This paper distinguishes three concepts of "race": bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards' 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially crucial to the first episode, while normativity is central to the second. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. We conclude by (...) interrogating the relevance of these scientific discussions for political positions and a post-racial future. (shrink)

La critica all’antirealismo costruttivista del pensiero postmoderno è al centro della riflessione di Maurizio Ferraris per lo meno a partire da Il mondo esterno (Ferraris 2001). Forme radicali di costruttivismo sono state però difese anche al di fuori del pensiero postmoderno tanto nella tradizione della filosofia analitica quanto, più recentemente, nell’ambito delle scienze cognitive. Nell’articolo viene dapprima presentata e criticata un’affermazione dal netto sapore costruttivista fatta da Vittorio Gallese e George Lakoff in uno degli articoli più influenti nel dibattito degli (...) ultimi anni sulla natura dei concetti: The Brain’s Concepts (Gallese, Lakoff 2005). Tale posizione viene quindi messa in relazione con quella forma di antirealismo costruttivista, detta anche relativismo concettuale, difesa, in modi e con esiti diversi, da filosofi quali Nelson Goodman, Hilary Putnam e Richard Rorty. Si sostiene quindi che tutte queste forme di antirealismo costruttivista incorrono in un dilemma: o esse abbracciano la problematica tesi metafisica di un’efficacia causale a ritroso delle nostre menti sul mondo oppure si riducono a una plausibile, ma ontologicamente innocua, affermazione dell’esistenza, in linea di principio, di molteplici modi di categorizzare la realtà e, nel caso delle teorie cosiddette incarnate della cognizione, della dipendenza di tali modi dalle forme che assume l’interazione senso-motoria di un organismo col suo ambiente. Viene infine mostrato come dall’osservazione dei molteplici modi in cui è possibile categorizzare la realtà sia possibile trarre conclusioni metafisiche di segno opposto all’antirealismo costruttivista.

This book contains twelve chapters by leading and up-and-coming philosophers on metaepistemology, that is, on the nature, existence and authority of epistemic facts. One of the central divides in metaepistemology is between epistemic realists and epistemic anti-realists. Epistemic realists think that epistemic facts exist independently of human judgements and practices, and that they have authority over our judgements and practices. Epistemic anti-realists think that, if epistemic facts exist at all, they are grounded in human judgements and practices, and gain any (...) authority they have from our judgements and practices. This book considers both epistemic realist and anti-realist perspectives, as well as perspectives that 'transcend' the realism/anti-realism dichotomy. As such, it constitutes the 'state of the art' with regard to metaepistemology, and will shape the debate in years to come. (shrink)

In this essay I consider the relationship between Heidegger’s famous “turn” and realism. I begin with Heidegger’s critique of the problem of an external world, and I describe how this critique anticipates New Realism. I then provide a reconstruction of Heidegger’s self-critique of Being and Time, showing how this work exhibits a higher-order antirealism. Next, I show how Heidegger’s turn is motivated by the inadequacy of this earlier anti-realism. In his philosophy of the event he moves towards a realist (...) ontology by developing concepts such as “destiny”, which he understands to be independent of human attitudes. Nevertheless, Heidegger ultimately falls back into an anti-realism, because Being still remains dependent upon the involvement of human beings. I therefore conclude this essay by briefly arguing for my own version of New Realism, according to which objects are meaningful in a way that is independent of our attitudes towards them. (shrink)

The current state of philosophy of science is characterized by stasis in the struggle between realism and antirealism. In recent years, a number of authors have come out with a program of scientific perspectivism that claims to sublate this great collision and gain the status of a new epistemological paradigm: “perspectivism, or, better, perspectival realism, is one of the newest attempts to find a middle ground between scientific realism and antirealism” [1. P. 2]. Important milestones of the perspective (...) movement were the works of Ronald Giere, Francois Recanati, Bas van Fraassen, Michela Massimi, and others. The thesis of the article is that perspectivism has not yet realized its claims to autonomy, although it has become an important new arena for discussions between realists and antirealists who try to appropriate perspectivist concepts and arguments. The “middle ground,” when thought out consistently and thoroughly, turns out to lie not “between,” but either in the territory of realism or in the territory of antirealism, depending on the presumptions of the author of a particular perspectivist conception. This is demonstrated by the analysis of the conceptions of Giere, Massimi, and Recanati. Giere’s perspectivism is based on the metaphor of color vision, and for him only some (secondary) qualities of real objects turn out to be perspectival, i.e., subject-dependent. Massimi’s perspectivism attempts, on the basis of a visual arts metaphor, to combine the phenomenon of the plurality of scientific theories (“perspectival disagreement” about what an object is) with the general realist attitude of science (agreement about that there is an object). Recanati’s perspectivism syncretizes realism about ordinary objects and relativism about other things. The first two versions of perspectivism rely on a perceptual metaphor: perspective is conditioned by the perceptual constitution of the observer, that is, it arises at the mental or cognitive level. Recanati’s version attempts to derive perspective from contextuality, that is, it is semantic. However, it does not show exactly how perceptual categories are superimposed on theories or how scientific concepts reveal their perspectival character. The isomorphism of perception and theoretical thinking, sensibility and understanding, remains undemonstrated. On the one hand, perspectivist efforts are motivated by an important concern to account for antirealist critique (lack of access to the “view from nowhere,” factual and semantic underdetermination, difficulties with the idea of approaching the truth, the historicity of knowledge, the activeness of the constructing subject, etc.) while preserving the scientific commitment to universality, validity, and truthfulness. On the other hand, the ontological question remains fundamental and unavoidable, and perspectivism (yet?) fails to circumvent it. As we see, all three versions of perspectivism considered in this article turn out to be varieties of realism: Giere and Massimi recognize this explicitly, while Recanati de facto assumes a quite respectable and conservative position of selective realism with respect to ordinary objects.

The hermeneutical ontology proposed in this book steers away from the rocks of realism and anti-realism.

Up until recently social scientists took it for granted that their task was to account for the social world as objectively as possible: they were realists in practice if not always in their methodological sermons. This situation started to change in the 1960s, when a number of antirealist philosophies made inroads into social studies. -/- This paper examines critically the following kinds of antirealism: subjectivism, conventionalism, fictionism, social constructivism, relativism, and hermeneutics. An attempt is made to show that these (...) philosophies are false and are causing serious damage to social studies. -/- Next the subjective interpretation of probability is analyzed as a case of subjectivism. An approach to the subjective perception of justice is sketched as an example of the objective study of subjective experience. -/- Finally, the three main varieties of realism — naive, critical, and scientific — are outlined. It is argued that the scientific attitude involves scientific realism, which is put in practice even by scholars who, like Weber and Simmel, called themselves antirealists. (shrink)

The article resituates critical realism within critical theory and proposes a tripartite articulation of British critical realism, German critical theory and French anti-utilitarianism. It suggests that the critique of positivism has to be enhanced with a critique of utilitarianism and makes the case that both critiques have to be grounded in a hermeneutic approach to social life. By taking the symbolic constitution of the world seriously, critical realist hermeneutics offers a via media between naturalism and anti-naturalism, explanation and interpretation, universalism (...) and relativism, materialism and idealism, realism and constructivism.

The metaphysical realist asserts, while the metaphysical antirealist denies, that there are individuals that exist independently of the existence and workings of any mind or minds. I begin by distinguishing the thesis of metaphysical realism from other theses that are also called ' realism '. Of particular interest in this discussion is the relation between metaphysical realism and views such as moral realism and scientific realism. ; Metaphysical realism is commonly thought to be the default position in the debate since (...) it is prima facie supported by our commonsense intuitions concerning the nature of reality. I develop several arguments to show that, when we examine our intuitions in detail, metaphysical realism is not the entirely commonsensical view that it at first appears. I argue that if metaphysical realism is true, it is difficult to see how semantic and epistemic access to the mind-independent world is possible and that, even if we do have such access, it will be difficult to rule out very bizarre ontologies. While none of these arguments constitute a decisive objection to metaphysical realism, they do suggest that the metaphysical realist should say something in defense of his view. ;I then examine Peter van Inwagen's attempted defense of metaphysical realism. This defense takes the form of a series of arguments designed to show that metaphysical antirealism is incoherent because incompatible with the existence of objective truth. I argue that his criticisms do not constitute an adequate defense of metaphysical realism because certain forms of antirealism, if otherwise philosophically viable, plausibly escape. ;This leads to a discussion of the extent to which an antirealist metaphysic can be considered a viable philosophical view. In this context, I examine the views of Hilary Putnam and Paul Grice. While the versions of metaphysical antirealism presented face serious difficulties of their own, I argue that it is a matter of philosophical judgment which view, metaphysical realism or metaphysical antirealism, has the more severe problems.

This article explores and attempts to resolve some issues that arise when at stake is the incommensurability between the concepts of reality developed by philosophical hermeneutics, on the one hand, and realist branches of analytical philosophy, on the other. The view of hermeneutic realism is suggested not as a remedy against this incommensurability, but as a vehicle for revising those aspects of both hermeneutics and ontological realism which impede the dialogue between them. It is a view that opposes epistemological foundationalism, (...) Cartesian dualism, essentialism about theoretical objects, and cognitive relativism. The role of reading/textualizing in science’s spaces of representation is specified. (shrink)

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

Robinson's defense of moral realism is stimulating, admirable, and convincing in many respects. He is particularly effective in mounting a multi-faceted attack on Mackie's famous "argument from queerness" and other views that deny that moral realities can be part of the furniture of the world. Certain other of his arguments about the ontological standing of moral entities, however, might be seen to open rather a wide gulf between them and ordinary experience. I suggest that hermeneutic philosophy, which I find more (...) consonant with Robinson's project than he does, might step in to heal the breach. 2012 APA, all rights reserved). (shrink)

In a recent article, Sam Page distinguishes four kinds of mind-dependence : ontological, causal, structural, and individuative. He argues that, despite the fact that the metaphysical realism/antirealism debate has been frequently characterized as a debate between those who accept and those who deny that the world is causally and/or structurally dependent on minds, many antirealists are primarily interested in defending the claim that the world is individuatively mind-dependent. In this article, I critically examine these differing senses of “ mind-dependence (...) ” highlighting ways in which they remain ambiguous and identifying various entailment relations between them. I argue that there is reason to believe that ontological dependence, structural dependence, and the only sort of individuative dependence that is relevant to the metaphysical debate are coextensive notions. As such, any argument that succeeds in establishing that it is incoherent to suppose that everything is ontologically and/or structurally dependent thereby establishes the incoherence of metaphysical antirealism.

Quine’s desert is generally contrasted with Meinong’s jungle, as a sober ontological alternative to the exuberant luxuriance that comes with the latter. Here I focus instead on the desert as a sober metaphysical alternative to the Aristotelian garden, with its tidily organized varieties of flora and fauna neatly governed by fundamental laws that reflect the essence of things and the way they can be, or the way they must be. In the desert there are no “natural joints”; all the boundaries (...) we find are lines we have drawn, artificial fencings that merely reflect of our own demarcations, our classifications, our desperate need to ward off the flux and meet an excusable but ungrounded demand for order and stability. The desert returns a picture of reality that is radically anti-realist. And yet the picture does not amount to a form of irrealism. The desert is out there and is what it is regardless of how we feel. And it is not completely structureless. It’s just that the structure it has is very thin and does not correspond to the sort of structure that so-called metaphysical realists—and scientific realists alike—tend to attribute to it. (shrink)

The first part of the paper is a metatheoretical consideration of such philosophy of nature which allows for using scientific results in philosophical analyses. An epistemological 'judgment' of those results becomes a preliminary task of this discipline: this involves taking a position in the controversy between realistic and antirealistic accounts of science. It is shown that a philosopher of nature has to be a realist, if his task to build true ontology of reality is to be achieved. At the same (...) time he cannot be a realist ˗ a possibility that science itself is capable of deciding what beings really exist (a typical realistic claim is that scientific notions refer to something external and truly describe its characteristics) has to be denied, if the philosophy of nature is seen as a discipline investigating the natural world, while being epistemologically different from the natural sciences. A possibility of weakening this opposition is explored in the second part of the paper, where the idea of so-called "postulated ontology" of scientific theories is brought to the consideration. This idea appears in the context of a well-known thesis of the underdetermination of scientific theories by empirical data. It is argued in the paper, that the conviction of the existence of some kind of relation between a given theory and ontological ideas can be derived from this thesis, regardless of its particular form. Therefore, certain solutions to classical philosophical questions can be obtained, in principle, by careful inspection of scientific achievements. However, if the thesis of underdetermination holds, such philosophical solutions are not imposed by science itself. In order to arrive at some kind of ontology based on science, it seems necessary to accept certain philosophical presuppositions in the first place. This and the fact that scientific theories change in time show that although such a kind of ontology is possible, and perhaps desirable, it can never be ultimate. (shrink)

This paper argues that some defenses of global antirealism that critique both epistemic foundationalism and ontological priority foundationalism (e.g., Westerhoff 2020) turn on a false dilemma that ignores non-representational approaches to consciousness and cognition. Arguments against the existence of an external world and against introspective certainty, typically draw on a range of empirical findings (mainly about the brain-based mechanisms that realize cognition) and that are said to lend support to irrealism. Theories that incorporate these findings, such as the interface (...) theory of perception and predictive processing, not only retain the notion of the veil of perception, but have continued to assign to it an important theoretical role. While the mathematical frameworks these theories employ do make them viable candidates, neither theory is moving in a direction that would suggest global anti-realism is the more plausible attitude. Rather, I argue that the new paradigm of 4E cognitive science (embodied, embedded, enactive, extended) bolsters epistemological and metaphysical realism. (shrink)

My aim in this paper is to re-examine Arthur Fine’s concept of the natural ontological attitude. Whereas earlier critical interpretations focus on the compatibility of NOA with scientific realism, I argue that Fine’s conception is to be recast in terms of an interpretative theory of scientific research. Specifically, I make the case that the hermeneutic reformulation of NOA is unavoidable when at stake are the issues of the structural, conceptual, and experimental articulation of scientific domain. The paper concludes by considering (...) the formation of local epistemological positions in the research process. (shrink)

IntroductionThe aim of this paper is to outline the program of a hermeneutic theory of the way in which reality becomes disclosed and meaningfully articulated in practices of scientific inquiry.Text and MethodsI describe the profile of hermeneutic realism by addressing the issue of how objectified factuality is produced within the facticity of inquiry. Hermeneutic realism is characterized as a position that discards foundational epistemology and cognitive essentialism. I argue that the meaningful articulation of domains disclosed in scientific inquiry is an (...) ontologically self-sufficient process. This claim is the kernel of interpretive internalism. At stake in my analysis is the interplay of interrelated scientific practices and the possibilities for doing research, granted that the practices’ interrelatedness is projected upon the horizon of possibilities. Three kinds of hermeneutic circularity in this interplay are distinguished. They refer accordingly to the selection of data, the construction of data-models, and the saving of phenomena whereby theoretical objects become contextually envisioned. The main emphasis is placed on the reading of theoretical objects in the articulation of scientific domains.ConclusionThus, the kind of philosophy of science pertinent to hermeneutic realism and interpretive internalism aims at revealing reality within the facticity of inquiry.

I argue that there is a distinction to be drawn between two kinds of mental realism, and I draw some lessons for the realism-antirealism debate. Although it is already at hand, the distinction has not yet been drawn clearly. The difference to be shown consists in what realism is about: it may be either about the interpretation of folk psychology, or the ontology of mental entities. I specify the commitment to the fact-stating character of the discourse as the central (...) component of realism about folk psychology, and from this I separate realism about mental entities as an ontological commitment towards them. I point out that the two views are mutually independent, which provides the possibility of considering folk psychology as not being in cognitive competition with scientific psychology. At the end I make a tentative suggestion as to how to interpret the former in order to avoid this conflict. (shrink)

In _Realistic Rationalism_, Jerrold J. Katz develops a new philosophical position integrating realism and rationalism. Realism here means that the objects of study in mathematics and other formal sciences are abstract; rationalism means that our knowledge of them is not empirical. Katz uses this position to meet the principal challenges to realism. In exposing the flaws in criticisms of the antirealists, he shows that realists can explain knowledge of abstract objects without supposing we have causal contact with them, that numbers (...) are determinate objects, and that the standard counterexamples to the abstract/concrete distinction have no force. Generalizing the account of knowledge used to meet the challenges to realism, he develops a rationalist and non-naturalist account of philosophical knowledge and argues that it is preferable to contemporary naturalist and empiricist accounts. The book illuminates a wide range of philosophical issues, including the nature of necessity, the distinction between the formal and natural sciences, empiricist holism, the structure of ontology, and philosophical skepticism. Philosophers will use this fresh treatment of realism and rationalism as a starting point for new directions in their own research. (shrink)

In this paper we will analyze Lawson’s criticism of Hayek for not having transcended positivism. We will distinguish two levels in the criticism: methodological and ontological. So far as methodological criticism is concerned, we consider that Lawson’s positivist interpretation of Hayek regarding the method in economics is not the only possible, and we will try to develop another one. With respect to ontological criticism, we will state that though it is possible to understand Hayek as an ontological positivist, since he (...) assumes an ontological individualism, this fact would not necessarily lead to positivism -question to which Lawson seems to bring Hayek closer after 1955- but a moderate ontological individualism could be assigned to Hayek founded on a realistic interpretation of Husserl’s phenomenology.

Analytic metaphysics displays a meta-metaphysical pattern: A shift toward a foundational conception of the aims and methods of metaphysical enquiry and away from a pragmatic understanding of foundational questions of metaphysics. Pragmatism looms large in Carnap’s and Quine’s metaphysics, across the differences between ontological pluralism and antirealism and extensionalist ontological realism. The two philosophers share the pairing of a deflationary take on ontology and a pragmatist rendering of foundational issues. In particular, Quine complements his quantification-based ontology, which denies ontological (...) pluralism, with a pragmatic understanding of cognitive and explanatory significance. This pattern is traceable in Lewis’s modal realism. A different line in analytic meta-metaphysics is characterized by easing of pragmatist commitments and redefining the object of enquiry, from what there is to what is fundamental. I give and discuss examples of this different theoretical line and illustrate their contribution to the ineludible task of a philosophical revision of pragmatism. (shrink)

The paper tries to demonstrate how a hermeneutic critique of scientism raises important issues not only about the dialogue between (post)analytical and Continental philosophers but also about a third way of philosophizing that gets rid of traditional dilemmas and stubborn dividing lines inherited from the “two cultures” paradigm. In outlining a conception of hermeneutic realism, the paper elaborates on a distinction between ontic and ontological forms of realism. An ontic form specifies a certain range of entities whose existence is reified (...) as something “given”, as presence-at-hand. An ontological form of realism is realism about the reality that is ready-to-hand within the “readable technologies” of interrelated practices. The paper argues that the ontological forms of realism provide opportunities for combating scientism philosophically, while advocating a cognitive autonomy of science based upon the interpretative openness of scientific research.

In everyday speech we seem to refer to such things as abstract objects, moral properties, or propositional attitudes that have been the target of metaphysical and/or epistemological objections. Many philosophers, while endorsing scepticism about some of these entities, have not wished to charge ordinary speakers with fundamental error, or recommend that the discourse be revised or eliminated. To this end a number of non-revisionary antirealist strategies have been employed, including expressivism, reductionism and hermeneutic fictionalism. But each of these theories faces (...) forceful objections. In particular, we argue, proponents of these strategies face a dilemma: either concedes that their theory is revisionary, or adopt an implausible account of speaker-meaning whereby the content of certain types of utterance is opaque to their speakers. In this paper we introduce a new type of antirealist strategy, which is thoroughly non-revisionary, and leaves speaker-meaning transparent to speakers. We draw on work on pragmatics in the philosophy of language to develop a theory we call ‘pragmatic antirealism’. The pragmatic antirealist holds that while the sentences of the discourses in question have metaphysically contentious truth conditions, ordinary utterances of them are pragmatically modified in context in such a way that speakers do not incur commitment to those truth conditions. After setting out the theory, we show how it might be developed for both mathematical and ethical discourse, before responding to some likely objections. (shrink)

Fictionalism in ontology is a mixed bag. Here I focus on three main variants—which I label after the names of Pascal, Berkeley, and Hume—and consider their relative strengths and weaknesses. The first variant is just a version of the epistemic Wager, applied across the board. The second variant builds instead on the fact that ordinary language is not ontologically transparent; we speak with the vulgar, but deep down we think with the learned. Finally, on the Humean variant it’s the structure (...) of the ontological inventory, not its content, that may turn out to involve fictional elements. That is, for the Humean the fiction lies, not in the reality of common-sense ontology, but in the laws—of unity, identity, causation, etc.—in terms of which we articulate our experience of that reality. In the end, this is the kind of fictionalism that I find most interesting, sensible, and tenable. And I argue that it is even compatible with the sort of “naive” realism we have all come to appreciate in the work of Paolo Bozzi, to whom the paper is dedicated. (shrink)

On a standard reading of David Hume, we know two things about his analogy of morals to secondary qualities: first, it responds to the moral rationalism of Clarke and Wollaston; second, it broadcasts Hume’s realism or antirealism in ethics. I complicate that common narrative with a new intellectual contextualization of the analogy, the surprising outcome of which is that Hume’s analogy is neither realist nor antirealist in spirit, but quietist. My argument has three parts. First, I reconstruct Hume’s argument (...) against rationalist moral ontology in Treatise 3.1.1, revealing his attention to the Intellectualism/Voluntarism debate in rationalism. Second, I present evidence of Hume’s familiarity with the debate between Intellectualist moral realists and Voluntarist moral antirealists, notably Pufendorf. Third, I establish that Hume’s analogy undermines a key assumption structuring that debate, and that the analogy consequently signals his quietist abstention from his rationalist contemporaries’ realism/antirealism debate in ethics.

The purpose of my paper is to discuss the issue of metaphysical anti-realism and its ‘anthropocentrism’, that is, the view according to which the species Homo sapiens is endowed with ontological pre-eminence over reality. The standard theory proposed by anti-realism suggests that one or more classes of objects depend on humans. This theory is contested by the fact – properly analyzed by Jacob von Uexküll – that other animals perceive the same objects as we do and get acquainted with them. (...) The idea underlying antirealism is that our way of perceiving reality is not only the best one, but also the only way possible. This incorrect belief is contested by modern science which shows how animals play the same role as humans in shaping the world, and furthermore, it represents a dangerous ethical drift that has to be firmly rejected, as I am going to affirm in the paper to follow.

This book explores the problem of realism, both metaphysical and scientific. Renowned specialists in the field - including Michael Devitt, David Papineau, Mark Sainsbury and Wesley Salmon - contribute new essays that shed new light on the main topics in the current realism/antirealism debate. Discussing a wide range of issues related to realism, both in metaphysics and in the philosophy of science, they address more specific questions including those concerning metaphysical realism, scientific realism, the relations between epistemology and ontology, (...) causation, dispositions and personal identity, and the relations between science and common sense. Presenting a comprehensive overview of the problem of realism, as well as in-depth discussion of particular topics, this book offers valuable insights for both students and researchers in the field. It can also be used in undergraduate and graduate courses of philosophy. (shrink)

This paper reviews the structure of standard quantum mechanics, introducing the basics of the von Neumann-Dirac axiomatic formulation as well as the well-known Copenhagen interpretation. We review also the major conceptual difficulties arising from this theory, first and foremost, the well-known measurement problem. The main aim of this essay is to show the possibility to solve the conundrums affecting quantum mechanics via the methodology provided by the primitive ontology approach. Using Bohmian mechanics as an example, the paper argues for a (...) realist attitude towards quantum theory. In the second place, it discusses the Quinean criterion for ontology and its limits when it comes to quantum physics, arguing that the primitive ontology programme should be considered as an improvement on Quine’s method in determining the ontological commitments of a theory.

Mental fictionalism holds that folk psychology should be regarded as a kind of fiction. The present version gives a Lewisian prefix semantics for mentalistic discourse, where roughly, a mentalistic sentence “p” is true iff “p” is deducible from the folk psychological fiction. An eliminativist version of the view can seem self-refuting, but this charge is neutralized. Yet a different kind of “self-effacing” emerges: Mental fictionalism appears to be a mere “parasite” on a future science of cognition, without contributing anything substantial. (...) The paper then rebuts the objection, illustrating that prefix semantics resolves a lingering problem for eliminativism from Boghossian. The problem is that eliminativists seem unable to adopt realism about neuroscience, for such realism implies that neuroscientific statements *represent* reality accurately. However, a deflationary version of prefix semantics allows the eliminativist to draw an ontologically relevant distinction (roughly) between truths that have a story-telling prefix and those that do not. (Deflationism means there is no implication that the unprefixed sentences robustly represent reality.) The overarching lesson is that eliminativists need to approach to ontology carefully so to avoid self-refutation; however, prefix semantical mental fictionalism provides the resources for them to do so.

Introduction to New Realism provides an overview of the movement of contemporary thought named New Realism, by its creator and most celebrated practitioner, Maurizio Ferraris. Sharing significant concerns and features with Speculative Realism and Object Oriented Ontology, New Realism can be said to be one of the most prescient philosophical positions today. Its desire to overcome the postmodern antirealism of Kantian origin, and to reassert the importance of truth and objectivity in the name of a new Enlightenment, has had (...) an enormous resonance both in Europe and in the US. Introduction to New Realism is the first volume dedicated to exposing this continental movement to an anglophone audience.Featuring a foreword by the eminent contemporary philosopher and leading exponent of Speculative Realism, Iain Hamilton Grant, the book begins by tracing the genesis of New Realism, and outlining its central theoretical tenets, before opening onto three distinct sections. The first, 'Negativity', is a critique of the postmodern idea that the world is constructed by our conceptual schemas, all the more so as we have entered the age of digitality and virtuality. The second thesis, 'positivity', proposes the fundamental ontological assertion of New Realism, namely that not only are there parts of reality that are independent of thought, but these parts are also able to act causally over thought and the human world. The third thesis, 'normativity,' applies New Realism to the sphere of the social world. Finally, an afterword written by two young scholars explains in more detail the relationship between New Realism and other forms of contemporary realism. (shrink)

This article presents a novel argument against a common principle of parsimony in philosophy. First, it identifies a widely employed principle of positive ontological parsimony, according to which we should, ceteris paribus, prefer smaller ontologies to larger ontologies. Next, it shows how this principle is used as part of a strategy by which to argue for antirealist positions in many subfields of philosophy: the ockhamistic antirealist strategy. Third, it argues that this principle commits its adherents to an implausible epistemological thesis—the (...) Eroding Ontology Thesis—according to which evidence for the existence of some entity is at least prima facie evidence against the existence of all other entities. Antirealists might decide to adopt a related position, ontological conservatism, according to which we should simply resist changing our ontology, but the article shows that it is independently unjustified. Therefore, it concludes, philosophers have good reason to cease employing one very common antirealist strategy. (shrink)

The aim of this study is to analyse the content of the interdisciplinary conversations in Göttingen between 1949 and 1961. The task is to compare models for describing reality presented by quantum physicists and theologians. Descriptions of reality in different disciplines are conditioned by the development of the concept of reality in philosophy, physics and theology. Our basic problem is stated in the question: How is it possible for the intramental image to match the external object?

In this paper, the elaboration of the concept of practical realist philosophy of science which began in the author's previous papers is continued. It is argued that practical realism is opposed to standard scientific realism, on the one hand, and antirealism, on the other. Standard scientific realism is challengeable due to its abstract character, as being isolated from practice. It is based on a metaphysical-ontological presupposition which raises the problem of the God's Eye point of view (as it was (...) called by Hilary Putnam). Joseph Rouse's conception of science as practice, Sami Pihlström's pragmatic realism, and even Ilkka Niiniluoto's critical scientific realism are interpreted as practical realist conceptions. Pihlström suggests that the contemporary scientific realist should be prepared to accept the pragmatically naturalized Kantian transcendental perspective on realism. It is argued, however, that this realistically naturalized Kantianism can be nothing more than practical realism, as originated by Karl Marx. (shrink)

Hermeneutical aspect of reference embraces a relation to reality in itsbroadest sense. This aspect of reference explains how some conceptsemployed in scientific theories and historical and fictional text, which areconsidered as “non-existant”, transform our experience of reality. Epistemologicalaspect of reference should not be separated from ontological andhermeneutical aspects.

Cognitive scientific realism as presented in my previous paper is amended to include a new and strong epistemic indicator for truth of scietific theories: theory coherence and by implication level coherence. Interestingly, this coherence exists despite the incommensurability of the ontology of different levels. Combined with empirical adequacy, theory coherence provides convincing arguments for the confutation of antirealist views. Specifically, fundamentalism, underdetermination, and instrumentalism are considered.

In the first part of the paper I argue that an ontology of events is precise, flexible and general enough so as to cover the three main alternative formulations of quantum mechanics as well as theories advocating an antirealistic view of the wave function. Since these formulations advocate a primitive ontology of entities living in four-dimensional spacetime, they are good candidates to connect that quantum image with the manifest image of the world. However, to the extent that some form of (...) realism about the wave function is also necessary, one needs to endorse also the idea that the wave function refers to some kind of power. In the second part, I discuss some difficulties raised by the recent proposal that in Bohmian mechanics this power is holistically possessed by all the particles in the universe. (shrink)

Although there are a host of distinct issues associated with discussions of realism and antirealism, the most fundamental is the ontological question whether there is a mind-independent world, a world with a determinate, intrinsic nature that is independent of our theoretical and practical interaction with it. That there is such a mind-independent world is the minimal and most crucial requirement of realism. The main purpose of this paper is to defend this ontological requirement of realism. The ontological requirement involves (...) two propositions---that objects exist whether or not they are known to exist, and that the world has an intrinsic nature that does not depend on our concepts, values, or interests. I defend realism against a number of objections offered by Putnam and Goodman. I argue that the ontological requirement of realism is not undermined by objections to it based upon a consideration of problems concerning reference, the implications of the “agent point of view,” the interest-relativity of concepts, or the multiplicity of versions of the world.

Structural realism has re-emerged as part of the debate between scientific realism and antirealism. Since then it has branched into several different versions, notably epistemic structural realism and ontic structural realism. The latter theory is still an important perspective in the realism/antirealism dialectic; however, its significance has expanded well beyond that debate. Today ontic structural realism is also an important player in the metaphysics of science literature, engaging with a variety of ontological questions. One of these pertains to (...) the basic categories of ontology, with the proponents of ontic structural realism typically advocating a radical rethinking of how to view substance and relation while calling into question the traditional privileging of the former over and against the latter. In this paper I assess ontic structural realism from the perspective of two major systems: Thomism and Scotism. I argue that the basic commitments of Thomism allow for some surprising convergences with ontic structural realism, while Scotism does not. (shrink)

In “The Natural Ontological Attitude,” Arthur Fine attempts to provide a way out of the realist/antirealist dichotomy in philosophy of science. Says Fine, the natural way of treating the ontological status of theoretical entities is not to form speculative metaphysical theories, be they realist or antirealist, but instead is to apply a homely version of Tarskian semantics. I argue that Fine’s position depends on two deficient maxims, and therefore does not provide a compelling way out of the realist/antirealist dichotomy. Fine’s (...) Maxim (FM) prohibits the possibility of inferring justified metaphysical theses from the truth-value of existence claims. Hilbert’s Maxim (HM) asserts that metatheoretic arguments are cogent only if they adhere to stricter standards than their constituent theories. I argue that (FM) is likely false, but even if true cannot be rationally believed. I further argue that (HM) is a deficient standard for theory justification due to the problem of infinite regress.

In this essay I try to give some overall statements in order to show that new realism is to be understood as a kind of positive philosophy. Against constructivism, I argue that there is a prevalence of the objects themselves on our understanding of them because reality offers a resistance to our attempt to grasp it depending on its level of dependence from our own understanding, which is different in the case of natural objects, ideal object and social object. This (...) negativity leads to an ontological necessity of facticity. In the second part of this paper I will describe – through the exposition of three key concepts of new realism, i.e. “unamendability”, “interaction” and “affordance” – an ascending path for which the negative and the resistance turn into positivity.

After a brief presentation of the Verisimilitudinarian approach to scientific progress, I argue that the notion of estimated verisimilitude is too weak for the purposes of scientific realism. Despite the realist-correspondist intuition that inspires the model—the idea that our theories get closer and closer to ‘the real way the world is’—, Bayesian estimations of truthlikeness are not objective enough to sustain a realist position. The main argument of the paper is that, since estimated verisimilitude is not connected to actual verisimilitude, (...) the way the Verisimilitudinarian account works is not in the end different from other antirealist accounts. Finally, I briefly present Alexander Bird’s cumulative approach to scientific progress, and argue that it has a similar problem; Bird has in mind truth in the correspondence sense, but all the metaphysical weight is put on the notion of ‘approximate truth’—whose connection to ‘the real way the world is’ is not clear.

We discuss the philosophical implications of formal results showing the con- sequences of adding the epsilon operator to intuitionistic predicate logic. These results are related to Diaconescu’s theorem, a result originating in topos theory that, translated to constructive set theory, says that the axiom of choice (an “existence principle”) implies the law of excluded middle (which purports to be a logical principle). As a logical choice principle, epsilon allows us to translate that result to a logical setting, where one can (...) get an analogue of Diaconescu’s result, but also can disentangle the roles of certain other assumptions that are hidden in mathematical presentations. It is our view that these results have not received the attention they deserve: logicians are unlikely to read a discussion because the results considered are “already well known,” while the results are simultaneously unknown to philosophers who do not specialize in what most philosophers will regard as esoteric logics. This is a problem, since these results have important implications for and promise signif i cant illumination of contem- porary debates in metaphysics. The point of this paper is to make the nature of the results clear in a way accessible to philosophers who do not specialize in logic, and in a way that makes clear their implications for contemporary philo- sophical discussions. To make the latter point, we will focus on Dummettian discussions of realism and anti-realism. Keywords: epsilon, axiom of choice, metaphysics, intuitionistic logic, Dummett, realism, antirealism.

Tim Button explores the relationship between words and world; between semantics and scepticism. -/- A certain kind of philosopher – the external realist – worries that appearances might be radically deceptive. For example, she allows that we might all be brains in vats, stimulated by an infernal machine. But anyone who entertains the possibility of radical deception must also entertain a further worry: that all of our thoughts are totally contentless. That worry is just incoherent. -/- We cannot, then, be (...) external realists, who worry about the possibility of radical deception. Equally, however, we cannot be internal realists, who reject all possibility of deception. We must position ourselves somewhere between internal realism and external realism, but we cannot hope to say exactly where. We must be realists, for what that is worth, and realists within limits. -/- In establishing these claims, The Limits of Realism critically explores and develops several themes from Hilary Putnam’s work: the model-theoretic arguments; the connection between truth and justification; the brain-in-vat argument; semantic externalism; and conceptual relativity. The book establishes the continued significance of these topics for all philosophers interested in mind, logic, language, or the possibility of metaphysics. (shrink)

I look at the distinction between between realist and antirealist views of the quantum state. I argue that this binary classification should be reconceived as a continuum of different views about which properties of the quantum state are representationally significant. What's more, the extreme cases -- all or none --- are simply absurd, and should be rejected by all parties. In other words, no sane person should advocate extreme realism or antirealism about the quantum state. And if we focus (...) on the reasonable views, it's no longer clear who counts as a realist, and who counts as an antirealist. Among those taking a more reasonable intermediate view, we find figures such as Bohr and Carnap -- in stark opposition to the stories we've been told. (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)
