Experimental philosophers often seem to ignore or downplay the significance of demographic variation in philosophically relevant judgments. This article confirms this impression, discusses why demographic research is overlooked in experimental philosophy, and argues that variation is philosophically significant.

Carey holds that the study of conceptual development bears on the theories of concepts developed by philosophers and psychologists. In this commentary, I scrutinize her claims about the significance of the study of conceptual development.

In this article, I argue that philosophers’ intuitions about reference are not more reliable than lay people’s and that intuitions about the reference of proper names and uses of proper names provide equally good evidence for theories of reference.

In this précis, I review the main points and arguments developed at greater length in Doing without Concepts, and I explain why eliminating the notion of concept would contribute to the progress of the psychology of higher cognition.

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.

Machery et al. (2004) reported some preliminary evidence that intuitions about reference vary within and across cultures, and they argued that if real, such variation would have significant philosophical implications (see also Mallon et al. 2009). In a recent article, Genoveva Martı´ (2009) argues that the type of intuitions examined by Machery and colleagues (‘metalin- 10 guistic intuitions’) is evidentially irrelevant for identifying the correct theory of reference, and she concludes that the variation in the relevant intuitions about reference within (...) and across cultures has not been established.

We have recently presented evidence for cross-cultural variation in semantic intuitions and explored the implications of such variation for philosophical arguments that appeal to some theory of reference as a premise. Devitt (2011) and Ichikawa and colleagues (forthcoming) offer critical discussions of the experiment and the conclusions that can be drawn from it. In this response, we reiterate and clarify what we are really arguing for, and we show that most of Devitt’s and Ichikawa and colleagues’ criticisms fail to address (...) our concerns. (shrink)

Elimination controversies are ubiquitous in philosophy and the human sciences. For example, it has been suggested that human races, hysteria, intelligence, mental disorder, propositional attitudes such as beliefs and desires, the self, and the super-ego should be eliminated from the list of respectable entities in the human sciences. I argue that eliminativist proposals are often presented in the framework of an oversimplified “phlogiston model” and suggest an alternative account that describes ontological elimination on a gradual scale between criticism of empirical (...) assumptions and conceptual choices.

The aim of this article is to develop an argument against metaphysical debates about the existence of human races. I argue that the ontology of race is underdetermined by both empirical and non-empirical evidence due to a plurality of equally permissible candidate meanings of "race." Furthermore, I argue that this underdetermination leads to a deflationist diagnosis according to #hich disputes about the existence of human races are non-substantive verbal disputes. $hile this diagnosis resembles general deflationist strategies in contemporary metaphysics" I (...) show that my argument does not presuppose controversial metametaphysical assumptions. (shrink)

In the essay, I compare the aims and especially the methods of philosophers and grammarians. It transpires that there are several interesting similarities to be found with the method and aim in particular of traditional 'armchair philosophers'. I argue that these similarities go far enough to suggest that if armchair philosophers' method is in a state of challenge, as is claimed by a number of experimental philosophers, then the same can be said about the method of grammarians. However, I also (...) try to show that it is not easy for experimental philosophers to frame their critique in a way that avoids construing its target too broadly, which would lead to unacceptable consequences. I conclude with some brief remarks on the extent to which a properly targeted critique can provide a challenge for traditional philosophical method. (shrink)

Machery et al. claim that analytic philosophers of language are committed to a method of cases according to which theories of reference are assessed by consulting semantic intuitions about actual and possible cases. Since empirical evidence suggests that such intuitions vary both within and across cultures, these experimental semanticists conclude that the traditional attempt at pursuing such theories is misguided. Against the backdrop of Kripke’s anti-descriptivist arguments, this paper offers a novel response to the challenge posed by Machery et al., (...) arguing that they either misplace or exaggerate the role played by. The lesson is that while semantic intuitions carry evidential weight in evaluating certain subjunctive conditionals reflecting counterfactual possibilities, they neither play an epistemic role in determining the actual reference of proper names, nor in evaluating certain indicative conditionals reflecting so-called counteractual possibilities. Moreover, once an asymmetry is acknowledged in Machery et al’s vignette between the narrator and the subject’s suppositions about the actual world, a corresponding ambiguity can account for the alleged culturally determined variation in semantic intuitions. (shrink)

Sentences in context have semantic contents determined by a range of factors both internal and external to speakers. I argue against the thesis that semantic content is transparent to speakers in the sense of being immediately accessible to speakers in virtue of their linguistic competence.

In this paper I defend anti-realism about race and a new theory of racialization. I argue that there are no races, only racialized groups. Many social constructionists about race have adopted racial formation theory to explain how ‘races’ are formed. However, anti-realists about race cannot adopt racial formation theory, because it assumes the reality of race. I introduce interactive constructionism about racialized groups as a theory of racialization for anti-realists about race. Interactive constructionism moves the discussion away from the dichotomous (...) (social vs. biological) metaphysics that has marred this debate, and posits that racialized groups are the joint products of a broad range of non-racial factors, which interact. (shrink)

The biological race debate is at an impasse. Issues surrounding hereditarianism aside, there is little empirical disagreement left between race naturalists and anti-realists about biological race. The disagreement is now primarily semantic. This would seem to uniquely qualify philosophers to contribute to the biological race debate. However, philosophers of race are reluctant to focus on semantics, largely because of their worries about the ‘flight to reference’. In this paper, I show how philosophers can contribute to the debate without taking the (...) flight to reference. Drawing on the theory of reference literature and the history of meaning change in science, I develop some criteria for dealing with cases where there is uncertainty about reference. I then apply these criteria to the biological race debate. All of the criteria I develop for eliminating putative kinds are met in the case of ‘race’ as understood by twentieth century geneticist Theodosius Dobzhansky and his contemporary proponents, suggesting that we should eliminate it from our biological ontology.

Some years ago, Machery, Mallon, Nichols, and Stich reported the results of experiments that reveal, they claim, cross-cultural differences in speaker’s ‘intuitions’ about Kripke’s famous Gödel–Schmidt case. Several authors have suggested, however, that the question they asked their subjects is ambiguous between speaker’s reference and semantic reference. Machery and colleagues have since made a number of replies. It is argued here that these are ineffective. The larger lesson, however, concerns the role that first-order philosophy should, and more importantly should not, (...) play in the design of such experiments and in the evaluation of their results.

This paper defends a challenge, inspired by arguments drawn from contemporary ordinary language philosophy and grounded in experimental data, to certain forms of standard philosophical practice. The challenge is inspired by contemporary philosophers who describe themselves as practicing “ordinary language philosophy”. Contemporary ordinary language philosophy can be divided into constructive and critical approaches. The critical approach to contemporary ordinary language philosophy has been forcefully developed by Avner Baz, who attempts to show that a substantial chunk of contemporary philosophy is fundamentally (...) misguided. I describe Baz’s project and argue that while there is reason to be skeptical of its radical conclusion, it conveys an important truth about discontinuities between ordinary uses of philosophically significant expressions (“know”, e.g.) and their use in philosophical thought experiments. I discuss some evidence from experimental psychology and behavioral economics indicating that there is a risk of overlooking important aspects of meaning or misinterpreting experimental results by focusing only on abstract experimental scenarios, rather than employing more diverse and more ecologically valid experimental designs. I conclude by presenting a revised version of the critical argument from ordinary language. (shrink)

Experimental philosophy of language uses experimental methods developed in the cognitive sciences to investigate topics of interest to philosophers of language. This article describes the methodological background for the development of experimental approaches to topics in philosophy of language, distinguishes negative and positive projects in experimental philosophy of language, and evaluates experimental work on the reference of proper names and natural kind terms. The reliability of expert judgments vs. the judgments of ordinary speakers, the role that ambiguity plays in influencing (...) responses to experiments, and the reliability of metalinguistic judgments are also assessed.

Robert Kraut has proposed an analogy between valuing a loved one as irreplaceable and the sort of “rigid” attachment that (according to Saul Kripke’s account) occurs with the reference of proper names. We wanted to see if individuals with Kripkean intuitions were indeed more likely to value loved ones (and other persons and things) as irreplaceable. In this empirical study, 162 participants completed an online questionnaire asking them to consider how appropriate it would be to feel the same way about (...) a perfect replica of a loved one, as well as other questions about replaceability. Participants who previously had endorsed Kripkean reference (n = 96) rated loved ones as less replaceable on two different measures than participants who had previously endorsed Descriptivist reference (n = 66, t(160)> 2.27, p <.02, eta2> .03). Additional results suggest that this difference extends to other targets as well and is at least partially dependent on sentimental attachment. (shrink)

We argue that current discussions of criteria for actual causation are ill-posed in several respects. (1) The methodology of current discussions is by induction from intuitions about an infinitesimal fraction of the possible examples and counterexamples; (2) cases with larger numbers of causes generate novel puzzles; (3) "neuron" and causal Bayes net diagrams are, as deployed in discussions of actual causation, almost always ambiguous; (4) actual causation is (intuitively) relative to an initial system state since state changes are relevant, but (...) most current accounts ignore state changes through time; (5) more generally, there is no reason to think that philosophical judgements about these sorts of cases are normative; but (6) there is a dearth of relevant psychological research that bears on whether various philosophical accounts are descriptive. Our skepticism is not directed towards the possibility of a correct account of actual causation; rather, we argue that standard methods will not lead to such an account. A different approach is required. (shrink)

In recent years, experimental philosophers have questioned the reliance of philosophical arguments on intuitions elicited by thought experiments. These challenges seek to undermine the use of this methodology for a particular domain of theorizing, and in some cases to raise doubts about the viability of philosophical work in the domain in question. The topic of semantic reference has been an important area for discussion of these issues, one in which critics of the reliance on intuitions have made particularly strong claims (...) about the prospects for philosophical theories of reference and arguments based on claims about reference. In this article, I review the main lines of argument in this area of experimental philosophy, with particular emphasis on the relevance of empirical data about intuitions to philosophical views. I argue that although traditional philosophical theorizing about reference faces little threat from experimental data about intuitions, there is nevertheless much to be gained from collecting and analyzing such data, which holds the promise of greatly enriching our conception of the mechanisms governing judgments about semantic reference in ways that are highly relevant to philosophers. (shrink)

Contemporary debates about the nature of semantic reference have tended to focus on two competing approaches: theories which emphasize the importance of descriptive information associated with a referring term, and those which emphasize causal facts about the conditions under which the use of the term originated and was passed on. Recent empirical work by Machery and colleagues suggests that both causal and descriptive information can play a role in judgments about the reference of proper names, with findings of cross-cultural variation (...) in judgments that imply differences between individuals with respect to whether they favor causal or descriptive information in making reference judgments. We extend this theoretical and empirical line of inquiry to views of the reference of natural and nominal kind concepts, which face similar challenges to those concerning the reference of proper names. In two experiments, we find evidence that both descriptive and causal factors contribute to judgments of concept reference, with no reliable differences between natural and nominal kinds. Moreover, we find evidence that the same individuals’ judgments can rely on both descriptive and causal information, such that variation between individuals cannot be explained by appeal to a mixed population of “pure descriptive theorists” and “pure causal theorists.” These findings suggest that the contrast between descriptive and causal theories of reference may be inappropriate; intuitions may instead support a hybrid theory of reference that includes both causal and descriptive factors. We propose that future research should focus on the relationship between these factors, and describe several possible frameworks for pursuing these issues. Our findings have implications for theories of semantic reference, as well as for theories of conceptual structure. (shrink)

This paper considers three package deals combining views in philosophy of mind, meta-philosophy, and experimental philosophy. The most familiar of these packages gives center-stage to pumping intuitions about fanciful cases, but that package involves problematic commitments both to a controversial descriptivist theory of reference and to intuitions that “negative” experimental philosophers have shown to be suspiciously variable and context-sensitive. In light of these difficulties, it would be good for future-minded experimental philosophers to align themselves with a different package deal. This (...) paper suggests two alternatives. Experimentalists might help fans of “naturalized” approaches discover what natural kinds have been playing an appropriate role in causing us to use concepts as we do. Or, better still, experimentalists might instead help pragmatists and teleo-semanticists discover how our concept usage regularly yields beneficial outcomes, so that we can then craft philosophical analyses that will..

This article is in three parts. The first discusses trends in philosophy. The second defends reliance on intuitions in philosophy from some doubts that have recently been raised. The third discusses Philip Kitcher's contention that contemporary analytic philosophy does not have its priorities straight. While the three parts are independent, there is a common theme. Each part defends what is regarded as orthodoxy from attacks. Of course there are other reasonable challenges to philosophical methodology. The article's aim is just to (...) respond to some charges that have been made. (shrink)

The article is an extended critical discussion of Kevin Scharp’s Replacing Truth. Scharp’s case for the claim that the concept of truth is inconsistent is criticized, and so is his case for the claim that the concept of truth must be replaced because of its inconsistency.

The main goal of the paper is to propose a methodology for the theory of reference in which experiments feature prominently. These experiments should primarily test linguistic usage rather than the folk’s referential intuitions. The proposed methodology urges the use of: (A) philosophers’ referential intuitions, both informally and, occasionally, scientifically gathered; (B) the corpus, both informally and scientifically gathered; (C) elicited production; and, occasionally,_ _(D) folk’s referential intuitions. The most novel part of this is (C) and that is where most (...) of the experimental work should be. The secondary goal of the paper is to defend my earlier paper “Experimental Semantics” from the criticisms of Machery, Mallon, Nichols, and Stich in “If Folk Intuitions Vary, Then What?” They charge that I have seriously misunderstood their goal in “Semantics, Cross-Cultural Style” and that many of my arguments are “largely irrelevant”. I argue that these charges are baseless. (shrink)

It is argued on a variety of grounds that recent results in 'experimental philosophy of language', which appear to show that there are significant cross-cultural differences in intuitions about the reference of proper names, do not pose a threat to a more traditional mode of philosophizing about reference. Some of these same grounds justify a complaint about experimental philosophy as a whole.

In this chapter I lay out a notion of philosophical naturalism that aligns with pragmatism. It is developed and illustrated by a presentation of my views on natural kinds and my theory of concepts. Both accounts reflect a methodological naturalism and are defended not by way of metaphysical considerations, but in terms of their philosophical fruitfulness. A core theme is that the epistemic interests of scientists have to be taken into account by any naturalistic philosophy of science in general, and (...) any account of natural kinds and scientific concepts in particular. I conclude with general methodological remarks on how to develop and defend philosophical notions without using intuitions. (shrink)

A popular rejoinder to the potential threat that incommensurability might pose to scientific realism has been the referential response: despite meaning variance, there can be referential continuity, which is sufficient for rational theory choice. This response has been charged with meta-incommensurability, according to which it begs the question by assuming realist metaphysics. However, realists take it to be a rhetorical device that hinders productive discussion. By reconstructing the debate, this paper aims to demonstrate two things. First, there are unexpected commonalities (...) between realists and non-realists, meaning that the charge of meta-incommensurability is more or less exaggerated. Second, meta-incommensurability, which is to be found in the ways to make sense of referential overlap at the token level, still plays a role in the realism debate. (shrink)

This entry addresses the nature and epistemological role of intuition by considering the following questions: (1) What are intuitions?, (2) What roles do they serve in philosophical (and other “armchair”) inquiry?, (3) Ought they serve such roles?, (4) What are the implications of the empirical investigation of intuitions for their proper roles?, and (5) What is the content of intuitions prompted by the consideration of hypothetical cases?

I will argue that the scientific investigation of philosophical intuition ('experimental philosophy') is of philosophical interest. I will defend the significance of experimental philosophy against two important types of objection. I will term the first objection 'eliminativism' about intuitions: roughly, it is the claim that philosophical methodology does not in fact rely on intuition, and thus experimental philosophy's investigation is ill-conceived—in the words of one such opponent, 'a big mistake.' I will then consider a second objection, the 'expertise' defence. The (...) expertise defence argues that the expert intuitions of professional philosophers are distinct, and to be preferred to those of the 'folk.' Against the eliminativists, I will argue that an ineliminable mental component remains that can be subject of fruitful empirical investigation. Against the expertise defence I will argue that, at least in the context of philosophy of language, expertise is itself a potential source of bias. Since expertise is domain-specific, however, a general rebuttal will not be given. I will conclude that experimental philosophy has much to contribute. (shrink)

The choice between realism and instrumentalism is at the core of concerns about how our scientific models relate to reality: Do our models aim to be literally true descriptions of reality, or is their role only as useful instruments for generating predictions? Realism about X, roughly speaking, is the claim that X exists and has its nature independent of our interests, attitudes, and beliefs. An instrumentalist about X denies this. She claims that talk of X should be understood as no (...) more than a useful locution for generating predictions, such talk should not be understood as taking on a commitment to the existence of X. According to an instrumentalist, we should either flatly not believe that X is out there, or else suspend judgement about the existence of X. The most we need acknowledge is that talk of X is useful in making predictions. The question of realism vs. instrumentalism can be asked about almost any theoretical entity in science. It is likely, and seems reasonable, that different answers will be given in different cases. Someone may wish to be a realist about certain theoretical entities (e.g. electrons), but an instrumentalist about others (e.g. centres of gravity). Not every noun-phrase in a scientific theory should be taken as expressing an ontological commitment. Psychological theories are no exception. Almost every theoretical posit in psychology has been questioned as to whether it is really out there or just a useful theoretical fiction. In this entry, I will focus on two major theoretical posits in psychology: (a) propositional attitudes (e.g. beliefs, desires) and (b) conscious states (qualia). (shrink)

One of the more visible recent developments in philosophical methodology is the experimental philosophy movement. On its surface, the experimentalist challenge looks like a dramatic threat to the apriority of philosophy; ‘experimentalist’ is nearly antonymic with ‘aprioristic’. This appearance, I suggest, is misleading; the experimentalist critique is entirely unrelated to questions about the apriority of philosophical investigation. There are many reasons to resist the skeptical conclusions of negative experimental philosophers; but even if they are granted—even if the experimentalists are right (...) to claim that we must do much more careful laboratory work in order legitimately to be confident in our philosophical judgments— the apriority of philosophy is unimpugned. The kinds of scientific investigation that experimental philosophers argue to be necessary involve merely enabling sensory experiences. Although they are not enabling in the sense of permitting concept acquisition, they are enabling in another epistemically significant way that is also consistent with the apriority of philosophy.

I develop and argue for a novel theory of the mental state of identity confusion. I also argue that this mental state can corrupt the proper function of singular terms in linguistic communication. Finally, I propose a theory according to which identity confusion should be treated as a the source of a new sort of linguistic performance error, similar to malapropism, slips of the tongue, and so-called intentional obfuscation (inducing false belief by manipulating language in specific ways). -/- Going into (...) a bit more detail, I start by arguing that contemporary analytic philosophy, and philosophy of language in particular, has been dominated by a ‘puzzle-driven’ methodology. This tradition, I claim, seeks to provide a coherent system for describing semantic features of all conceivable cases where a speaker is confused about the identity or distinctness of an object. On my view, identity confusion is a mental state of an agent who either believes falsely that a is identical to b or believes falsely that a is not identical to b. I show how many influential arguments in philosophy – e.g., Kripke on semantic reference and speaker’s reference – are invalidated because of false assumptions about the state of identity confusion. -/- More positively, I assume an ‘explanation-driven’ approach, combining strands in Gricean intentionalism and Ruth Millikan’s teleosemantics. On this view, confused speakers are ‘sub-optimal’: their mental state disrupts the proper function of the relevant singular terms in their idiolects. Furthermore, I flesh out a theoretically fruitful notion of ‘edenic reference,’ which idealizes away from confusion in defining the optimal or stabilizing function of singular terms. I argue that speakers must satisfy certain broadly cognitive constraints if their utterances are to play a role in explaining the maintenance of a practice of using a singular term in a linguistic community.

Christine Korsgaard has attempted to defend a distinct approach to metaethics – Neo-Kantian Constructivism. Not only does she present a positive case for her own view, she also attacks existing metaethical positions and even the disctinctions that metaethics has traditionally relied on. This thesis is a sustained examination of this position. I consider whether Korsgaard can legitimately claim to be offering a metaethical position at all, providing her with some defence against the scepticism of some metaethicists. I also examine her (...) attacks on traditional metaethical positions. I argue that her attack on moral realism can be avoided if the realism on offer takes a particular form. In the case of expressivism I claim that Korsgaard’s attack, though not fully developed in her work, motivates an examination of contemporary hybrid-expressivist theories. I argue that these are, as of yet, no advance over their non-hybrid cousins. Finally I examine Korsgaard’s own position, attempting to make it clearer by combining her claims with a framework developed by Crispin Wright for judgement-dependent qualities. This gives Korsgaard her best chance of a distinctive metaethical position. Ultimately, though, the Neo-Kantian approach to morality fails. (shrink)

I propound a mechanistic theory of natural kinds in the human sciences. By examining a culture- bound psychiatric disorder, bulimia nervosa, I illustrate how partially socially constructed phenomena raise a serious challenge to traditional theories of natural kinds. As a solution to the challenge, I show how the mechanistic approach allows us to include real but partly socially sustained phenomena among natural kinds. This is desirable because the theory of natural kinds supplies the human sciences with a clear normative account (...) of concept formation. Furthermore, my theory suggests a conceptual framework for interdisciplinary research on complex phenomena. As a prerequisite for the mechanistic approach, the concept of natural kind in the philosophy of science must be distinguished from the use of the notion in other parts of philosophy. (shrink)

I argue, in this thesis, that proper name reference is a wholly pragmatic phenomenon. The reference of a proper name is neither constitutive of, nor determined by, the semantic content of that name, but is determined, on an occasion of use, by pragmatic factors. The majority of views in the literature on proper name reference claim that reference is in some way determined by the semantics of the name, either because their reference simply constitutes their semantics (which generally requires a (...) very fine-grained individuation of names), or because names have an indexical-like semantics that returns a referent given certain specific contextual parameters. I discuss and criticize these views in detail, arguing, essentially, in both cases, that there can be no determinate criteria for reference determination—a claim required by both types of semantic view. I also consider a less common view on proper name reference: that it is determined wholly by speakers’ intentions. I argue that the most plausible version of this view—a strong neo-Gricean position whereby all utterance content is determined by the communicative intentions of the speaker—is implausible in light of psychological data. In the positive part of my thesis, I develop a pragmatic view of proper name reference that is influenced primarily by the work of Charles Travis. I argue that the reference of proper names can only be satisfactorily accounted for by claiming that reference occurs not at the level of word meaning, but at the pragmatic level, on an occasion of utterance. I claim that the contextual mechanisms that determine the reference of a name on an occasion are the same kinds of thing that determine the truth-values of utterances according to Travis. Thus, names are, effectively, occasion sensitive in the way that Travis claims predicates and sentences (amongst other expressions) are. Finally, I discuss how further research might address how my pragmatic view of reference affects traditional issues in the literature on names, and the consequences of the view for the semantics of names.

Philosophical conceptual analysis is an experimental method. Focusing on this helps to justify it from the skepticism of experimental philosophers who follow Weinberg, Nichols & Stich. To explore the experimental aspect of philosophical conceptual analysis, I consider a simpler instance of the same activity: everyday linguistic interpretation. I argue that this, too, is experimental in nature. And in both conceptual analysis and linguistic interpretation, the intuitions considered problematic by experimental philosophers are necessary but epistemically irrelevant. They are like variables introduced (...) into mathematical proofs which drop out before the solution. Or better, they are like the hypotheses that drive science, which do not themselves need to be true. In other words, it does not matter whether or not intuitions are accurate as descriptions of the natural kinds that undergird philosophical concepts; the aims of conceptual analysis can still be met. (shrink)

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.
