Based on archival material from the Carnap and FeiglArchives, this paper re-examines Carnap's approach tothe issue of scientific realism in the 1950s and theearly 1960s. It focuses on Carnap's re-invention ofthe Ramsey-sentence approach to scientific theoriesand argues that Carnap wanted to entertain a genuineneutral stance in the realism-instrumentalism debate.Following Grover Maxwell, it claims that Carnap'sposition may be best understood as a version of`structural realism'. However, thus understood,Carnap's position faces the challenge that Newmanraised against Russell's structuralism: the claim thatthe knowledge of (...) the unobservable is limited to itspurely structural characteristics is eitheruninformative or unsustainable.

This reassessment of the long debate about Friedman's thesis on the pointlessness of testing assumptions in economics shows that Friedman's three famous examples, on which a large part of the credit given to this thesis is based, far from substantiating it, can be used to establish radically opposite conclusions. Furthermore, it is shown that this so-called “instrumentalist” thesis, when applied by Friedman to economics, is of a quite different nature and raises much more serious problems than the standard instrumentalist thesis (...) devised by some methodologists of physics. To disentangle these ambiguities concerning realism and instrumentalism applied to physics or to economics, this paper refers to Van Fraassen's “constructive empiricism”, which is helpful in reformulating, in a more satisfactory way, the essentials of Friedman's considerations about empiricism and anti-realism.

In his article “Choosing the Realist Framework” (2011), Stathis Psillos develops an empirical realism; a scientific realism that should be acceptable even to empiricists with metaphysical anxieties. This sounds promising in a time of increased interest in deflationary (neo-Carnapian) approaches to metaphysics. Psillos proposes to regard scientific realism as an ontic framework, i.e. as an answer to the question what it is to be real and not what is real. Adopting the realist framework, the realist ontology follows. While the adoption (...) of an ontic framework is an unforced choice, Psillos argues that one must adopt the realist framework, if one aims for a causally and nomologically coherent image of the world. -/- I argue, on the one hand, that if empirical realism introduces a term ‘real’ that only applies to unobservables, then observables and unobservables are equally real only because the same signifier, ‘real’, is used for two different concepts. On the other hand, insisting that nothing is given prior to the realist framework is in close proximity to idealism. An empirical realist must insist that only some unqualified empirical input is given. However, without a pre-framework ontology, the aim of a causally and nomologically coherent image of the world cannot be conducive to the correct ontology. I propose that this leaves the aim obsolete and thereby empirical realism undefended. I conclude that while the realist framework does reproduce an ontology that resembles the realist ontology, it is questionable whether scientific realists or metaphysical deflationists will find the position attractive.

The concept of a linguistic framework and the distinction between internal and external questions are the central ideas of Rudolf Carnap's "Empiricism, Semantics, and Ontology." It is not uncommon to encounter the suggestion that reflection on the theoretical and experimental investigations which led to the acceptance of the atomic hypothesis undermines Carnap's distinction between these two types of question and the utility of his notion of a linguistic framework. I believe this is a mistake. There is a natural development of (...) the distinction and the notion of framework choice with which it is paired that is perfectly capable of accommodating this case. I show this by bringing out a subtlety that arises in the extension of the con ceptual apparatus of ESO to the realism/instrumentalism controversy. When this subtlety is taken into account, the question contested by the nineteenth- and early twentieth-century opponents and proponents of the atomic hypothesis, and successfully addressed by Einstein and Perrin, is readily seen to be internal. Moreover, this formulation of the distinction and the controversy are both independent of Carnap's views on cognitive significance and factual content. I conclude with a presentation and discussion of two formulations of the realism/instrumentalism controversy that are based on Carnap's explication of the factual content of a theory in terms of the notion of its Ramsey sentence.

This chapter contains sections titled: Pragmatism's Reputed Place in the Empiricist Tradition Peirce's Naturalist Account of Truth Pragmatism and Minimalism Experience: Physical, Mathematical, Metaphysical, and Moral.

Logical empiricism is commonly seen as a counter-position to scientific realism. In the present paper it is shown that there indeed existed a realist faction within the logical empiricist movement. In particular, I shall point out that at least four types of realistic arguments can be distinguished within this faction: Reichenbach’s ‘probabilistic argument,’ Feigl’s ‘pragmatic argument,’ Hempel’s ‘indispensability argument,’ and Kaila’s ‘invariantist argument.’ All these variations of arguments are intended to prevent the logical empiricist agenda from the shortcomings of radical (...) positivism, instrumentalism, and other forms of scientific antirealism. On the whole, it will be seen that logical empiricism and scientific realism are essentially compatible with each other. Especially Kaila’s invariantist approach to science (and nature) comes quite close to what nowadays is discussed under the label ‘structural realism.’ This, in turn, necessitates a fundamental reevaluation of Kaila’s role in the logical empiricist movement in particular and in twentieth-century philosophy of science in general.

Elliott Sober is both an empiricist and an instrumentalist. His empiricism rests on a principle called actualism, whereas his instrumentalism violates this. This violation generates a tension in his work. We argue that Sober is committed to a conflicting methodological imperative because of this tension. Our argument illuminates the contemporary debate between realism and empiricism which is increasingly focused on the application of scientific inference to testing scientific theories. Sober’s position illustrates how the principle of actualism drives a wedge between (...) two conceptions of scientific inference and at the same time brings to the surface a deep conflict between empiricism and instrumentalism.

Depending on the realist or instrumentalist twist that is given to positivism, interesting arguments can be made for both causal and classical theories of reference with regard to the use of scientific terms in the language of theory. But my claim is that the rigid foundationalism that supports the theoretical terms via the correspondence rules of the Received View undercuts the notion that it is possible to argue coherently for a causal theory of reference as allied to a positivistic view.

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ explains that the history (...) of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

The thought that there is a way to reconcile empiricism with a realist stance towards scientific theories, avoiding instrumentalism and without fearing that this will lead straight to metaphysics, seems very promising. This paper aims to articulate this thought. It consists of two parts. The first (sections 2 and 3) will articulate how empiricism can go for scientific realism without metaphysical anxiety. It will draw on the work of Moritz Schlick, Hans Reichenbach and Herbert Feigl to develop an indispensability argument (...) for the adoption of the realist framework. This argument, unlike current realist arguments, has a pragmatic ring to it: there is no ultimate argument for the adoption of the realist framework. The guiding thought here is that fundamental ontic questions are not dealt with in the same way in which questions about the reality of ordinary entities (be they stones or electrons) are dealt with—the ontic framework must already be in place before questions about the reality of specific entities are raised. The second part (sections 4 and 5) will articulate reasons for avoiding instrumentalism. Most space is given in offering reasons to refrain from adopting P. Kyle Stanford’s (2006) neo-instrumentalism—a very sophisticated version of instrumentalism that seems to work within the realist framework and promises empiricists a way to avoid scientific realism. Scientific realism is alive and well because of Ti(a)na: there is (almost) no alternative. However, in section 6, it will be argued that there is room for rapprochement between contextualist instrumentalism and scientific realism. The paper is accompanied by an appendix in which Reichenbach’s argument for scientific realism is presented and discussed. (shrink)

Surprisingly enough, modified versions of the confirmation theory of Carnap and Hempel and the truth approximation theory of Popper turn out to be smoothly synthesizable. The glue between confirmation and truth approximation appears to be the instrumentalist methodology, rather than the falsificationist one.By evaluating theories separately and comparatively in terms of their successes and problems (hence even if they are already falsified), the instrumentalist methodology provides – both in theory and in practice – the straight route for short-term empirical progress (...) in science in the spirit of Laudan. However, it is argued that such progress is also functional for all kinds of truth approximation: observational, referential, and theoretical. This sheds new light on the long-term dynamic of science and hence on the relation between the main epistemological positions, viz., instrumentalism (Toulmin, Laudan), constructive empiricism (van Fraassen), referential realism (Hacking and Cartwright), and theory realism of a non-essentialist nature (Popper), here called constructive realism.In From Instrumentalism to Constructive Realism (2000) the above story is presented in great detail. The present synopsis highlights the main ways of theory evaluation presented in that book, viz. evaluation in terms of confirmation (or falsification), empirical progress and truth approximation.

The logical empiricists said some good things about epistemology and scientific method. However, they associated those epistemological ideas with some rather less good ideas about philosophy of language. There is something epistemologically suspect about statements that cannot be tested. But to say that those statements are meaningless is to go too far. And there is something impossible about trying to figure out which of two empirically equivalent theories is true. But to say that those theories are synonymous is also to (...) go too far. My goal in this paper is not to resuscitate all these positivist ideas, but to revisit just one of them. Instrumentalism is the idea that theories are instruments for making predictions. Of course, no one would disagree that this is one of the things we use theories to do. In just the same way, no one could disagree with the emotivist claim that one of the things we do with ethical terms like "good" and "right" is to express our feelings of approval and disapproval. Instrumentalism and emotivism become contentious, and therefore interesting, when these claims are supplemented. (shrink)

Roughly, instrumentalism is the view that science is primarily, and should primarily be, an instrument for furthering our practical ends. It has fallen out of favour because historically influential variants of the view, such as logical positivism, suffered from serious defects. -/- In this book, however, Darrell P. Rowbottom develops a new form of instrumentalism, which is more sophisticated and resilient than its predecessors. This position—‘cognitive instrumentalism’—involves three core theses. First, science makes theoretical progress primarily when it furnishes us with (...) more predictive power or understanding concerning observable things. Second, scientific discourse concerning unobservable things should only be taken literally in so far as it involves observable properties or analogies with observable things. Third, scientific claims about unobservable things are probably neither approximately true nor liable to change in such a way as to increase in truthlikeness. -/- There are examples from science throughout the book, and Rowbottom demonstrates at length how cognitive instrumentalism fits with the development of late nineteenth- and early twentieth-century chemistry and physics, and especially atomic theory. Drawing upon this history, Rowbottom also argues that there is a kind of understanding, empirical understanding, which we can achieve without having true, or even approximately true, representations of unobservable things. In closing the book, he sets forth his view on how the distinction between the observable and unobservable may be drawn, and compares cognitive instrumentalism with key contemporary alternatives such as structural realism, constructive empiricism, and semirealism. -/- Overall, this book offers a strong defence of instrumentalism that will be of interest to scholars and students working on the debate about realism in philosophy of science.

Theoretical realism claims—against instrumentalism, constructive empiricism, entity realism, and structural realism —that the theoretical terms of successful scientific theories refer to real entities in the world, even beyond the edge of direct observability, and the principles and laws in theories are true. Critical realism qualifies this view by employing the notion of truthlikeness, which in particular applies to theories containing approximations and idealizations. The notion of truthlikeness also allows a precise formulation of a charitable account of reference for theoretical terms: (...) unlike in Fregean approaches, a theory may refer to an entity even though its description is only approximately true or truthlike. This shows that rival or successive theories may refer to the same entities in spite of the phenomenon of meaning variance or incommensurability. Illustrations of the realism debates are given in the fields of astronomy, quantum mechanics, psychology, and economics. (shrink)

The aim of this dissertation is to explore a central aspect of Berkeley's philosophy of science, namely, his philosophical account of the status of Newton's mechanics. In De Motu, Berkeley's treatise on mechanics, he makes plain that he accepts Newton's mechanics as an excellent scientific theory, while refusing to admit the existence of physical forces. Thus, Berkeley is an anti-realist about Newtonian mechanics. In the dissertation, I seek to identify the grounds and nature of this anti-realism. ;Although Berkeley's motivations for (...) maintaining dynamical anti-realism are largely metaphysical , Berkeley's case against realism in De Motu does not presuppose an immaterialist metaphysics. Rather, his main argument in De Motu is based on a strict empiricism and a claim about the conceptual requirements for reference. Essentially, Berkeley maintains that we can't understand dynamics realistically because we lack any appropriate concepts of force, nor can we acquire any, given the sort of things that forces are supposed to be. Other ways in which Berkeley impugns dynamical realism in De Motu reveal interesting affinities between his position and Cartesianism. ;Berkeley's alternative to realism is, I argue, a sort of instrumentalism. Here I disagree with a number of commentators who have seen Berkeley as a reductionist, that is, someone who claims that dynamics is reducible to kinematics. I develop my interpretation of Berkeley's dynamical instrumentalism by showing how it is connected in important ways with his views about the aims of science and about the significant of action-guiding language. In conclusion, I contrast Berkeley's instrumentalism about forces with his realism about particles in Siris. (shrink)

We list, with discussions, various principles of scientific realism, in order to exhibit their diversity and to emphasize certain serious problems of formulation. Ontological and epistemological principles are distinguished. Within the former category, some framed in semantic terms (truth, reference) serve their purpose vis-a-vis instrumentalism (Part 1). They fail, however, to distinguish the realist from a wide variety of (constructional) empiricists. Part 2 seeks purely ontological formulations, so devised that the empiricist cannot reconstruct them from within. The main task here (...) is to characterize "independence of mind". A pair of notions, "physical invariance" and "anti-determination", seem to work. They enable us to assess anew "the problem of constructing the physical out of the phenomenal" (yielding certain clarifications demanded by Goodman). Modern cosmology, especially, is seen to present insuperable obstacles to such empiricist approaches to science. The final section on epistemological principles reveals a morass better avoided in favor of an elementary claim about perception, together with a rejection of any absolute observation/theory dichotomy. Finally, a positive, realist notion of "observable-in-principle" is sketched, and it is suggested that, from the perspective of relativistic cosmology, even this defines no boundary to potential knowledge.

For a good part of the 20th century, the classic Pragmatists--Charles Sanders Peirce, William James, and John Dewey--and pragmatism in general were largely ignored by analytic philosophers. They were said to hold such untenable views as whatever best satisfies our needs is true and that the end justifies the means. Despite a recent revival of interest in these figures, spurred largely by the work of Richard Rorty, it is not uncommon to continue to hear claims that pragmatism is a subjectivist, (...) anti-realist position that denies that there is a mind-independent world, and fails to place objective constraints on inquiry. In this book, Robert Schwartz dispels these traditional views by examining the empiricist and constructivist orientation of the classic pragmatists. Based on updated and expanded versions of his influential papers, as well as a number of previously unpublished essays, in this book Schwartz demonstrates the relevance of pragmatic thought to a wide range of issues beyond concerns over truth and realism that currently dominate discussions. The individual essays elaborate and defend pragmatic, instrumentalist, and constructivist conceptions of truth and inquiry, moral discourse and ethical statements, perception, art, and worldmaking. Pragmatic Perspectives will appeal to scholars interested in the history of American philosophy and pragmatic approaches to contemporary issues in analytic philosophy. (shrink)

Pragmatic Scientific Realism (PSR) urges us to take up the realist aim or the goal of truth although we have good reason to think that the goal can neither be attained nor approximated. While Newton-Smith thinks that pursuing what we know we cannot achieve is clearly irrational, Rescher disagrees and contends that pursuing an unreachable goal can be rational on pragmatic grounds—if in pursuing the unreachable goal one can get indirect benefits. I have blocked this attempt at providing a pragmatic (...) justification for the realist aim of PSR on precisely the same pragmatic grounds—since there is a competing alternative to PSR, and the alternative can provide whatever indirect benefits PSR can offer while being less risky than it is, prudential reasoning favours the alternative to PSR. This undermines the pragmatic case for the realist aim of science since the instrumentalist alternative does not aim at the truth. (shrink)

This paper argues the case for ontological realism as against various present‐day forms of conventionalist, instrumentalist, cultural‐relativist, or anti‐realist doctrine. In particular it takes issue with Richard Rorty’s writings on philosophy of science – where these ideas receive their most extreme and provocative statement – and with Bas van Fraassen’s more moderate ‘constructive empiricist’ approach. This latter entails ontological commitment to whatever shows up through trained observation or empirical research. However, it refuses to countenance realist claims concerning the existence of (...) (as yet) unobserved entities and their role in explanatory theories premised on putative laws of nature. I maintain that van Fraassen’s position is: (1) inadequate to account for our knowledge of the growth of scientific knowledge; (2) self‐refuting since often undermined by examples which he himself supplies; and (3) incapable of mounting resistance to other, more wholesale (e.g., Rortian) varieties of anti‐realist argument. Only by combining causal realism with a principle of inference to the best explanation can philosophy of science avoid these kinds of hyperinduced sceptical doubt. (shrink)

The recent debate around scientific realism has taken an epistemic turn. The issue is no longer whether theoretical discourse is or is not assertoric (truth-valuable), nor whether theoretical discourse can be reduced to observational discourse. All sides of the present debate have left behind traditional instrumentalism and reductive empiricism. Instead, they endorse semantic realism which suggests that theoretical discourse (that is, statements about theoretical entities) should be understood literally and be taken to be assertoric and irreducible. In this setting, the (...) philosophical reaction to realism challenges the grounds for the realists’ belief in the existence of the unobservable entities posited by theories and in the truth of the assertions made about them. This reaction can take different shapes. But the dominant one, coming from van Fraassen’s constructive empiricism, is that an empiricist cannot be rationally forced to be a scientific realist. In his view, an empiricist can understand scientific theories literally but remain agnostic as to the truth (or falsity) of their theoretical assertions. Besides, if an empiricist decides to accept a theory he accepts it not as true but as empirically adequate. (shrink)

Derek Turner believes that a proper interpretation of Arthur Fine’s natural ontological attitude can help to reveal the nature of the difference between «historical» (geology, archeology, forensics) and «empirical» (physics, chemistry) sciences. From his point of view, the apparent asymmetry between these sciences is a consequence of different understanding of the possibilities to «manipulate» the objects of study and the role played by background theories. In our opinion, Turner’s concept is a good example of how profound and inviting the instrumentalistic (...) concept of science could be. First, it is «reflexive» in the sense that it constrained other instrumentalist theories (B. Fraassen’s constructive empiricism deeply flawed). And secondly, it is «constructive» – the emphasis that «the strength of arguments for or against scientific real- ism can vary depending on the scientific context» quite unexpectedly leads to the fact that «ideographic / nomothetic division is not very helpful», and to the fact that «epistemic disadvantage, but the same epis- temic status».

Charles Stein discovered a paradox in 1955 that many statisticians think is of fundamental importance. Here we explore its philosophical implications. We outline the nature of Stein’s result and of subsequent work on shrinkage estimators; then we describe how these results are related to Bayesianism and to model selection criteria like AIC. We also discuss their bearing on scientific realism and instrumentalism. We argue that results concerning shrinkage estimators underwrite a surprising form of holistic pragmatism.

At this stage of evolution of our discipline, philosophy of science, there seems no single great theme that has attracted the attention of most practitioners in the field. Rather, scholarly works in the field are quite diffused. Traditional topics, such as reductionism and the unity of science, remain to be carefully examined from various perspectives. The debate over realism versus instrumentalism, although dismissed by some as uninteresting and unproductive, is still taken by many active scholars as vital in our understanding (...) of the nature of scientific theories and in our appraisal of scientific enterprise. Of course, the new spirit of our times has also shown itself, sometimes in the discussion of some major theses in the post-empiricist philosophy of science, such as incommensurability, underdetermination and constructivism, on the basis of detailed examination of scientific materials, other times in the shift of the attention from static aspects of science, such as theory justification and the nature of explanation, to more dynamic aspects, such as negotiations within a scientific community and its function and role in the development of science. Even more to the point in this regard is the great attention paid to the place science has occupied in modernity, the defect of modernist understanding of science and its possible remedy. Not surprisingly, this current state of affairs in our field has also manifested in the essays collected in this volume of contributions to the Twentieth World Congress of Philosophy. Thus, an inspection of these essays, although it will not provide us with a focus of the discipline, may give us some sense as to what is going on in the field. (shrink)

Philosophers of history can be divided into two schools, the realist/ empiricist and the instrumentalist/ constructionist. Both accept that the evidence of the past is given. The "myth of evidence," however, obscures the problematic character of description and prediction as essential activities of historians and archaeologists. To choose between competing claims about a particular event one does not choose between the individual descriptions. Rather, one chooses those narratives with the wider network of truth statements and predictive powers. Once the "myth (...) of evidence" is dispelled, the philosophy of history should provide analyses and programs of data-description and prediction. (shrink)

The debate between realism and instrumentalism is at an impasse. That is the state of the art, and the competing positions and arguments are best understood by seeing how they have produced it. When scientists familiar with a common body of evidence, and with the resources of alternative theories for handling that evidence, nevertheless disagree as to which theory is best, something has gone wrong methodologically. Standards of evidential warrant, the criteria by which theories are to be judged, and not (...) just the theories themselves, are in dispute. When philosophers disagree about theories of science, without disputing the evidence brought to bear for or against the contenders, the legitimacy of standards of philosophical argument is similarly unresolved. In the debate over realism the central bone of contention is abductive inference. (shrink)

This book explores important topics in Darwin’s theory of evolution and in the twentieth- and twenty-first-century theories that grew out of it. These topics include fitness, adaptation, altruism, intragenomic conflict, units of selection, genetic drift, the randomness of mutation, gradualism, common ancestry, taxonomy, race, phylogenetic inference, and optimality models. The book brings these and other biological topics into contact with numerous philosophical ideas − operationalism, reductionism, conventionalism, null hypotheses and default reasoning, instrumentalism versus realism, likelihoods versus probabilities, model selection, essentialism, (...) falsifiability, parsimony, the principle of the common cause, comparisons of causal power, interpretations of probaiblity, indeterminism, sensitivity to initial conditions, and the knowability of the past.

The book revives the neutral monism of Mach, James, and Russell and applies the updated view to the problem of redefining physicalism, explaining the origins of sensation, and the problem of deriving extended physical objects and systems from an ontology of events.

Sometimes a theory is interpreted realistically--i.e., as literally true--whereas sometimes a theory is interpreted instrumentalistically--i.e., as merely a convenient device for summarizing, systematizing, deducing, etc., a given body of observable facts. This paper is part of a program aimed at determining the basis on which scientists decide on which of these interpretations to accept a theory. I proceed by examining one case: the nineteenth-century debates about the existence of atoms. I argue that there was a gradual transition from an instrumentalist (...) to a realistic acceptance of the atomic theory, because of gradual increases in its predictive power, the "testedness" of its hypotheses, the "determinateness" of its quantities, and because of resolutions of doubts about the acceptability of its basic explanatory concepts.

Recent contributions by Kuhn, Wartofsky, and Granger, converge in the direction of an extended view of models, one that acknowledges a metaphorical dimension in the language of science. Such a view is in some respects the opposite of the views of both Bachelard and the Logical Empiricists. A number of familiar puzzles of the philosophy of science, such as the problem of reference, the opposition of realism and instrumentalism, that between explanation and understanding, and the status of scientific objectivity, may (...) receive a new solution in the light of the Kuhn/Wartofsky/Granger view of scientific metaphors.

This article views the confrontation between pragmatism and Kant’s Critical undertaking as very possibly the single most consequential agon of contemporary philosophy, given the utter irreconcilability of their respective ways of addressing the concerns of First Philosophy, with regard to the enabling conditions of cognitive realism. Pragmatism favors an informal, fluxive, “instrumentalist” form of empiricism, impossible to complete, opposed to any and all the ontic and epistemic fixities of Kant’s Rationalism. Reason (Vernunft) cannot be more than a fiction. Kant has (...) no supporting criterion of realism. The article proposes an empirical criterion of the distinctive (given) “duality” of sensory “appearings” and “appeareds” (that is, objects) as yielding a plausible “cognitive faculty” (involving “reasoning”—inference, for instance—but not Vernunft) that, in accord with the drift of evolutionism and Aristotle, readily extends to languageless animals as well as humans. It serves as the linchpin of the paper. (shrink)

: We question the claim, common since Duhem, that sixteenth century astronomy, and especially the Wittenberg interpretation of Copernicus, was instrumentalistic rather than realistic. We identify a previously unrecognized Wittenberg astronomer, Edo Hildericus (Hilderich von Varel), who presents a detailed exposition of Copernicus's cosmology that is incompatible with instrumentalism. Quotations from other sixteenth century astronomers show that knowledge of the real configuration of the heavens was unattainable practically, rather than in principle. Astronomy was limited to quia demonstrations, although demonstration propter (...) quid remained the ideal. We suggest that Osiander's notorious preface to Copernicus expresses these sixteenth century commonplaces rather than twentieth century instrumentalism, and that neither `realism', nor `instrumentalism', in their modern meanings, apply to sixteenth century astronomy.

There are two distinct approaches to Bayesian modelling in cognitive science. Black-box approaches use Bayesian theory to model the relationship between the inputs and outputs of a cognitive system without reference to the mediating causal processes; while mechanistic approaches make claims about the neural mechanisms which generate the outputs from the inputs. This paper concerns the relationship between these two approaches. We argue that the dominant trend in the philosophical literature, which characterizes the relationship between black-box and mechanistic approaches to (...) Bayesian cognitive science in terms of the dichotomy between instrumentalism and realism, is misguided. We propose that the two distinctions are orthogonal: black-box and mechanistic approaches to Bayesian modelling can each be given either an instrumentalist or a realist interpretation. We argue that the current tendency to conflate black-box approaches with instrumentalism and mechanistic approaches with realism stems from unwarranted assumptions about the nature of scientific explanation, the ontological commitments of scientific theories, and the role of abstraction and idealization in scientific models. We challenge each of these assumptions to reframe the debates over Bayesian modelling in cognitive science. (shrink)

The choice between realism and instrumentalism is at the core of concerns about how our scientific models relate to reality: Do our models aim to be literally true descriptions of reality, or is their role only as useful instruments for generating predictions? Realism about X, roughly speaking, is the claim that X exists and has its nature independent of our interests, attitudes, and beliefs. An instrumentalist about X denies this. She claims that talk of X should be understood as no (...) more than a useful locution for generating predictions, such talk should not be understood as taking on a commitment to the existence of X. According to an instrumentalist, we should either flatly not believe that X is out there, or else suspend judgement about the existence of X. The most we need acknowledge is that talk of X is useful in making predictions. The question of realism vs. instrumentalism can be asked about almost any theoretical entity in science. It is likely, and seems reasonable, that different answers will be given in different cases. Someone may wish to be a realist about certain theoretical entities (e.g. electrons), but an instrumentalist about others (e.g. centres of gravity). Not every noun-phrase in a scientific theory should be taken as expressing an ontological commitment. Psychological theories are no exception. Almost every theoretical posit in psychology has been questioned as to whether it is really out there or just a useful theoretical fiction. In this entry, I will focus on two major theoretical posits in psychology: (a) propositional attitudes (e.g. beliefs, desires) and (b) conscious states (qualia). (shrink)

The main claim of the paper is that one can be ‘realist’ (in some sense) about quantum mechanics without requiring any form of realism about the wave function. We begin by discussing various forms of realism about the wave function, namely Albert’s configuration-space realism, Dürr Zanghi and Goldstein’s nomological realism about Ψ, Esfeld’s dispositional reading of Ψ Pusey Barrett and Rudolph’s realism about the quantum state. By discussing the articulation of these four positions, and their interrelation, we conclude that instrumentalism (...) about Ψ is by itself not sufficient to choose one over the other interpretations of quantum mechanics, thereby confirming in a different way the indetermination of the metaphysical interpretations of quantum mechanics. -/- Key words: .

The realist programme has degenerated by now to the point where it is quite beyond salvage. A token of this degeneration is that there are altogether too many realisms. It is as though by splitting into a confusing array of types and kinds, realism has hoped that some one variety might yet escape extinct. I shall survey the debate, and some of these realisms, below. Here I would just point out the obvious; that in so far as the successes of (...) science mount while realism continues to decline we must conclude that scientific success lends no support to realism. Since it is unlikely to support anti-realism, we have some reason to suspect that the philosophical debate over realism does not concern issues that can be settled by developments in the sciences, no matter how successful science may be. Further, since that success grounds a culture of acceptance for science and its entities, we have reason to believe that the existence of those entities is also not actually the issue that concerns realism. Afortiori, it is not the issue that concerns anti-realism either; nor, I might add, is anti-realism the winner in the philosophical debate that realism has lost. (shrink)

The roles of classical realism, logical positivism, and pragmatic instrumentalism in the shaping of fundamental ideas in quantum physics are examined in the light of some recent historical and sociological studies of the factors that influenced their development. It is shown that those studies indicate that the conventionalistic form of instrumentalism that has dominated all the major post-World War II developments in quantum physics is not an outgrowth of the Copenhagen school, and that despite the “schism” in twentieth century physics (...) created by the Bohr-Einstein “disagreements” on foundational issues in quantum theory, both their philosophical stands were very much opposed to those of conventionalistic instrumentalism. Quotations from the writings of Dirac, Heisenberg, Popper, Russell, and other influential thinkers, are provided, illustrating the fact that, despite the various divergencies in their opinions, they all either opposed the instrumentalist concept of “truth” in general, or its conventionalistic version in post-World War II quantum physics in particular. The basic epistemic ideas of a quantum geometry approach to quantum physics are reviewed and discussed from the point of view of a quantum realism that seeks to reconcile Bohr's “positivism” with Einstein's “realism” by emphasizing the existence of an underlying quantum reality, in which they both believed. This quantum geometry framework seeks to introduce geometro-stochastic concepts that are specifically designed for the systematic description of that underlying quantum reality, by developing the conceptual and mathematical tools that are most appropriate for such a use.

There is a salient contrast in how theoretical representations are regarded. Some are regarded as revealing the nature of what they represent, as in familiar cases of theoretical identification in physical chemistry where water is represented as hydrogen hydroxide and gold is represented as the element with atomic number 79. Other theoretical representations are regarded as serving other explanatory aims without being taken individually to reveal the nature of what they represent, as in the representation of gold as a standard (...) for pre-20th century monetary systems in economics or the representation of the meaning of an English sentence as a function from possible worlds to truth values in truth-conditional semantics. Call the first attitude towards a theoretical representation *realist* and the second attitude *instrumentalist*. Philosophical explanation purports to reveal the nature of whatever falls within its purview, so it would appear that a realist attitude towards its representations is a natural default. I offer reasons for skepticism about such default realism that emerge from attending to several case studies of philosophical explanation and drawing a general metaphilosophical moral from the foregoing discussion.

Richard Boyd and Nicholas Sturgeon develop distinctive naturalistic arguments for scientific realism and moral realism. Each defends a realist position by an inference to the best explanation. In this paper, I suggest that these arguments for realism should be reformulated, with the law of likelihood replacing inference to the best explanation. The resulting arguments for realism do not work.

Stein has raised a fundamental problem for any attempt to characterize instrumentalism and realism as substantive alternatives. This is the distinguishability problem, which consists in the problem of developing a form of instrumentalism that is substantially different from a plausible realist alternative and the problem of showing that this form of instrumentalism does justice to actual scientific practice. Using Stein’s own discussion of Maxwell, I formulate instrumentalism and realism as a scientist’s attitudes toward models, where an attitude is understood to (...) be a complex of the scientist’s belief and intention regarding models. Developing a case study of Benzer’s modeling practice, I show that each attitude can structure inquiry differently and argue that to understand certain aspects of scientific practice, such as the practice of genetic mapping in Benzer’s work, we sometimes need to appeal to the coexistence of these attitudes.

In this paper, I offer a new defense of scientific realism, tailored for the Akaikean paradigm of statistical hypothesis testing. After proposing definitions of verisimilitude and predictive success, I use computer simulations to show how the latter depends on the former, even in the kind of case featured in a recent argument for instrumentalism.

Several lines of argument support the notion that the legacy of positivism (if cast in terms of the realist/instrumentalist debate) is more realist than not. Work by Joia Lewis and Alberto Coffa on both Schlick and Carnap is cited, and contemporary work from Van Fraassen and Boyd briefly alluded to. Note is made of the differences within contemporary realist theory, and it is included that Carnap's essay "Empiricism, Semantics and Ontology" is crucial for resolution of the debate. In closing it (...) is noted that the spirit of much of the original positivist work reinforced the contention than those who work within the framework of science do in fact accept the reality of key scientific entities.

The logical empiricists knew that scientific theories sometimes arise out of the attempt to reconcile or unify two existing theories. They also thought that, at best, old theories would be retained as approximations to their successors. Kuhn lost both insights when he rejected the logical empiricists' formal approach in favor of an exclusively historical and psychological one. But when Putnam tried to restore such ideas he failed to provide them with the historical support they require. An account of revolutionary unifications (...) is defended as reconciling Putnam's realist ideas about methodology with Kuhn's historical approach. (shrink)

This paper defends an approach to modeling and models in science that is against model fictionalism of a recent stripe (the “new fictionalism” that takes models to be abstract entities that are analogous to works of fiction). It further argues that there is a version of fictionalism on models to which my approach is neutral and which only makes sense if one adopts a special sort of antirealism (e.g. constructive empiricism). Otherwise, my approach strongly suggests that one stays away from (...) fictionalism and embraces realism directly. (shrink)
