Scientific Realism

Review of Seungbae Park “Embracing scientific realism”. Springer, 2022 .

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of judgment "propagates" from (...) the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism and scientific realism. (shrink)

First, I show that the semantic thesis of scientific realism may be relaxed significantly—to allow that some scientific discourse is not truth-valued—without making any concessions concerning the epistemic or methodological theses which lie at realism’s core. Second, I illustrate how relaxing the semantic thesis allows realists to avoid positing abstract entities and to fend off objections to the ‘no miracles’ argument from positions such as cognitive instrumentalism. Third, I argue that the semantic thesis of scientific realism should be relaxed, because (...) it is possible for scientific statements to be partially true, and hence approximately true, without being false.

I explore the process of changes in the observability of entities and objects in science and how such changes impact two key issues in the scientific realism debate: the claim that predictively successful elements of past science are retained in current scientific theories, and the inductive defense of a specific version of inference to the best explanation with respect to unobservables. I provide a case-study of the discovery of radium by Marie Curie in order to show that the observability of (...) some entities can change and that such changes are relevant for arguments seeking to establish the reliability of success-to-truth inferences with respect to unobservables.

Cosmovision is a term that should mean a set of foundations from which emerges a systemic understanding of the Universe, its components as life, the world we live in, nature, the human phenomenon, and their relationships. It is, therefore, a field of analytical philosophy fed by the sciences, whose objective is this aggregated and epistemologically sustainable knowledge about everything that we are and contain, that surrounds us, and that relates to us in any way. It is something as old as (...) human thought and, in addition to using elements of scientific cosmology, it encompasses everything in philosophy and science that refers to the universe and life. A cosmovision is not a set of ideas, hypotheses, and assumptions but a system based on observation, analysis, evidence, and demonstration. No cosmovision intends to define, establish, propose but only understand, analyze and interpret. Each of us builds and transports his cosmovision throughout life, without establishing forms, as a background for our thinking and behavior. Linguistically, the term “cosmovision” would derive from the German, equivalent to the concept of “ Weltanschauung,” as used by several philosophers. However, this linguistic relationship is not applicable because it contradicts what we propose as a cosmovision. This German word refers to a pre-logical or proto- experimental vision of reality, with an intuitive context and far from critical knowledge still non-existent at the time of its formulation. Undoubtedly, cosmovisions, in the sense in which we understand them, house and use these proto-experimental or pre-logical elements that include history, the collective unconscious, and all the archetypes we carry. However, in the concept that we apply here, the cosmovision goes far beyond this content, firstly by constantly submitting it to present critical thinking, and finally by making the analytic experience ( and not the thought itself or intuition) its actual universe. António Lopes expose the breadth of this content: -/- "Cosmovisions are not the product of thought. They do not spring from the simple desire to know. The apprehension of reality is an important moment in its configuration, but, nevertheless, it is only one. It comes from the vital conduct, from the experience of life's evaluation, from the structure of our psychic totality. The elevation of life to consciousness in the knowledge of reality, in the valuation, and in the volitional reality is the slow and arduous work that humanity has done in the development of the conceptions of life. (W. Dilthey, 1992 [1911]: 120)”(1) -/- In this work, we seek to outline a cosmovision based on the realities that science offers today. We do not propose, at any time, to do science; or theorize philosophy, but we will always seek to be supported by them or, at least, protected by them from the cognitive distortions that we usually carry. ________________________________________________ (1) Lopes , Antonio – “ Weltanschauung (Cosmovision)” (2009 ) in Carlos Ceia's E-Dictionary of Literary Terms. -/- .

In this innovative book, Hasok Chang constructs a philosophy of science for 'realistic people' interested in understanding and promoting the actual practices of inquiry in science and other knowledge-focused areas of life. Inspired by pragmatist philosophy, he reconceives the very notions of reality and truth on the basis of his concept of the 'operational coherence' of epistemic activities, and offers new pragmatist conceptions of truth and reality as operational ideals achievable in actual scientific practice. Rejecting the version of scientific realism (...) that is concerned with claiming that our theories correspond to an ultimate reality, he proposes instead an 'activist realism': a commitment to do all that we can actually do to improve our knowledge of realities. His book will appeal to scholars and students in philosophy, science and the history of science, and all who are concerned about the place of science and empirical truth in society. (shrink)

Philosophers of science often assume that logically equivalent theories are theoretically equivalent. I argue that two theses, anti-exceptionalism about logic (which says, roughly, that logic is not a priori, that it is revisable, and that it is not special or set apart from other human inquiry) and logical realism (which says, roughly, that differences in logic reflect genuine metaphysical differences in the world), make trouble for both this commitment and the closely related commitment to theories being closed under logical consequence. (...) I provide three arguments. The first two show that anti-exceptionalism about logic provides an epistemic challenge to both the closure and the equivalence claims; the third shows that logical realism provides a metaphysical challenge to both the closure and the equivalence claims. Along the way, I show that there are important methodological upshots for metaphysicians and philosophers of logic. In particular, there are lessons to be drawn about certain conceptions of naturalism as constraining the possibilities for metaphysics and the philosophy of logic. (shrink)

In his chapter in this volume, Christopher Pincock develops an argument for scientific realism based on scientific understanding, and he argues that Giere’s (2006) and my (2017, 2020) commitment to the context-dependence of scientific understanding or knowledge renders our views unable to account for an essential step in how scientists come to know. Meanwhile, in my chapter in this volume, I motivate a view that I call "causal pattern realism." In this response to Pincock's chapter, I will sketch a revised (...) version of Pincock’s argument for realism that is consistent with causal pattern realism. Then I will respond to Pincock’s concern that the context-dependence of understanding on my view would interfere with the scientific community’s ability to extrapolate from specific experimental and observational contexts as needed to develop knowledge. My goal is not to convince anyone to be a causal pattern realist but rather to create the space for such a view, taking into account the concerns motivating Pincock. (shrink)

The present paper revisits the debate between realists about gravitational energy in GR and anti-realists/eliminativists. I re-assess the arguments underpinning Hoefer’s seminal eliminativist stance, and those of their realist detractors’ responses. A more circumspect reading of the former is proffered that discloses where the so far not fully appreciated, real challenges lie for realism about gravitational energy. I subsequently turn to Lam and Read’s recent proposals for such a realism. Their arguments are critically examined. Special attention is devoted to the (...) adequacy of Read’s appeals to functionalism, imported from the philosophy of mind. (shrink)

This book provides philosophers of science with new theoretical resources for making their own contributions to the scientific realism debate. Readers will encounter old and new arguments for and against scientific realism. They will also be given useful tips for how to provide influential formulations of scientific realism and antirealism. Finally, they will see how scientific realism relates to scientific progress, scientific understanding, mathematical realism, and scientific practice.

Many philosophers adopt methods that emulate those of the natural sciences. For them, this position, which they call naturalism, defines the indispensable set of starting points for fruitful debate in various areas. In spite of this consensus, however, little is ever said about the way naturalism depends on the primary idea of nature. If we understand this dependency of naturalism on underlying accounts of nature, we would be in a better position to recognize and evaluate different kinds of naturalism. In (...) this research monograph, I undertake a sustained study of the concept of nature to answer this need. I examine in detail how conceptual, historical, and scientific constraints affect, and are in turn affected by, the concept of nature in various domains of philosophy, and I relate the conceptual framework of scientific inquiry back to the lived experience that is proper to everyday self-understanding. The method I use is conceptual analysis. I begin with an evaluation and justification of this method, and then present the fundamental idea that forms the backbone of the entire book, namely the idea of complexification of concepts in the course of history. I present the four main views on nature that have dominated Western thought: the dynamic view, related primarily to Aristotle’s approach, the mechanistic view, the Romantic view, and the evolutionary view. From here, I engage in a detailed inquiry into the fundamental ideas of explanation and causation, defending a pluralist account for both. I then examine carefully the intricate relation between things and the meaning of the words we use to describe them. I show how we can acknowledge the emergence of complex properties from simpler ones within an overall evolutionary view of nature. I also explore how concepts concerning the nature of things are related to values. The final chapter deals with an objection that arises from those who claim that the empirical method is the only one available for our knowledge of nature. I show that the value of conceptual analysis, as used in this book, remains unharmed by this objection. We need to accept that, in the course of history, the concept of nature has become complexified, multilayered, and increasingly loaded with internal tension because of its many relations to different areas of our conceptual scheme.

Decades of debate about scientific realism notwithstanding, we find ourselves bemused by what different philosophers appear to think it is, exactly. Does it require any sort of belief in relation to scientific theories and, if so, what sort? Is it rather typified by a certain understanding of the rationality of such beliefs? In the following dialogue we explore these questions in hopes of clarifying some convictions about what scientific realism is, and what it could or should be. En route, we (...) encounter some profoundly divergent conceptions of the nature of science and of philosophy. (shrink)

Explanatory elucidation occurs when a theory has one or more of its assumptions explained by another independently successful theory. Because explanatory elucidation springs from independently supported theories, it improves the credibility of the assumptions it casts light on, hence its relevance for realists. But cases can be pointed to where explanatory elucidation has badly failed to identify truthful components. One way to address this challenge is by trying to find additional epistemic support for seemingly meritorious theory-parts. Resource in this regard, (...) I suggest, include some specific lines of probing that regularly turn up against theories in mature scientific disciplines. Together with explanatory elucidation, those lines single out, in diachronic fashion, theory components worthy of realist commitment, or so I argue. (shrink)

This article explores and attempts to resolve some issues that arise when at stake is the need to harmonize philosophical hermeneutics with a kind of realist philosophy of science. The author takes issue with established position in the realism-antirealism controversy. Interventionism is criticized for a residual Cartesian dualism. Cognitive relativism is debated by developing a concept of situated transcendence in the constitution of objects of inquiry. Non-behaviorist arguments against scheme-content dualism are advanced that appeal to context- sensitive theory of meaning. (...) Social constructivism is rejected for the hypostatization of epistemic positions. The article suggests a model of the constitution of meaning. It undertakes an attempt at demonstrating how the integration of this model in a hermeneutic philosophy of science leads to realism without epistemological representationalism, foundationalism, and cognitive essentialism. The article is oriented toward a new dialogue between hermeneutic phenomenology and a holistic epistemology. (shrink)

In this paper we explore Ronald N. Giere’s contributions to the scientific realism debate. After outlining some of his general views on the philosophy of science, we locate his contributions within the traditional scientific realism debate. We argue that Giere’s scientific perspectivism is best seen as a form of carte blanche realism, that is: a view according to which science is a practice aiming at truth, and can warrantably claim to have attained it, to a certain degree; however, it does (...) not place our confidence invariably in some specific feature of scientific representations. (shrink)

I provide a critical review of Moti Mizrahi's The Relativity of Theory, expounding on the book's strengths and then providing an extended argument that Mizrahi mischaracterizes the epistemic attitude of concern to antirealism about science as well as the practical stakes involved in adopting the antirealist position.

According to scientific realists, the predictive success of mature theories provides a strong epistemic basis for thinking that such theories are approximately true. However, we know that many theories once regarded as well-confirmed and predictively successful were eventually replaced with successor theories, and some claim this undermines the epistemic confidence we should have in the approximate truth of current science. Selective scientific realists in turn argue that if one can show that the predictive success of some rejected theory T is (...) a function of theoretical claims consistent with current science, then T’s failure doesn’t undermine the claim that current successful theories are approximately true. As such, Selective Scientific Realism (SSR) can be tested through historical examples. Showing that the predictive success of a failed theory is the result of theoretical features later rejected provides a counterexample to SSR. Conversely, SSR is supported if its explanation of the predictive success of failed theories--namely, that the factors which lead to predictive success in the failed theory survive in the successor theory--is able to handle a wide array of historical cases.

In this paper, I argue that what counts as the proper function of a trait is a matter of the de facto perspective that the biological system, itself, possesses on what counts as proper functioning for that trait. Unlike non-perspectival accounts, internal perspectivalism does not succumb to generality problems. But unlike external perspectivalism, internal perspectivalism can provide a fully naturalistic, mind-independent grounding of proper function and natural norms. The attribution of perspectives to biological systems is intended to be neither metaphorical (...) nor anthropomorphic: I do not mean to imply that such systems thereby must possess agency, cognition, intentions, concepts, or mental or psychological states. Instead, such systems provide the grounding for norms of performance when they internally enforce their own standard of (i.e., their own perspective on) what constitutes proper functioning or malfunctioning. By operating with a fixed, determinate level of generality, such systems provide the basis for an account of proper function that is immune to generality problems. (shrink)

Le réalisme scientifique occupe une place centrale dans le système philosophique de Mario Bunge. Au cœur de cette thèse, on trouve l’affirmation selon laquelle nous pouvons connaître le monde partiellement. Il s’ensuit que les théories scientifiques ne sont pas totalement vraies ou totalement fausses, mais plutôt partiellement vraies et partiellement fausses. Ces énoncés sur la connaissance scientifique, à première vue plausible pour quiconque est familier avec la pratique scientifique, demandent néanmoins à être clarifiés, précisés et, ultimement, à être inclus dans (...) un cadre théorique plus large et rigoureux. Depuis ses toutes premières publications sur ces questions et jusqu’à récemment, Mario Bunge n’a cessé d’interpeller les philosophes afin qu’ils développent une théorie, au sens propre du terme, de la vérité partielle afin de clarifier les enjeux épistémologiques liés au réalisme scientifique. Bunge a lui-même proposé plusieurs parties de cette théorie au fil des années, mais aucune de ces propositions ne l’a satisfait pleinement et la construction de cette théorie demeure un problème entier. Dans ce texte, nous passerons rapidement en revue certaines des approches proposées par Bunge dans ses publications et nous esquisserons certaines pistes qui devraient servir à tout le moins de desiderata pour la construction d’une théorie de la vérité partielle.

Most contemporary proponents of scientific realism advocate some form of selective realism. One of the most prominent variants is the working posits view, which claims that the essential propositions of a successful theory are those that are involved in the actual derivations of predictions. In this paper, I offer a systematic examination of this view, surveying no fewer than six competing interpretations of it. I argue, however, that none is satisfactory. A general reason to reject the working posits view is (...) that it focuses on individual successful derivations, as opposed to the empirical success of a theory as a whole. In response to this, I suggest an alternative positive view, which regards as essential those theoretical posits which “unify” a diverse or large collection of other posits. (shrink)

The notion of objectivity is ambiguous. A distinction is made between three primary notions of objectivity: ontological objectivity, the objectivity of truth and epistemic objectivity. It is suggested that a realist may explain the relationship between the three notions by saying that use of epistemically objective methods stands the best chance of leading to the objective truth about the objective world.

Review of The Routledge Handbook of Scientific Realism by Juha Saatsi (ed.).

This is a comment on Professor Holm Tetens' paper, 'Scientific Objectivity with a Human Face'.

This is a response to Dragan Jakowljewitsch's 'The Successes of Science and Scientific-Theoretical Realism: A Less Than Direct Connection'.

This is certainly true. Simulationists and experimentalists face equally relevant challenges when it comes to establishing that the results of their simulation or experiment are informative about the real world. But it is one thing to point this fact out, and it is another to understand how those challenges are overcome, under differing circumstances, and in varying contexts. It is here that Marcel Boumans’ contribution becomes especially valuable. He presents an example from economics in which a mathematical model performs the (...) role, not of a representational entity, but of a data sensor. Boumans argues, and I concur, that the manner in which such models are assessed is particularly interesting. They cannot be assessed merely by being confronted with facts about the world, since these models are themselves used in generating the relevant data about the phenomena in question. The relevant strategy for assessing these models is calibration. In other words, rather than being held side by side with the relevant bit of the world, the models are held up against other instruments that are antecedently believed to be reliable sources of data.

My current opinion is that the selective realist is in a strong position vis-à-vis the historical challenges. Certainly the realist needs to invoke some careful criteria for realist commitment, and various nuances concerning the nature of her epistemic commitment, and this may raise the ‘death by a thousand qualifications’ question mark. But the concern is unfounded: the qualifications are all independently motivated, and indeed necessary given the philosophical complexity. Qualifications are to be welcomed here; often the truth is far from (...) simple! (shrink)

Many philosophers take mind-independence to be criterial for realism about kinds. This is problematic when it comes to psychological and social kinds, which are unavoidably mind-dependent. But reflection on the case of artificial or synthetic kinds shows that the criterion of mind-independence needs to be qualified in certain ways. However, I argue that none of the usual variants on the criterion of mind-dependence is capable of distinguishing real or natural kinds from non-real kinds. Although there is a way of modifying (...) the criterion of mind-independence in such a way as to rule in artificial kinds but rule out psychological and social kinds, this does not make the latter non-real. I conclude by proposing a different way of distinguishing real from non-real kinds, which does not involve mind-independence and does not necessarily exclude psychological and social kinds. (shrink)

In a recent volume of this journal Saatsi [Saatsi, J.. Reconsidering the Fresnel–Maxwell theory shift: How the realist can have her cake and EAT it too. Studies in History and Philosophy of Science, 36, 509–536.] suggests that we adopt an approach where we explain phenomena reductively, by properties that are described via their nomological roles. These properties are conceived of as higher-order multiply realisable properties. Such properties are however not causally efficacious independent of their causal basis. Therefore Saatsi has left (...) it open what kind of explanatory work these properties could possibly do.Keywords: Realism; Multi realisability; Structuralism; Semirealism; Eclectic realism; Higher-order propertiess.

Turner [The past vs. the tiny: Historical science and the abductive arguments for realism. Studies in History and Philosophy of Science 35A 1] claims that the arguments in favor of realism do not support with the same force both classes of realism, since they supply stronger reasons for experimental realism than for historical realism. I would like to make two comments, which should be seen as amplifications inspired by his proposal, rather than as a criticism. First, it is important to (...) highlight that Turner’s distinction between ‘tiny’ and ‘past unobservables’ is neither excluding nor exhaustive. Second, even if we agreed with everything that Turner says regarding the arguments for realism and their relative weight in order to justify the experimental or historical version, there is an aspect that Turner does not consider and that renders historical realism less problematic than experimental realism.Keywords: Scientific realism; Derek Turner; Rom Harré; Historical science; Ian Hacking.

First published in 1975 by Leeds Books Ltd., this second, revised edition adds only a short, twelve page Postscript and an Index. The former replies to reviews of the original edition by clarifying the use of two key terms, by commenting on its principal weaknesses, and by indicating the direction of further work required by the position advocated.

I argue that critical realists think pretty much what Tukka Kaidesoja says that he himself thinks, but also that Kaidesoja’s objections to the views that he attributes to critical realists are not persuasive.

In this paper, I am concerned with the possibility of applying an abductive strategy in founding ethical realism. First, I criticize Harman’s position, according to which abduction, though useful for founding scientific realism, does not serve to found ethical realism. Secondly, I examine Sturgeon’s critique, according to which distinctively moral facts do constitute the best explanations of the moral evidence. Finally,I conclude that Sturgeon is right in as far as the ontological status of moral properties is concerned but his answer (...) to Harman’s point is not properly developed. (shrink)

The paper discusses Giere’s perspectivism in philosophy of science. Giere is certainly right in judging that, even within perspectives, the strongest possible conclusion is that some model provides a good but never perfect fit to aspects of the world, but its agency-laden “modelism” and realistic instrumentalism should be extended to a comprehensive general perspectivist and “indirect” realistic epistemology and embed it in an anthropology proper of the man as “flexible multiple human being”. Scheme-interpretations and specific perspectives are necessary for any (...) cognition in any science—natural and social, but also for everyday conceptions, modeling and practical acting as well as in philosophy and philosophy of science. (shrink)

Chapter I describes diachronic realism and shows why it is a version of what is called 'metaphysical realism'. Consequently, I argue that recent claims that 'metaphysical realism' is incoherent are unfounded. Chapter II argues that certain anti-realist positions involve an insufficient treatment of 'meaning' and 'reference' for theoretical terms. I review much of the current work on theories of reference and show that these incommensurability positions are bankrupt given either of the two most promising theories of reference. Chapter III argues (...) that certain methodological factors are the main considerations in historical cases of theory choice, and can warrant rational belief in a theory if it has achieved a sufficient level of virtues. Chapter IV defends the intuition that a realist interpretation of scientific theories explains their success by expanding the concepts of 'truth' and 'approximate truth'. I introduce the notions of truthlikeness and being on the right track to distinguish theories that were at least partially theoretically correct, from theories that were only successful in that they correctly organized experimental data. I use these notions with my diachronic approach to analyze two important historical examples. (shrink)

L’attitude réaliste constitue de prime abord la posture du sens commun vis-à-vis de la science. Elle consiste à attribuer à la science l’objectif de décrire littéralement la réalité tout en lui reconnaissant la capacité, en vertu de ses méthodes, d’atteindre ce but. Si le réalisme scientifique apparait comme représentant le sens commun, il a dû, au courant du siècle dernier, s’ériger en véritable posture philosophique argumentée devant l’influence grandissante des différentes formes d’antiréalismes. Dans la mesure où la posture qu’un philosophe (...) adopte concernant la prétention des théories scientifiques à décrire le réel a un impact sur son traitement d’à peu près toutes les questions pertinentes de son champ de recherche, on peut dire que l’examen de la question du réalisme scientifique est recommandable à quiconque souhaite mener une réflexion philosophique à propos de l’entreprise scientifique. Cet article débute sur la présentation des thèses fondamentales du réalisme scientifique pour ensuite le distinguer des autres postures réalistes et antiréalistes qui s’y sont opposées. Une fois les contours de la notion de réalisme scientifique précisés, il sera question des principales considérations qui ont été mises de l’avant en sa faveur et en sa défaveur. Le principal argument positif pour le réalisme scientifique est l’argument dit de l’absence de miracle. Au-delà de cet argument, tous les arguments du réalisme scientifique sont issus de répliques aux différents défis antiréalistes qui lui ont été lancés depuis la seconde moitié du 20e siècle. Il s’agira donc, par la suite, de présenter ces différents défis en identifiant les postures qui s’en réclament ainsi que les principales stratégies employées par les réalistes pour tenter de les relever. À la lumière de ce qui aura été présenté, l’article se conclut en interrogeant la distance qui sépare véritablement le réalisme scientifique de l’antiréalisme dans leurs formes contemporaines.
