Epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Evolution by natural selection is the most familiar source of etiological functions. . What then of learning? What then of Swampman? Though functions require history, natural selection is not the only source. Self-repair and trial-and-error learning are both sources. Warrant requires history, but not necessarily that much.

Let ‘warrant’ denote whatever precisely it is that makes the difference between knowledge and mere true belief. A current debate in epistemology asks whether warrant entails truth, i.e., whether (Infallibilism) S’s belief that p is warranted only if p is true. The arguments for infallibilism have come under considerable and, as of yet, unanswered objections. In this paper, I will defend infallibilism. In Part I, I advance a new argument for infallibilism; the basic outline is as follows. Suppose (...) fallibilism is true. An implication of fallibilism is that the property that makes the difference between knowledge and mere belief (which I dub ‘warrant*’) is the conjunctive property being warranted and true . I show that this implication of fallibilism conflicts with an uncontroversial thesis we have learned from reflection on Gettier cases: that nonaccidental truth is a constituent of warrant*. It follows that infallibilism is true. In the second part of the paper, I present and criticize a new argument against infallibilism. The argument states that there are plausible cases where, intuitively, the only thing that is keeping a belief from counting as knowledge is the falsity of that belief. Furthermore, it is plausible that such a belief is warranted and false. So, the argument goes, infallibilism is false. I show that this argument fails. (shrink)

In this paper we focus on transmission and failure of transmission of warrant. We identify three individually necessary and jointly sufficient conditions for transmission of warrant, and we show that their satisfaction grounds a number of interesting epistemic phenomena that have not been sufficiently appreciated in the literature. We then scrutinise Wright’s analysis of transmission failure and improve on extant readings of it. Nonetheless, we present a Bayesian counterexample that shows that Wright’s analysis is partially incoherent with our (...) analysis of warrant transmission and prima facie defective. We conclude exploring three alternative lines of reply: developing a more satisfactory account of transmission failure, which we outline; dismissing the Bayesian counterexample by rejecting some of its assumptions; reinterpreting Wright’s analysis to make it immune to the counterexample.

Recently, there has been much interest in epistemic roles of attention, especially in whether visual attention is necessary for warranting (basic) visual belief. Arguably it is not. But attention nevertheless has important roles to play in our warrant from vision. I argue that we must appeal to a competence for shifting visual attention in explaining transsaccadic vision and our epistemic warrant from it. So even if it is not necessary for visual warrant or vision, visual attention plays (...) a central role in both. (shrink)

A diagnostic process is an investigative process that takes a clinical picture as input and outputs a diagnosis. We propose a method for distinguishing diagnoses that are warranted from those that are not, based on the cognitive processes of which they are the outputs. Processes designed and vetted to reliably produce correct diagnoses will output what we shall call ‘warranted diagnoses’. The latter are diagnoses that should be trusted even if they later turn out to have been wrong. Our work (...) is based on the recently developed Cognitive Process Ontology and further develops the Ontology of General Medical Science. It also has applications in fields such as intelligence, forensics, and predictive maintenance, all of which rely on vetted processes designed to secure the reliability of their outputs. (shrink)

I critically examine two features of Plantinga’s Reformed Epistemology. (i) If basic theistic beliefs are threatened by defeaters (of various kinds) and thus must be defended by higher-order defeaters in order to remain rational and warranted, are they still “properly basic”? (ii) Does Plantinga’s overall account offer an argument that basic theistic beliefs actually are warranted? I answer both questions in the negative.

Scriptural Reasoning (SR) is a practice of philosophic theology that is offered as a rationally warranted albeit fallible response to the inadequacies of modern liberal and anti-liberal theologies whether they are adopted as academic projects or as dimensions of lived religious practice. In terms of everyday religious practice in the West today, SR may be characterized as an effort, at once, to help protect Abrahamic folk traditions (that is, of Christianity, Judaism, and Islam) from the cultural and theological effects of (...) residual western colonialism and to help protect religiously pluralist societies in the West from reactionary, anti-modern movements within these traditions. In the terms of recent academic discourse in theology, SR may be characterized as pragmatic, postliberal, scriptural, and inter-Abrahamic. SR may be labeled “pragmatic,” because it employs philosophic reasoning only to identify problems in its practitioners’ communities of everyday practice and in the institutions that are expected to repair them. SR may be labeled “postliberal,” because it emerges as a response to problems in the projects of modern, liberal theology, in particular this theology’s inadequate attention to problems in everyday practice. At the same time, SR is equally critical of anti-liberal theologies, or those that, rejecting the autonomy of human reason, argue for the opposite: grounding all projects of reasoning on a practice of “Christian reasoning” per se (or, comparably, of other confession-grounded reasonings).

Alvin Plantinga’s theory of knowledge, as developed in his Warrant trilogy, has shaped the debates surrounding many areas in epistemology in profound ways. Plantinga has received his share of criticism, however, particularly in his treatment of belief in God as being “properly basic”. There has also been much confusion surrounding his notions of warrant and proper function, to which Plantinga has responded numerous times. Many critics remain unsatisfied, while others have developed alternative understandings of warrant in order (...) to rescue Plantinga’s theory from certain objections. The most promising of such attempts fall under the broad category of “virtue epistemology” or a “virtue-theoretic” approach. The work being done in virtue epistemology is still in its early stages and a consensus on what actually constitutes virtue epistemology has yet to be reached. While some have attempted to structure an entire theory of knowledge based on the virtues possessed by the knower, others have focused more on the role of epistemic virtues as an attempt to supplement existing theories, including Plantinga’s. In this paper, I will offer an analysis of what such an attempt might look like and evaluate the potential success of broadening Plantinga’s original model. -/- My proposal is that certain features of a virtue-theoretic approach (also referred to as “agent-reliabilism”) could improve Plantinga’s model in significant ways. Not only would such a broadened approach be better equipped to handle common objections, but it would also be better suited to contribute an enhanced understanding of the task of epistemology, one that seeks to discover multiple epistemic goods other than what has been traditionally confined to the realm of knowledge. I conclude by applying this approach to Plantinga’s treatment of theistic belief in Warranted Christian Belief and by articulating a few of the ways in which epistemic virtues can increase the degree of warrant enjoyed by such belief. (shrink)

Extending Alvin Plantinga’s model of warranted belief to the beliefs of groups as a whole, I argue that if the dogmatic beliefs of the Catholic Church are true, they are also warranted. Catholic dogmas are warranted because they meet the three conditions of my model: they are formed (1) by ministers functioning properly (2) in accordance with a design plan that is oriented towards truth and reliable (3) in a social environment sufficiently similar to that for which they were designed. (...) I show that according to Catholic doctrine the authoritative spokespersons of the Church—ecumenical councils and popes—meet these conditions when defining dogmas. I also respond to the objection that the warrant of Catholic dogmas is defeated by the plurality of non-Catholic Christian sects that deny Catholic dogmas. (shrink)

Many philosophers agree that there is an epistemic norm governing action. However, they disagree on what this norm is. It has been observed that the word ‘know’ is prominent in ordinary epistemic evaluations of actions. Any opponent of the knowledge norm must provide an explanation of this fact. Gerken has recently proposed the most developed explanation. It invokes the hypothesis that, in normal contexts, knowledge-level warrant is frequently necessary and very frequently sufficient (Normal Coincidence), so that knowledge-based assessments would (...) be a good heuristic for practical reasoning and epistemic evaluations of action. In this paper, I raise three problems for this approach. First, I argue that Normal Coincidence is ad hoc: it relies on an unsupported frequency hypothesis that we should expect to be false given the warrant account that Gerken also endorses. Second, I argue that, in any case, Normal Coincidence is insufficient to support the hypothesis that knowledge-based evaluation of action constitutes a good heuristic. Third, I consider three other hypotheses close to Normal Coincidence apparently more likely to support the heuristic hypothesis, but I argue that they seem even more ad hoc than Normal Coincidence.

Contemporary reasoning about health is infused with the work products of experts, and expert reasoning about health itself is an active site for invention and design. Building on Toulmin’s largely undeveloped ideas on field-dependence, we argue that expert fields can develop new inference rules that, together with the backing they require, become accepted ways of drawing and defending conclusions. The new inference rules themselves function as warrants, and we introduce the term “warranting device” to refer to an assembly of the (...) rule plus whatever material, procedural, and institutional resources are required to assure its dependability. We present a case study on the Cochrane Review, a new method for synthesizing evidence across large numbers of scientific studies. After reviewing the evolution and current structure of the device, we discuss the distinctive kinds of critical questions that may be raised around Cochrane Reviews, both within the expert field and beyond. Although Toulmin’s theory of field-dependence is often criticized for its relativism, we find that, as a matter of practical fact, field-specific warrants do not enjoy immunity from external critique. On the contrary, they can be opened to evaluation and critique from any interested perspective. (shrink)

This paper presents a paradox based on the following assumptions: that emotions are warranted when you are justified in thinking that the emotion is fitting, that there are warranted cases of past-directed fear, that fear is fitting in the face of its formal object: dangerousness, and that this formal object consists in a probability of damage or harm to something of value. The paper then discusses three likely solutions: (1) denying that past-directed fear can be warranted, (2) using an alternative (...) formulation of fear's formal object, and (3) giving up warrant as justified as fittingness. Finally, it provides a case for the third solution and presents a warrant-based approach to fittingness and the appropriateness of emotions in general. (shrink)

In 'Perceptual Entitlement' (PPR 2003), Tyler Burge argues that on his teleological reliabilist account of perceptual warrant, warrant will persist in non-normal conditions, even radical skeptical scenarios like demon worlds. This paper explains why Burge's explanation falls short. But if we distinguish two grades of warrant, we can explain, in proper functionalist, teleological reliabilist terms, why warrant should persist in demon worlds. A normally functioning belief-forming process confers warrant in all worlds, provided it is reliable (...) in normal conditions when functioning normally. The first grade requires normal functioning. The second grade also requires being situated in normal conditions. (shrink)

The Proper Functionist account of warrant – like many otherexternalist accounts – is vulnerable to certain Gettier-style counterexamples involving accidentally true beliefs. In this paper, I briefly survey the development of the account, noting the way it was altered in response to such counterexamples. I then argue that Alvin Plantinga's latest amendment to the account is flawed insofar as it rules out cases of true beliefs which do intuitively strike us as knowledge, and that a conjecture recently put forward (...) by Thomas Crisp is also defective. I conclude by presenting my own suggestion as to how the account can be made less vulnerable to counterexamples involving accidentally true beliefs. Although I stay within the confines of Proper Functionism here, I think that my proposal (modulo a few details) could be attached to other externalist accounts of warrant as well. -/- . (shrink)

Wright's _Truth and Objectivity_ seeks to systematise a variety of anti-realist positions. I argue that many objections to the system are avoided by transposing its talk of truth into talk of warrant. However, a problem remains about debates involving 'direction-of-fit'. -/- Dummett introduced 'anti-realism' as a philosophical view informed by mathematical intuitionism. Subsequently, the term has been associated with many debates, ancient and modern. _Truth and Objectivity_ proposes that truth admits of different characteristics; these various debates then concern which (...) characteristics truth has, in a given area. This pluralism of truth is at odds with deflationism. I find fault with Wright's argument against deflationism. However, transmission of warrant across the Disquotational Schema suffices to ground Wright's proposal, which survives as a pluralism of classes of warrant. -/- The two main debates concern whether truths are always knowable (Epistemic Constraint) and whether disagreements in an area must be down to some fault of one of those involved (Cognitive Command). I introduce Assertoric Constraint, relating to Epistemic Constraint, where truths cannot outstrip the availability of warrant for their assertion. I solve a structural problem by a comparison with a constitutive analysis of Moore's Paradox. The relativism of blameless disagreement is problematic. Wright's response invokes a sort of ignorance which he calls `Quandary'. I criticise this before proposing an alternative. -/- I agree with Wright that Dummett's original anti-realism does not belong among the positions which Wright seeks to systematise. However, two candidates show that the proposal suffers a weakness. Wright thinks Expressivism misguided, and implicitly rules out his earlier non-cognitivism about necessity. I argue that Expressivism has promise, and I endorse Wright's Cautious Man argument for non-cognitivism about necessity; both involve play with `direction-of-fit'. I conclude that this sort of anti-realist debate needs to be accommodated by the proposal. (shrink)

Contextualists offer "high-low standards" practical cases to show that a variety of knowledge standards are in play in different ordinary contexts. These cases show nothing of the sort, I maintain. However Keith DeRose gives an ingenious argument that standards for knowledge do go up in high-stakes cases. According to the knowledge account of assertion (Kn), only knowledge warrants assertion. Kn combined with the context sensitivity of assertability yields contextualism about knowledge. But is Kn correct? I offer a rival account of (...) warranted assertion and argue that it beats Kn as a response to the "knowledge" version of Moore's Paradox. (shrink)

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of this (...) paper is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

In my 1991 paper, AAnti-Individualism and Privileged Access,@ I argued that externalism in the philosophy of mind is incompatible with the thesis that we have privileged , nonempirical access to the contents of our own thoughts.¹ One of the most interesting responses to my argument has been that of Martin Davies (1998, 2000, and Chapter _ above) and Crispin Wright (2000 and Chapter _ above), who describe several types of cases to show that warrant for a premise does not (...) always transmit to a known deductive consequence of that premise, and who contend that this fact under-mines my argument for incompatibilism. I will try to show here that the Davies/Wright point about transmission of warrant does not adversely affect my argument. (shrink)

In what follows, I appeal to Charles Babbage’s discussion of the division of mental labor to provide evidence that—at least with respect to the social acquisition, storage, retrieval, and transmission of knowledge—epistemologists have, for a broad range of phenomena of crucial importance to actual knowers in their epistemic practices in everyday life, failed adequately to appreciate the significance of socially distributed cognition. If the discussion here is successful, I will have demonstrated that a particular presumption widely held within the contemporary (...) discussion of the epistemology of testimony—a presumption that I will term the personalist requirement—fails to account for those very practices of knowers that I detail here. I will then conclude by suggesting that an alternate account of testimonial warrant, one that has heretofore been underappreciated, ought to be given more serious consideration—in particular because it is well suited to account for those actual practices of knowers that the personalist requirement leaves unrecognized.

My aim in this paper is to critically assess two opposing theses about the epistemology of religious belief. The first one, developed by John Mackie, claims that belief in God can be justified or warranted only if there is a good argument for the existence of God. The second thesis, elaborated by Alvin Plantinga, holds that even if there is no such argument, belief in God can be justified or warranted. I contend that the first thesis is plausibly false, because (...) belief in God is not just like a scientific hypothesis, and the second thesis is likely true if epistemic externalism is the correct view. However, even if the second thesis is true, I argue that to work on good arguments for God’s existence is unavoidable in order to cope with a new version of the Great Pumpkin objection, as well as to achieve other relevant purposes such as to convince rational observers outside the theistic community that belief in God is likely justified or warranted.

Alvin Plantinga’s Warrant and Proper Function gives two major definitions of warrant. One states that reliable cognitive faculties aimed at true belief and functioning properly in the right environment are necessary and sufficient for warrant; the other definition only states that they are necessary. The latter definition is the more important one. There are different kinds of knowledge, and justification is necessary for some beliefs to be warranted. Even a belief warranted by proper function can receive a (...) higher degree of warrant by justification. This implies that natural theology has a useful role within the contours of a Plantingian epistemology. (Please note that the pagination here does not match the pagination in the published edition.).

Contextualists and pragmatists agree that knowledge-denying sentences are contextually variable, in the sense that a knowledge-denying sentence might semantically express a false proposition in one context and a true proposition in another context, without any change in the properties traditionally viewed as necessary for knowledge. Minimalists deny both pragmatism and contextualism, and maintain that knowledge-denying sentences are not contextually variable. To defend their view from cases like DeRose and Stanley's high stakes bank case, minimalists like Patrick Rysiew, Jessica Brown, and (...) Wayne Davis forward ‘warranted assertability maneuvers.’ The basic idea is that some knowledge-denying sentence seems contextually variable because we mistake what a speaker pragmatically conveys by uttering that sentence for what she literally says by uttering that sentence. In this paper, I raise problems for the warranted assertability maneuvers of Rysiew, Brown, and Davis, and then present a warranted assertability maneuver that should succeed if any warranted assertability maneuver will succeed. I then show how my warranted assertability maneuver fails, and how the problem with my warranted assertability maneuver generalizes to pragmatic responses in general. The upshot of my argument is that, in order to defend their view from cases like DeRose and Stanley's high stakes bank case, minimalists must prioritize the epistemological question whether the subjects in those cases know over linguistic questions about the pragmatics of various knowledge-denying sentences.

Investigating an actual case that occurred in a New York state hospital where an Orthodox Jewish patient’s legal proxy demands that the clinicians and hospital administrators should provide aggressive treatment with all available technological resources for the seemingly brain-dead patient with a medically futile condition.

Otherwise, we will be allowing society to issue a carte blanche to religious autonomy (...) by technology abuse. It is argued that religious autonomy should be restricted when its demand exhibits apparent logical absurdity and/or goes against the common survival of the entire population. (shrink)

Throughout the debate on psi, skeptics have almost universally insisted on different standards for evaluating the evidence, claiming that psi represents a radical departure from our current scientific understanding. Thus, there is considerable ambiguity about what standard of evaluation psi must meet. Little attention has been paid to the possible harm to the integrity of scientific investigation from this resulting inconsistency in testing standards. Some have proposed using a Bayesian framework as an improvement on this dilemma in order to more (...) explicitly model beliefs, assumptions, and background scientific knowledge, especially when evaluating a controversial hypothesis. Recently, Kuhn’s notion of paradigms, which constrains scientific research within bound- aries believed to be most productive, has been incorporated into a Bayesian framework. Within this framework, I explore a likely paradigm or meta-theory used by skeptics that typically constrains research and makes it difficult for psi evidence to be accepted. It appears that such a paradigm would in many respects have difficulty accounting for consciousness, which is fundamental to an understanding of psi. I discuss why psi data are likely to play a key role in making progress in solving the problem of consciousness. Thus, applying different standards of evaluation to psi data is likely counterproductive. (shrink)

This article presents Alvin Plantinga’s views on epistemic justification. The first part situates Plantinga’s epistemological views in the context of his epistemology of religion and debates of general epistemology. The second part discusses Plantinga’s argument that the internalism of 20th century epistemology stems from deontologism and that the views on the epistemic justification of analytic philosophers reflect the relationship between classical deontologism and classical internalism. The last part points to the objections with which the Plantinga’s conception met and tries to (...) balance the depth and weakness of its position. (shrink)

Steven Hales and Jennifer Johnson—building off their (2014) work as well as Hales (2015, 2016)—have recently conducted two studies in Philosophical Psychology (2018) that show that there is a relationship between optimism and folk assessments of luck. Hales and Johnson use these results to argue that there is no such thing as luck. Instead, they claim that the concept is highly subjective and a cognitive illusion and that what we are in need of is an error theory. After reviewing Hales (...) and Johnson’s position, I levy four objections against their view. First, they ignore the fact that luck involves a chanciness condition. Second, their standards for what it means to be a useful philosophical theory are too high. Third, their view ignores the fact that there are various accounts of value in the literature and assumes a kind of relativism that few people would be willing to accept. Lastly, their error theory is not supported by the empirical evidence. Because of these problems, Hales and Johnson’s argument is not a serious threat to extant accounts of luck. (shrink)

No. More carefully: apparently not. [This piece was published in the Routledge Handbook of Metaphysical Ground (2020), edited by Michael J. Raven with the title "Anti-Skeptical Rejoinders", pp. 180-193].

The ongoing debates about what rationality consists in remain unsettled and leave plenty of interpretation for what is rational in belief formation and action. Hinman risks a large step in seeming to assume that it is rational not to contravene scientific theories and findings and irrational to disallow this openness. These -- possibilities lending a potential for deistic beliefs not to be inconsistent with rationality. The presumed scientific approach to allowing a rationality in such belief revolves around the development of (...) the so-called "M-scale" in the psychology of belief. The other, even more intense, global debate here is whether such an approach to rationality and rational belief is indeed valid, that is, the ongoing concen of whether such belief is consistent or not with scientific practice, understanding, and method. Readers interested in these debates should be interested in this unusual work and its purports. (shrink)

Proper functionalism explicates epistemic warrant in terms of the function and normal functioning of the belief-forming process. There are two standard substantive views of the sources of functions in the literature in epistemology: God (intelligent design) or Mother Nature (evolution by natural selection). Both appear to confront the Swampman objection: couldn’t there be a mind with warranted beliefs neither designed by God nor the product of evolution by natural selection? Is there another substantive view that avoids the Swampman objection? (...) There are two. The first is the generalized selected-effects theory of functions. The second is the organizational theory of functions. Both, however, require some history to assign functions, for both are etiological theories of functions: past effects help explain current function. Swampman can then acquire functions, perhaps soon after creation, though he has none at the moment of inception. (shrink)

According to an intuition highly popular in Western world, beliefs, includ-ing religious beliefs, must be supported by sufficient evidence in order to be held in a rational (or justified) way (evidentialism). Plantinga for-mulates his own view about the rationality of religious beliefs, which he considers as opposite to the traditional view. The central thesis of his position is that religious beliefs are perfectly rational when believed in the basic way, that is without any evidence or argument and even with-out the (...) use of natural reason at all. According to Plantinga people could have acquired their religious beliefs via extraordinary cognitive faculty, which he calls, after Calvin, sensus divinitatis. In this paper I ask a ques-tion whether Plantinga successfully rejects traditional intuition about the need of natural reason for religious beliefs. For this purpose, I first refer to Plantinga’s understanding of the traditional concept of the rationality of religious beliefs. I then summarize Plantinga’s views on the third condi-tion of knowledge and his account of the rationality of religious beliefs. Next, I turn to the critical part of the article. I point out the inadequacy of Plantinga’s position. To do so I first analyze and criticize Plantinga’s argument for the view that possessing sufficient evidence for religious beliefs is not an epistemic duty. I argue that Plantinga rejects only one understanding of that requirement and this is not enough to reject the whole idea of evidentialism. Then, I criticize Plantinga’s position on the third condition of knowledge, which he calls warrant. To this end I recall Laurence BonJour’s argument against externalism, since my critique of Plantinga’s position is analogous to BonJour’s argument. If my critique is successful then it is not that religious belief could be held in rational way without the use of natural reason, because in this case subject would be epistemically irresponsible.

In his recent book Warranted Christian Belief (2000), Alvin Plantinga argues that the defender of naturalistic evolution is faced with adefeater for his position: as products of naturalistic evolution, we have no way of knowing if our cognitive faculties are in fact reliably aimed at the truth. This defeater is successfully avoided by the theist in that, given theism, we can be reasonably secure that out cognitive faculties are indeed reliable. I argue that Plantinga’s argument is ultimately based on a (...) faulty comparison, that he is comparing naturalistic evolution generally to one particular model of theism. In light of this analysis, the two models either stand or fall together with respect to the defeater that Plantinga offers. (shrink)

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly (...) designed, or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

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)

Conspiracy theories and conspiracy theorists have been accused of a great many sins, but are the conspiracy theories conspiracy theorists believe epistemically problematic? Well, according to some recent work, yes, they are. Yet a number of other philosophers like Brian L. Keeley, Charles Pigden, Kurtis Hagen, Lee Basham, and the like have argued ‘No!’ I will argue that there are features of certain conspiracy theories which license suspicion of such theories. I will also argue that these features only license a (...) limited suspicion of these conspiracy theories, and thus we need to be careful about generalising from such suspicions to a view of the warrant of conspiracy theories more generally. To understand why, we need to get to the bottom of what exactly makes us suspicious of certain conspiracy theories, and how being suspicious of a conspiracy theory does not always tell us anything about how likely the theory in question is to be false.

Infallibilism is the view that a belief cannot be at once warranted and false. In this essay we assess three nonpartisan arguments for infallibilism, arguments that do not depend on a prior commitment to some substantive theory of warrant. Three premises, one from each argument, are most significant: (1) if a belief can be at once warranted and false, then the Gettier Problem cannot be solved; (2) if a belief can be at once warranted and false, then its (...) class='Hi'>warrant can be transferred to an accidentally true belief; (3) if a belief can be at once warranted and false, then it can be warranted and accidentally true. We argue that each of these is either false or no more plausible than its denial. Along the way, we offer a solution to the Gettier Problem that is compatible with fallibilism. (shrink)

A background assumption of this paper is that the repertoire of inference schemes available to humanity is not fixed, but subject to change as new schemes are invented or refined and as old ones are obsolesced or abandoned. This is particularly visible in areas like health and environmental sciences, where enormous societal investment has been made in finding ways to reach more dependable conclusions. Computational modeling of argumentation, at least for the discourse in expert fields, will require the possibility of (...) modeling change in a stock of schemes that may be applied to generate conclusions from data. We examine Randomized Clinical Trial, an inference scheme established within medical science in the mid-20th Century, and show that its successful defense by means of practical reasoning allowed for its black-boxing as an inference scheme that generates (and warrants belief in) conclusions about the effects of medical treatments. Modeling the use of a scheme is well-understood; here we focus on modeling how the scheme comes to be established so that it is available for use. (shrink)

Paper reconstructs three different accounts of the rationality of religious belief that we found in Plantinga's epistemology of theistic and religious belief. Taken into account are works (papers and books) from GAOM to first two books about a warrant. In the end, the article formulates some questions about rationality and evaluation of the importance of property of rationality of religious belief concerning other positive epistemic statuses.

This paper is about two topics: metaepistemological absolutism and the epistemic principles governing perceptual warrant. Our aim is to highlight—by taking the debate between dogmatists and conservativists about perceptual warrant as a case study—a surprising and hitherto unnoticed problem with metaepistemological absolutism, at least as it has been influentially defended by Paul Boghossian as the principal metaepistemological contrast point to relativism. What we find is that the metaepistemological commitments at play on both sides of this dogmatism/conservativism debate do (...) not line up with epistemic relativism nor do they line up with absolutism, at least as Boghossian articulates this position. What this case study reveals is the need in metaepistemological option space for the recognition of a weaker and less tendentious form of absolutism, what we call “environment relativism”. On this view, epistemic principles are knowable, objective, and they can serve as the basis of particular epistemic evaluations, but their validity is relative to the wider global environment in which they are applied.

The concept of epistemic defeat or defeasibility has come to occupy an important place in contemporary epistemology, especially in relation to the closely allied concepts of justified belief, warrant, and knowledge. These allied concepts signify positive epistemic appraisal or positive epistemic status. As a first approximation, defeasibility refers to a belief’s liability to lose some positive epistemic status, or to having this status downgraded in some particular way. For example, a person may be epistemically justified in believing some proposition (...) p at one time, but then the belief might become less justified or even unjustified at some later time. Moreover, beliefs may also be prevented from having or acquiring some positive epistemic status in the first place. So more generally, defeasibility refers to a kind of epistemic liability or vulnerability, the potential of loss, reduction, or prevention of some positive epistemic status. A defeater is, broadly speaking, a condition that actualizes this potential. This article begins by outlining two general types of defeaters: propositional defeaters and mental state defeaters. Propositional defeaters are conditions external to the perspective of the cognizer that prevent an overall justified true belief from counting as knowledge. Mental state defeaters are conditions internal to the perspective of the cognizer (such as experiences, beliefs, withholdings) that cancel, reduce, or even prevent justification. (shrink)

The paper gives an a priori argument for the view that knowledge is unanalysable. To establish this conclusion I argue that warrant, i.e. the property, whatever precisely it is, which makes the difference between knowledge and mere true belief, entails both truth and belief and thus does not exist as a property distinct from knowledge: all and only knowledge can turn a true belief into knowledge. The paper concludes that the project of trying to find a condition distinct from (...) knowledge that is necessary and together with truth and belief sufficient for knowledge must be doomed to failure.

Tyler Burge first introduced his distinction between epistemic entitlement and epistemic justification in ‘Content Preservation’ in 1993. He has since deployed the distinction in over twenty papers, changing his formulation around 2009. His distinction and its basis, however, is not well understood in the literature. This chapter distinguishes two uses of ‘entitlement’ in Burge, and then focuses on his distinction between justification and entitlement, two forms of warrant, where warrants consists in the exercise of a reliable belief-forming competence. Since (...) he draws the distinction in terms of reasons, this chapter brings his account of reasons altogether in one place. The chapter introduces a decision-procedure for classifying warrants as justifications or entitlements. The distinction between justification and entitlement is not the same as the inferential vs. non-inferential distinction. The chapter distinguishes inference from processing, thinking, reasoning, and critically reasoning. Burge’s new formulation of the distinction was driven by the recognition of non-accessible modular reasons. Three kinds of access are distinguished. (shrink)

Crispin Wright has given an explanation of how a first time warrant can fall short of transmitting across a known entailment. Formal epistemologists have struggled to turn Wright’s informal explanation into cogent Bayesian reasoning. In this paper, I analyse two Bayesian models of Wright’s account respectively proposed by Samir Okasha and Jake Chandler. I argue that both formalizations are unsatisfactory for different reasons, and I lay down a third Bayesian model that appears to me to capture the valid kernel (...) of Wright’s explanation. After this, I consider a recent development in Wright’s account of transmission failure. Wright suggests that his condition sufficient for transmission failure of first time warrant also suffices for transmission failure of supplementary warrant. I propose an interpretation of Wright’s suggestion that shield it from objections. I then lay down a fourth Bayesian framework that provides a simplified model of the unified explanation of transmission failure envisaged by Wright. (shrink)

Recently, Erik Baldwin and Tyler McNabb have brought Madhva's epistemological framework into active dialogue with Alvin Plantinga's religious epistemology and have argued that individuals within Madhva's tradition cannot make full use of Plantinga's epistemology, according to which, Christian belief resists de jure objections and can also have warrant. While I do not contest this specific claim, I demonstrate that an analysis of Madhva's epistemological framework reveals that this framework has its own resources through which it can resist de jure (...) objections. I address various objections to the rationality of Mādhvic belief and conclude that there are no de jure objections to Mādhvic belief that are independent of de facto objections. (shrink)

Charles Sanders Peirce has commonly been interpreted as a proponent of an epistemic theory of truth. Such a theory has the apparent advantage of directly undercutting radical skepticism, but the disadvantage of implausibly entailing that there are no truths concerning irretrievably lost facts. Recently Andrew Howat has defended Peirce’s epistemic constraint on truth by recasting Peirce’s claim that all truths would be believed following sufficient inquiry, not as constitutive of truth, but as a Wittgensteinian hinge proposition. I begin with a (...) twofold historical reply to Howat: first, Peirce can at least plausibly be read as claiming that the claim in question is analytic of the concept <truth>; and second, while Peirce did think we must accept without evidence the further claim that there are any truths (so characterized), he regarded this further claim not as a Wittgensteinian hinge but as a reasonable hope. I then substantively defend the latter Peircean proposal, arguing that hopes, as against beliefs, are chiefly warranted pragmatically, and so can be warranted even to a sufficient level to render them properly action-guiding in cases where belief in the same proposition would remain unjustified. I conclude by suggesting, first, that this proposal is superior to Wittgenstein’s own epistemology in evading psychologism, and second, that it attractively vindicates the reasonableness of inquiry on Peircean grounds that don’t require an appeal to an implausible epistemic theory of truth.

Under the influence of Hilary Putnam’s collapse of the fact/value dichotomy, a resurging approach that challenges the movements of American pragmatism and discourse ethics, I tease out in the first section of my paper the demand for the warranted assertibility hypothesis in Putnam’s sense that may be possible, relying on moral realism to get rid of ‘rampant Platonism’. Tracing back to ‘communicative action’ or the Habermasian way that puts forward the reciprocal understanding of discourse instigates the idea of life-world as (...) composed of ‘culturally transmitted and linguistically organized stock of interpretative patterns’, this section looks for whether Habermas’ psychoanalysis of prolonged discussion can accord with Putnam’s thick ethical terms or not. The last section of the paper pitfalls Putnam’s stance to accepting Habermas’ ‘discourse ethics’ that centers around the context of entangling ‘rational thoughts’ to ‘communication’, but he introduces the idea of fallibilism in a rational query that also attacks the Habermasian metaphysical idea of the validity of ethical statements that goes towards the truth. My next attempt is to see whether Putnam’s objective dictum towards morality that resonates the collapse of fact/value dichotomy from a universalistic stand can successfully evade Rorty’s naive realism and Habermas’ ‘sociologism about values’ respectively. This sort of claim insists on a universalizable pattern of culture-relative value. I consider that the idea of a fact/value dichotomy engages with the inextricable entanglement between the normative and descriptive content, besides the epistemic values having exclusively intertwined with the structure of factual discourse that intends towards collapsing the fact/value dichotomy, a subjective universalizability predilection.

Tyler Burge famously argues in his 1993 paper "Content Preservation" that it is not only a priori true that we enjoy a prima facie warrant to take what others assert as true, but also that there our warrant to believe what we are told in certain special cases is a priori. So just as our warrant for believing certain mathematical truths might be a priori, so too there are cases of belief through testimony that are a priori. (...) Then in a 2013 Postscript to "Content Preservation" he took it all back. All of Burge's ideas and arguments for and against are interesting and important, and deepen our understanding of testimony, comprehension, warrant, and the a priori. But his ideas and arguments are hard to understand. This paper explains all of ideas and arguments, both for and against, in a clear and comprehensive way. Along the way, Anna-Sara Malmgren's interpretation and criticism of Burge's position is also expounded and criticized. (shrink)

My aim in this paper is to show that some parts of J. M. Bocheński’s account of the logic of religion are useful for epistemological investigation of a religious belief, particularly for the questions of realistic and cognitive interpretations of a religious discourse, the problems of justification and warrant of a religious belief and for the problem of the place of criticism in a religious discourse. Referring to Bocheński's understanding of the structure of religious/theological thinking, I present the criteria (...) for the gradual rationality of religion and claim that religions may differ in rationality and that there may be a rational and critical religion that uses the achievements of science and philosophy - contrary to what the New Atheists claim.
