This article discusses African feminist approaches to decolonization and social transformation. In recent years, there has been a significant shift in African feminist scholarship towards African concerns and Africa-centered solutions. Today’s turn to Indigenous knowledge, social structures, and gender relations is no longer just about shedding light on the precolonial past, but about fundamentally changing the epistemic framework in the sense of developing alternative epistemologies beyond the dominant ‘Western’ framework. But what is meant by ‘alternative epistemologies’? How do African (...) feminist thinkers conceptualize social change today? And how do they relate epistemic and social change in their thinking? These questions are explored in this article, focusing on work by Sylvia Tamale (Uganda), Wangari Maathai (Kenya), and Anthonia Kalu (Nigeria) and drawing on the discourse of ecofeminism and Ubuntu as two models of alternative epistemologies.

Since its inception in the early 1990s, evidence-based medicine (EBM) has become the dominant epistemic framework for Western medical practice. However, in light of powerful criticisms against EBM, alternatives such as casuistic medicine have been gaining support in both the medical and philosophical community. In the absence of empirical evidence in support of the claim that EBM improves patient outcomes, and in light of considerations that it is unlikely that such evidence will be forthcoming, another standard is needed to (...) assess EBM against its alternatives. In this paper, I propose a set of criteria for this purpose based on Helen Longino's criteria for assessing the objectivity of a knowledge productive community. I then apply these criteria to assess EBM against a casuistic framework for medical knowledge. I argue that EBM's strict adherence to a hierarchical organization of knowledge can reasonably be expected to block it from fulfilling a high level of objectivity. A casuistic framework, on the other hand, because it emphasizes critical evaluation in conjunction with the flexibility of a case-based approach, could be expected to better facilitate a more optimal epistemic community.

This paper has four aims: first, to outline the role of the sceptical problem of the criterion in the principal argument for epistemic relativism; second, to establish that methodist and particularist responses to the problem of the criterion do not, by themselves, constitute successful strategies for resisting epistemic relativism; third, to argue that a more fruitful strategy is to attempt to evaluate epistemic frameworks on the basis of the epistemic resources that they have in common; (...) and finally, to make the case that finding this common ground will necessarily involve determining how it is that a framework’s constituent epistemic methods depend on one another for not only their warrant, but for their application.

© The Author, 2017. Published by Oxford University Press. All rights reserved. In this article, we introduce a lightweight dynamic epistemic logical framework for automated planning under initial uncertainty. We generalize the standard conformant planning problem in AI in two crucial aspects: first, the planning goal can be any formula expressed in an epistemic propositional dynamic logic ; second, procedural constraints of the desired plan specified by regular expressions can be imposed. We then reduce the problem of generalized (...) conformant planning to the model checking problem of our logic. Although our conformant planning problem is much more general than the standard one with Boolean goals and no procedural constraints, the complexity is still PSPACE-complete which is equally hard as standard conformant planning over explicit transition systems.

Calls for incorporating social science into patient care typically have accounted for neither the logistic constraints of medical training nor the methodological fallacies of utilizing aggregate “social facts” in clinical practice. By elucidating the different epistemic approaches of artistic and scientific practices, this paper illustrates an integrative artistic pedagogy that allows clinical practitioners to generate social scientific insights from actual patient encounters. Although there is no shortage of calls to bring social science into medicine, the more fundamental processes of (...) thinking by which art and science proceed have not been addressed to this end. As such, the art of medical practice is conceptualized as an innate gift, and thus little is done to cultivate it. Yet doing so is more important than ever because uncertainty in diagnosing and treating chronic illnesses, the most significant contemporary mortality risks, suggests a re-expanding role for clinical judgment.

Recent years witnessed a growing interest in non-standard epistemic logics of knowing whether, knowing how, knowing what, knowing why and so on. The new epistemic modalities introduced in those logics all share, in their semantics, the general schema of ∃x◻φ, e.g., knowing how to achieve φ roughly means that there exists a way such that you know that it is a way to ensure that φ. Moreover, the resulting logics are decidable. Inspired by those particular logics, in this (...) work, we propose a very general and powerful framework based on quantifier-free predicate language extended by a new modality, which packs exactly ∃x◻ together. We show that the resulting language, though much more expressive, shares many good properties of the basic propositional modal logic over arbitrary models, such as finite-tree-model property and van Benthem-like characterization w.r.t.\ first-order modal logic. We axiomatize the logic over S5 frames with intuitive axioms to capture the interaction between the new modality and know-that operator in an epistemic setting. (shrink)

How can we make businesspeople more concerned about the truth of the information they spread or allow to circulate? In this age of ‘fake news’, ‘business bullshit’ and ‘post-truth,’ the issue is of the utmost importance, especially for business trustworthiness in the internet economy. The issue is related to a kind of epistemic responsibility, that consists in accounting for one’s own epistemic wrongdoings, such as making a third party believe something false. Despite growing interest in epistemic misbehavior (...) in the literature of business ethics, the question of epistemic responsibility has been neglected. The aim of this paper is therefore to address this gap, by proposing a notion of epistemic responsibility for business, that may help regulate undesirable epistemic behavior, such as the spreading of false information. To define this notion of epistemic responsibility, I have introduced the concept of epistemic fault. Being epistemically responsible consists in being disposed to account for alleged epistemic faults. This notion of epistemic fault relies on a theoretical framework which combines a typology of eight ‘epistemic values’, a normative stance regarding these values, and a dispositional approach to epistemic virtues and vices. I use this theoretical framework to integrate the various accounts of epistemic virtues and vices found in the literature into a single explanatory scheme. Combined with the notion of epistemic responsibility itself, such an integrative framework should facilitate the practical application of an operational epistemic ethics in business, i.e., the development of virtuous epistemic practices.

This paper seeks to exhibit and explain, by way of comparison, two ideal kinds of knowledge: knowledge based on classifications according to genera and species, as in Aristotelianism and common sense, and scientific knowledge based on the application of laws of nature. I will proceed by attempting (1) to determine the role that presuppositions play in knowledge in general by means of the distinction between content and form; (2) to describe and explain the main features of both ideal forms of (...) knowledge; and, finally, (3) to analyze the relation between these two forms of knowledge as it is presented in Eddington's celebrated discussion of the “two tables”. I will be critical of the widespread view that modern science is the correct form of knowledge, and that common sense is merely an illusion. (shrink)

In this position paper, we introduce a new epistemic lens for analyzing algorithmic harm. We argue that the epistemic lens we propose herein has two key contributions to help reframe and address some of the assumptions underlying inquiries into algorithmic fairness. First, we argue that using the framework of epistemic injustice helps to identify the root causes of harms currently framed as instances of representational harm. We suggest that the epistemic lens offers a theoretical foundation for (...) expanding approaches to algorithmic fairness in order to address a wider range of harms not recognized by existing technical or legal definitions. Second, we argue that the epistemic lens helps to identify the epistemic goals of inquiries into algorithmic fairness. There are two distinct contexts within which we examine algorithmic harm: at times, we seek to understand and describe the world as it is, and, at other times, we seek to build a more just future. The epistemic lens can serve to direct our attention to the epistemic frameworks that shape our interpretations of the world as it is and the ways we envision possible futures. Clarity with respect to which epistemic context is relevant in a given inquiry can further help inform choices among the different ways of measuring and addressing algorithmic harms. We introduce this framework with the goal of initiating new research directions bridging philosophical, legal, and technical approaches to understanding and mitigating algorithmic harms. (shrink)

Since Hintikka’s epistemic logic, the logic of knowledge, has been a subject of research in philosophy, computer science, artificial intelligence and game theory. This paper presents a framework of dynamic epistemic logic capable of investigating interactive voting decisions in liquid democracy.

This article argues that the Teaching Excellence Framework manifests the vice of epistemic insensibility. To this end, it explains that the TEF is a metrics‐driven evaluation mechanism which permits English higher education institutions to charge higher fees if the ‘quality’ of their teaching is deemed ‘excellent’. Through the TEF, the Government aims to improve the quality of teaching by using core metrics that reflect student satisfaction, retention and short‐term graduate employment. In response, some have criticised the TEF for failing (...) to meaningfully evaluate the quality of teaching. This article seeks to explain and justify this criticism. It thus presents Heather Battaly's account of the vice of epistemic insensibility and argues that the TEF manifests two key features of an epistemically insensible policy, namely: it promotes a failure to desire, consume and enjoy epistemic goods that it is appropriate to desire, consume and enjoy; and it does so because it is committed to a false conception of the epistemic good. Crucially, it argues that the TEF falsely assumes that epistemic goods that serve to bolster its core metrics are more valuable than epistemic goods that do not. The article thus shows how this relies on an erroneous conception of the purpose of education and thus a false conception of the epistemic good. Finally, the article considers two brief objections and concludes that the TEF advances a conception of the student‐as‐customer which detracts from desiring, consuming and enjoying epistemic goods related to edification, civic participation and the student‐teacher relationship.

There are two central kinds of epistemological mistakes: believing things you shouldn’t, and failing to believe things that you should. The knowledge-first program offers a canonical explanation for the former: if you believe something without knowing it, you violate the norm to believe only that which you know. But the explanation does not extend in any plausible way to a story about what’s wrong with suspending judgment when one ought to believe. In this paper I explore prospects for a knowledge-centering (...) account of positive epistemic norms that describe epistemic duties to believe. (shrink)

While such epistemic rules as 'If you perceive that X, you ought to believe that X' and 'If you have outstanding testimony that X, you ought to believe that X' seem to be getting at important truths, it is easy to think of cases in which they come into conflict. To avoid classifying such cases as dilemmas, one can hold either that epistemic rules have built-in unless-clauses listing the circumstances under which they don't apply, or, alternatively, that (...) class='Hi'>epistemic rules are contributory. This paper explores both responses from a formal perspective, drawing on a simple defeasible logic framework. (shrink)

The term “epistemic shifts” refers to a widely recognized phenomenon that knowledge ascribers would ascribe different epistemic statuses to the same belief under different internal/external conditions. Mainstream theories explaining shifts can all be assimilated into a probabilistic framework, according to which the epistemic status of a belief P can be at least partially evaluated in terms of the strength of the link between this belief and its normal truth-maker, namely, a P-corresponding fact, and the strength of this (...) link can be further probabilistically measured in terms of the knowledge-undermining force of an “abnormal” truth-maker of P, namely, a P-inducing fact which itself is not a P-corresponding fact simpliciter. I will further claim that by accepting my framework, a theorist of shifts has to tolerate a pluralist view of the etiology of shifts on the philosophical level, and mainstream theories explaining shifts are flawed in the sense that they all attempt to exaggerate one single and particular factor underpinning shifts by ignoring others.

PROBABILISTIC APPROACH TO EPISTEMIC MODALS IN THE FRAMEWORK OF DYNAMIC SEMANTICS In dynamic semantics meaning of a statement is not equated with its truth conditions but with its context change potential. It has also been claimed that dynamic framework can automatically account for certain paradoxes that involve epistemic modals, such as the following one: it seems odd and incoherent to claim: (1) “It is raining and it might not rain”, whereas claiming (2) “It might not rain and it (...) is raining” does not seem equally odd (Yalcin, 2007). Nevertheless, it seems that it cannot capture the fact that statement (2) seems odd as well, even though not as odd as the statement (1) (Gauker, 2007). I will argue that certain probabilistic extensions to the dynamic model can account for this subtlety of our linguistic intuitions and represent if not an improved than at least an alternative framework for capturing the way contexts are updated and beliefs revised with uncertain information.

In this paper, I carry out a philosophical analysis of the structural power that Miranda Fricker proposes in Epistemic Injustice starting from the idea of the “interpretative frame” that Judith Butler elaborates in Frames of war. The relationship between the two concepts aims to explore how structural power generates, through the frame, certain epistemic blindnesses to hinder the identification of epistemic harms. To do so, first, I analyze the functioning of the interpretive frame and highlight how it (...) operates by establishing an inside (what is recognized) and an outside (what is rejected) of it. Secondly, I examine the possibilities of freeing perception from the norms of the interpretative frame. Finally, based on the work of José Medina, I propose a praxis of the gaze that consists in apprehending and recognizing what the frame rejects and tries to hide from the gaze. (shrink)

Epistemic exploitation occurs when privileged persons compel marginalized persons to educate them about the nature of their oppression. I argue that epistemic exploitation is marked by unrecognized, uncompensated, emotionally taxing, coerced epistemic labor. The coercive and exploitative aspects of the phenomenon are exemplified by the unpaid nature of the educational labor and its associated opportunity costs, the double bind that marginalized persons must navigate when faced with the demand to educate, and the need for additional labor created (...) by the default skepticism of the privileged. I explore the connections between epistemic exploitation and the two varieties of epistemic injustice that Fricker (2007) identifies, testimonial and hermeneutical injustice. I situate epistemic exploitation within Dotson’s (2012; 2014) framework of epistemic oppression, and I address the role that epistemic exploitation plays in maintaining active ignorance and upholding dominant epistemic frameworks.

We outline an intuitionistic view of knowledge which maintains the original Brouwer–Heyting–Kolmogorov semantics for intuitionism and is consistent with the well-known approach that intuitionistic knowledge be regarded as the result of verification. We argue that on this view coreflectionA→KAis valid and the factivity of knowledge holds in the formKA→ ¬¬A‘known propositions cannot be false’.We show that the traditional form of factivityKA→Ais a distinctly classical principle which, liketertium non datur A∨ ¬A, does not hold intuitionistically, but, along with the whole of (...) classical epistemic logic, is intuitionistically valid in its double negation form ¬¬(KA¬A).Within the intuitionistic epistemic framework the knowability paradox is resolved in a constructive manner. We argue that this paradox is the result of an unwarranted classical reading of constructive principles and as such does not have the consequences for constructive foundations traditionally attributed it.

We propose a general framework for dynamic epistemic logics. It consists of a generic language for DELs and a class of structures, called model transition systems, that describe model transformations in a static way. An MTS can be viewed as a two-layered Kripke model and consequently inherits standard concepts such as bisimulation and bounded morphism from the ordinary Kripke models. In the second half of this article we add the global operator to the language, which enables us to define (...) the notions of a canonical MTS and canonicity of a DEL formula for a property of MTSs. Using these notions, we clarify correspondences between axioms of DELs and properties of MTSs. (shrink)

This paper proposes a conceptual framework for evaluating how social networking platforms fare as epistemic environments for human users. I begin by proposing a situated concept of epistemic agency as fundamental for evaluating epistemic environments. Next, I show that algorithmic personalisation of information makes social networking platforms problematic for users’ epistemic agency because these platforms do not allow users to adapt their behaviour sufficiently. Using the tracing principle inspired by the ethics of self-driving cars, I operationalise (...) it here and identify three requirements that automated epistemic environments need to fulfil: (a) the users need to be afforded a range of skilled actions; (b) users need to be sensitive to the possibility to use their skills; (c) the habits built when adapting to the platform should not undermine the user’s pre-existing skills. I then argue that these requirements are almost impossible to fulfil all at the same time on current SN platforms; yet nevertheless, we need to pay attention to these whenever we evaluate an epistemic environment with automatic features. Finally, as an illustration, I show how Twitter, a popular social networking platform, will fare regarding these requirements. (shrink)

This paper proposes a view on epistemic relativism that arises from the problem of the criterion, keeping in consideration that the assessment of criterion standards always occurs in a certain context. The main idea is that the epistemic value of the assertion “S knows that p” depends not only on the criterion adopted within an epistemic framework and the relationship between said criterion and a meta-criterion, but also from the collaboration with other subjects who share the same (...) standards. Thus, one can choose between particularist and methodist criteria according to the context of assessment. This position has the advantage of presenting a new perspective concerning both the criterion problem and the problem of inter-contextuality in the evaluation of different epistemic frameworks.

Epistemic logic is one of the most exciting areas in medieval philosophy. Neglected almost entirely after the end of the Middle Ages, it has been rediscovered by philosophers of the twentieth century. Epistemic Logic in the Later Middle Ages provides the first comprehensive study of the subject. Ivan Boh explores the contrast between epistemic and alethic conceptions of consequence, the general epistemic rules of consequence, the search for conditions of knowing contingent propositions, the problems of substitutivity (...) in intentional contexts, the considerations of epistemic/doxastic iterated modalities, and the problems of composite and divided senses in authors ranging from Abelard to Frachantian. Boh concludes with a comparison between medieval endeavors and the epistemic logic of our own times. Written in a clear and readable style with minimal symbolic apparatus, this book employs modern symbolism and conceptual frameworks, and complements the studies of the syntacticand semantic dimensions of medieval logic.

Abstract. Traditional epistemology of knowledge and belief can be succinctly characterized as JTB-epistemology, i.e., it is characterized by the thesis that knowledge is justified true belief. Since Gettier’s trail-blazing paper of 1963 this account has become under heavy attack. The aim of is paper is to study the Gettier problem and related issues in the framework of topological epistemic logic. It is shown that in the framework of topological epistemic logic Gettier situations necessarily occur for most topological models (...) of knowledge and belief. On the other hand, there exists a special class of topological models (based on so called nodec spaces) for which traditional JTB-epistemology is valid. Further, it is shown that for each topological model of Stalnaker’s combined logic KB of knowledge and belief a canonical JTB-model (its JTB-doppelganger) can be constructed that shares many structural properties with the original model but is free of Gettier situations. The topological model and its JTB-doppelganger both share the same justified belief operator and have very similar knowledge operators. Seen from a somewhat different perspective, the JTB-account of epistemology amounts to a simplification of a more general epistemological account of knowledge and belief that assumes that these two concepts may differ in some cases. The JTB-account of knowledge and belief assumes that the epistemic agent’s cognitive powers are rather large. Thereby in the JTB-epistemology Gettier cases do not occur. Eventually, it is shown that for all topological models of Stalnaker’s KB-logic Gettier situations are topologically characterized as nowhere dense situations. This entails that Gettier situations are epistemologically invisible in the sense that they can neither be known nor believed with justification with respect to the knowledge operator and the belief operator of the models involved.

We present epistemic multilateral logic, a general logical framework for reasoning involving epistemic modality. Standard bilateral systems use propositional formulae marked with signs for assertion and rejection. Epistemic multilateral logic extends standard bilateral systems with a sign for the speech act of weak assertion (Incurvati and Schlöder 2019) and an operator for epistemic modality. We prove that epistemic multilateral logic is sound and complete with respect to the modal logic S5 modulo an appropriate translation. The (...) logical framework developed provides the basis for a novel, proof-theoretic approach to the study of epistemic modality. To demonstrate the fruitfulness of the approach, we show how the framework allows us to reconcile classical logic with the contradictoriness of so-called Yalcin sentences and to distinguish between various inference patterns on the basis of the epistemic properties they preserve.

This article introduces a novel theoretical framework for addressing epistemic injustice—a phenomenon where certain groups or individuals are systematically excluded from knowledge creation and dissemination processes—by employing ontological relativity and conceptual analysis. “Ontological relativity” refers to a philosophical perspective that posits our understanding of reality as being shaped by our toolbox of concepts, categories, language, and social practices; “conceptual analysis” is a method of inquiry that involves the rigorous examination and deconstruction of a particular concept or set of concepts (...) in order to uncover their constituent elements, relationships, and underlying assumptions. To exemplify the effectiveness of the ontology‐based approach, two paradigmatic applications are explored: (a) educational practices and (b) clinical practice and access to health care. Through the presentation of these applications and the step‐by‐step illustration of the applied methodology, the aim of the article is to showcase the efficacy of ontology in tackling epistemic injustices, suggesting innovative paths for future research in this domain.

The discussion presents a framework of concepts that is intended to account for the rationality of semantic change and variation, suggesting that each scientific concept consists of three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept’s use. I argue that in the course of history a concept can change in any of these components, and that change in the concept’s inferential role and reference can be accounted for as being rational (...) relative to the third component, the concept’s epistemic goal. This framework is illustrated and defended by application to the history of the gene concept. It is explained how the molecular gene concept grew rationally out of the classical gene concept despite a change in reference, and why the use and reference of the contemporary molecular gene concept may legitimately vary from context to context.

There is an important disagreement in contemporary epistemology over the possibility of non-epistemic reasons for belief. Many epistemologists argue that non-epistemic reasons cannot be good or normative reasons for holding beliefs: non-epistemic reasons might be good reasons for a subject to bring herself to hold a belief, the argument goes, but they do not offer any normative support for the belief itself. Non-epistemic reasons, as they say, are just the wrong kind of reason for belief. Other (...) epistemologists, however, argue that there can be cases where non-epistemic reasons directly offer normative support for the beliefs a subject holds. -/- My aim in this paper is to remove an apparent obstacle for the view that there can be non-epistemic normative reasons for belief, by showing that the existence of non-epistemic reasons for belief does not conflict with epistemic standards for the assessment of inference. More specifically, I aim to show that the following principles are compatible: -/- Epistemic Norm of Inference (ENI): Necessarily, for all subjects, S, and inferences, I: I is a good inference for S only if S can gain a (doxastically) epistemically justified belief in I’s conclusion on the basis of I’s premises. -/- Non-Epistemic Reasons for Belief (NERB): Possibly, for some subject, S, reason, R, and belief, B: R is a good (i.e., normative) reason for S to hold B, and R is not an epistemic reason for B. -/- Guidance: For all subjects S, potential reasons R, and beliefs/actions φ: In order for R to count as a normative reason for S to φ, it must be possible for S to take R into account as relevant to the determination of whether S ought to φ. -/- One might naturally think that these principles conflict, for if there are non-epistemic reasons for belief, then they must guide deliberation, and in guiding deliberation, they would violate epistemic standards. The aim of this paper is to show that no such conflict need arise. -/- Section 2 of the paper proceeds to set out the concept of an inference, and to sketch an epistemic framework for the assessment of inferences and arguments. Section 3 sets out the distinction between normative and motivating reasons, and briefly defends the view that there can be non-epistemic reasons for beliefs. Section 4 shows that non-epistemic reasons for belief are compatible with epistemic standards for inference, because any time a reason R is a good non-epistemic reason for a subject S to hold a belief B, there is an epistemically good inference available to S which takes R as a premise and which concludes with the meta-belief that S ought to hold B. So the paper employs a level-connecting principle between normative reasons for φ-ing and epistemic reasons for believing that one ought to φ. The paper ends with clarifications of that level-connecting principle, and responses to three objections. (shrink)

Epistemic logic with its possible worlds semantic model is a powerful framework that allows us to represent an agent’s information not only about propositional facts, but also about her own information. Nevertheless, agents represented in this framework are logically omniscient: their information is closed under logical consequence. This property, useful in some applications, is an unrealistic idealisation in some others. Many proposals to solve this problem focus on weakening the properties of the agent’s information, but some authors have argued (...) that solutions of this kind are not completely adequate because they do not look at the heart of the matter: the actions that allow the agent to reach such omniscient state. Recent works have explored how acts of observation, inference, consideration and forgetting affect an agent’s implicit and explicit knowledge; the present work focuses on acts that affect an agent’s implicit and explicit beliefs. It starts by proposing a framework in which these two notions can be represented, and then it looks into their dynamics, first by reviewing the existing notion of belief revision, and then by introducing a rich framework for representing diverse forms of inference that involve both knowledge and beliefs.

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a (...) noetic system and thereby prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.

Why comply with epistemic norms? In this paper, I argue that complying with epistemic norms, engaging in epistemically responsible conduct, and being epistemically trustworthy are constitutive elements of maintaining good epistemic relations with oneself and others. Good epistemic relations are in turn both instrumentally and finally valuable: they enable the kind of coordination and knowledge acquisition underpinning much of what we tend to associate with a flourishing human life; and just as good interpersonal relations with others (...) can be good for their own sake, standing in good epistemic relations is good for its own sake. On my account, we have reason to comply with epistemic norms because it is a way of respecting the final value of something that also tends to be an instrumentally valuable thing: good epistemic relations. Situating the account within the recent social turn in debates about epistemic instrumentalism, I argue that the dual-value aspect of good epistemic relations can explain important anti-instrumentalist intuitions, in a well-motivated way, within a broadly instrumentalist framework.

Epistemic modals have peculiar logical features that are challenging to account for in a broadly classical framework. For instance, while a sentence of the form $$p\wedge \Diamond \lnot p$$ (‘p, but it might be that not p’) appears to be a contradiction, $$\Diamond \lnot p$$ does not entail $$\lnot p$$, which would follow in classical logic. Likewise, the classical laws of distributivity and disjunctive syllogism fail for epistemic modals. Existing attempts to account for these facts generally either under- (...) or over-correct. Some theories predict that $$ p\wedge \Diamond \lnot p$$, a so-called epistemic contradiction, is a contradiction only in an etiolated sense, under a notion of entailment that does not always allow us to replace $$p\wedge \Diamond \lnot p$$ with a contradiction; these theories underpredict the infelicity of embedded epistemic contradictions. Other theories savage classical logic, eliminating not just rules that intuitively fail, like distributivity and disjunctive syllogism, but also rules like non-contradiction, excluded middle, De Morgan’s laws, and disjunction introduction, which intuitively remain valid for epistemic modals. In this paper, we aim for a middle ground, developing a semantics and logic for epistemic modals that makes epistemic contradictions genuine contradictions and that invalidates distributivity and disjunctive syllogism but that otherwise preserves classical laws that intuitively remain valid. We start with an algebraic semantics, based on ortholattices instead of Boolean algebras, and then propose a possibility semantics, based on partial possibilities related by compatibility. Both semantics yield the same consequence relation, which we axiomatize. We then show how to lift an arbitrary possible worlds model for a non-modal language to a possibility model for a language with epistemic modals. The goal throughout is to retain what is desirable about classical logic while accounting for the non-classicality of epistemic vocabulary. (shrink)

This book aims to distinguish acceptable from unacceptable interest influences in science. Jan De Winter criticizes existing views on the integrity of science and the roles of financial, political, and other interests in science, and develops an alternative view to shed new light on cases from medical science, aerospace science, climate science, and biology.

In this chapter, I propose a new framework for extended epistemology, based on a second-wave approach to extended cognition. The framework is inclusive, in that it takes into account the complex interplay between the diverse embodiments of extended knowers and the salient properties of technological artifacts, as well as the environment in which they are embedded. Thus it both emphasizes and exploits the complementary roles played by these different elements. Finally, I motivate and explain this framework by applying it to (...) a case of interaction with contemporary technologies. (shrink)

Focusing on cases which involve binding into epistemic modals with definite descriptions and quantifiers, I raise some new problems for standard approaches to all of these expressions. The difficulties are resolved in a semantic framework that is dynamic in character. I close with a new class of problems about de re readings within the scope of modals.

Diagnostic frameworks are essential to many scientific and technological activities and clinical practice. This study examines the main fundamental aspects of such frameworks. The three components required for all diagnoses are identified and examined, i.e. their normative dimension, temporal nature and structure, and teleological perspective.The normative dimension of a diagnosis is based on (1) epistemic values when associated with Hempel's inductive risk concerning the balance between false‐positive and false‐negative outcomes, leading to probabilistic judgements; and (2) non‐epistemic (...) values when related to ideas such as well‐being, normality, illness, etc, as idealized norms or ideal points of reference.It should be noted that medical diagnoses match the three necessary components, while some essential diagnostic frameworks – the taxonomies ofGordon andNANDA– in nursing lack some components. The main lack is normative as the most popular frameworks in nursing diagnosis seem to be descriptions of observed reality rather than normative and value‐based judgements in which both epistemic and non‐epistemic values may coexist.

Information exchange can be seen as a dynamic process of raising and resolving issues. The goal of this paper is to provide a logical framework to model and reason about this process. We develop an inquisitive dynamic epistemic logic , which enriches the standard framework of dynamic epistemic logic , incorporating insights from recent work on inquisitive semantics. At a static level, IDEL does not only allow us to model the information available to a set of agents, like (...) standard epistemic logic, but also the issues that the agents entertain. At a dynamic level, IDEL does not only allow us to model the effects of communicative actions that provide new information, like standard DEL, but also the effects of actions that raise new issues. Thus, IDEL provides the fundamental tools needed to analyze information exchange as a dynamic process of raising and resolving issues. (shrink)

Traditional epistemology of knowledge and belief can be succinctly characterized as JTB-epistemology, i.e., it is characterized by the thesis that knowledge is justified true belief. Since Gettier’s trail-blazing paper of 1963 this account has become under heavy attack. The aim of is paper is to study the Gettier problem and related issues in the framework of topological epistemic logic. It is shown that in the framework of topological epistemic logic Gettier situations necessarily occur for most topological models of (...) knowledge and belief. On the other hand, there exists a special class of topological models (based on so called nodec spaces) for which traditional JTB-epistemology is valid. Further, it is shown that for each topological model of Stalnaker’s combined logic KB of knowledge and belief a canonical JTB-model (its JTB-doppelganger) can be constructed that shares many structural properties with the original model but is free of Gettier situations. The topological model and its JTB-doppelganger both share the same justified belief operator and have very similar knowledge operators. Seen from a somewhat different perspective, the JTB-account of epistemology amounts to a simplification of a more general epistemological account of knowledge and belief that assumes that these two concepts may differ in some cases. The JTB-account of knowledge and belief assumes that the epistemic agent’s cognitive powers are rather large. Thereby in the JTB-epistemology Gettier cases do not occur. Eventually, it is shown that for all topological models of Stalnaker’s KB- logic Gettier situations are topologically characterized as nowhere dense situations. This entails that Gettier situations are epistemologically invisible in the sense that they can neither be known nor believed with justification with respect to the knowledge operator and the belief operator of the models involved. Keywords. Stalnaker’s logic KB of knowledge and belief; Topological epistemology; Epistemic Invisibility; Doxastic invisibility; Gettier cases; . (shrink)

Epistemologists spend a great deal of time thinking about how we should respond to our evidence. They spend far less time thinking about the ways that evidence can be acquired in the first place. This is an oversight. Some ways of acquiring evidence are better than others. Many normative epistemologies struggle to accommodate this fact. In this article I develop one that can and does. I identify a phenomenon – epistemic feedback loops – in which evidence acquisition has gone (...) awry, with the result that even beliefs based on the evidence are irrational. Examples include evidence acquired under the influence of confirmation bias and evidence acquired under the influence of cognitively penetrated experiences caused by implicit bias. I then develop a theoretical framework which enables us to understand why beliefs that are the outputs of epistemic feedback loops are irrational. Finally, I argue that many popular approaches to epistemic normativity may need to be abandoned on the grounds that they cannot comfortably explain feedback loops. The scope of this last claim is broad: it includes almost all contemporary theories of justified/rational belief and of the epistemology of cognitive penetration. (shrink)

This paper provide the first extended discussion in the philosophical literature of the epistemic significance of the phenomenon of “being known” and the relationship it has to reparations that are distinctively epistemic. Drawing on a framework provided by the United Nations of the “right to know,” it is argued that victims of gross violations and injustices not only have the right to know what happened, but also the right to be known—to be a giver of knowledge to others (...) about their own experiences. It is shown that such victims can suffer epistemic wrongs by being rendered invisible, vilified or demonized, or systematically distorted, and that these ways of not being known demand epistemic reparations. While there are traditional reparations that are epistemic in nature, such as memorialization and education, it is argued that there is a prior and arguably more important epistemic reparation—knowing victims of gross violations and injustices in the sense of bearing witness. The paper concludes with a sketch of an epistemological picture to underwrite this notion of epistemic reparations, one that significantly expands the traditional picture by including epistemic duties that are imperfect in nature and concern actions in addition to beliefs.

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)

The article introduces substructural epistemic logics of belief supported by evidence. The logics combine normal modal epistemic logics with distributive substructural logics. Pieces of evidence are represented by points in substructural models and availability of evidence is modelled by a function on the point set. The main technical result is a general completeness theorem. Axiomatisations are provided by means of two-sorted Hilbert-style calculi. It is also shown that the framework presents a natural solution to the problem of logical (...) omniscience. (shrink)

Epistemic dependence refers to our social mechanisms of reliance in practices of knowledge production. Epistemic oppression concerns persistent and unwarranted exclusions from those practices. This article examines the relationship between these two frameworks and demonstrates that attending to their relationship is a fruitful practice for applied epistemology. Paying attention to relations of epistemic dependence and how exclusive they are can help us track epistemically oppressive practices. In order to show this, I introduce a taxonomy of (...) class='Hi'>epistemic dependence. I argue that this particular taxonomy is useful for tracking epistemically oppressive practices in institutional contexts. This is because, first, the forms of epistemic dependence in this taxonomy yield, what I call, diagnostic questions. These are questions that help us track how relations of epistemic dependence could become exclusive and that thus help reveal epistemic oppression in institutional contexts. Second, the forms of epistemic dependence in the taxonomy are interrelated. Paying attention not just to each of three forms of epistemic dependence but also to the way in which they are interrelated is useful for illuminating epistemically oppressive practices. I conclude by demonstrating how the diagnostic questions can be used in analyses of concrete institutional practices in asylum law and higher education. (shrink)

On the one hand, there seem to be compelling parallels to moral responsibility, blameworthiness, and praiseworthiness in domains other than the moral. For example, we often praise people for their aesthetic and epistemic achievements and blame them for their failures. On the other hand, it has been argued that there is something special about the moral domain, so that at least one robust kind of responsibility can only be found there. In this paper, I argue that we can adopt (...) a unifying framework for locating responsible agency across domains, thereby capturing and explaining more of our actual practices. The key, I argue, is to identify the right conditions for being morally accountable, which I take to be a matter of having an opportunity of a good enough quality to act well. With this account in hand, I argue that we can adopt a unifying framework that allows us to recognize parallels across domains, even as it points the way to important differences among them. (shrink)
