Empirical adequacy, formal explanation and understanding are distinct goals of science. While no a priori criterion for understanding should be laid down, there may be inherent limitations on the way we are able to understand explanations of physical phenomena. I examine several recent contributions to the exercise of fashioning an explanatory discourse to mold the formal explanation provided by quantum mechanics to our modes of understanding. The question is whether we are capable of truly understanding (or comprehending) quantum phenomena, as (...) opposed to simply accepting the formalism and certain irreducible quantum correlations. The central issue is that of understanding versus merely redefining terms to paper over our ignorance. (shrink)

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

Structural realism is considered by many realists and antirealists alike as the most defensible form of scientific realism. There are now many forms of structural realism and an extensive literature about them. There are interesting connections with debates in metaphysics, philosophy of physics and philosophy of mathematics. This entry is intended to be a comprehensive survey of the field.

The debate between scientific realists and anti-realists is now a classic debate in the Philosophy of Science. Van Fraassen (2002) has suggested that the positions that take part in the debate involve not only different doxastic attitudes regarding some propositions, but different epistemic stances, that is, different sets of commitments, values and epistemic strategies. The formulation of this debate in terms of epistemic stances and the voluntarist epistemology it motivates make it plausible to think of it as a deep disagreement. (...) This kind of disagreements cannot be settled by reason alone because they lack the conditions that are necessary for arguments to work. I argue, however, that the attempts to use arguments can have an epistemic value in these contexts, as they can help reveal intuitions. I adopt the view on intuitions put forward by Chudnoff (2014), according to which they are mental states capable of motivating epistemic action. I claim that, while the attempt to utter an argument cannot convince an opponent of changing her mind, it can make her perform some epistemic actions and, thus, bring out some of her intuitions. To show how arguments can work in this way, I take as a study case one of the main realist arguments: the No Miracles Argument. (shrink)

A scientific theory is successful, according to Stanford (2000), because it is suficiently observationally similar to its corresponding true theory. The Ptolemaic theory, for example, is successful because it is sufficiently similar to the Copernican theory at the observational level. The suggestion meets the scientific realists' request to explain the success of science without committing to the (approximate) truth of successful scientific theories. I argue that Stanford's proposal has a conceptual flaw. A conceptually sound explanation, I claim, respects the ontological (...) order between properties. A dependent property is to be explained in terms of its underlying property, not the other way around. The applicability of this point goes well beyond the realm of the debate between scientific realists and antirealists. Any philosophers should keep the point in mind when they attempt to give an explanation of a property in their field whatever it may be. (shrink)

This book examines the philosophical conception of abductive reasoning as developed by Charles S. Peirce, the founder of American pragmatism. It explores the historical and systematic connections of Peirce's original ideas and debates about their interpretations. Abduction is understood in a broad sense which covers the discovery and pursuit of hypotheses and inference to the best explanation. The analysis presents fresh insights into this notion of reasoning, which derives from effects to causes or from surprising observations to explanatory theories. The (...) author outlines some logical and AI approaches to abduction as well as studies various kinds of inverse problems in astronomy, physics, medicine, biology, and human sciences to provide examples of retroductions and abductions. The discussion covers also everyday examples with the implication of this notion in detective stories, one of Peirce’s own favorite themes. The author uses Bayesian probabilities to argue that explanatory abduction is a method of confirmation. He uses his own account of truth approximation to reformulate abduction as inference which leads to the truthlikeness of its conclusion. This allows a powerful abductive defense of scientific realism. This up-to-date survey and defense of the Peircean view of abduction may very well help researchers, students, and philosophers better understand the logic of truth-seeking. (shrink)

Modeling his position on Arthur Fine’s Natural Ontological Attitude, Derek Turner proposed the Natural Historical Attitude. Although these positions share a family resemblance, Turner’s position differs from Fine’s in two important ways. First, Fine’s contextualism is more fine-grained. Second, Turner’s argument for metaphysical agnosticism seems to lead to the implausible conclusion that we should be agnostic about the mind-independence of ordinary objects – a position in tension with Fine’s “core position.” While this paper presents a textual analysis of Fine’s and (...) Turner’s arguments, the conclusions reached here cohere well with some of the best empirically-informed assessments of the historical sciences. Given the diversity of the historical sciences, the fact that many claims in the historical sciences have enough support to be regarded as true, and the implausibility of Turner’s agnosticism, philosophers studying historical science would be better served by embracing a stance closer to Fine’s Natural Ontological Attitude.

This paper develops a phenomenological defense of Ian Hacking's experimental realism about unobservable entities in physical science, employing historically undervalued resources from the phenomenological tradition in order to clarify the warrant for our ontological commitments in science. Building upon the work of Husserl, Merleau-Ponty and Heelan, the paper provides a phenomenological correction of the positivistic conception of perceptual evidence maintained by antirealists such as van Fraassen, the experimental relevance of which is illustrated through a phenomenological interpretation of the 1974 discovery (...) of the J/ ψ particle generally regarded as evidence for the charmed quark. The argument then turns to address known problems in Hacking's account, demonstrating that his own instrumentalist criterion of the real is inadequately rooted in the phenomenology of perception, and as a result, passes over the true ontological significance of experimental phenomena. The paper maintains that the proper criterion, only indirectly related to instrumentality, is the distinctive style of the real encountered in perception: empirical pregnancy. With this notion and Merleau-Ponty's associated reversibility thesis, I show that the phenomenological tradition provides insights into the warrant for our realist commitments that have yet to be adequately acknowledged by philosophers of science.

Scientific realists contend that theory-conjunction presents a problem for empiricist conceptions of scientific knowledge and practice. Van Fraassen (1980) has offered a competing account of theory-conjunction which I argue fails to capture the mercenary character of epistemic dependence in science. Representative cases of theory-conjunction developed in the present paper show that mercenary reliance implies a "principle of epistemic symmetry" which only a realist can consistently accommodate. Finally, because the practice in question involves the conjunction of theories, a version of realism (...) more robust than the "entity realism" of Cartwright (1983, 1989) and Hacking (1983) is required to explain the success of theory-conjunction.

Ludwik Fleck’s Genesis and Development of a Scientific Fact is an extended argument for the inclusion of social factors in the history and philosophy of science. Fleck uses the history of syphilis as his case study, which falls into two parts. In the first two chapters of his book, Fleck presents a history of the change of the concept of syphilis as a “carnal scourge with strong moralistic connotations” in the middle ages to the modern concept of syphilis as an (...) infectious disease (1979, 77). In the second part of the book, he presents a detailed account of the development of a serum test for syphilis, the Wasserman reaction. Fleck also argues that perception is theory-laden, for example, in his comparative study of anatomical drawings, and for the importance of social pressures on the development of science, for example, in his discussion of the rivalry between nations to first develop a cure for syphilis, as demanded by politicians (1979, 133 ff. and 68).

Poincare’s arguments for his thesis of the conventionality of metric depend on a relationalist program for dynamics, not on any general philosophical interpretation of science. I will sketch Poincare’s development of the relationalist program and show that his arguments for the conventionality of metric do not depend on any global strategies such as a general empiricism or Duhemian underdetermination arguments. Poincare’s theory of space, while empirically false, is more philosophically sophisticated than his critics have claimed.

I develop an account of predictive similarity that allows even Antirealists who accept a correspondence conception of truth to answer the Realist demand (recently given sophisticated reformulations by Musgrave and Leplin) to explain the success of particular scientific theories by appeal to some intrinsic feature of those theories (notwithstanding the failure of past efforts by van Fraassen, Fine, and Laudan). I conclude by arguing that we have no reason to find truth a better (i.e., more plausible) explanation of a theory's (...) success than predictive similarity, even of its success in making novel predictions.

“Scientific theories are maps of the natural world.” This metaphor is often used as part of a deflationary argument for a weak but relatively global version of scientific realism, a version that recognizes the place of conventions, goals, and contingencies in scientific representations, while maintaining that they are typically true in a clear and literal sense. By examining, in a naturalistic way, some relationships between maps and what they map, we question the scope and value of realist construals of maps—and (...) by extension of scientific representations. Deflationary philosophy of science requires more variegated stances. (shrink)

In this paper I argue that the explanationist argument in favour of moral realism fails. According to this argument, the ability of putative moral properties to feature in good explanations provides strong evidence for, or entails, the metaphysical claims of moral realism. Some have rejected this argument by denying that moral explanations are ever good explanations. My criticism is different. I argue that even if we accept that moral explanations are (sometimes) good explanations the metaphysical claims of realism do not (...) follow. (shrink)

Arthur Fine presented the Natural Ontological Attitude as a third alternative between scientific realism and anti-realism by identifying a core position contained in both and rejecting any philosophical addition to this core. At first, Fine’s proposal was understood as offering a doxastic middle ground between believing in the truth of a theory and believing in its empirical adequacy. In this reading, NOA was widely disregarded after Alan Musgrave’s criticisms of it, which characterized Fine’s proposal as a form of realism. After (...) that, NOA was reinterpreted as a local variety of realism focused in changing the attitude used to settle the scientific realism debate, by rejecting global philosophies with an approach external to science, and by considering only the scientific evidence with a contextualist mood. Although this reading clarifies how to understand NOA, there is still no consensus about what is Fine’s argument to support it. I organize the four main interpretations of Fine’s defense and point their main flaws. Finally, I develop some clarifications about NOA in order to solve the flaws of the preceding interpretations, defending that NOA is based upon a prevalence of the epistemic values actually used in scientific practice.

There has been a great deal of skepticism towards the value of the realism/anti-realism debate. More specifically, many have argued that plausible formulations of realism and anti-realism do not differ substantially in any way. In this paper, I argue against this trend by demonstrating how a hypothetical resolution of the debate, through deeper engagement with the historical record, has important implications for our criterion of theory pursuit and science policy. I do this by revisiting Arthur Fine’s ‘small handful’ argument for (...) realism and show how the debate centers on whether continuity should be an indicator for the future fruitfulness of a theory. I then demonstrate how these debates work in practice by considering the case of the Human Brain Project. I close by considering some potential practical considerations of formulating meta-inductions. By doing this, I contribute three insights to the current debate: 1) demonstrate how the realism/anti-realism debate is a substantive debate, 2) connect debates about realism/anti-realism to debates about theory choice and pursuit, and 3) show the practical significance of meta-inductions.

Quine’s thesis of underdetermination is significantly weaker than it has been taken to be in the recent literature, for the following reasons: (i) it does not hold for all theories, but only for some global theories, (ii) it does not require the existence of empirically equivalent yet logically incompatible theories, (iii) it does not rule out the possibility that all perceived rivalry between empirically equivalent theories might be merely apparent and eliminable through translation, (iv) it is not a fundamental thesis (...) within Quine’s philosophy, and (v) it does not carry with it the anti-realistic consequences often associated with the thesis in recent debates. The paper analyzes Quine’s views on the matter and the changes they underwent over the years. A conjecture is put forth about why Quine’s thesis has been so widely misrepresented: Quine’s writings up to 1975 tackled primarily the formulation and justification of the thesis, but afterwards were concerned mostly with the question whether empirically equivalent rivals to the theory we hold are to be considered true also. When this latter discussion is read without bearing in mind Quine’s earlier formulation and justification of the thesis, his thesis seems to have stronger epistemic consequences than it actually does. A careful reading of his later writings shows, however, that the formulation of the thesis remained unchanged after 1975, and that his mature and considered views supported only a very mitigated version of the thesis.

If the defenders of typical postmodern accounts of science (and their less extreme social-constructivist partners) are at one end of the scale in current philosophy of science, who shall we place at the other end? Old-style metaphysical realists? Neo-neo-positivists? ... Are the choices concerning realist issues as simple as being centered around either, on the one hand, whether it is the way reality is “constructed” in accordance with some contingent language game that determines scientific “truth”; or, on the other hand, (...) whether it is the way things are in an independent reality that makes our theories true or false? If, in terms of realism, “strong” implies “metaphysical” in the traditional sense, and “weak” implies “non-absolutist” or “non-unique”, what – if anything – could realism after Rorty's shattering of the mirror of nature still entail? In accordance with my position as a model-theoretic realist, I shall show in this article the relevance of the assumption of an independent reality for postmodern (philosophy of) science – against Lyotard's dismissal of the necessity of this assumption for science which he interprets as a non-privileged game among many others. I shall imply that science is neither the “child” of positivist philosophy who has outgrown her mother, freeing herself from metaphysics and epistemology, nor is science, at the other end of the scale, foundationless and up for grabs.

Taking Arthur Fine’s The Shaky Game as my inspiration, and the recent 25th anniversary of the publication of that work as the occasion to exercise that inspiration, I sketch an alternative to the “Naturalism” prevalent among philosophers of physics. Naturalism is a methodology eventuating in a metaphysics. The methodology is to seek the deep framework assumptions that make the best sense of science; the metaphysics is furnished by those assumptions and supported by their own support of science. The alternative presented (...) here, which I call “Locavoracity,” shares Naturalism’s commitment to making sense of science, but alters Naturalism’s methodology. The Locavore’s sense-making projects are piecemeal, rather than sweeping. The Locavore’s hypothesis is that the collection of local sense-making projects fails to issue a single overarching unifying framework deserving of the title “the metaphysics that makes the best sense of science.” I muster some examples supporting the Locavore hypothesis from the interpretation of quantum field theories. (shrink)

Naturalism in the philosophy of science has proceeded differently than the familiar forms of meta-philosophical naturalism in other sub-fields, taking its cues from “science as we know it” (Cartwright in The Dappled World, Oxford University Press, Oxford, 1999, p. 1) rather than from a philosophical conception of “the Scientific Image.” Its primary focus is scientific practice, and its philosophical analyses are complementary and accountable to empirical studies of scientific work. I argue that naturalistic philosophy of science is nevertheless criterial for (...) other versions of meta-philosophical naturalism; relying on a conflicting conception of scientific understanding would constitute a “first philosophy” imposed on the sciences. Moreover, naturalistic philosophy of science provides the basis for a “radically” naturalistic alternative to the familiar forms of orthodox or liberal naturalism. Goodman, Sellars and Hempel had previously challenged empiricist scruples against causal connections or nomological necessity by arguing that scientific concepts already had modal import. The radical naturalism I defend similarly challenges meta-philosophical naturalists’ conception of the Scientific Image as anormative, and instead shows how the normativity of scientific understanding in practice is a scientifically intelligible natural phenomenon. This account then provides a basis for naturalistic reflection on how other practices and normative concerns fit together with the best scientific understanding of human ways of life. (shrink)

Modernism in the philosophy of science demands a unified story about what makes an inquiry scientific (or a successful science). Fine's "natural ontological attitude" (NOA) is "postmodern" in joining trust in local scientific practice with suspicion toward any global interpretation of science to legitimate or undercut that trust. I consider four readings of this combination of trust and suspicion and their consequences for the autonomy and cultural credibility of the sciences. Three readings take respectively Fine's trusting attitude, his emphasis upon (...) local practice, and his antiessentialism about science as most fundamental to NOA. A fourth, more adequate reading, prompted by recent feminist interpretations of science, offers less restrictive readings of both Fine's trust and his suspicion toward approaching science with "ready-made philosophical engines" (Fine 1986b, 177).

This survey of major developments in North American philosophy of science begins with the mid-1960s consolidation of the disciplinary synthesis of internalist history and philosophy of science (HPS) as a response to criticisms of logical empiricism. These developments are grouped for discussion under the following headings: historical metamethodologies, scientific realisms, philosophies of the special sciences, revivals of empiricism, cognitivist naturalisms, social epistemologies, feminist theories of science, studies of experiment and the disunity of science, and studies of science as practice and (...) culture. A unifying theme of the survey is the relation between historical metamethodologists and scientific realists, which dominated philosophical work in the late 1970s. I argue that many of the alternative cognitive naturalisms, social epistemologies, and feminist theories that have been proposed can be understood as analogues to the differences between metamethodological theories of scientific rationality and realist accounts of successful reference to real causal processes. Recent work on experiment, scientific practice, and the culture of science may, however, challenge the underlying conception of the field according to which realism and historical rationalism (or their descendants) are the important alternatives available, and thus may take philosophy of science in new directions.

This paper recapitulates my four primary lines of argument that what is wrong with scientific realism is not realist answers to questions to which various anti-realists give different answers, but instead assumptions shared by realists and anti-realists in framing the question. Each strategy incorporates its predecessors as a consequence. A first, minimalist challenge, taken over from Arthur Fine and Michael Williams, rejects the assumption that the sciences have a general aim or goal. A second consideration is that realists and antirealists (...) undertake a mistaken, substantive commitment to a separation between mind and world, which allows them to frame the issue in terms of how epistemic “access” to the world is mediated. A third strategy for dissolving the realism question challenges its underlying commitment to the independence of meaning and truth, a strategy pursued in different ways by Donald Davidson, Robert Brandom, John McDowell, John Haugeland, and myself. The fourth and most encompassing strategy shows that realists and antirealists are thereby committed to an objectionably antinaturalist conception of scientific understanding, in conflict with what the sciences themselves have to say about our own conceptual capacities.

In several recent papers, Arthur Fine has developed a far-reaching attack upon both the standard realist interpretations of science and their most prominent anti-realist alternatives (1986a, 1986b, 1986c). In their place, Fine proposes not another position on the realist/anti-realist axis, but an attitude toward science, the “natural ontological attitude” (NOA), which is supposed to remove any felt need for a philosophical interpretation of science.In this paper I will be concerned with Fine’s reasons for adopting NOA rather than his arguments against (...) realism and anti-realism. Unless these reasons are adequate, Fine’s papers are likely to set off a scramble for new and better arguments concerning realism, rather than the reorientation of the philosophy of science which his polemics are clearly intended to provoke. Thus for my purposes, we can presume that Fine’s criticisms of standard positions are generally sound. The question is whether Fine’s proposed alternative attitude can then satisfy the same argumentative standards. (shrink)

My target is the epistemological dimension of the realism debate. After establishing a stance voluntarist framework with a Jamesian background, drawing mostly on Wylie, Chakravarty, and van Fraassen, I argue that current voluntarists are too permissive. I show that especially various anti-realist stances but also some realist and selective realist stances block themselves from refutation by the history of science. I argue that such stances should be rejected. Finally, I propose that any disagreement that cannot be resolved by this strategy (...) frequently boils down to an epistemic value disagreement about balancing the truth-goal. (shrink)

In order to reconnect Quine's views to the current debate on scientific realism, I reframe Quine's scientific realism into a semantic, a metaphysical, and an epistemological dimension. With this conceptual background, I review the historical development of Quine's scientific realism from the late 1940s until his death in 2000. I challenge Soames's view that Quine is a phenomenalist at the time of “Two Dogmas of Empiricism” (1951) and show that he remains agnostic between a realist and an anti‐realist conceptual scheme (...) instead. I also argue that Quine's early views on regimentation are incompatible with a strong formulation of semantic realism. I proceed in reconstructing how he becomes a metaphysical and epistemological realist in the mid‐1950s and argue against the view of Keskinen and Fogelin that interprets Quine as being a metaphysical anti‐realist. Contrary to Davidson, I defend the view that he never gave up normative epistemology and really is a proper epistemological realist. Finally, I discuss how he tries to reconcile his realism with his thesis of ontological relativity and how this necessitates the switch to a stronger form of semantic realism. (shrink)

It is argued that Arthur Fine's “natural ontological attitude” (NOA), i.e., the view that science should not be philosophically (either realistically or anti‐realistically) interpreted at all but should rather be allowed to “speak for itself”, is seriously problematic, even though it contains deep insights which philosophers of science should take into account. In particular, Fine succeeds in showing that no non‐question‐begging, conclusive demonstration of scientific realism (e.g., on “explanationist” grounds) is possible. But this is not a threat to scientific realism, (...) if realism is subordinated to pragmatism. From the pragmatic point of view, the demand for a non‐circular proof of scientific realism is mistaken. Rather, realism can be seen as our natural attitude, based on our practices, scientific and otherwise. Fine's NOA turns out to be, on a charitable reading, quite close to a version of pragmatic realism. The paper concludes by briefly examining the idea of regarding realism as a “narrative explanation” of science. (shrink)

The pessimistic induction over scientific theories holds that present theories will be overthrown as were past theories. The pessimistic induction over scientists holds that present scientists cannot conceive of future theories just as past scientists could not conceive of present theories. The pessimistic induction over realists :4321–4330, 2013) holds that present realists are wrong about present theories just as past realists were wrong about past theories. The pessimistic induction over antirealist theories :3–21, 2014) holds that the latest antirealist explanation of (...) the success of science :891–901, 2003) has hidden problems just as its eight predecessors did. In this paper, I criticize the pessimistic inductions over scientific theories, scientists, and realists, introduce a pessimistic induction over antirealist theories, and then construct two new pessimistic inductions. One is a pessimistic induction over antirealists according to which the author of the latest antirealist proposal cannot see hidden problems with his proposal just as his antirealist predecessors could not see hidden problems with their proposals. The other is the pessimistic induction over pessimists according to which since past pessimists have been wrong about their present scientific theories from the early twentieth century to the early twenty-first century, future pessimists will also be wrong about their present scientific theories from the early twenty-first century to the early twenty-second century.

Realism and surrealism claim, respectively, that a scientific theory is successful because it is true, and because the world operates as if it is true. Lyons :891–901, 2003) criticizes realism and argues that surrealism is superior to realism. I reply that Lyons’s criticisms against realism fail. I also attempt to establish the following two claims: Realism and surrealism lead to a useful prescription and a useless prescription, respectively, on how to make an unsuccessful theory successful. Realism and surrealism give the (...) credit for the success of a theory to an appropriate factor and to an inappropriate factor, respectively. Finally, I point out that surrealism is vulnerable to my pessimistic induction :3–21, 2014a) against antirealism. (shrink)

This paper canvasses the various dimensions along which theories of truth may disagree about the extent to which truth is minimal.

Scientific realists use the “no miracle argument” to show that the empirical and pragmatic success of science is an indicator of the ability of scientific theories to give true or truthlike representations of unobservable reality. While antirealists define scientific progress in terms of empirical success or practical problem-solving, realists characterize progress by using some truth-related criteria. This paper defends the definition of scientific progress as increasing truthlikeness or verisimilitude. Antirealists have tried to rebut realism with the “pessimistic metainduction”, but critical (...) realists turn this argument into an optimistic view about progressive science. (shrink)

While most philosophers of science agree that science is, perhaps in many ways, a highly successful enterprise, there is no consensus about the best way of defining and measuring this success. Philosophers are also divided in their views about two further issues: What does the success of a scientific theory indicate? What is the best way of explaining this success?After some remarks about institutional and pragmatic measures of success, this paper concentrates on rival ways of defining cognitive success. Four realist (...) measures of epistemic credit are discussed: probability, confirmation (corroboration), expected verisimilitude, and probable verisimilitude. Laudan’s non-realist concept of the problem-solving effectiveness of a theory is compared to Hempel’s notion of systematic power. I argue that such truth-independent concepts alone are insufficient to characterize scientific advance. But if they are used as truth-dependent epistemic utilities, they serve as fallible indicators of the truth or truthlikeness of a theory. (shrink)

SummaryEllis, Jardine and Putnam have argued that the would‐be scientific realist can only avoid being a metaphysical realist by becoming an “internal realist” . While metaphysical realism is unattractive, the approaches to truth offered by Ellis, Jardine and Putnam are quite unacceptable. However, the is no reason to think that one who wishes to be a scientific realist is limited to these two options.

The No-Miracles Argument (NMA) is often used to support scientific realism. We can formulate this argument as an inference to the best explanation this accusation of circularity by appealing to reliabilism, an externalist epistemology. In this paper I argue that this retreat fails. Reliabilism suffers from a potentially devastating difficulty known as the Generality Problem and attempts to solve this problem require adopting both epistemic and metaphysical assumptions regarding local scientific theories. Although the externalist can happily adopt the former, if (...) he adopts the latter then the Generality Problem arises again, but now at the level of scientific methodology. Answering this new version of the Generality Problem is impossible for the scientific realist without making the important further assumption that there exists the possibility of a unique rule of Doing this however would make the NMA viciously premise circular.

In this paper, I argue that the ultimate argument for Scientific Realism, also known as the No-Miracles Argument (NMA), ultimately fails as an abductive defence of Epistemic Scientific Realism (ESR), where (ESR) is the thesis that successful theories of mature sciences are approximately true. The NMA is supposed to be an Inference to the Best Explanation (IBE) that purports to explain the success of science. However, the explanation offered as the best explanation for success, namely (ESR), fails to yield independently (...) testable predictions that alternative explanations for success do not yield. If this is correct, then there seems to be no good reason to prefer (ESR) over alternative explanations for success. (shrink)

The concern of this paper is not with the truth of any particular realist or anti-realist view, but rather with determining what it is to be a realist or anti-realist in the first place. While much skepticism has been voiced in recent years about the viability of such a project, my goal is to articulate interesting and informative conditions whereby any view in any domain of experience can count as either a realist or an anti-realist position.

Abstract It is sometimes thought that Absolute Idealism was undermined by its inability to deal with science. Through a critical discussion of F. H. Bradley's philosophy of science, this idea is challenged. His views on science are divided into a positive and a negative part, and it is argued that, although he found the scientific world view to be essentially false, he was nonetheless able to develop a sympathetic and intelligent philosophy of science. This was basically pragmatic and instrumental in (...) tone, and gave to science a large measure of autonomy from philosophy. His doctrine is connected with certain contemporary ideas in the philosophy of science. (shrink)

In developing an "internal" sociology of science, the sociology of scientific knowledge drew on Wittgenstein’s later philosophy to reinterpret traditional epistemological topics in sociological terms. By construing scientific reasoning as rule following within a collective, sociologists David Bloor and Harry Collins effectively blocked outside criticism of a scientific field, whether scientific, philosophical, or political. Ethnomethodologist Michael Lynch developed an alternative, Wittgensteinian reading that similarly blocked philosophical or political critique, while also disallowing analytical appeals to historical or institutional contexts. I criticize (...) these Wittgensteinian sociologies and argue for the historical and contemporary significance of methodological criticisms of scientific practice that conjoin epistemological and political categories. I consider two such cases briefly: the Baconian criticism of Scholastic science in the early Royal Society and the criticism of AIDS drug testing protocols by activists. Key Words: Wittgenstein • sociology of scientific knowledge • ethnomethodology • scientific method • interpretive sociology. (shrink)

Climate change assessments rely upon scenarios of socioeconomic developments to conceptualize alternative outcomes for global greenhouse gas emissions. These are used in conjunction with climate models to make projections of future climate. Specifically, the estimations of greenhouse gas emissions based on socioeconomic scenarios constrain climate models in their outcomes of temperatures, precipitation, etc. Traditionally, the fundamental logic of the socioeconomic scenarios—that is, the logic that makes them plausible—is developed and prioritized using methods that are very subjective. This introduces a fundamental (...) challenge for climate change assessment: The veracity of projections of future climate currently rests on subjective ground. We elaborate on these subjective aspects of scenarios in climate change research. We then consider an alternative method for developing scenarios, a systems dynamics approach called ‘Cross-Impact Balance’ (CIB) analysis. We discuss notions of ‘objective’ and ‘objectivity’ as criteria for distinguishing appropriate scenario methods for climate change research. We distinguish seven distinct meanings of ‘objective,’ and demonstrate that CIB analysis is more objective than traditional subjective approaches. However, we also consider criticisms concerning which of the seven meanings of ‘objective’ are appropriate for scenario work. Finally, we arrive at conclusions regarding which meanings of ‘objective’ and ‘objectivity’ are relevant for climate change research. Because scientific assessments uncover knowledge relevant to the responses of a real, independently existing climate system, this requires scenario methodologies employed in such studies to also uphold the seven meanings of ‘objective’ and ‘objectivity.’.

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)

Both sides in the debate about scientific realism have argued that their view provides a better account of actual scientific practice. For example, it has been claimed that the practice of theory conjunction presupposes realism, and that scientists' use of multiple and incompatible models presupposes some form of instrumentalism. Assuming that the practices of science are rational, these conclusions cannot both be right. I argue that neither of them is right, and that, in fact, all scientific practices are compatible with (...) both realism and instrumentalism. I also repudiate van Fraassen's argument to the effect that the instrumentalist account of scientific practice is logically weaker, hence better, than the realist account. In the end, there are no scientific practice arguments on the table that support either side of the debate. It is also noted that the deficiencies of van Fraassen's argument are recapitulated in Putnam's miracle argument for realism. My pessimistic assessment of the state of the debate is reminiscent of Arthur Fine's. However, Fine's argument for the ‘natural ontological attitude’ once again repeats the problems of van Fraassen's and Putnam's arguments. (shrink)

The antirealist argument from the underdetermination of theories by data relies on the premise that the empirical content of a theory is the only determinant of its belief-worthiness (premise NN). Several authors have claimed that the antirealist cannot endorse NN, on pain of internal inconsistency. I concede this point. Nevertheless, this refutation of the underdetermination argument fails because there are weaker substitutes for NN that will serve just as well as a premise to the argument. On the other hand, antirealists (...) have not made a convincing casefor NN (or its weaker substitutes) either. In particular, I criticize van Fraassen's recent claim that all ampliative rules in epistemology must be rejected on the grounds that they lead to incoherence. The status of the underdetermination argument remains unsettled. (shrink)

Scientific realists have argued that the truth(likeness) of our theories provides the only explanation for the success of science. I consider alternative explanations proposed by antirealists. I endorse Leplin's contention that neither van Fraassen's Darwinist explanation nor Laudan's methodological explanation provides the sort of explanatory alternative which is called for in this debate. Fine's suggestion--that the empirical adequacy of our theories already explains their success--is more promising for antirealists. Leplin claims that this putative explanation collapses into realism on one reading (...) and into vacuity on another reading. But his analysis conflates three doctrines into two, and one of the three avoids both realism and vacuity. (shrink)

The central motivation behind the scientific realism debate is explaining the impressive success of scientific theories. The debate has been dominated by two rival types of explanations: the first relies on some sort of static, referentially transparent relationship between the theory and the unobservable world, such as truthlikeness, representation, or structural similarity; the second relies on no robust relationship between the theory and unobservable reality at all, and instead draws on predictive similarity and the stringent methodology of science to explain (...) success. I argue that this is a false dichotomy, at least insofar as dynamical theories are concerned. The best explanation of the success of dynamical theories, I argue, must appeal to a robust but referentially opaque theory–world relation. The dynamical notion of ‘tracking’ fulfills this promise. I formulate a modified no miracles argument that is liberated from the false dichotomy and show how tracking responds to the modified argument. (shrink)
