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.

Claims about people's intuitions have long played an important role in philosophical debates. The new field of experimental philosophy seeks to subject such claims to rigorous tests using the traditional methods of cognitive science – systematic experimentation and statistical analysis. Work in experimental philosophy thus far has investigated people's intuitions in philosophy of language, philosophy of mind, epistemology, and ethics. Although it is now generally agreed that experimental philosophers have made surprising discoveries about people's intuitions in each of these areas, considerable disagreement remains about the philosophical significance of the key findings. Some have argued that work in experimental philosophy should be assessed by asking whether it can contribute to the kind of inquiry that is normally pursued within analytic philosophy, while others suggest that work in experimental philosophy is best understood as a contribution to a more traditional sort of philosophical inquiry that long predates the birth of analytic philosophy.

The objectivity and utility of experimental data as evidential support for knowledge-claims may be found suspect when it is shown that (a) the interpretation of experimental data is inevitably complicated by social factors like experimenter effects, subject effects and demand characteristics, (b) social factors which affect experimental data are themselves sensitive to societal conventions or cultural values, (c) all observations (including experimental observations) are necessarily theory-dependent, and (d) experimental data have limited generality because they are collected in artificial settings. These critiques of experimental data are answered by showing that (i) not all empirical studies are experiments, (ii) experimental methodology is developed to exclude alternate interpretations of data (including explanations in terms of social influences), (iii) theoretical disputes and their settlement take place in the context of a particular frame of reference, and (iv) objectivity can be achieved with observations neutral to the to-be-corroborated theory despite theory-dependent observations if distinctions are made (a) between prior observation and evidential observation and (b) between a to-be-corroborated theory and the theory underlying the identity of evidential response.

Proponents of linguistic philosophy hold that all non-empirical philosophical problems can be solved by either analyzing ordinary language or developing an ideal one. I review the debates on linguistic philosophy and between ordinary and ideal language philosophy. Using arguments from these debates, I argue that the results of experimental philosophy on intuitions support linguistic philosophy. Within linguistic philosophy, these experimental results support and complement ideal language philosophy. I argue further that some of the critiques of experimental philosophy are in fact defenses of ideal language philosophy. Finally, I show how much of the current debate about experimental philosophy is anticipated in the debates about and within linguistic philosophy. Specifically, arguments by ideal language philosophers support experimental philosophy.

In two fascinating articles, Machery, Mallon, Nichols, and Stich use experimental methods to raise a specter 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 subjects about a famous case from the philosophical literature on reference (Kripke’s Gödel example). They found significant variation in subjects’ intuitions about that case. While there have been a number of theoretical responses to this work, there have not yet been any experimental responses. This paper fills that gap. We noticed an ambiguity in the question Machery et al. posed in their original experiment; we then ran four studies to test the impact of this ambiguity on subjects’ responses. We found that the ambiguity accounts for much of the variation found in their original experiment. We argue that in the light of our data, Machery et al.’s argument is no longer convincing.

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..

It is common in various quarters of philosophy to derive philosophically significant conclusions from theories of reference. In this paper, we argue that philosophers should give up on such ‘arguments from reference.’ Intuitions play a central role in establishing theories of reference, and recent cross-cultural work suggests that intuitions about reference vary across cultures and between individuals within a culture (Machery et al. 2004). We argue that accommodating this variation within a theory of reference undermines arguments from reference.

While philosophers of language have traditionally relied upon their intuitions about cases when developing theories of reference, this methodology has recently been attacked on the grounds that intuitions about reference, far from being universal, show significant cultural variation, thus undermining their relevance for semantic theory. I’ll attempt to demonstrate that (1) such criticisms do not, in fact, undermine the traditional philosophical methodology, and (2) our underlying intuitions about the nature of reference may be more universal than the authors suppose.

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.

Practitioners of the new ‘experimental philosophy’ have collected data that appear to show that some philosophical intuitions are culturally variable. Many experimental philosophers take this to pose a problem for a more traditional, ‘armchair’ style of philosophizing. It is argued that this is a mistake that derives from a false assumption about the character of philosophical methods; neither philosophy nor its methods have anything to fear from cultural variability in philosophical intuitions.
