Sünnî usulcülere göre sahih olan haber-i vahid zan ifade etmekle birlikte, böyle bir haberle amel etmek naklî ve kat’î delillerin bir gereği olarak vaciptir. Şiî-Usûlî geleneğin temsilcilerinden Şerif Murtazâ ise haber-i vâhidle amel etmenin aklen caiz olduğunu, ancak bunun dinî açıdan vacip olmadığını iddia etmiştir. Ona göre Kur’an, mütevâtir haber ve masum imamın dâhil olduğu icmâ kesin bilgi kaynağı olduğundan bağlayıcıdır. Haber-i vâhid ise zann ifade etmektedir. Böyle bir haberle amel etmeyi gerektiren naklî kat’î bir delil (...) ise bulunmamaktadır. Bu nedenle haber-i vâhid amelî konularda hüccet değildir. Şerif Murtazâ, Sünnî usulcülerin haber-i vâhidin hüccet olduğuna dair naklî kat’î delillerini eleştirmiş, usulcüler ise bu eleştirilere cevap vermişlerdir. Araştırmamız Şiî-Usûlî geleneğin haber-i vâhide yaklaşım evreninden Şerif Murtazâ örneğini ele almayı ve Sünnî usulcülerin görüşleriyle mukayese etmek suretiyle değerlendirmeyi hedeflemektedir. Şerif Murtazâ’nın âhâd haber konusundaki yaklaşımı özü itibarıyla masum imam teolojisine dayanmakta-dır. Araştırmada masum imam teolojisinin ve haber-i vâhidle amel etmeyi gerektiren kat’î bir delilin bulunmadığı iddiasının nas, icmâ, tevâtür ve makul açısından vakıaya aykırı tutarsız bir görüş olduğu tespit edilmiştir.

Fıkıh literatüründe sünnet önemli bir yere sahiptir. Çünkü fıkhın temeli Hz. Peygamber tarafından atılmış ve fıkhın gayesini en iyi bilen ve uygulayan kendisi olmuştur. Bu sebeple şer’î amelî konularda hüküm istinbatı için müctehid imamlar, Kur’an’dan sonra sünnete başvurmuşlardır. Bununla birlikte müctehid imamlar, Hz. Peygamber’den gelen rivayetlerin bazılarını kabul ve onlarla amel etmede görüş ayrılıkları yaşamışlardır. Görüş ayrılıklarının temelinde ise sünnetin ekseriyetini teşkil eden haber-i vâhid vardır. Çünkü haber-i vâhid yapısal açıdan yalan, yanlışlık ve vehm ihtimali bulundurması yanında doğruluğu (...) zan ile sabit olması sebebiyle özellikle Hanefî usûlcülerine göre bilgi ifade etmez. Bu yönüyle haberi vâhid, mütevâtir haber kadar kuvvetli ve bağlayıcı olmayıp zannî bir bilgi ifade eder. Bu doğrultuda haber-i vâhid, “bilgi gerektirmez, zan gerektirir” şeklinde ifade edilmiştir. Bu ifade bağlamında şöyle bir soru ortaya çıkmaktadır: Haber-i vâhid, bilgi ifade etmediği halde, onunla amel edilmesi mümkün müdür? Bu sorudan hareketle zan ifade eden haber-i vâhidin hücceti ve onunla amel edilmesinin mümkün olup olmadığını, mezheplerin haber-i vâhide yaklaşımlarının nasıl olduğunu ve bu durumun cenaze bahsine ilişkin hükümlere nasıl yansıdığını ortaya koymak amacıyla bu çalışma ele alınmıştır. Dolayısıyla bu çalışmanın konusu, haber-i vâhidin hücceti için mezheplerin ileri sürdüğü farklı şartlar ve bu şartların hükümlere -cenaze namazı özelinde- etkisi ile sınırlıdır. Yöntem olarak öncelikle kavramsal çerçevede haber-i vâhidi tanımlamak, bilgi değerini ortaya koymak ve mezheplerin onunla hücceti noktasında benimsedikleri şartları tespit etmek amacıyla ilgili mezheplerin usûl eserleri incelenmiştir. Daha sonra mezheplerin benimsediği bu usûlî yöntem, cenaze bahsindeki yerini belirlemek üzere ilgili mezheplerin fürû kitapları taranmıştır. Bu metottan hareketle mezheplerin usûlde benimsediği ilkenin fürû meselelerine nasıl yansıdığı, haber-î vâhidin zannî bilgi ifade etmesine rağmen onunla amel etmenin gerekçesi ve cenazeye ilişkin bazı hükümlerde mezheplerin farklı hüküm benimsemelerinin nedeni ortaya konulacaktır.

Ensuring the trustworthiness of autonomous systems and artificial intelligence is an important interdisciplinary endeavour. In this position paper, we argue that this endeavour will benefit from technical advancements in capturing various forms of responsibility, and we present a comprehensive research agenda to achieve this. In particular, we argue that ensuring the reliability of autonomous system can take advantage of technical approaches for quantifying degrees of responsibility and for coordinating tasks based on that. Moreover, we deem that, in certifying the legality (...) of an AI system, formal and computationally implementable notions of _responsibility_, _blame_, _accountability_, and _liability_ are applicable for addressing potential responsibility gaps (i.e. situations in which a group is responsible, but individuals’ responsibility may be unclear). This is a call to enable AI systems themselves, as well as those involved in the design, monitoring, and governance of AI systems, to represent and reason about who can be seen as responsible in prospect (e.g. for completing a task in future) and who can be seen as responsible retrospectively (e.g. for a failure that has already occurred). To that end, in this work, we show that across all stages of the design, development, and deployment of trustworthy autonomous systems (TAS), responsibility reasoning should play a key role. This position paper is the first step towards establishing a road map and research agenda on how the notion of responsibility can provide novel solution concepts for ensuring the _reliability_ and _legality_ of TAS and, as a result, enables an effective embedding of AI technologies into society.

While recent debates over content externalism have been mainly concerned with whether it undermines the traditional thesis of privileged self‐knowledge, little attention has been paid to what bearing content externalism has on such important controversies as the internalism/externalism debate in epistemology.

To undermine much of what we ordinarily claim to know, sceptics have often appealed to a principle (known as the principle of closure) according to which knowledge (justification) is closed under known entailment. In this paper after expounding the views of Stein, Klein and others, I shall argue that they all fail to take note of different contexts in which the principle of closure is applied. The relevance of the principle of closure for scepticism is then analyzed in the light (...) of, what I call, the infectious' character of epistemic contexts. I shall also highlight the similarities in the behavior of the concepts of justification and confirmation and appeal to certain solutions to the paradoxes of confirmation to provide a comprehensive account of the different instances of the principle of closure.

The relation between method, concept and theory in science is complicated. I seek to shed light on that relation by considering an instance of it in systematics: The additional challenges phylogeneticists face when reconstructing phylogeny not at a single level, but simultaneously at multiple levels of the hierarchy. How does this complicate the task of phylogenetic inference, and how might it inform and shape the conceptual foundations of phylogenetics? This offers a lens through which the interplay of method, theory and (...) concepts may be understood in systematics, which, in turn, provides data for a more general account. (shrink)

Despite the increasing sophistication of the arguments used by the proponents of the internalist and externalist accounts of justification, the dispute shows no sign of abating. This paper aims at providing an explanation for the current stalemate by showing how the controversy relates to an older debate between the idealists and realists. The two disputes, it will be argued, are fuelled by the same concerns and motivations to an extent that the internalism/externalism controversy may be regarded as the epistemization of (...) the latter debate. The question is no longer whether to be is to be perceived, but whether to be a justifying ground is to be perceived. After noting how different strengths of idealism find their analogue in internalism, I shall further reinforce the claims just made by showing how the problems usually associated with the opposite sides of idealism/realism dispute find an echo in the internalism/externalism controversy.

Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the notion of fallible knowledge, (...) I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.

The basing relation is a relation that obtains between a belief and the evidence or reason for which it is held. It is a highly controversial question in epistemology how such a relation should be characterized. Almost all epistemologists believe that causation must play a role in articulating the notion of the basing relation. The causal account however faces the serious problem of the deviant causal chains. In this paper, I will be particularly looking at the philosophers’ appeal to the (...) notion of disposition as a way of excluding deviant chains. Having argued against such accounts, it will be suggested that, since the obtaining of the basing relation is what distinguishes propositional from doxastic justification, we may have a better grasp of this notion if we could clearly see how those two species of justification are related to one another. Drawing on earlier work, a dispositional account of propositional and doxastic justification is subsequently defended. It will be argued that such a view has the resources to resolve the problem of causal deviance, thus, providing an acceptable account of the notion of the basing relation. (shrink)

Although touch frequently occurs in psychotherapy with children, there is little written on the ethical considerations of therapeutic touch. Because physical contact does occur, therapists must consider if, how, and when it is used, for both their clients' safety and their own. In this review, I further develop the issues suggested by Aquino and Lee (2000) in the use of nurturing touch in therapy by considering many types of touch that occur in psychotherapy with children; the possible positive role of (...) touch; clients' perception of touch in therapy; considerations related to the therapist, the child's safety, and any history of abuse in the child's and family's background; and other practical considerations. I list guidelines. (shrink)

The repair of chromosomal double‐strand breaks (DSBs) by homologous recombination is essential to maintain genome integrity. The key step in DSB repair is the RecA/Rad51‐mediated process to match sequences at the broken end to homologous donor sequences that can be used as a template to repair the lesion. Here, in reviewing research about DSB repair, I consider the many factors that appear to play important roles in the successful search for homology by several homologous recombination mechanisms.

According to the thesis of epistemic conservatism it would be unreasonable to change one's beliefs in the absence of any good reasons. Although it is claimed that epistemic conservatism has informed and resolved a number of positions and problems in epistemology, it is difficult to identify a single representative view of the thesis. This has resulted in advancing a series of disparate and largely unconnected arguments to establish conservatism. In this paper, I begin by casting doubt on the claim of (...) widespread and genuine applications of the conservative policy. I then distinguish between three main varieties of epistemic conservatism, namely, differential, perseverance and generation conservatism Having evaluated various arguments that have been offered or may be considered on behalf of the conservative thesis, I close by concluding that those versions of the thesis that survive critical scrutiny fail to live up to the aspirations of the thesis as a substantive canon of rationality, that to the extent that principles of conservatism are epistemically promising, they are not plausible. While to the extent that they are plausible, they are not of much epistemic interest. (shrink)

Belief is generally thought to be the primary cognitive state representing the world as being a certain way, regulating our behavior and guiding us around the world. It is thus regarded as being constitutively linked with the truth of its content. This feature of belief has been famously captured in the thesis that believing is a purposive state aiming at truth. It has however proved to be notoriously difficult to explain what the thesis really involves. In this paper, I begin (...) by critically examining a number of recent attempts to unpack the metaphor. I shall then proceed to highlight an error that seems to cripple most of these attempts. This involves the confusion between, what I call, doxastic and epistemic goals. Finally, having offered my own positive account of the aim-of-belief thesis, I shall underline its deflationary nature by distinguishing between aiming at truth and hitting that target (truth). I end by comparing the account with certain prominent inflationary theories of the nature of belief. (shrink)

Any theory of epistemic justification must address the question of what its aim is and why we value it. The almost general consensus among epistemologists is that there is an intimate link between justification and truth. However, the standard formu- lation of this connection (as the truth-directed goal of maximizing true belief and minimizing false belief) has been increasingly challenged in recent times on the ground that it leaves no room for justified false beliefs and unjustified true beliefs. In this (...) paper, I shall argue for a diachronic version of the truth-directed goal in the face of the objections raised against it. To provide further support for this conclusion, I criticize Foley’s synchronic account of the truth-directed goal by showing how it is undermined by certain consequences of his egocentric theory of epistemic rationality. (shrink)

An important question in epistemology concerns how the two species of justification, propositional and doxastic justification, are related to one another. According to the received view, basing one’s belief p on the grounds that provide propositional justification to believe p is sufficient for the belief to be doxastically justified. In a recent paper, however, John Turri has suggested that we should reverse the direction of explanation. In this paper, I propose to see the debate in a new light by suggesting (...) that the best way to understand the relationship between these species of justification is by viewing propositional justification as an dispositional property that a subject can have with doxastic justification as its manifestation. I show how the debate in metaphysics over the question of how disposition statements should be analyzed runs parallel to the epistemological debate, and bring some of the results in the dispositions debate to bear on the epistemological question. I end by offering some tentative remarks regarding the order of priority of these two species of justification. (shrink)

Despite the important role of faith in a religious way of life, there is no consensus on how this notion is to be understood. It is nevertheless widely believed that faith is a multifaceted concept possessing affective, evaluative, practical, and cognitive aspects. My goal in this paper is to provide an account of the nature of propositional faith (in religious contexts) that is flexible enough to encompass different strengths or grades of faith. To do so, I focus on Howard-Snyder’s account (...) of faith as a complex propositional attitude that seems to incorporate a number of plausible features of faith. It is argued, however, that, despite providing individual rational for each such feature, this account fails to provide a deep enough explanation of why those features are entailed by the nature of faith. To rectify this problem, I appeal to the phenomenology of acquiring faith to suggest an account of propositional faith in terms of the intention to form (theistic) beliefs. It is claimed that such a view can not only provide a unitary account of the different strengths of faith but also that it can explain why faith has the characteristics it is said to have. (shrink)

Distance Interpreting (DI) is a form of technology-mediated interpreting which has gained traction due to the high demand for multilingual conferences, live-streaming programs, and public service sectors. The current study synthesized the DI literature to build a framework that represents the construct and measurement of cognitive load in DI. Two major areas of research were identified, i.e., causal factors and methods of measuring cognitive load. A number of causal factors that can induce change in cognitive load in DI were identified (...) and reviewed. These included factors derived from tasks (e.g., mode of presentation), environment (e.g., booth type), and interpreters (e.g., technology awareness). In addition, four methods for measuring cognitive load in DI were identified and surveyed: subjective methods, performance methods, analytical methods, and psycho-physiological methods. Together, the causal factors and measurement methods provide a multifarious approach to delineating and quantifying cognitive load in DI. This multidimensional framework can be applied as a tool for pedagogical design in interpreting programs at both the undergraduate and graduate levels. It can also provide implications for other fields of educational psychology and language learning and assessment. (shrink)

It has been argued that just as, say, prejudice or wishful thinking can generate ill-founded beliefs, the same is true of experiences. The idea is that the etiology of cognitively penetrated experiences can downgrade their justificatory force. This view, known as the Downgrade Principle, seems to be compatible with both internalist and externalist conceptions of epistemic justification. An assessment of the credentials of the Downgrade Principle is particularly important in view of the fact that not all cases of cognitive penetration (...) are epistemically malignant. There are good and bad cases of cognitive penetration. I argue that a proper assessment of the Downgrade Principle will have to address two fundamental questions. I identify two general ways of responding to these questions and show why they fail. It will be maintained that an explanationist conception of justification has a better chance of accounting for the distinction between good and bad cases of cognitive penetration. The Downgrade Principle is then discussed in the context of the extended cognition thesis. In particular, I look at the sensorimotor theory of perception, as a way of broadening the scope of to include conscious perceptual experience, that sees senses as ways of exploring the environment mediated by different patterns of sensorimotor contingency. I suggest possible ways in which one could distinguish between good and bad cases of cognitive penetration on such a view compatible with the explanationist view of epistemic justification. (shrink)

Epistemic reasons are meant to provide justification for beliefs. In this paper, I will be concerned with the requirements that have to be met if reasons are to discharge this function. It is widely recognized, however, that only possessed reasons can justify beliefs and actions. But what are the conditions that have to be satisfied in order for one to possess reasons? I shall begin by motivating a particular condition, namely, the ‘treating’ requirement that has been deemed to be necessary (...) for possessing reasons. In Sect. 1, I explain and criticize some of the existing accounts of the treating requirement for reason-possession. In Sect. 2, I will suggest a dispositional account of reason-possession in which the treating condition features prominently. Section 3 will deal with the some of the consequences of this account for such issues as the structure of epistemic defeat, the immediacy of perceptual justification and logical knowledge. (shrink)

Beliefs can be evaluated from a number of perspectives. Epistemic evaluation involves epistemic standards and appropriate epistemic goals. On a truthconducive account of epistemic justification, a justified belief is one that serves the goal of believing truths and avoiding falsehoods. Beliefs are also prompted by nonepistemic reasons. This raises the question of whether, say, the pragmatic benefits of a belief are able to rationalize it. In this paper, after criticizing certain responses to this question, I shall argue that, as far (...) as beliefs are concerned, justification has an essentially epistemic character. This conclusion is then qualified by considering the conditions under which pragmatic consequences of a belief can be epistemically relevant. (shrink)

Theories of epistemic justification are usually described as belonging to either deontological or nondeontological categories of justification with the former construing the concept of justification as involving the fulfillment of epistemic duty. Despite being the dominant view among traditional epistemologists, the deontological conception has been subjected to severe criticisms in the current literature for failing, among others, to do justice to the (alleged) truth-conducive character of epistemic justification. In this paper I set out to show that there is something deeply (...) unsatisfying about the way these different conceptions of justification are usually introduced and contrasted with each other leaving it unclear just what it is that renders a particular conception deontological. In particular I look at Alston's treatment of the issue, and show that his reasons for rejecting the deontological conception involve question-begging assumptions demonstrating, at best, the possibility of its divergence from truth-conductive justification. Far from being able to settle the issue one way or another, the arguments, I shall suggest actually seem to show some sort of tolerant pluralism in justification theory to be a live option. (shrink)

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

It has been claimed that friendship not only involves partial treatment of one's friends but that it also involves some degree of doxastic partiality towards them. Taking these claims as their starting points, some philosophers have argued that friendship not only involves such partiality but that this is also what is normatively required. This gives rise to the possibility of conflict between the demands of friendship on the one hand and the demands of epistemic norms on the other. In this (...) paper, I consider some of the responses to this claim and show why they fail. I distinguish between different grades of doxastic partiality and explain why, although low grades of doxastic partiality fall within the bounds of the standard epistemic norm, the higher grades might infringe such norms. I conclude with an explanation of a fundamental intuition that seems to lie at the heart of the thesis of epistemic partiality. (shrink)

One of the well-known theses of Alvin Plantinga’s epistemology of religious belief is his claim about the noetic effects of sin. But Plantinga does not clearly spell out how sin functions to undermine or weaken the believer’s natural knowledge of God. In this paper, I want to suggest a dispositional gloss on his account of religious epistemology that properly identifies the epistemic role of sin and other factors that may undermine knowledge of God. It will be further argued that the (...) dispositional framework provides us with a principled basis for deriving some of the main contours of Plantinga’s general epistemology. (shrink)

I spell out and update the individuality thesis, that species are individuals, and not classes, sets, or kinds. I offer three complementary presentations of this thesis. First, as a way of resolving an inconsistent triad about natural kinds; second, as a phylogenetic systematics theoretical perspective; and, finally, as a novel recursive account of an evolved character. These approaches do different sorts of work, serving different interests. Presenting them together produces a taxonomy of the debates over the thesis, and isolates ways (...) it has been productive. This goes to the larger point of this paper: a defense of the individuality thesis in terms of its utility, and an update of it in light of recent theoretical developments and empirical work in biology.

_ Source: _Page Count 19 Epistemic akrasia refers to the possibility of forming an attitude that fails to conform to one’s best judgment.

Addressing this question, in turn, raises the question of the epistemic significance of higher-order evidence. After examining some of the views on this subject, I will present an argument to show why higher-order evidence is (...) relevant to the epistemic status of the pertinent first-order beliefs. This helps to show why a standard argument for the rationality of epistemic akrasia does not work. Finally, I shall try to show how considerations involving Davidson’s theory of radical interpretation bear on the question of the rationality of epistemic akrasia. (shrink)

Abstract: Moore's sentences of the form "P & ∼I believe that P" and "P & I believe that ∼P" are thought to be paradoxical because they cannot be properly asserted despite being possibly true. Solutions to the paradox usually explain the oddity of such sentences in terms of phenomena as diverse as the pragmatics of speech acts, nature of belief or justification. In this paper I shall argue that despite their seemingly different approaches to the problem, there is a single (...) strategy that underlies all such proposals. Having criticized these suggestions, I shall defend my own solution according to which Moorean sentences are defective not because of some associated logical impropriety but because their assertion violates a certain interpretive constraint, viz., the principle of charity, on an adequate theory of meaning.

Recent discussions of externalism about mental content have been dominated by the question whether it undermines the intuitively plausible idea that we have knowledge of the contents of our thoughts. In this article I focus on one main line of reasoning (the so-called 'slow switching argument') for the thesis that externalism and self-knowledge are incompatible. After criticizing a number of influential responses to the argument, I set out to explain why it fails. It will be claimed that the argument trades (...) on an ambiguity, and that only by incorporating certain controversial assumptions does it stand a chance of establishing its conclusion. Finally, drawing on an analogy with Benacerraf's challenge to Platonism, I shall offer some reasons as to why the slow switching argument fails to reveal the real source of tension between externalism and privileged self-knowledge.

Crispin Wright has recently suggested that, in addition to the notion of justification, we also possess a non-evidential notion of warrant, ‘entitlement’, that can play an important role in responding to various skeptical questions. My concern here is with the question of whether entitlement constitutes an epistemic kind of warrant. I claim Wright's argument for this thesis at most shows that entitlement has a pragmatic character. Having identified the sources of the troubles of this argument in its underlying assumptions, I (...) examine and criticize a number of attempts that have sought to substantiate those assumptions. I offer some suggestions as to how one can improve on Wright's account and make some general observations about the prospects of showing that entitlement is an epistemic type of warrant. (shrink)

Emotions play vital roles in our psychology and our lives. They also often form the basis of our evaluative beliefs. On some views, emotions, like perceptions, justify the beliefs to which they give rise. It has, however, been claimed that, unlike perceptions, emotions are merely proxies for the genuine reasons that are constituted by their cognitive bases. In this paper, I argue that this objection arises from the failure to notice the difference between the notions of ‘reasons there are’ and (...) ‘possessed reasons’. After developing an account of what it is to possess a reason, it will be argued that emotions do constitute genuine reasons for the evaluative beliefs that result from them. To support this claim, a distinction is made between thinner and thicker descriptions of the same event, where a thinner description may be in terms of the emotional response, whereas a thicker description may be in terms of possessing a normative reason to hold a belief or to act.

Biological lineages move through time, space, and each other. As they do, they diversify, diverge, and grade away from and into one another. One result of this is genealogical discordance; i.e., the lineages of a biological entity may have different histories. We see this on numerous levels, from microbial networks, to holobionts, to population-level lineages. This paper considers how genealogical discordance impacts our study of species. More specifically, I consider this in the context of three framing questions: (1) How, if (...) at all, does genealogical discordance challenge, modify, or revise how we conceive of species? (2) How has growing appreciation of genealogical discordance impacted scientific practice? Of systematics in particular? (3) How do lineages at different levels diverge and diversify? All told, genealogical discordance enriches and complicates our taxonomic ontology, as well as the practice of reconstructing phylogenies. This presents both challenges and opportunities for the study of divergence and diversification. (shrink)

Theoretical reasoning (inference) is a conscious personal‐level activity and a causal process. It is the process of revising one's beliefs for a reason whereby some of our beliefs cause or result in other beliefs. But inference is more than mere causation. This raises the question of what exactly distinguishes theoretical reasoning from mere causal processes. Paul Boghossian has located the distinguishing feature of inference in, what he calls, the “taking condition” requirement (TC). It turns out, however, that all attempts to (...) explain this notion fail. In this paper, I shall offer an indirect argument for the taking condition grounded in a specific account of the structure of epistemic reasons that distinguishes two levels of epistemic normativity, namely, the possession and justification levels. I show how such an account can legitimize the role of (TC) in reasoning and deflect the standard objections raised against it. Finally, I explain how this proposal naturally accommodates the defeasibility of reasoning. (shrink)

In this paper, I shall examine William Alston's influential view that the cognitive element in religious faith should be identified with ‘acceptance’ rather than ‘belief’. Although I am sympathetic to Alston's reluctance to regard belief as essential to faith, I shall argue that one can redescribe the cases that Alston invokes in support of his claim in terms of the standard notion of degrees‐of‐belief without loss. It will be further argued that, given Alston's constraints, his notion of acceptance, if not (...) identical to belief, is at least a species of belief. (shrink)

Type specimens are used to designate species. What is the nature of the relation between a type specimen and the species it designates? If species names are rigid designators, and type specimens ostensively define species, then that relation is, at the very least, a close one. Levine :325–338, 2001) argues that the relationship of type specimen to a named species is one of necessity—and that this presents problems for the individuality thesis. Namely, it seems odd that a contingently selected specimen (...) should belong to a species of necessity. In considering Levine’s argument, LaPorte suggests that recognizing the distinction between de re and de dicto necessity resolves Levine’s worries. I reconsider the motivating question: does a type specimen belong of necessity to the species that it designates? In light of taxonomic cases and practice the answer is clear: definitively not. This is particularly clear in the case of re-designation of types by taxonomic decree. I explain how this helps reveal how taxonomists prioritize competing theoretical commitments, and offer a defense of the individuality thesis as applied to these particular cases. In short, I demonstrate how to misidentify a type specimen. (shrink)

Transcendental arguments have been described as disclosing the necessary conditions of the possibility of phenomena as diverse as experience, self-knowledge and language. Although many theorists saw them as powerful means to combat varieties of skepticism, this optimism gradually waned as many such arguments turned out, on examination, to deliver much less than was originally thought. In this paper, I distinguish between two species of transcendental arguments claiming that they do not actually constitute distinct forms of reasoning by showing how they (...) collapse into more familiar inferences. I then turn to the question of their epistemic potentials which I argue to be a function of both their types as well as their targets. Finally, these claims are reinforced by uncovering links between certain recent claims about the efficacy of transcendental arguments and the so-called Moore’s paradox. (shrink)

Beliefs are most naturally formed in response to truth-related, epistemic reasons. But they are also said to be prompted and justified by non-epistemic reasons. For pragmatists who maintain such a view, sometimes the potential benefits of a belief might demand believing it even though it is not adequately grounded. For evidentialists, only evidential considerations constitute normative reasons for doxastic attitudes. This paper critically examines two arguments by Thomas Kelly and Nishi Shah from delibera­tion for evidentialism. I begin by putting these (...) arguments in perspective by providing a context to make sense of their normative force and explain their differences. To do so, I briefly explain what I call the “dispositional” structure of epistemic reasons. This is followed by some critical remarks about Jona­than Way’s improved version of such arguments. I conclude by explaining how the dispositional account can explain why practical considerations fail to provide reasons for belief. (shrink)

According to a recent view, known as the 'pragmatic encroachment' thesis, an agent’s non-truth-related factors are relevant to the epistemic status of her beliefs. In particular, in addition to truth-related factors, practical factors are said to be relevant to the question whether or not true belief amounts to knowledge. Despite the intuitive appeal of the thesis, however, it is puzzling how practical factors can impact the truth-related factors that ground the epistemic status of one's beliefs. In this paper, I will (...) distinguish between a strong and a weak sense of the way in which practical factors are said to be thus relevant. Their differences are explicated in terms of the nature and the extent to which practical factors are said to impact the epistemic status of one's beliefs. I begin by considering a strong version of the thesis that suggests principles according to which the practical rationality of one's actions is a necessary condition on knowledge and justification. Having noted an inadequacy in the formulation of such principles, the arguments in their support are subsequently stated and criticized. Finally, I identify two modest versions of the thesis of pragmatic encroachment and argue that they, too, fail to explain how practical factors can bear on the epistemic status of one's beliefs.

It is widely believed that what distinguishes between a justifiable and a justified belief is the obtaining of an epistemic relation, the basing relation, whose nature and character has long been a controversial issue in epistemology. There are currently two major approaches to the problem of the basing relation, namely, the causal and doxastic theories. In this paper, after a brief survey of the field, I examine Alston's recent account of the basing relation, as input to psychologically realized functions, arguing (...) that his way of identifying the functions in question presupposes what it seeks to establish as it merely replaces one kind of indeterminacy with another . To avoid this problem, I suggest a version of Alston's account within a broadly Davidsonian framework. (shrink)

Current responses to the question of how one should adjust one’s beliefs in response to peer disagreement have, in general, formed a spectrum at one end of which sit the so-called ‘conciliatory’ views and whose other end is occupied by the ‘steadfast’ views. While the conciliatory views of disagreement maintain that one is required to make doxastic conciliation when faced with an epistemic peer who holds a different stance on a particular subject, the steadfast views allow us to maintain our (...) confidence in our relevant beliefs. My aim in this paper is not to adjudicate between these views. Rather, I shall focus on a particular strategy, namely, denying the appearance of epistemic symmetry between peers, that the steadfast views standardly invoke in support of their position. Having closely examined certain representative examples of the steadfast approach, I will argue that this strategy is fundamentally flawed. (shrink)

According to one prominent account of perceptual justification, “dogmatism,” whenever you have perceptual experience as if p, and lack defeaters, you thereby have immediate, prima facie justification for believing that p. The most important challenge is to show how experience can, on its own, provide justification for the belief in its content. Dogmatists often try to meet this challenge by highlighting the phenomenal character of perceptual experience and the mode of presentation of its content and defending their justifying roles by (...) appealing to intuitively plausible examples. What is lacking here, however, is a theoretical framework to sanction and justify those roles going beyond the mere appeal to examples. Finding such a framework is the main goal of this article. I begin by criticizing a prominent response to this challenge, which suggests a composition view of perceptual experience consisting of sensory experiences and seemings. I then highlight the need for a theoretical framework to provide the rationale for the justifying roles that dogmatists allocate to perceptual experience. It is claimed that the framework in question involves the mechanism by which we possess reasons. Adapting the framework to cases where perception functions as a reason, a principled defense of dogmatism is provided. (shrink)

In a number of articles Donald Davidson has argued that the charitable nature of his method of radical interpretation rules out the possibility of massive error and thus refutes Cartesian skepticism. The diversity of such arguments and the suggestions that are all being made under the name of the principle of charity have prompted a large body of conflicting responses, adding only to the obscurity of the issues that are generally associated with the question of skepticism. In this paper I (...) propose to consider the debate in a new light by reconstruing the principle of charity as a supervenience constraint on belief attribution. This would help explain some of the puzzling features of Davidson's arguments, like the idea of an omniscient interpreter, and the ensuing commentaries. Having provided an analysis of the limitations of Davidson's arguments, I shall then suggest an alternative explanation of the purported necessity of the principle of charity. Finally, having construed the principle of charity as a supervenience constraint, I shall examine what consequences this construal has for the logical status of the principle itself and its alleged epistemic potentials.

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.

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.

While there is general agreement that knowing a proposition p involves knowing that nothing incompatible with p is true, there is much controversy over the range of possibilities that have to be ruled out if knowledge claims are to be sustained. With the failure of attempts on behalf of commonsense to delimit the range of counterpossibilities in order to leave room for knowledge, some theorists, most notably Adler, have sought to introduce a set of so-called ‘universalizability principles’ that require us (...) to extend our epistemic judgments about particular beliefs to those held under similar circumstances. These principles, it is claimed, not only identify which counterpossibilities must be countenanced, but also have enough power to generate skeptical results. In this paper I distinguish between minimalist and full-blooded versions of the universalizability thesis, and argue that the thesis can have skeptical consequences only when conjoined with certain epistemically significant assumptions. This is followed by a discussion of the epistemic import of the minimalist version of the thesis by considering how it can arise naturally in epistemic contexts, in virtue of either being semantically linked to the concept of justification or as a result of enforcing certain constraints on its application.

It is not difficult to make sense of the idea that beliefs may derive their justification from other beliefs. Difficulties surface when, as in certain epistemological theories, one appeals to sensory experiences to give an account of the structure of justification. This gives rise to the so-called problem of ‘nondoxastic justification’, namely, the problem of seeing how sensory experiences can confer justification on the beliefs they give rise to. In this paper, I begin by criticizing a number of theories that (...) are currently on offer. Finding them all wanting, I shall then offer a diagnosis of why they fail while gesturing towards a promising way of resolving the dispute. It will be argued that what makes the problem of nondoxastic justification a hard one is the difficulty of striking the right balance between a notion of normative justification that is content-sensitive and truth conducive and the possibility of error while acknowledging the fact that our experiences can justify our beliefs in cases we are hallucinating.
