless want to make different judgements. Nobody supposes that this is impossible. The question is rather what is rationally required of the judge in such a case. The generalist might end up demanding that one make the same judgement in both cases unless one can provide a principle that distinguishes them. The particularist, by contrast, might demand only that one make the same judgement in both cases unless one can offer some reason for not doing so. Some, however, would not even demand that. All agree that there must be some relevant difference between any two cases of which one wants to make different judgements.  Might it be enough to allow that there is some such difference, even though one has no idea what it is? Or is one rationally required to be able to make some suggestion about what it is? Or is one’s suggestion to be formulated as a possible principle governing all similar cases?  Particularists might be distinguished from generalists by their answer to these questions.
