We investigate claims about the frequency of "know" made by philosophers. Our investigation has several overlapping aims. First, we aim to show what is required to confirm or disconfirm philosophers’ claims about the comparative frequency of different uses of philosophically interesting expressions. Second, we aim to show how using linguistic corpora as tools for investigating meaning is a productive methodology, in the sense that it yields discoveries about the use of language that philosophers would have overlooked if they remained in (...) their "armchairs of an afternoon", to use J.L. Austin’s phrase. Third, we discuss facts about the meaning of "know" that so far have been ignored in philosophy, with the aim of reorienting discussions of the relevance of ordinary language for philosophical theorizing.

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)

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.

The “expertise defense” is the claim that philosophers have special expertise that allows them to resist the biases suggested by the findings of experimental philosophers. Typically, this defense is backed up by an analogy with expertise in science or other academic fields. Recently, however, studies have begun to suggest that philosophers' intuitions may be just as subject to inappropriate variation as those of the folk. Should we conclude that the expertise defense has been debunked? I'll argue that the analogy with (...) science still motivates a default assumption of philosophical expertise; however, the expertise so motivated is not expertise in intuition, and its existence would not suffice to answer the experimentalist challenge. I'll also suggest that there are deep parallels between the current methodological crisis in philosophy and the decline of introspection-based methods in psychology in the early twentieth century. The comparison can give us insight into the possible future evolution of philosophical methodology. (shrink)

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

The standard view of philosophical methodology is that philosophers rely on intuitions as evidence. Herman Cappelen argues that this claim is false: it is not true that philosophers rely extensively on intuitions as evidence. At worst, analytic philosophers are guilty of engaging in somewhat irresponsible use of 'intuition'-vocabulary. While this irresponsibility has had little effect on first order philosophy, it has fundamentally misled meta-philosophers: it has encouraged meta-philosophical pseudo-problems and misleading pictures of what philosophy is.

I address Sinnott-Armstrong's argument that evidence of framing effects in moral psychology shows that moral intuitions are unreliable and therefore not noninferentially justified. I begin by discussing what it is to be epistemically unreliable and clarify how framing effects render moral intuitions unreliable. This analysis calls for a modification of Sinnott-Armstrong's argument if it is to remain valid. In particular, he must claim that framing is sufficiently likely to determine the content of moral intuitions. I then re-examine the evidence which (...) is supposed to support this claim. In doing so, I provide a novel suggestion for how to analyze the reliability of intuitions in empirical studies. Analysis of the evidence suggests that moral intuitions subject to framing effects are in fact much more reliable than perhaps was thought, and that Sinnott-Armstrong has not succeeded in showing that noninferential justification has been defeated.

This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic features, and argue that it is essential to distinguish between their representational scope and representational target. We also examine (...) the characteristics of the communities who use these two types of models, including their research goals, disciplinary affiliations, and preferred practices to show how these have contributed to the conceptualization of a model organism. We conclude that model organisms are a specific subgroup of organisms that have been standardized to fit an integrative and comparative mode of research, and that it must be clearly distinguished from the broader class of experimental organisms. In addition, we argue that model organisms are the key components of a unique and distinctively biological way of doing research using models.Keywords: Experimental organism; Genetics; Model organism; Modeling; Philosophy of biology; Representation.

Abstract: Some proponents of “experimental philosophy” criticize philosophers' use of thought experiments on the basis of evidence that the verdicts vary with truth-independent factors. However, their data concern the verdicts of philosophically untrained subjects. According to the expertise defence, what matters are the verdicts of trained philosophers, who are more likely to pay careful attention to the details of the scenario and track their relevance. In a recent article, Jonathan M. Weinberg and others reply to the expertise defence that there (...) is no evidence for such expertise. They now receive a reply in this article, which argues that they have misconstrued the dialectical situation. Since they have produced no evidence that philosophical training is less efficacious for thought experimentation than for other cognitive tasks for which they acknowledge that it produces genuine expertise, such as informal argumentation, they have produced no evidence for treating the former more sceptically than the latter.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

Woodward's long awaited book is an attempt to construct a comprehensive account of causation explanation that applies to a wide variety of causal and explanatory claims in different areas of science and everyday life. The book engages some of the relevant literature from other disciplines, as Woodward weaves together examples, counterexamples, criticisms, defenses, objections, and replies into a convincing defense of the core of his theory, which is that we can analyze causation by appeal to the notion of manipulation.

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 book is a defense of the methods of analytic philosophy against a recent empirical challenge to the soundness of those methods. The challenge is raised by practitioners of “experimental philosophy” and concerns the extent to which analytic philosophy relies on intuition—in particular, the extent to which analytic philosophers treat intuitions as evidence in arguing for philosophical conclusions. Experimental philosophers say that analytic philosophers place a great deal of evidential weight on people’s intuitions about hypothetical cases and thought experiments. This (...) book argues that this view of traditional philosophical method is a myth, part of “metaphilosophical folklore.” Analytic philosophy makes regular use of hypothetical examples and thought experiments, but philosophers argue for their claims about what is true or not true in these examples and thought experiments. It is these arguments, not intuitions, that are treated as evidence for the claims. The book discusses xphi and some recent xphi studies; critiques a variety of other metaphilosophical claims; examines such famous arguments as Gettier’s refutation of the JTB theory and Kripke’s Gödel Case argument against descriptivism about proper names, and shows that they rely on reasoning rather than intuition; and finds existing critiques of xphi, the “Multiple Concepts” and “Expertise” replies, to be severely lacking.

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.

Inferences like these are known as extrapolations.

Recent experimental philosophy arguments have raised trouble for philosophers' reliance on armchair intuitions. One popular line of response has been the expertise defense: philosophers are highly-trained experts, whereas the subjects in the experimental philosophy studies have generally been ordinary undergraduates, and so there's no reason to think philosophers will make the same mistakes. But this deploys a substantive empirical claim, that philosophers' training indeed inculcates sufficient protection from such mistakes. We canvass the psychological literature on expertise, which indicates that people (...) are not generally very good at reckoning who will develop expertise under what circumstances. We consider three promising hypotheses concerning what philosophical expertise might consist in: (i) better conceptual schemata; (ii) mastery of entrenched theories; and (iii) general practical know-how with the entertaining of hypotheticals. On inspection, none seem to provide us with good reason to endorse this key empirical premise of the expertise defense. (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.

Through an examination of the actual research strategies and assumptions underlying the Human Genome Project (HGP), it is argued that the epistemic basis of the initial model organism programs is not best understood as reasoning via causal analog models (CAMs). In order to answer a series of questions about what is being modeled and what claims about the models are warranted, a descriptive epistemological method is employed that uses historical techniques to develop detailed accounts which, in turn, help to reveal (...) forms of reasoning that are explicit, or more often implicit, in the practice of a particular field of scientific study. It is suggested that a more valid characterization of the reasoning structure at work here is a form of case-based reasoning. This conceptualization of the role of model organisms can guide our understanding and assessment of these research programs, their knowledge claims and progress, and their limitations, as well as how we educate the public about this type of biomedical research.

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)

Avner Baz presents a critique of the working practices of analytic philosophy in recent decades. He challenges the assumptions on which the philosophical 'method of cases' rests, and he presents a pragmatist conception of language on which the method of cases as used both 'armchair' and 'experimental' philosophers is fundamentally misguided.

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

In this article, we discuss critically some of the key themes in Max Deutsch’s excellent book, The Myth of the Intuitive. We focus in particular on the shortcomings of his historical analysis – a missed opportunity by our lights, on the claim that philosophers present arguments in support of the judgments elicited by thought experiments, and on the claim that experimental philosophy is only relevant for the methodology of philosophy if thought experiments elicit intuitions.
