The conclusion of the McKinsey paradox is that certain contingent claims about the external world are knowable a priori. Almost all of the literature on the paradox assumes that this conclusion is unacceptable, and focuses on finding a way of avoiding it. However, there is no consensus that any of these responses work. In this paper I take a different approach, arguing that the conclusion is acceptable. First, I develop our understanding of what Evans calls merely superficially contingent a priori (...) knowledge, and explain why there is no reason to deny that merely superficially contingent a priori knowledge of the external world is possible. I then argue that, properly understood, the conclusion of the McKinsey paradox is that merely superficially contingent knowledge of certain claims about the external world is possible, and so the conclusion is acceptable. Finally, I respond to the two main arguments that the conclusion of the paradox is unacceptable. (shrink)

According to Clarke and Beck (C&B), the approximate number system (ANS) represents numbers. We argue that the ANS represents pure magnitudes. Considerations of explanatory economy favor the pure magnitudes hypothesis. The considerations C&B direct against the pure magnitudes hypothesis do not have force.

The theory of object-dependent singular thought is outlined and the central motivation for it, turning on the connection between thought content and truth conditions, is discussed. Some of its consequences for the epistemology of thought are noted and connections are drawn to the general doctrine of externalism about thought content. Some of the main criticisms of the object-dependent view of singular thought are outlined. Rival conceptions of singular thought are also sketched and their problems noted.

El presente ensayo expone las principales ideas de Chomsky acerca de la Nueva Teoría de la Referencia. Contra dicha teoría, y específicamente contra propuestas bien conocidas de Kripke y Putnam, aduce Chomsky distintos argumentos. Las conclusiones de esos argumentos son las siguientes: que en los lenguajes naturales no hay nombres lógicamente puros; que no existe ninguna relación de referencia que conecte las palabras con las cosas; que los conceptos que maneja la así llamada teoría de la referencia no responden a (...) las exigencias metodológicas de la ciencia natural; y que el significado sí «está en la cabeza». Tratando de poner al descubierto los supuestos en que se fundan estas tesis, el ensayo identifica los siguientes cuatro:su naturalismo metodológico, su pragmatismo en materia de ontología, su perspectivismo conceptual y su racionalismo.

According to the scrutability argument against physicalism, an a priori gap between the physical and conscious experience entails a lack of necessitation and the falsity of physicalism. This paper investigates the crucial premise of the scrutability argument: the inference from an a priori gap to a lack of necessitation. This premise gets its support from modal rationalism, according to which there are important, potentially constitutive, connections between a priori justification and metaphysical modality. I argue against the strong form of modal (...) rationalism that underwrites the scrutability argument and suggest a more moderate rationalist view. I offer a novel demonstrative reply to the scrutability argument, according to which demonstratives play a vital role in the generation of meaning for our representations of conscious experience. This connection between conscious experience and demonstratives, rather than a metaphysical gap generated by the truth of dualism, is the source of the epistemic gap between consciousness and the physical.

Las profundas raíces intencionales de los artefactos y sus tipos parecen apoyar intuitiva y filosóficamente una forma de privilegio epistémico de los hacedores con respecto a los objetos que crean. En este artículo examino críticamente la tesis del privilegio epistémico para los creadores de artefactos y presento un contraejemplo basado en el antiindividualismo. Se consideran diversas objeciones a las que se da respuesta. Concluyo que si el antiindividualismo es verdadero, entonces el supuesto privilegio epistémico de los creadores de artefactos o (...) bien es falso, o bien, una etiqueta explicativamente vacía. Defiendo, por último, que incluso si el antiindividualismo nos fuerza a rechazar el privilegio epistémico para tipos artefactuales, estos tipos aún pueden exhibir dependencia mental, tanto semántica como metafísica, algo que los continuaría distinguiendo de los tipos naturales y dejaría intacta su esencial naturaleza intencional.

Agents can think using concepts they do not fully understand. This paper investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I lay out a gauntlet of problems and desiderata with which any theory of concept mastery must cope. I use these considerations to argue against three views of concept mastery, according to which mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. None (...) of these attitudes is either necessary or sufficient for mastery. I propose and respond to objections to my own recognition view of the conditions under which a thinker has mastery of a concept. (shrink)

The skeptical Dream argument appeals to the possibility of dreaming. The skeptic holds that states of being awake are subjectively indistinguishable from possible dream states and that this means that we do not know that we are awake. This, the skeptic then claims, means that we have to accept that we do not have external world knowledge.It is natural to assume that there must be a connection between the Dream argument and epistemic internalism, the view that a belief is justified (...) for a given person if and only if the person has cognitive access to all the factors that are needed for the belief to be justified. The problem, the skeptic thinks, is that in order for my belief that I am awake to be justified I have to have cognitive access to something that establishes that I am awake. But according to the skeptic, even if I am awake, this is not something I have cognitive access to. However, the more precise connections between internalism and the skeptical argument are not so clear. (shrink)

Response to Fernandez-Moreno's contribution in the proceedings of the Granada workshop.

Recent developments in technologically enabled social cognition call for a rethinking of many aspects of human cognition. According to the hypothesis of extended cognition, we must revise our psychological categories by eliminating allegedly superficial distinctions between internal cognition and external processes. As an alternative to this proposal, I outline a hypothesis of outsourced cognition which seeks to respect distinctions that are operative in both folk psychology and the social and cognitive sciences. According to this hypothesis, the cognitive states and processes (...) of the individual are substantially and explanatorily distinct from the relevant external states and processes. In consequence, the individual remains a cognitive unit that is both central and indispensable in the explanations of cognitive science. As a case study, I consider the epistemology of testimony. I will argue that important epistemological categories may be preserved by adopting the hypothesis of outsourced cognition over the hypothesis of extended cognition. Moreover, I will argue that the outsourced cognition hypothesis deepens the problems that beset an extended epistemology of testimony. (shrink)

Externalism holds that the content of our utterances and thoughts are determined partly by the environment. Here, I offer an argument which suggests that externalism is incompatible with a natural view about ontological commitment--namely, the Quinean view that such commitments are fixed by the range of the variables in your theory. The idea in brief is that if Oscar mistakenly believes that water = XYZ, the externalist ontologically commits Oscar to two waterish kinds, whereas the Quinean commits him to one (...) such kind (albeit a metaphysically impossible kind). The penultimate section addresses a variety of objections to the argument. (shrink)

This paper articulates two constraints on an acceptable account of meaning: (i) accessibility: sameness of meaning affords an immediate appearance of de jure co-reference, (ii) flexibility: sameness of meaning tolerates open-ended variation in speakers' substantive understanding of the reference. Traditional accounts of meaning have trouble simultaneously satisfying both constraints. I suggest that relationally individuated meanings provide a promising way of avoiding this tension. On relational accounts, we bootstrap our way to de jure co-reference: the subjective appearance of de jure co-reference (...) helps make it the case that two token representations really do co-refer.

The idea that there is an inherent incentive in moral judgment or, in Classical terms, that there is an essential relationship between virtue and well?being is sharply criticized in contemporary moral theory. The associated theses that there is a way of living which is objectively good for human beings and that living that way is part of understanding moral truth are equally problematic. The Aristotelian argument proceeded via the premise that a human being was a rational social being. The present (...) reworking of that thesis builds on the internal connection between rationality and concept use. Moral judgment is linked to the grasp of moral concepts and thereby to an appreciation of how it is with other persons. The judgment that another person instances a morally relevant ascription is grounded on an empathic grasp of how it is with that person and thus tied to the thought that one ought to act in such and such a way or. in other words, to a disposition to act. Because the empathically grasped content of moral concepts is related to a number of mental ascriptions and reactive attitudes, the grasp of that content is interwoven deeply in the structure of human mental life and any attempt systematically to devalue or undermine it is threatening to one's mental integrity as a rational social being. Thus there is a deep link between moral sense or the disposition to act morally and an adequately grounded conception of human well?being. (shrink)

Quine's (1969) proposal that the foundationalist programs in epistemology should be abandoned in favor of a scientific study of how we come to hold our theories about the world is still widely misunderstood. It does not eliminate the possibility of rational adjudication of scientific dispute, nor is it essentially tied to behaviorist approaches in psychology. On the contrary, recent work in psychology and philosophy of science can very naturally be seen as embodying the sort of program envisioned by Quine; now (...) freed of behaviorist strictures, it clearly addresses issues that have been of interest in traditional epistemology. This view is defended with particular attention to Quine's concerns with translation and the related concerns with belief individuation which have inspired critics of recent cognitive psychology.

Harold Langsam has recently presented a novel observational account of self-knowledge. I critically discuss this account and argue that it fails to provide a uniform understanding of how we are able to know the contents of our own thoughts.

My primary goal in this paper is to focus attention on a certain conception of internal access, on the Cartesian conception that a rational subject's capacity to determine sameness and difference in explicit propositional attitudes is independent of knowledge of the external world. This conception of introspection plays a crucial, if unacknowledged, role in numerous arguments and theoretical positions. In particular, it plays a large role in motivating psychological internalism. I argue in favor of rejecting this epistemology and the internalism (...) it supports. (shrink)

A. Horowitz has recently argued against semantic externalism. In this paper, I will show that his arguments are unsuccessful, owing to misconceptions regarding the nature of that semantic view.

In this paper, I argue from a metasemantic principle to the existence of analytic sentences. According to the metasemantic principle, an external feature is relevant to determining which concept one expresses with an expression only if one is disposed to treat this feature as relevant. This entails that if one isn’t disposed to treat external features as relevant to determining which concept one expresses, and one still expresses a given concept, then something other than external features must determine that one (...) does. I argue that, in such cases, what determines that one expresses the concept also puts one in a position to know that certain sentences are true—these sentences are thus analytic relative to this determination basis. Finally, I argue that there are such cases: some sentences are analytic relative to what determines that we express certain key concepts, and these sentences include ones that have always been thought to be the best candidates for being analytic, namely, stipulative truths, and first principles of mathematics.

An anti-skeptical transcendental argument can be loosely defined as an argument that purports to show that some experience or knowledge of an external world is a necessary condition of our possession of some knowledge, concept, or cognitive ability that we know we have. In this dissertation I examine transcendental arguments by focusing on one such argument given by Immanuel Kant in his Critique of Pure Reason, along with some attempts to interpret that argument by contemporary commentators. ;I proceed by dividing (...) anti-skeptical transcendental arguments into three types: epistemological, verificationist, and psychological. I examine arguments of the first two types and show why they cannot succeed against the skeptic. I then argue that Kant's Refutation of Idealism is of a different type: it is psychological in that it concerns the necessary conditions of our forming beliefs of certain kinds. Many contemporary Kant scholars have claimed that his anti-skeptical strategy relies on phenomenalism or verificationism; I argue, however, that Kant in the Refutation employs a clever and hitherto unappreciated strategy which involves an empiricist principle concerning the origin of simple ideas, and which does not require either phenomenalism or verificationism. I conclude with an analysis and assessment of Kant's argument. (shrink)

The externalist examples of Burge, Putnam etc. were offered as examples of how it is physically identical twins can differ in mental states such as belief, and little attention was paid to the interpretations the twins impose on their respective acoustic inputs. The received story today is that this form of interpretation—the semantic reading one assigns the sounds one hears—is the product of inference. The problem for this inferential model is simple to state: though the twins are physical doppelgangers and (...) don't differ in their acoustic inputs, they differ in the interpretations they impose on their respective inputs. I argue that the inferential model does not allow for how it is the twins arrive at these different interpretations. And, since the externalist examples are compelling, this tells against the inferential model. (shrink)

This paper addresses a problem about epistemic warrant. The problem is posed by philosophical arguments for externalism about the contents of thoughts, and similarly by philosophical arguments for architecturalism about thinking, when these arguments are put together with a thesis of first person authority. In each case, first personal knowledge about our thoughts plus the kind of knowledge that is provided by a philosophical argument seem, together, to open an unacceptably ‘non-empirical’ route to knowledge of empirical facts. Furthermore, this unwelcome (...) prospect of transferring a ‘non-empirical’ warrant from premises about our own mental states and about philosophical theory to a conclusion about external environment or internal architecture seems to depend upon little more than the possibility of knowledge by inference. (The use of the scare-quoted term ‘non-empirical’ is explained a couple of paragraphs further on.). (shrink)

Tyler Burge says that first-person authority can be reconciled with anti-individualism about the intentional by denying part of the "Cartesian conception" of authority, which claims that I am actually authoritative about my intentional attitudes in counterfactual situations. This clause, he says, wrongly conflates the evaluation-conditions for sceptical doubts about the "external" world with the conditions for classifying intentional attitudes in counterfactual situations. This paper argues that the kind of possibility needed to understand external-world scepticism justifies the conflation and that Burge (...) can reject the Cartesian conception only if he rejects either metaphysical realism or anti-individualism.

Semantic externalism Are the meanings of natural kind words, such as “water” or “tiger,” in the head or in the world? This question is pressing and controversial in contemporary philosophy. The nature of the meaning related to propositional contents and words of the natural kind raises a fundamental disagreement between two groups of philosophers: defenders of internalism and defenders of externalism. The two groups differ on how to define meaning. Internalists say that meaning is determined entirely by aspects that are (...) internal to the speaker, and mental contents are semantic contents that are in our minds or heads, their slogan is “Meanings are in the head or brain.” Externalists say that meaning is determined, at least in part, by aspects that are external to the speaker, and that contents are linguistic signs and exist in the outside world, and their slogan is “Meanings do not exist only in the head.” In this article, I want to shed explanatory light on this disagreement by examining its origins, explaining some of the arguments in support of externalism, and demonstrating the impact of this disagreement on understanding the nature of meaning. This article addresses several topics: 1. Various types of externalism 2. Description theory and causal theory 3. Hillary Betnam and Twin Earth thought experiment 4. Tyler Berg and arthritis argument 5. Donald Davidson and perceptual externalism 6.

This article develops a constitutive account of self-knowledgethat is able to avoid certain shortcomings of the standard response to the perceived prima facieincompatibility between privileged self-knowledge and externalism. It argues that ifone conceives of linguistic action as voluntary behavior in a minimal sense, one cannot conceive ofbelief content to be externalistically constituted without simultaneously assuming that the agent hasknowledge of his beliefs. Accepting such a constitutive account of self-knowledge does not, however,preclude the conceptual possibility of being mistaken about one’s mental (...) states. Rather, self-knowledgehas to be seen as only a general constraint or as the default assumption of interpreting somebodyas a rational and intentional agent. This is compatible with the diagnosis of a localized lack of self-transparency. (shrink)

Brian Loar has argued that the well-known arguments against individualism in the philosophy of mind are insufficient because they rely on the assumption that that-clauses uniquely capture psychological content. He tried to show that this is not the use of that-clauses in philosophical psychology. I argue that he does not succeed in his argument. That-clauses sometimes capture psychological content, if our system of mental ascription is to be workable at all. I argue further that individualism tends to be at odds (...) with a requirement of intersubjective shareability of contents and that Loar is alternative conception of psychological content is beset with difficulties.

The author poses a question: when a person has a thought, what is it that determines what thought he is having? and, equivalently, what is it that determines what thought he is having. looking for an answer he sketches some general aspects of the problems involved in answering these questions, like the mind/body problem, for example. his conclusion is that the posed questions should be set against the background assumption that thoughts are just internal physical occurrences, and that thoughts are (...) categorized in the same way other mental occurrences are categorized. so the author categorizes them in terms of their introspectible characteristics and in terms of "that" clauses. these classifications can be understood as describing thought in terms of their place in the rational architecture.

I argue that our physical and social environments play a role in determining the content of most of our thoughts only indirectly—by playing a role in causing, and therefore, determining the content of, our reference-securing beliefs concerning general terms, beliefs that, when true, dictate what a general term will pick out. I also show that the problem of empty natural kind terms can be solved.

Proposed derivations of the Born rule for Everettian theory are controversial. I argue that they are unnecessary but may provide justification for a simplified version of the Principal Principle. It’s also unnecessary to replace Everett’s idea that a subject splits in measurement contexts with the idea that subjects have linear histories which partition Many worlds? Everett, quantum theory, and reality, Oxford University Press, Oxford, pp 181–205, 2010; Wallace in The emergent multiverse, Oxford University Press, Oxford, 2012, Chapter 7; Wilson in (...) Br J Philos Sci 64:709–737, 2013; The nature of contingency: quantum physics as modal realism, Oxford University Press, Oxford, forthcoming). Linear histories were introduced to provide a concept of pre-measurement uncertainty and I explain why pre-measurement uncertainty for splitting subjects is after all coherent, though not necessary because Everett’s original fission interpretation of branching can arguably be rendered coherent without it, via reference to Vaidman, Tappenden, Sebens and Carroll and McQueen and Vaidman. A deterministic and probabilistic quantum mechanics can be made intelligible by replacing the standard collapse postulate with a no-collapse postulate which identifies objective probability with relative branch weight, supplemented by the simplified Principal Principle and some revisionary metaphysics.

The first explicit argument for the incompatibility of externalism in the philosophy of mind and a priori self-knowledge is Boghossian’s discrimination argument. In this essay, I oppose the third premise of this argument, trying to show by means of a thought experiment that possessing the “twater thought” is not an alternative, a fortiori not a relevant alternative, to having the “water thought.” I then examine a modified version of Boghossian’s argument. The attempt is made to substantiate the claim that the (...) standard incompatibilist support for its second premise is untenable. Furthermore, a third Boghossian-style argument is rejected on the ground that either its second premise cannot be warranted in the way suggested by incompatibilists or its third premise is mistaken because having the “twater thought” instead of the “water thought” is not relevant. Finally, it is argued that the discrimination argument cannot be saved by invoking closure. The upshot of my discussion is that a compatibilist can dismiss Boghossian-style arguments for incompatibilism without having to deal with fundamental issues concerning self-knowledge and the nature of slow switching.

Some content externalists claim that if C is a theoretical concept and “C” expresses C, then the content of C in a community at a time is determined by how some members of the community at the time—call them “experts”—understand C or use “C”. Thus, when non-expert Chauncey utters “C”, the content of the concept he expresses does not depend entirely on his intrinsic physical properties, contra the claims of content internalism. This paper proposes that “concept” expresses a theoretical concept, (...) such that the externalist’s insights should apply to how we understand claims expressing the view itself and to how we evaluate the arguments alleged to motivate it. With respect to the first, I argue that the content externalist should regard it as unclear at present which proposition her theory expresses, and should take it that content externalism teaches us about our linguistic community rather than about the metaphysical nature of concepts. With respect to the second, I argue that by externalism’s own lights, the famous externalist thought experiments shouldn’t establish content externalism. In conclusion, I suggest that making sense of content externalism requires presupposing internalism. (shrink)

In recent years, two-dimensional (2D) semantics has been used to develop a broadly descriptivist approach to meaning that seeks to accommodate externalists’ counterexamples to traditional descriptivism. The 2D possible worlds framework can be used to capture a speaker’s implicit dispositions to identify the reference of her words on the basis of empirical information about her actual environment. Proponents of 2D semantics argue that this aspect of linguistic understanding plays the core theoretical role of meanings: 2D semantics allows us to specify (...) a reference-fixing criterion implicit mastery of which constitutes semantic competence a particular meaning.

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

To summarize, in order for rational agents to be able to engage in the sophisticated kinds of reasoning exemplified by human beings, they must be able to introspect much of their cognition. The problem of other minds and the problem of knowing the mental states of others will arise automatically for any rational agent that is able to introspect its own cognition. The most that a rational agent can reasonably believe about other rational agents is that they have rational architectures (...) similar to its own, and that they have thoughts related to their rational architectures in certain ways. This leads to Rational Functionalism as an account of what it is to be a cognizer having mental states. That in turn entails that a computer can be a person in precisely the same sense as my next door neighbor if it can appropriately mimic my rational architecture. There is nothing I could know about my neighbor that I could not believe with equal justification about the computer. Rational Functionalism also makes it reasonable to define the narrow content of a thought to be its overall place in the agent's rational architecture, that is, its conceptual role. This is, however, avery narrow notion of content. For practical purposes, we are not interested in knowing the narrow contents of other people's thoughts. We are only interested in rather general properties of those narrow contents. This is what is expressed by the use ofthat-clauses in public language. (shrink)

To illustrate the view that a speaker can have a partial understanding of a concept, Burge uses the example of Leibniz’s and Newton’s understanding of the concept of derivative. In a recent article, Sheldon Smith criticizes this example and maintains that Newton’s and Leibniz’s use of their derivative symbols does not univocally determine their references. The present article aims at challenging Smith’s analysis. It first shows that Smith misconstrues Burge’s position. It second suggests that the philosophical lessons one should draw (...) from the practice of the historians of philosophy are more ambivalent than what Smith thinks. (shrink)

ABSTRACT In recent debates about conceptual engineering, it appears that the internalist has an explanatory advantage when it comes to accounting for meaning change and conceptual change. In this paper, I argue against this impression. I show how two different varieties of externalism, originalism and anti-individualism, can coherently explain various cases of meaning change, irrespective of whether they involve proper names or kind terms; and also irrespective of whether they occur in everyday, legal, or scientific contexts. I point out which (...) mechanisms and interpretational strategies the originalist and anti-individualist can invoke, relative to their respective background assumptions about the nature of concepts. Furthermore, I offer an argument in favour of the claim that externalism as such has no implications concerning whether concepts can undergo change. I establish this by showing that originalism allows for conceptual change while anti-individualism insists on conceptual stability. (shrink)
