This book concerns the foundations of epistemic modality and hyperintensionality and their applications to the philosophy of mathematics. I examine the nature of epistemic modality, when the modal operator is interpreted as concerning both apriority and conceivability, as well as states of knowledge and belief. The book demonstrates how epistemic modality and hyperintensionality relate to the computational theory of mind; metaphysical modality and hyperintensionality; the types of mathematical modality and hyperintensionality; to the epistemic status of large (...) cardinal axioms, undecidable propositions, and abstraction principles in the philosophy of mathematics; to the modal and hyperintensional profiles of the logic of rational intuition; and to the types of intention, when the latter is interpreted as a hyperintensional mental state. Chapter 2 argues for a novel type of expressivism based on the duality between the categories of coalgebras and algebras, and argues that the duality permits of the reconciliation between modal cognitivism and modal expressivism. I also develop a novel topic-sensitive truthmaker semantics for dynamic epistemic logic, and develop a novel dynamic epistemic two-dimensional hyperintensional semantics. Chapter 3 provides an abstraction principle for epistemic (hyper-)intensions. Chapter 4 advances a topic-sensitive two-dimensional truthmaker semantics, and provides three novel interpretations of the framework along with the epistemic and metasemantic. Chapter 5 applies the fixed points of the modal μ-calculus in order to account for the iteration of epistemic states in a single agent, by contrast to availing of modal axiom 4 (i.e. the KK principle). The fixed point operators in the modal μ-calculus are rendered hyperintensional, which yields the first hyperintensional construal of the modal μ-calculus in the literature and the first application of the calculus to the iteration of epistemic states in a single agent instead of the common knowledge of a group of agents. Chapter 6 advances a solution to the Julius Caesar problem based on Fine's `criterial' identity conditions which incorporate conditions on essentiality and grounding. Chapter 7 provides a ground-theoretic regimentation of the proposals in the metaphysics of consciousness and examines its bearing on the two-dimensional conceivability argument against physicalism. The topic-sensitive epistemic two-dimensional truthmaker semantics developed in chapters 2 and 4 are availed of in order for epistemic states to be a guide to metaphysical states in the hyperintensional setting. Chapters 8-12 provide cases demonstrating how the two-dimensional hyperintensions of hyperintensional, i.e. topic-sensitive epistemic two-dimensional truthmaker, semantics, solve the access problem in the epistemology of mathematics. Chapter 8 examines the interaction between my hyperintensional semantics and the axioms of epistemic set theory, large cardinal axioms, the Epistemic Church-Turing Thesis, the modal axioms governing the modal profile of Ω-logic, Orey sentences such as the Generalized Continuum Hypothesis, and absolute decidability. These results yield inter alia the first hyperintensional Epistemic Church-Turing Thesis and hyperintensional epistemic set theories in the literature. Chapter 9 examines the modal and hyperintensional commitments of abstractionism, in particular necessitism, and epistemic hyperintensionality, epistemic utility theory, and the epistemology of abstraction. I countenance a hyperintensional semantics for novel epistemic abstractionist modalities. I suggest, too, that observational type theory can be applied to first-order abstraction principles in order to make first-order abstraction principles recursively enumerable, i.e. Turing machine computable, and that the truth of the first-order abstraction principle for hyperintensions is grounded in its being possibly recursively enumerable and the machine being physically implementable. Chapter 10 examines the philosophical significance of hyperintensional Ω-logic in set theory and discusses the hyperintensionality of metamathematics. Chapter 11 provides a modal logic for rational intuition and provides a hyperintensional semantics. Chapter 12 avails of modal coalgebras to interpret the defining properties of indefinite extensibility, and avails of hyperintensional epistemic two-dimensional semantics in order to account for the interaction between the interpretational and objective modalities and truthmakers thereof. This yields the first hyperintensional category theory in the literature. I invent a new mathematical trick in which first order structures are treated as categories, and Vopenka's principle can be satisfied because of the elementary embeddings between the categories and generate Vopenka cardinals while bypassing the category of Set in category theory. Chapter 13 examines modal responses to the alethic paradoxes. Chapter 14 examines, finally, the modal and hyperintensional semantics for the different types of intention and the relation of the latter to evidential decision theory. (shrink)

This essay provides a novel account of iterated epistemic states. The essay argues that states of epistemic determinacy might be secured by countenancing iterated epistemic states on the model of fixed points in the modal $\mu$-calculus. Despite the epistemic indeterminacy witnessed by the invalidation of modal axiom 4 in the sorites paradox -- i.e. the KK principle: $\square$$\phi$ $\rightarrow$ $\square$$\square$$\phi$ -- a hyperintensional epistemic $\mu$-automaton permits fixed points to entrain a principled means by which (...) to iterate epistemic states and account thereby for necessary conditions on self-knowledge. The hyperintensional epistemic $\mu$-calculus is applied to the iteration of the epistemic states of a single agent instead of the common knowledge of a group of agents, and is thus a novel contribution to the literature.

A proof-theoretical treatment of collectively accepted group beliefs is presented through a multi-agent sequent system for an axiomatization of the logic of acceptance. The system is based on a labelled sequent calculus for propositional multi-agent epistemic logic with labels that correspond to possible worlds and a notation for internalized accessibility relations between worlds. The system is contraction- and cut-free. Extensions of the basic system are considered, in particular with rules that allow the possibility of operative members or legislators. (...) Completeness with respect to the underlying Kripke semantics follows from a general direct and uniform argument for labelled sequent calculi extended with mathematical rules for frame properties. As an example of the use of the calculus we present an analysis of the discursive dilemma. (shrink)

The ‘epistemic calculus of groups’ posits functions to group-generated knowledge. In this article, those same epistemic group functions are now re-evaluated as means by which group members may tackle two contemporary and increasing challenges, or even obstructions, to knowledge. These obstructions, namely the liminality, the increasingly transitional nature of both ‘common sense’ and ‘common word meanings,’ occur, as our mass and social media practices change. Can groups still remain as ‘epistemic communities’ and regenerate common (...) sense or common word meanings? As a response to media developments and to counterarguments by the analytic social epistemologists, I reconceptualize the functions of the ´epistemic calculus of groups´ as skills, and present a synthetic approach toward thinking in small groups to enable the regeneration of common meanings. As a basis in the analysis of the notions of common sense and common word meanings, I use the theory of psychologic: a theory built on formal logic. F... (shrink)

I connect two increasingly popular ideas in social epistemology—group knowledge and epistemic extension—both departures from mainstream epistemological tradition. In doing so, I generate a framework for conceptualizing and organizing contemporary epistemology along several core axes. This, in turn, allows me to delineate a largely unexplored frontier in group epistemology. The bulk of extant work in group epistemology can be dubbed intra-group epistemology: the study of epistemically salient happenings within groups. I delineate and attempt to motivate what I dub (...) inter-group epistemology: the study of epistemically salient happenings between groups and other subjects and entities. (shrink)

Epistemic paternalism occurs when a decision is made for an agent which helps them arrive at the truth, though they didn’t consent to that decision (and sometimes weren’t even aware of it). Common defenses of epistemic paternalism claim that it can help promote positive veritistic results. In other words, epistemic paternalism is often good for inquiry. I argue that there is often a better alternative available to epistemic paternalism in the form of what I call Open (...) Group Inquiry. I then examine how Open Group Inquiry can be applied to cases of religious inquiry, while noting that epistemic paternalism is impermissible in cases of general religious inquiry. I argue that in the case of religious inquiry, there are serious questions about what constitutes evidence along with how to evaluate it. Rather than posing a particular worry for Open Group Inquiry, I suggest these questions pose a problem for religious inquiry in general. I conclude that while it very much matters how concepts like religious knowledge, religious faith, scepticism, etc., are defined, these considerations may well pave the way for a novel argument for religious scepticism.

Recently, there has been growing concern that increased partisanship in news sources, as well as new ways in which people acquire information, has led to a proliferation of epistemic bubbles and echo chambers: in the former, one tends to acquire information from a limited range of sources, ones that generally support the kinds of beliefs that one already has, while the latter function in the same way, but possess the additional characteristic that certain beliefs are actively reinforced. Here I (...) argue, first, that we should conceive of epistemic bubbles and echo chambers as types of epistemically pernicious groups, and second, that while analyses of such groups have typically focused on relationships between individual members, at least part of what such groups epistemically pernicious pertains to the way that members rely on the groups themselves as sources of information. I argue that member reliance on groups results in groups being attributed a degree of credibility that outruns their warrant, a process I call groupstrapping. I argue that by recognizing the groupstrapping as an illicit method of forming and updating beliefs we can make progress on some of the open questions concerning epistemically pernicious groups.

If individual knowledge and justification can be vanquished by epistemic defeaters, then the same should go for group knowledge. Lackey (2014) has recently argued that one especially strong conception of group knowledge defended by Bird (2010) is incapable of preserving how it is that (group) knowledge is ever subject to ordinary mechanisms of epistemic defeat. Lackey takes it that her objections do not also apply to a more moderate articulation of group knowledge--one that is embraced widely in collective (...) epistemology--and which she does not challenge. This paper argues that given certain background premises that are embraced by orthodox thinking in collectivist epistemology, the more moderate account of group knowledge cannot make sense of either psychological or normative epistemic defeaters. I conclude by offering some suggestions for how the more moderate proposal might avoid this result. (shrink)

When an agent suffers in their capacity as a knower, they are a victim of epistemic injustice. Varieties of epistemic injustices have been theorised. A salient feature across these theories is that perpetrators and victims of epistemic injustice belong to different social groups. In this paper, I argue for a form of epistemic injustice that could occur between members of the same social group. This is a form of epistemic injustice where the knower is (...) first a victim of historical and continuing oppression. Secondly, they internalise and appreciate the systems that harm them as a knower. This is possible because the victim subscribes to perniciously formed epistemic systems. This form of epistemic injustice is a valuable explanatory tool for non-standard and obscure instances of epistemic injustice where the victim a) accepts and appreciates the injustice they experience and b) is even the seeming perpetrator of the injustice against themselves.

This book takes seriously the idea that at least some groups, such as corporations and governments, are genuine agents with mental states on which they act. For instance, in morally assessing a government’s response to the coronavirus pandemic, we are interested in what the government knew at various points as the pandemic developed. And in predicting the outcome of the current war in Ukraine, we might ask what Russia believes about the West’s determination to defend Ukraine. The book examines (...) a range of phenomena central to the epistemic and moral assessment of groups: group evidence, group belief, the basis of group belief, group justified belief, group knowledge, group motivation, and group blameless ignorance. Overall, the book defends a ‘non-summative’ functionalist view of groups. On a non-summative account of group phenomena, it is neither necessary nor sufficient for a group to have a property α that some/most/all of its members have that same property. By contrast, on a summative account it is necessary and sufficient for a group to have a property α that some/most/all of its members have that same property. Across the book I provide new arguments for non-summativism and new accounts of key group phenomena many of which have been relatively neglected in existing literature. While I provide independent arguments for a non-summative view of each phenomenon discussed, the conclusions of the chapters are mutually reinforcing. For adopting a non-summative account of one group phenomenon motivates adopting a non-summative account of others. (shrink)

In interdisciplinary research scientists have to share and integrate knowledge between people and across disciplinary boundaries. An important issue for philosophy of science is to understand how scientists who work in these kinds of environments exchange knowledge and develop new concepts and theories across diverging fields. There is a substantial literature within social epistemology that discusses the social aspects of scientific knowledge, but so far few attempts have been made to apply these resources to the analysis of interdisciplinary science. Further, (...) much of the existing work either ignores the issue of differences in background knowledge, or it focuses explicitly on conflicting background knowledge. In this paper we provide an analysis of the interplay between epistemic dependence between individual experts with different areas of expertise. We analyze the cooperative activity they engage in when participating in interdisciplinary research in a group, and we compare our findings with those of other studies in interdisciplinary research.

In this paper, I work towards a conceptualization of a new form of epistemic injustice – one that occurs within groups, as opposed to across groups – which I call ‘intra-group epistemic injustice’. Specifically, I focus on a case that occurs within the Jewish community, regarding what I and others see as the silencing of anti-Zionist Jews by Zionist Jews, via a conflation of Jewish identity with Zionism. Anti-Zionist Jews are accused by Zionist Jews of being (...) ‘self-hating Jews’ or perhaps not even Jews at all, and as such, the former’s contributions to discussions of what it means to be Jewish are preemptively disregarded by the latter. Consequently, the harm of this epistemic injustice is that it effectively issues a denial of one’s identity as a Jew, which may amount to a nearly complete denial of one’s self. (shrink)

Modern epistemic questions have largely been focused around the individual and her ability to acquire knowledge autonomously. More recently epistemologists have begun to look more broadly in providing accounts of knowledge by considering its social context, where the individual depends on others for true beliefs. Hardwig explains the effect of this shift starkly, arguing that to reject epistemic dependency is to deny certain true beliefs widely held throughout society and, more specifically, it is to deny that science and (...) scholarship can provide true belief. Alternatively, Hardwig argues that beliefs could be granted to communities or groups but denied to individuals. This paper approaches these broad assertions using a group agency model from List and Pettit. Through a discussion of the ‘epistemic desideratum’ of group agents, I conclude that List and Pettit give us reason to accept some of Hardwig's concerns, but that attributing beliefs to groups does not require us to deny them to individuals, rather an individual can use a group agent as a source of epistemic dependence.Send article to KindleTo send this article to your Kindle, first ensure no-reply@cambridge.org 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.

Sometimes we are interested in how groups are doing epistemically in aggregate. For instance, we may want to know the epistemic impact of a change in school curriculum or the epistemic impact of abolishing peer review in the sciences. Being able to say something about how groups are doing epistemically is especially important if one is interested in pursuing a consequentialist approach to social epistemology of the sort championed by Goldman. According to this approach we evaluate (...) social practices and institutions from an epistemic perspective based on how well they promote the aggregate level of epistemic value across a community. The aim of this paper is to investigate this concept of group epistemic value and defend a particular way of measuring it. (shrink)

In this paper, we investigate the effect described in the literature as the Group Knobe Effect, which is an asymmetry in ascription of intentionality of negative and positive side-effects of an action performed by a group agent. We successfully replicate two studies originally conducted by Michael and Szigeti, who observed this effect and provide empirical evidence of the existence of two related effects—Group Epistemic and Doxastic Knobe Effects—which show analogous asymmetry with respect to knowledge and belief ascriptions. We explain (...) how the existence of the Group Knobe Effect and its epistemic and doxastic counterparts affects the philosophical debate on collective agency and intentionality and supports the intuitiveness of realism about collective agency among laypeople. We also critically assess the reasoning presented by Michael and Szigeti in favor of the realist-collectivist interpretation of their results. We argue that a thorough analysis of both their data and our new findings shows a rather wide range of differing intuitions among laypeople regarding the status of groups as agents. These results show that while some laypeople may have realist-collectivist intuitions, the contrary realist-distrubutivist intuitions are also widespread and the claim that the majority of laypeople hold collectivist intuitions regarding group agency is unjustified.

Johann Gottlieb Fichte argues that one semantic presupposition of claims about our entitlements is the idea that others are capable of autonomy. Individuals cannot demand anything from others, even submission, unless they also presuppose—although perhaps without acknowledging this to themselves—that others are free agents. Thus, the autonomy of others is a pre-condition of our exercise of autonomy. Why do individuals and groups often try to justify their own entitlement to rights at the expense of the freedom of others, thereby (...) simultaneously assuming and denying their freedom? This paper investigates what constitution of group agency gives individual members of the group the best chance to develop and sustain a moral character consistent with the ideal of equal autonomy. I argue that liberalism fosters the sort of group agency that improves individuals’ chances to acquire epistemically reliable beliefs about the moral status of others. I apply my findings to the discussion of court decisions in Gaines, Brown, and the race nuisance cases. (shrink)

In this paper, I present an account of group competence that is explicitly framed for cases of epistemic performances. According to it, we must consider group epistemic competence as the group agents’ capacity to produce knowledge, and not the result of the summation of its individual members’ competences to produce knowledge. Additionally, I contend that group competence must be understood in terms of group normative status. To introduce my view, I present Jesper Kallestrup’s denial that group competence involves (...) anything over and beyond the aggregation of individual competences. I have divided my response into two parts. First, I compare two conceptions of competence from Ernest Sosa’s reliabilist virtue epistemology, Thinking about oneself: The place and value of reflection in philosophy and psychology, Springer, 2019) and David Löwenstein’s account of know-how. Second, I take the results from this comparison and apply them to the issue of group know-how, by the hand of Orestis Palermos and Deborah Tollefsen’s twofold approach to the topic Socially extended epistemology, Oxford University Press, 2018). Finally, I return to Kallestrup’s denial to make my point in favour of the conception of genuine group competence as the group normative status to achieve success. (shrink)

Humans are prone to producing morally suboptimal and even disastrous outcomes out of ignorance. Ignorance is generally thought to excuse agents from wrongdoing, but little attention has been paid to group-based ignorance as the reason for some of our collective failings. I distinguish between different types of first-order and higher order group-based ignorance and examine how these can variously lead to problematic inaction. I will make two suggestions regarding our epistemic obligations vis-a-vis collective (in)action problems: (1) that our (...) class='Hi'>epistemic obligations concern not just our own knowledge and beliefs but those of others, too and (2) that our epistemic obligations can be held collectively where the epistemic tasks cannot be performed by individuals acting in isolation, for example, when we are required to produce joint epistemic goods.

This paper examines the role of evidential considerations in relation to pragmatic concerns in statements of group belief, focusing on scientific collaborations that are constituted in part by the aim of evaluating the evidence for scientific claims (evidential collaborations). Drawing upon a case study in high energy particle physics, I seek to show how pragmatic factors that enter into the decision to issue a group statement contribute positively to the epistemic functioning of such groups, contrary to the implications (...) of much of the existing discussion of group belief. I conclude by suggesting that applying social epistemological considerations to scientific collaborations could be practically beneficial, but only if an appropriately broad range of epistemic values is considered.

In the present article, we introduce a multi-type display calculus for dynamic epistemic logic, which we refer to as Dynamic Calculus. The display approach is suitable to modularly chart the space of dynamic epistemic logics on weaker-than-classical propositional base. The presence of types endows the language of the Dynamic Calculus with additional expressivity, allows for a smooth proof-theoretic treatment, and paves the way towards a general methodology for the design of proof systems for the generality (...) of dynamic logics, and certainly beyond dynamic epistemic logic. We prove that the Dynamic Calculus adequately captures Baltag–Moss–Solecki's dynamic epistemic logic, and enjoys Belnap-style cut elimination. (shrink)

The way in which the theory of “group selection” was treated as a heresy in evolutionary biology during the latter part of the twentieth century is considered as itself being an emergent group phenomenon, and some possible reasons why this particular theory had to be repudiated by the dominant group are explored. Then the process of “heresy-hammering” in general is examined as a behavior that can block important feedback, allowing the group to engage in a form of collective selfdeception, and (...) is therefore judged to be epistemically irresponsible and potentially maladaptive in terms of the group’s long-term survival. Some possible methods of foiling this process—which seems to operate largely below the level of full conscious awareness—are proposed. (shrink)

According to distributed virtue reliabilism (Palermos, 2020b), epistemic collaborations—such as Transactive Memory Systems and Scientific Research Teams—can be held epistemically responsible at the collective level. This raises the question of whether participants of epistemic collaborations are exempt from being held individually responsible. In response, this paper explores two possible ways in which attributions of individual responsibility may still be appropriate within epistemic collaborations: (I) Individuals can be held epistemically responsible for their individual shortcomings, but no amount of (...) individual epistemic responsibility can replace collective epistemic responsibility. (II) Even if it is denied that participants of epistemic collaborations can be held epistemically responsible at the individual level, they may be held structurally, perhaps morally, and even legally responsible at the individual level for breaking joint commitments necessary for the effective coordination of the epistemic collaboration.

Do epistemic intuitions tell us anything about knowledge? Stich has argued that we respond to cases according to our contingent cultural programming, and not in a manner that tends to reveal anything significant about knowledge itself. I’ve argued that a cross-culturally universal capacity for mindreading produces the intuitive sense that the subject of a case has or lacks knowledge. This paper responds to Stich’s charge that mindreading is cross-culturally varied in a way that will strip epistemic intuitions of (...) their evidential value. I argue that existing work on cross-cultural variation in mindreading favors my position over Stich’s. (shrink)

Intuitions play an important role in contemporary epistemology. Over the last decade, however, experimental philosophers have published a number of studies suggesting that epistemic intuitions may vary in ways that challenge the widespread reliance on intuitions in epistemology. In a recent paper, Jennifer Nagel offers a pair of arguments aimed at showing that epistemic intuitions do not, in fact, vary in problematic ways. One of these arguments relies on a number of claims defended by appeal to the psychological (...) literature on intuitive judgment and on mental state attribution (also known as “theory of mind”, “mindreading” and “folk psychology”). I call this the "theoretical argument". The other argument relies on recent experimental work carried out by Nagel and her collaborators. It is my contention that in setting out her theoretical argument, Nagel offers an account of the relevant scientific literature that is, in crucial respects, flawed and misleading. My main goal in this paper is to rectify these errors and to make it clear that, once this is done, Nagel’s theoretical argument collapses. Since Nagel’s experimental work has not yet been published, and available details are very sketchy, I do not discuss this work in detail. However, in the final section of the paper I offer some critical observations about Nagel’s strategy for dealing with empirical data that does not support her view – both other people’s and her own.

​I use network models to simulate social learning situations in which the dominant group ignores or devalues testimony from the marginalized group. I find that the marginalized group ends up with several epistemic advantages due to testimonial ignoration and devaluation. The results provide one possible explanation for a key claim of standpoint epistemology, the inversion thesis, by casting it as a consequence of another key claim of the theory, the unidirectional failure of testimonial reciprocity. Moreover, the results complicate the (...) understanding and application of previously discovered network epistemology effects, notably the Zollman effect (Zollman 2007, 2010). (shrink)

This essay follows Fiala’s hopefulness and his analysis of the coordination of a trio of actors needed for tyranny to succeed with a suggestion that preventing tyranny requires also a collective understanding, and education, of the coordination of citizens needed to create and sustain a democracy. Just as no one person can succeed at becoming a tyrant on their own, no one can achieve democracy on their own. Democracy is group work, conducted through epistemic interdependence, trust, and political friendships.

This paper aims to explore disciplinary variation in valuation practices by comparing the way research groups accumulate credibility across four epistemic cultures. Our analysis is based on case studies of four high-performing research groups representing very different epistemic cultures in humanities, social sciences, geosciences and mathematics. In each case we interviewed about ten researchers, analyzed relevant documents and observed a couple of meetings. In all four cases we found a cyclical process of accumulating credibility. At the (...) same time, we found significant differences in the manifestation of the six main resources that are part of the cycle, the mechanisms of conversion between these resources, the overall structure and the average speed of the credibility cycle. The different ways in which the groups use data and produce arguments affect the whole cycle of accumulating credibility. In some cultures, journal publications are the main source of recognition, but in others one can earn significant amounts of recognition for conference contributions or service to the academic community. Moreover, the collaboration practices in the respective fields strongly influence the connection between arguments and publications. In cultures where teams of researchers collaboratively produce arguments, it is more strongly embedded in the process of writing publications. We conclude that the credibility cycle can only be used as an analytical tool to explain the behavior of researchers or research groups when taking differences across epistemic cultures into account.

The aim of this paper is to present a strongly complete first order functional predicate calculus generalized to models containing not only ordinary classical total functions but also arbitrary partial functions. The completeness proof follows Henkin’s approach, but instead of using maximally consistent sets, we define saturated deductively closed consistent sets . This provides not only a completeness theorem but a representation theorem: any SDCCS defines a canonical model which determine a unique partial value for every predicate symbol and (...) any function symbol. Any SDCCS can thus be interpreted as an epistemic state. (shrink)

A prominent question in social epistemology concerns the epistemic profile of groups. While inflationists and deflationists agree that groups are fit to constitute knowers, they disagree about whether group knowledge is reducible to knowledge of their individual members. This paper develops and defends a weak inflationist view according to which some, but not all, group knowledge is over and above any knowledge of their members. This view sits between the deflationist view that all group knowledge is reducible (...) to individual knowledge, and the strong inflationist view that some such knowledge even fails to supervene on features of individuals. Thus, some group knowledge is irreducible, but all such knowledge is anchored in, and so doesn't float freely from, individual features. (shrink)

The contemporary theory of epistemic democracy often draws on the Condorcet Jury Theorem to formally justify the ‘wisdom of crowds’. But this theorem is inapplicable in its current form, since one of its premises – voter independence – is notoriously violated. This premise carries responsibility for the theorem's misleading conclusion that ‘large crowds are infallible’. We prove a more useful jury theorem: under defensible premises, ‘large crowds are fallible but better than small groups’. This theorem rehabilitates the importance (...) of deliberation and education, which appear inessential in the classical jury framework. Our theorem is related to Ladha's (1993) seminal jury theorem for interchangeable (‘indistinguishable’) voters based on de Finetti's Theorem. We also prove a more general and simpler such jury theorem. (shrink)

It is widely acknowledged that individual moral obligations and responsibility entail shared (or joint) moral obligations and responsibility. However, whether individual epistemic obligations and responsibility entail shared epistemic obligations and responsibility is rarely discussed. Instead, most discussions of doxastic responsibility focus on individuals considered in isolation. In contrast to this standard approach, I maintain that focusing exclusively on individuals in isolation leads to a profoundly incomplete picture of what we're epistemically obligated to do and when we deserve (...) class='Hi'>epistemic blame. First, I argue that we have epistemic obligations to perform actions of the sort that can be performed in conjunction with other people, and that consequently, we are often jointly blameworthy when we violate shared epistemic obligations. Second, I argue that shared responsibility is especially important to doxastic responsibility thanks to the fact that we don't have the same kind of direct control over our beliefs that we have over our actions. In particular, I argue that there are many cases in which a particular individual who holds some problematic belief only deserves epistemic blame in virtue of belonging to a group all the members of which are jointly blameworthy for violating some shared epistemic obligation.

I begin with some familiar conceptions of epistemic relativism. One kind of epistemic relativism is descriptive pluralism. This is the simple, non-normative thesis that many different communities, cultures, social networks, etc. endorse different epistemic systems (E-systems), i.e., different sets of norms, standards, or principles for forming beliefs and other doxastic states. Communities try to guide or regulate their members’ credence-forming habits in a variety of different, i.e., incompatible, ways. Although there may be considerable overlap across cultures in (...) certain types of epistemic norms (e.g., norms for perceptual belief), there are sharp differences across groups in other types of epistemic norms.

Various social epistemologists employ what seem to be rather distinct notions of group rationality. In this essay, I offer an account of group rationality that is able to unify the dominant notions present in the literature under a single framework. I argue that if we employ a teleological account of epistemic rationality, and then allow that there are many different epistemic goals that are worth pursuing for various groups and individuals, we can then see how those seemingly (...) divergent understandings of group rationality are all intimately related. I close by showing how the view has the additional benefit of allowing us to generate practical, normative suggestions for groups in the real world. (shrink)

The practice of Emergency Management in Michigan raises anew the question of whose knowledge matters to whom and for what reasons, against the background of what projects, challenges, and systemic imperatives. In this paper, I offer a historical overview of state intervention laws across the United States, focusing specifically on Michigan’s Emergency Manager laws. I draw on recent analyses of these laws to develop an account of a phenomenon that I call epistemic redlining, which, I suggest, is a form (...) of group-based credibility discounting not readily countenanced by existing, ‘culprit-based’ accounts of epistemic injustice. I argue that epistemic redlining plays a crucial role in ongoing projects of racialized subordination and dispossession in Michigan, and that such discounting tends to have structural causes that can be difficult to identify and uproot. Contrary to the general thrust of recent work on the topic, I argue that epistemic redlining ought to be understood as a form of epistemic injustice. (shrink)

Throughout scientific history, there have been cases of mainstream science dismissing novel ideas of less prominent researchers. Nowadays, many researchers with different social and academic backgrounds, origins and gender identities work together on topics of crucial importance. Still, it is questionable whether the privileged groups consider the views of underprivileged colleagues with sufficient attention. To profit from the diversity of thoughts, the scientific community first has to be open to minority viewpoints and epistemically include them in mainstream research. Moreover, (...) the idea of inclusive science poses stronger requirements than the paradigm of open science. We argue that the concept of integration of different opinions is insufficient because the process of integration assumes adjusting oneself to the majority view and fitting into the dominant paradigm while contributing only with smaller amendments. Epistemic inclusion, on the other hand, means dynamically changing the research paradigm during the interaction with diverse methods and hypotheses. The process of inclusion preserves marginalized views and increases epistemic justice. (shrink)

Epistemic injustices are wrongs done concerning a person’s capacity as a knower. These actions are usually caused by prejudice and involve the distortion and neglect of certain marginalized groups’ opinions and ways of knowing. A type of epistemic injustice is hermeneutical injustice, which occurs when a person cannot effectively communicate or understand their experience, since it is excluded in scholarship, journalism, and discourse within their community. Indigenous Peoples (IPs) are especially vulnerable to hermeneutical injustice because their way (...) of life is unfamiliar or inaccessible to others. This leads to the exclusion of their ideas from public discourse, especially those important for human and societal development. This phenomenon is particularly evident in instances related to IP education. José Medina claims that there are cases of hermeneutical injustice which hinders the ability of people to share and make meaning, or simply, hermeneutical death. Ben Kotzee, on the other hand, identifies the specific educational dimension of epistemic injustice. Using both of these frameworks and citing the results of local studies on indigenous education as illustrative points, we attempt to show instances and scope of hermeneutical injustice in the education of IPs in the Philippines.

My aim in this article is to propose that an insightful way of articulating the feminist concept of epistemic injustice can be provided by paying significant attention to recognition theory. The article intends to provide an account for diagnosing epistemic injustice as a social pathology and also attempts to paint a picture of some social cure of structural forms of epistemic injustice. While there are many virtues to the literature on epistemic injustice, epistemic exclusion and (...) silencing, current discourse on diagnosing as well as explicating and overcoming these social pathologies can be improved and enriched by bringing recognition theory into the conversation: under recognition theory, social normative standards are constructed out of the moral grammar of recognition attributions. I shall argue that the failure to properly recognize and afford somebody or a social group the epistemic respect they merit is an act of injustice in the sense of depriving individuals of a progressive social environment i...

In this paper, I introduce the emerging theory of judgment aggregation as a framework for studying institutional design in social epistemology. When a group or collective organization is given an epistemic task, its performance may depend on its ‘aggregation procedure’, i.e. its mechanism for aggregating the group members’ individual beliefs or judgments into corresponding collective beliefs or judgments endorsed by the group as a whole. I argue that a group’s aggregation procedure plays an important role in determining whether the (...) group can meet two challenges: the ‘rationality challenge’ and the ‘knowledge challenge’. The rationality challenge arises when a group is required to endorse consistent beliefs or judgments; the knowledge challenge arises when the group’s beliefs or judgments are required to track certain truths. My discussion seeks to identify those properties of an aggregation procedure that affect a group’s success at meeting each of the two challenges. (shrink)

This essay raises new objections to the two dominant approaches to understanding the justification of group beliefs—_inflationary_ views, where groups are treated as entities that can float freely from the epistemic status of their members’ beliefs, and _deflationary_ views, where justified group belief is understood as nothing more than the aggregation of the justified beliefs of the group's members. If this essay is right, we need to look in an altogether different place for an adequate account of justified (...) group belief. From these objections emerges the skeleton of the positive view that this essay goes on to develop and defend, called the _group epistemic agent account_: groups are epistemic agents in their own right, with justified beliefs that respond to both evidence and normative requirements that arise only at the group level but that are nonetheless importantly constrained by the epistemic status of the beliefs of their individual members.

How a group G can know that p has been the subject of much investigation in social epistemology in recent years. This paper clarifies and defends a form of non-supervenient, non-summative group knowledge: G can know that p even if none of the members of G knows that p, and whether or not G knows that p does not locally supervene on the mental states of the members of G. Instead, we argue that what is central to G knowing that (...) p is whether G has an epistemic structure that is functioning appropriately in accord with the action-related purposes of the group, and this structure may include non-agential elements such as devices that retain or process information. We argue that recent objections to non-summative group knowledge given by Jennifer Lackey do not in fact succeed in undermining the view, but do help to clarify the nature of non-summative group knowledge. The main upshot of our response to Lackey’s objections is that groups put their knowledge into action in ways that often differ from how individuals do so, and social epistemologists should be careful to notice these differences, especially insofar as groups often structure themselves by employing various epistemically-relevant devices.

The present book continues Rescher s longstanding practice of publishing groups of philosophical essays that originated in occasional lecture and conference presentations. Notwithstanding their topical diversity they exhibit a uniformity of method in a common attempt to view historically significant philosophical issues in the light of modern perspectives opened up through conceptual clarification.".

This article introduces the concept of epistemic positioning to theorize the relationship between identity-based epistemic judgements and the reproduction of social inequalities, including those of gender and ethnicity/race, in the academia. Acts of epistemic positioning entail the evaluation of knowledge claims based on the speaker’s stated or inferred identity. These judgements serve to limit the scope of the knowledge claim, making it more likely speakers will be denied recognition or credit. The four types of epistemic positioning (...) – bounding (reducing a knowledge claim to elements of personal identity), domaining (reducing a knowledge claim to discipline or field associated with identity), non-attribution (using the claim without recognizing the author) and appropriation (presenting the claim as one’s own) – are mutually reinforcing. Given the growing importance of visibility and recognition in the context of increasing competition and insecurity in academic employment, these practices play a role in the ability of underrepresented groups to remain in the academic profession.

At the intersection of social and virtue epistemology lies the important, yet so far entirely neglected, project of articulating the social dimensions of epistemic virtues. Perhaps the most obvious way in which epistemic virtues might be social is that they may be possessed by social collectives. We often speak of groups as if they could instantiate epistemic virtues. It is tempting to think of these expressions as ascribing virtues not to the groups themselves, but to (...) their members. Adapting Margaret Gilbert's arguments against individualist accounts of collective beliefs, I show that individualist accounts of group virtues are either too weak or too strong. I then formulate a non-individualist account modeled after Gilbert's influential account of collective beliefs. A crucial disanalogy between collective traits and beliefs, I argue, makes the success of this model unlikely. I conclude with some questions with which the future work on collective epistemic virtues should engage. (shrink)

A long-standing debate in group ontology and group epistemology concerns whether some groups possess mental states and/or epistemic states such as knowledge that do not reduce to the mental states and/or epistemic states of the individuals who comprise such groups (and are also states not possessed by any of the members). Call those who think there are such states inflationists. There has recently been a defense in the literature of a specific type of inflationary knowledge—viz., knowledge (...) of facts about group minds or group self-knowledge (GS-K). In this paper I address whether some groups do possess such knowledge. I argue that we have good reason to think they do not. I do so by exploring the most explicit defense of such knowledge in the literature—Lukas Schwengerer’s (2022) defense—as well as other ways of defending this thesis and arguing that such ways are problematic. In the latter part of the paper, I explain why the two most popular inflationary approaches to group knowledge simpliciter are incompatible with there being GS-K. In doing so I work to show why even inflationists should reject the view that there is inflationary group self-knowledge. (shrink)

In this paper, we discuss specific epistemic injustices suffered by gender minorities in the Philippines. We also show that societal changes have been evident throughout the years. We review some progressive Philippine Catholic communities' sustainable development efforts toward gender equality or toward the eradication of discrimination, marginalisation, and violence based on a person's sexual orientation, gender identity, or gender expression (SOGIE). Despite these epistemic injustices, we reveal that there are ways by which gender disorientations may be disrupted by (...) progressive Philippine Catholic groups and communities in the era of contemporary Christianities.

Epistemic injustice is a harm done to a person in their capacity as an epistemic subject by undermining her capacity to engage in epistemic practices such as giving knowledge to others or making sense of one’s experiences. It has been argued that those who suffer from medical conditions are more vulnerable to epistemic injustice than the healthy. This paper claims that people with mental disorders are even more vulnerable to epistemic injustice than those with somatic (...) illnesses. Two kinds of contributory factors for epistemic injustice in psychiatric patients are outlined: global and specific. Some suggestions are made to counteract the effects of these contributory factors, for instance we suggest that physicians should participate in groups where the subjective experience of patients is explored, and learn to become more aware of their own unconscious prejudices towards psychiatric patients.
