This paper discusses Hacking’s experimental realism and suggests a concept of realization to the issue about realism. I first rephrase Hacking’s experimental realism by reconstructing them into two theses and three arguments. Then I consider that Resnik’s objection to Hacking’s experimental realism. According to my understanding of Hacking’s experimental realism, Resnik’s objection failed because of his position at theory realism. Nevertheless, I think that there are still two problems about the (...) experimental aspect of the experimental realism. They are the pessimistic induction of experimental science argument and the combination of apparatus argument. I attempt to give a new perspective on the realism issue by proposing a set of related concepts containing categorization, model, and realization. Last, I show that this conceptual scheme can give a better solution of the two problems and cast a new light on the realism issue. (shrink)

On a purely epistemic understanding of experimental realism, manipulation affords a particularly robust kind of causal warrant, which is – like any other warrant – defeasible. I defend a version of Nancy Cartwright’s inference to the most likely cause, and I conclude that this minimally epistemic version of experimental realism is a coherent, adequate and plausible epistemology for science.

Traditional debates about scientific realism tend to focus on issues concerning scientific representation and de-emphasize issues concerning scientific intervention. Questions about the relation between theories and the world, the nature of scientific inference, and the structure of scientific explanations have occupied a central place in the realism debate, while questions about experimentation and technology have not. Ian Hacking's experimental realism attempts to reverse this trend by shifting the defense of realism away from representation to intervention. (...) Experimental realism, according to Hacking, does not require us to believe that our theories are true, nor does its defense depend on inference to the best explanation. For Hacking, the strongest proof for realism is that we can manipulate objects: 'So far as I'm concerned, if you can spray them, then they are real'. (shrink)

As Laudan and Fine show, and Boyd concedes, the attempt to infer the truth of scientific realism from the fact that it putatively provides the best explanation of the instrumental success of science is circular, since what is to be shown is precisely the legitimacy of such abductive inferences. Hacking's "experimental argument for scientific realism about entities" is one of the few arguments for scientific realism that purports to avoid this circularity. We argue that Hacking's argument (...) is as dependent on inference to the best explanation (IBE), and therefore as weak, as the other realist arguments. (shrink)

Experimental realism aims at striking a middle ground between scientific realism and anti-realism, between the success of experimental physics it would explain and the realism about scientific theories it would supplant. This middle ground reinstates the engineering idea that belief in scientific entities is justified on purely experimental grounds, without any commitment to scientific theories and laws. This paper argues that there is no defensible middle ground to be staked out when it comes (...) to justifying physicists' belief in colored quarks, and that experimental realism shifts, under analysis, into scientific realism.

THE CONVICTION that nature as ordinarily experienced is the manifestation of a deeper, more extensive physical reality is now commonplace. While Aristotle could believe that the visible qualities and substantial forms of the perceptual world correspond to the real natures of things, the advent of modern classical mechanics, incorporating the atomic theory, dispelled this notion. As in the ancient atomic theories of Leucippus and Democritus, the composition, motion, and qualitative changes of phenomena were attributed to the interaction of "insensible particles," (...) atoms or corpuscles, due to the influence of forces such as gravity, impact, and acceleration. Yet even in the Hellenistic world the search for "hidden causes" to explain observable phenomena was an established tradition, as indicated in this passage from the first century A.D. (shrink)

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

This is a revised edition of Hans Radder’s Habermas-inspired study of scientific experimentation and realism. The previous English edition (1988) has been out of print since 2004 (The book first appeared in Dutch in 1984). The author (together with the editors of the Boston Studies in the Philosophy of Science) has deemed it worthy of resuscitation. Perhaps it is. There are certainly a number of lasting elements of continuing interest, some of which indeed strike to the heart of the (...) contemporary debate on scientific realism. But even with the support of some revisions and a new thirty-page postscript, for a mainstream philosopher of science, the book falls short of seriously advancing the current debates, feeling quite dated overall and lacking purposeful engagement with the past 25 years of research.There is more novelty on offer for those looking for an alternative, “continental” fix on the philosophy of science. An original element of Radder’s study is its appropriation of some of J .. (shrink)

With the careful use of the polywater episode in the history of chemistry as a case study, I will show that the distinction recently made in the philosophy of science between experimenting on an entity and manipulating that entity is best seen as a distinction between experimenting on, and experimenting with, that entity. The polywater case also reveals that Ian Hacking's 1983 manipulability criterion is not a necessary condition for realism, and that scientists can, and do, justifiably change their (...) minds as to the reality of theoretical entities.

While Ludwik Fleck's Genesis and Development of a Scientific Fact is mainly concerned with social elements in science, a central argument depends on his case study of the development of a serum test for syphilis, the Wasserman Reaction, which Fleck argues was the product of skill and of laboratory practice, not a simple discovery. Ian Hacking interprets the creation of new phenomena in science very differently, arguing that it can seen as an argument for scientific realism. Hacking's argument shows (...) that Fleck's case study does not lead to the conclusion Fleck expects, and may solve one of the main problems in Fleck's work, how to define an objective element of knowledge.

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

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)

The issue of scientific realism is discussed in terms of the specific details of the practice of experimental meson and baryon spectroscopy in the field of High-Energy Physics (HEP), during the period from 1966 to 1970. The philosophical positions of I. Hacking, A. Fine, J. Leplin, and N. Rescher that concern scientific realism are presented in such a manner as to allow for the evaluation of their appropriateness in the description of this experimental research field. This (...) philosophical analysis focuses on the empirical adequacy of these four philosophical models that purport to describe the process of acquiring knowledge of the physical world.

This paper defends a Hackingian approach to the scientific realism debate by arguing against mainstream realists’ and antirealists’ common claim that no experimental arguments for the reality of posited entities can be theory-independent. Opposing this claim, I argue that some experimental arguments can warrant belief in the existence of entities without depending on the truth of the theories that posit the entities and describe their properties and the theories that explain the interactions between the entities and the (...) experimental devices. To achieve this goal, I investigate Hacking’s case of electron spraying, the famous experiment of positioning atoms by means of a scanning tunnelling microscope, and some novel experiments that use Ashkin’s optical tweezers. By introducing the distinction between theoretical properties and ontic properties, I argue that we can build up some theory-independent criteria of reality on the basis of ontic properties. Manipulability is an ontic property and the manipulation criterion is thus a theory-independent one, which should be reexamined and used for those experimental cases along a local approach to the realism debate. Resisting the mainstream realists’ and antirealists’ objections, I contend that some experiments using optical tweezers can warrant belief in the existence of the experimented entities without depending on theories.

Edgar Zilsel offers a Marxist account of the rise of experimental science avoiding both crude determinism and the anti-scientific bias of much “Western Marxism.” This account supplements Don Ihde’s instrumental realism with a social account of the systematic extension of perception by instrumentation. The social contact of non-literate craftspeople with purely intellectual scholars forged the social basis of what became technoscience.

Experimental moral philosophy began to emerge as a methodology inthe last decade of the twentieth century, a branch of the largerexperimental philosophy approach. From the beginning,it has been embroiled in controversy on a number of fronts. Somedoubt that it is philosophy at all. Others acknowledge that it isphilosophy but think that it has produced modest results at best andconfusion at worst. Still others think it represents an important advance., Before the research program can be evaluated, we should have someconception (...) of its scope. But controversy surrounds questionsabout its boundaries as well. Uncontroversially, the distinctionbetween experimental and non-experimental philosophy is not identicalto the distinction between a posteriori and a prioriphilosophy. Experimental evidence is a proper subset of empiricalevidence, which is itself a subset of a posteriorievidence.

We report the results of a study that investigated the views of researchers working in seven scientific disciplines and in history and philosophy of science in regard to four hypothesized dimensions of scientific realism. Among other things, we found that natural scientists tended to express more strongly realist views than social scientists, that history and philosophy of science scholars tended to express more antirealist views than natural scientists, that van Fraassen’s characterization of scientific realism failed to cluster with (...) more standard characterizations, and that those who endorsed the pessimistic induction were no more or less likely to endorse antirealism.

Experimental philosophy of aesthetics has explored to what extent ordinary people are committed to aesthetic realism. Extant work has focused on attitudes to normativism – a key commitment of realist positions in aesthetics – the claim that aesthetic judgments/statements have correctness conditions, invariant between subjects, such that there is a fact of the matter in cases of aesthetic disagreement. The emerging picture is that ordinary people strongly and almost universally reject normativism and thus there is no strong realist (...) tendency in ordinary people’s thinking about the aesthetic. This has been taken to dissolve the traditional puzzle in aesthetics of how to best account for the fact that (a) aesthetic judgments seem intersubjectively valid, while (b) aesthetic experience seems subjective. This paper presents studies which further enrich our understanding of ordinary thinking about the aesthetic: ordinary thinking about the aesthetic may not be so vehement in its rejection of normativism; and where previous results suggested that, in many cultures, the dominant trend is to reject correctness conditions for aesthetic judgments, the current results suggest participants think aesthetic judgments have correctness conditions (albeit perhaps very finely relativized to specific circumstances of judgment).

Scientific realism does not view theoretical terms as mere instruments of experimental predictions; it grants referential status to natural kind terms with 'epistemic access' and view scientific theories and terms as corresponding to physical phenomena and entities which exist independently of observation, and as thereby being the source of objective -approximate and not absolute- knowledge of the physical realm. As a result, scientific realism is accused of ontologising the unobservables. Against this charge, scientific realism posits the (...) idea of the dialectical relation between theoretical terms referring to the unobservables and scientific methods. The second argument made by realism is the ‘no miracle’ thesis. These arguments stand challenged by the Copenhagen interpretation of quantum mechanics. The aim of the paper is to examine the relevance of the two arguments of scientific realism in countering the idea that the existence of quantum states in the microphysical world renders realism obsolete.

In the past decade, experimental philosophy---the attempt at making progress on philosophical problems using empirical methods---has thrived in a wide range of domains. However, only in recent years has aesthetics succeeded in drawing the attention of experimental philosophers. The present paper constitutes the first survey of these works and of the nascent field of 'experimental philosophy of aesthetics'. We present both recent experimental works by philosophers on topics such as the ontology of aesthetics, aesthetic epistemology, aesthetic (...) concepts, and imagination, as well as research from other disciplines that not only are relevant to philosophy of aesthetics but also open new avenues of research for experimental philosophy of aesthetics. Overall, we conclude that the birth of an experimental philosophy of aesthetics is good news not only for aesthetics but also for experimental philosophy itself, as it contributes to broaden the scope of experimental philosophy.

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.

Recent work in philosophy of science has shown how the challenges posed by extremely complex systems require that scientists employ a range of modelling strategies, leading to partial perspectives that make apparently conflicting claims about the target (Mitchell 2009b, Longino 2013). The brain is of course extremely complex, and the same arguments apply here. In this paper I present a variety of perspectivism called _haptic realism_. This account foregrounds the process by which the instrumental goals of neuroscience shape the way (...) that objects of investigation are probed experimentally and conceptualised through modelling. Because such models do not aim to represent their targets exactly as they are, but in ways that are most useful for the investigators, the models should not be interpreted as literal descriptions of neural systems. Scientific realism traditionally involves a semantic commitment to interpreting theories and models as literal descriptions of human-independent nature. Haptic realism makes a significant departure from this tradition. Haptic realism also calls us to reassess the ontological commitments and knowledge claims of neuroscientific models and theories.

Relying on the notion of “overlapping perspectives,” this paper argues that entity realism and perspectivism are complementary. According to entity realism, it is justified to maintain a positive attitude toward the existence of unobservable entities with which multiple experimental interactions are possible. Perspectivism also explains that our beliefs about these entities are bounded by historically contingent theoretical and instrumental perspectives. The argument of the paper is developed through a discussion of Ronald Giere’s versions of realism: entity (...) realism, constructive realism, and perspectival realism. (shrink)

Many philosophers argue that the face-value of moral practice provides presumptive support to moral realism. This paper analyses such arguments into three steps. (1) Moral practice has a certain face-value, (2) only realism can vindicate this face value, and (3) the face-value needs vindicating. Two potential problems with such arguments are discussed. The first is taking the relevant face-value to involve explicitly realist commitments; the second is underestimating the power of non-realist strategies to vindicate that face-value. Case studies (...) of each of these errors are presented, drawn from the writings of Shafer-Landau, Brink and McNaughton, and from recent work in experimental metaethics. The paper then considers weak presumptive arguments, according to which both realist and non-realist vindications of moral practice are possible, but the realist vindications are more natural. It is argued that there is no sense of ‘natural’ available that can make these arguments work. The conclusion is that all extant presumptive arguments for moral realism fail. (shrink)

This paper aims to defend the use of the notion of experimental individuation, which has recently been developed by Ruey-Lin Chen, as a criterion for the reality of theoretical entities. In short, when scientists experimentally individuate an entity, a realist conclusion about that entity is warranted. We embed this claim regarding experimental individuation within a framework that allows for other criteria of reality. And we understand so-called retail arguments regarding the reality of a particular theoretical entity as arguments (...) that concern choosing an appropriate criterion of reality for that entity and determining whether the relevant first-order scientific evidence satisfies that criterion. We argue that such retail arguments are philosophical because defending criteria of reality, and showing that they are or are not satisfied in particular cases, involves work that is distinctively philosophical. And we illustrate this philosophical work by applying our criterion of experimental individuation to three historical cases: Davy’s potassium, Lavoisier’s muriatic radical, and Thomson’s electrified particles.

In this paper, inspired by the late twentieth century developments in philosophy of science, I propose an ontological scheme to accommodate the scientifically-informed anti-substantivalist views of the self. I call the position structural realist theory of the self. More specifically, I argue that SRS provides a middle ground for bringing a metaphysical reconciliation between the two recurring, and apparently competing forms of such anti-substantivalist views, i.e., eliminativism and pluralism. The notion of the structural self, as the underpinning pattern that is (...) the subject of the ontological commitments in SRS, is not as cumbersome as the orthodox substantivalist notion, and yet accounts for the relation of the different aspects and elements of the self by integrating them structurally into a central unifying pattern of selfhood. I use the experimental studies of Northoff et al. about the processing of the self-related stimuli in the cortical midline structure of the brain, to argue that the underlying pattern of the selfhood could be sought at the level of information processing. I also add a programmatic suggestion about how the different situated, experiential and extended aspects of the selfhood could be structurally incorporated into this underlying pattern. (shrink)

People disagree about whether “moral facts” are objective facts like mathematical truths (moral realism) or simply products of the human mind (moral antirealism). What is the impact of different meta-ethical views on actual behavior? In Experiment 1, a street canvasser, soliciting donations for a charitable organization dedicated to helping impoverished children, primed passersby with realism or antirealism. Participants primed with realism were twice as likely to be donors, compared to control participants and participants primed with antirealism. In (...) Experiment 2, online participants primed with realism as opposed to antirealism reported being willing to donate more money to a charity of their choice. Considering the existence of non-negotiable moral facts may have raised the stakes and motivated participants to behave better. These results therefore reveal the impact of meta-ethics on everyday decision-making: priming a belief in moral realism improved moral behavior. (shrink)

Science should tell us what the world is like. However, realist interpretations of physics face many problems, chief among them the pessimistic meta induction. This book seeks to develop a realist position based on process ontology that avoids the traditional problems of realism. Primarily, the core claim is that in order for a scientific model to be minimally empirically adequate, that model must describe real experimental processes and dynamics. Any additional inferences from processes to things, substances or objects (...) are not warranted, and so these inferences are shown to represent the locus of the problems of realism. The book then examines the history of physics to show that the progress of physical research is one of successive eliminations of thing interpretations of models in favor of more explanatory and experimentally verified process interpretations. This culminates in collections of models that cannot coherently allow for thing interpretations, but still successfully describe processes. (shrink)

Magnus and Callender argue that we ought to focus on retail arguments, which are arguments regarding the existence of particular kinds of theoretical entities, as opposed to theoretical entities in general. However, scientists are the ones who put forward retail arguments, and it’s unclear how philosophers can engage with such arguments. We argue that philosophers can engage with retail arguments by providing criteria that they must satisfy in order to demonstrate the existence of theoretical entities. We put forward experimental (...) individuation as such a criterion---when scientists experimentally individuate an entity, a realist conclusion about that entity is warranted. (shrink)

The paper is focused on some aspects of experimental realism of Ian Hacking, and especially on his manipulability criterion of existence. The problem is here related to chemical molecules, the objects of interest in chemical research. The authors consider whether and to what extent this criterion has been applied in experimental practice of chemistry. They argue that experimentation on is a fundamental criterion of existence of entities in chemistry rather than experimentation with. Some examples regarding studies of (...) structures of complex compounds, taken from organic chemistry, are presented to support the authors' considerations. Chemists' laboratory practice depends strongly on the way that representations of entities on (or with) the experiments are used. The authors show that this point has not been given sufficient attention by the new experimentalists. (shrink)

This article is a prelude to an experimental study of the preference concept in economics. I argue that a new empirical approach called experimental philosophy of science is a promising approach to advance the philosophy of economics. In particular, I discuss two debates in the field, the neuroeconomics controversy and the commonsensible realism debate, and suggest how experimental and survey techniques can generate data that will inform these debates. Some of the likely objections from philosophers and (...) economists are addressed, and possible ways of operationalizing different preference concepts are illustrated. (shrink)

Many metaethicists agree that as ordinary people experience morality as a realm of objective truths, we have a prima facie reason to believe that it actually is such a realm. Recently, worries have been raised about the validity of the extant psychological research on this argument’s empirical hypothesis. Our aim is to advance this research, taking these worries into account. First, we propose a new experimental design for measuring folk intuitions about moral objectivity that may serve as an inspiration (...) for future studies. Then we report and discuss the results of a survey that was based on this design. In our study, most of our participants denied the existence of objective truths about most or all moral issues. In particular, many of them had the intuition that whether moral sentences are true depends both on their own moral beliefs and on the dominant moral beliefs within their culture. This finding suggests that the realist presumptive argument may have to be rejected and that instead anti-realism may have a presumption in its favor. (shrink)
