Medical assistance in dying, which includes voluntary euthanasia and assisted suicide, is legally permissible in a number of jurisdictions, including the Netherlands, Belgium, Switzerland and Canada. Although medical assistance in dying is most commonly provided for suffering associated with terminal somatic illness, some jurisdictions have also offered it for severe and irremediable psychiatric illness. Meanwhile, recent work in the philosophy of psychiatry has led to a renewed understanding of psychiatric illness that emphasises the role of the relation between the person (...) and the external environment in the constitution of mental disorder. In this paper, I argue that this externalist approach to mental disorder highlights an ethical challenge to the practice of medical assistance in dying for psychiatric illness. At the level of the clinical assessment, externalism draws attention to potential social and environmental interventions that might have otherwise been overlooked by the standard approach to mental disorder, which may confound the judgement that there is no further reasonable alternative that could alleviate the person’s suffering. At the level of the wider society, externalism underscores how social prejudices and structural barriers that contribute to psychiatric illness constrain the affordances available to people and result in them seeking medical assistance in dying when they otherwise might not have had under better social conditions.

The KK principle is typically rejected in externalist accounts of knowledge. However, a standard general argument for this rejection is in need of a supportive explication. In a recent paper, Samir Okasha argues that the standard externalist argument in question is fallacious. In this paper I start off with some critical discussion of Okasha’s analysis before suggesting an alternative way in which an externalist might successfully present such a case. I then further explore this issue via a (...) look at how Fred Dretske’s externalist epistemology, one of the exemplifying accounts, can explain failure of the KK principle. (shrink)

Several prominent philosophers have argued that the fact that depressed agents sometimes make moral judgments without being appropriately motivated supports Humean externalism – the view that moral motivation must be explained in terms of desires that are distinct from or “external” to an agent’s motivationally inert moral judgments. This essay argues that such motivational failures do not, in fact, provide evidence for this view. I argue that, if the externalist argument from depression is to undermine a philo-sophically important version (...) of internalism, it must make use of a general assumption about motivational states. However, at a reasonable level of abstraction, the needed assumption also implies that even desires could not be effective sources of motivation. For, just as depressed agents might sometimes lack motivation to act consistently with their moral judgments, they also sometimes lack motivation to pursue their desires. Moreover, the most plausible responses that Humeans can give to this general argument undermine the externalist case against internalism. Thus, there is a deep tension between the argument from depression for externalism and a fundamental Humean commitment. (shrink)

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) even granting (...) (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

Whereas a number of recent articles have focussed upon whether the thesis of content externalism is compatible with a certain sort of knowledge that is gained via first-person authority,1 far less attention has been given to the relationship that this thesis bears to the possession of knowledge in general and, in particular, its relation to internalist and externalist epistemologies. Nevertheless, although very few actual arguments have been presented to this end, there does seem to be a shared suspicion (...) that content externalism must be incompatible with epistemic internalism. In a recent and influential paper, however, James Chase has challenged this conventional wisdom by offering a subtle defence of the view that content externalism and epistemic internalism are, in fact, compatible after all.2 Our aim here is twofold. First, to show that Chase is only able to achieve this result because he focuses upon the internalist conception of justification, rather than knowledge. Second, to formulate one prima facie argument which shows that an internalist conception of knowledge is incompatible with an externalist conception of content, an argument which, moreover, is not touched by Chase.

Abstract I first suggest some ways in which the externalist account of psychological content can be reconciled with the aspectual character of intentionality. I then give an argument against the externalist account which includes as premises the claims that a system capable of having intentional states must understand a language, and that a system that understands a language must be capable of consciousness. I defend the latter claim by arguing that a correct understanding of observation sentences requires conscious, (...) sensory experience, and by appealing to the fact that language has meaning in a holistic manner.

I highlight a neglected but striking phenomenological fact about our experiences: they have a pervasively spatial character. Specifically, all (or almost all) phenomenal qualities – roughly, the introspectible, philosophically puzzling properties that constitute ‘what it’s like’ to have an experience – introspectively seem instantiated in some kind of space. So, assuming a very weak charity principle about introspection, some phenomenal qualities are instantiated in space. But there is only one kind of space – the ordinary space occupied by familiar objects. (...) And the only objects appropriately located in ordinary space are outside the subject’s mind. This entails experiential externalism, the view that at least one phenomenal quality is instantiated outside the subject’s mind. Experiential externalism is incompatible with many leading theories of experience, including certain mental paint theories; some forms of representationalism; paradigmatic versions of sense-datum theory; and views on which no phenomenal qualities are instantiated. My argument is structurally similar to familiar arguments based on the ‘transparency of experience.’ However, I suggest, phenomenological intuitions about spatiality are considerably more stable than phenomenological intuitions about transparency. For many philosophers, transparency intuitions fade markedly with respect to non-standard experiences, including experiences associated with blurry or double vision. But spatiality intuitions remain robust even for these experiences. Thus, spatiality intuitions should be more dialectically effective than transparency intuitions for supporting experiential externalism. (shrink)

Juhani Yli-Vakkuri has argued that the Twin Earth thought experiments offered in favour of semantic externalism can be replaced by a straightforward deductive argument from premisses widely accepted by both internalists and externalists alike. The deductive argument depends, however, on premisses that, on standard formulations of internalism, cannot be satisfied by a single belief simultaneously. It does not therefore, constitute a proof of externalism. The aim of this article is to explain why.

심적 내용에 대한 외재주의가 등장한 이래로 이런 종류의 입장이 사고에 대한 일인칭적 특권적 접근과 양립가능한지 여부가 문제시되어왔다. 맥킨지는 오랫동안 양립불가능성을 옹호해왔으며, 우리가 특권적 접근을 포기해야 한다고 논증한다. 이에 대항하여 브뤼크너는 맥킨지의 논증이 실패한다고 반론하며 양립가능성을 옹호한다. 그러나 브뤼크너의 비판에는 몇 가지 중요한 문제점이 있다. 특히 브뤼크너가 받아들이는 특권적 접근은 맥킨지의 결론과 사실상 충돌하지 않는다.

Psychological externalism is the thesis that the contents of many of a person's propositional mental states are determined in part by relations he bears to his natural and social environment. This thesis has recently been thrust into prominence in the philosophy of mind by a series of thought experiments due to Hilary Putnam and Tyler Burge. Externalism is a metaphysical thesis, but in this work I investigate its implications for the epistemology of the mental. I am primarily concerned with the (...) question whether externalism undermines the idea that a person typically knows the contents of her own thoughts, beliefs, and other propositional attitudes directly and authoritatively. I criticize arguments that have been advanced on behalf of a positive answer to this question, and argue that they rest on a faulty conception of the nature of first person authority, one which likens our access to our own minds to perception. An account of the basis of first person authority is sketched that locates our epistemic right to our self-ascriptions of propositional attitude not in our ability to discriminate among the various thought contents we might be thinking, but rather in our ability to express our thoughts, and to think with them in accordance with the norms of rationality. I consider also the question whether first person authority and externalism jointly make possible a refutation of certain forms of global skepticism, as has been famously argued by Putnam. I argue that Putnam's attempted refutation fails, because the crucial externalist claims that drive it are not knowable a priori. (shrink)

Feldman and Conee (2001) observed that the term “internalism”, as used in epistemology, is ambiguous. It sometimes denotes the view that justification supervenes on factors within the thinker (“mentalism”), whereas at other times it refers to the view that justification is accessible to the thinker (“accessibilism”). As used in the debate about mental content, “internalism” corresponds to mentalism. Strikingly, however, it is the question of accessibilism that is the target of many internalist and externalist arguments. In this paper (...) I argue that the focus on thinkers’ access to their thoughts is misplaced. The debate between externalism and internalism hinges on the significance of external factors for rational relations between first-order thoughts, not on issues of accessibility. The shift away from issues of accessibility neutralizes both the “incompatibility” objection to externalism and the charge that internalism overestimates first-person access. The revised understanding of the debate supports a broadly Fregean approach to individuating cognitive values. I develop a version of this approach and defend it from a prominent externalist objection. Since this approach individuates cognitive values narrowly, my argument ultimately supports internalism. (shrink)

The aim of this paper is to show that the truth of content externalism can be grounded in purely epistemological considerations in which no appeal is made to Twin‐Earth style cases. Content externalism is required to provide an adequate account of perceptual warrant.

I claim that there are four major strands of argument for externalism and set out to discuss three of them. The four are: (A) That referential thoughts are object-dependent. This I do not discuss. (B) That the semantics of natural kind terms is externalist. (C) That all semantic content, even of descriptive terms, stems from the causal relations of representations to the things or properties they designate in the external world. (D) That, because meaning is a social product and (...) no individual can capture the whole social practice that defines a concept, what the speaker means always outruns what he can know.I briefiy discuss (C) and (D) and conclude that they cannot be correct, because, if they were, the content of every thought would permanently transcend the refiective grasp of all thinkers. Then I discuss (B) and conclude that, though Putnam shows something interesting about natural kind terms -- namely that a real verbal definition requires science -- this has none of the consequences for philosophy of mind that it is normally supposed to have. (shrink)

Several lines of reasoning have been proposed to show the incompatibility of content externalism with justification internalism. In this paper I examine two such lines of reasoning, which both rely on the general idea that since content externalism is incompatible with certain aspects of the alleged privileged character of self-knowledge, it would tend to undermine justification internalism as well. I shall argue that both lines of reasoning, as they stand, lack plausibility, though the core idea of the second line can (...) be reconstructed into a new argument which shows considerable promise. In particular, relying upon the reliability constraint on knowledge, I shall argue that the so-called ‘two-concept’ version of content externalism is incompatible with ‘the transparency of sameness of content’, and thereby would also undermine justification internalism. (shrink)

In his fetishist argument, Michael Smith raises an important question: What is the content of the motivational states that constitute moral motivation? Although the argument has been widely discussed, this question has not received the attention it deserves. In the present paper, I use Smith’s argument as a point of departure for a discussion of how advocates of externalism as regards moral judgements can account for moral motivation. More precisely, I explore various explanations of moral motivation that externalists can employ (...) to answer the question Smith poses. (shrink)

SummaryA familiar sort of argument for skepticism about the external world appeals to the evidential similarity between what is presumed to be the normal case and the case where one is a brain in a vat . An argument from Putnam has been taken by many to provide an a priori refutation of this sort of skeptical argument. The question I propose to address in this paper is whether Putnam's argument affords us an a priori refutation of skeptical arguments (...) that appeal to the claim that one does not know that one is not a BIV. I will develop a negative answer to this question along two related fronts. Along the first front I defend against new criticisms the common position that the externalism on which Putnam's argument is based entails skepticism about the meanings of sentences in our language and the contents of our thoughts. I do not take this to be a refutation of externalism or externalist arguments; rather, I see this as a motivation to locate the difficulty with arguments for externalism. But if externalism is abandoned, of course, the anti‐skeptical argument it has widely been taken to support must be abandoned along with it. I will argue, however, that this is not a significant loss, because along a second front I will argue that externalism cannot be given a priori justification; it is therefore ill‐suited to ground an a priori refutation of BIV skepticism anyway.

It is argued that the knowledge argument fails against externalist theories of mind. Enclosing Mary and cutting her off from some properties denies part of the physical world to Mary, which has the consequence of denying her certain kinds of physical knowledge. The externalist formulation of experience is shown to differ in vehicle, content, and causal role from the internalist version addressed by the knowledge argument, and is supported by results from neuroscience. This means that though the knowledge (...) argument has some force against material internalists, it misses the mark entirely against externalist accounts. (shrink)

Externalism is the thesis that the contents of intentional states and speech acts are not determined by the way the subjects of those states or acts are internally. It is a widely accepted but not entirely uncontroversial thesis. Among such theses in philosophy, externalism is notable for owing the assent it commands almost entirely to thought experiments, especially to variants of Hilary Putnam's famous Twin Earth scenario. This paper presents a thought experiment-free argument for externalism. It shows that externalism is (...) a deductive consequence of a pair of widely accepted principles whose relevance to the issue has hitherto gone unnoticed. (shrink)

Paul Boghossian has put forward an influential argument against Tyler Burge's account of basic self‐knowledge. The argument focuses on the relation between externalism about mental content and memory. In this paper, I attempt to analyze and answer Boghossian's argument.

I deal here with one of Boghossian’s arguments against content externalism, related to ourinferential rationality(to use his term). According to his reasoning, the apriority of our logical abilities is inconsistent with certain externalist assumptions. Nevertheless, the problem constitutes an important challenge foranytheory of content, not just for externalism. Furthermore, when we examine what internalists may propose to solve the problem, we see that externalists have at their disposal a more promising repertoire of possible replies than internalists. In that (...) sense, insofar as Boghossian’s scenario is relevant to the debate externalism/internalism, it can be seen (against Boghossian’s original intention) as providing additional evidence for content externalism. (shrink)

Recent discussions of externalism about mental content have been dominated by the question whether it undermines the intuitively plausible idea that we have knowledge of the contents of our thoughts. In this article I focus on one main line of reasoning (the so-called 'slow switching argument') for the thesis that externalism and self-knowledge are incompatible. After criticizing a number of influential responses to the argument, I set out to explain why it fails. It will be claimed that the argument trades (...) on an ambiguity, and that only by incorporating certain controversial assumptions does it stand a chance of establishing its conclusion. Finally, drawing on an analogy with Benacerraf's challenge to Platonism, I shall offer some reasons as to why the slow switching argument fails to reveal the real source of tension between externalism and privileged self-knowledge.

Temporal externalism (TE) is the thesis (defended by Jackman (1999)) that the contents of some of an individual’s thoughts and utterances at time t may be determined by linguistic developments subsequent to t. TE has received little discussion so far, Brown 2000 and Stoneham 2002 being exceptions. I defend TE by arguing that it solves several related problems concerning the extension of natural kind terms in scientifically ignorant communities. Gary Ebbs (2000) argues that no theory can reconcile our ordinary, practical (...) judgments of sameness of extension over time with the claim that linguistic usage determines word extensions. I argue that Ebbs shows at most that no theory other than TE can effect this reconciliation. Furthermore, while Ebbs’ argument undermines Jessica Brown’s solutions to two closely related problems about natural kind term extensions (Brown 1998), TE can solve both problems without difficulty. Some criticisms of TE are briefly addressed as well. (shrink)

Externalism about colour phenomenology claims that the phenomenal character of colour experiences is determined by mind-independent properties of perceptual objects. The structural mismatch argument shows that physical properties of perceived mind-independent things are not similar in ways that correlate with the ways in which the phenomenal character of colour experiences are similar. Structural mismatch has thus been perceived by some to demonstrate that correlative externalism (which takes mind-independent physical properties to correlate systematically with colour phenomenology) is false. This argument is (...) defused if there are broad physical properties that can bear similarity relations that do correlate with those held by the phenomenal character of colour experiences. I defend the view that disjunctive properties can perform this role by showing that disjunctive properties can account for metamerism, the unique and binary hue distinction, and differences in perceived colours between subjects. Finally, I argue that correlative externalism is better placed than other views to explain why the physical properties identified by the physical sciences correlate with colour experiences with the particular phenomenal character they have.

Some worry that semantic externalism is incompatible with knowing by introspection what content your thoughts have. In this paper, I examine one primary argument for this incompatibilist worry, the slow-switch argument. Following Goldberg , I construe the argument as attacking the conjunction of externalism and “skeptic immune” knowledge of content, where such knowledge would persist in a skeptical context. Goldberg, following Burge :649–663, 1988), attempts to reclaim such knowledge for the externalist; however, I contend that all Burge-style accounts vindicate (...) that a subject can introspectively know that she is thinking that “water is wet.” They do not yet show how a subject can introspectively know what she is thinking—which is the distinctive type of knowing at issue in the slow-switch argument. Nonetheless, I subsequently amend the Burge-style view to illustrate how an externalist can introspectively “know-what” content her thought has, and know it in a skeptic immune manner, despite what the slow-switch argument may suggest. For one, I emphasize that “knowing what” can be ontologically non-committal . For another, following Boer and Lycan , I stress that “knowing what” is purpose-relative–and for at least some purposes, it seems possible for the externalist to “know what” content her thought has, even if skeptical hypotheses about XYZ are relevant.

Externalism in the philosophy of mind has been invoked by some philosophers to argue that content‐bearing mental states can’t serve as the explananda in genuinely causal explanations of behaviour. In this paper, I demonstrate that such arguments presuppose that psychological explanations are theory‐based and that, if this theoretical conception of psychological explanation is replaced by the simulation model, we remove the source of the apparent tension between externalism and caus‐ality and are in a position to understand how appeal to (...) content‐bearing mental states may be causally explanatory.

According to Bayesian orthodoxy, an agent should update---or at least should plan to update---her credences by conditionalization. Some have defended this claim by means of a diachronic Dutch book argument. They say: an agent who does not plan to update her credences by conditionalization is vulnerable (by her own lights) to a diachronic Dutch book, i.e., a sequence of bets which, when accepted, guarantee loss of utility. Here, I show that this argument is in tension with evidence externalism, i.e., the (...) view that an agent's evidence can entail non-trivial propositions about the external world. I argue that this tension casts doubt on the idea that diachronic Dutch books can be used to justify or vindicate updating plans. (shrink)

I criticize some armchair arguments against phenomenal externalism due to Block, Hawthorne, Kriegel, Levine, Shoemaker and others. I conclude by discussing an overlooked armchair argument: the argument from phenomenal localism.

Section 1 of the paper reviews a family of “no good inference” arguments for skepticism about the external world, and a straightforward externalist reply. Section 2 reviews skeptical regress arguments, and another straightforward reply. Section 3 considers three objections to foundationalism that are inspired by Sellars’ critique of “the given” in “Empiricism and the Philosophy of Mind,” and argues that none of these is effective against the kind of “externalist foundationalism” defended in Sects. 1 and 2.

Joseph Mendola argues that internalism is true, and that there are no good arguments that support externalism. Anti-Externalism has three parts.

The argument known as the 'McKinsey Recipe' tries to establish the incompatibility of semantic externalism (about natural kind concepts in particular) and _a priori _self- knowledge about thoughts and concepts by deriving from the conjunction of these theses an absurd conclusion, such as that we could know _a priori _that water exists. One reply to this argument is to distinguish two different readings of 'natural kind concept': (i) a concept which _in fact _denotes a natural kind, and (ii) a concept (...) which _aims_ to denote a natural kind. Paul Boghossian has argued, using a _Dry Earth _scenario, that this response fails, claiming that the externalist cannot make sense of a concept aiming, but failing, to denote a natural kind. In this paper I argue that Boghossian's argument is flawed. Borrowing machinery from two-dimensional semantics, using the notion of 'considering a possible world as actual', I claim that we can give a determinate answer to Boghossian's question: which concept would 'water' express on Dry Earth?

ABSTRACTHilary Putnam provides an anti-skeptical argument motivated by semantic externalism. He argues that our best theorizing about what it takes to experience, think, and so on, entails that the world is much as we take it to be. This fact eliminates the possibility of radical skeptical scenarios, where from our perspective everything seems as it does in the actual case, but we are widely and systematically mistaken. I think that this approach is generally correct, and that it is the most (...) promising strategy for undermining radical skepticism. There are, however, well-discussed difficulties with Putnam's way of pursuing this strategy. I argue that in order to avoid these objections we will have to be more radical externalists than Putnam proposed; in particular, we will have to beperspectival externalists. According to perspectival externalism, a subject's reliable relations to her environment play a crucial role in determining not only the contents of her mental events, but also what it is like for her to grasp those contents. While semantic externalism is widely accepted in epistemology, perspectival externalism is not. I argue that perspectival externalism is independently more plausible than mere semantic externalism, and that such an account can enable us to better pursue Putnam's anti-skeptical strategy.

According to an externalist theory of content the content of an individual’s thoughts and the meaning of her words need not supervene on her intrinsic history. Two individuals may be intrinsically exactly alike yet entertain different thoughts, and attach different meanings to the words they use. ETC, which has been most notably defended by Saul Kripke, Hilary Putnam and Tyler Burge, has attained the status of current orthodoxy. Nevertheless, some maintain that combining ETC with the premisses that we have (...) privileged access to our intentional states yields a surprising conclusion. It yields the conclusion that we can have a priori knowledge of features of the external world that seem only accessible to empirical investigation. Call the argument from ETC and privileged access to this conclusion the main argument. Some take the main argument to be a reductio of ETC. Since we have privileged access to our intentional states, and lack the a priori knowledge attributed by the main argument, ETC is false. Some take the main argument to refute the premisses that we have privileged access to those intentional states falling within the scope of ETC. Others see the main argument as a refutation of external world scepticism. We will show that the main argument does not support any of these interesting conclusions. We will show that the main argument does not threaten to restrict privileged access, refute external world scepticism, or constitute a reductio of ETC. More exactly, we will show that the most defensible version of ETC, even when combined with the premiss that we have unrestricted privileged access to our intentional states, yields no a priori knowledge of the external world.

According to externalism, reference is a relation between uses of an expression and features of the environment. Moreover, the reference relation is normative , and the referential relata of our expressions are explanatory of successful language use. This paper largely agrees with the broad conception underlying externalism: it is what people do with words that makes them have the references they have, and the world constrains what people can successfully do with words. However, the paper strongly disagrees with the details (...) . A centrally important feature of what people do with words is how they use them in inferential contexts. When due attention is given to the reference-determining role played by inferential properties of expressions, I argue, we arrive at a more satisfactory account of semantic norms and explanations. Much of the argument is based on a detailed look at the language of chemical classification used in the late 19th century. (shrink)

Semantic externalism is the view that the meanings of referring terms, and the contents of beliefs that are expressed by those terms, are not fully determined by factors internal to the speaker but are instead bound up with the environment. The debate about semantic externalism is one of the most important but difficult topics in philosophy of mind and language, and has consequences for our understanding of the role of social institutions and the physical environment in constituting language and the (...) mind. In this long-needed book, Jesper Kallestrup provides an invaluable map of the problem. Beginning with a thorough introduction to the theories of descriptivism and referentialism and the work of Frege and Kripke, Kallestrup moves on to analyse Putnam’s Twin Earth argument, Burge’s arthritis argument and Davidson’s Swampman argument. He also discusses how semantic externalism is at the heart of important topics such as indexical thoughts, epistemological skepticism, self-knowledge, and mental causation. Including chapter summaries, a glossary of terms, and an annotated guide to further reading, _Semantic Externalism_ an ideal guide for students studying philosophy of language and philosophy of mind.

This paper argues for externalism about justification on the basis of thought experiments. I present cases in which two individuals are intrinsically and introspectively indistinguishable and in which intuitively, one is justified in believing that p while the other is not. I also examine an argument for internalism based on the ideas that we have privileged access to whether or not our own beliefs are justified and that only internalism is compatible with this privilege. I isolate what I take to (...) be the most plausible form of privileged access to justification and show that it is compatible with externalism. (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)

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)

Consider the Evidence Question: When and under what conditions is proposition P evidence for some agent S? Silins (Philos Perspect 19:375–404, 2005) has recently offered a partial answer to the Evidence Question. In particular, Silins argues for Evidential Internalism (EI), which holds that necessarily, if A and B are internal twins, then A and B have the same evidence. In this paper I consider Silins’s argument, and offer two response on behalf of Evidential Externalism (EE), which is the denial of (...) Evidential Internalism. The first response claims that the allegedly unattractive consequence for EE is not so unattractive. The second response takes the form of a tu quoque, demonstrating that a structurally similar argument can be constructed against EI. The two responses play off one another: objecting to the first puts pressure on one to accept the other. Taken together, the two responses have important ramifications for how we answer the Evidence Question, and how we think about evidence in general. (shrink)

Putnam and Burge have been viewed as launching a joint attack on individualism, the view that the content of one's psychological state is determined by what is in the head . Putnam argues that meanings are not in the head while Burge argues that beliefs are not in the head either, and both have come up with convincing arguments against individualism. It is generally conceived that Putnam's view is a version of physical externalism, which argues that factors in the (...) physical environment play a role in determining the meanings of natural kind terms. Burge, on the other hand, is regarded as following up Putnam's argument to bring in factors in the social environment for the determination of belief. Burge's view has been commonly referred to as 'social externalism.' The general consensus in the field is that physical externalism and social externalism are compatible views. Furthermore, both Putnam and Burge seem to endorse each other’s position for the most part. In this paper, however, I shall argue against this general view to show that the two theories are deep down incompatible. (shrink)

The argument that has inspired much of the recent discussion of the logical relationship between these views is found in Putnam : If externalism is true, then if S were a brain in a vat, S’s utterances of the sentence “I am a brain in a vat” would not express the proposition that S is a brain in a vat. S’s use of the words “brain” and “vat” would not refer to a real brain or vat, just as, in a (...) Twin Earth-style thought experiment, the Twin Earthling cannot refer to water with his use of the term “water.” If we accept that generally we have knowledge of the contents of our utterances, then, if S knows that her utterances of “brain” and “vat” mean brain and vat, it will be possible for S to know that she is not a brain in a vat. For if S has authority with respect to the contents of her utterances, then she can know that her utterance, “I am not a brain in a vat,” refers to brains and vats. On externalism, since S would not refer to brains and vats if she were a brain in a vat, she could know by mere introspection that she is not a brain in a vat. In fact, S can come to know many arbitrary propositions about the external world simply by attending to the contents of her thoughts. For if externalism is true, she can argue, then certain empirical conditions must be satisfied if she is even to have the thoughts about the external world that she does; since she knows what she is thinking, she knows these empirical conditions are satisfied. Thus, if S knows that she is thinking about brains and vats, then she can know that she is not a brain in a vat ; for if she was a BIV, then she would not be thinking about brains and vats, but instead about electrical impulses or some such thing. The standard BIV argument against scepticism, therefore, cannot be correct. This line of argument can then be used to conclude more generally that scepticism is false; for the argument can be run with virtually any utterance or thought with empirical content. If S knows that she is thinking about trees, for example, then she can know that there are trees. (shrink)

Yli-Vakkuri offers a deductive argument for Content Externalism that primarily appeals to two main principles he says should be adopted by all parties to the debate. Sawyer criticizes this argument on the grounds that there are internalist theories that are not consistent with the two principles he offers, although she takes no issue with the derivation itself. While Sawyer’s critique is insightful and largely correct, there is a more fundamental problem with the original argument. The formal proof given in the (...) original paper begs the question. The informal argument is enthymematic, and all the possible valid reconstructions require assumptions that can be legitimately rejected by content internalists. This is significant to point out as someone might think that the internalist views that Sawyer says are not consistent with the two principles that drive Yli-Vakkuri’s argument can be successfully challenged and thereby the original argument defended.

This paper examines the relationship between the KK principle and the epistemological theses of externalism and internalism. In particular we examine arguments from Okasha :80–86, 2013) and Greco :169–197, 2014) which deny that we can derive the denial of the KK principle from externalism.

Phenomenal intentionality is a singular form of intentionality. Science shows it is internally-determined. So standard externalist models for reducing intentionality don't apply to it.
