The theorist who denies the objective reality of non-relational temporal properties, or ‘A-series’ determinations, must explain our experience of the passage of time. D.H. Mellor, a prominent denier of the objective reality of temporal passage, draws, in part, on Kant in offering a theory according to which the experience of temporal passage is the result of the projection of change in belief. But Mellor has missed some important points Kant has to make about time-awareness. It turns out that Kant's theory of time-awareness also involves projection – but for him, the projection of temporal passage is necessary to any coherent experience at all, and for this reason events in the world cannot be represented except as exhibiting real tensed change. Consequently we cannot intelligibly suppose the world we know to be without the passage of time. This fact would permit a modest transcendental argument the conclusion of which is that we are entitled to describe the world in terms of temporal passage.
