The ArgumentThis paper is about the context of Albert Einstein's concerns at the time of a most intense intellectual effort — his own and that of a small group of scientists concerned with classical quantum theory. I describe contemporaneous interactions and differing views about the prospects for and the significance of the First Solvay Congress of 1911 as voiced by major participants. There are two axes around which the paper evolves: the Einstein-Nernst-Lorentz dialogue and the public institutional creation of the (...) “Solvay” stage. In certain ways, this paper is about personal and institutional patronage: the working out of a difficult theoretical impasse requires individual and collective moral support. It is about the forging of the identity of a scientific problem and the personal and institutional setting, the public space, in which this problem was collectively addressed. But I also uncover heuristic playfulness and flexibility which accompanies theoretical change. (shrink)

It is a trite and often lamented fact that every academic discipline suffers from the malady of overspecialization and expertise. Who, in his scholarly experience, has not encountered technical gibberish and the jargon of the pundit? The contributors to this work have aUempted to remove the artifi­ cial barriers between these respective disciplines. The purpose of this volume is to explore the ever present links between logic, physical reality, and history. Indeed there are not two or three or four cuItures: (...) there is only one culture; our generation has lost its awareness of this. Though serious, it is not tragic. All we need is to free ourselves from the fetters of mere "technicalese" and search for a comprehensive interpretation of logical and physical theories. His'torians, logicians, physicists - all are banded in one common enterprise, namely in their desire to weave an enlightened fabric of human knowledge. It is a current, and perhaps weJcome, trend in philosophie inquiry to de-psychologize systems, methods, and theories. However, there is an equally fashionable tendency to minimize or even eschew the historical aspects of logical and physical theories, and analogously, there is a deep­ seated mistrust among physicists and cosmologists against the seemingly pure abstractions of logical formalisms.

INITIAL PROBABILITIES: A PREREQUISITE FOR ANY VALID INDUCTION* * I. INDUCTIVE REASONING AND ITS UNDERLYING ASSUMPTIONS Experience does not tell us anything ...

Proceedings and Discussion of the 1968 Salzburg Colloquium in the Philosophy of Science.

This book reports the proceedings of the International Congress on the Education of Teachers of Physics in Secondary Schools, held in Eger, Hungary, during September 1970.

Modern physics asks: how do the objects exist? This kind of question inevitably touches upon philosophy; to be precise, it involves metaphysics that traditionally deals with these problems. There are grounds to assume that a quantum object in a certain sense does not exist until it is registered. Thus, one of the conclusions says, “Photon is a photon if it is a registered photon”. This is a paraphrase of well-known Wheeler’s words about the essence of quantum phenomenon. These effects (...) cannot be understood if we come from the assumption that all existing (‘real’) and quantum objects in particular, is only being of the actual. To explain quantum mechanics phenomena we need to realize that there exists another modus of being. Quantum mechanics refers to some sort oftranscendence. Such conclusion is based not only on the analysis of the testing of Aspeckt’s experiments. The whole structure of quantum mechanics confirms it. The revision of the New European paradigm leads to the return of such conception of existence that brings us to the traditional metaphysical understanding of the being and implies its study on several levels of existence. The conclusion of this kind leads to a serious correction of the philosophical model of the world built by modern natural science. (shrink)

This is a new release of the original 1960 edition.

Although exceptionally successful in the laboratory, the standard version of quantum theory is marred as a realist-objectivist proposition because of its internal conceptual difficulties and its tension with important parts of physics—most conspicuously, relativity theory. So, to meet these challenges, in recent years at least three distinct major objectivist programs have been advanced to further quantum theory into a proper general account of material systems. Unfortunately, the resulting proposals turn out to be, for all practical purposes, empirically equivalent both (...) among themselves and against the standard version. This paper analyzes the basic issues involved in the case. It is argued that (a) the global anti-realist conclusion derived from it are fallacious, and (b) the encountered underdetermination shows how contingent upon the state of empirical knowledge talk about the “limits of science” actually is.

Discussions on physicalism, reduction, special sciences, the layered image of reality, multiple realizability, emergence, downward causation, and so forth, typically make the ontological presupposition that there is no room for new properties in the physical world. It is my purpose in this paper to explore the alternative hypothesis that there can be—and in fact are—new physical properties. In the first section, I will propose a brief analysis of the notions of property, physical property, and new physical property. In the second (...) section, I will present four general situations in which it would be plausible to speak of the existence of new physical properties. All of that will be used to evaluate the content and scope of the hypothesis of physical novelty. Finally, in the third section, I will examine certain very interesting and promising consequences of such a physical novelty in relation to some of the topics above mentioned. (shrink)

Discussions about physicalism, reduction, special sciences, the layered image of reality, multiple realizability, emergence, downward causation, etc., typically make the ontological presupposition that there is no room for new properties in the physical world. The domain of physical properties would thus have been established once and for all.

The IOth International Congress of Logic, Methodology and Philosophy of Science, which took place in Florence in August 1995, offered a vivid and comprehensive picture of the present state of research in all directions of Logic and Philosophy of Science. The final program counted 51 invited lectures and around 700 contributed papers, distributed in 15 sections. Following the tradition of previous LMPS-meetings, some authors, whose papers aroused particular interest, were invited to submit their works for publication in a collection of (...) selected contributed papers. Due to the large number of interesting contributions, it was decided to split the collection into two distinct volumes: one covering the areas of Logic, Foundations of Mathematics and Computer Science, the other focusing on the general Philosophy of Science and the Foundations of Physics. As a leading choice criterion for the present volume, we tried to combine papers containing relevant technical results in pure and applied logic with papers devoted to conceptual analyses, deeply rooted in advanced present-day research. After all, we believe this is part of the genuine spirit underlying the whole enterprise of LMPS studies. (shrink)

The report of B. M. Hessen at the I All-Union Congress of physicists. The Congress was held in Odessa from 19 to 24 August 1930. At the plenary meeting B. M. Hessen, made a report on methodological issues of quantum physics, the relationship of physics and philosophy. Mechanistic materialism in his time came to replace the scholastic physics. But he could not solve the problems of development and specificity of forms of movement. B. M. Hessen believed that (...) the development of the basic concepts of natural science (matter, space and time, motion, wave and particle, pattern and randomness) coincides with the approach of dialectical materialism.

A compilation of selected papers presented at the 1989 Charles S. Pierce International Congress Interest in Charles Sanders Peirce (1839-1914) is today worldwide. Ernest Nagel of Columbia University wrote in 1959 that "there is a fair consensus among historians of ideas that Charles Sanders Peirce remains the most original, versatile, and comprehensive philosophical mind this country has yet produced." The breadth of topics discussed in the present volume suggests that this is as true today as it was in 1959. Papers (...) concerning Peirce's philosophy of science were given at the Harvard Congress by representatives from Italy, France, Sweden, Finland, Korea, India, Denmark, Greece, Brazil, Belgium, Spain, Germany, and the United States. The Charles S. Peirce Sesquicentennial International Congress opened at Harvard University on September 5, 1989, and concluded on the 10th—Peirce's birthday. The Congress was host to approximately 450 scholars from 26 different nations. The present volume is a compilation of selected papers presented at that Congress. The philosophy of science and its logic are themes in the work of Charles Peirce that have been of greatest interest to scholars. Peirce was himself a physical scientist. He worked as an assistant at the Harvard Astronomical Observatory from 1869 to 1872 and made a series of astronomical observations there from 1872 to 1875. Solon I. Bailey says of these observations, "The first attempt at the Harvard Observatory to determine the form of the Milky Way, or the galactic system, was made by Charles S. Peirce....The investigation was of a pioneer nature, founded on scant data." Peirce also made major contributions in fields as diverse as mathematical logic and psychology. C. I. Lewis has remarked that "the head and font of mathematical logic are found in the calculus of propositional functions as developed by Peirce and Schroeder." Peirce subsequently invented, almost from whole cloth, semiotics - the science of the meaning of signs. Ogden and Richards, the British critics, say that "by far the most elaborate and determined attempt to give an account of signs and their meanings is that of the American logician C. S. Peirce, from whom William James took the idea and the term Pragmatism, and whose Algebra of Dyadic Relations was developed by Schroeder.". (shrink)

This collection of 38 papers gives a cross-section of ongoing research in philosophy of science and philosophical logic. The papers, written by active researchers in the field and published here for the first time, are drawn from around 650 papers that were contributed to the 9th International Congress of Logic, Methodology and Philosophy of Science in Uppsala, Sweden, 1991. Some of the speakers whose contributions attracted special interest were invited to contribute their papers to this volume. A few papers appear (...) here more or less as they were presented at the Congress, whereas others are expansions or elaborations of the talks given. There is one section with five papers on philosophical logic. The other papers deal with many different aspects of philosophy of science, including general methodological questions, problems of probability, induction and decision theory, and ethics of science and technology, as well as foundational problems about particular sciences. Five special sections are concerned with logic, mathematics and computer science, the physical sciences, the biological sciences, cognitive science, and linguistics, respectively. Finally, there is one section on the history of logic, methodology and philosophy of science. The book will be of interest to philosophers of science and logicians, as well as to all researchers interested in the foundations of their disciplines. (shrink)

Rudyard Kipling, the famous english author of « The Jungle Book », born in India, wrote one day these words: « Oh, East is East and West is West, and never the twain shall meet ». In my paper I show that Kipling was not completely right. I try to show the common ground between buddhist philosophy and quantum physics. There is a surprising parallelism between the philosophical concept of reality articulated by Nagarjuna and the physical concept of reality (...) implied by quantum physics. For neither is there a fundamental core to reality, rather reality consists of systems of interacting objects. Such concepts of reality cannot be reconciled with the substantial, subjective, holistic or instrumentalistic concepts of reality which underlie modern modes of thought. (shrink)

Both Aquinas and Siger were familiar with a fundamental disagreement within the earlier philosophical tradition concerning the subject of metaphysics: Is it being as being, or is it divine being? If Avicenna represented one approach to this issue, and Averroes another, both Thomas and Siger were closer to Avicenna than to Averroes in their respective solutions. Nonetheless, each resolved the issue in a distinct way. Also contested in the earlier tradition was the question of whether it belongs to physics (...) or to metaphysics to demonstrate the existence of God. Again, Avicenna represents one side on this issue, and Averroes the other. Thomas’s personal position continues to be debated by contemporary scholars, and Siger’s seems to fall between those proposed by Avicenna and Averroes. Finally, Aquinas is credited with having developed a new and unique way of accounting for the discovery of being as being, through a process known as separatio; though there are antecedents for this in Avicenna.

This is a collection of outstanding contributed papers presented at the 11th International Congress of Logic, Methodology, and Philosophy of Science (Kraków, 1999). The articles address current issues in logic, metamathematics, philosophy of language, philosophy of science, and cognitive science, as well as philosophical problems of biology, chemistry and physics. The volume will be of interest to philosophers, logicians and scientists interested in foundational problems.

I argue against the claim -- advocated by Albert Einstein, Bernard Williams, and Ted Sider, among others -- that a description is objective only if it says how the world is in itself. Instead, I argue for the claim -- inspired by comments of Niels Bohr -- that a family of descriptions is objective only if they co-vary with their respective descriptive contexts. Moreover, I claim that "there is a shared objective reality" simply means that it is possible to satisfy (...) this kind of covariance requirement. (shrink)

Il est tout à fait possible de soutenir que l’espace de Newton manque d’objectivité physique (ce qui est un corollaire de la théorie einsténienne) et néanmoins prendre tout à fait au sérieux la thèse de l’espace euclidien comme condition de possibilité de l’expérience. Condition de possibilité de l’émergence d’un sujet qui configure son monde en remettant tout point de son environnement à une métrique. Cette métrique ne serait autre que celle qui donne sens à la géométrie que l’on a appris (...) à l´école, c’est à dire, la métrique euclidienne. Tout en manquant de réalité physique, tout en n`étant pas fertile à l’heure de rendre compte de la forme de l’univers, la métrique euclidienne serait la seule modalité sous laquelle il y aurait pour l’homme une prise sur le monde. Qu’on l’appelle ou pas transcendantale, la reconnaissance de la métrique euclidienne comme condition de possibilité de l’expérience nous rapprocherait de Kant sans pour autant répudier Einstein ou Poincaré.

I attempt to define the concept of ‘living organism’. Intuitively, a living organism is a substantial entity with a capacity for certain relevant activities. But biology has discovered that living organisms have a particular compositional or microstructural nature. This nature includes carbon-based macromolecules and water molecules. I argue that such living organisms belong to a natural kind of compound physical object, viz., carbon-based living organism. My definition of a living organism encompasses both the intuitively relevant activities and the empirically discovered (...) compositional nature. The definition is designed to deal with a variety of problem cases, e.g., viruses, proteinoid microspheres, sterile organisms, suspended animation cases, and living parts of organisms. (shrink)

The paper shows epistemological, methodological and ontological peculiarities of chemistry taken as a classificatory science of materials using experimental methods. Without succumbing to standard interpretations of physical science, chemical methods of experimental investigation, classification, reference, theorizing, prediction and production of new entities are developed one by one as first steps towards a philosophy of chemistry. Chemistry challenges traditional concepts of empirical object, empirical predicate, reference frame and theory, but also the distinction commonly drawn between natural science and technology. Due to (...) its many peculiarities, I propose to treat chemistry philosophically as a special type of science, apart from other sciences. (shrink)

Sixty three papers divided into eleven sections ranging through the philosophy of logic, mathematics, physics, social sciences, history and linguistics. The conference seems to have been used primarily for summing up recent achievements or continuing well-established lines of research, rather than for developing new perspectives --R. J. B.

The emphasis in this collection is clearly on logic, and this is one reason why it lacks the overall diversity and richness of the 1960 Stanford volume. However, the eight sections do contain much interesting material; in the mathematical logic section Kochen and Specker continue their study of logics appropriate for quantum theory, Vaught presents several new results about the Löwenheim-Skolem theorem, and Büchi studies second-order ordinal theory from the viewpoint of automata theory; the section on foundations of mathematical theories (...) contains papers on higher-order logic by Kaplan and Montague, model theory and ultra-products by Keisler, definability in set theory by Lévy. The topic of the justification of formal theories was the essential topic of the philosophy of logic section: an especially interesting paper is that of A. Robinson in which the present state of Hilbertean Formalism is analyzed, and in which the notion of potential truth is formalized. The section on the philosophy of science contains a single paper, by Hesse, on metaphor and explanation; Braithwaite, Hintikka, Jeffrey, and Kyburg contribute to a lively section on probability and induction; the section on methodology in physical science takes as topics the theory of relativity, causality, and irreversibility. The last two sections, on the philosophy of the life sciences, and on history of logic and philosophy of science, contain, respectively, papers by Davidson and Suppes on meaning and concept formation, and essays by Church and Geach on existential import historically considered and intentionality among the medievals. The collection would have been better if more of the contributed papers had been included.—P. J. M. (shrink)

The "object theoretic operational view" suggests a new structure of physical knowledge. This view takes branches of physics as basic units. Its main concepts are primary (PIO) and secondary (SIO) ideal objects with the explicit definition of SIO through PIO and the implicit definition of PIOs within appropriate systems of statements, called a "nucleus of a branch of physics" (NBP). Within an NBP (which has a definite structure) the focus shifts from discovering "laws of nature" to definition of (...) a physical object (system) and its states, and the distinct notion "measurable" replaces the vague notion "observable". On this basis the roles of physical models and measurements within physics, as well as two types (PIO- and SIO- type) of theories, activity, and experiment are discussed, and a different junction of "realism” and "constructivism" is presented.

Fundamental notions Husserl introduced in Ideen I, such as epochè, reality, and empty X as substrate, might be useful for elucidating how mathematical physics concepts are produced. However, this is obscured in the context of Husserl’s phenomenology itself. For this possibility, the author modifies Husserl’s fundamental notions introduced for pure phenomenology, which found all sciences on the absolute Ego. Subsequently, the author displaces Husserl's phenomenological notions toward the notions operating inside scientific activities themselves and shows this using a case (...) study of the construction of noncommutative geometry. The perspective in Ideen I about geometry and mathematical physics includes points that are inappropriate to modern geometry and to modern physics, especially to noncommutative geometry and to quantum physics. The first point relates to the intuitive character of geometrical objects in Husserl. The second is linked to the notion of locality related to the notion of extension, by which Husserl characterizes the essence of physical things. The points show that the notion of empty X as a substrate, developed in “Phenomenology of Reason” in Ideen I, is helpful for considering the notions of physical reality and of geometrical space, especially reality in quantum physics and space in noncommutative geometry. The salient conclusions include the proposition that aphilosophical study of the relationship between the physical object X, which imparts a unity to what is given to sensibility, and the geometrical space X, which imparts a unity of sense to various mathematical operations, opens a reinterpretation of Husserl’s interpretation, supporting an epistemology of mathematical physics.
