Defenders of pragmatic encroachment in epistemology (or what I call practicalism) need to address two main problems. First, the view seems to imply, absurdly, that knowledge can come and go quite easily—in particular, that it might come and go along with our variable practical interests. We can call this the stability problem. Second, there seems to be no fully satisfying way of explaining whose practical interests matter. We can call this the “whose stakes?” problem. I argue that both problems can (...) be addressed in roughly the same terms. More exactly, I argue that by first clarifying the whose stakes? problem an answer to the stability problem naturally falls out. (shrink)

I consider the problem of how to derive what an agent believes from their credence function and utility function. I argue the best solution of this problem is pragmatic, i.e. it is sensitive to the kinds of choices actually facing the agent. I further argue that this explains why our notion of justified belief appears to be pragmatic, as is argued e.g. by Fantl and McGrath. The notion of epistemic justification is not really a pragmatic notion, but it is being (...) applied to a pragmatically defined concept, i.e. belief. (shrink)

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a (...) number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (shrink)

Jason Stanley's "Knowledge and Practical Interests" is a brilliant book, combining insights about knowledge with a careful examination of how recent views in epistemology fit with the best of recent linguistic semantics. Although I am largely convinced by Stanley's objections to epistemic contextualism, I will try in what follows to formulate a version that might have some prospect of escaping his powerful critique.

Is it harder to acquire knowledge about things that really matter to us than it is to acquire knowledge about things we don't much care about? Jason Stanley 2005 argues that whether or not the relational predicate 'knows that' holds between an agent and a proposition can depend on the practical interests of the agent: the more it matters to a person whether p is the case, the more justification is required before she counts as knowing that p. The evidence (...) for Stanley's thesis includes a number of intuitive judgments about examples. In this paper we provide parallel examples for which Stanley's thesis requires unwelcome knowledge-attributions, and argue that this is possible because his thesis conflicts with familiar and plausible principles about knowledge.

This article explores the relationship between pragmatic encroachment and epistemic permissiveness. If the suggestion that all epistemic notions are interest-relative is viable , then it seems that a certain species of epistemic permissivism must be viable as well. For, if all epistemic notions are interest relative then, sometimes, parties in paradigmatic cases of shared evidence can be maximally rational in forming competing basic doxastic attitudes towards the same proposition. However, I argue that this total pragmatic encroachment is not tenable, and, (...) thus, epistemic permissivism cannot be vindicated in this way. (shrink)

Why do our intuitive knowledge ascriptions shift when a subject's practical interests are mentioned? Many efforts to answer this question have focused on empirical linguistic evidence for context sensitivity in knowledge claims, but the empirical psychology of belief formation and attribution also merits attention. The present paper examines a major psychological factor (called ?need-for-closure?) relevant to ascriptions involving practical interests. Need-for-closure plays an important role in determining whether one has a settled belief; it also influences the accuracy of one's cognition. (...) Given these effects, it is a mistake to assume that high- and low-stakes subjects provided with the same initial evidence are perceived to enjoy belief formation that is the same as far as truth-conducive factors are concerned. This mistaken assumption has underpinned contextualist and interest-relative invariantist treatments of cases in which contrasting knowledge ascriptions are elicited by descriptions of subjects with the same initial information and different stakes. The paper argues that intellectualist invariantism can easily accommodate such cases. (shrink)

The goal of this paper is to defend Simple Modest Invariantism (SMI) about knowledge from the threat presented by pragmatic encroachment. Pragmatic encroachment is the view that practical circumstances are relevant in some way to the truth of knowledge ascriptions—and if this is true, it would entail the falsity of SMI. Drawing on Ross and Schroeder’s recent Reasoning Disposition account of belief, I argue that the Reasoning Disposition account, together with Grice’s Maxims, gives us an attractive pragmatic account of the (...) connection between knowledge ascriptions and practical circumstances. This gives us the ability to explain away the data that is supposed to support pragmatic encroachment. Finally, I address three important objections to the view offered by giving a pragmatic account of when it is conversationally appropriate to cancel a conversational implicature, and discussing when sentences with true content can end up sounding false as well as cases where sentences with false content can end up sounding true.

According to the Dogmatism Puzzle, knowledge breeds dogmatism: if a subject knows a proposition h, then she is justified in disregarding any future evidence against h, for she knows that such evidence is misleading. The standard, widely accepted, solution to the puzzle appeals to the defeasibility of knowledge. I argue that the defeat solution leaves intact a residual dogmatist puzzle. Solving this puzzle requires proponents of defeat to deny a plausible principle that the original puzzle relies on called Entitlement, a (...) principle stating roughly that knowing that a piece of evidence is misleading entitles one to disregard it. The plausibility of Entitlement should cast doubt not only on the defeat solution, but on an assumption that has often been taken for granted: the falsity of the dogmatist conclusion of the original puzzle. I conclude that we face a dilemma between giving up Entitlement and living with dogmatism. (shrink)

Recent authors have drawn attention to a new kind of defeating evidence commonly referred to as higher-order evidence. Such evidence works by inducing doubts that one’s doxastic state is the result of a flawed process – for instance, a process brought about by a reason-distorting drug. I argue that accommodating defeat by higher-order evidence requires a two-tiered theory of justification, and that the phenomenon gives rise to a puzzle. The puzzle is that at least in some situations involving higher-order defeaters (...) the correct epistemic rules issue conflicting recommendations. For instance, a subject ought to believe p, but she ought also to suspend judgment in p. I discuss three responses. The first resists the puzzle by arguing that there is only one correct epistemic rule, an Über-rule. The second accepts that there are genuine epistemic dilemmas. The third appeals to a hierarchy or ordering of correct epistemic rules. I spell out problems for all of these responses. I conclude that the right lesson to draw from the puzzle is that a state can be epistemically rational or justified even if one has what looks to be strong evidence to think that it is not. As such, the considerations put forth constitute a non question-begging argument for a kind of externalism. (shrink)

Keith DeRose has argued that the two main problems facing subject-sensitive invariantism come from the appropriateness of certain third-person denials of knowledge and the inappropriateness of now you know it, now you don't claims. I argue that proponents of SSI can adequately address both problems. First, I argue that the debate between contextualism and SSI has failed to account for an important pragmatic feature of third-person denials of knowledge. Appealing to these pragmatic features, I show that straightforward third-person denials are (...) inappropriate in the relevant cases. And while there are certain denials that are appropriate, they pose no problems for SSI. Next, I offer an explanation, compatible with SSI, of the oddity of now you know it, now you don't claims. To conclude, I discuss the intuitiveness of purism, whose rejection is the source of many problems for SSI. I propose to explain away the intuitiveness of purism as a side-effect of the narrow focus of previous epistemological inquiries. (shrink)

Jennifer Lackey challenges the sufficiency version of the knowledge-action principle, viz., that knowledge that p is sufficient to rationally act on p, by proposing a set of alleged counterexamples. Her aim is not only to attack the knowledge-action principle, but also to undermine an argument for subject-sensitive invariantism. Lackey holds that her examples are counterexamples to the sufficiency version of the knowledge-action principle because (a) S knows the proposition in question, but (b) it is not rational for S to act (...) on it. In this paper, first, I argue against (a) on intuitive and on theoretical grounds. Second, I point out that (b), even if combined with (a), is not sufficient to make for counterexamples to the knowledge-action principle of the relevant kind. Third, I offer two alternative explanations of the intuition Lackey relies on. If either one of them is right, (b) may not be satisfied in her examples. (shrink)

We develop a novel challenge to pragmatic encroachment. The significance of belief-desire psychology requires treating questions about what to believe as importantly prior to questions about what to do; pragmatic encroachment undermines that priority, and therefore undermines the significance of belief-desire psychology. This, we argue, is a higher cost than has been recognized by epistemologists considering embracing pragmatic encroachment.

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)

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence.

This paper presents a partial analysis of perceptual knowledge, an analysis that will, I hope, lay a foundation for a general theory of knowing. Like an earlier theory I proposed, the envisaged theory would seek to explicate the concept of knowledge by reference to the causal processes that produce (or sustain) belief. Unlike the earlier theory, however, it would abandon the requirement that a knower's belief that p be causally connected with the fact, or state of affairs, that p.

Evidentialism is the thesis that epistemic justification for belief supervenes on evidential support. However, we claim there are cases in which, even though two subjects have the same evidential support for a proposition, only one of them is justified. What make the difference are pragmatic factors, factors having to do with our cares and concerns. Our argument against evidentialism is not based on intuitions about particular cases. Rather, we aim to provide a theoretical basis for rejecting evidentialism by defending a (...) “pragmatic” necessary condition on epistemic justification. We argue for the following necessary condition for justification: S is justified in believing that p only if S is rational to prefer (and, hence, act) as if p. In light of this necessary condition, the price of evidentialism is skepticism, or something close to it. (shrink)

We argue that a certain version of pragmatic encroachment, according to which one knows that p only if one’s epistemic position with respect to p is practically adequate, has a problematic consequence: one can lose knowledge that p by getting evidence for p, and conversely, one can gain knowledge that p by getting evidence against p. We first describe this version of pragmatic encroachment, and then we defend that it has the problematic consequence. Finally, we deal with a worry that (...) the consequence we find problematic is not, in fact, problematic. (shrink)

A general and fundamental tension surrounds our concept of what is said. On the one hand, what is said (asserted, claimed, stated, etc.) by utterances of a significant range of sentences is highly context sensitive. More specifically, (Observation 1 (O1)), what these sentences can be used to say depends on their contexts of utterance. On the other hand, speakers face no difficulty whatsoever in using many of these sentences to say (or make) the exact same claim, assertion, etc., across a (...) wide array of contexts. More specifically, (Observation 2 (O2)), many of the sentences in support of (O1) can be used to express the same thought, the same proposition, across a wide range of different contexts. (shrink)

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. (shrink)

According to a prominent claim in recent epistemology, people are less likely to ascribe knowledge to a high stakes subject for whom the practical consequences of error are severe, than to a low stakes subject for whom the practical consequences of error are slight. We offer an opinionated "state of the art" on experimental research about the role of stakes in knowledge judgments. We draw on a first wave of empirical studies--due to Feltz & Zarpentine (2010), May et al (2010), (...) and Buckwalter (2010)--which cast doubt on folk stakes sensitivity, and a second wave of empirical studies--due to Pinillos (2012) and Sripada & Stanley (2012)--said to vindicate it, as well as new studies of our own. We conclude that the balance of evidence to date best supports Folk stakes insensitivity, or that all else equal, stakes do not affect knowledge ascription. (shrink)

One prominent argument for pragmatic encroachment (PE) is that PE is entailed by a combination of a principle that states that knowledge warrants proper practical reasoning, and judgments that it is more difficult to reason well when the stakes go up. I argue here that this argument is unsuccessful. One problem is that empirical tests concerning knowledge judgments in high-stakes situations only sometimes exhibit the result predicted by PE. I argue here that those judgments that appear to support PE are (...) better interpreted not as judgments that the epistemic demands for knowing increase as one’s practical situation becomes more demanding, but instead as judgments reflecting a different kind of normative epistemic evaluation, namely whether one is acting in an epistemically responsible way. The general idea is that when someone treats a proposition as a reason for acting we can evaluate them epistemically both in terms of whether they know that proposition, as well as in terms of whether they are acting on their knowledge in the right kind of way. My charge against the PE proponent, then, is that she is interpreting judgments that are indicative of whether we are adhering to certain normative epistemic requirements generally as being indicative of whether we have knowledge specifically. There are, however, normative epistemic requirements that make demands of us that are indicative of something other than our possession of knowledge. (shrink)

The subject of this paper, Excuses, is one not to be treated, but only to be introduced, within such limits. It is, or might be, the name of a whole branch, even a ramiculated branch, of philosophy, or at least of one fashion of philosophy. I shall try, therefore, first to state what the subject is, why it is worth studying, and how it may be studied, all this at a regrettably lofty level: and then I shall illustrate, in more (...) congenial but desultory detail, some of the methods to be used, together with their limitations, and some of the unexpected results to be expected and lessons to be learned. Much, of course, of the amusement, and of the instruction, comes in drawing the coverts of the microglot, in hounding down the minutiae, and to this I can do no more here than incite you. But I owe it to the subject to say, that it has long afforded me what philosophy is so often thought, and made, barren of -- the fun of discovery, the pleasures of co-operation, and the satisfaction of reaching agreement.

Pragmatic encroachment offers a picture of knowledge whereby knowledge is unstable. This paper argues that pragmatic encroachment is committed to more instability than has been hitherto noted. One surprising result of the arguments in this paper is that pragmatic encroachment is not merely about changes in stakes. All sorts of practical factors can make for the presence or absence of knowledge on this picture stakes-sensitivity’ is misleading. Furthermore, insufficient attention has been paid to the variety of ways in which on (...) this view pragmatic factors affect knowledge: pragmatic factors are not merely knowledge-depriving but are also knowledge-inducing.

Human beings naturally desire knowledge. But what is knowledge? Is it the same as having an opinion? Highlighting the major developments in the theory of knowledge from Ancient Greece to the present day, Jennifer Nagel uses a number of simple everyday examples to explore the key themes and current debates of epistemology.

Knowledge ascriptions are a central topic of research in both philosophy and science. In this collection of new essays on knowledge ascriptions, world class philosophers offer novel approaches to this long standing topic.

Recently, some philosophers have defended the idea that knowledge is an interest-relative notion. According to this thesis, whether an agent knows P may depend on the practical costs of her being wrong about P. This perspective marks a radical departure from traditional accounts that take knowledge to be a purely intellectual concept. I think there is much to say on behalf of the interest-relative notion. In this paper, I report on some new evidence which strongly suggests that ordinary people’s attributions (...) of knowledge are in fact sensitive to practical interests. This is noteworthy because recent experiments have been interpreted by many to support the opposite conclusion. I also argue that the new results support an invariantist but interest-relativist account of knowledge, a thesis known as Interest Relative Invariantism (IRI). I do not make the case here that IRI gives us the very best explanation of the results presented here. Any such attempt would require an in-depth survey of the last few decades of work in epistemology. I only want to argue here that IRI gives us a simple and elegant explanation of the new data, and that the same cannot be said about traditional contextualism, a leading competitor to IRI. (shrink)
