In addiction, apparently causally significant phenomena occur at a huge number of levels; addiction is affected by biomedical, neurological, pharmacological, clinical, social, and politico-legal factors, among many others. In such a complex, multifaceted field of inquiry, it seems very unlikely that all the many layers of explanation will prove amenable to any simple or straightforward, reductive analysis; if we are to unify the many different sciences of addiction while respecting their causal autonomy, then, what we are likely to need is (...) an integrative framework. In this paper, we propose the theory of “Externalist” or “4E” – for extended, embodied, embedded, and enactive – cognition, which focuses on the empirical and conceptual centrality of the wider extra-neural environment to cognitive and mental processes, as a candidate for such a framework. We begin in Section 2 by outlining how such a perspective might apply to psychiatry more generally, before turning to some of the ways it can illuminate addiction in particular: Section 3 points to a way of dissolving the classic dichotomy between the “choice model” and “disease model” in the addiction literature; Section 4 shows how 4E concepts can clarify the interplay between the addict’s brain and her environment; and Section 5 considers how these insights help to explain the success of some recovery strategies, and may help to inform the development of new ones.

Medical assistance in dying, which includes voluntary euthanasia and assisted suicide, is legally permissible in a number of jurisdictions, including the Netherlands, Belgium, Switzerland and Canada. Although medical assistance in dying is most commonly provided for suffering associated with terminal somatic illness, some jurisdictions have also offered it for severe and irremediable psychiatric illness. Meanwhile, recent work in the philosophy of psychiatry has led to a renewed understanding of psychiatric illness that emphasises the role of the relation between (...) the person and the external environment in the constitution of mental disorder. In this paper, I argue that this externalist approach to mental disorder highlights an ethical challenge to the practice of medical assistance in dying for psychiatric illness. At the level of the clinical assessment, externalism draws attention to potential social and environmental interventions that might have otherwise been overlooked by the standard approach to mental disorder, which may confound the judgement that there is no further reasonable alternative that could alleviate the person’s suffering. At the level of the wider society, externalism underscores how social prejudices and structural barriers that contribute to psychiatric illness constrain the affordances available to people and result in them seeking medical assistance in dying when they otherwise might not have had under better social conditions. (shrink)

Externalist theories hold that a comprehensive understanding of mental disorder cannot be achieved unless we attend to factors that lie outside of the head: neural explanations alone will not fully capture the complex dependencies that exist between an individual’s psychiatric condition and her social, cultural, and material environment. Here, we firstly offer a taxonomy of ways in which the externalist viewpoint can be understood, and unpack its commitments concerning the nature and physical realization of mental disorder. Secondly, we apply (...) a strongly externalist approach to the case of Autistic Spectrum Disorder, and argue that this condition can be illuminated by appeal to the hypothesis of extended cognition. We conclude by briefly considering the significance this strongly externalist approach may have for psychiatric practice and pedagogy. (shrink)

The paper considers whether psychiatric kinds can be natural kinds and concludes that they can. This depends, however, on a particular conception of ‘natural kind’. We briefly describe and reject two standard accounts – what we call the ‘stipulative account’ (according to which apparently a priori criteria, such as the possession of intrinsic essences, are laid down for natural kindhood) and the ‘Kripkean account’ (according to which the natural kinds are just those kinds that obey Kripkean semantics). We then (...) rehearse a more permissive account: Richard Boyd’s ‘homeostatic property cluster’ (HPC) account. We argue that psychiatric kinds can in principle count as natural kinds on the HPC account. Moreover, specific psychiatric kinds (Tourette’s, schizophrenia, etc.) can be natural kinds even if the category psychiatric disorder is not itself a natural kind. (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)

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. (shrink)

I develop and argue for a kind of externalism about certain kinds of non-doxastic attitudes that I call policy externalism. Policy externalism about a given type of attitude is the view that all the reasonable policies for having attitudes of that type will not involve the agent's beliefs that some relevant conditions obtain. My defense primarily involves attitudes like hatred, regret, and admiration, and has two parts: a direct deductive argument and an indirect linguistic argument, an inference (...) to the best explanation of some strange ways we use certain conditionals. The main thought throughout is that attitudes we reason with, like belief, are very different from attitudes we don't reason with, in a way that constrains the former but not the latter. Finally, I investigate some consequences of policy externalism, including that it secures the possibility of genuine conditional apologies. (shrink)

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) (...) even granting (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

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)

This paper examines some of the interactions between holism, contextualism, and externalism, and will argue that an externalist metasemantics that grounds itself in certain plausible assumptions about self- knowledge will also be a contextualist metasemantics, and that such a contextualist metasemantics in turn resolves one of the best known problems externalist theories purportedly have with self-knowledge, namely the problem of how the possibility of various sorts of ‘switching’ cases can appear to undermine the ‘transparency’ of our thoughts (in particular, (...) our ability to tell, with respect to any two occurrent thoughts, whether they exercise the same or different concepts).

Teleology has a complicated history in the biological sciences. Some have argued that Darwin’s theory has allowed biology to purge itself of teleological explanations. Others have been content to retain teleology and to treat it as metaphorical, or have sought to replace it with less problematic notions like teleonomy. And still others have tried to naturalize it in a way that distances it from the vitalism of the nineteenth century, focusing on the role that function plays in teleological explanation. No (...) consensus has seemed possible in this debate. This paper takes a different approach. It argues that teleology is a perfectly acceptable scientific notion, but that the debate took an unfortunate misstep some 2300 years ago, one that has confused things ever since. The misstep comes in the beginning of Aristotle’s Physics when a distinction is made between two types of teleological explanation. One type pertains to artifacts while the other pertains to entities in nature. For Aristotle, artifacts are guided by something external to themselves, human intentions, while natural entities are guided by an internal nature. We aim to show that there is, in fact, only one type of legitimate teleological explanation, what Aristotle would have considered a variant of an artifact model, where entities are guided by external fields. We begin with an analysis of the differences between the two types of explanation. We then examine some evidence in Aristotle’s biological works suggesting that on account of his natural-artifactual distinction, he encountered difficulties in trying to provide teleological accounts of spontaneous generation. And we show that it is possible to resolve these difficulties with a more robust version of an artifact model of teleology, in other words, with an externalist teleology. This is McShea’s model, in which goal-directed entities are guided by a nested series of upper-level fields. To explain teleological behavior, this account invokes only external physical forces rather than mysterious internal natures. We then consider how field theory differs from other efforts to naturalize teleology in biology. And finally, we show how the account enables us to grapple with certain difficult cases – genes and intentions – where, even in biology today, the temptation to posit internal natures remains strong.

In this article I argue for a novel theory of representational content, which I call ‘subjective externalism’. The view combines an internal, subjective constraint on the attribution of thought content which traditionally underpins internalist theories of thought, and an external, objective constraint on the attribution of thought content which traditionally underpins externalist theories of thought. While internalism and externalism are mutually inconsistent, the constraints to which each theory is committed are not. It is this realization that opens up (...) the conceptual space for subjective externalism, according to which the correct attribution of thought content to an individual is essentially constrained by her nonrepresentational relations to objective manifest properties in her wider reality. (shrink)

This article presents a novel challenge to epistemic internalism. The challenge rests on a set of cases which feature subjects forming beliefs under conditions of “bad ideology”—that is, conditions in which pervasively false beliefs have the function of sustaining, and are sustained by, systems of social oppression. In such cases, the article suggests, the externalistic view that justification is in part a matter of worldly relations, rather than the internalistic view that justification is solely a matter of how things stand (...) from the agent’s individual perspective, becomes the more intuitively attractive theory. But these “bad ideology” cases do not merely yield intuitive verdicts that favor externalism over internalism. These cases are, moreover, analogous to precisely those canonical cases widely taken to be counterexamples to externalism: cases featuring brains-in-vats, clairvoyants, and dogmatists. That is, such “bad ideology” cases are, in all relevant respects, just like cases that are thought to count against externalism—except that they intuitively favor externalism. This, the author argues, is a serious worry for internalism. What is more, it bears on the debate over whether externalism is a genuinely “normative” epistemology. (shrink)

This paper argues for externalism about justification on the basis of thought experiments. I present cases in which two individuals are intrinsically and introspectively indistinguishable and in which intuitively, one is justified in believing that p while the other is not. I also examine an argument for internalism based on the ideas that we have privileged access to whether or not our own beliefs are justified and that only internalism is compatible with this privilege. I isolate what I take (...) to be the most plausible form of privileged access to justification and show that it is compatible with externalism. (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. (shrink)

Temporal externalists argue that ascriptions of thought and utterance content can legitimately reflect contingent conceptual developments that are only settled after the time of utterance. While the view has been criticized for failing to accord with our “ordinary linguistic practices”, such criticisms (1) conflate our ordinary ascriptional practices with our more general beliefs about meaning, and (2) fail to distinguish epistemically from pragmatically motivated linguistic changes. Temporal externalism relates only to the former sort of changes, and the future usage (...) relevant to what we mean reflects reason-driven practices that are rational for us to defer to. (shrink)

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as (...) a rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

In this paper, I defend externalist accounts of justified belief from Cohen's new evil demon objection. While I think that Cohen might be right that the person is justified in believing what she does, I argue that this is because we can defend the person from criticism and that defending a person is a very different thing from defending a person's attitudes or actions. To defend a person's attitudes or actions, we need to show that they met standards or did (...) not violate norms. Intuitions about whether we can defend a person from criticism are a poor guide when it comes to determining whether norms were violated or standards were met. It turns out that even radical forms of externalism about justification are compatible with the intuitions that Cohen's example elicits. Properly understood, those intuitions show that the believer should be excused from criticism (and excused for failing to believe with adequate justification). (shrink)

The failure of psychiatry to validate its diagnostic constructs is often attributed to the prioritizing of reliability over validity in the structure and content of the Diagnostic and Statistical Manual of Mental Disorders. Here I argue that in fact what has retarded biomedical approaches to psychopathology is unwarranted optimism about diagnostic discrimination: the assumption that our diagnostic tests group patients together in ways that allow for relevant facts about mental disorder to be discovered. I consider the Research Domain Criteria framework (...) as a new paradigm for classifying objects of psychiatric research that solves some of the challenges brought on by this assumption. (shrink)

We distinguish and discuss two different accounts of the subject matter of theories of reference, meta-externalism and meta-internalism. We argue that a form of the meta- internalist view, “moderate meta-internalism”, is the most plausible account of the subject matter of theories of reference. In the second part of the paper we explain how this account also helps to answer the questions of what kind of concept reference is, and what role intuitions have in the study of the reference relation.

Semantic externalism in contemporary philosophy of language typically – and often tacitly – combines two supervenience claims about idiolectical meaning (i.e., meaning in the language system of an individual speaker). The first claim is that the meaning of a word in a speaker’s idiolect may vary without any variation in her intrinsic, physical properties. The second is that the meaning of a word in a speaker’s idiolect may vary without any variation in her understanding of its use. I here (...) show that a conception of idiolectical meaning is possible that accepts the “anti-internalism” of the first claim while rejecting (what I shall refer to as) the “anti-individualism” of the second. According to this conception, externally constituted idiolectical meaning supervenes on idiolectical understanding. (shrink)

Dry earth seems to its inhabitants (our intrinsic duplicates) just as earth seems to us, that is, it seems to them as though there are rivers and lakes and a clear, odorless liquid flowing from their faucets. But, in fact, this is an illusion; there is no such liquid anywhere on the planet. I address two objections to externalism concerning the nature of the concept that is expressed by the word 'water' in the mouths of the inhabitants of dry (...) earth. Gabriel Segal presents a dilemma for the externalist concerning the application conditions of the concept, and Paul Boghossian presents a dilemma for the externalist concerning the complexity of the concept. I show that, in both cases, the externalist may occupy the horn of his choice without departing from either the letter or spirit of externalism. (shrink)

In this paper I challenge recent externalist interpretations of Ockham’s theory of intuitive cognition. I begin by distinguishing two distinct theses that defenders of the externalist interpretation typically attribute to Ockham: a ‘direct reference thesis’, according to which intuitive cognitions are states that lack all internal, descriptive content; and a ‘causal thesis’, according to which intuitive states are wholly determined by causal connections they bear to singular objects. I then argue that neither can be plausibly credited to Ockham. In particular, (...) I claim that the causal thesis doesn’t square with Ockham’s account of supernaturally produced intuition and that the direct reference thesis sits uneasily with Ockham’s characterization of the intentional structure of intuitive states.

The chapter traces the history of psychiatric ethics with a focus on the emergence of autonomy and how assumptions and thresholds surrounding informed consent and decision-making capacity have changed over the centuries. Innovators like Philippe PInel and William Tuke are featured in this account of how the 'mad' and the abuses of the 'domestication paradigm' of madness eventually gave way to more humanitarian approaches of treating the 'mad', like moral treatment. The chapter closes with a brief reflection regarding the (...) limits of autonomy and the decline of paternalism in psychiatric ethics. (shrink)

This paper focuses on a combination of the antiskeptical strategies offered by semantic externalism and the inference to the best explanation. I argue that the most difficult problems of the two strategies can be solved, if the strategies are combined: The strategy offered by semantic externalism is successful against standard skeptical brain-in-a-vat arguments. But the strategy is ineffective, if the skeptical argument is referring to the recent-envatment scenario. However, by focusing on the scenario of recent envatment the most (...) difficult problems of the antiskeptical strategy posed by the inference to the best explanation can be solved. The most difficult problems with this strategy are: Why is an explanation of our experience offered by the skeptical hypothesis more complex than our standard explanation? Why is the more complex explanation less likely to be true? By focussing on the recent envatment hypothesis both questions can be answered satisfactorily. Therefore, the combination of semantic externalism and the inference to the best explanation yields a powerful antiskeptical argument. (shrink)

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then (...) examine first the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

There are powerful reasons to think of perceptual content as determined at least in part by the environment of the perceiving subject. Externalist views such as this are often rejected on grounds that they do not give a good account of hallucinations. The chapter shows that this reason for rejecting content externalism is not well founded if we embrace a moderate externalism about content, that is, an externalist view on which content is only in part dependent on the (...) experiencing subject“s environment. The chapter starts by motivating content externalism. It then argues that hallucinations are best understood in terms of a deficiency of veridical perceptual experiences. The chapter discusses the consequences of this thesis by developing a view of hallucinations that is committed to externalism about content. (shrink)

In psychiatry some disorders of cognition are distinguished from instances of normal cognitive functioning and from other disorders in virtue of their surface features rather than in virtue of the underlying mechanisms responsible for their occurrence. Aetiological considerations often cannot play a significant classificatory and diagnostic role, because there is no sufficient knowledge or consensus about the causal history of many psychiatric disorders. Moreover, it is not always possible to uniquely identify a pathological behaviour as the symptom of a (...) certain disorder, as disorders that are likely to differ both in their causal histories and in their overall manifestations may give rise to very similar patterns of behaviour. -/- Consider delusions as an example. It wouldn’t be correct to define delusions as those beliefs people form as a result of a neurobiological deficit and a hypothesis-evaluation deficit (as some versions of the two-factor theory of delusions suggest), because for some delusions no neurobiological deficit may be found, and reasoning biases and motivational factors may be contributors to the formation of the delusion (e.g. McKay et al., 2005). Moreover, it would be a mistake to define delusions as symptoms of schizophrenia alone, because they occur also in other disorders, including dementia, amnesia, and delusional disorders. Thus, aetiological considerations may appear in the description and analysis of delusions, but do not feature prominently in their definition. -/- In this paper I argue that the surface features used as criteria for the classification and diagnosis of disorders of cognition are often epistemic in character. I shall offer two examples: confabulations and delusions are defined as beliefs or narratives that fail to meet standards of accuracy and justification. Although classifications and diagnoses based on features of people’s observable behaviour are necessary at these early stages of neuropsychiatric research, given the variety of conditions in which certain phenomena appear, I shall attempt to show that current epistemic accounts of confabulations and delusions have limitations. Epistemic criteria can guide both research and clinical practice, but fail to provide sufficient conditions for the identification of delusions and confabulations, and fail to demarcate pathological from non-pathological narratives or beliefs. -/- Another limitation of current epistemic accounts – which I shall not address here – is the excessive focus on epistemic faults of confabulations and delusions at the expense of their epistemically neutral or advantageous features (see Bortolotti and Cox, 2009). This may lead to a misconception of delusions and confabulations, and to an oversimplification in the assessment of the needs of people who require clinical treatment for their psychotic symptoms.

A recent argument against content internalism bucks tradition: it abandons Twin-Earth-style thought experiments and instead claims that internalism is inconsistent with plausible principles relating belief contents and truth values. Call this the transparency argument. Here, it is shown that there is a structurally parallel argument against content internalism’s foil: content externalism. Preserving the transparency argument while fending off the parallel argument against externalism requires that content-determination and truth-value-determination are implausibly linked together and that eternalism about belief contents is (...) true. Given these requirements, there may be reason to prefer simple, thought-experiment-based arguments against internalism – the sort of arguments that the transparency argument is meant to supersede.

I put forward an externalist theory of social understanding. On this view, psychological sense making takes place in environments that contain both agent and interpreter. The spatial structure of such environments is social, in the sense that its occupants locate its objects by an exercise in triangulation relative to each of their standpoints. This triangulation is achieved in intersubjective interaction and gives rise to a triadic model of the social mind. This model can then be used to make sense of (...) others’ observed actions. Its possession plays a vital role in the development of the capacity for false belief reasoning. The view offers an integrated account of the development of social cognition from primary intersubjectivity to level-2 perspective taking. It incorporates insights from interactionism and mindreading theories of social cognition and thus offers a way out of the stalemate between defenders of the two views. Because psychological sense making is perspectival, the frame problem does not arise for social reasoners: the perspective they bring to bear on the action that is to be interpreted constrains the information they can select to make sense of what others do.

Abstracting away from its various particular versions, contemporary externalism about knowledge can be broadly characterized as the rejection of two central ideas: that knowledge is incompatible with reflective awareness of the possibility of error, and that knowledge is necessarily tied to the resources that are available from within the first-person perspective. In this brief introduction, I outline five distinctly externalist accounts of knowledge, and two distinctly externalist methodological approaches to knowledge, all fitting this general description.

I defend externalism about color experiences and color thoughts, which I argue color objectivism requires. Externalists face the following question: would a subject's wearing inverting lenses eventually change the color content of, for instance, those visual experiences the subject reports with “red”? From the work of Ned Block, David Velleman, Paul Boghossian, Michael Tye, and Fiona Macpherson, I extract problems facing those who answer “Yes” and problems facing those who answer “No.” I show how these problems can be overcome, (...) leaving externalism available to the color objectivist. (shrink)

For non-analytic ethical naturalists, externalism about moral motivation is an attractive option: it allows naturalists to embrace a Humean theory of motivation while holding that moral properties are real, natural properties. However, Michael Smith has mounted an important objection to this view. Smith observes that virtuous agents must have non-derivative motivation to pursue specific ends that they believe to be morally right; he then argues that this externalist view ascribes to the virtuous agent only a direct de dicto desire (...) to do what is morally right, but not a direct motivation to be kind, help those in need, et. I first clarify this “fetishism objection”; I then show how the non-analytical naturalist can provide an understanding of virtuous motivation that is immune to this objection. (shrink)

The externalist says that your evidence could fail to tell you what evidence you do or not do have. In that case, it could be rational for you to be uncertain about what your evidence is. This is a kind of uncertainty which orthodox Bayesian epistemology has difficulty modeling. For, if externalism is correct, then the orthodox Bayesian learning norms of conditionalization and reflection are inconsistent with each other. I recommend that an externalist Bayesian reject conditionalization. In its stead, (...) I provide a new theory of rational learning for the externalist. I defend this theory by arguing that its advice will be followed by anyone whose learning dispositions maximize expected accuracy. I then explore some of this theory’s consequences for the rationality of epistemic akrasia, peer disagreement, undercutting defeat, and uncertain evidence. (shrink)

ABSTRACT Our ascriptions of content to past utterances assign to them a level of conceptual continuity and determinacy that extends beyond what could be grounded in the usage up to their time of utterance. If one accepts such ascriptions, one can argue either that future use must be added to the grounding base, or that such cases show that meaning is not, ultimately, grounded in use. The following will defend the first option as the more promising of the two, though (...) this ultimately requires understanding the relation between use and meaning as ‘normative’ in two important ways. The first way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between actual and correct use. The second sort of normativity is unique to theories that extend the grounding base into the future. In particular, if meaning is partially a function of future use, we can see our commitment to the ‘determinacy’ of meaning as a practical commitment that structures our linguistic practices rather than a theoretical commitment that merely describes them.

I look at incompatibilist arguments aimed at showing that the conjunction of the thesis that a subject has privileged, a priori access to the contents of her own thoughts, on the one hand, and of semantic externalism, on the other, lead to a putatively absurd conclusion, namely, a priori knowledge of the external world. I focus on arguments involving a variety of externalism resulting from the singularity or object-dependence of certain terms such as the demonstrative ‘that’. McKinsey argues (...) that incompatibilist arguments employing such externalist theses are at their strongest, and conclusively show that privileged access must be rejected. While I agree on the truth of the relevant externalist theses, I show that all plausible versions of the incompatibilist reductio argument as applied to such theses are fundamentally flawed, for these versions of the argument must make assumptions that lead to putatively absurd knowledge of the external world independently of the thesis of privileged access.

Another paper exploring the relation between Temporal externalism and Epistemicism about Vagueness, but with slightly more emphasis on the role of constitutive norms relating to our concept of truth.

In recent years, some epistemologists have argued that practical factors can make the difference between knowledge and mere true belief. While proponents of this pragmatic thesis have proposed necessary and sufficient conditions for knowledge, it is striking that they have failed to address Gettier cases. As a result, the proposed analyses of knowledge are either lacking explanatory power or susceptible to counterexamples. Gettier cases are also worth reflecting on because they raise foundational questions for the pragmatist. Underlying these challenges is (...) the fact that pragmatic epistemologies not only rely upon normative theories of rational choice but also require externalist standards to rule out epistemic luck. Unfortunately, we lack adequate externalist theories of rational choice. In response, I address these foundational challenges by offering the outlines of an externalist decision theory. While this task is an ambitious one that I cannot hope to complete, I survey the outlines of a decision-theoretic framework on which a richer pragmatic epistemology can be developed. My hope is that this framework opens up new avenues of exploration for the pragmatic epistemologist. (shrink)

This paper argues that participants in the subjectivism/objectivism/hybridism debate, a central issue in recent meaning in life research, conflate two different distinctions marked by the terms objective and subjective, one having to do with the question of whether life's meaningfulness depends on factors internal or external to the agent, the other having to do with the question of whether there is any ‘absolute’ as opposed to ‘relative’ truth about the first question. The paper then argues that a distinctive type of (...) hybridism with respect to the first sense is true. To vindicate this type of hybridism, the paper identifies, by using examples and counterexamples, internal and external necessary conditions for having meaningful lives. In this type of hybridism, internal states that are not directed at external factors, such as autonomy, serenity and contentment, are also taken account of, and, more generally, internal and external factors need not relate to each other at all. Further, although the more a combination of internal and external factors is valuable the more meaningful a life is, not any increase in the value of any relevant internal or external factor enhances meaning.

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

'Epistemic' theories of vagueness notoriously claim that (despite the appearances to the contrary) all of our vague terms have sharp boundaries, it's just that we can't know what they are. Epistemic theories are typically criticized for failing to explain (1) the source of the ignorance postulated, and (2) how our terms could come to have such precise boundaries. Both of these objections will, however, be shown to rest on certain 'presentist' assumptions about the relation between use and meaning, and if (...) allows that the meaning constitutive elements of our linguistic practices can extend into the future, the possibility of a new sort of 'normative epistemicism' emerges.

According to one brand of 'externalism', cognitive theories should individuate mental content 'widely'--that is, partly in terms of environmental features. David Marr's theory of vision is often cited in support of this view. Many philosophers (most notably, Tyler Burge) regard it as a prime example of a fruitful cognitive theory that widely individuates the representations it posits. I argue that, contrary to popular belief, Marr's theory does not presuppose an externalist view of mental content.

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.

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)

I argue that phenomenal externalism is preferable to phenomenal internalism on the basis of externalism's explanatory power with respect to qualitative character. I argue that external qualities, namely, external physical properties that are qualitative independent of consciousness, are necessary to explain qualitative character, and that phenomenal externalism is best understood as accepting external qualities while phenomenal internalism is best understood as rejecting them. I build support for the claim that external qualities are necessary to explain qualitative character (...) on the basis of a model of color perception as a certain sort of information filter by which perceivers gain access to external qualities.

This is a defence of externalism about knowledge and also about justification. In this paper, I argue that an important virtue of externalism about these notions is that externalism about justification helps to explain the value of (i.e., importance of) knowledge. I also develop and expand upon some of my earlier arguments for externalism that drew upon what's now known as 'morally loaded cases'. The virtue of externalism is that it's the only view that can (...) both allow for certain kinds of categorical normative requirements while also vindicating the idea that we ought to be guided by the beliefs that we ought to have. (Internalists either have to deny that we ought to be guided by the beliefs that we ought to have (which isn't very internalist!) or, failing that, revise our views about the existence of certain kinds of categorical requirements and tell us that we ought to be guided by our beliefs to do evil things (which isn't very nice!).).
