These comments center on the methodological stance that Howard and Maiocchi recommend to us when we are doing history of philosophy. If Howard and Maiocchi are right, both Duhem and Einstein developed closely related versions of conventionalism and realism, and in both of their philosophies the conventionalist and realist moments were mutually compatible. Duhem's holism and, arguably, Einstein's as well, denies the need for across-the-board literalism, and both of them had important reasons for denying that convergence was required (...) or even desirable for realism. Thus, for those who are caught up in the current disputes, serious consideration of the discrepancies between the standard current versions of realism and conventionalism and the positions that contextualist analyses reveal to have been advocated by Duhem and Einstein may uncover some of the tacit assumptions that impede the resolution or advancement of our disputes.

Pierre Duhem and Jacques Maritain, influenced by positivist philosophies of science that prevailed in the late nineteenth and early twentieth centuries, adopted markedly non-realist views about the mathematical theories of the modern physical sciences. The philosophies of science they developed were a hybrid of Thomism and positivism. This paper argues that the ideas of Duhem and Maritain about the relation of the mathematical theories of modern physics to physical reality are inadequate in light of the insights modern physics (...) has yielded about the physical world.

Duhem’s problem arises especially in scientific contexts where the tools and procedures of measurement and analysis are numerous and complex. Several philosophers of cognitive science have cited its manifestations in fMRI as grounds for skepticism regarding the epistemic value of neuroimaging. To address these Duhemian arguments for skepticism, I offer an alternative approach based on Deborah Mayo’s error-statistical account in which Duhem's problem is more fruitfully approached in terms of error probabilities. This is illustrated in examples such as (...) the use of probabilistic brain atlases, comparison of different preprocessing protocols with respect to their error characteristics, and statistical modeling of fMRI data. These examples demonstrate the ways in which we can better understand and formulate the general methodological problem and direct the way toward alternative approaches to neuroimaging in philosophy of cognitive science, in which we can be more balanced and productive in our scrutiny of the epistemic value of neuroimaging studies.

In the late 19th century great changes in theories of light and electricity were in direct conflict with certitude, the view that scientific knowledge is infallible. What is, then, the epistemic status of scientific theory? To resolve this issue Duhem and Poincaré proposed images of fallible knowledge, Instrumentalism and Conventionalism, respectively. Only in 1919–1922, after Einstein's relativity was published, he offered arguments to support Fallibilism, the view that certainty cannot be achieved in science. Though Einstein did not consider (...) class='Hi'>Duhem's Instrumentalism, he argued against Poincaré's Conventionalism. Hitherto, Einstein's Fallibilism, as presented at first in a rarely known essay of 1919, was left in the dark. Recently, Howard obscured its meaning. Einstein's essay was never translated into English. In my paper I provide its translation and attempt to shed light on Einstein's view and its context; I also direct attention to Einstein's images of philosophical opportunism in scientific practice.

With the publication of this volume from the prolific pen of one of Germany's outstanding younger philosophers, the German-speaking scholarly world has a more extensive survey of key issues in the philosophy of science than the English-speaking world. The book is the first of a comprehensive work whose title is "Problems and Results in the Philosophy of Science and Analytic Philosophy." While the title of the book under consideration shows that it is primarily concerned with scientific explanation and justification, Stegmüller (...) not merely undertakes to acquaint his readers with the most important Anglo-American developments concerning these topics, but also independently develops his own ideas with respect to them and an important, if brief, feature of the volume is an appendix in which he sets forth over thirty "problems that are either unsolved or the solution of which is controversial." Without going into substantival detail, perhaps the quickest way to indicate Stegmüller's main concerns and general orientation is to note the extent of the page references in the index of names where, in descending order, one finds the names of Carl G. Hempel, to whom the volume is dedicated, R. Carnap, N. Goodman, N. Rescher, W. V. Quine, P. Oppenheim, E. Nagel, W. Dray and K. Popper. Curiously, Stegmüller indicates that, aside from Hempel, the man who has exercised the greatest influence on him has been Sir Karl Popper, but then he limits his consideration of him mainly to Popper's early exposition of explanation by reference to the breaking of a thread, while ignoring what he has to say about such topics as falsification, induction, and the problem of demarcation. Under these circumstances it is not surprising that there are no references to P. Duhem, J. Agassi, and P. Feyerabend, but there are also none to G. Bergmann, M. Bunge, P. Frank, N. R. Hanson, A. Koyré, V. Kraft, G. Radnitzky, and J. J. C. Smart, to mention just a few.--R. F. M. (shrink)

After a chapter which is an introduction to and summary of the rest of the book, chapter 2 begins by criticizing various attempts to do away with theories, such as the Reichenbach-Salmon conception of theoretical truth in terms of observational consequences, and the Ramsey strategy of replacing first-order theoretical sentences by second-order nontheoretical ones; it then argues against hypothetico-deductivist theories of confirmation on the grounds that they are unable to handle the relevance of evidence to theory, whether or not other (...) formal constraints or even nonformal ones such as simplicity and explanatory power are added to those theories; it ends with an exposition of the Reichenbach-Carnap conventionalist thesis that the confirmation of hypotheses with evidence presupposes analytic principles connecting hypothetical and empirical concepts. Chapter 3 criticizes Bayesian theories of confirmation on such grounds as that the a priori arguments for Bayesian restrictions on beliefs are insufficient; that the Bayesian explanations of notions like variety of evidence, ad hocness, and simplicity are inadequate; and that they cannot account, without drastic revisions, for the relevance of evidence to theory, especially old evidence to new theory. Chapter 4 is an unsympathetic account of historically oriented philosophies of science; Lakatos’s notion of progressive research programs and Laudan’s theory of problem-solving effectiveness are found to be insufficiently precise and dubbed examples of "new fuzziness", while the Sneed-Stegmüller dynamics of theories is regarded as "a paradigm of misplaced rigor" ; and all three are criticized as unable to explicate the concept of evidential relevance. Chapter 5 is a formal and informal elaboration of the basic idea in Glymour’s account of theory and evidence, namely that confirmation or support is a three-term relation among evidence, hypothesis, and theory, so that evidence confirms an hypothesis only relative to a theory, and such that evidence e confirms hypothesis h relative to T if T with e implies, but T without e does not imply, an instance of h, and T with e does not imply a comparable hypothesis h’ different from h; the most interesting part of this chapter is a series of discussions showing how such an idea makes sense of the "methodological truisms" that it is possible selectively to test certain parts of a theory but not others, that a theory is supported better by a greater variety of evidence, that redundant or physically meaningless quantities are an undesirable feature of theories, that there are no inviolable rules, that a "white shoe" does not confirm "all ravens are black," that a theory is more useful and better supported than the set of its observational consequences, and that the hypothetico-deductive method often works. Since Glymour claims no originality for the conception of this general account, but only for its description, he plausibly thinks it necessary to apply it to some important historical cases of actual science; he does so in the next chapter by discussing at some length the structure and merits of Ptolemaic and Copernican astronomy, of Newton’s universal gravitation, of nineteenth century atomism, of Freud’s Rat Man, and of general relativity. For example, he argues convincingly that Copernicanism was better supported by the evidence available even before the telescope because it alone, and not the Ptolemaic theory, can determine some planetary properties which are presupposed by both theories, can test and confirm some common hypotheses, and can be confirmed in an essential rather than incidental manner; and though Glymour admits that the Copernicans tended to argue in terms of explanatory rather than confirmatory superiority, he sketches an interesting account of the relation between explanation and confirmation which strengthens his case. He also analyzes the text at the beginning of book 3 of Newton’s Principia and compiles a reconstruction of the intricate details of the inferential structure of the argument to universal gravitation; his impressive reconstruction clearly shows that Newton’s method is neither the inductivist one he himself thought he was following, nor the one attributed to him by Pierre Duhem, but rather one in accordance with Glymour’s so-called "bootstrap strategy" of repeatedly using the evidence from Kepler’s second and third laws, from lunar data, and from falling bodies, together with the theory consisting of the second and third laws of motion, to arrive at increasingly general instances of the principle of universal gravitation. Glymour’s account of arguments for and against the atomic theory from Thomson to Cannizzaro is his longest historical example, but he himself admits that this illustration of the bootstrap strategy is "certainly not the neatest", and rather "diffuse, and perhaps disconnected". Chapter 7 is a detailed application of the same principles to the technique known among social scientists as "causal modeling"; since such "causal models" are essentially systems of algebraic equations, Glymour’s account shows indirectly that the bootstrap strategy is applicable to any scientific theory presented as a set of algebraic equations; this, of course is not surprising, since the formal considerations with which Glymour begins the exposition of his theory in chapter 5 involve systems of algebraic equations. Chapter 8 is an attempt to apply Glymour’s theory of evidence to the very common scientific practice of curve-fitting, where one measures values of two or more quantities and then infers a functional relationship; Glymour argues that simpler polynomials are preferred because they are tested more frequently and more severely by the data and because they are more informative; but then he criticizes his own explanation and concludes that "the bootstrap procedures of chapter 5 do not seem to help the problem much more than a whit" ; this is admirably honest, but if one wants an additional logical or methodological rationale, then one would perhaps have to go to the meta-level and say that Glymour is here testing his own theory, and he is more interested in a further illustration of the bootstrap methodology even with a failed test, than he is to claim universal or exclusive validity for it. In chapter 9 Glymour uses his bootstrap theory of confirmation to criticize geometrical conventionalism; he considers the alternative theories of space or space-time proposed by conventionalists to show the radical undetermination of geometries by evidence, for example, a non-Euclidean geometry with no universal force instead of Newtonian gravitation with Euclidean geometry; he argues that such alternatives are simply not as well tested as the originals and that their equivalence to the originals is questionable. The last chapter is a brief discussion of further problems worthy of future investigation. (shrink)

In concluding section 2, chapter VI of part II of [6], Duhem claimed:... the physicist can never subject an isolated hypothesis to experimental test, but only a whole group of hypotheses...... when the experiment is in disagreement with his predictions, what he learns is that at least one of the hypotheses constituting this group is unacceptable and ought to be modified; but the experiment does not designate which one should be changed'.

What were the true reasons of the second scientific revolution? – To answer the question, the epistemic model is applied, according to which radical breakthroughs in science were not due to the fanciful excogitation of new ideas ‘ex nihilo’, but rather to the tedious, long-term and troublesome processes of the mutual lapping, reconciliation, interpenetration and intertwinement of ‘old’ research traditions preceding such breaks. It is contended that Einstein's 'annus mirabilis' constituted an acme of the second scientific revolution. To fathom in (...) what felicitous ways Einstein's 1905 writings hang together one is bound to pay special tribute to his longed strive for unity evinced in incessant attempts to coordinate the profound research traditions of classical physics. Though Einstein's efforts sprung out of Max Planck's pioneering attempts to comprehend electromagnetic phenomena through the lenses of conceptual structures of statistical thermodynamics . It was Planck, who clearly realized the cross-contradiction between 'the physics of material bodies’ and ‘the physics of the ether' and outlined the sketch of its withdrawal: the paradigms 'must be modified to remain compatible'. And it was Planck who took the first step in modifying the physics of the ether and contending that 'not only matter itself but also the effects radiated from matter' possess discontinuous properties, which can be characterized by a new natural constant: the elementary quantum of action. Einstein's part consisted in that he took the second step in modifying the second component of the encounter – the physics of material bodies. Einstein’s foolhardy light quanta hypothesis and distinctive special theory of relativity turn out to be mere milestones of the unwinding of Maxwellian electrodynamics and statistical thermodynamics reconcilement research program. The notorious conception of luminiferous ether was a substantial obstacle for Einstein’s wayward statistical thermodynamics in which the pivotal lead was played by flagrant light quanta paper. Einstein was aware that his enticing light quanta hypothesis was too audacious to be taken literally and he laid out his version of 'electrodynamics of moving bodies' in a markedly Machian/ Duhemian, phenomenological way. As a result of the revision of the second scientific revolution key episode, the arguments are exhibited in favor of the necessity to modify the history of the genesis of general relativity; correspondingly, the process of unification of electromagnetic and weak interactions that took place in the second half of the XX-th century is scrutinized. Eventually, the encounter and interpenetration of the two dominating research traditions of modern physics – that of general relativity and quantum field theory – is elicited. (shrink)

Nugayev critically analyzes current conceptions of scientific change. Then he constructs his own normative model and compares it with actual problematic situations. In particular, he analyzes critically the replacement of Lorentz’s theory with the special theory of relativity. Key words: Popper, Duhem, Schlesinger, Lakatos, Kuhn .

In this book, Nugayev makes a clear case against Kuhnian and Lakatosian models. For him the origin of scientific revolutions lies in the clash of theories which are already mature and have triumphed in their respective spheres of action.

Duhem is perhaps the last active scientist to have produced a philosophi- cal text, and TheAim and Structure of Physical Theory retains its status as one that every textbook writer in the philosophy of science has to take into consideration. Several of Duhem’s other books have since appeared in English translation, but the Essays in the History and Philosophy of Science is the first collection of Duhem’s papers to appear in English. Commentators have oRen pointed out that (...) the roots of Duhem’s main philosophical work are to be found in a series of articles he wrote in the Catholic journal, Revue des Questions Scientijiques, during the first part of the 1890s, and it is not before time that these should be made available in English. In fact, the editors of the Essays have done us the greater ser- vice of including some of these seminal papers in a broader selection from Duhem’s shorter pieces, ranging over the years from 1892 to 1915 and covering his interests in the history of science and the relation between science and religion, as well as the philosophy of science. In the latter cat- egory, there is a nice little essay, “The Nature of Mathematical Reason- ing” from 1912, in which he takes issue with Poincark’s views on math- ematical induction, a review of Mach’s The Science of Mechanics (1903) and “Logical Examination of Physical Theory” - the section dealing with his philosophy of science from the submission he wrote in 1913 in sup- port of his membership of the Academie des Sciences. Like the latter, the last two chapters of To Save the Phenomena (1908) and “Some Reflec- tions on German Science” (1915) have already appeared in English. Of the remaining nine essays, eight appear, as far as I’m aware, for the first time here in English, while the “lightly edited” “History of Physics” origi- nally appeared in English. (shrink)

According to some currents of modern historiography, Galilei's propensity for circular motion would have led him to consider this and not rectilinear motion as “natural motion”; therefore the principle of inertia could not be fully attributed to Galileo, which he would never have formulated.

Die Frage: sind empirische Theorien falsifizierbar? ist natürlich trivialerweise zu verneinen, falls man Theorien nicht als Mengen von Aussagen, sonden z. B., wie Sneed/Stegmüller, als mengentheoretische Strukturen plus intendierte Anwendungsbereiche auffaßt. Daß die Antwort, zumindest dann, wenn man die Fragestellung auf bestimmte physikalische Theorien einschränkt, auch bei Zugrundelegung der sogenannten Aussagen-Konzeption (statement view) nicht anders lautet, ist hingegen schon weniger trivial — obgleich seit langem bekannt, spätestens nämlich seit Duhems berühmter Argumentation gegen die Möglichkeit eines experimentum crucis. Andererseits beruht eine (...) der derzeit einflußreichsten methodologischen Theorien, die von Popper, gerade auf der gegenteiligen Behauptung. Erst jüngst noch hat Popper seine Falsifizierbarkeits-Annahme, vor allem gegen Kritiken von Lakatos und Putnam, zu verteidigen versucht; die gleiche Intention verfolgen auch zwei Aufsätze von Musgrave. Es erscheint mir daher angebracht, kurz auf das Problem der Falsifizierbarkeit von empirischen Theorien zurückzukommen.Vorweg noch zwei Bemerkungen zur Terminologie: 1) Ich verwende, ohne mich auf den Versuch einer genaueren Explikation einzulassen, den Begriff (physikalische) Theorie in dem für den statement view geläufigen Sinne, wonach eine (deterministische) Theorie aus einer Menge von allgemeinen (deterministischen Natur-)Gesetzen besteht. Es sei ausdrücklich darauf hingewiesen, daß dies wenigstens partiell dem sonst üblichen Sprachgebrauch zuwider läuft: die Theorie des Planetensystems und die Mondtheorie, beispielsweise, sind keine Theorien im genannten Sinne, weil sie außer auf allgemeinen Naturgesetzen noch auf spezifischen nicht-gesetzesartigen Annahmen beruhen. Andrerseits dürfte diese Deutung des Begriffs Theorie zumindest mit derjenigen von Popper übereinstimmen. — 2) Daß eine Aussage bzw. Aussagenmenge T falsifizierbar ist, soll, wie bei Popper, bedeuten, daß Basissätze (wahre oder falsche) existieren, die zusammen mit T eine inkonsistente Satzmenge bilden; m.a.W.: falsifizierbar ist T in the simple logical sense of being logically incompatible with some basic statements. It has potential falsifiers. Basissätze sind dabei, grob gesagt, als Darstellungen von Beobachtungs-Befunden aufzufassen; Genaueres interessiert hier nur insoweit, als es sich umraum-zeitlich singuläre (Existenz-) Sätze handeln muß. Entsprechend soll schließlich T als falsifiziert gelten, wenn es wahre bzw. anerkannte oder akzeptierte Basissätze gibt, die T widersprechen. (Poppers Forderung, daß diese Basissätze ein reproduzierbares Phänomen beschreiben, also eine — allgemeine — falsifizierende Hypothese bewähren müssen, kann im vorliegenden Zusammenhang außer Betracht bleiben).

Pierre Duhem and Eugenio Randi have investigated the later-medieval history of the problem of whether the existence of more than one world is possible, determining that Aristotle's denial of that possibility was rejected on theological grounds in the second half of the thirteenth century, but it was Nicole Oresme in the mid-fourteenth century who gave the strongest philosophical arguments against the Peripatetic stance, opting instead for Plato's position.

Is it possible to establish a line of research that brings Gabriel Marcel and Jean-Paul Sartre closer together? With this article, we will positively support this idea, by distancing ourselves from the overly rigid interpretations that exclusively focus on antinomic elements sliding into a reductionist and nowadays “canonical” presentation of the relationship between these philosophers. Beyond the undeniable and, fortunately, unmediated differences between the two philosophers, this article aims to investigate their positions regarding the concept of “relationship”. In doing so, (...) we will highlight how Gabriel Marcel’s “coesse” and Jean-Paul Sartre’s “being-for-others” have numerous points of contact that place both philosophers, beyond their personal positions in the religious sphere, within the common ground of “existentialism”.

Reference is a central topic in philosophy of language, and has been the main focus of discussion about how language relates to the world. R. M. Sainsbury sets out a new approach to the concept, which promises to bring to an end some long-standing debates in semantic theory.There is a single category of referring expressions, all of which deserve essentially the same kind of semantic treatment. Included in this category are both singular and plural referring expressions, complex and non-complex referring (...) expressions, and empty and non-empty referring expressions. Referring expressions are to be described semantically by a reference condition, rather than by being associated with a referent. In arguing for these theses, Sainsbury's book promises to end the fruitless oscillation between Millian and descriptivist views. Millian views insist that every name has a referent, and find it hard to give a good account of names which appear not to have referents, or at least are not known to do so, like ones introduced through error, ones where it is disputed whether they have a bearer and ones used in fiction. Descriptivist theories require that each name be associated with some body of information. These theories fly in the face of the fact names are useful precisely because there is often no overlap of information among speakers and hearers. The alternative position for which the book argues is firmly non-descriptivist, though it also does not require a referent. A much broader view can be taken of which expressions are referring expressions: not just names and pronouns used demonstratively, but also some complex expressions and some anaphoric uses of pronouns.Sainsbury's approach brings reference into line with truth: no one would think that a semantic theory should associate a sentence with a truth value, but it is commonly held that a semantic theory should associate a sentence with a truth condition, a condition which an arbitrary state of the world would have to satisfy in order to make the sentence true. The right analogy is that a semantic theory should associate a referring expression with a reference condition, a condition which an arbitrary object would have to satisfy in order to be the expression's referent.Lucid and accessible, and written with a minimum of technicality, Sainsbury's book also includes a useful historical survey. It will be of interest to those working in logic, mind, and metaphysics as well as essential reading for philosophers of language. (shrink)

This book presents state of the art philosophical work on conspiracy theory research that brings in sharp focus on central and important insights concerning the supposed irrationality of conspiracy theory and conspiracy theory belief, while also proposing several novel solutions to long standing issues in the broader academic debate on these things called ‘conspiracy theories’. -/- It features a critical history of conspiracy theory theory, emphasising the role of the ‘first generation’ of philosophers in conspiracy theory research. This book also (...) includes discussions of a range of key issues such as: -/- What counts as conspiracy theory? Who counts as a conspiracy theorist? How are these terms variously understood by academics and the wider public, and Are conspiracy theories automatically suspect, and is it ever reasonable to be a conspiracy theorist? The book then builds upon that work by looking at how people’s political views affect both the conspiracy theories they believe and their beliefs about conspiracy theories; how we might defend conspiracy theorising without endorsing mad, bad or dangerous conspiracy theories; and contains several proposals for unifying conspiracy theory research under one theoretical framework: particularism. -/- This volume will be a key resource for philosophers and social scientists interested in recent work on the philosophy of conspiracy theory theory and its implications for conspiracy theory research. It will also appeal to members of the public, who want to know what, if anything, is wrong with these things called “conspiracy theories”.

This book analyzes for the first time in English the ethical theory that underpins Qur’anic legislation by providing a classification of specific verses in which Islam’s holy book discusses moral issues. The principal purpose of this book is to demonstrate the ways in which the Qur’an theoretically and practically provides the moral code to which Muslims around the world adhere. The author divides his analysis into a survey of Qur’anic attitudes towards the basic ethical issues of obligation and responsibility, issues (...) of moral psychology such as motivation and intention, as well as matters of social ethics such as the function of law in society. He then explores the meanings of individual morality, morality within the family and civil society, and the relationship of morality to the idea of the state. (shrink)
