Externalism and Slow Switching

This draft now appears (in revised form) as Chapter 6 of _Self-Reflection for the Opaque Mind_. See http://philpapers.org/rec/PARSFT-3.

In this paper I take side on externalist incompatibilism. However, I intend to radicalize the position. First, based on my criticism of Burge's anaphoric proposal, I argue that there is no reasoning‐transparency: the reasoner is blind to the reasoning he is performing. Second, assuming a global form of content‐externalism, I argue that “in the head” are only logical and formal abilities. That is what I call “bite the bullet and swallow it too.”.

_Self-Reflection for the Opaque Mind_ attempts to solve a grave problem about critical self-reflection. Psychological studies indicate not just that we are bad at detecting our own "ego-threatening" thoughts; they also suggest that we are ignorant of even our ordinary thoughts. However, self-reflection presupposes an ability to know one’s own thoughts. So if ignorance is the norm, why attempt self-reflection? While admitting the psychological data, this book argues that we are infallible in a limited range of self-discerning judgments—that in some (...) cases, these judgments are self-fulfilling or self-verifying. Even so, infallibility does not imply indubitability, and the author does not wish to provide a "foundation" for empirical knowledge. The point is rather to explain how self-reflection as a rational activity is possible. The book will be of interest to scholars working on the issue of self-reflection across a wide range of disciplines, including philosophy, psychology, and cognitive science. (shrink)

My concern in this paper is with the claim that knowledge is a mental state – a claim that Williamson places front and centre in Knowledge and Its Limits. While I am not by any means convinced that the claim is false, I do think it carries certain costs that have not been widely appreciated. One source of resistance to this claim derives from internalism about the mental – the view, roughly speaking, that one’s mental states are determined by one’s (...) internal physical state. In order to know that something is the case it is not, in general, enough for one’s internal physical state to be a certain way – the wider world must also be a certain way. If we accept that knowledge is a mental state, we must give up internalism. One might think that this is no cost, since much recent work in the philosophy of mind has, in any case, converged on the view that internalism is false. This thought, though, is too quick. As I will argue here, the claim that knowledge is a mental state would take us to a view much further from internalism than anything philosophers of mind have converged upon. (shrink)

Minha proposta, nesta introdução a “Autoconhecimento e os limites da autenticidade”, texto de Sven Bernecker traduzido e publicado neste número de Sképsis, é dar razões para que defensores do anti-individualismo que sejam partidários da estratégia do autoconhecimento básico, no que diz respeito ao debate sobre a compatibilidade entre anti-individualismo e conhecimento de si, mudem de posição, e passem a defender anti-individualismo com teoria da autenticidade.

In the last twenty-five years, several authors have raised problems to the thesis that privileged self-knowledge is compatible with content externalism. In particular, the 'slow-switching' argument, which was originally put forth by Paul Boghossian (1989), aims to show that there is no satisfactory account of how we can have privileged knowledge about our own thoughts given content externalism. Though many philosophers have found ways to block the argument, no one has worried to address a major worry that Boghossian had when (...) he presented the argument, which is to understand under which conditions privileged self-knowledge is possible given content externalism. In this paper, I offer a diagnosis of why the slow-switching argument fails and I show how the diagnosis enables us to provide a partial response to Boghossian's worry. (shrink)

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. (shrink)

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.

Entry on the Stanford Encyclopedia of Philosophy. A summary of the literature on whether externalism about thought content precludes non-empirical knowledge of one's own thoughts.

Based on content externalism, the question of whether self-knowledge is authoritative or not has launched a real controversy in the philosophy of mind. Boghossian proposed slow switching argument in defense of incompatibility of the two views. This argument has been criticized by some philosophers through different approaches. Vahid is one of them. He claimed that Boghossian's argument appeals to some controversial assumptions without which it cannot achieve its conclusion. In this article, I criticize Vahid's response to slow switching argument and (...) show that self-knowledge in Vahid's response differs in having authority and therefore in function from that of Boghossian. (shrink)

One of the main arguments intended to show that content externalism undermines the privileged access thesis is the ‘slow switching argument’, originally proposed by Boghossian. In this argument, it is supposed that a subject is unknowingly switched back and forth between Earth and Twin Earth: then it is claimed that, given externalism, when the subject is on Earth thinking that water is wet, he cannot know the content of his thought a priori, for he cannot, by mere reflection, rule out (...) the relevant alternative hypothesis that he is on Twin Earth thinking that twater is wet. One of the controversies surrounding this argument stems from the fact that it is not clear which epistemological principle underlies it. Here, I examine two suggestions made in the literature as to what that underlying principle might be. I argue that neither of these suggested principles is plausible, and thus that the slow switching argument never gets off the ground. (shrink)

In this paper, I challenge a widely presupposed principle in the epistemology of inference. The principle, (Validity Requirement), is this: S’s (purportedly deductive) reasoning, R, from warranted premise-beliefs provides (conditional) warrant for S’s belief in its conclusion only if R is valid. I argue against (Validity Requirement) from two prominent assumptions in the philosophy of mind: that the cognitive competencies that constitute reasoning are fallible, and that the attitudes operative in reasoning are anti-individualistically individuated. Indeed, my discussion will amount to (...) a defence of anti-individualism against a novel ‘slow-switch’ argument against it. This argument contra anti-individualism has it that given anti-individualism and certain auxiliary assumptions, A, a switched reasoner may, in certain slow-switch circumstances, C, reason invalidly by equivocating concepts. More specifically: -/- (Valid 0): Peter is in circumstances C, and auxiliary assumptions, A, hold.(Valid 1): If Peter is in circumstances C, and auxiliary assumptions A hold, then (if the attitudes operative in Peter’s reasoning R are anti-individualistically individuated, then R is not valid). (Valid 2): Peter’s reasoning, R, generates warrant for the conclusion-belief. (Valid 3): Peter’s reasoning, R, generates warrant for the conclusion-belief only if the reasoning, R, is valid. (Valid 4): So, the attitudes operative in Peter’s reasoning R are not anti-individualistically individuated. -/- The argument involves weaker premises than those of familiar slow-switch arguments against anti-individualism. In particular, it requires only that the reasoning be de facto valid. This assumption is much weaker than the requirement that the validity of the reasoning be ‘transparent’ to the reasoner. Indeed, (Valid 3) is simply an instance of (Validity Requirement). However, I argue that anti-individualism and (Valid 0)–(Valid 2) should be upheld at the expense of (Valid 3). In consequence, (Validity Requirement) stands in need of restriction. Thus, I argue for a surprising result in the epistemology of inference from widely accepted assumptions in the philosophy of mind. (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.

Semantic externalism holds that the content of at least some of our thoughts is partly constituted by external factors. Accordingly, it leads to the unintuitive consequence that we must then often be mistaken in what we are thinking, and any kind of claim of privileged access must be given up. Those who deny that semantic externalists can retain any account of self-knowledge are ‘incompatibilists’, while those who defend the compatibility of self-knowledge with semantic externalism are ‘compatibilists’. This paper examines the (...) claim of compatibilism, focusing on Burge’s “Slow Switching Argument” and Boghossian’s “Objection of Relevant Alternatives”. I argue that compatibilism is false, and that semantic externalism is incompatible with self-knowledge. (shrink)

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.

There is a thesis that assure the computability between externalize about mental content and self-knowledge (BURGE, 1988). However, this theses, that explore the auto-verification property of claims of the type “I think that p”, works only for assertive claims that are express in the simple present tense. Among the problematic cases are the claims in the past tense and claims about specific propositional attitude. This fails about the thesis of the compatibility is pointed by Boghossian (1992) as a prove of (...) the incompatibility between externalism and self-knowledge. There is a wide bibliography that try to manage the claims in past tense. In these articles (BURGE, 1995), It's argued that the preservative function of memory assure the veracity of the claims in past tense (at last in normal situations). However, there isn't a lot of work about the problem of the claims about specific propositional attitude. This article propose a expanse the preservative memory theory, with the purpose that It manages the self-knowledge of past propositional attitudes. We propose some criteria that define when a claim of this type is true, mainly in the cases that the content of the attitude of the past thought is not identical with the actual thought. The criterion about the similarity of content is the Bernecker's one (2009). The criterion about similarity of attitudes is new: the attitude that S thinks in t1 as if he have had in t2 is similar with the attitude that he had in t 1 iff the actual attitude is entailed by the former.

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.

Judgments about the validity of at least some elementary inferential patterns(say modus ponens) are a priori if anything is. Yet a number of empirical conditions mustin each case be satisfied in order for a particular inference to instantiate this or that inferentialpattern. We may on occasion be entitled to presuppose that such conditions aresatisfied (and the entitlement may even be a priori), yet only experience could tell us thatsuch was indeed the case. Current discussion about a perceived incompatibility betweencontent externalism (...) and first-person authority exemplifies how damaging the neglect ofsuch empirical presuppositions of correct reasoning can be. An externalistic view of mentalcontent is ostensibly incompatible with the assumption that a rational subject should beable to avoid inconsistency no matter what the state of her empirical knowledge may be.That fact, however, needs not be taken (as it often is) as a reductio of externalism: alternatively,we may reject that assumption, adding to the agenda of a philosophical investigationof rationality an examination of the vicissitudes of logical luck. I offer an illustrationand defense of that alternative. (shrink)

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)

According to the received view, externalist grounds or reasons need not be introspectively accessible. Roughly speaking, from an externalist point of view, a belief will be epistemically justified, iff it is based upon facts that make its truth objectively highly likely. This condition can be satisfied, even if the epistemic agent does not have actual or potential awareness of the justifying facts. No inner perspective on the belief-forming mechanism and its truth-ratio is needed for a belief to be justified. In (...) my view, this is not the whole story. While I agree that introspective access to our reasons is a defining feature of justification for the access internalist, not the externalist, I will argue that even for the latter, some kind of introspective access is an epistemic desideratum. Yet, even given that I am right, the desirable might not be achievable for us. Recent psychological research suggests that we do not dispose of reliable introspection into the sources of our own beliefs. This seems to undermine the claim that we can introspectively know about the reasons upon which our beliefs are based. In this paper I will therefore additionally show why these results do not threaten the kind of introspective access desirable from an externalist point of view. (shrink)

En décadas recientes se ha considerado que una formulación adecuada del autoconocimiento (AC) debería ser consistente con la tesis del externalismo (E). Michael McKinsey es uno de los personajes que ha enfatizado con mayor ahínco que la conjunción de ambas posturas es inconsistente. En este trabajo defiendo la idea de que las objeciones presentadas por McKinsey no afectan de manera importante la formulación davidsoniana de la autoridad de la primera persona (AC3) en conjunción con (E); señalo, además, que si no (...) pudiera hacerse una reconstrucción à la Davidson de (AC3) desde la postura de McKinsey sería en virtud de las diferencias metodológicas, semánticas, epistemológicas y ontológicas entre ambos autores, y no debido a que esta reconstrucción en sí misma sea incompatible con el externalismo.

I discuss Burge's argument that our entitlement to self-knowledge consists in the constitutive relation between the second-order review of thoughts and the thoughts reviewed, and defend it against Peacocke's criticism. I then argue that though our entitlement to self-knowledge is neutral to different environments, as Burge claims, the consideration of Burge's own notion of brute error shows that Burge's effort to reconcile externalism and self-knowledge is not successful.

The development of the semantic externalism in the 1970s was followed by a debate on the compatibility of externalism and self-knowledge. Boghossian’s memory argument is one of the most important arguments against the compatibilist view. However, some compatibilists attack Boghossian’s argument by pointing out that his understanding of memory is internalistic. Ludlow and others developed the externalist view of memory to defend the compatibility of externalism and self-knowledge. However, the externalist view of memory undermines the epistemic status of memory since (...) it gives memory a burden that is too heavy for it to carry. This paper argues that only if we take the content of memory to be narrow and take that of self-knowledge to be wide and replace Cartesian self-knowledge with contextually constrained self-knowledge, can the compatibility of externalism and self-knowledge be effectively defended.

This volume presents a series of influential essays by Paul Boghossian on the theory of content and on its relation to the phenomenon of a priori knowledge. The essays are organized under four headings: the nature of content; content and self-knowledge; knowledge, content, and the a priori; and colour concepts.

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)

Robert Stalnaker opposes the traditional view that knowledge of one's own current thoughts and feelings is the unproblematic foundation for all knowledge. He argues that we can understand our knowledge of our thoughts and feelings only by viewing ourselves from the outside, by seeing our inner lives as features of the world as it is in itself.

The question of whether content externalism poses a threat to the traditional view of self-knowledge has been much debated. Compatibilists have tried to diffuse the threat by appealing to the self-verifying character of reflexive judgments about our own thoughts, while incompatibilists have strenuously objected that this does not suffice. In my paper I argue that this debate is fundamentally misconceived since it is based, on both sides, on the problematic notion of ‘knowledge of content’. What this shows, I argue, is (...) not that content externalism is unobjectionable, but that the real challenge to content externalism is not an epistemological one. The real difficulty concerns the content externalist’s seemingly necessary commitment to the idea that individuals have an incomplete grasp of the concepts that go into their own thoughts. This idea poses a threat not to self-knowledge, I argue, but rather to our first- and second-order reasoning abilities. (shrink)

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 this paper I outline and defend an introspectionist account of authoritative self-knowledge for a certain class of cases, ones in which a subject is both thinking and thinking about a current, conscious thought. My account is distinctive in a number of ways, one of which is that it is compatible with the truth of externalism.

Descartes held the view that a subject has infallible beliefs about the contents of her thoughts. Here, I first examine a popular contermporary defense of this claim, given by Burge, and find it lacking. I then offer my own defense appealing to a minimal thesis about the compositionality of thoughts. The argument has the virtue of refraining from claims about whether thoughts are “in the head;” thus, it is congenial to both internalists and externalists. The considerations here also illuminate how (...) a subject may have epistemicially priviledged and a priori beliefs about her own thoughts. (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. (shrink)

The question of whether externalism about mental content is compatible with privileged access is a question of ongoing concern within philosophy of mind. Some philosophers think that Tyler Burge's early work on what he calls "basic self-knowledge" shows that externalism and privileged access are compatible. I critically assess this claim, arguing that Burge's work does not establish the compatbility thesis.

In two previous papers I explained why I believe that a certain sort of argument that seems to support skepticism about self-knowledge is actually self-undermining, in the sense that no one can justifiably accept all of its premises at once. Anthony Brueckner has recently tried to show that even if the central premises of my explanation are true, the skeptical argument in question is not self-undermining. He has also suggested that even if the skeptical argument is self-undermining, it can still (...) serve as a _reductio ad absurdum of the assumption that we have self-knowledge. My goal in this paper is to explain why I think neither of these responses is successful. (shrink)

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)
