Chapter 6 - Pluralities of Meanings

Summary

The chapter is concerned with a commitment of the logical pluralist: if there are at least two correct logics, then these logics will either involve different logical vocabulary or they will assign different meanings to the shared vocabulary. A central question is how this plurality in meaning can be implemented within a pluralist framework. Pluralists typically endorse claims to the effect that (i) the connectives of the logics have different meanings or (ii) that the notion of validity employed by one logic may be relevantly different from the one employed by the other. A further important question is whether the plurality of meanings is confined to the theoretical level only or whether a corresponding plurality is postulated regarding the extra-systematic counterparts of the logical vocabulary of correct logics. I argue that both connectives pluralism and consequence pluralism are implausible when construed as pluralistic theories. Meta-contextualism–the view that the question of whether the meaning of the logical terminology is the same or different in different contexts is itself subject to semantic variability–is shown to have exceedingly radical implications.
