Aristotle argues that time depends on soul to count it, but adds that motion, which makes time what it is, may be independent of soul. The claim that time depends on soul or mind implies that there is at least one measurable property of natural beings that exists because of the mind’s activity. This paper argues that for Aristotle time depends partly on soul, but more importantly on motion, which defines a continuum. This argument offers a robust metaphysics (...) of time. In contrast to modern philosophy of physics, for Aristotle the continuum of motion is prior in being to time, while time is a hybrid of the real continuum of motion and the activity of mind.

An interdisciplinary exploration of the forms, implications, and potentials of cinematic thinking.

A new take on our bio-cultural evolution explores how the "inner theatre" of the brain and its "animal-human stages" are reflected in and shaped by the mirror of cinema. Vampire, werewolf, and ape-planet films are perennial favorites—perhaps because they speak to something primal in human nature. This intriguing volume examines such films in light of the latest developments in neuroscience, revealing ways in which animal-human monster movies reflect and affect what we naturally imagine in our minds. Examining specific films as (...) well as early cave images, the book discusses how certain creatures on rock walls and movie screens express animal-to-human evolution and the structures of our brains. The book presents a new model of the human brain with its theatrical, cinematic, and animal elements. It also develops a theory of "rasa-catharsis" as the clarifying of emotions within and between spectators of the stage or screen, drawing on Eastern and Western aesthetics as well as current neuroscience. It focuses on the "inner movie theater" of memories, dreams, and reality representations, involving developmental stages, as well as the "hall of mirrors," ape-egos, and body-swapping identifications between human beings. Finally, the book shows how ironic twists onscreen—especially of contradictory emotions—might evoke a reappraisal of feelings, helping spectators to be more attentive to their own impulses. Through this interdisciplinary study, scholars, artists, and general readers will find a fresh way to understand the potential for interactive mindfulness and yet cathartic backfire between human brains—in cinema, in theater, and in daily life.

Amidst the seemingly endless books on more and more narrowly specialized topics within politics, Mark Blitz offers something very different. Reason and Politics: The Nature of Political Phenomena examines the central phenomena of political life in order to clarify their meaning, source, and range. Blitz gives particular attention to the notions of freedom, rights, justice, virtue, power, property, nationalism, and the common good. At the same time, Blitz shows how, in order to understand political matters correctly, we must also (...) understand how they affect us directly. We do not merely theorize over political questions; we experience them. Blitz also considers matters such as the powers and motions of the soul, the nature of experience, and the varieties of pleasure and attachment. Living at a time when technological change makes it difficult even to claim convincingly that there are defining human characteristics and natural limits that we simply cannot change, Reason and Politics proposes that there are in fact basic phenomena not only in politics, but that make up human affairs as such. In examining these central phenomena in a lucid and articulate manner, this book makes a unique contribution not only to the study of politics but also to the study of philosophy more broadly. It will interest undergraduate and graduate students, political scientists and philosophers, those interested in politics, and general readers"-- Back cover. (shrink)

This paper reconstructs the relationship between the now, motion, and number in Aristotle to clarify the nature of the now, and, thereby, the relationship between motion and time. Although it is clear that for Aristotle motion, and, more generally, change, are prior to time, the nature of this priority is not clear. But if time is the number of motion, then the priority of motion can be grasped by examining his theory of number. This paper (...) aims to show that, just as numbers are generated by the soul, time is not presupposed by motion, but emerges through the soul’s articulation of motion. Time is co-constituted by the soul and motion. The now is the key to understanding both the contribution of motion and soul to the being of time. The now is part of the soul’s articulation of motion, and sets the stage for an act that distinguishes a unit from its underlying motion. The now, then, sets up an abstraction by which the soul generates the temporal number from motion. Reconstructing this account of abstraction allows us to formulate more strongly Aristotle’s claim to the ontological dependence of time on motion. The paper then gives a systematic overview of the relationships between the now and number in order to address the question of whether the now might be extended. It closes with an examination of the possibility that motion depends on time, and how universal time is possible. (shrink)

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. (...) When he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

Mere exposure, generally, entails influences of familiarity manipulations on affective dependent variables. Previously (Phaf & Rotteveel, 2005), we have argued that familiarity corresponds intrinsically to positive affect, and have extended the correspondence to novelty and negative affect. Here, we present two experiments that show reverse effects of affective manipulations on perceived familiarity. In Experiment 1 affectively valenced exteroceptive cues of approach and avoidance (e.g., apparent movement) modulated recognition bias of neutral targets. This finding suggests that our correspondence hypotheses can be (...) generalised to an important aspect of emotion, namely approach and avoidance tendencies. In Experiment 2 participants? emotional mood was manipulated within the Jacoby?Whitehouse paradigm and a pattern of results was obtained as if consciousness was manipulated. We interpret the latter results within the affective modulation framework (AMF), which postulates facilitation of nonconscious processing by positive affect and an enhancement of conscious processing by negative affect.

assumptions about the phenomena of interest with process models. Thus, phlogiston has been replaced by combustion, caloric by random thermal motion, and vital fluid by far- from-equilibrium self-reproducing organizations of process. The most significant exceptions to this historical pattern are found in studies of the mind. Here, substance assumptions are still ubiquitous, ranging from models of representation to those of emotions to personality and psychopathology. Substance assumptions do pernicious damage to our ability to understand such phenomena. In this discussion, (...) I will focus on the problem of representation. (shrink)

This international ensemble of scholars discuss Thomas Nail’s The Figure of the Migrant. These scholars represent various disciplines within the academy and divergent methodologies. One thing we share in common, though, is the opinion that the migrant needs to occupy a more significant place within our political theory and policy. Nail’s book is one of kinopolitics, that is, a politics of movement. It provides a kind of theory of social motion. According to Nail, the book offers a remedy to (...) problems in how the migrant is typically theorized, namely that the migrant is understood as a derivative figure in contrast to the stable denizen and the migrant is discussed through the lens of the state. His remedial maneuver mobilizes the potential to understand the figure of the migrant by placing the migrant in the primary position, by offering a political philosophy of the migrant. (shrink)

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (...) (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called “perceiving the present,” that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity. (shrink)

The history of mechanics has been extensively investigated in a number of historical works. The full story from the Greeks and medievals through the Scientific Revolution to the modern era is long and complex. But it is also incomplete. Studies to date have been admirably thorough in putting empirical discoveries into proper perspective and in making clear the great importance of mathematical innovations. But there has been surprisingly little regard for the role of thought experiments in the development of mechanics. (...) We attempt to rectify this, at least in part. After a brief account of Greek ideas of space and motion, we focus on late medieval and early modern physics, especially the development of inertial motion. In particular, we examine the thought experiments of Buridan, Oresme, and Galileo, which did so much to undermine Aristotle’s account of motion and lead the way to the modern concept of inertia.

Dynamically transforming the elements of any performing artist’s craft, this practical guide is a must-have for musicians, dancers, and actors. The handbook shows how artistic performance is embodied in the unification of three critical elements—motion, emotion, and love—demonstrating how it offers experiences and opportunities distinct from the nonperforming arts. Step-by-step guidelines are provided for building intentional and inspirational practice time, thereby enhancing the relationships between the source, the performer, and the audience. Illustrating how intentional movement invokes emotions from both (...) the performer and the audience and how the concept of love gives a performance humanity and life, this eye-opening exploration creates pathways for achieving true artistry.

Complexified Liénard–Wiechert potentials simplify the mathematics of Kerr–Newman particles. Here we constrain them by fiat to move along Bohmian trajectories to see if anything interesting occurs, as their equations of motion are not known. A covariant theory due to Stueckelberg is used. This paper deviates from the traditional Bohmian interpretation of quantum mechanics since the electromagnetic interactions of Kerr–Newman particles are dictated by general relativity. A Gaussian wave function is used to produce the Bohmian trajectories, which are found to (...) be multi-valued. A generalized analytic continuation is introduced which leads to an infinite number of trajectories. These include the entire set of Bohmian trajectories. This leads to multiple retarded times which come into play in complex space-time. If one weights these trajectories by their natural Bohmian weighting factors, then it is found that the particles do not radiate, that they are extended, and that they can have a finite electrostatic self energy, thus avoiding the usual divergence of the charged point particle. This effort does not in any way criticize or downplay the traditional Bohmian interpretation which does not assume the standard electromagnetic coupling to charged particles, but it suggests that a hybridization of Kerr–Newman particle theory with Bohmian mechanics might lead to interesting new physics, and maybe even the possibility of emergent quantum mechanics.

The Philosopher at the End of the Universe demonstrates how anyone can grasp the basic concepts of philosophy while still holding a bucket of popcorn. Mark Rowlands makes philosophy utterly relevant to our everyday lives and reveals its most potent messages using nothing more than a little humor and the plotlines of some of the most spectacular, expensive, high-octane films on the planet. Learn about: The Nature of Reality from The Matrix, Good and Evil from Star Wars, Morality from (...) Aliens, Personal Identity from Total Recall, The Mind-Body dilemma from Terminator, Free Will from Minority Report, Death and the Meaning of Life from Blade Runner, and much more. A search for knowledge about ourselves and the world around us with a star-studded cast that includes: Tom Cruise, Plato, Harrison Ford, Immanuel Kant, Arnold Schwarzenegger, Friedrich Nietzsche, Sigourney Weaver, René Descartes, and Keanu Reeves. Rowlands anchors his discussions in easily understood everyday terms and relates them in a manner easy to identify with. Interspersed with a ready joke or two, he wonderfully explains why those SciFi movies we love so much are much deeper than they appear to be on the surface. Mark Rowlands's entertaining and stimulating guide is perfect for anyone searching for knowledge of the world around us. If Keanu can understand Descartes surely everyone can. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Destruction and Transcendence in W. G. SebaldMark R. McCullohIFor all the Saturnine pessimism of W. G. Sebald's application of Walter Benjamin's view of historical process (an attitude toward history expounded upon at length in an influential work by Susan Sontag), the author's sense of irony about the human predicament is irrepressible. 1 Human beings seem destined to remain prisoners of various paradoxes—they both create and destroy, they are capable (...) of acts of love as well as bitterness and hate, they make efforts to document and communicate, but at the same time they tend to forget and are given to suppressing the truth, they are driven by ideals, yet remain hobbled by imperfection. Art and music, passed on from generation to generation, seem to be the most common way that human beings transcend the strictures of their imperfections, inadequacies, and their finitude. And to the extent that art indeed survives over time, and continues to be perceived and appreciated by beholders, the aesthetic enterprise succeeds. However, ultimately, as the Book of Ecclesiastes and Shelley's "Ozymandias" remind us, all human endeavor is in vain, and, to assume the perspective of physical cosmology for a moment—and in this regard Benjamin's cosmic vision appears painfully accurate—our speck of earth, dwarfed by a vast universe the true immensity of which has been revealed by the Hubble Telescope, will one day be ground to dust and debris like the rings of Saturn, and our sun will exist only as a burned-out hulk. But such a future world, devoid of beholders, and devoid of creators and their artifacts, is not Sebald's primary subject, even though it clearly forms the teleological backdrop for his third novel, The Rings of Saturn (1995, English version 1998). Rather, Sebald pursues his art in spite of a terminal prospect that will ultimately confront our [End Page 395] planet and solar system. His primary subject, the effect of trauma on individual and collective experience, is instead closely linked with the passing of Europe as a tradition, as an idea—as an idiosyncratic and innovative, but inherently corrupt contributor to cultural history. In the course of his narratives he also addresses the redemptive role of art in memorializing the past and attempting to capture the passing present. In both respects he attends to the humane and the sublime as well as the tragic and the grotesque.Paraphrasing the art historian Svetlana Alpers, one early reviewer of Sebald's novel Austerlitz (2001) points out the self-contradictory nature of preserving the transient moment in art:Why create visual art at all when everything on earth must be represented in its inexorable transitoriness; why paint earthly scenes with such incredible care and precision as if they were permanent? 2The care and precision of the painter's craft (in this case, the Dutch still-life painter David Bailly) are devoted to the representation of a scene that is by its very nature transient and even tenuous—like the scenes of sublime beauty in Sebald's fiction, the artist's depiction "courts and admits" its own fragility. What Bailly does visually, Sebald attempts in words. Take, for instance, the following passage from Vertigo, Sebald's first novel, which was titled in German (with considerably more irony) Schwindel. Gefühle 3 :At a hairpin bend I looked out of the turning bus down into the depths below and could see the turquoise surfaces of the Ferstein and Smaranger lakes, which, even when I was a child, on our first excursions into the Tyrol, had seemed to me the essence of all conceivable beauty.(p. 176)The author has already prepared the reader for this moment of awe by remarking on the otherworldly "slow-motion quality" of the waterfalls descending from the mountain cliffs and on the boulders in their screes spreading downwards into the wooded hillsides, "screes which reached from the mountains down into the forests like pale fingers into dark hair..." (p. 176). Examined closely, the passage in question suggests both the enduring power of natural beauty and, especially with its precise reference to an automobile long since out of production and unfamiliar to...

There is general agreement in mathematics about what continuity is. In this paper we examine how well the mathematical definition lines up with common sense notions. We use a recent paper by Hud Hudson as a point of departure. Hudson argues that two objects moving continuously can coincide for all but the last moment of their histories and yet be separated in space at the end of this last moment. It turns out that Hudson’s construction does not deliver mathematically continuous (...) motion, but the natural question then is whether there is any merit in the alternative definition of continuity that he implicitly invokes.

Issuing from a geometry with nonmetricity and torsion we build up a generalized classical electrodynamics. This geometrically founded theory is coordinate covariant, as well as gauge covariant in the Weyl sense. Photons having arbitrary mass, intrinsic magnetic currents, (magnetic monopoles), and electric currents exist in this framework. The field equations, and the equations of motion of charged (either electrically or magnetically) particles are derived from an action principle. It is shown that the interaction between magnetic monopoles is transmitted by (...) massive photons. On the other hand, the photon is massive only in the presence of magnetic currents. We obtained a static spherically symmetric solution, describing either the Reissner-Nordstrom metric of an electric monopole, or the metric and field of a magnetic monopole. The latter must be massive. In the absence of torsion and in the Einstein gauge one obtains the Einstein-Maxwell theory. (shrink)

The supertasks described by Perez Laraudogoitia, involving the dynamics of a system containing an infinite number of particles in a bounded region of space, are characterized by the nonconservation of energy and by the spontaneous motion of particles. We argue that these features arise from the inadequacy of the local, particle-by-particle description used to analyze the supertasks. A global analysis, involving embeddings in Hilbert spaces, clarifies these supertasks and avoids what we regard as their nonphysical features.

To evoke the impression of movement in the “immobile” image is one of the central motivations of the visual art, and the activating effect of images has been discussed in art psychology already some hundred years ago. However, this topic has up to now been largely neglected by the researchers in cognitive psychology and neuroscience. This study investigates – from an interdisciplinary perspective – the formation of lateralised instances of motion when an observer perceives movement in an image. A (...) first step was to identify images that evoke a perception of movement in a certain direction and to give this a rating. Reaction times leading to the engagement of a joystick following the presentation of images are used to evidence the postulated movement occasioned by the perception of movement in an image. Where the required direction of joystick moves matched the expected perception of movement direction in the image, considerably shorter reaction times were recorded. The experiment was able to prove a “movement-image compatibility effect” in observers of images. Based on this, the paper revisits and brings up to date the theses on motor sensory response to images which were developed in art psychology at the beginning of the 20th century. It furthermore contributes an embodiment theory interpretation to the prevalent representational explanation of compatibility effects. (shrink)

Cognitively modern human beings have language, art, science, religion, refined tool use, advanced music and dance, fashions of dress, and mathematics. Blue jays, border collies, dolphins, and bonobos do not. Only human beings have what we have, and this discontinuity in Life, this perspicuous Grand Difference, presents us with the most abiding and compelling scientific riddle of all. In The Way We Think, Gilles FauconnieRAnd I put forward the hypothesis that The Grand Difference arose in the following way . The (...) basic mental operation of conceptual integration, also known as ‘blending’, has been present and evolving in various species foRA long time, probably since early mammals, and there is no reason to doubt that many mammalian species aside from human beings have the ability to execute rudimentary forms of conceptual integration. Human beings evolved not an entirely different kind of mind, but instead the capacity for the strongest form of conceptual integration, known as ‘double- scope’ blending. Human beings are thus on a gradient with other species, but what a difference an extra step makes. Double-scope blending is the hallmark of cognitively modern human beings, and The Grand Difference is the product of double-scope blending. What is blending and why is it so important? As an illustration, consider our perception of a seal. The eyes of a seal are remarkably like the eyes of a human being. When we see a seal at the seashore, it is impossible to resist the conclusion that we and the seal share a category. Compelling and evident analogies leap out at us, between the seal’s appearance and ours, between the seal’s motion and ours. Our human eyes align toward an object as our limbs propel our bodies toward it, and it seems to be no different for the seal. Working from such analogies, we immediately forge a mental blend of ourselves and the seal. The result is a conception of a seal that has not only all of the seal’s appearance and motion but additionally a feature we know only of ourselves the possession of a mind . . (shrink)

In lieu of an abstract, here is a brief excerpt of the content:News and ViewsMark Gonnerman Click for larger view View full resolutionWhen I think of Roger Corless, I think of the bristlecone pine trees in the White Mountains of east-central California, about an hour's drive from Bishop up White Mountain Road. These trees (Pinus longaeva) are the world's oldest living beings. The senior member of the stand in Patriarch Grove, named Methuselah, is more than 4,700 years old.It is not (...) because Roger lived an especially long life—he was granted only sixty-nine-and-a-half years of calendar time—that he and these trees fuse in my mind. While Roger was an old soul from an older world, this association arises from Roger's adherence to the kind of "become who you are" eccentricity celebrated by Henry David Thoreau and other sages who remind each of us to "step to the music" of "a different drummer."When visiting the bristlecones, one is impressed by the various odd poses struck by each tree. Of course no two are alike; each holds a unique gnarly stance that says, "You are among a community of nonconformists." These trees remind us that each being is a unique expression of Nature and ought to be honored as such.Thoreau does not use the word "eccentric" in Walden, but writes of extravagance instead:I fear chiefly lest my expression not be extra- vagant enough, may not wander far enough beyond the narrow limits of my daily experience, so as to be adequate to the truth of which I have been convinced. Extra vagance! [End Page 155] it depends on how you are yarded.... I desire to speak somewhat without bounds; like a man in a waking moment, to men in their waking moments.A lover of words, as was Roger, Thoreau splits extravagance in two to highlight its root meaning: "to wander" (vagari) "outside" (extra). To learn the truth of matters requires the courage to follow one's own path, even when—especially when—it takes one beyond the pale. Only then might wanderers become convinced of those truths they know, for they have been encountered firsthand and tested, experimentally, in the realm of personal experience.When one sets about the challenging work of claiming a natural right to eccentricity, one discovers self-authenticating feedback loops that encourage further steps along an always unfolding, yet untrammeled path. It takes courage to stay in motion, for the way is often rough. People get lost—and found. One's own authentic way leads to wakefulness. This in turn enables recognition and enjoyment of other liberated beings and compassion for those who have yet to hear chanticleer crow (to stay with Thoreau) or the lion's roar (as Buddhists might say).As Mas Kodani, a Jodoshinshu minister in South-Central Los Angeles has observed, "One does not stand still looking for a path. One walks; and as one walks a path comes into being." This walk requires a balance of both confident perseverance and an ability to respond to ever-changing conditions. Lives of both the bristlecones and Roger demonstrate perseverance in spite of hostile habitats: the pines, rooted in sandstone and dolomite, hang on in a cold and dry climate at 11,200 feet; Roger made his way with difficulty in spite of challenges he faced as a gay, Buddhist-and-Christian intellectual in Durham County, North Carolina. When, after thirty years, Roger became an emeritus professor at Duke and relocated to the San Francisco Bay Area, he found himself in a much more hospitable setting.It may seem strange to draw out this comparison of Roger and those ancient White Mountain pines, but when I first met those trees in the summer of 1998, they set a standard for authenticity that came to mind whenever Roger and I interacted. His extravagant accomplishments as a teacher, scholar, and person who lived a life of genuine service to others were attained through the real work of daily spiritual practice, critical reflection, and adherence to the truths—always plural for Roger—of which he had been convinced. I'll always be grateful for his inspiring example of a human life well lived. It... (shrink)

The eastern Islamic concept of the imaginal realm, which explains how supra-sensory realities present themselves to imaginative perception, can enrich the imagination of film-philosophy. The imaginal realm, in Arabic ‘alam al-mithal, world of images, or ‘alam al-khayal, imaginative world, is part of a triadic ontology of sensible, imaginal, and intelligible realms. Diverging from roots shared with Western thought in the concept of the imaginative faculty, the Islamic imaginal realm is supra-individual and more real than matter. The imaginal realm is a (...) radically pro-image concept, affirming the importance of poetry, art, and images in motion. As developed by the Persian philosopher Sadr al-Dîn Muhammad al-Shîrâzî, known as Mullâ Sadrâ, the imaginal realm flows and intensifies, in a process philosophy we may fruitfully compare with Spinoza, Leibniz, and Whitehead. I sketch the genealogy of the imaginal realm and compare it to contemporary Western film-philosophy. I suggest how this transcendental concept can be made immanent. Finally, I draw from contemporary Muslim thinkers, such as Mohammed Arkoun, who ground a visionary collective politics in the imaginal realm. My central example, the documentary The Lebanese Rocket Society by Joana Hadjithomas and Khalil Joriege, exemplifies film's imaginal powers. (shrink)

This article situates Descartes’ physical thinking within the nexus of machine science, which rests upon different foundational piers than regular classical mechanics of a Newtonian stripe. In particular, connected cyclic processes of the sort encountered in clockwork mechanisms (and Descartes’ own vortices) become central rather than impactive collisions of any kind. Such a placement supplies a more sympathetic understanding of many of his most notorious claims: conservation of ‘quantity of motion’, relationalism with respect to space, relative rest as an (...) explanation of particle cohesion, etc. Of course, the resulting system of ideas is not perfect, but the mistakes are more subtle than usually presumed.

A version of nonstandard analysis, Internal Set Theory, has been used to provide a resolution of Zeno's paradoxes of motion. This resolution is inadequate because the application of Internal Set Theory to the paradoxes requires a model of the world that is not in accordance with either experience or intuition. A model of standard mathematics in which the ordinary real numbers are defined in terms of rational intervals does provide a formalism for understanding the paradoxes. This model suggests that (...) in discussing motion, only intervals, rather than instants, of time are meaningful. The approach presented here reconciles resolutions of the paradoxes based on considering a finite number of acts with those based on analysis of the full infinite set Zeno seems to require. The paper concludes with a brief discussion of the classical and quantum mechanics of performing an infinite number of acts in a finite time. (shrink)

Safe stair negotiation is an everyday task that children with developmental coordination disorder are commonly thought to struggle with. Yet, there is currently a paucity of research supporting these claims. We investigated the visuomotor control strategies underpinning stair negotiation in children with and without DCD by measuring kinematics, gaze behavior and state anxiety as they ascended and descended a staircase. A questionnaire was administered to determine parents' confidence in their child's ability to safely navigate stairs and their child's fall history. (...) Kinematics were measured using three-dimensional motion capture, whilst gaze was measured using mobile eye-tracking equipment. The parents of DCD children reported significantly lower confidence in their child's ability to maintain balance on the stairs and significantly more stair-related falls in the previous year compared to the parents of typically developing children. During both stair ascent and stair descent, the children with DCD took longer to ascend/descend the staircase and displayed greater handrail use, reflecting a more cautious stair negotiation strategy. No differences were observed between groups in their margin of stability, but the DCD children exhibited significantly greater variability in their foot-clearances over the step edge, which may increase the risk of a fall. For stair descent only, the DCD children reported significantly higher levels of state anxiety than the TD children and looked significantly further along the staircase during the initial entry phase, suggesting an anxiety-related response that may bias gaze toward the planning of future stepping actions over the accurate execution of an ongoing step. Taken together, our findings provide the first quantifiable evidence that safe stair negotiation is a significant challenge for children with DCD, and that this challenge is reflected by marked differences in their visuomotor control strategies and state anxiety levels. Whilst it is currently unclear whether these differences are contributing to the frequency of stair-related falls in children with DCD, our findings pave the way for future research to answer these important questions.

The study of perception and the role of the senses have recently risen to prominence in philosophy and are now a major area of study and research. However, the philosophical history of the senses remains a relatively neglected subject. Moving beyond the current philosophical canon, this outstanding collection offers a wide-ranging and diverse philosophical exploration of the senses, from the classical period to the present day. Written by a team of international contributors, it is divided into six parts: -/- Perception (...) from Non-Western Perspectives Perception in the Ancient Period Perception in the Medieval Latin/Arabic Period Perception in the Early Modern Period Perception in the Post-Kantian Period Perception in the Contemporary Period. The volume challenges conventional philosophical study of perception by covering a wide range of significant, as well as hitherto overlooked, topics, such as perceptual judgment, temporal and motion illusions, mirror and picture perception, animal senses and cross-modal integration. By investigating the history of the senses in thinkers such as Plotinus, Auriol, Berkeley and Cavendish; and considering the history of the senses in diverse philosophical traditions, including Chinese, Indian, Byzantine, Greek and Latin it brings a fresh approach to studying the history of philosophy itself. -/- Including a thorough introduction as well as introductions to each section by the editors, The Senses and the History of Philosophy is essential reading for students and researchers in the history of philosophy, perception, philosophy of mind, philosophical psychology, aesthetics and eastern and non-western philosophy. It will also be extremely useful for those in related disciplines such as psychology, religion, sociology, intellectual history and cognitive sciences. (shrink)

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

Transhumanism’s ideology is marked by a commitment to the “progress” or “perfection” of the human species through technological means. What transhumanists are after is not just therapeutic intervention or optimization of current human capabilities, but an ontological change from human to posthuman. In this article, I critique transhumanist ideology on the grounds that it fundamentally misunderstands human moral perfection as resulting from forces acting upon us (i.e., technological interventions), rather than an internal change of character. This misunderstanding reflects an impoverished (...) view of the concept of motion brought about by the rise of modern science, which entails certain ontological commitments that are not Christian in nature. I conclude transhumanism is untenable because it rests on a shaky foundation of Newtonian physics, and reduces the world to mere matter and forces. Furthermore, Christian transhumanism is especially flawed, because it is complicit in this severing of creation from its sacramental ontology, from the Being of God. (shrink)

The canonical history of mathematics suggests that the late 19th-century “arithmetization” of calculus marked a shift away from spatial-dynamic intuitions, grounding concepts in static, rigorous definitions. Instead, we argue that mathematicians, both historically and currently, rely on dynamic conceptualizations of mathematical concepts like continuity, limits, and functions. In this article, we present two studies of the role of dynamic conceptual systems in expert proof. The first is an analysis of co-speech gesture produced by mathematics graduate students while proving a theorem, (...) which reveals a reliance on dynamic conceptual resources. The second is a cognitive-historical case study of an incident in 19th-century mathematics that suggests a functional role for such dynamism in the reasoning of the renowned mathematician Augustin Cauchy. Taken together, these two studies indicate that essential concepts in calculus that have been defined entirely in abstract, static terms are nevertheless conceptualized dynamically, in both contemporary and historical practice.

This article explores a distinctive representational strategy used in stop-motion animation: the object substitution. Using as its central example a children’s TV episode in which brushes stand in for dogs, it explains how this strategy produces a complex relationship between depiction and representation. The analysis highlights the pragmatic underpinnings of various theories of pictorial and cinematic representation, arguing that, in a substitution, depicted elements constitute explicatures and represented ones implicatures. Connecting this strategy to humans’ capacity for pareidolia (seeing things (...) in other things), it contends that an object substitution achieves its effects—and reconciles its marked incongruities—by prompting viewers to pleasurably reverse-engineer the far-fetched projective imagining that motivated its use. This process, which is a form of conceptual blending, is based on relations that are neither straightforwardly iconic nor purely arbitrary. (shrink)

Through an analysis of particular sections in Proust's A la recherche du temps perdu and several pieces by Stein, I examine how their search for bodily presence fosters the development of new styles of writing as the perceptual responses of both authors override the function of the narrator. The dissertation analyzes Husserl's phenomenological ideas on motion and the body and how they are further developed in France by Merleau-Ponty. I then use their phenomenological research in order to expand upon (...) notions of physicality in both literary authors. The action of the author writing, of the body "making marks" on paper, are qualities of the physicality of writing. In Proust the visceral is a key to the mnemonic: the body 'recalls' memory to us, where we then find bodily experiences---not just images of memories, but the physical feeling of what has been and what remains physical, I demonstrate how the episodes in which Proust encounters involuntary recollection are places of physical activity; some physical presence has to occur, or some physical activity must be taking place in order for memory to become present. Stein's experiments with language are renditions of how the author makes sense of her body and the world through perception. Her language actually 'stands in' for the spoken voice of a narrator who records a world in flux rather then narrating a story. (shrink)
