This paper considers the place of reasons in the metaphysics of epistemic normativity and defends a middle ground between two popular extremes in the literature. Against members of the ‘reasons first’ movement, we argue that reasons are not the sole fundamental constituents of epistemic normativity. We suggest instead that the virtue-theoretic property of competence is the key building block. To support this approach, we note that reasons must be possessed to play a role in the analysis of central epistemically normative (...) properties, and argue that the relation of possession must be analyzed in terms of competence. But while we diverge with reasons-firsters on this score, we also distance ourselves from those who deny reasons any important role in epistemology. For we maintain that possessed reasons do help to ground deontic facts in the epistemic domain (e.g., facts about what one epistemically ought to believe, may believe, or is justified in believing). Indeed, we present an argument that the possession of sufficient epistemic reasons is necessary and sufficient for propositional justification, and that proper basing on such reasons yields doxastic justification. But since possession and proper basing are themselves grounded in competence, reasons are not the end of the explanatory road: competence enables them to do their work, putting them—and us—in the middle.

In our thought, we employ rules of inference and belief-forming methods more generally. For instance, we (plausibly) employ deductive rules such as Modus Ponens, ampliative rules such as Inference to the Best Explanation, and perceptual methods that tell us to believe what perceptually appears to be the case. What explains our entitlement to employ these rules and methods? This chapter considers the motivations for broadly internalist answers to this question. It considers three such motivations—one based on simple cases, one based (...) on a general conception of epistemic responsibility, and one based on skeptical scenarios. The chapter argues that none of these motivations is successful. The first two motivations lead to forms of internalism—Extreme Method Internalism and Defense Internalism—that are too strong to be tenable. The third motivation motivates Mental Internalism (Mentalism), which does not fit with plausible accounts of entitlement. (shrink)

Timothy Williamson has argued that, unless the speech act of assertion were supposed to be governed by his so-called Knowledge Rule, one could not explain why sentences of the form "A and I do not know that A" are unassertable. This paper advances three objections against that argument, of which the first two aim to show that, even assuming that Williamson's explanandum has been properly circumscribed, his explanation would not be correct, and the third aims to show that his explanandum (...) has not been properly circumscribed.

An argument is epistemically self-defeating when either the truth of an argument’s conclusion or belief in an argument’s conclusion defeats one’s justification to believe at least one of that argument’s premises. Some extant defenses of the evidentiary value of intuition have invoked considerations of epistemic self-defeat in their defense. I argue that there is one kind of argument against intuition, an unreliability argument, which, even if epistemically self-defeating, can still imply that we are not justified in thinking intuition has evidentiary (...) value.

Internalism and externalism disagree about whether agents who are internally the same can differ in their mental states. But what is it for two agents to be internally the same? Standard formulations take agents to be internally the same in virtue of some metaphysical fact, for example, that they share intrinsic physical properties. Our aim in this chapter is to argue that such formulations should be rejected. We provide the outlines of an alternative formulation on which agents are internally the (...) same in virtue of facts about their epistemic capacities. The resulting formulation is one on which internalism and externalism are views about the extent to which an agent’s mental states can vary independently of the capacity for introspective discrimination. We suggest that this epistemic formulation of internalism and externalism picks out a substantive disagreement in philosophical theorizing about the nature of the mind. (shrink)

When members of a group doxastically disagree with each other, decisions in the group are often hard to make. The members are supposed to find an epistemic compromise. How do members of a group reach a rational epistemic compromise on a proposition when they have different (rational) credences in the proposition? I answer the question by suggesting the Fine-Grained Method of Aggregation, which is introduced in Brössel and Eder 2014 and is further developed here. I show how this method faces (...) challenges of the standard method of aggregation, Weighted Straight Averaging, in a successful way. One of the challenges concerns the fact that Weighted Straight Averaging does not respect the evidential states of agents. Another challenge arises because Weighted Straight Averaging does not account for synergetic effects. (shrink)

Abstract: On one formulation, epistemological disjunctivism is the view that our perceptual beliefs constitute knowledge when they are based on reasons that provide them with factive support. Some would argue that it is impossible to understand how perceptual knowledge is possible unless we assume that we have such reasons to support our perceptual beliefs. Some would argue that it is impossible to understand how perceptual experience could furnish us with these reasons unless we assume that the traditional view of experience (...) is mistaken. For reasons explained here, I think that the epistemological argument for metaphysical disjunctivism rests on mistaken assumptions about reasons and their rational role. Neither disjunctivist view is needed to understand how perceptual knowledge is possible. (shrink)

My topic in this paper is the nature of faith. Much of the discussion concerning the nature of faith proceeds by focussing on the relationship between faith and belief. In this paper, I explore a different approach. I suggest that we approach the question of what faith involves by focussing on the relationship between faith and action. When we have faith, we generally manifest it in how we act; we perform acts of faith: we share our secrets, rely on other’s (...) judgment, refrain from going through our partner’s emails, let our children prepare for an important exam without our interference. Religious faith, too is manifested in acts of faith: attending worship, singing the liturgy, fasting, embarking on a pilgrimage. I argue that approaching faith by way of acts of faith, reveals that faith is a complex mental state whose elements go beyond doxastic states towards particular propositions. It also involves conative states and – perhaps more surprisingly – know how. This has consequences for the epistemology of faith: the role of testimony and experts, the importance of practices, and what we should make of Pascal’s advice for how to acquire faith. (shrink)

Epistemologists have shown increased interest in the epistemic significance of disagreement, and in particular, in whether there is a rational requirement concerning belief revision in the face of peer disagreement. This article examines some of the general issues discussed by epistemologists, and then considers how they may or may not apply to the case of religious disagreement, both within religious traditions and between religious (and non-religious) views.

This paper argues that the innovation of an ordering source parameter in the standard Lewis-Kratzer semantics for modals was a mistake, at least for English auxiliaries like ‘ought’, and that a simpler dyadic semantics (as proposed in my earlier work) provides a superior account of normative uses of modals. I programmatically investigate problems arising from (i) instrumental conditionals, (ii) gradability and “weak necessity”, (iii) information-sensitivity, and (iv) conflicts, and show how the simpler semantics provides intuitive solutions given three basic moves: (...) (1) an end-relational analysis of normative modality, (2) a “most” analysis of “weak necessity”, and (3) well-motivated appeals to pragmatics. I conclude with metasemantic observations about the desiderata for a semantics for ‘ought’. (shrink)

A disjunctivist conception of acting for reasons is introduced by way of showing that a view of acting for reasons must give a place to knowledge. Two principal claims are made. 1. This conception has a rôle analogous to that of the disjunctive conception that John McDowell recommends in thinking about perception; and when the two disjunctivist conceptions are treated as counterparts, they can be shown to have work to do in combination. 2. This conception of acting for reasons safeguards (...) the connection between considerations that move us to act in particular ways and considerations that favour our acting in particular ways.

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.

In this paper [submitted in 2008] I discuss the relation between truth and assertion. But the paper was never published, because the journal did not start (I don't know whether it started with another name and I wish all the best for this enterprise). After a while, I realized that what I had written was unclear and I tried to re-write with more details for "Agora filosofica". In this new paper I discuss in detail Kripke's example presented as a case (...) against Donnellan's distinction, and I claim that one of the two dialogues breaks Grice's Cooperation principle (and,in general, the charity principle).

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief. (shrink)

To what extent should we trust our natural instincts about knowledge? The question has special urgency for epistemologists who want to draw evidential support for their theories from certain intuitive epistemic assessments while discounting others as misleading. This paper focuses on the viability of endorsing the legitimacy of Gettier intuitions while resisting the intuitive pull of skepticism – a combination of moves that most mainstream epistemologists find appealing. Awkwardly enough, the “good” Gettier intuitions and the “bad” skeptical intuitions seem to (...) be equally strong. This chapter argues that it is not a coincidence that these two types of intuition register with equal force: they are generated by a common mechanism. However, the input to this mechanism is interestingly different in the two types of case, and different in a way that can support the mainstream view that Gettier cases tell us something about knowledge where skeptical intuitions involve systematic error.

This paper argues that attitudinal objects, entities of the sort of John's judgment, John's thought, and John's claim, should play the role of propositions, as the cognitive products of cognitive acts, not the acts themselves.

Swear words are highly colloquial expressions that have the capacity to signal the speaker's affective states, i.e., to display the speaker's feelings with respect to a certain stimulus. For this reason, swear words are often called 'expressives'. Which linguistic mechanisms allow swear words display affective states, and, more importantly, how can such 'affective content' be characterized in a theory of meaning? Even though research on expressive meaning has produced models that integrate the affective aspects of swear words in a compositional (...) framework, there is extensive evidence that swear words cannot be assigned a single or stable affective interpretation across contexts. For example, even though expletive adjectives (e.g., 'damn'), particularistic insults (e.g., 'bastard') and slurs (e.g., 'wop') typically express (and elicit) negatively valenced affective states, they can also be interpreted positively in some contexts. Thus, inspired in recent developments in formal sociolinguistics, I propose an 'indexical' approach to affective meaning. Under this approach, an affective expression is associated with a set of affective qualities, anyone of which may emerge at a given context depending on the interpreter's prior assumptions about the speaker's affective states and/or relation with the target of the swear word. To define this set, also called 'indexical field', I will use the dimensions pleasure, arousal and dominance, standardly employed in cognitive psychology to characterize and measure affective episodes. In this dissertation, thus, the affective meaning of an expression is given by the set of affective states it typically conveys within a linguistic community, but its interpretation at a given context is established by taking into account the interpreter's prior assumptions about the speaker's affective states and/or attitudes with respect to the target of the affective expression.

The distinction between propositional and doxastic justification is normally applied to belief. The goal of this paper is to apply the distinction to faith and hope. Before doing so, I discuss the nature of faith and hope, and how they contrast with belief—belief has no essential conative component, whereas faith and hope essentially involve the conative. I discuss implications this has for evaluating faith and hope, and apply this to the propositional/doxastic distinction. There are two key upshots. One, bringing in (...) faith and hope makes salient additional normative categories, including the way the distinction between epistemic and practical justification interacts with the distinction between propositional and doxastic justification. Two, a paradigm example of propositional without doxastic justification is a belief that is evidentially supported but based on wishful thinking. Surprisingly, parallel cases of faith and hope may actually enjoy both propositional and doxastic justification. I conclude by exploring what it might look like for faith and hope to have propositional justification without doxastic justification. (shrink)

What is the connection between justification and truth in moral epistemology? The primary goal of this paper is to argue that you cannot have justified false beliefs about your own moral obligations. The secondary goal is to explain why not. Some epistemologists embrace a global truth-connection in epistemology, according to which epistemic justification is always factive. In contrast, I endorse a local truth-connection in moral epistemology, which says that epistemic justification is factive when it concerns your own moral obligations. To (...) explain this, I appeal to a version of moral rationalism, which says there are necessary truths about morality that everyone has a priori justification to believe. (shrink)

§§3-4 of the Begriffsschrift present Frege’s objections to a dominant if murky nineteenth-century semantic picture. I sketch a minimalist variant of the pre-Fregean picture which escapes Frege’s criticisms by positing a thin notion of semantic content which then interacts with a multiplicity of kinds of truth to account for phenomena such as modality. After exploring several ways in which we can understand the existence of multiple truth properties, I discuss the roles of pointwise and setwise truth properties in modal logic. (...) I argue that thinking of supertruth and determinate truth as setwise truth properties allows an understanding of supervaluationist approaches to vagueness which escapes both Williamson’s objections to and a needless metalinguistic orientation of traditional supervaluationism.

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). 3. The (...) rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. -/- How can there be such practices? This paper offers an answer to that question. (shrink)

forthcoming in reisner and steglich-peterson, eds., Reasons for Belief If I believe, for no good reason, that P and I infer (correctly) from this that Q, I don’t think we want to say that I ‘have’ P as evidence for Q. Only things that I believe (or could believe) rationally, or perhaps, with justification, count as part of the evidence that I have. It seems to me that this is a good reason to include an epistemic acceptability constraint on evidence (...) possessed…1 It is a truism that adopting an unjustified belief does not put you in a better evidential position with respect to believing its consequences. This truism has led many philosophers to assume that there must, at a minimum, be a justification condition (and perhaps even a knowledge condition) on what it takes to count as having evidence. This is the best (or only) possible explanation of the truism, these philosophers have believed. This paper explores an alternative explanation for the truism. According to the alternative explanation that I will offer, unjustified beliefs do not put you in a better evidential position with respect to believing their consequences because any evidence you have in virtue of having an unjustified belief is guaranteed to be defeated. Since the lack of justification for a belief guarantees its defeat, I will suggest, we don't need to postulate a special justification condition (much less a knowledge condition) on what it takes to count as having evidence. Why is this important? It is important because the assumption that there must be a justification condition (or perhaps a knowledge condition) on what it takes to count as having evidence places a high bar on what it takes to have evidence - such a high bar that it is difficult to see how this bar could be met in the case of basic, perceptually justified beliefs. As a result, the high bar set by this condition plays a fundamental role, I will claim, in central features of a core dialectic from the epistemology of basic perceptual belief which plays a central role in the debates between internalism and externalism, foundationalism and coherentism, and rationalism and empiricism..

Two different versions of epistemological disjunctivism have recently been upheld in the literature: a traditional, Justified True Belief Epistemological Disjunctivism (JTBED) and a Knowledge First Epistemological Disjunctivism (KFED). JTBED holds that factive reasons of the form “S sees that p” provide the rational support in virtue of which one has perceptual knowledge, while KFED holds that factive reasons of the form “S sees that p” just are ways of knowing that p which additionally provide justification for believing that p. We (...) argue that both accounts remain ultimately unsatisfactory. JTBED faces two formidable problems: first, it cannot account for animal knowledge, and, second, it does not offer a satisfactory account of how we access factive reasons. Although KFED can solve these two problems, it has some problems of its own. While intuitively knowledge is logically stronger than justified belief, on KFED it turns out to be weaker: knowledge does not entail justified belief, but justified belief does entail knowledge. Nevertheless, disjunctivists are right on at least a couple of points: we standardly justify our perceptual beliefs by appealing to factive reasons such as seeing that p and so factive reasons ought to play some role in our theory of justification. In addition, KFED’s account of our access to factive reasons also is spot on. Rather than going disjunctivist, these insights can be suitably incorporated into a Knowledge First Virtue Epistemology (KFVE). (shrink)

At the heart of the Bayesianism is a rule, Conditionalization, which tells us how to update our beliefs. Typical formulations of this rule are underspecified. This paper considers how, exactly, this rule should be formulated. It focuses on three issues: when a subject’s evidence is received, whether the rule prescribes sequential or interval updates, and whether the rule is narrow or wide scope. After examining these issues, it argues that there are two distinct and equally viable versions of Conditionalization to (...) choose from. And which version we choose has interesting ramifications, bearing on issues such as whether Conditionalization can handle continuous evidence, and whether Jeffrey Conditionalization is really a generalization of Conditionalization.

Metaethical debunking arguments often conclude that no moral belief is epistemically justified. Early versions of such arguments largely relied on metaphors and analogies and left the epistemology of debunking underspecified. Debunkers have since come to take on substantial and broad-ranging epistemological commitments. The plausibility of metaethical debunking has thereby become entangled in thorny epistemological issues. In this thesis, I provide a critical yet sympathetic evaluation of the prospects and challenges facing such arguments in light of this development. In doing so, (...) I address the following central question: how could genealogical information undermine the epistemic justification of moral beliefs? In Part I, I begin answering the central question by extracting explicit and implicit epistemic principles from three popular debunking arguments. These arguments, due to Gilbert Harman, Richard Joyce, and Sharon Street, generate principles concerning ontological parsimony, explanatory dispensability, epistemic insensitivity, lack of epistemic safety, unexplained reliability, epistemic coincidences, and explanatory constraints on rational belief. Having set out the principles tasked with explaining how genealogical information undermines, Part II of the thesis seeks to evaluate whether debunking arguments built on them succeed. To this end, I consider two types of challenges faced by such arguments. First, there are strategies that attempt to block global moral debunking arguments. I argue that one popular such strategy, the so-called ‘third-factor strategy’, has been misunderstood. When understood correctly, it is of no help in answering debunking arguments. I then flesh out an alternative and more promising strategy for blocking such arguments. I then turn to internal challenges facing debunkers, particularly those who rely on ‘explanationist’ principles. I argue that explanationist debunking arguments, as well as most others, fall prey to one or more of four internal challenges: the implausibility of first-order epistemic principles, the threat of overgeneralization, the threat of self-defeat, and the need for costly metaepistemic commitments. I conclude that current debunking arguments fail to establish that no moral belief is justified. By analyzing why existing arguments fail, I develop two conditions of adequacy that debunkers must satisfy in order to navigate the internal challenges successfully. I end by suggesting future directions that debunkers should pursue to rehabilitate the prospects for global moral debunking arguments. (shrink)

Epistemic justification has been widely accepted as both a gradational and relational notion. Given those properties, a natural thought is to take degrees of epistemic justification to be probabilities. In this paper, we present a simple Bayesian framework for justification. In the first part, after putting the model in an evidentialist form, we distinguish different senses of “being evidence for” and “confirming”. Next, we argue that this conception should accommodate the two relevant kinds of qualitative confirmation or evidential support. In (...) the second part of the paper, we discuss the claim that this view is unable to satisfy the modified version of the conjunction closure for beliefs in probabilistically independent propositions. We defend that the underlying assumption on which this objection depends leads to an improper reading of the concept of epistemic probability. After providing a better interpretation of it, we put forward a rationale, which is based on the notion of conditional uncertainty, in support of a more plausible and restricted version of the closure of justification under conjunction.

This paper targets a series of potential issues for the discussion of, and modal resolution to, the alethic paradoxes advanced by Scharp (2013). I proffer four novel extensions of the theory, and detail five issues that the theory faces.

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

This essay defends an epistemicist response to the phenomenon of vagueness concerning moral terms. I outline a traditional model of - and then two novel approaches to - epistemicism about moral predicates, and I demonstrate how the foregoing are able to provide robust explanations of the source of moral, as epistemic, indeterminacy. The first approach to moral epistemicism concerns the extensions of moral predicates, as witnessed by the non-transitivity of a value-theoretic sorites paradox. The second approach to moral epistemicism is (...) induced by the status of moral dilemmas in the epistemic interpretation of two-dimensional semantics. I examine the philosophical significance of the foregoing, and compare the proposal to those of ethical expressivism, constructivism, and scalar act-consequentialism. Finally, I examine the status of moral relativism in light of the epistemicist models of moral vagueness developed in the paper. (shrink)

This essay aims to provide a modal logic for rational intuition. Similarly to treatments of the property of knowledge in epistemic logic, I argue that rational intuition can be codified by a modal operator governed by the modal $\mu$-calculus. Via correspondence results between fixed point modal propositional logic and the bisimulation-invariant fragment of monadic second-order logic, a precise translation can then be provided between the notion of 'intuition-of', i.e., the cognitive phenomenal properties of thoughts, and the modal operators regimenting the (...) notion of 'intuition-that'. I argue that intuition-that can further be shown to entrain conceptual elucidation, by way of figuring as a dynamic-interpretational modality which induces the reinterpretation of both domains of quantification and the intensions and hyperintensions of mathematical concepts that are formalizable in monadic first- and second-order formal languages. Hyperintensionality is countenanced via a topic-sensitive epistemic two-dimensional truthmaker semantics. (shrink)

This paper aims to contribute to the analysis of the nature of mathematical modality and hyperintensionality, and to the applications of the latter to absolute decidability. Rather than countenancing the interpretational type of mathematical modality as a primitive, I argue that the interpretational type of mathematical modality is a species of epistemic modality. I argue, then, that the framework of two-dimensional semantics ought to be applied to the mathematical setting. The framework permits of a formally precise account of the priority (...) and relation between epistemic mathematical modality and metaphysical mathematical modality. The discrepancy between the modal systems governing the parameters in the two-dimensional intensional setting provides an explanation of the difference between the metaphysical possibility of absolute decidability and our knowledge thereof. I also advance a topic-sensitive epistemic two-dimensional truthmaker semantics, if hyperintensional approaches are to be preferred to possible worlds semantics. I examine the relation between two-dimensional hyperintensional states and epistemic set theory, providing two-dimensional hyperintensional formalizations of the modal logic of ZFC, large cardinal axioms, $\Omega$-logic, and the Epistemic Church-Turing Thesis.

I deal here with one of Boghossian’s arguments against content externalism, related to ourinferential rationality(to use his term). According to his reasoning, the apriority of our logical abilities is inconsistent with certain externalist assumptions. Nevertheless, the problem constitutes an important challenge foranytheory of content, not just for externalism. Furthermore, when we examine what internalists may propose to solve the problem, we see that externalists have at their disposal a more promising repertoire of possible replies than internalists. In that sense, insofar (...) as Boghossian’s scenario is relevant to the debate externalism/internalism, it can be seen (against Boghossian’s original intention) as providing additional evidence for content externalism.

An influential account or group belief analyzes it as a form of joint commitment by group members. In spite of its popularity, the account faces daunting objections. I consider and reply to two of them. The first, due to Jennifer Lackey, is that the joint commitment account fails as an account of group belief since it cannot distinguish group beliefs from group lies and bullshit. The second is that the joint commitment account fails because it makes group belief voluntary, whereas (...) genuine belief is involuntary. I propose an amendment to the basic joint commitment account which offers a unified reply to both objections. Although my novel account of group belief departs from the basic joint commitment account, it retains its spirit. The account entails that genuine group belief is much rarer than proponents of the joint commitment account have hitherto realized. (shrink)

While there is no shortage of philosophical literature discussing knowledge by acquaintance, there is a surprising dearth of work about theories of epistemic justification based on direct acquaintance. This paper explores a basic framework for a thoroughly general account of epistemic justification by acquaintance. I argue that this approach to epistemic justification satisfies two importance aspects of justification. After sketching how the acquaintance approach can meet both objective and subjective aspects for epistemic justification, I will outline how this general account (...) of justification by acquaintance can be applied to the analysis of justification for many types of beliefs. Finally, some of the objections to the acquaintance approach will be considered and answered. (shrink)

This paper discusses practical akrasia from the perspective of the sophisticated form of moral subjectivism that can be derived from Nuno Venturinha’s remarks on moral matters.

Duncan Pritchard has recently defended a view he calls ‘epistemological disjunctivism’, largely inspired by John McDowell. I argue that Pritchard is right to associate the view with McDowell, and that McDowell’s ‘inference-blocking’ argument against the sceptic succeeds only if epistemological disjunctivism is accepted. However, Pritchard also recognises that epistemological disjunctivism appears to conflict with our belief that genuine and illusory experiences are indistinguishable (the ‘distinguishability problem’). Since the indistinguishability of experiences is the antecedent in the inference McDowell intends to block, (...) I suggest that his argument rests on an inconsistent set of premises. In support of this, I show that Pritchard’s response to the distinguishability problem is incompatible with the conclusion of the ‘inference-blocking’ argument, and that the response available in McDowell’s work relies on a mistaken conception of fallibility. Either McDowell must deny the sceptic’s premise that perceptual experiences are indistinguishable, or he must give up his conclusion that perceptual warrant can be indefeasible. (shrink)

Denying the conclusion of a valid argument is not generally permissible if one suspends on one premise of the argument and believes the other premise. This can happen when one’s only critique of an argument is to undermine one premise. There is incoherence there. Here I examine how this is relevant to the debate on evolutionary debunking of our moral knowledge. I argue that one significant line of response to the debunker is unsuccessful: merely undermining the debunker’s empirical claim. It (...) is not rational to respond this way and believe one has moral knowledge. First I present evidence that prominent critics of the debunking argument merely undermine the debunker’s empirical claim. Then I argue for two premises: merely undermining a premise can only justify a middling amount of doubt towards the premise and we should have no more doubt about the conclusion of a valid argument than we do about the premises. Implications of the argument are explored. (shrink)

What is scientific progress? This paper advances an interpretation of this question, and an account that serves to answer it. Roughly, the question is here understood to concern what type of cognitive change with respect to a topic X constitutes a scientific improvement with respect to X. The answer explored in the paper is that the requisite type of cognitive change occurs when scientific results are made publicly available so as to make it possible for anyone to increase their understanding (...) of X. This account is briefly compared to two rival accounts of scientific progress, based respectively on increasing truthlikeness and accumulating knowledge, and is argued to be preferable to both.

Among epistemologists, it is not uncommon to relate various forms of epistemic luck to the vexed debate between internalists and externalists. But there are many internalism/externalism debates in epistemology, and it is not always clear how these debates relate to each other. In the present paper I investigate the relation between epistemic luck and prominent internalist and externalist accounts of epistemic justification. I argue that the dichotomy between internalist and externalist concepts of justification can be characterized in terms of epistemic (...) luck. Whereas externalist theories of justification are incompatible with veritic luck but not with reflective luck, the converse is true for internalist theories of justification. These results are found to explain and cohere with some recent findings from elsewhere in epistemology, and support a surprising picture of justification, on which internalism and externalism are complementary rather than contradictory positions.

In this paper, I spell out and argue for a new epistemic theory of argumentation. Contrary to extant views, this theory is compatible with a pluralistic framework on argumentation, where the norms governing argumentation depend on the aim with which we engage in the practice. A domain of specifically epistemic argumentation is singled out, and I argue based on recent findings in modal epistemology that this domain is governed by the modal norm of safety; where a belief is safe just (...) in case it is produced by a method that would not easily produce a false belief. While this criterion is well-known and uncontroversial in epistemology, it has hitherto not been applied to epistemic theories of argumentation. I show that the norm allows for a novel and superior perspective of the relevance of the persistent interlocutor in argumentation theory, and on the relation between dialectical and epistemic norms more generally.

Traditionally, epistemologists have held that only truth-related factors matter in the question of whether a subject can be said to know a proposition. Various philosophers have recently departed from this doctrine by claiming that the answer to this question also depends on practical concerns. They take this move to be warranted by the fact that people’s knowledge attributions appear sensitive to contextual variation, in particular variation due to differing stakes. This paper proposes an alternative explanation of the aforementioned fact, one (...) that allows us to stick to the orthodoxy. The alternative applies the conceptual spaces approach to the concept of knowledge. With knowledge conceived of spatially, the variability in knowledge attributions follows from recent work on identity, according to which our standards for judging things (including concepts) to be identical are context-dependent. On the proposal to be made, it depends on what is at stake in a context whether it is worth distinguishing between knowing and being at least close to knowing. (shrink)

This paper motivates an account of knowledge as a social kind, following a cue by Edward Craig, which captures two major insights behind social and feminist epistemologies, in particular our epistemic interdependence concerning knowledge and the role of social regulative practices in understanding knowledge.

It is argued, on the basis of new counterexamples, that neither knowledge nor epistemic justification (or “epistemic rationality”) can reasonably be thought to be closed under logical implication. The argument includes an attempt to reconcile the fundamental intuitions of the opposing parties in the debate.

The use of ‘S knows p’ varies from context to context. The contextualist theories of Cohen, Lewis, and DeRose explain this variation in terms of semantic hypotheses: ‘S knows p’ is indexical in meaning, referring to features of the ascriber’s context like salience, interests, and stakes. The linguistic evidence against contextualism is extensive. I maintain that the contextual variation of knowledge claims results from pragmatic factors. One is variable strictness :395–438, 2007). In addition to its strict use, ‘S knows p’ (...) may be used loosely to implicate that S is close enough to knowing p for contextually indicated purposes. Here I explore another variable: belief about what is known. This factor is pragmatic rather than semantic in that it affects the use of ‘S knows p’ without affecting its truth conditions. While variation in strictness accounts for the variation in the bank, parking, and some lottery cases, variation in belief accounts for the variation in other lottery cases and the epistemology cases. Along the way, I sketch an insensitive invariantist semantics that is strict but non-skeptical, and show how it works with these pragmatic factors. (shrink)
