This article analyses an episode in the earlyhistory of quantum theory: the controversy betweenPauli and Heisenberg about the anomalous Zeemaneffect, which was a main stumbling block for the oldquantum theory of Bohr. It is argued that theindividual philosophical views of both Pauli andHeisenberg directed their attempts to solve theanomaly and decisively influenced the solutions theyproposed. The results of this case study arecompared with the assertions of four theories ofscientific change, namely those of Kuhn, Lakatos,Laudan and Giere.

The article presents a brief reconstruction of naturalized epistemology, understood as a methodological approach. Three emblematic positions within naturalized epistemology are distinguished: rejection of apriorism inepistemology, favoring the use of the results of empirical science; attribution of an instrumental normativity to epistemology; and the thesis of the empirical assessability of the epistemic norms or principles. The text addresses the way in which, historically, these features are presented in the foundational works of Quine and Laudan. Furthermore, it studies how this project (...) is applied by three authors: Howard Sankey, who links naturalism to the debate of epistemic relativism; and Louise Antony and Elizabeth Anderson, who make use of these ideas as a foundation for feminist epistemology. Through these “applications”, it is possible to appreciate that naturalizedepistemology does not lead to the elimination of normative aspects, as was feared by early critics of Quine. It is also possible to appreciate that the approach of Sankey is naturalized because it is empirically informed, but it still depends on a priori arguments. On the contrary, appropriations by feminist epistemology carry out the naturalization project in a deeper sense, that is, they introduce a set of epistemological premises that are themselves empirical.

Several forms of naturalism are currently extant. Proponents of the various approaches disagree on matters of strategy and detail but one theme is common: we have not received any revelations about the nature of the world -- including our own nature. Whatever knowledge we have has been acquired through a fallible process of conjecture and revision. This common theme will bring to mind the writings of Karl Popper and, in many respects, Popper is the father of contemporary naturalism. Along with (...) Popper, the form of naturalism that I would defend is realistic in the following sense: it considers the acquisition of knowledge of the nature of the world to be a pursuable long-term goal of our epistemic activities. (See Brown [1987, 1988, 1990].) Popper's central interest in truth has led him to object to the pervasive concern with concepts among contemporary philosophers. Truth, Popper insists, is the fundamental epistemic concern; propositions are the bearers of truth; and the evaluation of propositions should be at the center of our epistemic focus (e.g., 1965, pp. 18-21; 1972, pp. 123-24). Concern with concepts, Popper maintains, is a distraction. Yet, this leaves us in an odd position. When we study a particular subject matter, one of our main problems is to determine what kinds of entities and processes occur in that domain. But the kinds of entities and processes we attribute to a domain will be captured in the concepts we use for describing that domain and, from a naturalistic point of view, concepts are no more available through revelation than are propositions. As our knowledge develops, we must not only propose and evaluate propositions, we must also propose and evaluate concepts. (shrink)

Many epistemological problems can be solved by the objective Bayesian view that there are rationality constraints on priors, that is, inductive probabilities. But attempts to work out these constraints have run into such serious problems that many have rejected objective Bayesianism altogether. I argue that the epistemologist should borrow the metaphysician’s concept of naturalness and assign higher priors to more natural hypotheses.

Abstract Criteria of scientific value are of different kinds. This paper concerns ultimate criteria, i.e. the axiology of science. Most ultimate criteria are multi?dimensional. This gives rise to an aggregation problem, which cannot be adequately solved with reference to attitudes and behaviour within the scientific community. Therefore, in many cases, there is no fact of the matter as to whether one theory is better than another. This, in turn, creates problems for methodology.

In this paper I discuss how descriptive studies of science, increasingly emphasised by philosophers of science, can be used to test normative theories of science. I claim that we can use cases of scientific practice as counter examples; if the practice of a given scientist can be shown to be justified and it diverges from the prescriptions of a scientific theory then the theory should be rejected. This approach differs from those offered by previous philosophers of science and at the (...) same time brings the philosophy of science more into line with other areas of philosophy. (shrink)

Scientific claims can be assessed epistemically in either of two ways: according to scientific standards, or by means of philosophical arguments such as the no-miracle argument in favor of scientific realism. This paper investigates the basis of this duality of epistemic assessments. It is claimed that the duality rests on two different notions of epistemic justification that are well-known from the debate on internalism and externalism in general epistemology: a deontological and an alethic notion. By discussing the conditions for the (...) scientific acceptability of empirical results, it is argued that intrascientific justification employs the deontological notion. Philosophical disputes such as those on scientific realism can by contrast be shown to rest on the alethic notion. The implications of these findings both for the nature of the respective epistemic projects and for their interrelation are explored. (shrink)

Relativism in the philosophy of science is widely associated with the work of Thomas Kuhn and Paul Feyerabend. Kuhn and Feyerabend espoused views about conceptual change and variation of scientific method that have apparent relativistic implications. Both held that scientific theories or paradigms may be incommensurable due to semantic variation. Two ways that truth may be relative because of semantic incommensurability will be distinguished. Davidson’s criticism of the idea of an untranslatable language will be discussed, as well as a response (...) to incommensurability based on the causal theory of reference of Kripke and Putnam. A form of relativism with respect to epistemic rationality may also be derived from the claims of Kuhn and Feyerabend about methodological variation. Kuhn’s initial suggestions about paradigm-dependent standards and absence of extra-paradigmatic standards give rise to a view on which rationality is relative to paradigm. Kuhn’s later view that there is a stable set of shared scientific values is less prone to relativistic interpretation. Feyerabend’s claim that “anything goes” suggests an extreme form of relativism, but should be understood instead as the view that all rules of method may be violated in some circumstances. The latter brings Feyerabend’s view into line with Kuhn’s later view. (shrink)

Has the emergence of post-positivism in philosophy of science changed the terms of the “is/ought” dichotomy? If it has demonstrated convincingly that there are no “facts” apart from the theoretical frames and evaluative standards constructing them, can such a cordon sanitaire really be upheld between “facts” and values? The point I wish to stress is that philosophy of science has had a central role in constituting and imposing the fact/value dichotomy and a revolution in the philosophy of science should not (...) leave the dichotomy unaffected. The connection between post-positivism and naturalism will be my guiding thread in considering this “last dogma of positivism.” First this essay will specify the sense of naturalism that it will take to be essential to the post-positivist philosophy of science: the deflation of the notion of the “purity” of scientific knowledge. Then it will turn to the question of the implications that follow for the “autonomy” of ethics, including the danger posed by a new form of scientistic reductionism. (shrink)

Any attempt to evaluate a naturalistic feminist philosophy of cognition and knowledge must acknowledge that there are two distinct core approaches to naturalism (one more radical and well-interpreted by Quine, while the other more moderate and well-interpreted by Goldman). Classical feminist naturalizations of epistemology have drawn inspiration from the Quinean naturalization, they have inherited its defects – the major one: being compelled to renounce doing real epistemology in favor of a merely scientific enterprise.Notwithstanding, the merits of these feminist naturalizations are (...) more than one: they embrace the idea that epistemology needs contributions and help from the sciences, they raise serious doubts about the best science to involve in feminist epistemologies, they contrast (even if implicit) our “local feminist philosophy” (that is, mostly Italian one) not only in its scorn for every science and its technological applications, but also in its conviction that there are essential differences between female/women and male/men about knowledge and cognition.I wish to propose a naturalized feminist epistemology which draws inspiration from the more moderate Goldmanian approach. Much work would be needed in order to combine those feminist approaches which believe in the individualism of the knowing subject with those that are anti–individualist. But, at least, taking inspiration from Goldman and his reliabilism, we may achieve a type of naturalism in feminist epistemologies, in which it would be feasible to understand the reliability of the cognitive faculties of the knowing subject and to understand scientifically whether or not there are differences between female and male faculties – avoiding any essentialist temptations.

I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated. The thesis is confirmed by reference to Neurath's own writings. The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

Naturalism implies unity of method--an application of the methods of science to the methodology of science itself and to value theory. Epistemological naturalists have tried to find a privileged discipline to be the methodological model of philosophy of science and epistemology. However, since science itself is not unitary, the use of one science as a model amounts to a reduction and distorts the philosophy of science just as badly as traditional philosophy of science distorted science, despite the fact that the (...) central theme of naturalized philosophy of science is that methodology should be true to science as practiced. I argue that naturalized philosophy of science must apply a plurality of methods to epistemological issues. (shrink)

In april 1872, with the caisson at a depth of seventy-odd feet and still no bedrock, two men died. The strain for Roebling was nearly unbearable, as his wife later said. On May 18, a third man died, and that same day Roebling made the most difficult and courageous decision of the project. Staking everything — the success of the bridge, his reputation, his career - he ordered a halt. The New York tower, he had concluded, could stand where it (...) was, at a depth of 78 feet 6 inches, not on bedrock, but on “hardpack” sand. From examinations of the strata he had determined to his own satisfaction that no movement had occured at the level since the time of deposit millions of years in the geologic past; so, he said, it was “good enough to found upon”.

Creative approaches in recent work in science studies can be usefully connected with ideas from the pragmatic tradition. This article both criticizes and builds on the contemporary pragmatic views of Hacking, Stich, and others. It selects a theme from the work of James and Dewey as a heuristic for a new, and necessary, pragmatic epistemology of science.

The work of Tversky, Kahneman and others suggests that people often make use of cognitive heuristics such as availability, salience and representativeness in their reasoning and decision making. Through use of a historical example--the recent plate tectonics revolution in geology--I argue that such heuristics play a crucial role in scientific decision making also. I suggest how these heuristics are to be considered, along with noncognitive factors (such as motivation and social structures) when drawing historical and epistemological conclusions. The normative perspective (...) is community-wide, contextual, and instrumental. (shrink)

Some astronomers believe that we have discovered that Pluto is not a planet. I contest this assessment. Recent discoveries of trans-Neptunian Pluto-sized objects do not require that we exclude Pluto from the planets. But the obvious alternative, that classificatory revision is a matter of arbitrary choice, is also unpalatable. I argue that this classificatory controversy — which I compare to the controversy about the classification of the platypus — illustrates how our classificatory practices are laden with normative commitments of a (...) distinctive kind. I argue that the “norm-ladenness” of classification has philosophically significant ramifications for how we think about scientific disputes and debates in the metaphysics of classification such as the monism/pluralism debate.

Unlike more standard non-normative naturalizations of epistemology and philosophy of science, Larry Laudan's naturalized philosophy of science explicitly maintains a normative dimension. This paper critically assesses Laudan's normative naturalism. After summarizing Laudan's position, the paper examines (1) Laudan's construal of methodological rules as 'instrumentalities' connecting methodological means and cognitive ends; (2) Laudan's instrumental conception of scientific rationality; (3) Laudan's naturalistic account of the axiology of science; and (4) the extent to which a normative philosophy of science can be naturalized. It (...) is concluded that Laudan's normative naturalism is as problematic as its non-normative naturalist cousins. (shrink)

In two recent papers, I criticized Ronald N. Giere's and Larry Laudan's arguments for 'naturalizing' the philosophy of science (Siegel 1989, 1990). Both Giere and Laudan replied to my criticisms (Giere 1989, Laudan 1990b). The key issue arising in both interchanges is these naturalists' embrace of instrumental conceptions of rationality, and their concomitant rejection of non-instrumental conceptions of that key normative notion. In this reply I argue that their accounts of science's rationality as exclusively instrumental fail, and consequently that their (...) cases for 'normatively naturalizing' the philosophy of science fail as well.

In this article I argue that a methodological challenge to an integrated history and philosophy of science approach put forth by Ronald Giere almost forty years ago can be met by what I call the Kuhnian mode of History and Philosophy of Science (HPS). Although in the Kuhnian mode of HPS norms about science are motivated by historical facts about scientific practice, the justifiers of the constructed norms are not historical facts. The Kuhnian mode of HPS therefore evades the naturalistic (...) fallacy which Giere’s challenge is a version of. Against the backdrop of a discussion of Laudan’s normative naturalism I argue that the Kuhnian mode of HPS is a superior form of naturalism: it establishes contact to the practice of science without making itself dependent on its contingencies.

Critics of Laudan's normative naturalism have questioned whether methodological rules can be regarded as empirical hypotheses about relations between means and ends. Drawing on Laudan's defense that rules of method are contingent on assumptions about the world, I argue that even if such rules can be shown to be analytic in principle, in practice the warrant for such rules will be empirical. Laudan's naturalism, however, acquires normative force only by construing both methods and epistemic goals as instrumental to practical concerns, (...) and issues only in context-specific and not general methodological principles.

According to the "confrontation model," integrated history and philosophy of science operates like an empirical science. It tests philosophical accounts of science against historical case studies much like other sciences test theory against data. However, the confrontation model's critics object that historical facts can neither support generalizations nor genuinely test philosophical theories. Here I argue that most of the model's defects trace to its usual framing in terms of two problematic accounts of empirical inference: the hypothetico-deductive method and enumerative induction. (...) This framing can be taken to suggest an unprofitable one-off confrontation between particular historical facts and general philosophical theories. I outline more recent accounts of empirical inquiry, which describe an iterative back-and-forth movement between concrete empirical exemplars to their abstract descriptions. Reframed along similar lines, the confrontation model continues to offer both conceptual insight and practical guidance for a naturalized philosophy of science. (shrink)

Today, Larry Laudan is known predominantly for his work on the pessimistic metainduction and for his discussion of science and values. This essay examines a less familiar part of Laudan’s work, his typology of historical methodologies from the late 1970s. My aim is to elucidate Laudan’s typology and to examine one of the types in more depth, namely, the “pragmatic, symbiotic” model of historical methodology. Laudan expounded the model in the essays that eventually became his 1981 book Science and Hypothesis. (...) Laudan himself characterized this approach to methodology as “history of philosophy of science” and described a number of historiographical guidelines for this history. Several of Laudan’s questions about past scientific methodologies are still worth pursuing, although—and in part because—the concept of scientific methodology changed dramatically as philosophers turned to experimentation in the late twentieth century. Moreover, the study of Laudan’s work in the historical context in which it was devised can shed light on the historical turn in philosophy of science. (shrink)

Philosophers use historical case studies to support wide-ranging claims about science. This practice is often criticized as problematic. In this paper we suggest that the function of case studies can be understood and justified by analogy to a well-established practice in biology: the investigation of model organisms. We argue that inferences based on case studies are no more problematic than inferences from model organisms to larger classes of organisms in biology. We demonstrate our view in detail by reference to a (...) case study with a long history: Semmelweis’s discovery of the cause of childbed fever. (shrink)

Ever since Hilary Putnam claimed that a realist philosophy is “the only philosophy that doesn’t make the success of science a miracle,” explanations for the success of science have proliferated in the philosophical literature (Putnam 1975, p. 73). Realists argue that the success of science, as exhibited by our ability to accurately predict and explain a wide range of phenomena, indicates that our theories have identified some of the underlying causal structures of the world (e.g., Boyd 1985, Ellis 1985, McMullin (...) 1984, Salmon 1984). Nonrealists counter that success cannot provide a warrant for belief in the truth of scientific theories because there have been successful theories in the past that are now believed to be false (Laudan 1981b). Instead, they offer a naturalized account whereby our theories are designed to be successful predictors and only those which fulfill this goal survive (Laudan 1987, van Fraassen, 1980). (shrink)

The paper presents a realist account of the epistemic objectivity of science. Epistemic objectivity is distinguished from ontological objectivity and the objectivity of truth. As background, T.S. Kuhn’s idea that scientific theory-choice is based on shared scientific values with a role for both objective and subjective factors is discussed. Kuhn’s values are epistemologically ungrounded, hence provide a minimal sense of objectivity. A robust account of epistemic objectivity on which methodological norms are reliable means of arriving at the truth is presented. (...) The problem remains that deliberative judgement is required to determine the relevance and relative significance of a range of methodological norms. A role is sketched for cognitive virtues which may be exercised in the course of the deliberative judgement. (shrink)

In a recent exchange, John Worrall and Larry Laudan have debated the merits of the model of rational scientific change proposed by Laudan in his book Science and Values. On the model advocated by Laudan, rational change may take place at the level of scientific theory and methodology, as well as at the level of the epistemic aims of science. Moreover, the rationality of a change which occurs at any one of these three levels may be dependent on considerations at (...) the remaining levels. Yet, in spite of the avowedly anti-relativistic motivation of Laudan's model, Worrall criticizes Laudan for irrevocably relativizing scientific rationality to historically variant methodological standards.

This paper is a response to an objection that Markus Seidel has made to my analysis of epistemic relativism. Seidel argues that the epistemic relativist is unable to base a relativist account of justification on the sceptical problem of the criterion in the way that I have suggested in earlier work. In response to Seidel, I distinguish between weak and strong justification, and argue that all the relativist needs is weak justification. In addition, I explain my reasons for employing the (...) idiom of objectivity rather than that of absolutism which Seidel prefers. -/- . (shrink)

How can it be rational to work on a new theory that does not yet meet the standards for good or acceptable theories? If diversity of approaches is a condition for scientific progress, how can a scientific community achieve such progress when each member does what it is rational to do, namely work on the best theory? These two methodological problems, the problem of pursuit and the problem of diversity, can be solved by taking into account the cognitive risk that (...) is involved in theory choice. I compare this solution to other proposals, in particular T. S. Kuhn's and P. Kitcher's view that the two problems demonstrate the epistemic significance of the scientific community. (shrink)

Quine's “Epistemology Naturalized” has become part of the canon in epistemology and excited a widespread revival of interest in naturalism. Yet the status accorded the essay is ironic, since both friends and foes of philosophical naturalism deny that Quine makes a plausible case that the methods of naturalism can accommodate the problems of epistemology.

This review of recent work in the philosophy of science motivated by a commitment to 'naturalism' begins by identifying three key axioms and one theorem shared by philosophers thus self-styled. Owing much to Quine and Ernest Nagel, these philosophers of science share a common agenda with naturalists elsewhere in philosophy. But they have disagreed among themselves about how the axioms and the theorems they share settle long-standing disputes in the philosophy of science. After expounding these disagreements in the work of (...) Boyd, Giere, Laudan, and Kitcher, I argue that naturalism needs to look for more than mere consistency in its foundations. (shrink)

The prescriptive force of methodological rules rests, I argue, on the acceptance of scientific theories; that of the most general methodological rules rests on theories in the philosophy of science, which differ from theories in the several sciences only in generality and abstraction. I illustrate these claims by reference to methodological disputes in social science and among philosophers of science. My conclusions substantiate those of Laudan except that I argue for the existence of transtheoretical goals common to all scientists and (...) concrete enough actually to have bearing on methodology. And I argue that Laudan is committed to such goals himself, willy nilly. (shrink)

For a number of years now, we, as philosophers of science, have been enjoined by more and more of our colleagues to understand the task of developing a philosophy of science to be itself a scientific task. We are told that if we want to understand science we have no better (and perhaps indeed no other) path to such an understanding than the path of science itself. We should view ourselves as ultimately attempting to arrive at a relatively complete theoretical (...) understanding of how science proceeds. This is a call tonaturalizephilosophy of science.Somewhat more recently some philosophers of science have become impatient even with those who have taken up the naturalist banner. It isn’t enough, they tell us, to arrive at an understanding of the nature of philosophy of science that proclaims it to be one science among many. (shrink)

InScience and Values (1984) and other, more recent, works, e.g. (1987a, 1987b, 1989a, 1989b, 1990), Larry Laudan proposes a theory of scientific debate he dubs the reticulated model of scientific rationality (Laudan, 1984, pp. 50–66). The model stands in sharp contrast to hierarchical approaches to rationality exemplified by Popper (1959), Hempel (1965), and Reichenbach (1938), as well as the conventionalist views of rationality defended by Carnap (1950), Popper (1959), Kuhn (1962), and Lakatos (1978). Ironically, the model commits some of the (...) same errors Laudan finds in hierarchicalist and conventionalists approaches to scientific rationality. This paper will show that the model can be fixed by recognizing that criteria of goal assessment have no privileged status. These rules are best viewed as simply rules of rationality (or rules of scientific method) by another name. (shrink)

This discussion adjudicates a dispute between Larry Laudan and Gerald Doppelt over the nature of methodological rules. Laudan holds that all methodological rules are hypothetical imperatives, while Doppelt argues that a subset of those rules, basic methodological standards, are not hypothetical imperatives. I argue that neither writer offers a satisfactory account of methodological rules and that their reliance on the hypothetical/nonhypothetical distinction does not advance our understanding of methodological rules. I propose that we dispense with this dubious distinction and develop (...) an alternative account of scientific norms. (shrink)

Elliott Sober (1987, 1993) and Orzack and Sober (forthcoming) argue that adaptationism is a very general hypothesis that can be tested by testing various particular hypotheses that invoke natural selection to explain the presence of traits in populations of organisms. In this paper, I challenge Sobers claim that adaptationism is an hypothesis and I argue that it is best viewed as a heuristic (or research strategy). Biologists would still have good reasons for employing this research strategy even if it turns (...) out that natural selection is not the most important cause of evolution. (shrink)

Although radical forms of relativism are perhaps beyond the epistemological pale, I argue here that a more moderate form may be plausible, and articulate the conditions under which moderate epistemic relativism could well serve our epistemic goals. In particular, as a result of our limitations as human cognizers, we find ourselves needing to investigate the dappled and difficult world by means of competing communities of highly specialized researchers. We would do well, I argue, to admit of the existence of unresolvable (...) disputes between such communities, but only so long as there is a sufficient amount of fruitful exchange between them as well. I close with some speculation about when it is or is not legitimate to make an “appeal to discipline”: responding to another’s argument by saying something like, “we should do it this way, because we are philosophers (/linguists/psychologists/…), and that’s just what we do”.
