This is an unedited version of a paper written in 2012 accepted for publication in a forthcoming Festschrift for Mark Platts. In it I argue that the Helmholtz/Bayes tradition of free energy neuroscience begun by Geoffrey Hinton and his colleagues, and now being carried forward by Karl Friston and his, can be seen as a fulfilment of the Quine/Davidson program of radical interpretation, and also of Quine’s conception of a naturalized epistemology. -/- This program, in turn, is rooted in Helmholtz’s (...) scientific reconception of Kant’s notion of a concept-led synthesis of affectations by an extra-sensory reality that creates human self-consciousness, a topic previously discussed in my (2012) Psychoanalysis, Representation, and Neuroscience. -/- I also argue that 20th century analytical philosophy went astray when Frege, Russell, and Wittgenstein ignored their legacy from Helmholtz and espoused a conception of perception and epistemology that he had already shown to be false.

Logic diagrams have been increasingly studied and applied for a few decades, not only in logic, but also in many other fields of science. The history of logic diagrams is an important subject, as many current systems and applications of logic diagrams are based on historical predecessors. While traditional histories of logic diagrams cite pioneers such as Leibniz, Euler, Venn, and Peirce, it is not widely known that Kant and the early Kantians in Germany and England played a crucial role (...) in popularising Euler(-type) diagrams. In this paper, the role of the Kantians in the late eighteenth and early nineteenth centuries will be analysed in more detail. It shows that diagrams (or intuition in general) were a highly contentious topic that depend on the philosophical attitude and went beyond logic to touch on issues of physics, metaphysics, linguistics and, above all, mathematics.

Inductive thinking is a universal human habit; we generalise from our experiences the best we can. The induction problem is to identify which observed regularities provide reasonable justification for inductive conclusions. In the natural sciences, we can often use strict laws in making successful inferences about unobserved states of affairs. In the social sciences, by contrast, we have no strict laws, only regularities which most often are conditioned on ceteris paribus clauses. This makes it much more difficult to make reliable (...) inferences in the social sciences. In particular, we want knowledge about general causal relations in order to be able to determine what to do in order to achieve a certain state of affairs. Knowledge about causal relations that are also valid in the future requires experiments or so called ‘natural experiments’. Only knowledge derived from such experiences enable us to draw reasonably reliable inferences about how to act in order to achieve our goals. (shrink)

The scientific community takes for granted a view of science that may be called standard empiricism. This holds that the basic intellectual aim of science is truth, nothing being presupposed about the truth, the basic method being to assess theories with respect to evidence. A basic tenet of the view is that science must not accept any thesis about the world as a part of scientific knowledge independent of evidence, let alone in violation of evidence. But physics only accepts unified (...) theories, and persistently rejects infinitely many ad hoc rivals that fit the phenomena even better. In persistently rejecting these infinitely many empirically more successful rival theories, physics thereby makes a substantial assumption about the universe – it is such that all ad hoc theories are false – an assumption that is accepted implicitly independently of evidence, even in a sense against the evidence. That contradicts standard empiricism. The scientific community needs to adopt a new conception of science that represents the assumption of physics as a hierarchy of assumptions, thus facilitating the improvement of the assumption that is made, as science proceeds.

In this collection of essays, philosopher Paul Russell addresses major figures and central topics of the history of early modern philosophy. Most of these essays are studies on the philosophy of David Hume, one of the great figures in the history of philosophy. One central theme, connecting many of the essays, concerns Hume's fundamental irreligious intentions. Russell argues that a proper appreciation of the significance of Hume's irreligious concerns, which runs through his whole philosophy, serves to discredit the deeply entrenched (...) framework for understanding Hume - and much of early modern philosophy - in terms of the idea of "British Empiricism". In a substantive introduction, Russell outlines how his various insights overlap and connect to each other. -/- The volume is organized thematically into five sections: metaphysics, free will, ethics, religion, and general interpretations of Hume's philosophy. The collection also features a previously unpublished essay on Hume's atheism and an essay on Adam Smith's views on religion and ethics that has not been previously published in English. -/- Recasting Hume and Early Modern Philosophy presents the reader with Russell's substantial and significant set of interconnected observations and insights on the matters and figures of the greatest importance in early modern philosophy. These essays not only provide different and original perspectives on the subject, they also show that the various issues addressed are very relevant to each other, as well as to a number of major topics in contemporary philosophy.

This paper pulls together three debates fundamental in metaphysics and proposes a novel unified approach to them. The three debates are (i) between bundle theory and substrate theory about the nature of objects, (ii) dispositionalism and categoricalism about the nature of properties, and (iii) regularity theory and production theory about the nature of causation. The first part of the paper (§§2-4) suggests that although these debates are metaphysical, the considerations motivating the competing approaches in each debate tend to be epistemological. (...) The second part (§§5-6) argues that the two underlying epistemological pictures supporting competing views lead to highly unsatisfying conceptions of the world. The final part (§§7-10) proposes an alternative epistemological picture, which I call ‘introverted empiricism,’ and presents the way it provides for a more satisfying grasp of the ultimate nature of objects, properties, and causation. It is a consequence of this alternative picture that there is a kind of intimate self-understanding that underlies our understanding of the deep nature of reality. (shrink)

This paper is a defense of the evidentiality of epistemic intuitions. To that end, I will first briefly discuss both experimentalists’ and some salient forms of reliabilists’ accounts of intuition, showing that they bring us up to a stalemate. To find a way out of this standoff, I will argue that reliabilists’ accounts pave the way for experimentalists’ challenge to the epistemic value of intuitions in two ways. First, each of reliabilists’ accounts leaves enough space to be occupied by normativity. (...) Second, their foundationalism being established on an intuition-perception analogy also does so. Subsequently, I will argue that reliabilists’ line of argument overlooked what I call as the metaphysical necessity of epistemic intuitions. Keeping in mind this necessity, I say, allows us to eliminate the standoff and to draw the boundaries between two distinct kinds of intuition which, I will conclude, should be isolated but also fit together in a unified and inclusive model. -/- .

"I tend to agree with more dialectical positions such as Noxon's who, even being a critic of the approach of the two concepts, writes the following: Hume explained certain mental phenomena, notably belief, as effects of the association. And, going further, I say that belief is a feeling or sensation aroused by two factors: habit and the association of ideas, but it does not arise either from one or from other singly, each one is a part of a process that (...) involves both. Therefore habit is an underlying principle which acts upon reasonable beings during their observation of constant conjunctions, in such a way that imagination can associate ideas only through this principle acting in the mind. However, as I have already stated in another text, such an association realised by the imagination will catch up to its certainty status just with the emergence of a feeling which imputes necessity to what is instead merely contingent" (Sample taken up from the text).

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Recent work on skin-brain thesis suggests the possibility of empirical evidence that empiricism is false. It implies that early animals need no traditional sensory receptors to be engaged in cognitive activity. The neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of the (...) animal body. In other words, the nervous system first evolved for action, not for receiving sensory input. Thus, sensory input is not required for minimal cognition; only action is. The whole body of an organism, in particular its highly specific animal sensorimotor organization, reflects the bodily and environmental spatiotemporal structure. The skin-brain thesis suggests that, in contrast to empiricist claims that cognition is constituted by sensory systems, cognition may be also constituted by action-oriented feedback mechanisms. Instead of positing the reflex arc as the elementary building block of nervous systems, it proposes that endogenous motor activity is crucial for cognitive processes. In the paper, I discuss the issue whether the skin-brain thesis and its supporting evidence can be really used to overthrow the main tenet of empiricism empirically, by pointing out to cognizing agents that fail to have any sensory apparatus.

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, his proposed (...) solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

I give a brief overview of Albert Casullo’s Essays on A Priori Knowledge and Justification, followed by a summary of his diagnostic framework for evaluating accounts of a priori knowledge and a priori justification. I then discuss Casullo’s strategy for countering deficiency arguments against empiricism. A deficiency argument against empiricism can be countered by mounting a parallel argument against moderate rationalism that shows moderate rationalism to be defective in a similar way. I argue that a particular deficiency argument put forth (...) by George Bealer in “The Incoherence of Empiricism” can withstand a parallel challenge mounted by Casullo.I then consider Casullo’s preferred analysis of the concept of a priori justification, which identifies a belief’s being justified by some nonexperiential source as the feature by virtue of which it is justified a priori. On the analysis, an apriori-justfied belief that is justified to a degree that is sufficient for knowledge is not taken to be empirically indefeasible. I argue that Casullo could avail himself of an empirical indefeasibility requirement that is consistent with his minimal and fallibilist conception of a priori knowledge. Doing so would capture a feature of the concept of a priori knowledge that is of particular interest and significance. (shrink)

The concept of observability is of key importance for a consistent defense of Constructive Empiricism. This anti-realist position, originally presented in 1980 by Bas van Fraassen in his book The Scientific Image, crucially depends on the observable/unobservable dichotomy. Nevertheless, the question of what it means to observe has been faced in an unsatisfactory and inadequate manner by van Fraassen and this represents an important lacuna in his philosophical position. The aim of this work is to propose a characterization of the (...) act of observation able to give the necessary support to the ‘rough guide’ of ‘observable’ that can be found in the aforementioned book. Countering van Fraassen’s own statements, that observability is not a matter for philosophy, but for scientific inquiry only, we maintain that any attempt to deal with this subject by the philosophers is legitimate. We will show that van Fraassen ended up doing a philosophical analysis of observation himself, albeit in a fragmentary way. We believe that this question should be dealt with methodically, though, ‘following the rules’ of a ‘proper’ philosophical analysis, as we attempted to do in this work. We will propose a way of conceiving the act of observation, different from van Fraassen’s one, that can help not only to ground the distinction between observable and unobservable, upon which Constructive Empiricism rests, but to get this anti-realist position closer to scientific practice as well, which is one of its desiderata. Without neglecting the philosophical dimension of the issue, though. However, this proposal does not represent an ad hoc ‘solution’ for Constructive Empiricism, but a characterization aspiring to have a universal reach. (shrink)

For four decades it has been argued that we need to adopt a new conception of science called aim-oriented empiricism. This has far-reaching implications and repercussions for science, the philosophy of science, academic inquiry in general, conception of rationality, and how we go about attempting to make progress towards as good a world as possible. Despite these far-reaching repercussions, aim-oriented empiricism has so far received scant attention from philosophers of science. Here, sixteen objections to the validity of the argument for (...) aim-oriented empiricism are subjected to critical scrutiny. (shrink)

Sgarbi just shows that in the century before Locke’s Essay Concerning Human Understanding many writers mentioned induction and many claimed that knowledge must rely somehow on sense experience. An attempt to revive Randall’s thesis needs more than that.

In his Empirical Stance, van Fraassen introduces a new version of empiricism and elaborates its relation with science and religion. van Fraassen's empirical stance, characterized by a negative attitude towards metaphysics, is to result in a coherent view alongside his new epistemology called voluntarism - a non-dogmatic approach to rationality. This paper aims to show that its coherency is unstable. Because traces of dogmatism still plague van Fraassen's account of empiricism, and attempts to eliminate them lead to critical rationalism, affecting (...) his encounter with metaphysics. In the end, while stating some cases from the history of science, it will be emphasized that empiricism should not tie its identity with the opposition to metaphysics. (shrink)

Then I tentatively explore an option I find in Quine's own philosophy which can eventually avoid the issues raised by that problem. The price to pay in following this option, though, is a certain reinterpretation of the empiricist spirit of Quine's philosophy.

O preço de seguir o caminho indicado por esse resquício é, contudo, certa interpretação do espírito empirista da filosofia de Quine. (shrink)

Nach einer kurzen Übersicht über das Leben und Werk von Helmholtz, diskutiere ich die drei Themenbereiche, die für die Beurteilung seines Verhältnisses zu Kant vornehmlich ins Gewicht fallen. Der erste Bereich bildet die Begründung des Energieerhaltungssatzes von 1847, den der späte Helmholtz selbst „durch Kant’s erkenntnistheoretische Ansichten […] beeinflusst“ gesehen hat. Während viele Interpreten diese Selbstauskunft für berechtigt halten, sehe ich in der Struktur der Begründung einen Ausdruck der gegensätzlichen Wissenschaftsauffassungen von Helmholtz und Kant. Als zweites gehe ich auf die (...) Rolle der Kausalität in der Wahrnehmungstheorie ein. In diesem Kontext bezieht sich Helmholtz erstmals und durchaus positiv explizit auf Kant. Seine Rede "Über das Sehen des Menschen" von 1855 zur Einweihung eines Kantdenkmals in Königsberg gilt als eines der Gründungsdokumente des Neukantianismus und spiegelt doch zugleich die tiefgreifenden Differenzen zwischen empiristischer und idealistischer Wissenschaftsphilosophie wider. Zeitlich wiederum nachfolgend steht die Begründung der nichteuklidischen Geometrien als dritter Bereich für die deutlichste Kritik an Kants transzendentaler Begründung der Wissenschaft.

Zeitlich wiederum nachfolgend steht die Begründung der nichteuklidischen Geometrien als dritter Bereich für die deutlichste Kritik an Kants transzendentaler Begründung der Wissenschaft. Sie ist zugleich wohl auch Helmholtz’ bekanntester Beitrag zur Hypothetisierung der Wissenschaftssauffassung. Dem Werk von Hermann von Helmholtz wird gemeinhin ein maßgeblicher Stellenwert bei der Begründung der neukantianischen Bewegung im 19. Jahrhundert beigemessen. Wo diese Zuordnung Helmholtz’ positive Bezüge auf Immanuel Kant ohne hinreichende Kontextualisierung hervorhebt, läuft sie Gefahr, die Distanz zu übersehen, die zwischen den wissenschaftsphilosophischen Positionen von Helmholtz und Kant bestand. In meinem Beitrag gewinnt das Verhältnis von Helmholtz zu Kant erst seine Bedeutung vor dem Hintergrund ihrer konträren ontologischen und erkenntnistheoretischen Grundannahmen. Helmholtz betrachte ich als repräsentativen Vertreter einer szientistischen Wissenschaftsauffassung in der Naturforschung des 19. Jahrhunderts. Demgegenüber bietet Kant ein paradigmatisches Beispiel einer metaphysischen Wissenschaftsbegründung. Im Gegensatz zu Kant beschränkt Helmholtz seinen Ausgangspunkt nicht auf erfahrungsfreie Prinzipien, sondern entwickelt und stützt seine Begründung des Geltungsanspruches der wissenschaftlichen Erkenntnis auf forschungsbewährte Theorien und Experimente. Eine Differenz zwischen den beiden Positionen findet sich ebenfalls in den Strukturen der jeweils vertretenen Naturkonzeptionen. Führt Kants dynamischer Mechanismus alle Eigenschaften der Materie auf Kräfte zurück, so geht Helmholtz von einer Dualität von Kraft und Materie aus. (shrink)

A critical survey of Quine's arguments against the analytic/synthetic distinction.

A 2012 review article for Metascience which explains Mach's realistic brand of empiricism, contrasting it with the common phenomenalist reading of Mach by John Blackmore in two recent books.

George Gemistos Plethon’s work in all its dimensions has attracted many scholars across the ages. One of those scholars was Alexandre Joseph Hidulphe Vincent, a French mathematician and erudite, who in the first and the only critical edition of Plethon’s Book of Laws by C. Alexandre in the nineteenth century, added three notes on his calendar, metrics and music, as he could reconstruct them from the ancient text. Vincent’s calculations were dictated by the main scientific thought of his time, which (...) was Positivism, and through this he thus contributed to the elucidation of some practical aspects of Plethon’s metaphysics. The results of meticulous calculations of the Plethonian calendar, metrics and musical modes show that the scientific spirit, which started appearing in the last days of Byzantium and during the Renaissance, was not only a revival of Antiquity, but an innovative attempt at explaining and being in accordance with the social demands and the physical reality of the time, both being understood as an extension of the metaphysical order. Vincent’s positivistic approach allows considering the impact of Plethon’s system in a postmodern perspective. (shrink)

After summarizing the essential details of Anil Gupta’s account of perceptual justification in his book _Empiricism and Experience_, I argue for three claims: (1) Gupta’s proposal is closer to rationalism than advertised; (2) there is a major lacuna in Gupta’s account of how convergence in light of experience yields absolute entitlements to form beliefs; and (3) Gupta has not adequately explained how ordinary courses of experience can lead to convergence on a commonsense view of the world.

I sketch a philosophical program called ‘Empirical Fundamentalism,’ whose signature feature is the extensive use of a distinction between fundamental and derivative reality. Within the framework of Empirical Fundamentalism, derivative reality is treated as an abstraction from fundamental reality. I show how one can understand reduction and supervenience in terms of abstraction, and then I apply the introduced machinery to understand the relation between water and H2O, mental states and brain states, and so on. The conclusion is that such relations (...) can be understood either as metaphysical contingencies or as necessary type-identities. (shrink)

Conceptual analyses can be subdivided into two classes, good and evil. Em- pirical analysis is the good kind, routinely practiced in the sciences. Orthodox analysis is the malevolent version that plagues philosophical discourse. In this paper, I will clarify the difference between them, provide some reasons to prefer good over evil, and illustrate their consequences for the metaphysics of causation. By conducting an empirical analysis of causation rather than an orthodox analysis, one can segregate the genuine metaphysical problems that need (...) to be addressed from the many pseudo-problems that have long dogged traditional accounts of causation.

For over 30 years I have argued that we need to construe science as accepting a metaphysical proposition concerning the comprehensibility of the universe. In a recent paper, Fred Muller criticizes this argument, and its implication that Bas van Fraassen’s constructive empiricism is untenable. In the present paper I argue that Muller’s criticisms are not valid. The issue is of some importance, for my argument that science accepts a metaphysical proposition is the first step in a broader argument intended to (...) demonstrate that we need to bring about a revolution in science, and ultimately in academic inquiry as a whole so that the basic aim becomes wisdom and not just knowledge.

This is a review of Craig Dilworth's The Metaphysics of Science (Dordrecht, Springer, 2007). The book propounds an immensely important idea. Science makes metaphysical presuppositions. Unfortunately, Dilworth ignores work that has been done on this issue which takes the matter much further than he does.

Many see modern science as having serious defects, intellectual, social, moral. Few see this as having anything to do with the philosophy of science. I argue that many diverse ills of modern science are a consequence of the fact that the scientific community has long accepted, and sought to implement, a bad philosophy of science, which I call standard empiricism. This holds that the basic intellectual aim is truth, the basic method being impartial assessment of claims to knowledge with respect (...) to evidence. Standard empiricism is, however, untenable. Furthermore, the attempt to put it into scientific practice has many damaging consequences for science. The scientific community urgently needs to bring about a revolution in both the conception of science, and science itself. It needs to be acknowledged that the actual aims of science make metaphysical, value and political assumptions and are, as a result, deeply problematic. Science needs to try to improve its aims and methods as it proceeds. Standard empiricism needs to be rejected, and the more rigorous philosophy of science of aim-oriented empiricism needs to be adopted and explicitly implemented in scientific practice instead. The outcome would be the emergence of a new kind of science, of greater value in both intellectual and humanitarian terms. (shrink)

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.

Helmholtz initially ascribes more to theoretical knowledge than merely that it is a picture of the world: it penetrates even to the unobservable causes of the phenomena which he conceived throughout his career as matter set mechanically in motion. The introduction of the picture-concept in the 1860s to characterize scientific theories marks the beginning of the loss of a direct connection with the world. Theories now constitute only a representation of a law-like structure of the world but no longer shed (...) light on the objects themselves. Beginning in the late 1870s, this knowledge of laws takes on an increasingly hypothetical character. (shrink)

The production of scientific instruments in America was neither a postwar phenomenon nor dramatically different from that of several other developed countries. It did, however, undergo a step-change in direction, size and style during and after the war. The American scientific instrument industry after 1945 was intimately dependent on, and shaped by, prior American and European experience. This was true of the specific genres of instrument produced commercially; to links between industry and science; and, just as importantly, to manufacturing practices (...) and cultures. I will argue that, despite the new types of instrument commercialized after the war, this historical continuity of links with science and scientists guided and constrained the design and manufacture of these products. Nevertheless, new designers, manufacturers and customers gradually transformed the culture of scientific instruments in the second half of the century. -/- This chapter deals with a subset of the American instrument industry, namely the measuring and monitoring instruments manufactured for scientific use. Even with the specification of ‘scientific’ instruments, however, these borders are rather artificial and unclear: instrument making from the seventeenth through the twentieth century has generally involved the fabrication of both standard products and custom-made devices for scientific use.2 In this context of sales quantities, ‘scientific’ instruments have often been defined as low-volume, special-order or custom devices. In a similar vein, ‘scientific’ instruments were commonly distinguished from ‘production’ instruments by context of usage, namely their very absence from – and indeed irrelevance to – production environments. This demarcation according to customer and environment was mirrored in at least one furth er respect: the training of their users. The classification into ‘scientific’ and ‘engineering’ applications was as fluid as the relationship between American universities and technical industries themselves.Despite these complementary definitions, the notion of the ‘scientific instrument’ was beginning to prove inadequate even at the turn of the twentieth century, and dramatically so when discussing the post-Second World War period. Definitions altered qualitatively after the Second World War in at least three further ways: (a) new genres of device altered the scope of the scientific instrument; (b) the contribution of State and military sponsorship of new forms of instrument became significant; and, (c) the postwar demand for specialist instruments increased rapidly, owing to wartime innovation, new applications and new customers. I will explore the evolution of instrument manufacturing in this changing context of new technology, funding, development and markets. (shrink)

Two criteria are proposed for characterizing the diverse and not yet perspicous relations between nanotechnology und nature. They assume a concept or nature as that which is not made by human action. One of the criteria endorses a distinction between natural and artificial objects in nanotechnology: the other allows for a discussion of the potential nanotechnological modification of nature. Insofar as current trends may be taken as indicative of future development, nanotechnology might increasingly use the model of nature as a (...) point of orientation, while many of its products will continue to be clearly distinguished from nature.

This paper constitutes one extended argument, which touches on various topics of Critical Rationalism as it was initiated by Karl Popper and further developed in his aftermath. The result of the argument will be that critical rationalism either offers no solution to the problem of induction at all, or that it amounts, in the last resort, to a kind of Critical Rationalist Inductivism as it were, a version of what I call Good Old Induction. One may think of David Miller (...) as a contemporary representative of what I consider as the ‘no solution’ version of critical rationalism, while Alan Musgrave stands for the version of ‘critical rationalist induction’. Popper’s own writings admit of either interpretation. (shrink)

In this paper I argue for a priori conjectural scientific knowledge about the world. Physics persistently only accepts unified theories, even though endlessly many empirically more successful disunified rivals are always available. This persistent preference for unified theories, against empirical considerations, means that physics makes a substantial, persistent metaphysical assumption, to the effect that the universe has a (more or less) unified dynamic structure. In order to clarify what this assumption amounts to, I solve the problem of what it means (...) to say of a theory that it is unified. There are, I argue, eight different kinds of unity important in theoretical physics, all varieties of one basic idea. This provides us with a precise way of partially ordering physical theories with respect to their degree of unity. It also leads to a hierarchical view of physics, according to which physics makes a number of increasingly insubstantial metaphysical assumptions concerning the comprehensibility and knowability of the universe. Two of these are identified as constituting a priori conjectures. I conclude by arguing that the view developed in the paper resolves the traditional clash between empiricism and rationalism in the philosophy of science, and has important implications for science, and for academic inquiry more generally.

I would like to assume that Reichenbach's distinction of Justification and Discovery lives on, and to seek arguments in his texts that would justify their relevance in this field. The persuasive force of these arguments transcends the contingent circumstances apart from which their genesis and local transmission cannot be made understandable. I shall begin by characterizing the context distinction as employed by Reichenbach in "Experience and Prediction" to differentiate between epistemology and science (1). Following Thomas Nickles and Kevin T. Kelly, (...) one can distinguish two meanings of the context distinction in Reichenbach's work. One meaning, which is primarily to be found in the earlier writings, conceives of scientific discoveries as potential objects of epistemological justification. The other meaning, typical for the later writings, removes scientific discoveries from the possible domain of epistemology. The genesis of both meanings, which demonstrates the complexity of the relationships obtaining between epistemology and science, can be made understandable by appealing to the historical context (2). Both meanings present Reichenbach with the task of establishing the autonomy of epistemology through the justification of induction. Finally, I shall expound this justification and address some of its elements of rationality characterizing philosophy of science(3). (shrink)

The topic of this contribution is the tension between the everyday dichotomy of nature and technology and the nanotechnological understanding of the world. It is essential to nanotechnology that nature and technology not be categorically opposed as the manmade and the non-manmade, but rather regarded as parts of a structurally identical whole. After the introduction, I will address three points: In a brief first section I will formulate a few questions and a thesis about the nanotechnological developments that can be (...) expected to come. In the main section I will assess four aspects of everyday understanding of nature and technology that are used to legitimate nanotechnology. Finally I will discuss whether an everyday understanding of nature can be conceived as a critical authority with respect to the nanotechnology program. (shrink)

Die Darstellung konzentriert sich auf den Naturbegriff in seinem Verhältnis zu Kultur, die folglich nur reduzierte Charakterisierung erfährt. Herausgearbeitet werden vor allem die Umfänge, Eigenschaften und Grenzen der auf Kultur bezogenen Naturbegriffe. Das Feld dieser Bedeutungen ist in einer Pluralität von sich teils überschneidenden, teils wechselseitig ergänzenden Naturbegriffen eingebettet. Weil erst vor diesem Hintergrund die Spezifität der Beziehung von Natur und Kultur sowie ihrer Natur - Kultur und ihr Anderes Bestimmungselemente deutlich wird, beginne ich mit einer Vorbemerkung zum Naturdiskurs (1). (...) Im Anschluss daran stelle ich fünf Varianten der Verhältnisbestimmung von Natur und Kultur vor. Bei den ersten beiden handelt es sich um die klassischen Entgegensetzungen von Natur zu Technik einerseits und zu Geschichte andererseits. Die Differenz von Natur und Technik geht auf Aristoteles zurück und hat sich bis heute vor allem Aktualität im lebensweltlichen Erfahrungsbereich bewahrt. (2). Den lebensweltlichen Nahbereich des direkt Wahrnehm- und Veränderbaren transzendiert die exemplarisch von Jean-Jacques Rousseau formulierte Gegenüberstellung von Natur und Geschichte. (3). Übergangsbereiche von Natur und Kultur sowie Bereiche, in denen sich zwischen beiden nicht mehr sinnvoll unterscheiden lässt, sind in den vergangenen zwei Jahrhunderten zunehmend zum Gegenstand wissenschaftlicher Arbeit geworden. Die Vielfalt der gegenwärtigen Forschungen in diesem Zusammenhang gestattet keine einheitliche Bestimmung des Natur-Kultur-Verhältnisses. Es lassen sich jedoch gemeinsame Strukturen bevorzugter Thematisierungsrichtungen ausmachen. Dazu gehört das Festhalten an den beiden, nicht dualistisch aufgefassten Begriffen als Bezeichnung von Gegenstandskomponenten. Hieran anknüpfend schlage ich vor, die Begriffe als polare Extreme eines Feldes von Mischungszuständen zu verstehen (4). Abschließend folgen die zwei Varianten, in deren Konsequenz es liegt, die Legitimität jeweils eines der beiden Begriffe zu bestreiten: Die naturalistische und die kulturalistische Variante. Sie rekurrieren jeweils beide auf einen historischen Prozess und sind als theoretisches Programm formuliert (5 und 6). (shrink)

Quine, criticism of Quine's Naturalized Epistemology.

Ernst Waldfried Josef Wenzel Mach was born 18 February 1838 in the Moravian village of Chrlice (near Brno), at that time part of the Austrian Monarchy, now the Czech Republic, and died 19 February 1916 in Vaterstetten (near Munich). He enjoyed a very successful career as an experimental physicist (the unit for the velocity of sound has been named after him). His importance for the philosophy of science derives mainly from his “historico‐critical” writings (Mach 1872, 1883, 1896b, 1921). Mach studied (...) mathematics and physics at the University of Vienna (1855–60, doctorate in physics 1860, his “Habilitation” (i.e., qualification to become a university professor) 1861) and his subsequent work was in the physiology of the senses. In 1864 he became professor first of mathematics and then (1866) of physics at Graz University; from 1867 to 1895 he was professor of experimental physics at Prague University; and in 1895 he took a chair in “Philosophy, especially the History and Theory of the Inductive Sciences” at Vienna University. In 1898 a stroke ended Mach's university teaching, but he was able to continue scientific work to a certain degree. (shrink)

In searching for the origins of current conceptions of science in the history of physics, one encounters a remarkable phenomenon. A typical view today is that theoretical knowledge-claims have only relativized validity. Historically, however, this thesis was supported by proponents of a conception of nature that today is far from typical, a mechanistic conception within which natural phenomena were to be explained by the action of mechanically moved matter. Two of these proponents, Hermann von Helmholtz and his pupil Heinrich Hertz, (...) contributed significantly to the modernization of the conception of science. Paradigmatic for their common contribution to this development is the way in which they employed the concept of image. By considering the origin and the different meanings of this concept we may trace a line of development which begins with Helmholtz's original claim that a universally and forever valid theory provides a unique representation of nature. It continues with the realization that the status of scientific knowledge is capable of revision; and it arrives at Hertz's admission that a variety of theories over a domain of objects is possible, at least at times.

Mit seinem Einfluß auf die Entwicklung der Physiologie, Physik und Geometrie ist Hermann von Helmholtz wie kaum ein anderer Wissenschaftler der zweiten Hälfte des 19. Jahrhunderts repräsentativ für die Naturforschung in Deutschland. Nicht weniger repräsentativ nimmt sich die Entwicklung seiner Wissenschaftsauffassung aus. Während er bis in die späten 60er Jahre einen emphatischen Wahrheitsanspruch der Wissenschaft vertrat, begann er in der nachfolgenden Zeit, die Geltungsbedingungen der wissenschaftlichen Erkenntnis einer Relativierung zu unterwerfen, die zusammenfassend als Hypothetisierung bezeichnet werden kann. Helmholtz entwickelte damit (...) schon im vergangenen Jahrhundert Ansätze einer Wissenschaftsauffassung , die in erstaunlichem Umfang in die Richtung der Moderne weisen. Wie nah er späteren Wissenschaftsauffassungen bereits gekommen ist, kann ein Vergleich mit Karl R. Poppers Forschungslogik illustrieren. In seiner Forschungslogik ist die Hypothetisierung der wissenschaftlichen Erkenntnis entschieden weiter vorangeschritten als in Heimholtz' Wissenschaftstheorie. Was sich bei Helmholtz erst vage abzuzeichnen beginnt, ist bei ihm bereits explizit formuliertes Programm geworden. Obwohl HeImholtz und Popper in keiner direkten wissenschaftstheoretischen Entwicklungslinie stehen und Popper sich in seinen Schriften auch nur sehr selten und beiläufig auf Helmholtz bezieht, finden sich dennoch überraschende und bisher nicht beachtete Berührungspunkte, die insbesondere dann hervortreten, wenn man Heimholtz' Wissenschaftsauffassung vor dem Hintergrund von Poppers Forschungslogik betrachtet.

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.

With his influence on the development of physiology, physics and geometry, Hermann von Helmholtz – like few scientists of the second half of the 19th century – is representative of the research in natural science in Germany. The development of his understanding of science is not less representative. Until the late sixties, he emphatically claimed the truth of science; later on, he began to see the conditions for the validity of scientific knowledge in relative terms, and this can, in summary, (...) be referred to as hypothesizing. Already in the past century, HeImholtz made first approaches to an understanding of science, which were incompatible with his own former position and which pointed to the modern age to an astonishingly large extent. A comparison with Karl R. Popper's logic of research will illustrate how closely he nevertheless approached modern understanding of science. In Popper's logic of research, hypothesizing of scientific knowledge is definitely much more advanced than in Helmholtz's theory of science. What begins vaguely to emerge with Helmholtz has already become an explicitly formulated programme with Popper. Although HeImholtz and Popper are not on a direct line of epistemological development and Popper refers to HeImholtz only rarely and casually, there are in fact surprising points of contact which have not been taken notice of so far and which appear above all if one looks at Helmholtz's understanding of science against the background of Popper's logic of research.

Radical empiricism is the view that a person's experiences (sensory and introspective), or a person's observations, constitute the person's evidence. This view leads to epistemic self-defeat. There are three arguments, concerning respectively: (1) epistemic starting points; (2) epistemic norms; (3) terms of epistemic appraisal. The source of self-defeat is traced to the fact that empiricism does not count a priori intuition as evidence (where a priori intuition is not a form of belief but rather a form of seeming, specifically intellectual (...) as opposed to sensory). Moderate rationalism, by contrast, avoids self-defeat. (shrink)
