What is the distinctively philosophical problem of perception? Here it is argued that it is the conflict between the nature of perceptual experience as it intuitively seems to us, and certain possibilities which are implicit in the very idea of experience: possibilities of illusion and to the world' which involves direct awareness of existing objects and their properties. But if one can have an experience of the same kind without the object being there -- a hallucination of an object -- (...) then it seems that perceptual experience cannot essentially be such a relation. This is the fundamentally philosophical problem of perception; the various philosophical theories of perception in the 20th and 21st centuries can be seen as responses to it. (shrink)

This paper discusses Husserl’s theory of intentionality and compares it to contemporary debates about intentionalism. I first show to what extent such a comparison could be meaningful. I then outline the structure of intentionality as found in Ideas I. My main claims are that – in contrast with intentionalism – intentionality for Husserl covers just a region of conscious contents; that it is essentially a relation between act-processes and presented content; and that the side of act-processes contains non-representational contents. In (...) the third part, I show that Husserl also offers resources against intentionalism’s exclusive concern with propositional content. (shrink)

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, the question can be confused (...) with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. (shrink)

Stroud has argued for many years that skepticism is conditionally correct. We cannot, he claims, both undergo a Cartesian-style examination of the extent of our knowledge as well as avoid skepticism. One reason Stroud's position appears quite plausible is the so-called "totality condition" imposed for this kind of examination: as inquiring philosophers we are called upon to assess all of our knowledge, all at once. However, in this paper I argue that Stroud's apparent understanding of the totality condition is mistaken. (...) Evidently, Stroud thinks that honoring the totality condition amounts to imposing the strong requirement that we initially assume that we don't know anything about external reality. However, there is a weaker requirement available: that we initially not assume that we know anything about external reality. I argue i) that the weaker conception of the totality condition is most suitable for the kind of philosophical examination that Stroud seems to have in mind; and ii) that according to this same conception skepticism is not conditionally correct.

Dogmatists and phenomenal conservatives think that if it perceptually seems to you that p, then you thereby have some prima facie justification for believing that p. Increasingly, writers about these views have argued that perceptual seemings are composed of two other states: a sensation followed by a seeming. In this article we critically examine this movement. First we argue that there are no compelling reasons to think of perceptual seemings as so composed. Second we argue that even if they were (...) so composed, this underlying disunity in metaphysical or psychological structure would fall below the threshold of epistemic significance. (shrink)

According to the Disjunction Problem, teleological theories of perceptual content are unable to explain why it is that a subject represents an F when an F causes the perception and not the disjunction F v G, given that the subject has mistaken G’s for F’s in the past. Without an adequate explanation these theories are stuck without an account of how non-veridical representation is possible, which would be an unsettling result. In this paper I defend Burge’s teleological theory of perception (...) against the Disjunction Problem, arguing that a perceptual state’s representing what I call an error-prohibiting disjunctive property is incompatible with the truth of perceptual anti-individualism. And because perceptual anti-individualism is at the heart of Burge’s theory, I conclude that Burgeans need not be concerned with the Disjunction Problem. (shrink)

The dissertation concerns on the theory of perception of David Hume. The problem of perception is the problem about the object of perception. According to Jerome Valberg, the problem of perception is an antinomy. For Hume the problem is a dilemma between two theories, direct realism and representative realism. For direct realism, the object of perception is a mind-indipendent object; for representative realism, the object of perception is a mind-dependent object or an internal one. In the chapter I, I have (...) focused on the positions of Descartes and John Locke. In the chapter II, I have presented the conception of Hume through three different arguments: the argument from illusion, the argument from secondary qualities and the argument from hallucination. Then, I have exposed the Humean objections to the proofs of external world and the theory about belief in an unperceived existence. Hume’s position is the following: the object of perception is an internal object and the representative realism is unverifiable, but not false. It follows, then, that for Hume direct realism is false. In the chapter III, I have compared the theory of Hume with contemporary direct realism, namely, with intentionalism of John Searle and Micheal Huemer, with externalism of Tyler Burge and disjunctivism by Michael Martin. I have argued that Hume’s theory is more consistent than intentionalism of Searle and Huemer and it can’t be objected by externalism and disjunctivism. (shrink)

The thesis evaluates a contemporary debate concerning the very possibility of thinking about the world. In the first chapter, McDowell's critique of Davidson is presented, focusing on the coherentism defended by the latter. The critique of the myth of the given (as it appears in Sellars and Wittgenstein), as well as the necessity of a minimal empiricism (which McDowell finds in Quine and Kant), lead to an oscillation in contemporary thinking between two equally unsatisfactory ways of understanding the empirical content (...) of thought. In the second chapter, I defend Davidson's approach, focusing on his theory of interpretation and semantic externalism, as well as on the relation between causes and reasons. In the third chapter, the debate is analyzed in more detail. I criticize the anomalous monism, the way in which the boundaries between the conceptual and the non-conceptual are understood by Davidson, as well as the naturalized Platonism defended by McDowell. This thesis is mainly negative, and it concludes by revealing problems in both positions under evaluation. (shrink)

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

How should we understand the relationship between the contents of our color, causal, modal, and evaluative beliefs, on the one hand, and color, causal, modal, and evaluative properties, on the other? According to Barry Stroud (2011), because of the nature of the contents of those types of beliefs, we should also think that what he calls a “negative metaphysical verdict” on the latter is not one that we could consistently maintain. The metaphysical project aims to arrive at an improved conception (...) of ourselves and our relation the world, no matter if that conception is positive or negative. But if Stroud is right that we cannot consistently arrive at the view that all of our causal, modal, and evaluative beliefs are systematically false, we will see that we cannot consistently reach the negative verdict. But failure to reach the negative verdict doesn’t mean that we have reached the positive verdict. Stroud calls this philosophical failure “metaphysical dissatisfaction”. In this paper, I argue that we can appropriate a metaepistemological response to the problem of the external world which shares its core features with Stroud’s (2000, 2011) arguments, but which nevertheless leaves us with a distinctive kind of epistemological dissatisfaction.

This chapter contains section titled: Externalism and Authoritative Self‐Knowledge The “Fully Cartesian” Conception Externalism and Authoritative Self‐Knowledge A Suggestion.

According to epistemic internalism, the only facts that determine the justificational status of a belief are facts about the subject’s own mental states, like beliefs and experiences. Externalists instead hold that certain external facts, such as facts about the world or the reliability of a belief-producing mechanism, affect a belief’s justificational status. Some internalists argue that considerations about evil demon victims and brains in vats provide excellent reason to reject externalism: because these subjects are placed in epistemically unfavorable settings, externalism (...) seems unable to account for the strong intuition that these subjects’ beliefs are nonetheless justified. I think these considerations do not at all help the internalist cause. I argue that by appealing to the anti-individualistic nature of perception, it can be shown that skeptical scenarios provide no reason to prefer internalism to externalism. (shrink)

Externalism about mental content is now widely accepted. It is therefore surprising that there is no established definition of externalism. I believe that this is a symptom of an unrecognized fact: that the labels 'mental content externalism' -- and its complement 'mental content internalism' -- are profoundly ambiguous. Under each of these labels falls a hodgepodge of sometimes conflicting claims about the organism's contribution to thought contents, the nature of the self, relations between the individual and her community, and the (...) epistemic availability of thoughts. This situation stems from the fact that contributors to debates about externalism differ in how they understand 'internal property'; these differences reveal (or, perhaps, generate) disparate conceptions of what is at issue in these debates. I argue that this situation is irremediable. There is no way to understand 'internal property' that will conform with prevailing beliefs about the nature of internalism and externalism, and with the usual taxonomy of leading positions. This ambiguity carries a heavy price: participants in these debates often argue at cross-purposes, disagreeing even on the nature of the evidence that could settle the question of externalism. Progress on the broad range of issues associated with these debates requires that we abandon the categories 'internalism' and 'externalism'. I close by suggesting a promising avenue for future research related to these issues. (shrink)

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another. (shrink)

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do not (...) contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

Externalism is widely endorsed within contemporary philosophy of mind and language. Despite this, it is far from clear how the externalist thesis should be construed and, indeed, why we should accept it. In this entry I distinguish and examine three central types of externalism: what I call foundational externalism, externalist semantics, and psychological externalism. I suggest that the most plausible version of externalism is not in fact a very radical thesis and does not have any terribly interesting implications for philosophy (...) of mind, whereas the more radical and interesting versions of externalism are quite difficult to support.

Knowing one’s past thoughts and attitudes is a vital sort of self-knowledge. In the absence of memorial impressions to serve as evidence, we face a pressing question of how such self-knowledge is possible. Recently, philosophers of mind have argued that self-knowledge of past attitudes supervenes on rationality. I examine two kinds of argument for this supervenience claim, one from cognitive dynamics, and one from practical rationality, and reject both. I present an alternative account, on which knowledge of past attitudes is (...) inferential knowledge, and depends upon contingent facts of one’s rationality and consistency. Failures of self-knowledge are better explained by the inferential account. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

Book description: Much contemporary philosophical debate centres on the topics of logic, thought and language, and on the connections between these topics. This collection of articles is based on the Royal Institute of Philosophy’s annual lecture series for 2000–2001. Its contributors include a number of those working at the forefront of the field, and in their papers they reflect their own current pre-occupations. As such, the volume will be of interest to all philosophers, whether their own work is within the (...) areas of language and thought or not. (shrink)

Sense-perception—the awareness or apprehension of things by sight, hearing, touch, smell and taste—has long been a preoccupation of philosophers. One pervasive and traditional problem, sometimes called “the problem of perception”, is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? The present entry is about how these possibilities of error challenge the intelligibility of the phenomenon of (...) perception, and how the major theories of perception in the last century are best understood as responses to this challenge.

It is argued that Husserl was an “externalist” in at least one sense. For it is argued that Husserl held that genuinely perceptual experiences—that is to say, experiences that are of some real object in the world—differ intrinsically, essentially and as a kind from any hallucinatory experiences. There is, therefore, no neutral “content” that such perceptual experiences share with hallucinations, differing from them only over whether some additional non-psychological condition holds or not. In short, it is argued that Husserl was (...) a “disjunctivist”. In addition, it is argued that Husserl held that the individual object of any experience, perceptual or hallucinatory, is essential to and partly constitutive of that experience. The argument focuses on three aspects of Husserl’s thought: his account of intentional objects, his notion of horizon, and his account of reality. (shrink)

It is close to current orthodoxy that perceptual experience is to be characterized, at least in part, by its representational content, roughly, by the way it represents things as being in the world around the perceiver. Call this basic idea the content view.

While engaged in the analysis of topics such as the nature of knowledge, meaning, or justice, analytic philosophers have traditionally relied extensively on their own intuitions about when the relevant terms can, and can't, be correctly applied. Consequently, if intuitions about possible cases turned out not to be a reliable tool for the proper analysis of philosophically central concepts, then a radical reworking of philosophy's (or at least analytic philosophy's) methodology would seem to be in order. It is thus not (...) surprising that the increasingly critical scrutiny that intuitions have received of late has produced what has been referred to as a "crisis" in analytic philosophy. This paper will argue, however, that at least those criticisms that stem from recent work on semantic externalism are not as serious as their proponents have claimed. Indeed, this paper will argue while the conceptual intuitions (and the analyses that result from them) will have to be recognized as fallible, they still have a prima facie claim to correctness. A naturalistic and externalistic account of concepts thus merely requires that the methodology of conceptual analysis be reinterpreted (from a 'Platonic' to a 'constructive' model) rather than given up.

SummaryIn this paper I discuss two influential views in the philosophy of mind: the two‐component picture draws a distinction between ‘narrow content’ and ‘broad content’, while radical externalism denies that there is such a thing as narrow content. I argue that ‘narrow content’ is ambiguous, and that the two views can be reconciled. Instead of considering that there is only one question and three possible answers corresponding to Cartesian internalism, the two‐component picture, and radical externalism respectively, I show that there (...) are two distinct questions: ‘Are mental contents internal to the individual?’ and, ‘Are mental contents analysable in two‐components?’ Both questions can be given a positive or a negative answer, in such a way that there are four, rather than three, possible views to be distinguished. The extra view whose possibility emerges in this framework is that which mixes radical externalism with the two‐component picture. It agrees with radical externalism that there cannot be ‘solipsistic’ contents: content is not an intrinsic property of the states of an individual organism, but a relational property. It also agrees with the two‐component picture, on a certain interpretation: the broad content of a psychological state depends upon what actually causes that state, but the narrow content depends only on what normally causes this type of state to occur. In the last section of the paper, I deal with internal representation which seem to be independent even of the normal environment. I show that such contents are themselves independent of the normal environment only in a relative sense: they are locally independent of the normal environment, yet still depend on it via the concepts to which they are connected in the concept system.

In my 1991 paper, AAnti-Individualism and Privileged Access,@ I argued that externalism in the philosophy of mind is incompatible with the thesis that we have privileged , nonempirical access to the contents of our own thoughts.¹ One of the most interesting responses to my argument has been that of Martin Davies (1998, 2000, and Chapter _ above) and Crispin Wright (2000 and Chapter _ above), who describe several types of cases to show that warrant for a premise does not always (...) transmit to a known deductive consequence of that premise, and who contend that this fact under-mines my argument for incompatibilism. I will try to show here that the Davies/Wright point about transmission of warrant does not adversely affect my argument. (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)

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)

The Burge-Putnam thought experiments have generated the thesis that beliefs are not fixed by the constitution of the body. However, many philosophers have thought that if this is true then there must be another content-like property. Even if the contents of our attitudes such as the one in ‘believes that aluminum is a light metal’, do not supervene on our physical makeups, nevertheless people who are physical duplicates must be the same when it comes to evaluating their rationality and explaining (...) their actions. I argue that the considerations motivating this view are best handled with just the ordinary ‘that’-clause contents. (shrink)

There has frequently been taken to be a tension, if not an incompatibility, between "externalist" theories of content (which allow the make-up of one's physical environment and the linguistic usage of one's community to contribute to the contents of one's thoughts and utterances) and the "methodologically individualist" intuition that whatever contributes to the content of one's thoughts and utterances must ultimately be grounded in facts about one's own attitudes and behavior. In this dissertation I argue that one can underwrite such (...) externalist theories within a methodologically individualistic framework by understanding semantic norms in terms of the need to reach, for each of one's terms, a type of "equilibrium." Each speaker's commitment to making her _own_ beliefs and applications consistent allows one to incorporate these 'external' factors into the contents of their thoughts and utterances in a way that remains methodologically individualistic. Methodologically individualistic accounts are typically taken to be unable to incorporate 'external' factors such as the world's physical make-up or communal usage because of arguments suggesting that the individual's own beliefs and usage underdetermine or even misidentify what, according to externalist accounts, they mean by their terms. These arguments, however, only seem plausible if one presupposes a comparatively impoverished conception of the individual's beliefs. The beliefs a speaker associates with a given term extend far beyond the handful of sentences they would produce if asked to list such beliefs. In particular, speakers have an implicit, but rich, understanding of their language, their world, and the relation between them. Speakers typically understand languages as shared temporally extended practices about which they can be, both individually and collectively, mistaken. Once this conception of language is taken into account, the ascriptions which purportedly forced 'non-individualistic' conceptions of content upon us (particularly ascriptions which seemed to tie what we meant to social use rather than our own beliefs) turn out to be ultimately grounded in the individual's own beliefs. Indeed, our self-conception does much more than merely underwrite 'non-individualistic' ascriptions.. (shrink)

Anti-individualists claim that concepts are individuated with an eye to purely external facts about a subject's environment about which she may be ignorant or mistaken. This paper offers a novel reason for thinking that anti-individualistic concepts are an ineliminable part of commonsense psychology. Our commitment to anti-individualism, I argue, is ultimately grounded in a rational epistemic agent's commitment to refining her own representational practices in the light of new and surprising information about her environment. Since anti-individualism is an implicit part (...) of responsible epistemic practices, we cannot abandon it without compromising our own epistemic agency. The story I tell about the regulation of one's own representational practices yields a new account of the identity conditions for anti-individualistic concepts. (shrink)

In this paper I argue against Twin-Earth externalism. The mistake that Twin Earth arguments rest on is the failure to appreciate the force of the following dilemma. Some features of things around us do matter for the purposes of conceptual classification, and others do not. The most plausible way to draw this distinction is to see whether a certain feature enters the cognitive perspective of the experiencing subject in relation to the kind in question or not. If it does, we (...) can trace conceptual differences to internal differences. If it doesn’t, we do not have a case of conceptual difference. Neither case supports Twin Earth externalism. (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. (shrink)

To sum up, then, both kinds of Putnam's arguments established externalism, though they suffer from several defects. Yet, I think Searle's discussion of these arguments contributes to our understanding of what makes externalism true, and forces us to accept a moderate version of externalism. Searle's own account of the TE story shows us, within a solipsistic outline, how two identical mental states can be directed towards different objects, and further, that the content-determination of indexical thoughts does not necessarily involve external (...) factors. We are thus led to search elsewhere (i.e., not in the nature of indexical thoughts nor in the mere fact of there being identical thoughts with different intentionalities) for what makes the thoughts in question ‘external’. Searle formulates the thesis that intension determines extension as asserting that intension sets certain conditions that anything has to meet in order to fall under its extension. I showed that this is a trivial and implausible understanding of that thesis. Yet, it leads us to distinguish between an intension's setting conditions for falling under its extension and its fully determining such conditions, and thus to see in what sense externalism is true: in the sense that there are intensions that do not fully determine the conditions for falling under their extensions. Rather, they leave indeterminacies. This version of externalism is a moderate one, since though the intensions do not fully determine extensions, they, so to speak, determine their indeterminacies, by specifying the possible external facts that can complete the determination of extension. (The intensions, as I said, function like open sentences, and can be viewed as narrow contents.) So what's in the head plays a much more important role in determining content than Putnam takes it to play. Searle's pointing out that Hilary's concepts ‘elm’ and ‘beech’ are different also contributes to seeing this phenomenon: we realize that in that case the difference between the concepts is what is responsible for the fact that the completions of the extension-determinations are different. I think that this way of viewing the facts shows that ‘the externalist turn’ is not a great revolution, and that with the help of the concept of narrow content we can accept it without abandoning the traditional views about the mind as the source of content, and without being embarrassed by the very idea of (realistic) belief-desire psychology.

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

Internalism and externalism disagree about whether agents who are internally the same can differ in their mental states. But what is it for two agents to be internally the same? Standard formulations take agents to be internally the same in virtue of some metaphysical fact, for example, that they share intrinsic physical properties. Our aim in this chapter is to argue that such formulations should be rejected. We provide the outlines of an alternative formulation on which agents are internally the (...) same in virtue of facts about their epistemic capacities. The resulting formulation is one on which internalism and externalism are views about the extent to which an agent’s mental states can vary independently of the capacity for introspective discrimination. We suggest that this epistemic formulation of internalism and externalism picks out a substantive disagreement in philosophical theorizing about the nature of the mind. (shrink)

Liberals about perceptual contents claim that perceptual experiences can represent kinds and specific, familiar individuals as such; they also claim that the representation of an individual or kind as such by a perceptual experience will be reflected in the phenomenal character of that experience. Conservatives always deny the latter and sometimes also the former claim. I argue that neither liberals nor conservatives have adequately appreciated how the content internalism/externalism debate bears on their views. I show that perceptual content internalism entails (...) conservativism when conjoined with one other, extremely plausible premise. Hence, liberals are committed to perceptual contents externalism, yet they have failed to fully address the consequences that this has for their view. Moreover, the argument is easily adapted to perceptual experiences of Twin Earthable properties, like colour and shape. I use this last result to show why existing conservative arguments that appeal to Twin Earth plausibly overgeneralize. (shrink)

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

Como posso estar certo de que existe qualquer coisa de externa aos meus próprios pensamentos? Muitos filósofos procuraram ou apresentar uma prova da existência do mundo externo, ou rejeitar a inteligibilidade da própria ideia de uma “prova” nesse contexto. O objetivo desse artigo é mostrar que o denominado “problema do mundo externo” decorre de uma má compreensão acerca do que seja justificativa epistêmica. Apresento o que denomino “paradoxo de Berkeley” de modo a mostrar que o uso ordinário da linguagem não (...) deve funcionar como critério de correção para a aplicação de conceitos como conhecimento e existência. Concluo que tanto as tentativas tradicionais de se apresentar uma prova da existência do mundo externo quanto as tentativas de se mostrar que o problema não faz sentido são equivocadas. O que deve ser levado em conta no exame do problema do mundo externo é o contexto em que a proposta cética é feita. (shrink)

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

Annotated bibliography of works on externalism and internalism in the philosophy of mind.

_ Source: _Page Count 25 This is a pre-print. Please cite only the revised published version. This paper presents an original, ambitious, truth-directed transcendental argument for the existence of an ‘external world’. It begins with a double-headed starting-point: Stroud’s own remarks on the necessary conditions of language in general, and Hegel’s critique of the “fear of error.” The paper argues that the sceptical challenge requires a particular critical concept of thought as that which may diverge from reality, and that this (...) concept is possible only through reflection on situations of error, in which how things are thought to be diverges from how things really are with independent items in an objective world. The existence of such a world is therefore a necessary condition of the possibility of scepticism: such scepticism is therefore false. I defend the argument against objections from Stroud’s sceptic and others. Drawing on Heidegger, the paper concludes by indicating that the chain of necessary conditions includes practical engagement with the world. (shrink)

According to the phenomenal intentionality research program, a state’s intentional content is fixed by its phenomenal character. Defenders of this view have little to say about just how this grounding is accomplished. I argue that without a robust account of representation, the research program promises too little. Unfortunately, most of the well-developed accounts of representation – asymmetric dependence, teleosemantics, and the like – ground representation in external relations such as causation. Such accounts are inconsistent with the core of the phenomenal (...) intentionality program. I argue that, however counter-intuitive it may seem, the best prospect for explaining how phenomenal character represents appeals to resemblance. (shrink)

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral (...) theory, which I call ‘moral externalism’, emerges. (shrink)

What is knowledge of one's own current, consciously entertained intentional states a form of inner awareness? If so, what form? In this paper I explore the prospects for a quasi-observational account of a certain class of cases where subjects appear to have self-knowledge, namely, the so-called cogito-like cases. In section one I provide a rationale for the claim that we need an epistemology of self-knowledge, and specifically, an epistemology of the cogito-like cases. In section two I argue that contentful properties (...) in such cases have two features in common with observational properties of objects. In section three, I develop a quasi-observational account of self-knowledge for the cogito-like cases by considering various accounts of the nature of observational properties (specifically, secondary qualities) and by applying them to these cases. I conclude by addressing some important objections to the account. (shrink)

Externalism in the philosophy of mind is threatened by the view that subjects are authoritative with regard to the contents of their own intentional states. If externalism is to be reconciled with first-person authority, two issues need to be addressed: (a) how the non-evidence-based character of knowledge of one's own intentional states is compatible with ignorance of the empirical factors that individuate the contents of those states, and (b) how, given externalism, the non-evidence-based character of such knowledge could place its (...) subject in an authoritative position. This paper endorses a standard strategy for dealing with (a). The bulk of the paper is devoted to (b). The aim is to develop an account of first-person authority for a certain class of intentional states that is capable of explaining (1) why knowledge of one's own intentional states is peculiarly authoritative, and (2) why such authority is compatible with externalism.

What is the epistemological role of speech perception in comprehension? More precisely, what is its role in episodes or states of comprehension able to mediate the communication of knowledge? One answer, developed in recent work by Tyler Burge, has it that its role may be limited to triggering mobilizations of the understanding. I argue that, while there is much to be said for such a view, it should not be accepted. I present an alternative account, on which episodes of comprehension (...) are better able to underwrite the interpersonal transmission of knowledge. (shrink)
