Abstract

Disputes about logic are commonplace and undeniable. It is sometimes argued that these disputes are not genuine disagreements, but are rather merely verbal ones. Are advocates of different logics simply talking past each other? In this paper we argue that pluralists (and anyone who sees competing logics as genuine rivals), should reject the claim that real disagreement requires competing logics to assign the same meaning to logical connectives, or the same logical form to arguments. Along the way we argue that ascriptions of logical form, as well as connective meaning, are always theory-relative.
