Quine’s thesis of underdetermination is significantly weaker than it has been taken to be in the recent literature, for the following reasons: (i) it does not hold for all theories, but only for some global theories, (ii) it does not require the existence of empirically equivalent yet logically incompatible theories, (iii) it does not rule out the possibility that all perceived rivalry between empirically equivalent theories might be merely apparent and eliminable through translation, (iv) it is not a fundamental thesis (...) within Quine’s philosophy, and (v) it does not carry with it the anti-realistic consequences often associated with the thesis in recent debates. The paper analyzes Quine’s views on the matter and the changes they underwent over the years. A conjecture is put forth about why Quine’s thesis has been so widely misrepresented: Quine’s writings up to 1975 tackled primarily the formulation and justification of the thesis, but afterwards were concerned mostly with the question whether empirically equivalent rivals to the theory we hold are to be considered true also. When this latter discussion is read without bearing in mind Quine’s earlier formulation and justification of the thesis, his thesis seems to have stronger epistemic consequences than it actually does. A careful reading of his later writings shows, however, that the formulation of the thesis remained unchanged after 1975, and that his mature and considered views supported only a very mitigated version of the thesis.

Many solutions of the Goodman paradox have been proposed but so far no agreement has been reached about which is the correct solution. However, I will not contribute here to the discussion with a new solution. Rather, I will argue that a solution has been in front of us for more than two hundred years because a careful reading of Hume's account of inductive inferences shows that, contrary to Goodman's opinion, it embodies a correct solution of the paradox. Moreover, the (...) account even includes a correct answer to Mill's question of why in some cases a single instance is sufficient for a complete induction, since Hume gives a well-supported explanation of this reliability phenomenon. The discussion also suggests that Bayesian theory by itself cannot explain this phenomenon. Finally, we will see that Hume's explanation of the reliability phenomenon is surprisingly similar to the explanation given lately by a number of naturalistic philosophers in their discussion of the Goodman paradox.

The book from which these sections are excerpted is concerned with the prospects for assimilating the study of human intelligence and its products to the natural sciences through the investigation of cognitive structures, understood as systems of rules and representations that can be regarded as “mental organs.” These mental structui′es serve as the vehicles for the exercise of various capacities. They develop in the mind on the basis of an innate endowment that permits the growth of rich and highly articulated (...) structures along an intrinsically determined course under the triggering and partially shaping effect of experience, which fixes parameters in an intricate system of predetermined form. It is argued that the mind is modular in character, with a diversity of cognitive structures, each with its specific properties arid principles. Knowledge of language, of the behavior of objects, and much else crucially involves these mental structures, and is thus not characterizable in terms of capacities, dispositions, or practical abilities, nor is it necessarily grounded in experience in the standard sense of this term.Various types of knowledge and modes of knowledge acquisition are discussed in these terms. Some of the properties of the language faculty are investigated. The basic cognitive relation is “knowing a grammar”; knowledge of language is derivative and, correspondingly, raises further problems. Language as commonly understood is not a unitary phenomenon but involves a number of interacting systems: the “computational” system of grammar, which provides the representations of sound and meaning that permit a rich range of expressive potential, is distinct from a conceptual system with its own properties; knowledge of language must be distinguished from knowledge of how to use a language; and the various systems that enter into the knowledge and use of language must be further analyzed into their specific subcomponents.

The notion of similarity plays a central role in Quine's theory of Universals and it is with the help of this notion that Quine intends to define the concept of kind which also plays a central role in the theory. But as Quine has admitted, his attempts to define kinds in terms of similarities were unsuccessful and it is mainly because of this shortcoming that Quine's theory has been ignored by several philosophers. Nominalism and realism: Universals and Scientific realism. Cambridge: (...) Cambridge University Press).

Mind, 105, 1-80.] and I will argue that, contrary to what has been claimed by Oliver in a comment on Lewis [. On the plurality of worlds. Oxford: Blackwell.], Quine is able to specify an important set of sparse properties. (shrink)

In this brief space I want to describe how Chomsky's analysis of "psychological reality" departs from what I think is a fairly standard construal of the idea. This familiar formulation arises from distinguishing between someone's following a rule and someone's acting in conformity with a rule. The former idea, but not the latter, involves the idea that the person has some mental representation of the rule that plays a certain causal role in determining behavior. Although there may be many grammatical (...) rules to which a person's verbal behavior (ignoring slips of the tongue and other performance interferences) conforms, only some of those rules have psychological reality; these are the ones that are internalized in thought and play some appropriate causal role.

One usually speaks of Hume's problem of induction in the singular, as if Hume had called our attention to only one problem which affects the justification of inductive inferences. But Hume shows that this justification depends on two assumptions which are not logically valid. In most studies about the justification of inductive inferences, Hume's approach to base the justification on two assumptions has not been discussed. This seems to have been a mistake, however. Not only do these assumptions play different (...) roles in the justification, but by distinguishing between them, one of them can be shown to be scientifically (though not logically) valid.

Despite their divergent metaphysical assumptions, Reformed and evolutionary epistemologists have converged on the notion of proper basicality. Where Reformed epistemologists appeal to God, who has designed the mind in such a way that it successfully aims at the truth, evolutionary epistemologists appeal to natural selection as a mechanism that favors truth-preserving cognitive capacities. This paper investigates whether Reformed and evolutionary epistemological accounts of theistic belief are compatible. We will argue that their chief incompatibility lies in the noetic effects of sin (...) and what may be termed the noetic effects of evolution, systematic tendencies wherein human cognitive faculties go awry. We propose a reconceptualization of the noetic effects of sin to mitigate this tension. (shrink)

Keywords: W.V.Quine claimed that relativism is paradoxical and unacceptable; nevertheless, his own views concerning truth and the underdetermination of theories by data amount to an interesting and plausible form of relativism.

This essay is concerned with solipsism, understood as the extreme sceptical view that I have no knowledge except of my subjective state. A less rough formulation of the view is mooted, inspired by a Quinean combination of naturalism and empiricism. An objection to the resultant position is then considered, based on Putnam’s argument that we are not brains in vats. This objection is first outlined, then pitted against a series of counter-objections. Eventually it is endorsed, but only at the price (...) of exposing the formulation of solipsism in question as not, after all, a satisfactory formulation. This leads to further speculation about the status of solipsism itself. Two of the possibilities that are considered are, firstly, that it is incoherent and, secondly, that it is inexpressible.

This essay reconsiders Davidson's critical attribution of the scheme‐content distinction to Quine's naturalized epistemology. It focuses on Davidson's complaint that the presence of this distinction leads Quine to mistakenly construe neural input as evidence. While committed to this distinction, Quine's epistemology does not attempt to locate a justificatory foundation in sensory experience and does not then equate neural intake with evidence. Quine's central epistemological task is an explanatory one that attempts to scientifically clarify the route from stimulus to science. Davidson's (...) critical remarks wrongly assign concerns to Quine's view that it does not have and further obscures the status of his naturalized conception of epistemology. (shrink)

Quine’s thesis of the indeterminacy of translation has puzzled the philosophical community for several decades. It is unquestionably among the best known and most disputed theses in contemporary philosophy. Quine’s classical argument for the indeterminacy thesis, in his seminal work Word and Object, has even been described by Putnam as “what may well be the most fascinating and the most discussed philosophical argument since Kant’s Transcendental Deduction of the Categories” (Putnam, 1975a: p. 159).

In the wake of Frege's attack on psychologism and the subsequent influence of Logical Positivism, psychological considerations in philosophy came to be viewed with suspicion. Philosophical questions, especially epistemological ones, were viewed as 'logical' questions, and logic was sharply separated from psychology. Various efforts have been made of late to reconnect epistemology with psychology. But there is little agreement about how such connections should be made, and doubts about the place of psychology within epistemology are still much in evidence. It (...) therefore remains to be clarified just how such links should be established, and what impact they would have on the direction of epistemology. (shrink)

Quine has long maintained in connection with his theses of under-determination of physical theory and indeterminacy of translation that there is a fact of the matter to physics but no fact of the matter to translation. In this paper, I investigate Quine's reasoning for this claim. I show that Quine's thinking about under-determination over the last twenty-five years has landed him in a contradiction: he says of two global physical theories that are empirically equivalent but logically incompatible that only one (...) is trueand that they are both true. In accord with the former position, I explain Quine'ssemantical argument for the claim that there is a fact of the matter to physics but not to translation. However, Quine has apparently come to regard this position as inconsistent with his empiricistic scruples: if both theories imply all and only true observation categoricals, then in what sense could one of them be false? Quine'strivial expedient argument construes such pairs of theories as merely two true descriptions of the same world in different terms. In accord with this latter position, I suggest that Quine is left without a way to differentiate under-determination and indeterminacy. In short, Quine's contradiction poses a serious dilemma: either only one such theory is true and his empiricism is sacrificed, or both theories are true and his distinction between under-determination and indeterminacy is sacrificed.

The notion of similarity plays a central role in Quine’s theory of Universals and it is with the help of this notion that Quine intends to define the concept of kind which also plays a central role in the theory. But as Quine has admitted, his attempts to define kinds in terms of similarities were unsuccessful and it is mainly because of this shortcoming that Quine’s theory has been ignored by several philosophers (see, e.g., Armstrong, D.

In the present paper, I propose an alternative framework that accounts for the phenomena that Quine intends to explain with his resemblance theory. The framework agrees with Quine’s austere ontology; in particular, it does not assume the existence of properties and of possible worlds. (I will mention below Quine’s reason for rejecting properties and possible worlds. For a theory of Universals that assumes possible worlds, see, e.g., Rodriguez-Pereyra, G. (2002). Resemblance nominalism: A solution to the problem of Universals. Oxford: Clarendon Press.)

Quine’s notion of fact of the matter has received very little attention, although a good grasp of it is crucial to an understanding of some of Quine’s famous formulations of the indeterminacy of translation thesis. The notion is used and cited by many but has to my knowledge never been thoroughly analysed. In the present article, I attempt to analyse and clarify it. In the first section, my exposition focuses on the relations Quine has developed between his notion of fact (...) of the matter and his views on physicalism and ontology. The main conclusion of this section is that Quine’s notion of fact of the matter is ontological. That is to say, for Quine, the notion concerns extralinguistic reality, which is ultimately described by physics. In the second section, I try to show what relations Quine sees between facts of the matter and truth. The main conclusion of this section is that, for Quine, facts of the matter determine truth. This determination is to be understood in the context of Quine’s genetic approach to evidence, which reveals that it is through the mechanism of conditioned response that facts of the matter determine truth. It is hoped that the present analyses will shed new light on Quine’s controversial indeterminacy of translation thesis as well as on the asymmetry that Quine sees between that thesis and underdetermination of theory.

Quine and Davidson employ proxy functions to demonstrate that the use of language (behaviouristically conceived) is compatible with indefinitely many radically different reference relations. They also believe that the use of language (behaviouristically conceived) is all that determines reference. From this they infer that reference is indeterminate, i.e. that there are no facts of the matter as to what singular terms designate and what predicates apply to. Yet referential indeterminacy yields rather dire consequences. One thus does wonder whether one can (...) hold on to a Quine--Davidson stance in semantics-cum-metaphysics and still avoid embracing referential indeterminacy. I argue that one can. Anyone adhering to the behaviouristic account pivotal to the Quine--Davidson stance is bound to acknowledge certain facts about verbal behaviour -- that some utterances are tied to situations, that some utterances are tied to segments in situations, that some predicates have non-contextualised conditions of application, and that use involves causal dependencies. The restrictions from these facts ensure that only reference relations generated by means of rather exceptional proxy functions are compatible with verbal behaviour. I conclude that this allows one to rebuff the Quine--Davidson argument for the indeterminacy of reference, as it were, from within. I moreover tentatively conclude that the line of thought laid out provides good reason for just about anyone to hold that there are facts about reference after all. (shrink)

Social scientists have not integrated relevant knowledge from the biological sciences into their explanations of human behavior. This failure is due to a longstanding antireductionistic bias against the natural sciences, which follows on a commitment to the view that social facts must be explained by social laws. This belief has led many social scientists into the error of reifying abstract analytical constructs into entities that possess powers of agency. It has also led to a false nature-culture dichotomy that effectively undermines (...) the place of biology in social scientific explanation. Following the principles of methodological individualism, we show how behavioral explanations supported by data and theory from the neurosciences can be used to correct the errors of reificationist thinking in the social sciences. We outline a mechanistic approach to the explanation of human behavior with the hope that the biological sciences will begin to find greater acceptance among social scientists. (shrink)

W. V. Quine describes himself as a “robust realist” about physical objects in the external world. This realism about objects is due to Quine's naturalism. On the other hand, Quine's naturalistic epistemology involves a conception of objects as posits that we introduce in our theories about the world. This conception of objects can be seen as anti-realist rather than realist. In this article, I discuss the questions whether there is a tension between Quine's realism and his epistemological conception of objects, (...) and how Quine's conception of objects should be understood if he is also to be regarded as a realist. I also address the question whether Quine should be placed on the realist or the anti-realist side of the current realism debate. I argue that Quine's conception of objects as posits is a general account of the nature of objects, and that this account does not conflict with Quine's realism as long as this realism is properly understood. I also argue that Quine cannot be placed on either side of the contemporary realism debate, since his realism is not metaphysical realism and his conception of objects is not an anti-realist doctrine according to which objects would be less than real.

In this paper, I raise some questions about Pritchard ’s internalist argument for scepticism. I argue that his internalism begs the question in support of scepticism. Correlatively I advance what I take to be a better internalist argument for scepticism, one that leaves open the possibility of empirically adjudicating sceptical hypotheses. I close by discussing what it means to be an internalist.

In recent years there has been a great deal of discussion about the prospects of developing a “naturalized epistemology,” though different authors tend to interpret this label in quite different ways.1 One goal of this paper is to sketch three projects that might lay claim to the “naturalized epistemology” label, and to argue that they are not all equally attractive. Indeed, I’ll maintain that the first of the three – the one I’ll attribute to Quine – is simply incoherent. There (...) is no way we could get what we want from an epistemological theory by pursuing the project Quine proposes. The second project on my list is a naturalized version of reliabilism. This project is not fatally flawed in the way that Quine’s is. However, it’s my contention that the sort of theory this project would yield is much less interesting than might at first be thought.

Naturalists seek continuity between epistemology and science. Critics argue this illegitimately expands science into epistemology and commits the fallacy of scientism. Must naturalists commit this fallacy? I defend a conception of naturalized epistemology which upholds the non-identity of epistemic ends, norms, and concepts with scientific evidential ends, norms, and concepts. I argue it enables naturalists to avoid three leading scientistic fallacies: dogmatism, one dimensionalism, and granting science an epistemic monopoly.

This article starts from the assumption that there are various innate contributions to our view of the world and explores the epistemological implications that follow from this. Specifically, it explores the idea that if certain components of our worldview have an evolutionary origin, this implies that these aspects accurately depict the world. The simple version of the argument for this conclusion is that if an aspect of mind is innate, it must be useful, and the most parsimonious explanation for its (...) usefulness is that it accurately depicts the world. There are a number of important criticisms of this argument. These include the idea that evolutionary justifications are circular, that evolved mental content and principles are not necessarily accurate, and that, if the argument is taken seriously, it has some highly dubious consequences. These criticisms necessitate various qualifications to the initial argument. Nonetheless, it is argued that, in some cases, important conclusions can be drawn about the world from an analysis of evolved contributions to our view of the world. An evolutionary approach cannot provide an ultimate justification for any belief; however, in certain circumstances, it supports the conclusion that a given belief is a reasonable first approximation. To the extent that innate content and principles pertain to topics in metaphysics, they can be viewed as a naturalistic source of metaphysical knowledge. (shrink)

Jerry Fodor and Ernest Lepore [(1992) Holism: a shopper's guide, Oxford: Blackwell; (1996) in R. McCauley (Ed.) The Churchlands and their critics , Cambridge: Blackwell] have launched a powerful attack against Paul Churchland's connectionist theory of semantics--also known as state space semantics. In one part of their attack, Fodor and Lepore argue that the architectural and functional idiosyncrasies of connectionist networks preclude us from articulating a notion of conceptual similarity applicable to state space semantics. Aarre Laakso and Gary Cottrell [(1998) (...) in M. A. Gernsbacher & S. Derry (Eds) Proceedings of the 20th Annual Conference of the Cognitive Science Society, Mahway, NJ: Erlbaum; Philosophical Psychology ] 13, 47-76 have recently run a number of simulations on simple feedforward networks and applied a mathematical technique for measuring conceptual similarity in the representational spaces of those networks. Laakso and Cottrell contend that their results decisively refute Fodor and Lepore's criticisms. Paul Churchland [(1998) Journal of Philosophy, 95, 5-32 ] goes further. He uses Laakso and Cottrell's neurosimulations to argue that connectionism does furnish us with all we need to construct a robust theory of semantics and a robust theory of translation. In this paper I shall argue that whereas Laakso and Cottrell's neurocomputational results may provide us with a rebuttal of Fodor and Lepore's argument, Churchland's conclusion is far too optimistic. In particular, I shall try to show that connectionist modelling does not provide any objective criterion for achieving a one-to-one accurate translational mapping across networks. (shrink)

My concern in what follows is to give a comparative report on some important lectures held at the Hegel-Kongreß 1981 in Stuttgart. In discussing the views of Quine, Hacking, Davidson, Putnam and Habermas I want to confront them with some details of Rorty's recent critique of our philosophical tradition. At last I try to give a tentative answer whether there is an end or a turning-point for current analytical philosophy.

The idea of there being “no fact of the matter” (NFM) features centrally in Quine’s indeterminacy theses. Yet there has been little discussion of how exactly Quine understands this idea. In this paper I identify, develop and then critically evaluate Quine’s conception of NFM. In Sects. 3–4 I consider a handful of intuitive semantic and ontological conceptions of NFM and argue that none is workable from within Quine’s philosophy. I conclude that the failure of each of these proposals is due (...) to the immanent status of truth and existence for Quine. In Sect. 5 I then present Quine’s official conception of NFM. Briefly, Quine’s idea is that there is NFM between two theories of translation iff those theories are physically equivalent. I develop this idea in detail. Finally, I raise two independent problems for this conception of NFM. In Sect. 6 I argue that Quine’s definition is too strong: given what he means by NFM, his arguments for indeterminacy—even granting all their premises and internal reasoning—simply cannot support his claim that there is NFM regarding translation; instead they establish a strictly weaker conclusion. In Sect. 7 I argue that Quine’s conception of NFM is in significant tension with his thesis of physicalism, and that he must give up one or the other. (shrink)

What are the consequences of evolutionary theory for the epistemic standing of our beliefs? Evolutionary considerations can be used to either justify or debunk a variety of beliefs. This paper argues that evolutionary approaches to human cognition must at least allow for approximately reliable cognitive capacities. Approaches that portray human cognition as so deeply biased and deficient that no knowledge is possible are internally incoherent and self-defeating. As evolutionary theory offers the current best hope for a naturalistic epistemology, evolutionary approaches (...) to epistemic justification seem to be committed to the view that our sensory systems and belief-formation processes are at least approximately accurate. However, for that reason they are vulnerable to the charge of circularity, and their success seems to be limited to commonsense beliefs. This paper offers an extension of evolutionary arguments by considering the use of external media in human cognitive processes: we suggest that the way humans supplement their evolved cognitive capacities with external tools may provide an effective way to increase the reliability of their beliefs and to counter evolved cognitive biases.

Quine's ethical views typify what might seem to be natural sympathies between empiricism and ethical noncognitivism. LikeAyer, he sees a case for noncognitivism rooted in an epistemic discontinuity between ethics and science. Quine argues that the absence of genuine moral observation sentences, and thus the absence of empirical checkpoints for the resolution of theoretical disputes, renders ethics, as he terms it, “methodologically infirm” However, recent papers in this journal make clear that Quine appears to be voicing mutually incompatible commitments to (...) both noncognitivism and cognitivism. Here I argue that Davidson's theory of interpretation offers promising ways to resolve these tensions. His constructive program fleshes out the implications of Quine's largely destructive critique of intensional semantics and contains a fairly well‐articulated account of evaluative semantics, one which seems to combine cognitivist and noncognitivist elements harmoniously. Moreover, it is argued that Davidson's long‐standing differences with Quine over the epistemological status Quine accords observation sentences with do not undermine Quine's metaethical critique.

Central elements of W. V. Quine’s epistemology are widely and deeply misunderstood, including the following. He held from first to last that our evidence consists of the stimulations of our sense organs, and of our observations, and of our sensory experiences; meeting the interpretive challenge this poses is a sine qua non of understanding his epistemology. He counted both “This is blue” and “This looks blue” as observation sentences. He took introspective reports to have a high degree of certainty. He (...) endorsed outright Hume’s “skeptical” argument concerning induction. His naturalized epistemology is simply naturalistic, or scientific, epistemology stripped of the project of rational reconstruction, and is thoroughly normative. Quine was unconditionally a scientific philosopher who took our theories to be answerable ultimately to our perceptual experiences (sensations)—and conditionally an empiricist, empiricism being a scientific theory that has no competitors worthy of the name. I attempt to make all of this clear, and conclude by offering a concise formulation of his epistemology. (shrink)

La thèse de l'indétermination de la traduction de W. V. O. Quine est certainement une des thèses les plus controversées de la philosophie du langage. Le présent article explique en quoi consiste cette thèse et examine les liens qu'elle entretient avec la thèse de la sous-détermination des théories scientifiques. La première section montre comment la thèse de l'indétermination de la traduction découle de la conception behavioriste du langage de Quine. Les sections suivantes exposent deux façons de dériver la thèse de (...) l'indétermination: par le holisme et le vérificationnisme dans la section 2 et par la thèse de la sous-détermination dans la section 3. La section 4 précise la formulation de la thèse de la sous-détermination proposée dans «On Empirically Equivalent Systems of the World» et la section 5 expose les critiques exprimées par W. Bechtel à propos de cette formulation. Ces critiques témoignent d'une mauvaise compréhension de la position de Quine et j'essaierai de montrer en quoi elles sont fautives. La section 6 traite des deux façons de dériver la thèse de l'indétermination, à la lumière des modifications apportées à la formulation de la thèse de la sous-détermination. Enfin, la section 7 s'intéresse aux questions de fait relatives à la sous-détermination des théories et à l'indétermination de la traduction. (shrink)

I juxtapose Quine's and Davidson's approaches to naturalized epistemology and assess Davidson's reasons for rejecting Quine's account of the nature of knowledge. Davidson argues that Quine's account of the nature of knowledge is Cartesian in spirit and consequence, i.e. it is essentially first person and invites global skepticism. I survey Quine's response to Davidson's criticisms and suggest that the view that Davidson criticizes may not be Quine's after all. I conclude by raising some questions about Quine's definition of ?observation sentence?
