The future ain’t what it used to be

Abstract

AbstractThis paper explores mutable futurism, the view according to which the future can literally change—that is, it can happen that a future time t changes from containing an event E to lacking it (or vice versa). Mutable futurism has received little attention so far, and the details and implications of the view are underexplored in the literature. For instance, it currently lacks a precise metaphysical model and a formal semantics. Although we do not endorse mutable futurism, our goal here is to strengthen the case for mutable futurism and help establish it as a worthy contender in the debate on the philosophy of time. To attain this goal, (i) we try to make mutable futurism, along with its metaphysical and inferential commitments, as clear as possible, by providing it with a coherent metaphysical model and a plausible semantics, and (ii) we show that it can be backed by theoretical reasons.
