Reading, even when silent and individual, is a social phenomenon and has often been studied as such. Complementary to this view, research has begun to explore how reading is embodied beyond simply being ‘wired’ in the brain. This article brings the social and embodied perspectives together in a very literal sense. Reporting a qualitative study of reading practices across student focus groups from six European countries, it identifies an underexplored factor in reading behaviour and experience. This factor is the sheer (...) physical presence, and concurrent activity, of other people in the environment where one engages in individual silent reading. The primary goal of the study was to explore the role and possible associations of a number of variables (text type, purpose, device) in selecting generic (e.g. indoors vs outdoors) as well as specific (e.g. home vs library) reading environments. Across all six samples included in the study, participants spontaneously attested to varied, and partly surprising, forms of sensitivity to company and social space in their daily efforts to align body with mind for reading. The article reports these emergent trends and discusses their potential implications for research and practice. (shrink)

What does quilting have to do with electric circuit theory? The answer is just one of the fascinating ways that best-selling popular math writer Paul Nahin illustrates the deep interplay of math and physics in the world around us in his latest book of challenging mathematical puzzles, Mrs. Perkins's Electric Quilt. With his trademark combination of intriguing mathematical problems and the historical anecdotes surrounding them, Nahin invites readers on an exciting and informative exploration of some of the many ways (...) math and physics combine to create something vastly more powerful, useful, and interesting than either is by itself. In a series of brief and largely self-contained chapters, Nahin discusses a wide range of topics in which math and physics are mutually dependent and mutually illuminating, from Newtonian gravity and Newton's laws of mechanics to ballistics, air drag, and electricity. The mathematical subjects range from algebra, trigonometry, geometry, and calculus to differential equations, Fourier series, and theoretical and Monte Carlo probability. Each chapter includes problems--some three dozen in all--that challenge readers to try their hand at applying what they have learned. Just as in his other books of mathematical puzzles, Nahin discusses the historical background of each problem, gives many examples, includes MATLAB codes, and provides complete and detailed solutions at the end. Mrs. Perkins's Electric Quilt will appeal to students interested in new math and physics applications, teachers looking for unusual examples to use in class--and anyone who enjoys popular math books.

Basic yet familiar and non-technical features of time are investigated. Two novel and detailed arguments are advanced defending the common view that 'time rolls relentlessly'. A number of hitherto neglected but important differences between spatio-temporal location and every other physical property are discussed. Also explored are the locations of circular time; the uniformity of nature, temporal positions and possible worlds, as well as the famous, unresolved problem, 'Why do we know so much more about the past than about the (...) future?'. For those who wish to delve deeper, a portion of the book consists of problems to ponder and their possible solutions. (shrink)

The Concept of Physical Law is an original and creative defense of the Regularity theory of physical law, the concept that physical laws are nothing more than descriptions of whatever universal truths happen to be instanced in nature. Professor Swartz clearly identifies and analyzes the arguments and intuitions of the opposing Necessitarian theory, and argues that the standard objection to the Regularity theory turns on a mistaken view of what Regularists mean by 'physical impossibility'; that it is impossible to construct (...) an empirical test that can distinguish between events Necessitarians call 'mere accidents' and those they call 'nornologically necessary', and that the Necessitarian theory cannot account fot human beings' free wills. Other topics in this important work include: the distinction between instrumental scientific laws and true physical laws; the distinction between failure and doom; potentialities; miracles and marvels; predictability and uniformity; statistical and numerical laws; and necessity-in-praxis.

The topic of this paper I would like to divide into two other questions than that of its title. The first question is the historical one and sounds like this: Why had Tarski chosen physical objects as truth-bearers in his original work from 1933 about truth in formalized languages?1 This historical problem may be still of importance not only from a historical point of view. Tarski’s truth-definition is still seen as one of undeniable importance for any contemporary philosophical analysis (...) of truth. (shrink)

This Element offers an overview of some of the most important debates in philosophy and physics around the topics of emergence and reduction and proposes a compatibilist view of emergence and reduction. In particular, it suggests that specific notions of emergence, which the author calls 'few-many emergence' and 'coarse-grained emergence', are compatible with 'intertheoretic reduction'. Some further issues that will be addressed concern the comparison between parts-whole emergence and few-many emergence, the emergence of effective theories, the use of (...) infinite limits, the notion of intertheoretic reduction and the explanation of universal and cooperative behavior. Although the focus will be principally on classical phase transitions and other examples from condensed matter physics, the main aim is to draw some general conclusions on the topics of emergence and reduction that can help us understand a variety of case-studies ranging from high-energy physics to astrophysics.

This is the first book in a two-volume series. The present volume introduces the basics of the conceptual foundations of quantum physics. It appeared first as a series of video lectures on the online learning platform Udemy.]There is probably no science that is as confusing as quantum theory. There's so much misleading information on the subject that for most people it is very difficult to separate science facts from pseudoscience. The goal of this book is to make you able (...) to separate facts from fiction with a comprehensive introduction to the scientific principles of a complex topic in which meaning and interpretation never cease to puzzle and surprise. An A-Z guide which is neither too advanced nor oversimplified to the weirdness and paradoxes of quantum physics explained from the first principles to modern state-of-the-art experiments and which is complete with figures and graphs that illustrate the deeper meaning of the concepts you are unlikely to find elsewhere. A guide for the autodidact or philosopher of science who is looking for general knowledge about quantum physics at intermediate level furnishing the most rigorous account that an exposition can provide and which only occasionally, in few special chapters, resorts to a mathematical level that goes no further than that of high school. It will save you a ton of time that you would have spent searching elsewhere, trying to piece together a variety of information. The author tried to span an 'arch of knowledge' without giving in to the temptation of taking an excessively one-sided account of the subject. What is this strange thing called quantum physics? What is its impact on our understanding of the world? What is ‘reality’ according to quantum physics? This book addresses these and many other questions through a step-by-step journey. The central mystery of the double-slit experiment and the wave-particle duality, the fuzzy world of Heisenberg's uncertainty principle, the weird Schrödinger's cat paradox, the 'spooky action at a distance' of quantum entanglement, the EPR paradox and much more are explained, without neglecting such main contributors as Planck, Einstein, Bohr, Feynman and others who struggled themselves to come up with the mysterious quantum realm. We also take a look at the experiments conducted in recent decades, such as the surprising "which-way" and "quantum-erasure" experiments. Some considerations on why and how quantum physics suggests a worldview based on philosophical idealism conclude this first volume. This treatise goes, at times, into technical details that demand some effort and therefore requires some basics of high school math (calculus, algebra, trigonometry, elementary statistics). However, the final payoff will be invaluable: Your knowledge of, and grasp on, the subject of the conceptual foundations of quantum physics will be deep, wide, and outstanding. Additionally, because schools, colleges, and universities teach quantum physics using a dry, mostly technical approach which furnishes only superficial insight into its foundations, this manual is recommended for all those students, physicists or philosophers of science who would like to look beyond the mere formal aspect and delve deeper into the meaning and essence of quantum mechanics. The manual is a primer that the public deserves. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hume’s Natural Philosophy and Philosophy of Physical Science by Matias SlavovKrisztián PeteMatias Slavov. Hume’s Natural Philosophy and Philosophy of Physical Science. London: Bloomsbury Academic, 2020. Pp. 216. Hardcover. ISBN 9781350087866, £95.Although the relationship between Hume and Newton is a recurring theme in the Hume literature, Matias Slavov’s book does not seek to contribute to the debate between the traditional (Hume imitated Newton’s natural philosophy) and the critical (Hume (...) intended his “science of Man” as the foundation of all other sciences) approaches regarding the nature of this relation. The book is intended to be a summary of Hume’s natural philosophy—or rather an aggregation of his comments on natural philosophical topics—pursued by exploring and analysing themes and issues that were prominent in the natural philosophy of the early modern period. In this respect it is a pioneering undertaking.Of course, Slavov does not claim in his book that Hume is a natural philosopher. “[F]irst and foremost... [h]e is not; for his main objective is to establish a new science of human nature” (1). But Slavov does claim that Hume’s natural philosophical views can be understood and valued in themselves and in the philosophical-scientific context of his time as well. The book is not a discussion of the natural philosophical dimensions of the “science of human nature,” but rather, of the natural philosophical views which are reconcilable with his main objective. In this respect, the book is not a methodological approach to Hume’s supposed natural philosophy, but a synthesis of certain elements of Hume’s philosophy that can feature in a consistent natural philosophy. Although his arguments are generally indirect and are more about what Hume seems to be committed to and what follows from his epistemological position rather than his actual positions, Slavov’s conclusions seem mostly convincing.Thus, Slavov’s point is not that the empiricist method is compatible in every detail with Newtonian mechanics, but rather that Hume seems to be committed more to a Cartesian natural philosophy. Slavov does not write about the possibility and significance of applying natural philosophical methods to moral philosophy; rather, he wants to build a complete philosophy of nature around some of Hume’s basic ideas to “fill the gap for a book on Hume’s relation to natural philosophy and philosophy of physical science” (2).The book has two “equally important aims” (ix): to shed more light onto Hume’s relationship to natural philosophy, and to demonstrate that physics and philosophy have overlapping domains. Hume was hardly concerned with physics, so Slavov’s strategy of defining natural philosophy as an overlap between physics and philosophy (chapter 1) does, to some extent, explain the lack of textual evidence in this area. The definition of natural philosophy chosen by Slavov is also intended to ensure [End Page 170] that these two goals are intertwined, since according to Slavov’s definition, natural philosophy is “a grey area between philosophy and physics” (12).Personally, I do not feel comfortable with this definition because it is not informative enough; it says that natural philosophy is more than modern physics (mathematized natural science), but it is not quite philosophy. While the first implication is very agreeable, and a number of scholars have addressed the issue, to assess the second implication, we would need to know exactly what philosophy is in this context. Perhaps the best candidate is metaphysics, even if Slavov keeps the reader somewhat in the dark on this point, despite the fact that chapter 2 is intended to establish precisely that point. Yet, the metaphysics of this period was usually (with the possible exception of Spinoza) used to support natural scientific explanations. I believe that natural philosophy is more than a “grey area” (9, 12, 22), or a contact zone; it is a complex enterprise that evolved in different forms with different emphases: Cartesian mechanics still sought to understand nature, pursuing the Aristotelian ideal of knowledge, albeit rejecting Aristotelian methods, while empiricists increasingly envisaged a more instrumentalist role for natural explanations. Newton himself was caught between the two.In this context it is intriguing whether Hume carries forward Berkeley... (shrink)

There are different groups in society who may be considered vulnerable, for example those experiencing mental or physical health issues, learning disabilities, prisoners or children. There are, however, other groups in society who may also be regarded as vulnerable, such as those who are bereaved. Vulnerability in relation to the bereaved occurs as a result of experiencing a normal life event, death or a loss. In this situation vulnerability may be transient and, depending upon the management of the bereavement, (...) generally temporary. Unlike the aforementioned groups, participants required for this type of research (bereavement, death and dying) are able to consent themselves into projects, and the capacity to do so is not an issue. Undertaking research with those who may be considered vulnerable into sensitive, emotive topics such as death and dying can create difficulties for the National Research Ethics Service (NRES), making it difficult to get approval for such studies. It appears that the ethical issues are concerned with not wishing to cause distress to participants when asked for research purposes to recollect what for some may have been emotionally challenging and traumatic events. The article offers a narrative, reflective account of the above from several perspectives: being employed as a contract researcher in a university; having experience of being an active member of a National Health Service Research Ethics Committee; and later assuming the role of full-time postgraduate (PhD) student requiring ethical approval to undertake research with what may be considered a vulnerable group involving a sensitive and emotive topic. Valuable insights from participants – their views on participation in an emotive research project and good practice in research having been explored via questionnaire – are highlighted and discussed.

"This is the book that I have been waiting for for twenty years. With exceptional clarity, Draine introduces the underlying physics and brings the basic pieces together to describe the multiphase structure of the interstellar and intergalactic medium. Combined with many useful tables and figures, this book will rapidly become a hit with students and researchers alike. It continues the fine tradition of Princeton professors writing seminal books on this topic."--Ewine van Dishoeck, Leiden University "A true tour de force, (...) providing a definitive account of the physics of interstellar matter. Written with authority and insight by a master of the subject, Bruce Draine's book will be a treasured guide for new graduate students as well as a comprehensive and rigorous reference for galactic and extragalactic researchers."--Eve Ostriker, University of Maryland "Draine has written an interstellar-medium textbook worthy of Lyman Spitzer, updated thirty years later. His coverage of atomic, molecular, radiative, thermal, and dynamical processes is excellent. Most valuable to students and professionals are the combinations of physical processes with multiwavelength observations appropriate for the modern astronomer."--J. Michael Shull, University of Colorado at Boulder "This book is a comprehensive account of the physical processes that take place in the interstellar medium and that determine its behavior. It is likely to become the bible on the subject."--Alexander Dalgarno, Harvard University "This is an outstanding text on an important topic in astrophysics. Draine carefully goes into the physical processes, providing a unifying discussion that is often missing in other treatments."--Christopher F. McKee, University of California, Berkeley. (shrink)

Indeterminacy in its various forms has been the focus of a great deal of philosophical attention in recent years. Much of this discussion has focused on the status of vague predicates such as ‘tall’, ‘bald’, and ‘heap’. It is determinately the case that a seven-foot person is tall and that a five-foot person is not tall. However, it seems difficult to pick out any determinate height at which someone becomes tall. How best to account for this phenomenon is, of course, (...) a controversial matter. For example, some (such as Sorensen (2001) and Williamson (2002)) maintain that there is a precise height at which someone becomes tall and such apparent cases of indeterminacy merely reflects our ignorance of this fact. Others maintain that there is some genuine – and not merely epistemic – indeterminacy present is such cases and offer various accounts of how best to account for it. Supervaluationists (such as Keefe (2008)), for example, claim that the indeterminacy with respect to vague terms lies in their not having a single definite extension. Rather, each term is associated with a range of possible precise extensions or precisifications such that it is semantically unsettled which is the correct extension. One precisification of ‘tall’ might allow that anyone over five feet ten inches is tall, whereas another would only allow those over six foot to qualify; but no precisification will take someone who is five foot to be tall, and someone who is seven foot will count as tall on all precisifications. Thus – while someone who is seven foot will be determinately tall and someone who is five foot determinately not so – it will be indeterminate whether someone who stands at five foot eleven inches is tall. -/- Yet, it is important to stress that putative cases of indeterminacy are not limited to vague predicates of this kind. Philosophers have invoked indeterminacy in discussions of topics as diverse as moral responsibility (Bernstein (forthcoming)), identity over time (Williams (2014)), and the status of the future (Barnes and Cameron (2009)). In this paper, we focus on two areas where discussion of various kinds of indeterminacy has been commonplace: physics and fiction. We propose a new model for understanding indeterminacy across these domains and argue that it has some notable advantages when compared to earlier accounts. Treating physics and fiction cases univocally also indicates an interesting connection between indeterminacy in these two areas. (shrink)

This 1983 book is a lively and clearly written introduction to the philosophy of natural science, organized around the central theme of scientific realism. It has two parts. 'Representing' deals with the different philosophical accounts of scientific objectivity and the reality of scientific entities. The views of Kuhn, Feyerabend, Lakatos, Putnam, van Fraassen, and others, are all considered. 'Intervening' presents the first sustained treatment of experimental science for many years and uses it to give a new direction to debates about (...) realism. Hacking illustrates how experimentation often has a life independent of theory. He argues that although the philosophical problems of scientific realism can not be resolved when put in terms of theory alone, a sound philosophy of experiment provides compelling grounds for a realistic attitude. A great many scientific examples are described in both parts of the book, which also includes lucid expositions of recent high energy physics and a remarkable chapter on the microscope in cell biology.

The topic of this book is a comparison between holism in the philosophy and language and social holism on the one hand and holism about space-time and quantum systems on the other hand. The main claim is that holism in the humanities and holism in fundamental physics come under the same substantial, general conception of holism. That is to say: arguments to the effect that the holism of the mental is unscientific or that the mental is separated from (...) the physical owing to holism are not sound. The holism of the mental fits into a world-view that bases itself on scientific realism. The addressees of this book are all those who care about our view of the world and ourselves in the spirit of an argumentative examination of different positions. No familiarity with physics is presupposed. (shrink)

Some formal issues concerning the system are examined, such as completeness, number of distinct modalities and relations to other systems. Some philosophical topics are also discussed.

The philosophy of biology should move to the center of the philosophy of science - a place it has not been accorded since the time of Mach. Physics was the paradigm of science, and its shadow falls across con temporary philosophy of biology as well, in a variety of contexts: reduction, organization and system, biochemical mechanism, and the models of law and explanation which derive from the Duhem-Popper Hempel tradition. This volume, we think, offers ample evidence of how good (...) contempo rary work in the philosophical understanding of biology has become. Marjorie Grene and Everett Mendelsohn aptly combine a deep philo sophical appreciation of conceptual issues in biology with an historical understanding of the radical changes in the science of biology since the 19th century. In this book, they present essays which probe such historical and methodological questions as reducibility, levels of organization, function and teleology, and the range of issues emerging from evolution ary theory and the species problem. In conjunction with Professor Grene's collection of essays on the philosophy of biology, The Under standing of Nature (Boston Studies in the Philosophy of Science, Vol. XXIII) and the occasional essays on these topics which we have published in other volumes (listed below), this volume contributes to bringing biology to the center of philosophical attention.

In a random process, later events seem to be loosely attached to earlier ones; in other words, a substantial or tight relationship between the two is missing. This relationship is sometimes held to be the relation of cause and effect, so that random events are not caused by what preceded them. Richard Johns, however, adopts the original stance that random events are fully caused and lack only determination by their causes; according to his causal theory of chance, the physical (...) chance of an event is the degree to which the event is determined by its causes. -/- A Theory of Physical Probability addresses an important and, until now, poorly comprehended topic: chance, or physical probability. It puts forth Johns's theory of physical chance and demonstrates the implications of this theory in various areas of physics. Johns's is a novel approach to a fundamental topic in such disciplines as philosophy, philosophy of science, and physics, and it will be widely admired by scholars for its clarity and accessibility.

The two books of Sextus Empiricus' Against the Physicists have not received much attention in their own right, as sustained and methodical specimens of sceptical philosophy. This volume redresses the balance by offering a series of in-depth studies on them, focusing in particular on their overall argumentative structure and on the various ways in which their formal features relate to their contents, showing how Sextus' procedures vary from one section to the other, and throwing new light on the way (...) he was using his sources. It follows Sextus' own division of these two books into nine successive topics, namely god, cause, wholes and parts, body, place, motion, time, number, coming-to-be and passing-away. These nine chapters are preceded by an introduction which discusses a number of general features of Sextus' scepticism and links the conclusions of this volume to some recent discussions on the scope of ancient scepticism.

The concept of contingency serves to bridge the doctrine of creation and natural science in Wolfhart Pannenberg's theology. My paper first analyzes the relation of creatio ex nihilo and creatio continua. Next I suggest three categories of contingency: global, local, and nomological. Under each category I assess Pannenberg's use of physics, cosmology, and philosophy of science. Although I agree with Pannenberg's emphasis on continuous creation and on the role of science in renewing the doctrine of creation, I argue for (...) a shift in the discussion from Pannenberg's topics to others, such as the anthropic principle, quantum physics, and thermodynamics.

In lieu of an abstract, here is a brief excerpt of the content:The De Auxiliis Controversy, Molinism, and Physical Premotion:The Christological Implications*Pachomius Walker O.P.From 1582 until 1607, the de Auxiliis controversy consumed much of the attention of Dominicans, Jesuits, and the Papacy.1 The controversy began in 1582 at Salamanca when a Scholastic debate entertained the question of [End Page 607] how Christ's sacrifice was both free and meritorious.2 The Jesuit, Prudencio de Montemayor, claimed that if Christ had been commanded to (...) lay down his life and be crucified, then his action was not free and, therefore, not meritorious.3 The Dominicans, on the other hand, resolved the question of Christ's merit and freedom using what would later come to be known as physical premotion.4 In a word, the de Auxiliis controversy has Christological roots. Even though the controversy quickly engaged other, related questions, a successful adjudication of these conflicting positions must have reference to the Christological truths implicated in the controversy.5 [End Page 608] The goal of this present study, therefore, is to exposit the Christological implications of the de Auxiliis controversy in an effort to reexamine the conflicting proposals about grace.Historically, in order to resolve the confusion about the God-man, the partisans of the debate needed to clarify their differing principles regarding God and man generally. As was soon apparent, however, the parties of the debate had contradictory understandings of basic philosophical principles.6 The participants in the controversy engaged other topics such as man's freedom, God's foreknowledge of future contingents, and predestination.7 It is understandable, therefore, that when Domingo Báñez († 1604), one of Montemayor's principal interlocutors, submitted his list of theses that summarized Montemayor's position, many of them dealt with questions other than those of Christ's merit.8Eventually, the controversy centered upon Luis de Molina's Concordia after its publication in 1588.9 The Concordia became the focus and [End Page 609] touch-point for the debate, since various parties aligned themselves based on their support for or condemnation of the work. The papal Congregation de Auxiliis (1594–1607), initially convoked by Pope Clement VIII, analyzed Molina's work and the positions contained therein. This, again, helped specify the debate. To keep the relevant parties focused and to make clear the lineaments of the controversy, it was helpful to have a standard text to which all parties had reference. Questions about God's grace and man's freedom were concretized through specific questions about Molina's approach to grace, God's knowledge, and predestination and whether his positions agreed with Thomas, Augustine, the Fathers of the Church, and Church councils. Hence, the Controversy de Auxiliis, which began by dealing with questions of Christology, resulted in a debate about the Molinist position as described in the Concordia.The subsequent years of the controversy have retained much of the same breadth: grace, freedom, God's foreknowledge, and predestination.10 The original impetus for the debate—Christology—can many times be overlooked or seen as a historical curiosity11 On one level, passing over the [End Page 610] Christological issues is reasonable: Molina's Concordia was first published after the lines of the debate had already been formed, and thus it is not a work of Christology. In fact, it was only in response to certain objections from Francisco Zumel that Molina included a more explicit treatment of Christ in his second edition.12 While those involved in the debate understood the details of Christ's merit to be a related and important issue, Molina's theological position was no longer seen primarily in terms of Christology.13 Even so, since the action of God in the human soul is nowhere clearer and nowhere more powerful than in the soul of Christ, any attempt to resolve these questions must take the original arena of Christology into account.14 [End Page 611]What follows is an attempt to reexamine the two proposals on grace—that of Molina and that of the Thomists on physical premotion—in Christological terms.15 The main Christological tenets at play are: (1) the fact that the hypostatic union is not of persons, but in the person; (2) that Christ...

Why does time pass and space does not? Are there just three dimensions? What is a quantum particle? Nick Huggett shows that philosophy -- armed with a power to analyze fundamental concepts and their relationship to the human experience -- has much to say about these profound questions about the universe. In Everywhere and Everywhen, Huggett charts a journey that peers into some of the oldest questions about the world, through some of the newest, such as: What shape is space? (...) Does it have an edge? What is the difference between past and future? What is time in relativity? Is time travel possible? Are there other universes? Huggett shows that answers to these profound questions are not just reserved for physics, and that philosophy can not only address but help advance our view of our deepest questions about the universe, space, and time, and their implications for humanity. His lively, accessible introduction to these topics is suitable for a general reader with no previous exposure to these profound and exciting questions. (shrink)

Space, Time, Matter, and Form collects ten of David Bostock's essays on themes from Aristotle's Physics, four of them published here for the first time. The first five papers look at issues raised in the first two books of the Physics, centred on notions of matter and form, and the idea of substance as what persists through change. They also range over other of Aristotle's scientific works, such as his biology and psychology and the account of change (...) in his De Generatione et Corruptione. The volume's remaining essays examine themes in later books of the Physics, including infinity, place, time, and continuity. Bostock argues that Aristotle's views on these topics are of real interest in their own right, independent of his notions of substance, form, and matter; they also raise some pressing problems of interpretation, which these essays seek to resolve.

The ArgumentThere can be no doubt about the moral and epistemological significance of what Shapin calls the “physical place” of the scientific laboratory. The physical place is defined by the locales, barriers, ports of entry, and lines of sight that bound the laboratory and separate it from other urban and architectural environments. Shapin's discussion of the emergence of the scientific laboratory in seventeenth-century England provides a convincing demonstration that credible knowledge is situated at an intersection between physical locales and (...) social distinctions. In this paper I take up Shapin's theme of the “siting of knowledge production,” but I give it a different treatment – one based on ethnomethodological studies of work. Without denying all that can be witnessed in the spectacle of the scientist at the bench and of the architectural habitat of the bench, I argue that the “place” of scientific work is defined by locally organizedtopical contextures. The paper describes two examples of such spatial orders – “opticism” and “digitality” – associated with distinct complexes of equipment and practice. These topical spaces might initially be viewed as “ideal” or “symbolic” spaces, but I argue that they are no less material than the “physical setting” of the laboratory; indeed, they are the physical setting.

Physical inactivity and coronavirus disease 2019 signify two pandemics with negative physical, mental, and economic consequences. Younger and older people have not reached the recommended physical activity level for years. Societal restrictions due to COVID-19 additionally reduce opportunities for physical activity, and they increase social isolation. Here, we outline how playing exergames with others at home could foster physical and mental health and promote communication and discussions on exergaming. Accordingly, we highlight the educational and social benefits of exergaming at home (...) and delineate the concept of Educational and Social Exergaming. We outline specific benefits and pitfalls of exergaming regarding its physical and nonphysical effects, including educational values of discussing exergaming experiences and related topics. Moreover, we discuss the relevance of practical guidelines for educational and social exergaming at home as well as prospects for future research. Overall, educational and social exergaming could alleviate several detrimental effects of both pandemics on the health and well-being of people of all ages. (shrink)

As is well known, the late Husserl warned against the dangers of reifying and objectifying the mathematical models that operate at the heart of our physical theories. Although Husserl’s worries were mainly directed at Galilean physics, the first aim of our paper is to show that many of his critical arguments are no less relevant today. By addressing the formalism and current interpretations of quantum theory, we illustrate how topics surrounding the mathematization of nature come to the fore (...) naturally. Our second aim is to consider the program of reconstructing quantum theory, a program that currently enjoys popularity in the field of quantum foundations. We will conclude by arguing that, seen from this vantage point, certain insights delivered by phenomenology and quantum theory regarding perspectivity are remarkably concordant. Our overall hope with this paper is to show that there is much room for mutual learning between phenomenology and modern physics. (shrink)

The notion of an individual and the related issues on individuation are topics that appear in the philosophical discussion ever since the antiquity. The idea of an individual thing is intuitively clear: an individual is something of a specific kind that is a unity, having its own identity, and being so that it is possible at least in principle to discern it from any other individual, even of similar species. But when we try to leave the intuitive realm (...) and push this idea to a logical analysis, we find a cluster of problems that are difficult to overcome within standard logico-mathematical contexts. In this work, we shall be concerned with some aspects of this intuitive concept of an individual and on some related facts about individuation taken from recent discussions that arose ever since the inception of quantum theory, pushing the discussion to a “logical” view, which in our opinion is still lacking in the usual debates on such issues. In the final part of the paper, we propose a metaphysics where the notion of identity is substituted, for some objects, by a weaker notion of indiscernibility, and we try to justify such a move. In most of the uses of the expression “quantum theory”, we shall not make explicit the distinction between the non-relativistic and the relativistic approaches, although they of course are quite different, for we think that the problems as we shall present them appear in both versions. But, as the text goes, the context will distinguish between them and these questions will become clear to the reader. (shrink)

The institutionalization of History and Philosophy of Science as a distinct field of scholarly endeavour began comparatively earl- though not always under that name - in the Australasian region. An initial lecturing appointment was made at the University of Melbourne immediately after the Second World War, in 1946, and other appoint ments followed as the subject underwent an expansion during the 1950s and 1960s similar to that which took place in other parts of the world. Today there are (...) major Departments at the University of Melbourne, the University of New South Wales and the University of Wollongong, and smaller groups active in many other parts of Australia and in New Zealand. "Australasian Studies in History and Philosophy of Science" aims to provide a distinctive publication outlet for Australian and New Zealand scholars working in the general area of history, philosophy and social studies of science. Each volume comprises a group of essays on a connected theme, edited by an Australian or a New Zealander with special expertise in that particular area. Papers address general issues, however, rather than local ones; parochial topics are avoided. Further more, though in each volume a majority of the contributors is from Australia or New Zealand, contributions from elsewhere are by no means ruled out. Quite the reverse, in fact - they are actively encour aged wherever appropriate to the balance of the volume in question. (shrink)

Steen Brock paints a cross-disciplinary picture of the philosophical and scientific background for the rise of the quantum theory. He accounts for the unity of Kantian metaphysics of Nature, the Helmholtzian principles, and the Hamiltonian methods of modern pre-quantum physics. Brock shows how Planck's vision of a generalization of classical physics implies that the original quantum mechanics of Heisenberg can be regarded as a successful attempt to maintain this modern unity of physics.However, for Niels Bohr, the unity (...) of science and metaphysics did not end in the world of physics. The development of quantum physics had general implications both for other sciences and for various philosophical issues. Brock discusses these matters with respect to recent topics within the philosophy of science and major interpretations of Bohr's ideas. The author invites the reader to follow a long andwinding route of thought which, in the end, culminates in Bohr's ideas of complementarity, culture and Spirit. (shrink)

Foundations research in physics, according to Bunge, has lagged behind its sister discipline, the foundations of mathematics. His book is an attempt to partially remedy this situation by analyzing the form and content of some basic ideas in physics and presenting some of the fundamental theories of physics in an axiomatic fashion. The heart of the book consists of axiomatizations of Classical Mechanics, Classical Field Theories, and Quantum Mechanics. Bunge does not claim to be working without predecessors. (...) While the idea of a separate discipline in the foundations of physics is rather new, the existence of material that clearly belongs to foundations research is not. This is attested to by the substantial bibliography at the end of the book. But he is ideally suited to the task of bringing this difficult material together and welding it in his own fashion into a coherent whole. His grasp of physical theory is wide-ranging and he writes with clarity and wit. In the first chapter he states his views on a number of issues in the philosophy of science: explanation, prediction, operationalism, laws, and other topics. The arguments are usually summarized very briefly, or reference is made to other books. Thus those who disagree with his philosophical presuppositions will not be convinced; but friends or foes will miss a great deal of informative material if they do not push on to the axiomatizations which follow and which are the main concern of the book. This book will undoubtedly be a source-book for future foundations research in the physical sciences.--R. H. K. (shrink)

For many physicists quantum theory contains strong conceptual difficulties, while for others the apparent conclusions about the reality of our physical world and the ways in which we discover that reality remain philosophically unacceptable. This book focuses on recent theoretical and experimental developments in the foundations of quantum physics, including topics such as the puzzles and paradoxes which appear when general relativity and quantum mechanics are combined; the emergence of classical properties from quantum mechanics; stochastic electrodynamics; EPR experiments (...) and Bell's Theorem; the consistent histories approach and the problem of datum uniqueness in quantum mechanics; non-local measurements and teleportation of quantum states; quantum non-demolition measurements in optics and matter wave properties observed by neutron, electron and atomic interferometry. Audience: This volume is intended for graduate students of physics and those interested in the foundations of quantum theory. (shrink)

This book presents a thoroughly empiricist account of physics. By providing an overview of the development of empiricism from Ockham to van Fraassen the book lays the foundation for its own version of empiricism. Empiricism for the author consists of three ideas: nominalism, i.e. dismissing second order quantification as unnecessary, epistemological naturalism, and viewing classification of things in natural kinds as a human habit not in need for any justification. The book offers views on the realism-antirealism debate as well (...) as on the individuation of theories as a thoroughly neglected aspect of underdetermination. The book next discusses a broad range of topics, including the predicates body, spatial distance and time interval, the ontology of electromagnetism, propensities, the measurement problem and other philosophical issues in quantum theory. Discussions about the direction of time and about string theory make up the final part of the book. (shrink)

A realistic study of man’s primary di­mensions and roles that breaches custo­mary bounds to the consideration of man to draw closer to the quintessence of man than ever before. Paul Weiss moves beyond the point where psychologists, psychiatrists, ethi­cists, and physiologists usually stop to make evident how man is at once pri­vate and public, with an I, a me, native rights, and responsibility, able to be and to function together with others in so­ciety and in the cosmos. He examines the (...) you we come to know as we confront other men, show­ing this to be both accountable and re­sponsible, with distinctive values and powers, maintained from within and ap­proached from without. You is con­trasted and compared with the me, what is publicly available to each alone, known and sustained by a radically private I. In opposition to contemporary thought, Weiss shows that I has a being, nature, and power of its own, able to make use of the self and mind, and to sustain the you and the me. These explorations pre­pare the way for a novel examination of different types of we—those that govern men, those with which they interplay, and those that, together with them, con­stitute the groups, societies, and states in which men live together. His final section deals with the dif­ference and relations between the they and the others in which he provides a fresh examination of the way men and their lived-in bodies both stand apart from and fit in the cosmos. In discussing these pivotal notions he extends our comprehension of such central topics as the difference between freedom and lib­erty, the nature of self-consciousness, the rights of the subhuman, the nature of the physical world, abortion, behav­iorism, mental health, biography, fic­tion, and the differences between men, animals, and things.

From Aristotle to Schrödinger: The Curiosity of Physics offers a novel introduction to the topics commonly encountered in the first two years of an undergraduate physics course, including classical mechanics, thermodynamics and statistical mechanics, electromagnetism, relativity, quantum mechanics, atomic and molecular physics, and astrophysics. The book presents physics as it evolved historically; it covers in considerable depth the development of the subject from ancient Greece to the present day. Though the emphasis is on the observations, (...) experiments, theories, and applications of physics, there are additionally short sections on the life and times of the main protagonists of physics. This book grew out of the author's long experience in giving undergraduate and graduate courses in classical physics and in quantum mechanics and its elementary applications. Although meant primarily for the student and teacher of physics, it will be of interest to other scientists, historians of science, and those who wish to know something about physics, how it started, and how it developed to its present day magnificence and sophistication.

A guide to the everyday decisions about right and wrong faced by physical scientists and research engineers. This book offers the first comprehensive guide to ethics for physical scientists and engineers who conduct research. Written by a distinguished professor of chemistry and chemical engineering, the book focuses on the everyday decisions about right and wrong faced by scientists as they do research, interact with other people, and work within society. The goal is to nurture readers' ethical intelligence so that (...) they know an ethical issue when they see one, and to give them a way to think about ethical problems. After introductions to the philosophy of ethics and the philosophy of science, the book discusses research integrity, with a unique emphasis on how scientists make mistakes and how they can avoid them. It goes on to cover personal interactions among scientists, including authorship, collaborators, predecessors, reviewers, grantees, mentors, and whistle-blowers. It considers underrepresented groups in science as an ethical issue that matters not only to those groups but also to the development of science, and it examines human participants and animal subjects. Finally, the book examines scientifically relevant social issues, including public policy, weapons research, conflicts of interest, and intellectual property. Each chapter ends with discussion questions and case studies to encourage debate and further exploration of topics. The book can be used in classes and seminars in research ethics and will be an essential reference for scientists in academia, government, and industry. (shrink)

"What is mathematics?" is a question that has been debated since antiquity. This book presents a groundbreaking and surprising answer to the question-showing through the concept of the physicalization of metamathematics how both mathematics and physics as experienced by humans can be seen to emerge from the unique underlying computational structure of the recently formulated ruliad. Written with Stephen Wolfram's characteristic expositional flair and richly illustrated with remarkable algorithmic diagrams, the book takes the reader on a unprecedented intellectual journey (...) to the center of some of the deepest questions about mathematics and its nature-and points the way to a new understanding of the foundations and future of mathematics, taking a major step beyond ideas from Plato, Kant, Hilbert, Gödel and others.

With over 150 alphabetically arranged entries about key scientists, concepts, discoveries, technological innovations, and learned institutions, the Oxford Guide to Physics and Astronomy traces the history of physics and astronomy from the Renaissance to the present. For students, teachers, historians, scientists, and readers of popular science books such as Galileo's Daughter, this guide deciphers the methods and philosophies of physics and astronomy as well as the historical periods from which they emerged. Meant to serve the lay reader (...) and the professional alike, this book can be turned to for the answer to how scientists learned to measure the speed of light, or consulted for neat, careful summaries of topics as complicated as quantum field theory and as vast as the universe. The entries, each written by a noted scholar and edited by J. L. Heilbron, Professor of History and Vice Chancellor, Emeritus, University of California, Berkeley, reflect the most up-to-date research and discuss the applications of the scientific disciplines to the wider world of religion, law, war, art and literature. No other source on these two branches of science is as informative or as inviting. Thoroughly cross-referenced and accented by dozens of black and white illustrations, the Oxford Guide to Physics and Astronomy is the source to turn to for anyone looking for a quick explanation of alchemy, x-rays and any type of matter or energy in between.

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 30.3 (2000) 106-113 [Access article in PDF] To Die With Others Alphonso Lingis One dies as one dies—as anyone, everyone dies, as all that lives dies. Do we not know that when we lie dying—when, bedridden, hospitalized, removed from our home and workplace, we no longer exercise our skills, launch initiatives, are depersonalized, and can do nothing but wait for the end in increasing passivity and prostration? Did (...) we not learn something of the death that will be our death from every death we witnessed or noticed about us? And when someone with whom we shared our life dies, do we not feel that something of ourselves has died too? In several senses of the word, we die with others. My Own Death It is strange then to see that in philosophy one's own death and the death of others have been separated. Socrates makes learning how to die the subject matter of philosophy and makes philosophy the daily practice of dying. He speaks of the relief he will feel when the opacity of his body will be broken. His last words—Crito, we owe a cock to Asclepius—say that life is the sickness for which death is the cure. Did not Socrates here in fact claim to know two things that he did not know—what death is, that is, that death is a relief; and what life is, that is, that life is sickness?Socrates had seen men die; he had committed himself to defend Athens in war, he had killed men in battle. He does not speak of how they died, nor of the relief he felt when they died.Socrates died the way he did in order to demonstrate his belief that the soul is of its own nature immortal. Heidegger, proclaiming the end of the metaphysics launched by the Platonic Socrates, makes one's own death again the central topic it had been for Socrates. Heidegger is convinced that death is not an accident that befalls a life that of its own nature would endure like inanimate things endure. He sets out to show that we die of our own nature, that our life casts itself with all its forces unto its end.Death and Nothingness Heidegger also claims to know what death is: that death is nothingness. He identifies it—it is this one thing, nothingness. Yet he also insists that my death is utterly my own. From the opening pages of Leo Tolstoy's The Death of Ivan Ilych, Heidegger draws the affirmation that witnessing the death of others is not the source of my sense of my own mortality. At the wake, I have only seen the body of another immobilized, tranquilized, but still fully, completely, there. I have not seen annihilation. But annihilation is what my death will be for me. This I sense in anxiety, that sense of being cast adrift, the environment no longer supporting me, sustaining me—and which is a premonition of being cast into nothingness.Death is ungraspable, unconfrontable; it has no front lines. Is it not too much to say that I know it is nothingness? Must we not rather say that death is the unknown? [End Page 106]I cannot say, strictly speaking, that I die, since—dying a violent death or not—I am conscious of only part of the event. And a great share of the terror I experience at the idea of death derives perhaps from this: bewilderment at remaining suspended in the middle of a seizure whose outcome I can never know because of my unconsciousness. This kind of unreality, this absurdity of death, is (without taking into account the physical suffering by which it might be accompanied) its radically terrible element, and not, as some may think ("Après moi le déluge!" "Since there's nothing after death, why are you afraid?" "What's the difference to you, since you won't be here any more?" etc....), what might make it acceptable. [Leiris 50] We do not know that death is nothingness—nothingness is not some thing one knows. But nothingness is... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:So Close and Other EssaysOn Hélène Cixous’s writingJoana Masóce n’est jamaispar l’intérieurni par le centreque je passe—Antonin Artaud, Cahiers d’Ivry, (1947–1948)At the end of the sixteenth century, the genre of the essay transformed the relationship between the subject and object of writing, since the essay emerged as a reaction against other literary forms—such as the commentary, the gloss or the treatise—in which the object of study is (...) not problematized. The gloss, the commentary, or the treatise deal with disciplines or thematic topics—astronomy, agronomy, theology, physics, history—in the proper sense, whereas the essay tends to focus on the approach to those issues. To put it differently, the essay is not strictly concerned with these issues or topics in themselves, but with the approach to them by means of writing.With Michel de Montaigne, specifically in his Essays published between 1580 and 1595, we are faced with writing where the knowledge of the object is no longer the sole center of the text. Despite being actually concerned with the Greek philosophical tradition, sixteenth-century religious wars, and, among many other topics, European colonialism in America, Montaigne’s Essays try to contest the privilege of the object, the privilege of the referent of writing, in [End Page 131] favor of its subject: the subject of writing and the writing itself, what we call in French une écriture de soi.As is well known, in his Essays Montaigne’s writing conveys neither message nor knowledge regarding things and topics, but what he calls “la continuelle mutation et branle” des êtres [“nostre estre”] et des objects [“ des objects”]: “the continual and perpetual mutation” of “beings” and “objects” (257).This epistemological crisis of the essay—abandoning the privilege of the object or theme for an emphasis on questioning the subject of writing and the modalities of the approach to the object—is explicit in the etymology of the word essay. Beyond the notion of attempt—in French, essayer means “to try,” “to attempt to do something”—essayer, from the Latin verb ex-agere, is a compound word of the verb agere, “to act,” in French agir. In Latin, the meaning of agere—“to act”—differs from facere, as agir does in French from faire, “to do”; it is in this way that these two verbs designate a different relationship between the subject and the object of the action. Although agere and facere both refer to action, the verb agere at the origin of the word essay designates an action accomplished by a subject, whereas facere is a transitive verb whose emphasis is placed on the object.While, on the one hand, facere is to be read in the register of transitivity—as is explicit in the following Latin phrases: facere litteram, “to write a letter,” or facere furtum, “to commit theft”—on the other hand, agere, although a transitive verb in Latin, underscores and anticipates the kind of intransitivity of action we will later find in Roman languages. In these Latin phrases, one can see that in Latin, at the same time that, the syntactic construction of agere requires an object, this object is not, strictly speaking, the real object produced by the verb, because in the phrases agere vitam, agere aetatem, or agere aevum, “to spend time or to live,” time is not the real object produced by the verb “to spend.” In Latin, “life,” vitam, “age,” aetatem, or “lifetime,” aevum, are not the real objects produced by the verb agere. This perhaps explains the evolution of the verb in French, or in English, where “to act” and agir have become intransitive verbs, reinforcing the idea that the essay appears to be a genre where whatever has to be done or said is not simply presented as an object.Moreover, instead of the conclusive verb facere, which designates the action as a result or an achievement—the letter is already written, or the theft is already commited—the temporality of agere, in Latin, is a durative one, as in the phrases agere vitam, aetatem, or aevum, “to live.” By its emphasis, not on the object...

Unification of natural science and social science is a centuries-old, unmitigated debate. Natural science has a chronological advantage over social science because the latter took time to include many social phenomena in its fold. History of science witnessed quite a number of efforts by social scientists to fit this discipline in a rational if not mathematical framework. On the other hand a tendency among some physicists has been observed especially since the last century to recast a number of social (...) phenomena in the mould of events taking place in physical world and governed by well-known systems and equations of physics. It necessitated the introduction of social physics as a new inter-disciplinary subject. Obviously this attempt is aimed at explaining hitherto unsolved or highly debated issues of social science. Physicists are showing special interest on problems on economics, ranging from some topics of normative economics to the movement of prices of derivatives. Statistics has been widely used in these attempts and at least two sub-disciplines of the subject, namely, stochastic process and time series analysis deserve special mention. All these research activities gave birth to another inter-disciplinary subject named as econophysics. Interestingly, global financial crisis of 2007–08 has revived the need of determination of prices of derivatives in a more accurate manner. This article adumbrates a sketch of the theoretical synthesis between physics and economics and the role played by statistics in this process. (shrink)

The idea that a serious threat to scientific realism comes from unconceived alternatives has been proposed by van Fraassen, Sklar, Stanford and Wray among others. Peter Lipton's critique of this threat from underconsideration is examined briefly in terms of its logic and its applicability to the case of space-time and particle physics. The example of space-time and particle physics indicates a generic heuristic for quantitative sciences for constructing potentially serious cases of underdetermination, involving one-parameter family of rivals T_m (...) that work as a team rather than as a single rival against default theory T_0. In important examples this new parameter has a physical meaning and makes a crucial _conceptual_ difference, shrinking the symmetry group and in some case putting gauge freedom, formal indeterminism vs. determinism, the presence of the hole argument, etc., at risk. Methodologies akin to eliminative induction or tempered subjective Bayesianism are more demonstrably reliable than the custom of attending only to "our best theory": they can lead either to a serious rivalry or to improved arguments for the favorite theory. The example of General Relativity vs. massive spin 2 gravity, a recent topic in the physics literature, is discussed. Arguably the General Relativity and philosophy literatures have ignored the most serious rival to General Relativity. (shrink)

I present philosophical reflections arising from a study of laboratory measurement methods in quantum physics. More specifically, I investigate three major methods of measuring kinetic energy, from the period during which quantum physics was developed and came to be widely accepted: magnetic deflection, electrostatic retardation, and material retardation. The historical material serves as a provocative focus at which many broader philosophical topics come together: the empirical testing of theories, the universal validity of physical laws, the interaction between (...) theoretical and experimental traditions, incommensurability, meaning and definition, realism and instrumentalism, the process of scientific change, and the unity of science. ;I begin the discussion by noting that the measurement methods in question were based on classical theory. Chapter 1 asks how the classical reasoning in measurements can be interpreted in quantum-mechanical terms, and concludes that only a "surface interpretation" is possible, since the classical methods involve many assumptions that conflict with quantum mechanics. Chapter 2 attempts to give a quantitative assessment of the inaccuracies that might result from using the "incorrect" classical theory in the design of measurement methods. Chapter 3 asks how we can know whether a measurement method is reliable, and investigates how different methods of measuring the same quantity can ground each other; this mutual grounding is also seen as a process of concept-formation. Chapter 4 argues that the customary quantum theories of measurement do not describe actual measurements well, and originate from an overly literal interpretation of the operator formalism of quantum mechanics. Chapter 5 examines how the classically reasoned measurement methods were incorporated into quantum physics; that history suggests a model of scientific development which can introduce fundamental changes while preserving much continuity with the old tradition. Chapter 6 develops a philosophical framework which allows a synthetic view of the concrete results presented in the earlier chapters: my work is an attempt to establish "conceptual coherence," creating and clarifying noncontradictory connections among the various conceptual activities that make up quantum physics.

Aristotle takes up the topic of change (or coming-to-be and ceasing-to-be) in both the Physics and De Generatione et Corruptione. He distinguishes between simple coming-to-be (substantial change), as when something comes into existence, and qualified coming-to-be (accidental change), as when an already existing thing alters, or moves, or changes in some other way. But he also maintains a persistence principle: that in every change, whether simple or qualified, there is something that persists throughout the change. I examine the (...) question of whether this principle threatens the viability of the distinction between substantial and accidental change by comparing what Aristotle has to say about it in the Physics with what he says in GC. In the process, I discuss several recent treatments of the topic as well as some conflicting views about the role, if any, of prime matter in Aristotle's account of substantial change. (shrink)

Music and noise can be considered as a collection of vibrational events which may impinge upon the body and the mind. As such they can induce beneficial or harmful bodily and psychological reactions. Much contemporary music production and consumption, however, produces sensory saturation and/or overload with sounds being manipulated in terms of spectrum and dynamic range. Such manipulation is not harmful by definition, but the manipulations may increase the potential for harm. Much research has been devoted to the risk of (...) auditory overstimulation, but the topic is still relevant as listening to music is a significant form of leisure noise exposure. Listening habits and attitudes toward loud music may even promote behaviors that could cause harm to listeners, both in a direct and indirect way. Listening to loud music, in fact, may be damaging to the cochlea (and possibly also the auditory nuclei and the auditory pathway), and may cause both temporary or permanent hearing loss. On the other hand, loud music may have benefits for us, particularly in terms of social integration and an enhanced sense of wellbeing and fun. Several questions can therefore be raised. What are the physical effects of sound as transferable and vibrational energy? Are there constraints and biases that shape and modify our reactions to the sounds? What are the perceptual and associated behavioral aspects? What are the psychological mechanisms for liking loud music? What are the social factors that contribute to increased preferences for loud music? And how can we assess the beneficial and harmful effects of sounds that are outside of the optimal range of stimulation? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 139-141 [Access article in PDF] Helen S. Lang. The Order of Nature in Aristotle's Physics: Place and the Elements. Cambridge: Cambridge University Press, 1998. Pp. xii + 324. £40. This is an unsuccessful book. Some of the reasons for its failure are complex, others are more simple. I cannot address all, but shall simply discuss the fundamental claims about four (...) large topical units—about nature, place, void and elemental motion—indicating why they are untenable.Discussing the celebrated definition of nature in Physics II.1, Lang contends that in it the verb kineisthai should be taken in the passive voice, that nature should be understood as a principle or cause of being moved and of being at rest, and not just blandly as a principle of motion and rest. Since Aristotle asserts in Book VIII of the Physics that the elements contain a passive principle of motion (255b30f), Lang's contention would mean that the elements in this respect do not differ from other natural entities. This is highly unlikely, given the systematic contrast of self-moving composite natural entities and simple, unarticulated elemental natures at 255a5-18. Lang goes so far as to assert [End Page 139] that "kineisthai is always passive, not middle (or reflexive), in both Plato and Aristotle" (42). Fortunately, we need not accept this on her word: although kineisthai can be both passive and middle, in some instances (notably in aorist and future), passive and middle forms are different. Accordingly, Lang's claim must be rejected on the basis of the very first passage she helpfully quotes as an "additional example" in n.24 on p.42: Physics VII.1 242a37f employs the middle voice future, kinesétai, and not the passive form, kinethésetai. The passage, teeming with different forms of the verb kineisthai, describes an entity which contains the principle of motion in itself, which moves naturally. This indisputably shows that Lang's contention is wrong.Lang, contrary to the well-entrenched scholarly consensus, claims that place is not the first (=innermost) extremity or first unmoved boundary of the containing body, but the extremity of the first body, i.e., of the celestial sphere. (The transposition of the qualification "first" happens in several, non-conclusive installments, see e.g. 99f, or 106f.) This transposition, however, runs counter to several of Aristotle's stipulations about place. Lang's all-encompassing extremity can only be the common (koinos) place of everything there is, whereas Aristotle is keen on finding the proper or particular (idios) place, a location which contains nothing but the entity itself (209a32-b1). The entirety of the discussion in Physics IV.4-5 attests that it is this latter place which Aristotle defines here: the first place is neither smaller, nor bigger than the thing in place (211a1f, a23-29, a31-33, etc.). Aristotle repeatedly stresses that the extremities of the contained body and its container are "in the same" (211a33f, b11f). This remark surely would be out of place about the remote extremity of the first containing body. It is also repeatedly set out that the direction of explanation is bottom-up, and not top-down, as Lang's all-encompassing universal place would require: it is by being in a particular locus that we can be said to be in (the sphere of) air, and by this in the heaven (209a33-b1, 211a23-26).Lang's proposal is not just theoretically unappealing. The traditional should not be rejected recklessly, without an attentive discussion. After all, it "apparently beg[a]n immediately with Theophrastus," as Lang rather uncannily admits (105), and it was Theophrastus, and not Lang, who studied and worked for decades with Aristotle.A key assertion of the chapter on void also rests on a grave philological blunder. Lang argues that interpreters switched from Aristotle's expression "that through which" (to di' hou) to "medium," thereby surrendering the original net of notions, in which the natural activity of the element impeded the progression of the...
