In this paper, I analyse Émilie Du Châtelet’s (1706–49) account of causation which, in turn, is crucial for understanding her philosophical main work, the Institutions de physique (1740/1742). So far, the topic of causation in Du Châtelet’s thought has received but little attention despite its importance. I will show that Du Châtelet’s account of physical causation is that of physical influx much in line with the position taken by some of the most prominent eighteenth-century German metaphysicians at (...) the time of the publication of her Institutions: Martin Knutzen (1713–49), Johann Peter Reusch (1691–1758) and the pre-Critical Immanuel Kant (1724–1804). I will argue that physical influx takes place at the level of simple substances or physical monads, and I will defend my interpretation against the main objection to physical influx: that it conflicts with Leibniz’s non-transfer argument. The ultimate metaphysical details regarding how physical influx has to be understood remain an issue, that of understanding the causality of the cause. This, however, is an issue that other causal theories face, too (in their own way). (shrink)

Before the story can be told, however, some stage-setting is necessary. First, it is important to be clear about the most basic doctrines of Pre-established Harmony, Occasionalism, and Physical Influx. Physical Influx asserts intersubstantial causation amongst finite substances. For instance, when I appear to kick a ball, I really am the cause of the ball's motion. Pre-established Harmony denies intersubstantial causation, but affirms intrasubstantial causation. According to Pre-established Harmony, then, I am not the cause of the (...) ball's motion, but rather the ball is simply causing itself to move. Occasionalism, like Pre-established Harmony, denies intersubstantial causation, but, unlike Pre-established Harmony, it denies intrasubstantial causation as well. Occasionalism typically asserts that God alone, that is, an infinite substance, is the cause of all changes, and thus of the ball's motion. Though there are other ways of defining these causal theories, this way has the advantage that the causal theories form an exhaustive disjunction. (shrink)

In order to link fine-tuning in physics with spiritual influx, I propose that the highest degree in physics is where ‘ends’ are received in physics. By ends, I refer to what it is that determines the means or causes in physics, and what it is that manages or influences to basis parameters (masses and charge values) of the quantum fields. This is fine-tuning, in the sense that it occurs not just for the whole universe (in the Big Bang, for (...) example), but locally. That is, this fine-tuning is different at each time, and in point in space. Thus this influx can be specific to living organisms, and can occur at all the needed scales and levels in psychology and biology, namely every day and every micros-second of our lives. (shrink)

The present paper aims to provide an overview on Kant’s dealing with the main theories of causality which were proposed and discussed in his time. The goal is to show that, since the pre-critical period, he has never simply accepted the theories of causality that he could find in second-scholastic sources, but has always tried to develop an original position. Starting from a general acceptance of the theory of the “physical influx”, Kant tries to amend this theory, as (...) it had been roughly provided by Knutzen and Crusius. This emendation is carried out through elements coming from the Leibnitian tradition. But neither in this field Kant totally embraces the Wolffian, as well as the Baumgartenian model. The paper tries also to shed light on the way in which the critical conception of space allows Kant to fulfill his original theory of causality as an amended version of the physical influx. (shrink)

For the physicalist, the mind-body problem is the problem of finding a place for the mind in a world that is fundamentally physical. What does “fundamentally physical” mean? I think any physicalist will accept at least the following two claims. First, the world contains nothing but bits of matter and aggregates of bits of matter. There are no Cartesian souls, or Hegelian spirits, or neo-vitalist entelechies—as the emergentist C. Lloyd Morgan put it, no “alien influx” into the (...) natural order. This ontological thesis is sometimes called “ontological physicalism”. Second, we have the supervenience thesis: physical facts determine all the facts, and the physical properties of a thing determine all its properties. At this point, then, the world looks like this: all the things that exist are physical things—either basic bits of matter or wholly made up of bits of matter. These physical things have properties. What properties? First, there are basic physical properties, like mass, size, shape, electric charge, and so on—properties and magnitudes in terms of which laws of physics are formulated. But some properties of complex physical systems, like biological organisms, seem prima facie nonphysical—at least, they are not among the properties investigated in physics or the physical sciences. Prominent among them are mental properties—beliefs, desires, sensations, emotions, and the rest. The supervenience thesis says that such properties are fixed by the physical properties of the systems that have them; once the physical properties of a system are fixed, that fixes all of its properties. And yet property dualists, or nonreductive physicalists, maintain that although certain non-physical properties are determined by physical properties, they are irreducible to, and remain distinct from, physical properties. Although thoughts and pains are determined by the biology, and ultimately physicochemistry, of an organism, they are not biological/physical properties themselves, and there exists a special autonomous science of psychology, or cognitive science, that is responsible for investigating them.

Eric Voegelin’s writings on the historical development of the concept of race in the early 1930s are important to philosophy today in part because they provide a model upon which scholars can further integrate modern philosophy with the critical philosophy of race. In constructing his history, Voegelin’s methodological orientation depends on the centrality of both Kant’s work and the problem of the mind–body union to the concept of race. This essay asks how one might hold these premises if Kant seems (...) to reject the dominant approach to the mind–body union in the mid-eighteenth century, physical influx, and then go on to publish several essays on race that do not thematize that doctrine in any way. I argue that Kant’s racial union of mind and body cannot be understood as an interaction in space, as his contemporaries had presumed. Rather, the union must be approached as a repetition in time. In this way, Kant’s four racial categories are not merely a part of the mind–body problem, but instead each is a veritable mind–body union. This permits the conclusion that ‘race’, as Kant understood it, is a viable solution to the mind–body problem. (shrink)

The causal closure of the physical world is assumed everywhere in physics but has little empirical support within living organisms. For the spiritual to have effects in nature, and make a difference there, the laws of physical nature would have to be modified or extended. I propose that the renormalized parameters of quantum field theory (masses and charges) are available to be varied locally in order to achieve ends in nature. This is not adding extra forces to nature (...) but rescaling the forces which already exist. We separate metric time in 4 dimensions from process time as the order of actualization of potentialities. This is to allow iterative forward and reverse steps in metric time to influence intermediate variations in the vacuum permittivities to move charged bodies towards achieve specific targets at a later time. Then mental or spiritual influx could have effects in nature, and these should be measurable in biophysics experiments. With this proposal, we see after some centuries how ‘final causes’ could once again be seen active in nature. (shrink)

This paper considers Kant’s conception of force and causality in his early pre-Critical writings, arguing that this conception is best understood by way of contrast with his immediate predecessors, such as Christian Wolff, Alexander Baumgarten, Georg Friedrich Meier, Martin Knutzen, and Christian August Crusius, and in terms of the scientific context of natural philosophy at the time. Accordingly, in the True estimation Kant conceives of force in terms of activity rather than in terms of specific effects, such as motion. Kant’s (...) explicit arguments in the Nova dilucidatio for physical influx are directed primarily against the conception of grounds and existence held by Wolff, Baumgarten, and Meier, and only secondarily against Leibniz. Finally, Kant’s reconciliation of the infinite divisibility of space and the unity of monads in the Physical monadology is designed to respond to objections that could be raised naturally by Wolff and Baumgarten.Author Keywords: Kant; Pre-Critical; Force, Causality; Wolff; Leibniz.

I discuss the philosophical significance of Kant's great cosmological work of 1755, the Universal Natural History. I discuss how Kant's interest in Newtonian universal forces led him to affirm a peculiar version of the physical influx theory. I argue that Kant's speculations about life on other planets are highly significant because they point to a key feature of Kant's theory of physical influx, namely that "the nimble motions of the body" stand as necessary conditions of the (...) possibility of knowledge. This work directs us to an important topic that has received little scholarly interest: the relation between the body and knowledge in Kant's philosophical writings. (shrink)

Sufficiently grounding the origin of sense-perceptions in the mind is an issue that has concerned philosophers for a long time, and remains an issue even today. In eighteenth-century Germany prior to the publication of Kant’s Critical philosophy, the two main competing theories to causally ground sense-perceptions were pre-established harmony and physical influx, the latter of which ultimately carried the day. A third option had been around in the seventeenth century: occasionalism. However, historians of philosophy believe this option to (...) have entirely disappeared in the eighteenth century. I will show that this is not the case. In this paper, I focus on one influential German occasionalist: Gottfried Ploucquet (1716–90). Ploucquet not only criticizes Leibniz’s theory of pre-established harmony for providing an ultimately ungrounded, subjective, and arbitrary account of the origin of sense-perceptions, but also presents his own daring alternative: a representationalist-occasionalist theory that locates the objective ground of sense-perceptions in the divine mind.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 443-445 [Access article in PDF] Martin Schönfeld. The Philosophy of the Young Kant: The Precritical Project. New York: Oxford University Press, 2000. Pp. xv + 348. Cloth, $55.00. Kant's precritical philosophy has often been judged as lacking continuity, originality, and, indeed, philosophical relevance. Martin Schönfeld's impressive new study disputes this assessment, claiming instead that "the philosophy of the young Kant reveals (...) a greater unity and a more interesting coherence than previously assumed" (245). The author further argues that Kant's precritical thought is philosophically interesting in its own right. Schönfeld is to be commended for his successful refutation of the standard caricature and for deftly defending his reading of this formative period in Kant's thought. Recent years have seen a number of similar attempts to rehabilitate Kant's precritical thought, but Schönfeld's study will no doubt become the standard against which future scholarship is measured. [End Page 443]Schönfeld locates the unity of Kant's precritical philosophy in his purported "grand synthesis of the Newtonian model of nature with three assumptions of metaphysics: the purposive development of nature, the possibility of a morally relevant freedom, and the existence of God" (209). Schönfeld divides Kant's precritical philosophy into three periods comprising (1) Kant's initial failure during the 1740s to formulate a non-Newtonian philosophy of nature, (2) his conversion to Newtonianism in the 1750s (and the constructive philosophizing of this period), and (3) the period of intense self-criticism in the 1760s leading to the collapse of the precritical project. The originality of Schönfeld's typology is evident since many scholars claim that Kant was a Newtonian ab initio. In addition, Schönfeld claims that the precritical project ends with the "Dreams of a Spirit-Seer" (1766), a departure from the orthodox extension of the project to the "Inaugural Dissertation" (1770).Such readings are driven by the author's generally trenchant analyses of Kant's attempt to construct a unified philosophy of nature. In this regard, Schönfeld's analysis of Kant's attempt to reconcile physical processes and purposiveness in the "Universal Natural History" (1755) is particularly insightful; and Kant's attempts to account for the compatibility of determinism and human freedom in the "New Elucidation" (1755) and to formulate a theory of active matter in the "Physical Monadology" (1766) receive readings of a similarly high caliber. In addition, Schönfeld's extensive bibliography and his many references to thinkers now long-forgotten—yet indispensable for understanding Kant's early thought (e.g., Georg Bilfinger, a Wolffian thinker and source for Kant's lifelong strategy of seeking a via media between opposing positions)—are invaluable research tools.Also deserving mention is Schönfeld's examination of the "Dreams" essay. Once thought to be a mere critique of Swedenborg's mysticism, this work actually marks the beginning of Kant's doubts regarding the very possibility of speculative metaphysics. The precritical philosophy is largely concerned with the nature of real interaction between substances—contra occasionalist and pre-established harmony theories—and with Kant's interpretation of physical influx that grounds the same. Yet Kant realizes in the "Dreams" that his own account of a commercium of substances (as well as his claims regarding the soul) seems to lead quite naturally to the notion of a divine influx governing the interaction of disembodied spirits (regarding which Swedenborg purported to have first-hand experience). This realization, Schönfeld argues, motivates the collapse of the precritical project and Kant's recognition that an examination of mental capabilities must precede any speculation regarding nonsensible objects. It is to Schönfeld's credit that he takes this text, which is usually either ignored or ridiculed, seriously and presents a comprehensive and cogent reading of the same.Though generally successful in defending his reading of the precritical Kant, some of Schönfeld's positions are rather suspect. Indeed, Schönfeld claims that "in the 1740s, Kant either rejected Newtonian ideas out of hand, or he... (shrink)

Kant’s pre-1770 philosophy responded to the mind-body problem by applying a theory of “physical influx”. His encounter with Swedenborg’s mysticism, however, left him disillusioned with any dualist solution to Descartes’ problem. One of the major goals of the Critical philosophy was to provide a completely new solution to the mind-body problem. Kant’s new solution is “perspectival” in the sense that all Critical theories are perspectival: it acknowledges a deep truth in both of the controversy’s extremes (i.e., what we (...) might nowadays call eliminative materialism and an absolutely ideal folk psychology), by viewing both as ways of considering the issue, rather than as the only correct approach. Once we take into account its perspectival character, a new way of understanding Kant’s philosophy of mind emerges. The mind is no longer separate from the body, but is a manifestation of it, viewed from another (specifically human, rational) perspective. Kant’s transcendental conditions of knowledge (spatio-temporal intuition, categorial conception, and principled schematization) do not portray the mind as somehow creating the physical world; rather, they imply the opposite, that knowledge of objects is necessarily structured by a set of unconscious assumptions about the physical world. Our pre-conscious (or pre-mental, in Descartes’ sense of “mental”) encounter with an assumed spatio-temporal, causal nexus is entirely physical. A reincarnated Kant’s solution to today’s mind-body problem would be: eliminative materialism is good science; but only the “explanatory idealist” can consistently be an eliminative materialist. Philosophically, multiple perspectives are necessary in order to understand anything we say or do. (shrink)

The main topic of the following dissertation is Kant's Third Analogy of Experience, which asserts that one must posit a bond of mutual interaction in order to judge that two substances exist simultaneously. Part One considers the Third Analogy proper and reconstructs two plausible arguments for its main claim. Contrary to the view of most commentators , Kant is entitled to a strong causal notion of mutual interaction. Part Two considers the historical debate between proponents of Pre-established Harmony, Occasionalism, and (...) Physical Influx and how the Third Analogy can be seen as Kant's most developed version of Physical Influx. Thus, we see that Kant's concern with causality is not exhausted by his reply to Hume in the Second Analogy of Experience. For Kant is clearly concerned to attack the rationalist tradition by criticizing Leibniz's and Wolff's Pre-established Harmony, on the one hand, and the Cartesians' and Malebranche's Occasionalism, on the other hand. Part Three considers the argumentative structure of Kant's Metaphysische Anfangsgrunde der Naturwissenschaft and how the Third Analogy relates to this work. Contrary to what one might expect, the MAdN does not proceed by first presupposing a Principle from the first Critique and then substituting in the concept of matter. Rather, its substantial results are obtained through an extended transcendental argument showing how we can have experience of objects of outer sense . Further, we see how the abstract notion of mutual interaction involved in the Third Analogy becomes more specific in the MAdN since two of the most important features of its central notion of matter, namely the capacities of filling a space and of communicating motion, require attractive and repulsive forces and action and reaction, both instances of mutual interaction. These three lines of argument establish that the Third Analogy of Experience both constitutes a crucial part of Kant's position and presents a philosophically plausible view. (shrink)

One of the most pressing philosophical problems in early modern Europe concerned how the soul and body could form a unity, or, as many understood it, how these two substances could work together. It was widely believed that there were three (and only three) hypotheses regarding the union of soul and body: (1) physical influence, (2) occasionalism, and (3) pre-established harmony. However, in 1763, a fourth hypothesis was put forward by the French thinker André-Pierre Le Guay de Prémontval (1716–1764). (...) Prémontval’s hypothesis, given the grand name of “psychocracy” (i.e., the dominion or the rule of the soul), held that there was a real influence between soul and body, but that this was an immaterial kind of influence as opposed to the physical kind that had been entertained heretofore. Prémontval’s hypothesis is the focus of this paper. I shall begin by sketching out the details of Prémontval’s hypothesis (Section 1), then proceed to consider its claims to constitute a true fourth hypothesis distinct from the other three (Section 2), before closing by briefly considering two objections and the responses either that Prémontval himself made or that may be made on his behalf (Section 3).

The paper aims to sketch Kant’s response to the mind-body problem in his first work, Thoughts on the true estimation of living forces (1747). This is accomplished by first examining the origins of the problem in Descartes, then exploring the traditional responses to the problem, occasionalism, pre-established harmony, and physical influx. Finally, the paper positions Kant as a proponent of physical influx and highlights the unique features and challenges of his perspective.

This collection of twelve essays reexamines Kant’s considered attitude toward particular sciences so as to reevaluate his natural philosophy and its relation to critique, and shows how Kant tries to develop a unified natural philosophy that nevertheless recognizes and respects the diverse standards implicit in various sciences. Manfred Kuehn outlines the intellectual situation at Königsberg at the end of Kant’s schooling, with focus on competing accounts of relations among substances—real change physical influx, occasionalism, and universal harmony—arguing centrally that (...) Kant’s Thoughts on the True Estimation of Living Forces was an act of rebellion against Martin Knutzen, leader of the dominating, anti-Wolffian Pietists, who argued for the sufficiency of influx and the dangers of preestablished harmony. Kant argued that while physical influx correctly accounts for some kinds of changes, a full account of reality requires harmony not only of the internal states of substances, but, going beyond the Leibnizians, external interactions of substances also.

Esta contribución examina la solución al problema mente-cuerpo que Kant formula en el marco de su primera explicación causal. Se analiza tanto el planteamiento metafísico como la solución interaccionista de Kant a este problema en su obra sobre las “fuerzas vivas” y, mediante orientaciones metodológicas de la historia intelectual, se contrastan con los planteamientos y soluciones de dos pensadores que influyeron en la formación del pensamiento kantiano: Marquardt y Knutzen, exponentes de algunas de las principales doctrinas causales de la época (...) como la de la armonía preestablecida y el influjo físico. En un sentido, la solución kantiana se plantea como una vía intermedia entre estas dos doctrinas y, en otro, como una postura crítica frente a ambas. (shrink)

This article engages with debates about the status and geographies of colonial science by arguing for the significance of meteorological knowledge making in late nineteenth- and early twentieth-century Mauritius. The article focuses on how tropical storms were imagined, theorized and anticipated by an isolated – but by no means peripheral – cast of meteorologists who positioned Mauritius as an important centre of calculation in an expanding infrastructure of maritime meteorology. Charles Meldrum in particular earned renown in the mid-nineteenth century for (...) theoretical insights into cyclone behaviour and for achieving an unprecedented spatial reach in synoptic meteorology. But as the influx of weather data dried up towards the end of the century, attention turned to developing practices of ‘single-station forecasting’, by which cyclones might be foreseen and predicted not through extended observational networks, but by careful study of the behaviour of one set of instruments in one place. These practices created new moral economies of risk and responsibility, as well as a ‘poetry’, as one meteorologist described it, in the instrumental, sensory and imaginative engagement with a violent atmospheric environment. Colonial Indian Ocean ‘cyclonology’ offers an opportunity to reflect on how the physical, economic and cultural geographies of an island colony combined to produce spaces of weather observation defined by both connection and disconnection, the latter to be overcome not only by infrastructure, but also by the imagination.

Crick and Koch’s 1990 “neurobiological theory of consciousness” sparked the race for the physical correlates of subjective experience. 30 years later, cognitive sciences trend toward consideration of the brain’s electromagnetic field as the primary seat of consciousness, the “to be” of the individual. Recent advancements in laboratory tools have preceded an influx of studies reporting a synchronization between the neuronally generated EM fields of interacting individuals. An embodied and enactive neuroscientific approach has gained traction in the wake of (...) these findings wherein consciousness and cognition are theorized to be regulated and distributed beyond the individual. We approach this frontier to extend the implications of person-to-person synchrony to propose a process of combination whereby coupled individual agents merge into a hierarchical cognitive system to which they are subsidiary. Such is to say, the complex mammalian consciousness humans possess may not be the tip of the iceberg, but another step in a succeeding staircase. To this end, the axioms and conjectures of General Resonance Theory are utilized to describe this phenomenon of interpersonal resonant combination. Our proposal describes a coupled system of spatially distributed EM fields that are synchronized through recurrent, entraining behavioral interactions. The system, having achieved sufficient synchronization, enjoys an optimization of information flow that alters the conscious states of its merging agents and enhances group performance capabilities. In the race for the neurobiological correlates of subjective experience, we attempt the first steps in the journey toward defining the physical basis of “group consciousness.” The establishment of a concrete account of the combination of consciousness at a scale superseding individual human consciousness remains speculation, but our suggested approach provides a framework for empirical testing of these possibilities.

The sudden move to online learning due to the COVID-19 pandemic has created an influx of epistemological, psycho-social, emotional and financial challenges for first year students. Lecturers and academics had to find creative and sustainable ways of ensuring that all students were epistemologically included. New policies and practices were introduced rapidly at universities to facilitate the unavoidable move to online learning. As initial teacher educators at a public University in South Africa we noted that the sudden move to working (...) online has presented various challenges to first year students’ overall well-being which has further exacerbated issues of exclusion and marginalization for many. We argue that it is against this backdrop that this paper explores how the move to online learning has affected first year students’ overall well-being, at one teacher education institution. The Index for Inclusive Education was used as a theoretical lens to explore student’s perceptions of the institution’s policy, teaching and learning practices, and the institutional culture during this period. One hundred and eighty-seven purposively selected first year students participated in this qualitative, phenomenological research study. Data were collected by means of open-ended questionnaires. Responses were categorized by means of an emergent thematic analysis. The findings indicated that online learning compromised various aspects of well-being including physical, emotional, psycho-social and financial well-being for many students. The experiences of online learning and impact on well-being did, however, differ across students depending on their individual contexts and circumstances indicating that considerations of well-being need to take contextual realities into account to support the well-being and learning of all. We recommend that higher education institutions prioritize the psycho-social, emotional, and financial well-being of students during the period of online learning and not just the pedagogic needs of the qualification.

The year 2019 witnessed the 20th Jubileum of the Växjö conference series on quantum foundations and probability in physics. This has been the longest running series of conferences on the subject in history. Many old and new friendships were forged at Linnaeus University and the beautiful surrounding lakes of Småland, where once yearly everyone gathers to renew the debate and report their latest progress. 2019 also represents the Porcelain Anniversary—18 years—of the point of view on quantum theory known as QBism. (...) In this regard, the 2001 meeting in the series was pivotal in more ways than one. Not only did it instigate Fuchs’s break [1] from the earlier (Jaynes style) “objective Bayesianism” and neo-Copenhagen thinking of Caves et al. [2], but it was the first meeting at an international scale to indicate that the quantum information revolution might have something genuine to contribute to quantum foundational thought. That meeting set the pace far beyond Växjö by the participation of a number of luminaries of quantum information: The late Asher Peres, Daniel Greenberger, David Mermin, Herbert Bernstein, Carlton Caves, Rüdiger Schack, Richard Jozsa, Benjamin Schumacher, and John Smolin. One could almost hear a battle cry echo from the woods, “Quantum foundations from quantum information or die!” The foundations debate had turned so stale by the time, it would surely die without an influx of new thinking.

The aim of the article is the analysis of the principle of fair play which co-creates an axiological basis of contemporary sport as well as its basic moral category. The constituents of fair play are, first of all, responsibility and justice. Both values are central values, connected with each other, and also closely connected with other values inscribed in fair play, e.g. respect, solidarity, care or honesty. The conducted analysis shows that the rules of fair play connected with formal responsibility (...) and justice, i.e. following the rules and caring for the integrity of sport, are constituent for both sport and esports, whereas the rules of fair play connected with acting responsibly, i.e. respect and avoiding victory at all costs, are hard to realise in esports. It results from the fact that contact between the players is digitally mediated. Hence, apart from gestures and verbal communication, display of respect towards a player during a game is impeded, as is still more a spontaneous reaction to his or her being hurt. Also, avoiding winning at all costs is impeded in esports, as activities directed at obtaining victory are built into the content of the game and therefore should be carried out in accordance with the regulations, from the technical and tactical side and according to the possessed skills. However, it is possible to stop the game when the connection with the other player is suddenly interrupted. From a fair-play perspective also the content of some games employed in esports is questionable, as it assumes contesting moral rules, which in turn is at variance with the realisation of integrative, educational and formative functions of esports in society.

In Physical Realization, Sydney Shoemaker considers the question of how physicalism can be true: how can all facts about the world, including mental ones, be constituted by facts about the distribution in the world of physical properties? Physicalism requires that the mental properties of a person are 'realized in' the physical properties of that person, and that all instantiations of properties in macroscopic objects are realized in microphysical states of affairs. Shoemaker offers an account of both these (...) sorts of realization, one which allows the realized properties to be causally efficacious. He also explores the implications of this account for a wide range of metaphysical issues, including the nature of persistence through time, the problem of material constitution, the possibility of emergent properties, and the nature of phenomenal consciousness.

According to the algebraic approach to spacetime, a thoroughgoing dynamicism, physical fields exist without an underlying manifold. This view is usually implemented by postulating an algebraic structure (e.g., commutative ring) of scalar-valued functions, which can be interpreted as representing a scalar field, and deriving other structures from it. In this work, we point out that this leads to the unjustified primacy of an undetermined scalar field. Instead, we propose to consider algebraic structures in which all (and only) physical (...) fields are primitive. We explain how the theory of natural operations in differential geometry—the modern formalism behind classifying diffeomorphism-invariant constructions—can be used to obtain concrete implementations of this idea for any given collection of fields. For concrete examples, we illustrate how our approach applies to a number of particular physical fields, including electrodynamics coupled to a Weyl spinor. (shrink)

It is evident to every earnest thinker that a theory of time is in a very significant sense implicit in any philosophy of nature. Indeed, the search for a time standard independent of the variation of the earth's speed, the maximum variation being slightly more than one-thousandth of a second, involves the most basic concepts and principles of physical theory.

The author has recently shown that a mathematical question regarding the fundamental constituents of hardrons cannot be resolved unless the classical axioms of nonfinite mathematics are revised in such a way as to produce a new theory of particle motion in continuous space-time. Under this new theory, the instantaneous position of a moving object has a magnitude that is increasing as the object's velocity. The purpose of this paper is to show that, quite apart from the question of Cantorian axiomatics, (...) the new theory of motion is more consistent with what physicists really believe than the traditional theory of motion.

Covid-19 lockdown restrictions constitute a population-wide “life-change event” disrupting normal daily routines. It was proposed that as a result of these lockdown restrictions, physical activity levels would likely decline. However, it could also be argued that lifestyle disruption may result in the formation of increased physical activity habits. Using a longitudinal design, the purpose of this study was to investigate changes in physical activity of different intensities, across individuals who differed in activity levels prior to lockdown restrictions (...) being imposed, and across three time periods: pre-, during- and post-lockdown. This study also examined the extent to which the experience of daily hassles explained any changes in physical activity. A convenience sample recruited through social media, provided data from an online survey administered during weeks 2–3 of a 5-week lockdown and 231 participants provided complete data again 6 weeks post-lockdown. Participants completed the International Physical Activity Questionnaire–Short Form and the Daily Hassles Scale. Results showed that vigorous and moderate intensity PA were significantly lower during- and post-lockdown compared to pre-lockdown in those individuals who had been highly active pre-lockdown. In contrast, for moderately active individuals pre-lockdown, vigorous and moderate intensity PA was significantly higher during-lockdown compared to pre-lockdown, and these increased levels of vigorous PA were maintained post-lockdown. Participants experienced daily hassles due to inner concerns, time pressures, family, and financial concerns to the same extent during- and post-lockdown. Those daily hassles had a small negative predictive effect on post-lockdown PA. It appears that to understand the effect of COVID-19 restrictions on PA, the activity status of individuals pre-lockdown needs to be taken into account. The daily hassles appeared to play a role in post-lockdown PA behavior, but future research should investigate why these results occurred. (shrink)

In this paper, I reconstruct an argument of Aristidis Arageorgis against empirical underdetermination of the state of a physical system in a C*-algebraic setting and explore its soundness. The argument, aiming against algebraic imperialism, the operationalist attitude which characterized the first steps of Algebraic Quantum Field Theory, is based on two topological properties of the state space: being T1 and being first countable in the weak*-topology. The first property is possessed trivially by the state space while the latter is (...) highly non-trivial, and it can be derived from the assumption of the algebra of observables’ separability. I present some cases of classical and of quantum systems which satisfy the separability condition, and others which do not, and relate these facts to the dimension of the algebra and to whether it is a von Neumann algebra. Namely, I show that while in the case of finite-dimensional algebras of observables the argument is conclusive, in the case of infinite-dimensional von Neumann algebras it is not. In addition, there are cases of infinite-dimensional quasilocal algebras in which the argument is conclusive. Finally, I discuss Porrmann's construction of a net of local separable algebras in Minkowski spacetime which satisfies the basic postulates of Algebraic Quantum Field Theory. (shrink)

The new normal has made social distancing a new way of experiencing sociality. Social neuroscience has for a long time been concerned with studying the beneficial effects of social relationships, of physical contact. It is known that physical contact activates neurophysiological processes that reduce the perception of discomfort and even physical pain. So in the absence of physical contact, our social brain may be modulated differently when we are with others. But what could be the long-term (...) effects of this normality? This mini-review focuses on highlighting with the support of social neuroscience evidence such as isolation, distancing can affect people’s health. (shrink)

This paper has three aims. First, I aim to stress the importance of the issue of the dispositional/categorical distinction in the light of the evident failure of the traditional formulation, which is in terms of conditional entailment. Second, I consider one radical new alternative on offer from Ullin Place: intentionality as the mark of the dispositional. I explain the appeal of physical intentionality, but show it ultimately to be unacceptable. Finally, I suggest what would be a better theory. If (...) we take disposition ascriptions to be functional characterizations of properties, then we can explain all that was appealing about the new alternative without the unacceptable consequences.

A zombie world is a possible world in which all the microphysical truths are identical to the truths in our world, but no one is phenomenally conscious. A zombie is an individual in a possible world whose microphysical truths are identical to the microphysical truths of an individual in our world, but who has none of the phenomenal conscious experiences of the individual in our world. An inverted is an individual in a possible world whose microphysical truths are not only (...) identical to the microphysical truths of an individual in our world, but who also has phenomenal conscious experiences. These experiences, however, are qualitatively different from the ones of the individual in our world. The first premise of Chalmers’ conceivability argument against materialism is that a zombie world, a zombie and an inverted are ideally conceivable. This paper rejects this premise in claiming that: given that current physics does not allow philosophers to establish a clear concept of the physical that could be opposed to something else non-physical, a zombie world, a zombie and an inverted are merely prima facie, but not ideally conceivable. This objection is called the Obscurity of the Physical Objection.Key-words: Zombies, qualia, conceivability, possibility, physics. (shrink)

We describe a possible physical device that computes a function that cannot be computed by a Turing machine. The device is physical in the sense that it is compatible with General Relativity. We discuss some objections, focusing on those which deny that the device is either a computer or computes a function that is not Turing computable. Finally, we argue that the existence of the device does not refute the Church–Turing thesis, but nevertheless may be a counterexample to (...) Gandy's thesis. (shrink)

The author claims to have developed interactional expertise in gravitational wave physics without engaging with the mathematical or quantitative aspects of the subject. Is this possible? In other words, is it possible to understand the physical world at a high enough level to argue and make judgments about it without the corresponding mathematics? This question is empirically approached in three ways: anecdotes about non-mathematical physicists are presented; the author undertakes a reflective reading of a passage of physics, first without (...) going through the maths and then after engaging with it and discusses the difference between the experiences; the aforementioned exercise gives rise to a table of Levels of Understanding of mathematics, and physicists are asked about the level mathematical understanding they applied when they last read a paper. Each phase of empirical research suggests that mathematics is not as central to gaining an understanding of physics as it is often said to be. This does not mean that mathematics is not central to physics, merely that it is not essential for every physicist to be an accomplished mathematician, and that a division of labour model is adequate. This, in turn, suggests that a stream of undergraduate physics education with fewer mathematical hurdles should be developed, making it easier to train wider groups of people in physical science comprehension.Keywords: Physics; Mathematics; Interactional expertise; Physics education; Mathematical literacy; Scientific literacy.

A paradigm shift in public health and medicine has broadened the field from a singular focus on the ill effects of negative states and psychopathology to an expanded view that examines protective psychological assets that may promote improved physical health and longevity. We summarize recent evidence of the link between psychological well-being and physical health, with particular attention to outcomes of mortality and chronic disease incidence and progression. Within this evolving discipline there remain controversies and lessons to be (...) learned. We discuss measurement-related challenges, concerns about the quality of the evidence, and other shortcomings in the field, along with a brief discussion of hypothesized biobehavioral mechanisms involved. Finally, we suggest next steps to move the field forward. (shrink)

The Mental and the Physical was first published in 1967. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Professor Feigl's essay "The 'Mental' and the 'Physical'" has provoked a great deal of comment, criticism, and discussion since it first appeared as a part of the content of Volume II of the Minnesota Studies in the Philosophy of Science about ten years ago. (...) Now Professor Feigl takes account of the critical discussions and presents his own comments with respect to the most important points raised in the criticisms. The essay itself is presented here in full, along with the postscript. The British Journal for the Philosophy of Science has called the essay "a 'super-colossal' survey of the mind-body problem." In its review of the earlier book containing the essay, Thought said: "This essay deserves careful reading by every philosopher concerned with genuine philosophical dialogue.". (shrink)

The ArgumentOne of the earliest arguments for Copernicanism was a widely accepted fact: that on a horizontal plane a body subject to no external resistance can be set in motion by the smallest of all possible forces. This fact was contrary to Aristotelian physics; but it was a physical argument (by abduction) for the possibility of the Copernican world system. For it would be explained if that system was true or at least possible.Galileo argued: only nonviolent motions can be (...) caused by the smallest of all possible forces; hence resistance-free horizontal motions are nonviolent; this confirms Copernicanism insofar as it designates the rotations of celestial spheres (being resistance-free horizontal motions) as nonviolent.Galileo's argument was compatible with (and supportive of) the specific Copernican version of impetus mechanics; but it was also compatible with a (somewhat qualified) principle of inertia. Thus it promoted decisively the transition from impetus mechanics to classical inertial mechanics. (shrink)
