For Kant, knowledge involves certainty. If “certainty” requires that the grounds for a given propositional attitude guarantee its truth, then this is an infallibilist view of epistemic justification. Such a view says you can’t have epistemic justification for an attitude unless the attitude is also true. Here I want to defend an alternative fallibilist interpretation. Even if a subject has grounds that would be sufficient for knowledge if the proposition were true, the proposition might not be true. And so there (...) is sometimes still rational room for doubt. The goal of this paper is to present four different models of what “certainty” amounts to, for Kant, each of which is compatible with fallibilism. (shrink)

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

A distinctive feature of Juan Comesaña's epistemological account is the possibility of an agent possessing a false proposition as evidence. Comesaña argues that there are a number of theoretical virtues of his account once we accept this possibility, however, one might expect that there are particular vices of his account as well. Littlejohn and Dutant (2021) claim that a reflective agent who accepts Comesaña's view is rationally compelled to update their credences differently than unreflective agents, or else they will be (...) guilty of a problematic kind of doublethink: evidence in general can be false, but my evidence is never false. I argue that parallel reasoning applies to any epistemological view that says that it is possible for a rational agent to be wrong about what their evidence is. When a rational agent reflectively accepts that they could be wrong about their evidence they are rationally compelled to update their credences differently than unreflective agents, or else they will be guilty of a problematic kind of doublethink: even though rational agents in general are wrong about their evidence, I'm never wrong about my evidence. Reflecting on a particular challenge to Comesaña's view ultimately reveals a general challenge to fallibilism. (shrink)

This paper outlines a new type of skepticism that is both compatible with fallibilism and supported by work in psychology. In particular, I will argue that we often cannot properly trust our ability to rationally evaluate reasons, arguments, and evidence (a fundamental knowledge-seeking faculty). We humans are just too cognitively impaired to achieve even fallible knowledge, at least for many beliefs.

Hope, in its propositional construction "I hope that p," is compatible with a stated chance for the speaker that not-p. On fallibilist construals of knowledge, knowledge is compatible with a chance of being wrong, such that one can know that p even though there is an epistemic chance for one that not-p. But self-ascriptions of propositional hope that p seem to be incompatible, in some sense, with self-ascriptions of knowing whether p. Data from conjoining hope self-ascription with outright assertions, with (...) first- and third-person knowledge ascriptions, and with factive predicates suggest a problem: when combined with a plausible principle on the rationality of hope, they suggest that fallibilism is false. By contrast, the infallibilist about knowledge can straightforwardly explain why knowledge would be incompatible with hope, and can offer a simple and unified explanation of all the linguistic data introduced here. This suggests that fallibilists bear an explanatory burden which has been hitherto overlooked. (shrink)

Alex Worsnip argues in favor of what he describes as a particularly robust version of fallibilism: subjects can sometimes know things that are, for them, possibly false (in the epistemic sense of 'possible'). My aim in this paper is to show that Worsnip’s argument is inconclusive for a surprising reason: the existence of possibly false knowledge turns on how we ought to model entailment or consequence relations among sentences in natural language. Since it is an open question how we (...) ought to think about consequence in natural language, it is an open question whether there is possibly false knowledge. I close with some reflections on the relation between possibly false knowledge and fallibilism. I argue that there is no straightforward way to use linguistic data about natural language epistemic modals to either verify or refute the fallibilist thesis. (shrink)

According to the received view, genuine mathematical justification derives from proofs. In this article, I challenge this view. First, I sketch a notion of proof that cannot be reduced to deduction from the axioms but rather is tailored to human agents. Secondly, I identify a tension between the received view and mathematical practice. In some cases, cognitively diligent, well-functioning mathematicians go wrong. In these cases, it is plausible to think that proof sets the bar for justification too high. I then (...) propose a fallibilist account of mathematical justification. I show that the main function of mathematical justification is to guarantee that the mathematical community can correct the errors that inevitably arise from our fallible practices. (shrink)

Fallibilism, as a fundamental aspect of pragmatic epistemology, can be illuminated by a study of law. Before he became a famous American judge, Oliver Wendell Holmes, Jr., along with his friends William James and Charles Sanders Peirce, associated as presumptive members of the Metaphysical Club of Cambridge in the 1870s, recalled as the birthplace of pragmatism. As a young scholar, Holmes advanced a concept of legal fallibilism as incremental community inquiry. In this early work, I suggest that Holmes (...) treats common law cases more like scientific experiments than as deductive applications of already clear rules. Common law rules may be seen as a product of 1) the conflicts that occur in society, 2) the channeling of conflicts into legal disputes, 3) the gradual accumulation of judicial decisions classified into groups, and 4) the development of consensual understanding, expressed in rules and principles, as to how future cases should be classified and decided. This does not involve only lawyers and judges. Especially in controversial cases, it may indirectly involve an entire community. The legal process is seen as an extended intergenerational process of inquiry. It illuminates the relation of thought, expression, and conduct among a community of inquirers, applied to the problems of social ordering. (shrink)

The relation of scepticism to infallibilism and fallibilism is a contested issue. In this paper I argue that Cartesian sceptical arguments, i.e. sceptical arguments resting on sceptical scenarios, are neither tied to infallibilism nor collapse into fallibilism. I interpret the distinction between scepticism and fallibilism as a scope distinction. According to fallibilism, each belief could be false, but according to scepticism all beliefs could be false at the same time. However, to put this distinction to work (...) sceptical scenarios have to be understood as ignorance-possibilities, not as error-possibilities. To show that scepticism is not tied to infallibilism I reject the principle of unrestricted relevance according to which any error- or ignorance-possibility whatsoever is relevant. Instead I argue that the sceptic should distinguish between local and global ignorance-possibilities. Global ignorance-possibilities are relevant even though not all ignorance-possibilities are relevant. The result is a refined version of the Cartesian sceptical argument that avoids two traps other versions do not avoid. (shrink)

Much discussion of meaning by philosophers over the last 300 years has been predicated on a Cartesian first-person authority (i.e. “infallibilism”) with respect to what one’s terms mean. However this has problems making sense of the way the meanings of scientific terms develop, an increase in scientific knowledge over and above scientists’ ability to quantify over new entities. Although a recent conspicuous embrace of rigid designation has broken up traditional meaning-infallibilism to some extent, this new dimension to the meaning of (...) terms such as “water” is yet to receive a principled epistemological undergirding (beyond the deliverances of “intuition” with respect to certain somewhat unusual possible worlds). Charles Peirce’s distinctive, naturalistic philosophy of language is mined to provide a more thoroughly fallibilist, and thus more realist, approach to meaning, with the requisite epistemology. Both his pragmatism and his triadic account of representation, it is argued, produce an original approach to meaning, analysing it in processual rather than objectual terms, and opening a distinction between “meaning for us”, the meaning a term has at any given time for any given community and “meaning simpliciter”. the way use of a given term develops over time (often due to a posteriori input from the world which is unable to be anticipated in advance). This account provocatively undermines a certain distinction between “semantics” and “ontology” which is often taken for granted in discussions of realism. (shrink)

The role of certitude in our mental lives is, to put it mildly, controversial. Many current epistemologists (including epistemologists of religion) eschew certitude altogether. Given his emphasis on certitude, some have maintained that John Henry Newman was an infallibilist about knowledge. In this paper, we argue that a careful examination of his thought (especially as seen in the Grammar of Assent) reveals that he was an epistemic fallibilist. We first clarify what we mean by fallibilism and infallibilism. Second, we (...) explain why some have read Newman as an infallibilist. Third, we offer two arguments that Newman is at least a fallibilist in a weak sense. In particular, the paradox he seeks to resolve in the Grammar and his dispute with John Locke both indicate that he is at least a weak fallibilist. We close with a consideration of whether Newman is a fallibilist in a much stronger sense as well. (shrink)

We presuppose a position of scientific realism to the effect (i) that the world exists and (ii) that through the working out of ever more sophisticated theories our scientific picture of reality will approximate ever more closely to the world as it really is. Against this background consider, now, the following question: 1. Do the empirical theories with the help of which we seek to approximate a good or true picture of reality rest on any non-empirical presuppositions? One can answer (...) this question with either a 'yes' or a 'no'. 'No' is the preferred answer of most contemporary methodologists -- Murray Rothbard is one distinguished counterexample to this trend -- who maintain that empirical theories are completely free of non-empirical ('a priori') admixtures and who see science as a matter of the gathering of pure 'data' obtained through simple observation. From such data scientific propositions are then supposed to be somehow capable of being established. (shrink)

This paper thematically analyzes Charles Sanders Peirce’s doctrine of fallibilism. Peirce’s fallibilism is best construed as an epistemic thesis that tries to correct the excesses of and mediate between Cartesian dogmatism and skepticism. Hence, as a theory of epistemic justification, it is neither overly confident like foundationalism nor overarchingly cynic like skepticism. It grants the possibility for knowledge, yet, this knowledge is not foregrounded on absolute warrants. The paper therefore argues that, it is at this juncture that the (...) theory runs into the problem of vagueness: if we are not certain at which particular point a given piece of information becomes knowledge, how can we know we have arrived at it yet? Subsequently, Peirce’s novel introduction of hope (as an epistemic principle) and the self-corrective nature of inquiry makes his theory more convincing. Thus, we do not need to worry about arriving at the knowledge, because doubt necessitates inquiry which in turn is self-corrective. So, the more the inquiry, the surer we are of arriving at knowledge. (shrink)

How, as Caldwell puts it, does one choose between rival systems all of which claim to rest on a priori foundations? On the nonfallibilistic conception it is difficult to make sense even of the possibility of rival systems of this sort. On the conception here defended, in contrast, the existence of such rival systems can be seen to be a perfectly natural and acceptable consequence of the just-mentioned difficulties we will often fact in coming to know even the intelligible traits (...) of reality: one adjudicates between such systems in the same way in which one adjudicates between all rival scientific hypotheses, namely via a complex mixture of empirical and a priori considerations.

Generally, an epistemic fallibilist considers it reasonable to claim, “I know that P, but I may be wrong.” An epistemic infallibilist, on the other hand, would consider this claim absurd. I argue initially that infallibilism presents more advantages in its assertion of the claim’s absurdity than fallibilism does in making the claim. One, infallibilism is not faulted with the propensity for violations of epistemic closure that beleaguers some fallibilist accounts, due in part to the latter’s problematic shunting of fallible (...) epistemic standards across inferential chains. Two, infallibilism is more easily modelled doxastically than fallibilism, as the former’s understanding of certainty is more tractable than the latter’s idea of what counts as a viable standard of fallibility. A rectification of these fallibilist issues may then be called upon to motivate gradualist variants of fallibilism. For epistemic gradualism, the problematic modellability and shunting of standards is curtailed via an awareness that the standard for knowledge is just one out of many along a gradient that includes, at one extreme, the infallibilist standard of certainty. Specifically, first, gradualism, along with infallibilism, can be modelled doxastically through elucidating upon an obtaining relation between doubt and knowledge; next, the problem with violating closure, although not generally applicable to infallibilism, can be answered by gradualism with a reasonable denial of closure altogether that makes precise which epistemic standard is relevant for which part of an inferential chain; lastly, these modelling resources can be appropriated, by both gradualism and infallibilism, to successfully address a doxastically pertinent form of closure violation called rational self-doubt.

This paper revisits the epistemological doctrine of fallibilism and discusses its overarching consequences to the whole structure of human knowledge and its extended applications. Fallibilism claims that we can never have absolute certainty to justify our knowledge claims. That means, knowledge needs not have an absolute, definitive warrants. Consequently, using the discursive method of enquiry, the paper argues that, if fallibilism is true, then, the concept of knowledge is redefined. Hence, knowledge would no longer mean the preclusion (...) of error but the contextual absence of doubt. Accordingly, knowledge in this schema, would only be an approximation [or even a verisimilitude] to the truth or a working tool for future progress so long as it serves the purposes of the present. It is the conclusion of the paper, that aside its apparent epistemic implications, fallibilism has also non-epistemic implications which ranges from a more general change in attitude towards our stances to a more applied and direct consequences in both legal, religious or moral enterprises of human endeavours.

A fallibilist theory of knowledge is employed to make sense of the idea that agents know what they are doing 'without observation' (as on Anscombe's theory of practical knowledge).

Many epistemologists call themselves ‘fallibilists’. But many philosophers of language hold that the meaning of epistemic usages of ‘possible’ ensures a close knowledge- possibility link : a subject’s utterance of ‘it’s possible that not-p’ is true only if the subject does not know that p. This seems to suggest that whatever the core insight behind fallibilism is, it can’t be that a subject could have knowledge which is, for them, possibly false. I argue that, on the contrary, subjects can (...) have such possibly false knowledge. My ultimate aim, then, is to vindicate a very robust form of fallibilism. Uniquely, however, the account I offer does this while also allowing that concessive knowledge attributions – sentences of the form “I know that p, but it’s possible that not-p” – are not only infelicitous but actually false whenever uttered. The account predicts this result without conceding KPL. I argue that my account has the resources to explain some related cases for which the KPL account yields the wrong predictions. Taken as a whole, the linguistic data not only do not support the proposal that subjects cannot have possibly false knowledge, but indeed positively favor the proposal that they can. (shrink)

George M. Searle (1839-1918) and Charles S. Peirce worked together in the Coast Survey and the Harvard Observatory during the decade of 1860: both scientists were assistants of Joseph Winlock, the director of the Observatory. When in 1868 George, a convert to Catholicism, left to enter the Paulist Fathers, he was replaced by his brother Arthur Searle. George was ordained as a priest in 1871, was a lecturer of Mathematics and Astronomy at the Catholic University of America, and became the (...) fourth superior general of his congregation from 1904 to 1909. Among the books he wrote for non-Catholic audiences was Plain Facts for Fair Minds (1895). On the 8th of August of 1895, Peirce found that book in a bookstore and the following day wrote a letter to George Searle developing his strong reservations about the question of the infallibility of the Pope. This letter (L 397) is almost unknown amongst Peirce's scholars. -/- After describing these historical circumstances as a framework, the aim of my paper is to describe Peirce's arguments against papal infallibility presented by George Searle in his book, and the contrast between the genuine scientific attitude and the putative metaphysical notion of absolute truth that is —according to Peirce— behind Searle's defense of infallibility. In this sense, Peirce's fallibilism will be explained with some detail, giving an account also of his practical infallibilism: "The assertion that every assertion but this is fallible, is the only one that is absolutely infallible. But though nothing else is absolutely infallible, many propositions are practically infallible; such as the dicta of conscience" (Minute Logic, CP 2.75, c. 1902). -/- Finally, having in mind the present interest in Peirce's religious ideas it will be suggested that some of Peirce's ideas on infallibility are nearer to contemporary understanding of that issue than Searle's defense. "I would with all my heart join the ancient church of Rome if I could. But your book," —Peirce writes to Searle— "is an awful warning against doing so." -/- . (shrink)

In this commentary on Nuno Venturinha’s Description of Situations, after highlighting what in my view are the most significant and innovative features of his work, I focus on Venturinha’s infallibilist approach to knowledge. This topic allows for a wider discussion concerning the pragmatist aspects of the later Wittgenstein’s philosophy. I discuss this in three steps: first, by describing the general similarity between Wittgenstein and the pragmatists with respect to the emphasis on contexts; second, by focusing on the kind of (...) class='Hi'>fallibilism endorsed by the pragmatists and its compatibility with Charles S. Peirce’s concept of the “indubitables,” which I take as a precursor of Wittgenstein’s concept of hinges; and, finally, by advancing the hypothesis that it is possible to find a form of fallibilism in the later Wittgenstein too, notwithstanding his insistence on the impossibility of mistakes. My conclusion is that while Venturinha’s contextualism finds support in the later Wittgenstein’s writings, his infallibilism does not. (shrink)

Impurism says that practical factors encroach on knowledge. An important version of impurism is called ‘Threshold-Impurism,’ which says that practical factors encroach on the threshold that rational credence must pass in order for one to have knowledge. A prominent kind of argument for Threshold-Impurism is the so-called ‘principle-based argument,’ which relies on a principle of fallibilism and a knowledge-action principle. This paper offers a new challenge against Threshold-Impur- ism. I attempt to show that the two principles Threshold-Impurists are committed (...) to—KJ and Fallibilism—are jointly in tension with a widely-held principle of credence that’s called ‘Truth-Directedness,’ in the sense that the former two principles cannot both apply to those who know the third. This tension constitutes a serious challenge to Threshold-Impurists, because it leaves them two options, both of which are undesirable: denying Truth-Directedness, or accepting Truth-Directedness and accepting that whether KJ and Fallibilism apply to a person depends on whether she knows Truth-Directedness.

The paper takes as its starting point the observation that people can be led to retract knowledge claims when presented with previously ignored error possibilities, but offers a noncontextualist explanation of the data. Fallibilist epistemologies are committed to the existence of two kinds of Kp -falsifying contingencies: (i) Non-Ignorable contingencies [NI-contingencies] and (ii) Properly-Ignorable contingencies [PI-contingencies]. For S to know that p, S must be in an epistemic position to rule out all NI-contingencies, but she need not be able to (...) rule out the PI-contingencies. What is required vis-à-vis PI-contingencies is that they all be false . In mentioning PI-contingencies, an interlocutor can lead S mistakenly to think that these contingencies are NI-contingencies, when in fact they are not. Since S cannot rule out these newly mentioned contingencies and since she mistakenly takes them to be NI-contingencies , it is quite natural that she retract her earlier knowledge claim. In short, mentioning NI-contingencies creates a distortion effect. It makes S think that the standards for knowledge are higher than they actually are, which in turn explains why she mistakenly thinks she lacks knowledge. Conclusion: The primary linguistic data offered in support of contextualism can be explained without resorting to contextualism. (shrink)

In classical American pragmatism, fallibilism refers to the conception of truth as an ongoing process of improving human knowledge that is nevertheless susceptible to error. This paper traces appearances of fallibilism in Jewish thought in general, and particularly in the halakhic thought of Eliezer Berkovits. Berkovits recognizes the human condition’s persistent mutability, which he sees as characterizing the ongoing effort to interpret and apply halakhah in shifting historical and social contexts as Torat Ḥayyim. In the conclusion of the (...) article, broader questions and observations are raised regarding Jewish tradition, fallibility, and modernity, and the interaction between Judaism and pragmatism in the history of ideas.

The Contingency Postulate of Truth. - Is there a statement that cannot be false under any contingent conditions? Two well-known philosophical schools have given contradictory answers to this question about the existence of a necessarily true statement: Fallibilists (Albert, Keuth) have denied its existence, transcendental pragmatists (Apel, Kuhlmann) and objective idealists (Wandschneider, Hösle) have affirmed it. Dieter Wandschneider has (following Vittorio Hösle) translated the principle of fallibilism, according to which every statement is fallible, into a thesis which he calls (...) the contingency postulate of truth (CPT). It says: <For every true statement there are contingent conditions.> If this postulate were true, it would mark an insurmountable boundary of knowledge: a final epistemic justification would then not be possible. Wandschneider has therefore developed a counterargument to show that the contingency postulate of truth cannot be formulated without contradiction and implies the thesis that there is at least one necessarily true statement. This essay deals with the systematic question whether the contingency postulate of truth really cannot be presented without contradiction. To this end I will first present the contingency postulate and the associated problems (I.). Then I will analyze Wandschneider's argument against the consistency of the contingency postulate (II.) and finally reject it with the help of some considerations from the field of epistemic logic (III.).

Forms of justification. On the structure and scope of self-refutation arguments in Plato, Cicero and Apel. - In this essay, the structure and scope of transcendental types of argumentation are analyzed, compared and criticized on the basis of the reception of two antiskeptical types of reasoning in ancient philosophy (Plato, Parmenides 135b-c; Cicero, Lucullus § 28) by a contemporary philosophical author (Karl-Otto Apel). Plato puts forward a transcendental argument for the inevitability of a final knowledge. Cicero argues that a principle (...) of fallibilism occurring with universal claim contradicts itself. In Karl-Otto Apel's transcendental pragmatic variant of philosophy, the two types of self-refutation arguments developed in Plato's and Cicero's dialogues are brought together into a single argumentation.

In this paper, we provide a Bayesian analysis of the well-known surprise exam paradox. Central to our analysis is a probabilistic account of what it means for the student to accept the teacher's announcement that he will receive a surprise exam. According to this account, the student can be said to have accepted the teacher's announcement provided he adopts a subjective probability distribution relative to which he expects to receive the exam on a day on which he expects not to (...) receive it. We show that as long as expectation is not equated with subjective certainty there will be contexts in which it is possible for the student to accept the teacher's announcement, in this sense. In addition, we show how a Bayesian modeling of the scenario can yield plausible explanations of the following three intuitive claims: (1) the teacher's announcement becomes easier to accept the more days there are in class; (2) a strict interpretation of the teacher's announcement does not provide the student with any categorical information as to the date of the exam; and (3) the teacher's announcement contains less information about the date of the exam the more days there are in class. To conclude, we show how the surprise exam paradox can be seen as one among the larger class of paradoxes of doxastic fallibilism, foremost among which is the paradox of the preface. (shrink)

In this paper, I defend an epistemic requirement on fitting hopes and worries: it is fitting to hope or to worry that p only if one’s epistemic position makes it rational to suspend judgment as to whether p. This view, unlike prominent alternatives, is ecumenical; it retains its plausibility against a variety of different background views of epistemology. It also has other important theoretical virtues: it is illuminating, elegant, and extensionally adequate. Fallibilists about knowledge have special reason to be friendly (...) to my view; it can help them explain why it can be unfitting to hold on to hope and worry in the face of overwhelming evidence, and it can also help them explain the sense in which knowledge that p and hope that –p are in tension with one another.

From the early-1950s on, F.A. Hayek was concerned with the development of a methodology of sciences that study systems of complex phenomena. Hayek argued that the knowledge that can be acquired about such systems is, in virtue of their complexity (and the comparatively narrow boundaries of human cognitive faculties), relatively limited. The paper aims to elucidate the implications of Hayek’s methodology with respect to the specific dimensions along which the scientist’s knowledge of some complex phenomena may be limited. Hayek’s (...) class='Hi'>fallibilism was an essential (if not always explicit) aspect of his arguments against the defenders of both socialism ([1935] 1948, [1940] 1948) and countercyclical monetary policy ([1975] 1978); yet, despite the fact that his conceptions of both complex phenomena and the methodology appropriate to their investigation imply that ignorance might beset the scientist in multiple respects, he never explicated all of these consequences. The specificity of a scientific prediction depends on the extent of the scientist’s knowledge concerning the phenomena under investigation. The paper offers an account of the considerations that determine the extent to which a theory’s implications prohibit the occurrence of particular events in the relevant domain. This theory of “predictive degree” both expresses and – as the phenomena of scientific prediction are themselves complex in Hayek’s sense – exemplifies the intuition that the specificity of a scientific prediction depends on the relevant knowledge available.

This paper explores two related issues concerning Locke’s account of epistemic justification for empirical knowledge. One issue concerns the degree of justification needed for empirical knowledge. Commentators almost universally take Locke to hold a fallibilist account of justification, whereas I argue that Locke accepts infallibilism. A second issue concerns the nature of justification. Many (though not all) commentators take Locke to have a thoroughly internalist conception of justification for empirical knowledge, whereas I argue that he has a (partly) externalist conception (...) of justification: it is the fact that sensation is caused by an external object that justifies our belief in the corresponding object. So, while most commentators take Locke to be a fallibilist with an internalist conception of justification for empirical knowledge, I argue he is actually an infallibilist with an externalist conception of justification.

‘Post-truth’ has become a buzzword for numerous current crises: the fragmentation of the media landscape, the ongoing debate about ‘fake news’, the loss of trust in science, etc. Although these crises take place in society, it is claimed that the roots of post-truth can be traced back to the history of philosophy. Occasionally, it is asserted that Karl Popper’s critical rationalism gave rise to post-truth: His rejection of verificationism has limited truth claims in the realm of science. Given the absence (...) of infallible evidence and certainty, critical rationalism calls for challenging scientific authority. I argue that post-truth is compatible with critical rationalism from an epistemological point of view, considering that both positions are critical of certainty. However, in critical rationalism, fallibilism, responsibility, and the idea of criticism are combined, and in this respect, it offers a possible way to overcome the problems that are associated with post-truth. This treatment of the problems of post-truth results from the recognition of moral responsibility to take action on the basis of a hypothesis that remains open to revision. (shrink)

The paper introduces a new problem for fallibilist and infallibilist epistemologies – the diachronic threshold problem. As the name suggests, this is a problem similar to the well–known threshold problem for fallibilism. The new problem affects both fallibilism and infallibilism, however. The paper argues that anyone who worries about the well known problem for fallibilism should also worry about this new, diachronic version of the problem.

In this paper we provide a defence of cosmopolitanism from a liberal perspective, examining its moral underpinnings, including moral obligations predicated on a belief in common humanity and the fundamental dignity of human people, cultural capacities that include an embrace of pluralism and a fallibilist disposition, and pragmatist resolve in finding humanitarian solutions to real problems that people face. We also scrutinise the ideal of cosmopolitanism by considering the ‘deeply religious’ as the sort of people about whom it may be (...) said that irreconcilable tensions exist between certain types of commitment and/or belonging and what the demands of cosmopolitanism involve.

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

ENGLISH: The author investigates whether the model prevalent today of an “humble reason” - based on fallibilism and epistemic humility - is the most appropriate to express the theological truth, even in the light of the debate within the contemporary theism (rational theology). To answer this question it is necessary to examine the epistemological status of “human truth” and the “truth of faith”, in order to develop a common approach to sciences, philosophy and theology. Finally, the author shows how (...) the communitarian dimension and the “choice” (a call for freedom) are inherent to theology understood as “critical faith”, whose peculiarity is to posit itself without nostalgia in the middle between fideism, rationalism and a certain relativism. From the path, finally, it emerges the proposal of a new “cristeologia”. ITALIAN: Il rapporto tra fede e ragione è la questione meta-teologica per eccellenza. L’autore si propone dunque d’indagare se il modello oggi prevalente di “ragione umile” – basato su fallibilismo e umiltà epistemica – sia il più adeguato per esprimere le verità teologiche, anche alla luce del dibattito interno al teismo contemporaneo (teologia razionale). Per rispondere a questa domanda è necessario esaminare lo statuto epistemologico della verità umana e della verità di fede, per poter elaborare un metodo comune alle discipline scientifiche, filosofiche e teologiche, capace di trovare un equilibrio tra fideismo e positivismo teologico. Dopo una breve panoramica storica dei rapporti tra fede e ragione nel pensiero occidentale (con particolare attenzione alla dottrina dei praeambula fidei), l’articolo cercherà di mostrare come, nel paradigma della verità relazionale e del fallibilismo sia necessario integrare il problema delle fonti, dell’autorità, del concetto di ispirazione e della nozione di “rivelazione”, giacché contraddistinguono la teologia rispetto alla filosofia. Si mostrerà infine come la dimensione comunitaria e della scelta (appello alla libertà) siano connaturate alla teologia intesa come fede critica, la cui peculiarità è di collocarsi senza nostalgie nel mezzo tra fideismo, razionalismo e un certo relativismo. Dal percorso emergerà infine la proposta di una nuova "cristeologia". (shrink)

In Fallibilism: Evidence and Knowledge, Jessica Brown identifies a number of problems for the so-called knowledge view of justification. According to this view, we cannot justifiably believe what we do not know. Most epistemologists reject this view on the grounds that false beliefs can be justified if, say, supported by the evidence or produced by reliable processes. We think this is a mistake and that many epistemologists are classifying beliefs as justified because they have properties that indicate that something (...) should be excused. Brown thinks that previous attempts to make this case have been unsuccessful. While the difficulties Brown points to are genuine, I think they show that attempts to explain a classificatory judgment haven't been successful. Still, I would argue that the classification is correct. We need a better explanation of this classificatory judgment. I will try to clarify the justification-excuse distinction and explain why it's a mistake to insist that beliefs that violate epistemic norms might be justified. Just as it's possible for a rational agent to act without justification in spite of her best intentions, it's possible that a rational thinker who follows the evidence and meets our expectations might nevertheless believe without sufficient justification. If our justified beliefs are supposed to guide us in deciding what to do, we probably should draw on discussions from morality and the law about the justification/excuse distinction to inform our understanding of the epistemic case.

There is virtually universal agreement in the scientific community that religion does not meet the requirements of science and that its contents can consequently be largely ignored. Yet what exactly is wrong with religion from a scientific point of view and why is religion still so widely spread around the globe? -/- This article, which is strongly influenced by Harris 2005, identifies three items - widespread ignorance of the empirical (2.1), rational (2.2), and fallibilist attitude (2.3) - as religion's primary (...) epistemological or methodological faults. It is then attempted to show that philosophy and science, due to adhering to this "Holy Trinity of Science," do an equal or much better job than religion at satisfying five deep-seated and knowledge-related human needs - the meaning of life (3.1), the origin of morals and ethics (3.2), stopping the infinite regress (3.3), comfort and security (3.4), spirituality (3.5) - for whose satisfaction many people still (incorrectly) turn to religion. The article concludes with an attempt to reconcile science and religion by adopting a decidedly nonphysicalist position, by making a near death experience based case for the natural immortality of the soul/consciousness, and by generally putting spirituality on a scientific and epistemologically sound footing.

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

According to the fallibilist, it is possible for us to know things when our evidence doesn't entail that our beliefs are correct. Even if there is some chance that we're mistaken about p, we might still know that p is true. Fallibilists will tell you that an important virtue of their view is that infallibilism leads to skepticism. In this paper, we'll see that fallibilist impurism has considerable skeptical consequences of its own. We've missed this because we've focused our attention (...) on the high-stakes cases that they discuss in trying to motivate their impurism about knowledge. We'll see this once we think about the fallibilist impurist's treatment of low-stakes cases. (shrink)

The study analyzes Mises‘s approach to the question of apriorism in a broader methodological context. It shows that it is not inevitable to advocate the aprioristic character of economics (resp. science of human action), as Mises does, to maintain the subjectivist-individualist methodology and the effort to adequately grasp the general laws of human action from its perspective. The present redefinition of apriorism is developed on the basis of thoughts of Barry Smith and Alfred Schutz. It suggests abandoning the apodictic character (...) of apriori (which is untenable) and move closer to a broadly defined empiricism. The methodological insights developed in the paper are finally used to contribute to the debate between the behavioral economists and the proponents of rational choice theory. (shrink)

Infallibilism leads to skepticism, and fallibilism is plagued by the threshold problem. Within this narrative, the pragmatic turn in epistemology has been marketed as a way for fallibilists to address the threshold problem. In contrast, pragmatic versions of infallibilism have been left unexplored. However, I propose that going pragmatic offers the infallibilist a way to address its main problem, the skeptical problem. Pragmatic infallibilism, however, is committed to a shifty view of epistemic certainty, where the strength of a subject’s (...) epistemic state can vary depending upon the practical context. Pragmatic views of epistemic strength are quite radical so the argumentative goal of my discussion is to argue for its plausibility, thereby arguing for the plausibility of pragmatic infallibilism. To do so, I discuss the role that the framing of decision problems and the construction of our deliberative attitudes have in our theories of rational choice. And I explore a way in which these necessary components of a normative theory of rationality can be used to motivate pragmatic views of evidential support. Finally, since the plausibility of our pragmatic account will depend upon the plausibility of a constructive account of rational choice, I conclude by comparing the adequacy of the constructive account with orthodox Bayesian and knowledge-based accounts.

The paper begins by reviewing two problems for fallibilism: the lottery problem, or the problem of explaining why fallible evidence, though otherwise excellent, is not enough to know that one will lose the lottery, and Gettier problems. It is then argued that both problems can be resolved if we note an important illocutionary force of knowledge attributions: namely, that when we attribute knowledge to someone we mean to give the person credit for getting things right. Alternatively, to say that (...) a person knows is to say that she got things right due to her own abilities, efforts and actions, rather than due to dumb luck, or blind chance, or something else.

This paper is a companion piece to my earlier paper “Fallibilism and Concessive Knowledge Attributions”. There are two intuitive charges against fallibilism. One is that it countenances the truth (and presumably acceptability) of utterances of sentences such as “I know that Bush is a Republican, though it might be that he is not a Republican”. The second is that it countenances the truth (and presumably acceptability) of utterances of sentences such as “I know that Bush is a Republican, (...) even though I’m not certain that he is”, or “I know that Bush it a Republican, even though it isn’t certain that he is.” In “Fallibilism and Concessive Knowledge Attributions”, I argue that fallibilism in epistemology does not countenance the truth of utterances of sentences such as “I know that Bush is a Republican, though it might be that he is not a Republican”. In this paper, I argue that there are independent reasons for thinking that utterances of sentences such as “I know that Bush is a Republican, though I’m not certain that he is” and “I know that Bush is a Republican, though it’s not certain that he is” are unassertible. More specifically, I argue that these are simply instances of Moore’s Paradox, such as “Dogs bark, but I don’t know that they do.” The right account of Moore’s Paradox does not involve the falsehood of the semantic content of the relevant utterances, but rather their pragmatic unacceptability. So the anti-fallibilist intuitions turn out to have pragmatic, rather than semantic import, and therefore do not tell against the truth of fallibilism. Fallibilism in epistemology is often thought to be theoretically desirable, but intuitively problematic. My purpose with these two papers is to show that fallibilism is not intuitively problematic.

This article argues that, suitably modified, the method of reflective equilibrium is a plausible way of selecting moral principles. The appropriate conception of the method is wide and radical, admitting consideration of a full range of moral principles and arguments, and requiring the enquiring individual to consider others' views and undergo experiences that may offset any formative biases. The individual is not bound by his initial considered judgments, and may revise his view in any way whatsoever. It is appropriate to (...) describe the method as a balance between coherentism and fallibilist foundationalism. With these points in mind, various criticisms, including the claims that considered judgments are not initially credible and are shaped by prejudice, and that the method itself fails to determine principle selection, are challenged.

Anthony Brueckner argues for a strong connection between the closure and the underdetermination argument for scepticism. Moreover, he claims that both arguments rest on infallibilism: In order to motivate the premises of the arguments, the sceptic has to refer to an infallibility principle. If this were true, fallibilists would be right in not taking the problems posed by these sceptical arguments seriously. As many epistemologists are sympathetic to fallibilism, this would be a very interesting result. However, in this paper (...) I will argue that Brueckner’s claims are wrong: The closure and the underdetermination argument are not as closely related as he assumes and neither rests on infallibilism. Thus even a fallibilist should take these arguments to raise serious problems that must be dealt with somehow. (shrink)

Suppose for reductio that I know a proposition of the form <p and I don’t know p>. Then by the factivity of knowledge and the distribution of knowledge over conjunction, I both know and do not know p ; which is impossible. Propositions of the form <p and I don’t know p> are therefore unknowable. Their particular kind of unknowability has been widely discussed and applied to such issues as the realism debate. It hasn’t been much applied to theories of (...) the nature of knowledge. That is what I’m going to do here. (shrink)

William Whewell’s philosophy of science is often overlooked as a relic of 19th century Whiggism. I argue however that his view – suitably modified – can contribute to contemporary philosophy of science, particularly to debates around scientific progress. The reason Whewell’s view needs modification is that he makes the following problematic claim: as science progresses, it reveals necessarily truths and thereby grants a glimpse of the mind of God. Modifying Whewell’s view will involve reinventing his notion of necessary truth as (...) the pragmatist notion of superassertibility. And, if scientific progress does not uncover necessary truths, then it does not reveal the mind of God. The result is an outline of an account of scientific progress that is piecemeal and fallibilist in nature, yet at the same time maintains key Whewellian themes of consilience and the unity of science.

I advance a novel argument for an infallibilist theory of knowledge, according to which we know all and only those propositions that are certain for us. I argue that this theory lets us reconcile major extant theories of knowledge, in the following sense: for any of these theories, if we require that its central condition (evidential support, reliability, safety, etc.) obtains to a maximal degree, we get a theory of knowledge extensionally equivalent to infallibilism. As such, the infallibilist can affirm (...) that, when their conditions are suitably interpreted, most post-Gettier theories of knowledge offer necessary and sufficient conditions for knowledge. The infallibilist can thus reconcile major theories of knowledge, and is in a better position to explain the intuitive appeal of these theories than the fallibilist who only accepts one of them, and rejects the rest.

Anti-exceptionalism about logic is the doctrine that logic does not require its own epistemology, for its methods are continuous with those of science. Although most recently urged by Williamson, the idea goes back at least to Lakatos, who wanted to adapt Popper's falsicationism and extend it not only to mathematics but to logic as well. But one needs to be careful here to distinguish the empirical from the a posteriori. Lakatos coined the term 'quasi-empirical' `for the counterinstances to putative mathematical (...) and logical theses. Mathematics and logic may both be a posteriori, but it does not follow that they are empirical. Indeed, as Williamson has demonstrated, what counts as empirical knowledge, and the role of experience in acquiring knowledge, are both unclear. Moreover, knowledge, even of necessary truths, is fallible. Nonetheless, logical consequence holds in virtue of the meaning of the logical terms, just as consequence in general holds in virtue of the meanings of the concepts involved; and so logic is both analytic and necessary. In this respect, it is exceptional. But its methodologyand its epistemology are the same as those of mathematics and science in being fallibilist, and counterexamples to seemingly analytic truths are as likely as those in any scientic endeavour. What is needed is a new account of the evidential basis of knowledge, one which is, perhaps surprisingly, found in Aristotle. (shrink)

Keith DeRose and Stewart Cohen object to the fallibilist strand of pragmatic invariantism regarding knowledge ascriptions that it is committed to non-cancelable pragmatic implications. I show that this objection points us to an asymmetry about which aspects of the conveyed content of knowledge ascriptions can be canceled: we can cancel those aspects that ascribe a lesser epistemic standing to the subject but not those that ascribe a better or perfect epistemic standing. This situation supports the infallibilist strand of pragmatic invariantism (...) according to which knowledge semantically requires absolute certainty but this claim is often pragmatically weakened: it turns out that exactly those aspects of the conveyed content are cancelable that this view claims are pragmatic. I also argue that attributor contextualism and relativism do not have an alternative explanation of this phenomenon. (shrink)

The tripartite account of propositional, fallibilist knowledge that p as justified true belief can become adequate only if it can solve the Gettier Problem. However, the latter can be solved only if the problem of a successful coordination of the resources (at least truth and justification) necessary and sufficient to deliver propositional, fallibilist knowledge that p can be solved. In this paper, the coordination problem is proved to be insolvable by showing that it is equivalent to the ''''coordinated attack'''' problem, (...) which is demonstrably insolvable in epistemic logic. It follows that the tripartite account is not merely inadequate as it stands, as proved by Gettier-type counterexamples, but demonstrably irreparable in principle, so that efforts to improve it can never succeed.
