Scientific Models and Metalinguistic Negotiation

The aim of this paper is to explore the possibility that, at least, some metaphysical debates are ‘metalinguistic negotiations’ (to employ a recent term coined by David Plunkett and Timothy Sundell). I will take the dispute between the dominant approaches of realism and the anti-realism ones (especially Fictionalism) about the ontological status of scientific models as a case-study. I will argue that such a debate may be better understood as a disagreement, at bottom normatively, motivated, insofar as a normative and non-factual question may be involved in it: how the relevant piece of language ought to be used. Even though I will generally assess the prospects for a broadly deflationist approach, I shall outline a sense in which the dispute can be recast as ‘minimally substantive’.
