Experimental Philosophy of Language

An open question in the semantics of modality is what relations there are among different modal flavours. In this article, we consider the thorny issue of whether ascribing to an agent the obligation to φ implies that it is possible for the agent to φ. Traditionally, this issue has been interpreted as whether ‘ought’ implies ‘can’. But another linguistic interpretation is available as well, namely, whether ‘must’ implies ‘can’ (MIC). We show that ‘must’ does imply ‘can’ via a convergent argument. (...) The first strand of the argument is theoretical: it consists in proving MIC from a well-established theory of modality in natural language, i.e., that proposed by Kratzer. The second strand is empirical: we present novel acceptability judgment studies showing that MIC predicts and explains the linguistic behaviour of native English speakers. (shrink)

This article presents an empirical examination of the consequences of the virtual entailment principle proposed by Jean Buridan to resolve the Liar paradox. This principle states that every sentence in natural language implicitly asserts its own truth. Adopting this principle means that the Liar sentence is not paradoxical but false, because its content is contradictory to what is virtually implied. As a result, humans should perceive the Liar sentence the same way as any other false sentence. This solution to the (...) Liar paradox received criticism for making ad hoc claims about the natural language. However, thanks to modern advancements in psychophysiology, it became possible to empirically investigate if the human brain really perceives the Liar sentence like a false sentence. We designed and conducted an experiment to examine brain activity in response to true sentences, false sentences and self-referential sentences. Our results provide support for the Buridan’s hypothesis and show that the Liar sentence is processed by the human brain identically to false sentences, while the Truthteller sentence is perceived identically to true sentences. This agrees with predictions derived from the virtual entailment principle and supports the idea that humans think with the logic of truth—a logic for which the truth is a designated value of its adequate semantics.

Sublinhando que a evocação dos acontecimentos que tiveram lugar ab origine convergir, segundo a perspectiva mítico-religiosa, para a manifestação das sagradas, de acordo com o referencial teórico-conceitual de Eliade, o artigo assinala que tal invocação implica uma correlação de narrativas míticas e gestos e ações paradigmáticas que se destinam a suscitar o poder sagrado e a produção de seus efeitos, ressaltando a prece como poder mágico de exercer influência sobrenatural, como afirma Mauss. Dessa forma, analisando a oração que ressalta o (...) monoteísmo judaico-cristão, o artigo assinala o relacionamento pactual que encerra Javé e Israel como um processo que implica a Sua invocação como Deus, que converge para manifestações e operações na vida do povo em sua realidade concreta , perfazendo, segundo a perspectiva bíblico-teológica neotestamentária, uma construção que encerra a expressão da existência escatológica e realização de si em Bultmann. Finalizando, baseado na perspectiva teológico-filosófica de Tillich, o texto rápido o poder que implica a oração em um processo que se sobrepõe às estruturas supraindividuais de destruição através do novo ser que Deus-Homem Jesus Cristo manifesta e que envolve uma capacidade de superar as estruturas escravizadoras do mal e as consequências autodestruidoras do estado de alienação existencial.

The recent controversy about misinformation has moved a question into the focus of the public eye that has occupied philosophers for decades: Under what conditions is it appropriate to assert a certain claim? When asserting a claim that x, must one know that x? Must x be true? Might it be normatively acceptable to assert whatever one believes? In the largest cross-cultural study to date (total n = 1,091) on the topic, findings from the United States, Germany, and Japan suggest (...) that, in order to claim that x, x need not be known, and it can be false. However, the data show, we do expect considerable epistemic responsibility on the speaker’s behalf: In order to appropriately assert a claim, the speaker must have good reasons to believe it.

In this paper, we present two experimental studies on reference of complex demonstratives. The results of our experiments challenge the dominant view in philosophy of language, according to which demonstrative reference is determined by the speaker's intentions. The first experiment shows that in a context where there are two candidates for the referent—one determined by the speaker’s intention, the other by some “external” factors—people prefer to identify the referent of a demonstrative with the latter object. The external factors for which (...) this prediction has been confirmed include the speaker’s demonstration and the descriptive content of a demonstrative. The second experiment shows that while this preference can be explained in terms of the speakers’ having different sorts of referential intentions, the relevant kind of intentions are fully opaque to the subjects. At the end of our paper, we point to some alternative accounts of demonstrative reference, including a pluralistic and hybrid approach, which can accommodate our experimental results. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions.

Thick terms and concepts, such as honesty and cruelty, are at the heart of a variety of debates in philosophy of language and metaethics. Central to these debates is the question of how the descriptive and evaluative components of thick concepts are related and whether they can be separated from each other. So far, no empirical data on how thick terms are used in ordinary language has been collected to inform these debates. In this paper, we present the first empirical (...) study, designed to investigate whether the evaluative component of thick concepts is communicated as part of the semantic meaning or by means of conversational implicatures. While neither the semantic nor the pragmatic view can fully account for the use of thick terms in ordinary language, our results do favour the semanticist interpretation: the evaluation of a thick concept is only slightly easier to cancel than semantically entailed content. We further discovered a polarity effect, demonstrating that how easily an evaluation can be cancelled depends on whether the thick term is of positive or negative polarity. (shrink)

Since Machery et al. Cognition 92, B1-B12 attacked Kripke’s refutation of classical descriptivism, their experiment has been repeated several times, in its original version or in some revised ones, by theorists with contrasting intents. Some repeated the experiment for confirming its results, others for proving them unreliable. One striking characteristic of those surveys is that they mostly replicated the data collected in Machery et al.’s Cognition 92, B1-B12, 2004 experiment: less than 60% of Westerners showed preference for the causal-historical response. (...) We side with the critics of Machery et al.’s experiment. In this paper, we present the results of a survey that tests some hypotheses for explaining that percentage of Westerners’ preferences without taking it as evidence that more than 40% of Westerners have descriptivist intuitions on semantic reference. The aim of our paper is not merely to question the reliability of Machery et al.’s experiment. In sections 4 and 5 we assess the impact of our survey on the current debate in experimental semantics. We provide a novel account of the nature of the epistemic ambiguity that affects experiments in theory of reference and explain the consequences that our account of the epistemic ambiguity has for subsequent works trying to avoid ambiguities.

This squib reports experimental findings from a study investigating the interpretation of simple disjunction in negative contexts in four languages: Italian, French, English, Romanian. We provide evidence that casts doubt on the robustness of the distinction between PPI disjunction languages and non-PPI disjunction languages. The difference turns out to be less clear-cut than assumed in the theoretical or experimental literature. The results reported here inform current accounts of positive polarity and flesh out some methodological issues raised by the various tasks (...) used in experimental investigations of the polarity sensitivity of disjunction.

Based on the new experimental evidence, we argue that a link between a conditional antecedent and the consequent is semantically expressed rather than pragmatically conveyed. In our paper, we focus on particular kinds of links which conditionals may convey in a context. For instance, a conditional ‘If p, q’ may convey a thought equivalent to ‘p will cause q’, ‘p is the best explanation for q’, ‘q follows from p’, etcetera. The traditional theoretical literature on conditionals seems to imply that (...) these specific links are generated pragmatically and are akin to conversational implicatures. In order to test this hypothesis, we used a well-recognized linguistic test from ‘reinforceability’, which serves to distinguish between a semantic and pragmatic level of meaning, and we designed an experimental study based on that test. The outcome of our study is that specific links conveyed by conditionals exhibit features of semantic entailments rather than conversational implicatures. This result accords with some of the recent findings in empirical investigations on conditionals. In the final part of our paper, we discuss various accounts of conditionals which can accommodate the results of our study. (shrink)

Like belief revision, conceptual change has rational aspects. The paper discusses this for predicate change. We determine the meaning of predicates by a set of imaginable instances, i.e., conceptually consistent entities that fall under the predicate. Predicate change is then an alteration of which possible entities are instances of a concept. The recent exclusion of Pluto from the category of planets is an example of such a predicate change. In order to discuss predicate change, we define a monadic predicate logic (...) with three different kinds of lawful belief: analytic laws, which hold for all possible instances; doxastic laws, which hold for the most plausible instances; and typicality laws, which hold for typical instances. We introduce predicate changing operations that alter the analytic laws of the language and show that the expressive power is not affected by the predicate change. One can translate the new laws into old laws and vice versa. Moreover, we discuss rational restrictions of predicate change. These limit its possible influence on doxastic and typicality laws. Based on the results, we argue that predicate change can be quite conservative and sometimes even hardly recognisable. (shrink)

Colleagues are not only an integral part of many people’s lives; empirical research suggests that having a good relationship with one’s colleagues is the single most important factor for being happy at work. However, so far, no one has provided a comprehensive account of what it means to be a colleague. To address this lacuna, we have conducted both an empirical as well as theoretical investigation into the content and structure of the concept ‘colleague.’ Based on the empirical evidence that (...) we present in this paper, we argue that ‘colleague’ is a dual character concept that has both a descriptive and a normative basis for categorization. Its descriptive dimension is characterized by three features, according to which two people are colleagues if they work for the same institution and know each other, or if they work for the same institution and work in the same field. An independent normative dimension is revealed, which shows that, as colleagues, we are expected to fulfill substantial normative expectations. Understanding the expectations that are encoded in the very structure of this concept is crucial to lay the groundwork for an ethics of collegiality. (shrink)

This paper empirically raises and examines the question of ‘conceptual control’: To what extent are competent thinkers able to reason properly with new senses of words? This question is crucial for conceptual engineering. This prominently discussed philosophical project seeks to improve our representational devices to help us reason better. It frequently involves giving new senses to familiar words, through normative explanations. Such efforts enhance, rather than reduce, our ability to reason properly, only if competent language users are able to abide (...) by the relevant explanations, in language comprehension and verbal reasoning. This paper examines to what extent we have such ‘conceptual control’ in reasoning with new senses. The paper draws on psycholinguistic findings about polysemy processing to render this question empirically tractable and builds on recent findings from experimental philosophy to address it. The paper identifies a philosophically important gap in thinkers’ control over the key process of stereotypical enrichment and discusses how conceptual engineers can use empirical methods to work around this gap in conceptual control. The paper thus empirically demonstrates the urgency of the question of conceptual control and explains how experimental philosophy can empirically address the question, to render conceptual engineering feasible as an ameliorative enterprise.

This paper trials new experimental methods for the analysis of natural language reasoning and the development of critical ordinary language philosophy in the wake of J.L. Austin. Philosophical arguments and thought experiments are strongly shaped by default pragmatic inferences, including stereotypical inferences. Austin suggested that contextually inappropriate stereotypical inferences are at the root of some philosophical paradoxes and problems, and that these can be resolved by exposing those verbal fallacies. This paper builds on recent efforts to empirically document inappropriate stereotypical (...) inferences that may drive philosophical arguments. We demonstrate that previously employed questionnaire-based output measures do not suffice to exclude relevant confounds. We then report an experiment that combines reading time measurements with plausibility ratings. The study seeks to provide evidence of inappropriate stereotypical inferences from appearance verbs that have been suggested to lie at the root of the influential ‘argument from illusion’. Our findings support a diagnostic reconstruction of this argument. They provide the missing component for proof of concept for an experimental implementation of critical ordinary language philosophy that is in line with the ambitions of current ‘evidential’ experimental philosophy.

Confused terms appear to signify more than one entity. Carnap maintained that any putative name that is associated with more than one object in a relevant universe of discourse fails to be a genuine name. Although many philosophers have agreed with Carnap, they have not always agreed among themselves about the truth-values of atomic sentences containing such terms. Some hold that such atomic sentences are always false, and others claim they are always truth-valueless. Field maintained that confused terms can still (...) refer, albeit partially, and offered a supervaluational account of their semantic properties on which some atomic sentences with confused terms can be true. After outlining many of the most important theoretical considerations for and against various semantic theories for such terms, we report the results of a study designed to investigate which of these accounts best accords with the truth-value judgments of ordinary language users about sentences containing these terms. We found that naïve participants view confused names as capable of successfully referring to one or more objects. Thus, semantic theories that judge them to involve total reference failure do not comport well with patterns of ordinary usage. (shrink)

This paper presents experimental data relevant to understanding the modal free choice effect (Kamp, 1973) when there are more than two disjuncts under the relevant modal operator. The results suggest that speakers' willingness to draw free choice inferences is correlated with whether the embedded disjuncts are *modally separable*, in a sense brought into focus by considering cases within which the relevant propositions fail to be pairwise redundant but are redundant as a set.

This paper revisits a study by Machery et al., suggesting that, in experimental versions of Kripke’s fictional cases on the use of proper names, Westerners are more likely than East Asian participants to show intuitions compatible with Kripke’s causal-historical theory of reference. We conducted two experiments, recruting participants from Norway and Bangladesh, either in English or in the participants’ native languages, using modified cases and a new approach to data analysis. We replicated the results of Machery et al., but we (...) show that the residual finding—i.e., that participants who are not aligned with CH produce responses consistent with a definite descriptions theory of reference—does not hold. Most participants in our experiments, and nearly all those who do not provide CH answers, respond as predicted by a theory that accommodates speaker’s reference in reasoning about uses of proper names, not according to DD. We suggest that cross-cultural variation in this task is real. However, explanations of variation within or across cultures need not invoke competing theories of reference, and can be unified within a single, broadly Kripkean analysis that honors the basic distinction between semantic reference and speaker’s reference.

We present two experimental studies on the Italian expressive ‘stronzo’. The first study tests whether, and to which extent, the acceptability of using an expressive is sensitive to the information available in the context. The study looks both at referential uses of expressives and predicative uses of expressives. The results show that expressives are sensitive to contextual information to a much higher degree than the non-expressive control items in their referential use, but also, albeit to a lesser degree, in their (...) predicative use. The second study tests whether the lower acceptability of expressives in their predicative use may be simply due to saying something negative about someone. A comparison between expressives, such as ‘jerk’, and non-expressive negative terms, such as ‘nasty’ or ‘unbearable’, suggests that it is the expressive nature of these terms, rather than the mere negative valence, that affects acceptability. Our studies present a major challenge to the existing accounts of expressives, and raise several theoretical issues that still call for an answer. (shrink)

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence φ allows for cases in which one party utters φ and the other its negation, and neither party’s claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a (...) doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other’s claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the par- ties to reject each other’s claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. e existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well. (shrink)

The generic overgeneralization effect is an attested tendency to accept false universal generalizations such as “all eagles fly” or “all snakes lay eggs” as true. In this paper, we discuss the generic overgeneralization effect demonstrated by Polish adult speakers. We asked 313 native speakers of Polish to evaluate universal quantified generalizations such as “all eagles fly” or “all snakes lay eggs” as true or false. The control group of 107 respondents provided data on the acceptance rates of the corresponding generic (...) generalizations such as “eagles fly” or “snakes lay eggs”. By determining the impact of test fillers on the participants’ acceptance rates, the study aimed to identify the scope of the generic overgeneralization effect. We manipulated four conditions: the universal negative, positive, neutral, and generic control conditions. The results showed significant differences between the first two conditions, but neither the negative nor the positive condition differed from the neutral one. The overall acceptance rates of universal statements were 63% for the negative condition, 49% for the positive condition, 55% for the neutral condition, and 90% for the control group. Overall, the participants accepted universal quantified statements at high rates even when they were prompted to reject them. The results may be interpreted as another piece of evidence in support of the generic overgeneralization effect. (shrink)

This paper presents an experimental study on definite descriptions. According to the classical views, a definite description, i.e., a phrase of the form “the F”, has – roughly speaking - purely descriptive semantics, that is, it designates the object which uniquely satisfies the description. However, as several philosophers including Keith Donnellan have argued, there are uses of definite descriptions on which these expressions do not seem to designate objects which satisfy the descriptions. Namely, a description may refer in some circumstances (...) to an object which does not have the property from the description. This argument is called “the Argument from misdescription” and it is raised against the classical views on the semantics of definite descriptions. In our paper, we present an experimental study on misdescription and explored reactions of ordinary users of language to various statements involving misdescriptions. The results of our research indicate that the intuition of ordinary speakers is consistent with the prediction expressed in the Argument from misdescription. We argue that the most common pragmatic explanation of misdescription, appealing to Gricean distinction between saying and meaning, is unconvincing. We vote for an alternative semantic account of definite descriptions, on which a description “the F” designates an object being F, which is at the same time the most salient individual according to a contextually established ranking of salience.

In this paper, I survey and defend the use of quantitative methods in philosophy of language. Quantitative methods in philosophy of language include a wide variety of methods, ranging from model‐based techniques (computer simulations and mathematical models) to data‐driven approaches (experimental philosophy and corpus‐based studies). After offering a few case studies of these methodologies in action, I single out some debates in philosophy of language that are especially well served by their use. These are cases in which quantitative methods increase (...) precision, improve the accuracy and reliability of results, and allow philosophers of language to borrow from other fields the best epistemic practices available. I conclude with some far‐reaching considerations about the role of qualitative and quantitative methods in debates about philosophical methodology. (shrink)

Simple claims with the verb ‘seem’, as well as the specific sensory verbs, ‘look’, ‘sound’, etc., require the speaker to have some relevant kind of perceptual acquaintance (Pearson, 2013; Ninan, 2014). But different forms of these reports differ in their perceptual requirements. For example, the copy raising (CR) report, ‘Tom seems like he’s cooking’ requires the speaker to have seen Tom, while its expletive subject (ES) variant, ‘It seems like Tom is cooking’, does not (Rogers, 1972; Asudeh and Toivonen, 2012). (...) This contrast has led some theorists to hold that the matrix subject in CR constructions is uniformly interpreted as the perceptual source (p-source) (Asudeh and Toivonen, 2012; Rett and Hyams, 2014). Others, based on examples of CR reports that seem not to require perception of the referent of the matrix subject, have taken the p-source interpretation instead to be non-uniform across CR reports (Landau, 2011; Doran, 2015). We reconsider these theoretical approaches to copy raising in light of new experimental work probing the sensitivity of these requirements to the matrix verb, the embedded ‘like’-clause, and the context. While we find some motivation for a non-uniform p-source analysis, it comes from importantly different cases than those others have relied on. Furthermore, our findings cast doubt on the prevalent assumption that the perceptual requirements of CR reports are to be captured solely by the presence or absence of the p-source interpretation. We suggest that the data motivating a non-uniform p-source view are better captured by an alternative approach, which makes use of a more minimal evidential source role, in place of the perceptual source role. We close by considering the relationship between English copy raising and evidential constructions cross-linguistically. (shrink)

Some assertions give rise to the acquaintance inference: the inference that the speaker is acquainted with some individual. Discussion of the acquaintance inference has previously focused on assertions about aesthetic matters and personal tastes (e.g. 'The cake is tasty'), but it also arises with reports about how things seem (e.g. 'Tom seems like he's cooking'). 'Seem'-reports give rise to puzzling acquaintance behavior, with no analogue in the previously-discussed domains. In particular, these reports call for a distinction between the specific acquaintance (...) inference (that the speaker is acquainted with a specific individual) and the general acquaintance inference (that the speaker is acquainted with something or other of relevance). We frame a novel empirical generalization -- the specific with stage-level generalization -- that systematizes the observed behavior, in terms of the semantics of the embedded 'like'-clause. We present supporting experimental work, and explain why the generalization makes sense given the evidential role of 'seem'-reports. Finally, we discuss the relevance of this result for extant proposals about the semantics of 'seem'-reports. More modestly, it fills a gap in previous theories by identifying which reports get which of two possible interpretations; more radically, it suggests a revision of the kind of explanation that should be given for the acquaintance behavior in question.

This paper is a contribution to the debate concerning the kind of philosophical conclusions that can (or cannot) be derived from systematic empirical studies of intuitions about the reference of proper names. The focus of the paper is the famous study by Machery et al. (2004) in which intercultural differences in semantic intuitions between American and Chinese participants were observed. Machery et al. used the obtained results to question the usefulness of intuitions in philosophical discussions concerning the reference of proper (...) names. In this paper, I present the results of my own philosophical-experimental studies aimed at analyzing methods used in research dedicated to the problem of reference rather than semantic intuitions as such. These results indicate a significant instability of responses regarding the reference of proper names and their susceptibility to the impact of philosophically insignificant factors. Based on the collected data, I argue that methods used in experimental studies concerning the reference of proper names conducted to date do not guarantee the assessment of intuitions of the desired kind.

According to contextualism, vast majority of natural-language expressions are context-sensitive. When testing whether this claim is reflected in Folk intuitions, some interesting methodological questions were raised such as: which experimental design is more appropriate for testing contextualism – the within- or the between-subject design? The main thesis of this paper is that the between-subject design should be preferred. The first experiment aims at assessing the difference between the results obtained for within-subjects measurements (where all participants assess all contexts) and between-subject (...) measurements (where respondents evaluating different contexts are distinct groups). It is shown that the within-subject design provides data that seems to support contextualism. However, I present an alternative, invariantist interpretation of these results, therefore showing that the within-subject design does not allow to empirically distinguish between contextualism and invariantism. The second experiment further elaborates the issue of how perceiving the contrast between contexts can affect subjects’ judgments – I show that certain kinds of contexts may elicit opposite intuitions when contrasted with different contexts.

Disjunctive antecedent conditionals —conditionals of the form if A or B, C—sometimes seem to entail both of their simplifications and sometimes seem not to. I argue that this behavior reveals a genuine ambiguity in DACs. Along the way, I discuss a new observation about the role of focal stress in distinguishing the two interpretations of DACs. I propose a new theory, according to which the surface form of a DAC underdetermines its logical form: on one possible logical form, if A (...) or B, C does entail both of its simplifications, while on the other, it does not.

ABSTRACTRecent debate over the semantics and pragmatics of epistemic modals has focused on intuitions about cross-contextual truth-value assessments. In this paper, we advocate a different approach to evaluating theories of epistemic modals. Our strategy focuses on judgments of the incompatibility of two different epistemic possibility claims, or two different truth value assessments of a single epistemic possibility claim. We subject the predictions of existing theories to empirical scrutiny, and argue that existing contextualist and relativist theories are unable to account for (...) the full pattern of observed judgments. As a way of illustrating the theoretical upshot of these results, we conclude by developing a novel theory of epistemic modals that is able to predict the results. (shrink)

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain theories (...) in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

Decades of research have investigated the complex role of source credibility in attitude persuasion. Current theories of persuasion predict that when messages are thoughtfully scrutinized, argument strength will tend to have a greater effect on attitudes than source credibility. Source credibility can affect highly elaborated attitudes, however, when individuals evaluate material that elicits low attitude extremity. A recently proposed model called the guru effect predicts that source credibility can also cause attitudinal change by biasing the interpretation of pragmatically ambiguous material. (...) The present studies integrate models of explanatory pragmatics and persuasion in order to empirically assess these hypotheses. Experiment 1 found that text difficulty and attitude neutrality reflect independent persuasion variables. Experiment 2 found that higher source credibility causes more favorable attitudes toward messages eliciting low attitude extremity. Text difficulty was not found to have a significant effect on attitudes. These results confirm the predictions of prior social cognition research but no do not support the guru effect model. The implications of these studies for pragmatics and persuasion research as well as the value of interdisciplinary research between these fields are discussed. (shrink)

In 2004 Edouard Machery, Ron Mallon, Shaun Nichols and Stephen Stich published what has become one of the most widely discussed papers in experimental philosophy, in which they reported that East Asian and Western participants had different intuitions about the semantic reference of proper names. A flurry of criticisms of their work has emerged, and although various replications have been performed, many critics remain unconvinced. We review the current debate over Machery et al.’s (2004) results and take note of which (...) objections to their work have been satisfactorily answered and which ones still need to be addressed. We then report the results of studies that reveal significant cross-cultural and intra-cultural differences in semantic intuitions when we control for variables that critics allege have had a potentially distorting effect on Machery et al.’s findings. These variables include the epistemic perspective from which participants are supposed to understand the research materials, unintended anchoring effects of those materials, and pragmatic factors involved in the interpretation of speech acts within them. Our results confirm the robustness of the cross-cultural differences observed by Machery et al. and thereby strengthen the philosophical challenge they pose. (shrink)

Many of Tarski’s better known papers are either about or include lengthy discussions of how to properly define various concepts: truth, logical consequence, semantic concepts, or definability. In general, these papers identify two primary conditions for successful definitions: formal correctness and material adequacy. Material adequacy requires that the concept expressed by the formal definition capture the intuitive content of truth. Our primary interest in this paper is to better understand Tarski’s thinking about material adequacy, and whether components of his view (...) developed over time. More precisely, we are concerned with how Tarski’s understanding of the content of the common-sense, every-day usage of truth may have developed over time. We distinguish this concern from the character of the extensional criterion of adequacy Tarski proposes: that a materially adequate definition must entail all instances of Convention T. We will develop our reading of Tarski as follows: first, we will review the “Polemical Remarks,” focusing primarily on §§14 and 17, and Tarski’s references to Naess’ empirical research. Next, we will provide a summary and discussion of Naess’ work, especially his findings with respect to Tarski’s definition of truth and his research that suggests there is no single common or everyday concept of truth. Third, we will consider several possible objections to our interpretation of the Tarski–Naess dialectic. We will conclude that Tarski’s conception of material adequacy developed over time, potentially because of what he had learned through his interactions with Naess. (shrink)

The first balanced and detailed study of the central methodological issues in the philosophy of language.

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)

In this paper, we compare the formal semantics approach to genericity, within which genericity is viewed as a species of quantification, and a growing body of experimental and developmental work on the topic, mainly by psychologists rather than linguists, proposing that genericity is categorically different from quantification. We argue that this generics-as-default hypothesis is much less well supported by evidence than its supporters contend, and that a research program combining theoretical and experimental research methods and considerations in the same studies (...) is required to make progress.

The standard view in social science and philosophy is that lying does not require the liar’s assertion to be false, only that the liar believes it to be false. We conducted three experiments to test whether lying requires falsity. Overall, the results suggest that it does. We discuss some implications for social scientists working on social judgments, research on lie detection, and public moral discourse.

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.

Past work has shown systematic differences between Easterners' and Westerners' intuitions about the reference of proper names. Understanding when these differences emerge in development will help us understand their origins. In the present study, we investigate the referential intuitions of English- and Chinese-speaking children and adults in the U.S. and China. Using a truth-value judgment task modeled on Kripke's classic Gödel case, we find that the cross-cultural differences are already in place at age seven. Thus, these differences cannot be attributed (...) to later education or enculturation. Instead, they must stem from differences that are present in early childhood. We consider alternate theories of reference that are compatible with these findings and discuss the possibility that the cross-cultural differences reflect differences in perspective-taking strategies.

In this paper, we present and discuss the findings of two experiments about reference change. Cases of reference change have sometimes been invoked to challenge traditional versions of semantic externalism, but the relevant cases have never been tested empirically. The experiments we have conducted use variants of the famous Twin Earth scenario to test folk intuitions about whether natural kind terms such as ‘water’ or ‘salt’ switch reference after being constantly (mis)applied to different kinds. Our results indicate that this is (...) indeed so. We argue that this finding is evidence against Saul Kripke’s causal-historical view of reference, and at least provisional evidence in favor of the causal source view of reference as suggested by Gareth Evans and Michael Devitt.

This paper is a contribution to the debate concerning the kind of philosophical conclusions that can be derived from systematic empirical studies of intuitions about the reference of proper names. The focus of the paper is the famous study by Machery et al. in which intercultural differences in semantic intuitions between American and Chinese participants were observed. Machery et al. used the obtained results to question the usefulness of intuitions in philosophical discussions concerning the reference of proper names. In this (...) paper, I present the results of my own philosophical-experimental studies aimed at analyzing methods used in research dedicated to the problem of reference rather than semantic intuitions as such. These results indicate a significant instability of responses regarding the reference of proper names and their susceptibility to the impact of philosophically insignificant factors. Based on the collected data, I argue that methods used in experimental studies concerning the reference of proper names conducted to date do not guarantee the assessment of intuitions of the desired kind.

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.

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). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to accommodate (...) an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

Grau and Pury (Review of Philosophy and Psychology, 5, 155–168, 2014) reported that people’s views about love are related to their views about reference. This surprising effect was however not replicated in Cova et al.’s (in press) replication study. In this article, we show that the replication failure is probably due to the replication’s low power and that a metaanalytic reanalysis of the result in Cova et al. suggests that the effect reported in Grau and Pury is real. We then (...) report a large, highly powered replication that successfully replicates Grau and Pury 2014. This successful replication is a case study in the challenges involved in replicating scientific work, and our article contributes to the discussion of these challenges. (shrink)
