Donald Davidson famously offered an explanation of “first-person authority”. However, he described first-person authority differently across different works—sometimes referring to the presumptive truth of agents’ self-ascriptions of their current mental states, and sometimes referring to the direct self-knowledge that agents often have of said states. First, I show that a standard Davidsonian explanation of first-person authority can at best, and with some modification, explain the presumptive truth of agents’ self-ascriptions. I then develop two Davidsonian accounts of direct self-knowledge—one accounting for (...) its function and another accounting for its source—pushing back in the process against deflationary and quietist rejoinders to these projects. Finally, I relate my Davidsonian accounts of direct self-knowledge back to the modified Davidsonian account of the presumptive truth of agents’ self-ascriptions. (shrink)

In this thesis, I elaborate and defend Donald Davidson's account of knowing one's own mental states that exhibit first-person authority. To that end, I place Davidson's account among others in the philosophical landscape concerning self-knowledge. Next, I examine his response to philosophical challenges that arise from mental content externalism and self-deception. Finally, I draw some insights froms Davidson's account to the broader aims of epsitemology.

In some of Plato’s early dialogues we find a concern with correctly ascertaining the contents of a particular kind of one’s own psychological states, cognitive states. Indeed, one of the achievements of the elenctic method is to facilitate cognitive self-knowledge. In the Alcibiades, moreover, Plato interprets the Delphic injunction, ‘know yourself’, as crucially requiring cognitive self-knowledge, and ending in knowing oneself as subject to particular epistemic norms. Epistemic authority for self-knowledge is, for Plato, conferred on the basis of correct application (...) of norms to cognitive self-ascriptions, and not confined to the first-personal perspective. This implies first-personal plural epistemic authority for self-knowledge. (shrink)

This chapter explores the topic of self-knowledge in ancient thought, asking in particular what the ancient concept (or concepts) of knowing oneself amounts to. The chapter begins by contrasting the issues which occupy ancient and contemporary discussions of self-knowledge, and the obvious points of continuity and discontinuity between the two. The author isolates two forms of self-knowledge: cognitive self-knowledge or knowledge of one’s own mental states, and dispositional self-knowledge or knowledge of one’s moral or intellectual dispositions, and traces the treatment (...) of these forms of self-knowledge in the works of Plato, Aristotle, Hellenistic philosophers, and Plotinus. In the course of discussing the texts of each thinker or school, and the relevant scholarship, this chapter also canvasses the ways in which the chapters in the rest of this volume seek to engage with some of the problems or issues that have emerged.

According to the transparency approach, achievement of self-knowledge is a two-stage process: first, the subject arrives at the judgment ‘p’; second, the subject proceeds to the judgment ‘I believe that p.’ The puzzle of transparency is to understand why the transition from the first to the second judgment is rationally permissible. After revisiting the debate between Byrne and Boyle on this matter, I present a novel solution according to which the transition is rationally permissible in virtue of a justifying argument (...) that begins from a premise referring to the mental utterance that is emitted in the course of judging ‘p.’.

Dretske is a “conciliatory skeptic” on self-knowledge. Take some subject S such that S thinks that P and S knows that she has thoughts. Dretske’s theory can be put as follows: S has a privileged way of knowing what she thinks, but she has no privileged way of knowing that she thinks it. There is much to be said on behalf of conciliatory skepticism and Dretske’s defense of it. We aim to show, however, that Dretske’s defense fails, in that if (...) his defense of CS’s skeptical half succeeds, then his defense of CS’s conciliatory half fails. We then suggest a potential way forward. We suggest in particular that the correct way of being a Dretskean conciliatory skeptic is to deny that S has a privileged way of knowing about her thoughts, but to grant that she is nonetheless an authority on her thoughts.

Putnam’s vat argument is intended to show that I am not a permanently envatted brain. The argument holds promise as a response to vat scepticism, which depends on the claim that I do not know that I am not a permanently envatted brain. However, there is a widespread idea that the vat argument cannot fulfil this promise, because to employ the argument as a response to vat scepticism I would have to make assumptions about the content of the premises and/or (...) conclusion of the argument that beg the question against the sceptic. In this paper, I show that this idea is mistaken. (shrink)

‘How, then, she had asked herself, did one know one thing or another thing about people, sealed as they were?’ So asks Lily Briscoe in To the Lighthouse. It is this question, rather than any concern about pretence or deception, which forms the basis for the philosophical problem of other minds. Responses to this problem have tended to cluster around two solutions: either we know others’ minds through perception; or we know others’ minds through a form of inference. In the (...) first part of this paper I argue that this debate is best understood as concerning the question of whether our knowledge of others’ minds is based on perception or based on evidence. In the second part of the paper I suggest that our ordinary ways of thinking take our knowledge of others’ minds to be both non- evidential and non-perceptual. A satisfactory resolution to the philosophical problem of other minds thus requires us to take seriously the idea that we have a way of knowing about others’ minds which is both non-evidential and non-perceptual. I suggest that our knowledge of others’ minds which is based on their expressions – our expressive knowledge - may fit this bill. (shrink)

If the contents of our thoughts are partly determined by facts outside our heads, can we still know those contents directly, without investigating our environment? What if we were surreptitiously switched to Twin-Earth? Would we know the contents of our thoughts under these unusual circumstances? By looking carefully at what determines the content of a second-order thought, a candidate for self-knowledge, the paper argues that we can know the contents of our thoughts directly, even after being switched. Learning about the (...) switch, however, does raise some interesting difficulties. (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.

The principal aim of my thesis is to provide a unified theory of imagining, that is, a theory which aspires to capture the common nature of all central forms of imagining and to distinguish them from all paradigm instances of non-imaginative phenomena. The theory which I intend to put forward is a version of what I call the Agency Account of imagining and, accordingly, treats imaginings as mental actions of a certain kind. More precisely, it maintains that imaginings are mental (...) actions that aim at the formation of episodic representations, the content of which is directly determined by what we want them to represent. My defence of this version of the Agency Account happens in two stages. On the one hand, I try to show that it is both extensionally adequate and explanatorily illuminating with respect to those mental states or projects which are clear instances of either imaginative or non- imaginative phenomena. And on the other hand, I seek to demonstrate that the most plausible alternative to the Agency Account - namely the Cognitive Account according to which it is distinctive of imaginings that they are non-cognitive phenomena and thus to be contrasted with perceptions, judgements, and so on - is bound to fail as a unified theory of imagining. The dissertation contains five main parts. In the first, I specify in more detail what a unified account of imagining has to achieve and, in particular, which phenomena it is supposed to capture. The second part presents the Cognitive Account, thereby focussing on Brian O'Shaughnessy's sophisticated version of it while the third part is reserved for the evaluation and rejection of the Cognitive Account. In the fourth part, I develop my version of the Agency Account of imagining. And the fifth and last part is concerned with the accommodation of potential counterexamples to it. (shrink)

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and so (...) you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

Internalist approaches to epistemic justification are, though controversial, considered a live option in contemporary epistemology. Accordingly, if ‘active’ externalist approaches in the philosophy of mind—e.g. the extended cognition and extended mind theses—are _in principle_ incompatible with internalist approaches to justification in epistemology, then this will be an epistemological strike against, at least the _prima facie_ appeal of, active externalism. It is shown here however that, contrary to pretheoretical intuitions, neither the extended cognition _nor_ the extended mind theses are in principle (...) incompatible with two prominent versions of epistemic internalism—viz., accessibilism and mentalism. In fact, one possible diagnosis is that pretheoretical intuitions regarding the incompatibility of active externalism with epistemic internalism are symptomatic of a tacit yet incorrect identification of epistemic internalism with epistemic individualism. Thus, active externalism is not in principle incompatible with epistemic internalism per se and does not significantly restrict one’s options in epistemology. (shrink)

It is widely accepted that knowledge of certain of one’s own mental states is authoritative in being epistemically more secure than knowledge of the mental states of others, and theories of self-knowledge have largely appealed to one or the other of two sources to explain this special epistemic status. The first, ‘detectivist’, position, appeals to an inner perception-like basis, whereas the second, ‘constitutivist’, one, appeals to the view that the special security awarded to certain self-knowledge is a conceptual matter. I (...) argue that there is a fundamental class of cases of authoritative self-knowledge, ones in which subjects are consciously thinking about their current, conscious intentional states, that is best accounted for in terms of a theory that is, broadly speaking, introspectionist and detectivist. The position developed has an intuitive plausibility that has inspired many who work in the Cartesian tradition, and the potential to yield a single treatment of the basis of authoritative self-knowledge for both intentional states and sensation states. (shrink)

Reliabilism is invoked by a standard causal response to the slow switching argument for incompatibilism about mental content externalism and privileged access. Though the response in question is negative, in that it only establishes that, given such an epistemology, externalism does not rule privileged access out, the appeal to reliabilism involves an assumption about the reliability of introspection, an assumption that in turn grounds a simple argument for the positive conclusion that reliabilism itself implies privileged access. This paper offers a (...) two-part defense of that conclusion: the reliabilist account of privileged access is defended both againstarguments in favor of the rival content inheritance strategy and against an argument turning on empirical considerations concerning the individuation of the belief-producing process of introspection. (shrink)

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

Among recent theories of the nature of self-knowledge, the rationalistic view, according to which self-knowledge is not a cognitive achievement—perceptual or inferential—has been prominent. Upon this kind of view, however, self-knowledge becomes a bit of a mystery. Although the rationalistic conception is defended in this article, it is argued that it has to be supplemented by an account of the transparency of belief: the question whether to believe that P is settled when one asks oneself whether P.

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)

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 this paper I address the question whether self-knowledge is compatible with an externalist individuation of mental content. Against some approaches, I consider self-knowledge as a genuine cognitive achievement. Though it is neither incorrigible nor infallible, self-knowledge is direct, a priori (no based on empirical investigation), presumptively true and authoritative. The problem is whether self-knowledge, so understood, is compatible with externalism. My answer will be affirmative. I will defend this species of compatibilism against several objections, in particular those based on (...) the possibility of an individual’s being unwittingly switched between worlds. (shrink)

Pacific Philosophical Quarterly, 80:2, 136-56 (June 1999).

It has become increasingly popular to suggest that non-individualistic theories of content undermine our purported a priori knowledge of such contents because they entail that we lack the ability to distinguish our thoughts from alternative thoughts with different contents. However, problems relating to such knowledge of 'comparative' content tell just as much against individualism as non-individualism. Indeed, the problems presented by individualistic theories of content for self-knowledge are at least, if not more, serious than those presented by non-individualistic theories. Consequently, (...) considerations of self-knowledge give one no reason to embrace individualism. If anything, they give one reason to reject it. (shrink)

The usual reading of Descartes' “anthropological” perspective classifies it as a radical dualism with a distinction between two substances, mind and body, which experience major interaction difficulties. Through a contextualization of Descartes' physiological and psychological thought as well as through a less fragmented reading of his work, we intend to review this traditional interpretation, thereby showing its distorted character. When we pay attention to passion, a new Descartes’ image as a sort of phenomenal monism appears, which is markedly different from (...) the legendary image typically associated with him, even today. (shrink)

Judgment internalism about evaluative judgments is the view that there is a necessary internal connection between evaluative judgments and motivation understood as desires. The debate about judgment internalism has reached a standoff some time ago. In this paper, I outline a new argument for judgment internalism. This argument does not rely on intuitions about cases, but rather it has the form of an inference to the best explanation. I argue that the best philosophical explanations of how we know what we (...) desire require that judgment internalism is true, which gives us a good reason to believe that judgment internalism is true. (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)

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary (...) to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all. (shrink)

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)

Propositional attitudes are often classified as non-phenomenal mental states. I argue that there is no good reason for doing so. The unwillingness to view propositional attitudes as being essentially phenomenal stems from a biased notion of phenomenality, from not paying sufficient attention to the idioms in which propositional attitudes are usually reported, from overlooking the considerable degree to which different intentional modes can be said to be phenomenologically continuous, and from not considering the possibility that propositional attitudes may be transparent, (...) just like sensations and emotions are commonly held to be: there may be no appropriate way of describing their phenomenal character apart from describing the properties and objects they represent. (shrink)

How is knowledge of the external world possible? How is knowledge of other minds possible? How is a priori knowledge possible? These are all examples of how-possible questions in epistemology. In this highly original book Quassim Cassam explains how such questions arise and how they should be answered.

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.”. (shrink)

I here argue against the viability of Peter Ludlow’s modified version of Paul Boghossian’s argument for the incompatibility of semantic externalism and authoritative self-knowledge. Ludlow contends that slow switching is not merely actual but is, moreover, prevalent; it can occur whenever we shift between localized linguistic communities. It is therefore quite possible, he maintains, that we undergo unwitting shifts in our mental content on a regular basis. However, there is good reason to accept as plausible that despite their prevalence we (...) are in fact able to readily adapt to such switches, as well as to the shifts in mental content that accompany them. The prevalence of slow switching between linguistic communities does not then necessarily entail incompatibility after all. (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)

According to the traditional view, beliefs and desires are mental representations that play particular functional roles. A belief that P is state which represents P and plays the belief-role, while a desire that P is a state which represents that P and plays the desire-role. In this dissertation I argue that the traditional view has trouble accounting for (a) role that belief and desire play in the causal and rational explanation of behaviour and (b) our knowledge of our own conscious, (...) occurrent beliefs and desires. -/- In its place I argue for Pure Attitude Representationalism (PAR), which holds that beliefs and desires are not to be distinguished from one another by their functional role, but instead entirely by their representational content. According to PAR, desires are distinct from beliefs not because they do different things, but because desires represent things as being rewarding. Throughout the three papers that comprise this dissertation I argue that PAR provides a better explanation of (a) and (b). (shrink)

Turning the techniques we use to understand other people onto ourselves can provide an insight into the types of self-knowledge that may be possible for us. Adopting Pluralistic Folk Psychology, according to which we understand others not primarily by thinking about invisible beliefs and desires that cause behavior, but instead by modeling others as people - with rich characters, relationships, past histories, cultural embeddedness, personality traits, and so forth. A preliminary investigation shows that we understand ourselves at least in terms (...) of our phenomenal states, informational states, perceptual states, traits, desires, and beliefs. I then appeal to empirical research to examine the accuracy of our sense of self-understanding in these ways, and argue that these are often non-veridical. Moreover, in our folk practices, we do not take our statements of self-understanding as infallible, but we allow others to help us see ourselves. While there is room for some improvement in our acurarcy, I conclude.. (shrink)

In this paper I provide an outline of a new kind of constitutive account of self-knowledge. It is argued that in order for the model properly to explain transparency, a further category of propositional attitudes—called “commitments”—has to be countenanced. It is also maintained that constitutive theories can’t remain neutral on the issue of the possession of psychological concepts, and a proposal about the possession of the concept of belief is sketched. Finally, it is claimed that in order for a constitutive (...) account properly to explain authority, it has to take a rather dramatic constructivist turn, which makes it suitable as an explanation of self-knowledge only for a limited class of mental states.

A great deal of discussion in the recent literature has been devoted to the so-called 'McKinsey' paradox which purports to show that semantic externalism is incompatible with the sort of authoritative knowledge that we take ourselves to have of our own thought contents. In this paper I examine one influential epistemological response to this paradox which is due to Crispin Wright and Martin Davies. I argue that it fails to meet the challenge posed by McKinsey but that, if it is (...) set within an externalist epistemology, it may have application to a related paradox that concerns the problem of radical scepticism.

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)

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.

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. (shrink)

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? (shrink)

I argue that, if content externalism is in tension with privileged access to content, then content externalism is also in tension with privileged access to phenomenal character. Content externalists may thus have a new problem on their hands. This is not because content externalism implies externalism about phenomenal character. My argument is compatible with the conviction that, unlike some propositional content, phenomenal character is not individuated by environmental factors. Rather, the argument involves considering in tandem two ideas which have become (...) prominent in the philosophy of mind concerning the introspection of phenomenal character. (shrink)

This paper addresses the question whether introspection plus externalism about mental content warrant an a priori refutation of external-world skepticism and ontological solipsism. The suggestion is that if thought content is partly determined by affairs in the environment and if we can have non-empirical knowledge of our current thought contents, we can, just by reflection, know about the world around us -- we can know that our environment is populated with content-determining entities. After examining this type of transcendental argument and (...) discussing various objections found in the literature, I argue that the notion of privileged self-knowledge underlying this argument presupposes that we can learn, via introspection, that our so-called thoughts are propositional attitudes rather than contentless states. If, however, externalism is correct and thought content consists in the systematic dependency of internal states on relational properties, we cannot know non-empirically whether or not we have propositional attitudes. Self-knowledge (apropositional attitude) is consistent with us lacking the ability to rule out, via introspection, the possibility that we don't have any propositional attitudes. Self-knowledge provides us with knowledge of what is in our minds, but not that we have minds. Hence, the combination of externalism with the doctrine of privileged self-knowledge does not allow for an a priori refutation of skepticism and is therefore unproblematic. (shrink)
