Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

In epistemology, fake-barn thought experiments are often taken to be intuitively clear cases in which a justified true belief does not qualify as knowledge. We report a study designed to determine whether non-philosophers share this intuition. The data suggest that while participants are less inclined to attribute knowledge in fake-barn cases than in unproblematic cases of knowledge, they nonetheless do attribute knowledge to protagonists in fake-barn cases. Moreover, the intuition that fake-barn cases do count as knowledge is negatively correlated with (...) age; older participants are less likely than younger participants to attribute knowledge in fake-barn cases. We also found that increasing the number of defeaters (fakes) does not decrease the inclination to attribute knowledge. (shrink)

There have recently been a number of strong claims that normative considerations, broadly construed, influence many philosophically important folk concepts and perhaps are even a constitutive component of various cognitive processes. Many such claims have been made about the influence of such factors on our folk notion of causation. In this paper, we argue that the strong claims found in the recent literature on causal cognition are overstated, as they are based on one narrow type of data about a particular (...) type of causal cognition; the extant data do not warrant any wide-ranging conclusions about the pervasiveness of normative considerations in causal cognition. Of course, almost all empirical investigations involve some manner of ampliative inference, and so we provide novel empirical results demonstrating that there are types of causal cognition that do not seem to be influenced by moral considerations.

In Philosophy Within Its Proper Bounds, Edouard Machery argues that resolving many traditional and contemporary philosophical issues is beyond our epistemic reach and that philosophy should re-orient itself toward more humble, but ultimately more important intellectual endeavors, such as the analysis of concepts.

<P>Experimental philosophy is one of the most active and exciting areas in philosophy today. In <EM>Current Controversies in Experimental Philosophy</EM>, Elizabeth O’Neill and Edouard Machery have brought together twelve leading philosophers to debate four topics central to recent research in experimental philosophy.

La philosophie expérimentale est un mouvement récent qui tente de faire progresser certains débats philosophiques grâce à l'utilisation de méthodes expérimentales. À la différence de la philosophie conventionnelle qui privilégie l'analyse conceptuelle ou la spéculation, la philosophie expérimentale préconise le recours aux études empiriques pour mieux comprendre les concepts philosophiques. Apparue il y a une dizaine d'années dans les pays anglo-saxons, cette approche constitue actuellement l'une des branches les plus dynamiques de la philosophie contemporaine. -/- L'objectif de cet ouvrage est (...) d'offrir un contact direct avec les travaux les plus connus et les plus discutés des philosophes expérimentaux. Il regroupe ainsi dix textes représentatifs de ce domaine jeune, mais déjà florissant, et couvre une large partie du champ philosophique contemporain (philosophie du langage, théorie de la connaissance, conscience, théorie de l'action, éthique et philosophie des sciences).

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.

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to (...) engage in “reflective” thinking. (shrink)

Dans cet entretien, Henry Bernstein revient sur la fondation des études agraires critiques et les principaux concepts qu’il a développés pour une étude marxiste de la sociologie rurale. Il montre comment l’opposition entre léninisme et populisme se rejoue dans l’épistémologie de la structure de classe de la paysannerie.

Reverse inference is the most commonly used inferential strategy for bringing images of brain activation to bear on psychological hypotheses, but its inductive validity has recently been questioned.

Both an ideal entrée for beginning readers and a solid text for scholars, the second edition of Peter Kalkavage's acclaimed translation of Plato's _Timaeus_ brings enhanced accessibility to a rendering well known for its faithfulness to the original text. An extensive essay offers insights into the reading of the work, the nature of Platonic dialogue, and the cultural background of the _Timaeus_. Appendices on music, astronomy, and geometry provide additional guidance. A brief outline of the themes of the work, (...) a detailed glossary, and a selected bibliography are also included.

In this article, we present evidence that in four different cultural groups that speak quite different languages there are cases of justified true beliefs that are not judged to be cases of knowledge. We hypothesize that this intuitive judgment, which we call “the Gettier intuition,” may be a reflection of an underlying innate and universal core folk epistemology, and we highlight the philosophical significance of its universality.

Recent experimental fi ndings by Knobe and others ( Knobe, 2003; Nadelhoffer, 2006b; Nichols and Ulatowski, 2007 ) have been at the center of a controversy about the nature of the folk concept of intentional action. I argue that the signifi cance of these fi ndings has been overstated. My discussion is two-pronged. First, I contend that barring a consensual theory of conceptual competence, the signifi cance of these experimental fi ndings for the nature of the concept of intentional action (...) cannot be determined. Unfortunately, the lack of progress in the philosophy of concepts casts doubt on whether such a consensual theory will be found. Second, I propose a new, defl ationary interpretation of these experimental fi ndings, ‘ the trade-off hypothesis ’ , and I present several new experimental fi ndings that support this interpretation.

Over recent years, the psychology of concepts has been rejuvenated by new work on prototypes, inventive ideas on causal cognition, the development of neo-empiricist theories of concepts, and the inputs of the budding neuropsychology of concepts. But our empirical knowledge about concepts has yet to be organized in a coherent framework. -/- In Doing without Concepts, Edouard Machery argues that the dominant psychological theories of concepts fail to provide such a framework and that drastic conceptual changes are required to (...) make sense of the research on concepts in psychology and neuropsychology. Machery shows that the class of concepts divides into several distinct kinds that have little in common with one another and that for this very reason, it is a mistake to attempt to encompass all known phenomena within a single theory of concepts. In brief, concepts are not a natural kind. Machery concludes that the theoretical notion of concept should be eliminated from the theoretical apparatus of contemporary psychology and should be replaced with theoretical notions that are more appropriate for fulfilling psychologists' goals. The notion of concept has encouraged psychologists to believe that a single theory of concepts could be developed, leading to useless theoretical controversies between the dominant paradigms of concepts. Keeping this notion would slow down, and maybe prevent, the development of a more adequate classification and would overshadow the theoretical and empirical issues that are raised by this more adequate classification. Anyone interested in cognitive science's emerging view of the mind will find Machery's provocative ideas of interest. (shrink)

In several disciplines within science—evolutionary biology, molecular biology, astrobiology, synthetic biology, artificial life—and outside science—primarily ethics—efforts to define life have recently multiplied. However, no consensus has emerged. In this article, I argue that this is no accident. I propose a dilemma showing that the project of defining life is either impossible or pointless. The notion of life at stake in this project is either the folk concept of life or a scientific concept. In the former case, empirical evidence shows that (...) life cannot be defined. In the latter case, I argue that, although defining life may be possible, it is pointless. I conclude that scientists, philosophers, and ethicists should discard the project of defining life.

Plato's Phaedo, written by legendary author Plato, is widely considered to be one of the greatest classic texts of all time. This great classic will surely attract a whole new generation of readers. For many, Plato's Phaedo is required reading for various courses and curriculums.

Published by Classic Books International and beautifully produced, Plato's Phaedo would make (...) an ideal gift and it should be a part of everyone's personal library. (shrink)

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.

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 ….

This chapter shows that the experimental philosophy has much to offer to philosophy of science by reviewing the existing experimental‐philosophy work in the philosophy of science and by defending it against an important criticism. A natural way of extending experimental philosophy methods to the philosophy of science is to survey scientists’ judgments. The chapter presents two projects in the philosophy of science that can benefit from such surveys: analyzing the scientific concepts found in particular scientific communities and studying scientific cognition. (...) It explains how surveying lay people's judgments can bear on issues in the philosophy of science. The chapter examines the possible contributions of bibliometric, ethnographic and cliometric methods to the philosophy of science. Ethnographic methods are particularly useful to study the social structure of science, the nature and role of social norms in the production of scientific knowledge, and the discovery heuristics at work in everyday scientific practice.

: While thought experiments play an important role in contemporary analytic philosophy, much remains unclear about thought experiments. In particular, it is still unclear whether the judgments elicited by thought experiments can provide evidence for the premises of philosophical arguments. This article argues that, if an influential and promising view about the nature of the judgments elicited by thought experiments is correct, then many thought experiments in philosophy fail to provide any evidence for the premises of philosophical arguments.

Many philosophers hold that experts’ semantic intuitions are more reliable and provide better evidence than lay people’s intuitions—a thesis commonly called “the Expertise Defense.” Focusing on the intuitions about the reference of proper names, this article critically assesses the Expertise Defense.

This edition of Martin Ostwald's revised version of J. B. Skemp's 1952 translation of _Statesman_ includes a new selected bibliography, as well as Ostwald's interpretive introduction, which traces the evolution in Plato's political philosophy from _Republic_ to _Statesman to Laws_--from philosopher-king to royal statesman.

A model for the ideal state includes discussions of the nature and application of justice, the role of the philosopher in society, the goals of education, and the effects of art upon character.

Although cognitive scientists have learned a lot about concepts, their findings have yet to be organized in a coherent theoretical framework. In addition, after twenty years of controversy, there is little sign that philosophers and psychologists are converging toward an agreement about the very nature of concepts.Doing without Concepts(Machery 2009) attempts to remedy this state of affairs. In this article, I review the main points and arguments developed at greater length inDoing without Concepts.

This article critically examines the contemporary resurgence of empiricism (or “neo-empiricism”) in philosophy, psychology, neuropsychology, and artificial intelligence. This resurgence is an important and positive development. It is the first time that this centuries-old empiricist approach to cognition is precisely formulated in the context of cognitive science and neuroscience. Moreover, neo-empiricists have made several findings that challenge amodal theories of concepts and higher cognition. It is argued, however, that the theoretical foundations of and the empirical evidence for neo-empiricism are not (...) as strong as is usually claimed by its proponents. The empirical evidence for and against neo-empiricism is discussed in detail. (shrink)

The defining insight of evolutionary psychology consists of bringing considerations drawn from evolutionary biology to bear on the study of human psychology. So characterized, evolutionary psychology encompasses a large range of views about the nature and evolution of human psychology as well as diverging opinions about the proper method for studying them.¹ In this article, I propose to clarify and evaluate various aspects of evolutionary psychologists’ methodology, with a special focus on their heuristics of discovery—i.e., their methods for developing plausible (...) hypotheses—and their strategies of confirmation—i.e., their methods for providing empirical support for these hypotheses.² I will also evaluate several well-known objections raised against evolutionary psychology. Note that because views about psychology and evolution differ among evolutionary psychologists, I do not pretend to cover every method used in evolutionary psychology.³. (shrink)

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

In this article, I focus on two claims made by Appiah in Experiments in Ethics: Doris’s and Harman’s criticism of virtue ethics fails, and moral psychology can be used to identify erroneous moral intuitions. I argue that both claims are erroneous.

In “Concepts Are Not a Natural Kind” (2005), I argued that the notion of concept in psychology and in neuropsychology fails to pick out a natural kind. Piccinini and Scott (2006, in this issue) have criticized the argument I used to support this conclusion. They also proposed two alternative arguments for a similar conclusion. In this reply, I rebut Piccinini and Scott’s main objection against the argument proposed in “Concepts Are Not a Natural Kind.” Moreover, I show that the two (...) alternative arguments de- veloped by Piccinini and Scott are not promising for supporting the conclusion that concepts are not a natural kind.

The question, ‘Is cognition linguistic?' divides recent cognitive theories into two antagonistic groups. Sententialists claim that we think in some language, while advocates of non linguistic views of cognition deny this claim. The Introspective Argument for Sententialism is one of the most appealing arguments for sententialism. In substance, it claims that the introspective fact of inner speech provides strong evidence that our thoughts are linguistic. This article challenges this argument. I claim that the Introspective Argument for Sententialism confuses the content (...) of our thoughts with their vehicles: while sententialism is a thesis about the vehicles of our thoughts, inner speech sentences are the content of auditory or articulatory images. The rebuttal of the introspective argument for sententialism is shown to have a general significance in cognitive science: Introspection does not tell us how we think. (shrink)

The title and blurb suggest that this book makes a case for eliminating concepts. The suggestion is misleading, however. What Machery really does is multiply them.Here is his characterization of what concepts are. He says that a concept is ‘a body of knowledge about x that is stored in long-term memory and that is used by default in the processes underlying most, if not all, higher cognitive competences when these processes result in judgements about x’. He holds that people represent (...) categories through exemplars, prototypes and theories, that these types of representations really exist, and that they all count as concepts according to the above characterization.Machery offers an interesting new take on the concept research undertaken by cognitive psychologists over the past three or four decades. Psychology textbooks tend to classify the main theories of concepts as follows. They draw a contrast between the ‘classical definition’ theory and late 20th century ‘probabilistic’ theories. They distinguish, within the probabilistic camp, between ‘prototype-based’ theories and ‘exemplar-based’ theories, and they admit a further family of ‘theory–theories’, according to which a concept of x is a mini-theory about x. Within each camp, different specific …. (shrink)

This chapter examines the folk concept of disease by assessing (1) whether disease judgments are influenced by whether a condition is typical, dysfunctional, and disvalued and (2) whether they are influenced by the causes and symptoms of a condition. Results tentatively suggest that the folk concept of disease is naturalistic (i.e., value judgments don’t seem to matter) and perhaps not essentially causal (symptoms are sufficient for a condition to be a disease) and that gender and disgust sensitivity influence disease judgment.
