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.

Many epistemologists call themselves ‘fallibilists’. But many philosophers of language hold that the meaning of epistemic usages of ‘possible’ ensures a close knowledge- possibility link : a subject’s utterance of ‘it’s possible that not-p’ is true only if the subject does not know that p. This seems to suggest that whatever the core insight behind fallibilism is, it can’t be that a subject could have knowledge which is, for them, possibly false. I argue that, on the contrary, subjects can have (...) such possibly false knowledge. My ultimate aim, then, is to vindicate a very robust form of fallibilism. Uniquely, however, the account I offer does this while also allowing that concessive knowledge attributions – sentences of the form “I know that p, but it’s possible that not-p” – are not only infelicitous but actually false whenever uttered. The account predicts this result without conceding KPL. I argue that my account has the resources to explain some related cases for which the KPL account yields the wrong predictions. Taken as a whole, the linguistic data not only do not support the proposal that subjects cannot have possibly false knowledge, but indeed positively favor the proposal that they can. (shrink)

This book takes purism about knowledge as the default position and defends it from the challenges of pragmatic encroachment. The book is divided into two parts, a negative and a positive one. The negative part critically examines existing purist strategies in response to pragmatic encroachment. The positive part provides a new theory of how practical factors can systematically influence our confidence and explores some implications of such influence.

I consider difficult data involving the interaction of attitudes and conditionals, specifically non-doxastic attitude expressions like 'regret'. I first show that felicitous attitude conditionals in "ignorance contexts", where the relevant person doesn't know the antecedent is true, give rise to a number of difficult problems given widely held assumptions in semantics. I then argue that, even so, we should expect these conditionals to be true and reasonable to utter in ignorance contexts, given certain other kinds of attitude construction that tend (...) to involve free relatives like `whatever'. I then use that observation to explain many of the more puzzling aspects of these conditionals, and to show that we should treat felicitous doxastic attitude conditionals differently from felicitous non-doxastic ones. I leave explaining felicitous doxastic attitude conditionals for future work, but offer constraints on a satisfying explanation of them. (shrink)

This paper draws a line of demarcation between fallibilism and infallibilism. Taking Cartesian Infallibilism as a guide, it advances a picture of infallibilism whereby infallible knowledge requires, among other conditions, luminosity of a truth-guaranteeing property. Some implications for contemporary theories of knowledge are explored.

In a recent paper in this journal Duncan Pritchard responds to an objection to the modal account of risk pressed by Ebert, Smith and Durbach ( 2020 ). In this paper, I expand upon the objection and argue that it still stands. I go on to consider a more general question raised by this exchange – whether risk is ‘objective’, or whether it is something that varies from one perspective to another.

This paper focuses on the relation between epistemic reasons and the subject’s epistemic perspective. It tackles the questions of whether epistemic reasons are dependent on the perspective of the subject they are reasons for, and if so, whether they are dependent on the actual or the potential perspective. It is argued that epistemic reasons are either independent or minimally dependent on the subject’s epistemic perspective. In particular, I provide three arguments supporting the conclusion that epistemic reasons are not dependent on (...) the subject’s actual perspective. Furthermore, I show that variants of these arguments apply against popular views holding that epistemic reasons depend on the subject’s potential perspective, such as the view that epistemic reasons are facts that one is in a position to know.

Hope, in its propositional construction "I hope that p," is compatible with a stated chance for the speaker that not-p. On fallibilist construals of knowledge, knowledge is compatible with a chance of being wrong, such that one can know that p even though there is an epistemic chance for one that not-p. But self-ascriptions of propositional hope that p seem to be incompatible, in some sense, with self-ascriptions of knowing whether p. Data from conjoining hope self-ascription with outright assertions, with (...) first- and third-person knowledge ascriptions, and with factive predicates suggest a problem: when combined with a plausible principle on the rationality of hope, they suggest that fallibilism is false. By contrast, the infallibilist about knowledge can straightforwardly explain why knowledge would be incompatible with hope, and can offer a simple and unified explanation of all the linguistic data introduced here. This suggests that fallibilists bear an explanatory burden which has been hitherto overlooked. (shrink)

In “How to Be an Infallibilist,” Julien Dutant (2016, 149) presents a simple and seemingly plausible argument that knowledge requires infallible belief—roughly, belief that could not be mistaken. As Dutant recognizes, infallibilism is almost universally dismissed, in large part because it seems to rule out any knowledge of the physical world. He seeks to show how we can be an Infallibilist without being a skeptic, based on the assumption that knowledge has a safety condition. I critically examine each line of (...) Dutant’s argument, showing that the argument is unsound on any plausible interpretation. I also question the idea that knowledge cannot be the conjunction of true belief and a nonfactive condition, that any belief about the physical world could not be false, and that any nonskeptical alternative to infallibilism would have to allow knowledge of chancy outcomes. I briefly suggest that a fallibilist account can be strict enough to satisfy the Infallibilist’s quest for certainty. (shrink)

In this paper, I provide an account of epistemic anxiety as an emotional response to epistemic risk: the risk of believing in error. The motivation for this account is threefold. First, it makes epistemic anxiety a species of anxiety, thus rendering psychologically respectable a notion that has heretofore been taken seriously only by epistemologists. Second, it illuminates the relationship between anxiety and risk. It is standard in psychology to conceive of anxiety as a response to risk, but psychologists – very (...) reasonably – have little to say about risk itself, as opposed to risk judgement. In this paper, I specify what risk must be like to be the kind of thing to which anxiety can be a response. Third, my account improves on extant accounts of epistemic anxiety in the literature. It is more fleshed out than Jennifer Nagel’s, which is largely agnostic about the nature of epistemic anxiety, focusing instead on what work it does in our epistemic lives. In offering an account of epistemic anxiety as an emotion, my account explains how it is able to do the epistemological work to which Nagel puts it. My account is also more plausible than Juliette Vazard’s, on which epistemic anxiety is an emotional response to potential threat to one’s practical interests. Vazard’s account cannot distinguish epistemic anxiety from anxiety in general, and also fails to capture all instances of what we want to call epistemic anxiety. My account does better on both counts. (shrink)

According to epistemic fallibilism, we cannot be certain of anything. According to the Christian tradition, faith comes with certainty. I develop this dilemma from recent accounts of fallibilism and various representatives of the Christian tradition. I then argue that on John Henry Newman's account of faith the dilemma is merely apparent. Finally, I develop Newman's account of the certainty that accompanies faith and is compatible with fallibilism.

I provide an objection to an argument targeting the claim that epistemic modality concerns what is possible or necessary given what is known. The argument centers around uses of epistemic modals that co-occur with adjuncts of the form 'according to X', those in which the content of some reported information is at issue. I argue that such contexts do not license us to reach the sort of conclusion that the argument aims to reach.
