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 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.

Philosophical reflection on scientific laws often struggles to distinguish between "mere" accidental regularities and "genuine" laws. This paper argues that the felt necessity attributed to certain scientific generalizations is not an empirical discovery of "physical necessity," but a result of definitive semantic entailment. By introducing a distinction between Descriptive (DS) and Definitive (DF) truth-characters—the foundational architecture of Nomic Anti-Monism (NA-M)—I diagnose "lawlikeness" as a category error termed "possibling": the projection of semantic closure onto empirical inquiry. Using the direct foil of (...) Salmon’s (1989) modal desiderata to illustrate this error, I apply a Gödelian constraint (1931) to the substitution of external necessity for internal inconceivability. I conclude that Popperian fallibilism constitutes a vital "modal hygiene" required to prevent scientific explanation from collapsing into dogmatic derivation. (shrink)

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)

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)

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)

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)

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)

In a recent article in this journal, Stump argues that pragmatism distances itself from absolutism due to its assent to fallibilism while it rejects relativism at the same time because of its insistence on experience. Therefore, pragmatism can provide a third position between relativism and absolutism. I argue in this note that his argument is profoundly inadequate for both claims. Fallibilism is compatible with both relativism and absolutism, and accordingly cannot be considered as the middle ground. Furthermore, the (...) experience itself and the way it is inferred from is the subject of the relativists’ debates, not a response. (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)

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)

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)

This paper challenges the perceived tension between moral objectivity and systematic uncertainty, arguing that the two are mutually reinforcing. By distinguishing between methodological objectivity (universal standards of logical consistency and evidence-responsiveness) and inferential objectivity (context-specific ethical conclusions), I demonstrate how moral discourse can maintain rigorous standards while navigating the complexities of historical and cultural variation. -/- The argument begins with a critique of G.E. Moore’s Principia Ethica and W.D. Ross’s intuitionism, noting that, while they correctly defend objectivity, their reliance on (...) "epistemic immediacy" leaves them ill-equipped to address persistent disagreement and practical complexity. Drawing on Isaiah Berlin’s value pluralism and contemporary decision theory, I propose a Tripartite Uncertainty Framework that distinguishes among three dimensions of ethical struggle: epistemic uncertainty regarding gaps in empirical knowledge; practical uncertainty concerning the 'moral weight' of competing duties; and ontological uncertainty arising from the inherent incommensurability of values. This framework provides a systematic foundation for Methodological Fallibilism, a disciplined approach to ethical reasoning that acknowledges the limits of knowledge without abandoning the commitment to objective truth. This technical grounding offers a vital diagnostic tool for assessing the "moral remainder" in political agency, particularly in cases where uncertainty is deployed as a strategic rationalization for silence.

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.

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.

I defend nine elements of pragmatic philosophy and show how they apply to scientific inquiry. Pragmatism provides a focus on inquiry that adopts fallibilism, denies all foundations, and looks for practical or concrete effects of our theories and actions. Pragmatists hold that universal and fixed principles are not necessary for objective knowledge, maintaining an everyday realism while rejecting metaphysical realism and the dualism that it entails. In the empirical sciences we must interact with things in the world to see (...) whether or not our theories are correct, therefore recovering a pragmatic notion of experience from James and Dewey is central to understanding physical science. Pragmatists also deny the existence of simple dichotomies, arguing instead that opposing concepts lie along a continuum. Notably, facts and values are both objects of unified inquiry. Finally, I consider the pragmatists’ various theories of truth and argue that it would be be er to avoid defining truth by adopting a deflationary account. Rather than taking the definition of truth to be central to pragmatism, I argue that should be left aside given that classical pragmatists disagree about it. Classical pragmatists could then be said to agree on a basic set of principles while leaving truth undefined. Philosophers of science should follow the common core of principles that define pragmatic philosophy as they try to understand scientific practice; indeed, these teachings of pragmatism have already been accepted widely by philosophers of science.

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.

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)

To cope with the complexity of the world, cognitively limited agents must employ framing to identify what is relevant and stabilise meaning. Yet democracy rests on the Popperian fallibilist imperative to break existing frames. Hence Hamlet’s problem: while fallibilism yields great epistemic benefits and grounds egalitarian ethos, the frame-breaking it invites leads to paralysis and distrust. Technocracy and populism can be then read as political responses to an essentially cognitive problem. A political environment capable of containing Hamlet’s problem must (...) be self-organising and self-complexifying, to process dispersed knowledge inclusively, reconcile citizens to the tensions democracies generate, and secure public justification.

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)

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 method of reflective equilibrium (MRE) is a method of justification popularized by John Rawls and further developed by Norman Daniels, Michael DePaul, Folke Tersman, and Catherine Z. Elgin, among others. The basic idea is that epistemic agents have justified beliefs if they have succeeded in forming their beliefs into a harmonious system of beliefs which they reflectively judge to be the most plausible. Despite the common reference to MRE as a method, its mechanisms or rules are typically expressed in (...) a metaphorical or simplified manner and are therefore criticized as too vague. Recent efforts to counter this criticism have been directed towards the attempt to provide formal explications of MRE. This paper aims to supplement these efforts by providing an informal working definition of MRE. This approach challenges the view that MRE can adequately be characterized only in the negative as a set of anti-essentialisms. I argue that epistemic agents follow MRE iff they follow four interconnected rules, which are concerned with a minimalistic form of foundationalism, a minimalistic form of fallibilism, a moderate form of holism, and a minimalistic form of rationality. In the critical spirit of MRE, the corresponding working definition is, of course, provisional and revisable. In general, the aim is to contribute to a reflective equilibrium (RE) concerning MRE. If it is successful, this working definition provides a better grasp of the most basic elements of the method and thereby enhances our understanding of it. (shrink)

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)

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: 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.

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)

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)

‘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.

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.

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 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.

The Cohesive Tetrad is a framework of truth governance that is methodologically sound, philosophically accountable, and rooted in ethical necessity. This framework responds to the crisis of reductionism in the data era by restoring human dignity as the axis of science, policy, and the interior life. Four “languages” of truth are recognized as mutually binding domains. Sabda (Revelatory Word, The Word, the authoritative) restores telos and ethical boundaries so that science does not fall into technique without horizon. Logic maintains the (...) coherence of definitions, premises, and consequences so that normative intent and experiential measures do not collapse under contradiction or structural bias. Qualia brings living evidence back into decision spaces through security, trust, and social cohesion that can be designed, measured, and audited. Mistika calibrates intention and moral steadfastness so that costly right decisions can be sustained and moral licensing is prevented. All four are verified in akhlak as the surface of public testing that becomes visible over time, such that claims must correspond to behavioral traces and their impact on the most vulnerable. This framework is supported by philosophy, teleology, deontology, phenomenology, hermeneutics, and pragmatism, integrated through a spirit of fallibilism and iterative correction. To ensure replicability, concise audit artifacts are provided, including the Values and Boundaries Document, Decision Script, Human Impact Test, Intention Calibration Document, and Ethical Premortem. The Cohesive Tetrad also mitigates the Goodhart problem by placing indicators of akhlak as stable cross-checks for technical indicators. Its simple sequence of operation, namely purpose, form, human, intention, and fruit, yields decisions that are more just, honest, and humane, and shifts the center of gravity of truth from rhetoric to the tested fruits of action.

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: if a belief can be at once warranted and false, then the Gettier Problem cannot be solved; if a belief can be at once warranted and false, then its warrant can be transferred (...) to an accidentally true belief; 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)

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)

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.

How to think a unique and determinative turn in analytic philosophy of mind? To answer this question this article first presents an attempt to render clear that analytic phenomenology, by contrast with conceptions of phenomenology of the XXth century, beneficially dispenses with several methodological and conceptual assumptions that were assumed to be compulsory, as phenomenological reduction, a notion of synthesis, and a philosophical notion of the a priori. It then presents some eventual difficulties to the achievement of a phenomenological turn (...) within analytic philosophy, which are, the neglect of historicity, abstractionism, the acknowledgement of the place of language in our lives, and solipsism. It finally presents several demands that concern the felicity of contemporary analytic phenomenologies, namely, anti-abstractionism, fallibilism, attention to polyadic relations, and the integration of ecological and decolonial concerns of our cultures.

This conceptual meta-synthesis explores the intersections between mathematical literacy and the philosophy of mathematics education, revealing how these two fields mutually enrich the theoretical and practical dimensions of mathematics teaching and learning. Mathematical literacy, traditionally understood as the ability to use mathematics for solving real-world problems, has evolved into a multidimensional construct encompassing reasoning, communication, reflection, and ethical awareness. Meanwhile, the philosophy of mathematics education interrogates the epistemological, ontological, and axiological foundations of mathematics, emphasizing its nature as a human and (...) cultural practice rather than a static system of truths. By integrating philosophical perspectives—particularly constructivism, fallibilism, and socioepistemology—this study argues for a humanistic reconceptualization of mathematical literacy that values context, culture, and reflection. Through an interpretive synthesis of recent international literature, the study identifies three key domains of convergence: epistemological alignment, cultural-ethical grounding, and reflective technological mediation. It concludes that embedding philosophical inquiry into mathematical literacy enhances not only cognitive competence but also moral and cultural consciousness, positioning mathematics education as a transformative endeavor that empowers learners to interpret and reshape their world through reflective reasoning.

This chapter explores a species of false modesty, false intellectual humility, which is defined as affected or pretended intellectual humility concealing intellectual arrogance. False intellectual humility is situated in a virtue epistemological framework, where it is contrasted with intellectual humility, understood as excellence in self-attribution of intellectual weakness. False intellectual humility characteristically takes the form of insincere expressions of ignorance or uncertainty – as when dogmatically committed conspiracy theorists insist that they just want to know what’s going on – and, (...) in such cases, false intellectual humility is a kind of false skepticism or false fallibilism. In connection with this, the chapter further explores the relationship between the concepts of intellectual humility, skepticism, and fallibilism. A distinction can be drawn between the virtues of intellectual humility, skepticism, and fallibilism, but the traditional association of skepticism and fallibilism with intellectual humility is vindicated by the fact that the virtues of intellectual humility, skepticism, and fallibilism overlap.

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-Impurism. 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.

That we may rely on our knowledge seems like a platitude. Yet, the view that knowledge is sufficient for permissible reliance faces a major challenge: when much hangs on whether we know, relying on our knowledge seems to license irrational action. Unfortunately, extant proposals to meet this challenge (Hawthorne & Stanley, 2008; Williamson, 2005a; Schulz, 2017, 2021b) either fail to make the correct predictions about high-stakes cases or, as I will argue, face a substantial objection. In this paper, I will (...) offer two novel proposals for defending the sufficiency of knowledge for permissible reliance. My favoured proposal, which I call Flexible Fallibilism, is based on the idea that stakes can affect how we rely on our knowledge and how our knowledge determines what is rational for us to do. Besides making the correct predictions about high-stakes cases, I will argue that Flexible Fallibilism also provides us with a knowledge-based account of when to simplify our practical reasoning. Afterwards, I will present another proposal, which I call Dual Infallibilism, that combines two recent claims by Moss (2013, 2018) and Jackson (2019a) about credal knowledge and the metaphysics of doxastic states. While the offered proposals share various virtues, I will argue that we ultimately should prefer Flexible Fallibilism. (shrink)

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)

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.

Although certain recent developments in mendacious political manipulation of public discourse are horrifying to the academic mind, I argue that we should not panic. Charles Peirce’s pragmatist epistemology with its teleological arc, long horizon, and rare balance between robust realism and contrite fallibilism offers guidance to weather the storm, and perhaps even see it as inevitable in our intellectual development. This paper explores Peirce’s classic “four methods of fixing belief”, which takes us on an entertaining and still very pertinent (...) tour through tenacity, authority and a priori speculation to the method of science – the only method which is both public and self-correcting. Although in the West we (mostly) proudly self-conceive as living in a ‘scientific age’, I argue that this is premature. Precisely insofar as we treat the misbehavior of governments as a harbinger of doom, we remain trapped in authoritarian modes of thinking which Peirce identified with medievalism, although modernity is increasingly quickening around us in worldwide information-sharing practices that are shaped entirely by mutual help. With this framework in mind, many tactics of recent media are most helpfully seen as belonging not to a post-truth, but a pre-truth stage of human intellectual development. Advice on this is sought from Plato, who of course also faced a world that was ‘pre-academic’. (shrink)

We provide a Camusian/Peircean notion of inquiry that emphasises an attitude of fallibilism and sustained epistemic dissonance as a conceptual framework for a theory of classroom practice founded on Deep Reflective Thinking (DTR), in which the cultivation of collective doubt, reflective evaluation and how these relate to the phenomenological aspects of inquiry are central to communities of inquiry. In a study by Fynes-Clinton, preliminary evidence demonstrates that if students engage in DRT, they more frequently experience cognitive dissonance and as (...) a result improve their ability to engage in further and more frequent DRT. Sustained intellectual progress occurs when the inquiry reaches a point whereby students can thoughtfully move between the position of disequilibrium (doubt) and equilibrium (belief) whilst understanding the impermanency of any fixed belief, which, in turn, enables reconstruction of thinking and appropriation of learning in the context of collaborative philosophical inquiry.

In addition to being a founder of American pragmatism, Charles Sanders Peirce was a scientist and an empiricist. A core aspect of his thoroughgoing empiricism was a mindset that treats all attitudes as revisable. His fallibilism seems to require us to constantly seek out new information, and to not be content holding any beliefs uncritically. At the same time, Peirce often states that common sense has an important role to play in both scientific and vital inquiry, and that there (...) cannot be any “direct profit in going behind common sense.” Our question is the following: alongside a scientific mindset and a commitment to the method of inquiry, where does common sense fit in? Peirce does at times directly address common sense; however, those explicit engagements are relatively infrequent. In this paper, we argue that getting a firm grip on the role of common sense in Peirce’s philosophy requires a three-pronged investigation, targeting his treatment of common sense alongside his more numerous remarks on intuition and instinct. By excavating and developing Peirce’s concepts of instinct and intuition, we show that his respect for common sense coheres with his insistence on the methodological superiority of inquiry. We conclude that Peirce shows us the way to a distinctive epistemic position balancing fallibilism and anti-scepticism, a pragmatist common sense position of considerable interest for contemporary epistemology given current interest in the relation of intuition and reason.

“I know that p but it is possible that not-p” sounds contradictory. Some philosophers, notably David Lewis, have taken this as evidence that knowledge requires infallibility. Others have attempted to undermine that inference by arguing that there is a plausible pragmatic explanation of why such sentences sound odd, and thus do not undermine fallibilism. I argue that the proffered pragmatic explanations fail and I raise challenges for any possible pragmatic explanation of the character of concessive knowledge attributions. It is (...) reasonable to conclude that concessive knowledge attributions are genuine contradictions. (shrink)

This paper focuses on what Peirce means by scepticism, with particular reference to the anticartesian nature of his philosophy and the question of whether Peirce constantly shows a univocal and consistent attitude towards all types of scepticism. It argues that Peirce can be described as an antisceptic, and then goes on to discuss the extent to which Peirce’s fallibilism can claim to succeed in entirely divorcing itself from a sceptical outlook. -/- .
