Experiments on theories of reference have mostly tested referential intuitions. We think that experiments should rather be testing linguistic usage. Substantive Aim (I): to test classical description theories of proper names against usage by “elicited production.” Our results count decisively against those theories. Methodological Aim (I): Machery, Olivola, and de Blanc (2009) claim that truth-value judgment experiments test usage. Martí (2012) disagrees. We argue that Machery et al. are right and offer some results that are consistent with that conclusion. Substantive (...) Aim (II): Machery et al. provide evidence that the usage of a name varies, being sometimes descriptive, sometimes not. In seven out of eight tests of usage, we did not replicate this variation. Methodological Aim (II): to test the reliability of referential intuitions by comparing them with linguistic usage. Earlier studies led us to predict that we would find those intuitions unreliable, but we did not. Our results add to evidence that tests of referential intuition are susceptible to unpredictable wording effects. (shrink)

Machery et al. 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. In a recent article, Genoveva Martí argues that the type of intuitions examined by Machery and colleagues 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.To substantiate this criticism, Martí draws (...) a distinction between two types of intuitions: metalinguistic intuitions and what we will call ‘linguistic’ intuitions. Metalinguistic intuitions are judgements about the semantic properties of mentioned words, while, if we understand Martí correctly, linguistic intuitions are judgements about the individuals described in the actual and possible cases used by philosophers of language. These judgements would be expressed by sentences using words rather than mentioning them. An example might clarify this distinction. In Kripke's Gödel case, the judgement that the proper name ‘Gödel’ refers to Gödel and not to Schmidt is a metalinguistic intuition, since it is about the reference of the proper name ‘Gödel’; by contrast, the judgement that in this case Gödel should not have claimed credit for the incompleteness theorem is a linguistic intuition. Because Martí holds that only linguistic intuitions provide evidence for determining how reference is fixed and because Machery and colleagues used a question that elicited metalinguistic intuitions, she concludes that the variation in the relevant intuitions about reference ….

Some experimental studies have recently claimed to undermine semantic externalism about natural kind terms. However, it is unclear how philosophical accounts of reference can be experimentally tested. We present two externalistic adaptations of psychological placeholder essentialism, a strict externalist and a hybrid externalist view, which are experimentally testable. We examine Braisby, Franks, and Hampton's (1996) study which claims to undermine externalism, and argue that the study fails in its aims. We conducted two experiments, the results of which undermine internalism and (...) the hybrid theory, and support strict externalism. Our conclusion is that lay speakers' natural kind concepts involve a belief in an external category essence, which determines reference. (shrink)

One of the central debates in the philosophy of language is that between defenders of the causal-historical and descriptivist theories of reference. Most philosophers involved in the debate support one or the other of the theories. Building on recent experimental work in semantics, we argue that there is a sense in which both theories are correct. In particular, we defend the view that natural kind terms can sometimes take on a causal-historical reading and at other times take on a descriptivist (...) reading. The meaning will shift depending on the conversational setting. The theoretical view has roots in work by Kitcher. We present some original experiments that support the thesis. (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.

A standard methodology in philosophy of language is to use intuitions as evidence. Machery, Mallon, Nichols, and Stich challenged this methodology with respect to theories of reference by presenting empirical evidence that intuitions about one prominent example from the literature on the reference of proper names vary between Westerners and East Asians. In response, Sytsma and Livengood conducted experiments to show that the questions Machery and colleagues asked participants in their study were ambiguous, and that this ambiguity affected the responses (...) given by Westerners. Sytsma and Livengood took their results to cast doubt on the claim that the current evidence indicates that there is cross-cultural variation in intuitions about the Gödel case. In this paper we report on a new cross-cultural study showing that variation in intuitions remains even after controlling for the ambiguity noted by Sytsma and Livengood. (shrink)

The essentialist approach to word meaning has been used to undermine the fundamental assumptions of the cognitive psychology of concepts. Essentialism assumes that a word refers to a natural kind category in virtue of category members possessing essential properties. In support of this thesis, Kripke and Putnam deploy various intuitions concerning word use under circumstances in which discoveries about natural kinds are made. Although some studies employing counterfactual discoveries and related transformations appear to vindicate essentialism, we argue that the intuitions (...) have not been investigated exhaustively. In particular, we argue that discoveries concerning the essential properties of whole categories (rather than simply of particular category members) are critical to the essentialist intuitions. The studies reported here examine such discovery contexts, and demonstrate that words and concepts are not used in accordance with essentialism. The results are, however, consistent with "representational change" views of concepts, which are broadly Fregean in their motivation. We conclude that since essentialism is not vindicated by ordinary word use, it fails to undermine the cognitive psychology of concepts. (shrink)

Machery, Mallon, Nichols, and Stich [2004; forthcoming] use experimental methods to raise a spectre of doubt about reliance on intuitions in developing theories of reference which are then deployed in philosophical arguments outside the philosophy of language. Machery et al. ran a cross-cultural survey asking Western and East Asian participants about a famous case from the philosophical literature on reference (Kripke's G del example). They interpret their results as indicating that there is significant variation in participants' intuitions about semantic reference (...) for that case. We argue that this interpretation is mistaken. We detail a type of ambiguity found in Machery et al.'s probe but not yet noted in the response literature. We argue that this epistemic ambiguity could have affected their results. We do not stop there, however: Rather than rest content with a possibility claim, we ran four studies to test the impact of this ambiguity on participants' responses. We found that this accounts for much of the variation in Machery et al.'s original experiment. We conclude that in the light of our new data, their argument is no longer convincing. (shrink)

According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must appeal to (...) the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

UNCLEAR as it is, the traditional doctrine that the notion "meaning" possesses the extension/intension ambiguity has certain typical consequences. The doctrine that the meaning of a term is a concept carried the implication that mean- ings are mental entities. Frege, however, rebelled against this "psy- chologism." Feeling that meanings are public property-that the same meaning can be "grasped" by more than one person and by persons at different times-he identified concepts (and hence "intensions" or meanings) with abstract entities rather than (...) mental entities. However, "grasping" these abstract entities was still an individual psychological act. None of these philosophers doubted that understanding a word (knowing its intension) was just a matter of being in a certain psychological state (somewhat in the way in which knowing how to factor numbers in one's head is just a mat- ter of being in a certain very complex psychological state).

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.

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)

In their delightfully provocative paper, “Semantics, Cross-Cultural Style,” Edouard Machery, Ron Mallon, Shaun Nichols, and Stephen Stich (2004),[1] make several striking claims about theories of reference. First, they claim: (I) Philosophical views about reference “are assessed by consulting one’s intuitions about the reference of terms in hypothetical situations” (p. B1). This claim is prompted by their observations of the role of intuitions in Saul Kripke’s refutation of the descriptivist view of proper names in favor of a causal-historical view (1980). The (...) particular intuitions they attend to are those aired in discussing Kripke’s cases of Gödel and Jonah. This prompts the next claim: (II) Those particular cases are “central” to Kripke’s refutation (p. B1). Indeed, Machery et al describe these cases as “some of the most influential thought experiments in the philosophy of reference” (p. B8). Inspired by recent work in psychology (e.g., Nisbett et al 2001) that shows “systematic cognitive differences between East Asians and Westerners” (p. B1), Machery et al predicted that there would be cultural differences in referential intuitions. They conducted some ingenious experiments on Gödel and Jonah cases to test this predication. The results in the Gödel cases, although not in the Jonah cases, confirmed their prediction, leading them to conclude: “Westerners are more likely than East Asians to report intuitions that are consistent with the causal-historical view” (p. B1). And, implicitly, they claim: (III) These results raise serious doubts about Kripke’s refutation, which relies solely on the intuitions of Westerners. They are explicit about the following bolder claim: (IV) The fact of these cultural differences “raises questions about the nature of the philosophical enterprise of developing a theory of reference” (p. B1); it points to “significant philosophical conclusions” (p.. (shrink)

The article defends the doctrine that Linnaean taxa, including species, have essences that are, at least partly, underlying intrinsic, mostly genetic, properties. The consensus among philosophers of biology is that such essentialism is deeply wrong, indeed incompatible with Darwinism. I argue that biological generalizations about the morphology, physiology, and behavior of species require structural explanations that must advert to these essential properties. The objection that, according to current “species concepts,” species are relational is rejected. These concepts are primarily concerned with (...) what it is for a kind to be a species and throw little light on the essentialist issue of what it is for an organism to be a member of a particular kind. Finally, the article argues that this essentialism can accommodate features of Darwinism associated with variation and change. (shrink)

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Debates about natural kind concepts have sought to accommodate an apparent fact about ordinary people's judgments: Intuitively, the Twin Earth liquid is not water. We present results showing that people do not have this intuition. Instead, people tend to judge that there is (...) a sense in which the liquid is not water but also a sense in which it is water.

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.

E. Machery, R. Mallon, S. Nichols and S. Stich, have argued that there is empirical evidence against Kripke’s claim that names are not descriptive. Their argument is based on an experiment that compares the intuitions about proper name use of a group of English speakers in Hong Kong with those of a group of non-Chinese American students. The results of the experiment suggest that in some cultures speakers use names descriptively. I argue that such a conclusion is incorrect, for the (...) experiment does not prove what it is purported to prove. (shrink)

Martí argued that referential intuitions are not the right kind of empirical evidence for testing theories of reference. Machery, Olivola, and De Blanc replied with a survey aimed at providing evidence that referential intuitions are in sync with truth‐value judgments and argued that truth‐value judgments provide empirical data from linguistic usage. We present the results of a survey indicating that Machery, Olivola, and De Blanc's experiment fails to overcome Martí's objection: The truth‐value judgements tested by Machery, Olivola, and De Blanc (...) do not provide data relevant for testing theories of reference.

Machery argues: that “philosophers’ intuitions about reference are not more reliable than lay people’s —if anything, they are probably worse”; that “intuitions about the reference of proper names and uses of proper names provide equally good evidence for theories of reference”. lacks theoretical and empirical support. cannot be right because usage provides the evidence that intuitions are reliable.

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)

Following the influential thought experiments by Hilary Putnam and others, philosophers of language have for the most part adopted semantic externalism concerning natural kind terms. In this article, we present results from three experiments on the reference of natural kind terms. Our results confirm some standard externalist assumptions, but are in conflict with others: Ordinary speakers take both appearance and underlying nature to be central in their categorization judgments. Moreover, our results indicate that speakers’ categorization judgments are gradual, and proportional (...) to the degree of similarity between new samples and familiar, “standard” samples. These findings pose problems for traditional theories, both externalist and internalist. (shrink)
