Sam Cumming, Paolo Santorio, and Dilip Ninan have argued that proper names and pronouns, including the first-person pronoun 'I', should be treated semantically as variables. This treatment allows us to see them both as directly referential (in agreement with Kaplanian orthodoxy) and as potentially shifting their reference in modal and doxastic contexts (against Kaplanian orthodoxy). I will make the case that if the arguments for variabilism are any good, they generalize to all semantic categories, and therefore support panvariabilism, the view that all lexical items should be treated as variables. I will then offer an independent motivation for panvariabilism: it is needed to solve an analogue of the problem of felicitous underspecification that arises, not for the contextual supplementations of lexical items, but for the lexical items themselves.  Panvariabilism is the semantics we need to fit the expressivist pragmatics I argued for in my Woodbridge Lectures (Journal of Philosophy 117, 2020).
