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

It is commonly held that our thoughts, beliefs, desires and feelings - the mental phenomena that we instantiate - are constituted by states and processes that occur inside our head. The view known as externalism, however, denies that mental phenomena are internal in this sense. The mind is not purely in the head. Mental phenomena are hybrid entities that straddle both internal state and processes and things occurring in the outside world. The development of externalist conceptions of the mind (...) is one of the most controversial, and arguably one of the most important, developments in the philosophy of mind in the second half of the twentieth century. Yet, despite its significance most recent work on externalism has been highly technical, clouding its basic ideas and principles. Moreover, very little work has been done to locate externalism within philosophical developments in both analytic and continental traditions. In this book, Mark Rowlands aims to remedy both these problems and present for the reader a clear and accessible introduction to the subject grounded in wider developments in the history of philosophy. Rowlands shows that externalism has significant and respectable historical roots that make it much more important than a specific eruption that occurred in late twentieth-century analytic philosophy.

In this paper, I shall defend externalism for the contents of perceptual experience. A perceptual experience has representational properties; it presents the world as being a certain way. A visual experience, for example, might present the world to a subject as containing a surface with a certain shape, lying at a certain distance, in a certain direction; perhaps a square with sides about 30 cm, lying about one metre in front of the subject, in a direction about 20 degrees (...) to the left of straight ahead.

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

It’s not implausible to think that whenever I have a justified noninferential belief that p, it is caused by a seeming that p. It’s also tempting to think that something contributes to the justification of my belief only if I hold my belief because of that thing. Thus, given that many of our noninferential beliefs are justified and that we hold them because of seemings, one might be inclined to hold a view like Phenomenal Conservatism, according to which seemings play (...) a crucial role—perhaps the only crucial role—in the justification of our noninferential beliefs. But Phenomenal Conservatism seems to conflict, in a number of ways, with externalist accounts of justification. As a result, the attractiveness of the intuitions appealed to in support of views like Phenomenal Conservatism present something of a challenge to externalism. The purpose of this paper is to deal with that challenge by developing and defending an externalist-friendly account of the role of seemings in the formation and justification of our noninferential beliefs—an account that incorporates what is attractive in views like Phenomenal Conservatism. Because this externalist-friendly account is compatible with both externalist accounts of justification and the plausible elements of views like Phenomenal Conservatism, the challenge to externalism inspired by such views is thereby undermined.

The Content Skeptic argues that a subject could not have introspective knowledge of a thought whose content is individuated widely. This claim is incorrect, relying on the tacit assumption that introspective knowledge differs significantly from other species of knowledge. The paper proposes a reliabilist model for understanding introspective knowledge according to which introspective knowledge is simply another species of knowledge, and according to which claims to introspective knowledge are not, as suggested by the Content Skeptic, defeated by the mere possibility (...) of error. This way of understanding introspective knowledge affords a robust theory of privileged access consistent with semantic externalism. (shrink)

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

Written by an international team of leading scholars, this collection of thirteen new essays explores the implications of semantic externalism for self-knowledge and skepticism, bringing recent developments in the philosophy of mind, the philosophy of language, and epistemology to bear on the issue. Structured in three parts, the collection looks at self-knowledge, content transparency, and then meta-semantics and the nature of mental content. The chapters examine a wide range of topics in the philosophy of mind and the philosophy of (...) language, including 2D semantics, transparency views of self-knowledge, and theories of linguistic understanding, as well as epistemological debates on contextualism, contrastivism, pragmatic encroachment, anti-luminosity arguments and testimony. The scope of the volume will appeal to graduate students and researchers in epistemology, philosophy of mind, philosophy of language, cognitive science, psychology and linguistics. (shrink)

Tyler Burge and other externalists about mental content have tried to accommodate privileged self-knowledge and to neutralize skepticism about one's ability to authoritatively know one's present thoughts. I show that, though Burgean compatibilism explains knowing it is p I believe, it doesn't explain how I can have privileged knowledge that the state I occupy is a state of believing rather than, say, a state of doubting. Moreover, given externalism, self-knowledge of attitudinal component is vulnerable to a certain kind of (...) error and so doesn't have the same kind of privilege as self-knowledge of current content.

If you want a philosophically diligent exposition of a theory, something that has got through review by conventional peers, go elsewhere (Honderich, 2004). If you want an understanding made more immediate by brevity and informality, read on. The theory is a Radical Externalism about the nature of consciousness. If it is not a complete departure from the cranialism of most of the philosophy and science of consciousness, it is a fundamental departure.

In ‘Mental Events’ Donald Davidson argued for the anomalism of the mental on the basis of the operation of incompatible constitutive principles in the mental and physical domains. Many years later, he has suggested that externalism provides further support for the anomalism of the mental. I examine the basis for that claim. The answer to the question in the title will be a qualified ‘Yes’. That is an important result in the metaphysics of mind and an interesting consequence of (...) externalism. (shrink)

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

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

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.

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.

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

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

Ryan Darby, Judith Edersheim, and Bruce Price (DEP) argue that patients with Behavioral-Variant Frontotemporal Dementia have intact moral knowledge. In effect, they assume a motivational externalist understanding of moral knowledge. We question this by probing the cases they present as evidence for their position.

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

Donald Davidson espouses two fundamental theses about the individuation of mental events. The thesis of causal individuation asserts that sameness of cause and effect is sufficient and necessary for event identity. The thesis of content individuation gives only a sufficient condition for difference of mental events: if e and f have different contents then they are different mental events. I argue that given these theses, psychological externalism--the view that mental content is determined by factors external to the subject of (...) the relevant mental events--entails that the token identity theory is false.

One of the most provocative projects in recent analytic philosophy has been the development of the doctrine of externalism, or, as it is often called, anti-individualism. While there is no agreement as to whether externalism is true or not, a number of recent investigations have begun to explore the question of what follows if it is true. One of the most interesting of these investigations thus far has been the question of whether externalism has consequences for the (...) doctrine that we have authoritative, a priori self-knowledge of our mental states. The selected works presented in this volume, some previously published, some new, are representative of this debate and open up new questions and issues for philosophical investigation, including the connection between externalism, self-knowledge, epistemic warrant, and memory.

Abstract. The dangerous level of individuality in contemporary Western culture is informed by a conception of mind, self, and soul as internal to the central nervous system. The historical development of this view has produced a bounded and self-contained individual at odds with communal life. Happily, scientific and philosophical studies of mind are coming to view the human mind as embodied, enactive, encultured, and embedded in social and technical networks, and as a construction not limited to the boundaries of the (...) individual organism. Mental phenomena are hybrids of events in the head and events in the world to which they are often coupled, not least of which are with other people. There are mutual and reciprocal implications of this externalism for a number of religious themes. Our understanding of redemption might better be bound to our relationships with others, including our bodies and our sexuality, rather than to a private, individual relationship with the sacred.

The "width" of the mind is an important topic in contemporary philosophical psychology. Support for active externalism derives from theoretical, engineering, and observational perspectives. Given the history of psychology, psychopathology is notable in its absence from the list of avenues of support for the idea that some cognitive processes extend beyond the physical bounds of the organism in question. The current project is to defend the possibility, plausibility, and desirability of externalist psychopathology. Doing so both adds to the case (...) for externalism and suggests ways of improving our study of cognitive dysfunction. I establish the possibility of externalist psychopathology through the development of models of wide cognitive processing, and, by implication, failure of such processing, from the work of S.L. Hurley and Robert Wilson. The plausibility of wide conceptualization and explanation of cognitive disorders is shown through an examination of apraxia, disorders of learned, skilled movements. The desirability of externalist psychopathology is suggested through a look at theoretical and therapeutic virtues, again drawing on Wilson's work. (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.

Abstract Temporal Externalism is the view that future events can contribute to determining the present content of our thoughts and utterances. Two objections to Temporal Externalism are discussed and rejected. The first is that Temporal Externalism has implausible consequences for the epistemology of biology and other taxonomic sciences (Brown, 2000). The second is that it is committed to implausible claims about dispositions.

The paper begins by examining the original Turing Test (2T) and Searle’s antithetical Chinese Room Argument, which is intended to refute the 2T in particular, as well as any formal or abstract procedural theory of the mind in general. In the ensuing dispute between Searle and his own critics, I argue that Searle’s ‘internalist’ strategy is unable to deflect Dennett’s combined robotic-systems reply and the allied Total Turing Test (3T). Many would hold that the 3T marks the culmination of the (...) dialectic and, in principle, constitutes a fully adequate empirical standard for judging that an artifact is intelligent on a par with human beings. However, the paper carries the debate forward by arguing that the sociolinguistic factors highlighted in externalist views in the philosophy of language indicate the need for a fundamental shift in perspective in a Truly Total Turing Test (4T). It’s not enough to focus on Dennett’s individual robot viewed as a system; instead, we need to focus on an ongoing system of such artifacts. Hence a 4T should evaluate the general category of cognitive organization under investigation, rather than the performance of single specimens. From this comprehensive standpoint, the question is not whether an individual instance could simulate intelligent behavior within the context of a pre-existing sociolinguistic culture developed by the human cognitive type. Instead the key issue is whether the artificial cognitive type itself is capable of producing a comparable sociolinguistic medium. (shrink)

Combining active externalism in the form of the extended and distributed cognition hypotheses with virtue reliabilism can provide the long sought after link between mainstream epistemology and philosophy of science. Specifically, by reading virtue reliabilism along the lines suggested by the hypothesis of extended cognition, we can account for scientific knowledge produced on the basis of both hardware and software scientific artifacts. Additionally, by bringing the distributed cognition hypothesis within the picture, we can introduce the notion of epistemic group (...) agents, in order to further account for collective knowledge produced on the basis of scientific research teams.

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

The aim of this paper is to show what sorts of logics are required by externalist and internalist accounts of the meanings of natural kind nouns. These logics give us a new perspective from which to evaluate the respective positions in the externalist-internalist debate about the meanings of such nouns. The two main claims of the paper are the following: first, that adequate logics for internalism and externalism about natural kind nouns are second-order logics; second, that an internalist second-order (...) logic is a free logic—a second order logic free of existential commitments for natural kind nouns, while an externalist second-order logic is not free of existential commitments for natural kind nouns—it is existentially committed.

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.

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

For traditional epistemologists like myself the rise in popularity of externalist epistemologies has made philosophical life more than a little difficult. The debate between internalist and externalist analyses of knowledge and justification has implications that range far beyond the immediate topic in dispute—the nature of knowledge and justified belief. This paper was written for a conference titled "Can Epistemology Be Unified?" Whether or not it can be unified, it certainly is not at the present time. To say that a field (...) of philosophy is unified is not, of course, to say that there is universal agreement on the answers to fundamental questions—if unification required that, then no field of philosophy would ever be unified. It is enough for epistemology to be unified that epistemologists recognize the legitimacy or philosophical interest of the same kinds of questions and recognize the legitimacy of the same general philosophical methodology. Both internalists and externalists are indeed addressing a common question when they ask about the nature of knowledge and justified belief, when the ask, that is, metaepistemological questions. Moreover, as far as I can tell, in attempting to answer metaepistemological questions, epistemologists employ more or less the classic methodology of analytic philosophy—analyses of epistemic concepts seek necessary and sufficient conditions for the application of epistemic concepts, and proposals are evaluated with the thought experiments that have been the stock in trade of analytic philosophy for centuries. The field of metaepistemology is unified. If the externalist's metaepistemology were correct, however, we would need to rethink the entire conceptual framework within which philosophers have addressed a host of epistemological and even metaphysical issues. If paradigm externalists were correct, philosophers, qua philosophers, should stop asking certain questions they used to find very interesting and should even abandon certain methods of doing philosophy. In this paper I am primarily interested in the implications of an externalist epistemology for the classic debate over direct realism concerning the external world. After suggesting that even externalists might need to abandon epistemological direct realism and outlining a problem that that might cause, I'll close with some very general remarks on how different the epistemic landscape becomes given the way in which externalists understand the distinction between inferentially and noninferentially justified belief.

Externalist representationalism is touted as a superior rival to naïve realism, and yet a careful analysis of the externalist representationalist's analysis of our ordinary perceptual experiences shows the view to be far closer to naïve realism than we might have expected. One of the central advertised benefits of representationalist views in general is that they are compatible with the idea that ordinary, illusory and hallucinatory perceptual experiences are of the same fundamental kind. Naïve realists are forced to deny the ‘common (...) fundamental kind claim’ and adopt disjunctivism. However, I argue that externalist representationalism is also a version of disjunctivism. Consequently, one of the main rivals to naïve realism turns out not to be a rival at all. (shrink)

When proponents of cognitive externalism (CE) turn to empirical studies in cognitive science to put the framework to use and to assess its explanatory success, they typically refer to perception, memory, or motor coordination. In contrast, not much has been said about reasoning. One promising avenue to explore in this respect is the theory of bounded rationality (BR). To clarify the relationship between CE and BR, we criticize Andy Clark's understanding of BR, as well as his claim that BR (...) does not fit his version of CE. We then propose and defend a version of CE—“scaffolded cognition”—that is not committed to constitutive claims about the mind, but still differs from mainstream internalism. Finally, we analyze BR from our own CE perspective, thereby clarifying its vague appeals to the environment, and argue that cognitive internalism cannot explain important aspects of the BR program.

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

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

(2001). Is Externalism about Content Inconsistent with Internalism about Justification? Australasian Journal of Philosophy: Vol. 79, No. 2, pp. 227-246.

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)

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

Introduction to externalism in the philosophy of mind and cognitive science.

Unlike conceptual analysis, conceptual engineering does not aim to identify the content that our current concepts do have, but the content which these concepts should have. For this method to show the results that its practitioners typically aim for, being able to change meanings seems to be a crucial presupposition. However, certain branches of semantic externalism raise doubts about whether this presupposition can be met. To the extent that meanings are determined by external factors such as causal histories or (...) microphysical structures, it seems that they cannot be changed intentionally. This paper gives an extended discussion of this ‘externalist challenge’. Pace Herman Cappelen’s recent take on this issue, it argues that the viability of conceptual engineering crucially depends on our ability to bring about meaning change. Furthermore, it argues that, contrary to first appearance, causal theories of reference do allow for a sufficient degree of meaning control. To this purpose, it argues that there is a sense of what is called ‘collective long-range control’, and that popular versions of the causal theory of reference imply that people have this kind of control over meanings.
