In his monumental 1687 work, _Philosophiae Naturalis Principia Mathematica_, known familiarly as the _Principia_, Isaac Newton laid out in mathematical terms the principles of time, force, and motion that have guided the development of modern physical science. Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles. (...) This authoritative, modern translation by I. Bernard Cohen and Anne Whitman, the first in more than 285 years, is based on the 1726 edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the _Principia_ also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system. The translation-only edition of this preeminent work is truly accessible for today's scientists, scholars, and students. (shrink)

The author argues that Newton’s distinction between absolute and relative motion, i.e. the refusal to define motion in relation to sensible things, in “Scholium on time, space, place and motion” from _Mathematical Principles of Natural Philosophy_, stems in great part from his critical stance towards Descartes’s philosophy of nature. This is apparent from the comparison of “Scholium”, in which Descartes is not mentioned at all, with Newton’s criticism of him in his manuscript _De gravitatione_. The positive results of Newton’s encounter (...) with Descartes’s theory of motion is almost completely identical to those of the “Scholium”: the definition of motion must concern the whole body and not just its surface; instead of “mutual translation”, it must include the force that is the cause of the physical motion; the motion of the bodies is uniform and straightforward, which can only be achieved within absolute space. As far as the theory of motion is concerned, Newton’s philosophical challenge was always Descartes. (shrink)

Книгата проследява зараждането на един от най-важните и продължителни исторически конфликти във философията на природата: борбата между релативисти и абсолютисти по отношение на пространството, времето и движението. Катализатор на този конфликт е Рене Декарт - първият, опитващ се да създаде последователна релационистична система във физиката, която обаче започва да ерозира още с възраженията на Нютон. Изследването разкрива и разгръща фундаменталните светогледни позиции на двамата учени през персонална, понятийна и контекстуална рамка.

Three events, which happened all within the same week some ten years ago, set me on the track which the book describes. The first was a reading of Emile Meyerson works in the course of a prolonged research on Einstein's relativity theory, which sent me back to Meyerson's Ident ity and Reality, where I read and reread the striking chapter on "Ir rationality". In my earlier researches into the origins of French Conven tionalism I came to know similar views, (...) all apparently deriving from Emile Boutroux's doctoral thesis of 1874 De fa contingence des lois de la nature and his notes of the 1892-3 course he taught at the Sorbonne De ['idee de fa loi naturelle dans la science et la philosophie contempo raines. But never before was the full effect of the argument so suddenly clear as when I read Meyerson. On the same week I read, by sheer accident, Ernest Moody's two parts paper in the JHIof 1951, "Galileo and Avempace". Put near Meyerson's thesis, what Moody argued was a striking confirmation: it was the sheer irrationality of the Platonic tradition, leading from A vem pace to Galileo, which was the working conceptual force behind the notion of a non-appearing nature, active all the time but always sub merged, as it is embodied in the concept of void and motion in it.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Philosophy of PhysicsMartin CurdRoberto Torretti. The Philosophy of Physics. Cambridge: Cambridge University Press, 1999. Pp. xvi + 512. Cloth, $64.95. Paper, $23.95.This is the first volume in a new Cambridge series, "The Evolution of Modern Philosophy." It is a historical work, tracing the interaction between physics and philosophy from the scientific revolution of the seventeenth century through general relativity and quantum mechanics in the twentieth century. (...) The emphasis is on the philosophy in physics (rather than philosophizing about physics) and, with the exceptions noted below, the focus is on scientists (scientist-philosophers in many cases) rather than philosophers outside of science. Most of the book is about the conceptual and mathematical development of the core branches of physics (mainly mechanics, but also geometry, thermodynamics, and field theory). There are seven chapters plus three supplements giving the mathematical essentials of vector analysis, lattice theory, and topology.The hero of chapter one is Galileo who, more than anyone else prior to Newton, set physics on its modern path towards mathematization and away from Aristotle. Also discussed in chapter one are Descartes, Huyghens, and Leibniz. Chapter two is devoted to Newton (both the foundations of Newtonian mechanics and the derivation of the law of universal gravitation) and follows the development of analytical mechanics up to Lagrange and Hamilton. Chapter three, appropriately entitled "Kant," is the only chapter devoted to a philosopher. After a brief discussion of Leibniz, Berkeley, and Kant's pre-critical writings, it covers the important scientific topics in the Critique of Pure Reason (space, time, the three Analogies) but avoids the Metaphysical Foundations of Natural Science (referring the reader to Michael Friedman's Kant and the Exact Sciences). Chapter four looks at scientific developments in three areas that proved to be important for twentieth-century physics: non-Euclidean geometry from Lobachevsky to Riemann, electromagnetic field theory (Maxwell), and thermal physics (classical thermodynamics, the kinetic theory, and statistical mechanics) from Carnot to Boltzmann. The chapter concludes, somewhat untidily, with a section on four philosophers of science (Whewell, Peirce, Mach, and Duhem), selected, we are told, because of their influence on philosophy of science in the second half of the twentieth century. (For the "two great philosopher-scientists" Helmholtz and Poincaré, the reader is referred to Torretti's earlier books, Philosophy of Geometry from Riemann to Poincaré, and Relativity and Geometry.) Chapter five covers both the special and general theory of relativity. After a masterful exposition of the special theory and its Minkowski spacetime representation, the usual topics of philosophical interest are discussed; these include the conventionality of simultaneity thesis, the twin paradox, the relativistic concept of mass, and determinism. The rather brief treatment of the general theory is, unavoidably, mathematically demanding and carries the subject through to recent inflationary cosmological models. Chapter six (also mathematically demanding at times) examines the development and structure of quantum mechanics, aptly praised as "one of the most elegant creations of the human spirit" (340). Torretti wisely ignores the complexities of quantum field theory since the philosophical problems discussed—measurement, the EPR paradox, the interpretation of the y-function—remain when quantum mechanics is made Lorentz invariant; but he urges philosophers of science to follow the lead of Michael Redhead and [End Page 602] Paul Teller in exploring its metaphysical ramifications. Of special note are the author's trenchant criticisms of attempts to solve the quantum mysteries by Bohr (complementarity), Bohm (hidden variables), Putnam (quantum logic), and Everett (the many worlds interpretation). The book concludes with the author's reflections on issues in the philosophy of science. Torretti defends the structuralist explication of physical theories (more familiarly known as the semantic conception or the model-theoretic view) that informs much of his book, arguing that it succeeds where the "received view" of logical empiricism failed while avoiding Kuhnian incommensurability—"a pseudoproblem that made philosophy of science the laughing stock of practicing physicists" (404). The chapter ends with an attack on inductive logic: "one of the blindest alleys in twentieth-century philosophy" (437).The writing is admirably clear and the author has done a commendable job of explaining the arguments of historical scientists while presenting their theories in a clear...

Although Descartes’ natural philosophy marked an important advance in the development of modern science, many of his specific concepts of science have been largely discarded, and consequently neglected, since their introduction in the seventeenth century. Many critics over the years, such as Newton (in his early paper De gravitatione), have presented a series of apparently devastating arguments against Descartes' theory of space and motion; a generally negative historical verdict which, moreover, most contemporary scholars accept. Nevertheless, it is also true that (...) most historians and philosophers of science have not sufficiently investigated the viability and effectiveness of the case against Cartesian space and motion. This book explores the success of the arguments against Descartes’ theory of space and motion by determining if it is possible to formulate a Cartesian theory of science that can avoid the problems raised by Newton, as well as by a host of other past and contemporary philosophers either sympathetic or hostile to the overall design of Cartesian science. In particular, if Descartes' theory of motion can be reconciled with his hypotheses on dynamics, then a Cartesian can successfully resolve the difficulties imposed by his critics. This book comprises, therefore, a sustained attempt to construct a consistent “Cartesian” spacetime theory: i.e., a theory of space and time that incorporates Descartes’ various theories of physics and nature without falling into the kinds of problems and contradictions as charged by, for example, Newton.

Presents Newton's unifying idea of gravitation and explains how he converted physics from a science of explanation into a general mathematical system.

Descartes' Discourse marks a watershed in European thought; in it, the author sets out in brief his radical new philosophy, which begins with a proof of the existence of the self (the famous "cogito ergo sum"). Next he deduces from it the existence and nature of God, and ends by offering a radical new account of the physical world and of human and animal nature. Written in everyday language and meant to be read by common people of the day, it (...) swept away all previous philosophical traditions. This new translation is an ideal introduction to Descartes for the general reader. It is accompanied by a substantial introductory essay from Renaissance scholar Ian Maclean that is designed to provide in-depth historical and philosophical context. The essay draws on Descartes' correspondence to examine what brought him to write his great work, and the impact it had on his contemporaries. A detailed section of notes explain Descartes' philosophical terminology and ideas, as well as historical references and allusions. Any reader can feel comfortable diving in to this classic work of Renaissance philosophical thought. (shrink)

Sir Isaac Newton (1642-1727) left a voluminous legacy of writings. Despite his influence on the early modern period, his correspondence, manuscripts, and publications in natural philosophy remain scattered throughout many disparate editions. In this volume, Newton's principal philosophical writings are for the first time collected in a single place. They include excerpts from the Principia and the Opticks, his famous correspondence with Boyle and with Bentley, and his equally significant correspondence with Leibniz, which is often ignored in favor of Leibniz's (...) later debate with Samuel Clarke. Newton's exchanges with Leibniz place their different understandings of natural philosophy in sharp relief. The volume also includes 'De Gravitatione', offered here in a corrected translation, which is crucial for understanding Newton's relation to his great predecessor Descartes. In a historical and philosophical introduction, Andrew Janiak examines Newton's philosophical positions and his relations to canonical figures in early modern philosophy. (shrink)

Concentrating mainly on the process philosophy developed by Alfred North Whitehead, this series of essays brings together some of the newest developments in the application of process thinking to the physical and social sciences.

Now, it seems to me that there is much philosophy written today that does not justify our recognizing such relativism as characteristic of recent thought. In fact, however dominant this way of thinking may appear in other fields, a freshly oriented concern for an absolute may be detected in twentieth-century philosophy. Such concern is for an absolute within rather than behind or above our experience--if you will, for a finite absolute. For such a philosophy, the absolute has not so much (...) "fallen" as settled down, "down to earth" so to speak, where it enters our daily experience. Thus the one of Parmenides whose presence pulverized our common sense is no longer with us, nor are we likely to revive it, but we do hear of an absolute reality present in our conscious lives. Witness Sartre's insistence upon the "absolute character of free involvement" or choice, in contrast with his dismissal of the l'être en soi et pour soi as an impossible ideal. The cogito of Descartes, rather than his perfect being, appears as the historical archetype of our absolute. Thus today the metaphysician is often more concerned with what we way call the quality of man than with the more traditional efforts to discuss cosmic horizons, even though a traditional concern for an authentic reality continues to inspire his work.

In this work, the first of a series, we study the nature of informal inconsistency in physics, focusing mainly on the foundations of quantum theory, and appealing to the concept of quasi-truth. We defend a pluralistic view of the philosophy of science, grounded on the existence of inconsistencies and on quasi-truth. Here, we treat only the ‘classical aspects’ of the subject, leaving for a forthcoming paper the ‘non-classical’ part.

A series of lectures organized in part by the Society for Applied Philosophy and entitled ‘Philosophy and Practice’ is presumably aimed at displaying the practical implications of philosophical doctrines and/or applying philosophical skills to practical questions.

For as will be argued there are a number of theses concerning the role of interests in science which have considerable implications for how one should see the scientific (...) enterprise in general and in particular for how one assesses the claim that science ought to be accorded its priviliged position in virtue of its results and/or methods And in view of the respect and resources accorded to science what could be of greater practical interest? It remains the case, however, that my interest may seem the inverse of that of the organizers of this series. For in looking at the role of interest in science, one is examining, so to speak, the extent to which the sphere of the practical determines what goes on in science. One is exploring ways in which the non-scientific impinges on the scientific. While my primary focus will be on the physical sciences, it will be argued that there is a significant difference between them and the social sciences; a difference which renders the social sciences intrinsically liable to penetration from outside. As will be seen, some of the particular arguments for this conclusion make pressing the question: what about philosophy? The answer, it will be concluded, is that philosophy is insulated from external influences to a considerable extent. In that lies both its importance and an explanation as to why much of it has little practical application. (shrink)

In this chapter, the author presents some Cartesian thought experiments by reproducing an excerpt from The Meditations on First Philosophy. The author asks us to imagine that the physical world around us is an elaborate illusion. He imagines that the world was merely a dream or, worse yet, a hoax orchestrated by an evil demon bent on deceiving us. The author asks us to suppose that we are dreaming, and that some particulars ‐ namely, the opening of the eyes, the (...) motion of the head, the forth‐putting of the hands ‐ are merely illusions; and even that we really possess neither an entire body nor hands such as we see. Nevertheless, he says that, it must be admitted at least that the objects which appear to us in sleep are, as it were, painted representations which could not have been formed unless in the likeness of realities.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Wittgenstein in Cambridge: Letters and Documents, 1911–1951Newton GarverBrian McGuinness, editor. Wittgenstein in Cambridge: Letters and Documents, 1911–1951. Malden, MA-Oxford: Blackwell Publishing. Pp. vii + 498. Cloth, $134.95.This volume includes nearly everything contained in Cambridge Letters (Blackwell, 1995), supplemented by Wittgenstein’s exchanges with Sraffa (not available in 1995), by correspondence with many of his students, and by various documents pertaining to his status in the University and to the (...) Moral Sciences meetings. Throughout, there are notes by McGuinness that provide details about persons, places, and events mentioned in the texts. Altogether, the volume offers rich rewards for both students of Wittgenstein and those interested in the interplay of the times.Wittgenstein was Austrian to the core, as is evident in his admiration for such distinctly Viennese cultural icons as Nestroy, Grillparzer, Labor, Weininger, and Kraus—none of whom was familiar in the circles within which he moved in Cambridge. In his introduction, however, McGuinness makes clear that Cambridge, not Vienna, was the place where Wittgenstein could work. There were no roots in Cambridge, compared to those in Vienna, but growth, it seems, had to take place away from the roots. During his first stay in Cambridge (1912–14) Wittgenstein established connections with the giants of the time: Russell, Moore, and Keynes, all of whom had been active members of the Apostles, and who therefore put him in touch with the Bloomsbury-flavored younger elite of the University. Although none of these relationships was smooth, they all served in 1929 to ease Wittgenstein’s re-entry into Cambridge.Once back at Cambridge, and back at work in philosophy, Wittgenstein established his own circle, composed of younger scholars who attended his lectures. The only contact from the early period with whom he remained close through the 1930s and ’40s was Moore, although neither Russell nor Keynes disappeared entirely. Moore attended Wittgenstein’s lectures in 1930–33, and the two met regularly whenever Wittgenstein was in Cambridge. Among his peers, the big addition was Piero Sraffa, the Italian economist who was, as McGuinness puts it, first a protegé and then a successor of Keynes. It is difficult to reconstruct the content of the conversations between these two powerful intellects, but the letters and notes included here make it plain that the conversations were intense and had continuing themes. The Sraffa documents have been available elsewhere, but the chronological order of the documents in this volume means that we can now see them in the wider context of Wittgenstein’s ongoing activity.Wittgenstein and Sraffa were both equals and opposites—equal in genius, in honesty, in forthrightness, in stubbornness, and in commitment to dialogue, but opposite in opinions and convictions. Time and again, the letters and notes show evidence of tough, wrenching discussions, at times suspended because of exhaustion and weariness. Wittgenstein lists Sraffa last (chronologically, we presume) of ten people who influenced his thought. The letters and notes in this volume confirm a powerful influence, but offer scant clues as to the direction of the influence in Wittgenstein’s later thought.One of the younger scholars was the physicist W. H. Watson, who became Distinguished Professor at Queen’s University in Kingston, Ontario. His On Understanding Physics is, [End Page 115] McGuinness reports, a reliable guide of Wittgenstein’s thinking on these matters. In their correspondence we find many instances of what they both regarded as nonsense penned by the great scientists of the day (Jeans, Eddington, and Einstein). The nonsense appears to have presented grand pronouncements in everyday language, concerning mundane rather than distinctively philosophical matters. By providing new insight into how Wittgenstein relished nonsensical items, the correspondence with Watson helps us appreciate Wittgenstein’s nose for nonsense as part of his philosophical genius.For Wittgenstein, happiness depended on work. This is evident in his Notebooks 1914–1916 and again in these documents. For example, on June 17, 1941, he writes to Moore, “About six weeks ago I suddenly... began to be able to write again. Quite possibly this will last only for a very short time; but it feels good while it lasts and has made a great deal of difference to me... (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.

Jāmī's Lawā'iḥ from the Persian by William C. Chittick. By Sachiko Murata, with a foreword by Tu Weiming. Albany: State University of New York Press, 2000. Pp. xiv + 264.Contacts between China and the Near East are at least as old as civilization but have been relatively little studied. This has led to a lack of attention to Chinese Islam. Yet, Islam has been a profoundly influential force in China for centuries. In Chinese Gleams of Sufī Light, Sachiko Murata has stepped forward to bring a wider awareness to the interactions between Chinese Islam and native Chinese philosophic traditions. (Murata is also the author of The Tao of Islam [1992] and, with Islamicist William Chittick, The Vision of Islam [1994]). [End Page 257]The present book adds greatly to our understanding. It includes a translation of The Great Learning of the Pure and Real, by Wang Tai-yü (ca. 1590-ca. 1658) and facing-page versions of William Chittick's English translation of the fifteenth-century Gleams (Lawā'iḥ) by 'Abd al-Rahman Jāmī and Murata's English translation of Liu Chih's (ca. 1662-ca. 1730) Chinese version of the same work. (Here, incidentally, I follow the book in using the Wade-Giles system.) One can see, comparing the translations, howLiu recast Jāmī's work in Chinese philosophic language, paraphrased some difficult passages, summarized others, and added his own commentaries.Interestingly, Liu eliminated Jāmī's Persian poetry. Murata thinks this is because Liu wanted to focus on the hard ideas; I suspect that it was because Liu realized that Persian prosody and imagery were too far from Chinese poetry to please his audience.Both Wang and Liu belonged to what must have been a rather loose but some-how connected circle of Chinese Islamic scholars. Both, also, almost necessarily used language fairly widespread in Chinese philosophy. Terms such as "emptiness" and "transformation" had many Chinese resonances, some most un-Islamic (Neo Confucian and Buddhist, for instance).Neither Chittick nor Murata give any glosses for key philosophical terms in either source language. Their philosophical and religious provenance, Chinese or Muslim, is correspondingly unclear.What is clear is that Neo-Confucianism had a strong influence on these scholars. Haqiqa "reality" is often translated as li "principle." Pen-jan "root nature" is used for the Arabic compound "essence and attributes." These examples are discussed in the introduction (p. 19). "Annihilation" becomes "conquering" (pp. 148-149). This is strange, because "Annihilation" (fana') is a technical term in Sufism for the disappearance of the self in God; it is an Arabic term, and literally means something like. "passing away." It signifies the forgetting or loss of self, such that only contemplation of the Divine remains. It is as close to the Divine as humans can get since, in Islam, humans cannot be absorbed into Allah (as, in Buddhism, they can be absorbed into Nirvāṇa or the Buddha-nature). "Conquering" seems a rather strange way to express this in Chinese. Perhaps Chinese Muslim readers of the time had developed this specialized sense for it.There are, of course, debatable translations here to contend with (both from Persian and Arabic to Chinese and from Persian and Chinese into English), but it appears that real incommensurability is involved. It was very difficult to use the language of Chinese philosophy in the seventeenth century, influenced as it was by centuries of Neo-Confucian thought, to talk about a radically different religion characterized by an infinitely powerful and wise God, aware of all futures, close to the believer and yet cut off.The inevitable result is to wedge the Arabic and Persian philosophy, so heavily informed by Neoplatonic essentialism and other...

This paper compares Newton’s and Descartes’s conceptions of the complex relationship between physics and metaphysics.

In this essay I reassess Willem Jacob ‘s Gravesande's Newtonianism. I draw attention to ‘s Gravesande's a-causal rendering of physics which went against Newton's causal understanding of natural philosophy and to his attempt to establish a solid foundation for the certainty of Newton's natural philosophy, which he considered as a powerful antidote against the theological aberrations of Descartes and especially Spinoza. I argue that, although ‘s Gravesande clearly took inspiration from Newton's natural philosophy, he was running his own scientific and (...) intellectual agenda and that he was combining Newtonian and non-Newtonian elements.

The Reeh-Schlieder theorem asserts the vacuum and certain other states to be spacelike superentangled relative to local quantum fields. This motivates an inquiry into the physical status of various concepts of localization. It is argued that a covariant generalization of Newton-Wigner localization is a physically illuminating concept. When analyzed in terms of nonlocally covariant quantum fields, creating and annihilating quanta in Newton-Wigner localized states, the vacuum is seen to not possess the spacelike superentanglement that the Reeh-Schlieder theorem displays relative to (...) local fields, and to be locally empty as well as globally empty. Newton-Wigner localization is then shown to be physically interpretable in terms of a covariant generalization of the center of energy, the two localizations being identical if the system has no internal angular momentum. Finally, some of the counterintuitive features of Newton-Wigner localization are shown to have close analogues in classical special relativity. (shrink)

The issue of what consequences to draw from the existence of non-classical logical systems has been the subject of an interesting debate across a diversity of fields. In this paper the matter of alternative logics is considered with reference to a specific belief system and its propositions :the Azande are said to maintain beliefs about witchcraft which, when expressed propositionally, appear to be inconsistent. When the Azande have been presented with such inconsistencies, they either fail to see them as such (...) or else accept them as non-problematical. Is our knowledge of logical truths a relative and culturally determined phenomenon, or is there some (transcendent) criterion that allows us to adjudicate between alternative logical systems? The authors propose an approach for resolving disputes about the status of Azande reasoning which assumes a paraconsistent framework, thus providing a new perspective on this debate. (shrink)

The two books discussed here make important contributions to our understanding of the role of spacetime concepts in physical theories and how that understanding has changed during the evolution of physics. Both emphasize what can be called a ‘dynamical’ account, according to which geometric structures should be understood in terms of their roles in the laws governing matter and force. I explore how the books contribute to such a project; while generally sympathetic, I offer criticisms of some historical claims concerning (...) Newton, and argue that the dynamical account does not undercut ontological issues as the books claim. *Received January 2009; revised March 2009. †To contact the author, please write to: Department of Philosophy, 1423 University Hall MC 267, University of Illinois at Chicago, 601 S.

The concept of force can seem comparatively unproblematic—forces are responsible for making things move. However, the history of both physics and metaphysics reveals considerable controversy concerning both the nature of forces, and their very existence. My survey takes in the Greek atomists, Aristotelian physics, the “mechanical” philosophy of the scientific revolution, the innovations of Descartes and Newton, Hume-inspired skepticism, the dynamism of Leibniz, Kant and Boscovich, the field theories of Faraday and Maxwell, and the impact of Einstein’s relativity theories (...) and quantum mechanics. A recurring theme is the contrasting attitudes taken towards “action at a distance” causal influences by both philosophers and scientists. (shrink)

In French mechanical treatises of the nineteenth century, Newton’s second law of motion was frequently derived from a relativity principle. The origin of this trend is found in ingenious arguments by Huygens and Laplace, with intermediate contributions by Euler and d’Alembert. The derivations initially relied on Galilean relativity and impulsive forces. After Bélanger’s Cours de mécanique of 1847, they employed continuous forces and a stronger relativity with respect to any commonly impressed motion. The name “principle of relative (...) motions” and the very idea of using this principle as a constructive tool were born in this context. The consequences of Poincaré’s and Einstein’s awareness of this approach are analyzed. Lastly, the legitimacy and significance of a relativity-based derivation of Newton’s second law are briefly discussed in a more philosophical vein. (shrink)

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)

In this paper I challenge the usual interpretations of Newton's and Leibniz's views on the nature of space and the relativity of motion. Newton's ‘relative space’ is not a reference frame; and Leibniz did not regard space as defined with respect to actual enduring bodies. Newton did not subscribe to the relativity of intertial motions; whereas Leibniz believed no body to be at rest, and Newton's absolute motion to be a useful fiction. A more accurate rendering of the (...) opposition between them, I argue, leads to a wholly different understanding of Leibniz's theory of space, one which is not susceptible to the objections Newton had raised against Descartes regarding the representation of motion. This in turn suggests a new approach for contemporary theory of space, one which neither hypostatizes space nor tries to reduce it to relations among actual things. * This work was generously supported by the National Endowment for the Humanities, with a Fellowship for College Teachers and Independent Scholars (FB-26897-89), and also by a sabbatical leave from my institution, Middlebury College.

Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinian special relativity is interpreted as a response to the threat of discontinuity implied by the Michelson-Morley experiment, a challenge to classical objectivism that Einstein sought to (...) counteract. We see that Einstein's efforts to banish discontinuity ultimately fall into the “black hole” predicted in his general theory of relativity. The unavoidable discontinuity that haunts Einstein's theory is also central to quantum mechanics. Here too the attempt has been made to manage discontinuity, only to have this strategy thwarted in the end by the intractable problem of quantum gravity. The irrepressible discontinuity manifested in the phenomena of modern physics proves to be linked to a merging of subject and object that flies in the face of Cartesian philosophy. To accommodate these radically non-classical phenomena, a new philosophical foundation is called for: phenomenology. Phenomenological philosophy is elaborated through Merleau-Ponty's concept of depth and is then brought into focus for use in theoretical physics via qualitative work with topology and hypercomplex numbers. In the final part of this paper, a detailed summary is offered of the specific application of topological phenomenology to quantum gravity that was systematically articulated in The Self-Evolving Cosmos (Rosen 2008a).

This is an excellent short selection whose aim is to illustrate the guiding principles of Newton’s natural philosophy. It is divided into four sections, namely the method of natural philosophy, its principles, its relations with natural theology, and finally some typical examples of the problem it studies. Many of the passages chosen are from letters or other relatively inaccessible works. By means of clever editing, a unity and coherence is achieved which almost makes this little book a new treatise. It (...) gives those who are unfamiliar with the actual writings of Newton a chance to study his system at first-hand, thus gaining an insight into the towering intellectual structure called “Newtonian physics”, a structure which dominated not only the science, but also to some extent the philosophy, of two centuries.

John Granville's first book is unique on several counts. First, it's not simply a history of science, but rather a history of our evolving unerstanding of motion. It's unique in the detailed explanations given to common scientific riddles-explanations aimed to help students avoid catastrophic collisions with these concepts in college. It's unique in that it resents the philosophies on which the major scientific paradigm shifts rest. It's unique in its presentation from Thomas Kuhn's point of view (i.e., his concept of (...) world view and paradigm shifts as presented in his classic work The Structure of Scientific Revolutions). The book begins with an informal discussion of Kuhn's notion of world view, and various concepts relevant to his thesis concerning the nature of scientific revolutions; but, the Discovery of Motion proper begins with ancient Egyptian and Greek preparations for Aristotle (here the dialectic of Parmenides and Plato are given special attention). A survey of Aristotle and his science of motion follows (i.e., his theory of nature and natural philosophy). Included in this part of the book are the works of such notables as Archimedes and Ptolemy. The Copernican revolution, including the works of Galileo, Kepler and Newton is, of course, presented from the viewpoint of Kuhn's paradigm shift. Four chapters concerning Newtonian motion are the highlight of the first half of the book. It is here Granville's original aim, of explaning puzzling scientific phenomena to young students, is realized-but now this material serves another purpose. These chapters not only clarify Newton's world view but expose phenomena that were virtually invisible to the peripatetics...and will eventually expose reasons for the ambivalence and frustration that accompany scientific revolutions. Granville then turns to philosophical developments that led to our modern view of the world. This part of the book covers the evolution of empiricism from Bacon to Hume (with Descartes' rationalism thrown in for contrast). Kant's epistemology concludes this philosophical survey, deliberately leading the plot back toward the classical viewpoint. Finally, developments of the nineteenth century that led to the so-called Second Scientific Revolution are considered. The final chapter is a unique presentation of Einstein's relativity theory, where the incompatibility of this theory with Newtonian physics, and the reason why relativity must take precedence, are discussed. Granville compares the opposition to the Copernican revolution with twentieth century opposition to the Einsteinian revolution. The book reveals that, after building detailed understanding of classical Newtonian phenomena, opposition to a shift of world view is an understandable human reaction. (shrink)

In this paper I argue that reading history of physics as a contribution to history of philosophy is important for contemporary philosophy of physics. My argument centers around a particular case: special relativity versus presentism. By means of resources drawn from reading aspects of Newton's work as contributions to philosophy, I argue that there is in physics an alternative way to approach what we mean by "present" such that presentism remains an open empirical question whose refutation requires resources that (...) go beyond those of special relativity. I offer this as an example of one fruitful way in which we pursue integrated HPS. (shrink)

From late 1684 through mid-1685, Isaac Newton turned to developing and refining the conceptual foundations presupposed by his emerging physics. Analysis of his manuscripts from this period reveals that Newton’s understanding of the relativity of acceleration led him to seek a spatiotemporally invariant quantity of matter. He found two such quantities and then designed an experiment to discover their relationship. Interpreting the experiment, however, required distinguishing a new notion of force. Others have recognized the conceptual distinction between inertial and (...) gravitational mass. I show here that Newton clearly saw this distinction and that he provisionally established their equivalence. (shrink)

Today's physics has led to incredible advances in the technology we use in daily life - from cell phones and GPS systems to PET scans and more. Current theories in physics have been amazingly effective in practical terms. Yet all is far from well: the two foundational concepts in physics - Quantum Theory and General Relativity - are incompatible with each other, and observations of the universe show that our theories are incomplete - at best. While physicists have tried (...) to paper over this impasse by inventing dark matter and dark energy, they remain unobserved mysteries. Adding fuel to the fire of current crises, artificial intelligence threatens to replace our most cherished theories and procedures with arcane algorithms. Worse yet perhaps, the public understands physics poorly, either taking it for granted or fearing and rejecting it completely. Physicists dream of a new universal theory that will completely change how we see our world, much as Einstein did with relativity and Newton with gravity. Likewise, society loves the romantic notion of a single genius heroically creating a massive paradigm shift. Still, is this scenario likely today? Perhaps the next steps in physics will be incremental rather than gigantic. In Physics in Crisis, Bruno Mansoulié uses simple language, insightful examples, and his personal experience as a working physicist to address these fundamental questions and reflect on how today's crises in physics might be solved.

In this paper we argue that the primary issue in Descartes’ Principles of Philosophy, Part II, articles 1-40, is the problem of individuating bodies. We demonstrate that Descartes departs from the traditional quest for a principle of individuation, moving to a different strategy with the more modest aim of constructing bodies adequate to the needs of his cosmology. In doing this he meets with a series of difficulties, and this is precisely the challenge that Newton took up. We show that (...) Descartes’ questions and his strategy influenced not only Newton’s account of physical bodies, but also the structure of his mechanics. (shrink)

Cartesian method both organizes and impoverishes the domains to which Descartes applies it. It adjusts geometry so that it can be better integrated with algebra, and yet deflects a full-scale investigation of curves. It provides a comprehensive conceptual framework for physics, and yet interferes with the exploitation of its dynamical and temporal aspects. Most significantly, it bars a fuller unification of mathematics and physics, despite Descartes' claims to quantify nature. The work of his contemporaries Galileo and Torricelli, and of his (...) successor Newton, illustrates conceptual possibilities Descartes left aside, due to his attachment to method. (shrink)
