Ever since the 1970’s, philosophers of mind have engaged in a lively discussion of Externalism. Externalism is the metaphysical thesis that the contents of one’s thoughts are determined partly by empirical features of one’s environment. Externalism appears to clash with another plausible thesis—the epistemological thesis that one can have knowledge of one’s own thoughts, without evidence or empirical investigation. Many have argued that the conjunction of these theses is incompatible. I have argued elsewhere for their compatibility.1 Here I’ll just assume (...) that they are compatible and explore some consequences of conjoining a particular externalist thesis about the contents of thoughts (Social Externalism) with a particular thesis about self-knowledge (First-Person Authority). (shrink)

Social Externalism is the thesis that many of our thoughts are individuated in part by the linguistic and social practices of the thinker’s community. After defending Social Externalism and arguing for its broad application, I turn to the kind of defeasible first-person authority that we have over our own thoughts. Then, I present and refute an argument that uses first-person authority to disprove Social Externalism. Finally, I argue briefly that Social Externalism—far from being incompatible with first-person authority—provides a check on (...) first-personal pronouncements and thus saves first-person authority from being simply a matter of social convention and from collapsing into the subjectivity of “what seems right is right.”.

Traditionally, Anglophone philosophers have assumed that the identity of a thought is determined wholly by the subject's intrinsic states--e.g., her brain states. In the 1970's, this traditional view (lately called 'individualism' or ‘internalism’) was challenged by Hilary Putnam and Tyler Burge, who argued that the contents of one’s beliefs, desires, intentions are partly determined by one's physical, social and/or linguistic environment. The question is not whether the environment causes one to think what one does. Rather, the question is one of (...) the identity of thoughts: In virtue of what is a thought the particular thought that it is? According to Putnam and Burge, the answer lies partly in the environment. What makes the belief expressed by ‘water is wet’ the belief that it is depends on the presence of H2O in the environment, not just on the believer’s internal states. The view that thoughts are individuated in part by environmental factors has come to be called ‘anti-individualism’ or ‘externalism’. (shrink)

Abstract: For quite some time now there has been an ongoing debate whether authoritative self-knowledge is compatible with anti-individualism.1 One influential line of argument against compatibilism is due to Paul Boghossian (1998). I argue that Boghossian misconstrues what the anti-individualist really is committed to. This defence of compatibilism is elaborated by showing how the Twin Earth thought experiment is meant to speak in favour of anti-individualism. Partly this will show that Boghossian is wrong in his denial that empirical background knowledge (...) is imported into the Twin Earth experiment. The main points argued are that Boghossian fails to realize, both, (1) that anti-individualism does not involve concept-individuation in terms of reference, and (2) that anti-individualism assumes a core of representational success. In effect, these two points constitute an entirely new way to defend compatibilism, a way that seems to have gone unnoticed in the literature. (shrink)

This paper criticizes the widespread view whereby a second-order judgment of the form ‘I believe that p ’ qualifies as self-knowledge only if the embedded content, p , is of the same type as the content of the intentional state reflected upon and the self-ascribed attitude, belief, is of the same type as the attitude the subject takes towards p . Rather than requiring identity of contents across levels of cognition self-knowledge requires only that the embedded content of the second-order (...) thought be an entailment of the content of the intentional state reflected upon. And rather than demanding identity of attitudes across levels of cognition self-knowledge demands only that the attitude of the intentional state reflected upon and the attitude the subject self-attributes share certain features such as direction of fit and polarity.

This paper argues that Sosa’s virtue perspectivism fails to combine satisfactorily internalist and externalist features in a single theory. Internalism and externalism are reconciled at the price of creating a Gettier problem at the level of “reflective” or second-order knowledge. The general lesson to be learned from the critique of virtue perspectivism is that internalism and externalism cannot be combined by bifurcating justification and knowledge into an object-level and a meta-level and assigning externalism and internalism to different levels.

Content externalism about memory says that the individuation of memory contents depends on relations the subject bears to his past environment. I defend externalism about memory by arguing that neither philosophical nor psychological considerations stand in the way of accepting the context dependency of memory that follows from externalism.

This paper addresses the question whetherintrospection plus externalism about mental contentwarrant an a priori refutation of external-worldskepticism and ontological solipsism. The suggestionis that if thought content is partly determined byaffairs in the environment and if we can havenon-empirical knowledge of our current thoughtcontents, we can, just by reflection, know about theworld around us – we can know that our environment ispopulated with content-determining entities. Afterexamining this type of transcendental argument anddiscussing various objections found in the literature,I argue that the notion (...) of privileged self-knowledgeunderlying this argument presupposes that we canlearn, via introspection, that our so-called thoughtsare propositional attitudes rather than contentlessstates. If, however, externalism is correct andthought content consists in the systematic dependencyof internal states on relational properties, we cannotknow non-empirically whether or not we havepropositional attitudes. Self-knowledge (apropositional attitude) is consistent with us lackingthe ability to rule out, via introspection, thepossibility that we don't have any propositionalattitudes. Self-knowledge provides us with knowledgeof what is in our minds, but not that we haveminds. Hence, the combination of externalism with thedoctrine of privileged self-knowledge does not allowfor an a priori refutation of skepticism and istherefore unproblematic. (shrink)

Incompatibilism is the view that privileged knowledge of our own mental states cannot be reconciled with externalism regarding the content of mental states. Davidson has recently developed two arguments that are supposed to disprove incompatibilism and establish the consistency of privileged access and externalism. One argument criticizes incompatibilism for assuming that externalism conflicts with the mind?body identity theory. Since mental states supervene on neurological events, Davidson argues, they are partly ?in the head? and are knowable just by reflection. Another argument (...) rejects incompatibilism by repudiating the object perception model of introspection. Once extemalism is freed from the internalist idea that thoughts take objects which are inner epistemological intermediaries, Davidson maintains, it poses no threat to privileged self?knowledge. It is argued that neither of these arguments is successful, since both disprove assumptions irrelevant to incompatibilism. Moreover, it is indicated how Davidson would have to go about defending his positive account of privileged self?knowledge against the principal incompatibilist arguments. (shrink)

Controversy continues to attach to the question whether an externalism about mental content is compatible with a traditional doctrine of privileged self-knowledge. By an externalism about mental content, I mean the view that what concepts our thoughts involve may depend not only on facts that are internal to us, but on facts about our environment. It is worth emphasizing, if only because it is still occasionally misperceived, that this thesis is supposed to apply at the level of sense and not (...) merely at that of reference: what concepts we think in terms of -- and not just what they happen to pick out -- is said by the externalist to depend upon environmental facts. By a traditional doctrine of privileged self-knowledge, I mean the view that we are able to know, without the benefit of empirical investigation, what our thoughts are in our own case. Suppose I entertain a thought that I would express with the sentence `Water is wet'. According to the traditional doctrine, I can know without empirical investigation (a) that I am entertaining a thought; (b) that it has a particular conceptual content, and (c) that its content is that water is wet.

Externalism is the view that some crucial element in the content of our representational states is outside of not just the states whose content they are but even the person who has those states. If so, the contents of such states (and, many hold, the states themselves) do not supervene on anything local to the person whose has them. There are a number of different candidates for what that element is: function (Dretske), causal connection (Putnam, Kripke, Fodor), and social context (...) (Davidson). (Burge has foot in both the causal connection and the social context camps and Dennett fits in here somewhere, too.) This diversity will turn out to be important. The paper starts with Dretske but gets to other varieties of. (shrink)

I consider whether one particular anti-individualist claim, the doctrine of object-dependent thoughts (DODT), is compatible with the Principle of Privileged Access, or PPA, which states that, in general, a subject can have non-empirical knowledge of her thought contents. The standard defence of the compatibility of anti-individualism and PPA emphasises the reliability of the process which produces a subject's second order beliefs about her thought contents. I examine whether this defence can be applied to DODT, given that DODT generates the possibility (...) of illusions of thought. Drawing on general epistemological literature, I distinguish several senses of reliability, and argue that in the relevant sense-'global reliability'-DODT does sometimes threaten reliability and hence PPA. (shrink)

Following Burge, many anti-individualists suppose that a subject can possess a concept even if she incompletely understands it. While agreeing that this is possible, I argue that there is a limit on the extent to which a subject can incompletely understand the set of concepts she thinks with. This limit derives from our conception of our ability to reflectively evaluate our own thoughts or, as Burge puts it, our ability to engage in critical reasoning. The paper extends Burge's own work (...) on critical reasoning. He argued that critical reasoning imposes a limit on the extent to which we can be mistaken about what thoughts we are having; in general, we can know non-empirically what we are thinking (Burge, "Our Entitlement to Self-Knowledge", Proceedings of the Aristotelian Society XCVI, 1996). He does not explicitly consider whether critical reasoning also imposes a limit on incomplete understanding of thoughts. (shrink)

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.

In "Externalism, Self-Knowledge and Skepticism,"' Kevin Falvey and Joseph Owens argue that externalism with respect to mental content does not engender skepticism about knowledge of content. They go on to argue that even when externalism is freed from epistemological difficulties, the thesis cannot be used against Cartesian skepticism about knowledge of the external world. I would like to raise some questions about these claims.

Externalism holds, and internalism denies, that the individuation of many of an individual's mental states (e.g., thoughts about the physical world) depends necessarily on relations that individual bears to the physical and/or social environment. Many philosophers, externalists and internalists alike, believe that introspection yields knowledge of the contents of our thoughts that is direct and authoritative. It is not obvious, however, that the metaphysical claims of externalism are compatible with this epistemological thesis. Some (e.g., Burge, 1988; Falvey and Owens (F&O), (...) 1994) have sought to dispel the worry that there is a conflict, though they admit that if such a conflict exists, it spells trouble for externalism (see, e.g., F&O, 1994, p. 108). Boghossian has argued that there is indeed a conflict between externalism and introspective knowledge of content. Surprisingly, however, he also argues that there is a conflict between internalism and introspective knowledge of content. I will defend Boghossian's claim that there is a conflict between externalism and knowledge of content, but criticize his claim that there is a conflict between internalism and knowledge of content. (shrink)

Most content externalists concede that even if externalism is compatible with the thesis that one has authoritative self-knowledge of thought contents, it is incompatible with the stronger claim that one is always able to tell by introspection whether two of one’s thought tokens have the same, or different, content. If one lacks such authoritative discriminative self-knowledge of thought contents, it would seem that brute logical error – non-culpable logical error – is possible. Some philosophers, such as Paul Boghossian, have argued (...) that this would present a big problem for externalism, forcing the externalist to overhaul our norms of rationality. I consider several externalist strategies to block this possibly unhappy epistemological consequence, but I argue that they all fail. (shrink)

By exploiting a concept called ways of believing, I offer a plausible reformulation of the doctrine of privileged access. This reformulation will provide us with a defense of compatibilism, the view that content externalism and privileged access are compatible.

[I]f you could know a priori that you are in a given mental state, and your being in that state conceptually or logically implies the existence of external objects, then you could know a priori that the external world exists. Since you obviously _can.

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. (shrink)

In previous work I argued that skepticism about the compatibility ofanti-individualism with self-knowledge is incoherent. Anthony Brueckner isnot convinced by my argument, for reasons he has recently explained inprint. One premise in Brueckner's reasoning is that a person'sself-knowledge is confined to what she can derive solely from herfirst-person experiences of using her sentences. I argue that Brueckner'sacceptance of this premise undermines another part of his reasoning – hisattempt to justify his claims about what thoughts our sincere utterances ofcertain sentences would (...) express in various possible worlds. I describe aweird possible world in which a person who uses Brueckner's reasoning endsup with false beliefs about what thoughts her sincere utterances of certainsentences would express in various possible worlds. I recommend that wereject Brueckner's problematic conception of self-knowledge, and adopt onethat better fits the way we actually ascribe self-knowledge. (shrink)

A central question in contemporary epistemology concerns whether content externalism threatens a common doctrine about privileged access. If the contents of a subject.

Descartes's philosophy has had a considerable influence on the modern conception of the mind, but many think that this influence has been largely negative. The main project of The Subject's Point of View is to argue that discarding certain elements of the Cartesian conception would be much more difficult than critics seem to allow, since it is tied to our understanding of basic notions, including the criteria for what makes someone a person, or one of us. The crucial feature of (...) the Cartesian view defended here is not dualism--which is not adopted--but internalism. Internalism is opposed to the widely accepted externalist thesis, which states that some mental features constitutively depend on certain features of our physical and social environment. In contrast, this book defends the minority internalist view, which holds that the mind is autonomous, and though it is obviously affected by the environment, this influence is merely contingent and does not delimit what is thinkable in principle. Defenders of the externalist view often present their theory as the most thoroughgoing criticism of the Cartesian conception of the mind; Katalin Farkas offers a defence of an uncompromising internalist Cartesian conception. (shrink)

The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged (...) access.

Much debate has surrounded "switching" scenarios in which a subject's reasoning is said to exhibit the fallacy of equivocation ( Burge 1988 ; Boghossian 1992, 1994 ). Peter Ludlow has argued that such scenarios are "epistemically prevalent" and, therefore, epistemically relevant alternatives ( Ludlow 1995a ). Since a distinctive feature of the cases in question is that the subject blamelessly engages in conceptual equivocation, we may label them 'equivocational switching cases'. Ludlow's influential argument occurs in a discussion about compatibilism with (...) regards to anti-individualism (or content externalism) and self-knowledge. However, the issue has wide-reaching consequences for many areas of epistemology. Arguably, the claim that equivocational switching cases are epistemically relevant may bear on the epistemology of inference, testimony, memory, group rationality and belief revision. Ludlow's argument proceeds from a now well-known "down to Earth" switching-case of a subject, Biff, who travels between the US and the UK. I argue that Ludlow's case-based argument fails to support the general claim that conceptual equivocational switching cases are prevalent and epistemically relevant. Thus, the discussion addresses the basis of some poorly understood issues regarding the epistemological consequences of anti-individualism. Simultaneously, the discussion is broadened from the narrow focus on self-knowledge. Finally, the critical discussion serves as the basis for some general reflections on epistemic relevance and the epistemic risks associated with conceptual equivocation. Specifically, I suggest that philosophy is an area where the risk of conceptual equivocation is extraordinarily high. (shrink)

Our fundamental conception of the self seems to be, broadly speaking, epistemic: selves are things that have thoughts, undergo experiences, and possess reasons for action and belief. In this paper, I evaluate the consequences of this epistemic conception for the widespread view that properties like thinking that arthritis is painful are relational features of the self.

Knowledge of your own propositional attitudes requires at least two things. You need to know the content of the relevant mental state, and you need to know what attitude you take towards that content. If it is possible to mistake a wish for a belief, this is a mistake about the attitude, not the content. One need not believe that we are generally infallible about our mental states to hold that, typically, when I sincerely say..

A typical strategy of those who seek to show that externalism is compatible with authoritative knowledge of content is to show that externalism does nothing to undermine the claim that all thinkers can at any time form correct and justi?ed self-ascriptive judgements concerning their occurrent thoughts.

Most explorations of the epistemic implications of Semantic Anti- Individualism (SAI) focus on issues of self-knowledge (first-person au- thority) and/or external-world skepticism. Less explored has been SAIs implications forthe epistemology of reasoning. In this paperI argue that SAI has some nontrivial implications on this score. I bring these out by reflecting on a problem first raised by Boghossian (1992). Whereas Boghos- sians main interest was in establishing the incompatibility of SAI and the a priority of logical abilities (Boghossian 1992: 22), (...) I argue that Boghossians argument is better interpreted as pointing to SAIs implications for the na- ture of discursive justification. (shrink)

In her recent book Anti-Individualism and Knowledge, Jessica Brown has presented a novel answer to the self-knowledge achievement problem facing the proponent of anti-individualism. She argues that her answer is to be preferred to the traditional answer (based on Burge, 1988a). Here I present three objections to the claim that her proposed answer is to be preferred. The significance of these objections lies in what they tell us about the nature of the sort of knowledge that is in dispute. Perhaps (...) the most important lesson I draw from this discussion is that, given the nature of knowledge of one's own thoughts, discriminability (from relevant alternatives) is not a condition on knowledge as such.

Externalism1 is the thesis that some propositional attitudes depend for their individuation on features of the thinker’s (social and/or physical) environment. The doctrine of self-knowledge of thoughts is the thesis that for all thinkers S and occurrent thoughts that p, S has authoritative and non-empirical knowledge of her thought that p. A much-discussed question in the literature is whether these two doctrines are compatible. In this paper I attempt to respond to one argument for an incompatibilist conclusion, Boghossian’s 1989 ‘Memory (...) Argument.’. (shrink)
