Until fairly recently a common way of doing history of science was to pick up an important strand of contemporary scientific thought and to trace its origin back to the philosophical tangle of the scientific revolution. This approach conveniently by-passed the breakdowns of once useful and pervasive theories, and neglected the long intellectual journeys along devious routes. History of science read like a success story; the pioneers who failed were neither dismissed nor excused; they were simply ignored. The historian knew (...) what he was hunting for and he was careful to limit his search to areas where his quarry was sure to be found. This method, which has been dubbed the precursor-view, stands in contrast—albeit, not in opposition—to the contextual method, which aims at a better understanding of the actual thought-processes of the early scientists. On this second view, history of science must not only account for present theories in the light of past developments, it must also assess old theories in terms of the scientist's conceptual framework, and judge them against the background of the world picture of his age. This may lead the historian down the blind alleys of the past, chasing spurious attempts at explaining the nature of physical reality, but it can clear the ground for a less anachronistic interpretation of the emergence of modern science and the actual process of discovery. History of science acts as a winnowing fork, but we cannot suppose that the discoverer himself always separated the wheat from the chaff, and we must be ever wary of equating the dream with the task.

We present a novel reductive theory of type-identity physicalism, which is inspired by the foundations of statistical mechanics as a general theory of natural kinds. We show that all the claims mounted against type-identity physicalism in the literature don’t apply to Flat Physicalism, and moreover that this reductive theory solves many of the problems faced by the various non-reductive approaches including functionalism. In particular, we show that Flat Physicalism can account for the appearance of multiple realizability in the special (...) sciences, and that it gives a novel account of the genuine autonomy of the kinds and laws in the special sciences. We further show that the thesis of genuine multiple realization, which is compatible with all forms of non-reductive approaches including functionalism, implies what we call token-dualism; namely the idea that in every token there are non-physical facts, which may either be non-physical properties or some non-physical substance. In other words, we prove that non-reductive kinds necessarily assume non-reductive tokens, i.e., token dualism. Finally, we show that all forms of non-reductive approaches including functionalism imply a literally multi-leveled structure of reality. (shrink)

This wide ranging discourse covers many disciplines of science and the human condition in an attempt to fully understand the manifestation of time. Time's Paradigm is, at its inception, a philosophical debate between the theories of 'Presentism' and 'The Block Model', beginning with a pronounced psychological analysis of 'free will' in an environment where the past and the future already exist. It lays the foundation for the argument that time is a cyclical, contained progression, rather than a meandering voyage into (...) infinity, bringing into question the validity of a commensurate 'Big Bang'. Following, the proposal widens to encompass physics. It tackles clock rates and time dilation, acausality and the nuisance of a universal clock, and demonstrates that conscious consideration creates the present moment - time's flow - separating the solid state past and future whose reality is devoid of space. Arguments relating to Quantum Physics theory, including the Uncertainty Principle and a Superposition of States, lend credibility to key areas involving cognitive awareness. It is posited that defined points in time and space prohibit progress in linear models for progression. Thus motile paradoxes can be resolved with the absence of infinities; temporal perception, it is concluded, being the result of uncertainty. Time's Paradigm takes the bold step of asking us to consider a tangible dimension of time, representing an intimate extension of our three, known spatial dimensions. Chaos theory is briefly introduced leading to the configuration of a fractal fourth dimension of time whose assumption demands only one direction of flow. Further, it asks whether our universe is expanding or contracting. It considers the simple physics of bodies contracting in a fourth dimension of time (UC), and how that marries comfortably with standard scientific models such as Special Relativity. The rate at which matter is contracting in the universe is illustrated in a reduction factor of 1.618... coinciding with Fibonacci's Ratio and countering Time Dilation. Lastly the more complex aspects of relativistic velocities are tackled together with the conundrum of Zero Velocity and The Speed of Light being attributes of the same event in Cyclical Space-Time, and ultimately, the prospect of superluminal velocities by interaction with parallel time-zones in a multi-layered block universe.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Pictures of Music Education by Estelle R. JorgensenPaul WoodfordEstelle R. Jorgensen, Pictures of Music Education. Indiana University Press, 2011Estelle Jorgensen has long been a mainstay of the philosophy of the music education community, having served as founding chair of the Philosophy of Music Education Special Research Interest Group of the National Association of Music Educators (formerly the Music Educators National Conference) and founding co-chair of the International (...) Society for the Philosophy of Music Education along with Frede V. Nielsen whose work is the focus of this special issue. She remains editor of the Philosophy of Music Education Review, one of the premiere professional journals in the field of music education, and general editor of the Indiana University Press book series Counterpoints: Music and Education, which has published several of her books, including the current one, Pictures of Music Education (2011), that is the subject of this review. Over the course of her career, she has also contributed many chapters to other leading professional books and to the success of international symposia as host and frequent keynote speaker. One could easily continue to enumerate Jorgensen’s many contributions to the profession, but owing to lack of space it will suffice to simply observe that the field of music education would not be what it is today had it not been for her leadership, mentorship, and commitment to building a community of scholars. It is thus a pleasure to have been invited to review the aforementioned book, which [End Page 209] ventures into “the ground between metaphor and model,” the tension between the figurative and literal, to define music education as fundamentally imaginative and open-ended.1Among the advantages of conceiving of the nature of music education as involving a dialectical tension between various metaphors and derived models, Jorgensen recounts, is that the former, because figurative, evocative, and overlapping, allow for the kinds and degrees of ambiguity and slippage that are necessary for the exercise of imagination leading to more open and productive conversation about ideas. Models, on the other hand, are by definition more literal and thus more subject to direct criticism because intended to represent reality in ways that can be empirically tested through application to practice. Indeed, models make systematic assessment and critique of ideas possible. As Jorgensen continues, models serve to simplify “difficult ideas in terms that can be readily grasped, studied, and tested,” which is particularly important to the credibility of the music teaching profession in the eyes of today’s politicians and the public.2 Nevertheless, and for the obvious reason that what Jorgensen refers to as metaphoric models are derived from metaphors and thus bear some similarity, their boundaries can be “fuzzy.”3 As already suggested, it is here, in the fertile ground between metaphor and model, that Jorgensen thinks the most creative and productive thinking about music education philosophy and practice can occur as scholars and teachers recognize and grapple with, and perhaps celebrate, the various tensions and paradoxes found therein. This approach is intended by her as an alternative to the either/or grand narratives that have in the past stifled conversation by reducing philosophy, research, and pedagogy to a search for “the ‘one’ … true or best way, or ‘high road’ to music education.”4 Jorgensen’s own purpose is more modest, and potentially more liberating, which is to open “other fruitful avenues for understanding the ways in which people come to know music.”5The book consists of fourteen chapters in all, each one, with the exception of the introductory and concluding ones, dedicated to a specific metaphor and its chosen derived model that has been “systematically teased out” before being analyzed for its potential strengths and weaknesses when applied to music education.6 Owing to limited space, it is not practical here to address all of the metaphors and models that Jorgensen presents for the reader’s consideration, but it behooves me to provide a short list in order to facilitate discussion of the overall aims of the book. They are: boutique and consumption; village and community; artist and apprenticeship; revolutionary and transgression; factory and production; garden and growth; therapist and healing; court and...

In a comparison of the principles of special relativity and of quantum mechanics, the former theory is marked by its relative economy and apparent explanatory simplicity. A number of theorists have thus been led to search for a small number of postulates - essentially information theoretic in nature - that would play the role in quantum mechanics that the relativity principle and the light postulate jointly play in Einstein's 1905 special relativity theory. The purpose of the present paper (...) is to resist this idea, at least in so far as it is supposed to reveal the fundamental form of the theory. It is argued that the methodology of Einstein's 1905 theory represents a victory of pragmatism over explanatory depth; and that its adoption only made sense in the context of the chaotic state state of physics at the start of the 20th century - as Einstein well knew.

Laws of mechanics, quantum mechanics, electromagnetism, gravitation and relativity are derived as “related mathematical identities” based solely on the existence of a joint probability distribution for the position and velocity of a particle moving on a Riemannian manifold. This probability formalism is necessary because continuous variables are not precisely observable. These demonstrations explain why these laws must have the forms previously discovered through experiment and empirical deduction. Indeed, the very existence of electric, magnetic and gravitational fields is predicted by these (...) purely mathematical constructions. Furthermore these constructions incorporate gravitation into special relativity theory and provide corrected definitions for coordinate time and proper time. These constructions then provide new insight into the relationship between manifold geometry and gravitation and present an alternative to Einstein’s general relativity theory. (shrink)

This paper presents a minimal formulation of nonrelativistic quantum mechanics, by which is meant a formulation which describes the theory in a succinct, self-contained, clear, unambiguous and of course correct manner. The bulk of the presentation is the so-called “microscopic theory”, applicable to any closed system S of arbitrary size N, using concepts referring to S alone, without resort to external apparatus or external agents. An example of a similar minimal microscopic theory is the standard formulation of classical mechanics, which (...) serves as the template for a minimal quantum theory. The only substantive assumption required is the replacement of the classical Euclidean phase space by Hilbert space in the quantum case, with the attendant all-important phenomenon of quantum incompatibility. Two fundamental theorems of Hilbert space, the Kochen–Specker–Bell theorem and Gleason’s theorem, then lead inevitably to the well-known Born probability rule. For both classical and quantum mechanics, questions of physical implementation and experimental verification of the predictions of the theories are the domain of the macroscopic theory, which is argued to be a special case or application of the more general microscopic theory.

We approach the physics of \emph{minimal coupling} in general relativity, demonstrating that in certain circumstances this leads to violations of the \emph{strong equivalence principle}, which states that, in general relativity, the dynamical laws of special relativity can be recovered at a point. We then assess the consequences of this result for the \emph{dynamical perspective on relativity}, finding that potential difficulties presented by such apparent violations of the strong equivalence principle can be overcome. Next, we draw upon our discussion (...) of the dynamical perspective in order to make explicit two `miracles' in the foundations of relativity theory. We close by arguing that the above results afford us insights into the nature of special relativity, and its relation to general relativity. (shrink)

Anthropology is the study of the origin of the man. It is basically concern with the concept of _Homo__ __sapiens_, and it is scientifically questioning what are human physical traits as well how do men behave and the variation among different groups of human with his social and cultural dimensions. Ontology is a subfield in traditional philosophy which is mainly focuses on the nature of being, existence or reality as such. There are some similarities and differences among these (...) two areas. However when we deeply study the philosophical basis of the anthropology it is proof that it was derived from ontology. Anthropology discusses the social and cultural world or the physical entity of human nature. Ontology focuses the invisible aspect of human nature along with the ultimate reality. Therefore, it has a metaphysical aspect of human being; this philosophical notion has in fact, contributed to the development of the subject of anthropology. The present modern day has given very little attention to this philosophical combination of ontolog y to anthropology, rendering further investigation into the philosophical roots of anthropology. This research paper seeks to evaluate the relationship between ontology and anthropology by paying attention to the ontological arguments about the concept of man and human nature within Greek and modern western thoughts, in comparing with modern anthropological arguments.

A philosophy of management that incorporates the big picture of human experience, all levels, and degrees of awareness in relationship with the world, will better develop and sustain an environment conducive to creative contributions that meet organizational goals. Quantum physics reveals the nature of reality to be connection and creativity engaged in a process of actualizing possibilities. Human beings participate in this process of actualization, as both observer-creator and experiencer of the universe through multiple domains of knowing – (...) a collaborator in Alfred North Whitehead’s panexperientialism. Whitehead’s God of process, the primordial field of creative possibilities, and the consequent nature which holds all the experiences of every actualization, supports human consciousness, as it self-actualizes by engaging and integrating the experience of external and internal events and their effects on awareness. Through understanding the participatory nature of consciousness with God and the world as experienced, deep meaning emerges for human life. Tapping into this deeper meaning through a philosophy of management that acknowledges the full human experience, including the embedded spiritual connection to the creative energy that is God, strengthens an organization’s vision, mission and contributions to a community. This brief overview traces a path toward a preliminary framework for a philosophy of management based on God and the ideas of connection, creativity and process. (shrink)

Thought experiments in the history of science display a striking asymmetry between chemistry and physics, namely that chemistry seems to lack well-known examples, whereas physics presents many famous examples. This asymmetry, I argue, is not independent data concerning the chemistry/physics distinction. The laws of chemistry such as the periodic table are incurably special, in that they make testable predictions only for a very restricted range of physical conditions in the universe which are necessarily conditioned by the contingences of (...) chemical investigation. The argument depends on how ‚thought experiment’ is construed. Here, several recent accounts of thought experiments are surveyed to help formulate what I call ‚crucial’ thought experiments. These have a historical role in helping to judge between hypotheses in physics, but are not helpful in chemistry past or present. (shrink)

In this work we present a construction of coherent states based on ”complexifier” method for a special type of one dimensional nonlinear harmonic oscillator presented by Mathews and Lakshmanan. We will show the state quantization by using coherent states, or to build the Hilbert space according to a classical phase space, is equivalent to departure from real coordinates to complex ones.

When I was an undergraduate in Oxford, we were taught economics almost as though it were a natural science. The subject matter of economics might be different from physics, but only in the way that the subject matter of chemistry or biology is different from physics. The actual results were presented to us as if they were scientific theories. So when we learned that savings equals investment, it was taught in the same tone of voice as one teaches that (...) force equals mass times acceleration. And we learned that rational entrepreneurs sell where marginal cost equals marginal revenue in the way that we once learned that bodies attract in a way that is directly proportional to the product of their mass and inversely proportional to the square of the distance between them. At no point was it ever suggested that the reality described by economic theory was dependent on human beliefs and other attitudes in a way that was totally unlike the reality described by physics or chemistry. Some years ago, when I published The Construction of Social Reality, I was aware that it had implications for the ontology of economics, but I was not aware that there had already been an important revival of the tradition of institutional economics. It would be an understatement to say that I welcome this interest in institutions; I enthusiastically support it. But I think that in the institutional literature there is still an unclarity about what exactly an institution is. What is the ontology, the mode of existence, of institutional reality? This article tries to add to this discussion. Economics as a subject matter, unlike physics or chemistry, is largely concerned with institutional facts. Facts about money and interest rates, exchange and employment, corporations and the balance of payments, form the very heart of the subject of economics. When Lionel Robbins, in a classic work, tells us that “Economics is a study of the disposal of scarce commodities,”2 he takes for granted a huge invisible institutional.... (shrink)

In The Heart of the Matter, Graham Greene’s metafictional commentary (indicated by the relentless presence of language and literature in the content of the novel) runs parallel to his commentary on the Catholic sacrament of the Eucharist. Strikingly, written language, due to its own physical reality and the way in which it is treated in the novel, takes on sacramental characteristics. Both written language and the Eucharist are physical, and both make truth present. Through his use of (...) physical texts to indicate the true nature of each character and by aligning the written word with the Eucharist, Greene offers a complex exploration of the sacramental possibilities of literature and language, ultimately contending that language itself is sacramental.

In lieu of an abstract, here is a brief excerpt of the content:If “Reality is the Best Metaphor,” It Must Be VirtualMarguerite R. Waller (bio)What is the search for the next great compelling application but a search for the human identity?—Doug Coupland, Microserfs... we can look forward to a richly textured and complex cyberspace, where we are at all times human, and can become bits of pixel dust flying through a virtual landscape.—3-D, multiuser, interactive, on-line virtual reality producer“Avatars (...) are Next,” the June 1996 issue of Wired announces on its cover, above a glossy foldout of Bill Gates in bathing trunks floating on a lemon yellow air mattress in a sensuous Hockney-blue swimming pool. “Mr. Bill goes Hollywood! Special Gatesfold Issue,” reads the caption underneath the (photomontaged) naked torso. The United States Congress’s attempt in February 1996 to conceptualize the Internet as an incitement to indecent sexual conduct (in Section 507 of the 1996 Telecommunications Act, the so-called Computer Decency Act) is clearly the lampooned subtext of this juxtaposition of sexualized body with the concept of the avatar. The antithesis of sensuous, avatars are bandwidth-conserving, virtual figures that take the place of users’ physical bodies in the three-dimensional, interactive, multiuser virtual environments that software developers in 1996 insist will be the telos of the development of the World Wide Web. The Wired cover implies that the nerd community finds Congress’s association of digital media with sex ridiculous (however flattering they may find it to be constructed as sexually dangerous). Not unusually, sexuality is being invoked by the state as a justification for extending its own reach (and the corporate interests it represents).But the sex/gender politics of Net free speech advocates are not necessarily more progressive. As feminist commentator Laura Miller argues in “Women and Children First: Gender and the Settling of the Electronic Frontier,” the metaphor of a frontier beyond the jurisdiction of Congress, deployed by opponents of federal regulation, draws upon a conventional construction of gender that threatens to reinscribe women as victims, reinforcing “the power imbalance between the sexes, with its roots in the concept of women as property, constantly under siege and requiring the vigilant protection of their male owners” [53]. The unintended consequence of this conceptualization, she worries, is that “the threat of regulation is built into the very mythos used to conceptualize the Net by its defenders” [50].My worry, therefore, embraces both sides of the debate over free speech on the Net. The skirmish between Big Brother and the software pioneers seems to be shaping up rhetorically as a classic fraternal competition “between men” (Sedgwick). We may read it as a contest between fundamentally congruent “male” subject positions, both of which incline to disempower “female” subject positions and both of which stand to increase their [End Page 90] own political and economic capital by the appearance of a conflict. The power-producing relationality at play in this turf war, however, simultaneously threatens to subvert the claims of each position to its own, independent ontology. Both parties, therefore, can be expected compulsively to deny their relational status. John Perry Barlowe insists, in his “Declaration of Independence in Cyberspace”: “Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are based on matter. There is no matter here.”It is this more subtle metaphysical issue, the occlusion of relation, implicated in but not reducible to, the constructions of sexuality and gender deployed by both Netizens and Congresspeople, that I find the most pressing issue in designs, uses, and discussions of cyberspace. I will argue that, in fact, the current wave of Internet development (both practically and discursively) is in some sense driven by a desire to make cyberspace safe for essentialist subjectivities of whatever ideological/political persuasion. I will unfold this argument in terms of a certain notion of addiction. My interest is not “cyberaddiction” per se, in the sense of individuals who spend what they or their associates consider too much time on-line, but rather the construction of cyberspace—both rhetorically and electronically—as a clean, clear realm in which we can transcend positionality while remaining (or becoming more fully) “ourselves.” I am not, that...

Common sense and philosophical tradition agree that mind makes a difference. What we do depends not only on how our bodies are put together, but also on what we think. Explaining how mind can make a difference has proved challenging, however. Some have urged that the project faces an insurmountable dilemma: either we concede that mentalistic explanations of behavior have only a pragmatic standing or we abandon our conception of the physical domain as causally autonomous. Although each option has (...) its advocates, most theorists have sought a middle way that accommodates both the common-sense view of mind and the metaphysical conviction about the physical world. This volume presents a collection of new, specially written essays by a diverse group of philosophers, each of whom is widely known for defending a particular conception of minds and their place in nature. Contributors include Robert Audi, Lynne Rudder Baker, Tyler Burge, Donald Davidson, Fred Dretske, Ted Honderich, Jennifer Hornsby, Frank Jackson, Jaegwon Kim, Brian P. McLaughlin, Ruth Garrett Millikan, H. W. Noonan, Philip Pettit, Ernest Sosa, and Robert Van Gulick. (shrink)

The difficulty about the naive realism which most people take for granted and which some empirical philosophers try to defend is that its proponents, in seeking to preserve the objective world of common sense, virtually read out of the picture the contribution of the perceiving subject and all that is involved in the relatedness of sense experience. The visual phenomena of perspective, distortion and hallucination, and the dependence of all other sense experience upon varying physiological factors in the percipient (...) make it well nigh impossible to believe that everything is just what we observe it to be; and the physicist's account of a world of electrical charges symbolized by mathematical formulae deals in conceptual terms which transcend sensual imagery. The resort to the sense-datum theory was but a desperate attempt on the part of philosophers to preserve the plain man's view of reality, though it left wholly obscure the relationship between the world of common sense experience and that of physical science, as well as positing a fantastic multiplication of entities corresponding to everything that could be observed under any circumstances.

Process physics2 is, like all physics, a model of reality. However, unlike traditional substance-based versions, process physics implements many process philosophical concepts, perhaps most notably, the notion of internal relations. It argues that the universe can best be understood in terms of selfreferential semantic information that is remarkably similar to mathematical stochastic neural networks research in biology. It argues that information patterns generate new information through causal efficacy and, ultimately, internal integration, generating self-organising patterns of relationships. These patterns or (...) relations have an intrinsic value inherent in their self-actualisation and thereby experience a subjective unity in response to influences from the totality of their past. The result is an internally related self-organising stream of experiences that provides a defining essence objectively distinguishable in abstraction and as exhibiting all the characteristics of a quantum space and quantum matter. In process physics, therefore, quantum phenomena emerge where no prior assumption regarding their existence is made or prescribed at the start. Rather, they are internally generated as an inherent feature of an experientially becoming reality, growing in size over time and thus having an observable key feature — i.e. a ‘defining essence’ — of an expanding universe. Reality itself is now understood — and modeled — as having a primitive form of self awareness. By this we mean that it has, in the process philosopher Alfred North Whitehead’s words, prehensions of other actualities as objects in terms of their ‘provocation of some special activity within the subject’.3 In more biologically complex information systems these ultimately lead to experiential integration as conscious discrimination of contrasts in prior experiences. Reality is, ultimately, not about the identification of isolated individuals through externality, but related individuals through internality. The purpose of this paper is to arrive at a point whereby we might apply these ultimate principles of reality to management. To do this, we shall start by considering Whitehead’s own renderings of management issues, before turning to the use management studies has or has not made of his work. In the light of this discussion, we shall question the principle of deconstructive postmodernism that underpins this body of work. We shall then ask whether and to what extent Whiteheadian principles might help explain organisations as ‘event fields’ 4 within which ‘persons-in-communities’5 reside. This will then allow us to consider organisations in terms of a process reinterpretation of physics. In so doing, we shall uncover a final contradiction, between Whitehead’s understanding of organisation and his principles concerning the application of metaphysics, to which we shall at least indicate a solution.

The first part of this long two-part work is a history of the development of the modern theory of the atom from Dalton to the present. The second part offers philosophical reflections on this history beginning with a discussion of epistemological implications and following that with an account of ontological implications. The author deals with familiar questions about the reality of micro-particles, complementarity, indeterminism, the role of the observer and other topics. But he also discusses topics like holism, atomic (...) order, the intelligibility of matter and others which are less commonly discussed by philosophers in connection with modern physical theories. The author, who is trained in physics as well as philosophy, has a flair for metaphysical speculation as well as wide knowledge of contemporary physical theory. He stresses the novelties of the quantum conception of matter, argues against its critics like Bohm, and sees it as presenting a radically new conception of atomic order despite its commitment to indeterminism. The views of Werner Heisenberg, who encouraged the author to write the book and who read it in manuscript, have clearly influenced the author, although they do not dominate his thinking.--R. H. K.

In lieu of an abstract, here is a brief excerpt of the content:The Paradox of Education:A ConversationHumberto R. Maturana and Bernhard PoerksenResponsibility of the TeacherPoerksen: Immanuel Kant writes in his essay Über Pädagogik that the wide field of education is governed by a fundamental paradox. On the one hand, we want free and self-determined individuals to leave our schools; on the other, we impose a syllabus on the future individuals, force them to attend schools, punish their failures, and persecute their (...) noncompliance. There is, if we follow Kant, an inescapable relationship of tension between the goals and the means of educational efforts: They contradict each other. Would you agree?Maturana: No. Education, the commentary of an observer, is the process of transformation resulting from the co-existence with adults. We become the adults we have been living with. This means: If freedom and self-determined thinking are the goals of educational activity, then we have to live together in a way that is supported by the mutual respect for the autonomy of the other. In my view, the paradox formulated by Kant does not exist at all. The way of life, the manner of living together, shapes and transforms people. If you want to teach autonomy and reflection, you cannot use force as a method but must create an open space for communal reflection and action. There must be no contradiction between goals and means.Poerksen: Surely, there must also be constraints? It must be laid down when everybody has to be present, what the task is, who the teacher is, who has authority.Maturana: Compulsion will emerge if the teachers do not succeed in presenting their material in a thrilling way and in making school an attractive place of being together. Their failure will lead to force.Poerksen: The teacher is totally responsible for everything that may happen in school. Is this not an exaggerated claim?Maturana: No. If a teacher behaves respectfully, if he does not intimidate his pupils, if he listens, encourages cooperation and reflection, then a special form of interaction will emerge. The way of living practiced by the teacher, including the goals of teaching, will be the source of profitable learning for the pupils. This also implies that three questions and tasks must be sorted out cooperatively in education. First it seems necessary to me to debate the educational ideal to be chosen—what should the future adults be like when leaving the school one day? Should they be democratically minded and responsibly acting citizens? Or are they to be authoritarian and commandeering hierarchs, lords who feel superior to everyone else? It is then necessary to anchor a way of life in the school that permits acting and thinking according to that ideal. Finally, there is the essential task of preparing the teachers for their job in such a [End Page 25] way as to do justice to the desired goals—to enable them to live what they have to achieve.Poerksen: This would mean that teaching has nothing to do with the stepwise elimination of ignorance, as is commonly thought. The transmission of knowledge is secondary. The primary requirement is a way of life that corresponds with one's ideals, a particular form of living together, out of which the material topics will arise in due course.Maturana: Exactly. The children do not learn mathematics in school; they learn how to live together with a mathematics teacher. Perhaps they will one day carry on this enjoyable and exciting kind of being together independently—and become mathematics teachers or mathematicians themselves. Teachers do not simply transmit some content; they acquaint their pupils with a way of living. In the process, the rules of arithmetic, the laws of physics, or the grammar of a language will be acquired. My claim is: Pupils learn teachers.Poerksen: What about children who systematically refuse to cooperate? What is to be done with them? The classical answer is, of course: bad marks, relegation, exclusion from the winning circles.Maturana: The so-called difficult children about whom teachers keep complaining often only struggle to be seen and accepted, while the whole world expects them to behave in a calculable manner and to adapt to strange demands.

The Phantom Table:Woolf,Fry,Russelland the Epistemology of Modernism. Cambridge and New York: Cambridge U.P., 2000. £35.00; US$49.95. In Virginia Woolf's difficult masterpiece, The Waves(1931),each of several separate interior monologues-"streams of consciousness" in the American critical idiom-is separated from the next by an interpolated "Interlude". The interior monologues are assigned co different characters, bur (...) the Interludes are rendered from no perspectiveat all, verymuch like the "Time Passes"chapter of Woolf's earlier and better known novel, Tothe Lighthouse (1927).The passive voice and the demonstrative and indefinite pronotms are essential, removing from the scene not only the characters' points of view, but the author's as well. Numbered among the consequences of the new twentieth-century technique of interior monologue, the Interludes can be accepted today as one more trick of literary "Modernism", but for Woolf it was new, and the task of preventing any of her Interludes from becoming just another report from the rypical "omniscient narrator" of Victorian fiction was one of the most demanding she ever set herself as a writer. Like her friend the Post-Impressionist critic Roger Fry, she wanted to analyze the world outside the self into its smallest sensible elements, then show human selvesasthey formed by accumulating the experience of these myriad, random, discontinuous components, and finally to recombine these components in their two kinds, selvesand sense-able things, into a meaningful whole-a work of art. Rejecting both the idealism of Bradley and the British philosophical generation of the 1890sand the naive positivist materialism coming out of the 1850s, Bertrand Russell eventually settled on an ontology most philosophers call "realist " in that it rejected the view that the world accessible to the senses was no more than a mental construct and considered it naive to assign the origin of subjectivity to matter. The material world was, Russell thought, actually external -"out there". He did think, however,that all we knew of the external world was what wassensed by the sensesand pictured by the mind. He alsoconcluded (in essayslike "The Relation of Sense-data to Physics"written in 1910-17)d1at both that world and what we knew of it was presented in very small parts, and Reviews 89 analyzable down to them, or, in other words, that both ontology and epistemology were atomized. Each mind, with its senses, occupied, he thought, one of an infinite number of occupied and unoccupied "perspectives", each of which Lmiquely focused che "sensibilia"-whatever was perceived in che external world-like a Leibnizian monad. Machemacicallogic, on which Russell set che highest store, would be able, he thought, to bring together perspectives by providing a minimal secof cruchswhich, though abscracc,were objective in che sense chaccheywere noc private and could be agreed to by all. Something similar though rougher mighc be done for chesensibilia in cheworld "ouc chere" by che science of physics. Did Virginia Woolflearn from Bertrand Russell?To a latcer-dayacademic ic sounds too urrerly improbable, for che simple reason (obvious to academics) chat anyone who has made icto the upper levelsof English literature must have chosen cheseparticular heights to scale because the trail was so blessedlyfreeof chosenasry mathematical burrs and logical reazles,and the air so filledwith che pure chatter of French phenomenologisrs, that no hiker would ever have to struggle with analytical philosophy again. Lessmetaphorically, the separation of departments of literature from those of philosophy has come so close to divorce chat few in U.S. English Departments can make head or cail of che graduate thesis that one of Russell's philosophy students wrote on F.H. Bradley, and fewer still can trace the term "objective correlative" used by thac student (who was in fact T. S. Eliot) back to an early work of Husserl.

This book was planned as a joint work by the two authors, but the death of Nogar in 1967 left Deely to carry out the original plan alone. The purpose of the book is to challenge the reader to think about the evidence for an evolving world and the impact of such a world on diverse areas of human concern. The authors have assembled nineteen articles written by fifteen different authors. Introducing each article is an essay which places it in (...) the context of the whole work. An extensive introductory essay by the authors shows that the development of evolutionary science has offered a model alternative to that presented by mathematical physics. Tracing the historical and philosophical origins of these two models, the editors suggest that the static world view going back to Aristotle is not the only conclusion which can be drawn from the great philosopher’s work. Rather, this world view depends on emphasizing his work on the apparently non-changing heavens; another picture would have emerged had more emphasis been placed on the dynamism of the living world. Unfortunately, the involved structure of this introductory essay may dissuade some readers from pondering its important insights. (shrink)

It is shown in the present paper that the transformation relating a parallel transported vector in a Weyl space to the original one is the product of a multiplicative gauge transformation and a proper orthochronous Lorentz transformation. Such a Lorentz transformation admits a spinor representation, which is obtained and used to deduce the transportation properties of a Weyl spinor, which are then expressed in terms of a composite gauge group defined as the product of a multiplicative gauge group and the (...) spinor group. These properties render a spinor amenable to its treatment as a particle coupled to a multidimensional gauge field in the framework of the Kaluza–Klein formulation extended to multidimensional gauge fields. In this framework, a fiber bundle is constructed with a horizontal, base space and a vertical, gauge space, which is a Lie group manifold, termed its structure group. For the present, the base is the Minkowski spacetime and the vertical space is the composite gauge group mentioned above. The fiber bundle is equipped with a Riemannian structure, which is used to obtain the classical description of motion of a spinor. In its classical picture, a Weyl spinor is found to behave as a spinning charged particle in translational motion. The corresponding quantum description is deduced from the Klein–Gordon equation in the Riemann spaces obtained by the methods of path-integration. This equation in the present fiber bundle reduces to the equation for a Weyl spinor, which is close to but differs somewhat from the squared Dirac equation. (shrink)

Although the number of articles on Sartre’s aesthetic is great, book-length treatments of the subject in any language are rare. In English, we have been practically limited to Eugene Kaelin’s important study of Sartre and Merleau-Ponty published ten years ago. This work by George Bauer provides a valuable complement to Kaelin’s theoretical analysis. The book consists of seven chapters and an appendix which treat of Sartre’s pronouncements on art and the artist as expressed in his novels and plays as well (...) as in his art and literary criticism, genre by genre and artist by artist. Philosophically, the most interesting portion of the book is probably the introductory chapter presenting an eleven-page synopsis of the elements of Sartrean aesthetics: the separation of prose from poetry with its attendant problem of committed literature, the work of art as imaginary object, and the aesthetic significance of Sartre’s distinction between existence and being. It is this last element which Bauer exploits as he examines Sartre’s repeated strictures against artists who confuse the being of the art object with physical being or who flee the responsibility of human existence for some "project of being." If art is not "reality" for Sartre, neither is it a legitimate means of escape. Because his evaluations involve reference to content as well as form, Sartre’s criticism has assumed a sociopolitical posture from the very start. The overall impression left by Bauer’s work is that Sartre’s art criticism involves the often inconsistent application of relatively few criteria to quite select works of the artists in question in accord with a general theory of human freedom. Despite the occasional brilliance and unfailing intelligence of the judgments so produced, Sartre’s method leaves him vulnerable to the charge of unfairness and inadequacy. Readers desiring an extended analysis of Sartre’s general aesthetic theory will still find Kaelin’s book indispensable. Physically, this is a most attractive volume, featuring thirty-two prints as well as a Calder cartoon of Sartre on its cover.—T. R. F. (shrink)

In A Dentist and a Gentleman the sociologist Tracey Adams retells a familiar professionalization story, this time about elite dental practitioners in nineteenth‐century Ontario who launched a status‐enhancement project to reshape their self‐ and public image into “professional gentlemen” and establish monopoly control over dental practice. Dentists secured legislation in 1868 giving them authority to set entrance requirements, test and license practitioners, and establish a college. In subsequent decades they campaigned against those they called “quacks” who practiced without a license, (...) advertised, charged low fees, maintained dirty offices, misled patients about pain, or brought the gentlemanly status of dentistry into disrepute.Despite early resistance, the project had mostly succeeded by 1918, as dentists skillfully linked their expertise to emerging public health concerns and a professional image subtly reoriented toward an ideal of public service. By 1900 dental rhetoric was warning Canadians of an impending crisis of tooth decay and dental disease that would bring physical deterioration and mass feeblemindedness in its wake. Racial degeneracy, dentists warned, began in the mouth; the advance of civilization produced too much soft food and sugar, too little chewing, and too many high‐strung and overindulgent mothers. Only dentists, as “sentinels at the portal of the alimentary tract” , could stand against this threat to Anglo‐Saxon civilization. Rhetoric like this, combined with doses of guilt heaped on mothers, teachers, school boards, and public health agencies, resulted by 1915 in regular dental inspections of schoolchildren, free dental clinics, and the creation of the army dental corps.Dentistry brought unique twists to this familiar professionalization story. Prior to 1860 dentistry was an especially low‐status craft, associated with uneducated, itinerant tooth‐drawers or craftsmen like blacksmiths and gunsmiths . Professionalizing dentists therefore felt a special imperative to recast themselves as “gentlemen”; this image also reassured the upper‐middle‐class women who were dentists' main clientele. Unexpectedly, as Adams shows in an intriguing analysis, dentists benefited from an invaluable social alliance with physicians, who offered no opposition of the sort they raised against other rival groups of healers to dentists' professional aspirations.The study deals extensively with how gender shapes professions. Dentistry's professionalization, Adams insists, involved the adoption of a new ideal of personal masculinity, as seen in admonitions to dentists to establish firm, courteous, expert authority over their clients and in dentists' efforts to shape the imagined persona of the ideal dental assistant as uniquely female and wifelike. This masculine crafting of the profession notwithstanding, Ontario dentists evinced less overt opposition to women aspirants than did doctors or lawyers. Nevertheless, the proportion of female practitioners was much lower in dentistry than in medicine or law and remains substantially lower today. Adams brings considerable insight to her discussion of these facts and their causes, and she presents useful comparisons among the professions.This study has a few limitations. Perhaps because the author's sources are mainly professional journals, her account mostly mirrors the outlook of the professionalizing elite and her prose occasionally adopts their moralizing and improving tone. Regrettably, the book deals scarcely at all with what dentists actually did. One learns little about how changing scientific and medical ideas affected dentists' work, how dentists utilized anaesthesia and coped with the problem of pain, and what controversies over diagnostics and treatment animated the profession or about dentists' training and income. This is a history of dentistry's professionalization, not of dental medicine per se. But Isis readers impressed by this solid and modest study will hope that a history of dental practice will be Tracey Adams's next project. (shrink)

Consistent materialists are almost bound to suggest that ‘conscious experience’, if it exists at all, is no more than epiphenomenal. A correct understanding of the real requires that everything we do and say is no more than a product of whatever processes are best described by physics, without any privileged place, person, time or scale of action. Consciousness is a myth, or at least a figment. Plotinus was no materialist: for him, it is Soul and Intellect that are more real (...) than the phenomena we misdescribe as material. Nor does he suppose that consciousness depends on language (as Stoics and modern materialists have sometimes said): wordless experience is actually superior. And much of what counts towards our present consciousness is to be discarded. It is betternotto remember most of what now seems more significant to us; better to discard images; better that the intellect be ‘drunk’ than ‘sober’, losing any sense of separation between subject and object. The goal of the Plotinian intellectual is to join ‘the dance of immortal love’, but it is a mark of the good dancer that she is not conscious of what she does. There is therefore a strange confluence between Plotinus and modern materialists:ourexperience at least is transitory, deceitful, epiphenomenal, and ‘reality’ is to be encountered when we have shed our illusions.

In this paper, we re-examine a series of gedanken welcher Weg (WW) experiments introduced by Scully, Englert and Walther that contain the essential ideas underlying the quantum eraser. For this purpose we use the Bohm model which gives a sharp picture of the behaviour of the atoms involved in these experiments. This model supports the thesis that interference disappears in such WW experiments, even though the centre of mass wave function remains coherent throughout the experiment. It also shows exactly (...) what it means to say ‘that the interference can be restored by manipulating the WW detectors long after the atoms have passed’. It does not support Wheeler’s notion that ‘the past is undefined and undefinable without the observation (in the present)’. (shrink)

The pedagogic intention of this unusual book is to present a unified picture of the whole of Plato, taking his metaphysical position with a seriousness rare in Anglo-American Plato-scholarship. The substance of the work depends on three claims. First, eide are not postulated or secondary entities, alongside sensibles. For Findlay, it is the eide which are ultimately real; the proper characterization of the being of sensibles is as "parasitic" on the original entities, the eide. There is a gradation of (...) being, and eide rather than sensibles are the measure. Beneath the full reality of the eide lies the partial or relative non-being of sensibles, and then the absolute non-being which Findlay identifies with the chora of Timaeus 52b. Above the reality of eide are their principles: the One, and the Dyad. Second, Findlay claims that even from the earliest dialogues in which the eide are suggested, Plato envisioned but did not complete a program of mathematizing the eide, and of using this mathematicization to account for the relation between the principles of eide and the sensible instantiations of the eide. This program, Findlay says, had to do with establishing ratios between eide, but is not described further than this. Third, as an exegetic requirement, Findlay has stated that this Prinzipienlehre is fully consistent with, and elucidated and supported by, the reports of Aristotle and of his commentators, especially Syrianus. This is, of course, the "unwritten doctrine" to which the title of the book alludes. Perhaps the greatest value of the work is that it challenges the prevalent interpretative opinion, supported by Professor Cherniss’ "almost superhuman scholarship," that the Aristotelian reports are distortions of Plato, and thus to be discounted, while the "real Plato" is in the dialogues alone.

The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the past decade have shown that the dynamical evolution of a system can be treated in a manifestly covariant way, in terms of the solution of a system of canonical Hamilton type equations, by considering the space-time coordinates and momenta ofevents as its fundamental description. The evolution of the events, as functions of (...) a universal invariant world, or historical, time, traces out the world lines that represent the phenomena (e.g., particles) which are observed in the laboratory. The positions in time of each of the events, i.e., the time of their potential detection, are, in this framework, controlled by this universal parameter τ, the time at which they are generated (and may proceed in the positive or negative sense). We find that the notion of thestate of a system requires generalization; at any given τ, it involves information about the system at timest(τ) ≠ τ. The correlation of what may be measured att(τ) with what is generated at τ is necessarily quite rigid, and is related covariantly to the spacelike correlations found in interference experiments. We find, furthermore, that interaction with Maxwell electromagnetism leads back to a static picture of the world, with no real evolution. As a consequence of this result, and the requirement of gauge invariance for the quantum mechanical evolution equation, we conclude that electromagnetism is described by a pre-Maxwell field, whose τ-integral (or asymptotic behavior as τ → ∞) may be identified with the Maxwell field. We therefore consider the world of events in space time, interacting through τ-dependent pre-Maxwell fields, as far as electrodynamics is concerned, as the objective dynamical reality. Our perception of the world, through laboratory detectors and our eyes, are based onintegration over τ over intervals sufficiently large to obtain an aposteriori description of the phenomena which coincides with the Maxwell theory. Fundamental notions, such as the conservation of charge, rest on this construction. The decomposition of the common notion of time into two essentially different aspects, one associated with an unvarying flow, and the second with direct observation subject to dynamical modification, has profound philosophical consequences, of which we are able to explore here only a few.

The present work sets out to discuss in three main steps the roots of the indeterministic paradigm for quantum mechanics as against a causal explanation of reality. The first step is to present the fundamental role played by non-local Fourier analysis in the Copenhagen paradigm. The second is to present wavelet local analysis, a recent formalism that will perhaps allow the development of a new causal paradigm for physics. The third is to present the Heisenberg-Bohr uncertainty relations as a (...) direct mathematical consequence of Fourier non-local analysis. Finally, experimental evidence violating these relations is presented. These results imply that the indeterministic approach has reached its limits. However, they can be explained within a causal framework allowing a more general mathematical formulation for uncertainty relations. (shrink)

The first part of this long two-part work is a history of the development of the modern theory of the atom from Dalton to the present. The second part offers philosophical reflections on this history beginning with a discussion of epistemological implications and following that with an account of ontological implications. The author deals with familiar questions about the reality of micro-particles, complementarity, indeterminism, the role of the observer and other topics. But he also discusses topics like holism, atomic (...) order, the intelligibility of matter and others which are less commonly discussed by philosophers in connection with modern physical theories. The author, who is trained in physics as well as philosophy, has a flair for metaphysical speculation as well as wide knowledge of contemporary physical theory. He stresses the novelties of the quantum conception of matter, argues against its critics like Bohm, and sees it as presenting a radically new conception of atomic order despite its commitment to indeterminism. The views of Werner Heisenberg, who encouraged the author to write the book and who read it in manuscript, have clearly influenced the author, although they do not dominate his thinking.--R. H. K.

This volume presents human rights in action, focussing on their effectiveness as legal tools designed to benefit human beings. By combining conceptual analysis with an emphasis on procedures and mechanisms of implementation, it provides a multidimensional overview of human rights. Beginning with an analysis of the historical and conceptual foundations of human rights, the volume then focusses upon the different mechanisms which may be employed in translating human rights from a promise into a reality. Special emphasis is placed (...) upon the United Nations procedures available to achieve this end. (shrink)

Johann Friedrich Ludwig Schröder (1774-1845 ) was born in Germany but moved to Holland at the age of 13. After studying at Halle he joined the Kantian movement in Amsterdam as an active member, cooperating with Paulus van Hemert and contributing articles to his Kantian magazine. During his professional career as a marine instructor (1803-11 ), however, he became increasingly critical of Kantianism. As professor of mathematics, physics and philosophy at the University of Utrecht (1816-44) he traded in his former (...) Kantianism for a variant of the common sense philosophy then in favour in the Netherlands. He now regarded Kantianism as a form of scepticism. Accordingly, in his major work, the Contnbution to a Critique of the Truth of Human Knowledge, he propounds an anti-sceptical doctrine of such ‘basic truths’ as are founded on the immediate relevation of our consciousness. Schröder also attempts to reduce the Kantian doctrine of the noumenon to an inconsistent set of propositions, by showing them to be antinomies in the Kantian sense of the term, even using Kant's own dialectical method in proving their contradictoriness ; these contradictory propositions he calls the 'antinomies of the Kantian philosophy'. In a minor work, The Sign Relation as the Basis of Human Knowledge (translated freely), we find reminiscences of Thomas Reid's Inquiry into the Human Mind: of the doctrine of sensations suggesting our conceptions of things, of causes being the signs of their effects, of 'the natural language of mankind'. Schröder, in developing these ideas in his own way, presents the sign relation as being fundamental to the construction of our knowledge of both nature and the human soul. Only by taking one thing as the ‘sign’ (signal, symbol, symptom, index, expression, picture, representation etc.) of another can we attain a conception of the world as a coherent whole. Our perception of this relation is partly a matter of innate capacities, partly the result of acquired skill. (shrink)

This is my translation of Gadamer's 1990 lecture "The Diversity of Languages and Understanding of the World." "In his lecture, Gadamer presents his views of language and world in a distinctively hermeneutical key. For example, he emphasizes language as that which 'belongs to conversation.' That is, language as conversation helps to bring about understanding and involves the play of dialogical exchange. 'Language is not proposition and judgment; rather, it is what it is, only when it is question and answer.' Language (...) involves another; it is on-the-way [unterwegs] to another. In fact, when addressing his question—what does world mean—Gadamer clarifies that humans and world are intimately connected; the world is that in which we are 'in the midst' and 'understanding is understanding oneself in the world.' But we are also in-the-world with others, and understanding ourselves in the world, means to understand ourselves with others. Gadamer goes so far as to say that our self-understanding as achieved in relation to others, as well as our understanding of others, should be taken in a moral and political sense. That is, the other is not there as merely a means to our ends or to exploit. Rather, 'the other indicates a principal limit to our self-love and self-centeredness. This is a general moral problem. It is also a political problem.' He goes on to emphasize the difficult task of achieving genuine solidarity with those from different cultures. Such a task requires language as conversation, the back-and-forth of dialogical exchange in which we come to understand the other and the other comes to understand us. Again and again, Gadamer underscores the task that each of has in light of our pluralistic world “to learn to bridge and reconcile the distances and differences between us and that means that we respect, look after, care for the other, and give one other a new hearing.” In contrast with the story of the Tower of Babel in which the people sought a pseudo-unity or 'oneness' driven by a will to dominate, Gadamer embraces both cultural and linguistic diversity and warns against reducing these multiple horizons 'by any special contrivance of unity [Einheitsmechanik].' He encourages us to seek out the open spaces that arise in our interactions with one another, to resist the levelling of language that information technology tends toward, and to 'cultivate language in its most distinctive possibilities.' In our present age of disinformation warfare, which threatens democracies worldwide and is a direct challenge to truth and the possibility of a meaningful dialogue with others, we would do well to linger with Gadamer’s hermeneutical and ethical insights and contemplate how we might bring these insights to bear on the global and political crises that we face today—Russia’s war of aggression against Ukraine, our climate catastrophe, and ever new forms of technical sophistry and disinformation that seek to erode our trust in truth, reality, and language itself.".

By questioning the validity of some of our basic concepts, such as space, object, and causality, quantum physics contributes quite decisively to the dramatic changes now taking place in our world picture. Veiled Reality provides a detailed view of the reasons why such a questioning arises, a survey of the corresponding conceptual and theoretical problems, and a comprehensive, up-to-date account, useful to scientists and epistemologists alike, of the various ways present-day physicists tackle these problems.The book deals with the (...) E.P.R. reality criterion, local causality, and quantum measurement including relativistic quantum collapse, decoherence theories, consistent histories approaches, and ontologically interpretable theories. Questions bearing on the connection between counterfactuality and realism, intersubjective agreement, and limits of the bearing of the verbs “to have” and “to be,” follow naturally from the analysis and are thoroughly examined. Finally, distinguishing between empirical reality and a veiled independent reality whose only knowable features are structural yields a clue to a plausible interpretation of current physics.Accessible to readers with only very elementary background in modern physics, Veiled Reality offers nonspecialists, including students in physics and philosophy, easy access to basic problems in the foundation of physics.

The present work is motivated by recent experiments aimed to measure the propagation velocity of bound electromagnetic field that reveal no retardation in the absence of EM radiation. We show how these findings can be incorporated into the mathematical structure of special relativity theory that allows us to reconsider some selected problems of classical and quantum electrodynamics. In particular, we come to the conclusion that the total four-momentum for a classical system “particles plus fields” ought to be a present (...) state function of moving charges if EM radiation is negligible. In quantum domain, we analyze novel definition of the momentum operator recently suggested in the study of quantum phase effects. It implies that bound EM field energy and momentum are to be present state functions, too. Being in agreement with reported experiments, these conclusions suggest the necessity to carry out more precise experimental verifications for additional and independent determination of propagation properties of bound EM fields. A scheme of a possible experiment on this subject is also proposed. (shrink)

Beyond being the first substantial publication on Fourier, this work contains the text of Fourier's seminal paper of 1807 on the propagation of heat, marking the first time it has ever appeared in print. This paper incorporates many of the mathematical creations on which Fourier's fame rests, including derivation of the diffusion equation, the separation of the treatment of surface phenomena from internal phenomena, the use of boundary values and initial conditions, and the development of "Fourier series" and the so-called (...) "Bessel functions."When submitted to the examiners of the Institut de France, the originality of the paper and the surprising nature of some of its mathematical revelations caused great controversy, and it was denied publication both in 1807 and in later years. Fourier had the support, among the examiners, of Laplace and Monge, but Lagrange was adamantly in opposition, so that Fourier's work did not appear in print until 1822, reworked into book form.Fourier's mathematical discoveries are intimately related to his interest in the solution of physical problems and their experimental verification. The mathematical methods he developed in connection with heat diffusion apply to physical situations far beyond the boundaries of this area. Generally, Fourier may be credited with one of the first major extensions of mathematical physics beyond the applications of Newton's laws of motion and universal gravitation.The opening biographical chapter of this book follows Fourier's career up to the submission of the 1807 paper, and the two closing chapters take up his life and work from that point on. Fourier had strong political motivations and spent much of his life in the public service. These chapters trace his political difficulties, both before and after 1807, when he was the prefect of a department of France and was subjected to the dislocations of Napoleon's ups and downs. These chapters also describe aspects of the turbulent but productive development of French science from the Revolution to 1830.The core of the book presents the paper of 1807 in its original French and with the original notation. Grattan-Guinness has divided the paper into sections by the sequence of the problems taken up, and he introduces and, where necessary, closes each section with commentary relevant to Fourier's later work in these areas. The paper itself (cllows the chronology of Fourier's discoveries, and among the topics treated are, in this order: heat diffusion between disjoint bodies and in continuous bodies; the appearance of partial differential equations; the special solution for the lamina; sine and cosine series for an arbitrary function; reflections on the vibrating string problem; solution for the annulus; the full Fourier series for an arbitrary function; reflections on n-body analysis; solution for the sphere; solution for the cylinder; steady-state diffusion in the rectangular prism; time-dependent diffusion in the cube; and Fourier's experimental work.

Gottfried Wilhelm von Leibniz (1646-1716) has a prominent worldwide place in the history of scientific thought, from mathematics, logic, and physics to astronomy and engineering. In 2016, both his birth and death have been commemorated. Given the influence by Leibniz on Western sciences and philosophies and his polyhedric scientific activities, this special book chooses to focus on Leibniz's scientific works. In particular, we explore Leibniz's intellectual matrix and heritage within interdisciplinary fields, and present contributions from leading experts on the (...) subject. The book offers much-needed insights into the subject from scientific, historical, philosophical and nature of science perspectives. It also provides authoritative introductions to scholarly contributions, which are often dispersed in journals and books not easily accessible to every reader. Therefore, this volume also contains excellent chapters on topics which, generally speaking, have their place in any rounded science, history or philosophy topic. It provides an absorbing and significant read for historians, philosophers and scientists alike. Editors Raffaele Pisano is full professor at the Lille University, France.

Proximity and interpersonal contact are prominent components of social connection. Giving affective touch to others is fundamental for human bonding. This brief report presents preliminary results from a pilot study. It explores if exposure to bonding scenes impacts the activity of specific muscles related to physical interaction. Fingers flexion is a very important component when performing most actions of affectionate contact. We explored the visuo-motor affective interplay by priming participants with bonding scenes and assessing the electromyographic activity of the (...) fingers flexor muscle, in the absence of any overt movements. Photographs of dyads in social interaction and of the same dyads not interacting were employed. We examined the effects upon the electromyographical activity: during the passive exposure to pictures, and during picture offset and when expecting the signal to perform a fingers flexion task. Interacting dyads compared to matched non-interacting dyads increased electromyographic activity of the fingers flexor muscle in both contexts. Specific capture of visual bonding cues at the level of visual cortex had been described in the literature. Here we showed that the neural processing of visual bonding cues reaches the fingers flexor muscle. Besides, previous visualization of bonding cues enhanced background electromyographic activity during motor preparation to perform the fingers flexion task, which might reflect a sustained leakage of central motor activity downstream leading to increase in firing of the respective motor neurons. These data suggest, at the effector level, an implicit visuo-motor connection in which social interaction cues evoke intrinsic dispositions toward affectionate social behavior. (shrink)

What we perceive is the product of an intrinsic process and not part of external physical reality. This notion is consistent with the philosophical position of transcendental idealism but also agrees with physiological findings on the thalamocortical system. -Frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in thalamocortical networks, thereby transiently forming assemblies of coherent oscillations under constraints of sensory input and prefrontal attentional mechanisms. Perception and conscious experience may (...) be based on such assemblies and sensory input to thalamic nuclei plays merely a constraining role in their formation. In schizophrenia, the ability of sensory input to modulate self-organisation of thalamocortical activity may be generally reduced. If during arousal thalamocortical self-organisation is underconstrained by sensory input, then attentional mechanisms alone may determine the content of perception and hallucinations may arise.

For quite some time now philosophers have stressed the need to distinguish between explanatory (motivating) reasons and justifying (good) reasons. The distinction is often illustrated with an example of someone doing something that is intended to strike the reader or listener, at least at the outset, as incomprehensible. The story of Abraham on Mount Moriah, who decided to sacrifice his son, Isaac, illustrates this pattern. Killing one’s own child is a horrific thing to do, and it is hard to understand (...) what would drive a parent to do such a thing. But once we are informed that Abraham actually believed God had told him to do so, we can see (allegedly) that there is at least an explanation of why he decided to kill his son. In the eyes of most people the planned act remains awful. But once we assume that Abraham was mistaken (say, because the best explanation in this case need not postulate the existence of God), we can see that his decision to kill his son is not a response to a normative good reason.1 So in a few lines we have outlined two reason notions: explanatory and normative (good) reasons. Cases like this afford an intuitive grasp of the distinction between explanatory and normative reasons — the difference between what explains Abraham’s motivation and behaviour and the good or bad reasons that apply to him. However, more recently (see e.g. Dancy 2000) the picture such cases present has been supplemented, or perhaps even corrected. There is a further feature of the Abrahamic story that needs to be teased out — one that gives a finer-grained understanding of what is going on than that provided by talk of the agent’s explanatory reasons. I share this view, and so what I will be doing in this paper is mainly to underline the need to dig a bit deeper. Motivation, as I shall argue, comes in different forms . (shrink)

When viewed the history of Islamic thought, it is seen that the scholars have made an effort to understand the nature of the speech of God and make sense of it. Essentially, understanding and grasping of the words of God are an effort to look from the physical realm to the metaphysical one. In spite of this fact, the scholars as the indomitable seekers of truth are in search of finding some clues to say about it. While some of (...) them consider the “divine speech” as an attribute of God, many others view it as a divine act. It is also admitted by all of them that whether being attributive or act of God, the reflection of the divine speech is the Qur’ân. In this sense, three views have been put forward on the question of the belonging of the Qur’ânic words. According to the dominant and preferred point of view among these views, Qur’ân belongs to God in terms of wording and meaning. Accordingly, the revelation of the Qur’ân, which was revealed to the Prophet Mohammed consists of both wording and meaning. Therefore, there is no intervention or contribution of Gabriel or Muhammad in constituting of Qur’ân. According to the second approach, the meaning of Qur’ânic text belongs to God, however, its words pertain to Mohammed. This view signals that Gabriel revealed nothing more than the meanings of Qur’ân. Mohammed understands the meanings conveyed to him and then said them in Arabic expression patterns and phrases. According to the third approach, the meanings of Qur’ânic text belongs to God, however, its words pertain to Gabriel. In other words, only meanings of text were given to Gabriel, and its words are formed by him. In the present study, the mentioned approaches which are put forward by scholars about the belonging of Qur’ânic words will be examined in terms of the integrity of the Qur’ân and Tafsir rumors (riwâyât) of the classical period. In a nutshell, it can be said that there is no disagreement among scholars in the field of the belonging of the meanings of Qur’ânic text to God. The main disagreement is whether the Qur’ânic words belong to God, Gabriel or Muhammad. Considering the integrity of Qur’ân and Tafsir rumors regarding to the circumstances of sending down of the Qur’ânic revelation, it has been determined that the prevailing view is more consistent than the other two views.

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in (...) motion in the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments, after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics. (shrink)

Niels Bohr was born on October 7, 1885. He was one of the great innovators in physical science in the twentieth century. It so happens that 1985 also marks fifty years since the long discussions, which had begun in the 1920s between Albert Einstein and Bohr on the philosophical problems of quantum physics, attained their apogee. An article co-authored by Einstein, B. Podolsky, and N. Rosen, "Can Quantum Mechanics Be Considered a Complete Description of Physical Reality?," was (...) published in 1935 in the journal Physical Review. According to Bohr, "by virtue of its clarity and, it would seem, flawless argumentation, the work of Einstein, Podolsky, and Rosen has created excitement among physicists and played a great role in the discussion of general philosophical questions of physics." Precisely as a result of the publication of this article, the critical position of Einstein concerning quantum mechanics became known to a broader circle of physicists. In the same year, Bohr responded to Einstein and his co-authors with an article under the same title. (shrink)

This book provides a formal ontology of senses and the belief-relation that grounds the distinction between de dicto, de re, and de se beliefs as well as the opacity of belief reports. According to this ontology, the relata of the belief-relation are an agent and a special sort of object-dependent sense (a "thought-content"), the latter being an "abstract" property encoding various syntactic and semantic constraints on sentences of a language of thought. One bears the belief-relation to a thought-content T (...) just in case one (is disposed as one who) inwardly affirms a certain sentence S of one’s language of thought that satisfies what T encodes, which in turn requires that S’s non-logical parts stand in appropriate semantical relations to items specified by T. Since these items may include other senses as well as ordinary objects, beliefs of arbitrary complexity are automatically accommodated. Within the framework of the formal ontology, a context-dependent compositional semantics is then provided for a fragment of regimented English capable of formulating ascriptions of belief—a semantics that treats substitutional opacity as a genuine semantic datum. Finally, the resulting picture of belief and its attribution is defended by showing how it solves standard puzzles, avoids objections to rival accounts, and satisfies certain adequacy conditions not fulfilled by traditional theories. Along the way, clarification and defense is offered for the ingredient conception of object-dependent senses, and it is shown how adoption of the language of thought hypothesis permits Bertrand Russell’s obscure doctrine of logical forms to be understood in a way that not only vindicates his Multiple Relation theory of de re belief but also reveals the connection between these logical forms and thought-contents.

The discovery of the microworld presented a serious trial for many systems of views held by mankind, including its logic. This world was found to lack the familiar solid bodies, the unchanging particles and interrelations between them, the reflection of which, in one way or another, is the logic of the macroscopic world. What elementary particle physics encountered in the microscopic world seemed illogical: the rest-mass of a particle equals zero; a part that is not smaller than the whole; (...) a particle that in diffraction experiments moved like a wave; and much else that was unusual and strange in the properties of elementary particles. One of these properties was actually so named by physicists — "strangeness.". (shrink)
