It is customary in current philosophy of time to distinguish between an A- (or tensed) and a B- (or tenseless) theory of time. It is also customary to distinguish between an old B-theory of time, and a new B-theory of time. We may say that the former holds both semantic atensionalism and ontological atensionalism, whereas the latter gives up semantic atensionalism and retains ontological atensionalism. It is typically assumed that the B-theorists have been induced by advances in the philosophy of (...) language and related A-theorists’ criticisms to acknowledge that semantic atensionalism can hardly stand, but have also maintained that what is essential for the B-theory is ontological atensionalism, which can be independently defended. Here it is argued that the B-theorists have been too quick in abandoning semantic atensionalism: they can still cling to it. (shrink)

This paper motivates and develops a new theory of time: priority presentism. Priority presentism is the view according to which (i) only present entities exist fundamentally and (ii) past and future entities exist, but they are grounded in the present. The articulation of priority presentism is an exercise in applied grounding: it draws on concepts from the recent literature on ontological dependence and applies those concepts in a new way, to the philosophy of time. The result, as I will argue, (...) is an attractive position that can do much of the same work in satisfying our intuitions about time as presentism, but without the ontological cost. (shrink)

The most important argument against the B-theory of time is the paraphrase argument. The major defense against that argument is the “new” tenseless theory of time, which is built on what I will call the “indexical reply” to the paraphrase argument. The move from the “old” tenseless theory of time to the new is most centrally a change of viewpoint about the nature and determiners of ontological commitment. Ironically, though, the new tenseless theorists have generally not paid enough sustained, direct (...) attention to that notion. I will defend a general criterion of ontological commitment and apply it to generate a version of the new tenseless theory of time. I will argue that many of the extant versions of the new tenseless theory of time (specifically, all those which seek to identify tenseless truth-conditions of tensed sentences as a way out of apparent ontological commitment to tensed features of reality) are unsatisfactory because their general criterion of ontological commitment is inadequate. Those versions of the new tenseless theory which are adequate (specifically, those which identify tenseless truthmakers for tensed sentences) actually entail the criterion of ontological commitment that I defend, despite appearances to the contrary.

Relativity allegedly contradicts presentism, the dynamic view of time and reality, according to which temporal passage is conceived of as an existentially distinguished ‘moving’ now. Against this common belief, the paper motivates a presentist interpretation of spacetime: It is argued that the fundamental concept of time—proper time—cannot be characterized by the earlier-later relation, i.e., not in the B-theoretical sense. Only the presentist can provide a temporal understanding of the twins’ paradox and of universes with closed timelike curves.

Concerning the versions of the Tenseless Theory of Time, the Old Btheory has two: the Date-analysis version and the Token-reflexive version, while the New B-theory has three: the Date-analysis, the Token-reflexive and the Sentence-type versions. Each of these five versions of the B-theory has received serious attacks from the A-theorists, some of whom even claim that the tenseless theory “though still widely held, is a theory in retreat” (Craig 1996), and that “if Quentin Smith (1993) delivered the mortal blow to (...) the New B-Theory of Language then Laurie Paul (1997) has written its obituary” (Craig 1999). In this paper, by making more precise some key notions involved in the formulation of a tenseless theory – in particular, two notions of truth conditions, two notions of meaning and two notions of translation are distinguished – I have come up with a single B-thesis for the B-theory. When charitably interpreted, the two versions of the old theory and the three versions of the new theory can all be regarded as special ways of presenting the same B-thesis, and the various A-attacks raised against these versions can then be resolved in a systematic way.

For twenty years, D. H. Mellor has promoted an influential defence of a view of time he first called the ‘tenseless’ view, but now associates with what he calls the ‘B-theory.’ It is his defence of this view, not the view itself, which is generally taken to be novel. It is organized around a forcefully presented attack on rival views which he claims to be a development of McTaggart's celebrated argument that the ‘A-series’ is contradictory. I will call this attack (...) ‘Mellor's McTaggart.’ Although it has received much critical attention, it has not been well understood. For one thing, it has changed over the years in a way that is little appreciated. Whereas Mellor's original version amounts to a dilemma each horn of which contains a single strand of argument, later statements of the first horn contain a second strand of argument unannounced. I shall be concerned to disentangle these strands. I shall also show them to have been largely anticipated by Gareth Evans. However, my main aim is not the clarification of Mellor's McTaggart, but its refutation. I shall show that there is a rival to Mellor's view of time against which the first horn of the dilemma begs the question both as originally presented, and as supplemented. This rival is a ‘Priorean’ version of the ‘presentist’ doctrine that only what is present exists. Although Prior himself gave McTaggart's own argument short shrift, in refuting Mellor's development of it I do not merely resurrect Prior's moves. Mellor's McTaggart introduces specifically semantic considerations. It focuses not as McTaggart did on presentness and futurity etc., but on the truth-values of tokens of propositions in which presentness and futurity etc. are ascribed. Consequently, its refutation requires an answer, from the perspective of a presentist metaphysics, to a question which came to the fore only after Prior's death. The question is this: How should semantic theory be developed in the light of the need for a theory of linguistic understanding? Though Evans flirted with the issue of how this question should be answered from a presentist perspective, the answer he articulates is wrong. I shall do no more than sketch the correct answer. That is all a refutation of Mellor's McTaggart requires. (shrink)

But this picture of a ‘block universe’, composed of a timeless web of ‘world-lines’ in a four-dimensional space, however strongly suggested by the theory of relativity, is a piece of gratuitous metaphysics. Since the concept of change, of something happening, is an inseparable component of the common-sense concept of time and a necessary component of the scientist's view of reality, it is quite out of the question that theoretical physics should require us to hold the Eleatic view that nothing happens (...) in ‘the objective world’. Here, as so often in the philosophy of science, a useful limitation in the form of representation is mistaken for a deficiency of the universe. (shrink)

Abstract Some fictions, it seems, represent the future as closed, in the sense that some future-tensed propositions are true in those fictions. Yet it is surprisingly difficult to accommodate this plausible thesis within an account of truth in fiction. A number of putative examples of closed fictional futures are discussed (Macbeth, Oedipus, Time and the Conways, The Time Machine) and the problems encountered in reconciling them with various accounts of truth in fiction (David Lewis', Gregory Currie's, Alex Byrne's) elaborated. Connections (...) are drawn between metaphysical views on time and theories of fiction, and an attempt is made to show how the tenseless theory of time (roughly, the denial that time flows) can illuminate accounts of fictional truth, and in particular the issue of how there can be true beliefs about what will happen in a fiction. (shrink)

This paper presents a new argument against A-theories of time. A-theorists hold that there is an objective now (present moment) and an objective flow of time, the latter constituted by the movement of the objective now through time. A-theorists therefore want to draw different pictures of reality—showing the objective now in different positions—depending upon the time at which the picture is drawn. In this paper it is argued that the times at which the different pictures are drawn may be taken (...) to be normal times or hypertimes. If they are normal times then the A-theory is inconsistent, or else collapses to the B-theory—and appealing to primitive tense operators will not help A-theorists avoid this conclusion. If the times are hypertimes then the A-theory is consistent, but deeply problematic none the less. (shrink)

According to the B-theory, the passage of time is an illusion. The B-theory therefore requires an explanation of this illusion before it can be regarded as fullysatisfactory; yet very few B-theorists have taken up the challenge of trying to provide one. In this paper I take some first steps toward such an explanation by first making a methodological proposal, then a hypothesis about a key element in the phenomenology of temporal passage. The methodological proposal focuses onthe representational content of the (...) element of experience by virtue of which time seems to pass. The hypothesis involves the claim that the experience of changeinvolves the representation of something enduring, rather than perduring, through any change. (shrink)

In this paper I distinguish interpretations of the question ``How fast does time pass?’’ that are important for the debate over the reality of objective becoming from interpretations that are not. Then I discuss how one theory that incorporates objective becoming—the moving spotlight theory of time—answers this question. It turns out that there are several ways to formulate the moving spotlight theory of time. One formulation says that time passes but it makes no sense to ask how fast; another formulation (...) says that time passes at one second per supersecond; and a third says that time passes at one second per second. I defend the intelligibility of this final version of the theory. (shrink)

The aim of this paper is to defend a prototype B-theory answer to McTaggart’s Puzzle about Time. Smart hopes to solve the issue by pointing to the “anthropocentricity” of temporal A-notions. There is one important problem: explaining Prior cases (for instance being relieved that a painful experience is over ) in B-theoretic terms. First, it is argued that the problem is how to explain the nature of the subject’s tensed belief in Prior cases; the essential indexicality of the concept ‘ (...) now ’. Then it is suggested that Smart could utilize Burge’s framework for dealing with de re beliefs and a way of formalizing tensed beliefs is proposed. The last section of the paper deals with the exact role of the formalized indexical element. If these three steps are worked out, we might have an explanation of the facts involved in Prior cases without mentioning any A-facts. Hence an important problem to a Smart-influenced B-theory is solved, and McTaggart’s Puzzle answered in an adequate manner. (shrink)

Abstract This paper compares Heidegger's conception of time with more prevalent physical and broadly psychological analyses of time. The ?vulgar? notion of time, as Heidegger understands it, is based on the assumption that time, regardless of whether it is identified with tense or not, is something that is essentially measurable by clocks. Heidegger maintains that the vulgar notion of time is a distortion of his own preferred conception of temporality. I show how temporality may be understood as the non?sequential tensed (...) structure underlying tensed discourse. I argue against any straightforward reduction of this tensed structure and the direction of time to physical occurrences. Nevertheless I argue that temporality can be distinguished from purely psychological analyses of temporal experience and from traditional conceptions of time as tensed experience. The selectiveness of demonstrative discourse provides the basis for Heidegger's critique and reconstruction of time understood as tensed discourse about things. Heidegger's scepticism about the interpretation of time as a sequence of nows that underlies the dominant interpretation of tense is due to his appropriation of the relativity of simultaneity from special relativity. But his interpretation of physical theory leads him to the thesis that time is pre?supposed but not completely analysed in physical theory. The meta?language of physical theory makes covert use of temporal notions, for entities can themselves only be understood in covertly temporal ways. I show how this claim may be understood and defended in the light of current physical theory. Heidegger's analysis gives us some basis for thinking that his own notion of temporality is built into an understanding of temporal experience. But I argue that Heidegger fails to make the case that physical time is ontologically dependent on human existence. (shrink)

RÉSUMÉ: Selon une ontologie platonicienne, il faut qu’une exemplification platonicienne lie des particuliers physiques et un universel non localisé pour qu’i! y ait connexion entre propriété et choses. Dans cet article, je discute du lien d’exemplification platonicien, lequel a l’intéressante faculté de lier des entités localisées à une entité non localisée et donc, pour reprendre les mots d’Armstrong, la faculté de traverser le domaine du non spatialement localisé et celui du spatialement localisé. La littérature ne contient à peu près aucune (...) discussion de l’exemplification. J’en discute et signale une nouveau problème relatif à la connexion entre un universel platonicien et des particuliers physiques. (shrink)

I consider whether the self-ascription theory can succeed in providing a tenseless (B-theoretic) account of tensed belief and timely action. I evaluate an argument given by William Lane Craig for the conclusion that the self-ascription account of tensed belief entails a tensed theory (A-theory) of time. I claim that how one formulates the selfascription account of tensed belief depends upon whether one takes the subject of selfascription to be a momentary person-stage or an enduring person. I provide two different formulations (...) of the self-ascription account of tensed belief, one that is compatible with a perdurantist account of persons and the other that is compatible with an endurantist account of persons. I argue that a self-ascription account of tensed beliefs for enduring subjects most plausibly involves the self-ascription of relations rather than properties. I argue that whether one takes the subject of self-ascription to be a momentary personstage or an enduring person, the self-ascription theory provides a plausible B-theoretic account of how tensed belief and timely action are possible.

Frege held that indexical thoughts could be retained through changes of context that required a change of indexical term. I argue that Frege was partially right in that a singular mode of presentation can be retained through changes of indexical. There must, however, be a further mode of presentation that changes when the indexical term changes. This suggests that indexicals should be regarded as complex demonstratives; a change of indexical term is like a change between 'that φ' and 'that ψ', (...) where 'φ' and 'ψ' pick out relational properties that may nonetheless be conceived of by the thinker as intrinsic. (shrink)

Since McTaggart first proposed his paradox asserting the unreality of time, numerous philosophers have attempted to defend the tensed theory of time against it. Certainly, one of the most highly developed and original is that put forth by Quentin Smith. Through discussing McTaggart's positive conception of time as well as his negative attack on its reality, I hope to clarify the dispute between those who believe in the existence of the transitory temporal properties of pastness, presentness and futurity, and those (...) who deny their existence. We shall see that the debate centers around the ontological status of succession and the B-relations of earlier and later. I shall argue that Smith's tensed theory fails because he cannot account for the sense in which events have their tensed properties successively, and he cannot account for the direction of time. (shrink)

Tenseless theories of time entail that earlierthan, later than and simultaneous with (i.e.,McTaggart's `B-series') are the only temporalproperties exemplified by events. Such theories oftencome under attack for being unable to satisfactorilyaccount for tensed language. In this essay I arguethat tenseless theories of time are capable of twofeats that critics, such as Quentin Smith, argue arebeyond their grasp: (1) They can coherently explainthe impossibility of translating all tensed sentencesby tenseless counterparts; (2) They can account forcertain obviously valid entailment relations betweentensed sentence (...) types. In analyzing tensed entailmentrelations tenselessly, I favor a date analysis oftensed language over a token-reflexive theory. Theupshot is that tenseless theories of time are notundermined by the linguistic facts. (shrink)

McTaggart's argument for the unreality of time is generally believed to be a self-contained argument independent of McTaggart's idealist ontology. I argue that this is mistaken. It is really a demonstration of a contradiction in the appearance of time, on the basis of certain a priori ontological axioms, in particular the thesis that all times exist in parity. When understood in this way, the argument is neither obscure or unfounded, but arguably does not address those versions of the A-theory that (...) deny that all times exist in parity. (shrink)

Leibniz's philosophy of time, often seen as a precursor to current forms of relationalism and causal theories of time, has rightly earned the admiration of his more recent counterparts in the philosophy of science. In this article, I examine Leibniz's philosophy of time from a new perspective: the role that tense and non-tensed temporal properties/relations play in it. Specifically, I argue that Leibniz's philosophy of time is best (and non-anachronistically) construed as a non-tensed theory of time, one that dispenses with (...) tensed temporal properties such as past, present, and future. In arguing for this thesis, I focus on the three facets of Leibniz's philosophy most relevant for evaluating his commitment to a B-theory of time: (1) the nature of change, (2) the reality of the future, and (3) the truth-conditions for tensed temporal statements. Despite prima facie evidence to the contrary, I show that a close examination of Leibniz's views on these topics provides compelling evidence for interpreting his philosophy of time as a B-theory of time. (shrink)

Abstract: A theory of time is a theory of the nature of temporal reality, and temporal reality determines the truth-value of temporal sentences. Therefore it is reasonable to ask how a theory of time can account for the way the truth of temporal sentences is determined. This poses certain challenges for both the A theory and the B theory of time. In this paper, I outline an account of temporal sentences. The key feature of the account is that the primary (...) bearers of truth-values are not utterances, but sentences evaluated with respect to a time. I argue that unlike other views, the present proposal can meet the challenges faced both by the A and the B theory. (shrink)

Information modeling (also known as conceptual modeling or semantic data modeling) may be characterized as the formulation of a model in which information aspects of objective and subjective reality are presented (the application), independent of datasets and processes by which they may be realized (the system).A methodology for information modeling should incorporate a number of concepts which have appeared in the literature, but should also be formulated in terms of constructs which are understandable to and expressible by the system user (...) as well as the system developer. This is particularly desirable in connection with certain intimate relationships, such as being the same as or being a part of. (shrink)

This is an expanded and revised discussion of the argument briefly put forward in my 'A New Problem for the A-Theory of Time', where it is claimed that it is impossible to experience real temporal passage and that no such phenomenon exists. In the first half of the paper the premises of the argument are discussed in more detail than before. In the second half responses are given to several possible objections, none of which were addressed in the earlier paper. (...) There is also some discussion of some related epistemic arguments against the passage of time given by Huw Price and David Braddon-Mitchell along with objections raised against them recently by Tim Maudlin and Peter Forrest respectively.

McTaggart’s paradox and his A-theory and B-theory are basic notions in the contemporary philosophy of time. It is well known that the paradox was introduced by McTaggart’s paper called “The Unreality of Time” published in 1908, so that it has a one-hundred-year history. As for A-theory and B-theory, in contrast, McTaggart himself didn’t consider both of them at all. The notions of A-theory and B-theory came much later, 60 years after the paradox. Moreover, they had not been as popularized as (...) they are today until quite recently, at least after the 1990s. This paper aims to trace the origin of the notions of A-theory and B-theory and show how the debates behind them, especially objections to “spatialising time,” form the notions. (shrink)

We care not only about what experiences we have, but when we have them too. However, on the B-theory of time, something’s timing isn’t an intrinsic way for that thing to be or become. Given B-theory, should we be rationally indifferent about the timing per se of an experience? In this paper, I argue that B-theorists can justify time-biased preferences for pains to be past rather than present and for pleasures to be present rather than past. In support of this (...) argument, I appeal to the doctrine of temporal parts or “four-dimensionalism” for short. When held in conjunction with a certain evaluative principle about whose experiences matter, four-dimensionalism reconciles B-theory with some time-biased preferences. (shrink)

As far as our experience goes, we live in a dynamic present. Those two phenomenal features of experience—presentness and dynamism—are obviously connected. However, how they are connected is not obvious at all. In this paper, I criticise the view according to which the former can explain the latter, which I call sophisticated representationalism. My criticism will be based on an ambiguity in the notion of tense found in the philosophical literature, that between the perspectival understanding and the dynamic understanding of (...) tenses. The distinction is not just of independent interest, but it has a role in providing indirect evidence for the claim that the feeling of passage of time should be understood in non-representationalist terms. (shrink)

There are two extant versions of the new tenseless theory of time: the date versionand the token-reflexive version. I ask whether they are equivalent, and if not, whichof them is to be preferred. I argue that they are not equivalent, that the date version isunsatisfactory, and that the token-reflexive version is correct. I defend the token-reflexive version against a string of objections from Quentin Smith. My defence involves a discussion of the ontological and semantic significance of truth conditions, and of (...) the connection between truth and reality on the one hand, and that between truth and meaning on the other. I argue that Smith's objections to the token-reflexive theory stem from his confusing these two aspects of the notion of truth. (shrink)

In this paper I consider two strategies for providing tenseless truth-conditions for tensed sentences: the token-reflexive theory and the date theory. Both theories have faced a number of objections by prominent A-theorists such as Quentin Smith and William Lane Craig. Traditionally, these two theories have been viewed as rival methods for providing truth-conditions for tensed sentences. I argue that the debate over whether the token-reflexive theory or the date theory is true has arisen from a failure to distinguish between conditions (...) for the truth of tensed tokens and conditions for the truth of propositions expressed by tensed tokens. I demonstrate that there is a true formulation of the token-reflexive theory that provides necessary and sufficient conditions for the truth of tensed tokens, and there is a true formulation of the date theory that provides necessary and sufficient conditions for the truth of propositions expressed by tensed tokens. I argue that once the views are properly formulated, the A-theorist’s objections fail to make their mark. However, I conclude by claiming that even though there is a true formulation of the token-reflexive theory and a true formulation of the date theory, the New B-theory nonetheless fails to provide a complete account of the truth and falsity of tensed sentences.

Cognitive science has recently made some startling discoveries about temporal experience, and these discoveries have been drafted into philosophical service. We survey recent appeals to cognitive science in the philosophical debate over whether time objectively passes. Since this research is currently in its infancy, we identify some directions for future research.

Although C. D. Broad's notion of Becoming has received a fair amount of attention in the philosophy-of-time literature, there are no serious attempts to show how to replace the standard 'block' spacetime models by models that are more congenial to Broad's idea that the sum total of existence is continuously increased by Becoming or the coming into existence of events. In the Newtonian setting Broad-type models can be constructed in a cheating fashion by starting with a Newtonian block model, carving (...) chips off the block, and assembling the chips in an appropriately structured way. However, attempts to construct Broad-type models in a non-cheating fashion reveal a number of problematic aspects of Becoming that have not received adequate attention in the literature. The paper then turns to an assessment of the problem and prospects of adapting Becoming models to relativistic spacetimes. The results of the assessment differ in both minor and major ways from the ones in the extant literature. Finally, the paper describes how the causal set approach to quantum gravity promises to provide a mechanism for realizing Becoming, though the form of Becoming that emerges may not conform to any of the versions discussed in the philosophical literature.

: 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)

John Perry has argued that language, thought and experience often contain unarticulated constituents. I argue that this idea holds the key to explaining away the intuitive appeal of the A-theory of time and the endurance theory of persistence. The A-theory has seemed intuitively appealing because the nature of temporal experience makes it natural for us to use one-place predicates like past to deal with what are really two-place relations, one of whose constituents is unarticulated. The endurance view can be treated (...) in a similar way; the temporal boundaries of temporal parts of objects are unarticulated in experience and this makes it seem that the very same entity exists at different times. (shrink)

In the literature on the compatibility between the time of our experience and the time of physics, the special theory of relativity has enjoyed central stage. By bringing into the discussion the general theory of relativity, I suggest a new analysis of the misunderstood notion of becoming, developed from hints in Gödel's published and unpublished arguments for the ideality of time. I claim that recent endorsements of such arguments, based on Gödel's own ‘rotating’ solution to Einstein's field equation, fail: once (...) understood in the right way, becoming can be shown to be both mind-independent and compatible with spacetime physics. Being a neededtertium quidbetween views of time traditionally regarded as in conflict, such a new approach to becoming should also help to dissolve a crucial aspect of the century-old debate between the so-called A and B theories of time. (shrink)

Frege taught us how to understand one form of predication: an atemporal one. There is also a different, temporal form of predication, which I briefly introduce. Accordingly, there are two fundamentally different approaches to time: a reductive one, aiming to account for time in terms of Frege’s atemporal predication, and a non-reductive one, insisting that the temporal form of predication is sui generis, and that time is to be understood in its terms. I do not directly argue for or against (...) reductionism in this paper. Rather, by evaluating the debates on endurantism–perdurantism, A-theory–B-theory, and presentism–eternalism, I argue that these debates, although aiming to be fundamental, largely boil down to mere quarrels between alternative reductive approaches. We should take notice of this fact and reorient ourselves within the debate on time accordingly: the real issue is whether we should reduce or not. I briefly sketch in what sense endurantism, A-theory, and presentism may be developed on a properly anti-reductionist basis. (shrink)

Prior showed that one could be relieved that the exams were over and not that they finished before a certain date or before a certain entity. One might think that these differences in relief are responsive to differences in the world so that there is more to the exams being over than them finishing before a certain date or entity: there is a metaphysical tense. However, some have argued that these issues do not have any implications for the metaphysics of (...) time because they can be explained with an evolutionary account: emotions can have a causal influence on events that come after them but not on events that come before them and so it evolutionarily advantageous that emotions that concern events after them feel and evaluate differently to those that concern events before them. Here I will argue that to date these evolutionary accounts remain insufficient and emotions continue to put pressure on those who deny there is a metaphysical tense. Prior’s case shows that tensed and tenseless emotions differ in appropriateness. This asymmetry of value is not explained by the evolutionary account because whether or not an emotion is tensed is quite independent of whether it comes before or after something. (shrink)

Prior used our emotions to argue that tensed language cannot be translated by tenseless language. However, it is widely accepted that Mellor and MacBeath have shown that our emotions do not imply the existence of tensed facts. I criticise this orthodoxy. There is a natural and plausible view of the appropriateness of emotions which in combination with Prior’s argument implies the existence of tensed facts. The Mellor/MacBeath position does nothing to upset this natural view and therefore is not sufficient to (...) block one drawing conclusions for the metaphysics of time from the nature of our emotions.

A popular critique of the kalām cosmological argument is that one argument for its second premise illicitly assumes a finite starting point for the series of past temporal events, thereby begging the question against opponents. Rejecting this assumption, opponents say, eliminates any objections to the possibility that the past is infinitely old and undermines the IFA’s ability to support premise 2. I contend that the plausibility of this objection depends on ambiguities in extant formulations of the IFA and that we (...) may resolve these ambiguities in a way that does not presuppose a finite staring point. I also argue that this disambiguation allows us to construct an argument demonstrating that the concept of an infinite past entails a contradiction. (shrink)

This paper aims to clarify the connection between the logic of temporal distinctions and the temporal features of propositions. Contra Prior, it argues that the adoption of tense operators does not commit one to the view that propositions can change their truth value over time.

The central claim of this thesis is that concepts, the components from which cognitively significant truth evaluable content (thought) is composed, are unstructured entities an account of whose individuation makes no essential reference to other concepts in the possession of the thinking subject or to any particular means by which the reference of the concept is identified by the thinking subject. This position is called Conceptual Atomism and contrasts with Inferential Role Semantics, according to which concepts are individuated by their (...) inferential roles or their conditions of warranted application. The structure of the argument is as follows. Firstly, a principle called the Transparency Principle is developed. This places constraints on the individuation of concepts across differing contexts. The Transparency Principle is then used to show that Inferential Role Semantics is false because it cannot provide a satisfactory account of cognitive dynamics; that is, of the conditions under which a concept is retained through changes in the epistemic state of the subject over a period of time. A version of Conceptual Atomism is then defended and it is shown that this theory yields the correct individuation of concepts. According to this theory the concepts of an individual subject are individuated in terms of referential episodes, episodes of ongoing reference to an object or property during which it is diachronically transparent to the subject that the same thing is being referred to. The more general notion of a referential practice is then used to account for the sharing of concepts by more than one person. Finally, a novel account of the thoughts expressed using indexical terms is defended in order to show that indexicals present no counterexample to Conceptual Atomism. This account of indexical thoughts is of some consequence in its own right. (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)

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?

A framework for the mind-matter problem in a holistic universe which has no parts is outlined. The conceptual structure of modern quantum theory suggests to use complementary Boolean descriptions as elements for a more comprehensive non-Boolean description of a world without an a priori mind-matter distinction. Such a description in terms of a locally Boolean but globally non-Boolean structure makes allowance for the fact that Boolean descriptions play a privileged role in science. If we accept the insight that there are (...) no ultimate building blocks, the existence of holistic correlations between contextually chosen parts is a natural consequence. The main problem of a genuinely non-Boolean description is to find an appropriate partition of the universe of discourse. If we adopt the idea that all fundamental laws of physics are invariant under time translations, then we can consider a partition of the world into a tenseless and a tensed domain.In the sense of a regulative principle, the material domain is defined as the tenseless domain with its homogeneous time. The tensed domain contains the mental domain with a tensed time characterized by a privileged position, the Now. Since this partition refers to two complementary descriptions which are not given a priori we have to expect correlations between these two domains. In physics it corresponds to Newton 's separation of universal laws of nature and contingent initial conditions Both descriptions have a non-Boolean structure and can be encompassed into a single non-Boolean description.

It is plausible that every true representation is made true by something in the world beyond itself. I believe that a simple fact is the truthmaker of each true proposition. Simple facts are not familiar entities. This lack of familiarity might lead many to regard them with suspicion, to think that including them in one’s ontology is an ad hoc maneuver. Although such suspicion is warranted initially, it is, I believe, ultimately unfounded. In this paper, I first present what I (...) take to be the simplest argument for simple facts. I then clarify what a simple fact is supposed to be by elucidating the way in which such entities are simple and elaborating an account of their nature. The simplest argument for simple facts relies on a premise that is deeply plausible and yet not uncontroversial, so I present a second argument that forgoes this premise. The second argument is more subtle—and shows the relevance to this discussion of unity from complexity, a metaphysical notion of profound importance—and yet leads to the same conclusion: simple facts exist. I end by considering some concerns one might have regarding the existence of simple facts or the fundamental role that I maintain they have in making true our thoughts and claims about the world.
