In this note, I discuss David Enoch's influential deliberative indispensability argument for metanormative realism, and contend that the argument fails. In doing so, I uncover an important disanalogy between explanatory indispensability arguments and deliberative indispensability arguments, one that explains how we could accept the former without accepting the latter.

Philosophical arguments usually are and nearly always should be abductive. Across many areas, philosophers are starting to recognize that often the best we can do in theorizing some phenomena is put forward our best overall account of it, warts and all. This is especially true in esoteric areas like logic, aesthetics, mathematics, and morality where the data to be explained is often based in our stubborn intuitions. -/- While this methodological shift is welcome, it's not without problems. Abductive arguments involve (...) significant theoretical resources which themselves can be part of what's being disputed. This means that we will sometimes find otherwise good arguments which suggest their own grounds are problematic. In particular, sometimes revising our beliefs on the basis of such an argument can undermine the very justification we used in that argument. -/- This feature, which I'll call self-effacingness, occurs most dramatically in arguments against our standing views on the esoteric subject matters mentioned above: logic, mathematics, aesthetics, and morality. This is because these subject matters all play a role in how we reason abductively. This isn't an idle fact; we can resist some challenges to our standing beliefs about these subject matters exactly because the challenges are self-effacing. The self-effacing character of certain arguments is thus both a benefit and limitation of the abductive turn and deserves serious attention. I aim to give it the attention it deserves. (shrink)

Few philosophers believe that G. E. Moore's notorious proof of an external world can give us justification to believe that skepticism about perceptual beliefs is false. The most prominent explanation of what is wrong with Moore's proof—as well as some structurally similar anti-skeptical arguments—centers on conservatism: roughly, the view that someone can acquire a justified belief that p on the basis of E only if he has p-independent justification to believe that all of the skeptical hypotheses that undermine the support (...) lent by E to p are false. In this paper I argue that conservatism does not make trouble for Moore's proof. I do this by setting up a dilemma concerning the notion of "justification to believe" that figures in conservatism. On one understanding of justification to believe, conservatism is subject to obvious counterexamples. On another understanding of justification to believe, conservatism is consistent with Moore's "proof conferring justification upon its conclusion. Since these two understandings exhaust the logical space, the conservative indictment of Mooreanism fails. (shrink)

I argue that what evidence an agent has does not supervene on how she currently is. Agents do not always have to infer what the past was like from how things currently seem; sometimes the facts about the past are retained pieces of evidence that can be the start of reasoning. The main argument is a variant on Frank Arntzenius’s Shangri La example, an example that is often used to motivate the thought that evidence does supervene on current features.

A new reading of G.E. Moore's ‘Proof of an External World’ is offered, on which the Proof is understood as a unique and essential part of an anti-sceptical strategy that Moore worked out early in his career and developed in various forms, from 1909 until his death in 1958. I begin by ignoring the Proof and by developing a reading of Moore's broader response to scepticism. The bulk of the article is then devoted to understanding what role the Proof plays (...) in Moore's strategy, and how that role is played. (shrink)

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori ; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the (...) naturalist’s commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

I give a brief overview of Albert Casullo’s Essays on A Priori Knowledge and Justification (2012), followed by a summary of his diagnostic framework for evaluating accounts of a priori knowledge and a priori justification. I then discuss Casullo’s strategy for countering deficiency arguments against empiricism. A deficiency argument against empiricism can be countered by mounting a parallel argument against moderate rationalism that shows moderate rationalism to be defective in a similar way. I argue that a particular deficiency argument put (...) forth by George Bealer in “The Incoherence of Empiricism” (1992) can withstand a parallel challenge mounted by Casullo (2012, Ch.6). -/- I then consider Casullo’s preferred analysis of the concept of a priori justification, which identifies a belief’s being justified by some nonexperiential source as the feature by virtue of which it is justified a priori. On the analysis, an apriori-justfied belief that is justified to a degree that is sufficient for knowledge is not taken to be empirically indefeasible. I argue that Casullo could avail himself of an empirical indefeasibility requirement that is consistent with his minimal and fallibilist conception of a priori knowledge. Doing so would capture a feature of the concept of a priori knowledge that is of particular interest and significance. (shrink)

For a putative knower S and a proposition P , two types of skepticism can be distinguished, depending on the conclusions they draw: outer skepticism , which concludes that S does not know that P , and inner skepticism , which concludes that S does not know whether P . This paper begins by showing that outer skepticism has undesirable consequences because that S does not know that P presupposes P , and inner skepticism does not have this undesirable consequence (...) since that S does not know whether P does not presuppose P . We indicate that the two types of skepticism aim to different loci of doubts: while outer skepticism doubts whether we can gain an epistemic warrant for the actuality, inner skepticism doubts whether we can gain epistemic identification of the actuality. It is further indicated that responses to skepticism from externalist theories, as well as from fallibilist internalist theories, can only respond to outer skepticism but not to inner skepticism.

I argue that if we allow that Moore’s Method, which involves taking an ordinary knowledge claim to support a substantive metaphysical conclusion, can be used to support Moore’s proof an external world, then we should accept that Moore’s Method can be used to support a variety of incompatible metaphysical conclusions. I shall refer to this as “the problem of many proofs”. The problem of many proofs, I claim, stems from the theory-ladenness of perception. I shall argue further that this plethora (...) of proofs for incompatible positions leads to a darker form of skepticism, one which maintains that each of the dogmatic views is probably false. We will conclude by considering various ways a Moorean might respond to these difficulties. (shrink)

Apparently, aiming to comply with the norm ‘Believe that P if and only if the proposition that P is true’ can hardly differ from aiming to comply with the norm ‘Believe that P if and only if the proposition that P is epistemically justified’. So one may be tempted to agree with Richard Rorty that the distinction between truth and justification is pragmatically useless because it cannot make any difference ‘when the question is about what I should believe now’. I (...) resist this conclusion by arguing that the distinction between truth and justification is pragmatically useful even if the two properties are indeed normatively coincident. The argument I offer turns on the claim that truth plays an explanatory role that justification is inherently incapable of playing. However, my contention is not just that the distinction between truth and justification is pragmatically useful because truth is a bona fide explanatory notion. It is that the distinction between truth and justification is pragmatically useful because the realization that the former plays an explanatory role that the latter is inherently incapable of playing gives access to reasons which would otherwise escape our attention. If truth is a bona fide explanatory notion, the distinction between truth and justification is pragmatically useful because it is precisely when the question is about what I should believe now that attending to such a distinction will often make a difference – and it will make a difference even if the two properties are in fact normatively coincident.

Crispin Wright’s “Unified Strategy” for addressing some familiar sceptical paradoxes exploits a subtle distinction between two different ways in which we can be related to a proposition: (full-blown) belief and (mere) acceptance. The importance of the distinction for his strategy stems from his conviction that we cannot acquire any kind of evidence, either empirical or a priori, for the “cornerstones” of our cognitive projects, i.e., for those basic presuppositions of our inquiries that we must be warranted to endorse if we (...) are to claim warrant for any of the beliefs formed as a result of such inquiries: regarding the idea of a non-evidential warrant to believe a proposition as a kind of “conceptual solecism”, he doesn’t set himself the task of showing that we are evidentially warranted to believe such presuppositions, but only that of showing that we are non-evidentially warranted to accept them. In the present paper, I argue that such choice involves a fatal departure from a basic principle governing doxastic commitment—a principle that requires that we regard cornerstones propositions as propositions we are rationally committed to believe, not just entitled to accept. I press the point by presenting the Acceptance Argument, a sceptical paradox whose consideration leads to the conclusion that the Unified Strategy is caught between the Scylla of incoherently invoking a rather dubious form of epistemic alchemy and the Charybdis of placing an unexpected and apparently ad hoc restriction on the doxastic commitments we undertake by believing the things we believe. My final suggestion is that the Unified Strategy might be spared this dilemma only by undergoing a rather radical revision—a revision that would require setting aside the distinction between belief and acceptance to re-conceptualise its goal unabashedly in terms of (non-evidentially) warranted belief.

Theoria, Volume 87, Issue 5, Page 1222-1249, October 2021.

In the discussion of certainties, or ‘hinges’, in Wittgenstein’s On Certainty some of the examples that Wittgenstein uses are religious ones. He remarks on how a child might be raised so that they ‘swallow down’ belief in God (§107) and in discussing the role of persuasion in disagreements he asks us to think of the case of missionaries converting natives (§612). In the past decade Duncan Pritchard has made a case for an account of the rationality of religious belief inspired (...) by On Certainty which he calls ‘quasi-fideism’. Pritchard argues that religious beliefs are just like ordinary non-religious beliefs in presupposing fundamental arational commitments. However, Modesto Gómez-Alonso has recently argued that there are significant differences between the kinds of ‘hinges’ discussed in Wittgenstein’s On Certainty and religious beliefs such that we should expect an account of rationality in religion to be quite different to the account of rational practices and their foundations that we find in Wittgenstein’s work. Fundamental religious commitments are, as Wittgenstein said, in the foreground of the religious believer’s life whereas hinge commitments are said to be in the background. People are passionately committed to their religious beliefs but it is not at all clear that people are passionately committed to hinges such as that ‘I have two hands’. I argue here that although there are differences between religious beliefs and many of the hinge-commitments discussed in On Certainty religious beliefs are nonetheless hinge-like. Gómez-Alonso’s criticisms of Pritchard mischaracterise his views and something like Pritchard’s quasi-fideism is the correct account of the rationality of religious belief. (shrink)

In this paper, I first introduce the main motivations for the internalism/externalism dichotomy in epistemology and explore different accounts of epistemic justification, mostly externalist, arising from Dretske’s relevant alternatives theory of knowledge, namely the reliabilism of Goldman and Nozick, the contextualism of Cohen and DeRose, which is governed by fallibilist standards, and Lewis’ version of contextualism, to which infallibilist standards apply. I then argue that Wittgenstein critically anticipates many of these strategies and tries to avoid such a dichotomy by assuming (...) a form of infallibilism which is neither internal nor external. After introducing the idea of a Wittgensteinian hinge epistemology and how it responds to the problem of epistemic justification and to the particular challenge posed by radical scepticism, I defend the view that infallibility is logically unavoidable when we realize that we are always trapped in one language-game or another, even if we constantly switch between language-games.

Hinge epistemology and Bayesianism are two prominent approaches in contemporary epistemology, but the relationship between these approaches has not been systematically studied. This paper formalizes the central commitments of hinge epistemology in a Bayesian framework and argues for the following two theses: (1) many of the types of claims that are treated as paradigmatic hinges in the hinge epistemology literature, such as the claim that there exists an external world of physical objects, are not capable of enabling rational inquiry, even (...) though this is typically regarded as a central property of hinges; (2) the standard Bayesian story of how rational inquiry proceeds is incorrect or at best incomplete. (shrink)

In a series of papers, Crispin Wright has proposed a number of arguments to show that what makes one’s perceptual experience confer justification on the beliefs it gives rise to includes having independent, non-evidential warrant to believe the kind of presuppositions that the skeptic highlights. It has been objected that such arguments at most show that entitlement has a pragmatic character. While sympathizing with this objection, I will argue in this paper that the kind of considerations that Wright adduces in (...) support of the entitlement thesis can nevertheless bear on the epistemic status of cornerstone beliefs, though not in the way envisaged by Wright himself. To show this, I shall make use of the thesis of pragmatic encroachment arguing that, in addition to its practical stakes, the epistemic stakes of a belief are also relevant to its epistemic status. The consequences of the claim will then be explored for the question of the epistemic status of cornerstone beliefs which seem to show that, pace Wright, such beliefs can, after all, be evidentially warranted. (shrink)

Crispin Wright has advanced a number of arguments to show that, in addition to evidential warrant, we have a species of non-evidential warrant, namely, “entitlement”, which forms the basis of a particular view of the architecture of perceptual justification known as “epistemic conservatism”. It is widely known, however, that Wright's conservative view is beset by a number of problems. In this article, I shall argue that the kind of warrant that emerges from Wright's account is not the standard truth-conducive justification, (...) but what is known as the deontological conception of justification. It will be argued that the deontological justification has features that make it a better candidate for representing a conservative architecture. These results will be reinforced by showing how the deontological framework can make better sense of a recent theory of justified belief that takes its inspiration from Wright's conservative account. Thus understood, we may see the liberalism–conservatism controversy as actually an extension of the older debate over which conception of justification, truth-conducive or deontological, can best represent the epistemic status of our belief-forming practices.

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false. (shrink)

As I use the term, ‘entitlement’ is any warrant one has by default—i.e. without acquiring it. Some philosophers not only affirm the existence of entitlement, but also give it a crucial role in the justification of our perceptual beliefs. These philosophers affirm the Entitlement Thesis: An essential part of what makes our perceptual beliefs justified is our entitlement to the proposition that I am not a brain-in-a-vat. Crispin Wright, Stewart Cohen, and Roger White are among those who endorse this controversial (...) claim. In this paper, I argue that the Entitlement Thesis is false. (shrink)

Perceptual dogmatism holds that if it perceptually seems to S that P, then S thereby has prima facie perceptual justification for P. But suppose Wishful Willy's desire for gold cognitively penetrates his perceptual experience and makes it seem to him that the yellow object is a gold nugget. Intuitively, his desire-penetrated seeming can't provide him with prima facie justification for thinking that the object is gold. If this intuitive response is correct, dogmatists have a problem. But if dogmatists have a (...) problem, you do too (well, most of you anyway). Reliabilists have denounced dogmatism's cognitive penetration problems, but they have problems with cognitive penetration that are even worse. (shrink)

Recent discussion of Vogel-style “bootstrapping” scenarios suggests that they provide counterexamples to a wide variety of epistemological theories. Yet it remains unclear why it’s bad for a theory to permit bootstrapping, or even exactly what counts as a bootstrapping case. Going back to Vogel's original bootstrapping example, I note that an agent who could gain justification through the method Vogel describes would have available a “no-lose investigation”: an investigation that can justify a proposition but has no possibility of undermining it. (...) The main suggestion of this article is that an epistemological theory should not permit no-lose investigations. I identify necessary and sufficient conditions for such investigations, then explore epistemological theories that rule them out. If we want to avoid both skepticism and no-lose investigations, we must eschew either Closure or epistemic externalism. (shrink)

What does it mean to say that mind-body dualism is causally problematic in a way that other mind-body theories, such as the psychophysical type identity theory, are not? After considering and rejecting various proposals, I advance my own, which focuses on what grounds the causal closure of the physical realm. A metametaphysical implication of my proposal is that philosophers working without the notion of grounding in their toolkit are metaphysically impoverished. They cannot do justice to the thought, encountered in every (...) introductory class in the philosophy of mind, that dualism has a special problem accounting for mental causation. (shrink)

The physical realm is causally closed, according to physicalists like me. But why is it causally closed, what metaphysically explains causal closure? I argue that reductive physicalists are committed to one explanation of causal closure to the exclusion of any independent explanation, and that as a result, they must give up on using a causal argument to attack mind–body dualism. Reductive physicalists should view dualism in much the way that we view the hypothesis that unicorns exist, or that the Kansas (...) City Royals won the 2003 World Series: false, but not objectionable in any distinctively causal way. My argument turns on connections between explanation, counterfactuals, and inductive confirmation.

Supposons un sceptique qui doute qu’il ait deux mains. Je montre tout d’abord que si on le compare au fou, cela coupe court à toute tentative de le comprendre. La raison en est non pas qu’il ne partage pas les mêmes croyances-charnières que nous, mais qu’il n’effectue aucun partage entre des croyances-charnières et des croyances susceptibles d’être révisées. Puis je propose un autre modèle à partir duquel le discours d’un sceptique peut apparaître comme intelligible : le modèle de la compréhension (...) interculturelle. Dans ce cadre, un sceptique n’est intelligible que s’il adhère à un système partagé de distribution entre des croyances-charnières et des croyances révisables, quand bien même il n’a pas les mêmes croyances-charnières que nous.

The aim of this paper is to analyse and develop how scepticism becomes an intelligible question starting from requirements that epistemologists themselves aim to endorse. We argue for and defend the idea that the root of scepticism is the underdetermination principle by articulating its specificitya respectable epistemic principle and by defending it against objections in current literature. This engagement offers a novel understanding of underdetermination-based scepticism. While most anti-sceptical approaches challenge scepticism by understanding it as postulating uneliminated scenarios of mass (...) deception, or as endorsing unnatural epistemic requirements, we argue here that both contentions are mistaken. Underdetermination-based scepticism targets our beliefs by issuing a genuine question about the rational support they enjoy. If we cannot establish that the sources of our beliefs provide them the required epistemic merit and authority, they lack non-arbitrary grounds. This has a sizable impact on what constitutes a satisfactory anti-sceptical strategy. Strategies that merely focus on the scenario-based aspect of scepticism, or on the truth-functional evaluation of our beliefs, are shown to miss the mark of the sceptical threat. The proposed analysis ultimately provides a shift in perspective concerning the character and reach of philosophical doubt. (shrink)

According to a view I’ll call Epistemic Normativism, knowledge is normative in the same sense in which paradigmatically normative properties like justification are normative. This paper argues against EN in two stages and defends a positive non-normativist alternative. After clarifying the target in §1, I consider in §2 some arguments for EN from the premise that knowledge entails justification. I first raise some worries about inferring constitution from entailment. I then rehearse the reasons why some epistemologists reject the Entailment Thesis (...) and argue that a non-normativist picture provides the best explanation of all the intuitions surrounding this thesis, favorable and unfavorable. On this picture, human knowledge is a structured non-normative complex that has as one of its parts a justification-making property, analogous in role to good-making properties like pleasurableness. After giving three arguments against EN in §3 and answering an objection in §4, I turn in §5 to further develop the positive view sketched in §2. In §6, I take stock and conclude. (shrink)

This paper is an opinionated guide to the literature on normative epistemic reasons. After making some distinctions in §1, I begin in §2 by discussing the ontology of normative epistemic reasons, assessing arguments for and against the view that they are mental states, and concluding that they are not mental states. In §3, I examine the distinction between normative epistemic reasons there are and normative epistemic reasons we possess. I offer a novel account of this distinction and argue that we (...) in fact ought to acknowledge a threefold distinction between objective, possessed, and apparent normative epistemic reasons. In §4, I discuss the question of which normative reasons for doxastic attitudes are the epistemic ones, evaluating reasons against a simple evidentialist answer. Finally, in §5, I look at the role of reasons in epistemology, considering challenges to viewing reasons as the building blocks of epistemic normativity and maintaining that the challenges recommend a novel bi-level epistemology rather than a marginalization of reasons in epistemology. (shrink)

The paper is an opinionated tour of the literature on the reasons for which we hold beliefs and other doxastic attitudes, which I call ‘operative epistemic reasons’. After drawing some distinctions in §1, I begin in §2 by discussing the ontology of operative epistemic reasons, assessing arguments for and against the view that they are mental states. I recommend a pluralist non-mentalist view that takes seriously the variety of operative epistemic reasons ascriptions and allows these reasons to be both propositions (...) and truth-making facts. In §3, I turn to consider what it takes for a consideration to be an operative epistemic reason, examining three conditions – the representational, treating, and explanatory conditions – that have been proposed. I offer a novel view about the explanatory condition. In §4, I discuss the special case of inferential operative reasons and examine attempts to understand them in terms of rule-following, sketching a competence-based spinoff of dispositionalism. Finally, in §5, I consider whether there are non-inferential operative reasons, observing that one needn't countenance them to be a foundationalist but then developing a view about what they are and how they do and don't differ from inferential reasons.

This paper considers the analogies and disanalogies between a certain sort of argument designed to oppose scepticism about free will and a certain sort of argument designed to oppose scepticism about the external world. In the case of free will, I offer the ancient Lazy Argument and an argument of my own, which I call the Agency Argument, as examples of the relevant genre; and in the case of the external world, I consider Moore’s alleged proof of an external world. (...) I draw attention to analogies and disanalogies between the arguments offered in each case in order to suggest that although the Agency Argument shares with its Moorean relative the unfortunate property of being dialectically ineffective against some of those it is mainly hoping to convince, it will not be dialectically ineffective against all of them. It is also argued that the Agency Argument is less vulnerable than Moore’s proof to worries about its justificatory structure. (shrink)

According to externalist reliabilism and dogmatic foundationalism, it's possible to gain knowledge through a perceptual experience without being in a position to know that the experience is reliable. As a result, both of these views face the problem of making knowledge of perceptual reliability too easy, for they permit deducing perceptual reliability from particular perceptual experience without already knowing that these experiences are trustworthy. Ernest Sosa advocates a two-stage solution to the problem. At the first stage, a rich body of (...) perceptual animal knowledge is acquired. At the second stage, perceptual knowledge becomes reflective after deducing perceptual reliability from the initial body of perceptual animal knowledge. I defend the alternative approach of rejecting both externalist reliabilism and dogmatic foundationalism. According to the alternative view, perceptual knowledge and knowledge of perceptual reliability require each other. Such a cognitive structure seems viciously circular. I propose that the appearance of vicious circularity dissipates when the relationship in question is viewed, not as one of temporal priority, but instead as synchronic mutual dependence. At a given time, one cannot have perceptual knowledge without knowledge of perceptual reliability, and vice versa. Such mutual dependence, I argue, is benign. (shrink)

Could there be a cognitive zombie – that is, a creature with the capacity for cognition, but no capacity for consciousness? Searle argues that there cannot be a cognitive zombie because there cannot be an intentional zombie: on this view, there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and intentionality. However, I argue that there are good empirical reasons for rejecting the proposed connection between consciousness and intentionality. Instead, I argue (...) that there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and rationality. On this view, there cannot be a cognitive zombie because there cannot be a rational zombie. (shrink)

In this paper I draw attention to a peculiar epistemic feature exhibited by certain deductively valid inferences. Certain deductively valid inferences are unable to enhance the reliability of one's belief that the conclusion is true—in a sense that will be fully explained. As I shall show, this feature is demonstrably present in certain philosophically significant inferences—such as GE Moore's notorious 'proof' of the existence of the external world. I suggest that this peculiar epistemic feature might be correlated with the much (...) discussed phenomenon that Crispin Wright and Martin Davies have called 'transmission failure'—the apparent failure, on the part of some deductively valid inferences to transmit one's justification for believing the premises. (shrink)

In this paper I defend the claim that justification is closed under conjunction, and confront its most alarming consequence — that one can have justification for believing propositions that are unlikely to be true, given one's evidence.

Entitlement is conceived as a kind of positive epistemic status, attaching to certain propositions, that involves no cognitive or intellectual accomplishment on the part of the beneficiary — a status that is in place by default. In this paper I will argue that the notion of entitlement — or something very like it — falls out of an idea that may at first blush seem rather disparate: that the evidential support relation can be understood as a kind of variably strict (...) conditional (in the sense of Lewis 1973). Lewis provided a general recipe for deriving what he termed inner modalities from any variably strict conditional governed by a logic meeting certain constraints. On my proposal, entitlement need be nothing more exotic than the inner necessity associated with evidential support. Understanding entitlement in this way helps to answer some common concerns — in particular, the concern that entitlement could only be a pragmatic, and not genuinely epistemic, status. (shrink)

When a belief has been influenced, in part or whole, by factors that, by the believer's own lights, do not bear on the truth of the believed proposition, we can say that the belief has been, in a sense, arbitrarily formed. Can such beliefs ever be rational? It might seem obvious that they can't. After all, belief, supposedly, “aims at the truth.” But many epistemologists have come to think that certain kinds of arbitrary beliefs can, indeed, be rational. In this (...) paper, I want to do two things. First, I want to show that the claim that arbitrary beliefs can be rational is inconsistent with the conjunction of two other attractive claims: one saying that rationality requires a certain kind of epistemic immodesty, and one saying that rationality forbids certain kinds of self-ascriptions of epistemic luck. Second, I want to evaluate different ways one might respond to this inconsistent triad. I won't defend any response in particular, but I'll draw out some notable costs and benefits of each response, which may help shed light on the question of whether arbitrary beliefs can be rational. (shrink)

In this paper, I’ll survey a number of closure principles of epistemic justification and find them all wanting. However, it’ll be my contention that there’s a novel closure principle of epistemic justification that has the virtues of its close cousin closure principles, without their vices. This closure principle of epistemic justification can be happily thought of as a multi-premise closure principle and it cannot be used in Cartesian skeptical arguments that employ a closure principle of epistemic justification. In this way, (...) then, it represents marked improvement over other contemporary closure principles of epistemic justification that require both sacrificing multi-premise closure and forcing anti-Cartesian skeptics who reject the closure principle employed in certain Cartesian skeptical arguments to cast aside justification closure.

Recent views in hinge epistemology rely on doxastic normativism to argue that our attitudes towards hinge propositions are not beliefs. This paper has two aims; the first is positive: it discusses the general normative credentials of this move. The second is negative: it delivers two negative results for No-Belief hinge epistemology such construed. The first concerns the motivation for the view: if we’re right, doxastic normativism offers little in the way of theoretical support for the claim that our attitudes towards (...) hinge propositions are anything but garden-variety beliefs. The second concerns theoretical fruitfulness: we show that embracing a No-Belief view will either get us in serious theoretical trouble, or loose all anti-sceptical appeal. (shrink)

I set out the standard view about alleged examples of failure of transmission of warrant, respond to two cases for the view, and argue that the view is false. The first argument for the view neglects the distinction between believing a proposition on the basis of a justification and merely having a justification to believe a proposition. The second argument for the view neglects the position that one's justification for believing a conclusion can be one's premise for the conclusion, rather (...) than simply one's justification for the premise. Finally, the view is false since it is inconsistent with the closure of knowledge as closure is properly understood. (shrink)

According to many, to have epistemic justification to believe P is just for it to be epistemically permissible to believe P. Others think it is for believing P to be epistemically good. Yet others think it has to do with being epistemically blameless in believing P. All such views of justification encounter problems. Here, a new view of justification is proposed according to which justification is a kind of composite normative status. The result is a view of justification that offers (...) hope of solving some longstanding epistemological problems. (shrink)

I provide a novel knowledge-first account of justification that avoids the pitfalls of existing accounts while preserving the underlying insight of knowledge-first epistemologies: that knowledge comes first. The view I propose is, roughly, this: justification is grounded in our practical knowledge (know-how) concerning the acquisition of propositional knowledge (knowledge-that). I first refine my thesis in response to immediate objections. In subsequent sections I explain the various ways in which this thesis is theoretically superior to existing knowledge-first accounts of justification. The (...) upshot is a virtue-theoretic, knowledge-first view of justification that is internalist-friendly and able to explain more facts about justification than any other available view. (shrink)

This is a critical piece on *The Character of Consciousness* by David Chalmers. It focuses on Chalmers's two-stage view of perceptual content and the epistemology of perceptual belief that flows from this theory, and criticizes his theories of Edenic concepts, perceptual acquaintance, and perceptual belief.

ABSTRACT This article aims to achieve two things: to identify the conditions for transitivity in probabilistic support in various settings, and to uncover the components and structure of the mediated probabilistic relation. It is shown that when the probabilistic relation between the two propositions, x and z, is mediated by multiple layers of partitions of propositions, the impact x has on z consists of the purely indirect impact, the purely bypass impact, and the mixed impact. It is also shown that (...) although mediated confirmation as a whole is not transitive, the indirect part of mediated confirmation is transitive. _1_ Introduction _2_ The Structure of the Mediated Probabilistic Relation _3_ Transitivity and Anti-transitivity _4_ Bypass Disconfirmation _5_ Horizontal Generalization _6_ Coarse Screens _7_ Vertical Generalization _8_ Conclusion Appendix.

In this paper I develop an account of petitio principii (the fallacy sometimes also called ‘vicious circularity’, or ‘begging the question’) which has two crucial features: it employs the notion of doxastic justification, and it takes circularity to be relative to an evidential state. According to my account, an argument will be circular relative to an evidential state if and only if having doxastic justification for the conclusion is necessary, for a subject in that evidential state, to have doxastic justification (...) for the premisses. I compare the account to some existing ones, and claim some advantages. I then rebut an objection which threatens to undermine the importance of one of those advantages. This account seems to shed new light on the old problem of characterizing petitio principii. It avoids the two obvious problems which any account of this phenomenon must face: being too narrow, for example by leaving out all arguments in which the conclusion does not appear among the premisses, and being too wide, making all valid arguments circular.
