This paper discusses the problem of inconsistencies in the metaphorical conceptualizations of time that involve motion within the framework of conceptual metaphor theory (CMT). It demonstrates that the TIME AS A PURSUER metaphor contrasts with the reverse variant TIME AS AN OBJECT OF PURSUIT, just as the MOVING TIME metaphor contrasts with the MOVING OBSERVER variant. Such metaphorical conceptualizations of time functioning as pairs of minimally differing variants based on Figure-Ground reversal are, strictly speaking, inconsistent with one another. Looking at (...) these inconsistencies from a wider perspective suggests that time may belong to a separate category of conceptual phenomena. This paper puts forward a proposal to approach time from the perspective of “phenomena of the third kind”, which according to Keller’s thesis include conceptual establishments resulting from human cognition, but not of human design.

According to the No Alternate Possibilities argument, if time passes then the rate at which it passes could be different but time cannot pass at different rates, and hence time cannot pass. Typically, defenders of the NAP argument have focussed on defending premise, and have taken the truth of for granted: they accept the orthodox view of rate necessitarianism. In this paper we argue that the defender of the NAP argument needs to turn her attention to. We describe a series (...) of worlds that appear to contain differential passage: worlds where time passes at different rates in different subregions. If the NAP argument is to succeed, rate necessitarians must show that each of these worlds is either metaphysically impossible, or does not contain differential passage. (shrink)

I examine here if Kant can explain our knowledge of duration by showing that time has metric structure. To do so, I spell out two possible solutions: time’s metric could be intrinsic or extrinsic. I argue that Kant’s resources are too weak to secure an intrinsic, transcendentally-based temporal metrics; but he can supply an extrinsic metric, based in a metaphysical fact about matter. I conclude that Transcendental Idealism is incomplete: it cannot account for the durative aspects of experience—or it can (...) do so only with help from a non-trivial metaphysics of material substance.

According to the growing block ontology of time, there (tenselessly and unrestrictedly) exist past and present objects and events, but no future objects or events. The growing block is made attractive not just because of the attractiveness of its ontological basis for past-tensed truths, the past’s fixity, and future’s openness, but by underlying principles about the right way to fill in this sort of ontology. I shall argue that given these underlying views about the connection between truth and ontology, growing (...) blockers incur an ontological commitment to an infinite number of temporal dimensions (“hypertime”). This commitment to hypertime generates a vicious explanatory regress. It also undermines the idea that the reality of the past is sufficient to explain why truths about the past are fixed. Both of these implications are highly unattractive; growing blockers would do well to clarify what other motivations they can offer for their view and how they can avoid these consequences. (shrink)

I offer a novel account of temporal passage. According to this account, time passes in virtue of there being events in progress. I argue that such an account of temporal passage can explain the direction and whoosh of temporal passage. I also consider two prominent accounts of temporal passage and argue that they amount to special versions of the thesis that time passes in virtue of there being events in progress.

Even hard-core metaphysicians should admit that certain disputesmay indeed turn out not tobe substantive. The debate between presentism and eternalism has recently come undersceptical attack. The aim of the paper is to argue that a certain approach to presentism is indeedin danger of succumbing to the sceptic, and thus a no-go for the presentist.

Recent work on time. There is, at present, a lot of varied and interesting work being done in the philosophy of time; too much for me to fully engage with all of it here. I will focus on three debates that have been particularly busy over the last few years: how do presentists ground true propositions about the past? How does time pass? How do we experience time’s passing?

A-theorists and B-theorists debate whether the "Now" is metaphysically distinguished from other time slices. Analogously, one may ask whether the "I" is metaphysically distinguished from other perspectives. Few philosophers would answer the second question in the affirmative. An exception is Caspar Hare, who has devoted two papers and a book to arguing for such a positive answer. In this paper, I argue that those who answer the first question in the affirmative---A-theorists---should also answer the second question in the affirmative. This (...) is because key arguments in favor of the A-theory are more effective asarguments in favor of the resulting combined position, and key arguments against the A-theory are ineffective against the combined position.

According to the No Alternate Possibilities argument, if time passes then the rate at which it passes could be different. Thus, time cannot pass, since if time passes, then necessarily it passes at a rate of 1 second per second. One response to this argument is to posit hypertime, and to argue that at different worlds, time passes at different rates when measured against hypertime. Since many A-theorists think we can make sense of temporal passage without positing hypertime, we pursue (...) a different response. We describe several worlds that do not contain hypertime, but do contain differential passage: worlds where time passes at different rates in different subregions within the same world. Hence we argue that even if we focus just on the set of worlds that do not contain hypertime (whether this is all, or only some of the worlds) we find that not all these worlds are such that time passes at a rate of 1 second per second. Thus the No Alternate Possibilities argument fails even when restricted to just this set of worlds. (shrink)

In metaphysics, there are a number of distinct but related questions about the existence of “further facts”—facts that are contingent relative to the physical structure of the universe. These include further facts about qualia, personal identity, and time. In this article I provide a sequence of examples involving computer simulations, ranging from one in which the protagonist can clearly conclude such further facts exist to one that describes our own condition. This raises the question of where along the sequence the (...) protagonist stops being able to soundly conclude that further facts exist. (shrink)

There is a lingering objection to the idea of the passage of time. Roughly speaking, the argument runs as follows: if time passes, its passage must occur at some rate, but there is no such rate; hence, the passage of time is a myth. While some philosophers try to reject premise, I wish to challenge the first premise by arguing that time may pass with or without a rate. My argument addresses two cases, one that identifies the passage of time (...) with changes in things and one that does not. I call the former view ‘the Priorian passage theory’, and the latter view ‘the pure passage theory’. I argue that each dynamic view of time is immune to the rate argument. Further, I suggest a possible extension of the Priorian passage theory, in which the passage of time is identified with the pure persistence of things. (shrink)

Some philosophers believe that the passage of time is a real phenomenon. And some of them find a reason to believe this when they attend to features of their conscious experience. In fact this “argument from experience” is supposed to be one of the main arguments for passage. What exactly does this argument look like? Is it any good?

One of the more serious criticisms of the B-theory is that by denying the passage of time or maintaining that passage is a mind-dependent illusion or appearance, the B-theory gives rise to a static, block universe and thereby removes what is most distinctively timelike about time. The aim of this paper is to discuss the R-theory of time, after Russell, who Richard Gale calls “the father of the B-theory,” and explain how the R-theory can respond to the criticisms just raised, (...) and others. In the course of my discussion I shall clarify differences between versions of the A-, B- and R-theories of time, and argue that McTaggart’s conception of the B-series and more specifically, the B-relations that generate it, has been instrumental in misconstruing the A-/B-theory debate resulting in criticisms of the B-theory that can be seen to be fallacious when applied to the R-theory.

There are long-standing questions about the Big Bang: What were its properties? Was there nothing before it? Was the universe always here? Many conceptual issues revolve around time. This paper gives a novel model based on McTaggart’s temporal distinction between the A-series (future-present-past) and B-series (earlier-times to later-times). These series are useful while situated in a Presentist and Fragmentalist account of quantum mechanics, one in which the consistency with the Special Relativity (in particular the relativity of simultaneity) will be made (...) explicit (section 6). This allows us to make a fruitful distinction between two pertinent questions: what happens as we go to earlier times toward the Big Bang? And: what happens as we go further into the past toward the Big Bang? (shrink)

Possibilism—the view that there are non-actual, merely possible entities—is a surprisingly resilient doctrine.1 One particularly hardy strand of possibilism—the modal realism championed by David Lewis—continues to attract both foes who seek to demonstrate its falsity (or at least stare its advocates into apostasy) and friends who hope to defend modal realism (or, when necessary, modify modal realism so as to avoid problematic objections).2 Although I am neither a foe nor friend of modal realism (but some of my best friends are!), (...) like many I continue to be fascinated by the doctrine.

Presentists argue that only the present is real. In this paper, I ask what duration the present has on a presentist’s account. While several answers are available, each of them requires the adoption of a measure and, with that adoption, additional work must be done to define the present. Whether presentists conclude that a reductionist account of duration is acceptable, that duration is not an applicable concept for their notion of the present, that the present has a duration of zero, (...) or that that the present has a duration, a more robust account of the present is required. I suggest that some of the most difficult questions about duration can be avoided at the cost of no longer viewing presentism as a theory about time, but rather as a theory about existence. In the conclusion, I suggest an interpretation of presentism that allows it to endorse the view that time is nothing more than the measure of change. (shrink)

Time appears to us to pass. Some philosophers think that we should account for these experiences by appeal to change in what there unrestrictedly is . I argue that such an appeal can only be the beginning of an account of passage. To show this, I consider a minimal type of view—a purely topological view—that attempts to account for experiences as of passage by an appeal to ontological change and topological features of the present. I argue that, if ontological change (...) is needed to account for our experiences as of passage, then there are other features of our experiences as of passage that a purely topological view does not have the resources to explain. These features include the implacability of time’s passage, the orderliness of time’s passage, and the impossibility of a having a past that was never present. (shrink)

Detractors of temporal passage often argue that it is meaningless to say that time passes or flows, else time would have to pass at a rate of one second per second, which is in fact not a rate but a number, namely one. Several attempts have been recently made to avoid this conclusion, by retorting that one second per second is in fact not identical to one. This paper shows that this kind of reply is not satisfactory, because it demands (...) a substantive revision of the algebraic behaviour of quantities. (shrink)
