Le Père Ignace Carbonnelle, l'un des principaux fondateurs de la Société scientifique de Bruxelles en 1875 et son secrétaire général depuis cette époque, décède inopinément en 1889 après une quin­zaine d'années durant lesquelles il fut «l'homme fort» de ladite Société. Aussitôt, la Revue des questions scienti­fiques annonce la triste nouvelle, promettant, pour un prochain numéro, une étude détaillée de sa vie et de son œuvre. Elle ne paraîtra jamais, de sorte que sa mort ne fut pas saluée avec l'ampleur qu'on (...) était en droit d'attendre. Et pour cause ! Au ter­me d'une enquête digne d'un roman policier, cette étude révèle que Rome, agacée par l'atomisme de Carbonnelle, profita de sa mort pour rappeler à l'ordre la Société en l'invitant à marcher dans les pas de l'Aquinate. En réponse à cette pressante invi­tation et par un excès de zèle non requis, la Société élut comme président le célèbre thomiste français Edmond Domet de Vor­ges, cependant que le mathématicien Paul Mansion s'attacha d'établir, à partir des publications de Pierre Duhem prônant un retour à une physique des qualités, que la Société se conformait bien, mais à sa manière, aux injonctions romaines. ––– Fr. Ignace Carbonnelle, who founded the Brussels Scientific Society in 1875 and was from this date onwards her Secretary General, passed away suddenly in 1889, after fifteen years during which he was the leading figure of the aforementioned Society. “La Revue des Question scientifique” announced the sad news but promised that their next publication would include a detailed article on the great man and his works. Sadly this article never appeared, meaning that the passing of Fr. Carbonnelle was not marked with the importance which we might have otherwise expected. For what reason, you may well ask? After a detailed investigation, worthy of Agatha Christie herself, it would appear that Rome had been rather alarmed by the “atomism” present in Fr. Carbonnelle's reflections, and had taken the opportunity of his death to invite the Scientific Society to opinions more in line with those of St Thomas. In response to this firmly worded invitation, and with overzealous spontaneity, the Society elected the celebrated French Thomiste Edmond Domet de Vorges as their new President. At the same time the mathematician Paul Mansion relied on the publications of Pierre Duhem, which advocated a stronger adhesion to a physics of an object's qualities, to establish that the Society was, in fact, well aligned with the desires of Rome.

The holistic thesis developed by Pierre Duhem challenges the idea that our evidence can conclusively falsify a theory. Given that no scientific theory is tested in isolation, a negative experiment can always be attributed to components other than the theory we test – to the auxiliary hypotheses and background assumptions. How do scientists decide whether the experimental result undermines the theory or points at an error in the underlying assumptions? Duhem argues that we cannot offer a rule that (...) directs when the scientist should employ a radical or conservative strategy in light of a negative result, and ultimately they will appeal to their intuition. More recently philosophers have offered a number of strategies of how to locate error and justify the abandonment of a theory or an auxiliary hypothesis. This Element analyses Duhem's response to holism and subsequent accounts of how the problem can be resolved. (shrink)

This classic work in the philosophy of physical science is an incisive and readable account of the scientific method. Pierre Duhem was one of the great figures in French science, a devoted teacher, and a distinguished scholar of the history and philosophy of science. This book represents his most mature thought on a wide range of topics.

The Duhem-Quine Thesis is the claim that it is impossible to test a scientific hypothesis in isolation because any empirical test requires assuming the truth of one or more auxiliary hypotheses. This is taken by many philosophers, and is assumed here, to support the further thesis that theory choice is underdetermined by empirical evidence. This inquiry is focused strictly on the axiological commitments engendered in solutions to underdetermination, specifically those of Pierre Duhem and W. V. Quine. Duhem (...) resolves underdetermination by appealing to a cluster of virtues called 'good sense', and it has recently been argued by Stump (Stud Hist Philos Biol Biomed Sei, 18(1):149-159,2007) that good sense is a form of virtue epistemology. This paper considers whether Quine, who's philosophy is heavily influenced by the very thesis that led Duhem to the virtues, is also led to a virtue epistemology in the face of underdetermination. Various sources of Quinian epistemic normativity are considered, and it is argued that, in conjunction with other normative commitments, Quine's sectarian solution to underdetermination amounts to a skills based virtue epistemology. The paper also sketches formal features of the novel form of virtue epistemology common to Duhem and Quine that challenges the adequacy of epistemic value truth-monism and blocks any imperialist naturalization of virtue epistemology, as the epistemic virtues are essential to the success of the sciences themselves. (shrink)

This paper examines Duhem’s concept of good sense as an attempt to support a non rule-governed account of rationality in theory choice. Faced with the underdetermination of theory by evidence thesis and the continuity thesis, Duhem tried to account for the ability of scientists to choose theories that continuously grow to a natural classification. I will examine the concept of good sense and the problems that stem from it. I will also present a recent attempt by David Stump (...) to link good sense to virtue epistemology. I will argue that even though this approach can be useful for the better comprehension of the concept of good sense, there are some substantial differences between virtue epistemologists and Duhem. In the light of this reconstruction of good sense, I will propose a possible way to interpret the concept of good sense, which overcomes the noted problems and fits better with Duhem’s views on scientific method and motivation in developing the concept of good sense. (shrink)

Duhem’s concept of “good sense” is central to his philosophy of science, given that it is what allows scientist to decide between competing theories. Scientists must use good sense and have intellectual and moral virtues in order to be neutral arbiters of scientific theories, especially when choosing between empirically adequate theories. I discuss the parallels in Duhem’s views to those of virtue epistemologists, who understand justified belief as that arrived at by a cognitive agent with intellectual and moral (...) virtues, showing how consideration of Duhem as a virtue epistemologist offers insights into his views, as well as providing possible answers to some puzzles about virtue epistemology. The extent to which Duhem holds that the intellectual and moral virtues of the scientist determine scientific knowledge has not been generally noticed. (shrink)

David Stump has recently argued that Pierre Duhem can be interpreted as a virtue epistemologist. Stump’s claims have been challenged by Milena Ivanova on the grounds that Duhem’s ‘epistemic aims’ are more modest than those of virtue epistemologists. I challenge Ivanova’s criticism of Stump by arguing that she not distinguish between ‘reliabilist’ and ‘responsibilist’ virtue epistemologies. Once this distinction is drawn, Duhem clearly emerges as a ‘virtue-responsibilist’ in a way that complements Ivanova’s positive proposal that Duhem’s (...) ‘good sense’ reflects a conception of the ‘ideal scientist’. I support my proposal that Duhem is a ‘virtue-responsibilist’ by arguing that his rejection of the possibility of our producing a ‘perfect theory’ reflects the key responsibilist virtue of ‘intellectual humility’.Keywords: David Stump; Good sense; Humility; Milena Ivanova; Pierre Duhem; Virtue epistemology.

According to a view assumed by many scientists and philosophers of science and standardly found in science textbooks, it is controlled ex perience which provides the basis for distinguishing between acceptable and unacceptable theories in science: acceptable theories are those which can pass empirical tests. It has often been thought that a certain sort of test is particularly significant: 'crucial experiments' provide supporting empiri cal evidence for one theory while providing conclusive evidence against another. However, in 1906 Pierre Duhem (...) argued that the falsification of a theory is necessarily ambiguous and therefore that there are no crucial experiments; one can never be sure that it is a given theory rather than auxiliary or background hypotheses which experiment has falsified. w. V. Quine has concurred in this judgment, arguing that "our statements about the external world face the tribunal of sense experience not indi vidually but only as a corporate body". Some philosophers have thought that the Duhem-Quine thesis gra tuitously raises perplexities. Others see it as doubly significant; these philosophers think that it provides a base for criticism of the foundational view of knowledge which has dominated much of western thought since Descartes, and they think that it opens the door to a new and fruitful way to conceive of scientific progress in particular and of the nature and growth of knowledge in general. (shrink)

The "Duhem-Quine thesis" says that isolated hypotheses are not singularly verifiable by experience, only the whole body of a theory being able to be subjected to the test of experience. I first examine the rather divergent meanings this thesis takes when it is replaced in the different contexts of Duhem's and Quine'sphilosophies. Secondly, questions are asked about the acceptability of the thesis, its logical strength and its historical soundness. Finally, the consequences of some doubts raised by this inquiry (...) are examined especially with respect to Quine's philosophy. (shrink)

Duhem has generally been understood to have maintained that the major Greek astronomers were instrumentalists. This view has emerged mainly from a reading of his 1908 publication To Save the Phenomena. In it he sharply contrasted a sophisticated Greek interpretation of astronomical models (for Duhem this was that they were mathematical contrivances) with a naive insistence of the Arabs on their concrete reality. But in Le Système du monde, which began to appear in 1913, Duhem modified his (...) views on Greek astronomy considerably; his more subtle understanding included the recognition that many Greeks subordinated mathematical astronomy to physical theory. But he could not completely repudiate his earlier views about Greek astronomy in part because his extreme nineteenth century prejudices led him to continue to insist on a clear-cut demarcation between Greek and Arabic astronomy. The inevitable result is a certain unevenness in the Système and some glaring inconsistencies. (shrink)

ABSTRACT The emerging consensus in the secondary literature on Duhem is that his notion of ‘good sense’ is a virtue of individual scientists that guides them choosie between empirically equal rival theories : 149–159; Ivanova 2010. “Pierre Duhem’s Good Sense as a Guide to Theory Choice.” Studies in History and Philosophy of Science Part A 41 : 58–64; Fairweather 2011. “The Epistemic Value of Good Sense.” Studies in History and Philosophy of Science Part A 43 : 139–146; Bhakthavatsalam. (...) “Duhemian Good Sense and Agent Reliabilism.” Studies in History and Philosophy of Science Part A 64: 22–29). In this paper, I argue that good sense is irrelevant for theory choice within Duhem’s conception of scientific methodology. Theory choice, for Duhem, is either a pseudo-problem or addressed purely by empirical and formal desiderata depending on how it is understood. I go on to provide a positive interpretation of good sense as a feature of scientific communities that undergo particular forms of education that allow scientists to abandon theory pursuit. I conclude by suggesting that this interpretation entails that virtue epistemological readings of Duhem are insufficient for understanding good sense; we must employ a social epistemological perspective.

When the results of an experiment appears to disconfirm a hypothesis, how does one know whether it’s the hypothesis, or rather some auxiliary hypothesis or assumption, that is at fault? Philosophers’ answers to this question, now known as “Duhem’s problem,” have differed widely. Despite these differences, we affirm Duhem’s original position that the logical structure of this problem alone does not allow a solution. A survey of philosophical approaches to Duhem’s problem indicates that what allows any philosopher, (...) or scientists for that matter, to solve this problem is the addition of epistemic information that guides their assignment of praise and blame after a negative test. We therefore advocate a distinction between the logical and epistemic formulations of Duhem’s problem, the latter relying upon additional relevant information about the system being tested. Recognition of the role of this additional information suggests that some proposed solutions to the epistemic form of Duhem’s problem are preferable over others. (shrink)

Duhem is often described as an anti-realist or instrumentalist. A contrary view has recently been expressed by Martin (1991) (Pierre Duhem: Philosophy and History in the Work of a Believing Physicist (La Salle, IL: Open Court)), who suggests that this interpretation makes it difficult to understand the vantage point from which Duhem argues in La science allemande (1915) that deduction, however impeccable, cannot establish truths unless it begins with truths. In the same spirit, the present paper seeks (...) to establish that Duhem is at any rate not the kind of anti-realist he is often presented as being, and that his views are like those Quine sees fit to call realist. An interpretation of Duhem's views on explanation and precision in science, and their bearing on the epistemological status of theory, is advanced which leads naturally into his critique of conventionalism. His attitude towards atomism, which should not be judged from a post-1925 perspective, is considered part of the unified view he strove after and appropriately called Duhem's physicalism, standing in contrast to the kind of reductionist conception usually associated with atomism. (shrink)

I argue that the Bayesian Way of reconstructing Duhem's problem fails to advance a solution to the problem of which of a group of hypotheses ought to be rejected or "blamed" when experiment disagrees with prediction. But scientists do regularly tackle and often enough solve Duhemian problems. When they do, they employ a logic and methodology which may be called error statistics. I discuss the key properties of this approach which enable it to split off the task of testing (...) auxiliary hypotheses from that of appraising a primary hypothesis. By discriminating patterns of error, this approach can at least block, if not also severely test, attempted explanations of an anomaly. I illustrate how this approach directs progress with Duhemian problems and explains how scientists actually grapple with them. (shrink)

Duhem attempted to find a middle way between two positions he regarded as extremes, the conventionalism of Poincaré and the scientific realism of the majority of his scientific colleagues. He argued that conventionalism exaggerated the arbitrariness of scientific formulations, but that belief in atoms and electrons erred in the opposite direction by attributing too much logical force to explanatory theories. The instrumentalist sympathies so apparent in Duhem's writings on the history of astronomy are only partially counterbalanced by his (...) view that science is progressing toward a natural classification of the world. (shrink)

Duhem's 1908 essay questions the relation between physical theory and metaphysics and, more specifically, between astronomy and physics–an issue still of importance today. He critiques the answers given by Greek thought, Arabic science, medieval Christian scholasticism, and, finally, the astronomers of the Renaissance.

I reject the widely held view that Duhem's 1906 book La Théorie physique is a statement of instrumentalistic conventionalism, motivated by the scientific crisis at the end of the nineteenth century. By considering Duhem's historical context I show that his epistemological views were already formed before the crisis occured; that he consistently supported general thermodynamics against the new atomism; and that he rejected the epistemological views of the latter's philosophical supporters. In particular I show that Duhem rejected (...) Poincaré's account of scientific language, Le Roy's view that laws are definitions, and the conventionalist's use of simplicity as the criterion of theory choice. Duhem regarded most theory choices as decidable on empirical grounds, but made historical context the main determining factor in scientific change. (shrink)

Duhem's discussion of physical theories as natural classifications is neither antithetical nor incidental to the main thrust of his philosophy of science. Contrary to what is often supposed, Duhem does not argue that theories are better thought of as economically organizing empirical laws than as providing information concerning the nature of the world. What he is primarily concerned with is the character and justification of the scientific method, not the logical status of theoretical entities. The crucial point to (...) notice is that he took the principle of the autonomy of physics to be of paramount importance and he developed the conception of natural classification in opposition to accounts of physical theories that contravened it. (shrink)

In Chapter 4 of [2] Grünbaum sets out to refute Einstein's philosophy of physical geometry. The latter's theory is seen as lying within the tradition of "anti-empiricist conventionalism" of Duhem and Quine as opposed to the "qualified empiricism" of Poincaré, Carnap and Reichenbach. Consequently Grünbaum sets the stage for his critique of Einstein by discussing certain of the views of these other thinkers. But in these preliminary discussions the various theses are confused and misrepresented in such a way as (...) to make it almost impossible to evaluate Grünbaum's final treatment of Einstein's thesis. For this reason I will deal only with those parts of this chapter in which the roots of Grünbaum's confusion are to be found. This will involve analyses of two theories which are not clearly distinguished by Grünbaum. The first is Duhem's denial of the "crucial experiment" in physics; the second is Quine's version of "pragmatism.". (shrink)

As in the case of great books in all branches of philosophy, Pierre Duhem's Le Théorie Physique , first published in 1906, can be looked to as the progenitor of many different and even conflicting currents in subsequent philosophy of science. On a superficial reading, it seems to be an expression of what later came to be called deductivist and instrumentalist analyses of scientific theory. Duhem's very definition of physical theory, put forward early in the book, is the (...) quintessence of instrumentalism: A physical theory is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which aim to represent as simply, as completely, and as exactly as possible a set of experimental laws [p. 19].

Galileo's view of science is indebted to the teaching of the Jesuit professors at the Collegio Romano, but Galileo's concept of mathematical physics also corresponds to that of Giovan Battista Benedetti. Lacking documentary evidence that would connect Benedetti directly with the Jesuits, or the Jesuits with Benedetti, I infer a common source: the Spanish connection, that is, Domingo de Soto. I then give indications that the fourteenth-century work at Oxford and Paris on calculationes was transmitted via Spain and Portugal to (...) Rome and other centers where Jesuits had colleges, and figured in the rise of mathematical physics at the beginning of the seventeenth century. A result of these researches is their vindication of Duhem, as contrasted with Koyré, on the origins of modern mechanics. (shrink)

Duhem's and Quine's holistic theses, when properly understood, allow methodologically responsible ways of resolving a conflict between a theoretical system and experience; they only deny the possibility of doing it in an epistemically persuasive way. By developing a "string" model of scientific tests I argue that the pattern of interaction between the elements of a theoretical system arising in response to multiple adverse data can be helpful in locating a "weak spot" in it. Combining this model with anti-holistic arguments (...) of Popper, Greenwood, and Lakatos significantly reinforces their joint power. (shrink)

The bulk of Duhem's writing which bears on the understanding of mixtures suggests he adopted an Aristotelian position which he opposed only to the atomic view. A third view from antiquity-that of the Stoics-seems not to be taken into account. But his lines of thought are not always as explicit as could be wished. The Stoic view is considered here from a perspective which Duhem might well have adopted. This provides a background against which his somewhat unorthodox Aristotelianism (...) might be understood.

The following is an essay review of Paul Needham's translation of Pierre Duhem's Lemixte et la combinaison chimique and a numberof other essays. In this review we describe theintent and general features of Le mixte and try to place it in the larger context of Duhem'sprogram for energetics. The long essay (Essay3) opposing Marcellin Berthelot'sthermochemistry is singled out for detailedcommentary, since it gives Duhem's reasons forendorsing Josiah Willard Gibbs's chemicalstatics. We argue that a chemical mechanics ofa Gibbsian (...) sort, defended in Le mixte and otheressays in this volume, was the inspiration for,and basis of, Duhem's energetics. Needham'swelcome translations help an English-languageaudience to better understand the basiccontours of Duhem's important, if ultimatelymisguided, project. We conclude with somecomments on the difficulties in translatingDuhem and on the quality of the translationsNeedham has provided. (shrink)

The Duhem?Quine thesis asserts that any empirical evaluation of a theory is in fact a composite test of several interconnected hypotheses. Recalcitrant evidence signals falsity within the conjunction of hypotheses, but logic alone cannot pinpoint the individual element(s) inside the theoretical cluster responsible for a false prediction. This paper considers the relevance of the Duhem?Quine thesis for experimental economics. A starting point is to detail how laboratory evaluations of economic hypotheses constitute composite tests. Another aim is to scrutinize (...) the strategy of conducting a series of experiments in order to hem in the source(s) of disconfirmative evidence. A Bayesian approach is employed to argue that reproducing experiments may be useful in terms of identifying plausible causes of recalcitrant data. (shrink)

The rejection of the idea that the so‐called Duhem‐Quine thesis in fact expresses a thesis upheld by either Duhem or Quine invites a more detailed comparison of their views. It is suggested that the arguments of each have a certain impact on the positions maintained by the other. In particular, Quine's development of his notion of ontological commitment is enlisted in the interpretation of Duhem's position. It is argued that this counts against the instrumentalist construal usually put (...) on what Duhem says about approximation and historical continuity. (shrink)

Abstract The Duhem?Quine thesis is generally presented as the radical underdetermi? nation of a theory by experimental evidence. But there is a much?neglected second aspect, i.e. the coherence or interrelatedness of the conceptual components of a theory. Although both Duhem and Quine recognised this aspect, they failed to see its consequences: it militates against the idea of radical underdetermination. Because scientific theories are coherent conceptual systems, empirical evidence penetrates, as it were, the periphery and allows the localisation of (...) central, not just peripheral hypotheses. There is then no reason to deny the existence of crucial experiments. Both these ideas are denied in the Quine?Duhem thesis. A discussion of the famous Stem?Gerlach experiment and the role of fundamental physical constants shows, however, that localisation is not only possible but essential for the validity of scientific theories. Quine's famous ?latitude of choice? turns out to be severely restricted. (shrink)
