This chapter examines the philosophical discussion concerning the relationship between time, memory, attention, and consciousness, from Locke through the Scottish Common Sense tradition, in terms of its influence on James' development of the specious present doctrine. The specious present doctrine is the view that the present moment in experience is non punctate, but instead comprises some nonzero amount of time; it contrasts with the mathematical view of the present, in which the divide between past and future is merely a point (...) or a line with no thickness. The anonymous source for the term 'specious present' is revealed as a retired businessman-turned-amateur philosopher. The more likely source for the idea itself is a little-known philosopher, Shadworth Hollway Hodgson, who was not merely a significant influence on James but also on Husserl's development of the tripartite account of internal time consciousness. I conclude by demonstrating how James' changing views on the relationship between concepts and experience meant that by the later period of his writings, including those in which he develops his own views on pragmatism, James would have not merely noted the contrast between a mathematical conception of the present and our actual experience of it, he would have taken a further step and condoned the thick experience of the present as demonstrating the inadequacy of the intellectualized mathematical characterization.

This paper approaches Husserl’s analysis of time-consciousness from a mereological perspective. Taking as inspiration Bergson’s idea that pure durée is a multiplicity of interpenetration, I will show, from within Husserlian phenomenology, that the absolute flow can indeed be described as a whole of interpenetrating parts. This mereological perspective will inform my re-consideration of the much-discussed issue of Husserl’s self-criticism concerning the schema of content and apprehension. It will also reveal a fundamental similarity between Husserl’s conception of the absolute flow and (...) Sartre’s conception of lived temporality. This paper consists of four sections. Section 2 presents the basic elements of Husserl’s mereology. Section 3 introduces the difficulty encountered by Husserl’s early account of time that makes use of the schema. I will examine Barry Dainton’s criticism of Husserl’s theory of time-consciousness against the background of the older debate between Meinong and Stern, a debate that has informed Husserl’s own account. Section 4 distinguishes two common criticisms of the schema from Husserl’s own self-criticism, which is in turn divided into two steps. It is shown how the second step of this self-criticism implies the interpenetration of the absolute flow and responds to Dainton’s criticism. Finally, Sect. 5 concludes with some comparative remarks. I will show how Husserl’s notion of absolute flow, as mereologically interpreted, anticipates Sartre’s conception of consciousness as self-transcendence, as well as how it accommodates the apparently conflicting mereological intuitions of Aristotle and Bergson.

In this paper, I first introduce one of the most prominent objections against the Growing Block Theory of time (GBT), the so-called ‘epistemic objection’, according to which GBT provides no way of knowing that our time is the objective present and, therefore, leads at best to absolute skepticism about our temporal location, at worst to the quasi-certainty that we are located in the objective past. Secondly, I express my dissatisfaction regarding the various traditional attempts to address this objection, especially Merricks (...) (2006), Forrest (2004) and Correia and Rosenkranz (2018). Thirdly, I show that the passage of time leads to an anti-essentialist picture of natural kinds. Finally, I develop my own solution to the epistemic objection, based on the continued existence of bare particulars. (shrink)

EXPANDED EDITION (eBook): -/- Infinity Is Not What It Seems...Infinity is commonly assumed to be a logical concept, reliable for conducting mathematics, describing the Universe, and understanding the divine. Most of us are educated to take for granted that there exist infinite sets of numbers, that lines contain an infinite number of points, that space is infinite in expanse, that time has an infinite succession of events, that possibilities are infinite in quantity, and over half of the world’s population believes (...) in a divine Creator infinite in knowledge, power, and benevolence. -/- According to this treatise, such assumptions are mistaken. In reality, to be is to be finite. The implications of this assessment are profound: the Universe and even God must necessarily be finite. -/- The author makes a compelling case against infinity, refuting its most prominent advocates. Any defense of the infinite will find it challenging to answer the arguments laid out in this book. But regardless of the reader’s position, FOREVER FINITE offers plenty of thought-provoking material for anyone interested in the subject of infinity from the perspectives of philosophy, mathematics, science, and theology. -/- This electronic edition of FOREVER FINITE is offered free online for all and is expanded with content that does not appear in the published edition due to print production page limitations. From the Introduction to the Conclusion, Chapters 1–27 are identical to the published print edition, including the page numbering for the chapters. This electronic edition adds an appendix and associated content—specifically, updates to the book’s back matter (68 new endnotes, 17 new bibliographic references, 3 new figure credits, 14 new glossary terms) and front matter (an updated table of contents and this preface note).

Despite the burgeoning interest in new and more complex accounts of the organism-environment dyad by biologists and philosophers, little attention has been paid in the resulting discussions to the history of these ideas and to their deployment in disciplines outside biology—especially in the social sciences. Even in biology and philosophy, there is a lack of detailed conceptual models of the organism-environment relationship. This volume is designed to fill these lacunae by providing the first multidisciplinary discussion of the topic of organism-environment (...) interaction. It brings together scholars from history, philosophy, psychology, anthropology, medicine, and biology to discuss the common focus of their work: entangled life, or the complex interaction of organisms and environments.

I attempt to set the stage for a constructive analysis of the nature and function of tensed belief as a distinct psychological type. After introducing tensed beliefs, I describe the philosophical issues that implicate them, including Prior’s “ thank goodness it’s over ” argument against the B-theory of time. I proceed to flesh out, and then argue against, two traditional treatments of tensed belief from the philosophy of time: the A-theoretic view, which starts from present facts or properties, and Hugh (...) Mellor's B-theoretic reply, which starts from the tenseless properties of tensed belief tokens. The explanatory failure of the former shows that, pace Prior, the existence of tensed attitudes does not favor the A-theory, while the failure of both shows that there are still explanatory gaps that we need to fill. I conclude by offering a working definition of tensed belief and the ideal methodology for filling out these explanatory gaps in future study. (shrink)

This paper explores the theme “quantum approaches to consciousness” by considering the work of one of the pioneers in the field. The physicist David Bohm not only made important contributions to quantum physics, but also had a long-term interest in interpreting the results of quantum physics and relativity in order to develop a general world view. His idea was further that living and mental processes could be understood in a new, scientifically and philosophically more coherent way in the context of (...) such a new world view. This paper gives a brief overview of different – and sometimes contradictory - aspects of Bohm’s research programme, and evaluates how they can be used to give an account of topics of interest in contemporary consciousness studies, such as analogies between thought and quantum processes, the problem of mental causation, the mind-body problem and the problem of time consciousness.

The new understanding of basic dimensions Absolute Time and Space will open the possibility of exploring beyond our current known Universe. These absolute dimensions might supersede our current Spacetime dimension and related theories. Interpretations based on these dimensions could effectively bridge the gap between theories of microscopic and telescopic worlds and it will eventually give us a better picture of our Universe. This book will take us one step closer towards the understanding of our Entire Existence. As we can see (...) below mentioned are some of the current research related topics in the field of Metaphysics and Cosmology. This book will address all these questions and related subsequent questions of this subject. 1. How our universe came into existence? 2. What was the time before the start of the universe? 3. Is there anything outside of this universe? 4. Is time travel possible? 5. Is there any multiverse or parallel universe? (shrink)

Approaching Infinity addresses seventeen paradoxes of the infinite, most of which have no generally accepted solutions. The book addresses these paradoxes using a new theory of infinity, which entails that an infinite series is uncompletable when it requires something to possess an infinite intensive magnitude. Along the way, the author addresses the nature of numbers, sets, geometric points, and related matters. The book addresses the need for a theory of infinity, and reviews both old and new theories of infinity. It (...) discussing the purposes of studying infinity and the troubles with traditional approaches to the problem, and concludes by offering a solution to some existing paradoxes. (shrink)

Through hearing we learn about source events: events in which objects move or interact so that they vibrate and produce sound waves, such as when they roll, collide, or scrape together. It is often claimed that we do not simply hear sounds and infer what event caused them, but hear source events themselves, through hearing sounds. Here I investigate how the idea that we hear source events should be understood, with a focus on how hearing an event relates to hearing (...) the objects involved in that event. I argue that whereas we see events such as rollings and collisions by seeing objects move through space, this cannot be how we hear them, and go on to examine two other possible models. On the first, we hear events but not their participant objects. On the second, to hear an event is to hear the appearance of an object to change. I argue that neither is satisfactory and endorse a third option: to hear a source event is to hear an object as extending through time. (shrink)

Mereotopology is a theory of connected parts. The existence of boundaries, as parts of everyday objects, is basic to any such theory; but in classical mereotopology, there is a problem: if boundaries exist, then either distinct entities cannot be in contact, or else space is not topologically connected . In this paper we urge that this problem can be met with a paraconsistent mereotopology, and sketch the details of one such approach. The resulting theory focuses attention on the role of (...) empty parts, in delivering a balanced and bounded metaphysics of naive space. (shrink)

My argument proceeds in two stages. In §I, I sum up the intuitions of a popular argument for 'satisfaction accounts' of Purgatory that I label, TAP. I then offer an argument, taken from a few standard orthodox Christian beliefs and one axiom of Christian theology, to so show that TAP is unsound. In the same section, I entertain some plausible responses to my argument that are prima facie consistent with these beliefs and axiom. I find these responses wanting. In §II, (...) I offer a sorites problem for TAP, given the orthodox Christian understanding of Christ’s parousia, showing that TAP and the intuitions driving it are faulty. To attempt something of a corrective, I end by offering some modest theological suggestions for thinking through “the logic of total transformation.”. (shrink)

I will adapt part of an argument in Prosser to the case of persistence, to conclude that our experience does not favour any particular theory of persistence—our immediate experience cannot rightly be considered as evidence in this context. Even if it does in fact seem that objects persist by enduring, this cannot be because they do in fact endure; and if things do in fact persist by perduring, this should not be considered to be in spite of appearances. Thus any (...) explanation for why objects are represented in experience as enduring will be one that is independent of the truth of endurantism. (shrink)

Ostrich presentists maintain that we can use all the expressive resources of the tensed language to provide an explanation of why true claims about the past are true, without thereby paying any price in terms of ontology or basic ideology. I clarify the position by making a distinction between three kinds of explanation, which has general interest and applicability. I then criticize the ostrich position because it requires an unconstrained version of the third form of explanation, which is out of (...) place in metaphysics. (shrink)

For centuries, philosophers of time have produced texts containing words and pictures. Although some historians study visual representations of time, I have not found any history of philosophy on pictures of time within texts. This paper argues that studying such pictures can be rewarding. I will make this case by studying pictures of time in the works of Leibniz, Arthur Eddington and C. D. Broad, and argue they play subtle roles. Further, I will argue that historians of philosophy more widely (...) could benefit from paying more attention to pictures. (shrink)

This paper explores a trans-Atlantic clash about time: in 1899, American philosopher Mary Calkins argued we should not spatialize time; in 1899, British philosopher Victoria Welby argued we should. I take their disagreement as a starting point to contextualize, study, and compare the accounts of time presented in their respective articles. Both Calkins and Welby cared deeply about time, writing on the topic across their careers, but their views have not been studied by historians of philosophy. This is unfortunate, for (...) I argue their novel theories reward attention. Calkins’ 1899 account draws on Kant to arrive at the earliest American-British causal theory of time, pioneers the metaphysical applications of temporal experimental psychology, and replies to F. H. Bradley’s proclamation that it is ‘impossible’ to explain the appearance of time. Meanwhile, I read Welby’s 1907 account as offering a radical metaphysic, on which time is literally a kind of space, resonating with 1880s literature around the ‘fourth dimension’ and H. G. Wells’ 1895 novel The Time Machine. I have uncovered an early draft of Welby’s paper dating to 1902 and, using this alongside other unstudied writings by Welby, trace the development of her views from the 1880s onwards. (shrink)

In the early twentieth century, a rare strain of British idealism emerged which took Leibniz's Monadology as its starting point. This paper discusses a variant of that strain, offered by Hilda Oakeley. I set Oakeley's monadology in its philosophical context and discuss a key point of conflict between Oakeley and her fellow monadologists: the unreality of time. Oakeley argues that time is fundamentally real, a thesis arguably denied by Leibniz and subsequent monadologists, and by all other British idealists. This paper (...) discusses Oakeley's argument for the reality of time, and Oakeley's attack on the most famous account of the unreality of time offered in her day: that of J. M. E. McTaggart. I show that Oakeley's critique of McTaggart can be extended to challenge all monadologists, including that of the great monad, Leibniz himself. (shrink)

Priority pluralism, perdurantism and that temporal gunk – where some interval of time is gunky iff every interval of it has a proper subinterval – is at least metaphysically possible, are three commonly held views in contemporary metaphysics. However, there cannot be a temporally gunky world where objects perdure, and where there are mereological simples. Given that – as I will argue – pluralists should be committed to atomism, and cannot plausibly revise their view to accommodate temporal gunk if they (...) are perdurantists, pluralism is incompatible with the combination of temporal gunk and perdurantism. Therefore, priority pluralism, perdurantism and the possibility of temporal gunk are jointly incompatible, and at least one of these views must be false. Subsequently, it means that at least one of the following views must be true: priority monism or metaphysical infinitism; endurantism; and/or that time is atomistic. The triad's inconsistency, then, has some interesting metaphysical implications. (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.

The Relational Blockworld (RBW) interpretation of non-relativistic quantum mechanics (NRQM) is introduced. Accordingly, the spacetime of NRQM is a relational, non-separable blockworld whereby spatial distance is only defined between interacting trans-temporal objects. RBW is shown to provide a novel statistical interpretation of the wavefunction that deflates the measurement problem, as well as a geometric account of quantum entanglement and non-separability that satisfies locality per special relativity and is free of interpretative mystery. We present RBW’s acausal and adynamical resolution of the (...) so-called “quantum liar paradox,” an experimental set-up alleged to be problematic for a spacetime conception of reality, and conclude by speculating on RBW’s implications for quantum gravity.

This essay presents an alternative to contemporary substantivalist and relationist interpretations of quantum gravity hypotheses by means of an historical comparison with the ontology of space in the seventeenth century. Utilizing differences in the spatial geometry between the foundational theory and the theory derived from the foundational, in conjunction with nominalism and platonism, it will be argued that there are crucial similarities between seventeenth century and contemporary theories of space, and that these similarities reveal a host of underlying conceptual issues (...) that the substantival/relational dichotomy fails to distinguish.

In our wakeful conscious lives, the experience of time and dynamic temporal phenomena—such as continuous motion and change—appears to be ubiquitous. How is it that temporality is woven into our conscious experience? Is it through perceptual experience presenting a series of instantaneous states of the world, which combine together—in a sense which would need to be specified—to give us experience of dynamic temporal phenomena? In this paper, I argue that this is not the case. -/- Several authors have recently proposed (...) dynamic snapshot models of temporal experience— such as Prosser and Arstila, building upon Le Poidevin— according to which perceptual experience has no temporal content of a non‐zero extent. I argue that there is an absence of motivation for such a view; I develop and defend the claim that perceptual experience minimally presents something of some non‐zero temporal extent as such.

As a typical subject, you experience a variety of paradigmatically temporal phenomena. Looking out of the window in the English summer, you can see leaves swaying in the breeze and hear the pitter-patter of raindrops steadily increasing against the window. In discussions of temporal experience, and through reflecting on examples such as those offered, two phenomenological claims are widely – though not unequivocally – accepted: firstly, you perceptually experience motion and change; secondly, while more than a momentary state of affairs (...) is presented in your ongoing perceptual experience, that which is presented nonetheless seems to be of a quite limited temporal extent. These two claims are frequently tied to the notion of the specious present. However, there has recently been a push back against the supposed link between perceived motion and the specious present. I argue that there are two ways of understanding this link, and while one has recently been the target of criticism, the other withstands such criticism. My overarching aim is to clarify the notion of the specious present through a discussion of the notion’s origins, in addition to recent criticism directed at the notion, with the hope of reframing how contemporary debates proceed.

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.

A recently published hypothesis on the nature of time by physicist Richard A. Muller seeks to provide an objective account of the present moment and the ‘flow’ of time. Muller also claims that his hypothesis makes testable predictions. It is shown that the predictions offered cannot be used to test Muller’s hypothesis, that the hypothesis does not rate scientific status, has a number of questionable metaphysical premises, and is merely a re-fashioning of the Growing Block theory of time.

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)

Riemer’s recent paper on the perception of time discusses a neglected yet important topic in the psychological literature: the consequences for psychology (and psychophysics) from the ‘anisotropy’ of time. The paper presents an argument that there are unique kinds of challenges for psychophysics from such temporal anisotropy: (a) Challenges because the psychological experience of time has temporal anisotropy and the physical concept of time does not have temporal anisotropy. (b) Challenges for experimental research which are unique to temporal anisotropy. -/- (...) Although it is important to consider temporal anisotropy, I think there are reasons to deny the force of both kinds of challenges. (shrink)

The doctrine of the specious present, that we perceive or, at least, seem to perceive a period of time is often taken to be an obvious claim about perception. Yet, it also seems just as commonly rejected as being incoherent. In this paper, following a distinction between three conceptions of the specious present, it is argued that the incoherence is due to hidden metaphysical assumptions about perception and time. It is argued that for those who do not hold such assumptions, (...) so long as we are clear about what the doctrine is really saying, we can make perfect sense of the specious present doctrine.

This paper explores what could justify some intuitive temporal asymmetries regarding redemption and the distribution of ills and goods throughout an agent's lifespan. After exposing the inadequacies of causal explanations – based on our differential ability to affect the future, but not the past – a metaphysical explanation is outlined in relation to three competing temporal-ontological profiles of agents, and their varying accounts of a being's development. Only one of those conceptions of agents – supported by Presentism, the thesis that (...) everything is present – offers an account justifying the intuitive temporal asymmetries. Finally, consequences are then drawn for the possibility of true redemption. (shrink)

This paper elaborates the problem of temporal unity for dynamic presentism and diagnoses the source of that problem in the dynamic presentist’s discarding the traditional C-series in its avoidance of McTaggart’s (1908, 1927) A-series paradox. This C-series provided the fixed structure of time which the transitory aspects of time then followed, and thereby unify those transitory aspects. It then considers ersatzer presentism as an ostensible solution to the problem of temporal unity by providing a new abstract C-series (namely an ersatz-B-series) (...) for dynamic presentism. However, after a closer examination of the details of this proposal, it is found that the ersatz-B-series itself needs to be temporally variable to capture the transitory aspects of time that it is meant to track. Consequently, it cannot provide the fixed structure of time required to unify the transitory aspects of time into a temporal series. It is therefore suggested that dynamic presentists look for a more course-grained determiner of temporal progression to construct the presentist-friendly C-series required to unify their transitory aspects of time. (shrink)

This essay outlines an explanatory virtue of presentism: its unique ability amongst temporal metaphysics to deliver a partial explanation of the conservational character of natural laws. That explanation relies on presentism, uniquely amongst temporal metaphysics, being able to support an endurantist account of persistence. In particular, after reconsidering a former argument for endurantism entailing presentism by Merricks (Noûs 33:421-438, 1999), a new argument for this entailment, is expounded. Before delivering the explanation of the conservational character of natural laws, a brief (...) account of that explanandum is given, followed by an elaboration of the wider significance of an explanation for the conservational character for natural laws, particularly for the dispositional essentialist project of nomic reductionism, and explaining the non-simultaneity of causation.

Presentism states that everything is present. Crucial to our understanding of this thesis is how we interpret the ‘is’. Recently, several philosophers have claimed that on any interpretation presentism comes out as either trivially true or manifestly false. Yet, presentism is meant to be a substantive and interesting thesis. I outline in detail the nature of the problem and the standard interpretative options. After unfavourably assessing several popular responses in the literature, I offer an alternative interpretation that provides the desired (...) result. This interpretation is then used to clarify the distinction between ‘real change’ from mere variation and temporal relativisation. Reflecting on my solution, I try to diagnose the source of confusion over these issues. Then, building upon Fine’s distinction between ontic and factive presentism, I elucidate what the presentist thesis specifically concerns and how best to formalise it. In the process I distinguish a weak and strong version of the presentist thesis. Finally, I end by drawing out some limitations of the paper. (shrink)

This paper considers a problem for dynamic presentism that has received little attention: its apparent inability to accommodate the duration of events (such as conscious experiences). After outlining the problem, I defend presentism from it. This defence proceeds in two stages. First, I argue the objection rests on a faulty assumption: that duration is temporal extension. The paper challenges that assumption on several different ways of conceiving of temporal extension. This is the negative case and forms the bulk of the (...) paper. Second, after diagnosing the error leading to the identification of duration with temporal extension, I outline a new presentist-friendly account of duration that avoids the problem. In particular, a non-reductive account of duration is offered that treats it as a primitive quality which bestows its possessor with a certain modal quality: that the possessor potentially does not change whilst there are changes in its environs. This is the positive case. Together the positive and negative cases provide presentism with an interesting and novel way of overcoming the problem of duration. (shrink)

It continues to be alleged that superluminal in uences of any sort would be inconsistent with special relativity for the following three reasons: they would imply the existence of a ‘distinguished’ frame; they would allow the detection of absolute motion; and they would violate the relativity of simultaneity. This paper shows that the first two objections rest upon very elementary misunderstandings of Minkowski geometry and on lingering Newtonian intuitions about instantaneity. The third objection has a basis, but rather than invalidating (...) the notion of faster-than-light influences it points the way to more general conceptions of simultaneity that could allow for quantum nonlocality in a natural way.

The thesis I wish to argue for in this article is that spatial relations such as occupying and being 1 km distant from are external. In the “Section 1” section, I shall introduce the distinction between external and internal relations and some other basic concepts in the ontology of relations. Afterwards, in the subsequent sections, I shall deal with different theories of space: substantivalism and relationism ; the spatial property theory ; super-substantivalism and super-relationism ; and spatial essentialism. I shall (...) demonstrate that, in all such theories, spatial relations need to be considered external. Otherwise, unacceptable consequences or spatial properties that are non-relational by mere façon de parler are in order. Finally, in the “Section 6” section, I shall briefly tackle length contraction in special relativity theory. (shrink)

Mechanisms are organized collections of objects and activities that underlie certain phenomena/behaviours. In this article, I shall argue that the organizations of mechanisms should be thought of as external relations, namely, as relations that do not entirely depend on their relata’s existence, nor on their natures, nor on their intrinsic properties. After having introduced in the first two sections mechanisms and the ontology of relations, I shall analyse the organizations of mechanisms along four different dimensions: spatial, temporal, causal and hierarchical. (...) I shall demonstrate that each dimension requires that organizations be taken as external relations. Finally, in the last section, I shall anticipate and reply to two objections. (shrink)

In a recent paper in this journal, McCall and Lowe (2003) argue that an understanding of Special Relativity reveals that the A theorist’s notion of temporal passage is consistent with the B theory of time. They arrive at this conclusion by considering the twins’ paradox, where one of two twins (T) travels to Alpha Centauri and back and upon her return has aged 30 years, while her earth-bound twin (S) has aged 40 years.Does this reconcile the A theoretic notion of (...) temporal passage with the B theory of time? I argue not. (shrink)

The philosophical investigation of perceptual illusions can generate fruitful insights in the study of subjective time consciousness. However, the way illusions are interpreted is often controversial. Recently, proponents of the so-called dynamic snapshot theory have appealed to the Waterfall Illusion, a kind of motion aftereffect, to support a particular view of temporal consciousness according to which experience is structured as a series of instantaneous snapshots with dynamic qualities. This dynamism is meant to account for familiar features of the phenomenology of (...) time, such as succession, continuity, and change. Previous theories have typically appealed to a subjective present occupying an interval of time; that is, a “specious present.” I argue, through analysis of motion aftereffect illusions and the rare condition of akinetopsia, i.e. motion-blindness, that the Waterfall Illusion fails to support the dynamic snapshot theory as intended. Furthermore, I suggest that future theories of subjective time should see temporal phenomenology as the result of non-localised processes closely tied to the mechanism underlying consciousness generally.

Metaphysicians who are aware of modern physics usually follow Putnam (1967) in arguing that Special Theory of Relativity is incompatible with the view that what exists is only what exists now or presently. Partisans of presentism (the motto ‘only present things exist’) had very difficult times since, and no presentist theory of time seems to have been able to satisfactorily counter the objection raised from Special Relativity. One of the strategies offered to the presentist consists in relativizing existence to inertial (...) frames. This unfashionable strategy has been accused of counterfeiting, since the meaning of the concept of existence would be incompatible with its relativization. Therefore, existence could only be relativistically invariant. In this paper, I shall examine whether such an accusation hits its target, and I will do this by examining whether the different criteria of existence that have been suggested by the Philosophical Tradition from Plato onwards imply that existence cannot be relativized.

An important divide in the free will literature—one that is arguably almost as common as the distinction between compatibilism and incompatibilism—concerns the distinction between event and substance causation. As the story typically goes, event-causalists maintain that an action is free only if it is caused by appropriate mental events, and agent-causalists maintain that an action is free only if it is caused directly by a substance (the agent). This paper argues that this dichotomy is a false one. It does this (...) by introducing a new view called Causal Pluralism, which maintains that free will is compatible with both event and substance causation. Furthermore, it is argued that agent-causalists have good reason to adopt Causal Pluralism, and also that that the view has interesting implications for the free will dialectic. (shrink)

I ask whether figure-ground structure can be realized in touch, and, if so, how. Drawing on the taxonomy of touch sketched in Katz's 1925 The World of Touch, I argue that the form of touch that is relevant to such consideration is a species of immersed touch. I consider whether we can feel the space we are immersed in and, more specifically, the empty space against which the surfaces of objects, as I shall urge, “stand out.” Harnessing M. G. F. (...) Martin's account of bodily awareness and touch, I defend a positive thesis, pace Graham Nerlich on whose The Shape of Space I otherwise rely, both to defend the supposition that empty space can in principle be felt and to argue that touching empty space is not a mere species of absence perception. Along the way, I defuse a causal worry that might be thought to arise in the case of touching empty space. (shrink)

The Hole Argument is primarily about the meaning of general covariance in general relativity. As such it raises many deep issues about identity in mathematics and physics, the ontology of space–time, and how scientific representation works. This paper is about the application of a new foundational programme in mathematics, namely homotopy type theory, to the Hole Argument. It is argued that the framework of HoTT provides a natural resolution of the Hole Argument. The role of the Univalence Axiom in the (...) treatment of the Hole Argument in HoTT is clarified.

Open future is incompatible with realism about possible worlds. Since realistically conceived (concrete or abstract) possible worlds are maximal in the sense that they contain/represent the full history of a possible spacetime, past and future included, if such a world is actual now, the future is fully settled now, which rules out openness. The kind of metaphysical indeterminacy required for open future is incompatible with the kind of maximality which is built into the concept of possible worlds. The paper discusses (...) various modal realist responses and argues that they provide ersatz openness only, or they lead to incoherence, or they render the resulting theory inadequate as a theory of modality. The paper also considers various accounts of the open future, including rejection of bivalence, supervaluationism, and the ‘thin red line’ view (TRL), and claims that a version of (TRL) can avoid the incompatibility problem, but only at the cost of deflating the notion of openness.
