  Arguments for naturalism are lacking in the literature. Most naturalists simply posit their naturalism and work downstream from it, hoping that its consequences will prove attractive to the susceptible (Maddy 2007, 3). Naturalism thus effectively becomes a personal credo with little direct attempt to bring anyone else on board: I accept only X-standards in some domain because I find them more credible than others. Now perhaps at the end of the day one cannot do better. But we shouldn't assume that at the outset. That is all the more important given naturalism's revolutionary features, as explained earlier. A conservative theory of justification might sanction naturalism given a broadly naturalist starting point; but our starting point, as we have seen, is not that of trumping naturalism: it is at most compatibility naturalism. So an argument for anything more than the mildest version of naturalism would be welcome.
