Metaphysical Realism

Donald Hoffman proposed a bold theory—that objects do not exist independently of us perceiving them and that all that really exists is conscious agents. In this critical review, Leslie Allan examines the three core components of Hoffman's new idealism. He proposes solutions to linguistic absurdities suffered by Hoffman's theory before considering its most serious problems. These include oversimplifications of evolutionary theory, self-refutation, heuristic sterility and dependence on scientific realism.

There is a persisting debate about what chemical bonds are and whether they exist. I argue that chemical bonds are real patterns of interactions between subatomic particles. This proposal resolves the problems raised in the context of existing understandings of the chemical bond and provides a novel way to defend the reality of chemical bonds.

In this article, I analyze Charles Crittenden’s account of fictional objects in his Unreality: The Metaphysics of Fictional Objects (1991). I argue that Crittenden’s sketchy ontology of fictional objects does not support his weak eliminativism. Going along the lines of Amie Thomasson (1999), I stress that the problem of fictional objects is a strictly ontological problem, which requires an ontological solution. A solution to the problem of fictional objects (or ficta) that accommodates “practice” (ordinary language and literary practices) is of (...) course to be praised, but not when it is foregrounded at the expense of “ontology.” I argue for Roman Ingarden as a champion of ontology and practice, whose way of dealing with ficta fares better than Crittenden’s on both the ontological and practical sides. In short, ficta should be approached as something over and above mere grammaticalia (grammatical objects) namely as “purely intentional” objects that are formally incomplete, and which readers complete by resorting to practices of language and literary criticism.

Explanatory metaphysics aspires to explain the less fundamental in terms of the more fundamental. But we should recognize two importantly different approaches to this task. According to the generation approach, more basic features of reality generate (or give rise to) less basic features. According to the reduction approach, less perspicuous ways of representing reality reduce to (or collapse into) more perspicuous ways of representing reality. The main goals of this paper are to present the core differences between the two approaches (...) (§2), to demonstrate the distinction's significance (§3), to provide some resources for adjudicating between the approaches (§4), and to argue that the project of explanatory metaphysics needs both (§5).

Commitment to sparseness amounts to the idea that there is an objective, worldly privileging of certain properties over others that makes the privileged properties suited to play certain roles, and is responsible for their playing such roles. In this chapter I offer a brief, opinionated overview of sparseness. I begin by examining a set of problems that I call “problems of abundance”, which generate canonical motivations for sparseness. I then survey some influential approaches to sparseness and the roles that they (...) attribute to sparse properties, noting that on most approaches sparse properties are deeply connected to inquiry. Finally I consider some problems for sparseness, focusing on the purported connections between sparseness and inquiry, particularly in philosophy of science and inquiry into the social world.

Dasgupta poses a serious challenge to realism about natural properties. He argues that there is no acceptable explanation of why natural properties deserve the value realists assign to them and are consequently absent of value. In response, this paper defines and defends an alternative non-explanatory account of normativity compatible with realism. Unlike Lewis and Sider, who believe it is sufficient to defend realism solely on realist terms, I engage with the challenge on unfriendly grounds by revealing a tu quoque. Dasgupta (...) and anti-realists face a similar challenge to that directed against realism: one that not only undermines the objection to realism by legitimising non-explanatory normativity but leaves them facing a significant dilemma.

I propose that metaphysical study is initially indifferent to the truth of Metaphysical Realism about Metaphysics (MRM) and Metaphysical Realism and does not presuppose them. Metaphysical Realism is a metaphysical doctrine the truth of which cannot be settled logically prior to metaphysical investigation. MRM presupposes Metaphysical Realism and therefore, one should not hold MRM uncritically. An epistemological consequence of this is that arguments against the possibility of cognition about metaphysically real entities (by e.g., Hume) are not arguments against the epistemic (...) legitimacy of metaphysics without further arguments for MRM. This paper is also a case study of the philosophical significance of having rich enough acquaintance with the history of philosophy, the recent history included. (shrink)

Husserl’s allegiance to realism came under attack following his Ideas. Ingarden was a fierce critic of his teacher’s turn to transcendental idealism and provided compelling arguments both for his idealist reading of Husserl and for his rejection of idealism. One of the main arguments Ingarden devised against Husserl’s turn was based on his aesthetics. Against Husserl, Ingarden established literary works and fictional objects as purely intentional objects that are (1) doubly structured, vis-à-vis their formal ontology, and (2) endowed with spots (...) of indeterminacy. These facts, Ingarden argues, necessitate the transcendence of the purely intentional object. In this paper, I explore his argument, while establishing the ontological foundation on which it rests.

Amie Thomasson’s work provides numerous ways to rethink and improve our approach to metaphysics. This chapter is my attempt to begin to sketch why I still think the easy approach leaves room for substantive metaphysical work, and why I do not think that metaphysics need rely on any ‘epistemically metaphysical’ knowledge. After distinguishing two possible forms of deflationism, I argue that the easy ontologist needs to accept (implicitly or explicitly) that there are worldly constraints on what sorts of entities could (...) exist, and could co-exist. I argue this leaves room for a substantive role for metaphysics if (following the work of E.J. Lowe) we take metaphysics to be concerned with the possible ways that reality could be. I explain how this conception does not need to appeal to any ‘epistemically metaphysical’ knowledge, and need only make use of conceptual and/or empirical means to arrive at views on what could exist (and co-exist). Thus, the answer I propose to the question posed in the title, at least in my view, is no-one. Or, at least, no-one should be afraid of conceptual analysis. Not even metaphysicians. (shrink)

A discussion of the sense in which reality is mind-dependent for Kant and for David Lewis. Plus a lot about space-aliens (and a bit about pimple-worms).

This article introduces a non‐cognitivist account of metaphysical explanation according to which the core function of judgements of the form ⌜x because y⌝ is not to state truth‐apt beliefs. Instead, their core function is to express attitudes of commitment to, and recommendation of the acceptance of certain norms governing interventional conduct at contexts.

Logical realism is a view about the metaphysical status of logic. Common to most if not all the views captured by the label ‘logical realism’ is that logical facts are mind- and language-independent. But that does not tell us anything about the nature of logical facts or about our epistemic access to them. The goal of this paper is to outline and systematize the different ways that logical realism could be entertained and to examine some of the challenges that these (...) views face. It will be suggested that logical realism is best understood as a metaphysical view about the logical structure of the world, but this raises an important question: does logical realism collapse into standard metaphysical realism? It will be argued that this result can be accommodated, even if it cannot be altogether avoided. (shrink)

The objectively best language is intended to refer to some metaphysically privileged language that ‘carves reality at its joints’ perfectly. That is, it is the kind of language that various ‘metaphysical deflationists’ have argued is impossible. One common line of argument amongst deflationists is that we have no means to compare languages that all express true facts about the world in such a way to decide which is ‘better’. For example, the language is physics is not objectively better than the (...) language of economics, as each language has the semantic purpose of expressing some domain of truths about the world inexpressible in the other language, and therefore neither could be ‘objectively best’. In this paper, I argue that metaphysical deflationists have failed to recognise a distinction between fine- and coarse-grained semantic purposes of languages, and that a recognition of that distinction provides us grounds to compare languages to see which is objectively best. I argue that once we recognise the distinction between fine- and coarse-grained semantic purposes, then we can see that it is relative to the coarse-grained purpose that we must compare putative objectively best ontological languages.

Bedau's influential (1997) account analyzes weak emergence in terms of the non-derivability of a system’s macrostates from its microstates except by simulation. I offer an improved version of Bedau’s account of weak emergence in light of insights from information theory. Non-derivability alone does not guarantee that a system’s macrostates are weakly emergent. Rather, it is non-derivability plus the algorithmic compressibility of the system’s macrostates that makes them weakly emergent. I argue that the resulting information-theoretic picture provides a metaphysical account of (...) weak emergence rather than a merely epistemic one. (shrink)

The perennial nature of some of philosophy’s deepest problems is a puzzle. Here, one problem, the realism–anti-realism debate, and one type of explanation for its longevity, are examined. It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In the following sections, the dialetheic conclusion (...) is directly argued for by showing how realism and anti-realism satisfy Priest’s “inclosure schema”. In the last section and the conclusion, the conscious mind’s role in creating realism and anti-realism is discussed. This role further supports the conclusion that realism and anti-realism form a dialetheic pair. (shrink)

In modern Anglo-European philosophy there is a distinct progression from the metaphysical realism of ancient and classical philosophy towards a type of scepticism that eventually leads towards nihilism. Interestingly this progression also appears in the doctrines of the Classical schools of Indian Buddhism that pre-date modern European philosophy by well over six centuries. This progression stems from the application of the same types of logical and philosophical reasoning to the problems of metaphysics. The movement from metaphysical realism to representationalism to (...) idealism and finally towards nihilism, which is seen within both the classical Indian Buddhist tradition and Modern Anglo-European philosophy, are products of a coherent and wholly logical progression from the acceptance of certain metaphysical principles. The fact that these same movements occur in two philosophical traditions that are separated by vast chasms in space, time and culture seems to point to an underlying commonality underlying human philosophical enquiry, whether this is a result of a common intelligible reality, an essential and universal human nature or both is a philosophical question we must continue to pursue.

Yleensä Wienin piirin loogista empirismiä kannattaneet filosofit mielletään antirealisteiksi. Tässä artikkelissa kuitenkin argumentoidaan, että piirin johtohahmo Moritz Schlick oli eräänlainen realisti myös nykystandardien valossa. Näin ollen – niin yllättävältä kuin se kuulostaakin – positivismi ja realismi ovat yhteensovitettavissa. Schlick tosin erotti kannattamansa empiirisen realismin jyrkästi metafyysisestä realismista, jota hän piti merkityksettömänä. Schlickin realismin esittelyn lisäksi artikkelissa tarkastellaan yleisellä tasolla hänen epistemologiaansa, kielifilosofiaansa ja metafysiikan kritiikkiään. Tekstissä pohditaan myös Schlickin suosiman realismin asemaa ja relevanssia nykyisessä realismikeskustelussa.

There has recently been a revival of interest in what truth is. For a long time, deflationism ruled the roost, telling us that there’s not much of metaphysical.

As is well known, Putnam changed his philosophical position on a number of occasions throughout his career. In this paper, I reconsider the position of internal realism which Putnam defended from the mid-1970’s until around 1990. The paper opens with a discussion of the position that Putnam called “metaphysical realism”, since his internal realism emerged out of a critique of that position. The paper then briefly presents the internal realist view as one which involves an epistemic conception of truth, as (...) well as an anti-realist metaphysical outlook on which objects depend on conceptual scheme. The paper then provides a survey of the key objections to internal realism which emerged in the ensuing debate with defenders of realism. The paper concludes with a brief consideration of the relevance of Putnam’s later adoption of a direct realist theory of perception with respect to the issue of realism. (shrink)

I happen to believe that though human experiences are to be characterized as pluralistic they are all rooted in the one reality. I would assume the thesis of pluralism but how could I maintain my belief in the realism? There are various discussions in favor of realism but they appear to stay within a particular paradigm so to be called “internal realism”. In this paper I would try to justify my belief in the reality by discussing a special use of (...) indexicals. I will argue for my indexical realism by advancing the thesis that indexicals can be used as an inter-agentic referential term. Three arguments for the thesis will be presented. The first argument derives from a revision of Kaplan-Kvart’s notion of exportation. Their notions of exportation of singular terms can be analyzed as intra-agentic exportation in the context of a single speaker and theirs may be revised so as to be an inter-agentic exportation in the context of two speakers who use the same indexicals. The second is an argument from the notion of causation which is specifically characterized in the context of inter-theoretic reference. I will argue that any two theories may each say “this” in order to refer what is beyond its own theory. Two theories address themselves to ‘this’ same thing though what ‘this’ represents in each theory turn out to be different objects all together. The third argument is an argument which is based on a possibility of natural reference. Reference is used to be taken mostly as a 3-place predicate: Abe refers an object oi with an expression ej. The traditional notion of reference is constructive and anthropocentric. But I would argue that natural reference is a reference that we humans come to recognize among denumerably many objects in natural states: at a moment mi in a natural state there is a referential relation among objects o1, o2, o3, . . , oj, o j+1, . . which interact to each other as agents of information processors. Natural reference is an original reference which is naturally given and to which humans are passive as we derivatively refer it by using ‘this’. (shrink)

This paper addresses the ontological status of the ontological categories as defended within E.J. Lowe’s four-category ontology (kinds, objects, properties/relations, and modes). I consider the arguments in Griffith (2015. “Do Ontological Categories Exist?” Metaphysica 16 (1):25–35) against Lowe’s claim that ontological categories do not exist, and argue that Griffith’s objections to Lowe do not work once we fully take advantage of ontological resources available within Lowe’s four-category ontology. I then argue that the claim that ontological categories do not exist has (...) no undesirable consequences for Lowe’s brand of realism. (shrink)

This article examines whether it is possible to uphold one form of deflationism towards metaphysics, ontological pluralism, whilst maintaining metaphysical realism. The focus therefore is on one prominent deflationist who fits the definition of an ontological pluralist, Eli Hirsch, and his self-ascription as a realist. The article argues that ontological pluralism is not amenable to the ascription of realism under some basic intuitions as to what a “realist” position is committed to. These basic intuitions include a commitment to more than (...) a stuff-ontology, and a view that realism carries with it more than a rejection of idealism. This issue is more than merely terminological. The ascription of realism is an important classification in order to understand what sorts of entities can be the truthmakers within a given theory. “Realism” is thus an important term to understand the nature of the entities that a given theory accepts into its ontology.

The Controversy over the Existence of the World (henceforth Controversy) is the magnum opus of Polish philosopher Roman Ingarden. Despite the renewed interest for Ingarden’s pioneering ontological work whithin analytic philosophy, little attention has been dedicated to Controversy's main goal, clearly indicated by the very title of the book: finding a solution to the centuries-old philosophical controversy about the ontological status of the external world. -/- There are at least three reasons for this relative indifference. First, even at the time (...) when the book was published, the Controversy was no longer seen as a serious polemical topic, whether it was disqualified as an archaic metaphysical pseudo-problem, or taken to be the last remnant of an antiscientific approach to philosophy culminating in idealism and relativism. Second, Ingarden’s reasoning on the matter is highly complex, at times misleading, and even occasionally faulty. Finally, his analysis is not only incomplete – Controversy being unachieved – but also arguably aporetic. -/- One may wonder, then, why it is still worth excavating this mammoth treatise to study an issue apparently no longer relevant to contemporary philosophy. Aside from historical and exegetical purposes, which are of course very interesting in their own right, Ingarden’s treatment of the Controversy remains one of the most detailed and ambitious ontological undertakings of the twentieth century. Not only does it lay out an incredibly detailed map of possible solutions to the Controversy, but it also tries to show why the latter is a genuine and fundamental problem that owes its hasty disqualification to various oversimplifications over the course of the history of philosophy. -/- In this chapter, I first give an overview of Ingarden’s method, which relies mainly on a combinatorial analysis. Then, I summarize his examination of possible solutions to the Controversy, and determine which ones can be ruled out on ontological grounds. Finally, I explain why this ambitious project ultimately leads to a theoretical impasse, leaving Ingarden unable to come up with a definitive solution to the Controversy – regardless of the fact that the book is unachieved. I argue that his analysis of the problem yields a more modest but nonetheless valuable result. (shrink)

The title of this paper reflects the fact truthmaking is quite frequently considered to be expressive of realism. What this means, exactly, will become clearer in the course of our discussion, but since we are interested in Armstrong’s work on truthmaking in particular, it is natural to start from a brief discussion of how truthmaking and realism appear to be associated in his work. In this paper, special attention is given to the supposed link between truthmaking and realism, but it (...) is argued that this link should not be taken too seriously, as truthmaking turns out to be, to a large extent, ontologically neutral. Some consequences of this are studied. (shrink)

Hilary Putnam’s BIV argument first occurred to him when ‘thinking about a theorem in modern logic, the “Skolem–Löwenheim Theorem”’ (Putnam 1981: 7). One of my aims in this paper is to explore the connection between the argument and the Theorem. But I also want to draw some further connections. In particular, I think that Putnam’s BIV argument provides us with an impressively versatile template for dealing with sceptical challenges. Indeed, this template allows us to unify some of Putnam’s most enduring (...) contributions to the realism/antirealism debate: his discussions of brains-in-vats, of Skolem’s Paradox, and of permutations. In all three cases, we have an argument which does not merely defeat the sceptic; it also shows us that we must reject some prima facie plausible philosophical picture. (shrink)

Three influential forms of realism are distinguished and interrelated: realism about the external world, construed as a metaphysical doctrine; scientific realism about non-observable entities postulated in science; and semantic realism as defined by Dummett. Metaphysical realism about everyday physical objects is contrasted with idealism and phenomenalism, and several potent arguments against these latter views are reviewed. -/- Three forms of scientific realism are then distinguished: (i) scientific theories and their existence postulates should be taken literally; (ii) the existence of unobservable (...) entities posited by our most successful scientific theories is justified scientifically; and (iii) our best current scientific theories are at least approximately true. It is argued that only some form of scientific realism can make proper sense of certain episodes in the history of science. -/- Finally, Dummett’s influential formulation of semantic issues about realism considered. Dummett argued that in some cases, the fundamental issue is not about the existence of entities, but rather about whether statements of some specified class (such as mathematics) have an objective truth value, independently of our means of knowing it. Dummett famously argued against such semantic realism and in favor of anti-realism. The relation of semantic realism to the metaphysical construal of realism and Dummett’s main argument against semantic realism is examined. (shrink)

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)

Once it is appreciated that it is not possible for an all-powerful, all-knowing, all-loving God to exist, the important question arises: What does exist that is closest to, and captures the best of what is in, the traditional conception of God? In this paper I set out to answer that question. The first step that needs to be taken is to sever the God-of-cosmic-power from the God-of-cosmic-value. The first is Einstein’s God, the underlying dynamic unity in the physical universe which (...) physics seeks to depict by means of a true, unified, physical “theory of everything”. Science has already achieved some theoretical knowledge of this God-of-cosmic-power. The second is what is of most value in our human world, and in the world of sentient life more generally. Having cut God in half in this way, our fundamental problem, intellectual and practical, becomes: How can the God-of-cosmic-value (as it is represented on earth at least) exist and best flourish within the God-of-cosmic-power? Or, in other words: How can what is of value associated with human life – and sentient life more generally – exist and best flourish within the physical universe? Clearly acknowledging that this is our fundamental problem, in academic inquiry, and in all that we do, might help what is of value in life to flourish rather better than it does at present.

The early twentieth century witnessed the emergence of "objective relativism," a distinctly American school of metaphysical realism inspired by the works of John Dewey and A.N. Whitehead. Largely forgotten, objective relativism provided a metaphysical framework, based upon an ontology of events and relations rather than substances and discrete properties, that has continued relevance for contemporary metaphysical discussions. In this thesis, I attempt to chart the boundaries and pathways of this ontology, outlining what Dewey calls the "ground-map of the province of (...) criticism." In particular, the ground-map of objective relativism is invoked to situate and analyze the model of psycho-physical emergence outlined in Dewey's Experience and Nature. Because it is a relational ontology, objective relativism avoids problems with emergence common to substantival models. Additional analyses of its ontological premises, both in Dewey's writings and elsewhere, demonstrate how compelling accounts of causation, consciousness, and meaning may be formulated within this model.

There is good reason to believe that scientific realism requires a commitment to the objective modal structure of the physical world. Causality, equilibrium, laws of nature, and probability all feature prominently in scientific theory and explanation, and each one is a modal notion. If we are committed to the content of our best scientific theories, we must accept the modal nature of the physical world. But what does the scientific realist’s commitment to physical modality require? We consider whether scientific realism (...) is compatible with Humeanism about the laws of nature, and we conclude that it is not. We specifically identify three major problems for the best-systems account of lawhood: its central concept of strength cannot be formulated non-circularly, it cannot offer a satisfactory account of the laws of the special sciences, and it can offer no explanation of the success of inductive inference. In addition, Humeanism fails to be naturalistically motivated. For these reasons, we conclude that the scientific realist must embrace natural necessity. (shrink)

The aim of this essay is to provide an overview of New Realism in its opposition and reaction to Postmodernism. An analysis of the implications of both philosophical approaches in diverse fields will be offered, from epistemology, to politics, to ethics. Ethical new realism is presented as particularly promising and important to the future of philosophy.

This paper defends the idea that there must be some joints in reality, some correct way to classify or categorize it. This may seem obvious, but we will see that there are at least three conventionalist arguments against this idea, as well as philosophers who have found them convincing. The thrust of these arguments is that the manner in which we structure, divide or carve up the world is not grounded in any natural, genuine boundaries in the world. Ultimately they (...) are supposed to pose a serious threat to realism. The first argument that will be examined concerns the claim that there are no natural boundaries in reality, the second one focuses on the basis of our classificatory schemes, which the conventionalist claims to be merely psychological, and the third considers the significance of our particular features in carving up the world, such as physical size and perceptual capabilities. The aim of this paper is to demonstrate that none of these objections succeed in undermining the existence of genuine joints in reality. (shrink)

Truthmaker theory begins with the idea that truth depends upon reality. When a truth-bearer is true, that is because something or other in the world makes it true. My dissertation offers a theory of truthmakers that shows how we should flesh out this thought while avoiding the contentious metaphysical commitments that are built into other truthmaker theories. Because of these commitments, many philosophers have come to view truthmaker theory as being essentially tied to correspondence theories of truth, and to metaphysical (...) realism. I argue that, quite to the contrary, truthmaker theory is distinct from correspondence theory, and that the former actually undermines the motivation for the latter. In fact, truthmaker theory can be used to argue for a particular kind of deflationism about truth. I also argue that debates about realism and anti-realism are best viewed through the lens of truthmaker theory, which is not—contrary to what many have thought—an essentially realist approach to metaphysics. Anti-realists of various stripes can also make use of truthmakers. The anti-realism of such views depends upon either the nature of the truthmakers they use, or the nature of the truthmaking relation itself. (shrink)

This thesis vindicates the common-sense intuition that touch is more objective than the other senses. The reason why it is so, it is argued, is that touch is the only sense essential of the experience of physical effort, and that this experience constitutes our only acquaintance with the mind-independence of the physical world. The thesis is divided in tree parts. Part I argues that sensory modalities are individuated by they proper objects, realistically construed. Part II argues that the proper objects (...) of touch are pressures and tensions, defined as pairs of real and antagonist forces. Part III argues that experiences of pressures are an essential part of the experience of physical effort and that the experience of physical effort (which amounts to the experience of resistance to our will), constitutes our only immediate access to the mind-independence of the physical world.

When talking about truth, we ordinarily take ourselves to be talking about one-and-the-same thing. Alethic monists suggest that theorizing about truth ought to begin with this default or pre-reflective stance, and, subsequently, parlay it into a set of theoretical principles that are aptly summarized by the thesis that truth is one. Foremost among them is the invariance principle.

In the sixth chapter of The View from Nowhere, Thomas Nagel attempts to identify a form of idealism. The position that he deems idealist is that what there is must be possibly conceivable by us. Nagel claims that this position is held by a number of contemporary philosophers. Even if this is so, I justify the view that it is not a form of idealism.

The goal of this article is twofold. First, it revises the historiographic partition proposed by John Deely in Four Ages of Understanding (2001) by arguing that the moment marking the beginning of philosophical Modernity has been vividly recorded in Descartes’ Meditations on First Philosophy with the experiment with the wax. Second, an upshot of this historical study is that it helps make sense of Deely’s somewhat iconoclastic use of the words “subject” and “subjectivity” to designate mind-independent worldly things. The hope (...) is that successfully accomplishing these twin tasks will give semiotic inquiry a better appreciation of its own history, as well as resources genial to furthering its ongoing development.

The paper will have three sections. In section one I briefly present and respond to Byrne’s argument against theological realism. In section two, I present van Fraassen’s argument against analytic metaphysics and I show how, if sound, it constitutes a reason to reject both metaphysical and theological realism. In section three, I show how van Fraassen can be answered. Obviously what I am doing here falls far short of a full-blown defense of realism in either metaphysics or theology. But the (...) objections raised by van Fraassen and Byrne are tokens of a type of objection that I think is rather widely endorsed among those who are suspicious of these two brands of realism. Thus, responding to those objections constitutes an important first step in the direction of a defense. (shrink)

Structured around Charles S. Peirce's three-fold categorical scheme, this article proposes a comparative study of Ayn Rand and Peirce's realist views in general metaphysics. Rand's stance is seen as diverging with Peirce's argument from asymptotic representation but converging with arguments from brute relation and neutral category. It is argued that, by dismissing traditional subject-object dualisms, Rand and Peirce both propose iconoclastic construals of what it means to be real, dismissals made all the more noteworthy by the fact each chose to (...) ground them in indissoluble triads of self-evident first principles.

This paper examines Hilary Putnam’s arguments against what he calls metaphysical realism and in favour of internal realism. A key notion is the one of conceptual scheme, whose role is to explain how we inevitably find ourselves adopting one viewpoint among possible others. To ensure the possibility of agreement between all inquirers for some basic issues, is Putnam committed to having just one conceptual scheme for all human inquirers? The paper argues that the answer is no, on condition that all (...) inquirers are assumed to have a kind of cognitive faculty that is common to all. (shrink)

This book is a new attempt to clarify what is at issue in the contemporary realism debates and to suggest which form the controversies ought to take. Wright has contributed to the-se debates for quite some time and essentially taken the anti-realist side (witness the papers collected in Realism, Meaning and Truth, 1987, 21993, and the forthcoming Realism, Rules and Objectivity, both Oxford: Basil Blackwell). In Truth and Objectivity however, he takes a step back and sketches a neutral ground upon (...) which both sides could agree in or-der to define their oppositions clearly, thus enabling fruitful discussions. His methodolog-ical suggestion for a realism debate in a given assertoric discourse is that both sides should agree on a “minimal” concept of truth for that discourse and then see whether ascent to a more metaphysically substantial concept of truth is warranted, which would constitute a realism for the discourse in question. If Wright had managed to set the agenda in a way that does justice to both sides, this book would have constituted a major contribution to contemporary epistemology and metaphysics. (shrink)

There is a dogma about metaphysical realism that is well nigh universal: "If one is a metaphysical realist about the external world, then one ought to be a semantic realist about external- world statements". I argue that this dogma should be rejected. It is possible for a metaphysical realist to be a "semantic dualist", holding that some middle- sized object statements receive a realist interpretation, but that most such statements require an antirealist interpretation. To show that a semantically dual language (...) is at least possible, I describe a possible world whose inhabitants speak a version of English that is syntactically dual. Further I argue that English in the "actual world" is itself semantically dual. (shrink)

Article on mental causation and metaphysical realism.

The critical focus of this paper is on a claim made explicitly by Gilbert Harman and accepted implicitly by numerous others, the claim that naturalism supports concurrent defense of scientific objectivism and moral relativism. I challenge the assumptions of Harman's ‘argument from naturalism' used to support this combination of positions, utilizing. Hilary Putnam’s ‘companions in guilt’ argument in order to counter it. The paper concludes that while domain-specific anti-realism is often warranted, Harman’s own views about the objectivity of facts and (...) the subjectivity of values are better seen as stemming from scientistic ideals of knowledge than from dictates of naturalism. Scientists qua scientists make value judgments, and setting aside scientistic assumptions and unrealizable conceptions of scientific objectivity should lead us to more symmetrical metaphilosophical conception of epistemic and ethical normativity than that which underlies Harman's account.

Failure to recognize the "realistic" motivations for Putnam's commitment to internal realism has led to a widely shared misunderstanding of Putnam's arguments against metaphysical realism. Realist critics of these arguments frequently offer rebuttals that fail to confront his arguments. Simply put, Putnam's arguments --the brains in a vat argument as well as the model-theoretic argument -- are "reductios" that are intended to show that "metaphysical realism itself is not sufficiently realistic". If that claim can be substantiated then Putnam can go (...) on to argue that his own view is, by comparison, more realistic than metaphysical realism. (shrink)
