Scientific Realism

As the title suggests, David Landy’s Hume’s Science of Human Nature: Scientific Realism, Reason, and Substantial Explanation defends a staunchly realist interpretation of Hume on scientific explanation. Landy’s forward-looking view sees Hume’s methodology in the Treatise as anticipating developments much later in history. He gives Hume a Sellarsian update, making his philosophy of science more impactful and contemporary than previously thought. The motivation for his view is twofold. First, he wants to respond to the long line of Hume critics who (...) think his “science of human nature” is hardly science at all. According to this interpretive tradition, Hume’s “science” is merely the... (shrink)

Early Heidegger argues that a “homogenous space of nature” can be revealed by stripping away the intelligibility of Dasein's everyday world, a process he calls “deworlding.” Given this, some interpreters have suggested that Heidegger, despite not having worked out the details himself, is also committed to a notion of deworlded time. Such a “natural time” would amount to an endogenous sequentiality in which events are ordered independently of Dasein and the stand it takes on its being. I show that Heidegger (...) was indeed committed to such a temporal realism even though his treatment of these issues is somewhat scattered and pulled in different directions. In the course of my reconstruction, I renew an interpretation of Heidegger that stresses Dasein's thrownness into nature and I answer William Blattner's powerful interpretation of Heidegger as a failed temporal idealist who was unable to derive the sequentiality of ordinary time from Dasein's non-sequential originary temporality. Heidegger did not attempt to derive sequentiality; instead, he understood it as a built-in feature of the natural universe by which Dasein's activities are constrained. World-time turns out to be a co-production of Dasein's non-sequential originary temporality and the endogenous sequentiality of events in nature. (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.

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.

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.

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.

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.

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.

Conventional scientific realism is just the doctrine that our theoretical terms refer. Conventional antirealism denies, for various reasons, theoretical reference and takes theory to give us only information about the word of the perceptual where reference, it would appear, is secure. But reference fails for the perceptual every bit as much for the perceptual as for the theoretical, and for the same reason: the world is too complicated for us to succeed in attaching specific referents to our terms. That would (...) appear to leave us with a kind of latter day, representational idealism: All we have are representations. I argue that our representations tell us about an independent world without securing reference by showing that the world is very like the way it is represented in a range of different, often complementary modeling schemes. Though never exact, these representations are of something extra-representational because they present the world modally as going beyond what is represented explicitly. (shrink)

In practice theoretical terms are open-ended in not being attached to anything completely specific. This raises a problem for scientific realism: If there is no one completely specific kind of thing that might be in the extension of “atom”, what is it to claim that atoms exist? A realist’s solution is to say that in theoretical contexts of mature atom-theories there are things that play the role of atoms as characterized in that theory-context. The paper closes with a laundry list (...) of problems that this more careful statement of scientific realism still faces. (shrink)

Originally published in 1963. In an introductory chapter the author argues that philosophy ought to be more than the art of clarifying thought and that it should concern itself with outlining a scientifically plausible world view. Early chapters deal with phenomenalism and the reality of theoretical entities, and with the relation between the physical and biological sciences. Free will, issues of time and space and man’s place in nature are covered in later chapters.

In this paper I intend to reflect on the intellectual rationale underlying the origin of life scientific research efforts by reconsidering some of its conceptual premises and difficulties.

The main goal of this paper is to argue against Karl Rogers's attacks on realism in physics. Rogers argues that electrons do not exist independently of the relevant socio-technological process, but I show that such an assumption would make our best scientific theories incomprehensible. While the paper supports Rogers's attempts to refute positivism, it demonstrates that his own position is positivistic, and it corrects his overemphasis on the roles of technology and the experimenter. Rogers assumes that the founders of modern (...) science were simply mechanists, but I show how they were actually Platonic realists. Contrary to Rogers, realist faith in the fundamental unifying power of the laws of physics is shown to be reasonable, and any denial of this belief would imply that science is impossible. (shrink)

_Realism and the Aim of Science_ is one of the three volumes of Karl Popper’s _Postscript_ to the Logic of scientific Discovery. The _Postscript_ is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. _Realism and the Aim of Science_ is the first volume of the _Postcript_. Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can never prove, (...) or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. _Realism and the Aim of Science_ presents Popper’s mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science.

Our best sciences are frequently held to be one way, perhaps the optimal way, to learn about the world’s higher-level ontology and structure. I first argue that which scientific theory is “best” depends in part on our goals or purposes. As a result, it is theoretically possible to have two scientific theories of the same domain, where each theory is best for some goal, but where the two theories posit incompatible ontologies. That is, it is possible for us to have (...) goal-dependent pluralism in our scientific ontologies. This ontological pluralism arises simply from our inability to directly know the world’s objects, rather than any particular claims about our cognitive limits, values, or social structures. I then present two case studies in which this possibility actually occurs—one based on simulations and theoretical analyses of constructed causal systems, and one from actual scientific investigations into the proper ontology for ocean regions.

This book espouses a theory of scientific realism in which due weight is given to mathematics and logic. The authors argue that mathematics can be understood realistically if it is seen to be the study of universals, of properties and relations, of patterns and structures, the kinds of things which can be in several places at once. Taking this kind of scientific platonism as their point of departure, they show how the theory of universals can account for probability, laws of (...) nature, causation and explanation, and explore the consequences in all these fields. This will be an important book for all philosophers of science, logicians and metaphysicians, and their graduate students. The readership will also include those outside philosophy interested in the interrelationship of philosophy and science. (shrink)
