The success of a scientific theory T is not an all-or-nothing matter; nor is a theory something one can usually accept or reject in toto (i.e. one may take T as being "approximately true", or take as true just certain "parts" of it, without necessarily affirming every posit and claim specific to T as being either completely right or completely wrong). This, however, raises questions about precisely which parts of T deserve to be taken as approximately true. on the basis (...) of its success. A line of thinkers, particularly Kitcher, Leplin and Psillos, variously look for parts of a theory they can claim to have been "essentially" implicated in its distinctivesuccess, which they regard as primary candidates for realist truth ascription. But, how is one to determine which parts of any theory are "central" or "peripheral", "essential" or "idle" in the required sense? Attempts at spelling out relevant synchronic links between successful predictions and correct partial theorizing increasingly look like a misguided effort. As an alternative, this paper proposes a weaker, but arguably powerful enough, version of the realist relation between success and truth. Focusing on a pivotal case study in recent debates between realists and anti-realists (the conceptual changes undergone by theories oflight in the 19th century), a promising link between success and partial theoretical representation is located in the expansion and stabilization of approximately correct partial theoretical models of the theory's intended domain. The realist link is then formulated accordingly. In the resulting approach (a) predictive success is preserved as a marker of cumulative theoretical gain, but (b) specification of the latter is a diachronic rather than synchronic matter (i.e. gains become clear only after generations of theory change; specification of the particular loci of theoretical gain in connection with a given line of predictive success is not assumed to be generally possible at the time of the success in question). The truth ascriptions that get licensed are partial-of a piece-meal and retrospective sort, focused on methodologically specifiable theoretical subplots from past science. (shrink)

Realism is often characterized by the claim that sentences are true or false in virtue of their ‘fit’ with reality. However, philosophers motivated by the deflationary view of truth argue that the formulation and defense of realism does not require a substantial conception of truth. The role of truth in stating and defendingrealism can be accounted for in terms of its being a device for expressing generalizations. I sketch the outline of an argument against this position. I begin (...) with the deflationary view of truth and its relevance for realism. I argue that the deflationary view of truth does not show that truth is only being used as a device for expressing generalizations. I then argue that a robust conception of truth is needed to make sense of the objectivity dimension of realism and for the realist explanation of how language contributes to our success in achieving our goals.

Anti-realists about the past claim that no one has yet manifested a knowledge of the truth of tensed instances of the realist schema '‡,' instances such as '‡. It is true that we cannot decide specific instances of the realist schema and that, consequently, neither our understanding of these instances, nor our knowledge of their truth may be constituted by the recognitional and executive capacities which, according to Michael Dummett's antirealism, constitute grasp of meaning. Although we cannot decide these issues, (...) we can meet Dummett's anti-realist's manifestability challenge by arguing for them from contingency. While no recognitional and decisional skills may constitute our knowledge that their truth-conditions are satisfied, we can, without begging the question, derive that knowledge from our folk and scientific theories of the workings of nature. The evidence we have in favor of the fact that evidential relations between us and past facts are naturally contingent allows us to infer tensed instances of the fundamental realist modal claim. The joint possibility of truth and undecideability pro tempora is a natural possibility and, thereby, a logical and metaphysical possibility. (shrink)

The development of string theory shows an unusual situation within the development of knowledge theory. Science achieves progress in understanding nature without direct empirical confirmation. Definitely, “an altered conception of scientific progress emerges” (R. Dawid). In our opinion, the only possibility to understand the new situation is to adopt some kind of naturalized epistemology. Naturalization viewed as declining of the a-prioriticity of philosophical knowledge, first, and reintroducing of psychology, second (P. Kitcher), gives many naturalized approaches in the realism debate (...) field. Is it possible to extend realism heritage into the ironic science like string theory? Yes, but of course we should be bothered by the semantics issue in such a case.

We think that Devitt’s interpretation of the semantics role allows to extend realism even into the ironic science. (shrink)

Kant's account of subjectivity is ambiguous: there is an implicit critique of Descartes in Kaaat, but this is in conflict with more Cartesian aspects of his approach to subjectivity. Fichte develops the critical elements of Kant and turns them against Kant's residual Cartesianism. Fichte, in the various versions of the Wissenschaftslehre, is the first to be aware of the limitations of the reflective model of consciousness. In those texts he presents his alternative model for subjectivity by trying to conceive of (...) selfconsciousness such that the self-relation makes no separation between thinker and thought. While Fichte 's insight into the limitations of the reflective model of consciousness is generally accepted, his own account of the character of the immediate self-relation, which he presents as the alternative to the reflective model, was never satisfactorily resolved. The exposition of Fichte will examine his theory of subjectivity in relation to the central notion of striving; it will be argued that the notion of a striving subject tries to reconcile the dichotomy of idealism and realism.

I argue that if we distinguish between ontological realism and semantic realism, then we no longer have to choose between platonism and formalism. If we take category theory as the language of mathematics, then a linguistic analysis of the content and structure of what we say in and about mathematical theories allows us to justify the inclusion of mathematical concepts and theories as legitimate objects of philosophical study. Insofar as this analysis relies on a distinction between ontological and (...) semantic realism, it relies also on an implicit distinction between mathematics as a descriptive science and mathematics as a descriptive discourse. It is this latter distinction which gives rise to the tension between the mathematician qua philosopher. In conclusion, I argue that the tensions between formalism and platonism, indeed between mathematician and philosopher, arise because of an assumption that there is an analogy between mathematical talk and talk in the physical sciences.

In his later writings, Wittgenstein is generally taken as committed to anti-realism. In this paper, I argue that this is mistaken. Although he is committed to ontic anti-realism, this does not preclude his acceptance of epistemic realism. I argue that the possibility of using practices to fix meanings and to provide aframework for conceptual differentiation of our experiences rests upon a version of realism, which I call "praxial realism", which does not presuppose anything like a (...) Kantian noumenal world. (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.

It is shown that the Nominalism of much of Modern Logic is what has given rise to many of its problems, especially The Liar Paradox. Shifting to a Realist Logic, in which ‘that’-clauses have a central place, overcomes these problems. The move involved, from the study of mentioned sentences to the employment of ‘that’-clauses, reveals the indexicality of referring phrases, and it is that which enables an escape from The Liar. But also it is shown that no parallel paradox is (...) obtainable with the propositions that ‘that’-clauses designate. Several theoretical issues, however, then need to be faced about what ‘that’-clauses designate, primarily what has been called the problem of ‘The Unity of the Proposition’. The term ‘proposition’, it turns out, is not always appropriate for what ‘that’-clauses designate, so a richer language is introduced to handle all cases. But the problem of the unity of what is designated arises in all cases, and is solved by noting a parallel with Russell’s treatment of individuals and descriptive phrases. (shrink)

We will investigate the implications of string theory for the scientific realism debate. Duality relations, which constitute a crucial conceptual characteristic of string theory, are of particular importance for the question of scientific realism in two ways. First, string dualities relate seemingly very different realizations of string theory to each other and establish their empirical equivalence. This feature of string theory works against an ontologically realist interpretation of the theory by turning pivotal characteristics of ontological objects into a (...) matter of choosing a specific formulation of the theory. Second, string dualities provide a basis for a final theory claim with respect to string theory. This final theory claim can provide a new conceptual framework for a realist interpretation of the theory. The final part of the talk will sketch the basic outlines of a realist conception that seems adequate in a string theoretical context. (shrink)

For the past thirty years postmodernism has been the major philosophical trend. Starting as a potentially emancipatory tool, though, it has virtually resolved into an acceptance of any kind of position, in the name of a very politically correct relativism. The aim of this essay is to provide an overview of New Realism in its opposition and reaction to Postmodernism, showing that it does not imply a return to a ‘traditional’ or ‘strong’ realism but that, on the contrary, (...) it involves a kind of ‘weak realism’: a blend between realism and constructivism. An analysis of the implications of both philosophical approaches in diverse fields will be offered, from epistemology, to politics, to ethics. Where postmodern epistemological claims will be proved to be quite easily confutable, its ethical implications will be faced more carefully. Ethical new realism will, therefore, be presented as particularly challenging, but also promising and important to the future of philosophy. (shrink)

This paper discusses Hacking’s experimental realism and suggests a concept of realization to the issue about realism. I first rephrase Hacking’s experimental realism by reconstructing them into two theses and three arguments. Then I consider that Resnik’s objection to Hacking’s experimental realism. According to my understanding of Hacking’s experimental realism, Resnik’s objection failed because of his position at theory realism. Nevertheless, I think that there are still two problems about the experimental aspect of the (...) experimental realism. They are the pessimistic induction of experimental science argument and the combination of apparatus argument. I attempt to give a new perspective on the realism issue by proposing a set of related concepts containing categorization, model, and realization. Last, I show that this conceptual scheme can give a better solution of the two problems and cast a new light on the realism issue. (shrink)

As a common saying goes “Hell is paved with good intentions”, though Kant would disagree. In real world we may be morally responsible for more than one’s intentions. Moral agents need to navigate between Scylla of “objective” and Charybdis of “subjective” theories of moral responsibility; the resultant theory shall be called a theory of realistic obligation. It takes into account both subjective intentions and objective results of moral action. Since human beings are both intentional entities and physical objects, neglect of (...) either objective or subjective factors leads to implausible consequences. In practical domains, such as business ethics, moral value needs to be assigned in part to our subjective intentions and in part to objective results of our actions. This allows for moral condemnation of inefficiency and balancing acts of efficiency versus deontic constraints. (shrink)

Objects which philosophers have traditionally categorized as abstract are standardly referred to by complex noun phrases of certain canonical forms, such as ‘the set of Fs’, ‘the number of Fs’, ‘the proposition that P’, and ‘the property of being F’. It is no accident that such noun phrases are well-suited to appear in ‘Fregean’ identity-criteria, or ‘abstraction’ principles, for which Frege’s criterion of identity for cardinal numbers provides the paradigm. Notoriously, such principlesare apt to create paradoxes, and the most intuitively (...) plausible ‘Fregean’ identity-criterion for properties is afflicted by this problem. In this case, it may be possible to overcome the difficulty by modifying the criterion in a way which requires an independent account of the existence-conditions of properties, but it appears that such a strategy demands acceptance of the doctrine of immanent realism—the view that a property exists only if it is exemplified by some object.

At this stage of evolution of our discipline, philosophy of science, there seems no single great theme that has attracted the attention of most practitioners in the field. Rather, scholarly works in the field are quite diffused. Traditional topics, such as reductionism and the unity of science, remain to be carefully examined from various perspectives. The debate over realism versus instrumentalism, although dismissed by some as uninteresting and unproductive, is still taken by many active scholars as vital in our (...) understanding of the nature of scientific theories and in our appraisal of scientific enterprise. Of course, the new spirit of our times has also shown itself, sometimes in the discussion of some major theses in the post-empiricist philosophy of science, such as incommensurability, underdetermination and constructivism, on the basis of detailed examination of scientific materials, other times in the shift of the attention from static aspects of science, such as theory justification and the nature of explanation, to more dynamic aspects, such as negotiations within a scientific community and its function and role in the development of science. Even more to the point in this regard is the great attention paid to the place science has occupied in modernity, the defect of modernist understanding of science and its possible remedy. Not surprisingly, this current state of affairs in our field has also manifested in the essays collected in this volume of contributions to the Twentieth World Congress of Philosophy. Thus, an inspection of these essays, although it will not provide us with a focus of the discipline, may give us some sense as to what is going on in the field. (shrink)

Many scientific realists think that the best reasons for scientific theories are abductive, i.e., must appeal to what is also called inference to the best explanation (IBE), while some anti-realists have argued that the use of abduction in defending realism is question-begging, circular, or incoherent. This paper studies the idea that abductive inference can be reformulated by taking its conclusion to concern the truthlikeness of a hypothetical theory on the basis of its success in explanation and prediction. The strength (...) of such arguments is measured by the estimated verisimilitude of its conclusion given the premises. It is argued that this formulation helps to make precise and justifies the "ultimate argument for scientific realism": the empirical success of scientific theories would be a miracle unless they are truthlike.

I discuss the so-called “problem of perception” in relation to the Argument from Illusion: Can we directly perceive the external world? According to Direct Realism, at least sometimes perception provides direct and immediate awareness of reality. But the Argument from Illusion threatens to undermine the possibility of genuine perception. In The Problem of Perception (2002), A. D. Smith proposes a novel defense of Direct Realism based on a careful study of perceptual phenomenology. According to his theory, the intentionality (...) of perception is explained in terms of three phenomenological features of perception: phenomenalthree-dimensional spatiality, movement, and the Anstoss. He argues that this account of perceptual intentionality can resist a central premise of the Argument from Illusion, i.e. the “sense-datum inference.” After presenting Smith’s theory, I argue that he fails to distinguish two independent tasks for the direct realist, and that he underestimates the threat of the so-called “sense-datum infection.” My contention is that even if Smith’s theory of perceptual intentionality is correct, Direct Realism has not been saved from the Argument from Illusion. To resist the Argument from Illusion, it is not enough to merely consider how to block the sense-datum inference. The direct realist must also find a way to undermine the sense-datum infection. If so, I suggest, Direct Realism cannot be defended by perceptual phenomenology alone. (shrink)

We are social animals in the sense that we spontaneously invent and continuously re-invent the social realm. But, not unlike other artifacts, once real, social relations, practices, institutions, etc., obey prior laws, some of which are moral laws. Hence, with regard to social reality, we ought to be ontological constructivists and moral realists. This is the view sketched here, taking as points of departure Searle's recent work on social ontology and May's on group morality. Moral and social selves are distinguished (...) to acknowledge that social reality is constructed but social morality is not. It is shown how and why moral law requiring respect for the dignity and well being of agents governs a social world comprising roles that are real only because of their occupants' social intentions.

Although scientific naturalistic philosophers have been concerned with the role of scientific psychology in illuminating problems in moral psychology, they have paid less attention to the contributions that it might make to issues of moral ontology. In this paper, I illustrate how findings in moral developmental psychology illuminate and advance the discussion of a long-standing issue in moral ontology, that of moral realism. To do this, I examine Gilbert Harman and Nicholas Sturgeon's discussion of that issue. I contend that (...) their explorations leave the issue unresolved. To break the stalemate, I appeal to empirical psychological findings about moral internalization-the process by which children acquire the capacity to act in terms of moral norms. I contend that these findings illuminate the issue, suggest a way to advance it, and tend to support a moral realist position. (shrink)

Feminist and post-colonial epistemologists, philosophers of science, and thinkers more generally may find themselves in a distinct form of difficult situation regarding their access to and authority over knowledge within the academic world. Because feminist and post-colonial approaches to knowledge require an acute awareness of relations of domination and the ways in which these pervade the social and epistemic world, it is often difficult to know how to proceed in making theory. These theorists are in particularly ripe positions to benefit (...) from what philosopher-physicist Karen Barad offers us. In this paper, I engage with parts of Karen Barad’s theory of agential realism, both critically and self-reflexively. I assert that allowing Barad’s theory to inform and structure our thinking and language makes knowers better able to meet certain requirements of epistemological responsibility, particularly with regard to the ways we make theory. Moreover, I attempt to assert this in a way that is mindful of how her theory speaks to and accounts for my doing so. (shrink)

My aim in this article is to analyze and to discuss what I think are the two most important approaches to a theory of truth from a non-realist standpoint: the proposal of Crispin Wright and the proposal enounced by Putnam in Reason, Truth and History. Wright argues for a minimalist theory of truth according to which truth has to be a metaphysically neutral notion and admits several possible models. One of these possible models is Putnam's notion of "rational acceptability under (...) ideal epistemic circumstances"; the other one is Wright's own proposal of truth as "superassertibility". Both authors are seeking for a notion of truth that is both absolute and stable (in contrast with warranted assertibility). I will claim that neither of the proposals satisfies these requirements as long as we understand them as generalizations from the mathematical (proof-based) model. (shrink)

“There’s no need for DNA tests to prove that One Hundred Years of Solitude is Don Quixote’s heir.” G. Rabassa This paper is a personal attempt to relate the concept of language games as portrayed by the Austrian Philosopher Ludwig Wittgenstein with the literary magic of Gabriel García Márquez. The topic came up to me after reading an essay of the Colombian writer Carlos Patiño Roselli. His exposition on the language games in Wittgenstein triggered a series ofassociations in me that (...) made me see spoken language as the actor that plays the leading role in both authors. In order to address this topic I will first summarize Wittgenstein’s notion of language-games, on one hand, and then I will remind us of what we commonly understand under “magical realism” in GGM; then, I will propose a free interpretation of §103 in PhU relating it to Melquiades’ return from death to live in a story he tells in some papyrus. And now, “Back to the rough ground!”. (shrink)

Witnessing the fate of the various definitions of truth, Donald Davidson has recently called the very drive to define truth a “folly.” Before him, Kant and Frege had given independent arguments why a general definition of truth is impossible. After a quick summary of their arguments, I recount several reasons that Gangeśa gave for not counting truth as a genuine natural universal. I argue that in spite of defining truth as a feature of personal and ephemeral awareness episodes, the Nyāya (...) ya realists such as Gangeśa could maintain that truth is independent of recognition of truth. In the course of my argument, I also show that Roy Perrett’s alleged proof against realism does not succeed. I conclude that realism does not need nonmental atemporal truth-bearers (propositions) which are eternally wholly true (or wholly false), and that knowledge-independence from truths and things can be shown without admitting the existence of unknowable things or truths.

The vexed issue of the precise connection between words and things has been a major preoccupation over the centuries summoning the resources of metaphysics, philosophy of language, linguistics, ontology and increasingly semiological analysis. Philosophy in India produced a number of different and often conflicting solutions, only to be rivalled by an equally bewildering variety witnessed in the ancient and modern West. I want to bring to the foreground the late Professor Bimal K. Matilal’s development of Nyaya-Vaisesika realist approach to the (...) aporia, and interject the analysis with dissident voices, especially of Mimamsakas and Buddhists. Significantly, it will be the living ghosts of Putnam and Dummett that I will invoke to haunt Matilal’s variation on metaphysical realism. Matilal veered closer to a realist metaphysic, which is inflected in his own formulation of a theory of language appropriate to this ontology, this despite his idealized attraction to phenomenalist-constructivism ; his flirtations with Bhartrharian holism and lately with Derridean deconstruction in his epiloquia. But my critique focuses on his famous earlier analysis of Jnana or cognition and his defence of a particular linguistic-ontology within a narrowly circumscribed naturalized epistemology. (shrink)

On the historically dominant reading of the Fourth Paralogism, Kant pursues an antiskeptical strategy of a Berkeleyan stripe, aiming to secure our belief in the existence of the external world by reducing this world to a mind-dependent, mental entity. I propose a more charitable and realist interpretation of Kant’s strategy. On the proposed reading, Kant pursues a moderate antiskeptical strategy which sets radical skeptical worries aside; Kant’s Berkeleyan-sounding remarks merely express standard Kantian doctrine (his theory of space).

Ethical antirealists believe the words ‘good’ and ‘bad’, and ‘right’ and ‘wrong’, do not signify properties that objects and actions have or might have. They believe that when a person calls pain or any other event ‘bad’ and adultery or any other action ‘wrong’, he does not report some fact about that object or action. J. L. Mackie defends ethical anti-realism in part by appealing to an ontological queerness he believes value properties would have if they existed. "If there (...) were objective values," Mackie writes, "they would be entities or qualities or relations of a very strange sort, utterly different from anything else in the universe." Goodness would have a queer magnetic power. "Something's being good both tells the person who knows this to pursue it and makes him pursue it. An objective good would be sought by anyone who was acquainted with it, not because of any contingent fact that this person, or every person, is so constituted that he desires this end, but just because the end has to-be-pursuedness somehow built into it," Mackie says. If there were a property of the sort we conceive of good as being, it would be a queer property—one we cannot reasonably believe exists, Mackie argues. (shrink)

Most contemporary proponents of scientific realism advocate some form of selective realism. One of the most prominent variants is the working posits view, which claims that the essential propositions of a successful theory are those that are involved in the actual derivations of predictions. In this paper, I offer a systematic examination of this view, surveying no fewer than six competing interpretations of it. I argue, however, that none is satisfactory. A general reason to reject the working posits (...) view is that it focuses on individual successful derivations, as opposed to the empirical success of a theory as a whole. In response to this, I suggest an alternative positive view, which regards as essential those theoretical posits which “unify” a diverse or large collection of other posits. (shrink)
