In this paper I consider the plausibility of developing anti-skepticism by framing the question in linguistic terms: instead of asking whether we know, we ask what falls within the extension of the word “know”. I first trace two previous attempts to develop anti-skepticism in this way, from Austin (particularly as presented by Kaplan) and from epistemic contextualism, and I present reasons to think that both approaches are unsuccessful. I then focus on a recently popular attempt to develop anti-skepticism from the (...) “function-first” approach associated with Craig, which I also show to be problematic. I then argue that the apparent prima facie plausibility of fighting skepticism on linguistic grounds is due to a methodological spill-over from linguistics. Once we recognize this, it becomes clear that the skepticism debate should not be conducted in linguistic terms. (shrink)

In this paper I use insights from exploratory analyses on large English language corpora to consider the extent to which there is a widely-used ordinary notion of justification that attaches to beliefs. I will show that this has ramifications for one broad approach to theorising about justification – the folk justification approach. I will argue that the corpus-based findings presented pose a challenge to the folk justification approach insofar as they suggest that “justify” is not widely-used talk about the justification (...) of our beliefs. I will conclude by presenting the possible solutions to this challenge, and remarking on their feasibility. (shrink)

Philosophers are often credited with particularly well-developed conceptual skills. The ‘expertise objection’ to experimental philosophy builds on this assumption to challenge inferences from findings about laypeople to conclusions about philosophers. We draw on psycholinguistics to develop and assess this objection. We examine whether philosophers are less or differently susceptible than laypersons to cognitive biases that affect how people understand verbal case descriptions and judge the cases described. We examine two possible sources of difference: Philosophers could be better at deploying concepts, (...) and this could make them less susceptible to comprehension biases (‘linguistic expertise objection’). Alternatively, exposure to different patterns of linguistic usage could render philosophers vulnerable to a fundamental comprehension bias, the linguistic salience bias, at different points (‘linguistic usage objection’). Together, these objections mount a novel ‘master argument’ against experimental philosophy. To develop and empirically assess this argument, we employ corpus analysis and distributional semantic analysis and elicit plausibility ratings from academic philosophers and psychology undergraduates. Our findings suggest philosophers are better at deploying concepts than laypeople but are susceptible to the linguistic salience bias to a similar extent and at similar points. We identify methodological consequences for experimental philosophy and for philosophical thought experiments. (shrink)

Plausibly, how much is at stake in some salient practical task can affect how generously people ascribe knowledge of task-relevant facts. There is a metaphysical puzzle about this phenomenon, and an empirical puzzle. Metaphysically: there are competing theories about when and how practical stakes affect whether it is correct to ascribe knowledge. Which of these theories is the right one? Empirically: experimental philosophy has struggled to find a stakes-effect on people’s knowledge ascriptions. Is the alleged phenomenon just a philosopher’s fantasy? (...) I propose a new psychological account of when and why people’s knowledge ascriptions are sensitive to stakes. My hypothesis is motivated by empirical research on how people’s judgements are sensitive to their social context. Specifically, people’s evaluations are sensitive to their ‘psychological distance’ from the scenarios they are considering. When using ‘fixed-evidence probes’, experimental philosophy has found that what’s at stake for a fictional character in a made-up scenario has little or no effect on how participants ascribe knowledge to them. My hypothesis predicts this finding: the scenarios are too ‘psychologically distant’ to participants. Our empirical puzzle is resolved: the stakes-effect often present in the wild won’t be present in vignette studies. (This illustrates a widespread problem with X-phi vignette studies: if people might judge differently in other social contexts, we can’t generalize from the results of these experiments. That is, vignette studies are of doubtful ‘external validity’.) The hypothesis also resolves our metaphysical puzzle. It predicts that people do not ascribe knowledge in a way deemed correct by any of the standard philosophical views, namely classical invariantism, interest-relative invariantism, and contextualism. Our knowledge ascriptions shift around in the way that’s most useful for social beings like us, and this pattern in our judgements can only be endorsed by a genuinely relativist metaphysics for knowledge.

Research on children's theory of mind often restricts conceptually meaningful talk about knowledge to instances where know references a corresponding mental state. This article offers a reappraisal of that view. From a social-pragmatic perspective, even nonreferential talk is meaningful when appropriately embedded in social routines. A synthesis of corpus data suggests children's early talk about knowledge routinely occurs in question–answer contexts. It is argued that the influence of interrogative contexts is evident in children's over-attributions of knowledge when someone is only (...) guessing. This influence is taken as evidence for the role of linguistic practices in shaping the concept of knowledge. (shrink)

I am grateful for Joshua Alexander and Jonathan Weinberg’s, Avner Baz’s and Max Deutsch’s insightful comments on Philosophy Within Its Proper Bounds. I have learned a lot thinking about them, identifying points of convergence and places where differences remain unbridgeable and trying to address the most pressing criticisms. In what follows, I will engage their commentaries in turn.

Critics across the political spectrum have worried that ordinary uses of words like ‘racist’, ‘sexist’, and ‘homophobic’ are becoming conceptually inflated, meaning that these expressions are getting used so widely that they lose their nuance and, thereby, their moral force. However, the charge of conceptual inflation as well as responses to it are standardly made without any systematic investigation of how ‘racist’ and other expressions condemning oppression are actually used in ordinary language. Once we examine large linguistic corpora to see (...) how these expressions are actually used, we find that English speakers have a rich linguistic repertoire for qualifying the degree to which and dimensions along which something is racist, sexist, homophobic, and so on. These facts about ordinary usage undermine the charge of conceptual inflation. Without awareness of facts about ordinary usage, theorists risk making linguistic prescriptions that are unnecessary or counterproductive. (shrink)

Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...) with pupillometry to document this “salience bias.” We find that under certain conditions, competent speakers automatically make stereotypical inferences they know to be inappropriate.

Research in experimental philosophy has increasingly been turning to corpus methods to produce evidence for empirical claims, as they open up new possibilities for testing linguistic claims or studying concepts across time and cultures. The present article reviews the quasi-experimental studies that have been done using textual data from corpora in philosophy, with an eye for the modeling and experimental design that enable statistical inference. I find that most studies forego comparisons that could control for confounds, and that only a (...) little less than half employ statistical testing methods to control for chance results. Furthermore, at least some researchers make modeling decisions that either do not take into account the nature of corpora and of the word-concept relationship, or undermine the experiment's capacity to answer research questions. I suggest that corpus methods could both provide more powerful evidence and gain more mainstream acceptance by improving their modeling practices. (shrink)

There is, in my view, a striking combination in Édouard Machery’s Philosophy Within Its Proper Bounds of philosophical modesty and philosophical presumptiveness. Its call upon philosophers to give up their ambitious pursuits of metaphysical necessities, or essences, and to content themselves instead with the elucidation or analysis of our concepts, is made from within a pre-Kantian framework that takes the world expressed in human discourse and captured in our concepts to be a world as it is in itself, altogether independent (...) of how it comes into view in our discursive practices. And this, I will propose, means that Machery’s critique of much of the work that has been carried out within mainstream analytic philosophy in the last few decades, as well as his proposal for philosophical reform, end up partaking in what has been most fundamentally problematic about that work.

The fact that Gilbert Ryle and J.L. Austin seem to disagree about the ordinary use of words such as ‘voluntary’, ‘involuntary’, ‘voluntarily’, and ‘involuntarily’ has been taken to cast doubt on the methods of ordinary language philosophy. As Benson Mates puts the worry, ‘if agreement about usage cannot be reached within so restricted a sample as the class of Oxford Professors of Philosophy, what are the prospects when the sample is enlarged?’ (Mates 1958, p. 165). In this chapter, we evaluate (...) Mates’s criticism alongside Ryle’s and Austin’s specific claims about the ordinary use of these words, assessing these claims against actual examples of ordinary use drawn from the British National Corpus (BNC). Our evaluation consists in applying a combination of methods: first aggregating judgments about a large set of samples drawn from the corpus, and then using a clustering algorithm to uncover connections between different types of use. In applying these methods, we show where and to what extent Ryle’s and Austin’s accounts of the use of the target terms are accurate as well as where they miss important aspects of ordinary use, and we demonstrate the usefulness of this new combination of methods. At the heart of our approach is a commitment to the idea that systematically looking at actual uses of expressions is an essential component of any approach to ordinary language philosophy. (shrink)
