Temporal externalism and dispositionalist metametasemantics

According to temporal externalism, the meaning and reference of at least some of our terms depend on facts about the future. Temporal externalists claim that their view provides the best explanation of our linguistic practices. This paper will argue that, assuming a metametasemantic dispositionalist view, the linguistic practices temporal externalists appeal to can be accounted for without appealing to temporal externalism, insofar as these linguistic practices correspond to our use of terms. Temporal externalism is therefore not obviously the best explanation of our linguistic practices. Additionally, this paper will argue against recent claims to the effect that a metametasemantic dispositionalist view motivates a form of temporal externalism.
