This paper details the content and structure of the folk concept of life, and discusses its relevance for scientific research on life. In four empirical studies, we investigate which features of life are considered salient, universal, central, and necessary. Functionings, such as nutrition and reproduction, but not material composition, turn out to be salient features commonly associated with living beings (Study 1). By contrast, being made of cells is considered a universal feature of living species (Study 2), a central aspect (...) of life (Study 3), and our best candidate for being necessary for life (Study 4). These results are best explained by the hypothesis that people take life to be a natural kind subject to scientific scrutiny. (shrink)

This paper reports the first study in the literature that adopts a bibliometric approach to systematically explore the scholarship in the young and fast-growing research field of experimental philosophy. Based on a corpus of 1,248 publications in experimental philosophy from the past two decades retrieved from the PhilPapers website, the study examined the publication trend, the influential experimental philosophers, the impactful works, the popular publication venues, and the major research themes in this subarea of philosophy. It found, first, an overall (...) growing trend in publications in experimental philosophy, encompassing four developmental stages. Second, it found that significant changes in topics of interest have taken place, with some gaining increasing attention, others seemingly going out of fashion, and still others remaining popular constantly. Third, the study identified lists of leading philosophers, frequently cited publications, and popular journals helpful for researchers and newcomers to get a quick start in learning about the field.

In a recent paper, Joshua Knobe (2019) offers a startling account of the metaphilosophical implications of findings in experimental philosophy. We argue that Knobe’s account is seriously mistaken, and that it is based on a radically misleading portrait of recent work in experimental philosophy and cultural psychology.

Natural/social kind essentialism is the view that natural kind categories, both living and non-living natural kinds, as well as social kinds (e.g., race, gender), are essentialized. On this view, artifactual kinds are not essentialized. Our view—teleological essentialism—is that a broad range of categories are essentialized in terms of teleology, including artifacts. Utilizing the same kinds of experiments typically used to provide evidence of essentialist thinking—involving superficial change (study 1), transformation of insides (study 2) and inferences about offspring (study 3)—we find (...) support for the view that a broad range of categories—living natural kinds, non-living natural kinds and artifactual kinds—are essentialized in terms of teleology. Study 4 tests a unique prediction of teleological essentialism and also provides evidence that people make inferences about purposes which in turn guide categorization judgments. (shrink)

Placeholder essentialism is the view that there is a causal essence that holds category members together, though we may not know what the essence is. Sometimes the placeholder can be filled in by scientific essences, such as when we acquire scientific knowledge that the atomic weight of gold is 79. We challenge the view that placeholders are elaborated by scientific essences. On our view, if placeholders are elaborated, they are elaborated Aristotelian essences, a telos. Utilizing the same kinds of experiments (...) used by traditional essentialists—involving superficial change (study 1), transformation of insides (study 2), acquired traits (study 3) and inferences about offspring (study 4)—we find support for the view that essences are elaborated by a telos. And we find evidence (study 5) that teleological essences may generate category judgments. (shrink)

Most theories of concepts take concepts to be structured bodies of information used in categorization and inference. This paper argues for a version of atomism, on which concepts are unstructured symbols. However, traditional Fodorian atomism is falsified by polysemy and fails to provide an account of how concepts figure in cognition. This paper argues that concepts are generative pointers, that is, unstructured symbols that point to memory locations where cognitively useful bodies of information are stored and can be deployed to (...) resolve polysemy. The notion of generative pointers allows for unresolved ambiguity in thought and provides a basis for conceptual engineering. (shrink)

A puzzling feature of paradigmatic cases of dehumanization is that the perpetrators often attribute uniquely human traits to their victims. This has become known as the “paradox of dehumanization.” We address the paradox by arguing that the perpetrators think of their victims as human in one sense, while denying that they are human in another sense. We do so by providing evidence that people harbor a dual character concept of humanity. Research has found that dual character concepts have two independent (...) sets of criteria for their application, one of which is descriptive and one of which is normative. Across four experiments, we found evidence that people deploy a descriptive criterion according to which being human is a matter of being a Homo sapiens; as well as a normative criterion according to which being human is a matter of possessing a deep-seated commitment to do the morally right thing. Importantly, we found that people are willing to affirm that someone is human in the descriptive sense, while denying that they are human in the normative sense, and vice versa. In addition to providing a solution to the paradox of dehumanization, these findings suggest that perceptions of moral character have a central role to play in driving dehumanization. (shrink)

Psychological essentialism is the hypothesis that humans represent some categories as having an underlying essence that unifies members of a category and is causally responsible for their typical attributes and behaviors. Throughout the past several decades, psychological essentialism has emerged as an extremely active area of research in cognitive science. More recently, it has also attracted attention from philosophers, who put the empirical results to use in many different philosophical areas, ranging from philosophy of mind and cognitive science to social (...) philosophy. This article aims to give philosophers who are new to the topic an overview of the key empirical findings surrounding psychological essentialism, and some of the ways the hypothesis and its related findings have been discussed, extended, and applied in philosophical research.

The present research examines whether identity essentialism, an important component of psychological essentialism, is a fundamental feature of human cognition. Across three studies (Ntotal = 1723), we report evidence that essentialist intuitions about the identity of kinds are culturally dependent, demographically variable, and easily malleable. The first study considered essentialist intuitions in 10 different countries spread across four continents. Participants were presented with two scenarios meant to elicit essentialist intuitions. Their answers suggest that essentialist intuitions vary dramatically across cultures. Furthermore, (...) these intuitions were found to vary with gender, education, and across eliciting stimuli. The second study further examined whether essentialist intuitions are stable across different kinds of eliciting stimuli. Participants were presented with two different scenarios meant to elicit essentialist intuitions—the “discovery” and “transformation” scenarios. Their answers suggest that the nature of the eliciting stimuli influences whether or not people report essentialist intuitions. Finally, the third study demonstrates that essentialist intuitions are susceptible to framing effects. Keeping the eliciting stimulus (i.e., the scenario) constant, we show that the formulation of the question eliciting a judgment influences whether or not people have essentialist intuitions. Implications of these findings for identity essentialism and psychological essentialism, in general, are discussed. (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)

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual‐character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual‐character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of (...) cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual‐character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual‐character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual‐character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual‐character‐like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow‐up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored. (shrink)

We intuitively make a distinction between _lying_ and _misleading_. On the explanation of this phenomenon favored here—the _adverbial_ account—the distinction tracks whether the content and its truth-committing force are literally conveyed. On an alternative _commitment_ account, the difference between lying and misleading is predicated instead on the strength of assertoric commitment. One lies when one presents with full assertoric commitment what one believes to be false; one merely misleads when one presents it without full assertoric commitment, by merely hinting or (...) otherwise implying it. Now, as predicted by the well-supported assumption that we can also assert with pictures, the lying/misleading distinction appears to intuitively show up there too. Here I’ll explain how the debate confronting the two accounts plays out both in general and in that case, aiming to provide support for the adverbial account. (shrink)

The paper distinguishes between two conceptions of kinds defined by constitutive rules, the one suggested by Searle, and the one invoked by Williamson to define assertion. Against recent arguments to the contrary by Maitra, Johnson and others, it argues for the superiority of the latter in the first place as an account of games. On this basis, the paper argues that the alleged disanalogies between real games and language games suggested in the literature in fact don’t exist. The paper relies (...) on Rawls’s distinction between types of practices and institutions defined by constitutive rules, and those among them that are actually in force, and hence are truly normative; it defends along Rawlsian lines that a plurality of norms apply to actual instances of rule-constituted practices, and uses this Rawlsian line to block the examples that Maitra, Johnson and others provide to sustain their case.

ABSTRACT Most theorists agree that our social order includes a distinctive legal dimension. A fundamental question is that of whether reference to specific legal phenomena always involves a commitment to a particular moral view. Whereas many philosophers advance the ‘positivist’ claim that any correspondence between morality and the law is just a function of political circumstance, natural law theorists insist that law is intrinsically moral. Each school claims the crucial advantage of consistency with our folk concept. Drawing on the notion (...) of dual character concepts, we develop a set of hypotheses about the intuitive relation between a rule’s moral and legal aspects. We then report a set of studies that conflict unexpectedly with the predictions by legal positivists. Intuitively, an evil rule is not a fully-fledged instance of law. (shrink)

Over the past several decades, psychological essentialism has been an important topic of study, incorporating research from multiple areas of psychology, philosophy and linguistics. At its most basic level, essentialism is the tendency to represent certain concepts in terms of a deeper, unobservable property that is responsible for category membership. Originally, this concept was used to understand people’s reasoning about natural kind concepts, such as TIGER and WATER, but more recently, researchers have identified the emergence of essentialist-like intuitions in a (...) number of other contexts, including people’s representation of concepts like SCIENTIST or CHRISTIAN. This paper develops an account that aims to capture how essentialism may operate across these varied cases. In short, we argue that while there is diversity in the forms essentialism can take, these varied cases reflect the same underlying cognitive structure. (shrink)

Experiments have led some philosophers to conclude that the reference determination of natural kind terms is neither simply descriptive nor simply causal-historical. Various theories have been aired to account for this, including ambiguity, hybrid, and different-idiolects theories. Devitt and Porter (2021) hypothesized that some terms are covered by one theory, some another, with a place for all the proposed theories. The present paper tests hypotheses that the term ‘Rio de Janeiro Myrtle’ is simply causal-historical but the term ‘rice’ is hybrid. (...) For, whereas the former term is of scientific but little practical interest, the latter is not: rice is a significant part of the human diet. So, we predicted there would be two factors to the reference determination of ‘rice’: a superficial-descriptive one and a deep-causal one. Our experiments confirmed these hypotheses using the methods of elicited production and truth value judgments. We take our results to support the hybrid Theory of ‘rice’ rather than the ambiguity or different-idiolects theory. We were not testing ‘myrtle’ but, surprisingly, our results implied that ‘myrtle’ was partly descriptive and so like ‘rice’ but not ‘Rio de Janeiro Myrtle’. A follow-up experiment confirmed these puzzling results. More investigation is needed. (shrink)

Recent experimental work on “natural” kind terms has shown evidence of both descriptive and nondescriptive reference determination. This has led some to propose ambiguity or hybrid theories, as opposed to traditional description and causal‐historical theories of reference. Many of those experiments tested theories against referential intuitions. We reject this method, urging that reference should be tested against usage, preferably by elicited production. Our tests of the usage of a biological kind term confirm that there are indeed both descriptive and causal‐historical (...) elements to the reference determination of some natural kind terms. We argue that to accommodate our results and earlier ones, we should abandon the common assumption that any one theory of reference fits all natural kind terms. Rather, it is likely that some terms are descriptive, some causal‐historical, some ambiguous, and some hybrid. This substantive conclusion is accompanied by a methodological one. Our experiments, like some earlier ones, found participants contradicting both each other and themselves. We argue that these contradictions indicate a lack of linguistic competence with the term. We conclude that these experiments have been faulty, because they test terms that are novel to participants and/or use fantastical vignettes. We provide some suggestions for future research.

This book is about the idea that some true statements would have been true no matter how the world had turned out, while others could have been false. It develops and defends a version of the idea that we tell the difference between these two types of truths in part by reflecting on the meanings of words. It has often been thought that modal issues—issues about possibility and necessity—are related to issues about meaning. In this book, the author defends the (...) view that the analysis of meaning is not just a preliminary to answering modal questions in philosophy; it is not merely that before we can find out whether something is possible, we need to get clear on what we are talking about. Rather, clarity about meaning often brings with it answers to modal questions. In service of this view, the author analyzes the notion of necessity and develops ideas about linguistic meaning, applying them to several puzzles and problems in philosophy of language. Meaning and Metaphysical Necessity will be of interest to scholars and advanced students working in metaphysics, philosophy of language, and philosophical logic.
