McTaggart's Argument

In this paper, we articulate a version of non-standard A-theory – which we call Flow Fragmentalism – in relation to its take on the issue of supervenience of truth on being. According to the Truth Supervenes on Being (TSB) Principle, the truth of past- and future-tensed propositions supervenes, respectively, on past and future facts. Since the standard presentist denies the existence of past and future entities and facts concerning them that do not obtain in the present, she seems to lack (...) the resources to accept both past and future-tensed truths and the TSB Principle. Contrariwise, positions in philosophy of time that accept an eternalist ontology (e.g., B-theory, moving spotlight, and Fine’s and Lipman’s versions of fragmentalism) allow for a “direct” supervenience base for past- and future-tensed truths. We argue that Flow Fragmentalism constitutes a middle ground, which retains most of the advantages of both views, and allows us to articulate a novel account of the passage of time. (shrink)

Fine (2005, 2006) has presented a ‘trilemma’ concerning the tense-realist idea that reality is constituted by tensed facts. According to Fine, there are only three ways out of the trilemma, consisting in what he takes to be the three main families of tense-realism: ‘presentism’, ‘(external) relativism’, and ‘fragmentalism’. Importantly, although Fine characterises tense-realism as the thesis that reality is constituted (at least in part) by tensed facts, he explicitly claims that tense realists are not committed to their fundamental existence. Recently, (...) Correia and Rosenkranz (2011, 2012) have claimed that Fine’s tripartite map of tense realism is incomplete as it misses a fourth position they call ‘dynamic absolutism’. In this paper, I will argue that dynamic absolutists are committed to the irreducible existence of tensed facts and that, for this reason, they face a similar trilemma concerning the notion of fact-content. I will thus conclude that a generalised version of Fine’s trilemma, concerning both fact-constitution and fact-content, is indeed inescapable. (shrink)

Thisness Presentism outlines and defends a novel version of presentism, the view that only present entities exist and what is present really changes. Presentism is a view of time that captures a real and objective difference between what is past, present, and future, and which offers a model of reality that is dynamic and mutable, rather than static and immutable. The book advances a new defence of presentism by developing a novel ontology of thisness, combining insights about the nature of (...) essence, the metaphysics of propositions, and the relationship between true propositions and the elements of reality that make them true, alongside insights about time itself. It shows how, by accepting an ontology of thisness, presentists can respond to a number of pressing challenges to presentism, including claims that presentism cannot account for true propositions about the past, and that it is inconsistent with the reality of temporal passage and the openness of the future. This is one of the only book-length defences of presentism. It will be of interest to students and scholars working on the debate about presentism in the philosophy of time, as well as those interested in the metaphysics of propositions and truth-making, more generally.

Since J. McTaggart’s paper on “The Unreality of Time” the opposition of “A-theorists” and “B-theorists” establishes a focal point in the modern debate on the metaphysics of time: While “A-theorists” claim the existence of an objective present, moving along time positions, “B-theorists” maintain that time is just a set of ontologically equivalent coordinates, “now” being merely the indexical of the speaker’s position. Contemporary attempts to resolve the issue by resorting to the analysis of language or to the theory of science (...) seem to deliver no definite results. By contrast, practical and existential aspects of the two models promise to be more univocal guides in deciding between them. Particularly, C. D. Broad’s hybrid conception of a “growing block theory” attains special attractiveness in this regard. (shrink)

According to A-theories of time, the metaphysical ground of change and dynamicity is provided by a continuous shifting in which events are past, present and future (A-determinations). It is often claimed that these theories make better sense of our experience of dynamicity than their rival, the B-theories; according to the latter, dynamicity is grounded solely in the irreducible earlier-than relations (B-relations) which obtain between events or states of affairs. In this paper, I argue that the experience of time's dynamicity, on (...) the contrary, cannot be accounted for solely in terms of representations of irreducible A-determinations, because any representation which is adequate to ground these experiences must itself involve representation of irreducible B-relations, while it needs not involve representation of A-determinations. Even if, as a matter of contingent fact, our experiences of dynamicity consisted of representations of successions of A-determinations, what would account for them being experiences of dynamicity would be solely the B-theoretic relations of succession, rather than the irrelevant A-theoretic nature of the relata.

In this paper, I study one aspect of the philosophical encounter between Spinoza and Hegel: the question of the reality of time. The precise reconstruction of the debate will require a close examination of Spinoza's concept of tempus (time) and duratio (duration), and Hegel's understanding of these notions. Following a presentation of Hegel's perception of Spinoza as a modern Eleatic, who denies the reality of time, change and plurality, I turn, in the second part, to look closely at Spinoza's text (...) and show that Hegel was wrong in reading Spinoza as denying the reality of duration and change. Ironically, Hegel's misreading of Spinoza as denying the reality of duration and change has been compensated for by a reading of Hegel as denying the reality of time by one of Hegel's most prominent followers, John Ellis McTaggart. I discuss McTaggart's reading of Hegel's Logic in the final part of the paper. (shrink)

The thesis revolves around the following questions. What is time? Is time tensed or tenseless? Do things endure or perdure, i.e. do things persist by being wholly present at many times, or do they persist by having temporal parts? Do causes bring their effects into existence, or are they only correlated with each other? Within a realist approach to metaphysics, the author claims that the tensed view of time, the endurance view of persistence, and the production view of causality naturally (...) combine into what is called the dynamic view of temporal reality, and that the tenseless view of time, the perdurance view of persistence, and the correlation view of causality naturally combine into what is called the static view of temporal reality. The author argues in favour of a dynamic view. During the discussion a number of metaphysical problems are addressed. First, it is argued that the charges that the dynamic view is contradictory, made by J.M.E. McTaggart and David Lewis, are viciously circular. Secondly, it is argued that the static view cannot account for change, and deprives metaphysics of essential means to provide natural explanations to empirical phenomena. Thirdly, the author presents a novel account of the nature of necessary causal production. He suggests that the traditional conception of causes as essentially being external to the effects should be abandoned, and that causal production instead should be explicated in terms of reciprocal interactions between coexistent substances.

This essay is a critical introduction to the second part of the special issue Time and Reality. The volume contains responses to papers appeared in the first part, as well as many original articles. The aim of this introduction is to frame these works within the general arena of the philosophy of time, highlighting a number of recurrent themes. A central theme that emerges is a difficulty in pinning down the ontological structure underlying dynamicity and passage without postulating a primitive (...) notion of transiency that is conceptually independent of the instantiation of tense properties. I argue that this has far-reaching implications. (shrink)

In this paper I will present three arguments (based on the notions of constitution, metaphysical reality, and truth, respectively) with the aim of shedding some new light on the structure of Fine’s (2005, 2006) ‘McTaggartian’ arguments against the reality of tense. Along the way, I will also (i) draw a novel map of the main realist positions about tense, (ii) unearth a previously unnoticed but potentially interesting form of external relativism (which I will label ‘hyper-presentism’) and (iii) sketch a novel (...) interpretation of Fine’s fragmentalism (which I contrast with Lipman’s 2015, 2016b, forthcoming). (shrink)

McTaggart’s claim that time is unreal has caused a wave of consternation, but attention is rarely given to the initial context of that denial. This paper argues that McTaggart’s denial is motivated less by considerations of logic than by an ethical imperative, and in light of this, asks whether ethics is best served by denying time. I employ Kierkegaard’s distinction between pagan and Christian cognitions of time to suggest that McTaggart’s denial amounts to a neo-platonic/gnostic degradation of the temporal realm (...) which risks undermining the hope it seeks to cultivate. In place I offer an existential viewpoint. (shrink)

J.M.E. McTaggart first employed the now-standard distinction between the A- an B-series in an attempt to prove the unreality of time. I argue that McTaggart's analysis of time requires that a subject exist within the A-series, and as such lends itself to a Heideggerian conception of time, viewed both through Being and Time and Heidegger's interpretation of Aristotle's theory, that necessitates a 'personal' temporality in order to make 'world-time' intelligible. I also suggest that Heidegger's temporaility, formulated as a non-successive unity (...) grounded in Dasein's existential constitution as being-in-the-world, circumvents McTaggart's preemptive charge of circularity and therefore also avoids the conclusion that time is unreal.

Originally published in 1931, this book presents a concise biography of the British idealist metaphysician John McTaggart Ellis McTaggart. The text was largely written by the prominent political scientist Goldsworthy Lowes Dickinson, a close friend of the subject. Abundant material from McTaggart's memoirs, letters and other writings is included, with earlier chapters covering more personal areas and later ones focusing on his philosophical approach. Ilustrative figures and notes are also included. This book will be of value to anyone with an (...) interest in McTaggart, metaphysics and British idealism. (shrink)

A concept of the ‘actual now’ is introduced. The ‘actual now’ is negatively characterized by the fact that it is absent from the time-series. This does not mean that the ‘actual now’ is outside the time-series. For saying so would wrongly suggest the existence of an ‘outside’ where the ‘actual now’ could be located. Instead, one considers that the ‘actual now’ is just the name of ‘that with respect to which’ any event can be said to be past or future, (...) yet being no event by itself. It holds the same role with respect to time as Husserl’s transcendental ego with respect to the empirical self. McTaggart’s celebrated refutation of the reality of time is reinterpreted accordingly. To express this argument, one no longer needs to use the notions of ‘change’ or ‘time flow’, but only to point out the in-principle impossibility to refer to the ‘actual now’. (shrink)

No-futurists ('growing block theorists') hold that that the past and the present are real, but that the future is not. The present moment is therefore privileged: it is the last moment of time. Craig Bourne (2002) and David Braddon-Mitchell (2004) have argued that this position is unmotivated, since the privilege of presentness comes apart from the indexicality of 'this moment'. I respond that no-futurists should treat 'x is real-as-of y' as a nonsymmetric relation. Then different moments are real-as-of different times. (...) This reunites privilege with indexicality, but entails that no-futurists must believe in ineliminably tensed facts. (shrink)

The project of my dissertation was to advance the metaphysical debate about temporal passage, by relating it to debates about the perceptual experience of time and change. It seems true that we experience temporal passage, even if there is disagreement whether time actually passes, or what temporal passage consists in. This appears to give the defender of dynamic time an advantage in accounting for our experience. I challenge this by arguing that no major account of temporal perception can accommodate experiences (...) of temporal passage such that we could infer passage from them. This shows that static theories of time are at no disadvantage in accounting for the phenomenology of temporality. The conclusion has far reaching consequences: for instance, an important motivation for holding an A-theory of time is precisely the psychological intuition that we experience temporal passage. By undermining that intuition, I undermine the motivation for holding an A-theory. (shrink)

Seventh in the New Dialogues in Philosophy series, this book discusses the concept of time and shows in the simplest ways how time informs discussions about causality, creation, physics, natural disasters, and much more. Creating a series of conversations between two fictional characters, Bradley Dowden uses the characters to explore nine metaphysical issues involving time.

In light of the Special Theory of Relativity and the Minkowski creation of ‘spacetime’, the universe is taken to be a four-dimensional entity which postulates bodies as existing within a temporally extended reality. The Special Theory of Relativity’s implications liken the nature of the universe to a ‘block’ within which all events coexist equally in spacetime. Such a view strikes against the very essence of presentism, which holds that all that exists is the instantaneous state of objects in the present (...) moment. With respect to the present moment, events have a clear division into the past or future, however such regions do not exist in reality and the universe is a three-dimensional entity. The consequences of a four-dimensional universe are disturbing to say the least for our everyday human experience, with once objective facts about reality becoming dependent upon an observer’s relative motion and the debate over the extent of true free will in a Block Universe. This paper will look at arguments which seek to rescue the presentist view in light of Special Relativity so such four-dimensionalist implications do not have to be accepted. Two approaches will be considered. The first accepts that presentism is incompatible with Special Relativity, and seeks to show that the theory is ultimately false. The second holds that it is the Block Universe interpretation of Special Relativity that is wrong, and a version of presentism can be reconciled with Special Relativity. The paper will expound and critically examine both of these approaches to review whether the case for the three-dimensionalist and a fundamental passage of time can be made. (shrink)

Os presentistas nos dizem que os únicos objetos percorridos pelos quantificadoresde escopo mais amplo são aqueles que existem no presente, o que leva seus críticos aperguntarem o que torna verdadeiros os enunciados sobre o passado, como “Sócrates foi umfilósofo”. Em defesa do presentismo, e seguindo a proposta de Fiocco (2007), argumentamosque o que torna verdadeiro um enunciado sobre o passado é uma proposição, que proposiçõesnão existem no tempo, e que nada na teoria presentista compromete seus defensores com atese de que (...) o que não existe no tempo não existe.

Tallant (2007) has challenged my recent defence of no-futurism (Button 2006), but he does not discuss the key to that defence: that no-futurism's primitive relation 'x is real-as-of y' is not symmetric. I therefore answer Tallant's challenge in the same way as I originally defended no-futurism. I also clarify no-futurism by rejecting a common mis-characterisation of the growing-block theorist. By supplying a semantics for no-futurists, I demonstrate that no-futurism faces no sceptical challenges. I conclude by considering the problem of how (...) to interpret the relation 'x is real-as-of y'. -/- (NB: A correction to this article appears in Analysis 68.1.). (shrink)

What does the passage of time consist in? There are some suggestive metaphors. âEvents approach us, pass us, and recede from us, like sticks and leaves floating on the river of time.â âWe are moving from the past into the future, like ships sailing into an unknown ocean.â There is surely something right and deep about these metaphors. But how close are they to the literal truth? In this book Bradford Skow argues that they are far from the literal truth. (...) Skowâs argument takes the form of a defense of the block universe theory of time, a theory that, in many ways, treats time as a dimension of reality that closely resembles the three dimensions of space. Opposed to the block universe theory of time are theories that take the metaphors more seriously: presentism, the moving spotlight theory, the growing block theory, and the branching time theory. These are theories of ârobustâ passage of time, or âobjective becoming.â Skow argues that the best of these theories, the block universe theoryâs most worthy opponent, is the moving spotlight theory, the theory that says that âpresentnessâ moves along the series of times from the past into the future. Skow defends the moving spotlight theory against the objection that it is inconsistent, and the objection that it cannot answer the question of how fast time passes. He also defends it against the objection that it is incompatible with Einsteinâs theory of relativity. Skow proposes several ways in which the moving spotlight theory may be made compatible with the theory of relativity. Still, this book is ultimately a defense of the block universe theory, not of the moving spotlight theory. Skow holds that the best arguments against the block universe theory, and for the moving spotlight theory, start from the idea that, somehow, the passage of time is given to us in experience. Skow discusses several different arguments that start from this idea, and argues that they all fail. (shrink)

McTaggart’s argument for the unreality of time, first published in 1908, set the agenda for 20th-century philosophy of time. Yet there is very little agreement on what it actually says—nobody agrees with the conclusion, but still everybody finds something important in it. This book presents the first critical overview of the last century of debate on what is popularly called "McTaggart’s Paradox". Scholars have long assumed that McTaggart’s argument stands alone and does not rely on any contentious ontological principles. The (...) author demonstrates that these assumptions are incorrect—McTaggart himself explicitly claimed his argument to be dependent on the ontological principles that form the basis of his idealist metaphysics. The result is that scholars have proceeded to understand the argument on the basis of their own metaphysical assumptions, duly arriving at very different interpretations. This book offers an alternative reading of McTaggart’s argument, and at the same time explains why other commentators arrive at their mutually incompatible interpretations. It will be of interest to students and scholars with an interest in the philosophy of time and other areas of contemporary metaphysics. (shrink)

Ross Cameron’s the moving spotlight reminds me a bit of Pirates of the Caribbean. Although there are no pirates, it’s a rip roaring swashbuckling adventure. It’s a wild ride. Truth be told, many of us will probably conclude that it’s no more plausible an account of our world than is Pirates of the Caribbean a faithful depiction of piracy. I’m not a moving spotlight theorist. There aren’t many of them out there. I’m not even an A-theorist, though there are plenty (...) of those. And there was little chance that this book would convert me. But for all that it’s well worth the read; because even if you come away from the book holding onto the same view of time as you had going in, you will certainly learn something along the way.

I discuss the general form of arguments that profess to prove that the view that things endure in tensed time through causally produced change (the dynamic view) must be false because it involves contradictions. I argue that these arguments implicitly presuppose what has been called the temporal parity thesis, i.e. that all moments of time are equally existent and real, and that this thesis must be understood as the denial of the dynamic view. When this implicit premise is made explicit, (...) the arguments turn out to be either circular, they presuppose what they profess to prove, or mere demonstrations of the fact that the dynamic view is incompatible with its own negation. Furthermore, I discuss the metaphysical consequences of accepting the temporal parity thesis, arguing that it deprives us of the means to provide natural explanations to empirical phenomena.

I sitt berömda bevis för tidens overklighet påstod McTaggart att det sätt händelser tycks skifta position i tiden från framtid till nutid och till förfluten tid, innebär en motsägelse. Vad McTaggart egentligen menade har varit föremål för en livlig debatt ända sedan beviset först publicerades 1908. Beviset består av två delar. I den första argumenterar McTaggart för att ingenting kan förändras förutom genom att övergå från framtid till förfluten tid. I den andra argumenterar han för att en sådan övergång innebär (...) en motsägelse och att det därför inte kan finnas någon förändring överhuvudtaget, vilket i sin tur innebär att det heller inte finns någon tid. De flesta filosofer är i dag eniga om att McTaggart har fel, men oeniga om på vilket sätt han har fel. Olika filosofer förkastar olika delar av beviset, beroende på om de har vad som kallas en A- eller B-uppfattning av tiden. De som har en A-uppfattning förnekar att tid förstådd som övergång från framtid till förfluten tid är motsägelsefull. De som har en B-uppfattning förnekar att en övergång från framtid till förfluten tid är nödvändig för förändring, men håller med om att sådan övergång är motsägelsefull. Det är min uppfattning att denna oenighet beror på att McTaggarts argument från första början blivit missuppfattat, av både A- och B-teoretiker. Av någon anledning har det alltid betraktats som ett självständigt argument, ett som är oberoende av det ontologiska system McTaggart förespråkade. Jag föreslår ett nytt sätt att förstå hur han menade att tiden är motsägelsefull. Ett sätt som tar hans ontologiska system som utgångspunkt. (shrink)

Ross P. Cameron argues that the flow of time is a genuine feature of reality. He suggests that the best version of the A-Theory is a version of the Moving Spotlight view, according to which past and future beings are real, but there is nonetheless an objectively privileged present. Cameron argues that the Moving Spotlight theory should be viewed as having more in common with Presentism than with the B-Theory. Furthermore, it provides the best account of truthmakers for claims about (...) what was or will be the case. Cameron goes on to defend an account of the open future, and argues that this is a better account than that available to the Growing Block theory. (shrink)

To prove the equivalence one must start with one side, and the earlier-later side seems, for starting with, logically the clearer. The equivalence is provable on reasonable definitions of ‘past’, ‘present’ and ‘future’ in terms of the earlier-later structure of time. McTaggart's attempted distinction between the past-present-future A series and the earlier-later B series, as though they were rivals for the structure of time, is based on an unexamined, and false, assumption. The equivalence shows they are not rivals; they are (...) quite consistent with each other. A very serious consequence is that all subsequent argument, from the A side or the B, however sophisticated, is flawed to the extent that it accepts McTaggart's false distinction. (shrink)

This paper concerns the issue of time understood as the dimension of change. I want to discuss it in relation to the argument which had a considerable impact on modern philosophical and physical researches in the field: Mc Taggart‟s „argument of unreality of time‟. I will begin by briefly outlining such argument and then I will examine some of the major objections to it. I question if this kind of description does embody the reality of time. I will conclude by (...) pointing out certain difficulties related to the explanation of temporal change in virtue of spatial representations. (shrink)

My topic is the question 'Does time pass?'. Although much has been written in attempts to answer this question, not enough attention has been paid to the asking of the question itself. As a result, it has not been clear exactly what is at issue in this matter, and, consequently, it has not been clear just what are the different views available to one who wishes to give an answer to the question. I hope to ameliorate this situation. ;The aims (...) of my essay are: to state the issues involved in the controversy over temporal passage in a fruitful way; to formulate what I see as the leading candidates among the possible responses to those issues; and to consider the best arguments relevant to the choice among these alternative views. ;Roughly one-quarter of the essay is devoted to linguistic questions about time and tense. Another quarter is devoted to metaphysical matters involving the status of such putative properties as pastness, presentness and futurity. What emerge are not just two but, rather, five distinct views about whether or not time passes: one view, which I call the 4D view, to the effect that time does not pass, and four different views, which I call the 3D views, to the effect that time does pass. Each of these five views consists of a package of linguistic and metaphysical components. ;Once I have formulated these five different views, I present, for each of the five views, a formal language, with semantics, that would be appropriate for that view. Next, various arguments that have been suggested in the literature against the claim that time passes are considered as arguments against the 3D views; each such argument is found to be defective. Similarly, various arguments that have been suggested in the literature against the claim that time does not pass are considered as arguments against the 4D view; each of these arguments is also found to be defective. ;Finally, I explain why I prefer a certain one of the 3D views over its four rivals, and I consider some possible objections to that view.

To be truly provocative and outrageous the superior philosophical sophistry will commonly possess four somewhat adventitious features. I shall rate it as classic if it has all four. First, and least adventitiously, the argument will be crisp and initially seductive. Second, by the standard the sophistry sets direct rebuttal will be laborious and diffuse. Third, the recipe for the latter will prescribe that we pick out some hitherto unarticulated logical principle such that if the principle be true then the sophistical (...) argument must be invalid, and then, on the strength of that consequence assume the principle to be true. Consequently and fourth, as an antidote parody is supreme. With a persuasive absence of fuss and bias we can turn the tables if we show that, if the sophistical argument were really valid, then some structurally similar argument would prove just as consummately far too much. In short, from the rhetorical point of view at least, Gaunilo is more lethal than Kant. Even if the similarity is defective, the sophist will lose some of his adventitious and insufferable poise, if he ventures to show why. (shrink)
