While defining martial arts is not prerequisite to philosophizing about them, such a definition is desirable, helping us resolve disputes about the status of hard cases. At one extreme, Martínková and Parry argue that martial arts are distinguished from both close combat (as unsystematic) and combat sports (as competitive), and from warrior arts (as lethal) and martial paths (as spiritual). At the other extreme, mixed martial arts pundits and Bruce Lee speak of combat sports generally as martial arts. I argue (...) that the fine-grained taxonomy proposed by Martínková and Parry can be usefully supplemented by a broader definition, specifically the following: martial arts are systematic fighting styles and practices as ways of embodying wisdom. A possible difficulty here is that such views face the charge of overemphasizing the “philosophical” aspect of martial arts. My definition can, however, avoid this apparent problem. If martial arts essentially aim to embody wisdom, this applies no less to the (strategic) practical wisdom of The Art of War than to the (ethical) practical wisdom of the Tao Te Ching. In an extended sense, then, any systematic fighting style, including combat sports, may count as a martial art insofar as it embodies wisdom by improving practical fighting skills. (shrink)

Nobel Laureate in physics Wolfgang Pauli studied philosophy and the history of ideas intensively, especially in his later years, to form an accurate ontology vis-à-vis quantum theory. Pauli's close contacts with the Swiss psychiatrist C.G. Jung gave him special qualifications for also understanding the basic problems of empirical knowledge. After Pauli's sudden death in 1958, this work was maintained mainly in his posthumously published correspondence, which so far extends only to 1939. Because Pauli's view differs essentially from the (...) direction physics research took after the deaths of the founding fathers of quantum theory, this article attempts to describe the main features in Pauli's revolutionary thought, which is based on nature's “epistemological lesson” as revealed by Pauli's atomic research. Pauli's conclusions have important implications for various issues in Western culture, not least with the limits of science and the relation of science to religion. (shrink)

Quantum theory and the classical theory of computation were perfected in the 1930s, and fifty years later they were unified to form the quantum theory of computation. Here I want to tell you about a speculation — I can’t call it more than a “speculation” even though I know it’s true — about the kind of theory that might, in another fifty years’ time, supersede or transcend the quantum theory of computation. There are branches of science — in fact most (...) of them are branches of physics — that we expect, by their nature, to have philosophical implications. An obvious example is cosmology. There are other sciences, such as, say, aerodynamics, in which, no matter how startling or important our discoveries may become, we do not expect fundamental philosophical implications. So, various sciences fall at different places on a scale (Fig. 1) ranging from the most fundamental on the left to the least fundamental, the most derivative, on the right. (shrink)

Quantum theory is one the most important and successful theories of modern physical science. It has been estimated that its principles form the basis for about 30 per cent of the world's manufacturing economy. This is all the more remarkable because quantum theory is a theory that nobody understands. The meaning of Quantum Theory introduces science students to the theory's fundamental conceptual and philosophical problems, and the basis of its non-understandability. It does this with the barest minimum of jargon and (...) very little mathematics in the main text. Readers wishing to delve more deeply into the theory's mathematical subtleties can do so in an extended series of appendices. The book brings the reader up to date with the results of new experimental tests of quantum weirdness and reviews the latest thinking on alternative interpretations, the frontiers of quantum cosmology, quantum gravity and potential application of this weirdness in computing, cryptography and teleportation.

Since the bulk of this book is devoted to paraphrasing Aristotle's physical views for modern ears, it would have been more correctly styled an exposition or synopsis. As such, the work is of some value and may prove particularly helpful as an introduction. Though many of his expository comments are quite sensitive, the author takes for granted an uncritical acceptance of nineteenth century mechanics in those passages which attempt critical assessment of peripatetic natural science.—R.

Professor Solmsen's interpretation is orthodox; his comprehensive account builds on recent more specialized studies, including his own, and those of Jaeger, Ross, and Cherniss. If in some ways the book contains no large surprises, it nevertheless makes a major contribution by its treatment of Plato. The author has skillfully disengaged Plato's observations about nature from the customary ethical, epistemic, or, as the case may be, metaphysical contexts. He demonstrates that Plato was toward the end of his career a more serious (...) investigator of physical phenomena than is commonly supposed. Moreover, at almost every turn he finds Platonic precedents for Aristotle's thinking in this field. He does not detract from Aristotle's originality, but illumines it, and Plato's as well. (shrink)

Philosophy of Physics: A Very Short Introduction explores the core topics of philosophy of physics through three key themes: the nature of space and time; the origin of irreversibility and probability in the physics of large systems; how we can make sense of quantum mechanics. Central issues discussed include: the scientific method as it applies in modern physics; the distinction between absolute and relative motion; the way that distinction changes between Newton's physics and (...) special relativity; what spacetime is and how it relates to the laws of physics; how fundamental physics can make no distinction between past and future and yet a clear distinction exists in the world we see around us; why it is so difficult to understand quantum mechanics, and why doing so might push us to change our fundamental physics, to rethink the nature of science, or even to accept the existence of parallel universes.

Vol. I, Psychology (with Ethics and Religion)James WilberdingRichard Sorabji. The Philosophy of the Commentators, 200–600 AD: A Sourcebook. Vol. I, Psychology (with Ethics and Religion).

Paper, $39.50, each volume.Interest (...) in the Greek commentators continues to grow, thanks in large part to Richard Sorabji, who has done more than anyone else to reestablish them as at once faithful and original philosophers who remain relevant even to modern students of philosophy. The Sourcebook makes the commentators still more accessible by providing an introductory tool for the systematic exploration of their thought.Each volume contains a 30-page introduction consisting of roughly six sections: an explanation of the aims of the Sourcebook (1–5), a brief introduction to the commentators (5–12), a survey of issues relating to Neoplatonism (12–14) and the compatibility of Platonic and Aristotelian philosophy (14–19), a section entitled "The commentators and Christianity" (19–25), which is largely devoted to offering renewed support for Sorabji's suggestion from Aristotle Transformed (Cornell 1990) regarding the content of Ammonius's concession to the Christian patriarch in the 490s, and, finally, a short, volume-specific section designed to survey some of the innovations and disagreements in the respective subjects (25–28/29/30). Each volume is divided into between 18 and 28 topics, which are subdivided into as many as 26 subtopics (on average 5–6), and these subtopics are often further divided into as many as 8 subsections (on average roughly 4 subsections for every 10 subtopics). Nearly all subtopics and subsections contain introductions (typically one or two paragraphs, occasionally longer) as well as some interspersed annotations that together serve two functions: they review some of the relevant background passages—mostly from Plato and Aristotle, but also from the Presocratic and Hellenistic schools—and they introduce and summarize the passages contained in the Sourcebook by surveying some of the issues raised by the passages that follow. Both the introductions and the annotations are kept brief, since Sorabji's aim is to explain the relevant concepts "only so far as necessary for a first understanding" (4). The passages themselves are mostly drawn from surviving Greek as well as Latin texts of the commentators—a group that features Plotinus, Porphyry, and Proclus (see 4)—but also includes a handful of passages preserved only in Hebrew and Arabic. For example, included in the subtopic devoted to the status of nature (Physics 1[b]) is an English translation of a passage from Themistius preserved only in Averroes' Metaphysics. Over one hundred scholars contributed translations, though Sorabji emphasizes that in the interests of greater harmony he reworked them so that "the final versions are rather based on the work of the translators" (xvii). Often, Sorabji also refers to additional passages containing like-minded or opposing views not included in the Sourcebook, as well as cross-references to other passages in the Sourcebook. In most cases he provides a helpful selection of secondary literature on the subject. [End Page 470]There are some striking differences between the Sourcebook and two comparable introductory collections, Long and Sedley (LS), and Kirk, Raven, and Schofield (KRS), which might offer the clearest picture of the nature and objectives of the Sourcebook. The foremost of these is the very task of introducing periods in which the amount of surviving material is so different. Whereas of Hellenistic and especially of Pre-Socratic philosophy we have in large part only fragments, of the commentators we possess thousands of pages of Greek text. This means that the Sourcebook is the result of a long process of selection and systematization that ultimately captures only a fraction of the available material. Far from being a shortcoming, this belongs to the very nature of framing an introduction to such an extensive body of literature and would become problematic only if Sorabji wished to establish a canon of the philosophically significant texts of the period. He explicitly rejects such an aim, however (5). The Sourcebook also... (shrink)

In the course of the history of science, some concepts have forged theoretical foundations, constituting paradigms that hold sway for substantial periods of time. Research on the history of explanations of the action of one body on another is a testament to the periodic revival of one theory in particular, namely, the theory of ether. Even after the foundation of modern Physics, the notion of ether has directly and indirectly withstood the test of time. Through a spontaneous physics (...) philosophical analysis, this article will explore how certain aspects of the concept of ether have appeared in different branches of the history of science.

The main claim of this talk is that mathematical physics and philosophy of physics are not different. This claim, so formulated, is obviously false because it is overstated; however, since no non-tautological statement is likely to be completely true, it is a meaningful question whether the overstated claim expresses some truth. I hope it does, or so I’ll argue. The argument consists of two parts: First I’ll recall some characteristic features of von Neumann’s work on mathematical foundations (...) of quantum mechanics and will claim that von Neumann’s motivation and results are essentially philosophical in their nature; hence, to the extent von Neumann’s work exemplifies what is considered to be mathematical physics, mathematical physics appears as formally explicit philosophy of physics. The second argument is based on a rather trivial interpretation of what mathematical physics is. That interpretation implies that mathematical physics shares some key characteristic features with philosophy of physics which make the two almost indistinguishable. (shrink)

The seminal work by one of the most important thinkers of the twentieth century, Physics and Philosophy is Werner Heisenberg's concise and accessible narrative of the revolution in modern physics, in which he played a towering role. The outgrowth of a celebrated lecture series, this book remains as relevant, provocative, and fascinating as when it was first published in 1958. A brilliant scientist whose ideas altered our perception of the universe, Heisenberg is considered the father of quantum (...) physics; he is most famous for the Uncertainty Principle, which states that quantum particles do not occupy a fixed, measurable position. His contributions remain a cornerstone of contemporary physics theory and application. Book jacket. (shrink)

In our daily lives we conceive of our surroundings as an objectively given reality. The world is perceived through our senses, and ~hese provide us, so we believe, with a faithful image of the world. But occ~ipnally we are forced to realize that our senses deceive us, e. g., by illusions. For a while it was believed that the sensation of color is directly r~lated to the frequency of light waves, until E. Land (the inventor of the polaroid camera) showed (...) in detailed experiments that our perception of, say, a colored spot depends on the colors of its surrounding. On the other hand, we may experience hallucinations or dreams as real. Quite evidently, the relationship between the "world" and our "brain" is intricate. Another strange problem is the way in which we perceive time or the "Now". Psychophysical experiments tell us that the psychological "Now" is an extended period of time in the sense of physics. The situation was made still more puzzling when, in the nineteen-twenties, Heisenberg and others realized that, by observing processes in the microscopic world of electrons and other elementary particles, we strongly interfere with that world. The outcome of experiments - at least in general - can only be predicted statistically. What is the nature ofthis strange relationship between "object" and "observer"? This is another crucial problem of the inside-outside or endo-exo dichotomy. (shrink)

The author focuses on the tension "realism - idealism" in the philosophy of mathematics, but he does that from the perspective of a theoretical physicist. It is not only that one's standpoint in the philosophy of mathematics determines our understanding of the effectiveness of mathematics in physics, but also the fact that mathematics is so effective in physical sciences tells us something about the nature of mathematics.

Through both an historical and philosophical analysis of the concept of possibility, we show how including both potentiality and actuality as part of the real is both compatible with experience and contributes to solving key problems of fundamental process and emergence. The book is organized into four main sections that incorporate our routes to potentiality: potentiality in modern science [history and philosophy; quantum physics and complexity]; Relational Realism [ontological interpretation of quantum physics; philosophy and logic]; Process (...) Physics [ontological interpretation of relativity theory; physics and philosophy]; on speculative philosophy and physics [limitations and approximations; process philosophy]. We conclude that certain fundamental problems in modern physics require complementary analyses of certain philosophical and metaphysical issues, and that such scholarship reveals intrinsic features and limits of determinism, potentiality and emergence that enable, among others, important progress on the quantum theory of measurement problem and new understandings of emergence.

A sophisticated and original introduction to the philosophy of quantum mechanics from one of the world’s leading philosophers of physics In this book, Tim Maudlin, one of the world’s leading philosophers of physics, offers a sophisticated, original introduction to the philosophy of quantum mechanics. The briefest, clearest, and most refined account of his influential approach to the subject, the book will be invaluable to all students of philosophy and physics. Quantum mechanics holds a unique (...) place in the history of physics. It has produced the most accurate predictions of any scientific theory, but, more astonishing, there has never been any agreement about what the theory implies about physical reality. Maudlin argues that the very term “quantum theory” is a misnomer. A proper physical theory should clearly describe what is there and what it does—yet standard textbooks present quantum mechanics as a predictive recipe in search of a physical theory. In contrast, Maudlin explores three proper theories that recover the quantum predictions: the indeterministic wavefunction collapse theory of Ghirardi, Rimini, and Weber; the deterministic particle theory of deBroglie and Bohm; and the conceptually challenging Many Worlds theory of Everett. Each offers a radically different proposal for the nature of physical reality, but Maudlin shows that none of them are what they are generally taken to be. (shrink)

In 1966 the Brazilian physicist Klaus Tausk (b. 1927) circulated a preprint from the International Centre for Theoretical Physics in Trieste, Italy, criticizing Adriana Daneri, Angelo Loinger, and Giovanni Maria Prosperi`s theory of 1962 on the measurement problem in quantum mechanics. A heated controversy ensued between two opposing camps within the orthodox interpretation of quantum theory, represented by Leon Rosenfeld and Eugene P. Wigner. The controversy went well beyond the strictly scientific issues, however, reflecting philosophical and political commitments within (...) the context of the Cold War, the relationship between science in developed and Third World countries, the importance of social skills, and personal idiosyncrasies.

The study of the physical world had its origins in philosophy, and, two-and-one-half millennia later, the scientific advances of the twentieth century are bringing the two fields closer together again. So argues Lawrence Sklar in this brilliant new text on the philosophy of physics.Aimed at students of both disciplines, Philosophy of Physics is a broad overview of the problems of contemporary philosophy of physics that readers of all levels of sophistication should find accessible (...) and engaging. Professor Sklar’s talent for clarity and accuracy is on display throughout as he guides students through the key problems: the nature of space and time, the problems of probability and irreversibility in statistical mechanics, and, of course, the many notorious problems raised by quantum mechanics.Integrated by the theme of the interconnectedness of philosophy and science, and linked by many references to the history of both disciplines, Philosophy of Physics is always clear, while remaining faithful to the complexity and integrity of the issues. It will take its place as a classic text in a field of fundamental intellectual importance. (shrink)

Among the great ironies of quantum mechanics is not only that its conceptual foundations seem strange even to the physicists who use it, but that philosophers have largely ignored it. Here, Bernard d'Espagnat argues that quantum physics--by casting doubts on once hallowed concepts such as space, material objects, and causality-demands serious reconsideration of most of traditional philosophy. On Physics and Philosophy is an accessible, mathematics-free reflection on the philosophical meaning of the quantum revolution, by one of (...) the world's leading authorities on the subject. D'Espagnat presents an objective account of the main guiding principles of contemporary physics-in particular, quantum mechanics-followed by a look at just what consequences these should imply for philosophical thinking. The author begins by describing recent discoveries in quantum physics such as nonseparability, and explicating the significance of contemporary developments such as decoherence. Then he proceeds to set various philosophical theories of knowledge--such as materialism, realism, Kantism, and neo-Kantism--against the conceptual problems quantum theory raises. His overall conclusion is that while the physical implications of quantum theory suggest that scientific knowledge will never truly describe mind-independent reality, the notion of such an ultimate reality--one we can never access directly or rationally and which he calls "veiled reality"--remains conceptually necessary nonetheless.

Visit the author's Web site at www.11PicsOfTime.com Time is a mystery that has perplexed humankind since time immemorial. Resolving this mystery is of significance not only to philosophers and physicists but is also a very practical concern. Our perception of time shapes our values and way of life; it also mediates the interaction between science and religion both of which rest fundamentally on assumptions about the nature of time. C K Raju begins with a critical exposition of various time-beliefs, ranging (...) from the earliest times through Augustine, Newton and Einstein to Stephen Hawking and current notions of chaos and time travel. He traces the role of organised religion in subverting time beliefs for its political ends. The book points out how this resulted in a facile dichotomy between 'linear' and 'cyclic' time, thereby inaugurating a confusion which, according to the author, has handicapped Western thought ever since, eventually influencing the content of science itself. Thus, this book daringly asserts that physical theory, traditionally regarded as amoral and objective, has depended on cultural beliefs about time. The author points out that time beliefs are again being manipulated today as the credibility of science is being exploited to promote a picture of time and, hence, a pattern of human behaviour which is convenient to the agenda of globalisation of culture. The linkages between modern theology and this 'brave new physics' are traced against the wider context of the so-called 'clash of civilisations', and the attempts to remake the world order. The conclusions point to the need to de-theologise time. The author challenges Einstein's understanding of relativity theory and suggests that a 'tilt in the arrow of time', or a small tendency towards cyclicity, will help repair the prevalent confusion about time. A 'tilt' also enables a physics that permits both memory and creativity, so that purpose and spontaneous growth of order are returned to human life. The book ends with a vision of Man as Creator, surprising God. Extensive research in physics, the history of science, comparative religions, and sociology lend weight to the important and challenging conclusions reached by the author. Written as a rejoinder to Stephen Hawking's A Brief History of Time, this book goes much further and, unlike any previous book, it gives a critical exposition of various world religions-Buddhism, Christianity, Hinduism, Islam, and Jainism-while exploring their intricate links, through time beliefs, to current physics on the one hand, and to global political and economic trends, on the other. This book will appeal to scholars and laypersons equally. It will fascinate anyone who reads it and will teach its readers to question the unquestionable. (shrink)

A magisterial study of the philosophy of physics that both introduces the subject to the non-specialist and contains many original and important contributions for professionals in the area. Modern physics was born as a part of philosophy and has retained to this day a properly philosophical concern for the clarity and coherence of ideas. Any introduction to the philosophy of physics must therefore focus on the conceptual development of physics itself. This book pursues (...) that development from Galileo and Newton through Maxwell and Boltzmann to Einstein and the founders of quantum mechanics. There is also discussion of important philosophers of physics in the eighteenth and nineteenth centuries and of twentieth-century debates. In the interest of appealing to the broadest possible readership the author avoids technicalities and explains both the physics and philosophical terms. (shrink)

During the sixteenth and early seventeenth centuries, physics was regularly taught as part of instruction in philosophy and the arts at Central European schools and universities. However, physics did not have a special or privileged status within that instruction. Three general indicators of this lack of special status are suggested in this article. First, teachers of physics usually were paid less than teachers of most other university-level subject-matters. Second, very few Central European academics during this period (...) appear to have made a career out of teaching physics. And third, Reformation Era schools and universities in Central Europe emphasized language instruction; such instruction not only was instrumental in promoting the confessional-i.e., Calvinist, Lutheran, and Roman Catholic-agendas of those same schools and universities, but also helped to prepare students for service in nascent but growing state governments.

Historians of science have long been intrigued by the impact of disparate cultural styles on the science of a given country and time period. Richard Olson’s book is a case study in the interaction between philosophy and science as well as an examination of a particular scientific movement. The author investigates the methodological arguments of the Common Sense philosophers Thomas Reid, Dugald Stewart, Thomas Brown, and William Hamilton and the possible transmission of their ideas to scientists from John Playfair (...) to James Clerk Maxwell. His findings point out the need for modifications to the Duhem-Poincaré interpretation of British scientific style and the reassessment of the extent of Kantian influence on British physics.
