Information and Communication Technologies, ICTs, has now for decades being increasingly taken into use for higher education, enabling distance learning, e-learning and online learning, mainly in parallel to mainstream educational practise. The concept Blended learning (BL) aims at the integration of ICTs with these existing educational practices. The term is frequently used, but there is no agreed-upon definition. The general aim of this dissertation is to identify new possible perspectives on ICTs and access to higher education, for negotiating the dichotomy (...) between campus-based and ICT-enabled education. The access options of BL are in focus for this dissertation, although BL is generally seen as a campus phenomenon, and shares a place perspective. The main research questions in the dissertation are 1) how BL can be understood in the context of increased access to education, moreover, (2) how time can be work as a more constructive perspective for designing ICTs in education, compared to place. The dissertation comprises five articles. The first is conceptual and concentrates on place and time in blended learning, and forms a time-based model and perspective, drawing on the tension between synchronous and asynchronous modalities instead of a place-based center-periphery model. The following article examines the differences between North American and European use of the term BL, in education and research, and finds that BL is not much used by European researchers, although the term is frequently used in educational environments. Two design and intervention studies, articles 3 and 4, make experiments using the BL time-based model. In article 3, a group of untraditional learners at a learning centre in Arvidsjaur attends a synchronous co-located study circle group and participates in an asynchronous and global Massive Open Online Course (MOOC). In article 4, nine students in a preparatory year for entering engineering studies volunteer and participate in a pilot distance course experiment, where prevention of procrastination is a high priority. For this, agile framework theory, constructivist learning theory and the time-based model are used in design and analysis. The last article (5) reconnects learning to place by discussing and adapting Triple- and Quadruple Helix theory for regional development in the knowledge society to four regional European cases. At the end of the synthesis, an outline of the access affordances with the time-based model is given, drawing on Adam’s timescape theory. The discussion of ICT integration into education is made drawing on Floridi’s Philosophy of Information, which provides many tools to view discourses of ICTs in education critically, and also envisions the concept of e-ducation in the infosphere, where other blend issues appear connected to weak artificial intelligence and the pervasive power of ICTs.

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)

The A-theory and the B-theory advance competing claims about how time is grounded. The A-theory says that A-facts are more fundamental in grounding time than are B-facts, and the B-theory says the reverse. We argue that whichever theory is true of the actual world is also true of all possible worlds containing time. We do this by arguing that time is uniquely groundable: however time is actually grounded, it is necessarily grounded in that way. It follows that if either the (...) A-theory or the B-theory is actually false, then it is necessarily false. (shrink)

This paper elaborates on relationalism about space and time as motivated by a minimalist ontology of the physical world: there are only matter points that are individuated by the distance relations among them, with these relations changing. We assess two strategies to combine this ontology with physics, using classical mechanics as example: the Humean strategy adopts the standard, non-relationalist physical theories as they stand and interprets their formal apparatus as the means of bookkeeping of the change of the distance relations (...) instead of committing us to additional elements of the ontology. The alternative theory strategy seeks to combine the relationalist ontology with a relationalist physical theory that reproduces the predictions of the standard theory in the domain where these are empirically tested. We show that, as things stand, this strategy cannot be accomplished without compromising a minimalist relationalist ontology. (shrink)

The paper will explore a key tension between eternity and temporality that comes to the fore in the seeming contradiction between freedom of the human will and divine foreknowledge of future contingents. It will be claimed that Duns Scotus’s adaptation of Thomas Aquinas’s view reduces the tension between a human being’s freedom and divine foreknowledge of future contingents to the question of how to conflate the now of eternity and our experience of the instantaneous now. Scotus’s account of the matter (...) is unfortunately not satisfying and it is the purpose of this paper to develop this insight further in a speculative manner. In order to make such co-nowness possible, it will be asked how the eternal and the temporal can co-cause together. This problem will be tackled through a development of Scotus’s doctrine of the will taken elsewhere, in order to examine how the divine and the human wills can occur together. It will be claimed that such co-willing produces a co-nowness of the eternal and the instantaneous ‘nows’ which generates a logical temporal movement. (shrink)

Arguing first that the best way to understand what a continuant is is as something that primarily has its properties at a time rather than atemporally, the paper then defends the idea that there are occurrent continuants. These are things that were, are, or will be happening—like the ongoing process of someone reading or my writing this paper, for instance. A recently popular philosophical view of process is as something that is referred to with mass nouns and not count nouns. (...) This has mistakenly encouraged the view that the only way to think of process is as the stuff of events, and has obscured the possibility of thinking of processes as individual continuants. (shrink)

Hegel famously criticizes Kant’s resolution of the antinomies. According to Sedgwick, Hegel primarily chastises Kant’s resolution for presupposing that concepts are ‘one-sided’, rather than identical to their opposites. If Kant had accepted the dialectical nature of concepts, then (according to Sedgwick) Kant would not have needed to resolve the antinomies. However, as Ameriks has noted, any such interpretation faces a serious challenge. Namely, Kant’s first antinomy concerns the universe’s physical dimensions. Even if we grant that the concept of the finite (...) is necessarily related to that of the infinite, the physical universe cannot both have and lack a temporal beginning. I argue that Hegel neither adopts Sedgwick’s view that Kant’s antinomies require no resolution nor absurdly accepts that the physical universe both has and lacks a temporal beginning. Instead, Hegel proposes a sophisticated resolution of Kant’s first antinomy (including its physical aspect) that depends on Hegel’s theory of the Absolute. (shrink)

The experience of temporal flow is, for many, the central—if not the only—reason for believing an A-theory of time. Recently, however, B-theorists have argued that experience does not, in fact, favor the A-theory. Call such an argument: a debunking argument. The goal of the present paper is to defend the A-theory against two prominent versions of the debunking argument.

Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...) past, present, and future are all equally real and there is nothing metaphysically special about the present. A third is perdurantism, according to which persisting material objects are made up of different temporal parts located at different times. We sketch routes from relativity to unitism and to the B-theory. We then discuss some routes to perdurantism, via the B-theory and via unitism. (shrink)

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

This introductory chapter reviews research on future-oriented mental time travel to date (the past), provides an overview of the contents of the book (the present), and enumerates some possible research directions suggested by the latter (the future).

In this article I discuss the seeming contingency of the fact that one is the specific person that one is. Here, I propose that this contingency is illusory.

There are two types of theories regarding many worlds: one is modal, while the other is temporal. The former regards reality as consisting of many possible worlds, while the latter holds that reality consists of many momentary worlds, which are usually called moments. I compare these two theories, paying close attention to the concept of transworld identity and compare trans-possible world identity with trans-momentary world identity (or transmoment identity). I characterize time from the point of many-worlds view, believing this to (...) be one of the best ways of grasping the reality of time. First, I show that there is reason to adopt the many-worlds view because transworld identity is meaningful for both of them, while it is not for space. Second, I argue that transmoment identity is different from transpossible world identity concerning reality. The former is a realistic relation, while the latter is not. Thus, I find that the reality of time is in the relation of transmoment identity. Such a view, I contend, has merit on the basis that it recognizes the reality of time in a sense that is not true of space. (shrink)

The article discusses the relation between two intuitive properties of time, namely its flow and branching. Both properties are introduced first in an informal way and compared. The conclusion of this informal analysis is that the two properties do not entail each other nor are they in contradiction. In order to verify this, we briefly introduced the branching temporal structures called branching space-time, branching continuation and their versions Minkowski branching structure and branching time with Instants. Two possible ways how to (...) formalize flow of time are given, one based on the definition of flow of time from temporal logics and the other based on relativistic physics. The latter is used to define flow of time with the use of linearly ordered points on worldines while respecting the ontological definiteness given by the difference of the past and the future. This is formalized in each of the branching models and it is concluded by comparing the resulting properties that branching and flow, even in the formal sense, do not entail each other. However, notions connected with flow of time represent a useful basis for semantics of the branching models. (shrink)

Languages involving modalities and languages involving vagueness have each been thoroughly studied. On the other hand, virtually nothing has been said about the interaction of modality and vagueness. This paper aims to start filling that gap. Section 1 is a discussion of various possible sources of vague modality. Section 2 puts forward a model theory for a quantified language with operators for modality and vagueness. The model theory is followed by a discussion of the resulting logic. In Section 3, the (...) framework will permit us to address a puzzle raised by Elizabeth Barnes and Robert Williams. (shrink)

In General Relativity in Hamiltonian form, change has seemed to be missing, defined only asymptotically, or otherwise obscured at best, because the Hamiltonian is a sum of first-class constraints and a boundary term and thus supposedly generates gauge transformations. Attention to the gauge generator G of Rosenfeld, Anderson, Bergmann, Castellani et al., a specially _tuned sum_ of first-class constraints, facilitates seeing that a solitary first-class constraint in fact generates not a gauge transformation, but a bad physical change in electromagnetism or (...) General Relativity. The change spoils the Lagrangian constraints, Gauss's law or the Gauss-Codazzi relations describing embedding of space into space-time, in terms of the physically relevant velocities rather than auxiliary canonical momenta. But the resemblance between the gauge generator G and the Hamiltonian H leaves still unclear where objective change is in GR. Insistence on Hamiltonian-Lagrangian equivalence, a theme emphasized by Castellani, Sugano, Pons, Salisbury, Shepley and Sundermeyer among others, holds the key. Taking objective change to be ineliminable time dependence, one recalls that there is change in vacuum GR just in case there is no time-like vector field xi^a satisfying Killing's equation L_xi g_mn=0, because then there exists no coordinate system such that everything is independent of time. Throwing away the spatial dependence of GR for convenience, one finds explicitly that the time evolution from Hamilton's equations is real change just when there is no time-like Killing vector. The inclusion of a massive scalar field is simple. No obstruction is expected in including spatial dependence and coupling more general matter fields. Hence change is real and local even in the Hamiltonian formalism. The considerations here resolve the Earman-Maudlin standoff over change in Hamiltonian General Relativity: the Hamiltonian formalism is helpful, and, suitably reformed, it does not have absurd consequences for change and observables. Hence the classical problem of time is resolved. The Lagrangian-equivalent Hamiltonian analysis of change in General Relativity is compared to Belot and Earman's treatment. The more serious quantum problem of time, however, is not automatically resolved due to issues of quantum constraint imposition. (shrink)

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

Since J. McTaggart’s paper on “The Unreality of Time” the opposition of “A-theorists” and “B-theorists” establishes a focal point in the modern debate on the metaphysics of time: While “A-theorists” claim the existence of an objective present, moving along time positions, “B-theorists” maintain that time is just a set of ontologically equivalent coordinates, “now” being merely the indexical of the speaker’s position. Contemporary attempts to resolve the issue by resorting to the analysis of language or to the theory of science (...) seem to deliver no definite results. By contrast, practical and existential aspects of the two models promise to be more univocal guides in deciding between them. Particularly, C. D. Broad’s hybrid conception of a “growing block theory” attains special attractiveness in this regard. (shrink)

The text is divided into two parts. In the first part, the author describes the eternalists’ and presentists’ positions as the two basic possible statements of the ontology of time . The eternalist position and the emphasis it puts on the actual existence of past and future events are thoroughlly analysed in order to show that in fact, they end up making strings of symbols that are not correct statements. It is therefore necessary to step beyond these clumsy statements and (...) try to understand more exactly the eternalist intuitions on a deeper, metaphysical level. That is the main concern of the second part of the text, in which the metaphysical implications of both positions are compared. At the end of the linguistical analysis in the first part, we got to a point where it may seem that presentism and eternalism are only different attempts at expressing what is in fact the same understanding of the nature of time, but in the metaphysical analysis that follows, it will turn out that they are not. Presentism and eternalism are shown to be two different ontological approaches of time in relation to space . The author then focuses on the consequences these two positions have especially on the concept of the present and of its flow through time. In the end, presentism and eternalism turn out to be completely different positions that – in parallel with the famous McTaggart’s argument – claim a very strong reality of time on the one hand or, on the other hand, its utter unreality.

The Stoics offer us a very puzzling conception of causation and an equally puzzling ontology. The aim of the present paper is to show that these two elements of their system elucidate each other. The Stoic conception of causation, I contend, holds the key to understanding the ontological category of incorporeals and thus Stoic ontology as a whole, and it can in turn only be understood in the light of this connection to ontology. The thesis I defend is that the (...) Stoic incorporeals are to be understood as effects, as effects of the causality of bodies. What is gained by this thesis? First, it explains how the seemingly heterogeneous item of ‘sayables’ (lekta) fits into the category of incorporeals. Second, it allows for a new interpretation of the two verbs with which the Stoics characterize the way of being of incorporeals, huphistanai and huparchein. And, third, it sheds light on the peculiar features of the Stoic conception of causation. (shrink)

This article defends Marjorie Suchocki’s position against two main objections raised by David E. Conner. Conner objects that God as a single actual entity must be temporal because there is succession in God’s experience ofthe world. The reply is that time involves at least two successive occasions separated by perishing, but in God nothing ever perishes. Conner also objects that Suchocki’s personalistic process theism is not experiential but is instead theoretical and not definitive. The reply is that his dismissal of (...) Part V of PR is arbitrary, the interpretation of all experience is theoretical, and no metaphysical interpretations are absolutely definitive, including PR as a whole. Also, Conner ignores religious experience. (shrink)

There are two intuitions about time. The first is that there's something special about the present that objectively differentiates it from the past and the future. Call this intuition Specialness. The second is that the time at which we happen to live is just one among many other times, all of which are ‘on a par’ when it comes to their forming part of reality. Call this other intuition Egalitarianism. Tradition has it that the so-called ‘A-theories of time’ fare well (...) at addressing the first intuition, but rather badly when it comes to the second. The goal of this article is to offer advice to A-theorists about how to reconcile their view with Egalitarianism. (shrink)

Does mere passage of time have causal powers ? Are properties like "being n days past" causally efficient ? A pervasive intuition among metaphysicians seems to be that they don't. Events and/or objects change, and they cause or are caused by other events and/or objects; but one does not see how just the mere passage of time could cause any difference in the world. In this paper, I shall discuss a case where it seems that mere passage of time does (...) have causal powers : Sydney Shoemaker's (1969) possible world where temporal vacua (allegedly) take place. I shall argue that Shoemaker's thought-experiment doesn't really aim at teaching us that there can be time without change, but rather that if such a scenario is plausible at all (as I think it is) it provides us with good reasons to think that mere passage of time can be directly causally efficient.

What someone’s behaviour must be like if we are to be aware of their emotions in it Content Type Journal Article Pages 1-14 DOI 10.1007/s11097-011-9224-0 Authors Rowland Stout, School of Philosophy, UCD Dublin, Dublin 4, Republic of Ireland Journal Phenomenology and the Cognitive Sciences Online ISSN 1572-8676 Print ISSN 1568-7759.

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?

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 thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we accept the B-theory, the commonsensical ‘endurance theory’ of persistence will have to be rejected. The endurance theory says (...) that objects persist through time by being wholly present at distinct times as numerically the same entity. Instead of endurantism, it has been argued, we have to adopt either ‘perdurantism’ or the ‘stage theory’. Perdurantism is the theory that objects are four-dimensional ‘space-time worms’ persisting through time by having distinct temporal parts at distinct times. The stage theory says that objects are instantaneous temporal parts (stages) of space-time worms, persisting by having distinct temporal counterparts at distinct times. In the thesis, it is argued that no good arguments have been provided for the conclusion that we are obliged to drop the endurance theory by acceptance of the B-theory. This conclusion stands even if the endurance theory incorporates the claim that objects endure through intrinsic change. It is also shown that perdurantism and the stage theory come with unwelcome consequences. -/- Paper I demonstrates that the main arguments for the view that objects cannot endure in B-time intrinsically unchanged fail. Papers II and III do the same with respect to the traditional arguments against endurance through intrinsic change in B-time. Paper III also contains a detailed account of the semantics of the tenseless copula, which occurs frequently in the debate. The contention of Paper IV is that four-dimensional space-time worms, as traditionally understood, are not suited to take dispositional predicates. In Paper V, it is shown that the stage theory needs to introduce an overabundance of persistence-concepts, many of which will have to be simultaneously applicable to a single object (qua falling under a single sortal), in order for the theory to be consistent. The final article, Paper VI, investigates the sense in which persistence can, as is sometimes suggested, be a ‘conventional matter’. It also asks whether alleged cases of ‘conventional persistence’ create trouble for the endurance theory. It is argued that conventions can only enter at a trivial semantic level, and that the endurance theory is no more threatened by such conventions than are its rivals. (shrink)

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

The apparent 'flow' of time is one of its most mysterious features, and one which discomforts both scientists and philosophers. One of the most striking assaults upon it is McTaggart's argument that the idea of temporal flow is demonstratively incoherent. In this paper I first urge that the idea of temporal flow is an important part of our intuitive understanding of time, underpinning several of our notions about rationality and time. Second, I try to undercut McTaggart's argument by showing that (...) it is not temporal flow which is illusory but rather the vicious regress McTaggart saw in that idea. A steadfast clinging to the notion of now, along with an analysis of McTaggart's argument reveals that the regress halts after but two steps. (shrink)

The concept of temporal flow has been attacked both on the grounds that it is logically incoherent, and on the grounds that it conflicts with the theory of relativity. I argue that the charge of incoherence cannot be made to stick: McTaggart's argument commits the fallacy of equivocation, and arguments deployed by Smart and others turn out to be question-begging. But objections arising from relativity, so I claim, have considerably more force than Lucas acknowledges. Moreover, the idea of equating the (...) cosmic time which arises in general relativistic cosmology with a metaphysically preferred space-time foliation, founders on the fact that the Friedmann models are idealisations. Finally, Lucas may be right in claiming that dynamical wave-function collapse, provided it does not propagate superluminally, will define a preferred foliation. But it is arguable that this consideration, so far from supporting Lucas's position, is grounds for rejecting collapse interpretations of quantum mechanics. (shrink)

It is, I think, possible to generate a variation of McTaggart’s (Mind 17:457–474, 1908 ) paradox that infects all extant versions of presentism. This is not to say that presentism is doomed to failure. There may be ways to modify presentism and I can’t anticipate all such modifications, here. For the purposes of the paper I’ll understand ‘presentism’ to be the view that for all x , x is present (cf. Crisp ( 2004 : 18)). It seems only right that, (...) at a conference devoted to McTaggart’s work on time, we continue to pursue new ways in which his now infamous arguments remain relevant to us today. (shrink)

It is argued that a subject who has an experience as of succession can have this experience at a time, or over a period of time, during which there occurs in him no succession of conscious mental states at all. Various metaphysical implications of this conclusion are explored. One premise of the main argument is that every experience is an experience as of succession. This implies that we cannot understand phenomenal temporality as a relation among experiences, but only as a (...) primitive feature of experience, or else as something analyzable into wholly non-phenomenal terms.

According to a plausible and influential account of perceptual knowledge, the truth-makers of beliefs that constitute perceptual knowledge must feature in the causal explanation of how we acquire those beliefs. However, this account runs into difficulties when it tries to accommodate time perception -- specifically perception of order and duration -- since the features we are apparently tracking in such perception are not causal. The central aim of the paper is to solve this epistemological puzzle. Two strategies are examined. The (...) first strategy locates the causal truth-makers within the psychological mechanism underlying time perception, thus treating facts about time order and duration as mind-dependent. This strategy, however, is problematic. The second strategy modifies the causal account of perceptual knowledge to include a non-causal component in the explanation of belief-acquisition, namely chronometric explanation. Applying this much more satisfactory approach to perceptual knowledge of time, we can preserve the mind-independence of order and duration, but not that of time's flow. (shrink)

Rabbi Nachman of Bratslav describes the tzaddik as experiencing time in a distinctive, enlightened way: What is seventy years for the rest of us feels like a mere fifteen minutes for the tzaddik. Furthermore, even higher levels of enlightenment are possible—for a tzaddik on a higher level, what feels like seventy years for the first tzaddik is again but a mere fifteen minutes. This pattern continues, approaching a limit point which Rabbi Nachman calls “above time,” and which is the perspective (...) on time of the Divine. How might Rabbi Nachman’s claims about enlightened temporal experience be understood? In this paper, my aim is to examine some ways of understanding what it might mean to ‘experience time more quickly’ or to ‘experience 70 years as 15 minutes’ in light of contemporary theories of the structure of temporal experience. I then present a novel interpretation of Rabbi Nachman’s claims which appeals to the contemporary notion of the specious present —a nonzero temporal interval experienced in a unified way as present.

In this paper, we propose a mathematical model of subjective experience in terms of classes of hierarchical geometries of representations (“n-awareness”). We first outline a general framework by recalling concepts from higher category theory, homotopy theory, and the theory of (infinity,1)-topoi. We then state three conjectures that enrich this framework. We first propose that the (infinity,1)-category of a geometric structure known as perfectoid diamond is an (infinity,1)-topos. In order to construct a topology on the (infinity,1)-category of diamonds we then propose (...) that topological localization, in the sense of Grothendieck-Rezk-Lurie (infinity,1)-topoi, extends to the (infinity,1)-category of diamonds. We provide a small-scale model using triangulated categories. Finally, our meta-model takes the form of Efimov K-theory of the (infinity,1)-category of perfectoid diamonds, which illustrates structural equivalences between the category of diamonds and subjective experience (i.e.its privacy, self-containedness, and self-reflexivity). Based on this, we investigate implications of the model. We posit a grammar (“n-declension”) for a novel language to express n-awareness, accompanied by a new temporal scheme (“n-time”). Our framework allows us to revisit old problems in the philosophy of time: how is change possible and what do we mean by simultaneity and coincidence? We also examine the notion of “self” within our framework. A new model of personal identity is introduced which resembles a categorical version of the “bundle theory”: selves are not substances in which properties inhere but (weakly) persistent moduli spaces in the K-theory of perfectoid diamonds.

Charles Sanders Peirce is best known as the founder of pragmatism, but the name that he preferred for his overall system of thought was ‘‘synechism’’ because the principle of continuity was its central thesis. He considered time to be the paradigmatic example and often wrote about its various aspects while discussing other topics. This essay draws from many of those widely scattered texts to formulate a distinctively Peircean philosophy of time, incorporating extensive quotations into a comprehensive and coherent synthesis. Time (...) is not an existential subject with past, present, and future as its incompatible predicates, but rather a real law enabling things to possess contrary qualities at its different determinations, and Peirce identifies four classes of such states based on when and how they are realized. Because time is continuous, it is not composed of instants, and even the present is an indefinite lapse during which we are directly aware of constant change. The accomplished past is perpetually growing as the possibilities and conditional necessities of the future are actualized at the present, and the entire universe evolves from being utterly indeterminate toward being absolutely determinate. Nevertheless, time must return into itself even if events are limited to only a portion of it, a paradox that is resolved with the aid of projective geometry. Temporal synechism thus touches on a broad spectrum of philosophical issues including mathematics, phenomenology, logic, and metaphysics. (shrink)

The debate between Einstein and Bergson is a salient episode in the history of modern physics and a telling example of the interaction between science and philosophy. This paper initially discusses five reasons why Bergson criticised Einstein for giving up absolute time. The most important one was Bergson’s commitment to an intuitionist, anti-Kantian metaphysics informed by common sense. Apart from that, he knew that the theory of special relativity permits “duration” in the form of the passage of proper time, to (...) which Bergson referred as “real time”. Neither static eternalism nor dynamic eternalism are acceptable from Bergson’s philosophical perspective, which acknowledges the role of temporal experience and everyday thinking in addition to science and metaphysics. He understood temporal passage as creation of new existence, anticipating what later became known as the growing block theory of time. The pointy relativistic variant of this theory, which divides the universe into blocks of growing past light cones, does justice to large parts of his philosophy, including the distinction between the actual and the virtual. Supporters of Bergson’s account of duration should adopt this theory of time. (shrink)

Non-reductivists about phenomenal consciousness believe that physical facts are insufficient to ground the existence of phenomenal consciousness. It will be argued that if one is going to be a non-reductivist, then one should not limit oneself to expanding one’s catalogue of the world’s basic features, as recommended in the paradigmatic non-reductivist approach developed by David Chalmers. One should rather take a realist stance towards subjectivity. A realist about subjectivity thinks that at least some of the propositions needed to state how (...) things are in reality are such that their truth-value is capable of changing ‘from one subject to another’. Realism about subjectivity will be introduced by means of an analogy with the so called ‘A-theory’ of time. An A-theorist claims that at least some of the propositions needed to state how things are in reality are such that their truth-value is capable of changing ‘from one time to another’. It turns out that a robust notion of metaphysical reality is necessary to make sense of both realism about subjectivity and the A-theories of time. (shrink)

The first part of this thesis articulates and defends the Subjectivist View of the Mental. According to this view, my mental states are essentially different from the mental states of everyone else, but the fact that they are is a subjective fact, rather than an objective one. Chapter 1 explains what it takes for a fact to be subjective, what kind of difference holds between my mental states and everyone else's mental states and what kind of intuitions lead me to (...) believe that there is such a difference. Chapter 2 defends the Subjectivist View of the Mental from objections and discusses some of its most significant implications. In the second part of the thesis, I explore the advantages that the Subjectivist View of the Mental offers when it comes to accounting for three basic features of our knowledge of the mental. Chapter 3 deals with the asymmetry between self-knowledge and knowledge of other minds. It is argued that, if the Subjectivist View of the Mental is true, we can explain why this asymmetry holds without assuming that self-knowledge and knowledge of other minds are involved with substantially different ways of knowing. Chapter 4 focuses on the immunity to error through misidentification of mental self-ascriptions. I show that, while there has been a temptation to explain this phenomenon by following Lichtenberg and Wittgenstein in taking the content of mental self-ascriptions to be general rather than particular, this proposal cannot be made to work unless something like the Subjectivist View of the Mental is true. Chapter 5 is concerned with experiential knowledge. I argue that, if experiential truths are taken to be objective truths, it is not easy to see why experiential knowledge should have the peculiar 'first-hand' character it has. The problem disappears if experiential truths are regarded as subjective rather than objective. (shrink)

This paper discusses the problem of inconsistencies in the metaphorical conceptualizations of time that involve motion within the framework of conceptual metaphor theory (CMT). It demonstrates that the TIME AS A PURSUER metaphor contrasts with the reverse variant TIME AS AN OBJECT OF PURSUIT, just as the MOVING TIME metaphor contrasts with the MOVING OBSERVER variant. Such metaphorical conceptualizations of time functioning as pairs of minimally differing variants based on Figure-Ground reversal are, strictly speaking, inconsistent with one another. Looking at (...) these inconsistencies from a wider perspective suggests that time may belong to a separate category of conceptual phenomena. This paper puts forward a proposal to approach time from the perspective of “phenomena of the third kind”, which according to Keller’s thesis include conceptual establishments resulting from human cognition, but not of human design.
