Craig Callender’s What Makes Time Special? (OUP 2017) advocates and practices an innovative, thoroughly interdisciplinary approach to philosophical questions about time and temporal features of our lives. Grappling with it is of intrinsic philosophical interest; it is also part of responding to the methodological invitation the book issues to philosophers of time. This paper is motivated by the wish to clarify WMTS’s philosophical underpinnings. The main claim of the paper is that WMTS relies on an ambiguity between rejecting the A-theory versus B-theory debate, and endorsing a position within that debate. This ambiguity leads to a somewhat unstable position on how a key feature of manifest time, namely our sense of time as flowing, arises from physical time. The paper ends with a suggestion for how to resolve the ambiguity, in a way that is in line with the gist of Callender’s overall vision for the field.

What is the relation between metaphysical and psychological insights into temporal asymmetries? This chapter examines that question on the basis of a case study concerning the temporal Doppler effect (Caruso, Van Boven, Chin, & Ward, 2013). Caruso et al. propose that future events seem closer than past ones at an equal objective temporal distance because we experience subjective movement through time. I explore ways of interpreting their discussion in the light of the metaphysical debate between A- and B-theorists over whether time really passes and whether the future is genuinely ‘open’ while the past is ‘fixed’. I argue for the following claims: (1) Caruso et al.’s talk of a subjective movement through time seems best interpreted as concerning our longer term cognitive relationship to time; (2) both A- and B-theoretic interpretations of their discussion are viable as interpretations; (3) if combined with Priorean arguments for the A-theory, it takes some work to make sure the A-theoretic interpretation respects Van Boven and Caruso’s constraint that the objective temporal distance cannot directly influence psychological outcomes without influencing psychological intermediaries; and (4) a third, less metaphysically loaded interpretation may be preferable to both the A- and the B-theoretic ones.
