Testimony is an invaluable source of knowledge. We rely on the reports of those around us for everything from the ingredients in our food and medicine to the identity of our family members. Recent years have seen an explosion of interest in the epistemology of testimony. Despite the multitude of views offered, a single thesis is nearly universally accepted: testimonial knowledge is acquired through the process of transmission from speaker to hearer. In this book, Jennifer Lackey shows that this thesis (...) is false and, hence, that the literature on testimony has been shaped at its core by a view that is fundamentally misguided. She then defends a detailed alternative to this conception of testimony: whereas the views currently dominant focus on the epistemic status of what speakers believe, Lackey advances a theory that instead centers on what speakers say. The upshot is that, strictly speaking, we do not learn from one another's beliefs - we learn from one another's words. Once this shift in focus is in place, Lackey goes on to argue that, though positive reasons are necessary for testimonial knowledge, testimony itself is an irreducible epistemic source. This leads to the development of a theory that gives proper credence to testimony's epistemologically dual nature: both the speaker and the hearer must make a positive epistemic contribution to testimonial knowledge. The resulting view not only reveals that testimony has the capacity to generate knowledge, but it also gives appropriate weight to our nature as both socially indebted and individually rational creatures. The approach found in this book will, then, represent a radical departure from the views currently dominating the epistemology of testimony, and thus is intended to reshape our understanding of the deep and ubiquitous reliance we have on the testimony of those around us.

Many epistemologists agree that even very young children sometimes acquire knowledge through testimony. In this paper I address two challenges facing this view. The first (building on a point made in Lackey (2005)) is the defeater challenge, which is to square the hypothesis that very young children acquire testimonial knowledge with the fact that children (whose cognitive immaturity prevents them from having or appreciating reasons) cannot be said to satisfy the No-Defeaters condition on knowledge. The second is the extension challenge, (...) which is to give a motivated, extensionally-adequate account of the conditions on testimonial knowledge in early childhood. Neither challenge can be met merely by endorsing externalism about knowledge; but we can meet both by reconceiving the process that eventuates in the child’s consumption of testimony. My central thesis is that this process should be seen as implicating features of the child's social environment. The result is a novel anti-individualistic externalism about knowledge. (shrink)

According to Interest-Relative Invariantism, whether an agent knows that p, or possesses other sorts of epistemic properties or relations, is in part determined by the practical costs of being wrong about p. Recent studies in experimental philosophy have tested the claims of IRI. After critically discussing prior studies, we present the results of our own experiments that provide strong support for IRI. We discuss our results in light of complementary findings by other theorists, and address the challenge posed by a (...) leading intellectualist alternative to our view.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription can seem true (...) in one conversational context but false in another. This purported fact about people’s intuitions serves as one of the main pieces of evidence for epistemic contextualism. (shrink)

In this paper I defend the theory that knowledge is credit-worthy true belief against a family of objections, one of which was leveled against it in a recent paper by Jennifer Lackey. In that paper, Lackey argues that testimonial knowledge is problematic for the credit-worthiness theory because when person A comes to know that p by way of the testimony of person B, it would appear that any credit due to A for coming to believe truly that p belongs to (...) the testifier, B, rather than the hearer, A. If so, then knowledge would appear not to be a matter of credit for true belief. I think that the problem this raises actually has little to do with the fact that the knowledge comes by way of testimony, and that similar objections can be formulated in terms of perceptual and memorial knowledge. I will attempt to neutralize these objections by drawing a distinction between credit as praiseworthiness and credit as attributability. (shrink)

Judging by our folk appraisals, then, knowledge and action are intimately related. The theories of rational action with which we are familiar leave this unexplained. Moreover, discussions of knowledge are frequently silent about this connection. This is a shame, since if there is such a connection it would seem to constitute one of the most fundamental roles for knowledge. Our purpose in this paper is to rectify this lacuna, by exploring ways in which knowing something is related to rationally acting (...) upon it, defending one particular proposal against anticipated objections.

Knowledge and Lotteries is organized around an epistemological puzzle: in many cases, we seem consistently inclined to deny that we know a certain class of propositions, while crediting ourselves with knowledge of propositions that imply them. In its starkest form, the puzzle is this: we do not think we know that a given lottery ticket will be a loser, yet we normally count ourselves as knowing all sorts of ordinary things that entail that its holder will not suddenly acquire a (...) large fortune. After providing a number of specific and general characterizations of the puzzle, Hawthorne carefully examines the competing merits of candidate solutions. In so doing, he explores a number of central questions concerning the nature and importance of knowledge, including the relationship of knowledge to assertion and practical reasoning, the status of epistemic closure principles, the merits of various brands of scepticism, the prospects for a contextualist account of knowledge, and the potential for other sorts of salience-sensitive accounts. Along the way, he offers a careful treatment of pertinent issues at the foundations of semantics. His book will be of interest to anyone working in the field of epistemology, as well as to philosophers of language. (shrink)

In this paper, I give an answer to the central epistemic question regarding the normative requirements for beliefs based on testimony. My suggestion here is that our best strategy for coming up with the conditions for justification is to look at cases where the adoption of the belief matters to the person considering it. This leads me to develop, in Part One of the paper, an interest-relative theory of justification, according to which our justification for a proposition p depends on (...) our evidence in favour of p in proportion to our interest in p, as signalled by the epistemic risk we take in believing that p is true. In Part Two, I argue that this theory shows that the reductivist view offers a better normative account for the epistemic status of beliefs based on testimony than the credulist one, but it is inaptly named; the view I develop here is better conceived of as The Dependence Account.

One recent trend in contemporary epistemology is to study the way in which the concept of knowledge is actually applied in everyday settings. This approach has inspired an exciting new spirit of collaboration between experimental philosophers and traditional epistemologists, who have begun using the techniques of the social sciences to investigate the factors that influence ordinary judgments about knowledge attribution. This paper provides an overview of some of the results these researchers have uncovered, suggesting that in addition to traditionally considered (...) factors like evidence and justification, a number of important non-truth-conducive factors play significant roles in determining when people ascribe knowledge. The present review focuses on four non-traditional factors: pragmatic load (in relation to contextualism and interest-relative invariantism), moral judgment, performance errors, and demographic variation.

Recent theories of epistemic contextualism have challenged traditional invariantist positions in epistemology by claiming that the truth conditions of knowledge attributions fluctuate between conversational contexts. Contextualists often garner support for this view by appealing to folk intuitions regarding ordinary knowledge practices. Proposed is an experiment designed to test the descriptive conditions upon which these types of contextualist defenses rely. In the cases tested, the folk pattern of knowledge attribution runs contrary to what contextualism predicts. While preliminary, these data inspire prima (...) facie skepticism for the contextualist hypothesis regarding folk knowledge claims, as well as challenge certain predictions made by recent theories of subject-sensitive invariantism. It is further argued that such results raise methodological questions concerning the practice of relying on an assumption of intuitions, with respect to ordinary language practices, as evidence for philosophical conclusions regarding knowledge.

I will ask the conditional question: if folk attributions of "know" are not sensitive to the stakes and/or the salience of error, does this cast doubt on contextualism or subject-sensitive invariantism (SSI)? I argue that if it should turn out that folk attributions of knowledge are insensitive to such factors, then this undermines contextualism, but not SSI. That is not to say that SSI is invulnerable to empirical work of any kind. Rather, I defend the more modest claim that leading (...) versions of SSI are not undermined by one particular kind of experimental result, namely the recent suggestion that knowledge attributions are insensitive to the stakes.

Research in experimental epistemology has revealed a great, yet unsolved mystery: why do ordinary evaluations of knowledge ascribing sentences involving stakes and error appear to diverge so systematically from the predictions professional epistemologists make about them? Two recent solutions to this mystery by Keith DeRose (2011) and N. Ángel Pinillos (2012) argue that these differences arise due to specific problems with the designs of past experimental studies. This paper presents two new experiments to directly test these responses. Results vindicate previous (...) findings by suggesting that (i) the solution to the mystery is not likely to be based on the empirical features these theorists identify, and (ii) that the salience of ascriber error continues to make the difference in folk ratings of third-person knowledge ascribing sentences.

This paper concerns the philosophical significance of a choice about how to design the context shifting experiments used by contextualists and anti-intellectualists: Should contexts be judged jointly, with contrast, or separately, without contrast? Findings in experimental psychology suggest (1) that certain contextual features are more difficult to evaluate when considered separately, and there are reasons to think that one feature--stakes or importance--that interests contextualists and anti-intellectualists is such a difficult to evaluate attribute, and (2) that joint evaluation of contexts can (...) yield judgments that are more reflective and rational in certain respects. With those two points in mind, a question is raised about what source of evidence provides better support for philosophical theories of how contextual features affect knowledge ascriptions and evidence: Should we prefer evidence consisting of "ordinary" judgments, or more reflective, perhaps more rational judgments? That question is answered in relation to different accounts of what such theories aim to explain, and it is concluded that evidence from contexts evaluated jointly should be an important source of evidence for contextualist and anti-intellectualist theories, a conclusion that is at odds with the methodology of some recent studies in experimental epistemology.
