The recent discussion on scientific representation has focused on models and their relationship to the real world. It has been assumed that models give us knowledge because they represent their supposed real target systems. However, here agreement among philosophers of science has tended to end as they have presented widely different views on how representation should be understood. I will argue that the traditional representational approach is too limiting as regards the epistemic value of modelling given the focus on (...) the relationship between a single model and its supposed target system, and the neglect of the actual representational means with which scientists construct models. I therefore suggest an alternative account of models as epistemictools. This amounts to regarding them as concrete artefacts that are built by specific representational means and are constrained by their design in such a way that they facilitate the study of certain scientific questions, and learning from them by means of construction and manipulation.

Simulation as an epistemic tool between theory and practice: A Comparison of the Relationship between Theory and Simulation in Science and in Folk Psychology In this paper I explore the concept of simulation that is employed by proponents of the so-called simulation theory within the debate about the nature and scientific status of folk psychology. According to simulation theory, folk psychology is not a sort of theory that postulates theoretical entities (mental states and processes) and general laws, but a (...) practice whereby we put ourselves into others’ shoes and simulate their situation from our own perspective. On the basis of this sort of simulation, we supposedly know how we would act or think or feel, and then expect the same of others. A closer look at the concept of simulation reveals some problems with this view, but also helps to clarify the insight motivating simulation theory. Specifically, I defend the thesis that the analogy to simulations in science shows us how theoretical elements in folk psychology can be complemented by (i.e. not replaced by) the central idea of simulation theory – namely that our own cognitive habits and dispositions provide us with a resource that is distinct from propositional knowledge in folk psychology. I also discuss the idea that our use of simulations during cognitive development enables us to imitate the people around us and thereby to become more similar to them, which in turn makes simulation an increasingly effective epistemic strategy. Insofar as theoretical elements – such as the distinctions, relations, and entities referred to in folk psychological discourse – play a role in imitative learning, they are causally embedded in our cognitive development, so we have good reason to regard them as being among the real causes of our behavior.

This article develops a social epistemological analysis of Web-based search engines, addressing the following questions. First, what epistemic functions do search engines perform? Second, what dimensions of assessment are appropriate for the epistemic evaluation of search engines? Third, how well do current search engines perform on these? The article explains why they fulfil the role of a surrogate expert, and proposes three ways of assessing their utility as an epistemic tool—timeliness, authority prioritisation, and objectivity. “Personalisation” is a (...) current trend in Internet-delivered services, and consists in tailoring online content to the interests of the individual user. It is argued here that personalisation threatens the objectivity of search results. Objectivity is a public good; so there is a prima facie case for government regulation of search engines. (shrink)
Epistemic expressivism is the application of a nexus of ideas, which is prominent in ethical theory (more specifically, metaethics), to parallel issues in epistemological theory (more specifically, metaepistemology). Here, in order to help those new to the debate come to grips with epistemic expressivism and recent discussions of it, I first briefly present this nexus of ideas as it occurs in ethical expressivism. Then, I explain why and how some philosophers have sought to extend it to a version (...) of epistemic expressivism. Finally, I consider a number of objections and replies with the aim of giving the reader the tools needed to begin to evaluate the promise and prospects of epistemic expressivism. (shrink)
My goal in this paper is to generalize Kirsh and Maglio’s (1994) distinction between pragmatic and epistemic actions from the level of individuals to the level of groups. I use the concept of a collective epistemic action to refer to the ways in which groups of people actively change the structure of their social organization, with the epistemic goal of reshaping and augmenting their cognitive performance as integrated collectivities. By placing a renewed emphasis on the interactions between (...) people, rather than between people and their tools I hope to reconnect the cognitive-scientifically-driven “extended mind” thesis (Clark and Chalmers 1998; Clark 2008) with complementary areas of social-scientific research in which groups are analyzed as the seats of action and cognition in their own right. In particular, the literature to which I aim to build a bridge in this paper are certain segments of social and organizational psychology on the one hand (Larsen and Christensen 1993; Hinsz et al. 1997, Mohammed and Dumville 2001), and theories of collective and institutional action on the other hand (Ostrom 1990, List and Pettit 2011).

I distinguish between two senses in which feminists have argued that the knower is social: 1. situated or socially positioned and 2. interdependent. I argue that these two aspects of the knower work in cooperation with each other in a way that can produce willful hermeneutical ignorance, a type of epistemic injustice absent from Miranda Fricker's Epistemic Injustice. Analyzing the limitations of Fricker's analysis of the trial of Tom Robinson in Harper Lee's To Kill a Mockingbird with attention (...) to the way in which situatedness and interdependence work in tandem, I develop an understanding of willful hermeneutical ignorance, which occurs when dominantly situated knowers refuse to acknowledge epistemictools developed from the experienced world of those situated marginally. Such refusals allow dominantly situated knowers to misunderstand, misinterpret, and/or ignore whole parts of the world. (shrink)
Consider the claim that openmindedness is an epistemic virtue, the claim that true belief is epistemically valuable, and the claim that one epistemically ought to cleave to one’s evidence. These are examples of what I’ll call “epistemic discourse.” In this paper I’ll propose and defend a view called “conventionalism about epistemic discourse.” In particular, I’ll argue that conventionalism is superior to its main rival, expressivism about epistemic discourse. Expressivism and conventionalism both jibe with anti-realism about (...) class='Hi'>epistemic normativity, which is motivated by appeal to philosophical naturalism (§1). Conventionalism says that epistemic discourse describes how things stands relative to a conventional set of “epistemic” values; such discourse is akin to normative discourse relative to the conventional rules of a club (§2). I defend conventionalism by appeal to a “reverse open question argument,” which says, pace expressivism, that epistemic discourse leaves the relevant normative questions open (§3). (shrink)
What are the consequences of evolutionary theory for the epistemic standing of our beliefs? Evolutionary considerations can be used to either justify or debunk a variety of beliefs. This paper argues that evolutionary approaches to human cognition must at least allow for approximately reliable cognitive capacities. Approaches that portray human cognition as so deeply biased and deficient that no knowledge is possible are internally incoherent and self-defeating. As evolutionary theory offers the current best hope for a naturalistic epistemology, evolutionary (...) approaches to epistemic justification seem to be committed to the view that our sensory systems and belief-formation processes are at least approximately accurate. However, for that reason they are vulnerable to the charge of circularity, and their success seems to be limited to commonsense beliefs. This paper offers an extension of evolutionary arguments by considering the use of external media in human cognitive processes: we suggest that the way humans supplement their evolved cognitive capacities with external tools may provide an effective way to increase the reliability of their beliefs and to counter evolved cognitive biases.

The presence of luck in our cognitive as in our moral lives shows that the quality of our intellectual character may not be entirely up to us as individuals, and that our motivation and even our ability to desire the truth, like our moral goodness, can be fragile. This paper uses epistemologists'responses to the problem of “epistemic luck” as a sounding board and locates the source of some of their deepest disagreements in divergent, value-charged “interests in explanation,” which epistemologists (...) bring with them to discussions of knowledge and justification. In so doing, I delineate both the commonalities and key differences between those authors I describe as virtue reliabilists and those I describe as virtue responsibilists. (shrink)
I argue that scientific explanation has a pragmatic dimension that is epistemically relevant. Philosophers with an objectivist approach to scientific explanation (e.g. Hempel, Trout) hold that the pragmatic aspects of explanation do not have any epistemic import. I argue against this view by focusing on the role of models in scientific explanation. Applying recent accounts of modelling (Cartwright, Morgan and Morrison) to a case-study of nineteenth-century physics, I analyse the pragmatic dimension of the process of model construction. I highlight (...) the crucial roles that conceptual tools, skills, and commitments play in this dimension, and show how they contribute to the epistemic aim of science. (shrink)
This article argues that understanding everyday practices in neurobiological labs requires us to take into account a variety of different action positions: self-conscious social actors, technical artifacts, conscious organisms, and organisms being merely alive. In order to understand the interactions among such diverse entities, highly differentiated conceptual tools are required. Drawing on the theory of the German philosopher and sociologist Helmuth Plessner, the paper analyzes experimenters as self-conscious social persons who recognize monkeys as conscious organisms. Integrating Plessner’s ideas into (...) the stock of concepts used in science and technology studies provides richer descriptions of laboratory life. In particular, this theory allows an understanding of a crucial feature of neurobiological brain research: the construction of the brain as the epistemic object of brain research. As such, the brain must be isolated from the acting and interacting organism in a complicated process. (shrink)
This paper addresses the problem posed by the current split between the two opposed hypotheses in the growing literature on the fallacy of begging the question the epistemic hypothesis, based on knowledge and belief, and the dialectical one, based on formal dialogue systems. In the first section, the nature of split is explained, and it is shown how each hypothesis has developed. To get the beginning reader up to speed in the literature, a number of key problematic examples are (...) analyzed illustrating how both approaches can be applied. Useful tools are brought to bear on them, including the automated argument diagramming system Araucaria, and profiles of dialogue used to represent circular argumentation in a dialogue tableau format. These tools are used to both to model circular reasoning and to provide the contextual evidence needed to properly determine whether the circular reasoning in a given case is better judged fallacious or not. A number of technical problems that have impeded the development of both hypotheses are studied. One central problem is the distinction between argument and explanation. It is concluded that the best way to move forward and solve these problems is to reformulate the two hypotheses in such a way that they might be able to co-exist. On this basis, a unified methodology is proposed that allows each hypothesis to move forward as a legitimate avenue for research using the same tools. (shrink)
Branching-time temporal logics have proved to be an extraordinarily successful tool in the formal specification and verification of distributed systems. Much of their success stems from the tractability of the model checking problem for the branching time logic CTL, which has made it possible to implement tools that allow designers to automatically verify that systems satisfy requirements expressed in CTL. Recently, CTL was generalised by Alur, Henzinger, and Kupferman in a logic known as Alternating-time Temporal Logic (ATL). The key (...) insight in ATL is that the path quantifiers of CTL could be replaced by cooperation modalities, of the form , where is a set of agents. The intended interpretation of an ATL formula is that the agents can cooperate to ensure that holds (equivalently, that have a winning strategy for ). In this paper, we extend ATL with knowledge modalities, of the kind made popular in the work of Fagin, Halpern, Moses, Vardi and colleagues. Combining these knowledge modalities with ATL, it becomes possible to express such properties as group can cooperate to bring about iff it is common knowledge in that . The resulting logic — Alternating-time Temporal Epistemic Logic (ATEL) — shares the tractability of model checking with its ATL parent, and is a succinct and expressive language for reasoning about game-like multiagent systems.

This volume brings historians of science and social historians together to consider the role of "little tools"--such as tables, reports, questionnaires, dossiers, index cards--in establishing academic and bureaucratic claims to authority and objectivity. From at least the eighteenth century onward, our science and society have been planned, surveyed, examined, and judged according to particular techniques of collecting and storing knowledge. Recently, the seemingly self-evident nature of these mundane epistemic and administrative tools, as well as the prose in (...) which they are cast, has demanded historical examination. The essays gathered here, arranged in chronological order by subject from the late seventeenth to the late twentieth century, involve close readings of primary texts and analyses of academic and bureaucratic practices as parts of material culture. The first few essays, on the early modern period, largely point to the existence of a "juridico-theological" framework for establishing authority. Later essays demonstrate the eclipse of the role of authority per se in the modern period and the emergence of the notion of "objectivity." Most of the essays here concern the German cultural space as among the best exemplars of the academic and bureaucratic practices described above. The introduction to the volume, however, is framed at a general level the closing essays also extend the analyses beyond Germany to broader considerations on authority and objectivity in historical practice. The volume will interest scholars of European history and German studies as well as historians of science. Peter Becker is Professor of Central European History, European University Institute.

Philosophers have usually offered a number of ways of describing hypotheses generation, but all aim at demonstrating that the activity of generating hypotheses is paradoxical, illusory or obscure, and then not analysable. Those descriptions are often so far from Peircian pragmatic prescription and so abstract to result completely unknowable and obscure. The computational turn gives us a new way to understand creative processes in a strictly pragmatic sense. In fact, by exploiting artificial intelligence and cognitive science tools, computational philosophy (...) allows us to test concepts and ideas previously conceived only in abstract terms. It is in the perspective of these actual computational models that I find the central role of abduction in the explanation of creative reasoning in science. Creativity and discovery are no more seen as a mysterious irrational process, but, thanks to constructive accounts, as a complex relationship among different inferential steps that can be clearly analysed and identified. I maintain that the computational philosophy analysis of model-based and manipulative abduction and of external and epistemic mediators is important not only to delineate the actual practice of abduction, but also to further enhance the development of programs computationally adequate in rediscovering, or discovering for the first time, for example, scientific hypotheses or mathematical theorems.

In this paper, the radical view that transparent equipment is the result of an ecological assembly between tool users and physical aspects of the world is critically assessed. According to this perspective, tool users are normally viewed as plastically organized hybrid agents. In this view, such agents are able to interact with tools (artefacts or technologies) in ways that are opportunistic and fully locked to the local task environment. This intimate and flexible interaction would provide grounds for the thesis (...) that cognitive agents and tools constitute literal extended cognitive systems. By contrast, a revised understanding of tool use transparency will be attempted. In this perspective, the interplay between on-line and off-line thinking is understood in terms of a socially reified cognitive delegation that subsumes the advantages normally associated to the so-called ‘open-ended ecological controllers.’ Thus, the notion of transparent technologies can be explored on the basis of a derived or mediated cognitive delegation. This view will be complemented by the notion of communities of practice (CoP). Special sorts of CoP will be proposed as suitable and flexible cognitive environments for the development of tool transparency. (shrink)

Much of their success stems from the tractability of the model checking problem for the branching time logic CTL, which has made it possible to implement tools that allow designers to automatically verify that systems satisfy requirements expressed in CTL. Recently, CTL was generalised by Alur, Henzinger, and Kupferman in a logic known as "Alternating-time Temporal Logic" (ATL).

The intended interpretation of an ATL formula $\langle \langle \Gamma \rangle \rangle \varphi $ is that the agents Γ can cooperate to ensure that φ holds (equivalently, that Γ have a winning strategy for φ). In this paper, we extend ATL with knowledge modalities, of the kind made popular in the work of Fagin, Halpern, Moses, Vardi and colleagues. Combining these knowledge modalities with ATL, it becomes possible to express such properties as "group Γ can cooperate to bring about φ iff it is common knowledge in Γ that ψ". The resulting logic -- Alternating-time Temporal Epistemic Logic (ATEL) -- shares the tractability of model checking with its ATL parent, and is a succinct and expressive language for reasoning about game-like multiagent systems.

People increasingly form beliefs based on information gained from automatically filtered Internet sources such as search engines. However, the workings of such sources are often opaque, preventing subjects from knowing whether the information provided is biased or incomplete. Users’ reliance on Internet technologies whose modes of operation are concealed from them raises serious concerns about the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns within standard theories of knowledge and justification. (...) To shed light on the problem, we introduce a novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, action, and the technological resources available to a subject. We argue that justified belief is subject to certain epistemic responsibilities that accompany the subject’s particular decision-taking circumstances, and that one typical responsibility is to ascertain, so far as one can, whether the information upon which the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by the inquiry-enabling technologies available to the subject. We argue that a subject’s beliefs that are formed based on Internet-filtered information are less justified than they would be if she either knew how filtering worked or relied on additional sources, and that the subject may have the epistemic responsibility to take measures to enhance the justificatory status of such beliefs..

In this paper I defend a pure proceduralist conception of legitimacy that applies to epistemic democracy. This conception, which I call pure epistemic proceduralism, does not depend on procedure-independent standards for good outcomes and relies on a proceduralist epistemology. It identifies a democratic decision as legitimate if it is the outcome of a process that satisfies certain conditions of political and epistemic fairness. My argument starts with a rejection of instrumentalism – the view that political equality is (...) only instrumentally valuable. I reject instrumentalism on two grounds: (i) because it fails to respect reasonable value pluralism and to recognize the constitutive role of democratic procedures for legitimacy in pluralist societies, and (ii) because it neglects the constructive function of democratic decision-making. I then consider two alternatives to pure epistemic proceduralism: David Estlund's version of epistemic proceduralism and a Deweyan account of epistemic democracy. I argue that only pure epistemic proceduralism can make good on both shortcomings of instrumentalism, whereas each of the other two approaches only makes good on one and neglects the other. (shrink)
Contemporary epistemology of peer disagreement has largely focused on our immediate normative response to prima facie instances of disagreement. Whereas some philosophers demand that we should withhold judgment (or moderate our credences) in such cases, others argue that, unless new evidence becomes available, disagreement at best gives us reason to demote our interlocutor from his peer status. But what makes someone an epistemic peer in the first place? This question has not received the attention it deserves. I begin by (...) surveying different notions of ‘epistemic peer’ that have been peddled in the contemporary literature, arguing that they tend to build normative assumptions about the correct response to disagreement into the notion of peerhood. Instead, I argue, epistemic peerhood needs to be taken seriously in its own right. Importantly, for epistemic agents to count as peers, they should exhibit a comparable degree of reflective awareness of the character and limitations of their own knowledge. (shrink)
In this paper I present a criticism of Sarah Moss‘ recent proposal to use scoring rules as a means of reaching epistemic compromise in disagreements between epistemic peers that have encountered conflict. The problem I have with Moss‘ proposal is twofold. Firstly, it appears to involve a double counting of epistemic value. Secondly, it isn‘t clear whether the notion of epistemic value that Moss appeals to actually involves the type of value that would be acceptable and (...) unproblematic to regard as epistemic.

Abstract Suppose you know that someone is your epistemic peer regarding some topic. You admit that you cannot think of any relevant epistemic advantage you have over her when it comes to that topic; you admit that she is just as likely as you to get P?s truth-value right. Alternatively, you might know that she is your epistemic superior regarding the topic. And then after learning this about her you find out that she disagrees with you about (...) P. In those situations it appears that the confidence with which one holds one?s belief should be significantly reduced. My primary goal in this essay is to present and reflect upon a set of cases of disagreement that have not been discussed in the literature but are vital to consider. I argue that in the new cases one is reasonable in not lowering one?s confidence in the belief. Then I articulate and defend an ambitious principle, the Disagreement Principle, meant to answer the question ?Under what conditions am I epistemically blameworthy in retaining my belief with the same level of confidence after I have discovered recognized peers or superiors who disagree with me??

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)
William Alston’s argument against the deontological conception of epistemic justification is a classic—and much debated—piece of contemporary epistemology. At the heart of Alston’s argument, however, lies a very simple mistake which, surprisingly, appears to have gone unnoticed in the vast literature now devoted to the argument. After having shown why some of the standard responses to Alston’s argument don’t work, we elucidate the mistake and offer a hypothesis as to why it has escaped attention.
This paper contributes to an increasing literature strengthening the connection between epistemic logic and epistemology (Van Benthem, Hendricks). I give a survey of the most important applications of epistemic logic in epistemology. I show how it is used in the history of philosophy (Steiner's reconstruction of Descartes' sceptical argument), in solutions to Moore's paradox (Hintikka), in discussions about the relation between knowledge and belief (Lenzen) and in an alleged refutation of verificationism (Fitch) and I examine an early argument (...) about the (im)possibility of epistemic logic (Hocutt). Subsequently, I deal with interpretive questions about epistemic logic that, although implicitly, already appeared in the first section. I contend that a conception of epistemic logic as a theory of knowledge assertions is incoherent, and I argue that it does not make sense to adopt a normative interpretation of epistemic logic. Finally, I show ways to extend epistemic logic with other branches of philosophical logic so as to make it useful for some epistemological questions. Conditional logics and logics of public announcement are used to understand causal theories of knowledge and versions of reliabilism. Temporal logic helps understand some dynamic aspects of knowledge as well as the verificationist thesis. (shrink)
Expressivist views of an area of discourse encourage us to ask not about the nature of the relevant kinds of values but rather about the nature of the relevant kind of evaluations. Their answer to the latter question typically claims some interesting disanalogy between those kinds of evaluations and descriptions of the world. It does so in hope of providing traction against naturalism-inspired ontological and epistemological worries threatening more ‘realist’ positions. This is a familiar position regarding ethical discourse; however, some (...) authors (e.g. Field, Heller, Gibbard, Blackburn, Chrisman) have recently defended a similar view regarding epistemic discourse. Others (especially Kvanvig, Cuneo, and Lynch) have argued that epistemic expressivism faces special problems, not necessarily attaching to expressivism about other areas. Their arguments differ in interesting ways, but the common strategy is an attempt to show that the very sort of meta-epistemological theorizing needed to articulate and establish epistemic expressivism involves the epistemic expressivist in some sort of internal incoherence or self-defeat. That is, they think that articulating or defending the position requires implicit commitment to the negation of one of the positions core tenets. This paper responds to those arguments on behalf of epistemic expressivism, suggesting that they each misunderstand what is crucial to epistemic expressivism. By responding to these arguments, we hope to achieve more clarity about what epistemic expressivism is and why one might want to endorse it in a meta-epistemology. (shrink)
The internalism/externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of knowledge and epistemic justification? It is generally held that if a positive epistemic status obtains, this is not a brute fact. Rather if a belief is, for example, justified, it is justified in virtue of some further condition(s) obtaining. What has been called epistemic internalism holds, as the label suggests, is that (...) all the relevant factors that determine justification must be “internal” (in a sense that needs to be specified). Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. <br> After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position (or family of positions). In addition to classical formulations, more recent formulations will be discussed, concluding with a discussion of an emerging position known as “Epistemological Disjunctivism”, which its advocates claim preserves the most important features of more traditional forms of internalism, while avoiding their difficulties. Epistemological Disjunctivism is particularly worthy of attention since if true, it promises to bridge internalist and externalist epistemologies, bringing a rapprochement to two sides of what may otherwise appear a deep and intractable debate about the fundamental nature of epistemology. <br>.

One of Kripke's fundamental objections to descriptivism was that the theory misclassifies certain _a posteriori_ propositions expressed by sentences involving names as _a priori_. Though nowadays very few philosophers would endorse a descriptivism of the sort that Kripke criticized, many find two-dimensional semantics attractive as a kind of successor theory. Because two-dimensionalism needn't be a form of descriptivism, it is not open to the epistemic argument as formulated by Kripke; but the most promising versions of two-dimensionalism are open to (...) a close relative of that argument.

Epistemic freedom is the freedom to affirm any one of several incompatible propositions without risk of being wrong. We sometimes have this freedom, strange as it seems, and our having it sheds some light on the topic of free will and determinism.
Knowledge ascriptions seem context sensitive. Yet it is widely thought that epistemic contextualism does not have a plausible semantic implementation. We aim to overcome this concern by articulating and defending an explicit contextualist semantics for ‘know,’ which integrates a fairly orthodox contextualist conception of knowledge as the elimination of the relevant alternatives, with a fairly orthodox “Amherst” semantics for A-quantification over a contextually variable domain of situations. Whatever problems epistemic contextualism might face, lack of an orthodox semantic implementation (...) is not among them. (shrink)
I define a property of beliefs - that of being structure-limning, or of “carving nature at the joints” - and propose three epistemological applications: (i) that limning structure has pro tanto epistemic value, (ii) that a species of understanding can be defined by appeal to the notion of limning structure, and (iii) that a distinction between important and trivial truths can be articulated by appeal to the notion of limning structure.
A popular account of epistemic justification holds that justification, in essence, aims at truth. An influential objection against this account points out that it is committed to holding that only true beliefs could be justified, which most epistemologists regard as sufficient reason to reject the account. In this paper I defend the view that epistemic justification aims at truth, not by denying that it is committed to epistemic justification being factive, but by showing that, when we focus (...) on the relevant sense of ‘justification’, it isn’t in fact possible for a belief to be at once justified and false. To this end, I consider and reject three popular intuitions speaking in favor of the possibility of justified false beliefs, and show that a factive account of epistemic justification is less detrimental to our normal belief forming practices than often supposed.

In this paper I consider a recent argument of Timothy Williamson’s that epistemic internalism and content externalism are indeed incompatible, and since he takes content externalism to be above reproach, so much the worse for epistemic internalism. However, I argue that epistemic internalism, properly understood, remains substantially unaffected no matter which view of content turns out to be correct. What is key to the New Evil Genius thought experiment is that, given everything of which the inhabitants are (...) consciously aware, the two worlds are subjectively indistinguishable for them, which is what matters on internalist accounts of epistemic justification. I argue that even if a standard moral of the New Evil Genius intuition is untenable due to considerations arising from content externalism, the case can be understood as supporting epistemic internalism in a way that is wholly compatible with content externalism. In short, epistemic internalism is committed to sameness of justificatory status between subjectively indistinguishable counterparts, not sameness of content of their justifiers. (shrink)
Do we apply higher epistemic standards to subjects with high stakes? This paper argues that we expect different outward behavior from high-stakes subjects—for example, we expect them to collect more evidence than their low-stakes counterparts—but not because of any change in epistemic standards. Rather, we naturally expect subjects in any condition to think in a roughly adaptive manner, balancing the expected costs of additional evidence collection against the expected value of gains in accuracy. The paper reviews a body (...) of empirical work on the automatic regulation of cognitive effort in response to stakes, and argues that we naturally see high- and low-stakes subjects as experiencing different levels of ‘epistemic anxiety’, and anticipate different levels of cognitive effort from them for this reason. If unresolved epistemic anxiety always bars an ascription of knowledge, then we can explain our responses to cases involving shifting stakes without positing any variation in the standards of intuitive knowledge ascription.

In this paper, I exploit the parallel between epistemic contextualism and metaethical speaker-relativism to argue that a promising way out of two of the primary problems facing contextualism is one already explored in some detail in the ethical case – viz. expressivism. The upshot is an argument for a form of epistemic expressivism modeled on a familiar form of ethical expressivism. This provides a new nondescriptivist option for understanding the meaning of knowledge attributions, which arguably better captures the (...) normative nature of epistemic discourse than descriptivist competitors like invariantism and contextualism.

Many philosophers have argued that an event is lucky for an agent only if it was suitably improbable, but there is considerable disagreement about how to understand this improbability condition. This paper argues for a hitherto overlooked construal of the improbability condition in terms of the lucky agent’s epistemic situation. According to the proposed account, an event is lucky for an agent only if the agent was not in a position to know that the event would occur. It is (...) also explored whether this new account threatens the anti-luck program in epistemology. It is argued that although not detrimental to the anti-luck program, the epistemic account of luck sets certain important limits to its scope and feasibility. (shrink)
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.
The lottery paradox can be solved if epistemic justification is assumed to be a species of permissibility. Given this assumption, the starting point of the paradox can be formulated as the claim that, for each lottery ticket, I am permitted to believe that it will lose. This claim is ambiguous between two readings, depending on the scope of ‘permitted’. On one reading, the claim is false; on another, it is true, but, owing to the general failure of permissibility to (...) agglomerate, does not generate the paradox. The solution generalizes to formulations of the paradox in terms of rational acceptability and doxastic rationality. (shrink)
In this paper, I argue that the “Ought Implies Can” (OIC) principle, as it is employed in epistemology, particularly in the literature on epistemic norms, is open to counterexamples. I present a counterexample to OIC and discuss several objections to it. If this counterexample works, then it shows that it is possible that S ought to believe that p, even though S cannot believe that p. If this is correct, then OIC, considered from an epistemic point of view, (...) is false, since it is supposed to hold for any S and any p. (shrink)
In this chapter, I produce counterexamples to Presuppositional Epistemic Contextualism (PEC), a view about the semantics of ‘knowledge’-ascriptions that I have argued for elsewhere. According to PEC, the semantic content of the predicate ‘know’ at a context C is partly determined by the speakers’ pragmatic presuppositions at C. The problem for the view that I shall be concerned with here arises from the fact that pragmatic presuppositions are sometimes known to be true by the speakers who make them: hence (...) the Problem of Known Presuppositions. After discussing several unsuccessful ways to solve the problem, I propose the addition of a new Lewisian rule of proper ignoring to the semantics of PEC--namely, the Rule of Evidence-Based Ignoring. If the proposed account succeeds, the Problem of Known Presuppositions has a straightforward solution within the framework of PEC. (shrink)
In this paper I will be concerned with the question as to whether expressivist theories of meaning can coherently be combined with deflationist theories of truth. After outlining what I take expressivism to be and what I take deflationism about truth to be, I’ll explain why I don’t take the general version of this question to be very hard, and why the answer is ‘yes’. Having settled that, I’ll move on to what I take to be a more pressing and (...) interesting version of the question, arising from a prima facie tension between deflationism about truth and the motivations underlying expressivism for what I take to be two of its most promising applications: to indicative conditionals and epistemic modals. Here I’ll argue that the challenge is substantive, but that there is no conceptual obstacle to its being met, provided that one’s expressivism takes the right form. (shrink)
On Kratzer’s canonical account, modal expressions (like “might” and “must”) are represented semantically as quantifiers over possibilities. Such expressions are themselves neutral; they make a single contribution to determining the propositions expressed across a wide range of uses. What modulates the modality of the proposition expressed—as bouletic, epistemic, deontic, etc.—is context.2 This ain’t the canon for nothing. Its power lies in its ability to figure in a simple and highly unified explanation of a fairly wide range of language use. (...) Recently, though, the canon’s neat story has come under attack. The challenge cases involve the epistemic use of a modal sentence for which no single resolution of the contextual parameter appears capable of accommodating all our intuitions.3 According to these revisionaries, such cases show that the canonical story needs to be amended in some way that makes multiple bodies of information relevant to the assessment of such statements. Here I show that how the right canonical, flexibly contextualist account of modals can accommodate the full range of challenge cases. The key will be to extend Kratzer’s formal semantic account with an account of how context selects values for a modal’s.. (shrink)
Although several important methodologies implicitly assume the truth of epistemic conservatism, the view that holding a belief confers some measure of justification on the belief, recent criticisms have led some to conclude that epistemic conservatism is an implausible view. That conclusion is mistaken. In this article, I propose a new formulation of epistemic conservatism that is not susceptible to the criticisms leveled at earlier formulations of epistemic conservatism. In addition to withstanding these criticisms, this formulation of (...)epistemic conservatism has several benefits. First, this formulation has the benefits of earlier formulations of epistemic conservatism, that is to say it makes sense of our intuitions about justification in regard to both memory beliefs and beliefs for which we have forgotten our evidence. Second, it provides a good way of responding to the skeptic’s challenge concerning the possibility of possessing knowledge of the external world posed by the Alternative Hypotheses argument. Third, it provides responses to both forms of a new skeptical problem plaguing basic knowledge structure theories, the Problem of Easy Knowledge formulated by Stewart Cohen. I argue that given the many benefits of this formulation of epistemic conservatism and the fact that it is not vulnerable to the criticisms that undermine earlier formulations of epistemic conservatism, this formulation of epistemic conservatism is a plausible view to maintain.

Conservatism about perceptual justification tells us that we cannot have perceptual justification to believe p unless we also have justification to believe that perceptual experiences are reliable. There are many ways to maintain this thesis, ways that have not been sufficiently appreciated. Most of these ways lead to at least one of two problems. The first is an over-intellectualization problem, whereas the second problem concerns the satisfaction of the epistemic basing requirement on justified belief. I argue that there is (...) at least one Conservative view that survives both difficulties, a view which has the further ability to undercut a crucial consideration that has supported Dogmatist views about perceptual justification. The final section explores a tension between Conservatism and the prospects of having a completely general account of propositional justification. Ironically, the problem is that Conservatives seem committed to making the acquisition of propositional justification too easy. My partial defense of Conservatism concludes by suggesting possible solutions to this problem. (shrink)
My NCPS 2012 conference paper. The paper is a development of the abstract below. The file you can upload contains my brief "A Fast & Frugal Rebuttal of Epistemic Situationism," while the whole paper develops a fuller reply to the Alfano, and Doris and Olin papers also presented in this session, papers in which these authors extend the "situationist challenge" to virtue ethics, to different varieties of virtue epistemology. Abstract. This paper mounts an empirically-based rebuttal to the radical implications (...) that self-described “epistemic situationists” including Mark Alfano and John Doris would have us draw from mood and conformity studies. The compatibility of virtue epistemologies with dual process theory (Kahneman; Stanovich) in cognitive and social psychology is developed as one main way of defending the empirical adequacy of many or most forms of virtue epistemology. Although philosophical situationists ignore dual process models of human reasoning, I argue that the latter offer ample empirical support for the “psychological realizability” of the intellectual character-traits posited by virtue-focused epistemologies and featured in the credit theory of knowing.

Control of our own beliefs is allegedly required for the truth of epistemic evaluations, such as S ought to believe that p , or S ought to suspend judgment (and so refrain from any belief) whether p . However, we cannot usually believe or refrain from believing at will. I agree with a number of recent authors in thinking that this apparent conflict is to be resolved by distinguishing reasons for believing that give evidence that p from reasons that (...) make it desirable to believe that p whether or not p is true. I argue however that there is a different problem, one that becomes clearer in light of this solution to the first problem. Someone’s approval of our beliefs is at least often a non-evidential reason to believe, and as such cannot change our beliefs. Ought judgments aim to change the world. But ‘ought to believe’ judgments can’t do that by changing the belief, if they don’t give evidence. So I argue that we should instead regard epistemic ought judgments as aimed mainly at influencing assertions that express the belief and other actions based on the belief, in accord with recent philosophical claims that we have epistemic norms for assertion and action.

Evidentialism as its leading proponents describe it has two distinct senses, these being evidentialism as a conceptual analysis of epistemic justification, and as a prescriptive ethics of belief—an account of what one ‘ought to believe’ under different epistemic circumstances. These two senses of evidentialism are related, but in the work of leading evidentialist philosophers, in ways that I think are deeply problematic. Although focusing on Richard Feldman’s ethics of belief, this chapter is critical of evidentialism in both senses. (...) However, I share with authors like Feldman and Earl Conee, that epistemology has important prescriptive functions, and that a sound, civic ethics of belief is of more than merely philosophic importance. One reason why an ethics of belief might be important to problems of practice is the need we have for tools to more effectively mediate the renewed round of ‘culture wars’ we are experiencing in Anglo-American cultures. I mean especially that grand cultural clash between science and religion, reason and faith, secularist atheism and religious fundamentalism, etc. Let us start with the genealogical question of why there is such a grand cultural debate in the first place, and why the debate especially as played out in public and popular forums and even in the courtrooms seems so volatile and so often to confusedly drag everything—beliefs, values, passions, etc., with it. These are questions that I think Sigmund Freud’s classic Civilization and its Discontents can help us understand. Freud was a major voice in criticism of the stern and often hypocritical Victorian morality, a voice pointing out the price of its sometimes high-handed, guiltinducing curtailments of the satisfactions sought by the individual. But for Freud while there are real differences in the moral demands that different societies or traditions place upon people, there is something inevitable about the conflict itself, for “replacement of the power of the individual by the power of a community constitutes the decisive step of civilization...

Does game theory—the mathematical theory of strategic interaction—provide genuine explanations of human behaviour? Can game theory be used in economic consultancy or other normative contexts? Explaining Games: The Epistemic Programme in Game Theory—the first monograph on the philosophy of game theory—is an attempt to combine insights from epistemic logic and the philosophy of (...) science to investigate the applicability of game theory in such fields as economics, philosophy and strategic consultancy. I prove new mathematical theorems about the beliefs, desires and rationality principles of individual human beings, and explore in detail the logical form of game theory as it is used in explanatory and normative contexts. I argue that game theory reduces to rational choice theory if used as an explanatory device, and that game theory is nonsensical if used as a normative device. A provocative account of the history of game theory reveals that this is not bad news for all of game theory, though. Two central research programmes in game theory tried to find the ultimate characterisation of strategic interaction between rational agents. Yet, while the Nash Equilibrium Refinement Programme has done badly thanks to such research habits as overmathematisation, model-tinkering and introversion, the Epistemic Programme, I argue, has been rather successful in achieving this aim. "The 'epistemic' approach to game theory has emerged over the past twenty-five years. What is this approach? How does it differ from the conventional equilibrium-based approach to game theory? What have been its strengths and weaknesses to date? To find out, read this comprehensive and excellently written account". Adam Brandenburger, J. P. Valles Professor of Business Economics and Strategy, Stern School of Business, New York University "Reading Boudewijn de Bruin's book should be rewarding both for game theorists interested in the conceptual foundations of their discipline and for philosophers who want to learn more about formal analysis of strategic interaction. It provides an in-depth logical study of the currently dominant epistemic approaches to non-cooperative games, with an eye both to the attractions and to the serious challenges facing the Epistemic Programme".

Though it seems rather surprising in retrospect, until about twenty-five years ago no philosopher in the Western tradition had explicitly formulated the question whether there could be an epistemic analogue to practical akrasia. Also surprisingly, despite the prima facie analogue with practical akrasia (the possibility of which is not much disputed), much of the recent work on this question has defended the rather bold view that epistemic akrasia is impossible. While the arguments purporting to show the impossibility of (...)epistemic akrasia have been criticized by some, I propose instead to make a head-on attack and defend the substantive view that epistemic akrasia is possible — indeed, actual. This leaves for another day the project of diagnosing exactly where the arguments for the impossibility of epistemic akrasia go wrong. Here, I content myself with trying to show that they must go wrong, since — as I will argue — epistemic akrasia is possible. (shrink)
In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a trivial dispute (...) is appropriate because the disputing parties are usually epistemic peers within the relevant domain, whereas in a more substantial disagreement the disputing parties rarely, if ever, qualify as epistemic peers, and so ‘sticking to one’s guns’ is usually the appropriate doxastic response. My aim in this paper is to explain why this way of drawing the desired distinction is ultimately problematic, even if it seems promising at first blush. (shrink)
In “Epistemic Modals,” Seth Yalcin argues that what explains the deficiency of sentences containing epistemic modals of the form ‘p and it might be that not-p’ is that sentences of this sort are strictly contradictory, and thus are not instances of a Moore-paradox as has been previous suggested. Benjamin Schnieder, however, argues in his Yalcin’s explanation of these sentences’ deficiency turns out to be insufficiently general, as it cannot account for less complex but still defective sentences, such as (...) ‘Suppose it might be raining.’ Consequently, Schnieder proposes his own, expressivist treatment of epistemic modals which he thinks can explain the deficiency of both the original sentence type as well as more complex cases of embedded sentences containing epistemic modals. In this study, I argue that although Schnieder is right to draw our attention to the explanatory failure of Yalcin’s account, we aren’t forced to adopt Schnieder’s expressivist account of epistemic modals. I defend instead a contextualist-friendly alternative which explains the deficiencies of all the relevant sentence types, while avoiding both the defects of Yalcin’s account and the intuitive costs of expressivism.

The following analysis shows how developments in epistemic logic can play a nontrivial role in cognitive neuroscience. We argue that the striking correspondence between two modes of identification, as distinguished in the epistemic context, and two cognitive systems distinguished by neuroscientific investigation of the visual system (the "where" and "what" systems) is not coincidental, and that it can play a clarificatory role at the most fundamental levels of neuroscientific theory.
The paper is concerned with the semantics of knowledge attributions(K-claims, for short) and proposes a position holding that K-claims are contextsensitive that differs from extant views on the market. First I lay down the data a semantic theory for K-claims needs to explain. Next I present and assess three views purporting to give the semantics for K-claims: contextualism, subject-sensitive invariantism and relativism. All three views are found wanting with respect to their accounting for the data. I then propose a hybrid (...) view according to which the relevant epistemic standards for evaluating K-claims are neither those at the context of the subject (subject-sensitive invariantism), nor those at the context of the assessor (relativism), but it is itself an open matter. However, given that we need a principled way of deciding which epistemic standards are the relevant ones, I provide a principle according to which the relevant standards are those that are the highest between those at the context of the subject and those at the context of the assessor/attributor. In the end I consider some objections to the view and offer some answers. (shrink)
In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one (...) knows that they do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

The article suggests a reading of the term ‘epistemic account of truth’ which runs contrary to a widespread consensus with regard to what epistemic accounts are meant to provide, namely a definition of truth in epistemic terms. Section 1. introduces a variety of possible epistemic accounts that differ with regard to the strength of the epistemic constraints they impose on truth. Section 2. introduces the paradox of knowability and presents a slightly reconstructed version of a (...) related argument brought forward by Wolfgang Künne. I accept the paradox and Künnes argument as sound objections to all the different epistemic accounts which are committed to one of the various constraints on truth introduced in section 1. Section 3. offers a modified epistemic constraint which, or so I argue, is immune to the paradox of knowability and plausible on independent grounds. (shrink)
Epistemologists often assume that an agent’s epistemic goal is simply to acquire as much knowledge as possible for herself. Drawing on an analogy with ethics and other practices, I argue that being situated in an epistemic community introduces a range of epistemic virtues (and goals) which fall outside of those typically recognized by both individualistic and social epistemologists. Candidate virtues include such traits as honesty, integrity (including an unwillingness to misuse one’s status as an expert), patience, and (...) creativity. We can understand such traits to be epistemic virtues insofar as they tend to produce knowledge – not for the agent alone, but for her community. Recognition of such ‘otherregarding epistemic virtues’ both broadens the area of inquiry of epistemology, and introduces new standards for the evaluation of epistemic agents. (shrink)
Knowledge seems to be a good thing, or at least better than epistemic states that fall short of it, such as true belief. Understanding too seems to be a good thing, perhaps better even than knowledge. In a number of recent publications, Duncan Pritchard tries to account for the value of understanding by claiming that understanding is a cognitive achievement and that achievements in general are valuable. In this paper, I argue that coming to understand something need not be (...) an achievement, and so Pritchard's explanation of understanding's value fails. Next, I point out that Pritchard's is just one of many attempts to account for the value of an epistemic state – whether it be understanding, knowledge, or whatever – by appeal to the notion of achievement or, more generally, the notion of success because of ability. Tentatively, I offer reasons to be sceptical about the prospects of any such account. (shrink)
This paper addresses a problem for theories of epistemic democracy. In a decision on a complex issue which can be decomposed into several parts, a collective can use different voting procedures: Either its members vote on each sub-question and the answers that gain majority support are used as premises for the conclusion on the main issue (premise based-procedure, pbp), or the vote is conducted on the main issue itself (conclusion-based procedure, cbp). The two procedures can lead to different results. (...) We investigate which of these procedures is better as a truth-tracker, assuming that there exists a true answer to be reached. On the basis of the Condorcet jury theorem, we show that the pbp is universally superior if the objective is to reach truth for the right reasons. If one instead is after truth for whatever reasons, right or wrong, there will be cases in which the cbp is more reliable, even though, for the most part, the pbp still is to be preferred. (shrink)
An epistemic duty would be a duty to believe, disbelieve, or withhold judgment from a proposition, and it would be grounded in purely evidential or epistemic considerations. If I promise to believe it is raining, my duty to believe is not epistemic. If my evidence is so good that, in light of it alone, I ought to believe it is raining, then my duty to believe supposedly is epistemic. I offer a new argument for the claim (...) that there are no epistemic duties. Though people do sometimes have duties to believe, disbelieve, or withhold judgment from propositions, those duties are never grounded in purely epistemic considerations. (shrink)
This paper begins by raising a puzzle about what function our use of the word ‘rational’ could serve. To solve the puzzle, I introduce a view I call Epistemic Communism: we use epistemic evaluations to promote coordination among our basic belief-forming rules, and the function of this is to make the acquisition of knowledge by testimony more efficient.
To lead an environmentally virtuous life requires information—about morality, environmental issues, the impacts of our actions and commitments, our options for alternatives, and so on. On the other hand, we are finite beings with limited time and resources. We cannot feasibly investigate all of our options, and all environmental issues (let alone moral issues, more broadly). In this paper I attempt to provide initial steps towards addressing the epistemic demands of environmental virtue. In the first half of the paper (...) I provide rules of thumb with respect to (1) how to prioritize our investigations into various issues, and (2) what kinds of information we should seek with respect to these issues, and the levels of epistemic justification we ought to attain. In the second half of the paper, I turn to a modified virtue ethics, appealing to the attitudes of virtuous ideal observers to provide characterizations of morally justified and morally non-culpable actions. I then apply these latter concepts in assessing agents, their actions and projects (with respect to environmental virtue), in light of their investigative efforts, and given their particular circumstances.

This paper presents and discusses a range of counterexamples to the common view that quantifiers cannot take scope over epistemic modals. Some of the counterexamples raise problems for ‘force modifier’ theories of epistemic modals. Some of the counterexamples raise problems for Robert Stalnaker’s theory of counterfactuals, according to which a special kind of epistemic modal must be able to scope over a whole counterfactual. Finally, some of the counterexamples suggest that David Lewis must countenance ‘would’ counterfactuals in (...) which a covert ‘would’ scopes over the whole consequent of the counterfactual, including an overt ‘might.’.

This paper explores the relationship between scepticism and epistemic relativism in the context of recent history and philosophy of science. More specifically, it seeks to show that significant treatments of epistemic relativism by influential figures in the history and philosophy of science draw upon the Pyrrhonian problem of the criterion. The paper begins with a presentation of the problem of the criterion as it occurs in the work of Sextus Empiricus. It is then shown that significant treatments of (...)epistemic relativism in recent history and philosophy of science (critical rationalism, historical philosophy of science and the strong programme) draw upon the problem of the criterion. It is briefly suggested that a particularist response to the problem of the criterion may be put to good use against epistemic relativism. (shrink)
In this chapter, I argue for the thesis that phenomenal consciousness is the basis of epistemic justification. More precisely, I argue for the thesis of phenomenal mentalism, according to which epistemic facts about which doxastic attitudes one has justification to hold are determined by non-epistemic facts about one’s phenomenally individuated mental states. I begin by providing intuitive motivations for phenomenal mentalism and then proceed to sketch a more theoretical line of argument according to which phenomenal mentalism provides (...) the best explanation of the independently motivated thesis of access internalism. The result is a theory of epistemic justification that brings intuition and theory into reflective equilibrium. (shrink)
Michael Huemer (2007) has articulated a provocative account of the concept of "epistemic possibility" which he hopes will explicate the explanatory value of the concept while also lending support to a broader anti-skeptical strategy. While I think his account has a number of advantages, many of which Huemer himself identifies, there are also significant disadvantages which should prompt us to seek an alternative. In this paper I describe an alternative which builds on some of the better features of Huemer's (...) account, while avoiding its shortcomings. After having explained why this alternative avoids the problems I attribute to Huemer's position, I will conclude by presenting some independent considerations in favor of my account, which recommends that epistemic possibility claims be subjected to the same evidentialist standards to which belief and assertion are usually held accountable.

Philosophers, especially in recent years, have engaged in reflection upon the nature of experience. Such reflections have led them to draw a distinction between conscious and unconscious mentality in terms of whether or not it is like something to have a mental state. Reflection upon the history of psychology and upon contemporary cognitive science, however, identifies the distinction between conscious and unconscious mental states to be primarily one which is drawn in epistemic terms. Consciousness is an epistemic not (...) ion marking the special kind of first-person knowledge we have of our own mental states. Psychologists have found it expedient, for explanatory reasons, to ignore or reject the assumption that we have exhaustive first-person knowledge of our mental states and, in doing so, use the term �unconscious� to indicate the peculiar epistemic status of certain mental states. It is argued that epistemic consciousness is distinct from the subjective-experiential notion of consciousness, from �access-consciousness� and from higher-order thought conceptions of mental state consciousness, and that epistemic consciousness has an important role to play in philosophy of mind and in the history of psychology.

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.
In this paper I will argue that Regan’s subjects-of-a-life account is epistemically irresponsible. Firstly, in making so many epistemic claims. Secondly in making the claims themselves.
In ' Unnatural Doubts' Michael Williams argues that Cartesian skepticism is not truly an "intuitive problem" (that is, one which we can state with little or no appeal to contentious theories) at all. According to Williams, the skeptic has rich theoretical commitments all his own, prominent among which is the epistemic priority thesis. I argue, however, that Williams's diagnostic critique of the epistemic priority thesis fails on his own conception of what is required for success. Furthermore, in a (...) brief "Afterword" I argue that the later Wittgenstein (to whom Williams sometimes appeals) would concur with my critique of Williams's antiskeptical efforts. (shrink)
According to Epistemic Two-Dimensional Semantics (E2D), expressions have a counterfactual intension and an epistemic intension. Epistemic intensions reflect cognitive significance such that sentences with necessary epistemic intensions are a priori. We defend E2D against an influential line of criticism: arguments from epistemic misclassification. We focus in particular on the arguments of Speaks [2010] and Schroeter [2005]. Such arguments conclude that E2D is mistaken from (i) the claim that E2D is committed to classifying certain sentences as (...) a priori, and (ii) the claim that such sentences are a posteriori. We aim to show that these arguments are unsuccessful as (i) and (ii) undercut each other. One must distinguish the general framework of E2D from a specific implementation of it. The framework is flexible enough to avoid commitment to the apriority of any particular sentence; only specific implementations are so committed. Arguments from epistemic misclassification are therefore better understood as arguments for favouring one implementation of E2D over another, rather than as refutations of E2D. (shrink)
Tyler Burge's critique of individualistic conceptions of mental content is well known.This paper employs a novel strategy to defend a strong form of Burge's conclusion. The division of epistemic labor rests on the possibility of language-mediated transactions, such as asking for something in a store and getting it. The paper shows that any individualistic conception of content will render such transactions unintelligible.
This paper discusses the possibility of modelling inductive inference (Gold 1967) in dynamic epistemic logic (see e.g. van Ditmarsch et al. 2007). The general purpose is to propose a semantic basis for designing a modal logic for learning in the limit. First, we analyze a variety of epistemological notions involved in identification in the limit and match it with traditional epistemic and doxastic logic approaches. Then, we provide a comparison of learning by erasing (Lange et al. 1996) and (...) iterated epistemic update (Baltag and Moss 2004) as analyzed in dynamic epistemic logic. We show that finite identification can be modelled in dynamic epistemic logic, and that the elimination process of learning by erasing can be seen as iterated belief-revision modelled in dynamic doxastic logic. Finally, we propose viewing hypothesis spaces as temporal frames and discuss possible advantages of that perspective. (shrink)
Throughout his work on the rationality of epistemic dependence, John Hardwig makes the striking observation that he believes many things for which he possesses no evidence (1985, 335; 1991, 693; 1994, 83). While he could imagine collecting for himself the relevant evidence for some of his beliefs, the vastness of the world and constraints of time and individual intellect thwart his ability to gather for himself the evidence for all his beliefs. So for many things he believes what others (...) tell him, as we all do. Epistemic dependence is the responsible choice, he argues, because he can be reasonably sure that those on whom he depends know more about the subject than he does. Epistemic dependence on experts is a smarter bet than epistemic autonomy: after all, Hardwig reasons, “if I were to pursue epistemic autonomy across the board, I would succeed in holding relatively uninformed, unreliable, crude, untested, and therefore irrational beliefs” (1985, 340) [...] In this paper I argue against what I call Hardwig’s no-evidence thesis: that knowledge and belief based on testimony are knowledge and belief for which the knower possesses no evidence. Against the no-evidence thesis, I propose we recognize that layperson B’s good reason to believe that expert A has good reason to believe proposition p constitutes evidence for B for p. I argue that the reasons Hardwig gives for the no-evidence thesis are inconclusive at best; at worst the no-evidence thesis coupled with his recognition of expert interdependence exposes him to recent criticisms by Stella Gaon and Stephen Norris. By rejecting the no-evidence thesis, we can recognize with Hardwig the importance of expert epistemic interdependence while avoiding the paradoxical implications of his position. (shrink)
When extended cognition is extended into mainstream epistemology, an awkward tension arises when considering cases of environmental epistemic luck. Surprisingly, it is not at all clear how the mainstream verdict that agents lack knowledge in cases of environmental luck can be reconciled with principles central to extended cognition.
The paper argues that the Nash Equilibrium Refinement Programme in game theory was less successful than its competitor, the Epistemic Programme (Interactive Epistemology). The prime criterion of success is the extent to which the programmes were able to reach the key objective guiding non-cooperative game theory for much of the 20th century, namely, to develop a complete characterisation of the strategic rationality of economic agents in the form of the ultimate game theoretic solution concept for any normal form and (...) extensive game. The paper explains this in terms of unjustified degrees of mathematisation in the Nash Equilibrium Refinement Programme. While this programme's mathematical models were often inspired by purely mathematical concerns rather than the economic phenomena they were intended to be mathematical models of, the Epistemic Programme's mathematical models were developed with a keen eye to the role beliefs and desires play in strategic interaction between rational economic agents playing games; that is, their Interactive Epistemology. The Epistemic Programme succeeded in developing mathematical models formalising aspects of strategic interaction that remained implicit in the Nash Equilibrium Refinement Programme due to an unjustified degree of mathematisation. As a result, the Epistemic Programme is more successful in game theory . (shrink)
In this paper, I consider an argument of Harvey Siegel's according to which there can be no hypothetical normativity anywhere unless there is categorical normativity in epistemology. The argument fails because it falsely assumes people must be bound by epistemic norms in order to have justified beliefs.
Epistemic transparency tells us that, if an agent S knows a given proposition p , then S knows that she knows that p . This idea is usually encoded in the so-called KK principle of epistemic logic. The paper develops an argument in favor of a moderate version of KK , which I dub quasi-transparency , as a normative rather than a descriptive principle. In the second Section I put forward the suggestion that epistemic transparency is not (...) a demand of ideal rationality, but of ideal epistemic responsibility, and hence that ideally responsible agents verify transparency principles of some sort; I also contend that their satisfaction should not be tied to an internalist epistemology. The central argument in favor of transparency is then addressed in Sections 3 to 8, through the development of a formal system. I show that, in a well-behaved formal setting, a moderate version of transparency is imposed upon us as a result of a number of independent decisions on the structure of higher-order probabilities, as long as we request that our probability and knowledge attributions cohere with each other. Thus I give a rationale to build a model for a hierarchy of languages with different levels of knowledge and probability operators; we obtain an analogous to KK for successive knowledge operators without actually demanding transitivity. The formal argument reinforces the philosophical intuition that epistemic transparency is an important desideratum we should not be too ready to dismiss. (shrink)
In this paper, I raise two questions about epistemic commitments, and thus, indirectly, about our epistemic agency. Can we rationally defend such commitments when challenged to do so? And if so, how?
Several philosophers have argued that the factivity of knowledge poses a problem for epistemic contextualism (EC), which they have construed as a knowability problem. On a proposed minimalistic reading of EC’s commitments, Wolfgang Freitag argues that factivity yields no knowability problem for EC. I begin by explaining how factivity is thought to generate a contradiction out of paradigmatic contextualist cases on a certain reading of EC’s commitments. This reductio results in some kind of reflexivity problem for the contextualist when (...) it comes to knowing her theory: either a knowability problem or a statability problem. Next, I set forth Freitag’s minimalistic reading of EC and explain how it avoids the reductio, the knowability problem and the statability problem. I argue that despite successfully evading these problems, Freitag’s minimalistic reading saddles EC with several other serious problems and should be rejected. I conclude by offering my own resolution to the problems. (shrink)
Epistemic trust is crucial for science. This article aims to identify the kinds of assumptions that are involved in epistemic trust as it is required for the successful operation of science as a collective epistemic enterprise. The relevant kind of reliance should involve working from the assumption that the epistemic endeavors of others are appropriately geared towards the truth, but the exact content of this assumption is more difficult to analyze than it might appear. The root (...) of the problem is that methodological decisions in science typically involve a complex trade-off between the reliability of positive results, the reliability of negative results, and the investigation's power (the rate at which it delivers definitive results). Which balance between these is the ‘correct’ one can only be determined in light of an evaluation of the consequences of all the different possible outcomes of the inquiry. What it means for the investigation to be ‘appropriately geared towards the truth’ thus depends on certain value judgments. I conclude that in the optimal case, trusting someone in her capacity as an information provider also involves a reliance on her having the right attitude towards the possible consequences of her epistemic work. 1 Introduction2 Epistemic Reliance within the Sciences3 Methodological Conventionalism4 Trust in Science5 Conclusions.

It is widely acknowledged that epistemic modals admit of inter-subjective flexibility. This paper introduces intra-subjective flexibility for epistemic modals and draws on this flexibility to argue that fallibilism is consistent with the standard account of epistemic modals.
In this essay I present a new version of the Paradox of the Knower and show that this new paradox vitiates a certain argument against epistemic closure. I then prove a theorem that relates the new paradox to epistemological scepticism. I conclude by assessing the use of the Knower in arguments against syntactical treatments of knowledge.
I claim that caricature is an epistemically defective depiction. More precisely, when employed in service to some epistemic uptake, I claim that caricature can have a non-negligible epistemic effect only for a less than ideally rational audience with certain cognitive biases. An ideally rational audience, however, would take all caricature to be what I refer to as fairground caricature, i.e., an interesting or entertaining form of depiction that is at best only trivially revelatory. I then argue that any (...) medium (or genre) substantially employing caricature (or standardly featuring or prescribing its employment) in service to some epistemic uptake is to that extent an epistemically defective medium (e.g., beliefs informed by works specific to that medium are to that extent unwarranted). I then show the editorial cartoon to be just such an epistemically defective medium. (shrink)
I shall first briefly revisit the broad idea of ‘epistemic injustice’, explaining how it can take either distributive or discriminatory form, in order to put the concepts of ‘testimonial injustice’ and ‘hermeneutical injustice’ in place. In previous work I have explored how the wrong of both kinds of epistemic injustice has both an ethical and an epistemic significance—someone is wronged in their capacity as a knower. But my present aim is to show that this wrong can also (...) have a political significance in relation to non-domination, and so to freedom. While it is only the republican conception of political freedom that presents nondomination as constitutive of freedom, I shall argue that non-domination is best understood as a thoroughly generic liberal ideal of freedom to which even negative libertarians are implicitly committed, for non-domination is negative liberty as of right—secured non-interference. Crucially on this conception, non-domination requires that the citizen can contest interferences. Pettit specifies three conditions of contestation, each of which protects against a salient risk of the would-be contester not getting a ‘proper hearing’. But I shall argue that missing from this list is anything to protect against a fourth salient threat: the threat that either kind of epistemic injustice might disable contestation by way of an unjust deflation of either credibility or intelligibility. Thus we see that both testimonial and hermeneutical injustice can render a would-be contester dominated. Epistemic justice is thereby revealed as a constitutive condition of non-domination, and thus of a central liberal political ideal of freedom. (shrink)
This paper argues in favor of the epistemic properties of inclusiveness in the context of democratic deliberative assemblies and derives the implications of this argument in terms of the epistemically superior mode of selection of representatives. The paper makes the general case that, all other things being equal and under some reasonable assumptions, more is smarter. When applied to deliberative assemblies of representatives, where there is an upper limit to the number of people that can be included in the (...) group, the argument translates into a defense of a specific selection mode of participants: random selection.

The paper defends the thesis that our epistemic duty is the duty to proportion our beliefs to the evidence we possess. An inclusive view of evidence possessed is put forward on the grounds that it makes sense of our intuitions about when it is right to say that a person ought to believe some proposition P. A second thesis is that we have no epistemic duty to adopt any particular doxastic attitudes. The apparent tension between the two theses (...) is resolved by applying the concept of duty to belief indirectly. (shrink)
Although epistemic possibility figures in several debates, those debates have had relatively little contact with one another. G. E. Moore focused squarely upon analyzing epistemic uses of the phrase, ‘It’s possible that p’, and in doing so he made two fundamental assumptions. First, he assumed that epistemic possibility statements always express the epistemic position of a community, as opposed to that of an individual speaker. Second, he assumed that all epistemic uses of ‘It’s possible that (...) p’ are analyzable in terms of knowledge, not belief. A number of later theorists, including Keith DeRose, provide alternative accounts of epistemic possibility, while retaining Moore’s two assumptions. Neither assumption has been explicitly challenged, but Jaakko Hintikka’s analysis provides a basis for doing so. Drawing upon Hintikka’s analysis, I argue that some epistemic possibility statements express only the speaker’s individual epistemic state, and that contra DeRose, they are not degenerate community statements but a class in their own right. I further argue that some linguistic contexts are belief- rather than knowledge-based, and in such contexts, what is possible for a speaker depends not upon what she knows, but upon what she believes.

In this article I argue that Alston’s recent meta-epistemological approach in terms of epistemic desiderata is not as epistemically plural as he claims it to be. After some preliminary remarks, I briefly recapitulate Alston’s epistemic desiderata approach. Next, I distinguish two ways in which one might consider truth to be an epistemic desideratum. Subsequently, I argue that only one truth-conducive desideratum can count as an epistemic desideratum. After this, I attempt to show that none of the (...) higher-order desiderata that are thought to be favorable to the discrimination and formation of true beliefs are genuinely epistemic desiderata. A strict interpretation of ‘epistemic desideratum’ leads to a rejection of all deontological desiderata as well. Finally, features of systems of beliefs, such as coherence and understanding, cannot count as epistemic desiderata either. In the end only two candidate-desiderata can count as epistemic, one of which is logically trivial. In the epilogue, I offer some suggestions as to how Alston’s epistemic desiderata approach should be amended in order to make it epistemically plural. (shrink)
This paper revisits one of the key ideas developed in The Structure of Scientific Revolutions. In particular, it explores the methodological form of incommensurability which may be found in the original edition of Structure. It is argued that such methodological incommensurability leads to a form of epistemic relativism. In later work, Kuhn moved away from the original idea of methodological incommensurability with his idea of a set of epistemic values that provides a basis for rational theory choice, but (...) do not constitute an algorithm for such choice. The paper also explores the sceptical basis for the epistemic relativism of the original view that Kuhn proposes in Structure. It suggests that the main sceptical rationale for such relativism may be avoided by a particularist and naturalist conception of epistemic normativity. When this approach is combined with the appeal to external methodological standards endorsed by the later Kuhn and his critics, the epistemic relativism of Structure may be completely repudiated.

We argue that non-epistemic values, including moral ones, play an important role in the construction and choice of models in science and engineering. Our main claim is that non-epistemic values are not only “secondary values” that become important just in case epistemic values leave some issues open. Our point is, on the contrary, that non-epistemic values are as important as epistemic ones when engineers seek to develop the best model of a process or problem. The (...) upshot is that models are neither value-free, nor depend exclusively on epistemic values or use non-epistemic values as tie-breakers. (shrink)
Epistemic closure has been a central issue in epistemology over the last forty years. According to versions of the relevant alternatives and subjunctivist theories of knowledge, epistemic closure can fail: an agent who knows some propositions can fail to know a logical consequence of those propositions, even if the agent explicitly believes the consequence (having “competently deduced” it from the known propositions). In this sense, the claim that epistemic closure can fail must be distinguished from the fact (...) that agents do not always believe, let alone know, the consequences of what they know—a fact that raises the “problem of logical omniscience” that has been central in epistemic logic. -/- This paper, part I of II, is a study of epistemic closure from the perspective of epistemic logic. First, I introduce models for epistemic logic, based on Lewis’s models for counterfactuals, that correspond closely to the pictures of the relevant alternatives and subjunctivist theories of knowledge in epistemology. Second, I give an exact characterization of the closure properties of knowledge according to these theories, as formalized. Finally, I consider the relation between closure and higher-order knowledge. The philosophical repercussions of these results and results from part II, which prompt a reassessment of the issue of closure in epistemology, are discussed further in companion papers. -/- As a contribution to modal logic, this paper demonstrates an alternative approach to proving modal completeness theorems, without the standard canonical model construction. By “modal decomposition” I obtain completeness and other results for two non-normal modal logics with respect to new semantics. One of these logics, dubbed the logic of ranked relevant alternatives, appears not to have been previously identified in the modal logic literature. More broadly, the paper presents epistemology as a rich area for logical study. (shrink)
Formal learning theory constitutes an attempt to describe and explain the phenomenon of learning, in particular of language acquisition. The considerations in this domain are also applicable in philosophy of science, where it can be interpreted as a description of the process of scientific inquiry. The theory focuses on various properties of the process of hypothesis change over time. Treating conjectures as informational states, we link the process of conjecture-change to epistemic update. We reconstruct and analyze the temporal aspect (...) of learning in the context of dynamic and temporal logics of epistemic change. We first introduce the basic formal notions of learning theory and basic epistemic logic. We provide a translation of the components of learning scenarios into the domain of epistemic logic. Then, we propose a characterization of finite identifiability in an epistemic temporal language. In the end we discuss consequences and possible extensions of our work. (shrink)
This essay corrects an error in the presentation of the Paradox of the Knowledge-Plus Knower, which is the variant of Kaplan and Montague’s Knower Paradox presented in C. Cross 2001: ‘The Paradox of the Knower without Epistemic Closure,’ MIND, 110, pp. 319–33. The correction adds a universally quantified transitivity principle for derivability as an additional assumption leading to paradox. This correction does not affect the status of the Knowledge-Plus paradox as a rebuttal to an argument against epistemic closure, (...) since the quantified transitivity principle is true in the standard model of arithmetic and therefore innocuous.

Syntactic logics do not suffer from the problems of logical omniscience but are often thought to lack interesting properties relating to epistemic notions. By focusing on the case of rule-based agents, I develop a framework for modelling resource-bounded agents and show that the resulting models have a number of interesting properties.
In “The Paradox of the Knower without Epistemic Closure”, MIND 110:319-33, 2001, I develop a version of the Knower Paradox which does not assume epistemic closure, and I use it to argue that the original Knower Paradox does not support an argument against epistemic closure. In “The Paradox of the Knower without Epistemic Closure?”, MIND 113:95-107, 2004, Gabriel Uzquiano, using his own result, argues that my rebuttal to the anti-closure argument is not successful. I respond here (...) by arguing that in order to use Uzquiano’s result in an argument against closure, one must assume an implausible skepticism about arithmetic. (shrink)
This was my first paper on virtue epistemology, and already highlights the connections with epistemic value and axiology which I would later develop. Although most accounts were either internalist or externalist in an exclusive sense, I suggest an inquiry-focused version through connections with the American pragmatism.
Epithets and pronominals 'en' and 'y' in French have a variety of Binding properties that are unexpected on conventional approach to Binding Theory. We argue that the linguistic variety observed cross-linguistically (and perhaps, more surprinsingly, within a single language) - derives from the morphological properties of the anaphoric element - which we claim lack number features. Epithets and pronominal like 'en' and 'y' are predicates modifying null but semantically active nouns, and must theefore refer to the Speaker. These properties, we (...) claim, explain why these elements must be employed in what we define as an Epistemic Context, and are subject to Condition C of Binding Theory. (shrink)
The standard epistemic justification for inclusiveness in political decision making is the Condorcet Jury Theorem, which states that the probability of a correct decision using majority rule increases in group size (given certain assumptions). Informally, majority rule acts as a mechanism to pool the information contained in the judgements of individual agents. I aim to extend the explanation of how groups of political agents track the truth. Before agents can pool the information, they first need to find truth-conducive information. (...) Increasing group size is also important in the initial search for truth-conducive information. (shrink)
