This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and Berkeley between 1929 and 1932) and Herbert Feigl (who visited Harvard in the 1930-31 academic year) played a crucial role in promoting the *Wissenschaftliche Weltauffassung*, years before members of the Vienna Circle, the Berlin Group, and the Lvov-Warsaw school would seek refuge in the United States. Building on archive material from the Wiener Kreis Archiv, the (...) Harvard University Archives, and the Herbert Feigl Papers, as well as a large number of publications in American philosophy journals from the early 1930s, I reconstruct the subtle transformation of the American philosophical landscape in the years immediately preceding the European exodus. I argue that (1) American philosophical discussions about meaning and significance and (2) internal dynamics in the Vienna Circle between 1929 and 1931 significantly impacted the way in which US philosophers came to perceive logical positivism.

The paper investigates the kind of dependence relation that best portrays Machian frame-dragging in general relativity. The question is tricky because frame-dragging relates local inertial frames to distant distributions of matter in a time-independent way, thus establishing some sort of non-local link between the two. For this reason, a plain causal interpretation of frame-dragging faces huge challenges. The paper will shed light on the issue by using a generalized structural equation model analysis in terms of manipulationist counterfactuals recently applied in (...) the context of metaphysical enquiry by Schaffer (2016) and Wilson (2017). The verdict of the analysis will be that frame-dragging is best understood in terms of a novel type of dependence relation that is half-way between causation and grounding. (shrink)

This paper is about the reception of Ernst Mach by Brentano and his students in Austria. I shall outline the main elements of this reception, starting with Brentano’s evaluation, in his lectures on positivism, of Mach’s theory of sensations. Secondly, I shall comment the early reception of Mach by Brentano’s pupils in Prague. The third part bears on the close relationship that Husserl established between his phenomenology and Mach’s descriptivism. I will then briefly examine Mach’s contribution to the controversy on (...) gestalt qualities. The fifth part bears on Stumpf’s debate with Mach on psychophysical relations and I shall conclude on Husserl’s criticism of Mach’s alleged logical psychologism. (shrink)

This paper aims at understanding the concept of convention in mechanics as a notion transferred from the field of jurisprudence. This enables us to clarify it as a new epistemic category having a pertinent role in the transformation of mechanics in the nineteenth century. Such understanding permits a separation from linguistic and arbitrary conventions, thus highlighting its epistemic features and not transforming fundamental principles into mere arbitrary agreements. After addressing the main references in the literature discussing the role of convention (...) in mechanics, we analyze its classical use as a concept originating from law. Then we explain its use by Carl G. Jacobi, Ferdinand F. Reech, and J. Henri Poincaré. Here we also show how their uses conform to the features analyzed regarding conventions in jurisprudence. Finally, we try to explain how the use of this concept, among other factors, contributed to the transformation of mechanics. (shrink)

In his project of going beyond the “modern worldview,” Hiromatsu Wataru attached great importance to Ernst Mach’s philosophical thought and Einstein’s theory of relativity as challenging the premises of modern philosophy, which he characterized as substantialist and bound by the subject / object schema. This paper surveys Hiromatsu’s analysis of Mach’s phenomenalist element-monism, specifically his critique of Mach’s insufficient break with modern philosophy; his inquiry into Einstein’s relativity theory with a focus on its intersubjective cognitive structure; and the way he (...) extends his views on these themes to a general ontological-epistemological theory of the “fourfold structure.” Finally, it examines questions about Hiromatsu’s arguments regarding the tension between the dimensions of synchronic structure and structuring movement. An earlier version of this paper can be found as “Philosophers” in John T. Blackmore, Itagaki Ryōichi, and Tanaka Setsuko, eds., Ernst Mach’s Influence Spreads, 425–76. (shrink)

The conventional interpretation that Pierre Duhem condemned outright any type of thought experiment in Ernst Mach’s sense should be, at least in large part, rejected. Although Duhem placed particular emphasis on the perils of thought experiments that Mach had overlooked or at least underestimated, he retained the core idea of Mach’s theory, according to which thought experiments cannot break free from the ultimate authority of real-world experiments. This similarity between Duhem’s and Mach’s views about thought experiments is not the only (...) one. Just as there was in Duhem’s criticism of “expériences fictives” a tendency leading him to give voice to one of Mach’s basic empiricist claims, so also there was in Mach’s interpretation of thought experiments a tendency in the direction of Duhem’s conventionalism. If Mach’s and Duhem’s conceptions of thought experiments are compared, there results an importantly similar, although not identical, tension that should properly be taken into account in the more general comparison between Mach and Duhem.

The problem analysed in this paper is whether we can gain knowledge by using valid inferences, and how we can explain this process from a model-theoretic perspective. According to the paradox of inference (Cohen & Nagel 1936/1998, 173), it is logically impossible for an inference to be both valid and its conclusion to possess novelty with respect to the premises. I argue in this paper that valid inference has an epistemic significance, i.e., it can be used by an agent to (...) enlarge his knowledge, and this significance can be accounted in model-theoretic terms. I will argue first that the paradox is based on an equivocation, namely, it arises because logical containment, i.e., logical implication, is identified with epistemological containment, i.e., the knowledge of the premises entails the knowledge of the conclusion. Second, I will argue that a truth-conditional theory of meaning has the necessary resources to explain the epistemic significance of valid inferences. I will explain this epistemic significance starting from Carnap’s semantic theory of meaning and Tarski’s notion of satisfaction. In this way I will counter (Prawitz 2012b)’s claim that a truth-conditional theory of meaning is not able to account the legitimacy of valid inferences, i.e., their epistemic significance. (shrink)

hilosophy of history and history of philosophy of science make for an interesting case of “mutual containment”: the former is an object of inquiry for the latter, and the latter is subject to the demands of the former. This article discusses a seminal turn in past philosophy of history with an eye to the practice of historians of philosophy of science. The narrative turn by Danto and Mink represents both a liberation for historians and a new challenge to the objectivity (...) of their findings. I will claim that good sense can be made of “working historical veins of possibility” (contrary to how the phrase was originally intended) and that already Danto and Mink provided materials (although they did not quite advertise them as such) to assuage fears of a constructivist free-for-all.

There have recently appeared claims that the influence Heinrich Hertz exerted over Wittgenstein's later work was far more abiding than previously recognised. I critically evaluate such claims by Gordon Baker and Allan Janik. I first show that Hertz was indeed concerned with the same feature, clarity, which often exercised Wittgenstein. But I then argue that Wittgenstein should not be seen as having adopted the conception of philosophical method, which Hertz deployed in The Principles of Mechanics. I show that Hertz ‘clarifies’ (...) the concept of force only in the sense that he alters that concept, and that he is not using the sort of ‘contrastive’ methods characteristic of Wittgenstein's later works.

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

Discussions of the relation between pragmatism and logical empiricism tend to focus on the period when the logical empiricists found themselves in exile, mostly in the United States, and then attempt to gauge the actual extent of their convergence. My concern lies with the period before that and the question whether pragmatism had an earlier influence on the development of logical empiricism, especially on the thought of the former members of the “first” Vienna Circle. I argue for a substantially qualified (...) affirmative answer. (shrink)

This paper responds to the generous comments by Alexander Klein and Cheryl Misak on my “American Pragmatism and the Vienna Circle: The Early Years”. First, besides offering some clarification of my original thesis, I argue that Jerusalem was not liable to the anti-Spencerian criticisms by James that Klein adduces in the course of defending James against the charge of psychologism. Then I investigate the impact of Wittgenstein’s Ramsey-derived pragmatism, importantly foregrounded by Misak, on the Vienna Circle and argue that it (...) was mainly limited to Schlick but not recognized as pragmatist, also leaving unaffected the impact of James’s pragmatism on Frank, Hahn and Neurath specified in my original paper. That said, Klein’s and Misak’s comments add significantly to our understanding of long-neglected transatlantic philosophical connections in the early twentieth century. (shrink)

The determination of inertia by matter is looked at in general relativity, where inertia can be represented by affine or projective structure. The matter tensor T seems to underdetermine affine structure by ten degrees of freedom, eight of which can be eliminated by gauge choices, leaving two. Their physical meaning---which is bound up with that of gravitational waves and the pseudotensor t, and with the conservation of energy-momentum---is considered, along with the dependence of reality on invariance and of causal explanation (...) on conservation.

Existe una aparente incongruencia entre, por una parte, la gran distancia que Ludwig Wittgenstein detectaba entre sus objetivos filosóficos y los de los pragmatistas y, por otra, el acercamiento que posteriormente se ha producido en la historia de la recepción de la filosofía wittgensteiniana entre esta y el (neo)pragmatismo. Con afán de tratar de arrojar algo de luz sobre tal discordancia, nos ocuparemos aquí de modo privilegiado en las reflexiones de Wittgenstein en torno al cumplimiento de reglas (es decir, sobre (...) el fenómeno de la normatividad), y la solución que a este respecto dan diversos autores pragmatistas, para comprobar si efectivamente es similitud o más bien radical disparidad (o tal vez, si se nos permite la manida referencia, simplemente un «parecido de familia») la que se da entre el proyecto filosófico wittgensteiniano y el pragmatista. Pero el objetivo fundamental de este escrito no es, con todo, una simple determinación exegética de cuáles son las verdaderas intenciones de unos y otros (esfuerzo intencionalista que combinaría bastante mal, por lo demás, con las nociones tanto wittgensteinianas como pragmatistas acerca de la normatividad); sino que de lo que se tratará será principalmente de ver qué tesis resultan, a la postre, más plausibles si queremos hacernos con una idea filosóficamente coherente del fenómeno de lo normativo: si las de un pragmatismo estereotipado (que Wittgenstein repudia ferviente), o bien las de un pensamiento que se quiere no filosófico (como el del propio vienés), o bien las mucho más matizadas consideraciones procedentes del neopragmatismo.

We propose a solution to the problem of time for systems with a single global Hamiltonian constraint. Our solution stems from the observation that, for these theories, conventional gauge theory methods fail to capture the full classical dynamics of the system and must therefore be deemed inappropriate. We propose a new strategy for consistently quantizing systems with a relational notion of time that does capture the full classical dynamics of the system and allows for evolution parametrized by an equitable internal (...) clock. This proposal contains the minimal temporal structure necessary to retain the ordering of events required to describe classical evolution. In the context of shape dynamics (an equivalent formulation of general relativity that is locally scale invariant and free of the local problem of time) our proposal can be shown to constitute a natural methodology for describing dynamical evolution in quantum gravity and to lead to a quantum theory analogous to the Dirac quantization of unimodular gravity.

Inwieweit vermag sich der ehemalige explanative Erfolg nicht mehr anerkannter Theorien auf die Geltung derjenigen Teilaussagen, die Nachfolgetheorien übernommen haben, zu stützen? Zur Klärung dieser Fragestellung können die Ergebnisse von Machs Untersuchung zur mechanistischen Auffassung des Energieerhaltungssatzes herangezogen werden. Indem er sich in seiner Kritik an den ontologischen Annahmen des Mechanismus auf die Wissenschaftsgeschichte beruft, steht er einer heutigen realismuskritischen Argumentation nahe. Andererseits mißt er den hypothesenfreien Theoriebestandteilen einen Geltungscharakter zu, der in seinem Wahrheitsanspruch durchaus mit einer heutigen realistischen Behauptung (...) theorieübergreifender Bestände der wissenschaftlichen Erkenntnis vergleichbar ist. Daß Mach mit einer quer zur gegenwärtigen Terminologie liegenden Analyse einen Beitrag zur Entschärfung gegenwärtiger Kontroversen leistet, läßt eine erneute Vergegenwärtigung der Schrift von 1872 und den sich daran anschließenden Überlegungen Machs lohnenswert erscheinen.

A new form of skepticism is described, which holds that objectivity and understanding are incompossible ideals of modern science. This is attributed to Weyl, hence its name: Weylean skepticism. Two general defeat strategies are then proposed, one of which is rejected.

During the second decade of the 20th century Hans Kleinpeter, an Austrian scholar devoted to the development of the modern science, published some brief papers on Nietzsche’s thought. Kleinpeter has been one of the main upholders of Mach’s epistemology and probably the first who connected his ideas with the philosophy of Nietzsche. In his book on Der Phänomenalismus (1913) he described a new world view that arose in the 19th century, a perspective that ‒ according to him ‒ completely contrasted (...) the mechanistic and metaphysical world view of the old school of scientific inquiry. The main outcome of the scientists whose name was related with this perspective (e.g. Clifford, Maxwell, Kirchoff and, obviously, Mach himself) has been the refusal of the absolute value of any “truth”. Kleinpeter’s statements on this topic are a good example of the rising of a Scientific Philosophy, whose development involved many scientists and thinkers that later set up the Verein Ernst Mach and the Wiener Kreis. On the other hand, his interest on Nietzsche is a relevant case of reception of the latter’s thought, that Kleinpeter puts into the context of the contemporary epistemology. In fact, he considers Nietzsche as one of the main upholders of the phenomenalistic world view, and states that he «took part at the same renewal of philosophical investigation that arose from the latest results of scientific inquiry» during the 19th century. A renewal whose main outcomes has been presented by John Stallo in his book on The Concepts and Theories of Modern Physics (1881), which Kleinpeter translated in German and published in 1901. According to Kleinpeter, in Nietzsche’s writings (mostly unpublished) one can find a theory of knowledge quite close to the one presented by both Mach and the new born Pragmatism, i.e. the complete refusal of an absolute truth and, therefore, the development of an antimetaphysical world view. In my paper I’ll discuss the main statements presented by Kleinpeter on this topic and show which of Nietzsche’s ideas has actually been in compliance with the main outcomes of late 19th century science. Thus, I’ll carry out a reconstruction of an unfamiliar side of the first period of reception of the philosophy of Nietzsche and its relevance to the development of a new (scientific) world view.

Hermann Weyl succeeded in presenting a consistent overarching analysis that accounts for symmetry in material artifacts, natural phenomena, and physical theories. Weyl showed that group theory is the underlying mathematical structure for symmetry in all three domains. But in this study Weyl did not include appeals to symmetry arguments which, for example, Einstein expressed as “for reasons of symmetry”. An argument typically takes the form of a set of premises and rules of inference that lead to a conclusion. Symmetry may (...) enter an argument both in the premises and the rules of inference, and the resulting conclusion may also exhibit symmetrical properties. Taking our cue from Pierre Curie, we distinguish two categories of symmetry arguments, axiomatic and heuristic; they will be defined and then illustrated by historical cases. (shrink)

Pierre Duhem's often unrecognized influence on twentieth-century philosophy of science is illustrated by an analysis of his significant if also largely unrecognized influence on Albert Einstein. Einstein's first acquaintance with Duhem's La Théorie physique, son objet et sa structure around 1909 is strongly suggested by his close personal and professional relationship with Duhem's German translator, Friedrich Adler. The central role of a Duhemian holistic, underdeterminationist variety of conventionalism in Einstein's thought is examined at length, with special emphasis on Einstein's deployment (...) of Duhemian arguments in his debates with neo-Kantian interpreters of relativity and in his critique of the empiricist doctrines of theory testing advanced by Schlick, Reichenbach, and Carnap. Most striking is Einstein's 1949 criticism of the verificationist conception of meaning from a holistic point of view, anticipating by two years the rather similar, but more famous criticism advanced independently by Quine in Two Dogmas of Empiricism.

Discussions of the metaphysical status of spacetime assume that a spacetime theory offers a causal explanation of phenomena of relative motion, and that the fundamental philosophical question is whether the inference to that explanation is warranted. I argue that those assumptions are mistaken, because they ignore the essential character of spacetime theory as a kind of physical geometry. As such, a spacetime theory does notcausally explain phenomena of motion, but uses them to construct physicaldefinitions of basic geometrical structures by coordinating (...) them with dynamical laws. I suggest that this view of spacetime theories leads to a clearer view of the philosophical foundations of general relativity and its place in the historical evolution of spacetime theory. I also argue that this view provides a much clearer and more defensible account of what is entailed by realism concerning spacetime. (shrink)

The physicist's conception of space-time underwent two major upheavals thanks to the general theory of relativity and quantum mechanics. Both theories play a fundamental role in describing the same natural world, although at different scales. However, the inconsistency between them emerged clearly as the limitation of twentieth-century physics, so a more complete description of nature must encompass general relativity and quantum mechanics as well. The problem is a theorists' problem par excellence. Experiment provide little guide, and the inconsistency mentioned above (...) is an important problem which clearly illustrates the intermingling of philosophical, mathematical, and physical thought. In fact, in order to unify general relativity with quantum field theory, it seems necessary to invent a new mathematical framework which will generalise Riemannian geometry and therefore our present conception of space and space-time. Contemporary developments in theoretical physics suggest that another revolution may be in progress, through which a new kind of geometry may enter physics, and space-time itself can be reinterpreted as an approximate, derived concept. The main purpose of this article is to show the great significance of space-time geometry in predetermining the laws which are supposed to govern the behaviour of matter, and further to support the thesis that matter itself can be built from geometry, in the sense that particles of matter as well as the other forces of nature emerges in the same way that gravity emerges from geometry. Scientific research is not a process of steady accumulation of absolute truths, which has culminated in present theories, but rather a much more dynamic kind of process in which there are no final theoretical concepts valid in unlimited domains.

The theory of knowledge in early twentieth-century Anglo American philosophy was oriented toward phenomenally described cognition. There was a healthy respect for the mind-body problem, which meant that phenomena in both the mental and physical domains were taken seriously. Bertrand Russell's developing position on sense-data and momentary particulars drew upon, and ultimately became like, the neutral monism of Ernst Mach and William James. Due to a more recent behaviorist and physicalist inspired "fear of the mental", this development has been down-played (...) in historical work on early analytic philosophy. Such neglect assumes that the "linguistic turn" is a proper and permanent effect of twentieth-century philosophy, an assumption that distorts early analytic historiography, and begs a substantive philosophical question about thought and cognition.

There are philosophers who deny that causal relations actually exist in nature, arguing that they are merely a product of our perspective as beings capable of intentional actions. In this paper I briefly explain this thesis and consider that it needs to be complemented with a basic non-causal ontological perspective which can account for phenomena taken as causal; I then describe what seems to be a good candidate for such an ontology and finally conclude, however, that it cannot dispense with (...) the concept of causation and that therefore is not the kind of ontology that anti-realism about causal relations requires.

Modern commentators have doubts about the authenticity and cogency of the early propositions of Archimedes’ On Equilibrium of Planes Book 1. Ernst Mach famously said that the proof of Prop. 6, the so-called law of the lever, assumes what is to be proven. Comparing the initial text in Heiberg’s modern edition (1881, 1913) to the first propositions in Eutocius’ commentary on EP 1, J. L. Berggren ([1976]. ‘Spurious Theorems in Archimedes’ Equilibrium of Planes: Book I’, Archive for History of Exact (...) Sciences 16.2 (1976), 87–103.) claimed that the propositions up through Proposition 3 of the standard modern edition are schoolbook additions written by an ancient author inferior to Archimedes. The present paper argues for the logical connectedness of Postulates 1–5 to Props. 1–6, by means of a detailed examination of the course of the argument and a re-examination of Eutocius’ remarks. The paper reinterprets the role of the empirical in the early propositions and offers a reading of the contribution of Archimedes’ mechanics to the method of EP 1. (shrink)

The movement known as Deutsche Physik (German physics) evolved hand in hand with National Socialism. It represented a marginal but vocal group of German scientists and science scholars who profiled themselves as defenders of “Aryan” science and called for the elimination of the “Jewish spirit” that they saw as epitomized by Albert Einstein’s relativity theory and as dominating the natural sciences, even in Nazi Germany. This infamous movement is most associated with the Nobel laureate physicists Philipp Lenard and Johannes Stark, (...) who founded it and gave it its initial political impetus during the early years of the Third Reich. However, in its main and final phase, between 1937 and 1943, the movement was no longer led by Lenard and Stark but by the philosopher of science Hugo Dingler (1881–1954) and his Munich-based circle. Tracing the development of his career until 1937, this article examines how Dingler came to play this role both despite and because of the significant differences between his and the better known Lenard-Stark strand of Deutsche Physik. Special attention is paid to Dingler’s subversive use of theoretical principles—particularly his framing of his work as a radical search for certainty—to advance the movement’s antiscientific agenda.

Why did nineteenth‐century German historians and physicists habitually warn against vices that they believed philosophers in particular embodied: speculation, absence of common sense, and excessive systematizing? Drawing on a rich array of sources, this article interprets this vice‐charging as a rhetorical practice aimed at delineating empirical research from Naturphilosophie and Geschichtsphilosophie as practiced in the heyday of German Idealism. The strawman of “the philosopher” as invoked by historians and physicists served as a negative model for strongly empiricist scholars committed to (...) virtues like precision, thoroughness, and conscientiousness. In their historical narratives, historians and physicists consistently depicted philosophy either as a relic from the past or as a phase that they had virtuously left behind. This boundary work was central to the self‐positioning of both history and physics, which makes clear that the persona of the philosopher mattered not only to philosophers but also to scholars in adjacent disciplines.

We present a new metaphysical framework for physics that is conceptually clear, ontologically parsimonious, and empirically adequate. This framework relies on the notion of self-subsisting structure, that is, a set of fundamental physical elements whose individuation and behavior are described in purely relational terms, without any need for a background spacetime. Although the specification of the fundamental elements of the ontology depends on the particular physical domain considered---and is thus susceptible to scientific progress---, the empirically successful structural features of the (...) framework are preserved through theory change. The kinematics and dynamics of these self-subsisting structures are technically implemented using the theoretical framework of Pure Shape Dynamics, which provides a completely relational physical description of a system in terms of the intrinsic geometry of a suitably defined space called shape space.

The paper presents a detailed interpretation of Edgar Wind’s Experiment and Metaphysics, a unique work on the philosophy of physics which broke with the Neo-Kantian tradition under the influence of American pragmatism. Taking up Cassirer’s interpretation of physics, Wind develops a holistic theory of the experiment and a constructivist account of empirical facts. Based on the concept of embodiment which plays a key role in Wind’s later writings on art history, he argues, however, that the outcomes of measurements are contingent. (...) He then proposes an anti-Kantian conception of a metaphysics of nature. For him, nature is an unknown totality which manifests itself in discrepancies between theories and experiment, and hence the theory formation of physics can increasingly approximate the structure of nature. It is shown that this view is ambiguous between a transcendental, metaphysical realism in Kant’s sense and an internal realism in Putnam’s sense. Wind’s central claim is that twentieth century physics offers new options for resolving Kant’s cosmological antinomies. In particular, he connected quantum indeterminism with the possibility of human freedom, a connection that Cassirer sharply opposed. (shrink)

The `problem of time' is a cluster of interpretational and formal issues in the foundations of general relativity relating to both the representation of time in the classical canonical formalism, and to the quantization of the theory. The purpose of this short chapter is to provide an accessible introduction to the problem.

A number of philosophers have argued that causation is not an objective feature of the microphysical world but rather is a perspectival phenomenon that holds only between “coarse-grained” entities such as those that figure in the special sciences. This view seems to pose a problem for arguments for physicalism that rely on the alleged causal completeness of physics. In this paper, I address this problem by arguing that the completeness of physics has two components, only one of which is causal. (...) These two components of completeness can be used in an argument for physicalism that is supported by strong inductive evidence even in the absence of microphysical causation. (shrink)

Relational mechanics is a gauge theory of classical mechanics whose laws do not govern the motion of individual particles but the evolution of the distances between particles. Its formulation gives a satisfactory answer to Leibniz’s and Mach’s criticisms of Newton’s mechanics: relational mechanics does not rely on the idea of an absolute space. When describing the behavior of small subsystems with respect to the so called “fixed stars”, relational mechanics basically agrees with Newtonian mechanics. However, those subsystems having huge angular (...) momentum will deviate from the Newtonian behavior if they are described in the frame of fixed stars. Such subsystems naturally belong to the field of astronomy; they can be used to test the relational theory. (shrink)

This paper deals with Ágnes Heller’s suggestion, in A Theory of Modernity (1999), to ascribe to science a central role in the ongoing development of modernity. As we shall argue, this is not merely a historical issue but, rather, a historical-philosophical one that entails the problem of defining modernity, science and technology and their mutual interconnections. As for modernity, according to Heller, it is a free developmental project without any foundations other than freedom itself. In particular, the evolution of science (...) and technology is one of its main developmental tendencies. Science, she argues, has become the dominant world explanation while technological thought is the corresponding dominant (but not unique) imaginary institution. Her attempt to isolate the essential cultural features of science-technology owes much to Habermas’s analyses of the 1960s on the technocratic developments of contemporary societies legitimized through an ideological employment of science. Like Habermas, Heller embraces an instrumental and problem-solving conception of technology and ‘normal’ science which appears questionable, however, in the light of conclusions on the intrinsic creativity of the science-technology interface deriving from historical epistemology and an externalist history of science. Considerations and examples derived from the recent agenda of historical epistemology could integrate Heller’s philosophical and cultural analysis of the role of science in modernity while challenging some of her assumptions.

In this contribution, I comment on Raffaella Campaner’s defense of explanatory pluralism in psychiatry (in this volume). In her paper, Campaner focuses primarily on explanatory pluralism in contrast to explanatory reductionism. Furthermore, she distinguishes between pluralists who consider pluralism to be a temporary state on the one hand and pluralists who consider it to be a persisting state on the other hand. I suggest that it would be helpful to distinguish more than those two versions of pluralism – different understandings (...) of explanatory pluralism both within philosophy of science and psychiatry – namely moderate/temporary pluralism, anything goes pluralism, isolationist pluralism, integrative pluralism and interactive pluralism. Next, I discuss the pros and cons of these different understandings of explanatory pluralism. Finally, I raise the question of how to implement or operationalize explanatory pluralism in scientific practice; how to structure the “genuine dialogue” or shape “the pluralistic attitude” Campaner is referring to. As tentative answers, I explore a question-based framework for explanatory pluralism as well as social-epistemological procedures for interaction among competing approaches and explanations.

ArgumentEinstein's initial fame came in late 1919 with a dramatic breakthrough in his general theory of relativity. Through a remarkable confluence of events and circumstances, the mass media soon projected an image of the photogenic physicist as a bold new revolutionary thinker. With his theory of relativity Einstein had overthrown outworn ideas about space and time dating back to Newton's day, no small feat. While downplaying his reputation as a revolutionary, Einstein proved he was well cast for the role of (...) mild-mannered scientific genius. Yet fame demanded its price. Surrounded by social and economic unrest in Berlin, he was caught between two worlds, one struggling to be born, another refusing to die. Far from withdrawing, he threw himself into the political fray to become a symbol for international reconciliation during the early Weimar Republic. A decade later, his public image acquired another layer when he re-emerged as a Stoic sage and selfless humanitarian, a quasi-religious figure who saw himself as a modern-day Spinoza. Focusing on events of this period and the role of the German media in portraying them, this essay highlights the scientific and political undercurrents that drew Einstein into the public eye at a critical juncture in European history. Its broader aim is to show the import of these themes within the context of the vast literature on Einstein as well as the larger historiography of science. (shrink)

In order to make reliable predictions in any region of human activity, it is necessary to distinguish clearly what is based on experience and what is a construction of intellect. The theory of knowledge developed in the present paper is an attempt to devise a set of axioms that demarcate experience, as the only source of our knowledge of the external world, from the ideas, scientific models, and theories by means of which the scientific predictions are made. After a discussion (...) of the causality in relation to the laws of nature, the axioms of the expounded theory are formulated in the formalism of set theory. The theory is then applied to some problems in physics to demonstrate its usefulness. (shrink)

Old and recent ideas concerning the nature of time are reviewed, starting from Mach's refusal of Newton's absolute time. Many experiments show that the slowing down of moving clocks is a real phenomenon. Such must then also be the so-called “twin paradox,” which owes its name to its evident incompatibility with the philosophy of relativism (not to be confused with the theory of relativity). The Lorentz reformulation of special relativity started by postulating physical effects of the ether, but accepted Einstein's (...) clock synchronization. Only because of this Lorentz could not understand the advantages of an easily deducible different theory. As stressed by Popper, one of the main problems of the usual approach is the introduction of a superdeterministic universe. Recent results obtained by the author show that a theory is possible, based on relative time but on absolute simultaneity, in which the conceptual difficulties of relativity are avoided. (shrink)
