Metaphysical Realism

A significant ontological commitment is required to sustain metaphysical realism—the view that there is a single, objective way the world is—in order to defend it from common sense objections. This involves presupposing the existence of properties (or tropes, or universals) and relations between them which define the objective structure of the world. This paper explores the grounds for accepting this ontological assumption and examines a sceptical argument which questions whether, having assumed the world is objectively divided into fundamental properties, we (...) could ever know which properties these are. It then assesses the responses available to the metaphysical realist, arguing that the sceptical difficulty cannot merely be dismissed by means of another assumption in the manner of radical scepticism, as David Lewis suggests, but that the sceptic's argument might be defused by the non-question-begging success of some form of strong scientific realism which links the predicates of our scientific theories directly to the fundamental properties the world contains. It remains unclear however whether this widely accepted metaphysical theory can find principled philosophical support. (shrink)

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)

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)

This paper juxtaposes the thought of Carl G. Jung to that of Giambattista Vico , aiming primarily at overturning all currently dominant historicist readings of Vico's political philosophy. On the way, I illuminate Vico's rational or non-dogmatic response to both medieval Christian theology and modern "scientific" philosophy . The Vico emerging through his own arguments and "reasoning" is a reviver of political philosophy in the Socratic tradition of Plato and Cicero.

Realism and anti-realism about a domain of thought are metaphysical theses that involve the natures of the truthmakers in that domain and the truthmaking relation that is operant in the domain. Truthmaker theory is not exclusive territory for realists: anti-realist views are also best understood in terms of how they understand truthmakers and truthmaking. In particular, I explore the possibility of projectivist truthmaking, and show how it makes sense of quasi-realism. In addition to critically examining some extant accounts of the (...) relationship between realism and truthmaking, I offer an account that best captures the nature of the various realism debates. (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)

According to Fine (among others), a nonbasic factual proposition must be grounded in facts involving those of its constituents that are both real and fundamental. But the principle is vulnerable to several dialectically significant counterexamples. It entails, for example, that a logical Platonist cannot accept that true disjunctions are grounded in the truth of their disjuncts; that a Platonist about mathematical objects cannot accept that sets are grounded in their members; and that a color primitivist cannot accept that an object’s (...) being scarlet grounds its not being chartreuse. The Finean might try to defend these implications, but it generates further problems. Instead, the principle should be rejected. An important upshot is that the principle cannot be relied on, as it has been, to distinguish robust realists from anti-realists about a propositional domain—the principle obscures ways of taking features to be both real and fundamental.

Karol Wojtyła (Pope John Paul II) found phenomenology very helpful for the analysis of concrete human experience and for overcoming the ethical formalism ofKant. Phenomenology, he believed, could also enrich classical Thomism by exploring the lived experience of freedom, interiority, and self-governance. But phenomenology, in his opinion, needed to be supplemented by metaphysics in order to ground experiences such as the sense of duty in the real order. He criticized much modern philosophy for abandoning metaphysics and thus neglecting the sapiential (...) dimension. Since his career as a professor was very short, he did not have time to complete his project of a personalist Thomism in which phenomenology and metaphysics would be harmoniously combined. (shrink)

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.

This dissertation concerns Putnam's objections to the realist conception of truth and his alternative, "internal realist," conception. I evaluate two main kinds of argument that Putnam advances against the realist conception of truth. First, the realist conception requires that we are talking about a kind of world we could never, according to Putnam, be talking about, namely a world that exists in itself, independent of minds. He argues that our powers of representation could never establish the right kind of connection (...) to such a world. I argue that while Putnam's arguments against the "moderate" version of metaphysical realism are successful, his arguments against the more extreme, "rationalist" version of metaphysical realism are not. ;Second, the realist conception of truth requires that we are talking about a kind of world that we could, in yet another way, never be talking about, not now because of limitations on our powers of representation, but rather because the world that we do in fact talk about has the character of being conditioned by our interests in a way that is incompatible with it existing in itself, independent of mind. Since Putnam's arguments on this point are strongly verificationist, without an independent defense of verificationism, they are weak. But since verificationism cannot be easily dismissed, these arguments have some intuitive appeal. Thus, while they do not refute the realist conception of truth, they raise important doubts about it. ;The final part of the dissertation explores Putnam's alternative conception, appealing to "idealized rational acceptability," as a kind of correspondence theory of truth, according to which a belief is true just in case it corresponds to constructed, not mind-independent, reality. Making clear sense of how reality can be mind-dependent, but still real is a difficult problem. Putnam rejects rationalism for its "magical" assumptions. I have argued that Putnam is committed to the existence of a world which is real and external to our minds, yet still somehow dependent on minds. This too begins to look magical. (shrink)

Lynne Rudder Baker presents and defends a unique account of the material world: the Constitution View. In contrast to leading metaphysical views that take everyday things to be either non-existent or reducible to micro-objects, the Constitution View construes familiar things as irreducible parts of reality. Although they are ultimately constituted by microphysical particles, everyday objects are neither identical to, nor reducible to, the aggregates of microphysical particles that constitute them. The result is genuine ontological diversity: people, bacteria, donkeys, mountains and (...) microscopes are fundamentally different kinds of things - all constituted by, but not identical to, aggregates of particles. Baker supports her account with discussions of non-reductive causation, vagueness, mereology, artefacts, three-dimensionalism, ontological novelty, ontological levels and emergence. The upshot is a unified ontological theory of the entire material world that irreducibly contains people, as well as non-human living things and inanimate objects. (shrink)

On September 11, 2001, as everyone knows, the towers of the World Trade Center in New York were attacked. I want to discuss this event in order to motivate a nonreductionist view of the extensions of everyday concepts. Next, I shall set out, and begin to defend, the particular view of nonreductionism that I favor—the Constitution View. Then, I shall consider two venerable metaphysical issues (the nature of vagueness and the mind-independent/mind- dependent distinction) in light of the Constitution View. If (...) the Constitution View is correct, then everyday concepts are a good guide to reality. My aim is to offer a metaphysical theory that acknowledges the genuine reality of what our everyday concepts (as well as our scientific concepts) are concepts of. (shrink)

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)

In this paper I present a transcendental argument based on the findings of cognitive psychology and neurophysiology which invites two conclusions: First and foremost, that a pre-condition of visual perception itself is precisely what the Aristotelian and other commonsense realists maintain, namely, the independent existence of a featured, or pre-packaged world; second, this finding, combined with other reflections, suggests that, contra McDowell and other neo-Kantians, human beings have access to things as they are in the world via non-projective perception. These (...) two conclusions taken together form the basis of Aristotelian metaphysical realism and a refutation of the neo-Kantian two-factor approach to perception. (shrink)

This paper explains the nature and origin of what I am calling Transgressive Realism, a middle path between realism and anti-realism which tries to combine their strengths while avoiding their weaknesses. Kierkegaard created the position by merging Hegel’s insistence that we must have some kind of contact with anything we can call real (thus rejecting noumena), with Kant’s belief that reality fundamentally exceeds our understanding; human reason should not be the criterion of the real. The result is the idea that (...) our most vivid encounters with reality come in experiences that shatter our categories, the way God’s commandment to kill Isaac irreconcilably clashes with the best understanding of ethics we are capable of. I explain the genesis of this idea, and then show it at work in Heidegger and Levinas’ thought. Understanding this position illuminates important aspects of the history of continental philosophy and offers a new perspective on realism. (shrink)

I am a realist of a metaphysical stripe. I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they comprise, (...) metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

This paper deals with the problem of the External World, taking its point of departure in Peter Zinkernagel's Conditions for Description. In the first section I try to give an outline of the theses contained in that book. In the second I raise a main objection against it, pointing out that Zinkernagel, in one respect, has not sufficiently sharpened the argumentation between phenomenalism and realism. In the third section I turn realism and phenomenalism sharply against each other, presenting the latter (...) in a radical, yet consistent form; the section is an attempt to show how phenomenalism can be rejected.

There are a bewildering variety of ways the terms "realism" and "anti-realism" have been used in philosophy and furthermore the different uses of these terms are only loosely connected with one another. Rather than give a piecemeal map of this very diverse landscape, the authors focus on what they see as the core concept: realism about a particular domain is the view that there are facts or entities distinctive of that domain, and their existence and nature is in some important (...) sense objective and mind-independent. The authors carefully set out and explain the different realist and anti-realist positions and arguments that occur in five key domains: science, ethics, mathematics, modality and fictional objects. For each area the authors examine the various styles of argument in support of and against realism and anti-realism, show how these different positions and arguments arise in very different domains, evaluate their success within these fields, and draw general conclusions about these assorted strategies. Error theory, fictionalism, non-cognitivism, relativism and response-dependence are taken as the most important positions in opposition to the realist and these are explored in depth. Suitable for advanced level undergraduates, the book offers readers a clear introduction to a subject central to much contemporary work in metaphysics, epistemology and philosophy of language.

J.D. Collier sees Putnam as arguing that metaphysical realism is false.' He sees the argument as proceeding from the background assumption that metaphysical realism has the consequence that truth is 'radically non-epistemic', so that 'an [epistemically] ideal theory could be radically wrong about the world' [3, p. 413]. But, according to Collier, Putnam argues that 'an ideal theory satisfying all of our methodological and theoretical constraints cannot be false' [3, p. 413]. Collier attempts to defend metaphysical realism against this Putnamian (...) attack by distinguishing 'between our ability to state a theory and our ability to conceive its possibility' [3, p. 413]. I will show that this defence is unsuccessful. (shrink)

Article on mental causation and metaphysical realism.

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)

Tim Button explores the relationship between minds, words, and world. He argues that the two main strands of scepticism are deeply related and can be overcome, but that there is a limit to how much we can show. We must position ourselves somewhere between internal realism and external realism, and we cannot hope to say exactly where.

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.

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.

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.

In 1974 Putnam was a ‘realist’ in regard to the physical world. By 1981 he had become a 'non-realist' in this regard. (I don’t know where he stands today.) In this paper I argue that his realism was more plausible than his non-realism. The physical world is what it is independently of any rational being’s interpretation of it.

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)

Ross & Spurrett (R&S) appear convinced that the world must have a unified ontological structure. This conviction is difficult to reconcile with a commitment to mainstream realism, which involves allowing that the world may be ontologically disunified. R&S should follow Kitcher by weakening their conception of unification so as to allow for the possibility of ontological disunity.

This volume develops and defends critical realism whilst engaging critically with existentialist philosophy in a number of ways. The work of existentialist thinkers as diverse as Kierkegarrd, R.D. Laing, Heideggar and Sartre is discussed at length and Andrew Collier argues that there is much to be learnt from their work, especially in Heidegger's critique of the technological view of the world. However the book concludes with a defence of objectivity against the various forms of subjectivism advanced by the existentialists.

Hilary Putnam and Nelson Goodman are two of the twentieth century's most persuasive critics of metaphysical realism, however they disagree about the consequences of rejecting metaphysical realism. Goodman defended a view he called irrealism in which minds literally make worlds, and Putnam has sought to find a middle path between metaphysical realism and irrealism. I argue that Putnam's middle path turns out to be very elusive and defend a dichotomy between metaphysical realism and irrealism.

Hilary Putnam's famous model-theoretic arguments have the virtue of presenting metaphysical realists with a clear challenge. On pain of embracing either an implausible antifallibilism or the radical indeterminacy of reference, metaphysical realists must appeal to metalinguistic levels of interpretation richer than our own in order to fix meaning. And sense must be made of this appeal. In this paper I begin the task of developing a version of metaphysical realism that takes up this challenge.

Horwich argues that we should reject metaphysical realism, but that we can preserve semantic realism by adhering to a redundancy theory of truth and a confirmationist account of linguistic understanding. But the latter will give us semantic realism only if it allows that the truth-values of sentences may transcend our recognitional capacities, and this is possible only insofar as we covertly reintroduce metaphysical realism. In spite of its intuitive appeal, we should not endorse semantic realism, but this need not bear (...) upon the tenability of scientific realism. (shrink)
