In this paper I study intentions of the form, that is, intentions with a we-content, and their role in interpersonal coordination. I focus on the notion of epistemic support for such intentions. Using tools from epistemic game theory and epistemic logic, I cast doubt on whether such support guarantees the other agents' conditional mediation in the achievement of such intentions, something that appears important if intentions with a we-content are to count as genuine intentions. I (...) then formulate a stronger version of epistemic support, one that does indeed ensure the required mediation, but I then argue that it rests on excessively strong informational conditions. In view of this I provide an alternative set of conditions that are jointly sufficient for coordination in games, and I argue that these conditions constitute a plausible alternative to the proposed notion of epistemic support.

We show that the contemporary debate surrounding the question “What is the norm of assertion?” presupposes what we call the quantitative view, i.e. the view that this question is best answered by determining how much epistemic support is required to warrant assertion. We consider what Jennifer Lackey ( 2010 ) has called cases of isolated second-hand knowledge and show—beyond what Lackey has suggested herself—that these cases are best understood as ones where a certain type of understanding , rather (...) than knowledge, constitutes the required epistemic credential to warrant assertion. If we are right that understanding (and not just knowledge) is the epistemic norm for a restricted class of assertions, then this straightforwardly undercuts not only the widely supposed quantitative view, but also a more general presupposition concerning the universalisability of some norm governing assertion—the presumption (almost entirely unchallenged since Williamson’s 1996 paper) that any epistemic norm that governs some assertions should govern assertions—as a class of speech act—uniformly.

In this paper I prove that holistic coherentism is logically equivalent to the conjunction of symmetry and quasi-transitivity of epistemic support and a condition on justified beliefs. On the way I defend Tom Stoneham from a criticism made by Darrell Rowbottom and prove a premiss of Stoneham’s argument to be an entailment of coherentism.

I argue that when we use ‘probability’ language in epistemic contexts—e.g., when we ask how probable some hypothesis is, given the evidence available to us—we are talking about degrees of support, rather than degrees of belief. The epistemic probability of A given B is the mind-independent degree to which B supports A, not the degree to which someone with B as their evidence believes A, or the degree to which someone would or should believe A if they (...) had B as their evidence. My central argument is that the degree-of-support interpretation lets us better model good reasoning in certain cases involving old evidence. Degree-of-belief interpretations make the wrong predictions not only about whether old evidence confirms new hypotheses, but about the values of the probabilities that enter into Bayes’ Theorem when we calculate the probability of hypotheses conditional on old evidence and new background information.

Although there is increasing recognition that theory and practice in science are often inseparably intertwined, discussions of scientific controversies often continue to focus on theory, and not practice or methodologies. As a contribution to constructing a framework towards understanding controversies linked to scientific practices, we introduce the notion of borrowed epistemic credibility, to describe the situation in which scientists exploit fallacious similarities between accepted tenets in other fields to garner support for a given position in their own field. (...) Our proposal is based on the analysis of a recent controversy in phylogeography, a biological subdiscipline concerned with the study of the historical causes of variation in genetic diversity within species in concrete biogeographical locations. Through a review of the arguments that support the two conflicting phylogeographic schools, we show that ‘theory’ plays essentially no role as a foundation of the controversy, whereas both sides borrow epistemic credibility from sources such as formal logic, similarity of results to those in other scientific areas, the authority of prominent scientists, or the presumed superiority of quantitative vs. verbal reasoning. Our case study underscores the indivisibility of theory and practice and provide a means to re-examine important philosophical issues such as the meaning of inference, rationality, justification, and objectivity in scientific practice.

Recently, more attention has been paid to the nature and value of the intellectual virtue of epistemic autonomy. One underexplored issue concerns how epistemic autonomy is related to other intellectual virtues. Plausibly, epistemic autonomy is closely related to a number of intellectual virtues like curiosity, inquisitiveness, intellectual perseverance, and intellectual courage to name just a few. Here, however, I will examine the relation between epistemic autonomy and intellectual humility. I will argue that epistemic autonomy and (...) intellectual humility bear an interesting relationship to one another in that they are interconnected and mutually supporting intellectual virtues. In sections 2 and 3 I will provide a brief overview of the predominant accounts of intellectual humility (section 2) and epistemic autonomy (section 3) in the literature. With an understanding of these intellectual virtues in hand, we will examine their relationship of mutual support in section 4. Section 5 will explore a challenge to this relationship coming from the epistemology of disagreement, and section 6 concludes. (shrink)

Despite the importance of discussions over the epistemic role that artificially intelligent decision support systems ought to play, there is currently a lack of these discussions in both the AI literature and the epistemology literature. My goal in this paper is to rectify this by proposing an account of the epistemic role of AI decision support systems in medicine and discussing what this epistemic role means with regard to how these systems ought to be utilized. (...) In particular, I argue that AI decision support systems are not epistemic superiors, inferiors, or peers. Instead, I recommend that they be classified in an epistemic category of their own, as “epistemic nudges.” With my proposed account of the epistemic role of AI decision support systems, I aim to provide answers the following two questions: 1. How ought disagreements between a clinician and an AI decision support system be handled? 2. How ought responsibility and accountability be allocated when an AI decision support system used by a human clinician in decision-making results in harm? (shrink)

I focus on the No-Paradise Dilemma, which results from some initially plausible epistemic ideals, coupled with an assumption concerning our evidence. Our evidence indicates that we are not in an epistemic paradise, in which we do not experience cognitive failures. I opt for a resolution of the dilemma that is based on an evidentialist position that can be motivated independently of the dilemma. According to this position, it is rational for an agent to believe a proposition on the (...) agent’s total evidence just in case the (total) evidence stably supports the proposition. Based on this evidentialist position, I argue that it is not an epistemic ideal in the actual world that we hold rational beliefs that are logically equivalent to our rational beliefs. The dilemma is resolved by giving up this ideal for the actual world and adopting the evidentialist position in terms of stable evidential support. (shrink)

In his topical article, Andrew Cling claims that the best extant formulation of the so-called epistemic regress problem rests on five assumptions that are too strong. Cling offers an improved version that rests on a different set of three core epistemic assumptions, each of which he argues for. Despite of owing a great deal to Cling’s ideas, I argue that the epistemic regress problem surfaces from more fundamental assumptions than those offered by Cling. There are ultimately two (...) core assumptions—in fact two contradictory strands within the concept of epistemic support—which jointly create a powerful challenge for our pursuit of paramount epistemic values.

How can we assess the epistemic quality of democratic decision-making? Sceptics doubt such assessments are possible, as they must rely on controversial substantive standards of truth and rightness. Challenging that scepticism, this paper suggests a procedure-independent standard for assessing the epistemic quality of democratic decision-making by evaluating whether it is adequately supported by reasons. Adequate support for conclusion is a necessary aspect of epistemic quality for any epistemic justification of democracy, though particularly relevant to theories (...) that emphasize public deliberation. Finding existing methods for measuring the quality of public discourse to fall short, we draw on an epistemological theory of argumentation to provide a more sophisticated approach to evaluating the epistemic quality of democratic decision-making, illustrate how the approach can be used, and demonstrate its relevance for the epistemic turn in democratic theory.

Evidentialism is a popular theory of epistemic justification, yet, as early proponents of the theory Earl Conee and Richard Feldman admit, there are many elements that must be developed before Evidentialism can provide a full account of epistemic justification, or well-founded belief. It is the aim of this book to provide the details that are lacking; here McCain moves past Evidentialism as a mere schema by putting forward and defending a full-fledged theory of epistemic justification. In this (...) book McCain offers novel approaches to several elements of well-founded belief. Key among these are an original account of what it takes to have information as evidence, an account of epistemic support in terms of explanation, and a causal account of the basing relation that is far superior to previous accounts. The result is a fully developed Evidentialist account of well-founded belief. (shrink)

A particular belief of a person is basic just in case it is epistemically justified and it owes its justification to something other than her other beliefs or the interrelations of their contents; a person’s belief is nonbasic just in case it is epistemically justified but not basic. Traditional Foundationalism says that, first, if a human being has a nonbasic belief, then, at bottom, it owes its justification to at least one basic belief, and second, there are basic beliefs. Call (...) the second thesis Minimal Foundationalism. In this essay, we assess three arguments against Minimal Foundationalism which we find in recent work of Peter Klein and Ernest Sosa. (shrink)

Many people, such as Adam Smith, Milton Friedman, Irving Fisher, and William Sharpe, assume that free markets full of rational people automatically lead to ethical actions and outcomes. After all, at its equilibrium point, a perfectly competitive free market maximizes utility, respects autonomy, and fulfills justice’s dictates. Unfortunately, in some technology markets, there are a significant number of people who have undergone epistemic closure. Epistemic closure entails that all reliable evidence that would challenge deeply held beliefs is dismissed (...) as corrupted, whereas all supporting evidence, no matter how unreliable, is accepted as incontrovertible. Those who have the condition act irrationally within that domain. As a result, business decisions become much more difficult than they would be in a rational market. In this article, epistemic closure’s ethical issues are developed. First, although they are acting irrationally within the closure’s domain, those with epistemic closure can still be held accountable for their actions. Second, to deal ethically with epistemic closure and its consequences, then it is vital to know what it is and its root causes, as well as to have a practical principle that can assist in making pragmatic decisions. Because some new technologies face epistemic closure, then focusing on a particular representative case of it will help to illustrate the issue’s ethical dimensions. (shrink)

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically (...) rational in the sense that both are supported by sufficient evidence.

Background Given that AI-driven decision support systems (AI-DSS) are intended to assist in medical decision making, it is essential that clinicians are willing to incorporate AI-DSS into their practice. This study takes as a case study the use of AI-driven cardiotography (CTG), a type of AI-DSS, in the context of intrapartum care. Focusing on the perspectives of obstetricians and midwives regarding the ethical and trust-related issues of incorporating AI-driven tools in their practice, this paper explores the conditions that AI-driven (...) CTG must fulfill for clinicians to feel justified in incorporating this assistive technology into their decision-making processes regarding interventions in labor. Methods This study is based on semi-structured interviews conducted online with eight obstetricians and five midwives based in England. Participants were asked about their current decision-making processes about when to intervene in labor, how AI-driven CTG might enhance or disrupt this process, and what it would take for them to trust this kind of technology. Interviews were transcribed verbatim and analyzed with thematic analysis. NVivo software was used to organize thematic codes that recurred in interviews to identify the issues that mattered most to participants. Topics and themes that were repeated across interviews were identified to form the basis of the analysis and conclusions of this paper. Results There were four major themes that emerged from our interviews with obstetricians and midwives regarding the conditions that AI-driven CTG must fulfill: (1) the importance of accurate and efficient risk assessments; (2) the capacity for personalization and individualized medicine; (3) the lack of significance regarding the type of institution that develops technology; and (4) the need for transparency in the development process. Conclusions Accuracy, efficiency, personalization abilities, transparency, and clear evidence that it can improve outcomes are conditions that clinicians deem necessary for AI-DSS to meet in order to be considered reliable and therefore worthy of being incorporated into the decision-making process. Importantly, healthcare professionals considered themselves as the epistemic authorities in the clinical context and the bearers of responsibility for delivering appropriate care. Therefore, what mattered to them was being able to evaluate the reliability of AI-DSS on their own terms, and have confidence in implementing them in their practice. (shrink)

Many views rely on the idea that it can never be rational to have high confidence in something like, “P, but my evidence doesn’t support P.” Call this idea the “Non-Akrasia Constraint”. Just as an akratic agent acts in a way she believes she ought not act, an epistemically akratic agent believes something that she believes is unsupported by her evidence. The Non-Akrasia Constraint says that ideally rational agents will never be epistemically akratic. In a number of recent papers, (...) the Non-Akrasia Constraint has been called into question. The goal of this paper is to defend it... for the most part. (shrink)

Support is canvassed for a novel solution to the sceptical problem regarding our knowledge of the external world. Key to this solution is the claim that what initially looks like a single problem is in fact two logically distinct problems. In particular, there are two putative sceptical paradoxes in play here, which each trade on distinctive epistemological theses. It is argued that the ideal solution to radical scepticism would thus be a biscopic proposal—viz., a two-pronged, integrated, undercutting treatment of (...) both putative sceptical paradoxes. A particular biscopic proposal is then explored which brings together two apparently opposing anti-sceptical theses: he Wittgensteinian account of the structure of rational evaluation and epistemological disjunctivism. It is argued that each proposal enables us to gain a purchase on one, but only one, aspect of the two-sided sceptical problem. Furthermore, it is argued that these proposals are not only compatible positions, but also mutually supporting and advanced in the same undercutting spirit. A potential cure is thus offered for epistemic angst. (shrink)

Moderate epistemic akrasia is the state a subject is in when she believes that p and suspends judgment about whether her evidence supports p. In this article it is argued that, given a certain understanding of the attitude of suspension of judgment, moderate epistemic akrasia is doxastically irrational. The paper starts with a brief introduction that makes explicit some background notions and clarifies the dialectics of the debate. Second, the well-known distinction between propositional and doxastic rationality is introduced (...) and some cases of improper basing are discussed. Third, two different cases are considered in which one might argue that moderate epistemic akrasia is doxastically rational, and it is argued that none is successful. Fourth, several objections are presented and answered. Finally, some conclusions are drawn. (shrink)

I argue that scientific knowledge is collective knowledge, in a sense to be specified and defended. I first consider some existing proposals for construing collective knowledge and argue that they are unsatisfactory, at least for scientific knowledge as we encounter it in actual scientific practice. Then I introduce an alternative conception of collective knowledge, on which knowledge is collective if there is a strong form of mutual epistemic dependence among scientists, which makes it so that satisfaction of the justification (...) condition on knowledge ineliminably requires a collective. Next, I show how features of contemporary science support the conclusion that scientific knowledge is collective knowledge in this sense. Finally, I consider implications of my proposal and defend it against objections. (shrink)

It has often been noticed that conciliatory views of disagreement are "self-undermining" in a certain way: advocates of such views cannot consistently maintain them when other philosophers disagree. This leads to apparent problems of instability and even inconsistency. Does self-undermining, then, show conciliationism untenable? If so, the untenablity would extend not only to almost all views of disagreement, but to a wide range of other views supporting what one might call epistemic modesty: roughly, the idea that getting evidence that (...) one has made an epistemic error in arriving at one’s opinion may require adjusting that opinion. This paper argues that the phenomenon of self-undermining does not disclose any defect in views mandating epistemic modesty. Instead, it highlights an uncomfortable but natural consequence of reflecting on one's own possible epistemic imperfections, a sort of reflection that tends to cause epistemic ideals to conflict.

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)

We live in a world in which scientific expertise and its epistemic authority become more important. On the other hand, the financial interests in research, which could potentially corrupt science, are increasing. Due to these two tendencies, a concern for the integrity of scientific research becomes increasingly vital. This concern is, however, hollow if we do not have a clear account of research integrity. Therefore, it is important that we explicate this concept. Following Rudolf Carnap’s characterization of the task (...) of explication, this means that we should develop a concept that is (1) similar to our common sense notion of research integrity, (2) exact, (3) fruitful, and (4) as simple as possible. Since existing concepts do not meet these four requirements, we develop a new concept in this article. We describe a concept of epistemic integrity that is based on the property of deceptiveness, and argue that this concept does meet Carnap’s four requirements of explication. To illustrate and support our claims we use several examples from scientific practice, mainly from biomedical research. (shrink)

There are important similarities between the epistemic regress problem and the problem of the criterion. Each turns on plausible principles stating that epistemic reasons must be supported by epistemic reasons but that having reasons is impossible if that requires having endless regresses of reasons. These principles are incompatible with the possibility of reasons, so each problem is a paradox. Whether there can be an antiskeptical solution to these paradoxes depends upon the kinds of reasons that we need (...) in order to attain our epistemic goals. This article explains the problems and considers the ways in which two different conceptions of human flourishing support the value of different kinds of reasons. One conception requires reasons that allow an easy solution to these paradoxes. The other—rational autonomy—requires reasons that depend upon endless regresses. So we cannot have the kinds of fully transparent reasons required for rational autonomy. (shrink)

The author describes a formal system for interpreting and generating epistemically-qualified judgments, that is, judgments qualified by phrases like “it is certain that,” “it is almost certain that,” “it is plausible that,” and “it is doubtful that.” The system has two noteworthy properties. First, the system’s qualifiers are purely qualitative. Second, the system is based on epistemic warranting conditions, not truth conditions. The first property is noteworthy because it makes the system an alternative to systems that use numerical certainty (...) factors to interpret epistemic qualifiers; unlike these numerically-based systems, the system the author describes is faithful to the surface meanings of epistemic qualifiers. The second property is noteworthy because it makes the system an altemative to deductive systems; unlike deductive systems, the system the author describes supports nonmonotonic inferences. The author’s account includes precise warranting conditions for system-supported judgments, a semantics that fixes the meaning of system judgments, and algorithms for generating system judgments.

[ Alan W. Richardson] This essay explores the uses that Michael Friedman and Bas van Fraassen have recently made of the work of Hans Reichenbach. It uses Friedman's work to complicate van Fraassen's invocation of Reichenbach's voluntarism in support of empiricism.

We are, finally, left with questions about the status and content of the account of the epistemic subject available to an epistemological voluntarist. (...) /// [Thomas E. Uebel] This response considers the question whether empiricists are condemned to silence about the epistemic agency their theories attribute or presuppose. It is argued that, unlike Reichenbach or Carnap, Neurath allowed for and indeed provided specifications of the role of epistemic agency in scientific inquiry. If this is correct, it underscores once more the need to distinguish between the various strands of logical positivism which show different strengths and weaknesses. (shrink)

It has been suggested, by Michael Bishop, that empirical evidence on human reasoning poses a threat to the internalist account of epistemic responsibility, which he takes to associate being epistemically responsible with coherence, evidence-fitting and reasons-responsiveness. Bishop claims that the empirical data challenges the importance of meeting these criteria by emphasising how it is possible to obtain true beliefs by diverging from them. He suggests that the internalist conception of responsibility should be replaced by one that properly reflects how (...) we can reliably obtain true beliefs. In this paper I defend the internalist account by arguing that Bishop has misinterpreted the relevance of the empirical evidence to the philosophical theory. I argue that the empirical data actually provides support for the idea that, if we want to obtain true beliefs by being responsible, we should aim to meet the criteria that internalists associate with epistemic responsibility.

We discuss the scientific task of historical reconstruction and the problem of epistemic access. We argue that strong epistemic support for historical claims consists in the consilience of multiple independent lines of evidence, and analyze the impact hypothesis for the End-Cretaceous mass extinction to illustrate the accrual of epistemic support. Although there are elements of the impact hypothesis that enjoy strong epistemic support, the general conditions for this are strict, and help to clarify (...) the difficulties associated with reconstructing the deep past.

There are a number of debates that are relevant to questions concerning objectivity in science. One of the eldest, and still one of the most intensely fought, is the debate over epistemic relativism. —All forms of epistemic relativism commit themselves to the view that it is impossible to show in a neutral, non-question-begging, way that one “epistemic system”, that is, one interconnected set of epistemic standards, is epistemically superior to others. I shall call this view “No-metajustification”. (...) No-metajustification is commonly taken to deny the objectivity of standards. In this paper I shall discuss two currently popular attempts to attack “No-metajustification”. The first attempt attacks no-metajustification by challenging a particular strategy of arguing in its defence: this strategy involves the ancient Pyrrhonian “Problem of the Criterion”. The second attempt to refute No-metajustification targets its metaphysical underpinning: to wit, the claim that there are, or could be, several fundamentally different and irreconcilable epistemic systems. I shall call this assumption “Pluralism”. I shall address three questions with respect to these attempts to refute epistemic relativism by attacking no-metajustification: Can the epistemic relativist rely on the Problem of the Criterion in support of No-metajustification? Is a combination of Chisholmian “particularism” and epistemic naturalism an effective weapon against No-metajustification? And is Pluralism a defensible assumption? (shrink)

Epistemic Angst offers a completely new solution to the ancient philosophical problem of radical skepticism—the challenge of explaining how it is possible to have knowledge of a world external to us. Duncan Pritchard argues that the key to resolving this puzzle is to realize that it is composed of two logically distinct problems, each requiring its own solution. He then puts forward solutions to both problems. To that end, he offers a new reading of Wittgenstein's account of the structure (...) of rational evaluation and demonstrates how this provides an elegant solution to one aspect of the skeptical problem. Pritchard also revisits the epistemological disjunctivist proposal that he developed in previous work and shows how it can effectively handle the other aspect of the problem. Finally, he argues that these two antiskeptical positions, while superficially in tension with each other, are not only compatible but also mutually supporting. The result is a comprehensive and distinctive resolution to the problem of radical skepticism, one that challenges many assumptions in contemporary epistemology. (shrink)

Philosophers generally assume that “contextual” factors blunt the force of “external world” skepticism. I argue herein that this is not the case. On the contrary, properly invoked contextual considerations support, rather than undermine, the skeptic's agenda. This is because the contexts of assessment against which we rightfully judge that knowledge is or is not available ultimately consist in little more than our own presuppositions concerning the objectivity of the items at issue. What this implies, given the mind-independence of the (...) external world, is the aptness of apodictic epistemic standards, and skepticism itself in the process. (shrink)

“Epistemic Dexterity: A Ramseyian Account of Epistemic Virtue” by Abrol Fairweather & Carlos Montemayor: A modification of F.P. Ramsey’s success semantics supports a naturalized theory of epistemic virtue that includes motivational components and can potentially explain both epistemic reliability and responsibility with a single normative-explanatory principle. An “epistemic Ramsey success” will also provide a better account of the “because of” condition central to virtue-reliabilist accounts of knowledge from Greco, Sosa and Pritchard. Ramsey said that the (...) truth condition of a belief is the condition that guarantees the success of desires based on that belief. Taken as a theory of epistemic achievements, the truth condition for the attribution of an epistemic achievement is the condition that guarantees the success of epistemic desires and is also a success based on abilities attributable to the agent. One of its major advantages is that it may be the best way to achieve a naturalistic version of the etiologcal requirement on knowledge in virtue epistemology while also supporting important responsibilist desiderata. The account defended is robustly agent-centered in the straightforward sense that individual desires are partly constitutive of epistemic successes like having a rational belief, justified belief, and even of knowledge once we see the both the reliabilist and repsonsibilist desiderata are met. Another important aspect of the paper is that it provides a plausible psychology for virtue epistemology that is grounded in important empirical findings on agency, and thus constitutes a form of naturalized virtue epistemology.

Recently, a number of theorists (MacFarlane (2003, 2011), Egan et al. (2005), Egan (2007), Stephenson (2007a,b)) have argued that an adequate semantics and pragmatics for epistemic modals calls for some technical notion of relativist truth and/or relativist content. Much of this work has relied on an empirical thesis about speaker judgments, namely that competent speakers tend to judge a present-tense bare epistemic possibility claim true only if the prejacent is compatible with their information. Relativists have in particular appealed (...) to judgments elicited in so-called eavesdropping and retraction cases to support this empirical thesis. But opposing theorists have denied the judgments, and at present there is no consensus in the literature about how the speaker judgments in fact pattern. Consequently there is little agreement on what exactly a semantics and pragmatics for epistemic modals should predict about the pattern of judgments in these cases. Further theorizing requires greater clarity on the data to be explained. To clarify the data, we subjected eavesdropping and retraction cases to experimental evaluation. Our data provide evidence against the claim that competent speakers tend to judge a present-tense bare epistemic possibility claim true only if the prejacent is compatible with their information. Theories designed to predict this result are accordingly undermined. (shrink)

Sometimes it is epistemically beneficial to form a belief on authority. When you do, what happens to other reasons you have for that belief? Linda Zagzebski’s total-preemption view says that these reasons are “preempted”: you still have them, but you do not use them to support your belief. I argue that this situation is problematic, because having reasons for a belief while not using them forfeits you doxastic justification. I present an alternative account of belief on authority, the proper-basing (...) view, which enables the agent to base her belief on as many reasons as she has. A salient result is that the notion of a preemptive reason, useful though it may be in accounting for acting on authority, does not have any place in an account of believing on authority or in epistemology more generally.

Recent critics of Sellars's argument against the Given attack Sellars's conclusion that sensations cannot play a role in the justification of observation beliefs. I maintain that Sellars can concede that sensations play a role in justifying observation reports without being forced to concede that they have the foundational status of an epistemic Given. However, Sellars's own arguments that observation reports rest, in some sense, on other empirical beliefs are not sufficiently well-developed; nor are his comments concerning internalism, which is (...) crucial to his attack on the Given. As a result, both of these aspects of Sellars's epistemology have been attacked, and their significance has gone unrecognized by many philosophers. In this paper, I will try to fill in some of the missing pieces, so that we can see that not only are Sellars's theses concerning internalism and epistemic priority correct, but they represent a devastating attack on the Given, even if Sellars concedes that sensation can play a role in justifying observation beliefs. In short, we will see that these recent arguments in support of the Given have not succeeded in reviving it. The Given remains a myth. (shrink)

According to a widely held view, epistemic reasons are normative reasons for belief – much like prudential or moral reasons are normative reasons for action. In recent years, however, an increasing number of authors have questioned the assumption that epistemic reasons are normative. In this article, I discuss an important challenge for anti-normativism about epistemic reasons and present a number of arguments in support of normativism. The challenge for anti-normativism is to say what kind of reasons (...) epistemic reasons are if they are not normative reasons. I discuss various answers to this challenge and find them all wanting. The arguments for normativism each stress a certain analogy between epistemic reasons and normative reasons for action. Just like normative reasons for action, epistemic reasons provide partial justification; they provide premises for correct reasoning; they constitute good bases for the responses they are reasons for; and they are reasons for which agents can show these responses without committing a mistake. In each case, I argue that the relevant condition is plausibly sufficient for the normativity of a reason, and that normativism is in any case in a much better position to explain the analogy than anti-normativism.

Epistemic contextualism is the theory that “knows” is a context sensitive expression. As a linguistic theory, epistemic contextualism is motivated by claims about the linguistic behavior of competent speakers. This chapter reviews evidence in experimental cognitive science for epistemic contextualism in linguistic behavior. This research demonstrates that although some observations that are consistent with epistemic contextualism can be confirmed in linguistic practices, these observations are also equally well explained both by psychological features that do not provide (...) support for contextualism and by rival theories that are inconsistent with contextualism. I conclude that the motivation for epistemic contextualism is underdetermined by existing experimental evidence, yielding little reason to accept it as an account of our actual linguistic practices.

This study investigates the epistemic role and value of prediction in science: do predictions, and what kind of predictions, justify belief in scientific theories? In the philosophy of science, the epistemic role of prediction has been understood mainly in terms of novel prediction. Scientific theories are considered to gain special epistemic support if they predict novel empirical results that were not used in their construction. This view has played a central role in two debates in the (...) field: prediction vs. accommodation and scientific realism vs. anti-realism. In the former debate, predictivists seek to explain why novel predictions confirm the theory more strongly than accommodations, i.e. empirical results that were used in the construction of the theory. In the latter debate, predictivists argue that novel prediction is one of the most important criteria of empirical success that justifies realist commitment to scientific theories. -/- . (shrink)

The field of epistemic logic developed into an interdisciplinary area focused on explicating epistemic issues in, for example, artificial intelligence, computer security, game theory, economics, multiagent systems and the social sciences.

More in details, I introduce a structure S to syntactically and semantically modelling metadata extracted with systems for extracting structured (...) metadata from scientific articles in a born-digital form. These systems will be considered, in the logical model created, as ‘Metadata extraction agents’. In this case MEA taken into consideration are CERMINE and TeamBeam. In an increasingly data-driven world, modelling data or metadata means to help systematise existing information and support the research community in building solutions to the COVID-19 pandemic.

Dynamic Epistemic Logic is the logic of knowledge change. This book provides various logics to support such formal specifications, including proof systems. Concrete examples and epistemic puzzles enliven the exposition. The book also offers exercises with answers. It is suitable for graduate courses in logic. Many examples, exercises, and thorough completeness proofs and expressivity results are included. A companion web page offers slides for lecturers and exams for further practice.

Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.

Our intuitions about what a person epistemically ought or ought not believe are sometimes quite clear. Keith DeRose and Richard Feldman have devised examples about which our intuitions are likely to conflict. DeRose argues that the conflict of intuitions arises from ambiguity in the epistemic ought. I argue that it results from incompleteness. The success of the argument depends on rejecting the narrow conception of evidential support according to which a person’s evidence supports some proposition P only if (...) the person apprehends the connection between her evidence and P. I argue that this view is mistaken. (shrink)
