What characterizes indexical thinking is the fact that the modes of presentation through which one thinks of objects are context-bound and perspectival. Such modes of presentation, I claim, are mental files presupposing that we stand in certain relations to the reference : the role of the file is to store information one can gain in virtue of standing in that relation to the object. This raises the communication problem, first raised by Frege : if indexical thoughts are context-bound and relation-based, (...) how is it possible to communicate them to those who are not in the same context and do not stand in the right relations to the object? Following Frege, I argue that the solution comes from an important distinction between linguistic and psychological modes of presentation. Psychological modes of presentation are mental files. They are perspectival and context-bound. But linguistic modes of presentation are fixed by the conventions of the language and they are shared by the language users. They are public and serve to coordinate mental files in communication by constraining them to contain the piece of information they encode. In this way communication takes place even though the indexical thoughts entertained by the speaker are, in some sense, private and cannot be shared by the audience. (shrink)

ABSTRACT Tensism is the view that tense is not merely a property of language and the mind, but of the world itself. Perspectivalism extends this idea to all perspectival properties be they person or locational. One challenge that perspectivalism faces is the problem of expressing the contents of the beliefs and utterances of persons that are in other perspectival positions. One proposed solution to this problem is to allow for semantic theories that "realign" the expression of contents so that the (...) contents expressed by persons in other perspectival positions can be re-expressed from one's own perspectival position. In this paper I argue that a similar semantic realignment strategy could be deployed in helping perspectivalists generally come to grips with a puzzle raised by the Special Theory of Relativity. In short, the strategy is to realign the expression of contents in another inertial frame so that they are expressed from within your inertial frame. As we will see, the strategy is not puzzle free.

A joke is amusing if and only if it’s fitting to be amused by it; an act is regrettable if and only if it’s fitting to regret it. Many philosophers accept these biconditionals and hold that analogous ones obtain between a wide range of additional evaluative properties and the fittingness of corresponding responses. Call these the _fit–value biconditionals_. The biconditionals give us a systematic way of recognizing the role of fit in our ethical practices; they also serve as the bedrock (...) of various metaethical projects, such as fitting-attitude analysis of value and the ‘fittingness first’ approach. Yet despite the importance of the biconditionals, there is very little discussion of their proper interpretation. This paper argues that any plausible interpretation of the fit_–_value biconditionals must disarm several kinds of apparent counterexample. For instance, that an achievement is pride-worthy doesn’t imply it is fitting for me to take pride in it because the achievement might not be mine or that of anyone close to me; that a joke is amusing doesn’t imply it is fitting for me to be amused by it for six straight months; and that a person is loveable doesn’t imply it is fitting for me to love him romantically because that person might be my sibling. We consider possible responses to such counterexamples and develop what we consider the most promising interpretation of the biconditionals. The upshot is that certain widespread assumptions about fit and its relation to value and reasons should be reconsidered. (shrink)

Careful scholarship is balanced by original analyses that lead the reader to recognize the limits of meaning, knowledge, and conceptual possibility. The work addresses a host of traditional philosophical problems, among them the nature of space, time, causality, consciousness, the self, other minds, ontology, free will and determinism, and others. The book culminates in a fascinating and profound new understanding of relativity physics and quantum theory.” – Gerhard Preyer, Professor of Philosophy, Goethe-University, Frankfurt am Main, Germany, author of many books including _Concepts of Meaning_, _Beyond Semantics and Pragmatics_, _Intention and Practical Thought_, and _Contextualism in Philosophy_. ●●●●● “[This work’s] goal is of a unique and difficult species: Dr. Bartlett seeks to develop a formal logical calculus on the basis of transcendental philosophical arguments; in fact, he hopes that this calculus will be the formal expression of the transcendental foundation of knowledge.... I consider Dr. Bartlett’s work soundly conceived and executed with great skill.” – C. F. von Weizsäcker, philosopher and physicist, former Director, Max-Planck-Institute, Starnberg, Germany. ●●●●● “Bartlett has written an American “Prolegomena to All Future Metaphysics.” He aims rigorously to eliminate meaningless assertions, reach bedrock, and place philosophy on a firm foundation that will enable it, like science and mathematics, to produce lasting results that generations to come can build on. This is a great book, the fruit of a lifetime of research and reflection, and it deserves serious attention.” — Martin X. Moleski, former Professor, Canisius College, Buffalo, NY, studies of scientific method, the presuppositions of thought, and the self-referential nature of epistemology. ●●●●● “Bartlett has written a book on what might be called the underpinnings of philosophy. It has fascinating depth and breadth, and is all the more striking due to its unifying perspective based on the concepts of reference and self-reference.” – Don Perlis, Professor of Computer Science, University of Maryland, author of numerous publications on self-adjusting autonomous systems and philosophical issues concerning self-reference, mind, and consciousness. ●●●●● ●●●●● The _Critique of Impure Reason: Horizons of Possibility and Meaning_ comprises a major and important contribution to philosophy. Thanks to the generosity of its publisher, this massive 885-page volume has been published as a free open access eBook (3.75MB) as well as an open access printed edition. It inaugurates a revolutionary paradigm shift in philosophical thought by providing compelling and long-sought-for solutions to a wide range of philosophical problems. In the process, the work fundamentally transforms the way in which the concepts of reference, meaning, and possibility are understood. The book includes a Foreword by the celebrated German philosopher and physicist Carl Friedrich von Weizsäcker. ●●●●● In Kant’s _Critique of Pure Reason_ we find an analysis of the preconditions of experience and of knowledge. In contrast, but yet in parallel, the new _Critique_ focuses upon the ways—unfortunately very widespread and often unselfconsciously habitual—in which many of the concepts that we employ _conflict_ with the very preconditions of meaning and of knowledge. ●●●●● This is a book about the boundaries of frameworks and about the unrecognized conceptual confusions in which we become entangled when we attempt to transgress beyond the limits of the possible and meaningful. We tend either not to recognize or not to accept that we all-too-often attempt to trespass beyond the boundaries of the frameworks that make knowledge possible and the world meaningful. ●●●●● The _Critique of Impure Reason_ proposes a bold, ground-breaking, and startling thesis: that a great many of the major philosophical problems of the past can be solved through the recognition of a viciously deceptive form of thinking to which philosophers as well as non-philosophers commonly fall victim. For the first time, the book advances and justifies the criticism that a substantial number of the questions that have occupied philosophers fall into the category of “impure reason,” violating the very conditions of their possible meaningfulness. ●●●●● The purpose of the study is twofold: first, to enable us to recognize the boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. As a consequence, the boundaries of _possible meaning_ are determined. ●●●●● Bartlett, the author or editor of more than 20 books, is responsible for identifying this widespread and delusion-inducing variety of error, _metalogical projection_. It is a previously unrecognized and insidious form of erroneous thinking that undermines its own possibility of meaning. It comes about as a result of the pervasive human compulsion to seek to transcend the limits of possible reference and meaning. ●●●●● Based on original research and rigorous analysis combined with extensive scholarship, the _Critique of Impure Reason_ develops a self-validating method that makes it possible to recognize, correct, and eliminate this major and pervasive form of fallacious thinking. In so doing, the book provides at last provable and constructive solutions to a wide range of major philosophical problems. ●●●●● CONTENTS AT A GLANCE ▪▪▪▪▪ Preface ▪▪▪▪▪ Foreword by Carl Friedrich von Weizsäcker ▪▪▪▪▪ Acknowledgments ▪▪▪▪▪ Avant-propos: A philosopher’s rallying call ▪▪▪▪▪ Introduction ▪▪▪▪▪ A note to the reader ▪▪▪▪▪ A note on conventions ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART I ▪▪▪▪▪ ▪▪▪▪▪ WHY PHILOSOPHY HAS MADE NO PROGRESS AND HOW IT CAN ▪▪▪▪▪ 1 Philosophical-psychological prelude ▪▪▪▪▪ 2 Putting belief in its place: Its psychology and a needed polemic ▪▪▪▪▪ 3 Turning away from the linguistic turn: From theory of reference to metalogic of reference ▪▪▪▪▪ 4 The stepladder to maximum theoretical generality ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART II ▪▪▪▪▪ THE METALOGIC OF REFERENCE ▪▪▪▪▪ A New Approach to Deductive, Transcendental Philosophy ▪▪▪▪▪ 5 Reference, identity, and identification ▪▪▪▪▪ 6 Self-referential argument and the metalogic of reference ▪▪▪▪▪ 7 Possibility theory ▪▪▪▪▪ 8 Presupposition logic, reference, and identification ▪▪▪▪▪ 9 Transcendental argumentation and the metalogic of reference ▪▪▪▪▪ 10 Framework relativity ▪▪▪▪▪ 11 The metalogic of meaning ▪▪▪▪▪ 12 The problem of putative meaning and the logic of meaninglessness ▪▪▪▪▪ 13 Projection ▪▪▪▪▪ 14 Horizons ▪▪▪▪▪ 15 De-projection ▪▪▪▪▪ 16 Self-validation ▪▪▪▪▪ 17 Rationality: Rules of admissibility ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART III ▪▪▪▪▪ PHILOSOPHICAL APPLICATIONS OF THE METALOGIC OF REFERENCE ▪▪▪▪▪ Major Problems and Questions of Philosophy and the Philosophy of Science ▪▪▪▪▪ 18 Ontology and the metalogic of reference ▪▪▪▪▪ 19 Discovery or invention in general problem-solving, mathematics, and physics ▪▪▪▪▪ 20 The conceptually unreachable: “The far side” ▪▪▪▪▪ 21 The projections of the external world, things-in-themselves, other minds, realism, and idealism ▪▪▪▪▪ 22 The projections of time, space, and space-time ▪▪▪▪▪ 23 The projections of causality, determinism, and free will ▪▪▪▪▪ 24 Projections of the self and of solipsism ▪▪▪▪▪ 25 Non-relational, agentless reference and referential fields ▪▪▪▪▪ 26 Relativity physics as seen through the lens of the metalogic of reference ▪▪▪▪▪ 27 Quantum theory as seen through the lens of the metalogic of reference ▪▪▪▪▪ 28 Epistemological lessons learned from and applicable to relativity physics and quantum theory ▪▪▪▪▪ ▪▪▪▪▪ PART IV ▪▪▪▪▪ HORIZONS ▪▪▪▪▪ 29 Beyond belief ▪▪▪▪▪ 30 _Critique of Impure Reason_: Its results in retrospect ▪▪▪▪▪ ▪▪▪▪▪ SUPPLEMENT ▪▪▪▪▪ The Formal Structure of the Metalogic of Reference ▪▪▪▪▪ APPENDIX I ▪▪▪▪▪ The Concept of Horizon in the Work of Other Philosophers ▪▪▪▪▪ APPENDIX II ▪▪▪▪▪ Epistemological Intelligence ▪▪▪▪▪ References ▪▪▪▪▪ Index ▪▪▪▪▪ About the author.

Future-bias is the preference, all else being equal, for negatively valenced events be located in the past rather than the future, and positively valenced ones to be located in the future rather than the past. Strong risk aversion is the preference to pay some cost to mitigate the badness of the worst outcome. People who are both strongly risk averse and future-biased can face a series of choices that will guarantee them more pain, for no compensating benefit: they will be (...) pain pumped. Thus, combining these preferences is rationally impermissible. Dougherty (2011) argues that this gives us reason to think that future-bias is rationally impermissible. This argument, and a similar one presented by Greene and Sullivan (2015), relies on the idea that if several preferences are not rationally combinable, then in the absence of some explanation of why they are not combinable, we should conclude that (at least) one of them is rationally impermissible. We take up this question by, inter alia, reflecting on the empirical results of a study we ran that probes people’s risk averse and future-biased preferences. We argue that the data, in conjunction with other considerations, suggests that we should not infer from the irrationality of the combination of these preferences to the irrationality of one of the preferences singly. We also argue that given the descriptive data about these preferences, there is no reason to think that, if one of them is rationally impermissible, then it is future-bias. (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)

The special theory of relativity (STR) is widely supposed to be in tension with A-theories of time, those giving special significance to the present moment. A-theories are diverse in the features they regard as distinctive of the present, but all agree that there is an absolute fact of the matter about which events have the feature of presentness. Famously, the standard notion of simultaneity operationalised within the theory of relativity is not absolute. If A-theorists accept relativistic physics, they must either (...) refine their A-theory and sever joint presentness from simultaneity (‘conciliatory’ responses to the problem), or supplement standard relativity by adding further spacetime structure that grounds a relation of absolute simultaneity (‘supplementing’ responses). This chapter considers the prospects for such approaches, concluding that while there is no knock-down argument from relativity against the A-theory, attempts to marry the A-theory with STR are more trouble than they are worth.

In this paper I argue that the self-referential component which Searle rightly detects in the truth-conditions of perceptual judgments comes from the perceptual ‘mode' and is not an aspect of the ‘content' of the judgment, contrary to Searle's claim.

Is the overall value of a world just the sum of values contributed by each value-bearing entity in that world? Additively separable axiologies (like total utilitarianism, prioritarianism, and critical level views) say 'yes', but non-additive axiologies (like average utilitarianism, rank-discounted utilitarianism, and variable value views) say 'no'. This distinction is practically important: additive axiologies support 'arguments from astronomical scale' which suggest (among other things) that it is overwhelmingly important for humanity to avoid premature extinction and ensure the existence of a (...) large future population, while non-additive axiologies need not. We show, however, that when there is a large enough 'background population' unaffected by our choices, a wide range of non-additive axiologies converge in their implications with some additive axiology -- for instance, average utilitarianism converges to critical-level utilitarianism and various egalitarian theories converge to prioritiarianism. We further argue that real-world background populations may be large enough to make these limit results practically significant. This means that arguments from astronomical scale, and other arguments in practical ethics that seem to presuppose additive separability, may be truth-preserving in practice whether or not we accept additive separability as a basic axiological principle.

There are two kinds of time-bias: near-bias and future-bias. While philosophers typically hold that near-bias is rationally impermissible, many hold that future-bias is rationally permissible. Call this normative hybridism. According to arbitrariness objections, certain patterns of preference are rationally impermissible because they are arbitrary. While arbitrariness objections have been levelled against both near-bias and future-bias, the kind of arbitrariness in question has been different. In this paper we investigate whether there are forms of arbitrariness that are common to both kinds (...) of preferences, and hence whether there are versions of the arbitrariness objection that are objections both to near-bias and future-bias. If there are, then this might go some way towards undermining normative hybridism and to defending a thorough-going time-neutralism. (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.

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.

Anti-exceptionalism about logic takes logical theories to be continuous with scientific theories. Scientific theories are subject to criteria of theoretical equivalence. This article compares two types of theoretical equivalence – one syntactic and one semantic – in the context of logical anti-exceptionalism, and argues that the syntactic approach leads to undesirable consequences. The anti-exceptionalist should therefore take a semantic approach when evaluating whether logical theories, understood as scientific theories, are equivalent. This article argues for a particular semantic approach, in terms (...) of categorical equivalence, to determine whether logical theories are equivalent. (shrink)

I show how non-presentists ought to respond to a popular objection originally due to Arthur Prior and lately updated by Dean Zimmerman. Prior and Zimmerman say that non-presentism cannot account for the fittingness of certain emotional responses to things past. But presentism gains no advantage here, because it is equally incapable of accounting for the fittingness of certain other emotional responses to things past, in particular moral outrage.

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)

This paper argues that applying a mental files framework for singular thought to thoughts about specific times could produce an account of tensed thought with significant advantages over competing theories. After describing the framework , I argue for the conceivability of treating particular times as res of singular thoughts , and the possibility that humans open ‘object files’ for them during perception . Then I discuss the possible make-up and function of a NOW indexical mental file . The last section (...) argues that, if our ‘now’ thoughts can be coherently analysed as thinking of a time under the NOW mental file, one would have a plausible explanation of the following issues: how tensed thought can refer to extended temporal intervals of various length; why reference to times is not destroyed by thought delays; and how a ‘now’ thought results in timely actions and, sometimes, relief. (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.

Sceptics about substantial disputes in ontology often argue that when two philosophers seem to disagree on a quantified claim, they are actually equivocating on the notion of existence that they are using. When temporal elements play a central role, as in the debate between presentists and eternalists, the hypothesis of an equivocation with respect to existence acquires more plausibility. However, the anti-sceptic can still argue that this hypothesis is unjustified.

Temporal aspects dwell both in the world around us and at the core of our experience of it. Reality, thought, and language all seem to be imbibed in temporality at some level or another. It is thus not surprising that philosophers who have to face the problems of understanding time have resorted to tools from different spheres of investigation, and often at the points of overlap of these areas. Metaphysics, philosophy of physics and science in general, philosophy of language, phenomenology, (...) philosophy of mind, the study of perception and cognition, but also anthropology, sociology, and history of culture, art, and ideas all contain theories and reflections that are crucial to our understanding and experience of time. Many recent debates in analytic philosophy have tackled in different ways the question of whether the sensation of the passage of time that seems to characterise our ordinary experience should be understood as reflecting some obje ..

A bias against the past is a feature of our Zeitgeist , and has a number of manifestations. One of these is the dominant model of rational agency as geared towards producing effects or outcomes, a model which cannot make sense of the cogency of backward-looking reasons for action. I discuss the nature of such reasons, and the way of perceiving and understanding the past which goes with them. This mode of understanding the past is one of the things that (...) gives substance to the idea that the past has a reality lacked by the future, a reality which among other things makes the past a possible object of contemplation . Such contemplation is a crucial component of eudaimonia. (shrink)

I describe a thought experiment in which an agent must choose between suffering a greater pain in the past or a lesser pain in the future. This case demonstrates that the ‘temporal value asymmetry’ – our disposition to attribute greater significance to future pleasures and pains than to past – can have consequences for the rationality of actions as well as attitudes. This fact, I argue, blocks attempts to vindicate the temporal value asymmetry as a useful heuristic tied to the (...) asymmetry of causation. Since the two standard arguments for the rationality of the temporal value asymmetry appeal to causal asymmetry and the passage of time respectively, the failure of the causal asymmetry explanation suggests that the B-theory, which rejects temporal passage, has substantial revisionary implications concerning our attitudes toward past and future experience. (shrink)

It is often assumed that an eternalist and a presentist will have the same emotional response to life's events because, regardless of one's metaphysical beliefs, we all have the same phenomenological experience of time passing and it is this experience that is relevant to emotional response. I question the assumption that beliefs about the metaphysics of time can have little impact on one's emotional responses and establish the position that scientific and metaphysical beliefs can offer succour.

In this paper, I explore the connection between certain metaphysical views of time and emotional attitudes concerning one’s own death and mortality. I argue that one metaphysical view of time, B-theory, offers consolation to mortals in the face of death relative to commonsense and another metaphysical view of time, A-theory. Consolation comes from three places. First, B-theory implies that time does not really pass, and as a result one has less reason to worry about one’s time growing short. Second, B-theory (...) entails that there is a real sense in which one’s death does not result in one’s annihilation, and this fact can temper feelings of existential distress. Third, B-theory has the consequence that the benefits one has lost have concrete existence, and this fact can mitigate the emotional significance of the losses of death. (shrink)

Propositional temporalism is the view that there are temporary propositions: propositions that are true, but not always true. Factual futurism is the view that there are futurist facts: facts that obtain, but that will at some point not obtain. Most A-theoretic views in the philosophy of time are committed both to propositional temporalism and to factual futurism. Mark Richard, Jeffrey King and others have argued that temporary propositions are not fit to be the contents of propositional attitudes, or to be (...) the semantic values of natural language utterances. But these discussions have overlooked another role that the A-theorist’s posits struggle to play: the role of facts in explaining other facts. Focusing on the case of action explanation by reasons, this paper presents the challenge that explanation poses for factual futurism. It then brings that challenge to bear against propositional temporalism and the A-theory more generally. My argument saddles the factual futurist with surprising commitments concerning reasons, facts and explanation. The futurist might accept those commitments and pay the price. The alternative – which I prefer – is to reject factual futurism, and with it the A-theory. (shrink)

This paper proposes a new reductive theory of modality, called the moodless theory of modality. This theory, and not modal realism, is the closest modal analogue of the tenseless theory of time. So, if the tenseless theory is true, and the temporality–modality analogy is good, it is the moodless theory that follows. I also argue that the moodless theory, considered on its own, is better than modal realism: arguments often thought to be decisive against modal realism are weak against it.

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?

Philosophical debates about the metaphysics of time typically revolve around two contrasting views of time. On the A-theory, time is something that itself undergoes change, as captured by the idea of the passage of time; on the B-theory, all there is to time is events standing in before/after or simultaneity relations to each other, and these temporal relations are unchanging. Philosophers typically regard the A-theory as being supported by our experience of time, and they take it that the B-theory clashes (...) with how we experience time and therefore faces the burden of having to explain away that clash. In this paper, we investigate empirically whether these intuitions about the experience of time are shared by the general public. We asked directly for people’s subjective reports of their experience of time—in particular, whether they believe themselves to have a phenomenology as of time’s passing—and we probed their understanding of what time’s passage in fact is. We find that a majority of participants do share the aforementioned intuitions, but interestingly a minority do not. (shrink)

Kant’s treatments of incongruent counterparts have been criticized in the recent literature. His 1768 essay has been charged with an ambiguous use of the notion of ‘inner ground’, and his 1770 claim that those differences cannot be apprehended conceptually is thought to be false. The author argues that those two charges rest on an uncharitable reading. ‘Inner ground’ is equivocal only if misread as mapping onto Leibniz notion of quality. Concepts suffice to distinguish counterparts, but are insufficient to specify their (...) spatial forms. Kant’s claims are reasonable and plausible, and have been reaffirmed repeatedly in contemporary discussions of demonstrative identification. (shrink)

One of the objections against the thesis of underdetermination of theories by observations is that it is unintelligible. Any two empirically equivalent theories — so the argument goes—are in principle intertranslatable, hence cannot count as rivals in any non-trivial sense. Against that objection, this paper shows that empirically equivalent theories may contain theoretical sentences that are not intertranslatable. Examples are drawn from a related discussion about incommensurability that shows that theoretical non-intertranslatability is possible.

Some authors claim that ‘I’ and ‘now’ are essential indexicals, in the sense that they cannot be eliminated in favor of other indexicals or nonindexical expressions. This article argues that three indexicals of direction—one for each spatial dimension (e.g., ‘up’, ‘front’, and ‘left’)—must also be regarded essential, insofar as they are used as pure indexicals and not as demonstratives.

This essay analyzes the time of human activity. It begins by discussing how most accounts of action treat the time of action as succession, using Donald Davidson's account of action as illustration. It then argues that an adequate account of action and its determinants, one able to elucidate the ``indeterminacy of action,'' requires an alternative conception of action time. The remainder of the essay constructs a propitious account of the time and determination of action. It does so by critically drawing (...) on Henri Bergson's notion of duration and Martin Heidegger's notion of the teleological dimensionality (past, present, and future) of existence. Whereas Bergson provides valuable insights into the continuity of activity, Heidegger illuminates the determination of action. Combining their insights yields an account of the time of activity that supplements succession with a nonsuccessive temporality: the time of activity is an overlapping continuum of action performances each of which is structured as coming towards an end starting from a motivating state of affairs. The essay concludes with brief thoughts on what justifies calling the nonsuccessive dimensionality of existence a kind of time. (shrink)

This article argues that we should be prudentially and morally biased toward earlier events: other things equal, we should prefer for good events to occur earlier and disprefer for bad events to occur earlier. The argument contends that we should accord at least some credence—if only a small one—to a theoretical package featuring the growing block theory of time and that that package generates a presumptive bias toward earlier events. Rival theoretical packages are considered. Under reasonable allocations of credence to (...) them, the presumptive bias escapes defeat. The argument has several corollaries: other things equal, we should be biased toward the past over the future, the further past over the nearer past, and the nearer future over the further future.

The Epistemic Objection says that certain theories of time imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in the details which avoids this problem, using epistemic safety. The new version has two interesting upshots. First, while Ross Cameron alleges that the Epistemic (...) Objection applies to presentism as much as to theories like the growing block, the safety version does not overgeneralize this way. Second, the Epistemic Objection does generalize in a different, overlooked way. The safety objection is a serious problem for a widely held combination of views: “propositional temporalism” together with “metaphysical eternalism”. (shrink)

In this paper I argue that the growing block theory of time has rather surprising, and hitherto unexplored, explanatory benefits when it comes to certain enduring philosophical puzzles concerning death. In particular, I claim the growing block theorist has readily available and convincing answers to the following questions: Why is it an evil to be dead but not an evil to be not yet born? How can death be an evil for the dead if they no longer exist to suffer (...) it? When is death an evil for the one who dies? The ability to give such answers is a significant, but by no means decisive, advantage for the growing block view of time. (shrink)

Perdurantists hold that we persons—just like other ordinary objects—persist by perduring, by having temporal parts, or stages, located over time. Perdurantists also standardly endorse the B-theory of time. And, in light of this endorsement, they typically characterize our tensed beliefs as self-ascriptions of properties, made not by us but by our stages. For instance, for me to believe that Angela Merkel is currently the chancellor of Germany is for my now-located stage to self-ascribe the property of being simultaneous with Merkel’s (...) chancellorship. The problem with this way of understanding tensed belief is that it undermines—if not outright contradicts—the perdurantist’s best options for resisting the Too Many Thinkers objection. In what follows, I show why this is. I then consider what I take to be the perdurantist’s most promising alternative account of tensed belief. I argue that this alternative either leaves perdurantists no better off with respect to the Too Many Thinkers objection or, instead, leaves them vulnerable to another objection, one that they would otherwise have no problem resisting.

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)

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.

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.

It is a common claim that one concept of time, tenseless theory, is in greater conflict with how the world seems to us than the competing theories of tense theory and presentism. This paper offers at least one counter-example to that claim. Here, it is argued that tenseless theory fares better than its competitors in capturing the phenomenology in particular cases of perception. These cases are where the visual phenomenology is of events occurring together which must be occurring at different (...) times. The commitments of matching such phenomenology in one’s ontology undermine tense theory and presentism and support tenseless theory. (shrink)

I will show how a metaphysical problem of Arthur Prior’s can be solved by a logical tool he developed himself, but did not put to any foundational use: metric logic. The broader context is given by the key question about the metaphysics of time: Is time tenseless, i.e., is time just a structure of instants; or is time tensed, because some facts are irreducibly tensed? I take sides with Prior and the tensed theory. Like him, I therefore I have to (...) deal with a more specific metaphysical question: How can the instants of tenseless time be reduced to tensed facts? This is the point where, on the technical level, hybrid logic and metric logic come in. For present purposes, both can be seen as species of tense logic; and both are creations of Prior. In his argument for the tensed theory of time, Prior used hybrid tense logic to reduce instants. But, as he himself pointed out, this reduction runs into deep problems, because it immediately generalizes to other categories, for example and most importantly to persons. My main aim is to show that metric logic does not run into similar difficulties: It will help the tensed theory reduce instants, but it leaves persons untouched. I will also give reasons for preferring a metric to a hybrid logic of time that are independent of the metaphysical issue of reduction, but concern temporal reasoning, natural language semantics, and the epistemic side of time-keeping.
