I develop an expressivist account of verbal disagreements as practical disagreements over how to use words rather than factual disagreements over what words actually mean. This account enjoys several advantages over others in the literature: it can be implemented in a neo-Stalnakerian possible worlds framework; it accounts for cases where speakers are undecided on how exactly to interpret an expression; it avoids appeals to fraught notions like subject matter, charitable interpretation, and joint-carving; and it naturally extends to an analysis of (...) metalinguistic negotiations.

Pluralism is relevant to conceptual engineering in many ways. First of all, we face the issue of pluralism when trying to characterise the very object(s) of conceptual engineering. Is it just concepts? Could concepts be pluralistically conceived for the purposes of conceptual engineering? Or rather, is it concepts and other representational devices as well? Second, one may wonder whether concepts have only one function in our mental life (representation) or, rather, a plurality of functions (including non-representational ones). Third, it is (...) a contended question whether conceptual engineering projects should pursue only one set of values and goals (epistemic ones) or, rather, a variety of values and goals, including non-epistemic ones. Finally, the engineering of a concept may result in a form of “local” conceptual pluralism, which gives rise to its own ontological and semantic challenges. Having explored the various ways in which pluralism becomes important for conceptual engineers, this contribution presents and summarizes the articles published in this special issue. (shrink)
