In this paper we discuss some questions proposed by Prof. Newton da Costa on the foundations of quasi-set theory. His main doubts concern the possibility of a reasonable semantical understanding of the theory, mainly due to the fact that identity and difference do not apply to some entities of the theory’s intended domain of discourse. According to him, the quantifiers employed in the theory, when understood in the usual way, rely on the assumption that identity applies to all entities in (...) the domain of discourse. Inspired by his provocation, we suggest that, using some ideas presented by da Costa himself in his seminars at UFSC and by one of us in some papers, these difficulties can be overcome both on a formal level and on an informal level, showing how quantification over items for which identity does not make sense can be understood without presupposing a semantics based on a ‘classical’ set theory.

In a circulated but heretofore unpublished 2001 paper, I argued that Leiter's analogy to Quine's 'naturalization of epistemology' does not do the philosophical work Leiter suggests. I revisit the issues in this new essay. I first show that Leiter's replies to my arguments fail. Most significantly, if — contrary to the genuinely naturalistic reading of Quine that I advanced — Quine is understood as claiming that we have no vantage point from which to address whether belief in scientific theories is (...) ever justified, it would not help Leiter's parallel. Given Leiter's way of drawing the parallel, the analogous position in the legal case would be not the Legal Realists' indeterminacy thesis, but the very different position that we have no vantage point from which to address whether legal decisions can ever be justified. I then go on to address the more important question of whether the indeterminacy thesis, if true, would support any replacement of important legal philosophical questions with empirical ones. Although Ronald Dworkin has argued against the indeterminacy thesis, if he were wrong on this issue, it would not in any way suggest that the questions with which Dworkin is centrally concerned cannot fruitfully be addressed. The indeterminacy thesis is a bone of contention in an ordinary philosophical debate between its proponents and Dworkin. Of course, if the determinacy thesis were true, no one should try to show that it is false, but this triviality lends no support to the kind of replacement proposal that Leiter proposes. I conclude with some general reflections on naturalism and philosophical methodology. (shrink)

La thèse d’indétermination de Quine est souvent considérée comme découlant de l’adoption d’un point de vue naturaliste. Contre cette lecture, qui manque la distinction entre empirisme et naturalisme, nous montrons comment l’indétermination est fondée dans une philosophie demeurant empiriste malgré la critique des deux dogmes de l’analyticité et du réductionnisme. Cet empirisme entre en conflit avec certaines thèses de l’épistémologie naturalisée défendue par Quine.Quine’s thesis of indeterminacy is often seen as grounded in his naturalism. Against this interpretation, which confuses empiricism (...) with naturalism, we show how indeterminacy is grounded in a philosophy which remains empiricist albeit the rejection of analyticity and reductionism. This empiricism conflicts with some theses of naturalized epistemology. (shrink)

Our ability for scientific reasoning is a byproduct of cognitive faculties that evolved in response to problems related to survival and reproduction. Does this observation increase the epistemic standing of science, or should we treat scientific knowledge with suspicion? The conclusions one draws from applying evolutionary theory to scientific beliefs depend to an important extent on the validity of evolutionary arguments (EAs) or evolutionary debunking arguments (EDAs). In this paper we show through an analytical model that cultural transmission of scientific (...) knowledge can lead toward representations that are more truth-approximating or more efficient at solving science-related problems under a broad range of circumstances, even under conditions where human cognitive faculties would be further off the mark than they actually are.

A tempting solution to problems of semantic vagueness and to the Liar Paradox is an appeal to truth-value gaps. It is tempting to say, for example, that, where Harry is a borderline case of bald, the sentenceHarry is baldis neither true nor false: it is in the ‘gap’ between these two values, and perhaps deserves a third truth-value. Similarly with the Liar Paradox. Consider the following Liar sentence: is false.That is, sentence says of itself that it is false. If we (...) accept the Tarskian schema S is true iff pwhere ‘S’ is a name of a sentence ‘p,’ we are led into paradox. Both the assumption that is true, and the assumption that is false lead us, via, to is true if and only if is false.Given this result, a natural reaction is to place in a ‘gap’ between true and false.

It is sometimes objected that anti-individualism, because of its assumption of the constitutive role of natural and social environments in the individuation of intentional attitudes, raises sceptical worries about first-person authority--that peculiar privilege each of us is thought to enjoy with respect to non-Socratic self-knowledge. Gary Ebbs believes that this sort of objection can be circumvented, if we give up metaphysical realism and scientific naturalism and adopt what he calls a “participant perspective” on our linguistic practices. Drawing on broadly Wittgensteinian (...) considerations, I argue that Ebbs is right about this, and I show how two likely objections to his view can be circumvented. I also argue that mere adoption of the participant perspective does not serve to refute external-world sceptic. (shrink)

Dummettian anti-realism–the refusal to endorse bivalence–is generally thought to be associated with idealism This paper argues that this is only true of the position developed by early Dummett. In a later manifestation Dummettian anti-realism is better thought of as providing the logic for anti-realisms of an error theoretic kind. Early on Dummett distinguished deep from shallow arguments for giving up bivalence: deep arguments followed a strong ‘sufficiency’ reading of Frege’s context principle, and made the sentence the primary vehicle of meaning. (...) Enriched by an account of truth in terms of verifiability, deep arguments implied a form of linguistic idealism. From within a perspective that had already made ontology relative to theory, it was natural for the difference between realism and idealism to hinge on the notion of truth for sentences. Having given up the distinction between deep and shallow arguments against bivalence, Dummett, post 1990, asserts that every rejection of bivalence leads to a form of anti-realism. In the intervening years, he has also come to cast doubt on the sufficiency reading of the context principle, particularly as developed by Crispin Wright. These doubts open the space for some more simple-minded criticisms of this strong version of the context principle, developed in the paper. Once the sufficiency reading of the context principle is given up, arguments for failing to assert bivalence come to hinge on beliefs about ‘genuine’ existence. These forms of anti-realism cannot be taken to imply idealism. Rather, in many cases they will be the expression of views of an error-theoretic kind, that are quite compatible with a thorough-going rejection of idealism. (shrink)

The claims of the epistemological 'anarchists' have their roots in the orthodox tradition as well as in the Popperian. In particular they follow from the work of Quine. Meaning variance and incommensurability follow directly from the holistic conception of meaning in his 'network' view. Quine's efforts to evade this conclusion fail. His attempt to develop a theory-neutral notion of observation sentence is shown (1) to be inconsistent with his previous claims since it involves the tacit acceptance of the 'dogma of (...) reductionism', (2) to involve the acceptance of a questionable 'third dogma', i.e. the stimulus-response theory of behaviorist psychology, and (3) ultimately to miss the point of the anarchists. In Quinian terms, in order for observation sentences to perform the function of intertheoretical 'arbiters', what is needed is 'similarity of assent', which is not a meaningful notion on an internetwork basis.

Byrne & Hilbert defend color realism, which assumes that: (a) colors are properties of objects; (b) these objects are physical; hence, (c) colors are physical properties. I accept (a), agree that in a certain sense (b) can be defended, but reject (c). Colors are properties of perceptual objects – which also have underlying physical properties – but they are not physical properties.

A detailed analysis of Quine's paper on ontologicalreduction shows that the proxy-function requirement, in hischaracterization of the concept of ontological reduction,is superfluous for blocking Pythagoreism and inappropriate for a generalblockade of ontological monism.

I revisit my 1993 paper on Putnam and mathematical realism focusing on the indispensability argument and how it has fared over the years. This argument starts from the claim that mathematics is an indispensable part of science and draws the conclusion, from holistic considerations about confirmation, that the ontology of science includes abstract objects as well as the physical entities science deals with.

Wittgenstein’s writings on religious and magical beliefs, especially the “Lectures on Religious Belief” and “Remarks on Frazer’s Golden Bough” are taken to imply semantic incommensurability and inaccessibility by the Wittgensteinian Fideism and, in part, the expressivist interpretation. According to these interpretations, religious and non-religious discourses are self-contained, closed, and not intertranslatable. Wittgenstein is taken to deny mutual understanding between believers and non-believers with respect to religious and magical discourse. I argue against such interpretations and support readings by Kusch, Schroeder, and (...) Tripodi that are optimistic of the possibility of mutual understanding. Nevertheless, there is a danger of scepticism for such optimistic readings when they refer to a special attitude that is needed to understand religious belief and speech. I offer a reply to this problem and suggest to see Wittgenstein’s stance on understanding religious discourse in a greater proximity to his general views about language in his later writings. Then, however, any fideist view of the religious form of life as self-contained and isolated from the non-religious has to be repudiated. (shrink)

In this paper, I argue that Imre Lakatos’s account on the relation between the history and the philosophy of science, if properly understood and also if properly modified, can be valuable for the philosophical comprehension of the relation between the history and the philosophy of science. The paper is divided into three main parts. In the first part, I provide a charitable exegesis of the Lakatosian conception of the history of science in order to show that Lakatos’s history cannot be (...) a caricature. In the second part, I describe what I believe are the real problems of Lakatos’s account on a metaphysical and on a methodological level. In order to address these problems, I take advantage of the recent critique of the so-called “confrontation model”. Finally, in the third part, I suggest that a proper modification of Lakatos’s perspective can resolve the aforementioned problems without distorting Lakatos’s central aspiration, which is that the philosophical theories of scientific rationality can be assessed with the help of the history of science without losing their normative content.

In “Empiricism, Semantics, and Ontology” Camap drew his famous distinction between ‘internal’ and ‘external’ questions of existence, pronouncing the former meaningful and the latter meaningless. In The Significance of Philosophical Scepticism, Barry Stroud understands Carnap to be applying the verification criterion of meaningfulness in order to refute Cartesian skepticism. I suggest that Stroud misrepresents both Carnap's aim and method. Camap was responding to critics who suggested that his willingness to quantify over abstract entities in his work in semantics violated his (...) commitment to empiricism. He rejected that criticism as presupposing a super‐scientific standpoint from which constraints on the admissible domain of entities of science could be delivered. Carnap wanted to insulate science from the imposition of first‐philosophical metaphysical prejudice, not to defuse scepticism by appeal to verificationism. (shrink)

The analysis here is an attempt to show how the current epistemological theory of response‐dependence (R‐D) may be relevant to understanding putative ontological claims of the empirical social sciences. To this end I argue that the constitutive features of human response, central to R‐D theory, can be made explicit for social science. I conclude that for the empirical social sciences the implication of combining R‐D and certain forms of statistical analyses leads to the possibility of an events‐based ontology.

“There ceases to be any reason to count awareness as an essential trait of observation.”-from “Stimulus and Meaning”As W. V. Quine sees it we must, in the interests of science, resist “the old tendency to associate observation sentences with a subjective sensory subject matter,” because such sentences are “meant to be the intersubjective tribunal of scientific hypotheses“; observation sentences are meant to be the independent and objective control of scientific theory. Accordingly, Quine has developed a behaviouristic operational definition of an (...) observation sentence for the purpose of dispelling the air of subjectivity which surrounds the notion of observation.In this paper I argue that his observation-sentence definition, or criterion, fails to fulfil this purpose. In the first half of the paper, I describe in particular the kind of subjectivism which most worries Quine-what he calls the epistemological nihilism of Hanson, Kuhn and Polanyi-and I then turn to Quine's remedy, his observation criterion.

In lieu of an abstract, here is a brief excerpt of the content:F/Actual Knowing:Putting Facts and Values in PlaceHolmes Rolston III (bio)Knowing needs to be actualized, an act of ours, yet also a discovery of what is actually, factually there. In place ourselves, we manage some awareness of other places. Agents in our knowing, we co-respond, and this emplaces us. But we humans have powers of dis-placement too, of taking up, whether empathetically or objectively, the situations of others, other humans, (...) sometimes others than humans. How do our facts depend on our acts? Do we humans always put in place, or sometimes find put, placed there before us, what we variously value on Earth?To put this provocatively: We need to "green" our beliefs; but every educated person knows that nothing out there is really "green." "Seeing green" is an interaction experience. Perhaps this perceptual experience is a model for the whole: all of our human concepts and percepts color up the world. This is true alike of facts and of values, discoveries and evaluations. Such knowing might be well enough placed, but it is always and only "placed." Our geographical position controls our epistemic composition. Epistemology is inevitably anthropocentric; we are always located in the center of our knowing.But what if the "green" we see is mostly chlorophyll? Photosynthesis is not something we can see at all. In place on Earth, we humans breathe oxygen and would die in minutes without it; we depend on photosynthesis at the foundation of our food chains. We know our own respiratory [End Page 137] and trophic interactions with the plants, and this not simply at the native range experiences of breathing and eating. We have figured out the oxygen/carbon-dioxide/water cycles taking place at molecular levels.Now it seems, however, that we are discovering ourselves placed where the facts are bigger than our acts, including our respiratory (and perceptual) interactions; these extend systemically and are hardly anthropocentric. Epistemologically, we have more to evaluate. "Greening" our belief, environmentally grounding it, will require knowing and appropriately respecting these vital life processes—of which we are a part, but which also are "in place" and "take place" apart from us.1. Embodied, Knowledgeable PersonsWhatever knowledge we gain has to "come through" at our native range. That seems uncontroversial, but what are the implications? Knowledge is relative to our location, our embodiment, our size, our terrestrial habitat. This situation constricts, it may be claimed, what can "come through." Mark Johnson concludes: "Our consciousness and rationality are tied to our bodily orientations and interactions in and with our environment. Our embodiment is essential to who we are, to what meaning is, and to our ability to draw rational inferences and to be creative." He urges us to "put the body back into the mind," that is, epistemologically, to become aware of how the body is there, willy-nilly (1987, xxxviii, xxxvi). Joining with George Lakoff, he claims: "Reason, even in its most abstract form, makes use of, rather than transcends, our animal nature" (Lakoff and Johnson 1999, 4).Katherine Hayles continues: "To be incorporated within a different body would be to live in a different world." She features "interactivity" and explains:Interactivity foregrounds rather than obscures the importance of embodiment. In the interaction model, the body does more than provide a biological support system for the mind. Interaction is possible only because we are embodied, and the precise conditions of our embodiment have everything to do with the nature of those interactions. The range and nature of sensory stimuli available to us, the contexts that affect how those sensory stimuli achieve meaning, the habituated movements and postures that we learn through culture and that are encoded for gender, ethnicity, and class—all affect how learning takes place and how the world comes into being for us.(1995, 56) [End Page 138]All this seems true, if one means that with reincarnation our native range experiences would be different. Wolves have keen noses and with them they experience, if you like, a different world. But the survival value of wolf noses, a situated knowledge for them, is equally true for humans, wolves, and elk, because all three... (shrink)

A philosophical movement, correctly called logical pragmatism, is growing up around the philosophy of W. V. O. Quine. Soviet scholars follow this development with clear and well-grounded understanding of the origins and tenets of the system. This essay continues the "dialogue" between contemporary Marxism-Leninism and logical pragmatism recommended by Soviet scholars.

Much of The Reason’s Proper Study is devoted to defending the claim that simply by stipulating an abstraction principle for the “number-of” functor, we can simultaneously fix a meaning for this functor and acquire epistemic entitlement to the stipulated principle. In this paper, I argue that the semantic and epistemological principles Hale and Wright offer in defense of this claim may be too strong for their purposes. For if these principles are correct, it is hard to see why they do (...) not justify platonist strategies that are not in any way “neo-Fregean,” e.g. strategies that treat “the number of Fs” as a Russellian definite description rather than a singular term, or employ axioms that do not have the form of abstraction principles.

In its predominant form, the understanding of the neurosciences, which stand in high public esteem, is a naturalistic one. The critique of this naturalism concerns the technical modelling of brain functions as a syntactic or control loop machine. Adequate solutions to the mind-body problem are not found in this way.

Choice modellers are frequently criticized for failing to provide accurate representations of the neuro-psychological substrates of decisions. Several authors maintain that recent neuro-psychological findings enable choice modellers to overcome this alleged shortcoming. Some advocate a realistic interpretation of neuro-psychological models of choice, according to which these models posit sub-personal entities with specific neuro-psychological counterparts and characterize those entities accurately. In this article, I articulate and defend three complementary arguments to demonstrate that, contrary to emerging consensus, even the best available neuro-psychological (...) models of choice cannot be justifiably given this realistic interpretation. Moreover, I explicate what challenges will continue to hamper neuro-psychological modellers’ attempts to substantiate a realistic interpretation of their models. In doing so, I draw on the literature on scientific modelling to advance the ongoing philosophical discussion concerning the ontological status of the sub-personal entities posited in distinct decision sciences, the resemblance relations that supposedly connect choice models and the neuro-psychological substrates of decisions, and what conditions these models must satisfy to be regarded as realistic representations of their target systems.

Non-cognitive dispositions have recently become psychological constructs of interest in the education, economics, philosophy, sociology, and psychology literature. In this article, I draw the distinction between property-first and measurement-first approaches to understanding the meaning of a particular non-cognitive disposition theoretical term, ‘grit’, as well as the relationship between this term and its corresponding measurement procedure. I argue that, depending on which approach one takes, one is confronted with different norms for judging the success of any disposition-measurement procedure pair, meaning that (...) the difference in philosophical approaches may have practical import. I argue that the measurement-first approach is the one educators and educational policy-makers ought to adopt towards grit as it is less likely to lead to over-valuing grit in situations where a gritty disposition may be harmful, better respects scientific virtues and values, and provides a clearer understanding of grit than the property-first approach.

When explaining the causes of structural variations in local governance reform, regional studies scholars face a trilemma: how to avoid voluntarism that over-inflates individuals’ power to ‘heroically’ reorganize local governance regimes; how to avoid determinism that denies the prowess of local actors in the face of institutional constraints; and how to avoid constructivism that denies the separate existence of both individual actions and local institutions. The question they must answer is: if individuals are embedded in institutions that define their interests (...) and shape their cognitions, how can they ever be able to change institutions? Critical realism suggests a suitable answer to this question by seeing institutional dynamics as consisting of structures, institutions, and actions, each with a distinct existence but nevertheless irreducible to each other. The practical value of this ontology – which avoids voluntarism, determinism and constructivism – is illustrated by an English devolution case study. (shrink)

The problem to be discussed here concerns ontology so far as it may not be formed by scientific theory. In brief terms, the problem arises in the following way. On the one hand, the world surely consists of whatever is there, irrespective of whether human beings are around or not, and irrespective especially of whether human beings have constructed any scientific theories depicting the nature of the world; on the other hand, scientific theories are subject to the limitation that we (...) can never verify them or prove them to be true, so that the ontology prescribed by scientific theory is not firmly established but is only what is attributed to the world by a fallible scientific theory at any given time. The problem could also be put in terms of ‘conceptual networks’ or in terms of language-systems. (shrink)

‘Universalist’ moral principles have fallen into disfavour because too often they have been pretexts for unilateral impositions upon others, whether domestically or internationally. Too widely neglected has been Kant’s specifically Critical re-analysis of the scope and character of rational justification in all non-formal domains, including the entirety of epistemology and moral philosophy, including both justice and ethics. Rational judgment is inherently normative because it is in part constituted by our self-assessment of whether the considerations we now integrate into a candidate (...) judgment have been integrated as they ought, so as to form a cogent, justifiable judgment. Constitutive of this self-assessment is that rational judgments must be based upon considerations which can be communicated to all others, such that they too can assess them as sufficiently cogent justification; also constitutive of this rational self-assessment is that we actually engage with others who do assess our judgments. Kant’s Critical principles rule out in principle any unilateral imposition upon others, whether in cognition or morals. Using Kant’s Critical principles and methods in connection with ‘practical anthropology’ and the enormously important domain of acquired rights and obligations shows how Kant had already justified fundamentally universal principles of justice which can be institutionalised in variously distinctive cultures, and which form the proper bases for our acquired, specifically social rights and obligations, including those of friendship and community.
