In this paper I evaluate the ICE-theory of function ascriptions to technical artefacts as proposed by Houkes and Vermaas, 2004a and Houkes and Vermaas, 2004b. This account adds non-structural concepts to functional description of artefacts, which are typically not employed by engineers when they ascribe functions to artefacts. The aim of this paper is to analyse to what extent the ICE-theory can reproduce the engineering view that artefacts have their functions in virtue of their physicochemical structure. It is shown (...) that this theory can reproduce this engineering view for components of artefacts but not for the artefacts themselves: engineers can ascribe functions to components on the basis of only the physicochemical structure of artefacts; but when engineers ascribe functions to artefacts as a whole, they have to consider explicitly the goals for which agents use artefacts and the actions that constitute this use.Keywords: Function theory; Technical artefacts; Components; Physics and chemistry; Engineering; Action theory.

The rich body of physical theories defines the foundation of our understanding of the world. Its mathematical formulation is based on classical Aristotelian logic. In the philosophy of science the ambiguities, paradoxes, and the possibility of subjective interpretations of facts have challenged binary logic, leading, among other developments, to Gotthard Günther’s theory of polycontexturality. Günther’s theory explains how observers with subjective perception can become aware of their own subjectivity and provides means to describe contradicting or even paradox observations in (...) a logically sound formalism. Here we summarize the formalism behind Günther’s theory and apply it to two well-known examples from physics where different observers operate in distinct and only locally valid logical systems. Using polycontextural logic we show how the emerging awareness of these limitations of logical systems entails the design of mathematical transformations, which then become an integral part of the theory. In our view, this approach offers a novel perspective on the structure of physical theories and, at the same time, emphasizes the relevance of the theory of polycontexturality in modern sciences.

Most "art and science" books focus on the science of perspective or the psychology of perception. Hidden Harmony does not. Instead, the book addresses the surprising common ground between physics and art from a novel and personal perspective. Viewing the two disciplines as creative processes, J. R. Leibowitz supplements existing and original research with illustrations to demonstrate that physics and art share guiding aesthetics and compositional demands and to show how each speaks meaningfully to the other. Leibowitz widens our experience (...) and understanding of both domains by exploring how concepts such as balance and re-balance, coherence and unity, and symmetry and "broken" symmetry affect and are affected by artistic vision and scientific principle. He reveals shared themes and understandings in each field and adroitly illustrates the parallels between the dabs of color and layers of images in a work of art and the particles of matter and packets of energy that compose the observable, physical world. Featuring examples of art images and complementary examples of physics concepts, this contemplative work helps us see art and physics as artists and physicists do. (shrink)

This unique book provides a self-contained conceptual and technical introduction to the theory of differential sheaves. This serves both the newcomer and the experienced researcher in undertaking a background-independent, natural and relational approach to "physical geometry". In this manner, this book is situated at the crossroads between the foundations of mathematical analysis with a view toward differential geometry and the foundations of theoretical physics with a view toward quantum mechanics and quantum gravity. The unifying thread is provided (...) by the theory of adjoint functors in category theory and the elucidation of the concepts of sheaf theory and homological algebra in relation to the description and analysis of dynamically constituted physical geometric spectrums.

When physicist Alan Sokal recently submitted an article to the postmodernist journal Social Text, the periodical's editors were happy to publish it--for here was a respected scientist offering support for the journal's view that science is a subjective, socially constructed discipline. But as Sokal himself soon revealed in Lingua Franca magazine, the essay was a spectacular hoax--filled with scientific gibberish anyone with a basic knowledge of physics should have caught--and the academic world suddenly awoke to the vast gap that (...) has opened between the scientific community and their mould-be critics. But the truth is that not only postmodern critics but Americans in general have a weak grasp on scientific principles and facts. In Connected Knowledge, physicist Alan Cromer offers a way to bridge the chasm, with a lively, lucid account of scientific thinking and a provocative new agenda for American education. Science, Cromer argues, is anything but common sense: It requires a particular habit of mind that does not come naturally. For example, something as simple as buoyancy can only be explained through Archimedes' principle--that a body in a fluid is subject to an upward force equal to the weight of fluid it displaces--yet few scientists could arrive at this ancient concept by trial and error. School children, however, are often given a ball and a tank of water, and asked to explain buoyancy any way they can. Today's de emphasis on teaching pupils necessary facts and principles, he argues, "far from empowering them, makes them slaves of their own subjective opinions." This movement in education, known as Constructivism, has close ties to postmodern critics (such as the editors of Social Text) who question the objectivity of science, and with it the existence of an objective reality. Cromer offers a ringing defense of the knowability of the world, both as an objective reality and as a finite landscape of discovery. The advance of scientific knowledge, he argues, is not unlike the mapping of the continents; at this point, we have found them all. He shows how the advent of quantum mechanics, rather than making knowledge less certain, actually offers a more precise understanding of the behavior of atoms and electrons. Turning from philosophy to education, he argues that instead of allowing students to flounder, however creatively, schools should follow a progressive curriculum that returns theoretical knowledge to the classroom. Connected Knowledge, however, goes much farther. As a discipline that insists upon connecting theory with measurable reality, physical science offers a new direction for reforming the social sciences. Cromer also shows how some of the hottest issues in public policy--including the debates over special education and group variations in I.Q., can be resolved through clear, hard headed thinking. For example, he argues for use of the G.E.D. as a national educational standard, with a new "politics of intelligence" to guide the distribution of school resources. Always forthright and articulate, Alan Cromer offers a startling new vision for integrating science, philosophy, and education. (shrink)

The new mathematical connection of De Donder’s differential entropy production with the differential changes of thermodynamic potentials (Helmholtz free energy, enthalpy, and Gibbs free energy) was obtained through the linear sequence of equations (direct, straightforward path), in which we use rigorous thermodynamic definitions of the partial molar thermodynamic properties. This new connection uses a global approach to the problem of reversibility and irreversibility, which is vital to global learners’ view and standardizes the linking procedure for thermodynamic potentials (...) (Helmholtz free energy, enthalpy, and and Gibbs free energy)—preferably to the sensing learners. It is shown that De Donder’s differential entropy production in an isolated composite system is equal to the differential change in total entropy and that De Donder’s equation agrees with Clausius’ inequality. The useful work of the irreversible process is discussed, which with the decrease of irreversibility tends towards the hypothetical maximum useful work of the reversible process. (shrink)

A connection viewed from the perspective of integration has the Bianchi identities as constraints. It is shown that the removal of these constraints admits a natural solution on manifolds endowed with a metric and teleparallelism. In the process, the equations of structure and the Bianchi identities take standard forms of field equations and conservation laws.The Levi-Civita (part of the) connection ends up as the potential for the gravity sector, where the source is geometric and tensorial and contains an (...) explicit gravitational contribution.Nonlinear field equations for the torsion result. In a “low-energy” approximation (linearity andlow energy-momentumtransfer), the postulate that only charge and velocities contribute to the source transforms these equations into the Maxwell system. Moreover, the affine geodesics become the equations of motion of special relativity with Lorentz force in the same approximation [J. G. Vargas,Found. Phys. 21, 379 (1991)]. The field equations for the torsion must then be viewed as applying to an electromagnetic/strong interaction.A classical unified theory thus arises where the underlying geometry confers their contrasting characters to Maxwell-Lorentz electrodynamics and to an Einstein's-like theory of gravity. The highly compact field equations must, however, be developed in phase-spacetime, since the connection is velocity-dependent, i.e., Finsler-like.Further opportunities for similarities with present-day physics are discussed: (a) teleparallelism allows for the formulation of the torsion sector of the theory as a flat space theory with concomitant point-dependent transformations; (b) spinors should replace Lorentz frames in their role as the subjects to which the connection refers; (c) the Dirac equation consistent with the frame bundle for a velocity-dependent metric with Lorentz signature generates a weak-like interaction in the torsion sector.

Making Sense of Inner Sense 'Terra cognita' is terra incognita. It is difficult to find someone not taken abackand fascinated by the incomprehensible but indisputable fact: there are material systems which are aware of themselves. Consciousness is self-cognizing code. During homo sapiens's relentness and often frustrated search for self-understanding various theories of consciousness have been and continue to be proposed. However, it remains unclear whether and at what level the problems of consciousness and intelligent thought can be resolved. Science's greatest (...) challenge is to answer the fundamental question: what precisely does a cognitive state amount to in physical terms? Albert Einstein insisted that the fundamental ideas of science are essentially simple and can be expressed in a language comprehensible to everyone. When one thinks about the complexities which present themselves in modern physics and even more so in the physics of life, one may wonder whether Einstein really meant what he said. Are we to consider the fundamental problem of the mind, whose understanding seems to lie outside the limits of the mind, to be essentially simple too? Knowledge is neither automatic nor universally deductive. Great new ideas are typically counterintuitive and outrageous, and connecting them by simple logical steps to existing knowledge is often a hard undertaking. The notion of a tensor was needed to provide the general theory of relativity; the notion of entropy had to be developed before we could get full insight into the laws of thermodynamics; the notice of information bit is crucial for communication theory, just as the concept of a Turing machine is instrumental in the deep understanding of a computer. To understand something, consciousness must reach an adequate intellectual level, even more so in order to understand itself. Reality is full of unending mysteries, the true explanation of which requires very technical knowledge, often involving notions not given directly to intuition. Even though the entire content and the results of this study are contained in the eight pages of the mathematical abstract, it would be unrealistic and impractical to suggest that anyone can gain full insight into the theory that presented here after just reading abstract. In our quest for knowledge we are exploring the remotest areas of the macrocosm and probing the invisible particles of the microcosm, from tiny neutrinos and strange quarks to black holes and the Big Bang. But the greatest mystery is very close to home: the greatest mystery is human consciousness. The question before us is whether the logical brain has evolved to a conceptual level where it is able to understand itself. (shrink)

The authors survey some debates about the nature and structure of physical theories and about the connections between our physical theories and naturalized metaphysics. The discussion is organized around an “ideal view” of physical theories and criticisms that can be raised against it. This view includes controversial commitments regarding the best analysis of physical modalities and intertheory relations. The authors consider the case in favor of taking laws as the primary modal notion, discussing objections (...) related to alleged violations of the laws, the apparent need to appeal to causality, and the status of probability. The “ideal view” includes a commitment that fundamental physical theories are explanatorily sufficient. The authors discuss several challenges to recovering the manifest image from fundamental physics, along with a distinct challenge to reductionism based on acknowledging the contributions of less fundamental theories in physical explanations.

Qualia epiphenomenalism is the view that qualitative properties of events, such as the raw feel of tastes or painfulness, lack causal efficacy. One common objection to qualia epiphenomenalism is the epistemic argument, which states that this loss of causal efficacy undermines our capacity to know about these epiphenomenal qualitative properties. A number of rejoinders have been offered up to insulate qualia epiphenomenalism from the epistemic argument. In this paper I consider and ultimately reject two such replies, namely, the common (...) underlying cause reply and the appeal to physical-effect epiphenomenalism.

This second volume is a continuation of the first volume’s 20th century conceptual foundations of quantum physics extending its view to the principles and research fields of the 21st century. A summary of the standard concepts, from modern advanced experimental tests of 'quantum ontology’ to the interpretations of quantum mechanics, the standard model of particle physics, and the mainstream quantum gravity theories. A state-of-the-art treatise that reports on the recent developments in quantum computing, classical and quantum information theory, the (...) black holes information paradox and the holographic principle to quantum cosmology, with some attention on contemporary themes such as the Bose-Einstein condensates as also to the more speculative areas of quantum biology and quantum consciousness. A final chapter on the connections between the quantum realm and philosophical idealism concludes this volume. Considering how the media (sometimes also physicists) present quantum theory, which focuses only on highly dubious ideas and speculations backed by no evidence or, worse, promote pseudo-scientific hypes that fall regularly in and out of fashion, this is a ‘vademecum’ for those who look for a serious introduction and deeper understanding of the 21st century quantum theory. All topics are explained with a concise but rigorous intermediate level style which may, at times, require some effort. However, you will finally acquire an unparalleled background in the conceptual foundations of quantum physics, enabling you to distinguish between the real science backed by experimental facts and mere speculative interpretations.

In contemporary literature, the fact that there is negative causation is the primary motivation for rejecting the physical connection view, and arguing for alternative accounts of causation. In this paper we insist that such a conclusion is too fast. We present two frameworks, which help the proponent of the physical connection view to resist the anti-connectionist conclusion. According to the first framework, there are positive causal claims, which co-refer with at least some negative causal (...) claims. According to the second framework, negative causal claims are generated from mapping and comparing different scenarios, which can fully be accounted for in purely positive terms. Since the positive causal claims evoked by both frameworks pose no obvious difficulties for the physical connection view, these frameworks make it possible for the connectionists to accommodate negative causal claims into their theory. Once these strategies are available, the connectionists become able to render all the arguments starting from the observation that there are negative causal claims in our causal discourse inconclusive with regard to the viability of the physical connection view.

Contrary to the widely-held view that our conscious states are necessarily private (in that only one person can ever experience them directly), in this paper I argue that it is possible for a person to directly experience the conscious states of another. This possibility removes an obstacle to thinking of conscious states as physical, since their apparent privacy makes them different from all other physical states. A separation can be made in the brain between our conscious mental (...) representations and the executive processes that manipulate them and are guided by them in planning and executing behaviour. I argue here that these executive processes are also largely responsible for producing our sense of self in the moment. Our conscious perceptual representations themselves reside primarily in the posterior portions of the brain's cortex, in the temporal and parietal lobes, while the executive processes reside primarily in the prefrontal lobes. We can imagine an experiment in which we sever the association fibers that connect the posterior regions with these prefrontal regions and, instead, connect the posterior regions to the prefrontal regions of another person. According to my hypothesis, this would produce in the latter person the direct experience of the conscious perceptual states of the first person. (shrink)

In the years spanning the first half of the 20th century Bertrand Russell wavered between two incompatible accounts of physical reality. On one account, physical objects were taken to be logical constructs of phenomenal entities, the immediate data of sense experience. Such a view roughly fits the familiar characterization of being a combination of “Hume plus mathematical logic.” This type of phenomenalism, in the empiricist tradition, contrasted starkly with a variant of scientific realism, including a realistic account (...) of causal connections as relations between universals, that Russell developed between 1912 and 1927, and which was derived from Kant’s distinction between a noumenal and a phenomenal world. My concern in this paper is with the viability of the unique form of scientific realism Russell developed, the role of universals and causal explanation in it, and criticisms that have been directed at it. I will argue that an early refutation of Russell’s realism by the mathematician M. Newman and a recent revival of that refutation by W. Demopoulos and M. Friedman ignore the critical role universals play in Russell’s scientific realism and hence fail to refute his view. I will also briefly consider a recent “anti-realist” argument that repeats Newman’s mistake: interpreting predicates in terms of extensions and not as referring to universal properties and relations.

: Some of the great physicists' belief in the existence of a connection between the aesthetical features of a theory (such as beauty and simplicity) and its truth is still one of the most intriguing issues in the aesthetics of science. In this paper I explore the philosophical credibility of a version of this thesis, focusing on the connection between the mathematical beauty and simplicity of a theory and its truth. I discuss a heuristic interpretation of this thesis, (...) attempting to clarify where the appeal of this Pythagorean view comes from and what are the arguments favoring its acceptance or rejection. Along the way, I sketch the historical context in which this heuristic interpretation gained credibility (the quantum crisis in physics in the 1920s), as well as the more general implications of this thesis for physicists' metaphysical outlook.

Are the laws of nature real? Do they belong to the world or merely reflect the way we speak about it? And if they are real, what sort of entity are they? These questions have been intensely debated by philosophers. Modern cosmology, however, has given such questions a new twist by introducing a unique perspective on physical reality, the perspective which I shall call the cosmological point of view. In this perspective, the universe as a whole presents itself (...) as a single individual entity that undergoes a radical change with time. Laws of physics, on the other hand, have both local and global significance. They characterize how things behave locally. But they also characterize the entire universe. This suggests an interesting connection between the universe as a whole and what laws of physics hold in this universe. From the cosmological point of view, these two totalities, the laws of physics and the universe, may be related. But how exactly? Are the laws “inscribed” in the fabric of the universe or do they in some sense “precede” it in the order of being? If the latter, what is a “medium,” over and above the physical universe, in which physical laws are “written”? If the former, are they but a consequence of the universe’s very existence? And if so, how could the laws of physics survive the dramatic change the physical state of the universe underwent in the course of time? (shrink)

ABSTRACT. This is an invited comment on “Physical Time Within Human Time”. The topic is the nature of time and its various representations in physical theory vs. our experience. In this Comment, I dissent from the standard formulation of the topic as involving a “Two Times Problem,” in which physical time is taken as being at odds with the human sense of a “flow of time.” I provide a brief overview of the case to be made for (...) the contrary view: namely, that physical theory is indeed consistent with a genuine temporal dynamism that takes into account the quantum level in connection with spacetime emergence, the latter being supervenient on specific quantum processes.

This is the first systematic exploration of the intriguing connections between Victorian physical sciences and the study of the controversial phenomena broadly classified as psychic, occult and paranormal. These phenomena included animal magnetism, spirit-rapping, telekinesis and telepathy. Richard Noakes shows that psychic phenomena interested far more Victorian scientists than we have previously assumed, challenging the view of these scientists as individuals clinging rigidly to a materialistic worldview. Physicists, chemists and other physical scientists studied psychic phenomena for a (...) host of scientific, philosophical, religious and emotional reasons, and many saw such investigations as exciting new extensions to their theoretical and experimental researches. While these attempted extensions were largely unsuccessful, they laid the foundations of modern day explorations of the connections between physics and psychic phenomena. This revelatory study challenges our view of the history of physics, and deepens our understanding of the relationships between science and the occult, and science and religion. (shrink)

Mass ideology is unique to modern society and rooted in early modern philosophy. Traditionally, knowledge had been viewed as resting on metaphysics. Rejecting metaphysical truth evoked questions about the source of "truth." For nineteenth-century ideologists, "truth" comes either from dominating classes in a progressively determined history or from a post-Copernican freedom of the superior man to create it. In From Physics to Politics Robert C. Trundle, Jr. uncovers the relation of modern philosophy to political ideology. And in rooting truth in (...) human nature and Nature by modal reasoning, he resolves the problem of politicized truth. Our concepts of scientific truth, logic, and necessity are essentially connected. Modern philosophy restricts our understanding of necessity to the political dreams and aspirations of Enlightenment intellectuals. As a result, these intellectuals refuse to acknowledge as factual or meaningful whatever is not intelligible within the practical goals of establishing science as a system of enlightened ideas. The effect of these ideas is that in our time metaphysical principles, speculative truths, our understanding of science, and the nature of logic have become subordinated to ideological dreams. Fascism, Nazism, Marxism, political correctness, and moral relativism are not historical aberrations but essential consequences. Trundle's work is groundbreaking and daring, and his underlying thesis demonstrates why scientific truth demands a modal defense. The defense not only integrates science, ethics, and politics, but shows how "truth" may be ascribed to moral and scientific principles in contrast to a modern philosophical tradition. Since this tradition is the origin of political ideology, it has led to an irrational politicization of truth. The book will appeal particularly to those interested in political history, histories of philosophy, the philosophy of sciences, and ethics. Robert C. Trundle, Jr. is a member of the New York Academy of Sciences and the Scientific Research Society of Sigma Xi, an affiliate scholar for Idealistic Studies, and has served as reader for University de Laval's Laval Theologique et Philosphique. His publications include over three dozen articles in Res Publica, Logique et Analyse, Thought, Philosphy in Science, and New Horizons in the Philosophy of Science. His books include Beyond Absurdity (with R. Puligandla), Ancient Greek Philosophy, and Medieval Reasoning. He is currently professor in the department of social sciences and philosophy at Northern Kentucky University. (shrink)

How are truths about physical and mental states related? Robert Kirk articulates and defends 'redescriptive physicalism'--a fresh approach to the connection between the physical and the mental, which answers the problems that mental causation has traditionally raised for other non-reductive views.

Lee and Schwarz suggest that separation is the grounded procedure underlying cleansing effects in different psychological domains. Here, we interpret L&S's account from a hierarchical view of cognition that considers the influence of physical properties and sensorimotor constraints on mental representations. This approach allows theoretical integration and generalization of L&S's account to the domain of formal quantitative reasoning.

Developments in science in the last few decades have led to doubts about the validity of the mechanical paradigm that has dominated science since the Scientific Revolution. The new views, coming from recently founded disciplines like non-equilibrium thermodynamics, chaos theory and the theory of dynamical systems, are rooted in physics. Nonetheless, much of their motivation comes from fields as diverse as weather prediction, ecology, economics, the study of traffic flow, and the growth of cities. Although Quantum Mechanics also led to (...) doubts about the validity of the mechanical paradigm, the new views reveal problems within classical physics itself. The implications of these developments for our understanding of space have been largely unexamined. But the close connection between the Newtonian view of space and the mechanical paradigm means that the demise of the mechanical paradigm will require a re-evaluation of our understanding of physical space.

James decides that the best price today on pork chops is at Supermarket S, then James makes driving motions for twenty minutes, then James’ car enters the parking lot at Supermarket S. Common sense supposes that the stages in this sequence may be causally connected, and that the pattern is commonplace: James’ belief (together with his desire for pork chops) causes bodily behavior, and the behavior causes a change in James’ whereabouts. Anyone committed to the idea that beliefs and desires (...) are states installed by evolution must, it seems, think something similar. For how can one see beliefs and desires as conferring selective advantage if not by supposing that, by causing bodily behavior in their subjects, they brought about changes in their subjects’ surroundings? Yet many, many philosophers currently think or worry that mental causation is illusory (see, e.g., Heil and Mele 1993, or Macdonald and Macdonald 1995). Any physical changes which a mental state appears to cause can be viewed as a complex event involving microparticles, and for any such complex event, many philosophers suppose, there will have been previous microphysical occurrences sufficient to cause it. Barring routine overdetermination of such complex events, the apparent causation of mental events seems to be excluded. Nor does it help to say that some salient segment of the previous microphysical event just is the mental event, differently described (Davidson 1970). For describing the previous events as microphysical seems to spotlight the very features in virtue of which they did their causal work; the mental features seem epiphenomenal (Yablo 1992b: pp. 425-36; Yablo 1992a). This paper argues that the complex physical events, which mental events seem excluded from causing, are not caused at all. For they are either accidents, in something like Aristotle’s sense (Sorabji 1980: pp. 3-25), or coincidences, in a sense which David Owens has recently sharpened (Owens 1992). (shrink)

Many people believe in the power of positive thinking (i.e., how thoughts and attitude can shape their future) yet, despite a plethora of books on this subject, no previous author has credibly explained how mere thoughts are able to tangibly influence future events. To explain the connection, Dr. Donlan presents a new paradigm of nature coupled with a viable explanation of how our right cerebral hemisphere has evolved circuitry that can tap into the hidden domain of the metaphysical. To (...) support this premise, he exposes the reader to the worlds of physics, metaphysics, brain architecture, and evolution. Donlan then introduces the many problems associated with the current model and contrasts it with a new view which remedies many of the issues facing theoretical physicists today. Important to its central theme, the book's proposed paradigm supports the remarkable notion that the future can only be created with thoughts. In the final analysis, the author brings his readers through the necessary steps to put this knowledge to work to help them (pre)ordain their own realities. (shrink)

Summarizing and extending the ideas of many authors and also of our own work, we try to show that the wave equation of the one-body problem can be transformed into a system of equations describing the motion of a deformable medium carrying charge and having permanent magnetic polarization. The wave equation and the system of transformed equations are connected by a strict one-to-one correspondence. The transformation which is not uniquely determined from a mathematical point of view can be chosen (...) so that the new variables have directphysical significance. The latter requirement permits consequently a unique choice of the mathematical possibilities. (shrink)

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment. Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

This edited volume examines aspects of the mind/consciousness that are relevant to the interpretations of quantum mechanics. In it, an international group of contributors focus on the possible connections between quantum mechanics and consciousness. They look at how consciousness can help us with quantum mechanics as well as how quantum mechanics can contribute to our understanding of consciousness. For example, what do different interpretations aimed at solving the measurement problem in quantum mechanics tell us about the nature of consciousness, such (...) as von Neumann's interpretation? Each interpretation has, associated to it, a corresponding metaphysical framework that helps us think about possible “models” of consciousness. Alternatively, what does the nature of consciousness tell us about the role of the observer and time reversibility in the measurement process? The book features 20 papers on contemporary approaches to quanta and mind. It brings together the work of scholars from different disciplines with diverse views on the connections between quanta and mind, ranging from those who are supportive of a link between consciousness and quantum physics to those who are very skeptical of such link.

Physics IV.10 (217b30–218a30) is pivotal in Aristotle’s discussion of time, preceding his own account from IV.11 onward. Aristotle presents three puzzles about the existence of time with reference to the “Now”. Modern interpretations often view this section as an aporetic prelude with Aristotle’s failure to provide explicit solutions. This paper examines Simplicius’ alternative interpretation, which draws upon the theory of proof and the syllogistic model from the Posterior Analytics. Simplicius contends that the arguments’ failure lies in their inability to (...) fit within the suitable syllogistic framework to establish a demonstrable definition of time, not in their aporetic nature. Every science has to prove the relation between (i) establishing whether X exists and (ii) showing what X is by establishing what the cause of X is. In evaluating Simplicius’ interpretation, this paper addresses two key aspects of the exegesis of IV.10: firstly, Simplicius can show why the “Now” is not part of the definition of time, and secondly, the ancient commentator underscores the close connection between the arguments in Physics IV.10 and the broader context of Aristotle’s discussion of time. Modern interpreters fail to address both of these issues. (shrink)

In what sense do the sciences explain? Or do they merely describe what is going on without answering why-questions at all. But cannot description at an appropriate ‘level’ provide all that we can reasonably ask of an explanation? Well, what do we mean by explanation anyway? What, if anything, gets left out when we provide a so-called scientific explanation? Are there limits of explanation in general, and scientific explanation, in particular? What are the criteria for a good explanation? Is it (...) possible to satisfy all the desiderata simultaneously? If not, which should we regard as paramount? What is the connection between explanation and prediction? What exactly is it that statistical explanations explain? These are some of the questions that have generated a very extensive literature in the philosophy of science. In attempting to answer them, definite views will have to be taken on related matters, such as physical laws, causality, reduction, and questions of evidence and confirmation, of theory and observation, realism versus antirealism, and the objectivity and rationality of science. I will state my own views on these matters, in the course of this essay. To argue for everything in detail and to do justice to all the alternative views, would fill a book, perhaps several books. I want to lead up fairly quickly to modern physics, and review the explanatory situation there in rather more detail. (shrink)

From a metaphysical point of view, it is important clearly to see the ontological difference between what is studied in mathematics and mathematical physics, respectively. In this respect, the paper is concerned with the vectors of classical physics. Vectors have both a scalar magnitude and a direction, and it is argued that neither conventionalism nor wholesale anti‐conventionalism holds true of either of these components of classical physical vectors. A quantification of a physical dimension requires the discovery of (...) ontological order relations among all the determinate properties of this dimension, as well as a conventional definition that connects the number one and mathematical unit vectors to determinate spatiotemporal physical entities. One might say that mathematics deals with numbers and vectors, but mathematical physics with scalar quantities and vector quantities, respectively. The International System of Units distinguishes between basic and derived scalar quantities; if a similar distinction should be introduced for the vector quantities of classical physics, then duration in directed time ought to be chosen as the basic vector quantity. The metaphysics of physical vectors is intimately connected with the metaphysics of time. From a philosophical‐historical point of view, the paper revives W. E. Johnson's distinction ‘determinates‐determinables’ and Hans Reichenbach's notion of ‘coordinative definition’. (shrink)

The late J. D. Bernal's lectures given to first-year students in physics at Birkbeck College, University of London, are presented here in their entirety, tracing the history of physics up to the end of the classical era at the end of 19th century, just before the discoveries of the subatom and relatively were made. In view of the prestige and profundity of the newer discoveries, Bernal felt that the classical era was being largely forgotten. In this book, he attributes (...) a greater relevance to the work of men from the distant past than is usually given. For instance, the idea of "atom" not only retains the language of the Greek, Democritus, who first postulated it, but there is also an absolutely unbroken connection between the atom of the Greek and that of the modern physicist. Bernal felt that the historical method would be a suitable introduction to the fundamental concepts of physics, and it is hoped that the readers of the book will be able to see something of the interplay between the theoretical and practical aspects of the subject.

The traditional view of symbol grounding seeks to connect an a priori internal representation or ‘form’ to its external referent. But such a ‘form’ is usually itself systematically composed out of more primitive parts, so this view ignores its grounding in the physics of the world. Some previous work simulating multiple talking/listening agents has effectively taken this stance, and shown how a shared discrete speech code can emerge. Taking the earlier work of Oudeyer, we have extended his model (...) to include a dispersive force intended to account broadly for a speaker’s motivation to increase auditory distinctiveness. New simulations show that vowel systems result that are more representative of the range seen in human languages. These simulations make many profound abstractions and assumptions. Relaxing these by including more physically and physiologically realistic mechanisms for talking and listening is seen as the key to replicating more complex and dynamic aspects of speech, such as consonant-vowel patterning.

CPT invariance and the spin-statistics connection are typically taken to be essential properties in relativistic quantum field theories (RQFTs), insofar as the CPT and Spin-Statistics theorems entail that any state of a physical system characterized by an RQFT must possess these properties. Moreover, in the physics literature, they are typically taken to be properties of particles. But there is a Received View among philosophers that RQFTs cannot fundamentally be about particles. This essay considers what proofs of the (...) CPT and Spin-Statistics theorems suggest about the ontology of RQFTs, and the extent to which this is compatible with the Received View. I will argue that such proofs suggest the Received View’s approach to ontology is flawed. (shrink)

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment.Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

Harvey Brown’s Physical Relativity defends a view, the dynamical perspective, on the nature of spacetime that goes beyond the familiar dichotomy of substantivalist/relationist views. A full defense of this view requires attention to the way that our use of spacetime concepts connect with the physical world. Reflection on such matters, I argue, reveals that the dynamical perspective affords the only possible view about the ontological status of spacetime, in that putative rivals fail to express anything, (...) either true or false. I conclude with remarks aimed at clarifying what is and isn’t in dispute with regards to the explanatory priority of spacetime and dynamics, at countering an objection raised by John Norton to views of this sort, and at clarifying the relation between background and effective spacetime structure.

In American Sign Language (ASL) narratives, signers map conceptualized spaces onto actual spaces around them that can reflect physical, conceptual, and metaphorical relations among entities. Because verb tenses are not attested in ASL, a question arises: How does a signer distinguish utterances about past events from utterances within a present conversational context? In narratives, the story-teller’s past-event utterances move the story along; accompanying these will often be subjective comments on the story, evaluative statements, and the like, that are geared, (...) in the present, to the conversational partner. This usage-based study looks at how the ASL signer integrates past and present spaces in a narrative and specifically, integrates the viewpoints associated with each. Blending past and present spaces, while a conceptual notion, is in ASL played out in utterance structure and also in the fact that signed language articulation takes place in a three-dimensional space upon which both the signer and addressee have embodied, perspectivized views. Past and present conceptual spaces both occupy the physical space of articulation, and so the blends are at once conceptual and perceivable. (shrink)

Using as a starting point recent and apparently incompatible conclusions by Saunders and Knox, I revisit the question of the correct spacetime setting for Newtonian physics. I argue that understood correctly, these two versions of Newtonian physics make the same claims both about the background geometry required to define the theory, and about the inertial structure of the theory. In doing so I illustrate and explore in detail the view—espoused by Knox, and also by Brown —that inertial structure is (...) defined by the dynamics governing subsystems of a larger system. This clarifies some interesting features of Newtonian physics, notably the distinction between using the theory to model subsystems of a larger whole and using it to model complete universes, and the scale-relativity of spacetime structure. _1_ Introduction _2_ Newtonian Mechanics and Galilean Spacetime _3_ Vector Relationism and Maxwellian Spacetime _4_ Recovering the Galilei Group: Dynamics of Subsystems _5_ Knox on Inertial Structure _6_ Connections on Maxwellian Spacetime _7_ Knox on Newtonian Gravity _8_ Vector Relationism and Newton–Cartan Theory _9_ Inertial Structure in Newton–Cartan Gravity _10_ Reconciling Knox and Saunders _11_ Conclusions.

In an accompanying paper (I), it is shown that the basic equations of the theory of Lorentzian connections with teleparallelism (TP) acquire standard forms of physical field equations upon removal of the constraints represented by the Bianchi identities. A classical physical theory results that supersedes general relativity and Maxwell-Lorentz electrodynamics if the connection is viewed as Finslerian. The theory also encompasses a short-range, strong, classical interaction. It has, however, an open end, since the source side of the (...) torsion field equation is not geometric.In this paper, Kaehler's partial geometrization of the Dirac equation is taken as a starting point for the development of fully geometric Dirac equations via the correspondence principle given in I. For this purpose, Kaehler's calculus (where the spinors are differential forms) is generalized so that it also applies when the torsion is not zero. The point is then made that the forms can take values in tangent Clifford algebras rather than in tensor algebras. The basic “Eigenschaft” of the Kaehler calculus also is examined from the physical perspective of dimensional analysis.Geometric Dirac equations of great structural simplicity are finally inferred from the standard Dirac equation by using the aforementioned correspondence principle. The realm of application of the Dirac theory is thus enriched in principle, though only at an abstract level at this point: the standard spinors, which are scalar-valued forms in the Kaehler version of that theory, become Clifford-valued. In addition, the geometrization of the Dirac equation implies a geometrization of the Dirac current. When this current is replaced in the field equations for the torsion, the theory of Paper I becomes fully geometric. (shrink)

Experimental work has revealed causal links between physical cleansing and various psychological variables. Empirically, how robust are they? Theoretically, how do they operate? Major prevailing accounts focus on morality or disgust, capturing a subset of cleansing effects, but cannot easily handle cleansing effects in non-moral, non-disgusting contexts. Building on grounded views on cognitive processes and known properties of mental procedures, we proposegrounded proceduresof separation as a proximate mechanism underlying cleansing effects. This account differs from prevailing accounts in terms of (...) explanatory kind, interpretive parsimony, and predictive scope. Its unique and falsifiable predictions have received empirical support: Cleansing attenuates or eliminates otherwise observed influences of prior events (1) across domains and (2) across valences. (3) Cleansing manipulations produce stronger effects the more strongly they engage sensorimotor capacities. (4) Reversing the causal arrow, motivation for cleansing is triggered more readily by negative than positive entities. (5) Conceptually similar effects extend to other physical actions of separation. On the flipside, grounded procedures ofconnectionare also observed. Together, separation and connection organize prior findings relevant to multiple perspectives (e.g., conceptual metaphor, sympathetic magic) and open up new questions. Their predictions are more generalizable than the specific mappings in conceptual metaphors, but more fine-grained than the broad assumptions of grounded cognition. This intermediate level of analysis sheds light on the interplay between mental and physical processes. (shrink)

The paper defends a dynamic view of reality which is founded on the assumption of the existence of the flow of time. This vindication makes use of a metaphysical theory of the flow of time developed by the author which is based on the notion of dynamic existence. It is shown that such a conception allows one to explain the fundamental phenomena connected with the flow of time, namely the continuous changing of the present, the endurance of things, and (...) the asymmetry of time. It is also argued that the proposed approach may be of some virtue for the empirical sciences because it explains the ubiquitous interest of scientists in the evolution of dynamic systems of different kinds, and provides us with an arrow of time which is lacking in theories describing fundamental physical interactions. The argument is advanced which aims to show that physics is unable to provide us with a theory of the flow of time and that we should look for such a theory in metaphysics. Thus, an approach to the relation between metaphysics and physics is vindicated that may help to overcome the difficulties blocking our understanding of reality as a dynamic one. (shrink)

The rising interest, in the late 20th century, in the foundations of quantum physics, a subject in which Franco Selleri has excelled, has suggested the fair question: how did it become so? The current answer says that experiments have allowed to bring into the laboratories some previous gedanken experiments, beginning with those about EPR and related to Bell’s inequalities. I want to explore an alternative view, by which there would have been, before Bell’s inequalities experimental tests, a change in (...) the views shared by physicists concerning the intellectual status of that issue. I will take three cases which will serve as the threads of our story: the connections between Bohm’s causal interpretation and Bell’s inequalities; Wigner’s ideas on the measurement problem; and finally Everett’s relative states formulation. In the end, I will discuss how those threads were gathered together by creating foundations of quantum physics as a field of research. (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.

I. Prigogine has proposed, and the writings of N. S. Krylov to some extent suggest, a novel and unorthodox solution to foundational problems in statistical mechanics. In particular, the view claims to offer new insight into two interconnected problems: understanding the role of probability in physics, and that of reconciling the irreversibility of physical processes with the temporal symmetry of dynamical theories. The approach in question advocates a conception of the state of a system which incorporates features of (...) the quantum mechanical state concept in a context, classical statistical mechanics, where quantum considerations are generally considered to be irrelevant. I examine the plausibility of this new approach by offering an analysis of the various notions of state employed in modern physics. ;In the first chapter, I analyze the conceptual connections between dynamical laws and the nature of a system's state. I argue that laws and states are correlative. In constructing dynamical theories one does not start with a fixed or pre-determined state concept. Neither is one given the laws of the theory from which the conception of state is derived. Rather, we get the law/state structure as a "package." In light of this general analysis, I next examine the notion of state employed in the quantum theory. Here I consider a variety of conceptions of quantum states and assess their ability to answer the "paradoxes" of quantum theory. I pay particular attention to the role of probability and related restrictions on the realization of certain states. The new approach to statistical mechanics proposes to exploit similar restrictions on states in order to resolve the irreversibility problem. But is this unorthodox approach viable? In the final four chapters, I offer a detailed critique of this approach, examining the plausibility of the radical reworking of the state concept. I argue that while some important progress can be made, certain old puzzles remain, and new and difficult ones arise--ones which raise serious doubts about the ultimate success of this particular approach. I conclude, however, by arguing that such radical proposals are not unmotivated; and that novel and unorthodox proposals concerning the foundations of statistical mechanics must be taken seriously.

In a letter addressed to Mercator in 1558, John Dee made an odd announcement, describing the Portuguese mathematician and cosmographer Pedro Nunes as the ‘most learned and grave man who is the sole relic and ornament and prop of the mathematical arts among us’, and appointing him his intellectual executor. This episode shows that Dee considered Nunes one of his most distinguished contemporaries, and also that some connection existed between the two men. Unfortunately not much is known about this (...) connection, and even such basic questions such as ‘What could John Dee know about this Portuguese cosmographer’s scientific work?’ or ‘When, why and where did this interest come about?’ still lack proper answers. In this paper I address this connection and examine Nunes’ influence on Dee’s mathematical work. I argue that Dee was interested in Nunes’ work as early as 1552 . I also claim that Dee was aware of Nunes’ programme for the use of mathematics in studying physical phenomena and that this may have influenced his own views on the subject. (shrink)

In Part 2, drawing on the results of Part 1, I will present my own interpretation of Leibniz’s philosophy of space and time. As regards Leibniz’s theory of geometry and space, De Risi’s excellent work appeared in 2007, so I will depend on this work. However, he does not deal with Leibniz’s view on time, and moreover, he seems to misunderstand the essential part of Leibniz’s view on time. Therefore I will begin with Richard Arthur’s paper, and J. (...) A. Cover’s improvement. Despite some valuable insights contained in their papers, I have to conclude their attempts fail in one way or another, because they disregard the order of state-transition of a monad, which is, on my view, one of the essential features of the monads. By reexamining Leibniz’s important text Initia Rerum, I arrived at the following interpretation. Since the realm of monads is timeless, the order of state-transition of a monad provides only the basis of time in phenomena. What Leibniz calls “simultaneity” should be understood as a unique 1- to-1 correspondence of the states of different monads. With this understanding, whatever is correct in Arthur’s and Cover’s interpretation can be reproduced in my interpretation. On this basis, we can introduce a metric of time based on congruence of duration. Leibniz connected time with space in Initia Rerum by means of motion, and introduced the notion of path of a moving point; thus the congruence of duration can be reduced to congruence of distance. Then, I can show both classical metric and relativistic metric can be reconstructed on the same basis, depending on the coding for phenomena. The relativistic metric can be combined with Leibniz’s idea of internal living force, suggesting a relation of mass with energy. However, since Leibniz has never shown the ground of constant speed of an inertial motion, there may be a vicious circle. In order to avoid this, we can extend the notion of path to whole situation, thus yielding a trajectory of the whole phenomenal world. Then, by applying optimality to possible paths, we may arrive at the law of motion, without vicious circle. A comparison of Leibniz’s dynamics with Barbour’s concludes Part 2. (shrink)

Cormac McCarthy’s novel The Road confronts readers with a question: what is there to live towards after apocalypse? McCarthy locates his protagonists in the aftermath of the world’s fiery destruction, dramatizing a relationship between a father and a son, who are, as McCarthy puts it, “carrying the fire.” This essay asserts that the body carrying the fire is a sacred, incandescent body that connects to and with the world and the other, unifying the human and the divine. This essay will (...) consider the body as a sacred connection in The Road. Paul Ricoeur’s hermeneutics and Julia Kristeva’s psychoanalytic approach will help to explore what is sacred. In addition, their works elucidate the body as a present site of human connection and sacredness while calling attention to what is glaringly absent yet hauntingly present in McCarthy’s text: the mother. In the aftermath of destruction, primitive, sacred connections become available through the sensual body, highlighting what is at stake in the novel: the connection of body and spirit. The essay will attempt to show that McCarthy’s rejection of a redemptive framework, or hope in an otherworldly reality, shrouds spirit in physicality symbolized by the fire carried by the body. This spirit offers another kind of hope, one based on the body’s potential to feel and connect to the other. The thought and works of Ricoeur and Kristeva will broaden a reading of McCarthy’s novel, especially as a statement about the unification of body and spirit, contributing a multidimensional view of a contemporary problem regarding what sustains life after a cataclysmic event.
