Ontological realism is a philosophical stance that provides a definitional framework for ontologies and is referred to by various applied ontologists. From a computer science perspective, ontologies are often associated with formal languages for the representation of ontologies like the Web Ontology Language (OWL). It has, however, not been made explicit how the realist framework is related to the representation formalism. We analyse how the representational units of OWL can be used for modelling realist ontologies. While OWL is sufficiently (...) close to the realist framework of ontologies to describe them, there are categories in OWL that are alien to realist ontologies or duplicate categories in realist ontologies. This clarification allows separating talk about ontologies in general from talk about their specific representation. (shrink)

In this paper we explain how the intentional objects of our mental states can be represented by the intensional objects of conceptual realism. We first briefly examine and show how Brentano’s actualist theory of judgment and his notion of an immanent object have a clear and natural representation in our conceptualist logic of names. We then briefly critically examine Meinong’s theory of objects before turning finally to our own representation of intentional objects in terms of the intensional objects of (...) conceptual realism. We conclude by explaining why existence-entailing concepts are so basic to our commonsense framework and how these concepts and their intensions can be used to model Meinong’s ontology. (shrink)

Bertolt Brecht and Theodor W. Adorno stand for opposing modes and stances within an artistic modernism oriented toward radical social transformation. In his 1962 essay ‘Commitment’, Adorno advanced a biting critique of Brecht’s work and artistic position. Adorno’s arguments have often been dismissed but, surprisingly, are seldom closely engaged with. This paper assesses these two approaches that have been so central to twentieth-century debates in aesthetics: Brecht’s dialectical realism and Adorno’s sublime or dissonant modernism. It provides what still has (...) been missing: a close reading and immanent critique of Adorno’s case against Brecht. And it clarifies one methodological blind spot of Adorno’s formalist conceptualisation of autonomy: he fails to provide the detailed analysis of context that his own dialectical method immanently calls for. The paper shows how and why Brecht’s dialectical realism holds up under Adorno’s attack, and draws conclusions for contemporary artistic practice. (shrink)

We disagree with Almaatouq et al. that no realistic alternative exists to the “one-at-a-time” paradigm. Seventy years ago, Egon Brunswik introduced representative design, which offers a clear path to commensurability and generality. Almaatouq et al.'s integrative design cannot guarantee the external validity and generalizability of results which is sorely needed, while representative design tackles the problem head on.

We examine two very different approaches to formalising real computation, commonly referred to as “Computable Analysis” and “the BSS approach”. The main models of computation underlying these approaches—bit computation and BSS, respectively—have also been put forward as appropriate foundations for scientific computing. The two frameworks offer useful computability and complexity results about problems whose underlying domain is an uncountable space. Since typically the problems dealt with in physical sciences, applied mathematics, economics, and engineering are also defined in uncountable domains, it (...) is fitting that we choose between these two approaches a foundational framework for scientific computing. However, the models are incompatible as to their results. What is more, the BSS model is highly idealised and unrealistic; yet, it is the de facto implicit model in various areas of computational mathematics, with virtually no problems for the everyday practice. This paper serves three purposes. First, we attempt to delineate what the goal of developing foundations for scientific computing exactly is. We distinguish between two very different interpretations of that goal, and on the separate basis of each one, we put forward answers about the appropriateness of each framework. Second, we provide an account of the fruitfulness and wide use of BSS, despite its unrealistic assumptions. Third, according to one of our proposed interpretations of the scope of foundations, the target domain of both models is a certain mathematical structure. In a clear sense, then, we are using idealised models to study a purely mathematical structure. The third purpose is to point out and explain this intriguing phenomenon and attempt to make connections with the typical case of idealised models of empirical domains. (shrink)

A century after the discovery of quantum mechanics, the meaning of quantum mechanics still remains elusive. This is largely due to the puzzling nature of the wave function, the central object in quantum mechanics. If we are realists about quantum mechanics, how should we understand the wave function? What does it represent? What is its physical meaning? Answering these questions would improve our understanding of what it means to be a realist about quantum mechanics. In this survey article, I review (...) and compare several realist interpretations of the wave function. They fall into three categories: ontological interpretations, nomological interpretations, and the sui generis interpretation. For simplicity, I will focus on non-relativistic quantum mechanics.

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 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.

Moral realism and antirealist-expressivism are of course incompatible positions. They disagree fundamentally about the nature of moral states of mind, the existence of moral states of affairs and properties, and the nature and role of moral discourse. The central realist view is that a person who has or expresses a moral thought is thereby in, or thereby expresses, a cognitive state of mind; she has or expresses a belief that represents a moral state of affairs in a way that (...) might be accurate or inaccurate. The view of antirealist-expressivism is that such a person is in, or expresses, a conative state of mind, one that consists in a certain kind of attitude or motivational stance toward something, such as an action or a person. Realism holds that moral thoughts have truth conditions and that in some cases these truth conditions are satisfied so that our moral thoughts are true. Antirealist-expressivism holds, to a first approximation, that the distinctive moral content of a moral thought does not have truth conditions. (shrink)

In this paper I wish to connect the recent debate in the philosophy of quantum mechanics concerning the nature of the wave function to the historical debate in the philosophy of science regarding the tenability of scientific realism. Being realist about quantum mechanics is particularly challenging when focusing on the wave function. According to the wave function ontology approach, the wave function is a concrete physical entity. In contrast, according to an alternative viewpoint, namely the primitive ontology approach, the (...) wave function does not represent physical entities. In this paper, I argue that the primitive ontology approach can naturally be interpreted as an instance of the so-called ‘explanationism’ realism, which has been proposed as a response to the pessimistic-meta induction argument against scientific realism. If my arguments are sound, then one could conclude that: (1) contrarily to what is commonly though, if explanationism realism is a good response to the pessimistic-meta induction argument, it can be straightforwardly extended also to the quantum domain; (2) the primitive ontology approach is in better shape than the wave function ontology approach in resisting the pessimistic-meta induction argument against scientific realism.

This 1983 book is a lively and clearly written introduction to the philosophy of natural science, organized around the central theme of scientific realism. It has two parts. 'Representing' deals with the different philosophical accounts of scientific objectivity and the reality of scientific entities. The views of Kuhn, Feyerabend, Lakatos, Putnam, van Fraassen, and others, are all considered. 'Intervening' presents the first sustained treatment of experimental science for many years and uses it to give a new direction to debates (...) about realism. Hacking illustrates how experimentation often has a life independent of theory. He argues that although the philosophical problems of scientific realism can not be resolved when put in terms of theory alone, a sound philosophy of experiment provides compelling grounds for a realistic attitude. A great many scientific examples are described in both parts of the book, which also includes lucid expositions of recent high energy physics and a remarkable chapter on the microscope in cell biology.

For Descartes, knowledge exists as ideas in the mind that represent the world. In a radical critique, Hubert Dreyfus and Charles Taylor argue that knowledge consists of much more than the representations we formulate in our minds. They affirm our direct contact with reality—both the physical and the social world—and our shared understanding of it.

What is the nature of, and what is the relationship between, external objects and our visual perceptual experience of them? In this book, Frank Jackson defends the answers provided by the traditional Representative theory of perception. He argues, among other things that we are never immediately aware of external objects, that they are the causes of our perceptual experiences and that they have only the primary qualities. In the course of the argument, sense data and the distinction between mediate (...) and immediate perception receive detailed defences and the author criticises attempts to reduce perceiving the believing and to show that the Representative theory makes the external world unknowable. Jackson recognises that his views are unfashionable but argues in detail that they are to be preferred to their currently favoured competitors. It will become an obvious point of reference for all future work on the philosophy of perception. (shrink)

Realism and utopia usually represent antithetic political perspectives. In this essay I argue that these might find some common points by overtaking the secular interpretation they usually place on themselves.

Critical realism, a philosophical framework originally developed by Roy Bhaskar in the 1970s, represents a relatively new approach to research generally and to nursing research in particular. This article explores the ontological and epistemological tenets of critical realism and examines the application of critical realist principles to nursing research and practice through a review of the literature. It is evident that few published nursing research studies have, as of yet, utilized critical realism as their paradigm of choice. (...) Both the strengths and limitations of the presentation and use of critical realism in these studies are discussed in this article. Given the varying degrees of success of the authors in explicating critical realism as a philosophical framework, the value of critical realism to the research study, and the ways in which usage of the critical realist framework influenced development of the study and interpretation of findings, it is evident that the quality of future publications espousing the use of critical realism must continue to be strengthened significantly.

I examine the epistemological debate on scientific realism in the context of quantum physics, focusing on the empirical underdetermin- ation of different formulations and interpretations of QM. I will argue that much of the interpretational, metaphysical work on QM tran- scends the kinds of realist commitments that are well-motivated in the light of the history of science. I sketch a way of demarcating empirically well-confirmed aspects of QM from speculative quantum metaphysics in a way that coheres with anti-realist evidence (...) from the history of science. The minimal realist attitude sketched withholds realist com- mitment to what quantum state |Ψ⟩ represents. I argue that such commitment is not required for fulfilling the ultimate realist motiva- tion: accounting for the empirical success of quantum mechanics in a way that is in tune with a broader understanding of how theoretical science progresses and latches onto reality.

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.

Sherri Roush ([2005]) and I ([2001], [2006]) have each argued independently that the most significant challenge to scientific realism arises from our inability to consider the full range of serious alternatives to a given hypothesis we seek to test, but we diverge significantly concerning the range of cases in which this problem becomes acute. Here I argue against Roush's further suggestion that the atomic hypothesis represents a case in which scientific ingenuity has enabled us to overcome the problem, showing (...) how her general strategy is undermined by evidence I have already offered in support of what I have called the 'problem of unconceived alternatives'. I then go on to show why her strategy will not generally (if ever) allow us to formulate and test exhaustive spaces of hypotheses in cases of fundamental scientific theorizing. (shrink)

The end of the Cold War encourages new perspectives on international relations. Beer and Hariman provide a comprehensive set of essays that challenge and reinterpret the tradition of realism which has dominated the thinking of academics and foreign policy makers. Post-Realism: The Rhetorical Turn in International Relations systematically discusses the major realist writers of the Post-War era, the foundational concepts of international politics, and representative case studies of foreign policy discourse. These essays demonstrate how realism operates (...) rhetorically and point the way toward a richer understanding of world politics. (shrink)

It is commonly said of modern philosophy that it introduced a representative theory of perception, a theory that places representative mental items between perceivers and ordinary physical objects. Such a theory, it has been thought, would be a form of indirect realism: we perceive objects only by means of apprehending mental entities that represent them. The moral of the story is that what began with Descartes’s revolution of basing objective truth on subjective certainty ends with Hume’s paroxysms (...) of ambivalence and skepticism in the conclusion of the first book of the..

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)

The book's essays represent an important contribution to the contemporary philosophical debate concerning Realism and Rationalism. The author defends in a clear and consistent fashion a fallibilist, realistic, and rationalist position in opposition to the idealistic and relativistic viewpoint characteristic of present postmodern philosophy.

Mandelbaum adopted a middle course between physicalistic scientific realism and phenomenalistic "ordinary language" direct realism. He affirmed the relevance of scientific knowledge for epistemology, but did not attempt to reduce the content of perception to physical properties. Rather, he developed a critical direct realism, according to which we see bodies by means of having phenomenal experience. This phenomenal experience was not, however, to be equated with the sense-data of the usual representative realism. Rather, it was (...) a perception of material objects by means of their qualities. In this way, he agreed with the phenomenological position of the Gestalt psychologist Wolfgang Koehler, who rejected the view that sense-data by themselves could provide an epistemic basis for knowledge claims. Koehler's position, too, may be described as a critical realism. As would Mandelbaum, he sought to give proper due to the phenomenal while also affirming its basis in a physical world of objects and brain processes. In its insistence on the reality and scientific respectability of the phenomenal, the critical realism of Mandelbaum and Koehler is distinct from the contemporaneous physicalism of Place and Smart.

Realism is a term that can be understood only by contrasting it with an opposite term, such as idealism or representationalism. But representationalism has indeed to presuppose something that is represented,in order for the representation to be possible at all. This does not mean,however, to fall prey to a naïve realism: our grasp on reality is always determined by our own way of accessing it. A realism which can take hold of this presupposition is to be called (...) phenomenological realism. In this sense, reality is always given only in representation, that is, mediated by our access to it, but is not itself representation. It is an objectivity opposed to ourself, it has a particular place and it appears, but its appearance does not belong to the subject, it is simply there. Therefore, appearances are spatial and have to be described as such. (shrink)

In order to examine the fit between realism and science, one needs to address two issues: the unit of science question (realism about which parts of science?) and the contents of realism question (which realism about science?). Answering these questions is a matter of conceptual and empirical inquiry by way local case studies. Instead of the more ordinary abstract and global scientific realism, what we get is a doubly local scientific realism based on a (...) bottom-up strategy. Representative formulations of the former kind are in terms of the truth and reality of the posits of current science, in terms of warranted belief, in terms of mind-independent unobservable entities. Using illustrations mainly from the social sciences, doubly local scientific realism denies the global applicability of such formulations and seeks to make adjustments in their elements in response to information about local units of science: It is sufficient for a realist to give the existence of an entity (and the truth of a theory) a chance, while in some areas we may be in s position to make justified claims about actual existence (and truth). Logical inquiry-independent existence is sufficient for the social and human sciences, while mind-independence will be fine for many other domains. It should not be insisted that the theoretical posits of realist science be strict unobservables in all areas: most theoretical posits of the social sciences are idealized commonsensibles, such as elements in folk psychology. Unsurprisingly, this sort of local strategy will create space for realism that is able to accommodate larger areas of science without sacrificing traditional realist intuitions. (shrink)

I start by defining “racial realism” in the broadest accepted way in the metaphysics of race.

I discuss how metaphysicians of race have defended racial realism (...) according to how ordinary people use “race” in Part II. (shrink)

A new account of the semantic function (character) of ‘real’ and ‘really’ is defended. ‘Really’ as a sentential operator typically indicates that a report of what has been represented elsewhere ends and subsequent discourse is to be taken as making claims about the world. ‘Real’ and ‘really’ as applied to nouns or predicate phrases indicate that something is not being called an F merely because it represents an F. A way of drawing the distinction between realism and anti-realism (...) based on this new account is also defended. (shrink)

Preanalytically, we are all scientific realists. But both philosophers and scientists become uncomfortable when forced into analysis. In the case of scientists, this discomfort often arises from practical difficulties in setting out a carefully described set of objects which adequately account for the phenomena with which they are concerned. This paper offers a set of representative examples of these difficulties for contemporary physicists. These examples challenge the traditional realist vision of mature scientific activity as struggling toward an ontologically well-defined (...) world picture. They challenge antirealist alternatives as well. (shrink)

This article defends the normative relevance of the representation of non-citizens in democracies. I argue that representation within nation-states constitutes a realistic institutionalisation of the All-Affected Principle, allowing justificatory practices towards non-citizens and establishing political institutions that can realise the ideal of inclusion of all externally affected individuals. I defend electoral, non-electoral and surrogate forms of representation of affected interests that satisfy both the cosmopolitan concern for the equal consideration of interests and the statist defence of the importance of a (...) territorially and civically bounded demos. I assess piecemeal implementations of representation practices, namely reciprocal representation, ombudspersons, self-appointed representatives and deliberative and advocacy groups. Gradual and pluralised means of representation constitute necessary and feasible first steps to consider affected interests and offer an alternative route to an all-or-nothing defence of inclusion as national enfranchisement.

Advocates of scientic realism typically respond to the challenge of the pessimistic meta-induction by turning to the history of science. The episode most frequently discussed is the shift from Fresnel's wave theory of light to Maxwell's electromagnetism. This particular history is taken to represent one of the hardest problems for the realist, for while it exhibits continuity on the empirical level, it simultaneously represents a dramatic shift in ontology. Thus, various authors have proposed methods for defeating the pessimistic meta-induction (...) based solely on consideration of the Fresnel-Maxwell case. In this paper, I present another case study from physics--Fermi's 1934 theory of beta-decay and the ensuing search for a universal description of weak interactions. I argue that the degree of success of two recent proposals for scientic realism--that of John Worrall (1989, 1994, 2007) and Juha Saatsi (2005)--changes importantly in light of this new case study.

Ethical realists hold that our ethical concepts, thoughts, and claims are in the business of representing ethical reality, by representing evaluative or normative properties and facts as aspects of reality, and that such representations are at least sometimes accurate. Non-naturalist realists add the further claim that ethical properties and facts are ultimately non-natural, though they are nonetheless worldly. My aim is threefold: to elucidate the sort of representation involved in ethical evaluation on realist views; to clarify what exactly is represented (...) and how non-naturalism comes into the picture for non-naturalists; and to defend worldly non-naturalism against some objections. The first question addressed is how we should model evaluation on any realist view, which should in turn guide the identification of which properties and facts are credibly regarded as ‘evaluative’ ones. Then the question is: what role might non-natural properties and facts play, and how are they related to what is represented in ethical evaluation? Once that is clear, we will be in a position to answer certain objections to non-naturalist realism from Jackson, Gibbard, Bedke, and Dreier. I argue that the objections all mischaracterize the role played by non-natural properties and facts on plausible versions of non-naturalist realism. (shrink)

Bruineberg and colleagues' critique of Friston blankets relies on what we call the “literalist fallacy”: the assumption that in order for Friston blankets to represent real boundaries, biological systems must literally possess or instantiate Markov blankets. We argue that it is important to distinguish a realist view of Friston blankets from the literalist view of Bruineberg and colleagues’ critique.

This article is Part II in a pair of articles on racial realism. In Part I, I defined “racial realism” and discussed the major attempts in the past twenty years among metaphysicians of race and biologists to defend racial realism from the viewpoint of what biologists mean by “race.” In this article, I continue discussing and critiquing how metaphysicians of race have conceived of and defended racial realism, but with a focus on how ordinary people use (...) “race.” I focus on two broad groups of racial realisms in this article: biological racial realism and social racial realism. After defining each one, I summarize a representative sample of recent attempts from metaphysicians of race to defend both types of racial realism. I also discuss major criticisms against each attempt. I end by sketching a new, radical pluralist way of being a racial realist, and I provide some empirical motivation for why it's promising.

A natural way to think of models is as abstract entities. If theories employ models to represent the world, theories traffic in abstract entities much more widely than is often assumed. This kind of thought seems to create a problem for a scientific realist approach to theories. Scientific realists claim theories should be understood literally. Do they then imply the reality of abstract entities? Or are theories simply—and incurably—false? Or has the very idea of literal understanding to be abandoned? Is (...) then fictionalism towards scientific theories inevitable? This paper argues that scientific realism can happily co-exist with models qua abstracta. (shrink)

Southern Africa, where most of these book chapters originate, has been identified as one of regions of the world most at risk of the consequences of environmental degradation and climate change. At the same time, it is still seeking ways to overcome the century long ravages of colonial and apartheid impositions of structural and epistemic violence. Research deliberations and applied research case studies in environmental education and activism from this region provide an emerging contextualized engagement that is related to a (...) wider internationally articulated quest to achieve social-ecological justice, resilience and sustainability through educational interventions. This book introduces a decade of mainly southern African critical realist environmental education research and thinking that asks the question: "How can we facilitate learning processes that will lead to the flourishing of the Earth’s people and ecosystems in more socially just ways?" The environmental education research topics represented in this book are wide-ranging. However, they all exhibit the common theme of social justice and wanting to create change towards a better future. All the authors have used critical realist or critical realist-influenced research methodologies. Offering contributions from a small but growing community of researchers working with critical realism in the global South, this book will be of interest to students, scholars and practitioners in the areas of environmental education, sustainability, development and the philosophy of critical realism in general.

This paper shows how critical realism can be used to integrate empirical data and philosophical analysis within ‘empirical bioethics’. The term empirical bioethics, whilst appearing oxymoronic, simply refers to an interdisciplinary approach to the resolution of practical ethical issues within the biological and life sciences, integrating social scientific, empirical data with philosophical analysis. It seeks to achieve a balanced form of ethical deliberation that is both logically rigorous and sensitive to context, to generate normative conclusions that are practically applicable (...) to the problem, challenge, or dilemma. Since it incorporates both philosophical and social scientific components, empirical bioethics is a field that is consistent with the use of critical realism as a research methodology. The integration of philosophical and social scientific approaches to ethics has been beset with difficulties, not least because of the irreducibly normative, rather than descriptive, nature of ethical analysis and the contested relation between fact and value. However, given that facts about states of affairs inform potential courses of action and their consequences, there is a need to overcome these difficulties and successfully integrate data with theory. Previous approaches have been formulated to overcome obstacles in combining philosophical and social scientific perspectives in bioethical analysis; however each has shortcomings. As a mature interdisciplinary approach critical realism is well suited to empirical bioethics, although it has hitherto not been widely used. Here I show how it can be applied to this kind of research and explain how it represents an improvement on previous approaches. (shrink)

According to an influential view, when it comes to representing reality, some words are better suited for the job than others. This is elitism. There is reason to believe that the set of the best, or elite, words should not be redundant or arbitrary. However, we are often forced to choose between these two theoretical vices, especially in cases involving theories that seem to be mere notational variants. This is the riddle of redundancy: both redundancy and arbitrariness are vicious, but (...) there are cases in which one must be picked. Logical realists admit that there are some logical constants among the elite words. This leads to awkward questions, such as which among conjunction and disjunction is elite. In this paper, I show how the riddle of redundancy arises for logical realists, and offer a solution. This approach requires us to change how we represent negation. Instead of using some particular symbol, we represent negation by flipping formulae over the horizontal axis. (shrink)

Hindu jurisprudential texts contain elaborate and careful philosophical reflections on the nature of law and religion.

Realism about quantum theory naturally leads to realism about the quantum state of the universe. It leaves open whether it is a pure state represented by a wave function, or an impure one represented by a density matrix. I characterize and elaborate on Density Matrix Realism, the thesis that the universal quantum state is objective but can be impure. To clarify the thesis, I compare it with Wave Function Realism, explain the conditions under which they are (...) empirically equivalent, consider two generalizations of Density Matrix Realism, and answer some frequently asked questions. I end by highlighting an implication for scientific realism. (shrink)

Realistic uses of Virtual Reality technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception may be extended to cover such cases. Virtual objects are explained as concrete models that have an inner generation mechanism, and the ITP is used to explain how VR users can both perceive such local CMs, and perceptually represent remote real objects. Also, concepts of modeling and representation are distinguished. The paper (...) concludes with suggestions as to how the ITP methodology developed here could be extended to iconic external representations and models generally. (shrink)

"The first two lectures place the alternative I defend -- a kind of pragmatic realism -- in a historical and metaphysical context. Part of that context is provided by Husserl's remark that the history of modern philosophy begins with Galileo -- that is, modern philosophy has been hypnotized by the idea that scientific facts are all the facts there are. Another part is provided by the analysis of a very simple example of what I call 'contextual relativity'. The position (...) I defend holds that truth depends on conceptual scheme and it is nonetheless 'real truth'. "In my third lecture I turn to the Kantian antecedents of this view, explaining what I think should be retained of the Kantian idea of autonomy as the central theme of morality, and extracting from Kant's work a 'moral image of the world' that connects the ideals of equality and intellectual liberty. In this lecture I defend the idea that moral images are an indispensible part of our moral and cultural heritage. "In the final lecture I defend the idea of moral objectivity. I compare our epistemological positions in ethics, history, analysis of human character, and science, and I argue that in no area can we hope for a 'foundation' which is more ultimate than the beliefs that actually, at a given time, function as foundational in the area, the beliefs concerning which one has to say 'this is where my spade is turned'. In ethics such beliefs are represented in moral images of the world.". (shrink)

Ruben Berrios Queen’s University Belfast Anti-realism and Aesthetic Cognition Abstract At the core of the debate between scientific realism and anti-realism is the question of the relation between scientific theory and the world. The realist possesses a mimetic conception of the relation between theory and reality. For the realist, scientific theories represent reality. The anti-realist, in contrast, seeks to understand the relations between theory and world in non-mimetic terms. We will examine Cartwright’s simulacrum account of explanation in (...) order to illuminate the anti-realist position. Science consists of phenomenological and theoretical laws. The former are concerned with appearances, or those phenomena that can be directly observed; the latter involve the unobservable reality that is alleged to underlie appearances, and are capable only of indirect confirmation. Phenomenological laws are said to be descriptive, whilst theoretical laws are understood as explanatory. Cartwright is concerned with the theoretical. She claims that the standard realist account of the explanatory efficacy of theoretical laws is faulty. The explanatory power of theoretical laws consists in their ability to provide an explanation of physical phenomena. According to Cartwright, the realist claims that laws explain phenomena by providing an abstract description of them, in terms of their micro-structural features, that is alleged to be true. On this view, explanatory power is entirely dependent on descriptive adequacy. As phenomenological laws describe appearances, so theoretical laws describe the fundamental reality that governs appearances. Cartwright rejects the preceding view and in its place proposes a simulacrum account of explanation. According to Cartwright, the explanatory power of theoretical laws is related not to descriptive adequacy, but rather to the construction of adequate models. To explain a phenomenon is to construct a model which best or most adequately accommodates the phenomenon to a theory. The model will consist of various posited objects that serve to explain the phenomena in terms that are consistent with a set of theoretical laws. Cartwright claims that theoretical laws are true of, or describe, the objects of the model. The objects of the model, however, are not descriptive of reality. They are simulacra. They have, that is, the form or appearance of things, without possessing their substance or proper qualities. In light of the foregoing account we can summarise the distinction between scientific realism and anti-realism as follows. The realist claims that theoretical laws literally represent real objects. The anti-realist claims that laws represent objects of a model that are simulacra of reality. Anti-realism has an aesthetic dimension. The movement from realism to anti-realism is also the movement from the mimetic conception of the scientist as holding a mirror to nature to the constructionist view of the scientist as engaging with nature through invention. There is a lot of the artist in the anti-realist’s view of the scientist. This is true for Cartwright as well as, for example, Van Fraassen in his doctrine of constructive empiricism. It would appear, then, that the philosophy of science has absorbed some concepts that are ordinarily housed in aesthetics. And it has done so profitably. The aim of this paper is to reverse the direction of disciplinary influence. Can art, in relation to its status as a cognitive enterprise, be illuminated by scientific anti-realism? I will argue that it can. In an unexpected reference to the Nicomachean Ethics, Cartwright draws a suggestive parallel between theoretical laws and general moral principles, on the one hand, and physical phenomena and everyday moral conduct, on the other hand. If we add to this the claim that a central component of art’s value is cognitive, then we have the basic materials with which to flesh out a broadly anti-realist view of art. In the production of art, artists can construct models that mediate between everyday ethical phenomena and general ethical tendencies. These models reveal the ways in which there are implicit consistencies or inconsistencies, conflicts or congruences and so forth, between the phenomena and the tendencies. On this basis art can contribute to the reflective understanding of ethical life. This constitutes to a large degree art’s status as a cognitive enterprise. To apprehend art cognitively as artist or critic is to engage in aesthetic cognition. (shrink)

The decision whether to have a realist or an anti-realist attitude towards scientific hypotheses is interpreted in this paper as a choice that scientists themselves have to face in their work as scientists, rather than as a ‘philosophical’ problem. Scientists’ choices between realism and instrumentalism are interpreted in this paper with the help of two different conceptual tools: a deflationary semantics grounded in the inferentialist approach to linguistic practices developed by some authors, and an epistemic utility function that tries (...) to represent the cognitive preferences of scientists. The first tool is applied to two different questions traditionally related to the problem of scientific realism: the non-miracle argument, and the continuity of reference. The second one is applied to the problem of unconceived alternatives, and to the distinction between realist and instrumentalist attitudes towards scientific hypotheses. (shrink)
