In this paper I argue for the idea that, throughout the history of science, there are some cases of theory change that would show how science develops with no referential continuity. For this purpose, I analyze Psillos’ proposal of a theory of reference used to account for referential continuity in conceptual transitions. This kind of continuity is requested by Psillos —as by other philosophers— in his defense of scientific realism. By means of a historical case, the theory of germplasm of (...) August Weismann, I intend to demonstrate that Psillos’ demand for reference continuity can be found to be inadequate. DOI:10.5007/1808-1711.2010v14n3p335. (shrink)

Operationalism and theoretical entities. The thesis of the“theory ladenness” of observation leads to an antinomy. In order to solve this antinomy a technical operationalism is sketched, according to which theories should in principle not contain anything that cannot be reduced to technical procedures. This implies the rejection of Quine's underdeterminacy thesis and of many views about the theoretical-observational distinction, e.g. neopositivistic views, van Fraassen's view, Sneed-Stegmüller's view. Then I argue for the following theses: 1. All scientific concepts are theory laden (...) in the sense that they allow us to anticipate possible experiences, but they have to be in principle fully observable, i.e. integrally convertible into operational-technical applications. 2. The observation/theory distinction can be maintained as a historical one: what is observable depends on the instruments that are available at any stage of the development of science. 3.In principle theoretical entities are empirically real in Hacking's sense. However, some aspects of Hacking's realism are to be criticized. Theoretical entities are to be resolved into the totality of the interrelated properties accessible to us by means of theoretical points of view embodied in scientific instruments. (shrink)

The discussion presents a framework of concepts that is intended to account for the rationality of semantic change and variation, suggesting that each scientific concept consists of three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept’s use. I argue that in the course of history a concept can change in any of these components, and that change in the concept’s inferential role and reference can be accounted for as being rational relative (...) to the third component, the concept’s epistemic goal. This framework is illustrated and defended by application to the history of the gene concept. It is explained how the molecular gene concept grew rationally out of the classical gene concept despite a change in reference, and why the use and reference of the contemporary molecular gene concept may legitimately vary from context to context.

In this article, the impact of Thomas Kuhn’s The Structure of Scientific Revolutions on the sociology of science is evaluated. The main argument is that a questionable construction of Kuhn’s work heralded the constructivist revolution that ultimately contributed to the division between sociology of science and sociology of scientific knowledge. A reorientation of sociology of science that combines institutional and constructivist perspectives is advocated.

Part of teaching the descriptive phenomenological psychological method is to assist students in grasping their previously unrecognized assumptions regarding the meaning of “science.” This paper is intended to address a variety of assumptions that are encountered when introducing students to the descriptive phenomenological psychological method pioneered by Giorgi. These assumptions are: 1) That the meaning of “science” is exhausted by empirical science, and therefore qualitative research, even if termed “human science,” is more akin to literature or art than methodical, scientific (...) inquiry; 2) That as a primarily aesthetic, poetic enterprise human scientific psychology need not attempt to achieve a degree of rigor and epistemological clarity analogous to that pursued by natural scientists; 3) That “objectivity” is a concept belonging to natural science, and therefore human science ought not to strive for objectivity because this would require “objectivizing” the human being; 4) That qualitative research must always adopt an “interpretive” approach, description being seen as merely a mode of interpretation. These assumptions are responded to from a perspective drawing primarily upon Husserl and Merleau-Ponty, but also upon Eagleton’s analysis of aestheticism. (shrink)

In this essay it is argued that (1) if the process of scientific inquiry were to continue foreever, then science would ultimately terminate in the acceptance of a single theoretical framework better than all conceivable others, and (2) there is some evidence in favor of the view that science will continue unto eternity but no evidence in favor of the contrary view. In arguing for claim (1) it is claimed that if we are to understand the sense in which science (...) is progressive we must mean either that science progresses by approximating a final goal which, given an infinite process, will be attained, or that science progresses simply in the sense of expanding a body of funded knowledge such that, given an infinite process, the body of funded knowledge expands ad infinitum. That the second member of this disjunct is false and that the first cannot be shown to be false follows largely from a discussion and rejection of all available arguments (five) against the hypothesis proposed in (1). Further, an argument provided by Peirce (and suitably supplemented) provides additional positive evidence for the truth of the first member. No such argument exists for the truth of the second member. In arguing for claim (2) it is held that evidence in favor of a belief can be purchased by the positive moral value likely to occur as a result of accepting the beliefs, and that there is at least one moral value which accrues to the belief that inquiry will continue forever but which does not accrue to the belief that inquiry will not continue forever. In short, while there is no systematic evidence for or against the view that inquiry will continue forever, we have the right (and duty) to believe that inquiry will continue forever but we do not have the right (and duty) to believe the contrary.

In this article, I discuss Gadamer's hermeneutic account of understanding as an alternative to Kuhn's incommensurability thesis. After a brief account of Kuhn's aesthetic account and arguments against it, I argue that the linguistic account faces a paradox that results from Kuhn's objectivist account of understanding, and his lack of historical reflexivity. The statement 'Languages are incommensurable' is not a unique view of language, and is thus subject to contest by incommensurable readings. Resolving the paradox requires an account of incommensurability (...) that is self-referentially consistent, open-ended, and historically reflexive whereby we recognize that our very interest in incommensurability is historically conditioned. By meeting these conditions, Gadamer's account of historical understanding offers a middle ground between two extremes: on the one side is the claim that understanding involves becoming a native of an incommensurable language, and on the other side is the rejection of the prospect of understanding a contextually removed language altogether. Gadamer is discussed as a mediator between Kuhn's epistemic and historical projects, and thus paves the way for a new hermeneutics of science. The notions of traditional horizon, historically effected consciousness, the universality of interpretation, alienation, dialogical openness, and the fusion of horizons are also discussed. (shrink)

Realism about progress--that progress consists in the obtaining of some metaphysical relation between a sequence of theories and the world--is often thought to be required by realism about the representational character of theories. The purpose of this paper is to show how one can be a realist about theories without being a realist about progress. The result is a view that cannot be at odds with what the history of science shows.

In his late years, Thomas Kuhn became interested in the process of scientific specialization, which does not seem to possess the destructive element that is characteristic of scientific revolutions. It therefore makes sense to investigate whether and how Kuhn’s insights about specialization are consistent with, and actually fit, his model of scientific progress through revolutions. In this paper, I argue that the transition toward a new specialty corresponds to a revolutionary change for the group of scientists involved in such a (...) transition. I will clarify the role of the scientific community in revolutionary changes and characterize the incommensurability across specialties as possessing both semantic and methodological aspects. The discussion of the discovery of the structure of DNA will serve both as an illustration of my main argument and as reply to one criticism raised against Kuhn—namely, that his model cannot capture cases of revolutionary yet non-disruptive episodes of scientific progress. Revisiting Kuhn’s ideas on specialization will shed new light on some often overlooked features of scientific change. (shrink)

Benton Stidd has defended the position that punctuationists are not wrong about the inadequacy of the synthetic theory of evolution for explaining evolution. The thrust of his defense is that arguments to the contrary by Thompson involve a rational reconstruction along logical empiricist lines, which is insensitive to historical and social forces in a way that the Kuhnian Weltanschauung view that he espouses is not. I argue in this paper that Stidd has entirely misunderstood my arguments, that the soundness of (...) my arguments does not depend on acceptance of logical empiricism, and that Stidd fails to establish that punctuated equilibria is a new "paradigm".

Die Arbeit betrachtet die verschiedenen Ansichten, die über wissenschaftliche Objektivität bestehen: Etwa als Charakteristik einer gesamtwissenschaftlichen Praxis, als Gesamtfortschritt, der durch die Struktur der Institution bestimmt ist, oder als etwas, was auf subjektivem Glauben, subjektivem Verfahren und kollektiven Meinungen begründet ist.

Reichenbach's well-known distinction between the context of discovery and the context of justification has recently come under attack from several quarters. In this paper I attempt to reconsider the distinction and evaluate various recent criticisms of it. These criticisms fall into two main groups: those which directly challenge Reichenbach's distinction; and those which (I argue) indirectly but no less seriously challenge that distinction by rejecting the related distinction between psychology and epistemology, and defending the "naturalizing" of epistemology. I argue that (...) these recent criticisms fail, and that the distinction remains an important conceptual tool necessary for an adequate understanding of the way in which scientific claims purport to appropriately portray our natural environment.

Assessing the hydrogeological modeling at the Yucca Mountain and Maxey Flats nuclear repositories reveals a number of important ways in which theory choice can go wrong. The two cases suggest that there are at least six important criteria for evaluating the suitability of scientific models to be used for predictions intended to serve public policy. More generally, the paper argues that applied philosophy of science, as practiced in environmental policymaking, requires one to employ ethical rationality as well as scientific rationality, (...) to heed the advice of the moral philosopher, not merely that of the epistemologist or philosopher of science.

Simple assumptions represent a decisive reason to prefer one theory to another in everyday scientific praxis. But this praxis has little philosophical justification, since there exist many notions of simplicity, and those that can be defined precisely strongly depend on the language in which the theory is formulated. The language dependence is a natural feature—to some extent—but it is also believed to be a fatal problem, because, according to a common general argument, the simplicity of a theory is always trivial (...) in a suitably chosen language. But, this trivialization argument is typically either applied to toy-models of scientific theories or applied with little regard for the empirical content of the theory. This paper shows that the trivialization argument fails, when one considers realistic theories and requires their empirical content to be preserved . In fact, the concepts that enable a very simple formulation, are not necessarily measurable, in general. Moreover, the inspection of a theory describing a chaotic billiard shows that precisely those concepts that naturally make the theory extremely simple are provably not measurable. This suggests that—whenever a theory possesses sufficiently complex consequences—the constraint of measurability prevents too simple formulations in any language. This explains why the scientists often regard their assessments of simplicity as largely unambiguous. In order to reveal a cultural bias in the scientists’ assessment, one should explicitly identify different characterizations of simplicity of the assumptions that lead to different theory selections. General arguments are not sufficient. (shrink)

This paper revisits one of the key ideas developed in The Structure of Scientific Revolutions. In particular, it explores the methodological form of incommensurability which may be found in the original edition of Structure. It is argued that such methodological incommensurability leads to a form of epistemic relativism. In later work, Kuhn moved away from the original idea of methodological incommensurability with his idea of a set of epistemic values that provides a basis for rational theory choice, but do not (...) constitute an algorithm for such choice. The paper also explores the sceptical basis for the epistemic relativism of the original view that Kuhn proposes in Structure. It suggests that the main sceptical rationale for such relativism may be avoided by a particularist and naturalist conception of epistemic normativity. When this approach is combined with the appeal to external methodological standards endorsed by the later Kuhn and his critics, the epistemic relativism of Structure may be completely repudiated.

The interpretive plasticity of Kuhn’s philosophical work has been reinforced by readings informed by other philosophical, historiographic or sociological projects. This paper highlights several aspects of Kuhn’s work that have been neglected by such readings. First, Kuhn’s early contribution to several subsequent philosophical developments has been unduly neglected. Kuhn’s postscript discussion of “exemplars” should be recognized as one of the earliest versions of a conception of theories as “mediating models.” Kuhn’s account of experimental practice has also been obscured by readings (...) that assimilate his views to Quinean holism. Second, three distinctive Kuhnian themes have been insufficiently recognized. Kuhn’s challenge to received philosophical views has been domesticated by reading him as offering an alternative conception of scientific knowledge. Kuhn is better understood as rejecting knowledge-centric accounts altogether, in favor of understanding the practice of research. Kuhn’s conception of that activity, as conceptual “articulation,” has accordingly also not been given its due. Finally, Kuhn’s career-long insistence on the mutual accountability of philosophy of science and the philosophy of mind and language calls attention to the extent to which these fields have now drifted apart.

Este artigo tem como objetivo discutir algumas das teses centrais do físico teórico e epistemólogo John Michael Ziman relativas à dimensão social da ciência. Ziman sustenta que, para um melhor entendimento das mudanças ocorridas na prática científica contemporânea, sobretudo das consequências geradas nas últimas décadas pelo que ele denominou de "ciência pós-acadêmica", é necessária uma abordagem que inclua aspectos não somente filosóficos, mas também sociológicos e históricos. Segundo Ziman, a supervalorização, na ciência pós-acadêmica, de valores ligados a uma cultura gerencial (...) tem como consequências, a curto prazo, a alteração do éthos mertoniano e dos princípios filosóficos utilizados historicamente pelos cientistas como ideais reguladores; e, a longo prazo, a redução da capacidade cognitiva da ciência de produzir "novos mapas" da realidade. Ao analisar alguns conceitos-chave da obra de Ziman, tais como "consensibilidade", "consensualidade", "conhecimento público" e "ciência pós-acadêmica", esperamos debater a concepção de ciência desse autor, ainda pouco citado no Brasil. The main objective of this article is to discuss some of the central theses on the work of the physicist and epistemologist John Michael Ziman concerned with the social dimension of science. Ziman supports the thesis that in order to have a better understanding of the recent changes in scientific practice, especially the consequences brought by a new mode of knowledge production, in the last decades, which he names "post-academic", it is necessary a new methodological approach is necessary that includes, not only philosophical aspects, but also sociological and psychological ones. According to Ziman, one of the consequences of the overvaluation of a managerial culture in post academic science is, in the short term, the deflation of the Mertonian ethos and also of the philosophical principles which were historically shared amongst scientists as regulatory ideals; and in the long run, the major consequence of post-academic science would be the reduction of cognitive capacity of science to produce "new maps" of the world. By the analysis of some key-concepts in Ziman's work, such as "consensibility", "consensuality", "public knowledge" and "post-academic science", we aim to make the Brazilian reader acquainted with his conception of science.

This paper reconsiders the relation between Kantian transcendental reflection and 20th century philosophy of science. As has been pointed out by Michael Friedman and others, the notion of a "relativized a priori" played a central role in Rudolf Carnap's, Hans Reichenbach's and other logical empiricists' thought. Thus, even though the logical empiricists dispensed with Kantian synthetic a priori judgments, they did maintain a crucial Kantian doctrine, viz., a distinction between the level of establishing norms for empirical inquiry and the level (...) of norm-governed inquiry itself. Even though Thomas Kuhn's theory of scientific revolutions is often taken to be diametrically opposed to the received view of science inherited from logical empiricism, a version of this basically Kantian distinction is preserved in Kuhn's thought. In this respect, as Friedman has argued, Kuhn is closer to Carnap's theory of linguistic frameworks than, say, W.V. Quine's holistic naturalism. Kuhn, indeed, might be described as a "new Kant" in post-empiricist philosophy of science. This article examines, first, the relativization of the Kantian a priori in Reichenbach's work, arguing that while Reichenbach criticized "transcendentalism", he nevertheless retained, in a reinterpreted form, a Kantian-like transcendental method, claiming that the task of philosophy is to discover and analyze the presuppositions underlying the applicability of conceptual systems. Then, some reflections on Kuhn's views on realism are offered, and it is suggested that Kuhn can be reinterpreted as a Kantian transcendental idealist. Given the central importance of Kuhnian themes in contemporary philosophy of science, it is no exaggeration to claim that Kantian transcendental inquiry into the constitutive principles of empirical knowledge, and even transcendental idealism, still have a crucial role to play in this field and deserve further scrutiny.

This essay reviews two recent books commenting on, and contributing to, the “science wars.” In Who Rules in Science? James Robert Brown respectfully but firmly rejects the “nihilist” and the “naturalist” wings of social constructivism. He rejects attempts to debunk science in the name of a relativist or anarchist epistemology. He also criticizes the “strong programme” in the sociology of knowledge and its implied contrast between reasons and causes. In Prometheus Bedeviled Norman Levitt examines the cultural roots of current discontent (...) with science. Levitt's analysis—and polemic—charges contemporary culture with a pervasive cheapening of intellectual standards. (shrink)

Focused on the notion of the threshold of objectivity, my article dissects the empirical mirror-glass of the philosophy of Joseph Melançon. I propose to thrust this emblematic perspective of determinist discourse against the literary turn, acclaimed for its underpinning ambiguous subjectivity – here notably made relevant by Pierre Bourdieu. Both discursive practices complete each other and reject each other in a self-feeding spiral: incessant motivation for a hybrid, vexing study of mutual tensions.

Idealist Heresies in Philosophy of Science: Cassirer, Carnap, and Kuhn. As common wisdom has it, philosophy of science in the analytic tradition and idealist philosophy are incompatible. Usually, not much effort is spent for explaining what is to be understood by idealism. Rather, it is taken for granted that idealism is an obsolete and unscientific philosophical account. In this paper it is argued that this thesis needs some qualification. Taking Carnap and Kuhn as paradigmatic examples of positivist and postpositivist philosophies (...) of science it is shown that these accounts share important features with Cassirer's idealist philosophy of science developed in the first half of this century. As it turns out, often Cassirer is more modern than those classical philosophers of (post)posivitist philosophy of science. For instance, Quine's criticism against Carnap's empiricist philosophy of science launched in Two Dogmas of Empiricism is anticipated by Cassirer for several decades. (shrink)

In The Structure of Scientific Inference, Mary Hesse has argued for a realist interpretation of science. Her realism, however, is not to be understood in the context of the traditional realist/instrumentalist debate within the philosophy of science. That debate focused on the question of whether or not science did anything other than systematize the empirical data given in our experience. The traditional realist answered “yes” and most frequently described the theoretical statements of science, not only as true, but also as (...) providing descriptions of the world. The instrumentalist on the other hand answered “no” and ascribed no descriptive force to the theoretical statements of science. However, according to Hesse, neither party in the contemporary realism debate assumes the notion of an empirical given. Consequently, the present dispute must be understood as taking place on a level which is logically prior to its predecessor. (shrink)

In his valuable book [3], Israel Scheffler presents an extended critique of Thomas Kuhn's philosophy of science. Scheffler argues against Kuhn's “main thesis,” namely that “... paradigm change in science is not generally subject to deliberation and critical assessment”. Scheffler does recognize, though, that there are important elements of Kuhn's view that themselves seem to conflict with this “main thesis.” For these elements seem to make possible deliberation, critical assessment, and objectivity in the discussion of scientific paradigms. So it appears (...) from Scheffler's critique that Kuhn's position is inconsistent. The puzzle is compounded by Kuhn's admission—indeed, insistence—that his book does contain “a preliminary codification of good reasons for theory choice. These are... reasons of exactly the kind standard in philosophy of science: accuracy, scope, simplicity, fruitfulness, and the like”. In his recent reply to Kuhn, Scheffler quotes this passage from Kuhn and says: “If these reasons are not... to be construed as utterly free of all constraints or themselves paradigm-dependent, then they allow the comparison of rival paradigms and make paradigm debates intelligible. Such intelligibility is, however, at odds with Kuhn's statement that the proponents of competing paradigms ‘will inevitably talk through each other’”. In this interchange between Scheffler and Kuhn, one gets the impression of people, if not paradigms, talking “through each other.” I think that this nonmeeting of minds is due to interpreting Kuhn as an opponent of objectivity when in fact he is not an opponent but a proponent. It is this misinterpretation which produces the apparent inconsistency in Kuhn's position. In this paper I suggest a way of understanding Kuhn which resolves this apparent inconsistency in his work and might help to focus discussion on the real issue between Kuhn and many of his critics. This suggestion has the crucial consequence of shifting the focus from objectivity to the real issue, namely truth. (shrink)

Approaches to the analysis of theory choice in science studies often focus either on objective criteria or subjective values for evaluating theories or on critical experiments for testing theories. In the present article a historical case study in the biomedical sciences is reconstructed, in which experimentation was performed to choose between two competing theories of blood coagulation. Analysis of this case study reveals that experimentation exhibits a particular structure, composed of design, execution, and results, and specific characteristics, consisting of controllability, (...) reproducibility, plasticity, and fecundity. Although this structure and these characteristics are not used to replace objective criteria or subjective values of theory evaluation or to define critical experiments, they are instrumental for analyzing and understanding theory choice.

The object of this paper is twofold: to show that resistance to scientific change on the part of scientists need signal neither irrationality nor the presence of extra-scientific influences; and to show how such resistance can be accommodated within a theory of rational choice. After considerations have been outlined suggesting that scientists cannot rationally resist new scientific theories unless theory choice is subjectivistic (section I), evidence is adduced favoring the contrary view (section II). In section III, a non-subjectivistic, non-relativistic conception (...) of rational choice is proposed which recognizes the possibility of scientists' rationally resisting new scientific developments. Finally, in section IV, some minor misunderstandings concerning resistance are discussed. (shrink)

Science depends on judgments of the bearing of evidence on theory. Scientists must judge whether an observation or the result of an experiment supports, disconfirms, or is simply irrelevant to a given hypothesis. Similarly, scientists may judge that, given all the available evidence, a hypothesis ought to be accepted as correct or nearly so, rejected as false, or neither. Occasionally, these evidential judgments can be made on deductive grounds. If an experimental result strictly contradicts a hypothesis, then the truth of (...) the data deductively entails the falsity of the hypothesis. In the great majority of cases, however, the connection between evidence and hypothesis is non-demonstrative, or inductive. In particular, this is so whenever a general hypothesis is inferred to be correct on the basis of the available data, since the truth of the data will not deductively entail the truth of the hypothesis. It always remains possible that the hypothesis is false even though the data are correct. (shrink)

The causal theory of reference is often taken to provide a solution to the problems, such as incomparability and referential discontinuity, that the meaning-change thesis raised. I show that Kuhn successfully questioned the causal theory and Putnam's idea that reference is determined via the sameness relation of essences that holds between a sample and other members of a kind in all possible worlds. Putnam's single ‘essential' properties may be necessary but not sufficient to determine membership in a kind category. Kuhn (...) argued that extension is fixed by similarity-dissimilarity relations that are liable to change in taxonomic reorganizations of science. *Received October 2009; revised January 2010. †To contact the author, please write to: Institute of Philosophy, University of Leiden, Martin de Vrieshof 4, 2300 RS Leiden, The Netherlands; e-mail: [email protected].

To whom, if anyone, are the writings of philosophers of science relevant? There are three potential groups of people: Philosophers, Scientists, and Interested Citizens, within and beyond the academy.

My essay is in dialogue with a characteristically insightful lecture given thirty years ago by Arthur Fine. Addressing the Philosophy of Science Association as its president, Fine argued that general philosophy (...) of science was dead, and that all the action lay in the philosophy of the special sciences. I try to identify what was correct about Fine’s diagnosis, while supplementing his message by describing fruitful projects that have since emerged. I also hope to share his subversive spirit.

The purpose of this paper is to introduce an approach to clinical practice aiming to resolve the dilemma of choosing between a mechanistic and a phenomenological model. The approach is an extension of Polanyi's epistemology. Michael Polanyi, devised an epistemology of science which overcomes the problem of detachment, inherent in the mechanistic approach, and resolves the problem of subjectivity troubling phenomenologists. His epistemology is known as Personal Knowledge. An extension of this epistemology, a Neo-Polanyian proposal, is offered as a more (...) successful model for clinical practice than previous suggestions addressing the dilemma. (shrink)

In scientific explanations, the explanans theory is sometimes incommensurable with the explanandum empirical data. How is this possible, especially when the explanation is deductive in nature? This paper attempts to solve the puzzle without relying on any particular theory of reference. For us, it is rather obvious that the geometric idea of projection plays a key role in Keplers explanation of Tycho Brahes empirical data. We discover that a similar mechanism operates in theoretic explanations in general. In short, all theoretic (...) explanations are projective explanations. If so, there should be no logical reason why explanans theories cannot be incommensurable with explanandum data. For illustration, we analyse Einsteins explanation of the results of the Michelson–Morley experiment in some detail. (shrink)

: Testing the claims that scientists make is extremely difficult. Testing the claims that philosophers of science make about science is even more difficult, difficult but not impossible. I discuss three efforts at testing the sorts of claims that philosophers of science make about science: the influence of scientists' age on the alacrity with which they accept new views, the effect of birth order on the sorts of contributions that scientists make, and the role of novel predictions in the acceptance (...) of new scientific views. Without attempting to test philosophical claims, it is difficult to know what they mean. (shrink)

Feminist approaches in epistemology and philosophy of science have frequently been labelled as ’relativist’, both by feminist as well as by non-feminist philosophers. Regularly the so labelled distance themselves from even the mere suspicion of relativist tendencies. There is a remarkable discrepancy between an attributed and a self-declared relativism. Taking the self-declared relativism of Lorraine Code as an example, the article argues that it is a case of a rhetorical not epistemological relativism, better termed as anti-anti-relativism, but that there are (...) nevertheless good reasons for feminists to follow Code along that path.

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].

If, as it is usually understood, incommensurable theories must be compatible then one need never choose between two such theories. But if theories were incompatible and incommensurable one would have to choose between them. What if they are incompatible only outside the domain of observation? The fact that Darwin's biology can clash with Kelvin's physics (each with their respective auxiliary assumptions) regarding the age of the earth shows how commensurable theories may yet be incompatible. But it also shows that they (...) need not be alternatives--i.e. that one may not be able to simply and satisfactorily replace the other in our world view. But standard examples of scientific revolutions consist of the replacement of one theory by another in one's world view. These alternative theories must therefore be more than merely incompatible--what do they share if not content? (I.e. they must be commensurable.). (shrink)
