 On this picture, the impression of a single choice point between “admitting” and “rejecting” naturalness is misleading: the true theoretical landscape is quite intricate. Moreover, even the most “sceptical” positions do not seem to have much of an anti-realist flavour. There is no obvious way to argue from the claim that there are extensive failures of co-satisfiability between the various alleged roles for naturalness, or from the claim that ‘natural’ and ‘perfectly natural’ are highly vague, to some controversial claim of mind-dependence or relativity. Theories about naturalness provide ways of sharpening and fleshing out what Lewis  (1984, 228)  calls “the traditional realism that recognises objective sameness and difference, joints in the world, discriminatory classifications not of our own making”. But the ideas discussed in this article do not seem particularly helpful for making any nontrivial sense of the competing vision, on which questions of similarity and classification are in some systematic way “subjective” or “up to us”.
