The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow arises due to the second law of thermodynamics. In this paper, we investigate the epistemic arrow of time using a fully formal framework. We begin by defining a memory system (...) as any physical system whose present state can provide information about the state of the external world at some time other than the present. We then identify two types of memory systems in our universe, along with an important special case of the first type, which we distinguish as a third type of memory system. We show that two of these types of memory systems are time-symmetric, able to provide knowledge about both the past and the future. However, the third type of memory systems exploits the second law of thermodynamics, at least in all of its instances in our universe that we are aware of. The result is that in our universe, this type of memory system only ever provides information about the past. We also argue that human memory is of this third type, completing the argument. We end by scrutinizing the basis of the second law itself. This uncovers a previously unappreciated formal problem for common arguments that try to derive the second law from the “Past Hypothesis”, i.e., from the claim that the very early universe was in a state of extremely low entropy. Our analysis is indebted to prior work by one of us but expands and improves upon this work in several respects. (shrink)

Research on an expert system regarding unemployment insurance law has pointed to the difficulties of explicitly representing temporal relations. The question has been addressed in the artificial intelligence literature with respect to planning systems and linguistic analysis. The approaches adopted do not appear to be directly transposable to legal discourse. The problem seems so far to have escaped notice amongst researchers attempting to develop legal expert systems. The paper explores in a preliminary way how lawyers use temporal concepts. It is (...) submitted that “legal time” only partly overlaps with real time. A sketch of a formalization of temporal relations in law, following J. F. Allen's approach, is presented. (shrink)

The Great Divide in metaphysical debates about laws of nature is between Humeans, who think that laws merely describe the distribution of matter, and non-Humeans, who think that laws govern it. The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental direction (...) of time in the universe. In this paper, we propose a minimal primitivism about laws of nature (MinP) according to which there is no such requirement. On our view, laws govern by constraining the physical possibilities. Our view captures the essence of the governing view without taking on extraneous commitments about the direction of time or dynamic production. Moreover, as a version of primitivism, our view requires no reduction / analysis of laws in terms of universals, powers, or dispositions. Our view accommodates several potential candidates for fundamental laws, including the principle of least action, the Past Hypothesis, the Einstein equation of general relativity, and even controversial examples found in the Wheeler-Feynman theory of electrodynamics and retrocausal theories of quantum mechanics. By understanding governing as constraining, non-Humeans who accept MinP have the same freedom to contemplate a wide variety of candidate fundamental laws as Humeans do. (shrink)

This paper investigates what the source of time asymmetry is in thermodynamics, and comments on the question whether a time-symmetric formulation of the Second Law is possible.

Ryan Wasserman explores a range of fascinating puzzles raised by the possibility of time travel, with entertaining examples from physics, science fiction, and popular culture, and he draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, laws of nature, persistence, change, and mereology.

The authors consider the legal and ethical considerations of offering a time-limited trial of a potentially non-beneficial intervention in the setting of patient or surrogate requests to pursue aggressive treatment. The likelihood of an intervention’s success is rarely a zero-sum game, and an intervention’s risk-to-benefit ratio may be indiscernible without further information (often, a matter of time).

. A structured awareness of time lies at the core of the law's distinctive normativity. Melody is offered as a rough model of this mindfulness of time, since some important features of this awareness are also present in a hearer's grasp of melody. The model of melody is used, first, to identify some temporal dimensions of intentional action and then to highlight law's mindfulness of time. Its role in the structure of legal thinking, and especially in precedent‐sensitive (...) legal reasoning, is explored. This article argues further that melody‐modeled mindfulness of time is evident also at a deeper and more pervasive level, giving structure to the distinctive mode of law's normative guidance. The article draws one important theoretical consequence from this exploration, namely, that the normative coherence of momentary legal systems depends conceptually on their coherence over time.

The promised paradises of colonial capitalism and neoliberalism are set in a perpetually elusive future (Fitzpatrick 1992). This future is not a set destination, but an endless linear journey set to the thrum of ‘progress’ and ‘development’. This paper considers, in the context of recent cases relating to development in the Athabasca tar sands region, what the law of the Canadian settler state does when it is faced with interruptions and ruptures in its timescape. Drawing on Fitzpatrick’s seminal work, The (...) Mythology of Modern Law, I argue that a conceptualisation of law’s behaviour in these contexts as functionally mythological highlights some of the elusive ways that settler law maintains a stranglehold over legal imaginaries of oil and gas developments: by distorting and flattening the pasts and presents of Indigenous societies that pre-dated (and continue to co-exist with) the settler state on ‘Canadian’ land, by mediating between the ‘origin’ of the settler state and the daily rhythms of colonial time through ‘Eternal Objects’ such as property and economic development, and by asserting a general ‘objectivity’ of law to evade any direct grappling with the stark possibilities of the ‘end of the world’ created by the climate crisis. I conclude, drawing on Indigenous scholarship and the work of de Goede and Randalls, that a meaningful response to the climate crisis requires re-enchanted attachments to life that necessitate a departure from the one-dimensional temporality of the mythologies of settler law.

The inductive problem of extending the sequence 1, 3, 5, 7, is solved when these numbers are the ratios of the incremental distances fallen in successive unit times. The controlling fact is Galileo’s assumption that these ratios are invariant under a change of the unit of time. It admits few laws and only one is compatible with the two-numbered initial sequence 1, 3.

This Article shows how three modern English thinkers — Hobbes, Locke and Bentham — construe the law as an intersection of secular eternity on the one one hand and transience in modernity on the other, allowing for immovability and movement at the same time, combining stability with change. It details how these theorists, who undoubtedly have earned themselves places of honor in the canon of modern political thought, tried to solve the problem of self-grounding in three different and yet (...) paradigmatically modern ways, each of them intertwining law and time in a different fashion, and each of them connecting both law and temporality to happiness. Thus this Article shows not only that these three British thinkers claim in one way or another that while natural desires may provide pleasure, only the law can bring happiness, but also emphasizes that, in their view, the transformation of the former into the latter entails a transformation of temporal consciousness. Thereby this Article foregrounds two elements that are crucial to an understanding of how seventeenth and eighteenth century British thinkers envisaged the transformation of pleasure into happiness by means of the law: first, the notion that the law creates or reinforces duration in social life, and second, the idea that the law can harness the immediacy of desires by assuring the legal protection of enduring pleasures, which lead to happiness.

The Spirit of the Laws is, without question, one of the central texts in the history of eighteenth-century thought, yet there has been no complete, scholarly English-language edition since that of Thomas Nugent, published in 1750. This lucid translation renders Montesquieu's problematic text newly accessible to a fresh generation of students, helping them to understand quite why Montesquieu was such an important figure in the early enlightenment and why The Spirit of the Laws was, for example, such an influence upon (...) those who framed the American constitution. Fully annotated, this edition focuses attention upon Montesquieu's use of sources and his text as a whole, rather than upon those opening passages towards which critical energies have traditionally been devoted, and a select bibliography and chronology are provided for those coming to Montesquieu's work for the first time.

The medical profession consistently strives to uphold patient empowerment, equality and safety. It is ironic that now, at a time where advances in technology and knowledge have given us an increased capacity to preserve and prolong life, we find ourselves increasingly asking questions about the value of the lives we are saving. A recent editorial by Professor Raanan Gillon questions the emphasis that English law places on the sanctity of life doctrine. In what was described by Reverend Nick Donnelly (...) as a “manifesto for killing patients”, Professor Gillon argues that the sanctity of life law has gone too far because of its disregard for distributive justice and an incompetent person’s previously declared autonomy. This review begins by outlining the stance of the sanctity of life doctrine on decisions about administering, withholding and withdrawing life-prolonging treatment. Using this as a foundation for a rebuttal, a proposal is made that Professor Gillon’s assertions do not take the following into account. (shrink)

It seems that time has direction which points ahead from the past to the future. Traditionally, the main efforts to explain the arrow of time were carried out within the domain of physics, primarily utilizing statistical mechanics laws. Here, I attempt to explain how the forward direction of time is configured from the viewpoint of the mind. At first impression the concept of forward direction stems from the meeting of subjectivity with space and as such it is (...) applied to time. However, I show that the forward direction of time has a unique temporal sense not derived from space. Later I relate phenomenological explanations of the flow of time to the direction of time.

The arrow of time is a familiar phenomenon we all know from our experience: we remember the past but not the future and control the future but not the past. However, it takes an effort to keep records of the past, and to affect the future. For example, it would take an immense effort to unmix coffee and milk, although we easily mix them. Such time directed phenomena are sub- sumed under the Second Law of Thermodynamics. This law (...) characterizes our experience of the arrow of time in terms of an increase of a theoretical magnitude called entropy. Statistical mechan- ics tries to explain the Second Law as an effect of the behavior of the microscopic particles that make up the universe. Since our senses are too coarse to see this microstructure, statistical mechanics describes our experience in terms of probability, or in terms of the partial information we have about the particles. In this paper we explain the workings of statistical mechanics; how it accounts for probability as an objective feature of the world based on the underlying dynamics; how it accounts for our memories of the past; how the statistical mechanical probability under- writes the Second Law; and how, at the same time, it leads to a violation of the Second Law by the so-called Maxwell’s Demon.

Despite the long history of beliefs about the therapeutic properties of work for people with mental ill health, rarely has therapeutic work itself been a focus for historical analysis. In this article, the development of a therapeutic work ethic (1813—1979) is presented, drawing particular attention to the changing character and quality of beliefs about therapeutic work throughout time. From hospital factories to radical ‘antipsychiatric’ communities, the article reveals the myriad forms of activities that have variously been considered fit work (...) for people with mental health problems. While popular stereotypes of basket-weaving paint a hapless portrait of institutional work, a more nuanced reading of therapeutic work and its political and philosophical commitments is advanced. The article concludes by arguing that the non-linear and inherently contested development of therapeutic work is less the effect of paradigmatic shifts within the therapeutic professions, but rather evidence of a broader human struggle with work.

Well known quantum and time paradoxes, and the difficulty to derive the second law of thermodynamics, are proposed to be the result of our historically grown paradigm for energy: it is just there, the capacity to do work, not directly related to change. When the asymmetric nature of energy is considered, as well as the involvement of energy turnover in any change, so that energy can be understood as fundamentally "dynamic", and time-oriented, these paradoxes and problems dissolve. The (...) most basic consequence concerns the particle-wave dualism. For a reversible inter-conversion of a particle into a wave, subject to a dynamic energy, a self-image of information has to be generated: quantum theory has to be complemented by a theory of information. Then, quantum processes can be derived from classical ones and the second law of thermodynamics with the tendency of increasing entropy follows in a straightforward way. (shrink)

Pauline Kleingeld’s “Contradiction and Kant’s Formula of Universal Law”, published in this journal in 2017, presents a powerful challenge to what has become the standard reconstruction of the categorical imperative. In this response to Kleingeld, I argue that she is right to emphasise the ‘simultaneity requirement’ - that we must be able to will a proposed maxim and ‘simulataneously’, ‘also’ or ‘at the same time’ the maxim in its universalised form - but I deny that this removes the categorical (...) imperative test from the world of universalisation because the agent must be understood as part of that world. There are two distinct types of conflict: a contradiction that results from non-universalisability and Kleingeld’s ‘volitional’ conflict, located within the will of the immoral agent. The standard ‘practical’ reconstruction of the categorical imperative remains largely intact. (shrink)

In his clear-sighted, humane, and provocative way, Richard Falk calls for a revolution in thinking about the future of world order. Explorations at the Edge of Time develops the idea that a major cultural shift from modernism to postmodernism is under way, creating both new difficulties and new opportunities in the domain of global public policy. The author observes, "A postmodem possibility implies the human capacity to transcend the violence, poverty, ecological decay, oppression, injustice, and secularism of the modern (...) world." Recognizing that the concepts of "progress" and "development" have changed due to the breakdown of the modernist consensus, Falk contends that most problems have transnational dimensions. He proposes a commitment to grassroots globalism, and he challenges aspiring "citizen pilgrims" to think and act in ways that will enhance their feeling of identity with the rest of creation. Falk's "rooted utopianism" challenges our political imagination in relation to pressing global problems and helps forge an overall vision of the future. What is at stake is the building of political understanding amidst the appreciation of unity and diversity for a hopeful entry upon the 21st Century. Author note: Richard Falk is Albert G. Milbank Professor of International Law and Practice at Princeton University. He has published more than twenty books, including The Promise of World Order (Temple). (shrink)

Time flows. This oft-lamented fact of human existence seems plain enough, but is remarkably difficult to explain scientifically. Physical theory follows a greater goal—symmetry—and the directional nature of time is left adrift. The phenomenon must nevertheless be explained.Scientists since Isaac Newton have searched classical mechanics for answers, but precious little progress has been made on his mystical ideas. The discoveries of thermodynamics, though clearly relevant, have posed more problems than they have solved.Now a new solution presents itself through (...) quantum mechanics. The intimate relation between thermodynamics and time is not in doubt, but now quantum theory is explaining how the laws of entropy arise from a stranger reality. The theory of decoherence begins to explain time as a holistic quantum concept. (shrink)

The so-called Principle of Plenitude was ascribed to Leibniz by A. O. Lovejoy in The Great Chain of Being: A Study of the History of an Idea. Its temporal version states that what holds always, holds necessarily. This temporal formulation is the subject of the current paper. Lovejoy’s idea was criticised by Hintikka. The latter supported his criticisms by referring to specific Leibnizian notions of absolute and hypothetical necessities interpreted in a possible-worlds semantics. In the paper, Hintikka’s interpretative suggestions are (...) developed and enriched with a temporal component that is present in the characteristics of the real world given by Leibniz. We use in our approach the Leibnizian idea that change is primary to time and the idea that there are possible laws that characterize worlds other than the real one. We formulate a modal propositional logic with three primitive operators for change, temporal constancy, and possible lawlikeness. We give its axiomatics and show that our logic is complete with respect to the given semantics of possible worlds. Finally, we show that the counterparts of the considered versions of the Principle of Plenitude are falsified in this semantics and the same applies to the counterpart of Leibnizian necessarianism.

Recent work in both the theory of the firm and of corporate law has called into question the appropriateness of analysing corporate law as ‘merely’ a set of standard form contracts. This article develops these ideas by focusing on property law's role in underpinning corporate enterprise. Rights to control assets are a significant mechanism of governance in the firm. However, their use in this way predicates some arrangement for stipulating which parties will have control under which circumstances. It is argued (...) that ‘property rules’—a category whose scope is determined functionally—protect the entitlements of parties to such sharing arrangements against each other's opportunistic attempts to grant conflicting entitlements to third parties. At the same time, the legal system uses a range of strategies to minimize the costs such protection imposes on third parties. The choice of strategy significantly affects co-owners’ freedom to customize their control-sharing arrangements. This theory is applied to give an account of the ‘proprietary foundations’ of corporate law, which has significant implications for the way in which the subject's functions are understood and evaluated.

The aim of the article is to intervene in debates about the digital and, in particular, framings that imagine the digital in terms of epochal shifts or as redefining life. Instead, drawing on recent developments in digital methods, we explore the lively, productive and performative qualities of the digital by attending to the specificities of digital devices and how they interact, and sometimes compete, with older devices and their capacity to mobilize and materialize social and other relations. In doing so, (...) our aim is to explore the implications of digital devices and data for reassembling social science methods or what we call the social science apparatuses that assemble digital devices and data to ‘know’ the social and other relations. Building on recent work at CRESC on the social life of methods, we recommend a genealogical approach that is alive to the ways in which digital devices are simultaneously shaped by social worlds, and can in turn become agents that shape those worlds. This calls for attending to the specificities of digital devices themselves, how they are varied and composed of diverse socio-technical arrangements, and are enrolled in the creation of new knowledge spaces, institutions and actors. Rather than exploring what large-scale changes can be revealed and understood through the digital, we argue for explorations of how digital devices themselves are materially implicated in the production and performance of contemporary sociality. To that end we offer the following nine propositions about the implications of digital data and devices and argue that these demand rethinking the theoretical assumptions of social science methods: transactional actors; heterogeneity; visualization; continuous time; whole populations; granularity; expertise; mobile and mobilizing; and non-coherence.

The dependence solution claims that God’s foreknowledge is no threat to our freedom because God’s foreknowledge depends (in a relevant sense) on our actions. The assumption here is that those parts of the world which depend on our actions are no threat to the freedom of those actions. Recently, Taylor Cyr has presented a case which challenges this assumption. Moreover, since the case is analogous to the case of God’s foreknowledge, it would seem to establish that, even if God’s foreknowledge (...) somehow depends on our actions, our freedom is still threatened. This paper defends the dependence solution, first, by offering an error theory for the intuitions that drive Cyr’s case and, second, by pointing out some arguably mysterious implications of accepting those intuitions. These points taken in conjunction show that Cyr’s case, although quite fascinating, is not as challenging as it might at first seem. (shrink)

Can the second law of thermodynamics explain our mental experience of the direction of time? According to an influential approach, the past hypothesis of universal low entropy also explains how the psychological arrow comes about. We argue that although this approach has many attractive features, it cannot explain the psychological arrow after all. In particular, we show that the past hypothesis is neither necessary nor sufficient to explain the psychological arrow on the basis of current physics. We propose two (...) necessary conditions on the workings of the brain that any account of the psychological arrow of time must satisfy. And we propose a new reductive physical account of the psychological arrow of time compatible with time-symmetric physics, according to which these two conditions are also sufficient. Our proposal has some radical implications, for example, that the psychological arrow of time is fundamental, whereas the temporal direction of entropy increase in the second law of thermodynamics and the past hypothesis is derived from it, rather than the other way around. 1Introduction2A Physical Account of the Psychological Arrow of Time3Necessary Conditions for the Psychological Arrow of Time4The Psychological Arrow of Time via the Second Law of Thermodynamics and the Past Hypothesis5Why the Past Hypothesis Is Insufficient for the Psychological Arrow of Time5.1Stage 1, Version 1: From the past hypothesis to the psychological arrow via typicality5.2Stage 1, Version 2: From the past hypothesis to the psychological arrow via dynamical or causal considerations5.3Stage 2: From entropy gradient in the brain to the psychological arrow of time6Why the Past Hypothesis Is Unnecessary for the Psychological Arrow of Time7A New Reductive Account of the Psychological Arrow of Time.

At first glance, every metaphysics of laws can be combined with every ontology of time. In contrast, the paper intends to show that Humeanism requires eternalism and that Power metaphysics must presuppose an existentially dynamical view of temporal existence, i.e. growing block or presentism. The presented arguments turn out to be completely independent of whether the laws of nature are deterministic or probabilistic: the world is non-productive and static or productively dynamical, the future be ‘open’ or not.

The dominant and deceptively simple theme of this book is the relationship between the moral environment of the courtroom and that of the society in which the court is situated. Like other Past and Present conference proceedings, the volume ranges widely across time and space, from ancient Greece to twentieth-century Africa. As a consequence, it encompasses not only the highly professional legal systems of the Roman, later medieval and modern worlds, but also the relatively unprofessionalised courts of classical Athens (...) and of the early middle ages and the alien, imposed legal systems of colonial Rhodesia and Kenya. The Moral World of the Law is based upon papers delivered at the conference of that name, sponsored by the journal Past and Present and held at the University of Birmingham in 1996. (shrink)

This essay examines the theology of the nineteenth century Danish theologian and churchman Hans Lassen Martensen, focusing on the disputed question of the kenotic character of Martensen's Christology. A survey of the scholarship on this question is followed by discussions of Martensen's doctrine of God and his Christology, giving particular attention to his controversial notion of the double life of the Logos, i. e. the view that the Logos continued to enjoy an unlimited divine existence in the sphere of eternity (...) while simultaneously living a limited, earthly human existence for the duration of the incarnation. The essay concludes by arguing that Martensen has developed a form of Nestorianism and that his Christology can best be classified as ‘Nestorian kenoticism,’ i. e. an eccentric and problematic form of Christology which affirms the abandonment by the logos ensarkos of the divine attributes during the incarnation, while at the same time insisting that the logos asarkos remains unaffected and in full possession of his powers.

The Sentimental Life of International Law is about our age-old longing for a decent international society and the ways of seeing, being, and speaking that might help us achieve that aim. This book asks how international lawyers might engage in a professional practice that has become, to adapt a title of Janet Malcolm's, both difficult and impossible. It suggests that international lawyers are disabled by the governing idioms of international lawyering, and proposes that they may be re-enabled by speaking different (...) sorts of international law, or by speaking international law in different sorts of ways. In this methodologically diverse and unusually personal account, Gerry Simpson brings to the surface international law's hidden literary prose and offers a critical and redemptive account of the field. He does so in a series of chapters on international law's bathetic underpinnings, its friendly relations, the neurotic foundations of its underlying social order, its screened-off comic dispositions, its anti-method, and the life-worlds of its practitioners. Finally, the book closes with a chapter in which international law is re-envisioned through the practice of gardening. All of this is put forward as a contribution to the project of making international law, again, a compelling language for our times. (shrink)

According to Kant’s Metaphysical Foundations of Natural Science, a proper science is organized according to rational principles and has a pure a priori rational part, its metaphysical foundation. In the second edition Preface to the first Critique, Kant claims that his account of time explains the a priori possibility of Newton’s laws of motion. I argue that Kant’s proof of the law of inertia fails, and that this casts doubt on Kant’s enterprise of providing a priori foundations for Newton’s (...) physics. (shrink)

Although much recent social science and humanities work has been a revolt against simplification, this volume explores the contrast between simplicity and complexity to reveal that this dichotomy, itself, is too simplistic. John Law and Annemarie Mol have gathered a distinguished panel of contributors to offer—particularly within the field of science studies—approaches to a theory of complexity, and at the same time a theoretical introduction to the topic. Indeed, they examine not only ways of relating to complexity but complexity (...) _in practice._ Individual essays study complexity from a variety of perspectives, addressing market behavior, medical interventions, aeronautical design, the governing of supranational states, ecology, roadbuilding, meteorology, the science of complexity itself, and the psychology of childhood trauma. Other topics include complex wholes in the sciences, moral complexity in seemingly amoral endeavors, and issues relating to the protection of African elephants. With a focus on such concepts as multiplicity, partial connections, and ebbs and flows, the collection includes narratives from Kenya, Great Britain, Papua New Guinea, the Netherlands, France, and the meetings of the European Commission, written by anthropologists, economists, philosophers, psychologists, sociologists, and scholars of science, technology, and society. _Contributors._ Andrew Barry, Steven D.

Humean compatibilism combines a Humean conception of laws of nature with a strong dual-ability condition for free will that requires that agents possess the ability to decide differently when they make a free decision. On the Humean view of laws of nature, laws of nature are taken to be contingent non-governing descriptions of significant regularities that obtain in the entire history of the universe. On Humean compatibilism, agents are taken to possess dual ability when making free decisions because what the (...) laws of nature will finally be is (at least partially) dependent upon how an agent decides. In this paper, I argue that the tenability of Humean compatibilism depends in part upon what theory of time is correct. More specifically, I argue that Humean compatibilism is untenable in a deterministic universe if eternalism is true. (shrink)

A detailed attempt to ground the topological properties of time in the laws of micro- and macro-physical processes. The reversible processes of mechanics are used to define an order among temporally separated events, which is invariant under reversals of time direction. So long as consideration is limited to a single isolated system, a time ensemble, the transfer of the reversibility of the constituent processes of such a system to the system as a whole makes it impossible to (...) define time direction by means of the entropy curve. The directionality of time, accordingly, can only be defined as the direction of the entropy increase of multiple systems, of a space ensemble. A macrostatistical definition of time direction is then based upon the causal relation. The author's view of causation is non-deterministic: the conjunction of two events is caused if they occur together more frequently than can be expected from their chance coincidence. Reichenbach's analyses and arguments are careful and thorough; the book as a whole is a solid achievement. -- M. F. (shrink)

In this paper I draw the distinction between intuitive and theory-relative accounts of the time reversal symmetry and identify problems with each. I then propose an alternative to these two types of accounts that steers a middle course between them and minimizes each account’s problems. This new account of time reversal requires that, when dealing with sets of physical theories that satisfy certain constraints, we determine all of the discrete symmetries of the physical laws we are interested in (...) and look for involutions that leave spatial coordinates unaffected and that act consistently across our physical laws. This new account of time reversal has the interesting feature that it makes the nature of the time reversal symmetry an empirical feature of the world without requiring us to assume that any particular physical theory is time reversal invariant from the start. Finally, I provide an analysis of several toy cases that reveals differences between my new account of time reversal and its competitors. (shrink)

Critique as a philosophical concept needs to be recast once it is linked to the possibility of a productive opening. In such a context critique has an important affinity to destruction and forms of inauguration. Working through writings of Marx and Walter Benjamin, specifically Benjamin's 'The Meaning of Time in the Moral World', destruction and inauguration are repositioned in terns of othering and the caesura of allowing.

Every process studied in any science other than physics defines an arrow of time – to say nothing for the directedness of the processes of causation, inference, memory, control, and counterfactual dependence that occur in everyday life. The discussion in this chapter is confined to the arrow of time as it occurs in physics. The chapter briefly discusses those features of microscopic physics, which seem to conflict with time asymmetry. It explains just how this conflict plays out (...) in the important context of thermodynamics and statistical mechanics. The chapter then reviews the main strategies available for resolving the conflict between reversible microdynamics and irreversible macrodynamics, working within the context of the quantitative, time‐irreversible evolution laws that seem to apply to large‐scale phenomena. Finally, it offers a broad the discussion covering other arrows of time within physics. (shrink)

We address the question of whether it is possible to operate a time machine by manipulating matter and energy so as to manufacture closed timelike curves. This question has received a great deal of attention in the physics literature, with attempts to prove no- go theorems based on classical general relativity and various hybrid theories serving as steps along the way towards quantum gravity. Despite the effort put into these no-go theorems, there is no widely accepted definition of a (...) time machine. We explain the conundrum that must be faced in providing a satisfactory definition and propose a resolution. Roughly, we require that all extensions of the time machine region contain closed timelike curves; the actions of the time machine operator are then sufficiently "potent" to guarantee that closed timelike curves appear. We then review no-go theorems based on classical general relativity, semi-classical quantum gravity, quantum field theory on curved spacetime, and Euclidean quantum gravity. Our verdict on the question of our title is that no result of sufficient generality to underwrite a confident "yes" has been proven. Our review of the no-go results does, however, highlight several foundational problems at the intersection of general relativity and quantum physics that lend substance to the search for an answer.

Microphysical laws are time reversible, but macrophysics, chemistry and biology are not. This paper explores how this asymmetry arises due to the cosmological context, where a non-local Direction of Time is imposed by the expansion of the universe. This situation is best represented by an Evolving Block Universe, where local arrows of time emerge in concordance with the Direction of Time because a global Past Condition results in the Second Law of Thermodynamics pointing to the future. (...) At the quantum level, the indefinite future changes to the definite past due to quantum wave function collapse events. (shrink)

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental (...) health was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)
