I consider but reject one broad strategy for answering the threshold problem for fallibilist accounts of knowledge, namely what fixes the degree of probability required for one to know? According to the impurist strategy to be considered, the required degree of probability is fixed by one's practical reasoning situation. I distinguish two different ways to implement the suggested impurist strategy. According to the Relevance Approach, the threshold for a subject to know a proposition at a time is determined by the (...) practical reasoning situations she is then in to which that particular proposition is relevant. According to the Unity Approach, the threshold for a subject to know any proposition whatsoever at a time is determined by a privileged practical reasoning situation she then faces, most plausibly the highest stakes practical reasoning situation she is then in. I argue that neither way of implementing the impurist strategy succeeds and so impurism does not offer a satisfactory response to the threshold problem. (shrink)

Fallibilists claim that one can know a proposition on the basis of evidence that supports it even if the evidence doesn't guarantee its truth. Jessica Brown offers a compelling defence of this view against infallibilists, who claim that it is contradictory to claim to know and yet to admit the possibility of error.

There is a sceptical puzzle according to which knowledge appears to license an unacceptable kind of dogmatism. Here is a version of the corresponding sceptical argument: (1) If a subject S knows a proposition p, then it is OK for S to ignore all evidence against p as misleading; (2) It is never OK for any subject to ignore any evidence against their beliefs as misleading; (3) Hence, nobody knows anything.I distinguish between different versions of the puzzle (mainly a ‘permissibility’ (...) version and a ‘closure’ version) and offer a solution for one version (the permissibility version) of the problem. No matter how much a subject knows, knowledge never gives one a license to ignore evidence against a proposition. Premise (1) of the argument is false and the puzzle can thus be resolved. (shrink)

Historical patterns of discrimination seem to present us with conflicts between what morality requires and what we epistemically ought to believe. I will argue that these cases lend support to the following nagging suspicion: that the epistemic standards governing belief are not independent of moral considerations. We can resolve these seeming conflicts by adopting a framework wherein standards of evidence for our beliefs to count as justified can shift according to the moral stakes. On this account, believing a paradigmatically racist (...) belief reflects a failure to not only attend to the epistemic risk of being wrong, but also a failure to attend to the distinctively moral risk of wronging others given what we believe.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Defenses of pragmatic encroachment commonly rely on two thoughts: first, that the gap between one’s strength of epistemic position on p and perfect strength sometimes makes a difference to what one is justified in doing, and second, that the higher the stakes, the harder it is to know. It is often assumed that these ideas complement each other. This chapter shows that these ideas are far from complementary. Along the way, a variety of strategies for regimenting the somewhat inchoate notion (...) of stakes are indicated, and some troubling cases for pragmatic encroachment raised. (shrink)

ABSTRACTAccording to the Dogmatism Puzzle presented by Gilbert Harman, knowledge induces dogmatism because, if one knows that p, one knows that any evidence against p is misleading and therefore one can ignore it when gaining the evidence in the future. I try to offer a new solution to the puzzle by explaining why the principle is false that evidence known to be misleading can be ignored. I argue that knowing that some evidence is misleading doesn't always damage the credential of (...) the evidence, and therefore it doesn't always entitle one to ignore it. I also explain in what kind of cases and to what degree such knowledge allows one to ignore evidence. Hopefully, through the discussion, we can not only understand better where the dogmatism puzzle goes wrong, but also understand better in what sense rational believers should rely on their evidence and when they can ignore it.

In discussions of whether and how pragmatic considerations can make a difference to what one ought to believe, two sets of cases feature. The first set, which dominates the debate about pragmatic reasons for belief, is exemplified by cases of being financially bribed to believe (or withhold from believing) something. The second set, which dominates the debate about pragmatic encroachment on epistemic justification, is exemplified by cases where acting on a belief rashly risks some disastrous outcome if the belief turns (...) out to be false. Call those who think that pragmatic considerations make a difference to what one ought to believe in the second kind of case, but not in the first, ‘moderate pragmatists’. Many philosophers – in particular, most advocates of pragmatic and moral encroachment – are moderate pragmatists. But moderate pragmatists owe us an explanation of exactly why the second kind of pragmatic consideration makes a difference, but the first kind doesn’t. I argue that the most promising of these explanations all fail: they are either theoretically undermotivated, or get key cases wrong, or both. Moderate pragmatism may be an unstable stopping point between a more extreme pragmatism, on one hand, and an uncompromising anti-pragmatism on the other. (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'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.

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence. (shrink)

Does knowledge depend in any interesting way on our practical interests? This is the central question in the pragmatic encroachment debate. Pragmatists defend the affirmative answer to this question while purists defend the negative answer. The literature contains two kinds of arguments for pragmatism: principle-based arguments and case-based arguments. Principle-based arguments derive pragmatism from principles that connect knowledge to practical interests. Case-based arguments rely on intuitions about cases that differ with respect to practical interests. I argue that there are insurmountable (...) problems for both kinds of arguments, and that it is therefore unclear what motivates pragmatism. (shrink)

A moral-pragmatic argument for a proposition is an argument intended to establish that believing the proposition would be morally beneficial. Since such arguments do not adduce epistemic reasons, i.e., reasons that support the truth of a proposition, they can seem at best to be irrelevant epistemically. At worst, believing on the basis of such reasoning can seem to involve wishful thinking and intellectual dishonesty of a sort that that precludes such beliefs from being epistemically unjustified. Inspired by an argument from (...) William James’ classic, “The Will to Believe”, I argue that there is a way of making sense of moral-pragmatic arguments such that they are epistemically relevant. I develop and argue for a theory of epistemic justification that I dub the “moral encroachment theory” (emphasizing its connection to recent pragmatic encroachment views). According to the theory, moral considerations can raise or lower epistemic standards from where they would be in morally neutral settings. The moral encroachment theory, I contend, denotes a normative property that is at once distinctively epistemic and valuable. The theory also allows a legitimate role for moral-pragmatic reasoning under certain conditions. The upshot is that moral-pragmatic reasoning can be epistemically as well as morally appropriate.

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)

This paper develops a precise understanding of the thesis of moral encroachment, which states that the epistemic status of an opinion can depend on its moral features. In addition, I raise objections to existing accounts of moral encroachment. For instance, many accounts fail to give sufficient attention to moral encroachment on credences. Also, many accounts focus on moral features that fail to support standard analogies between pragmatic and moral encroachment. Throughout the paper, I discuss racial profiling as a case study, (...) arguing that moral encroachment can help us identify one respect in which racial profiling is epistemically problematic.

We argue, contrary to epistemological orthodoxy, that knowledge is not purely epistemic—that knowledge is not simply a matter of truth‐related factors (evidence, reliability, etc.). We do this by arguing for a pragmatic condition on knowledge, KA: if a subject knows that p, then she is rational to act as if p. KA, together with fallibilism, entails that knowledge is not purely epistemic. We support KA by appealing to the role of knowledge‐citations in defending and criticizing actions, and by giving a (...) principled argument for KA, based on the inference rule KB: if a subject knows that A is the best thing she can do, she is rational to do A. In the second half of the paper, we consider and reject the two most promising objections to our case for KA, one based on the Gricean notion of conversational implicature and the other based on a contextualist maneuver. (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. (shrink)

This paper is about the ‘threshold problem’ for knowledge, namely, how do we determine what fixes the level of justification required for knowledge in a non-arbitrary way? One popular strategy for solving this problem is impurism, which is the view that the required level of justification is partly fixed by one’s practical reasoning situation. However, this strategy has been the target of several recent objections. My goal is to propose a new version of impurism that solves the threshold problem without (...) succumbing to these criticisms. (shrink)

According to ‘orthodox’ epistemology, it has recently been said, whether or not a true belief amounts to knowledge depends exclusively on truth-related factors: for example, on whether the true belief was formed in a reliable way, or was supported by good evidence, and so on. Jason Stanley refers to this as the ‘intellectualist’ component of orthodox epistemology, and Jeremy Fantl and Matthew McGrath describe it as orthodox epistemology’s commitment to a ‘purely epistemic’ account of knowledge — that is, an account (...) of knowledge where only truth-related factors figure in whether or not a person knows. In the first part of this paper I try to clarify the intellectualist thesis and to distinguish what I take to be its two main strains. In the remainder of the paper I then take a more critical turn and argue that even if, as a matter of fact, traditional epistemology has endorsed intellectualism in both of its strains, this is a mistake on the part of the tradition. At least one way of understanding intellectualism should be rejected and its practicalist counterpart should be accepted instead. (shrink)

According to doxastic pragmatism, certain perceived practical factors, such as high stakes and urgency, have systematic effects on normal subjects’ outright beliefs. Upholders of doxastic pragmatism have so far endorsed a particular version of this view, which we may call threshold pragmatism. This view holds that the sensitivity of belief to the relevant practical factors is due to a corresponding sensitivity of the threshold on the degree of credence necessary for outright belief. According to an alternative but yet unrecognised version (...) of doxastic pragmatism, practical factors affect credence rather than the threshold on credence. Let’s call this alternative view credal pragmatism. In this paper, I argue that credal pragmatism is more plausible than threshold pragmatism. I show that the former view better accommodates a cluster of intuitive and empirical data. I conclude by considering the issue of whether our doxastic attitudes’ sensitivity to practical factors can be considered rational, and if yes, in what sense. (shrink)

Evidentialism is the view that facts about whether or not an agent is justified in having a particular belief are entirely determined by facts about the agent’s evidence; the agent’s practical needs and interests are irrelevant. I examine an array of arguments against evidentialism (by Jeremy Fantl, Matthew McGrath, David Owens, and others), and demonstrate how their force is affected when we take into account the relation between degrees of belief and outright belief. Once we are sensitive to one of (...) the factors that secure thresholds for outright believing (namely, outright believing that p in a given circumstance requires, at the minimum, that one’s degree of belief that p is high enough for one to be willing to act as if p in the circumstances), we see how pragmatic considerations can be relevant to facts about whether or not an agent is justified in believing that p—but largely as a consequence of the pragmatic constraints on outright believing.

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)

This chapter addresses concerns that pragmatic encroachers are committed to problematic knowledge variance. It first replies to Charity Anderson and John Hawthorne’s new putative problem cases, which purport to show that pragmatic encroachment is committed to problematic variations in knowledge depending on what choices are available to the potential knower. It argues that the new cases do not provide any new reasons to be concerned about the pragmatic encroacher’s commitment to knowledge-variance. The chapter further argues that concerns about knowledge-variance are (...) not limited to the pragmatic encroacher, but come up for traditional purist invariantism as well. (shrink)

This paper argues for two theses: that degrees of belief are context sensitive; that outright belief is belief to degree 1. The latter thesis is rejected quickly in most discussions of the relationship between credence and belief, but the former thesis undermines the usual reasons for doing so. Furthermore, identifying belief with credence 1 allows nice solutions to a number of problems for the most widely-held view of the relationship between credence and belief, the threshold view. I provide a sketch (...) of a formal framework on which both theses are true. This is a modified Bayesian framework; I argue that despite making credences context-sensitive, the framework lets Bayesians hold on to their signature explanatory successes. The sort of context-sensitivity claimed for credences here mirrors the sort of context-sensitivity I have elsewhere claimed for outright belief: one's credences depend, in part, on the space of alternative possibilities one takes seriously in a context. (shrink)

Recent proposals that frame norms of action in terms of knowledge have been challenged by Bayesian decision theorists. Bayesians object that knowledge-based norms conflict with the highly successful and established view that rational action is rooted in degrees of belief. I argue that the knowledge-based and Bayesian pictures are not as incompatible as these objectors have made out. Attending to the mechanisms of practical reasoning exposes space for both knowledge and degrees of belief to play their respective roles.
