It has been argued recently that one major difficulty facing the A-theory of time consists in the view’s failure to provide a satisfactory account of the passage of time. Critics have objected that this particular charge is premised on an unduly strong conception of temporal passage, and that the argument does not go through on alternative, less demanding conceptions of passage. The resulting dialectical stalemate threatens to prove intractable, given the notorious elusiveness of the notion of temporal passage. (...) Here I argue that there is progress to be made in this regard. The argument from passage takes issue with a certain feature of the standard versions of the A-theory that is in fact problematic independently of worries about temporal passage. To illustrate this, I present a new argument, the argument from comprehensiveness, which demonstrates that the standard A-theoretic account of temporal reality is inadequate, even if it is granted that it can accommodate passage.

The A-theory of time says that it is an objective, non-perspectival fact about the world that some events are present, while others were present or will be present. I shall argue that the A-theory has some implausible consequences for inductive reasoning. In particular, the presentist version of the A-theory, which holds that the difference between the present and the non-present consists in the present events being the only ones that exist, is very much in trouble.

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.

The paper has two parts: First, I describe a relatively popular thesis in the philosophy of propositional attitudes, worthy of the name ‘taking tense seriously’; and I distinguish it from a family of views in the metaphysics of time, namely, the A-theories (or what are sometimes called ‘tensed theories of time’). Once the distinction is in focus, a skeptical worry arises. Some A-theorists maintain that the difference between past, present, and future, is to be drawn in (...) terms of what exists: growing-block theorists eschew ontological commitment to future entities; presentists, to future and past entities. Others think of themselves as A-theorists but exclude no past or future things from their ontology. The metaphysical skeptic suspects that their attempt to articulate an ‘eternalist’ version of the A-theory collapses into merely ‘taking tense seriously’– a thesis that does not imply the A-theory. The second half of the paper is the search for a stable eternalist A-theory. It includes discussion of temporary intrinsics, temporal parts, and truth. (shrink)

The New A-theory of Time is the view, to be elaborated and defended in this article, that many times exist, and that time is real in virtue of every moment in time bearing each of the so-called A-properties: past, present and future. I argue that TNAT is at least as theoretically virtuous as mainstream views in the philosophy of time and may have some claim to being our best theory of time. I show that the (...) properties ‘past’, ‘present’ and ‘future’ can be understood as compatible intrinsic properties. Having demonstrated that this account of the A-properties is coherent, I go on to demonstrate how TNAT can give us an account of passage, change and the truth-conditions for temporal sentences. In the final section of the article, I develop a tentative argument in favour of TNAT, though concede that we have to settle for the result that TNAT is on a par with our other theories of time. In the remainder of this opening section, my aim is to situate the current proposal as a direct response to Mc.. (shrink)

This paper proposes a view of time that takes passage to be the most basic temporal notion, instead of the usual A-theoretic and B-theoretic notions, and explores how we should think of a world that exhibits such a genuine temporal passage. It will be argued that an objective passage of time can only be made sense of from an atemporal point of view and only when it is able to constitute a genuine change of objects across time. (...) This requires that passage can flip one fact into a contrary fact, even though neither side of the temporal passage is privileged over the other. We can make sense of this if the world is inherently perspectival. Such an inherently perspectival world is characterized by fragmentalism, a view that has been introduced by Fine in his ‘Tense and Reality’ (2005). Unlike Fine's tense-theoretic fragmentalism though, the proposed view will be a fragmentalist view based in a primitive notion of passage. (shrink)

Professor Schiller's question, “Must philosophers disagree?” can be answered in the negative if a technique can be worked out whereby it becomes possible to answer the question, “What are they talking about?” It is the aim of the ensuing remarks to provide at least the outline of such a technique and to illustrate its possible effectiveness in the specific context of controversies about the nature of time. That philosophers may continue to disagree in spite of the suggestions offered is, (...) of course, to be expected in view of the long history of failures which compromise positions have encountered. The fate of the conciliator usually has been to receive the contempt of the embattled polemicists, and the fate of his peacemaking, to be construed as just another theory. Of course, this is in most cases the ulterior motive for his pretended altruism in assuming the rôle of arbitrator. Yet there are theories and theories. A position like that of Hume on the question of causality may reasonably be opposed to that of Leibniz but not in the same sense as to that of Kant. For the latter does attempt to provide a bridge between rationalism and empiricism and to do justice to the valid claims of each. The theory of time here proposed immodestly attempts a rapprochement among the multitudinous doctrines of time by setting forth one more doctrine. (shrink)

[full article, abstract in English; only abstract in Lithuanian] Walton’s thesis of transparency of photographs has spurred much dispute among critics. One of the popular objections is spatial agnosticism, an argument that concerns the inertia of egocentric spatial information vis-a-vis a photograph. In this paper, I argue that spatial agnosticism fails. Spatial agnostics claim, for a wrong reason, that a photographic image cannot carry egocentric spatial information. I argue that it is the disjuncture of the photographic world in which the (...) depicted object situated from the space in which the viewer of the photograph resides that renders the photograph spatially agnostic. It is the timeless photographic world rather than the photographic object that renders egocentric spatial information inert. With this new formulation of spatial agnosticism, I propose that spatial agnosticism needs to be coupled with the temporal dimension in the efforts to refute the thesis of transparency of photographs.

In this book and the companion volume The Tenseless Theory of Time: A Critical Examination, Craig undertakes the first thorough appraisal of the arguments for and against the tensed and tenseless theories of time.

This thesis introduces and defends a ‘C theory’ of time. The metaphysics of time literature is primarily concerned with the distinction between the A and B theories of time, with the disagreement concerning whether the passage of time is an objective feature of reality. I argue that the distinction between the B and C theories—in terms of whether time has a ‘privileged’ direction—is of more obvious relevance to the philosophy of physics than is (...) the distinction between the A and B theories. The thesis has three main contentions. (1) In order to maintain a substantial metaphysical dispute between the different theories of time, they must be defined in terms of structural properties, and the naturalistic metaphysics of time direction involves the assessment of these structures in light of contemporary physics. (2) The A theory of time requires a model with two temporal dimensions, and although such a model provides a resolution to a number of problems faced by standard A theories, it is not motivated by physical theory. (3) The dispute between the B and C theories of time is of direct relevance to the philosophy of physics: the B theorist’s assumption of the existence of a privileged temporal direction is of explanatory relevance to physics; and a comparison between unidirectional and adirectional explanations in physics can in principle shed light on whether time is B- or C-theoretic.

: I offer a new approach to the increasingly convoluted debate between the A- and B-theories of time, the ‘tensed’ and ‘tenseless’ theories. It is often assumed that the B-theory faces more difficulties than the A-theory in explaining the apparently tensed features of temporal experience. I argue that the A-theory cannot explain these features at all, because on any physicalist or supervenience theory of the mind, in which the nature of experience is fixed by the physical state (...) of the world, the tensed properties of time posited by the A-theory could play no role in shaping temporal experience. It follows that the A-theory is false; even a priori arguments for it fail, because they still require the tensed vocabulary which is used to describe temporal experience. (shrink)

permits a sound and rigorously definable notion of ‘originating cause’ or causa causans—a type of transition event—of an outcome event. Mackie has famously suggested that causes form a family of ‘inus’ conditions, where an inus condition is ‘an insufficient but non-redundant part of an unnecessary but sufficient condition’. In this essay the needed concepts of BST theory are developed in detail, and it is then proved that the causae causantes of a given outcome event have exactly the structure of a (...) set of Mackie inus conditions. The proof requires the assumption that there is no EPR-like ‘funny business’. This seems enough to constitute a theory of ‘causation’ in at least one of its many senses.

After precisely specifying the thesis of the causal theory of time, Grünbaum's program developed to support this thesis is examined. Four objections to his definition of temporal order in terms of a more primitive causal relation are put and held to be conclusive. Finally, the philosophical arguments that Grünbaum has proposed supporting the desirability of establishing a causal theory of time are shown to be either invalid or inconclusive.

This paper proposes a view of time that takes passage to be the most basic temporal notion, instead of the usual A-theoretic and B-theoretic notions, and explores how we should think of a world that exhibits such a genuine temporal passage. It will be argued that an objective passage of time can only be made sense of from an atemporal point of view and only when it is able to constitute a genuine change of objects across time. (...) This requires that passage can flip one fact into a contrary fact, even though neither side of the temporal passage is privileged over the other. We can make sense of this if the world is inherently perspectival. Such an inherently perspectival world is characterized by fragmentalism, a view that has been introduced by Fine in his ‘Tense and Reality’ (2005). Unlike Fine's tense-theoretic fragmentalism though, the proposed view will be a fragmentalist view based in a primitive notion of passage. (shrink)

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)

An important aspect of the debate between the A-theory and the B-theory of time relates to the supposed implications of each for some of the most basic human attitudes and stances. The asymmetry in our attitudes towards past and future events in our life (pleasant and unpleasant), and towards the temporal limits of our existence, that is, toward birth and death, is supposedly considered differently by the two theories. I argue that our attitudes are neither justified nor discredited (...) by anything which is in debate between the A-Theory and the B-theory, and therefore that neither theory of time is supported by the asymmetry in our attitudes.

“The universe is expanding, not contracting.” Many statements of this form appear unambiguously true; after all, the discovery of the universe’s expansion is one of the great triumphs of empirical science. However, the statement is time-directed: the universe expands towards what we call the future; it contracts towards the past. If we deny that time has a direction, should we also deny that the universe is really expanding? This article draws together and discusses what I call ‘C-theories’ (...) of time — in short, philosophical positions that hold time lacks a direction — from different areas of the literature. I set out the various motivations, aims, and problems for C-theories, and outline different versions of antirealism about the direction of time. (shrink)

This paper introduces a new theory in temporal ontology, ‘wave theory’, and argues for its attractions over and above existing tensed theories of time.

Timing adjustment is an important ability for living organisms. Wild animals need to act at the right moment to catch prey or escape a predator. Land plants, although limited in their movement, need to decide the right time to grow and bloom. Humans also need to decide the right moment for social actions. Although scientists can pinpoint the timing of such behaviors by observation, we know extremely little about how living organisms as actors or players decide when to act (...) – such as the exact moment to dash or pounce. The time measurements of an outsider-observer and the insider-participants are utterly different. We explain how such essential operations of timing adjustment and temporal spanning, both of which constitute a single regulated set, can be carried out among organisms. For this purpose, we have to reexamine the ordinary conception of time. Our specific explanatory tools include the natural movement known as the upbeat (anacrusis) in music, a rhythmic push for the downbeat that follows, which predicts future moves as an anticipatory lead-in. The scheme is situated in and is the extension of our formulation of E-series time, i.e., timing co-adjusted through interaction, which is derived from the semiotic/communicative perspectives. We thereby demonstrate that a prediction-based timing system is not mechanical but communicative and entails meanings for future anticipation. (shrink)

Whistleblowing” has entered the scholarly and the public debate as a way of describing the exposure by the member of an organization of episodes of corruption, fraud, or general abuses of power within the organization. We offer a critical survey of the main normative theories of whistleblowing in the current debate in political philosophy, with the illustrative aid of one of the epitomic figures of a whistleblower of our time: Edward Snowden. After conceptually separating whistleblowing from other forms (...) of wrongdoing disclosures, we introduce and discuss two families of normative views of this practice: the “Extrema Ratio” and the “Deontic” views. We show how the two views can be usefully considered in tandem to offer an all-round assessment of the moral justification of whistleblowing either as an extraordinary individual conscientious act of indictment or as an ordinary dutiful organizational practice of answerability that enables the capacity of self-correction of an organization.

The paper proposes a re-assessment of Reichenbach’s ‘causal’ theory of time. Reichenbach’s version of the theory, first proposed in 1921, is interesting because it is one of the first attempts to construct a causal theory as a relational theory of time, which fully takes the results of the Special theory of relativity into account. The theory derives its name from the cone structure of Minkowski space–time, in particular the emission of light signals. At first Reichenbach defines an (...) ‘order’ of time, a ‘before-after’ relationship between mechanical events. In his later work, he comes to the conclusion that the ‘order’ of time needs to be distinguished from the ‘direction’ of time. He therefore abandons the sole focus on light geometry and turns to Boltzmann’s statistical version of thermodynamics. However, as Einstein pointed out, the emission and reception of light signals have thermodynamic aspects. When this is taken into account, Reichenbach’s ‘causal’ theory turns out to be an entropic theory of time. It also emerges that Reichenbach discusses phase space and typicality arguments in support of his dynamic view of time. They provide a better understanding of the notion of entropy. This unifies his approach and helps to answer some of the standard objections against a causal theory of time. (shrink)

There is an eminent tradition of thought that sees in the phenomenon of time something contradictory. This tradition has been recently revived by some contemporary proponents of dialethism – the view that there are true contradictions. In this paper, I will contribute to this line of thinking by tracing the first steps of a dialethic account of time-consciousness. In particular, I will argue that the experiential flow of time can be accounted for in the framework of an (...) intentionalist approach to temporal perception if we conceive of time-consciousness as a quasi-multiplicity, i.e., a multiplicity of non-self-identical parts, hence the embrace of dialethism. Section 1 introduces dialethism, discusses Priest's dialethic theory of motion and time, and motivates the project of a dialethic account of time-consciousness. Section 2 introduces the intentionalist approach to time-consciousness and distinguishes pure intentionalism from sense-data intentionalism; both subscribes to a certain Principle of Simultaneous Awareness but interprets it differently. In Sect. 3, I offer an in-depth analysis of this principle and identify its core as the requirement of self-unification, i.e., the requirement that time-consciousness unifies itself in flowing without any higher-order act of unification. Section 4 then argues that pure intentionalism can satisfy this requirement by embracing dialethism. I conclude by noting how the dialethic account of time-consciousness incorporates a central extensionalist insight within an intentionalist outlook. (shrink)

Branching space-times (BST; Belnap, Synthese 92:385–434, 1992 ) is the most advanced formal framework for representing indeterminism. BST is however based on continuous partial orderings, while our natural way of describing indeterministic scenarios may be called discrete. This paper establishes a theorem providing a discrete data format for BST: it is proved that a discrete representation of indeterministic scenarios leading to BST models is possible in an important subclass of cases. This result enables the representation of limited indeterminism in BST (...) and hopefully paves the way for the representation of substances with capacities in that framework. (shrink)

This monograph is a detailed study, and systematic defence, of the Growing Block Theory of time (GBT), first conceived by C.D. Broad. The book offers a coherent, logically perspicuous and ideologically lean formulation of GBT, defends it against the most notorious objections to be found in the extant philosophical literature, and shows how it can be derived from a more general theory, consistent with relativistic spacetime, on the pre-relativistic assumption of an absolute and total temporal order. -/- The authors (...) devise axiomatizations of GBT and its competitors which, against the backdrop of a shared quantified tense logic, significantly improves the prospects of their comparative assessment. Importantly, neither of these axiomatizations involves commitment to properties of presentness, pastness or futurity. The authors proceed to address, and defuse, a number of objections that have been marshaled against GBT, including the so-called epistemic objection according to which the theory invites skepticism about our temporal location. The challenge posed by relativistic physics is met head-on, by replacing claims about temporal variation by claims about variation across spacetime. -/- The book aims to achieve the greatest possible rigor. The background logic is set out in detail, as are the principles governing the notions of precedence and temporal location. The authors likewise devise a novel spacetime logic suited for the articulation, and comparative assessment, of relativistic theories of time. The book comes with three technical appendices which include soundness and completeness proofs for the systems corresponding to GBT and its competitors, in both their pre-relativistic and relativistic forms. -/- The book is primarily directed at researchers and graduate students working on the philosophy of time or temporal logic, but is of interest to metaphysicians and philosophical logicians more generally.

Russell and Strawson sparked a well known debate on the subject of Linguistic Presupposition inspiring many linguists and philosophers to follow suit, including Frege, whose work initiated the modern study in this area. Beaver begins with the most comprehensive overview and critical discussion of this burgeoning field published to date. He then goes on to motivate and develop his own account based on a Dynamic Semantics. This account is a recent line of theoretical work in which the Tarskian emphasis on (...) truth conditions is questioned. The central plank of the theory of meaning is a formal account of the change in information effected by use of language on hearers or readers. The proposal thus consolidates ideas of Stalnaker, Karttunen and Heim, all of whom had suggested that such an account was needed. At the same time it provides a new impulse and motivation to Dynamic Semantics itself. (shrink)

This paper expresses certain qualms about causal theories of time, Such as have been put forward by h. Mehlberg and adolf gruenbaum. These qualms arise from doubts about the clarity of the notion of causality. It is suggested that a metalinguistic concept of causality cannot occur within the object language of physics, And that any non-Metalinguistic concept of causality leads to more difficulties than do the concepts of physical geometry which a causal theory of time is supposed (...) to elucidate.

Should we try to live in the present? Such is the imperative of modernity, Jed Rubenfeld writes in this important and original work of political theory. Since Jefferson proclaimed that 'the earth belongs to the living', since Freud announced that mental health requires people to 'get free of their past', since Nietzsche declared that the happy man is the man who 'leaps into the moment', modernity has directed its inhabitants to live in the present, as if there alone could they (...) find happiness, authenticity, and above all freedom. But this imperative, Rubenfeld argues, rests on a profoundly inadequate, deforming picture of the relationship between freedom and time. Instead, Rubenfeld suggests, human freedom, indeed human being itself, necessarily extends into both past and future; self-government consists of giving our lives meaning and purpose over time. From this conception of self-government, Rubenfeld derives a new theory of constitutional law's place in democracy. Democracy, he writes, is not a matter of governance by the present 'will of the people'; it is a matter of a nation's laying down and living up to enduring political and legal commitments. Constitutionalism is not coun. (shrink)

It is commonly held that there is no place for the 'now’ in physics, and also that the passing of time is something subjective, having to do with the way reality is experienced but not with the way reality is. Indeed, the majority of modern theoretical physicists and philosophers of physics contend that the passing of time is incompatible with modern physical theory, and excluded in a fundamental description of physical reality. This book provides a forceful rebuttal of (...) such claims. In successive chapters the author explains the historical precedents of the modern opposition to time flow, giving careful expositions of matters relevant to becoming in classical physics, the special and general theories of relativity, and quantum theory, without presupposing prior expertise in these subjects. Analysing the arguments of thinkers ranging from Aristotle, Russell, and Bergson to the proponents of quantum gravity, he contends that the passage of time, understood as a local becoming of events out of those in their past at varying rates, is not only compatible with the theories of modern physics, but implicit in them.

Ulrich Meyer's book The Nature of Time uses tense logic to argue for a `modal' view of time, which replaces substantial times with `ersatz times' constructed using conceptually basic tense operators. He also argues against Bertrand Russell's relationist theory, in which times are classes of events, and against the idea that relativity compels the integration of time and space. I find fault with each of these negative arguments, as well as with Meyer's purported reconstruction of empty spacetime (...) from tense operators and substantial spatial points. I suggest that Meyer's positive project is best conceived as an elimination of time in the mode of Julian Barbour's The End of Time. (shrink)
