In this paper, I address one recent objection to Andy Clark and David Chalmers’s functionalist argument for the extended mind thesis. This objection is posed by Kengo Miyazono, who claims that they unjustifiably identify the original cognitive subject with the hybrid one in order to reach their conclusion about the mind extension. His attack consists of three steps: distinguishing hybrid from traditional cognitive subjects based on the systems reply originally directed at Searle’s Chinese room argument; pointing out that the conclusion (...) of the functionalist argument for EM must be rephrased to state that there are hybrid, and not extended, systems with widely realized mental states; and arguing that functionalist EM cannot justify the assumption about the identity of these two kinds of subjects without circularity. I argue that Miyazono’s main argument is ill-founded but that it, nevertheless, points out one important issue, namely, that we need further justification of the identity assumption, without which EM loses much of its flavor. Thus, I am going to challenge Miyazono’s argument, provide a reinterpretation of the argumentation in the EM debate, defend the possibility of wide and extended selves, and offer a justification of the identity assumption, which I find crucial not only for vindicating EM but also for differentiating EM from other similar theses, such as the thesis about group minds.

Concepts are highly theoretical entities. One cannot study them empirically without committing oneself to substantial preliminary assumptions. Among the competing theories of concepts and categorization developed by psychologists in the last thirty years, the implicit theoretical assumption that what falls under a concept is determined by description () has never been seriously challenged. I present a nondescriptionist theory of our most basic concepts, which include (1) stuffs (gold, milk), (2) real kinds (cat, chair), and (3) individuals (Mama, Bill Clinton, the (...) Empire State Building). On the basis of something important that all three have in common, our earliest and most basic concepts of substances are identical in structure. The membership of the category like that of is a natural unit in nature, to which the concept does something like pointing, and continues to point despite large changes in the properties the thinker represents the unit as having. For example, large changes can occur in the way a child identifies cats and the things it is willing to call without affecting the extension of its word The difficulty is to cash in the metaphor of in this context. Having substance concepts need not depend on knowing words, but language interacts with substance concepts, completely transforming the conceptual repertoire. I will discuss how public language plays a crucial role in both the acquisition of substance concepts and their completed structure. (shrink)

Realism about musical works is often tied to some type of Platonism. Nominalism, which posits that musical works exist and that they are concrete objects, goes with ontological realism much less often than Platonism: there is a long tradition which holds human-created objects (artifacts) to be mind-dependent. Musical Platonism leads to the well-known paradox of the impossibility of creating abstract objects, and so it has been suggested that only some form of nominalism becoming dominant in the ontology of art could (...) cause a great change in the field and open up new possibilities. This paper aims to develop a new metaontological view starting from the widely accepted claim that musical works are created. It contends that musical works must be concrete and created objects of some sort, but, nevertheless, they are mind-independent, and we should take the revisionary methodological stance. Although musical works are artifacts, what people think about them does not determine what musical works are. Musical works are similar to natural objects in the following sense: semantic externalism applies to the term ‘musical work’ because, firstly, they possess a shared nature, and, secondly, we can be mistaken about what they are.

What are biological species? Aristotelians and Lockeans agree that they are natural kinds; but, evolutionary theory shows that neither traditional philosophical approach is truly adequate. Recently, Michael Ghiselin and David Hull have argued that species are individuals. This claim is shown to be against the spirit of much modern biology. It is concluded that species are natural kinds of a sort, and that any 'objectivity' they possess comes from their being at the focus of a consilience of inductions.

In this paper I discuss a variant of the knowledge argument which is based upon Frank Jackson's Mary thought experiment. Using this argument, Jackson tries to support the thesis that a purely physical – or, put generally: an objectively scientific – perspective upon the world excludes the important domain of `phenomenal' facts, which are only accessible introspectively. Martine Nida-Rümelinhas formulated the epistemological challenge behind the case of Mary especially clearly. I take her formulation of the problem as a starting-point and (...) present a solution which is based solely on the concepts of capability and of metalinguistic beliefs. References to epiphenomenal facts, phenomenal knowledge etc. will be avoided completely. I specify my proposal against the backdrop of Burge's critical reflections about metalinguistic reinterpretation of expressions of belief and the externalist thesis held by Burge, Putnam and others that meanings and mental states are dependent upon the environment. My solution is then compared with Lewis' and Nemirow's ability objection. Finally I argue that the much discussed ``knowing what it is like'' has in its ordinary meaning nothing much to do with `phenomenal knowledge' or knowledge of `epiphenomenal' facts. (shrink)

Psychological essentialism is the belief that some internal, unseen essence or force determines the common outward appearances and behaviors of category members. We investigated whether reasoning about transplants of bodily elements showed evidence of essentialist thinking. Both Americans and Indians endorsed the possibility of transplants conferring donors' personality, behavior, and luck on recipients, consistent with essentialism. Respondents also endorsed essentialist effects even when denying that transplants would change a recipient's category membership (e.g., predicting that a recipient of a pig's heart (...) would act more pig-like but denying that the recipient would become a pig). This finding runs counter to predictions from the strongest version of the “minimalist” position (Strevens,2000), an alternative to essentialism. Finally, studies asking about a broader range of donor-to-recipient transfers indicated that Indians essentialized more types of transfers than Americans, but neither sample essentialized monetary transfer. This suggests that results from bodily transplant conditions reflect genuine essentialism rather than broader magical thinking. (shrink)

In this article I address the question of what makes addiction morally problematic, and seek to answer it by drawing on values salient in the sub-Saharan African philosophical tradition. Specifically, I appeal to life-force and communal relationship, each of which African philosophers have at times advanced as a foundational value, and spell out how addiction, or at least salient instances of it, could be viewed as unethical for flouting them. I do not seek to defend either vitality or community as (...) the best explanation of when and why addiction is immoral, instead arguing that each of these characteristically African values grounds an independent and plausible account of that. I conclude that both vitalism and communalism merit consideration as rivals to accounts that Western ethicists would typically make, according to which addiction is immoral insofar as it degrades rationality or autonomy, as per Kantianism, or causes pain or dissatisfaction, à la utilitarianism.

The “therapeutic obligation” is a physician’s duty to provide his patients with what he believes is the best available treatment. We begin by discussing some prominent formulations of the obligation before raising two related considerations against those formulations. First, they do not make sense of cases where doctors are permitted to provide suboptimal care. Second, they give incorrect results in cases where doctors are choosing treatments in challenging epistemic environments. We then propose and defend an account of the therapeutic obligation (...) that solves the problems that undermined previous efforts at formulating the TO. We conclude by considering how apparent problems with our proposal actually rest on difficulties with informed consent. (shrink)

This paper compares tracking and phenomenal intentionality theories of intentionality with respect to the issue of naturalism. Tracking theories explicitly aim to naturalize intentionality, while phenomenal intentionality theories generally do not. It might seem that considerations of naturalism count in favor of tracking theories. We survey key considerations relevant to this claim, including some motivations for and objections to the two kinds of theories. We conclude by suggesting that naturalistic considerations may in fact support phenomenal intentionality theories over tracking theories.

The paper discusses the problems raised by the inexactness of experiential concepts for a deductivist account of theoretical explanation. The process of theoretical explanation is explicated in terms of the devising of exact forms of inexact concepts. Analysis of the adjustments of concepts and their exact forms to each other reveals an implicit criterion of adequacy for theories which is related to the principle of connectivity.

Can physicalism (or materialism) be non-reductive? I provide an opinionated survey of the debate on this question. I suggest that attempts to formulate non-reductive physicalism by appeal to claims of event identity, supervenience, or realization have produced doctrines that fail either to be physicalist or to be non-reductive. Then I treat in more detail a recent attempt to formulate non-reductive physicalism by Derk Pereboom, but argue that it fares no better.

There is a fairly general consensus that names are Millian (or Russellian) genuine terms, that is, are singular terms whose sole semantic function is to introduce a referent into the propositions expressed by sentences containing the term. This answers the question as to what sort of proposition is expressed by use of sentences containing names. But there is a second serious semantic problem about proper names, that of how the referents of proper names are determined. This is the question that (...) I will discuss in this paper. Various views consistent with Millianism have been proposed as to how the semantic referents of proper names are determined. These views can be classified into (1) description theories and (2) causal theories, but they can also be classified into (3) social practice theories, on which a name’s referent is determined by a social practice involving the referent, and (4) individualistic theories, on which the referent of the use of a name is determined by the speaker’s state of mind. Here I argue against social practice theories of the sorts proposed by Kripke and Evans and in favor of an individualistic approach to name reference. I argue that social practice is irrelevant to determining name reference and that, as a consequence, names have no meanings in natural languages. In the second part of the paper I motivate and propose a new form of individualistic theory which incorporates features of both description theories and Evans’s social practice theory. (shrink)

Tyler Burge's (1979) famous thought experiment concerning 'arthritis' is commonly assumed to show that all ascriptions of content to beliefs and other attitudes are dependent for their truth upon facts about the agent's social and linguistic environment. It is also commonly claimed that Burge's argument shows that Putnam's (1975) result regarding natural kind terms applies to all general terms whatever, and hence shows that all such terms have wide meanings.1 But I wish to show here, first, that neither Burge's initial (...) thought experiment nor a second type of example that Burge describes supports either of these conclusions. Second, I will identify the proper conclusion to draw from Burge's discussion and show that this conclusion does not really pose a serious problem for individualism about the mental. And finally, I will argue that Burge's discussion does not in fact provide a conclusive reason for believing its proper conclusion. (shrink)

Husserl has finally begun to be recognized as the precursor of current interest in intentionality — the first to have a general theory of the role of mental representations in the philosophy of language and mind. As the first thinker to put directedness of mental representations at the center of his philosophy, he is also beginning to emerge as the father of current research in cognitive psychology and artificial intelligence.

Paraconsistent logics are characterized by rejection of ex falso quodlibet, the principle of explosion, which states that from a contradiction, anything can be derived. Strikingly these logics have found a wide range of application, despite the misgivings of philosophers as prominent as Lewis and Putnam. Such applications, I will argue, are of significant philosophical interest. They suggest ways to employ these logics in philosophical and scientific theories. To this end I will sketch out a ‘naturalized semantic dialetheism’ following Priest’s early (...) suggestion that the principles governing human natural language may well be inconsistent. There will be a significant deviation from Priest’s work, namely, the assumption of a broadly Chomskyan picture of semantics. This allows us to explain natural language inconsistency tolerance without commitment to contentious views in formal logic. (shrink)

In "The Meaning of 'Meaning'" Putnam argues, among other things, that "'meanings' just ain't in the head". Putnam's central arguments in favor of this conclusion are unsound. The arguments in question are the famous intra-world Twin Earth arguments, given on pages 223-227 of the article in question. Each of these arguments relies on a premise to the effect that this or that Twin Earth scenario is both logically possible and one in which certain individuals are in the same overall "psychological (...) [state] in the narrow sense". The problem is that none of the scenarios are as advertised; that is, none of them are logically possible situations in which the relevant individuals are in the same overall "psychological [state] in the narrow sense".

In this paper, I present a new (i.e., previously overlooked) breed of exercitive speech act (the conversational exercitive). I establish that any conversational contribution that invokes a rule of accommodation changes the bounds of conversational permissibility and is therefore an (indirect) exercitive speech act. Such utterances enact permissibility facts without expressing the content of such facts, without the speaker intending to be enacting such facts and without the hearer recognizing that it is so. Because of the peculiar nature ofthe rules (...) of accommodation that generate them, conversational exercitives have importantly different felicity conditions and therefore constitute a new breed ofexercitive speech act.

This paper is ambitious: it begins with mixing externalism in philosophy of mind with internalism in epistemology, and it ends with instructive insights from social and feminist thought. In the first stage, I argue that one can consistently combine two theses that appear, at first glance, incompatible: cognitive externalism—the thesis that one’s mental states/processing can extend past one’s biological boundaries—and mentalism in epistemology—i.e., that epistemic justification supervenes on one’s mental states. This yields the perhaps startling or strange view that the (...) loci of epistemic justification are both mental states and located externally to one’s skull and skin. This motivates the second stage: I aim to ease that strangeness by suggesting that most discussions of cognitive externalism and epistemology too often focus exclusively on extending epistemically reliable abilities, faculties, dispositions, etc. to artifacts in one’s environment. Instead, we should think of this combination as informed by feminist epistemologists’ insistence of our thinking’s irreducible and radical sociality. Epistemic communities shape and are shaped by our cognition—echoing the dynamic, interactive integration at the heart of cognitive externalism. Thus, just as I am part of an epistemic community, it is also a part of me. Thus, I think with others: not merely as an artifact but as constituent elements of my cognition itself; resulting in a robust socially extended internalism. (shrink)

Three interrelated communicative issues emerge from recent U.S. political discourse in the wake of Donald Trump’s campaign for and election to the presidency. TRUTH figures prominently in social commentary on language. Semantically, truth relates to applicability conditions for linguistic expressions, which change and can be contested. Pragmatically, truth affects updating participants’ changing public commitments to what the world is like and to their own and others’ future actions. Updating as the speaker wants requires TRUST. Taking speakers as personally credible is (...) heavily tied to social identities and power relations. Experts and other “authorities” are often automatically accorded credibility but sometimes wrongly shielded from criticism. Disdain for expertise fueled Trump’s campaign and the social divides it exploited, continuing during his presidency. Although TRUMPERY (orig., “deceit, fraud”) is not confined to Trump or Trumpists, they are consummate practitioners. Communicative trumpery exploits “confirmation bias,” desires, and assumptions producing beliefs. It also arises from shifting interpretations and is key to evade communicative accountability (“just joking,” “a figure of speech”) or from refusing to engage with other discourse participants.

Davidson and Burge have claimed that the conditions under which self-knowledge is possessed are such that externalism poses no obstacle to their being met by ordinary speakers and thinkers. On their accounts. no such person could fail to possess self-knowledge. But we do from time to time attribute to each other such failures; so we should prefer to their accounts an account that preserves first person authority while allowing us to make sense of what appear to be true attributions of (...) such failures.While the core idea behind Davidson’s and Burge’s accounts appears inadequate to this task, I argue that it can be deployed in such a way as to deliver the desired result. What makes this possible is that two attitude-types can differ as follows: the self-knowledge required for an utterance to be a Φing that p is different from the self-knowledge required for it to be a Ψing that p.

The use of conventional logical connectives either in logic, in mathematics, or in both cannot determine the meanings of those connectives. This is because every model of full conventional set theory can be extended conservatively to a model of intuitionistic set plus class theory, a model in which the meanings of the connectives are decidedly intuitionistic and nonconventional. The reasoning for this conclusion is acceptable to both intuitionistic and classical mathematicians. En route, I take a detour to prove that, given (...) strictly intuitionistic principles, classical negation cannot exist. (shrink)

The role of intuition in Kripke's arguments for the causal-historical theory of reference has been a topic of recent debate, particularly in light of empirical work on these intuitions. In this paper, I develop three interpretations of the role intuition might play in Kripke's arguments. The first aim of this exercise is to help clarify the options available to interpreters of Kripke, and the consequences for the experimental investigation of Kripkean intuitions. The second aim is to show that understanding the (...) role of intuition in Kripke's arguments, and in other arguments commonly interpreted as ?appeals to intuition? requires that we pay careful attention to the argumentative context and theoretical commitments of the work in question. The interpretations of Kripke developed here provide a set of options which might be adapted to other arguments to help clarify what role (if any) intuition plays. (shrink)

The Socratic elenchus is a method of philosophical analysis which Plato largely dropped in his middle and later writings, with two exceptions, Republic 1 and the Theaetetus. But it is a mistake to describe these as elenctic dialogues, which typically seek an analysis of a virtue in terms of necessary and sufficient conditions, by questioning some alleged expert about its essence. Republic 1 does not follow this pattern: Thrasymachus fundamentally objects to such a procedure and the presuppositions underlying it, while (...) Glaucon and Socrates turn to developing their own theories of justice. The Theaetetus is likewise concerned with exploring and testing theories, in this case of knowledge. The Socratic elenchus cannot produce any philosophically interesting theories, let alone establish their truth, but at most refute them. As Plato increasingly sought out such theories, the kind of analysis at issue in the Socratic elenchus came to interest him less. (shrink)

In his 1975 paper “The Meaning of ‘Meaning’”, Hilary Putnam famously argued for semantic externalism. Little attention has been paid, however, to the fact that already in 1973, Putnam had presented the idea of the linguistic division of labor and the Twin Earth thought experiment in his comment on Wilfrid Sellars’s “Meaning as Functional Classification” at a conference, and Sellars had replied to Putnam from a broadly inferentialist perspective. The first half of this paper aims to trace the development of (...) Putnam’s semantic externalism, situate his debate with Sellars in it, and reconstruct the two arguments he presented against Sellars. The second half of this paper aims to reconstruct how Sellars replied to Putnam. I argue that Sellars not only accepts the social character of language but also suggests how inferentialists can accommodate the contribution of the world. Sellars’s key idea is that substance terms have a “promissory note aspect” which is to be cashed out in a successor conceptual framework. I reconstruct Sellars’s position as ideal successor externalism, and compare it with temporal externalism. (shrink)

In recent years attacks on the Kripke-Putnam approach to natural kinds and natural kind terms have proliferated. In a recent paper, Häggqvist and Wikforss (The British Journal for the Philosophy of Science, 1–23, 2017) attack the once-dominant essentialist account of natural kinds. Häggqvist & Wikforss also suggest that it is time to return to some sort of cluster-based descriptivist semantics for natural kind terms, thus targeting both the metaphysical and semantic tenets that underpin the Kripke-Putnam approach. In our paper we (...) want to challenge both parts of Häggqvist and Wikforss’ project. We will argue that the anti-essentialist considerations and arguments they raise against the Kripke-Putnam view are far from compelling in some cases, and certainly not decisive against a reasonable form of the view. On the semantic side, although Häggqvist and Wikforss give few details about what a viable cluster-based descriptivist theory should look like, we will argue that one can already see the approach to be a non-starter. Ignorance and error arguments of the kinds provided by Kripke and Putnam continue to be decisive objections. The only way we can see to save the cluster descriptivist approach is to make the essential properties postulated by Kripke and Putnam become essential features of the descriptive cluster. But this makes the success of the approach parasitic on the correctness of the Kripke-Putnam view. (shrink)

Many psychologists think that concepts should be understood on analogy with the terms of scientific theories, yet the significance of this claim has always been obscure. In this paper, I clarify the psychological content of the theory analogy, focusing on influential pieces by Susan Carey. Once plainly put, the analogy amounts to the view that a mental representation has its semantic properties by virtue of its role in a restricted knowledge structure. One of the commendable things about Carey's work is (...) that, unlike many other psychologists who appeal to the theory analogy, she takes seriously the need to specify how these structures are constrained. At the same time, the constraints she offers are insufficient. Her account also faces challenges from work in the semantics of natural kind terms. (shrink)

Externalism about artifactual words requires that (a) members of an artifactual word’s extension share a common nature, i.e. a set of necessary features, and (b) that possession of such features determines the word’s extension independently of whether the linguistic community is aware of them (ignorance) or can accurately describe them (error). However, many common artifactual words appear to be so used that features that are universally shared among members of their extensions are hard to come by, and even fewer can (...) be plausibly regarded as necessary; morevoer, it is highly doubtful that a speaker could manage to refer to kind A while being utterly ignorant of the role the As play in the A-producing community, and it is no less doubtful that an artifactual word that was used to refer to certain objects would keep referring to them (and be regarded as having referred to them) once it has been shown that the associated description is utterly false of such objects, the reason being that we could easily make things that do fit the associated description. Against generalized externalism, it is suggested that artifactual words come in (at least) three different semantic varieties: a few have an externalist semantics, others have an internalist semantics, still others have neither but rather behave as “family names” in Wittgenstein’s sense.

This paper argues that Malebranche’s semantics sheds light on his metaphysics and epistemology, and is of interest in its own right. By recasting issues linguistically, it shows that Malebranche assumes a Neoplatonic semantic structure within Descartes’ dualism and Augustine’s theory of illumination, and employs linguistic devices from the Neoplatonic tradition. Viewed semantically, mental states of illumination stand to God and his ideas as predicates stand in Neoplatonic semantics to ideas ordered by a privative relation on “being.” The framework sheds light (...) on interpretive puzzles in Malebranche studies such as the way ideas reside in God’s mind, the notion of resemblance by which bodies imitate their exemplar causes, and the issue of direct vs. indirect perception through a mechanism by which agents can see bodies by “seeing” ideas. Malebranche’s semantics is of interest in its own right because it gives a full account of the mediating relations that determine indirect reference; lays out a correspondence theory of truth for necessary judgments; defines contingent truth as based on an indirect reference relation that is both descriptive and causal but that does not appeal to body-mind causation; and within his theory of perception, works out an account of singular reference in which singular terms carry existential import, refer indirectly via causal relations, but describe their referents only in a general way.

We undertake to bring a phenomenological perspective to bear on a challenge of contemporary law and clinical practice. In a wide variety of contexts, legal and medical professionals are called upon to assess the competence or capacity of an individual to exercise her own judgement in making a decision for herself. We focus on decisions regarding consent to or refusal of medical treatment and contrast a widely recognised clinical instrument, the MacCAT-T, with a more phenomenologically informed approach. While the MacCAT-T (...) focuses attention on individual cognitive performance criteria, an approach oriented by second-person phenomenology brings into view the complex role of time, others and identity in constituting the capacity for individual autonomous judgement. Our phenomenological analysis has consequences both for the practice of capacity assessments and for further research in this arena. Good practice in capacity assessment must attend to decision communities, distributed capacity, and temporal competence, while research on mental capacity will miss the phenomenon if it trains its focus ‘between the ears.’ We illustrate our approach by considering two recent cases of contested capacity: one involving cognitive disability in a dysfunctional decision community, the second presenting the possibility of competent decision-making under conditions of paranoid schizophrenia.

In this paper, I develop a novel account of concept acquisition for an atomistic theory of concepts. Conceptual atomism is rarely explored in cognitive science because of the feeling that atomistic treatments of concepts are inherently nativistic. My model illustrates, on the contrary, that atomism does not preclude the learning of a concept.

This paper proposes a response to the duplication objection to the descriptive theory of singular mental reference. This objection involves hypothetical cases in each of which there are a pair of qualitatively indistinguishable objects and a thought that apparently refers to only one of the pair, despite the descriptive indistinguishability of the two objects. I identify a concept of reference-likeness or closeness to reference, which is related to the concept of genuine singular reference as the concept of truthlikeness or closeness (...) to truth is related to the concept of truth. My response to the duplication objection is to say that the hypothetical cases it involves establish only that a thought can come close enough to singular reference to a thing despite not genuinely referring to that thing, a consequence that is compatible with the descriptive theory of singular mental reference.

A standard view within psychology is that there have been two important shifts in the study of concepts and that each has led to some improvements. The first shift was from the classical theory of concepts to probabilistic theories, including the prototype theory. The second shift was from probabilistic theories to theory-based theories. In this article, I critically evaluate the view that the first shift was a major advance and argue that the prototype theory suffers some of the same problems (...) that have been thought to challenge the classical theory.

This paper argues for a conditional claim concerning a famous argument—developed by Church in elucidation of some remarks by Frege to the effect that the bedeutung of a sentence is the sentence’s truth-value—the Frege–Gödel–Church argument, or FGC for short. The point we make is this :if, and just to the extent that, Arthur Smullyan’s argument against Quine's use of FGC is sound, then essentially the same rejoinder disposes also of Davidson's use of FGC against ‘correspondence’ theories of truth. We thus (...) dispute a contention by Professor Davidson that it is coherent to accept that Smullyan’s rejoinder takes away the force of Quine’s version of FGC, while still consistently using FGC to establish that if true sentences (or utterances) correspond to anything, they all correspond to the same thing. We show that the differences between the cases discussed by Smullyan and Davidson’s version of FGC on which Davidson relies for his contention are irrelevant to the point under dispute. (shrink)

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

This paper raises concern with the use of theories of reference in philosophical discourse and then to consider the possibility of empirically validating this concern by reference to a novel sort of “quantitative” empirical approach suggested recently by Shaun Nichols (forthcoming). The concern is whether the particular theories of reference or reference relations employed in particular philosophical discussions are actually chosen with a view to entailing or accommodating a desired philosophical outcome. I argue that such dependent selections of assumptions about (...) reference give us little reason to think the assumptions are true. I go on to argue that if we became convinced that such assumptions really are chosen simply to ensure a desired outcome, it would give us reason for skepticism about arguments from reference since it would undermine our sense that such arguments tracked any independent truth about the reference of our words or concepts. (shrink)

We tend to think that our concepts are stable in the sense that, whilst their extensions may vary across distinct epistemic scenarios, the reference-fixing conditions by which we discover these extensions remain fixed. This paper challenges this orthodoxy. In particular, it aims to motivate the position that some concepts are unstable in that their reference-fixing conditions themselves vary across distinct epistemic scenarios. Furthermore, it aims to draw out the implications such instability has for epistemic possibility and apriority. I shall argue (...) that when unstable concepts are concerned epistemic space will be widened, which in turn will restrict our a priori knowledge; and in ways that might be salient to solving certain familiar philosophical problems.

Roy Sorensen advances an evolutionary explanation of our capacity for thought experiments which doubles as a naturalized epistemological justification. I argue Sorensens explanation fails to satisfy key elements of environmental-selectionist explanations and so fails to carry epistemic force. I then argue that even if Sorensen succeeds in showing the adaptive utility of our capacity, he still fails to establish its reliability and hence epistemic utility. I conclude Sorensens account comes to little more than a just-so story.

The paper offers a new understanding of induction in the empirical sciences, one which assimilates it to induction in geometry rather than to statistical inference. To make the point a system of notions, essential to logically sound induction, is defined. Notable among them are arbitrary object and particular property. A second aim of the paper is to bring to light a largely neglected set of assumptions shared by both induction and deduction in the empirical sciences. This is made possible by (...) appealing to the logic of common nouns and applying it to the logic of natural-kind terms.This strategy yields a new insight into the concept of natural kinds. While the strategy reveals deep affinity between empirical induction and deduction it also reveals two problems peculiar to induction. This helps to explain the intuition that induction is the more problematic of the two. The paper does not set out ‘to solve the problem of induction’. 1The paper has benefited from the support and critical comments of several friends: Steven Davis, Kevin Dunbar, Anil Gupta, Michael Hallett, Ray Jackendoff and Storrs McCall. Two friends, however, deserve special thanks, Michael Makkai and Gonzalo Reyes. Many of the points made in the paper, otherwise unacknowledged, are due to their generosity and patience. In fact, the paper can be seen as an application of the logic of kinds on which Gonzalo Reyes has been working for several years. (shrink)

Theories of reference have been central to analytic philosophy, and two views, the descriptivist view of reference and the causal-historical view of reference, have dominated the field. In this research tradition, theories of reference are assessed by consulting one’s intuitions about the reference of terms in hypothetical situations. However, recent work in cultural psychology (e.g., Nisbett et al. 2001) has shown systematic cognitive differences between East Asians and Westerners, and some work indicates that this extends to intuitions about philosophical cases (...) (Weinberg et al. 2001). In light of these findings on cultural differences, two experiments were conducted which explored intuitions about reference in Westerners and East Asians. Both experiments indicate that, for certain central cases, Westerners are more likely than East Asians to report intuitions that are consistent with the causal-historical view. These results constitute prima facie evidence that semantic intuitions vary from culture to culture, and the paper argues that this fact raises questions about the nature of the philosophical enterprise of developing a theory of reference.

Although cognitive scientists have learned a lot about concepts, their findings have yet to be organized in a coherent theoretical framework. In addition, after twenty years of controversy, there is little sign that philosophers and psychologists are converging toward an agreement about the very nature of concepts. Doing without Concepts (Machery 2009) attempts to remedy this state of affairs. In this article, I review the main points and arguments developed at greater length in Doing without Concepts.

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.

In this paper I examine whether representationalism can account for various thought experiments about colour inversions. Representationalism is, at minimum, the view that, necessarily, if two experiences have the same representational content then they have the same phenomenal character. I argue that representationalism ought to be rejected if one holds externalist views about experiential content and one holds traditional exter- nalist views about the nature of the content of propositional attitudes. Thus, colour inver- sion scenarios are more damaging to externalist (...) representationalist views than have been previously thought. More specifically, I argue that representationalists who endorse externalism about experiential content either have to become internalists about the content of propositional attitudes or they have to adopt a novel variety of externalism about the content of propositional attitudes. This novel type of propositional attitude externalism is investigated. It can be seen that adopting it forces one to reject Putnam. (shrink)
