I think it will be agreed that there is a domain of investigation where physics and philosophy overlap. There are branches of philosophy which do not approach the subject-matter of physics, and a great part of the work of practical and theoretical physicists is not aimed at extending our knowledge of the fundamental nature of things; but questions which concern the general interpretation of the physical universe and the significance of physical law are claimed by (...) both parties. I suppose that ideally the physicist should be allowed to elucidate his own universe up to a point, and then hand it over to the philosopher to ascertain its exact status in relation to a wider outlook.

Examples of theory development in quantum field theory and in S-matrix theory are related to three questions of interest to the philosophy of science. The first is the central role of highly abstract, mathematical models in the creation of theories. Second, the process of creation and justification actually used make it plausible that a successful theory is equally well characterized as being stable against attack rather than as being objectively correct. Lastly, the issue of the reality of theoretical (...) entities is discussed in light of this representation of theory generation and selection. (shrink)

In 1912, Henri Poincaré published an argument which apparently shows that the hypothesis of quanta is both necessary and sufficient for the truth of Planck''s experimentally corroborated law describing the spectral distribution of radiant energy in a black body. In a recent paper, John Norton has reaffirmed the authority of Poincarés argument, setting it up as a paradigm case in which empirical data can be used to definitively rule out theoretical competitors to a given theoretical hypothesis. My goal (...) is to dispute Norton ''s claim that there is no theoretical underdetermination problem arising between classical physics and early quantum theory. The strategy I use in defending my view is to adopt a suggestion made by Jarrett Leplin and Larry Laudan on how to assess the relative merits of competing theoretical alternatives, where each alternative has an equal capacity to save the phenomena. In the course of the paper, I distinguish between two branches of classical physics: classical mechanics and classical electromagnetism. The former is claimed by Norton and Poincaré to be determinately ruled out by the black body evidence; and it is the former that I argue is compatible with this evidence. (shrink)

The concept of mass is one of the most fundamental notions in physics, comparable in importance only to those of space and time. But in contrast to the latter, which are the subject of innumerable physical and philosophical studies, the concept of mass has been but rarely investigated. Here Max Jammer, a leading philosopher and historian of physics, provides a concise but comprehensive, coherent, and self-contained study of the concept of mass as it is defined, interpreted, and applied (...) in contemporary physics and as it is critically examined in the modern philosophy of science. With its focus on theories proposed after the mid-1950s, the book is the first of its kind, covering the most recent experimental and theoretical investigations into the nature of mass and its role in modern physics, from the realm of elementary particles to the cosmology of galaxies.The book begins with an analysis of the persistent difficulties of defining inertial mass in a noncircular manner and discusses the related question of whether mass is an observational or a theoretical concept. It then studies the notion of mass in special relativity and the delicate problem of whether the relativistic rest mass is the only legitimate notion of mass and whether it is identical with the classical mass. This is followed by a critical analysis of the different derivations of the famous mass-energy relationship E = mc2 and its conflicting interpretations. Jammer then devotes a chapter to the distinction between inertial and gravitational mass and to the various versions of the so-called equivalence principle with which Newton initiated his Principia but which also became the starting point of Einstein's general relativity, which supersedes Newtonian physics. The book concludes with a presentation of recently proposed global and local dynamical theories of the origin and nature of mass.Destined to become a much-consulted reference for philosophers and physicists, this book is also written for the nonprofessional general reader interested in the foundations of physics.

In response to Cushing it is urged that the vicissitudes of quantum field theory do not press towards a nonrealist attitude towards the theory as strongly as he suggests. A variety of issues which Redhead raises are taken up, including photon localizability, the wave-particle distinction in the classical limit, and the interpretation of quantum statistics, vacuum fluctuations, virtual particles, and creation and annihilation operators. It is urged that quantum field theory harbors an unacknowledged inconsistency connected with the fact that the (...) zero point energy has observable consequences, while to avoid infinities it must be "thrown away". Finally, Redhead's conception of ephemerals is pressed and the paper concludes with the suggestion that the particle concept largely drops out of quantum field theory. (shrink)

It is easy to show that in many natural axiomatic formulations of physical and even mathematical theories, there are many superfluous concepts usually assumed as primitive. This happens mainly when these theories are formulated in the language of standard set theories, such as Zermelo–Fraenkel’s. In 1925, John von Neumann created a set theory where sets are definable by means of functions. We provide a reformulation of von Neumann’s set theory and show that it can be used to formulate physical and (...) mathematical theories with a lower number of primitive concepts very naturally. Our basic proposal is to offer a new kind of set-theoretic language that offers advantages with respect to the standard approaches, since it doesn’t introduce dispensable primitive concepts. We show how the proposal works by considering significant physical theories, such as non-relativistic classical particle mechanics and classical field theories, as well as a well-known mathematical theory, namely, group theory. This is a first step of a research program we intend to pursue. (shrink)

The paper explicates the stages of the author’s philosophical evolution in the light of Kopnin’s ideas and heritage. Starting from Kopnin’s understanding of dialectical materialism, the author has stated that category transformations of physics has opened from conceptualization of immutability to mutability and then to interaction, evolvement and emergence. He has connected the problem of physical cognition universals with an elaboration of the specific system of tools and methods of identifying, individuating and distinguishing objects from a scientific theory domain. (...) The role of vacuum conception and the idea of existence (actual and potential, observable and nonobservable, virtual and hidden) types were analyzed. In collaboration with S.Crymski heuristic and regulative functions of categories of substance, world as a whole as well as postulates of relativity and absoluteness, and anthropic and self-development principles were singled out. Elaborating Kopnin’s view of scientific theories as a practically effective and relatively true mapping of their domains, the author in collaboration with M. Burgin have originated the unified structure-nominative reconstruction (model) of scientific theory as a knowledge system. According to it, every scientific knowledge system includes hierarchically organized and complex subsystems that partially and separately have been studied by standard, structuralist, operationalist, problem-solving, axiological and other directions of the current philosophy of science. 1) The logico-linguistic subsystem represents and normalizes by means of different, including mathematical, languages and normalizes and logical calculi the knowledge available on objects under study. 2) The model-representing subsystem comprises peculiar to the knowledge system ways of their modeling and understanding. 3) The pragmatic-procedural subsystem contains general and unique to the knowledge system operations, methods, procedures, algorithms and programs. 4) From the viewpoint of the problem-heuristic subsystem, the knowledge system is a unique way of setting and resolving questions, problems, puzzles and tasks of cognition of objects into question. It also includes various heuristics and estimations (truth, consistency, beauty, efficacy, adequacy, heuristicity etc) of components and structures of the knowledge system. 5) The subsystem of links fixes interrelations between above-mentioned components, structures and subsystems of the knowledge system. The structure-nominative reconstruction has been used in the philosophical and comparative case-studies of mathematical, physical, economic, legal, political, pedagogical, social, and sociological theories. It has enlarged the collection of knowledge structures, connected, for instance, with a multitude of theoreticity levels and with an application of numerous mathematical languages. It has deepened the comprehension of relations between the main directions of current philosophy of science. They are interpreted as dealing mainly with isolated subsystems of scientific theory. This reconstruction has disclosed a variety of undetected knowledge structures, associated also, for instance, with principles of symmetry and supersymmetry and with laws of various levels and degrees. In cooperation with the physicist Olexander Gabovich the modified structure-nominative reconstruction is in the processes of development and justification. Ideas and concepts were also in the center of Kopnin’s cognitive activity. The author has suggested and elaborated the triplet model of concepts. According to it, any scientific concept is a dependent on cognitive situation, dynamical, multifunctional state of scientist’s thinking, and available knowledge system. A concept is modeled as being consisted from three interrelated structures. 1) The concept base characterizes objects falling under a concept as well as their properties and relations. In terms of volume and content the logical modeling reveals partially only the concept base. 2) The concept representing part includes structures and means (names, statements, abstract properties, quantitative values of object properties and relations, mathematical equations and their systems, theoretical models etc.) of object representation in the appropriate knowledge system. 3) The linkage unites a structures and procedures that connect components from the abovementioned structures. The partial cases of the triplet model are logical, information, two-tired, standard, exemplar, prototype, knowledge-dependent and other concept models. It has introduced the triplet classification that comprises several hundreds of concept types. Different kinds of fuzziness are distinguished. Even the most precise and exact concepts are fuzzy in some triplet aspect. The notions of relations between real scientific concepts are essentially extended. For example, the definition and strict analysis of such relations between concepts as formalization, quantification, mathematization, generalization, fuzzification, and various kinds of identity are proposed. The concepts «PLANET» and «ELEMENTARY PARTICLE» and some of their metamorphoses were analyzed in triplet terms. The Kopnin’s methodology and epistemology of cognition was being used for creating conception of the philosophy of law as elaborating of understanding, justification, estimating and criticizing legal system. The basic information on the major directions in current Western philosophy of law (legal realism, feminism, criticism, postmodernism, economical analysis of law etc.) is firstly introduced to the Ukrainian audience. The classification of more than fifty directions in modern legal philosophy is suggested. Some results of historical, linguistic, scientometric and philosophic-legal studies of the present state of Ukrainian academic science are given. (shrink)

The two main points of this contribution are the following: (1) Applied mathematical theories might complement physical theories in an essential way; some applied mathematical theories allow us to understand phenomena we are unable to explain by resorting to physical theories alone, (2) In the case of social sciences it might be necessary to account for examined phenomena by resorting to the idea of goal-oriented activity (the causal approach typical for natural science might be unsatisfactory). Weinberg's idea of grand reductionism (...) ignores the two above mentioned facts and hence overestimates the foundational role of physics and its methodology. (shrink)

IT has been some time now since anyone professing himself to be a phenomenalist has characterized physical objects as ‘logical constructions out of sense-data’ in the strict sense of this expression. If he is to be justified in applying the expression in the strict sense, the phenomenalist must demonstrate that there exists a relation of mutual entailment between a statement implying the existence of a physical object and a statement referring exclusively to our ‘sense-experiences’. As a matter of historical fact, (...) no phenomenalist has ever succeeded in doing this; and it is now generally acknowledged, even by those who still wish to adhere to some form of a phenomenalistic analysis of physical object statements, that there are difficulties in principle why the reductivist programme of the early phenomenalists cannot be carried out. The modern-day phenomenalist, in an attempt to avoid the pitfalls in his predecessors’ position, tends to regard physical objects as fruitful and convenient theoretical constructions for interpreting and predicting our sense-experiences. Thus, although still committed to the view that physical objects are ‘constructed’ out of sense-data, he is no longer committed to the thesis of a strict logical equivalence between statements about objects and statements about experiences. Professor A J Ayer, perhaps the foremost exponent of this type of view today, put the matter this way not so long ago. (shrink)

If you wish to learn from the theoretical physicist anything about the methods which he uses, I would give you the following piece of advice: Don't listen to his words, examine his achievements.

This chapter explores some fundamental consequences of the correspondence between physical process and computations. Most physical questions may be answerable only through irreducible amounts of computation. Those that concern idealized limits of infinite time, volume, or numerical precision can require arbitrarily long computations, and so be considered formally undecidable. The behavior of a physical system may always be calculated by simulating explicitly each step in its evolution. Much of theoretical physics has, however, been concerned with devising shorter methods (...) of calculation that reproduce the outcome without tracing each step. Computational irreducibility is common among the systems investigated in mathematics and computation theory, but it may well be the exception rather than the rule, since most physical questions may be answerable only through irreducible amounts of computation.

The history and philosophy of science are destined to play a fundamental role in an epoch marked by a major scientific revolution. This ongoing revolution, principally affecting mathematics and physics, entails a profound upheaval of our conception of space, space–time, and, consequently, of natural laws themselves. Briefly, this revolution can be summarized by the following two trends: by the search for a unified theory of the four fundamental forces of nature, which are known, as of now, as gravity, (...) electromagnetism, and strong and weak nuclear forces; by the search for new mathematical concepts capable of elucidating and therefore explaining such a relationship. In fact, the first search is essentially dependent on the second; that is to say, that in order for a new theory of physics to come to light, the development of a deeper geometric theory capable of explaining the structure of space–time on a quantum scale appears to be necessary. On careful consideration, we notice that both of these developments converge in the direction of a unitary and fundamental tendency of modern science—which is the geometrization of theoretical physics and of natural sciences. This new emergent situation carries within it a profound conceptual change, affecting the way in which relations are conceived of, first and foremost, between mathematics and physics. This new paradigm can be summed up by the intimately interdependent points: the immense variety of physical phenomena and of natural forms follows from the equally infinite variety of geometric and topological objects that can be made out in space and from which space is made up; the second point, which ensues from the former one and which is of great historical and epistemological significance, is that mathematics is involved in rather than applied to phenomena. In other words, phenomena are effects that emerge from the geometrical structure of space–time. There is no doubt that this new conception of the relationship between the universe of mathematical ideas and objects and the world of natural phenomena is the true scientific revolution of our century, of great conceptual importance, and consequently, capable of changing our view of science and of nature at one and the same time. It is all at once of a scientific, philosophical and aesthetic order. (shrink)

Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the detection of the Higgs particle and gravitational waves, and the failure to detect supersymmetry where many expected to find it, question the validity (...) of certain philosophical assumptions common among theoretical physicists, inviting us to engage in a clearer philosophical reflection on scientific method.

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

As an illustration of the complexities involved in connecting physics and molecular biology at the nanoscale, in this paper I discuss two case studies from nanoscience. The first examines the use of a biological structure to build nanostructures in a controlled way. The second discusses the attempt to build a single molecular wire, and then decide whether such a wire is indeed conducting. After presenting the central features of each case study, I examine the role played in them by (...) microscopic imaging, the different styles of reasoning involved, and the various theoretical, methodological, and axiological differences. I conclude by arguing that, except for the probe microscopes that are used, there is very little in common between the two cases. At the nanoscale, physics and molecular biology seem to meet in a non-unified way. (shrink)

Vaihinger... shows that thought is primarily a biological function turned into a conscious art. It is an art of adjustment, whose chief instrument is the construction of fictions by which men may manage to live. Thought is to be tested not by correspondence to an objective reality (that fiction is neatly disposed of) nor by its mirroring in consciousness an objective external world. Thought is to be tested by its fruits. The constructions of thought are not copies of or transcripts (...) of reality; they are programs, guess-work plans; possible programs for operation. Their validity is to be measured not by verisimilitude but by value. The fruits of thought are not "true," but especially where they are false, it may be important to act as if they were true... Vaihinger's chief originality consists in his defining of fictions and his distinction of fictions from hypotheses on the one hand, and from dogmatisms on the other. An hypothesis is a tentative discovery about the universe; a fiction is a deliberate, often clearly false and internally contradictory invention of thought... Evolution is the hypothesis that man is descended from the lower animals. We assume that we can indirectly turn to the remote facts which would justify that hypothesis. But the concept of infinity in the calculus, the atom and the ether in physics, the economic man in Adam Smith, are deliberate self-contradictory fictions, and fictions at variance with all experience. But though they are not only imaginary, false to the reality they allegedly represent and logically incoherent, they nevertheless facilitate thought and proper action. They are vital lies, human conveniences. They are the faiths, the palpably false faiths, the clearly useful falsities by which we live... The discovery that fictions were fictions has led, in the past, says Vaihinger, to an abandonment of them, and a turning to other fictions believed to be truer. Pathetic and foolish adventure! What the race needs is more faith in its own effective imaginations. The myths that it has told itself, the world pictures that it has made, are not to be dismissed because they are found to be creations of the imagination. They tally with no world and they carry the canker of logical inconsistency within them. The important thing is their utility; their human scope and mortal relevance. If we ceased making fictions, we should cease altogether to be. Let us beware to plunge from fruitful fictions to less fruitful ones that masquerade as truths and are really dogmatisms.

Dr. (...) Feigl was the director of the Center.In a preface to the first volume in the series, Professors Feigl and Michael Scriven noted the extensive concern of the Center with "the meaning of theoretical concepts as defined by their locus in the 'nomological net' and the related rejection of the reductionist forms of operationism and positivism." In this volume, several contributors are again concerned with philosophical, logical, and methodological problems of psychology. As before, some papers deal with broad philosophical issues, others with more specific problems of method or interpretation.

"Psychiatry and Philosophy of Science" explores conceptual issues in psychiatry from the perspective of analytic philosophy of science. Through an examination of those features of psychiatry that distinguish it from other sciences - for example, its contested subject matter, its particular modes of explanation, its multiple different theoretical frameworks, and its research links with big business - Rachel Cooper explores some of the many conceptual, metaphysical and epistemological issues that arise in psychiatry. She shows how these pose (...) interesting challenges for the philosopher of science while also showing how ideas from the philosophy of science can help to solve conceptual problems within psychiatry. Cooper's discussion ranges over such topics as the nature of mental illnesses, the treatment decisions and diagnostic categories of psychiatry, the case-history as a form of explanation, how psychiatry might be value-laden, the claim that psychiatry is a multi-paradigm science, the distortion of psychiatric research by pharmaceutical industries, as well as engaging with the fundamental question whether the mind is reducible to something at the physical level. "Psychiatry and Philosophy of Science" demonstrates that cross-disciplinary contact between philosophy of science and psychiatry can be immensely productive for both subjects and it will be required reading for mental health professionals and philosophers alike.

This book discusses the basic foundations of theoretical biology. Contrary to the objects of theoretical physics, the biological object contains a kind of ontological duality and refers to a fundamental wholeness of a living system. The rational interpretation of wholeness is considered by the author as a true basis for fundamental principles of development of theoretical biology and for understanding its link to physics, to psychology, and to semiotics. The rational holistic approach in application to (...) theoretical biology can be substantiated through the clarification of internal logic of organization and description of biological systems. This logic will provide an understanding of the place of life in the Universe. The main goal of this book is to introduce the view that in the potentially infinite system of human knowledge, a proper clarification of the place of Man in the Universe is possible only via understanding of the phenomenon of life.

The question of what ontological insights can be gained from the knowledge of physics (keyword: ontic structural realism) cannot obviously be separated from the view of physics as a science from an epistemological perspective. This is also visible in the debate about 'scientific realism'. This debate makes it evident, in the form of the importance of perception as a criterion for the assertion of existence in relation to the 'theoretical entities' of physics, that epistemology itself is (...) 'ontologically laden'. This is in the form of the assumption that things (or entities) in themselves exist as such and such determined ones (independent of cognition, autonomously). This ontological assumption is not only the basis of our naïve understanding of cognition, but also its indispensable premise, insofar as this understanding is a fundamentally passive, 'receptive' one. Accordingly, just as 'perception' is the foundation, ('objective') description is the aim of cognition, that which cognition is about. In this sense, our idea of cognition and our idea of the things are inseparably linked. Without the ontological premise mentioned we just would not know what cognition is, but it is basically just a kind of image that we have in our minds (an assumption that helps us understand 'cognition'). Epistemology not only shares this basic assumption (which it also shares with metaphysics), but it revolves (unlike metaphysics) entirely around it by making the idea and demand of 'certainty' a condition of 'real' knowledge. As 'certainty' is a subjective criterion this entails the 'remodelling' of the real, holistic cognitive situation (to which metaphysics adheres) into a linear subject-object-relation (which results in the strict 'transcendence' of the objects). And it also establishes, due to its 'expertise' in matters of cognition, the 'primacy of epistemology' over all other sciences. Now, on closer inspection, however, the expertise of epistemology seems not all that dependable, because it basically consists only of paradigms which, from the point of view of the holism of the real cognitive situation itself, are nothing more than relatively simplistic interpretations of this situation. However, we do not yet know what another conception of cognition might look like (which is not surprising given the high rank of the phenomenon of cognition in the hierarchy of phenomena according to their complexity). 'Certainty' as a criterion of cognition is thus excluded from the outset, and thus the linear relational model of cognition appears as what it is, a gross distortion of the real, holistic cognitive situation. The significance of this argumentation with regard to physics is that the linear epistemological model of cognition itself is a major obstacle to an adequate epistemological understanding of physics. This is because it is fixed 'a priori' to an object-related concept of cognition, and to 'description' as the only mode of ('real') cognition. But physics (without questioning our naïve notion of cognition on the level of epistemology) simply works past it and its basic assumptions. Its cognitive concept (alias heuristic) is fundamentally different from that of metaphysics. The acceptance of the real, holistic cognitive situation is, in my opinion, the condition for an adequate understanding of physics' heuristic access to objects, its transcendental, generalizing cognitive concept, as well as its ontological relevance and dimension of its own.

Within the philosophy of science, the realism debate has been revitalised by the development of forms of structural realism. These urge a shift in focus from the object oriented ontologies that come and go through the history of science to the structures that remain through theory change. Such views have typically been elaborated in the context of theories of physics and are motivated by, first of all, the presence within such theories of mathematical equations that allow straightforward representation (...) of the relevant structures; and secondly, the implications of such theories for the individuality and identity of putative objects. My aim in this talk is to explore the possibility of extending such views to biological theories. An obvious concern is that within the context of the latter it is typically insisted that we cannot find the kinds of highly mathematised structures that structural realism can point to in physics. I shall indicate how the model-theoretic approach to theories might help allay such concerns. Furthermore, issues of identity and individuality also arise within biology. Thus Dupre has recently noted that there exists a ‘General Problem of Biological Individuality’ which relates to the issue of how one divides ‘massively integrated and interconnected’ systems into discrete components. In response Dupre advocates a form of ‘Promiscuous Realism’ that holds, for example, that there is no unique way of dividing the phylogenetic tree into kinds. Instead I shall urge serious consideration of those aspects of the work of Dupre and others that lean towards a structuralist interpretation. By doing so I hope to suggest possible ways in which a structuralist stance might be extended to biology. (shrink)

The modern theoretical physicist is a strange creature. Perhaps in every age the theoretical physicist has seemed so to his contemporaries who took the trouble to observe and think about him. There seems, for example, something almost too magical in the uncanny way in which he pulls a brand new atomic particle out of a theory, a way that reminds us of a rabbit being produced out of a hat. This is usually done in an off-hand manner with (...) a considerable amount of patter of a highly abstract symbolic character but with a few words inserted in the right places for the benefit of the experimental physicist and a final prediction that if the experimenter does thus and so in the laboratory he will find a certain result. No wonder the observer marvels when the answer comes out right. But as he thinks further he is inclined to wonder whether it is necessary or desirable for the details of the process which led to the result to be so unintelligible. For unintelligible they seem to be to a great many people who are directly concerned with their understanding, to the people who for years have been laboring under the belief that they are engaged in the task of finding out how Nature works. What is this curious process whose whole task, according to one distinguished exponent of it, is merely to predict experimental results, and what is its future likely to be? These are the questions we are setting for ourselves in the present discussion. It is unlikely that the answers given here will satisfy everybody, but it is reasonably certain that nobody who aspires to an interest in science can fail to attach some meaning to them whether or not he agrees.

Recent publications by several leading philosophers of chemistry have focused on the definition, scope, utility, and nomenclature of issues dealing with acidity and basicity. In this paper, molecular orbital theory is used to explain all acid–base reactions, concluding that the interaction of the highest occupied molecular orbital (HOMO) of one substrate, “the base,” with the lowest unoccupied molecular orbital (LUMO) of a second substrate, “the acid,” determines the reactivity of such systems. This paradigm provides an understanding of all acid–base reactions (...) as well as other reactions which, on the surface, may not seem like acid–base reactions but which have fundamental underpinnings of that kind of chemistry. Rather than being unable to determine a unified understanding of acidity and basicity as suggested in the philosophy of chemistry literature, we propose that acidity and basicity fit securely in a classification of many other reactions that, using classical chemistry knowledge, pre-quantum chemistry, would not be possible. We strongly support the use of all scientific knowledge and experience in the development of the ideas in the philosophy science. We further suggest increased interactions between philosophers of science and scientists, so that all scholars benefit from the values, knowledge, and perspectives of other disciplines. (shrink)

Through an examination of those features of psychiatry that distinguish it from other sciences - for example, its contested subject matter, its particular modes of explanation, its multiple different theoretical frameworks, and its research links with big business - Rachel Cooper explores some of the many conceptual, metaphysical and epistemological issues that arise in psychiatry. She shows how these pose (...) interesting challenges for the philosopher of science while also showing how ideas from the philosophy of science can help to solve conceptual problems within psychiatry. Cooper's discussion ranges over such topics as the nature of mental illnesses, the treatment decisions and diagnostic categories of psychiatry, the case-history as a form of explanation, how psychiatry might be value-laden, the claim that psychiatry is a multi-paradigm science, the distortion of psychiatric research by pharmaceutical industries, as well as engaging with the fundamental question whether the mind is reducible to something at the physical level. "Psychiatry and Philosophy of Science" demonstrates that cross-disciplinary contact between philosophy of science and psychiatry can be immensely productive for both subjects and it will be required reading for mental health professionals and philosophers alike.

A theoretical physicist and feminist theorist, Karen Barad elaborates her theory of agential realism, a schema that is at once a new epistemology, ontology, and ethics.

What happens when the Dalai Lama meets with five leading physicists and a historian? This book documents their fascinating discussions about theoretical quantum physics and Buddhist philosophy.

The following questions arising in connection with the géométrisation of modern physics are discussed: is the physical theory a bicomponent one or everything can be reduced to space? Whether the hypothesis of the macroscopic nature of space and time deals with the theoretical or empirical structure of physical theory? Is there géométrisation of quanta or quantisation of geometry?

This paper aims to show that the development of Feyerabend’s philosophical ideas in the 1950s and 1960s largely took place in the context of debates on quantum mechanics. In particular, he developed his influential arguments for pluralism in science in discussions with the quantum physicist David Bohm, who had developed an alternative approach to quantum physics which (in Feyerabend’s perception) was met with a dogmatic dismissal by some of the leading quantum physicists. I argue that Feyerabend’s arguments for (...) class='Hi'>theoretical pluralism and for challenging established theories were connected to his objections to the dogmatism and conservatism he observed in quantum physics. However, as Feyerabend gained insight into the physical details and historical complexities which led to the development of quantum mechanics, he gradually became more modest in his criticisms. His writings on quantum mechanics especially engaged with Niels Bohr; initially, he was critical of Bohr’s work in quantum mechanics, but in the late 1960s, he completely withdrew his criticism and even praised Bohr as a model scientist. He became convinced that however puzzling quantum mechanics seemed, it was methodologically unobjectionable – and this was crucial for his move towards ‘anarchism’ in philosophy of science. (shrink)

The paper examines critically some recently published views by Ramsey on the contrast between ab initio and parametrized theories. I argue that, all things being equal, ab initio calculations are indeed regarded more highly in the physics and chemistry communities. A case study on density functional approaches in theoretical chemistry is presented in order to re‐examine the question of ab initio and parametrized approaches in a contemporary context.

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

A series of essays contrasting contemporary microphysics and its philosophic implications with classical physics' concern for macroscopic phenomena. De Broglie examines the evidence, theoretical and empirical, which forced him to abandon classical concepts, such as causal necessity, in favor of the quantum physics he helped found. The translation omits some parts of the original, including a valuable chapter on Bergson, which is merely summarized.--D. S.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The New Physics and Cosmology: Dialogues with the Dalai LamaPaul O. IngramThe New Physics and Cosmology: Dialogues with the Dalai Lama. By Arthur Zajonic. Oxford: Oxford University Press, 2004. 245 pp.Over the years there have occurred several "Life and Mind Conferences" that seek to explore the intersection between the natural sciences and Buddhism, particularly, but not limited to, Tibetan Buddhist tradition. As far as I know, (...) this series of conferences represents the most systematic effort to dialogically engage Buddhist thought and practice with the natural sciences to date. The New Physics and Cosmology is one of a number of published Buddhist-science dialogues to emerge from the Life and Mind Conferences. Its focus is contemporary quantum physics and scientific cosmology in conversation with Buddhist cosmology and is based on a conference held in Dharmasala 27–31 October 1997.Along with the Dalai Lama, the major participants in this dialogue were David Ritz Finkelstein, who teaches physics at the Georgia Institute of Technology and edits the International Journal of Theoretical Physics; George Greenstein, Sidney Dillon Professor of Astronomy at Amherst College; Peter Hut, professor of physics and interdisciplinary studies at the Institute for Advanced Study at Princeton University; Thupten Jinpa, who has served as the Dalai Lama's principal English translator since 1985; B. Allan Wallace, who trained for many years in Buddhist monasteries in India and Switzerland and is one of the Buddhist pioneers of the Buddhist-science dialogue; Tu Wei-Ming, who directs the Harvard-Yenching Institute and is professor of Chinese History and Philosophy at Harvard; Arthur Zajonc, professor of physics at Amherst College, whose research focuses on the experimental foundations of quantum physics and the relation between science and the humanities; and Anton Zeilinger, director of the Institute for Experimental Physics in Austria and professor of physics at the University of Innsbruck from 1990 to 1999.One of the remarkable features in these dialogues is that in spite of the Dalai [End Page 180] Lama's rather limited knowledge of contemporary quantum physics and cosmology, his questions to the participating scientists go very quickly to the philosophical and religious issues and challenges all religious worldviews must take seriously to remain relevant in the twenty-first century. His explanations of Tibetan Buddhist cosmology and doctrine, especially the epistemology Nagarjuna and the doctrine of sunyata or "Emptiness" as possible correlations with what the natural sciences are revealing about nature, are among the clearest Buddhist discussions in this regard I have read. One might also say that the scientists were very adept in the art of upaya in the manner in which they related their knowledge of very abstract and theoretical scientific issues to the levels of experience of their nonscientific dialogue partners. In particular, the experimental foundations of quantum physics and relativity theory were presented very thoroughly, in ways nonscientist participants could comprehend.Finally, these dialogues are not merely a series of lengthy conversations about supposed parallels between contemporary science and Buddhist teaching and practice. There is no claim that "Buddhism" is a "scientific" religious tradition, as often assumed by writers, both Buddhist and non-Buddhist, who have a tendency to read Western Enlightenment assumptions into Buddhist history. Instead, these conversations are motivated by the search for an alternative epistemological foundation for developing physical theories that could also be relevant to social, philosophical, and religious issues that the natural sciences as such are unable to address. For example, B. Alan Wallace assumes what Ian Barbour describes as an "independence model" in his understanding of the relation between science and Buddhism. Thus for Wallace and the other Buddhist participants, the natural sciences give us objective knowledge about physical processes but do not give us knowledge of an objective world. He then concludes that the function of scientific theories is to make natural events intelligible for the purpose of developing technologies that improve the quality of life. But science has very little, if anything, to say about "absolute truth," which he as a Buddhist names "Emptiness."Clearly, Wallace's interpretation of the natural sciences is based on his appropriation of the "two truth" epistemology that originated with the second century Indian Buddhist logician Nagarjuna. Nagarjuna also... (shrink)
