Eine weit verbreitete Auffassung über die wissenschaftlichen Naturverständnisse besagt, dass ihre historische Entwicklung von einer zunehmenden Abgrenzung gegenüber der Magie begleitet gewesen sei. Ursprünglich eng mit der Magie verbunden, hätten sich die wissenschaftlichen Naturverständnisse in einem langwierigen Prozess immer weiter von der Magie entfernt, bis sie ihre heutige amagische Gestalt erhalten hätten. Mein Beitrag diskutiert einige Argumente zur Stützung dieser, wie ich meine, plausiblen Auffassung. / A whitespread view of the natural sciences holds that their historical development was (...) accompanied by a constantly widening gap between them and magic. Originally closely bound up with magic, the sciences are supposed to have distanced itself from it in a long-drawn-out process, until they attained their present magic-free form. This essay discusses some arguments in support of this plausible view. (shrink)

Seit Beginn der frühen Neuzeit ist das naturwissenschaftliche Verfahren maßgeblich durch ein neues Konzept geprägt: das Konzept des experimentellen, gestalterischen Eingriffs in die Natur. Es geht nun nicht mehr darum, eine Geschichte der "freien und ungebundenen Natur" (Bacon) zu erzählen, die in ihrem eigenen Lauf belassen und als vollkommene Bildung betrachtet wird. Es geht vielmehr darum, der "gebundenen und bezwungenen Natur" (Bacon) vermittels der experimentellen Tätigkeit des Menschen die Geheimnisse zu entreißen. Diese technisch-praktische Konzeption grenzt sich explizit von den klassischen (...) kontemplativen Wissenschaftsvorstellungen der Antike ab. Wie es Kant paradigmatisch in Bezug auf Bacon formuliert hat, ist diese "Revolution der Denkart" maßgeblich durch ein gewandeltes Verständnis des Verhältnisses des Menschen zur Natur geprägt. Der Mensch als Experimentator hat für Kant nicht mehr die "Qualität eines Schülers", der sich passiv von der Natur belehren läßt und an ihrem "Leitbande" (Kant) gegängelt wird. Seine neu gewonnene Autorität verleiht ihm vielmehr den Status eines Richters, der nun die Natur nötigen kann, auf gestellte Fragen zu antworten. Die Laborforschung der modernen Naturwissenschaft ist von den Formen der alten Naturwissenschaft so weit entfernt, daß sie den Vorwurf auf sich zog, sie untersuche Artekakte, aber nicht Natur. Die grundlegenden Theorien über Natur können in der Regel nur unter den künstlichen Bedingungen des Labors aufgestellt werden. Daraus darf aber nicht geschlossen werden, die anhand von Laborphänomenen aufgestellten und getesteten Theorien handelten nicht von der Natur außerhalb der Labore. Aber ihrer exakten und detaillierten Anwendung auf Prozesse außerhalb der Labore stehen eine Fülle von Schwierigkeiten entgegen. Insofern markiert das Labor sehr wohl eine Grenze exakter Naturforschung, die für den Umgang der wissenschaftlich-technischen Zivilisation mit der Natur wichtige Konsequenzen hat.

"Wir mögen an der Natur beobachten, messen, rechnen, wägen und so weiter, wie wir wollen, es ist doch nur unser Maß und Gewicht, wie der Mensch das Maß der Dinge ist." So schrieb Goethe im Jahre 1807. "Die Natur wird uns keine Sonderbehandlung gewähren, nur weil wir uns als 'Krone der Schöpfung' betrachten... Ich fürchte, sie ist nicht eitel genug, um sich an den Menschen als einen Spiegel zu klammern, in dem allein sie ihre eigene Schönheit sehen kann", schreibt der (...) Physiker Hans-Peter Dürr heute. Diesen beiden Stellungnahmen liegen sehr unterschiedliche Vorstellungen vom Verhältnis Mensch - Natur zugrunde. Wie überhaupt die Naturphilosophie von den Vorsokratikern bis in die Gegenwart die unterschiedlichsten Varianten dieser Beziehung durchgespielt hat. Dass der Mensch sich jedoch in einem weit über die alttestamentarische Vorstellungskraft hinausgehenden Maße die Natur "untertan" gemacht und dabei großräumig zerstört hat, steht außer Zweifel. Im Rahmen der ökologischen Krise muss das Verhältnis zur Natur neu überdacht werden. Das vorliegende Lesebuch, das sich auch als Studientext und Diskussionsgrundlage für Schulen und Hochschulen bestens eignet, bietet den Blick in die Geschichte der Naturphilosophie, der dafür unerlässlich ist: Die Schwierigkeiten, die heute im Umgang mit der Natur auftreten, sind vielfach auf immer noch wirksame traditionelle Naturvorstellungen zurückzuführen. Andererseits gibt es einige eigenständige, bisher noch zu wenig berücksichtigte Ansätze, die zu neuen Konzeptionen anregen können. ------------------------------------------------------------- Inhalt: Vorwort; Einführung: Traditionslinien der Naturphilosophie; Heraklit und die Atomisten Leukipp und Demokrit; Platon und Aristoteles; Christliches Naturverstehen im Mittelalter: Aurelius Augustinus, Thomas von Aquin, Jacob Böhme; Naturvorstellungen in der beginnenden Neuzeit: Galileo Galilei, Rene Descartes, Isaac Newton; Kants Naturbegriff; Goethes Naturforschung; Nachkantische Naturphilosophie: Friedrich Wilhelm Joseph Schelling, Georg Wilhelm Friedrich Hegel; Geschichte der Natur und Kritik des Naturalismus: Karl Marx, Charles Darwin, John Stuart Mill; Kritik des Substanzbegriffes, Alfred North Whitehead, Werner Heisenberg, Ilya Prigogine und Isabelle Stengers; Bibliographie.

Die Natur ist als Thema in der Phänomenologie von Husserl bis zu Schmitz wenig bearbeitet worden. Der Grund ist teilweise in der respektvollen oder auch kritischen Distanz vieler Phänomenologen zur Naturwissenschaft zu suchen, teils darin, dass es auf dem Feld der Selbstgegebenheit - Leib, Gefühl, zwischenmenschliche Beziehungen - zunächst die eigentlichen Entdeckungen zu machen galt. Selbst die Leibphilosophie wurde nicht als ein Teil einer Phänomenologie der Natur entwickelt. Doch ist der Leib nicht die Natur, die wir selbst sind? Im (...) vorliegenden Band unternehmen Forscher verschiedener Herkunft die gemeinsame Anstrengung, mit dem Thema Natur der Phänomenologie ein neues Forschungsfeld zu eröffnen. Dabei wird nicht nur an die phänomenologische Bewegung angeknüpft, sondern auch an aristotelische goethische Naturwissenschaft, soweit sie als phänomenologisch betrachtet werden kann. Damit wird die Absicht verfolgt, die Phänomenologie der Natur als eine alternative Erkenntnisweise im Unterschied zur herrschenden naturwissenschaftlich-technischen zu entwickeln. Nach der Entfaltung des Programms wird zunächst die goethische Naturwissenschaft als ein Paradigma von Naturphänomenologie dargestellt. Dann werden die Beiträge aus der phänomenologischen Bewegung (Husserl, Klages, Schmitz) durchmustert. Und schließlich werden Fallbeispiele gegenwärtiger phänomenologischer Erforschung der Natur vorgeführt. Dabei geht es einerseits um Beiträge von seiten goetheanischer Wissenschaft (Botanik und Wärmelehre), andererseits um Beispiele, die im Rahmen der Naturphilosophie entstanden sind (Phänomenologie von Wind und Wetter, Phänomenologie des eigenen Leibes als Natur, Phänomenologie der Stoffe).

Die von Helmholtz zur Begründung des Energieprinzips in der Einleitung zu seiner Schrift "Über die Erhaltung der Kraft" genannten Bedingungen der physikalischen Forschung teile Ich in zwei Gruppen. Die erste betrifft methodische und begriffliche Voraussetzungen, die zunächst unabhängig von Erfahrung gelten (1); die zweite schränkt diese Geltung ein, indem sie die Reichweite der Methode und die Bestimmung des Ziels der Forschung Erkenntnissen unterordnet, die allein in der Erfahrung gewonnen werden können (2). Nicht den allgemeinen Bedingungen der physikalischen Forschung, sondern speziellen (...) Forschungsergebnissen entnimmt Helmholtz dann die vermeintlichen Hinweise auf die mechanische, d. h. energieerhaltende Struktur der Natur (3). Dieser Argumentation entspricht es. daß er dem physikalischen Naturwissen einen, mit der Zeit abnehmenden hypothetischen Charakter zuweist(4). (shrink)

A fundamental problem in science is how to make logical inferences from scientific data. Mere data does not suffice since additional information is necessary to select a domain of models or hypotheses and thus determine the likelihood of each model or hypothesis. Thomas Bayes’ Theorem relates the data and prior information to posterior probabilities associated with differing models or hypotheses and thus is useful in identifying the roles played by the known data and the assumed prior information when making inferences. (...) Scientists, philosophers, and theologians accumulate knowledge when analyzing different aspects of reality and search for particular hypotheses or models to fit their respective subject matters. Of course, a main goal is then to integrate all kinds of knowledge into an all-encompassing worldview that would describe the whole of reality. A generous description of the whole of reality would span, in the order of complexity, from the purely physical to the supernatural. These two extreme aspects of reality are bridged by a nonphysical realm, which would include elements of life, man, consciousness, rationality, mental and mathematical abstractions, etc. An urgent problem in the theory of knowledge is what science is and what it is not. Albert Einstein’s notion of science in terms of sense perception is refined by defining operationally the data that makes up the subject matter of science. It is shown, for instance, that theological considerations included in the prior information assumed by Isaac Newton is irrelevant in relating the data logically to the model or hypothesis. In addition, the concepts of naturalism, intelligent design, and evolutionary theory are critically analyzed. Finally, Eugene P. Wigner’s suggestions concerning the nature of human consciousness, life, and the success of mathematics in the natural sciences is considered in the context of the creative power endowed in humans by God.

Psychology considered as a natural science began as Aristotelian "physics" or "natural philosophy" of the soul. C. Wolff placed psychology under metaphysics, coordinate with cosmology. Scottish thinkers placed it within moral philosophy, but distinguished its "physical" laws from properly moral laws (for guiding conduct). Several Germans sought to establish an autonomous empirical psychology as a branch of natural science. British and French visual theorists developed mathematically precise theories of size and distance perception; they created instruments to test (...) these theories and to measure visual phenomena such as the duration of visual impressions. These investigators typically were dualists who included mental phenomena within nature. (shrink)

The claim of the freedom of the will (understood as an individual who is transcendent to Nature) in the name of XXth century scientific knowledge, against the perspective of XVIIIth-XIXth century scientific materialism, is analysed and refuted in the present paper. The hypothesis of reductionism finds no obstacle within contemporary natural sciences. Determinism in classical physics is irrefutable, unless classical physics is itself refuted. From quantum mechanics, some authors argue that free will is possible because there is an (...) ontological indeterminism in the natural laws, and that the mind is responsible for the wave function collapse of matter, which leads to a choice among the different possibilities for the body. However, here I defend the opposite thesis because indeterminism does not imply free will, and because the considerations about an autonomous mind sending orders to the body is against neuroscience or evolutionary theories about human beings. The quantum theory of measurement can be interpreted without the intervention of human minds, but other fields of science cannot contemplate the mentalist scenario. A fatalistic or materialist view, which denies the possibility of a free will, makes much more sense in scientific terms. (shrink)

Chapter 3 surveys objectivity in the natural sciences. Thomas Kuhn problematized the logicist understanding of the objectivity or rationality of scientific change, providing a very different picture than that of the cumulative or step-wise progress of theoretical science. Theories often compete, and when consensus builds around one competitor it may be for a variety of reasons other than just the direct logical implications of experimental successes and failures. Kuhn pitted the study of the actual history of science against (...) what Hans Reichenbach referred to as the “logical substitutes” logicists used to reconstruct the rationality of theory change. Such substitutes were promoted to show that theory confirmation is a purely epistemic affair, where purely epistemic implies purely inferential. But where the positivists saw logical compulsion as the reason for theory change, Kuhn saw psychology in values as relevant to how theories are actually confirmed or accepted by the scientific community.

How was the hypothetical character of theories of experience thought about throughout the history of science? The essays cover periods from the middle ages to the 19th and 20th centuries. It is fascinating to see how natural scientists and philosophers were increasingly forced to realize that a natural science without hypotheses is not possible.

Objectivity, as one of the key attributes of science, has become an indispensable part of its ethos and a central theme of the philosophy of science. As such, it has been a subject of philosophical reflection by a number of authors. In our project – in which both philosophers of science and scientists participate – we examine the concept of objectivity in the natural sciences with the tools of experimental philosophy. We aim to identify specific operational dimensions of (...) objectivity, those with which current scientist actually work, thus making them accessible for further theoretical analysis and research. In this text, we present results from the first, qualitative phase of our research based on in-depth interviews and focus groups with scientists working in the Czech Republic. Further, we confront this empirical data with theoretical notions of objectivity. We also present other findings from the research and formulate hypotheses for the research’s subsequent phases.

A number of modern theologians have concluded that the rise of natural science makes it necessary to give up the idea that God acts in particular ways to affect the course of events in the world. I reply to this claim, taking up the challenge to explain what might be meant by a ”special’ act of God. There are several ways to conceive of such acts, including the possibility that God might determine what is left determinable in the structures (...) of nature, e.g., at the quantum level. I address objections to this view, and consider metaphysical puzzles that it presents. (shrink)

Psychology considered as a natural science began as Aristotelian "physics" or "natural philosophy" of the soul, conceived as an animating power that included vital, sensory, and rational functions. C. Wolff restricted the term " psychology " to sensory, cognitive, and volitional functions and placed the science under metaphysics, coordinate with cosmology. Near the middle of the eighteenth century, Krueger, Godart, and Bonnet proposed approaching the mind with the techniques of the new natural science. At nearly the same (...) time, Scottish thinkers placed psychology within moral philosophy, but distinguished its "physical" laws from properly moral laws. British and French visual theorists developed mathematically precise theories of size and distance perception; they created instruments to test these theories and to measure visual phenomena such as the duration of visual impressions. By the end of the century there was a flourishing discipline of empirical psychology in Germany, with a professorship, textbooks, and journals. The practitioners of empirical psychology at this time typically were dualists who included mental phenomena within nature. Accordingly, psychology as a natural scientific disciplines was not invented in the 18th and 19th centuries, but *remade* from the extant empirical psychology. (shrink)

Interpretation in science has gained little attention in the past because philosophers of science believed that interpretation belongs to the context of discovery or must be associated with meaning. But scientists often speak about interpretation when they report their findings. Elsewhere I have argue in favour of a pragmatic-rhetorical theory of explanation, and it is in light of this theory that I suggest we can understand interpretation in the natural sciences.

[from the publisher's website] Questions about the existence and attributes of God form the subject matter of natural theology, which seeks to gain knowledge of the divine by relying on reason and experience of the world. Arguments in natural theology rely largely on intuitions and inferences that seem natural to us, occurring spontaneously—at the sight of a beautiful landscape, perhaps, or in wonderment at the complexity of the cosmos—even to a nonphilosopher. In this book, Helen De Cruz (...) and Johan De Smedt examine the cognitive origins of arguments in natural theology. They find that although natural theological arguments can be very sophisticated, they are rooted in everyday intuitions about purpose, causation, agency, and morality. Using evidence and theories from disciplines including the cognitive science of religion, evolutionary ethics, evolutionary aesthetics, and the cognitive science of testimony, they show that these intuitions emerge early in development and are a stable part of human cognition. -/- De Cruz and De Smedt analyze the cognitive underpinnings of five well-known arguments for the existence of God: the argument from design, the cosmological argument, the moral argument, the argument from beauty, and the argument from miracles. Finally, they consider whether the cognitive origins of these natural theological arguments should affect their rationality. (shrink)

Acknowledging that Nature is one unified whole, we expect that physics and biology are intimately related. Keeping in mind that physics became an exact science with which we are already familiar with, while, apparently, we do not have at present a similar knowledge about biology, we consider how can we make useful the clarity of physics to shed light to biology. The next question will be what are the most basic categories of physics and biology. If we do not want (...) to cut laws of Nature into different parts, we obtain a constraint, and the remaining part of physics will be the input data to the equations of physics. In these terms, our question will be: if we keep biological laws intact, as indivisible units, what remains in case of biology? This approach, just because it is more fundamental, has significant consequences for philosophy, and obviously offers a new conceptual framework considering the relation between the ontopoietic principle of Anna-Teresa Tymieniecka and the biological principle. The quintessence of science, namely, the first essentially complete scientific world picture is presented in a detailed form. (shrink)

Since his Metaphysische Anfangsgründe der Naturwissenschaft was first published in 1786, controversy has surrounded Immanuel Kant’s conception of matter. In particular, the justification for both his dynamical theory of matter and the related dismissal of mechanical philosophy are obscure. In this paper, I address these longstanding issues and establish that Kant’s dynamism rests upon Leibnizian, metaphysical commitments held by Kant from his early pre-Critical texts on natural philosophy to his major critical works. I demonstrate that, throughout his corpus (...) and inspired by Leibniz, Kant endorses the a priori law of continuity of alteration as a truth of metaphysics, according to which all alterations in experience must occur gradually through all intervening degrees. The principle thus legislates against mechanical philosophy’s absolutely impenetrable atoms, as they would would involve instantaneous changes of velocity in impact. This reveals the metaphysical incoherencies in mechanical philosophy and leaves Kant’s own dynamical theory of matter, grounded on material forces, as the only viable approach to physical explanation. Subsequently, I demonstrate that Kant nevertheless made conceptual space in his system for the theoretical consideration of mechanical explanations, which makes manifest one of the positive roles that the faculty of reason can play with respect to natural science.

Soweit Engels' Position zum Geltungsanspruch der Naturwissenschaften seiner Zeit aus diesen Texten hervorgeht, kann man sie kaum als konsistent bezeichnen. Erkenntnisse, an deren Gewissheit in der Naturforschung der zweiten Hälfte des 19. Jahrhunderts nicht ernsthaft gezweifelt wurde, werden von ihm teils umstandslos übernommen, teils aber auch einer geltungskrltischen Analyse unterzogen. In weitgehender Unahängigkeit von seinen weltanschaulichen Ambitionen kommt Engels über die Untersuchung der Struktur naturwissenschaftlicher Erkenntnisprozesse zu einer bisher erst wenig beachteten und seiner Zeit vorauseilenden Einsicht in die relativen Geltungsbedingungen (...) des experimentell erzeugten Wissens. Die widersprüchliche Form,in der er seine heute noch sehr aktuelle Kritik am Wahrheitsanspruch der Naturwissenschaften vorträgt, ist der damaligen Umbruchssituation dieser Disziplinen geschuldet und gibt seinem Werk ein hohes Mass an Authentizität. In Anlehnung an Engels' Klassifizierung der Wissenschaften sollen hier die wichtigsten geltungskritischen Ansätze rekonstruiert werden. In dieser Perspektive, die seine Skepsis gegenüber den naturwissenschaftlichen Erkenntnisleistungen hervortreten lässt, erscheint die von ihm behauptete ausgezeichnete Geltung der Dialektik in einem neuen Licht: Sie ist nicht mehr die immer schon vorausgesetzte Grundannahme seiner wissenschafts- und naturtheoretischen Auffassungen, sondern Reaktion auf einen Relativismus, der aus der Reflexion über die Entwicklung der Naturforschung unabweisbar zu folgen scheint und jedes Streben nach einem wissenschaftlich fundierten, einheitlichen Naturbild zunichte macht.

Prior to the nineteenth century, those who are now regarded as scientists were referred to as natural philosophers. With empiricism, science was claimed to be a superior form of knowledge to philosophy, and natural philosophy was marginalized. This claim for science was challenged by defenders of natural philosophy, and this debate has continued up to the present. The vast majority of mainstream scientists are comfortable in the belief that through applying the scientific method, knowledge will continue to (...) accumulate, and that claims to knowledge outside science apart from practical affairs should not be taken seriously. This is referred to as scientism. It is incumbent on those who defend natural philosophy against scientism not only to expose the illusions and incoherence of scientism, but to show that natural philosophers can make justifiable claims to advancing knowledge. By focusing on a recent characterization and defense of natural philosophy along with a reconstruction of the history of natural philosophy, showing the nature and role of Schelling’s conception of dialectical thinking, I will attempt to identify natural philosophy as a coherent tradition of thought and defend it as something different from science and as essential to it, and essential to the broader culture and to civilization.

Kant's reasoning in his special metaphysics of nature is often opaque, and the character of his a priori foundation for Newtonian science is the subject of some controversy. Recent literature on the Metaphysical Foundations of Natural Science has fallen well short of consensus on the aims and reasoning in the work. Various of the doctrines and even the character of the reasoning in the Metaphysical Foundations have been taken to present insuperable obstacles to accepting Kant's claim to ground Newtonian (...) science. Gordon Brittan and Gerd Buchdahl, amongst others, have argued that Kant's stated aims in this case are not to be taken at face value, and that prior ontological commitments play a hidden but central role in Kant's special metaphysics. ;Michael Friedman has shown how Kant's stated aims can be taken seriously with his ingenious reconstruction of the Metaphysical Foundations as a demonstration of the a priori basis for our thinking bodies to be in true motion and in absolute space. However, Friedman does not address the issue of matter theory--despite the importance of the issue to Kant. I argue that a strict reading of both the stated aims and doctrines of the Metaphysical Foundations is possible, since much of Kant's reasoning about the empirical concept of matter can be explained by his views on how the construction of empirical concepts is possible. ;Kant's quasi-mathematical constructions are pivotal in Friedman's interpretation. Constructibility is Kant's criterion of acceptability for the concepts of natural science. Yet Kant notoriously fails to construct the dynamical concept of matter, and accepts this failure with an equally notorious complacency. I argue that Kant's criteria of empirical concept construction, apart from any prior ontological commitments, are enough to generate his views on matter. Kant's failure to construct the requisite concept of matter can be ascribed to a missing law of nature, a law of the relation of forces the discovery of which Kant thought imminent. I conclude that matter theory is central to the Metaphysical Foundations, but that this does not undermine Kant's stated aim of giving the a priori ground of Newtonian science. (shrink)

In spite of Ernst Cassirer’s criticisms of psychologism throughout Substance and Function, in the final chapter he issues a demand for a “psychology of relations” that can do justice to the subjective dimensions of mathematics and natural science. Although these remarks remain somewhat promissory, the fact that this is how Cassirer chooses to conclude Substance and Function recommends it as a topic worthy of serious consideration. In this paper, I argue that in order to work out the details of (...) Cassirer’s psychology of relations in Substance and Function, we need to situate it within two broader frameworks. First, I position Cassirer’s view in relation to the view of psychology and logic endorsed by his Marburg Neo-Kantian predecessors, Hermann Cohen and Paul Natorp. Second, I augment Cassirer’s early account of the psychology of relations in Substance and Function with the more mature view of psychology that he presents in The Philosophy of Symbolic Forms. By placing Cassirer’s account within these contexts, I claim that we gain insight into his psychology of relations, not just as it pertains to mathematics and natural science, but to culture as a whole. Moreover, I maintain that pursuing this strategy helps shed light on one of the most controversial features of his philosophy of mathematics and natural science, viz., his theory of the a priori.

In this paper I examine the role of optimality reasoning in Aristotle’s natural science. By “optimality reasoning” I mean reasoning that appeals to some conception of “what is best” in order to explain why things are the way they are. We are first introduced to this pattern of reasoning in the famous passage at Phaedo 97b8-98a2, where (Plato’s) Socrates invokes “what is best” as a cause (aitia) of things in nature. This passage can be seen as the intellectual ancestor (...) of Aristotle’s own principle, expressed by the famous dictum “nature does nothing in vain but always what is best for the substance from among the possibilities concerning each kind of animal” (Progression of Animals II, 704b12-18). The paper is focused around exploring three questions that arise in connection with Aristotle’s use of this optimality principle: (1) How do we understand the concept of “the best” at work in the principle? (2) How does Aristotle conceive of “the range of possibilities”? And, finally, (3) what role does optimality reasoning play in Aristotle’s natural science? Is it a special form of demonstration in which the optimality principle functions as one of its premises, or is it a heuristic device that helps uncover those causally relevant features of a natural substances that ultimately serve as middle terms in demonstrations? In the final section I return to the comparison between Plato and Aristotle and argue that, while both see the natural world as the product of an optimizing agent and while both see this assumption as licensing a pattern of reasoning that appeals to a certain conception of “the best”, they disagree fundamentally over what the optimization agent is and how it operates. Thus, despite their general agreement, it would be a mistake to think that Aristotle simply took over Plato’s use of optimality reasoning without significant modifications. (shrink)

Abstract: The paper argues that mainstream economics and mainstream philosophy of natural science had much in common during the period 1945-1965. It examines seven common features of the two fields and suggests a number of historical developments that might help explain these similarities. The historical developments include: the Vienna Circle connection, the Samuelson-Harvard-Foundations connection, and the Cold War operations research connection.

In this multi-disciplinary investigation we show how an evidence-based perspective of quantification---in terms of algorithmic verifiability and algorithmic computability---admits evidence-based definitions of well-definedness and effective computability, which yield two unarguably constructive interpretations of the first-order Peano Arithmetic PA---over the structure N of the natural numbers---that are complementary, not contradictory. The first yields the weak, standard, interpretation of PA over N, which is well-defined with respect to assignments of algorithmically verifiable Tarskian truth values to the formulas of PA under the (...) interpretation. The second yields a strong, finitary, interpretation of PA over N, which is well-defined with respect to assignments of algorithmically computable Tarskian truth values to the formulas of PA under the interpretation. We situate our investigation within a broad analysis of quantification vis a vis: * Hilbert's epsilon-calculus * Goedel's omega-consistency * The Law of the Excluded Middle * Hilbert's omega-Rule * An Algorithmic omega-Rule * Gentzen's Rule of Infinite Induction * Rosser's Rule C * Markov's Principle * The Church-Turing Thesis * Aristotle's particularisation * Wittgenstein's perspective of constructive mathematics * An evidence-based perspective of quantification. By showing how these are formally inter-related, we highlight the fragility of both the persisting, theistic, classical/Platonic interpretation of quantification grounded in Hilbert's epsilon-calculus; and the persisting, atheistic, constructive/Intuitionistic interpretation of quantification rooted in Brouwer's belief that the Law of the Excluded Middle is non-finitary. We then consider some consequences for mathematics, mathematics education, philosophy, and the natural sciences, of an agnostic, evidence-based, finitary interpretation of quantification that challenges classical paradigms in all these disciplines.

Avicenna, beside his theoretical discussions about experimentation, practically applied his experimental method to natural sciences studies such as medicine, biology, and meteorology. His theoretical discussions subsume propositions concerning the conditions under which experimental knowledge is attained, the components of this knowledge and its functions. Some of these propositions are as follows: necessity of recurrent observations for acquiring experimental knowledge, certainty plus conditional universality of such knowledge, and its role as demonstrative premises. Investigating the application of his theory in (...) natural sciences propound two new features which were not elaborated in the theoretical discussions: fallibility of experimental knowledge and necessity of systematic observation. This research, using the analytic method and referring to both philosophical and scientific works of Avicenna, clarifies that a comprehensive definition of experimentation is dependent on considering extracted points from practical application of experimental knowledge, beside its theoretical components.

This study examines the relationship between Japanese archaeology and natural science through a quantitative analysis of the two most authoritative archaeological journals and two other relevant journals in Japan. First, although previous studies have emphasized the impact of the Department of Anthropology at the University of Tokyo on the scientific aspects of Japanese archaeology, results of the present study suggest that its impact has been more limited than previously assumed. Second, while previous studies claimed that research funding by the (...) Japanese government from the latter half of the 1970s was an important factor in developing the scientific aspects of Japanese archaeology, the present study shows a result inconsistent with the claim. Finally, although I admit that the previous studies have properly captured some aspects of the relationship between Japanese archaeology and science, I conclude that we should look at the broader array of contributors to the relationship between Japanese archaeology and natural science.

Helmholtz's public reflection about the nature of the experiment and its role in the sciences is a historically important description, which also helps to analyze his own works. It is a part of his conception of science and nature, which can be seen as an ideal type of science and its goals. But its historical reach seems to be limited in an important respect. Helmholtz's understanding of experiments is based on the idea that their planning, realization and evaluation lies (...) in the hands of a person or group acting according to decisions of free will. In my opinion this idea is characteristic for the foundation of the experimental method in early modern times, not however for several forms of its present structures. Above all, the increasing technization of producing knowledge reduces the roIe of the subject in conducting experiments. My lecture consists of three parts. In its first part I would like to present a summary of Helmholtz's own theory of experiment and the change of his conception of science and nature. In the second part I would like to discuss three examples of his experimental practice, which were taken in chronological order from three different periods of his work; in the third part I would like to compare the examples with the change of his conception of science and nature.

In this paper, I draw attention to an obstacle to determining to what extent the portrait of normal science as a problem-solving activity applies outside the natural sciences.

This article explains that and how values and evaluations are unavoidably and conspicuously present within natural scientists and their sciences—and why they are definitely not “value-free”. It shows how such things can be rationally understood and assessed within the framework of formal axiology, the value theory developed by Robert S. Hartman and those who have been deeply influenced by his reflections. It explains Hartman’s highly plausible and applicable definitions of “good” and related value concepts. It identifies three basic (...) kinds of value objects and human evaluations of these, and it shows how these should be ranked or prioritized in comparative worth. Finally, throughout, it applies all of the above to what is really going on within natural scientists and their sciences. It shows how anyone, scientists included, should proceed in order to make sense of what and how they value. (shrink)

The notion of chance plays an important role in some philosophical analyses and interpretations of scientific theories. The most obvious examples of that are the theories of evolution and quantum mechanics. This notion, however seems to be notoriously vague. Its application in such analyses, more often than not refers to its common-sense understanding, which, by definition, cannot be sufficient when it comes to sound philosophical interpretations of scientific achievements. The paper attempts at formulating a ‘typology of chance’. It distinguishes eight (...) different meanings of this notion. Those meanings can be found in classical philosophical accounts of chance, in the common usage of this term, or form logical possibilities of its understanding. Subsequently, the paper points to those forms of the notion in question which may and may not be properly applied to scientific theories and ideas – given usual characteristics of natural sciences. It also shows – by the examples of particular theories mentioned above – which of the distinguished forms of the notion of chance are actually applicable in the context of these theories. (shrink)

The nature of existence, which science seeks to investigate, is dynamic as novel discoveries are constantly presented. To explain such a dynamic existence, science itself needs to be dynamic. Methodological differentiation is one way in which science expresses dynamism. Such differentiation led to the theological and the natural sciences, and conflicting views regarding the nature of existence: the theological worldview versus the natural worldview. This study is a comparison of the conflicting worldviews of the theological and cosmological (...) theories of the beginning of existence. The study compares them in an attempt to redress the conflict and encourage dialogue between the two methods for a better representation of existence. The study exposes the limits of the theological and the natural worldviews. It proposes a relationship of dialogue between them so that they transcend their individual limits and are able to grow. Dialogue involves the interchange of ideas to broaden perspectives, which leads to growth. A relationship of dialogue emphasises similarities in presuppositions, methodology and content, and exploits these to attain a greater degree of certitude. Theology and natural science can be viewed analogically as two sides of the same coin, two aspects to one reality, that can collaborate, albeit independently, to reveal a broader view of reality. They can converse through dialogue, exchange ideas and share views, even though they remain methodologically exclusive, independent worldviews. Finally, dialogue involves a transformation of reason in that it expects theologians and natural scientists to change the way they view reality. If we were to transform our reasoning into something more complete, our worldview should represent a more complete representation of existence. This means that the theologian and the scientist can, occasionally, go beyond their scope and method and push their knowledge towards progress through dialogue. This makes “transformed reason” the method of dialogue, which redresses the conflict between theology and natural science and encourages interchange between them. (shrink)

In this multi-disciplinary investigation we show how an evidence-based perspective of quantification---in terms of algorithmic verifiability and algorithmic computability---admits evidence-based definitions of well-definedness and effective computability, which yield two unarguably constructive interpretations of the first-order Peano Arithmetic PA---over the structure N of the natural numbers---that are complementary, not contradictory. The first yields the weak, standard, interpretation of PA over N, which is well-defined with respect to assignments of algorithmically verifiable Tarskian truth values to the formulas of PA under the (...) interpretation. The second yields a strong, finitary, interpretation of PA over N, which is well-defined with respect to assignments of algorithmically computable Tarskian truth values to the formulas of PA under the interpretation. We situate our investigation within a broad analysis of quantification vis a vis: * Hilbert's epsilon-calculus * Goedel's omega-consistency * The Law of the Excluded Middle * Hilbert's omega-Rule * An Algorithmic omega-Rule * Gentzen's Rule of Infinite Induction * Rosser's Rule C * Markov's Principle * The Church-Turing Thesis * Aristotle's particularisation * Wittgenstein's perspective of constructive mathematics * An evidence-based perspective of quantification. By showing how these are formally inter-related, we highlight the fragility of both the persisting, theistic, classical/Platonic interpretation of quantification grounded in Hilbert's epsilon-calculus; and the persisting, atheistic, constructive/Intuitionistic interpretation of quantification rooted in Brouwer's belief that the Law of the Excluded Middle is non-finitary. We then consider some consequences for mathematics, mathematics education, philosophy, and the natural sciences, of an agnostic, evidence-based, finitary interpretation of quantification that challenges classical paradigms in all these disciplines.

The relationship between mind and necessity is one of the major points of difficulty for the interpretation of Plato’s Timaeus. At times Timaeus seems to say the demiurge is omnipotent in his creation, and at other times seems to say he is limited by pre-existing matter. Most interpretations take one of the two sides, but this paper proposes a novel approach to interpreting this issue which resolves the difficulty. This paper suggests that in his speech Timaeus presents two hypothetical models (...) of creation, one with an omnipotent demiurge and one where he is limited by matter, so as to investigate their theoretical and empirical validity. Further, he shows that each model is ultimately an inadequate explanation of the first principles of the cosmos. Timaeus’ speech is therefore properly understood to be aporetic: it leaves its listeners aware of the difficulties inherent in the two models of creation, but without a more viable alternative.

scientific progress, natural philosophy of the Late Medieval Period is seen as playing the role of apologetics. For philosophers of science, with their repudiation of metaphysics, the task of providing a rational reconstruction of how scientific progress has occurred is nigh on impossible. Even explanations such as the Popperian and the Kuhnian strain under great difficulty and provide only partly satisfactory results. In his “Logik der Forschung” (1934) Karl Raimund Popper argues that metaphysics plays an accidental part in the (...) emergence of new scientific ideas. Correspondingly, in “Structure of Scientific Revolutions” (1962), by carrying out theoretical interpretations and classification of empirical facts without their metaphysical premises, Thomas Kuhn comes to the conclusion that natural science was formed under the influence of erroneous interpretations of Aristotelian natural philosophy presented by medieval natural philosophers. These are some of the reasons why medievalists are still made to defend late medieval natural philosophy from shallow convictions that at medieval universities nothing of any significance to contemporary science and philosophy took place at all. Seeking to render a fragment of a coherent reconstruction of the development of natural philosophy, I will investigate one idea of late medieval philosophy – the explanation of motion (impetus). The main statement of the paper holds that the ideas of late medieval natural philosophy have a decisive significance for the development of modern natural science instead of accidental or negative one. In the paper, following Aristotelian philosophical approach, premises of Jean Buridan’s theory of impetus will be exposed. Then, debates over the explanation of projectile motion are going to be presented, and finally, the necessary significance of this metaphysical idea on the modifications of natural philosophy is going to be ascertained.

In this essay it is shown that the imaginative art of scientific theorizing – at its technical best – animates Quine's philosophy as importantly as the more Spartan norms honored in his present pantheon of virtues. By drawing a contrast between the standing of theories in philosophy and theories in science, it will be shown that the speculative reaches of philosophy, along with developments in semantic theory, now oblige an internal revision of Quine's stance against meaning as it was announced (...) in “Two Dogmas of Empiricism.” So, corollary to this proposed revision, I argue that in natural philosophy, the muse of the “art of science” deserves an address along with the more Spartan norms in Quine's present philosophical pantheon. As semantic theory and analyticity thus gain a measure of philosophical tenability, Quine's holism emerges as the more central doctrine of his mature vision. (shrink)

John Wilkins and Malte Ebach respond to the dismissal of classification as something we need not concern ourselves with because it is, as Ernest Rutherford suggested, mere ‘‘stamp collecting.’’ They contend that classification is neither derivative of explanation or of hypothesis-making but is necessarily prior and prerequisite to it. Classification comes first and causal explanations are dependent upon it. As such it is an important (but neglected) area of philosophical study. Wilkins and Ebach reject Norwood Russell Hanson’s thesis that classification (...) relies on observation that is theory-laden and deny the need for aetiological assumptions and historical reconstruction to justify its arrangement. What they offer instead is a significant (albeit controversial) contribution to the philosophical literature on classification, a pre-theoretic natural classification based on the observation of patterns in data of ready-made phenomena. Their notion of ready-made phenomena rests on a conception of tacit knowledge or know-how. This is evident in their distinction between strong Theory-dependence and na ̈ıve theory-dependence. Their small t-theory-dependence permits patterns of observation that facilitate know-how but does not rely on a domain-specific explanatory theory of their aetiology. Wilkins and Ebach suggest classification differs from theory building in that it is passive (whereas theory building is active). Classification is possible just because it does not require the sieve of theory to capture classes that are ‘‘handed to you by your cognitive dispositions and the data that you observe’’ (p. 18). Finding regularities sans-theory is just something we do and can do without any prior theory about the underlying causes or origins of the resultant regularities. Luke Howard’s classification of clouds serves as an exemplar of a passive, theory-free classification system and the periodic table and the DSM help to illustrate this type of non-aetiological patterning. A recurrent theme is the nature of naturalness. For Wilkins and Ebach, the conception of naturalness is not one that is based on the generation or discovery of natural kind categories popular in both the traditional metaphysics of Mill and Wittgenstein as well as updated notions within philosophy of biology such as Boyd’s Homeostatic Property Cluster kinds. Instead, Wilkins and Ebach define the naturalness of classification as the falling into hierarchical patterns, aligning the search for natural arrangement with the aim of systematics, and as something that is grounded in a cognitive task or activity. However, they leave the question of realism v. antirealism open. ‘‘In natural classification...we must have real relations no matter how we might interpret ‘real’’’ (p. 70). There is tension with regard to their ontological commitments as they vacillate between constructive, operationalist, and realist approaches. Wilkins and Ebach initially define real as that which is causal and important (pp. 70–71), and later as that which ‘‘depends in no way upon a mind or observer’’ (p. 122). This makes their claim that there was ‘‘no real theory involved [in the pre-Darwinian classifications of Jussieu and Adanson]’’ (p. 64) difficult to interpret. Cont’d……. (shrink)

In this chapter, we argue that in order to understand the interdisciplinary and transdisciplinary dialectics in sustainability science, it is useful to see sustainability science as a kind of management science, and then to highlight the hard-soft distinction in systems thinking. First, we argue that the commonly made natural-social science dichotomy is relatively unimportant and unhelpful. We then outline the differences between soft and hard systems thinking as a more relevant and helpful distinction, mainly as a difference between perspectives (...) in systemic modeling toward models. We also illustrate that the distinction is methodologically useful to advance sustainability science by enabling us (i) to suggest novel ways of using existing theoretical, experimental, and computational resources of the sciences for renewable resource management, and (ii) to disentangle disciplinary disagreements in climate science.

Scientists cannot devise theories, construct models, propose explanations, make predictions, or even carry out observations, without first classifying their subject matter. The goal of scientific taxonomy is to come up with classification schemes that conform to nature's own. Another way of putting this is that science aims to devise categories that correspond to 'natural kinds.' The interest in ascertaining the real kinds of things in nature is as old as philosophy itself, but it takes on a different guise when (...) one adopts a naturalist stance in philosophy, that is when one looks closely at scientific practice and takes it as a guide for identifying natural kinds and investigating their general features. This Element surveys existing philosophical accounts of natural kinds, defends a naturalist alternative, and applies it to case studies in a diverse set of sciences.

This essay explores Kant’s concept of absolute space in the Metaphysical Foundations from the perspective of the development of the relationist interpretation of bodily interactions in the center-of-mass reference frame, a strategy that Huygens had originally pioneered and which Mach also endorsed. In contrast to the interpretations of Kant that stress a non-relationist, Newton-inspired orientation in his critical period work, it will be argued that the content and function of Kant’s utilization of this reference frame strategy places him much closer (...) to Huygens’ relationism than the absolute notions of space and motion favored by Newton and Euler.

This chapter is an examination of the way aporiai are employed in Aristotle’s scientific account of animal reproduction, and how they are resolved. I argue that – surprising as it may be, given what Aristotle says in Metaphysics B about the importance of going through aporiai – there seems to be nothing of much significance about his use of them, at least if we assume that genuine cases of aporiai are being tracked by use of aporia-language. I demonstrate this negative (...) thesis by systematically going through the examples. There seems to be no common purpose for which they are raised, they have no single type of structure, and they are not caused by any one sort of difficulty. (shrink)

“Nature” is one of the most challenging concepts in philosophy, and notoriously difficult to define. In ancient Greece, two strategies for coming to terms with nature were developed. On the one hand, nature was seen as a perfect geometrical order, analysable with the help of geometry and deductive reasoning. On the other hand, a more Dionysian view emerged, stressing nature’s unpredictability, capriciousness and fluidity. This view was exemplified by De Rerum Natura, a philosophical masterpiece in verse. In a philosophy course (...) for science students, participants use both approaches. They are asked to give a definition of nature, and subsequently to capture nature in a poem. Quite consistently, their poetry proves more convincing than their definitions. In this paper, an anthology of student poetry is presented and analysed. To what extent may verse-writing as a philosophical assignment enable science students to come to terms with their understanding of nature? (shrink)
