In this paper, I identify the hard problem of access for epistemological disjunctivism (ED): given that perceptual experience E is opaque with respect to its own epistemic properties, subject S is not in a position to know epistemic proposition (i) (that E is factive with respect to empirical proposition p) just by having E and/or reflecting on E. This is the case even if (i) is true. I first motivate the hard problem of access (Section 2) and then reconstruct and analyze three of the ways in which EDists have argued for the internal accessibility of the factive character of perceptual experience. These arguments explain internal access in terms of the unity of perceptual and rational capacities (Section 3), favoring support (Section 4), and the outward-looking model of self-knowledge (Section 5). My conclusion (Section 6) is that none of these responses works. I then suggest how ED might be modified to succeed as an access internalist epistemology.

There are epistemic manipulators in the world. These people are actively attempting to sacrifice epistemic goods for personal gain. In doing so, manipulators have led many competent epistemic agents into believing contrarian theories that go against well-established knowledge. In this paper, I explore one mechanism by which manipulators get epistemic agents to believe contrarian theories. I do so by looking at a prominent empirical model of trustworthiness. This model identifies three major factors that epistemic agents look for when trying to determine who is trustworthy. These are (i) ability, (ii) benevolence, and (iii) moral integrity. I then show how manipulators can manufacture the illusion that they possess these factors. This leads epistemic agents to view manipulators as trustworthy sources of information. Additionally, I argue that fact-checking will be an ineffective – or even harmful – practice when correcting the beliefs of epistemic agents who have been tricked by this illusion of epistemic trustworthiness. I suggest that in such cases we should use an alternative correction, which I call trust undercutting.

In this paper, I argue that echo chambers pose a problem for moral progress because of their threat to moral reasoning. I argue for two theses about the epistemology of moral progress: (1) the practical utility thesis: moral reasoning plays an important role in improving moral judgments, and (2) the conflictive social reasoning thesis: the kind of moral reasoning that is important for moral progress involves social reasoning with disputants. Without some conflict, human beings will naturally reason in a biased and otherwise poor manner. Thus, good reasoning must be social so that reasoners who disagree can keep each other in check. These two theses explain why echo chambers are a problem for moral progress. I argue that echo chambers isolate individuals from reasoning with those they disagree with. This is because echo chambers act as a mechanism for discrediting those outside the chamber. If this is true, then the members of an echo chamber will only reason with those who agree with them. The result is that echo chamber members won't reason according to the conflictive social reasoning thesis. Reasoning will only reinforce their existing echoed beliefs rather than improve them.

This article is an exercise in the virtue epistemology of the internet, an area of applied virtue epistemology that investigates how online environments impact the development of intellectual virtues, and how intellectual virtues manifest within online environments. I examine online echo chambers and epistemic bubbles (Nguyen 2020, Episteme 17(2), 141–61), exploring the conceptual relationship between these online environments and the virtue of open-mindedness (Battaly 2018b, Episteme 15(3), 261–82). The article answers two key individual-level, virtue epistemic questions: (Q1) How does immersion in online echo chambers and epistemic bubbles affect the cultivation and preservation of open-mindedness, and (Q2) Is it always intellectually virtuous to exhibit open-mindedness in the context of online echo chambers and epistemic bubbles? In response to Q1, I contend that both online echo chambers and online epistemic bubbles threaten to undermine the cultivation and preservation of open-mindedness, albeit via different mechanisms and to different degrees. In response to Q2, I affirm that both a deficiency and excess of open-mindedness can be virtuous in these online environments, depending on the epistemic orientation of the digital user.

The claim that prejudice causes prejudiced beliefs is a familiar one. Call it the causal claim. In this paper, I turn to sexism and sexist beliefs to explore the causal claim within the context of current debates in the ethics of beliefs about moral encroachment on epistemic rationality. My goal is to consider and arbitrate between plausible ways of fleshing out the idea that the non-doxastic dimensions of sexism (including its motivational and affective components as well as its structural and institutional varieties) cause sexist beliefs in a normatively significant way – that is, in a way that can render those beliefs epistemically deficient. I suggest that, in conjunction with the assumption that sexist beliefs are epistemically irrational, each position in the ethics of belief debate lends itself to a different interpretation of the causal claim: purism about epistemic rationality supports a narrow interpretation, while revisionism supports a broad one. After developing each interpretation, I argue that – at the heart of the disagreement between them – is a different story about the normative significance of the fact that evidence about an unfortunate truth has a sexist provenance. Along the way, I consider what it means for evidence to be “stacked in favor” of sexist beliefs.

Risk is inherent to many, if not all, transformative decisions. The risk of regret, of turning into a person you presently consider to be morally objectionable, or of value change are all risks of choosing to transform. This aspect of transformative decision-making has thus far been ignored, but carries important consequences to those wishing to defend decision theory from the challenge posed by transformative decision-making. I contend that a problem lies in a common method used to cardinalise utilities – the von Neumann and Morgenstern (vNM) method – which measures an agent's utility function over sure outcomes. I argue that the risks involved in transformative experiences are constitutively valuable, and hence their value cannot be accurately measured by the vNM method. In Section 1, I outline what transformative experiences are and the problem they pose to decision theory. In Section 2, I outline Pettigrew's (2019, Choosing for Changing Selves) decision-theoretic response, and in Section 3, I present the case for thinking that risks can carry value. In Section 4, I argue for the claim that at least some transformative experiences involve constitutive risk. I argue that this causes a problem for decision-theoretic responses within the vNM framework in Section 5.

You have hands, but does it follow that there’s an external material world? Moore thought so. However, we argue that this is a mistake. We defend the Ecumenical View, on which ordinary object terms like “hands” are metaphysically ecumenical, akin to the way that terms like “table” are physically ecumenical: just as there are wooden, metal, or plastic tables, so too there can be material, virtual, or immaterial hands. Moore’s position, however, is metaphysically sectarian: the semantics of “hands” requires a materialist metaphysics. Moore’s proof fails not because it displays bad epistemology but because of its problematic commitment to sectarian metaphysics. We conclude with some explorative thoughts on how the Ecumenical View bears on common sense epistemology and a possible equivocation in our understanding of the premises of Moore’s argument.

Recent research has highlighted the character and importance of the study of agreement. This paper, paralleling work on the more familiar concept of deep disagreement, will provide a first articulation of the character and implications of deep agreements, that is, agreements so deep that disagreement cannot overcome them. To do so, I start by outlining the main features of deep disagreement. I then provide a brief characterization of agreement in general to ground the discussion of the unique characteristics of deep agreements and compare them to deep disagreements. After distinguishing the concept from other more familiar ones, I then point to a few of the major social and theoretical issues the existence of deep agreements poses before concluding with some remarks pointing to valuable areas for future research.

In this paper I offer a characterization of the intellectual virtue of social inquisitiveness, paying attention to its difference from the individual virtue of inquisitiveness. I defend that there is a significant distinction between individual and social epistemic virtues: individual epistemic virtues are attributed to individuals and assessed by the quality of their cognitive powers, while social epistemic virtues are attributed to epistemic communities and are assessed by the quality of the epistemic relations within the communities. I begin presenting Lani Watson's characterization of the (individual) practice of questioning and its related intellectual virtue, inquisitiveness. While she does not employ normative language, I show that her description can be constructed through four norms. Then, based on an account of epistemic communities, I defend that, while epistemic virtues attributable to individuals have norms regulating cognitive powers, epistemic virtues attributable to epistemic communities have norms regulating social epistemic interactions and shared epistemic responsibility. I then present a robust characterization of the epistemic virtue of social inquisitiveness through its social epistemic norms: DISTRIBUTION, ACCESSIBILITY, SOCIAL SINCERITY, SOCIAL CONTEXT, and FREQUENCY. I respond to two possible objections to my account and conclude by offering suggestions to broaden the scope of the epistemology of questioning.

We acquire from others many of our epistemic resources – individual items of propositional knowledge but also evidential standards, perceptual sensibilities, and the overarching perspectives that include beliefs, standards, and sensibilities together. Knowledge from testimony, which is one category of acquisition of epistemic resources from others, has been studied extensively by epistemologists. We can begin to explore the wider realm of epistemic sharing by varying the characteristic features of testimony. Eleven dimensions of variation provide some structure to this domain. The interactive complexity of the dimensions suggests a virtue epistemological approach to the evaluation of patterns of receptivity to the variety of sharings that we confront as knowers.

A proof ${\cal P}$ of a theorem T is transferable when it's possible for a typical expert to become convinced of T solely on the basis of their prior knowledge and the information contained in ${\cal P}$. Easwaran has argued that transferability is a constraint on acceptable proof. Meanwhile, a proof ${\cal P}$ is fixable when it's possible for other experts to correct any mistakes ${\cal P}$ contains without having to develop significant new mathematics. Habgood-Coote and Tanswell have observed that some acceptable proofs are both fixable and in need of fixing, in the sense that they contain non-trivial mistakes. The claim that acceptable proofs must be transferable seems quite plausible. The claim that some acceptable proofs need fixing seems plausible too. Unfortunately, these attractive suggestions stand in tension with one another. I argue that the transferability requirement is the problem. Acceptable proofs need to only satisfy a weaker requirement I call “corrigibility.” I explain why, despite appearances, the corrigibility standard is preferable to stricter alternatives.

Heather Battaly has argued that vice-epistemology has a Responsibility Problem. From analysing the ‘card-carrying feminist’ committing testimonial injustice due to implicit gender bias, Battaly argues that non-voluntarist vice-epistemologists are committed to either (1) counting some vices as blameworthy yet not reprehensible, or (2) holding agents equally responsible for cognitive defects as for implicit bias. This in turn implies that (2a) epistemic vices include certain cognitive defects or (2b) that implicit bias is excluded as epistemic vice. This paper aims to deflate the Responsibility Problem, by arguing that vice-epistemologists can embrace route (2b) without problematic implications. In applying Miranda Fricker’s ‘no-fault responsibility’ to the card-carrying feminist case, I defend the following three claims: First, Battaly’s analysis of the card-carrying feminist case is flawed, because it fails to acknowledge that the vice of testimonial injustice and implicit prejudice are conceptually distinct. Second, excluding implicit prejudice as a vice is actually compatible with Fricker’s theoretical commitments. Third, contrary to what much of the literature seems to assume, it isn’t that problematic to exclude (individual) implicit bias as a vice, or to assign equal responsibility for implicit prejudice as for cognitive defects like impaired vision.

Interpersonalist theories of testimony have the theoretical virtue of giving room to the characteristic interpersonal features of testimonial exchange among persons. Nonetheless, it has been argued that they are at a serious disadvantage when it comes to accounting for the way in which testimonial beliefs may be epistemically justified. In this paper, we defend the epistemological credentials of interpersonalism, emphasizing that it is inseparable from the acceptance of non-evidential epistemic reasons to believe, which demands proper conceptual elaborations on the notions of epistemic reasons and of epistemic justification. We offer a proper reading of epistemic reason, and we defend non-purism on justification as the adequate way to conceive the epistemic proposal of interpersonalism on testimony, realizing that only this combination is capable of apprehending certain cases in which there seems to be no way to rule out the idea that the assurance offered by the testifier offers an epistemic reason to believe that it is not evidential.

The relation between knowledge and action has been a lengthy debate in philosophy which traces back to Descartes and Locke. Purism holds that the practical factors related to action are fundamentally independent of the standard of knowledge, while pragmatic encroachment argues that practical considerations about action can impact judgments about knowledge. This traditional debate was put front and center recently by discussions on some knowledge attribution cases and relevant empirical studies. This paper reports three empirical studies based on three pairs of classic knowledge attribution cases on Chinese participants. The results indicate that folk's understanding of knowledge is more compatible with purism and suggest a conversational implicature account of the connection between judgments about knowledge and action.

Contra both phenomenalists and anti-phenomenalists, I defend the following thesis in this paper: the epistemic power of perceptual experience is grounded in its presentational property that is (i) uniquely possessed by the experience in the good case and (ii) essentially a phenomenal property. In §2, I set the ground for my argument by elaborating on the phenomenalist account of presentational phenomenology. In §3, I argue (against phenomenalism) for the first part of the phenomenal presentation thesis: (i) perceptual experience’s epistemic power is grounded in instances of a presentational property possessed by perceptual experience in the good, but not in the bad case. In §4, I argue (against anti-phenomenalists) for the second part of the phenomenal presentation thesis: (ii) presentational property is essentially a phenomenal property. In §5, I address some potential objections to the phenomenal presentation thesis. §6 concludes.

Are the members of echo chambers blameworthy for their beliefs? If we follow Sarah Stroud's account of friendship, we end up with the following conclusion: if echo chambers involve friendship, then the individuals have strong reasons not to live up to epistemic demands or ideals when the friendships are formed in the echo chambers they are members of. This result stands in striking contrast with the received view, according to which the members of echo chambers are blameworthy for their epistemic vices and faulty beliefs. The received view uses individual epistemic vices to propose individualistic solutions for the problem of echo chambers. I argue that this is misleading, simply because the members of echo chambers are not blameworthy due to the friendships cultivated in the echo chambers.

After offering a definition of “conspiracy theory” and highlighting some interesting interconnections between conspiracy theories and religious worldviews, we turn to epistemologically relevant analogies. Proponents of conspiracy theories and religions have often been accused of the same biases and epistemic vices, e.g., gullibility, hypersensitive proneness to personal explanations, or overemphasis on holistic thinking. So-called Generalism is best understood as the thesis that conspiracy theories are guilty until proven innocent because they share certain “bunkum-making properties.” However, we argue for the particularist position, i.e. the position that a general epistemic presumption against conspiracy theories is not tenable. Building a negative valence into the very notion of conspiracy theory is not convincing either. Given the analogies, our analysis supports similar verdicts with respect to religious worldviews: Like conspiracy theories, they should be evaluated on a case-by-case basis rather than being dismissed simply for being religious. Finally, we reject Bezazel’s view that both conspiracy theories and religious worldviews constitute a-rational frames or “bliks” that, besides other things, ground what counts as an explanation. Such a proposal squares badly with epistemic misgivings about particularly preposterous examples of conspiracy theories and religious worldviews.

Education as a thick epistemic concept (ETEC) is a thick epistemology project that highlights the role of education in both epistemic virtues acquisition and motivation. In this article, I argue that ETEC is not satisfactory because it relies on a version of virtue responsibilism (VR) that is also not plausible, in so far as it relies on the premise that both the motivation and the action-guidedness of epistemic and moral virtues are unified. By rejecting this unification premise, I show that an epistemically virtuous person is not necessarily a morally virtuous/caring person either. It might happen to be the case that an epistemically virtuous person is also a morally virtuous person. However, there is no necessary connection between the epistemic and moral virtues as VR and ETEC claim since there can be a sharp gap between their motivation and their action-guidedness. I also argue that there are bad forms of education that can further sharpen the gap between epistemic and moral virtues, further undermining ETEC. Thus, when it comes to education, a thick epistemology project should consider how different forms of education can sharpen the gap in the motivation and the action-guidedness of different types of virtues developed by learners.

According to one influential tradition, to assert that p is to express a belief that p. Yet how do assertions provide strong evidence for belief? Philosophers have recently drawn on evolutionary biology to help explain the stability of assertive communication. Mitchell Green suggests that assertions are akin to biological handicaps. Peter Graham argues against the handicap view and instead claims that the norms of assertion are deterrents. Contra Graham, I argue that both mechanisms may play a role in assertive communication, although assertions as deterrents will often fail to provide strong evidence for belief.
