The aim of this essay is to argue for a new version of ‘inference-to-the-best-explanation’ scientific realism, which I characterize as Best Theory Realism or ‘BTR’. On BTR, the realist needs only to embrace a commitment to the truth or approximate truth of the best theories in a field, those which are unique in satisfying the highest standards of empirical success in a mature field with many successful but falsified predecessors. I argue that taking our (...) best theories to be true is justified because it provides the best explanation of the predictive success of their predecessors and their own special success. Against standard and especially structural realism, I argue against the claim that the best explanations of the success of theories is provided by identifying their true components, such as structural relations between unobservable, which are preserved across theory change. In particular, I criticize Ladyman's and Carrier’s structural account of the success of phlogiston theory, and Worrall's well-known structural account of the success of Fresnel’s theory of light. I argue that these accounts tacitly assume the truth of our best theories, which in any case provides a better explanation of these theories’ success than the structural account. Structural realism is now defended as the only version of realism that is able to surmount the pessimistic meta-induction and the general problem that successful theories involve ontological claims concerning unobservable entities that are abandoned and falsified in theory-change. I argue that Best Theory Realism can overcome the pessimistic meta-induction and this general problem posed by theory-change. Our best theories possess a characteristic which sharply distinguishes them from their successful but false predecessors. Furthermore ‘inference-to-the-best-explanation’ confirmation can establish the truth of our best theories and thus trumps the pessimistic inductive reasoning which is supposed to show that even our best theories are most likely false in their claims concerning unobservable entities and processes.

The no-miracles argument is the main inference-to-the-best-explanation kind of argument for scientific realism, and the pessimistic induction is considered a main, if not the main, challenge for a NMA-based scientific realism. Doppelt advocates a new kind of inference-to-the-best-explanation supported scientific realism that he labels Best Theory Realism. If successful in replacing standard selective realism as the best version of scientific realism, BTR would be particularly good since it is not (...) committed to the partial truth of past theories and thereby it is immune to the antirealist strategy of finding cases of past, predictively successful theories with predictively essential components not retained by later theories. The goal of this paper is to raise doubts about Doppelt’s attempt and argue that, other benefits of his proposal notwithstanding, it fails. In section 1 I summarize the main tenets of standard, retentive selective realism relevant for the present discussion. In section 2 I show that Doppelt’s main arguments against retentive selective realism do not work. In section 3, I argue that the way BTR faces the challenge posed by the historical record that motivates PI is unsatisfactory and puts Doppelt into a fatal trilemma: either he is committed to two claims that are untenable together; or endorses an extremely implausible form of present-science chauvinism; or unjustifiably discriminates explanation against prediction in historical record. The conclusion is that BTR falls short of substituting standard retentive selective realism as the most plausible realist position, and that thereby the cases of past successful theories with predictively essential parts not retained by posterior theories are still a real problem for a plausible realist position.

I defend a realist commitment to the truth of our most empirically successful current scientific theories—on the ground that it provides the best explanation of their success and the success of their falsified predecessors. I argue that this Best Current Theory Realism (BCTR) is superior to preservative realism (PR) and the structural realism (SR). I show that PR and SR rest on the implausible assumption that the success of outdated theories requires the realist to (...) hold that these theories possessed truthful components. PR is undone by the fact that past theories succeeded even though their ontological claims about unobservables are false. SR backpeddles to argue that the realist is only committed to the truth about the structure of relations implied by the outdated theory, in order to explain its success. I argue that the structural component of theories is too bare-bones thin to explain the predictive/explanatory success of outdated theories. I conclude that BCTR can meet these objections to PR and SR, and also overcome the pessimistic meta-induction. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Sport Realism: A Law-Inspired Theory of Sport by Aaron HARPERTim ElcombeHARPER, Aaron. Sport Realism: A Law-Inspired Theory of Sport. Lanham, Md.: Lexington Books, 2022. viii + 172 pp. Cloth, $95.00At a crucial moment in the 2019 World Series all six on-field umpires, in communication with Major League Baseball’s headquarters, engaged in an 8-minute discussion to determine if a baserunner should be called out for (...) interference. The deliberation stemmed from a tension between the formal rules of baseball and the game’s unwritten rules about a baserunner’s traveled path to first base. This example of a “hard case” in sport officiating sets Aaron Harper’s book Sport Realism: A Law-Inspired Theory of Sport in motion. Harper’s aim in Sport Realism is to provide a new “theory of sport” drawing primarily from American legal realism—and supplemented by philosophical pragmatism and virtue jurisprudence. Sport realism, Harper argues, serves as the best resource to understand how rules are applied in sport and how officials make in-game decisions, and it highlights the importance of participants being able to develop an expectation for how calls will be made in the future and to make difficult normative judgments.In chapter 1, Harper provides an excellent overview of the sport philosophy literature related to “theories of sport.” Using a chronological approach, he develops a clear and extensive “history” of the evolution of the field’s most influential theories and their connections to legal theory. Harper summarizes how formalism’s rigid commitment to “constitutive” rules that supposedly define a sport led to criticisms from conventionalists who alternatively generated their account of how nonwritten rules or a sporting ethos defines how a sport is played. However, the laissez-faire nature of conventionalism, as well as the inflexibility of formalism, gave rise to now-dominant interpretivist theories of sport that Harper covers in significant detail. Primarily inspired by Ronald Dworkin, philosophers developed theories that relied on the interpretation of principles that affirmed a sport’s point and purpose. Emergent formulations of interpretivism—from realist accounts to antirealist/historicist versions—all relied on the interpretation of some essential starting point (rules, principles, ethos, deep conventions) to both explain sport and provide officials with normative guidance.Harper regularly lauds interpretivism as the best theory of sport developed to date. However, in chapter 2 he highlights deficiencies with interpretivist accounts via two case studies: New York Yankees’ pitcher Michael Pineda’s “illegal” use of pine tar to improve his grip on the [End Page 147] baseball, as well as Tiger Woods taking a favorable drop after hitting his golf ball into a water hazard. From these two cases, Harper concludes that all variations of interpretivism (from realist to antirealist accounts) fall short in the purpose of developing a theory of sport: to both explain sport (Pineda case) and give a wide swath of formal and informal decision-makers tools to make difficult ethical judgments (Woods case).Harper turns to American legal realism in chapter 3 to develop a superior theory of sport. Crucial to Harper’s sport realism account is Oliver Wendell Holmes’s resistance to understanding law as a set of rules or principles, and instead as an ongoing process of “policymaking” best characterized by the role of the appellate courts. “Understanding the law” from a Holmes perspective, Harper writes, “entails successful prediction of how courts will act in deciding cases... which actions will, in fact, prompt sanction by a court.” This alternative view of the law led to the rise of American legal realism—and subsequently serves as the source of Harper’s sport realism account sketched out in the latter half of chapter 3. According to sport realism, sport ought to be explained by how “it is actually played in order to provide a more accurate account of sport as an activity.” This “best explanation of sport” therefore “provides normative guidance” for sporting challenges.Continuing his development of sport realism, Harper sets out in chapter 4 to define cheating as “an instance of rule-breaking [that] warrants a restorative sanction given by sport officials, and we would expect such sanction to be given if the action...

It is common for contemporary metaphysical realists to adopt Quine's criterion of ontological commitment while at the same time repudiating his ontological pragmatism. 2 Drawing heavily from the work of others—especially Joseph Melia and Stephen Yablo—I will argue that the resulting approach to meta-ontology is unstable. In particular, if we are metaphysical realists, we need not accept ontological commitment to whatever is quantified over by our best first-order theories.

An interesting consequence of the structuralist theory of truth approximation, as developed in my From Instrumentalism to Constructive Realism, henceforth ICR, concerns so-called ‘inference to the best explanation’. It will be argued that this popular rule among scientific realists can better be replaced by, various kinds of, ‘inference to the best theory’.

This book is a critical introduction to the long-standing debate concerning the conceptual foundations of quantum mechanics and the problems it has posed for physicists and philosophers from Einstein to the present. Quantum theory has been a major infulence on postmodernism, and presents significant problems for realists. Keeping his own realist position in check, Christopher Norris subjects a wide range of key opponents and supporters of realism to a high and equal level of scrutiny. With a characteristic combination (...) of rigour and intellectual generosity, he draws out the merits and weaknesses from opposing arguments. In a sequence of closely argued chapters, Norris examines the premises of orthodox quantum theory, as developed most influentially by Bohr and Heisenberg, and its impact on varous philosophical developments. These include the ideas developed by W.V Quine, Thomas Kuhn, Michael Dummett, Bas van Fraassen, and Hilary Puttnam. In each case, Norris argues, these thinkers have been influenced by the orthodox construal of quantum mechanics as requiring drastic revision of principles which had hitherto defined the very nature of scientific method, causal explanati and rational enquiry. Putting the case for a realist approach which adheres to well-tried scientific principles of causal reasoning and inference to the best explanation, Christopher Norris clarifies these debates to a non-specialist readership and scholars of philosophy, science studies and the philosophy of science alike. Quantum Theory and the Flight From Realism suggests that philosophical reflection can contribute to a better understanding of these crucial, current issues. (shrink)

How can we have a sense of the presence of ordinary three-dimensional objects (e.g., an apple on my desk, a partially occluded cat behind a picket fence) when we are only presented with some parts of objects perceived from a particular egocentric viewpoint (e.g., the facing side of the apple, the unoccluded parts of the cat)? This paper presents and defends a novel answer to this question by incorporating insights from two prominent contemporary theories of perception, naïve realism and (...) sensorimotor theory. Naïve realism is the view that perception is fundamentally a matter of obtaining a relation of ‘acquaintance’ with some mind-independent entities (e.g., objects, properties, events). Sensorimotor theory holds that perception involves implicit practical understanding or ‘anticipation’ of the covariance between movements and sensory changes. I argue that perceptual presence is best accounted for in terms of the combination of our direct ‘acquaintance’ with some parts of perceived objects and sensorimotor ‘anticipations’ of how the objects would look different depending on some movements and actions.

Williams and J. Fraser have recently argued that effective field theory methods enable scientific realists to make more reliable ontological commitments in quantum field theory than those commonly made. In this paper, I show that the interpretative relevance of these methods extends beyond the specific context of QFT by identifying common structural features shared by effective theories across physics. In particular, I argue that effective theories are best characterized by the fact that they contain intrinsic empirical limitations, (...) and I extract from their structure one central interpretative constraint for making more reliable ontological commitments in different subfields of physics. While this is in principle good news, this constraint still raises a challenge for scientific realists in some contexts, and I bring the point home by focusing on Williams’s and J. Fraser’s defense of selective realism in QFT. (shrink)

Despite the fact about colour, that it is one of the most obvious and conspicuous features of the world, there is a vast number of different theories about colour, theories which seem to be proliferating rather than decreasing. How is it possible that there can be so much disagreement about what colours are? Is it possible that these different theorists are not talking about the same thing? Could it be that more than one of them is right? Indeed some theorists, (...) e.g. Leo M. Hurvich, D. L. McAdam and K. Nassau, say that the term ‘colour’ is used to identify a range of different properties, e.g. pigments, properties of light, and sensations. Such a view has its attractions, but it raises the question of what it is that unites these various concepts – what is it that would make them all concepts of colour? What is it that justifies using the same terms, ‘yellow’, ‘blue’, ‘pink’, mauve’, and so on?This paper aims to address this question, arguing that its answer supports the conclusion that the best theory of colour is a form of anti‐realism: the Illusory theory of colours. There are two parts to this thesis, one negative, the other positive. The negative part is that there are no colours, as they are ordinarily conceived. The positive part is that, nevertheless, the world is such that ‘it is as if there are such colours’. Such a theory has important implications. One is that it doesn’t fall neatly into the usual taxonomy of philosophical theories. In particular, it does not deserve the label ‘eliminativist’. Another is that it allows some space for the views expressed by Hurvich, McAdam and Nassau, but not quite in the sense that they intend. (shrink)

There are two possible realist defense strategies against the pessimistic meta-induction and Laudan’s meta-modus tollens: the selective strategy, claiming that discarded theories are partially true, and the discontinuity strategy, denying that pessimism about past theories can be extended to current ones. A radical version of discontinuity realism is proposed by Gerald Doppelt: rather than discriminating between true and false components within theories, he holds that superseded theories cannot be shown to be even partially true, while present best theories (...) are demonstrably completely true. I argue that this position, running counter both the cumulativity of science and fallibilism, is untenable; it cannot account for the success of past theories, nor for the failures of current theories, and rather than shutting the door to the pessimistic historical objections it opens it wide. The best strategy, instead, joins the selective idea there was both some truth and some falsity in discarded theories, like in current ones, with the moderate discontinuity idea that the truth rate in present best theories is much greater than in past ones.

Is there more to the recent surge in political realism than just a debate on how best to continue doing what political theorists are already doing? I use two recent books, by Michael Freeden and Matt Sleat, as a testing ground for realism’s claims about its import on the discipline. I argue that both book take realism beyond the Methodenstreit, though each in a different direction: Freeden’s takes us in the realm of meta-metatheory, Sleat’s is a (...) genuine exercise in grounding liberal normative theory in a non-moralistic way. I conclude with wider methodological observations. I argue that unlike communitarianism (the previous contender for the discipline’s renewal), realism has the potential to open new vistas, though their novelty is to a large extent relative to the last forty years or so: realism is best thought of as a return to a more traditional way of doing political philosophy.

A Naive Realist Theory of Colour defends the view that colours are mind-independent properties of things in the environment, that are distinct from properties identified by the physical sciences. This view stands in contrast to the long-standing and wide-spread view amongst philosophers and scientists that colours don't really exist - or at any rate, that if they do exist, then they are radically different from the way that they appear. It is argued that a naive realist theory of (...) colour best explains how colours appear to perceiving subjects, and that this view is not undermined either by reflecting on variations in colour perception between perceivers and across perceptual conditions, or by our modern scientific understanding of the world. A Naive Realist Theory of Colour also illustrates how our understanding of what colours are has far-reaching implications for wider questions about the nature of perceptual experience, the relationship between mind and world, the problem of consciousness, the apparent tension between common sense and scientific representations of the world, and even the very nature and possibility of philosophical inquiry.

In this paper I discuss the rule of inference proposed by Kuipers under the name of Inference to the Best Theory. In particular, I argue that the rule needs to be strengthened if it is to serve realist purposes. I further describe a method for testing, and perhaps eventually justifying, a suitably strengthened version of it.

This essay offers a critical appraisal of some claims recently advanced by Crispin Wright and others in support of a response-dispositional (RD) approach to issues in epistemology, ethics, political theory, and philosophy of the social sciences. These claims take a lead from Plato's discussion of the status of moral value-judgements in the Euthyphro and from Locke's account of 'secondary qualities' such as colour, texture and taste. The idea is that a suitably specified description of best opinion (or optimal (...) response) for some given area of discourse will provide all that is needed in the way of objectivity while avoiding the problems raised by anti-realists like Michael Dummett with respect to the existence of truth-values that transcend our utmost powers of recognition or verification. I focus on three main areas - mathematics, morals and constitutional law - and argue that an RD approach falls short in certain crucial respects. That is to say, it works out either as a trivial (tautological) claim to the effect that 'best judgement' cannot - per definiens - diverge from truth under conditions of idealized epistemic warrant, or as an approach that leans strongly towards the anti-realist side of the argument. Thus the promised 'third way' - here as in other present-day contexts of debate - most often carries no substantive implications for our thinking about truth, moral virtue, or justice. Elsewhere, especially when applied to juridical matters, it lays chief stress on the truth-constitutive role of human judgements or responses, and hence the impossibility of appealing to standards of natural justice beyond some existing highest authority or source of constitutional warrant. This point is made with specific reference to recent events surrounding the 'election' (or leverage-into-office) of President George W. Bush. In such cases, I conclude, an RD approach would tend strongly to endorse the view that 'best opinion' - as enshrined, say, in the deliverance of US Supreme Court justices - is the furthest we can get towards an adequate assessment of the moral and political issues. Key Words: anti-realism • ethics • judgement • mathematics • political theory • realism • response-dependence. (shrink)

This book offers a close and rigorous examination of the arguments for and against scientific realism and introduces key positions in the scientific realism/antirealism debate, which is one of the central debates in contemporary philosophy of science. On the one hand, scientific realists argue that we have good reasons to believe that our best scientific theories are approximately true because, if they were not even approximately true, they would not be able to explain and predict natural phenomena (...) with such impressive accuracy. On the other hand, antirealists argue that the success of science does not warrant belief in the approximate truth of our best scientific theories. This is because the history of science is a graveyard of theories that were once successful but were later discarded. The author eventually settles on a middle ground position between scientific realism and antirealism called "relative realism.". (shrink)

Debates about scientific realism are closely connected to almost everything else in the philosophy of science, for they concern the very nature of scientific knowledge. Scientific realism is a positive epistemic attitude toward the content of our best theories and models, recommending belief in both observable and unobservable aspects of the world described by the sciences. This epistemic attitude has important metaphysical and semantic dimensions, and these various commitments are contested by a number of rival epistemologies of (...) science, known collectively as forms of scientific antirealism. This article explains what scientific realism is, outlines its main variants, considers the most common arguments for and against the position, and contrasts it with its most important antirealist counterparts.

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)

Truthmaker theory begins with the idea that truth depends upon reality. When a truth-bearer is true, that is because something or other in the world makes it true. My dissertation offers a theory of truthmakers that shows how we should flesh out this thought while avoiding the contentious metaphysical commitments that are built into other truthmaker theories. Because of these commitments, many philosophers have come to view truthmaker theory as being essentially tied to correspondence theories of truth, (...) and to metaphysical realism. I argue that, quite to the contrary, truthmaker theory is distinct from correspondence theory, and that the former actually undermines the motivation for the latter. In fact, truthmaker theory can be used to argue for a particular kind of deflationism about truth. I also argue that debates about realism and anti-realism are best viewed through the lens of truthmaker theory, which is not—contrary to what many have thought—an essentially realist approach to metaphysics. Anti-realists of various stripes can also make use of truthmakers. The anti-realism of such views depends upon either the nature of the truthmakers they use, or the nature of the truthmaking relation itself. (shrink)

Scientific realism is a thesis about the success of science. Most traditionally: science has been so successful at prediction and guiding action because its best theories are true (or approximately true or increasing in their degree of truth). If science is in the business of doing its best to generate true theories, then we should turn to those theories for explanatory knowledge, predictions, and guidance of our actions and decisions. Views that are popular in contemporary philosophy of (...) science about scientific modeling and the centrality of idealization create several challenges for this traditional form of scientific realism. Yet the basic idea behind scientific realism that science has been and will continue to be epistemically successful is deeply appealing. This chapter explores the challenges posed by idealization and scientific modeling to motivate a scientific realism fully divorced from the idea that science is in the business of generating true theories. On the resulting view, the objects of scientific knowledge are causal patterns, so this knowledge only ever provides partial, simplified accounts of a complex reality. This variety of selective realism better accommodates the nature of our present-day scientific successes and offers an interpretation of scientific progress that resists the antirealist’s pessimism.

Ontic structural realism refers to the novel, exciting, and widely discussed basic idea that the structure of physical reality is genuinely relational. In its radical form, the doctrine claims that there are, in fact, no objects but only structure, i.e., relations. More moderate approaches state that objects have only relational but no intrinsic properties. In its most moderate and most tenable form, ontic structural realism assumes that at the most fundamental level of physical reality there are only relational (...) properties. This means that the most fundamental objects only possess relational but no non-reducible intrinsic properties. The present paper will argue that our currently best physics refutes even this most moderate form of ontic structural realism. More precisely, I will claim that 1) according to quantum field theory, the most fundamental objects of matter are quantum fields and not particles, and show that 2) according to the Standard Model, quantum fields have intrinsic non-relational properties.

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the (...) best confirmed theories in science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

This book addresses central issues in the philosophy and metaphysics of science, namely the nature of scientific theories, their partial truth, and the necessity of scientific laws within a moderate realist and empiricist perspective. Accordingly, good arguments in favour of the existence of unobservable entities postulated by our best theories, such as electrons, must be inductively grounded on perceptual experience and not their explanatory power as most defenders of scientific realism claim. Similarly, belief in the reality of dispositions (...) such as causal powers which ground the natural necessity of scientific laws must be based on experience. Hence, this book offers a synthetic presentation of an original metaphysics of science, namely a metaphysics of properties, both categorical and dispositional, while at the same time opposing strong versions of necessitarism according to which laws are true in all possible worlds. The main theses and arguments are clearly presented in a non-technical way. Thus, on top of being of interest to the specialists of the topics discussed, it is also useful as a textbook in courses for third year and more advanced university students. (shrink)

Scientific realism is the view that our best scientific theories can be regarded as (approximately) true. This is connected with the view that science, physics in particular, and metaphysics could (and should) inform one another: on the one hand, science tells us what the world is like, and on the other hand, metaphysical principles allow us to select between the various possible theories which are underdetermined by the data. Nonetheless, quantum mechanics has always been regarded as, at (...) class='Hi'>best, puzzling, if not contradictory. As such, it has been considered for a long time at odds with scientific realism, and thus a naturalized quantum metaphysics was deemed impossible. Luckily, now we have many quantum theories compatible with a realist interpretation. However, scientific realists assumed that the wave-function, regarded as the principal ingredient of quantum theories, had to represent a physical entity, and because of this they struggled with quantum superpositions. In this paper I discuss a particular approach which makes quantum mechanics compatible with scientific realism without doing that. In this approach, the wave-function does not represent matter which is instead represented by some spatio-temporal entity dubbed the primitive ontology: point-particles, continuous matter fields, space-time events. I argue how within this framework one develops a distinctive theory-construction schema, which allows to perform a more informed theory evaluation by analyzing the various ingredients of the approach and their inter-relations.

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt (...) any particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)

Derek Parfit defended Non-Realist Cognitivism. It is an open secret that this metaethical theory is often thought at best puzzling and at worst objectionably unclear. Employing truthmaker theory, I provide an account of Non-Realist Cognitivism that dispels charges of objectionable unclarity, clarifies how to assess it, and explains why, if plausible, it would be an attractive theory. I develop concerns that the theory involves cheating into an objection that ultimately reveals Non-Realist Cognitivism faces a dilemma. (...) Whether it can escape demands further attention. In bridging metaethics and the truthmaking literature, I illustrate the importance of greater meta-metaphysical reflection in metaethics. (shrink)

Many realist writings exemplify the spirit of ‘recipe realism’. Here I characterise recipe realism, challenge it, and propose replacing it with ‘exemplar realism’. This alternative understanding of realism is more piecemeal, robust, and better in tune with scientists’ own attitude towards their best theories, and thus to be preferred.

A prominent type of scientific realism holds that some important parts of our best current scientific theories are at least approximately true. According to such realists, radically distinct alternatives to these theories or theory-parts are unlikely to be approximately true. Thus one might be tempted to argue, as the prominent anti-realist Kyle Stanford recently did, that realists of this kind have little or no reason to encourage scientists to attempt to identify and develop theoretical alternatives that are (...) radically distinct from currently accepted theories in the relevant respects. In other words, it may seem that realists should recommend that scientists be relatively conservative in their theoretical endeavors. This paper aims to show that this argument is mistaken. While realists should indeed be less optimistic of finding radically distinct alternatives to replace current theories, realists also have greater reasons to value the outcomes of such searches. Interestingly, this holds both for successful and failed attempts to identify and develop such alternatives. (shrink)

Individual realism asserts that our best scientific theories are (approximately) true. In contrast, selective realism asserts that only the stable posits of our best scientific theories are true. Hence, individual realism recommends that we accept more of what our best scientific theories say about the world than selective realism does. The more scientists believe what their theories say about the world, the more they are motivated to exercise their imaginations and think up new (...) theories and experiments. Therefore, individual realism better fosters scientific creativity than selective realism. (shrink)

Critical realism, championed by its proponents as the most promising post-positivist social science paradigm, has gained significant influence in the last few decades. This paper provides a critical evaluation of the critical realism movement in the hope of facilitating more fruitful dialogues between its proponents and rivalling schools of sociologists. Two concerns are raised about contemporary critical realism. First, critical realism is not the only philosophical school against positivism and not necessarily the best. Second, critical (...) realists exaggerate the importance of critical realism to social science and conflate philosophy of science with sociological theories. (shrink)

There are realist and antirealist interpretations of the free energy principle (FEP). This paper aims to chart out a structural realist interpretation of FEP. To do so, it draws on Worrall’s (Dialectica 43(1–2): 99–124, 1989) proposal. The general insight of Worrall’s paper is that there is progress at the level of the structure of theories rather than their content. To enact Worrall’s strategy in the context of FEP, this paper will focus on characterising the formal continuity between fundamental equations of (...) thermodynamics—such as Boltzmann’s equation and Gibbs’s equation—on the one hand, and Friston’s characterisation of FEP on the other. Lack of a universal consensus on the physical character of entities that feature in thermodynamics, information theory and FEP notwithstanding, I argue that there is structural continuity and unity at the level of mathematical equations that regiment entropy, information and free energy. The existence of such structural continuity and unity provides grounds for structural realism about FEP. (shrink)

In this essay, I critically evaluate the approaches to explaining the success of science in Kuhn and the works of inference-to-the-best-explanation scientific realists. Kuhn ’s challenge to realists, who invoke the truth of theories to explain their success, is two-fold. His paradigm-account of success confronts realists with the problem of theory change, and the historical fact of successful theories later rejected as false. Secondly, Kuhn ’s account of the success of science has no need to bring truth into (...) the explanation. In turn, I argue that weakness in Kuhn and the prevailing forms of scientific realism motivate a better account of realism which I characterize as ‘best current theory realism’ and defend against the pessimistic meta-induction and the problem of theory-change. This realism argues that the best explanation of the success of current and past scientific theories only requires the simple claim that our best current theories are true. Kuhn ’s account can explain how normal science succeeds but cannot account for why its problem solutions work where they do and why they fail for other puzzles. (shrink)

I examine Carrier’s and Ladyman’s structural realist explanation of the predictive success of phlogiston chemistry. On their account, it succeeds because phlogiston chemists grasped that there is some common unobservable structure of relations underlying combustion, calcification, and respiration. I argue that this SR account depends on assuming the truth of current chemical theory of oxidation and reduction, which provides a better explanation of the success of phlogiston theory than SR provides. I defend an alternative version of inference-to-the-best-explanation (...) scientific realism which I call ‘Best Current Theory Realism’ and argue that it can answer the pessimistic meta-induction.

Scientific realism has been advanced as an interpretation of the natural sciences but never the behavioral sciences. This book introduces a novel version of scientific realism, Measured Realism, that characterizes the kind of theoretical progress in the social and psychological sciences that is uneven but indisputable. It proposes a theory of measurement, Population-Guided Estimation, that connects natural, psychological, and social scientific inquiry. Presenting quantitative methods in the behavioral sciences as at once successful and regulated by the (...) world, the book will engage philosophers of science, historians of science, sociologists of science, and scientists interested in the foundations of their own disciplines. Part I introduces measured realism beginning with a novel realist theory of measurement (Population-Guided Estimation, or PGE). It examines two other versions of scientific realism — minimal (Hacking) and robust (Boyd, Putnam, and Newton-Smith) — and advances measured realism as best supported by the evidence in the behavioral sciences. It also critically evaluates the anti-realist arguments of van Fraassen, Laudan, and Fine. Part II formulates and develops a version of epistemological naturalism most appropriate to measured realism. Drawing upon the realist theory of measurement developed earlier, it favorably appraises a variety of statistical methods in the behavioral sciences against selected criticisms. It concludes that traditional, narrative methods in the behavioral and social sciences are unreliable by the measures of epistemological naturalism. (shrink)

This thesis attempts to show that Georg Lukacs' Marxist theory of realism is best understood, not as a self sufficient body of theory, but in the context of his pre- Marxist theory of literature and his,role in the Communist movement, A comparison of the theory expounded in "Die Seele and die Fonaen" and "Die Theorie des Romans" with the main positions of "Geschichte und Kiassenbewusstsein" reveals that it was remarkably easy for Lukacs to accommodate (...) his literary theory within the newly-acquired philosophy. An examination of Lukacs' career shows that his move to Marxism was motivated by a search for the practical instrument to implement the ideal which was the mainspring behind both his own life and, in his theory, all great literature, namely, the classical ideal of harmony. The resulting change in emphasis from aesthetics to political action led, in the thirties, to the attempt to synthesize both in a cultural campaign. Political pressure, combined with the genuine belief that the excesses of Stalinism were the acceptable price of resistance to the overriding threat of fascism, resulted in the employment of a rigid determinism, deplored ill others, which was incompatible with the core of his understanding of literary realism. The creation of realism was, however, for both the pre- Marxist and the Marxist Lukacs, ultimately inexplicable in materialist terms. (shrink)

Scientific realism is the view that our best scientific theories give approximately true descriptions of both observable and unobservable aspects of a mind-independent world. Debates between realists and their critics are at the very heart of the philosophy of science. Anjan Chakravartty traces the contemporary evolution of realism by examining the most promising strategies adopted by its proponents in response to the forceful challenges of antirealist sceptics, resulting in a positive proposal for scientific realism today. He (...) examines the core principles of the realist position, and sheds light on topics including the varieties of metaphysical commitment required, and the nature of the conflict between realism and its empiricist rivals. By illuminating the connections between realist interpretations of scientific knowledge and the metaphysical foundations supporting them, his book offers a compelling vision of how realism can provide an internally consistent and coherent account of scientific knowledge.

SummaryThis paper addresses the question of what scientific realism implies and what it does not when it is articulated so as to provide the best defense against plausible philosophical alternatives. A summary is presented of “abductive” arguments for scientific realism, and of the epistemological and semantic conceptions upon which they depend. Taking these arguments to be the best current defense of realism, it is inquired what, in the sense just mentioned, realism implies and what (...) it does not. It is concluded that realism implies the strong rejection of epistemological foundationalism, a non‐Humean conception of causation and of explanation, and a causal rather than conceptual account of the unity of natural definitions. It is denied that realism implies bivalence or the existence of one true theory, one preferred vocabulary or one distinctly privileged science. It is further denied that realism implies that there are no unrecognized conventional aspects to scientific theorizing and it is denied that realism implies that scientists routinely do good experimental metaphysics.

In An Introduction to Metaphysics Heidegger asserted that “it wasnot German idealism that collapsed; rather, the age was no longer strong enough to sustain the greatness, breadth, and originality of that spiritual world, i.e., truly to realize it”. He was at this point launchinginto one of the major themes of his later work: the “darkening of the world” in the form of the materialism and “demonism” typified by the antitheses of the USSR and the USA, a polarity of seeming opposites (...) obscuring an underlying fundamental similarity. This was the modernist faith of both cultures in the power of science to solve all of the problems that have plagued humanity for untold centuries, a faith in the power of science to tell us the absolute truth about the nature of reality. In 1955 Heidegger also characterized science and technology in “The Question Concerning Technology” as an “enframing”, a particular dominant interpretation of reality dependent on the interest of control and which conceals far more than it reveals. For one thing, “the essence of technology isin a lofty sense ambiguous. Such ambiguity points to the mystery of all revealing, i.e., of truth”. Although enframing “lets man endure,” only art as the successor of philosophy transcends techne by allowing us to see that “the essence of technologyis nothing technological”. Much earlier, in Being and Time, he gave his first sustained account of science as the interpretationof reality driven by technological interests, and spoke of Being as the “transcendens” lying beyond “every possible character which an entity can possess” [p. 38]. It remains debatable whether this characterization of Being survived into Heidegger's later period, but despite his nostalgia for the spirituality of the early nineteenth century, the role of Beingin these earlier works might best be explained as some kind of realism.

Does a hard-headed realist approach to international politics necessarily involve scepticism towards progressive foreign policy initiatives and global reform? Should proponents of realism always be seen as morally complacent and politically combative? In this major reconsideration of the main figures of international political theory, Bill Scheuerman challenges conventional wisdom to reveal a neglected tradition of progressive realism with much to contribute to contemporary debates about international policy-making and world government. Far from seeing international reform as well-meaning but (...) potentially irresponsible idealism, progressive realists like E.H. Carr, John Herz, Hans J. Morgenthau, and Reinhold Niebuhr developed forward-looking ideas which offer an indispensable corrective to many presently influential views about global politics. Progressive realism, Scheuerman argues, offers a compelling and provocative vision of radical global change which - when properly interpreted, can help buttress current efforts to address the most pressing international issues. After recovering key subterranean strands in mid-twentieth century realism, Scheuerman underscores their relevance to contemporary international theory. Criticizing more recent realists for abandoning their tradition's best insights, he also demonstrates that reform-minded international theories - including versions of cosmopolitanism, constructivism, the English School, liberalism, and republicanism - could all benefit from taking Progressive Realism seriously. A major contribution both to the history of international relations and contemporary debates in international theory, The Realist Case for Global Reform concludes by considering how progressive realism informs the foreign policies of US President Barack Obama.

A realist Daoism is best illustrated through contrasting with something less robust. Chad Hansen’s Daoism may be understood as a linguistic constructivism and is thus a good candidate. I challenge his interpretation of the Zhuang-Zi and respond with a realist understanding of daos. The resultant realist Daoism is to be understood given a Daoist realism from Lao Zi’s Dao-De-Jing, whose realist flavour is constituted by some dao sometimes, if not always, outrunning us. The present paper thus situates Zhuang (...) Zi better as inheriting Daoism from Lao Zi, contributing to classical Daoism with a relativity that is realist. I submit a sinological hypothesis about wu-wei, from a theory of wei that grapples with the two senses of the Chinese word: one about doing, another fictitiousness. I venture further a philosophical hypothesis that in a realist Daoism, an artificiality that is bad, such as hypocrisy, differs from some other artificiality that though involves pretence is of real Daoist value. The present Daoist realism comes with a Dao externalism, illustrated with a wanderer wandering in nature, when their paths outrun them. Even with a dao, instead of the Dao, the externalism enables an artist’s performance in their own style having a success condition that also outruns them, such that one always could have done better. A humanism that entails the possibility of an aesthetic competence embodying the Dao is explored. (shrink)

Critical realism is a frequently mentioned, but not very well-known, late nineteenth-/early twentieth-century philosophical tradition. Having its roots in Kantian epistemology, critical realism is best characterized as a revisionist approach toward the original Kantian doctrine. Its most outstanding thesis is the idea that Kantian things-in-themselves are knowable. This idea was—at least implicitly—suggested by thinkers such as Alois Riehl, Wilhelm Wundt, and Oswald Külpe. Interestingly enough, the philosophical position of the early Moritz Schlick stands in the critical realist (...) tradition as well. As will be outlined in the course of this paper, both Schlick’s magnum opus General Theory of Knowledge (1918) and his seminal Space and Time in Contemporary Physics (1917) are based on the assumption that the objects of science are relations and that relations have the status of Kantian things-in-themselves. By way of conclusion, I shall point out that this— more or less directly—leads to the current debate over ‘structural’ realism. (shrink)

In this dissertation, I examine a view called ‘Epistemic Structural Realism’, which holds that we can, at best, have knowledge of the structure of the physical world. Put crudely, we can know physical objects only to the extent that they are nodes in a structure. In the spirit of Occam’s razor, I argue that, given certain minimal assumptions, epistemic structural realism provides a viable and reasonable scientific realist position that is less vulnerable to anti-realist arguments than any (...) of its rivals.

Non-Realist Cognitivism is a meta-ethical theory that is supposedly objectionably unclear. Recently, Farbod Akhlaghi (2022) has provided a novel exposition of Parfit’s Non-Realist Cognitivism that employs truthmaker theory to clarify it. He illustrates that such clarification leads the non-realist cognitivist into a dilemma: either the theory has to accept truthmaker maximalism, rendering the theory inconsistent, or it has to let go of truthmaking altogether. He also attempts to undercut a “partners-in-innocence” strategy that the non-realist cognitivist utilizes (...) to motivate the key assumption of Non-Realist Cognitivism: that normative truths are truthmaker gaps. In this paper, we do three things in reply to Akhlaghi. First, we show how most of his attempts to disqualify candidate partners-in-innocence fail, or at best miss the point. Second, we provide a case for a partner-in-innocence Akhlaghi never covers, though inadvertently mentions. Third, we outline how the non-realist cognitivist could reply to Akhlaghi’s dilemma in a way that allows Non-Realist Cognitivism to come out unscathed. (shrink)

REN PASSMORE wrote his assessment of British moral philosophy, he lamented that the fifty years which :had elapsed since 1900 had produced nothing beitter than so many variations on utilitarianism. Equally, a lament seems in order over the ourrent state of epistemology. After so many years of grappling with the problem of v,aJidating epistemo1log~cail!l'eailism-consider, for example, the American scene during the first severail decades of this century: Roy Wood Sellars et al. announcing the "new realism '' and George Santayana et al. announcing,the "critical realism "one might have hoped for 1 an oiutcome more reassuring than Hie current £deistic realism. But if the fideism disappoints, its rationalizations fascinate. Take, for examp1e, the trio o.f books discussed herein. They undertake a common project: to forge a raitionaJ justification for realism. They shave other features, not so 1audatory, especiaUy :a merely fideis:tic ioommitment to what might best be deseribed as generic realism, which finally evaporaites into 631 RAYMOND DENNEHY idealism. The mo,sit thait the authors can muster on behalf of realism amounts: to no more than this: " Something (what, we don't know) must e.rist outside our minds heearuse we aict on that premise with considemhle success, not only in daily life hut in scientific prructice, aillld a~l the theories used to explruin it aDJd its successes form a logieally coherent whoJe." In other wo11ds, whait these "defenses'' of rerulism offer is a pragmatic representationalism, organized and ultimaitiely vindi!caited by the ideaJist criterion of coherence and der,iving overai11 inspiration from a blind faith in e~tmmental reality. The tip-off,fa,in the books' titles: Contextual Real-ism, The Many Fa(')es of Realism, and Varieties of Realism. How can you taJk about the "contexts," " v;arieties,'' and "many faces " of realism if__,espreiciaJJy by your own admiss:ion-you cannot identify 11eaJ,ity itself? The answer is found in fideism: you want to affirm extramentaJ reality, even though y;ou find it impossible to justify 1that affirmation,rationaHy. So, in a flush. of ega,1itarian fervur, you aooept au plausible claimants to the title of " reality "; and being unabJ:e to say that any one c~aim­ ant is more or ~ess 11eal than any other, you hope to bring matters to a happy conclusion by apperuling to "varieties," "con- :te:xJts," and "many faces" of rea1ity. Hut the imperatives of life and thought maroe,a harmoniza-,tion of ail1l these " realities'' inevitable if anything resembling tl'IUe and false assertions is to he sav;ed. If, for example, common sense tells us that the11e 1a11e,ice cubes and scienee teHs us that the11e are only indeterminate mass particles, we will want to know how these 1 asse11tions can both be true. Clearly, the V'enerahle correspondence criterion of truth won't do here, is:ince we are fruoed with two oompeting objects of correspondence. It thus becomes necessary to enlist :the aid of the pragmatic theory of tmth to deoide which of the " realities " wil,l be designated " xeal '' in a part:iou~ar set of circumstances. Anticipating PiUtnam's examp~e, we ma.y then say that ice cubes~ and pink ones aJt that__,are real when we wish to mix drinks and that iDJdeterminate mass particles,a~11e reail when we wish UNREAL REALISM 633 to produce a scientific ruoom.mt of the phenomenon caHed " ice cubes." Still,.antil(Jipating Schlagel, not even pragmatism carries us far enough because it depends on knowing which resuJtis are felicitous. We thus turn fo the cohe11ence theory of tmth as our final court of... (shrink)

Structural realists of nearly all stripes endorse the structural continuity claim. Roughly speaking, this is the claim that the structure of successful scientific theories survives theory change because it has latched on to the structure of the world. In this paper I elaborate, elucidate and modify the structural continuity claim and its associated argument. I do so without presupposing a particular conception of structure that favours this or that kind of structural realism. Instead I focus on how structural (...) realists can best account for the neutrally formulated historical facts. The result, I hope, crystallises some of the shared commitments, desiderata and limits of structural realists. (shrink)

Worrall :99–124, 1989) famously claimed that structural realism is the best of both worlds; it enables one to endorse the best arguments for scientific realism and antirealism. In this paper, I argue that structural realism also enables one to combine two other seemingly inconsistent positions: realism and pluralism. Indeed, the very features which form the basis of the structural realist’s reply to the problem of theory change may be applied synchronically to allow for (...) a pluralist structural realism. The resulting position incorporates a robust variety of scientific pluralism unavailable to the traditional realist and thereby allows the structural realist to take seriously the pluralism apparent in scientific practice.

It is widely believed that science is in the business of finding out what the world is really like. The philosophical version of this belief is scientific realism -- a doctrine about science that tells us that we ought to believe that the best theories in science are true, and that the world is occupied with the objects that those theories contain. If scientific realism was not correct, the argument goes, the incredible success of science would be (...) a miracle. The best explanation for the success of science however, is not that it is a miracle, but that scientific theories are true. This argument is an instance of inference to the best explanation, or IBE. Skeptics have questioned why scientific success must imply its truth given that there are so many abandoned, false scientific theories in the history of science that were nevertheless successful. One of the controversies in the debate between scientific realists and anti-realists surrounds the legitimacy of reasoning in accordance with IBE. Realists need IBE to be a justified and reliable guide to truth. In this compilation thesis, I address various questions related to IBE and scientific realism. Paper 1 argues that scientific realism without IBE loses too much of its epistemic optimism, and that it in some contexts even becomes more pessimistic than the most prominent rival philosophical doctrine about science -- constructive empiricism. To avoid deflating realism, I argue, a defense of IBE is necessary. Paper 2 addresses whether methodological similarities between science and metaphysics force scientific realists to also be realists with respect to metaphysics. If IBE is legitimate, it should not only be valid in science, but also in metaphysics, effectively inflating the ontology that scientific realists are rationally bound to accept. I argue against this conclusion. Paper 3 offers a proof of concept regarding a novel way to justify inferences to unobservable objects. Paper 4 establishes a novel critique of non-probabilistic versions of IBE in scientific realism. (shrink)

There are only three distinct temporal relationships between art and theory: either the development of new events precedes theory, or both develop side by side, or theory anticipates the appearance of the new artistic current. This temporal relationship is, to some degree, fundamental in the relationship between both phenomena. If one is dealing with the first case, theories of art serve only to redress a balance. The art-theory introduces nothing in any way new; it serves only (...) to explain an artistic process which has already flowered. At most, largely thanks to critical studies, it helps the public understand the new works unexpectedly arising in the field of art, and plays the role of popularizing these new works, in the best sense of the word.

Embodied, embedded, enactive, and extended theorists do not typically focus on the ontological frameworks in which they develop their theories. One exception is 4E theories that embrace New Mechanism. In this paper, we endorse the New Mechanist’s general turn to ontology, but argue that their ontology is not the best on the market for 4E theories. Instead, we advocate for a different ontology: causal powers realism. Causal powers realism posits that psychological manifestations are the product of mental (...) powers, and that mental powers are empirically-discoverable features of individuals that account for the causal work those individuals do. We contend that causal powers realism provides a unifying framework for the central commitments of 4E theories, as well as additional resources for theorizing in a 4E framework. And while New Mechanism offers some of these resources as well, we argue that causal powers realism is ultimately the better of the two. (shrink)
