This Element is a survey of central topics in the metaphysics of material objects. The topics are grouped into four problem spaces. The first concerns how an object's parts are related to the object's existence and to the object's nature, or essence. The second concerns how an object persists through time, how an object is located in spacetime, and how an object changes. The third concerns paradoxes about objects, including paradoxes of coincidence, paradoxes of fission, and (...) the problem of the many. The fourth concerns views with radical consequences regarding the existence of composite material objects, including mereological nihilism, ontological anti-realism, and deflationism. (shrink)

Realism about material objects faces a variety of epistemological objections. Recently, however, some realists have offered new accounts in response to these long-standing objections; many of which seem plausible. In this paper, I raise a new objection against realism vis-à-vis how we could empirically come to know mind-independent essential properties for objects. Traditionally, realists hold kind-membership and persistence as bound together for purposes of tracing out an object’s essential existence conditions. But I propose kind-membership (...) and persistence for objects can conceptually come apart and function epistemologically distinctly from one another—in which case the usual reliance by realists on an assumption of persistence to determine kind-membership conditions is unjustified. Thus, present realist attempts to explain how empirical detection of mind-independent essential properties for objects could possibly occur inevitably results in circularity. The charge against the realist is to explain why we don’t have to first discover persistence conditions for an object before we can ascertain kind-membership conditions for an object. If no answer is forthcoming, then it seems the weight of the epistemological objection to realism is back in full force. (shrink)

What becomes of our clearest theories of explanation, when faced with the unpalatable quantum phenomena that seem to undermine the direct conceptual connection between the fundamental material entities and the self-standing material objects of everyday parlance? The general explanatory theory advocates unification of explanatory concepts with everyday discourse, identification of essentially similar characteristics between direct experience and the hypothesised explanatory ontology, and a conceptualisation of phenomena in terms of objects enduring causally regulated change. On the other (...) hand quantum theory feeds antirealist suspicions about the worth of realist explanatory endeavour with examples of phenomena in which the structure of material separation and individuation based on spatial extension is insufficient for construction of deeper explanatory narratives. An example from history of science, that of Newton’s law-constitutive definition of objects in response to D escartes problem of bodies is used to suggest a possible strategy for explanations unifying the quantum and common-sense conceptual domains, provided the anti-realist challenge to such enterprise is read as questioning the epistemological justification of interpretation of experience in both cases.Što se događa s najjasnijim dostupnim teorijama objašnjenja kada se suoče s problematičnim kvantnim pojavama koje naizgled potkopavaju neposrednu konceptualnu poveznicu između fundamentalnih materijalnih entiteta i samoopstojnih materijalnih predmeta iz svakodnevnog govora? Opća teorija objašnjenja preporuča objedinjenje teoretskih eksplanatornih pojmova sa svakodnevnim govorom, određenje esencijalno sličnih karakteristika između neposrednog iskustva i hipotetske eksplanatorne ontologije te konceptualizaciju pojava kroz predmete koji istraju kroz uzročno regulirane promjene. S druge strane, kvantna teorija potkrjepljuje antirealistične sumnje o valjanosti eksplanatornog nastojanja realizma primjerima pojava u kojima je struktura materijalne razdvojenosti i individuacije temeljene na prostornoj protežnosti nedovoljna za izgradnju dubljih eksplanatornih narativa. Primjerom iz povijesti znanosti, Newtonovom definicijom predmeta temeljenom na zakonima kao odgovorom na Descartesov problem materijalnih tijela, daje se moguća strategija izgradnje objašnjenja koja objedinjuju kvantne i “zdravorazumske” konceptualne domene, ukoliko se antirealistična kritika te izgradnje u oba slučaja shvati kao propitivanje epistemološkog opravdanja tumačenja iskustva.

In World Without Design: The Ontological Consequences of Naturalism, I argued that there is an important sense in which naturalism’s current status as methodological orthodoxy is without rational foundation, and I argued that naturalists must give up two views that many of them are inclined to hold dear—realism about material objects and materialism. In a review recently published in Faith and Philosophy, Dale Jacquette alleges that my arguments in World Without Design are directed mainly against strawmen (...) and that I have neglected to discuss at least one formulation of naturalism that straightforwardly addresses my main objections. In this reply, I show that these and other objections raised by Jacquette are unsound and, in fact, rest on egregious misrepresentations of the book. (shrink)

Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century; but Michael Rea claims that it is without rational foundation, and that the costs of embracing it are surprisingly high. Rea argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material objects, materialism, and perhaps realism about other minds. That is surely a price that naturalists are unwilling (...) to pay: this philosophical orthodoxy should be rejected. (shrink)

The ongoing duel between realist and anti-realist tendencies in film theory usually positions the ideas of André Bazin unambiguously on the realist side. Whatever else we expect to find in his writing – and the current resurgence is finding more and more – we should find this: realism, cinematic realism. But what type of realism? Is it ontological, and, if so, is it based on a claim for the primacy of photography's “analogical” relation to the world, even (...) to the point of a “direct contact” with the physical existence of nature? Is it aesthetic, celebrating depth of field? Unaffected mise-en-scène? The documentary impulse in preference to fantasy or artifice? In this article, however, I want to argue that we must expand the definition of Bazinian realism through its sensitivity to the non-human. The terrain of the cinematic “Real” is inhabited by a singular complex, one that includes physical space, animality, and material objects, as well as persons and events. To shift our attention to these elements and their effects – intimate as well as alienating, familiar as well as jarring and unexpected – offers another way to glimpse the Real. Which is not to say that the socially constituted world drops out. Of course, language, gender and culture are inescapable mediations. Yet they are, in a certain sense, all wrought by a transcendent human hand. Bazin's conception of realism provides access to a space that is less anthropocentric and testifies to an immanence of the Real, such that non-human, objective realism is not about capturing reality in toto but registering the fact that the human is only a part of reality. There are realities beyond human subjectivity – in space, in objects, in animality – realities that we are put in contact with by cinema. Ideally, what cinema makes possible is an equality, a democratic freedom, not merely for the human spectator – to view and explore film worlds – but for the viewed “object” too: a democracy of the viewer-viewed that installs intersubjectivity in the Real.

Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century; but Michael Rea claims that it is without rational foundation, and that the costs of embracing it are surprisingly high. The first part of World Without Design aims to provide a fair and historically informed characterization of naturalism. Rea then argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material (...) class='Hi'>objects, materialism, and perhaps realism about other minds. This conclusion is striking, largely because naturalism is often simply identified with materialism, and the remaining two theses are ones that naturalists very typically want to endorse. Rea goes on to examine two alternative research programs: intuitionism and supernaturalism, and argues for the conclusion that intuitionism, under certain circumstances, is self-defeating.World Without Design offers a provocative challenge to philosophical orthodoxy. It will make uncomfortable reading for many philosophers. (shrink)

There is an overlooked similarity between three classic accounts of the conditions of object experience from three distinct disciplines. Sociology: the “inversion” that accompanies discovery in the natural sciences, as local causes of effects are reattributed to an observed object. Psychology: the “externalization” that accompanies mastery of a visual–tactile sensory substitution interface, as tactile sensations of the proximal interface are transformed into vision-like experience of a distal object. Biology: the “projection” that brings forth an animal’s Umwelt, as impressions on its (...) body’s sensory surfaces are reconfigured into perception of an external object. This similarity between the effects of scientific practice and interface-use on the one hand, and of sensorimotor interaction on the other, becomes intelligible once we accept that skillful engagement with instruments and interfaces constitutes a socio-material augmentation of our basic perceptual capacity. This enactive interpretation stands in contrast to anti-realism about science associated with constructivist interpretations of these three phenomena, which are motivated by viewing them as the internal mental construction of the experienced object. Instead, it favors a participatory realism: the sensorimotor basis of perceptual experience loops not only through our body, but also through the external world. This allows us to conceive of object experience in relational terms, i.e., as one or more subjects directly engaging with the world. Consequently, we can appreciate scientific observation in its full complexity: it is a socio-materially augmented process of becoming acquainted with the observed object that—like tool-use and perceiving more generally—is irreducibly self, other-, and world-involving.

The central argument of The Quest for Reality is that of Ch. 7, to show that an anti-realist rejection of colours could never be asserted without a kind of self-refutation; that view is consequently ‘no threat’ to everyday colour beliefs. There are people these arguments have not convinced; but my present interest lies in a turn which occurs later in the book, where Stroud insists it remains in some sense a ‘possibility’ that our everyday colour beliefs might still be false: (...) there might ‘really’ be no colours. Stroud emerges therefore in a middle ground between what we might call dogmatic anti-realism and dogmatic realism. His position might even be called a form of reluctant scepticism—though on the ancient model more than the modern, recommending that we ‘live by appearances’ and abandon dogma: we know in any ordinary way that grass is green and tomatoes red, but ‘the metaphysical question about the reality of colour’ remains unsettled—indeed, it seems, permanently beyond us. The ‘scepticism’ about colour here, I think, bears comparison with the limited scepticism about material objects in Stroud’s earlier book The Significance of Philosophical Scepticism. However, I shall argue that even in the case of material objects, such scepticism seems compulsory only because another option is simply passed over; and in the case of colour, the scepticism is one degree less coherent than in the case of material objects.

A not-unpopular position in the metaphysics of material objects (Ted Sider's, for instance) combines realism about what objects there are and the conditions of objecthood with conventionalism about de re modality. I argue that this is not a coherent combination of views: one must go fully conventionalist, or fully realist. The central argument displays the difficulty for the modal conventionalist/object realist in specifying the object that satisfies de re modal predicates. I argue that if (...) this is a mind-independent object, contradictions arise when we consider the possibility or actuality of non-equivalent conventions both applying to 'the same object'. (shrink)

Mereological nihilism is the view that no objects have proper parts. Despite how counter‐intuitive it is, it is taken quite seriously, largely because it solves a number of puzzles in the metaphysics of material objects – or so its proponents claim. In this article, I show that for every puzzle that mereological nihilism solves, there is a similar puzzle that (a) it doesn’t solve, and (b) every other solution to the original puzzle does solve. Since the solutions (...) to the new puzzles apply just as well to the old puzzles, the old puzzles provide no motivation to be a mereological nihilist. (shrink)

It is commonly believed that there are, in the world, large numbers of objects which occupy three-dimensional space. It is also commonly believed that at least a large part of people's experience is of the surfaces of these material objects. Nevertheless, arguments have been adduced in favour of the view that we are never aware of such surfaces but only of distinct items called ‘sense-data’. It has also been suggested that if we couple the view that experience (...) is limited to sense-data with an empiricist thesis to the effect that knowledge is limited by experience then we are forced to the conclusion that we cannot have any knowledge of material objects. There have been many attempts to reconcile the sense-data thesis with common beliefs about material objects. Among them have been representative realism and phenomenalism. However, a view which may have found favour recently is the Quinean one that ‘the myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience’. 1.

Mainstream analytic metaphysics is a priori metaphysics. It is hemmed in by basic assumptions that rest on no more than a priori intuitions. Jaegwon Kim's arguments about causation are a paradigm example of sophisticated arguments with little or no justification from the world as we know it. And Peter van Inwagen's arguments about material objects are motivated by a question that, I think, has no nontrivial answer: Under what conditions do some x's compose an object y? (...) The trivial answers are "always" and "never." Any other answer, including van Inwagen's, seems to me to be arbitrary—and again based on a priori intuitions. To cite two more examples that I find egregious: The assumption that there is a metaphysically important distinction between what is mind-independent and what is not, and the assumption that there is a metaphysically important distinction, among things that are real, between what is fundamental and what is not. A priori intuitions, especially when not shared by philosophers outside a small circle of specially trained people, seem a weak reed on which to hang metaphysical systems. (shrink)

Introduces several of the concepts and assumptions that will occupy center stage in the book's main argument. In particular, introduces the notion of a research programme, and provides characterizations of realism about material objects and its rival, constructivism. Also defends the conclusion that it is impossible to adopt a research programme on the basis of evidence. This constitutes the author's argument for the conditional claim that if naturalism is a research programme, its status as orthodoxy is (...) without rational foundation. Introduces the central thesis of the book – that naturalists are committed to rejecting realism about material objects, materialism, and perhaps realism about other minds – and goes on to provide a brief outline of the remaining chapters. (shrink)

In an earlier chapter, the author argues that naturalists can justifiably accept realism about material objects only if the methods of science justify belief in intrinsic modal properties. One suggestion as to how they might do this is as follows: beliefs attributing intrinsic modal properties to material objects are justified because their truth provides a good explanation for the existence of proper functions in nature. This examines this suggestion and argues that, except in the (...) case of objects that are the products of design, proper functions are not empirically detectable. (shrink)

Begins the second part of the book, in which the author argues that commitment to the naturalistic research programme precludes one from accepting realism about material objects and materialism. The argument turns on the prospects that naturalists have for solving what the author calls the Discovery Problem. Roughly, the Discovery Problem is just the fact that intrinsic modal properties seem not to be discoverable by the methods of science. Describes this problem in Ch. 4, and argues (...) that if there is good reason to think that the problem cannot be solved, then naturalists cannot be justified in accepting realism about material objects. (shrink)

Argues that, having been forced to give up realism about material objects, naturalists are committed to accepting constructivism, the view that the modal properties of material objects are mind‐dependent. Also argues that, in accepting constructivism, naturalists must give up materialism. Finally, shows that, once materialism has been given up, standard arguments against mind‐body dualism turn their teeth against realism about other minds.

Objectivity has a history, and it is full of surprises. In Objectivity, Lorraine Daston and Peter Galison chart the emergence of objectivity in the mid-nineteenth-century sciences--and show how the concept differs from its alternatives, truth-to-nature and trained judgment. This is a story of lofty epistemic ideals fused with workaday practices in the making of scientific images. From the eighteenth through the early twenty-first centuries, the images that reveal the deepest commitments of the empirical sciences--from anatomy to crystallography--are those featured in (...) scientific atlases, the compendia that teach practitioners what is worth looking at and how to look at it. Galison and Daston use atlas images to uncover a hidden history of scientific objectivity and its rivals. Whether an atlas maker idealizes an image to capture the essentials in the name of truth-to-nature or refuses to erase even the most incidental detail in the name of objectivity or highlights patterns in the name of trained judgment is a decision enforced by an ethos as well as by an epistemology. As Daston and Galison argue, atlases shape the subjects as well as the objects of science. To pursue objectivity--or truth-to-nature or trained judgment--is simultaneously to cultivate a distinctive scientific self wherein knowing and knower converge. Moreover, the very point at which they visibly converge is in the very act of seeing not as a separate individual but as a member of a particular scientific community. Embedded in the atlas image, therefore, are the traces of consequential choices about knowledge, persona, and collective sight. Objectivity is a book addressed to anyone interested in the elusive and crucial notion of objectivity-- and in what it means to peer into the world scientifically. Lorraine Daston is Director at the Max Planck Institute for the History of Science in Berlin, Germany. She is the coauthor of Wonders and the Order of Nature, 1150-1750 and the editor of Things That Talk: Object Lessons from Art and Science. Peter Galison is Pellegrino University Professor of the History of Science and of Physics at Harvard University.

Direct Realism often emerges as a solution to a certain type of problem. Hume and, especially, Berkeley, wielding some of the most powerful arguments of 18th Century philosophy, forcefully attacked the notion that there could be good inferences from the occurrence of one’s sensations to the existence of external, mind-independent bodies. Given the success of these attacks, and also given the assumption, made by Berkeley and arguably by Hume as well, that our knowledge of and rational belief in the (...) existence of material objects would depend upon there being such good inferences, a problem arises: We cannot know of or rationally believe in the existence of material objects. Reid’s Direct Realism then emerges as the solution to this problem. Reid admits the success of Berkeley’s and Hume’s attacks against the possibility of successfully grounding our material world beliefs on inferences from our sensations,[1] but claims that our belief in the existence of material objects can be perfectly rationally acceptable, and can amount to knowledge, despite the lack of such inferences. Though he did not use the terminology, it seems to be Reid’s position – and it’s this position that I will be referring to as his “Direct Realism” here – that certain perceptual beliefs whose content is such that they imply the existence of material objects are properly basic: they are rationally held, and if true can amount to knowledge, without having to be based on any other beliefs, including, most notably, beliefs about one’s own sensory experiences.

My goal in this paper is to provide critical discussion of Michael Rea’s case for three of the controversial theses defended in his World Without Design (Oxford University Press, 2002): (1) that naturalism must be viewed as what he calls a “research program”; (2) that naturalism “cannot be adopted on the basis of evidence,” as he puts it; and (3) that naturalists cannot be justified in accepting realism about material objects.

In this paper I describe the place of naive realism in Russell’s changing accounts of perception. I argue ‎for the following conclusions: (1) The early period, 1898-1910: I am inclined to think that the naïve ‎realism that Russell embraced so enthusiastically early on may not have been intended as a naïve ‎realism about perception, but as a metaphysical or semantical thesis. (2) The Problems of Philosophy ‎‎(1912): Russell abandons naïve realism (if, in fact, he ever (...) held it) and presents a sense-datum version ‎of representative realism. (3) “On Matter” (1912): here we see Russell’s best attempt to defend ‎something very close to the standard doctrine of naïve realism. The objects of perception—the ‎‎“everyday material objects such as caterpillars and Cadillacs”—have, of course, undergone severe ‎reconstruction. But the resulting picture does capture the spirit of the doctrine. (4) The period from ‎‎1914 to 1927: though Russell’s thinking about perception underwent some significant changes during ‎this period—the sense datum theory is replaced by neutral monism—I try to show that the ‎distinction between the matter of physics and the thing of common sense is a constant feature of ‎Russell’s changing views. And I suggest that our perceptual relation the thing of common ‎sense (as logically reconstructed by Russell) can usefully be viewed as a limited sort of naïve realism. ‎‎(5) The period after 1927: the thing of common sense no longer features in Russell’s account of our ‎perceptual access to the world. The things we perceive are percepts, located in our private spaces. The ‎only material objects of which these percepts are parts are our brains. All other material objects are ‎beyond our perceptual reach and are accessible only via inference. This is the end of anything ‎resembling the traditional view of naïve realism in Russell’s account of perception. ‎. (shrink)

Two views about the objects of history have traditionally been opposed: the realist, which holds that history is about past actuality: and the constructionist, which holds that history cannot be about a past actuality but rather it is about what survives the materials and procedures of historical research. I shall suggest that both of these views may well agree that, as regards the practice of historical inquiry, an historian is constrained by what survives the materials (...) and procedures of historical research. And this agreement provides the basis for raising questions about the very distinction between the epistemology and the ontology of history. (shrink)

A critical study of Rea's book, focusing on his case for three theses: that naturalism must be viewed as a ‘research programme’; that naturalism ‘cannot be adopted on the basis of evidence’; and that naturalists cannot be justified in accepting realism about material objects.

One of the most important and perennially debated philosophical questions is whether we can have knowledge of the external world. Butchvarov here considers whether and how skepticism with regard to such knowledge can be refuted or at least answered. He argues that only a direct realist view of perception has any hope of providing a compelling response to the skeptic and introduces the radical innovation that the direct object of perceptual, and even dreaming and hallucinatory, experience is always a (...) class='Hi'>material object, but not necessarily one that actually exists. This leads him to a metaphysics in which reality is ultimately constructed by human decisions out of objects that are ontologically more basic but which cannot be said in themselves to be either real or unreal.

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, (...) in particular, whether colors are any of the properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

I argue that one’s views about which “metaphysical laws” obtain—including laws about what is identical with what, about what is reducible to what, and about what grounds what—can be used to deflect or neutralize the threat posed by a debunking explanation.

Then, after defending the proposed strategy from the charge of question-begging, I close by showing how the proposed (...) strategy can be used by certain moral realists to resist the evolutionary debunking arguments.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Kant’s Transcendental Proof of RealismBrandon C. LookKenneth R. Westphal. Kant’s Transcendental Proof of Realism. New York: Cambridge University Press, 2004. Pp. x + 299. Cloth, $80.00.Westphal's book is a rich and exciting contribution to the field of Kant studies. Its claims run counter to much contemporary discussion of Kant's theoretical philosophy and indeed challenge some of Kant's fundamental doctrines, but the arguments are very compelling and therefore (...) likely to force us to rethink both the Critique of Pure Reason [CPR] and Kant's relevance to contemporary epistemology.The central point of this work is that, if we follow Kant's injunction to engage in reflection on our cognitive capacities, then we will be led not to Kantian transcendental idealism but to an unqualified realism about objects and events in space and time. The book's first three chapters are devoted to analyzing Kant's methodology and the much-overlooked idea of transcendental affinity. Westphal focuses on the Kantian duty of engaging in "transcendental reflection," which is "the action through which I make the comparison of representations in general with the cognitive power in which they are situated, and through which I distinguish whether they are to be compared with one another as belonging to pure understanding or to sensible intuition" (CPR, A 261/B 317). And he adds to this the more general methodological obligation of "epistemic reflection," or the duty to determine precisely our cognitive capacities and incapacities. If, then, we reflect on our representations, their origins in sensibility and the understanding, and on our powers to know things of ourselves and the world in general, then certain puzzles arise—puzzles that were confronted by Kant (and Hume and Hegel) but that have not received the attention they have deserved. Chief among these puzzles is our ability to identify single objects and events and track them in space through time. But, as Westphal is keen to point out, identifying any particular over time requires that we be able to re-identify that particular. Now, while this puzzle is addressed by Kant in the Transcendental Deduction and Analogies of Experience, it is important to see that there is a material condition necessary for the possibility of self-conscious experience of the world that is not fleshed out in great detail by Kant and seems to be completely overlooked in the literature on Kant, namely, "the presupposition of diversity in nature" and the homogeneity of its objects among themselves (CPR, A 657/B 685). In other words, the fact that we are able to associate our various sensations with each other at all (and thereby identify and re-identify objects) is due to their "transcendental affinity." And it is Westphal's contention that "on Kant's own principles, the transcendental affinity of the manifold of sensory intuition can only be reconstructed, but not constructed, by intellectual syntheses of the understanding" (91). Therefore, pace Kant, who held that only his transcendental idealism could explain the possibility of experience, Westphal argues that transcendental idealism runs afoul of many of Kant's own arguments and observations in the Transcendental Aesthetic and Transcendental Analytic and, more important, that transcendental affinity provides grounds for "realism sans phrase" (the author's phrase) about objects and events in space and time, and for the view that our mental states are determined by external objects. As Westphal puts it in his conclusion: "Kant's analysis of transcendental affinity is in fact a transcendental argument for mental content externalism" (266). [End Page 665]The second part of Westphal's argument revolves around a detailed examination of Kant's theses about transeunt causality and the nature of matter as expressed not only in the Critique of Pure Reason, but also in the Metaphysical Foundations of Natural Science and the Opus postumum. Roughly the problem is this: in order to have an adequately grounded metaphysics of nature, Kant needs not only the results of the Analogies of Experience, the transcendental causal thesis that every event has a cause, but also the metaphysical causal thesis that every physical event has an external physical cause. But, according to Westphal, in the Metaphysical Foundations... (shrink)

This paper explicates and argues for the thesis that individual rational judgment, of the kind required for rational justification in non-formal, substantive domains – i.e. in empirical knowledge or in morals (both ethics and justice) – is in fundamental part socially and historically based, although these social and historical aspects of rational justification are consistent with realism about the objects of empirical knowledge and with strict objectivity about basic moral principles. The central thesis is that, to (...) judge fully rationally that one judges – in ways which provide rational justification of one’s judgment about any substantive matter – requires recognising one’s inherent fallibility and consequently also recognising our mutual interdependence for assessing our own and each others’ judgments and their justification. This explication provides a pragmatic account of rational justification in substantive domains which puts paid to the traditional distinction, still influential today, between ‘rational’ and ‘historical’ knowledge. (Note: This paper is a counterpart to Westphal 2011b; each paper contains substantial material not included in the other.). (shrink)

The concept of “magic realism” raises many problems, both theoretical and historical. I first encountered it in the context of American painting in the mid-1950s; at about the same time, Angle Flores published an influential article in which the term was applied to the work of Borges;1 but Alejo Carpentier’s conception of the real maravilloso at once seemed to offer a related or alternative conception, while his own work and that of Miguel Angel Asturias seemed to demand an (...) enlargement of its application.2 Finally, with the novels of Gabriel García Márquez in the 1960s, a whole new realm of magic realism opened up whose exact relations to preceding theory and novelistic practice remained undetermined. These conceptual problems emerge most clearly when one juxtaposes the notion of magic realism with competing or overlapping terms. In the beginning, for instance, it was not clear how it was to be distinguished from that vaster category generally simply called fantastic literature; at this point, what is presumably at issue is a certain type of narrative or representation to be distinguished from realism. Carpentier, however, explicitly staged his version as a more authentic Latin American realization of what in the more reified European context took the form of surrealism: his emphasis would seem to have been on a certain poetic transfiguration of the object world itself—not so much a fantastic narrative, then, as a metamorphosis in perception and in things perceived . In García Márquez, finally, these two tendencies seemed to achieve a new kind of synthesis—a transfigured object world in which fantastic events are also narrated. But at this point, the focus of the conception of magic realism would appear to have shifted to what must be called an anthropological perspective: magic realism now comes to be understood as a kind of narrative raw material derived essentially from peasant society, drawing in sophisticated ways on the world of village or even tribal myth. Recent debates, meanwhile, have complicated all this with yet a different kind of issue: namely, the problem of the political or mystificatory value, respectively, of such texts, many of which we owe to overtly left-wing revolutionary writers .3 In spite of these terminological complexities—which might be grounds for abandoning the concept altogether—it retains a strange seductiveness which I will try to explore further, adding to the confusion with reference points drawn from the work of Jacques Lacan and from Freud’s notion of the “uncanny,” and compounding it by an argument that magic realism is to be grasped as a possible alternative to the narrative logic of contemporary postmodernism.4 1.

Mathematics is one of the many domains where the adoption of a form of realism has traditionally been challenged. Behaviorism and phenomenalism, opposed to realism about, respectively, mental entities and the existence of material objects, are other well‐known examples. The realism debate, as initiated by Dummett's challenge, appears to have run its course, at least on its original terms, and difficulties have been raised with respect to both antirealist and anti‐antirealist readings of Wittgenstein within (...) that debate. Realism about meaning did not remain unchallenged, however, as successor debates took its place, surrounding Robert Brandom's “inferentialism” or Price's generalized form of quasi‐realism, called “pragmatism”. Brandom also espouses “non‐representationalism” and predictably made use of Wittgenstein, with a reading akin to Kripke's of the rule‐following argument. He was criticized by McDowell largely for failing to account for Wittgenstein's quietism. (shrink)

It is uncontroversial that artifacts like statues and tables are mind-dependent. What is controversial is whether and how this mind-dependence has implications for the ontology of artifacts. I argue the mind-dependence of artifacts entails that there are no artifacts or artifact joints in the extra-mental world. In support of this claim, I argue that artifacts and artifact joints lack any extra-mental grounding, and so ought not to have a spot in a realist ontology. I conclude that the most plausible story (...) about artifacts is that they are in minds of suitably intelligent creatures, and not the extra-mental world. Artifacts and their joints are merely mental projections onto a world of ‘indifferent materials’. With this established, I show how many cases of object coincidence, the view that more than one material object can be located in the same exact region of space-time, cannot occur. (shrink)

Contemporary philosophers of mathematics are deadlocked between two alternative ontologies for numbers: Platonism and nominalism. According to contemporary mathematical Platonism, numbers are real abstract objects, i.e. particulars which are nonetheless “wholly nonphysical, nonmental, nonspatial, nontemporal, and noncausal.” While this view does justice to intuitions about numbers and mathematical semantics, it leaves unclear how we could ever learn anything by mathematical inquiry. Mathematical nominalism, by contrast, holds that numbers do not exist extra-mentally, which raises difficulties about how mathematical (...) statements could be true or false. Both theories, moreover, leave inexplicable how mathematics could have such a close relationship with natural science, since neither abstract nor mental objects can influence concrete physical objects. The Thomist understanding of quantity as an accident inhering in concrete substances breaks this deadlock by granting numbers a foundation in extra-mental reality which explains why numeric expressions are relevant in natural science and how we come to know the truth or falsity of mathematical statements. Further, this kind of moderate realism captures the semantic advantages of the Platonists and the ontological parsimony of the nominalists (since for Thomists quantity is not a separate, free-standing ontological addition). Despite these advantages, the Thomistic understanding of number has been out of favor since the work of Cantor, who argued that actual infinities (regarded by Aristotelians as impossible) are required for modern developments in mathematics. This paper frees philosophers of mathematics to embrace the advantages of Thomistic realism by showing that Cantor’s understanding of actual and potential infinity is not the same as Aquinas’s, and that potential infinities (in Aquinas and Aristotle’s sense) can do all the work Cantor claims for actual infinities in modern mathematics.

This paper is a review of 'Aquinas and the Ship of Theseus: Solving Puzzles about Material Objects' by Christopher M. Brown.

Are fictional characters such as Sherlock Holmes real? What can fiction tell us about the nature of truth and reality? In this excellent introduction to the problem of fictionalism R. M. Sainsbury covers the following key topics: what is fiction? realism about fictional objects, including the arguments that fictional objects are real but non-existent; real but non-factual; real but non-concrete the relationship between fictional characters and non-actual worlds fictional entities as abstract artefacts fiction and intentionality (...) and the problem of irrealism fictionalism about possible worlds moral fictionalism. R. M. Sainsbury makes extensive use of examples from fiction, such as Sherlock Holmes, Anna Karenina and Madame Bovary and examines the work of philosophers who have made significant contributions to the topic, including Meinong, David Lewis, and Bas Van Fraassen. Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making _Fiction and Fictionalism_ ideal for those coming to the issue for the first time.

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property possession is not analysed as bundle-membership, as in traditional bundle theories, since accidental properties are not included in the object’s bundle. We have a different story to tell about accidental property possession. This move reaps many benefits. (...) Essential bundle theory delivers a simple theory of the essential properties of material objects; an explanation of how object coincidence can arise; an actual-world ground for modal differences between coincident objects; a simple story about intrinsic properties; and a plausible account of certain ubiquitous cases of causal overdetermination.

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

Literary Theory and the Claims of History: Postmodernism, Objectivity, Multicultural Politics. Ithaca: Cornell UP, 1997.Martha C. Nussbaum. Cultivating Humanity: A Classical Defense of Reform in Liberal Education. Cambridge: Harvard UP, 1997.It is arguably a peculiar fact that a book announcing itself as a defense of objectivity and realism would begin by assuring readers of the (...) political efficacy of its theories. After all, the critique of objectivity and realism within progressive cultural criticism of the past several decades has taken for granted that claims to objectivity and realism are suspicious in part because of their pretense to value-neutrality. But Satya P. Mohanty’s ambitious and wide-ranging Literary Theory and the Claims of History joins with other recent attempts to lay claim to a refurbished realism that not only overcomes variously construed limitations of postmodernism but fully answers to the charges leveled against “traditional” objectivity or “naïve” realism [see Alcoff; Livingston]. Such a project can in part be analyzed against a broader critique of postmodernism and poststructuralism advanced through reconsideration of Enlightenment ideals, including, most prominently, the ideals of universalism and its less abstract cousin, cosmopolitanism [see Anderson]. The reconstructions of both universalism and realism have claimed a greater intellectual integrity and coherence than the forms of postmodernism that they challenge and a more promising ethico-political vision, one that more convincingly acknowledges the place and claims of marginalized others. These reconstructive projects thus fundamentally challenge the familiar postmodernist idea that claims to universalism or objectivity themselves enact forms of privilege or exclusion that inherently disable any properly egalitarian or nonviolent relation to others.Mohanty would appear to combine the universalist and realist ambitions, insofar as he asserts a moral position based on Kantian notions of autonomy and dignity at the same time that, in epistemological terms, he elaborates a “postpositivist realist alternative.” Maintaining that the critique of objectivity within postmodernism is propped up by an outdated understanding of scientific method and theory, he argues that the more sophisticated theories within current philosophy of science elaborate epistemological models that are fully compatible with a generalized hermeneutical method, precisely because they acknowledge both the theory-laden nature of all inquiry and the larger social and historical contexts of knowledge and experience. Before elaborating this realist alternative, however, Mohanty situates his project by forwarding a number of critiques of “constructivist postmodernism,” critiques that enable us to better gauge the motivations behind his work. Foregrounded at the start are what Mohanty sees as the [End Page 3] harmful political and ethical consequences of relativism, skepticism, and constructivism. According to Mohanty, while the claims for diversity and difference in the 1960s “had a political edge,” at this historical moment they are used primarily for conservative ends, via a state-sponsored bland multiculturalism that diverts attention from the blunt material issues of race politics [17]. In broader ethico-political terms, moreover, relativist arguments that display skepticism toward the possibilities for rational exchange between variously construed collectivities and cultures lead not to a proper respect for the other but rather to indifference. As Mohanty puts it, to deny the possibility of “general criteria” for “interpretive validity” is “to assert that all spaces are equivalent, that they have equal value, that since the lowest common principle of evaluation is all that I can invoke, I cannot—and consequently need not—think about how your space impinges on mine or how my history is defined together with yours. If that is the case, I may have started by declaring a pious political wish, but I end by denying that I need to take you seriously” [131; Mohanty’s emphasis].Beyond these harmful consequences, however, lies a more fundamental problem. In its monolithic assault on Western Reason and the unified subject of humanism, constructivist postmodernism has deprived itself of any coherent account of human agency and rationality. Without a philosophical anthropology establishing the “capacities, tasks, and limits that might make up a specifically human existence,” Mohanty argues, it becomes impossible to account properly for cultural practices and historical agency, for the self-understanding of cultures and the historical transformations they enact [138...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Kant’s Transcendental Proof of RealismBrandon C. LookKenneth R. Westphal. Kant’s Transcendental Proof of Realism. New York: Cambridge University Press, 2004. Pp. x + 299. Cloth, $80.00.Westphal's book is a rich and exciting contribution to the field of Kant studies. Its claims run counter to much contemporary discussion of Kant's theoretical philosophy and indeed challenge some of Kant's fundamental doctrines, but the arguments are very compelling and therefore (...) likely to force us to rethink both the Critique of Pure Reason [CPR] and Kant's relevance to contemporary epistemology.The central point of this work is that, if we follow Kant's injunction to engage in reflection on our cognitive capacities, then we will be led not to Kantian transcendental idealism but to an unqualified realism about objects and events in space and time. The book's first three chapters are devoted to analyzing Kant's methodology and the much-overlooked idea of transcendental affinity. Westphal focuses on the Kantian duty of engaging in "transcendental reflection," which is "the action through which I make the comparison of representations in general with the cognitive power in which they are situated, and through which I distinguish whether they are to be compared with one another as belonging to pure understanding or to sensible intuition" (CPR, A 261/B 317). And he adds to this the more general methodological obligation of "epistemic reflection," or the duty to determine precisely our cognitive capacities and incapacities. If, then, we reflect on our representations, their origins in sensibility and the understanding, and on our powers to know things of ourselves and the world in general, then certain puzzles arise—puzzles that were confronted by Kant (and Hume and Hegel) but that have not received the attention they have deserved. Chief among these puzzles is our ability to identify single objects and events and track them in space through time. But, as Westphal is keen to point out, identifying any particular over time requires that we be able to re-identify that particular. Now, while this puzzle is addressed by Kant in the Transcendental Deduction and Analogies of Experience, it is important to see that there is a material condition necessary for the possibility of self-conscious experience of the world that is not fleshed out in great detail by Kant and seems to be completely overlooked in the literature on Kant, namely, "the presupposition of diversity in nature" and the homogeneity of its objects among themselves (CPR, A 657/B 685). In other words, the fact that we are able to associate our various sensations with each other at all (and thereby identify and re-identify objects) is due to their "transcendental affinity." And it is Westphal's contention that "on Kant's own principles, the transcendental affinity of the manifold of sensory intuition can only be reconstructed, but not constructed, by intellectual syntheses of the understanding" (91). Therefore, pace Kant, who held that only his transcendental idealism could explain the possibility of experience, Westphal argues that transcendental idealism runs afoul of many of Kant's own arguments and observations in the Transcendental Aesthetic and Transcendental Analytic and, more important, that transcendental affinity provides grounds for "realism sans phrase" (the author's phrase) about objects and events in space and time, and for the view that our mental states are determined by external objects. As Westphal puts it in his conclusion: "Kant's analysis of transcendental affinity is in fact a transcendental argument for mental content externalism" (266). [End Page 665]The second part of Westphal's argument revolves around a detailed examination of Kant's theses about transeunt causality and the nature of matter as expressed not only in the Critique of Pure Reason, but also in the Metaphysical Foundations of Natural Science and the Opus postumum. Roughly the problem is this: in order to have an adequately grounded metaphysics of nature, Kant needs not only the results of the Analogies of Experience, the transcendental causal thesis that every event has a cause, but also the metaphysical causal thesis that every physical event has an external physical cause. But, according to Westphal, in the Metaphysical Foundations... (shrink)

The problem of other minds has widely been considered as a special problem within the debate about scepticism. If one cannot be sure that there is a world existing independently of one's mind, how can we be sure that there are minds - minds which we cannot even experience the way we experience material objects? This book shows, through a detailed examination of David Hume's A Treatise of Human Nature, that these concerns are unfounded. By focusing on (...) Hume's discussion of sympathy - the ability to connect with the mental contents of other persons - Anik Waldow demonstrates that belief in other minds can be justified by the same means as belief in material objects. The book thus not only provides the first large-scale treatment of the function of the belief in other minds within the Treatise, thereby adding a new dimension to Hume's realism, but also serves as an invaluable guide to the complexity of the problem of other minds and its various responses in contemporary debate.

A successful vision system must solve the problem of deriving geometrical information about three-dimensional objects from two-dimensional photometric input. The human visual system solves this problem with remarkable efficiency, and one challenge in vision research is to understand howneural representations of objects are formed and what visual information is used to form these representations. Ideal observer analysis has demonstrated the advantages of studying vision from the perspective of explicit generative models and a specified visual task, which divides (...) the causes of image variations into the separate categories of signal and noise. Classification image techniques estimate the visual information used in a task from the properties of “noise” images that interact most strongly with the task. Both ideal observer analysis and classification image techniques rely on the assumption of a generative model. We show here how the ability of the classification image approach to understand how an observer uses visual information can be improved by matching the type and dimensionality of the model to that of the neural representation or internal template being studied. Because image variation in real world object tasks can arise from both geometrical shape and photometric (illumination or material) changes, a realistic image generation process should model geometry as well as intensity. A simple example is used to demonstrate what we refer to as a “classification object” approach to studying three-dimensional object representations. (shrink)

This paper is a discussion of Gödel's arguments for a Platonistic conception of mathematical objects. I review the arguments that Gödel offers in different papers, and compare them to unpublished material (from Gödel's Nachlass). My claim is that Gödel's later arguments simply intend to establish that mathematical knowledge cannot be accounted for by a reflexive analysis of our mental acts. In other words, there is at the basis of mathematics some data whose constitution cannot be explained by introspective (...) analysis. This does not mean that mathematics is independent of the human mind, but only that it is independent of our ?conscious acts and decisions?, to use Gödel's own words. Mathematical objects may then have been created by the human mind, but if so, the process of creation cannot be completely analysed and re-enacted. Such a thesis is weaker than some of the statements that Gödel made about his conceptual realism. However, there is evidence that Gödel seriously considered this weak thesis, or a position depending only on this weak thesis. He also criticized Husserl's Phenomenology from this point of view.

l. THE GENERAL PROBLEM OF EPISTEMOLOGY There is a philosophical issue that surely precedes all other possible questions. It concerns the very possibility of our thinking about some thing to some purpose. Short of this no philosophy, theory or research would be possible. But it is not immediately clear that we are assured that what purports to be effective thought, and cognition is such in reality. What guarantee is there for instance that when one is under the impression that (...) one is thinking that "the cat is on the mat" it is in fact the case that one is thinking this? One could not be thinking at all, only having a misleading mystic experience. And then even if one was thinking, one might not be really thinking of the cat being on the mat, but only that one wishes there was a cat, and wonders whether if there was it would be on the mat, and yet the subjective impression was that one was thinking: "The cat is on the mat". Then one might in some way try to think 'the cat is on the mat. ' yet be mistaken in that there aren't any material objects at all, and all one does is to inventory god's perceptions. And so on, and so on! These are of course the kind of problem that the layman habitually views with disdainful alarm. (shrink)

Among scientific realists and anti-realists, there is a well-known, perennial dispute about the reality and knowability of unobservable objects. This dispute is also present among structural realists, who all agree that science gives us genuine knowledge of structure at the unobservable level (however that structure may be understood). Ontic structural realists reduce or eliminate the ontological role of objects, while epistemic structural realists argue that objects do or might exist but are unknowable. In part because ontic (...) structural realism has some evidence from quantum mechanics and the consequent underdetermination of the metaphysics of objects in its favor, the majority of contemporary structural realists adopt that view. In contrast, I argue that epistemic structural realism is a highly compelling view, particularly in the form that remains agnostic about unobservable objects. This view can remain consistent with the empirical data from quantum mechanics, can give a satisfactory account of the metaphysics of structure, and can distinguish itself from other extant versions of realism. I provide two arguments in favor of agnosticism about objects, the first of which argues that suspending belief is consistent with the impetus of naturalized metaphysics, and the second of which argues that agnosticism about objects is a rational response to reflection on the limits and aims of science. Thus, I show that agnostic epistemic structural realism is a defensible and compelling view in the philosophy of science that demands more attention in the literature. (shrink)
