The main goal of this chapter is to argue that accessibilism in epistemology is incompatible with vehicle externalism in philosophy of mind. As we shall see, however, there are strong arguments for both of these positions. On the one hand, there is a compelling argument for vehicle externalism: the parity argument from Clark and Chalmers 1998. On the other hand, there is a compelling argument for accessibilism: the Moorean argument from Smithies 2012. If accessibilism is incompatible with vehicle externalism, then (...) both arguments cannot be sound. I resolve the tension by arguing that while the Moorean argument succeeds, the parity argument fails, and so vehicle externalism should be rejected on broadly epistemological grounds. (shrink)

The twin goals of this essay are: to investigate a family of cases in which the goal of guaranteed convergence to the truth is beyond our reach; and to argue that each of three strands prominent in contemporary epistemological thought has undesirable consequences when confronted with the existence of such problems. Approaches that follow Reichenbach in taking guaranteed convergence to the truth to be the characteristic virtue of good methods face a vicious closure problem. Approaches on which there is a (...) unique rational doxastic response to any given body of evidence can avoid incoherence only by rendering epistemology a curiously limited enterprise. Bayesian approaches rule out humility about one’s prospects of success in certain situations in which failure is typical. (shrink)

Perceptual Dogmatism holds that if it perceptually seems to S that p, then S has immediate prima facie justification for the belief that p. Various philosophers have made the notion of a perceptual seeming more precise by distinguishing perceptual seemings from both sensations and beliefs to accommodate a) the epistemic difference between perceptual judgments of novices and experts, and, b) the problem of the speckled hen. Using somewhat different terminology, perceptual seemings are supposed to be high-level percepts instead of low-level (...) sensations. I argue that although it is right that perceptual seemings should not be identified with sensations, they should also not be identified with percepts. There is no strong reason to assume that sensations and percepts exist as separate conscious states, and it appears therefore best to identify perceptual seemings simply with perceptual experiences interpreted as entities incorporating aspects from both sensations and percepts. However, even with this plausible identification in hand, the speckled hen will remain problematic for PD. (shrink)

For some years now, Michael Bergmann has urged a dilemma against internalist theories of epistemic justification. For reasons I explain below, some epistemologists have thought that Michael Huemer’s principle of Phenomenal Conservatism can split the horns of Bergmann’s dilemma. Bergmann has recently argued, however, that PC must inevitably, like all other internalist views, fall prey to his dilemma. In this paper, I explain the nature of Bergmann’s dilemma and his reasons for thinking that PC cannot escape it before arguing that (...) he is mistaken: PC can indeed split its horns. (shrink)

How are we to account for the epistemic contribution of our perceptual experiences to the reasonableness of our perceptual beliefs? It is well known that a conception heavily influenced by Cartesian thinking has it that experiences do not enable the experiencing subject to have direct epistemic contact with the external world; rather, they are regarded as openness to a kind of private inner realm that is interposed between the subject and the world. It turns out that if one wants to (...) insist that perceptual experiences provide epistemic reasons for perceptual beliefs about the external world as we pre-reflectively take it to be, then one should find a way of avoiding Cartesianism. Here are the two main aims of this paper: firstly, identify the premise that is doing the heavy-lifting work in the Cartesian thinking; and, secondly, formulate an adequate way of denying that premise. The adequacy I claim for my formulation of a way of denying the premise will roughly amount to this: the way I offer is not as susceptible to Cartesian traps as other apparently available ways of denying the premise are.

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay (...) rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

The paper discusses the thesis of extended belief and its implications for the possibility of extending ordinary, personal level knowledge. A common worry is that knowledge will overextend, that there will be ‘cognitive bloat’. If the subject’s standing beliefs can be realized in devices such as notebooks and smart phones, what is there to prevent the conclusion that she knows everything stored on such devices? One response to this worry is to block the move from belief to knowledge, and argue (...) that these externally stored beliefs, although reliable, do not qualify as knowledge. I argue, instead, that the fundamental problem arises at the level of belief. We prevent bloating of knowledge by preventing the bloating of belief. To do so, I argue, we need to take seriously Clark and Chalmers’ suggestion that what is distinctive of belief is its role in folk psychological explanations. Paying attention to this role shows that the usual examples, such as Otto’s notebook information, do not qualify as beliefs. To qualify, the external information would have to be much more directly connected to, and deeply integrated into, the subject’s overall system of beliefs and desires. (shrink)

Reliabilists hold that a belief is doxastically justified if and only if it is caused by a reliable process. But since such a process is one that tends to produce a high ratio of true to false beliefs, reliabilism is on the face of it applicable to binary beliefs, but not to degrees of confidence or credences. For while beliefs admit of truth or falsity, the same cannot be said of credences in general. A natural question now arises: Can reliability (...) theories of justified belief be extended or modified to account for justified credence? In this paper, I address this question. I begin by showing that, as it stands, reliabilism cannot account for justified credence. I then consider three ways in which the reliabilist may try to do so by extending or modifying her theory, but I argue that such attempts face certain problems. After that, I turn to a version of reliabilism that incorporates evidentialist elements and argue that it allows us to avoid the problems that the other theories face. If I am right, this gives reliabilists a reason, aside from those given recently by Comesaña and Goldman, to move towards such a kind of hybrid theory. (shrink)

Internalist approaches to epistemic justification are, though controversial, considered a live option in contemporary epistemology. Accordingly, if ‘active’ externalist approaches in the philosophy of mind—e.g. the extended cognition and extended mind theses—are _in principle_ incompatible with internalist approaches to justification in epistemology, then this will be an epistemological strike against, at least the _prima facie_ appeal of, active externalism. It is shown here however that, contrary to pretheoretical intuitions, neither the extended cognition _nor_ the extended mind theses are in principle (...) incompatible with two prominent versions of epistemic internalism—viz., accessibilism and mentalism. In fact, one possible diagnosis is that pretheoretical intuitions regarding the incompatibility of active externalism with epistemic internalism are symptomatic of a tacit yet incorrect identification of epistemic internalism with epistemic individualism. Thus, active externalism is not in principle incompatible with epistemic internalism per se and does not significantly restrict one’s options in epistemology. (shrink)

The distinction between the regulative (‘practical’, ‘subjective’, ‘decision-procedural’) and the theoretical (‘objective’, ‘absolute’) pertains to the aims (the desiderata) of an account of justification. This distinction began in ethics and spread to epistemology. Each of internalism, externalism, is separately forced to draw this distinction to avoid a stock, otherwise fatal, argument levelled against them by the other. Given this situation however, we may finesse much partisan conflict in epistemology by simply seeing differing accounts of justification as answering to radically distinct (...) desiderata of adequacy. We should see knowledge as answering to the theoretical desideratum of adequacy alone; and rationality as answering to the regulative desideratum of adequacy alone. Objections to this ‘Gordian’ [knot] approach to epistemology (from virtues theorists and others) are rejected. Such an approach may make for accounts that violate our ordinary language intuitions; but in developing an epistemological axiology, any such intuitions are not to the point. (shrink)

In this paper I examine the case for epistemic relativism focusing on an argument for epistemic relativism formulated (though not endorsed) by Paul Boghossian. Before examining Boghossian’s argument, however, I first examine some preliminary considerations for and against epistemic relativism.

A critical explanation of Ernest Sosa's bi-level virtue epistemology.

In their most recent co-authored work, Conee and Feldman (2008) suggest that epistemic support should be understood in terms of best explanations. Although this suggestion is plausible, Conee and Feldman admit that they have not provided the necessary details for a complete account of epistemic support. This article offers an explanationist account of epistemic support of the kind that Conee and Feldman suggest. It is argued that this account of epistemic support yields the intuitively correct results in a wide variety (...) of cases. Further, this explanationist account of epistemic support is not susceptible to objections that Lehrer (1974) and Goldman (2011) have raised for similar accounts of epistemic support. (shrink)

I advocate Time-Slice Rationality, the thesis that the relationship between two time-slices of the same person is not importantly different, for purposes of rational evaluation, from the relationship between time-slices of distinct persons. The locus of rationality, so to speak, is the time-slice rather than the temporally extended agent. This claim is motivated by consideration of puzzle cases for personal identity over time and by a very moderate form of internalism about rationality. Time-Slice Rationality conflicts with two proposed principles of (...) rationality, Conditionalization and Reflection. Conditionalization is a diachronic norm saying how your current degrees of belief should fit with your old ones, while Reflection is a norm enjoining you to defer to the degrees of belief that you expect to have in the future. But they are independently problematic and should be replaced by improved, time-slice-centric principles. Conditionalization should be replaced by a synchronic norm saying what degrees of belief you ought to have given your current evidence and Reflection should be replaced by a norm which instructs you to defer to the degrees of belief of agents you take to be experts. These replacement principles do all the work that the old principles were supposed to do while avoiding their problems. In this way, Time-Slice Rationality puts the theory of rationality on firmer foundations and yields better norms than alternative, non-time-slice-centric approaches. (shrink)

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

In common with traditional forms of epistemic internalism, epistemological disjunctivism attempts to incorporate an awareness condition on justification. Unlike traditional forms of internalism, however, epistemological disjunctivism rejects the so-called New Evil Genius thesis. In so far as epistemological disjunctivism rejects the New Evil Genius thesis, it is revisionary. -/- After explaining what epistemological disjunctivism is, and how it relates to traditional forms of epistemic internalism / externalism, I shall argue that the epistemological disjunctivist’s account of the intuitions underlying the New (...) Evil Genius thought experiment is at best incomplete. As presented, therefore, epistemological disjunctivism is unable to accommodate the core guiding intuitions of epistemic internalism. Given the stated aim of not being revisionary on this score, the view is at a dialectical disadvantage over the traditional forms of epistemic internalism the position is meant to replace. Unfortunately, therefore, at present, the impasse between internalism and externalism remains. (shrink)

This is the second in a series of two articles that serve as an introduction to recent debates about cognitive phenomenology. Cognitive phenomenology can be defined as the experience that is associated with cognitive activities, such as thinking, reasoning, and understanding. What is at issue in contemporary debates is not the existence of cognitive phenomenology, so defined, but rather its nature and theoretical role. The first article examines questions about the nature of cognitive phenomenology, while the second article explores the (...) philosophical implications of these questions for the role of consciousness in theories of intentionality, introspective self-knowledge, and knowledge of the external world.

In this paper, I present counterexamples to the evidence thesis, the thesis that S knows that p at t only if S believes that p on the basis of evidence at t. The outline of my paper is as follows. In section 1, I explain the evidence thesis and make clear what a successful counterexample to the evidence thesis will look like. In section 2, I show that instances of non-occurrent knowledge are counterexamples to the evidence thesis. At the end (...) of section 2, I consider the primary thesis of my paper — that the evidence thesis is false — to be successfully defended. In section 3, I consider three variations of the evidence thesis. The first variation restricts the evidence thesis to occurrent knowledge; the second requires for knowledge that one’s belief could be based on evidence; and the third requires for knowledge that the belief was based on evidence at a suitable prior time. The secondary thesis of this paper is that these variations are also subject to serious objections. (shrink)

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

Stewart Cohen’s New Evil Demon argument raises familiar and widely discussed concerns for reliabilist accounts of epistemic justification. A now standard response to this argument, initiated by Alvin Goldman and Ernest Sosa, involves distinguishing different notions of justification. Juan Comesaña has recently and prominently claimed that his Indexical Reliabilism (IR) offers a novel solution in this tradition. We argue, however, that Comesaña’s proposal suffers serious difficulties from the perspective of the philosophy of language. More specifically, we show that the two (...) readings of sentences involving the word ‘justified’ which are required for Comesaña’s solution to the problem are not recoverable within the two-dimensional framework of Robert Stalnaker to which he appeals. We then consider, and reject, an attempt to overcome this difficulty by appeal to a complication of the theory involving counterfactuals, and conclude the paper by sketching our own preferred solution to Cohen’s New Evil Demon.

Sometimes we get what seem to be good reasons for believing that we’ve misevaluated our evidence for a proposition P. In those cases, can we use our evidence for P itself to show that we haven’t misevaluated our evidence for P? I show why doing so appears to employ viciously circular reasoning. However, I then argue that this appearance is illusory in certain cases and that we sometimes can legitimately reason in that way. This claim sheds new light on the (...) nature of epistemic undermining and epistemic circularity. In addition, it has implications for the current debate about the epistemic significance of disagreement. An important and influential position in that debate says that disagreement with others dramatically undermines our justification for a wide range of our opinions (e.g., political, religious, moral, economic, and philosophical opinions). My view on undermining and circularity implies that this position on disagreement rests on a mistake. (shrink)

According to the bootstrapping problem, any view that allows for basic knowledge (knowledge obtained from a reliable source prior to one’s knowing that that source is reliable) is forced to accept that one can utilize a track-record argument to acquire justification for believing that one’s belief source is reliable; yet, we tend to think that acquiring justification in this way is too easy. In this paper I argue, first, that those who respond to the bootstrapping problem by denying basic knowledge (...) succumb to over-intellectualizing epistemology, and secondly, reliabilist views avoid over-intellectualization only at the expense of sanctioning bootstrapping as a benign procedure. Both of these outcomes are difficult to bear. To ward off each of these unsavory outcomes, I propose an alternative solution that draws on a distinction between two separate epistemic concepts: entitlement and justification. (shrink)

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we (...) express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed. (shrink)

In this paper I offer a theory of what makes certain influences on visual experiences by prior mental states (including desires, beliefs, moods, and fears) reduce the justificatory force of those experiences. The main idea is that experiences, like beliefs, can have rationally assessable etiologies, and when those etiologies are irrational, the experiences are epistemically downgraded.

In this paper I argue that names are predicates when they occur in the appellation position of 'called'-predications. This includes not only proper names, but all names -- including quote-names of proper names and quote-names of other words or phrases. Thus in "You can call me Al", the proper name 'Al' is a predicate. And in "You can call me 'Al'," the quote-name of 'Al' -- namely ' 'Al' ' -- is also a predicate.

This chapter develops a simple theory of introspection on which a mental state is introspectively accessible just by virtue of the fact that one is in that mental state. This theory raises two questions: first, a generalization question: which mental states are introspectively accessible; and second, an explanatory question: why are some mental states introspectively accessible, rather than others, or none at all? In response to the generalization question, I argue that a mental state is introspectively accessible if and only (...) if it is phenomenally individuated. And in response to the explanatory question, I argue that a mental state is introspectively accessible if and only if it is among the determinants of justification. This provides the basis of an argument for a phenomenal conception of justification, according to which a mental state is among the determinants of justification if and only if it is phenomenally individuated.

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 obtaining. What has been called epistemic internalism holds, as the label suggests, is that all the (...) relevant factors that determine justification must be “internal”. Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position. 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. (shrink)

According to epistemic internalism, the only facts that determine the justificational status of a belief are facts about the subject’s own mental states, like beliefs and experiences. Externalists instead hold that certain external facts, such as facts about the world or the reliability of a belief-producing mechanism, affect a belief’s justificational status. Some internalists argue that considerations about evil demon victims and brains in vats provide excellent reason to reject externalism: because these subjects are placed in epistemically unfavorable settings, externalism (...) seems unable to account for the strong intuition that these subjects’ beliefs are nonetheless justified. I think these considerations do not at all help the internalist cause. I argue that by appealing to the anti-individualistic nature of perception, it can be shown that skeptical scenarios provide no reason to prefer internalism to externalism. (shrink)

Klein’s account of epistemic justification, infinitism, supplies a novel solution to the regress problem. We argue that concentrating on the normative aspect of justification exposes a number of unpalatable consequences for infinitism, all of which warrant rejecting the position. As an intermediary step, we develop a stronger version of the ‘finite minds’ objection.

While epistemic justification is a central concern for both contemporary epistemology and philosophy of science, debates in contemporary epistemology about the nature of epistemic justification have not been discussed extensively by philosophers of science. As a step toward a coherent account of scientific justification that is informed by, and sheds light on, justificatory practices in the sciences, this paper examines one of these debates—the internalist-externalist debate—from the perspective of objective accounts of scientific evidence. In particular, we focus on Deborah Mayo’s (...) error-statistical theory of evidence because it is a paradigmatically objective theory of evidence that is strongly informed by methodological practice. We contend that from the standpoint of such an objective theory of evidence, justification in science has both externalist and internalist characteristics. In reaching this conclusion, however, we find that the terms of the contemporary debate between internalists and externalists have to be redefined to be applicable to scientific contexts. (shrink)

In his 1993 article George Bealer offers three separate arguments that are directed against the internal coherence of empiricism, specifically against Quine’s version of empiricism. One of these arguments is the starting points argument (SPA) and it is supposed to show that Quinean empiricism is incoherent. We argue here that this argument is deeply flawed, and we demonstrate how a Quinean may successfully defend his views against Bealer’s SPA. Our defense of Quinean empiricism against the SPA depends on showing (1) (...) that Bealer is, in an important sense, a foundationalist, and (2) that Quine is, in an important sense, a coherentist. Having established these two contentions we show that Bealer’s SPA begs the question against Quinean empiricists. (shrink)

An encyclopedic article on epistemic supervenience in Blackwell companion to epistemology, 2 ed.

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

I argue that you can have a priori knowledge of propositions that neither are nor appear necessarily true. You can know a priori contingent propositions that you recognize as such. This overturns a standard view in contemporary epistemology and the traditional view of the a priori, which restrict a priori knowledge to necessary truths, or at least to truths that appear necessary.

Epistemic reasons are mental states. They are not propositions or non-mental facts. The discussion proceeds as follows. Section 1 introduces the topic. Section 2 gives two concrete examples of how our topic directly affects the internalism/externalism debate in normative epistemology. Section 3 responds to an argument against the view that reasons are mental states. Section 4 presents two problems for the view that reasons are propositions. Section 5 presents two problems for the view that reasons are non-mental facts. Section 6 (...) argues that reasons are mental states. Section 7 responds to objections. (shrink)

Recent years have seen increasing attacks on the "deontological" conception (or as we call it, the guidance conception) of epistemic justification, the view that epistemology offers advice to knowers in forming beliefs responsibly. Critics challenge an important presupposition of the guidance conception: doxastic voluntarism, the view that we choose our beliefs. We assume that epistemic guidance is indispensable, and seek to answer objections to doxastic voluntarism, most prominently William Alston's. We contend that Alston falsely assumes that choice of belief requires (...) the assent to a specific propositional content. We argue that beliefs can be chosen under descriptions which do not specify their propositional content, but instead specify the mental actions by which they are formed and maintained. We argue that these actions partially constitute the beliefs and that is it in virtue of resulting from and being partially constituted by such actions that the beliefs are subject to epistemic appraisal,.

I critique Matthias Steup’s account of exercising direct voluntary control over coming to have doxastic attitudes via doxastic decisions. I show that the sort of agency Steup argues is exercised in doxastic decision-making is not sufficient for agents to exercise direct voluntary control over their doxastic attitudes. This counts against such putative decisions being the locus of direct control in doxastic agency. Finally, I briefly consider what, if any, consequences the failure of Steup’s theory of doxastic agency may have for (...) epistemic deontologism. (shrink)

I respond to John Greco’s argument that all forms of internalism in epistemology are either false or uninteresting. The paper divides into two sections. First, I explain precisely what internalists and externalists in epistemology disagree over. This puts us in a position to assess whether Greco’s argument succeeds. Second, I present Greco’s argument and offer two objections.

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)

Tradition compels me to write dissertation acknowledgements that are long, effusive, and unprofessional. Fortunately for me, I heartily endorse that tradition.

This paper defends reductionism about testimonial justification of beliefs against two influential arguments. One is the empirical argument to the effect that the reductionist justification of our trust in testimony is either circular since it relies on testimonial evidence or else there is scarce evidence in support of our trust in testimony. The other is the transcendental argument to the effect that trust in testimony is a prerequisite for the very existence of testimonial evidence since without the presumption of people’s (...) truthfulness we cannot interpret their utterances as testimony with propositional contents. This paper contends that the epistemic subject can interpret utterances as testimony with propositional contents without presupposing the credibility of testimony, and that evidence available to the normal epistemic subject can justify her trust in testimony.

Cognitive states, such as beliefs, desires and intentions, may influence how we perceive people and objects. If this is the case, are those influences worse when they occur implicitly rather than explicitly? Here we show that cognitive penetration in perception generally involves an implicit component. First, the process of influence is implicit, making us unaware that our perception is misrepresenting the world. This lack of awareness is the source of the epistemic threat raised by cognitive penetration. Second, the influencing state (...) can be implicit, though it can also be or become explicit. Being unaware of the content of the influencing state, we argue, does not make as much difference to the epistemic threat as it does to the epistemic responsibility of the agent. Implicit influencers cannot be examined for their accuracy and justification, and cannot be voluntarily accepted by the perceiver. Conscious awareness, however, is not sufficient for attributing blame to the agent. An equally important condition is the degree of control that they can exercise to change the contents that influence perception or stop their influence. Here we suggest that such control can also result from social influence, and that cognitive penetrability of perception is therefore also a social issue. (shrink)

David Enoch has argued that we can be justified in believing in irreducibly normative reasons on the grounds that such reasons are deliberatively indispensable. This deliberative indispensability argument has been attacked from a variety of angles and is generally held to be rather weak. In this paper, I argue that existing criticisms of the deliberative indispensability argument do not touch the core of Enoch's argument. Properly understood, the deliberative indispensability argument is much stronger than its critics allege. It deserves to (...) be taken seriously. (shrink)
