Temporal externalism, conceptual continuity, meaning, and use

Abstract

ABSTRACT Our ascriptions of content to past utterances assign to them a level of conceptual continuity and determinacy that extends beyond what could be grounded in the usage up to their time of utterance. If one accepts such ascriptions, one can argue either (1) that future use must be added to the grounding base, or (2) that such cases show that meaning is not, ultimately, grounded in use. The following will defend the first option as the more promising of the two, though this ultimately requires understanding the relation between use and meaning as ‘normative’ in two important ways. The first (more familiar) way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between actual and correct use. The second sort of normativity is unique to theories that extend the grounding base into the future. In particular, if meaning is partially a function of future use, we can see our commitment to the ‘determinacy’ of meaning as a practical commitment that structures our linguistic practices rather than a theoretical commitment that merely describes them.
