Two extremely detailed accounts of temporal experience can be found in the work of C. D. Broad. These accounts have been subject to considerable criticism. I argue that, when we look more carefully at Broad’s work, we find that much of this criticism fails to find its target. I show that the objection that ultimately proves troubling for Broad stems from his commitment to two principles: i) the Thin-PSA, and ii) the ‘Overlap’ claim. I use this result to demonstrate that (...) we can learn two extremely important lessons from Broad’s work on temporal experience. -/- The first lesson is that there is a structural problem facing any account that commits to these two principles. This is significant given that a number of recent accounts of temporal experience are so committed. The second lesson is that the problem facing these accounts stems only from commitment to the Thin-PSA and ‘Overlap’, rather than to commitment to a particular conception of how experiences are to be individuated. This, I argue, gives us reason to reject Tye’s recent claim that the problems facing accounts of temporal experience can be dissolved simply by making stipulations about how experiences are to be individuated.

There are two different varieties of question concerning the unity of consciousness: questions about unity at a time, and unity over time. A recent trend in the debate about unity has been to attempt to provide a ‘generalized’ account that purports to solve both problems in the same way. This attempt can be seen in the accounts of Barry Dainton and Michael Tye. In this paper, I argue that there are crucial differences between unity over time and unity at a (...) time that make it impossible to provide a generalized account of unity. The source of these crucial differences is the phenomenon of the ‘continuity of consciousness’. I argue that accounts of unity over time have to provide an account of this continuity, and that there is no phenomenon analogous to continuity in the case of unity at a time. Attention to the continuity of consciousness reveals crucial structural differences between the two varieties of unity. These structural differences make it impossible to provide a generalized account of unity. I show that the problems faced by Dainton’s and Tye’s accounts in the light of the structural differences make their accounts of unity appear far less appealing than they might initially have looked. I conclude by noting that, in the light of the important differences between the two varieties of unity, it is a mistake to attempt to model accounts of unity over time on accounts of unity at a time.

A critical survey of topics that play a central role in contemporary analytic ontology and metaphysics, including, identity, persistence through time, the problem of universals, the notion of ontological commitment, and the boundary between semantic issues and metaphysics proper.

The aim of this paper is to explain how the Heraclitean doctrine of universal flux must be rejected, while the notion of flux should and can be preserved. Against the reductionist account of subjectless change, a modern version of the Heraclitean doctrine advocated by revisionist metaphysics, I argue that (1) the idea of subjectless change is one that can and should be formulated in the established conceptual framework, and (2) subjectlessness is a feature that most aptly characterizes material changes. In (...) essence, I seek to provide a proper accommodation for the notion of flux in a conceptual framework that is traditionally understood (or rather misunderstood) as decidedly excluding it.

We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems (...) to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports. (shrink)

This paper draws attention to a proof of the necessity of identity given by Arthur Prior. In its simplicity, it is comparable to a proof of Quine's, popularised by Kripke, but it is slightly different. Prior's Polish notation is transcribed into a more familiar idiom. Prior's proof is followed by a proof of the necessity of difference, possibly the first such proof in the literature, which is also repeated here and transcribed. The paper concludes with a brief discussion of Prior's (...) views on identity and difference over time. (shrink)

In what sense is the direction of time a matter of convention? In 'The Direction of Time', Hans Reichenbach makes brief reference to parallels between his views about the status of time’s direction and his conventionalism about geometry. In this article, I: (1) provide a conventionalist account of time direction motivated by a number of Reichenbach’s claims in the book; (2) show how forwards and backwards time can give equivalent descriptions of the world despite the former being the ‘natural’ direction (...) of time; and (3) argue that this offers an important middle-ground position between existing realist and antirealist accounts of the direction of time.

The aim of this paper is twofold. First, I would like to bring into the light the almost unexplored Sellars’s theory of particulars. Second, I would like to show its surprising degree of compatibility with the thesis supported by some contemporary tropists, Tropes, Universals and the Philosophy of Mind, Ontos Verlag, 2008; Moltmann, Mind 113:1–41, 2004 and Moltmann, Noûs 47:346–370, 2013). It is difficult to establish whether Sellars possessed an own theory of tropes, developed independently by the classical form it (...) took in Williams 1953, but as a matter of fact the peculiar features of his “complex particulars” model it is very much like Williams’s theory. So much so that to all intents and purposes it represents a tropes variation. One of its strengths is that it is not part of a constituent ontology, since it is essentially developed from a linguistic and phenomenological point of view. It is for these reasons that this theory manages to avoid some of the classic objections to tropes and it shows to be compatible with the argument of Jonathan Lowe’s “proper visibility” as well as with Friederike Moltmann’s exquisitely linguistic interpretation of tropes.

Intuitively, the future is open and the past fixed: there is something we can do about the future but not the past. Some metaphysicians believe that a proper metaphysics of time must vindicate this intuition. Whereas philosophers have focused on the future and the past, the status of the present remains relatively unexplored. Drawing on resources from action theory, I argue that there is something we can do about the present just like there is something we can do about the (...) future. Hence, a proper metaphysics of the open future should allow for an open present as well. I argue that none of the major metaphysics of the open future currently available can accommodate an open present adequately. Finally, I’ll show that, surprisingly, the shrinking block metaphysics can. (shrink)

Totalism is the view that one distribution of well-being is better than another just in case the one contains a greater sum of well-being than the other. Many philosophers, following Parfit, reject totalism on the grounds that it entails the repugnant conclusion: that, for any number of excellent lives, there is some number of lives that are barely worth living whose existence would be better. This paper develops a theory of welfare aggregation—the lexical-threshold view—that allows totalism to avoid the repugnant (...) conclusion, as well as its analogues involving suffering populations and the lengths of individual lives. The theory is grounded in some independently plausible views about the structure of well-being, identifies a new source of incommensurability in population ethics, and avoids some of the implausibly extreme consequences of other lexical views, without violating the intuitive separability of lives.

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

Many contemporary proponents of hylomorphism endorse a version of hylomorphism according to which the form of a material object is a certain kind of complex relation or structure. Structural approaches to form, however, seem not to capture form’s traditional role as the guarantor of diachronic identity, since more “dynamically complex” material objects, such as living organisms, seem to undergo, and survive, various structural changes over the course of their existence. As a result, some contemporary hylomorphists have looked to alternative, non-structural (...) approaches to form. One of the leading non-structural approaches is the powers approach, according to which the form of a material object is a certain kind of power continuously activated in the object or in its material parts. In this paper, I begin by offering an overview and assessment of this powers approach to form. I argue that while the powers approach captures some crucial elements for understanding the nature of more dynamically complex material objects, when we press on the details of the view we find that it actually points to a related, but importantly distinct, third approach to understanding form, according to which the form of a material object is a certain kind of activity or process in which the material object or its parts are continuously engaged. I call this third approach “Hyloenergeism”. In the second half of the paper, I consider what such a view of material objects might look like and what its principal virtues might be. (shrink)

Structural universals are a kind of complex universal. They have been put to work in a variety of philosophical theories but are plagued with problems concerning their compositional nature. In this article, we will discuss the following questions. What are structural universals? Why believe in them? Can we give a consistent account of their compositional nature? What are the costs of doing so?

The concept of instantiation is realized differently across a variety of metaphysical theories. A certain realization of the concept in a given theory depends on what roles are specified and associated with the concept and its corresponding term as well as what entities are suited to fill those roles. In this paper, the classic realization of the concept of instantiation in a one-category ontology of abstract particulars or tropes is articulated in a novel way and defended against unaddressed objections.

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

In this chapter I argue that there can be no mental representation of objective ‘tensed’ features of reality of the kind that might be thought to occur when we experience time passing or think of times as past, present or future, whether or not such features are part of mind-independent reality. This, I hold, has important consequences for metaphysics; but (as will be most relevant to this volume) it is also likely to have important consequences for a correct semantics for (...) tense. In a nutshell, no correct semantics for tense can treat what philosophers call ‘A-properties’ (such as real pastness, presentness or futurity) as semantic values. (shrink)

Reflection on the self's way of being "in" consciousness yields two arguments for a theory of self-reference not based in any way all all on self-cognition. First, I show that one theory of self-reference predicts an experience of the self because the theory inadequately analyzes the semantical facts about indexicality. I construct a dilemma for this cognitivism, which it cannot get out of, for it requires even solitary self-reference to be based on some original self-knowledge, which is not available. I (...) describe my "kinetic model" of unspoken self-reference, and I show how it fits the facts of four forms of consciousness, all of which presuppose self-reference, rather than yield it. Second, a speaker uses the first person pronoun in sentences because she is aware of the unmediated role in agency of the beliefs she would express, and not because she is aware of herself in their content. The cognitive model, in contrast, succumbs to a vicious regress and is exposed as an obstacle to an understanding of consciousness. (shrink)

Consider a toothache, or a feeling of intense pleasure, or the sensation you would have if you looked impassively at an expanse of colour. In each case, the experience can easily be thought to fill time by being present throughout a period. This way of thinking of conscious experience is natural enough, but it is in deep conflict with the view that physical processes are ultimately responsible for experience. The problem is that physical processes are related to durations in a (...) very different way—not by being wholly present at each instant or sub-period, but by having temporal parts that are. There is a choice to be made, therefore, between preserving this common way of thinking of experience and preserving the fundamentality of processes. The first option holds fixed the view of experiences as occurring throughout time and takes this to constrain the category of entity to which they are identical, or upon which they supervene. The second option abandons this common view of experience by taking up a perspective on which we experience things in the world and their properties as existing or occurring a certain way, and mistakenly ascribe this ontological character to our experience as well. The second option is ultimately the better option, however, since only it can make sense of the facts of our experience. (shrink)

Callender [2017] claims that contemporary science demonstrates that there is no objective present and no objective flow of time, especially since all sensed events come from the past, our various senses need different amounts of time to react, and there are enough asymmetries in the physical world to explain our experience of time. This paper holds that, although Callender’s arguments for the subjectivity of the flow of time are unconvincing, the scientific discoveries and arguments he indicates can still be applied (...) to improve theories of the objective flow of time. The paper develops precisely such a theory, one which introduces multiple individual proper presents for all of the objects that make up our world. (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)

Investigation into the reality of time can be pursued within the ontological domain or it can also span human thought and natural language. I propose to approach time by correlating three domains of inquiry: metaphysical time, the human concept of time, and temporal reference in natural language, entertaining the possibility of what I call a ‘horizontal reduction’ and ‘vertical reduction’. I present a view of temporalityL/E as epistemic modality, drawing on evidence from the L domain and its correlates in the (...) E and M domains. On this view, the human concept of time is a complex, ‘molecular’ concept and can be broken down into primitive concepts that are modal in nature, featuring as degrees of epistemic commitment to representations of states of affairs. I present evidence from tensed and tenseless languages and point out its compatibility with the view of real time as metaphysical modality. (shrink)

Philosophers have responded to McTaggart’s famous argument for the unreality of time in a variety of ways. Some of those responses are not easy to evaluate, since they involve, for example, sometimes murky questions concerning whether a certain infinite regress is or is not vicious. In this paper I set out a response that has not, I think, been advanced by any other author, and which, if successful, is absolutely clear-cut. The basic idea is simply that a tensed approach to (...) time can avoid McTaggart’s contradiction, and can also avoid any regress, vicious or otherwise, by specifying the times at which events have different tensed properties in a tenseless fashion — namely, by using dates. This answer to McTaggart’s argument is, however, open to four important objections. The first objection is that my answer to the second part of McTaggart’s argument is incompatible with something that McTaggart takes himself to have proved in the first part of his argument — the claim, namely, that “there can be no change unless some propositions are sometimes true and sometimes false.” The second objection is that the sentences that I claim can be used to specify when an event has a given tensed property do not in fact do so, since they turn out to be purely tenseless sentences. The third objection is that the sentences in question make use of tenseless verbs, and that it is not in fact possible to make sense of such verbs. The fourth and final objection is that it is not really possible to specify, in tenseless terms, when an event has a given tensed property, since dates have to be analyzed using the relation of temporal priority, and that relation, in turn, must be analyzed in terms of the tensed properties of pastness, presentness and futurity, so that the purportedly tenseless specification is implicitly tensed. I argue, however, that none of these four objections can be sustained. (shrink)

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.

As is widely appreciated and easily demonstrated, the notion that we are essentially experiential (or conscious) beings has a good deal of appeal; what is less obvious, and more controversial, is whether it is possible to devise a viable account of the self along such lines within the confines of a broadly naturalistic metaphysical framework. There are many avenues to explore, but here I confine myself to outlining the case for one particular approach. I suggest that we should think of (...) ourselves (or our essential cores) as being composed of experience-producing systems, and that such systems belong to the same self when they have the capacity to contribute to unified streams of consciousness. The viability of this proposal rests in turn on a particular conception of the structure of consciousness, both at and over time; this conception is defended in the first part of the paper..

The article explores the strategy of reconciliation of the idea of objective flow of time with science. In the first part of my paper, I analyze different conceptions of the passage of time and ponder on how we should understand it. The second part is de-voted to the problem whether there is the passage of time in science.

Presentism faces the following well-known dilemma: either the truth-value of past-tense claims depends on the non-existing past and cannot be said to supevene on being, or it supervenes on present reality and breaks our intuition which says that the true past-tense claims should not depend on any present aspect of reality. The paper shows that the solution to the dilemma offered by Kierland and Monton’s brute past presentism, the version of presentism according to which the past is supposed to be (...) both a fundamental and present aspect of reality, is implausible and proposes how to cure presentism: the dillema can be avoided by taking a third road consisting of introducing dynamics into presentism in the form of the real passage of time. Dynamic presentism, which is constructed in such a way, can overcome the dilemma by providing an ontological basis for the past-tense propositions in the form of the real past. Dynamic presentism also offers a rationale for treating the future as being open. (shrink)

Le Poidevin has recently presented an argument that gives rise to a serious problem for relationist theories of space. It appeals to the simple geometrical fact that if A, B and C are three points lying in a straight line, then AB and BC together entail AC. He suggests that an ontological relationship of supervenience must be appealed to to explain this entailment. Given this thesis of supervenience, relationism is implausible. I argue that the problem that Le Poidevin raises for (...) relationism should be rejected, because the thesis of supervenience is false. The latter rests upon what Le Poidevin refers to as ‘The explanatory principle', a principle which he claims to be a natural extension of the truthmaker principle. Contrary to this, I argue that given any plausible theory of truthmaking, the explanatory principle is false. With the rejection of this principle, Le Poidevin's argument against relationism collapses. (shrink)

The aim of this paper is to establish that free agency, which is a capacity of many animals including human beings, is compatible with indeterminism: an indeterministic world allows for the existence of free agency. The question of the compatibility of free agency and indeterminism is less discussed than its mirror image, the question of the compatibility of free agency and determinism. It is, however, of great importance for our self-conception as free agents in our (arguably) indeterministic world. We begin (...) by explicating the notions of indeterminism and free agency and by clarifying the interrelation of free agency and the human-specific notion of free will. We then situate our claim of the compatibility of free agency and indeterminism precisely in the landscape of the current debate on freedom and determinism, exposing an unhappy asymmetry in that debate. Then we proceed to make our case by describing the mathematically precise, physically motivated model of projective simulation, which employs indeterminism as a central resource for agency modeling. We argue that an indeterministic process of deliberation modeled by the dynamics of projective simulation can exemplify free agency under indeterminism, thereby establishing our compatibility claim: Free agency can develop and thrive in an indeterministic world.

I first distinguish several notions that have traditionally been conflated (or otherwise neglected) in discussions of the metaphysics of time. Thus, for example, I distinguish between the passage of time and temporal becoming. The former is, I maintain, a confused notion that does not represent a feature of the world; whereas a proper understanding of the latter provides the key for a plausible and comprehensive account of the nature of temporal reality. There are two general classes of views of the (...) nature of temporal reality; proponents of particular views in both classes attempt to account for the phenomenon of temporal becoming in terms of qualitative change. I argue that any such account – in terms of change – is irredeemably problematic. And so I propound a different account of temporal becoming, based on the notion that temporal reality is transient, which provides the means to characterize intuitively and vividly the significant effects of time on the metaphysical nature of the world. (shrink)

The aim of this paper is to make presentism a dynamic view of reality by basing it on a notion of dynamic existence, that is, on a notion of existence which has a dynamic character. The paper shows that both of the notions of existence which are used in metaphysical theories of time have a static character and, while such a notion is useful for eternalists, it is useless for presentists if they want to make their view able to remain (...) in agreement with our everyday experience and self-consistent. It is demonstrated that both empirical and theoretical arguments indicate that the presentist should replace the notion of this static existence with the notion of a dynamic existence and that this maneuver allows the presentist to treat his/her existential thesis as equivalent to the thesis that time flows. Not only does this strategy allow us to express presentism in a simple, homogenous way which remains in agreement with our experience, but also permits us to solve some of the difficult problems which presentism faces, such as, for example, the objection of triviality and the question about the rate of time passage. Moreover, such an approach to presentism allows us to solve fundamental metaphysical problems concerning time such as the problem of the openness of the future and the fixity of the past, direction of causation, and relations between presentism and persistence through time by endurance. (shrink)

The paper examines the relations between presentism and the thesis concerning the existence of the flow of time. It tries to show that the presentist has to admit the existence of the passage of time and that the standard formulation of presentism as a singular thesis saying that only the present exists is insufficient because it does not allow the inference of the existence of the passage of time. Instead of this, the paper proposes a formulation of presentism with the (...) aid of the notion of becoming; not only does a formulation state the existence of the flow of time in such a way as to avoid the question of the rate of the passage of time, it also allows the inference of the existence of only present things and events. The paper demonstrates that the proposed conception of presentism also has other virtues, such as homogeneity, non-triviality, and ability to express dynamicity of presentists’ image of the world which testify for it.
