The epistemic regress problem targets our ability to provide reasons for our beliefs. If we need reasons for our beliefs, then we may also need to provide reasons for those reasons, and so on into regress. Because the epistemic regress problem is often cast as an attack on our ability to achieve justification, it is often thought that epistemic positions which do not rely on notions like justification escape without difficulty. The first (...) goal of this dissertation is to establish the generality of the epistemic regress problem, beyond all technicalities regarding the nature of justification. To do this, I propose a new minimal epistemic standard, that we should hold no bald assertions to be epistemically acceptable. I then use this epistemic standard to construct two new forms of the epistemic regress problem. The first version of the problem is reminiscent of the classical problem in that it attacks our ability to locate any such reason. The second version of the problem attacks our ability to unite any such reason to a particular claim that it is supposed to support. The second goal of this dissertation is to argue that pragmatism fails as a solution to the epistemic regress problem. The pragmatist seeks to avoid the regress by provisionally accepting their beliefs to be evaluated later. In so doing, the pragmatist seeks to have reasonable beliefs, but only after having accepted them provisionally. After eliminating other theoretical alternatives that the pragmatist may use to bolster their position, I argue that the pragmatic solution is not successful because (1) it is committed to some foundational beliefs that are necessary to facilitate the evaluation of their provisional beliefs which fall prey to the regress, and (2) the employment of these criteria of evaluation encounters the regress in its second form. I conclude by advocating for an understanding of Pyrrhonian skepticism under which we are not required to eschew our everyday beliefs that is nevertheless commensurate with the epistemic regress.

I give an interpretation according to which Meno’s paradox is an epistemic regress problem. The paradox is an argument for skepticism assuming that (1) acquired knowledge about an object X requires prior knowledge about what X is and (2) any knowledge must be acquired. (1) is a principle about having reasons for knowledge and about the epistemic priority of knowledge about what X is. (1) and (2) jointly imply a regress-generating principle which implies that knowledge (...) always requires an infinite sequence of known reasons. Plato’s response to the problem is to accept (1) but reject (2): some knowledge is innate. He argues from this to the conclusion that the soul is immortal. This argument can be understood as a response to an Eleatic problem about the possibility of coming into being that turns on a regress-generating causal principle analogous to the regress-generating principle presupposed by Meno’s paradox.

Andrew Cling presents a new version of the epistemic regress problem, and argues that intuitionist foundationalism, social contextualism, holistic coherentism, and infinitism fail to solve it. Cling’s discussion is quite instructive, and deserving of careful consideration. But, I argue, Cling’s discussion is not in all respects decisive. I argue that Cling’s dilemma argument against holistic coherentism fails.

Since the resurgence of infinitism in contemporary epistemology, Peter Klein has been consistent in providing arguments against the three other possible solutions (i.e., foundationalism, coherentism, skepticism) to the Regress Problem, which in turn is a key aspect of the justification condition for the traditional account of knowledge as justified true belief. Klein’s successful effort in reviving the often-dismissed solution and further advancing it as the sole solution to the Regress Problem cannot be ignored as he finds (...) it necessary to not only raise problems for the viability of the three contenders but, more so, definitively invalidate them as equally possible solutions. This paper responds to Klein’s objection to foundationalism, the crucial reasons for which he offers in several of his works concerning infinitism and the Regress Problem: i) that foundationalism inevitably leads either to arbitrariness or to the continuation of the regress of reasons; ii) that a proposition continuously enhanced by reasons has more epistemic warrant than a proposition supported by a chain of reasons which ends at basic beliefs, and; iii) that basic beliefs are not tantamount to fully justified beliefs. For each, certain problems can be raised by employing foundationalist arguments in order to arrive at the conclusion that in spite of his astute reasoning, Klein’s objection is insufficient to rule out foundationalism as a possible solution to the Regress Problem.

The Problem of Epistemic Regress in Contemporary Epistemology and The Adequacy of Improved Solution Suggestions One of the main problems of epistemology; whether our beliefs about the world are correct or not, that is to say, it’s the problem of whether we have suitable reasons or not to think that we have the enough knowledge. The value of our beliefs and its epistemic justifiability are being examined through this problem. In this respect, Undoubtedly; one (...) of the greatest problem of contemporary epistemology is the problem of epistemic regress that is a problem of justification. On the other hand the solution suggestions developed for this problem, which is shown as a threat factor for the knowledge in point, don’t seem sufficient. In this article, the problem of epistemic regress which is emerging in the contemporary period will be discussed by examining the perspectives of tradition and contemporary epistemology. Four different and similar basic approaches that arise resulting from the problem of regress solution proposals brought by foundationalism, compatibilism, externalism and internalism will be analyzed.

Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.

This chapter has two goals: to motivate the foundationalist solution to the regress problem and to defend it against arguments from Sellars, BonJour and Klein. Both the motivation and the defence of foundationalism raise larger questions about the relationship between foundationalism and access internalism. I argue that foundationalism is not in conflict with access internalism, despite influential arguments to the contrary, and that access internalism in fact supplies a theoretical motivation for foundationalism. I conclude that foundationalism and access (...) internalism form a coherent and well-motivated package. (shrink)

A novel solution is offered for how emotional experiences can function as sources of immediate prima facie justification for evaluative beliefs, and in such a way that suffices to halt a justificatory regress. Key to this solution is the recognition of two distinct kinds of emotional skill (what I call generative emotional skill and doxastic emotional skill) and how these must be working in tandem when emotional experience plays such a justificatory role. The paper has two main parts, the (...) first negative and the second positive. The negative part criticises the epistemic credentials of Epistemic Perceptualism (e.g., Tappolet 2012, 2016; Doring 2003, 2007; Elgin 2008; Roberts 2003), the view that emotional experience alone suffices to prima facie justify evaluative beliefs in a way that is analogous to how perceptual experience justifies our beliefs about the external world. The second part of the paper develops an account of emotional skill and uses this account to frame a revisionary form of Epistemic Perceptualism that succeeds where the traditional views could not. I conclude by considering some objections and replies. (shrink)

Utilitarian (U.) theories must be capable of being applied in practical reasoning, or they would have no value as a guide to rational conduct. However, I show that epistemic extensions to U. theories produce logical confusion. Basic questions about what one needs to know in order to apply a U. analysis embroil one in an infinite regress. And attempts to incrementally apply U. either are no help at all (leaving one entirely 'in the dark'), or in general constitute (...) arbitrary gambles which no practical reasoner could defend taking. These problems are serious enough to completely discredit U. theories as having any relevance to practical reasoning. (shrink)

Klein’s account of epistemic justification, infinitism, supplies a novel solution to the regress problem. We argue that concentrating on the normative aspect of justification exposes a number of unpalatable consequences for infinitism, all of which warrant rejecting the position. As an intermediary step, we develop a stronger version of the ‘finite minds’ objection.

This paper critically evaluates the regress argument for infinitism. The dialectic is essentially this. Peter Klein argues that only an infinitist can, without being dogmatic, enhance the credibility of a questioned non-evident proposition. In response, I demonstrate that a foundationalist can do this equally well. Furthermore, I explain how foundationalism can provide for infinite chains of justification. I conclude that the regress argument for infinitism should not convince us.

Em seguida, apresentaremos uma importante (...) distinção que é útil para um melhor entendimento da nossa tese, isto é, a distinção entre justificação proposicional e doxástica. Então, abordaremos as visões tradicionais que supostamente alegam resolver este problema, mostrando que todas são problemáticas. Por fim, apresentaremos a visão que pretendemos defender, mostrando como ela pode oferecer uma resposta ao problema do regresso epistêmico, de uma maneira que as outras visões não podem.

Abstract: In this paper we present a version of a theory that we will call Epistemic Contextualism - the view that the context and the standards that it determines, play a central role in evaluating whether, or not, a subject has justification, and therefore knowledge - to try to solve one of the most influential problems in epistemology, namely, the Epistemic Regress Problem. The first step will be to characterize the epistemic regress problem. Next, we present an important distinction that is useful to a better understanding of our view, that is, the distinction between propositional and doxastic justification. Then, we present traditional views that allegedly claim to solve this problem showing that all are problematic. The final step concerns the exposition of the view we want to defend, showing how it can solve the epistemic regress problem in a way that the other views cannot. Keywords: Epistemic Regress, Justification, Knowledge, Epistemic Contextualism. (shrink)

I argue against the skeptical epistemological view exemplified by the Groarkes that “all theories of informal argument must face the regress problem.” It is true that in our theoretical representations of reasoning, infinite regresses of self-justification regularly and inadvertently arise with respect to each of the RSA criteria for argument cogency (the premises are to be relevant, sufficient, and acceptable). But they arise needlessly, by confusing an RSA criterion with argument content, usually premise material.

It is commonly assumed that blameworthiness is epistemically constrained. If one lacks sufficient epistemic access to the fact that some action harms another, then one cannot be blamed for harming. Acceptance of an epistemic condition for blameworthiness can give rise to a worry, however: could agents ever successfully evade blameworthiness by deliberately stunting their epistemic position? I discuss a particularly worrisome version of such epistemic shirking, in which agents pre-emptively seek to avoid access to potentially morally (...) relevant facts. As Roy Sorensen and Jan Willem Wieland have argued, we seem to be faced with a potentially troubling regress when trying to explain what goes wrong in such situations. I argue that the solution to this so-called Shirker Problem is not to be found in complicated and demanding anti-shirking-principles with universal scope and potentially self-reflexive content. Instead, careful consideration of the necessary motivational make-up of genuine shirkers reveals their ignorance to lack the necessary depth to be exculpatory. Since shirkers by definition react to the possibility of the revelation of morally relevant facts with acts of epistemic self-limitation, they necessarily prove guilty of a form of culpable moral recklessness. Epistemic shirking thus does not pose a worrisome problem for ethical theory. (shrink)

Most epistemologists agree that epistemic justification is required for knowledge. This requirement is usually formulated in one of two ways: S knows that p only if S is justified in believing that p. S knows that p only if S's belief that p is justified. Surprisingly and are generally regarded as synonymous formulations of the justification condition. In Chapter 1, I argue that such a synonymy thesis is mistaken and that, in fact, and specify substantively different requirements. requires that (...) the person be justified, whereas requires that the belief in question be justified, and intuitively, these constitute different requirements. Thus, it is concluded that and employ inherently different kinds of epistemic justification in their respective analysantia. I dub them "personal justification" and "doxastic justification", respectively. The remainder of the dissertation is devoted to demonstrating both the legitimacy and the importance of the personal/doxastic justification distinction. For example, the distinction helps account for the divergent intuitions that regularly arise regarding justificatory evaluations in demon-world contexts. ;In Chapters 2 and 3 I provide analyses for doxastic and personal justification. Chapter 2 spells out an externalist reliabilist account of doxastic justification which safely avoids demon-world counterexamples. Chapter 3 advances an internalist coherence account of personal justification. In defending this coherence theory, I argue that all foundation theories are false and that the regress argument on which they are predicated is unsound. ;In Chapter 4, I propose an analysis of ordinary knowledge which only requires doxastic justification. Nevertheless personal justification plays a negative, undermining role in the analysis. I then demonstrate that this analysis of knowledge is immune to typical Gettier examples. It also remains unscathed by Harman's beefed-up Gettier cases. Finally, I consider a stronger analysis of knowledge requiring both doxastic and personal justification. Though the latter analysis proves too strong for ordinary knowledge, it remains interesting as an analysis of a more intellectualistic kind of knowledge. ;The final chapter examines the internalist/externalist controversy and demonstrates that this controversy is yet another manifestation of the personal/doxastic justification conflation.

In der Dialektik der Kritk der reinen Vernunft entwickelt Kant eine Position, welche auf verschiedene Probleme anwendbar ist, bei denen die Vollständigkeit zu erfüllender Bedingungen wesentlicher Aspekt des Problems ist. Diese Position soll durch die hier angestellte Übertragung auf das systematische Problem der inferentiellen Rechtfertigung so klar wie möglich herausgearbeitet werden. Durch die Übertragung wird das Regressproblem und damit auch das Problem der Rechtfertigung in seiner gegenwärtigen Form aufgelöst.

Title in English: : A Contextualist Answer to Agrippa's Argument.

The foundationalist needs to deal with two fundamental problems: (i) to explain how a justificator grants justification without itself need justification and (ii) to determine the justificator’s epistemic status. Burdzinski (Burdzinski 2007), following Sellars and Bonjour, argues that the perceptive experience could not be a response to the first problem, because if its content was not propositional it would not grant justification and if its content was propositional it would grant justification and would require justification. My proposal is (...) that perceptual experience justifies in virtue of its representational nature. The act of taking the content of a perception by its face value is justified until there is a reason to the contrary, ie, this act is prima facie justified. This forces us to answer the second problem by saying that the basic justificator is not infallible. This falibilist response dislike the skeptic, but it is the best foundationalist answer to epistemic regress. (shrink)

This paper presents a uniform general account of regress problems in the form of a pentalemma—i.e., a set of five mutually inconsistent claims. Specific regress problems can be analyzed as instances of such a general schema, and this Regress Pentalemma Schema can be employed to generate deductively valid arguments from the truth of a subset of four claims to the falsity of the fifth. Thus, a uniform account of the nature of regress problems allows for an (...) improved understanding of specific regress objections or arguments, and, correspondingly, of the general logical geography of the debate about infinite regresses. This uniform approach is illustrated by a treatment of the classical epistemological problem of justification, but it encompasses a whole variety of cases including explanation and ontological grounding. Furthermore, this general account is compared and contrasted with the existing literature discussing argument schemata for regress objections, particularly with the work of Jan Willem Wieland. It is shown how such other schemata can be incorporated and superseded by the general Regress Pentalemma Schema. (shrink)

This Open Access book addresses the age-old problem of infinite regresses in epistemology. How can we ever come to know something if knowing requires having good reasons, and reasons can only be good if they are backed by good reasons in turn? The problem has puzzled philosophers ever since antiquity, giving rise to what is often called Agrippa's Trilemma. The current volume approaches the old problem in a provocative and thoroughly contemporary way. Taking seriously the idea that (...) good reasons are typically probabilistic in character, it develops and defends a new solution that challenges venerable philosophical intuitions and explains why they were mistakenly held. Key to the new solution is the phenomenon of fading foundations, according to which distant reasons are less important than those that are nearby. The phenomenon takes the sting out of Agrippa's Trilemma; moreover, since the theory that describes it is general and abstract, it is readily applicable outside epistemology, notably to debates on infinite regresses in metaphysics.

In this essay, I assess Keith Lehrer's case against Foundationalism, which consists of variations on three objections: The Independent Information or Belief Objection, The Risk of Error Objection, and the Hidden Argument Objection. I conclude that each objection fails for reasons that can be endorsed – indeed, I would say for reasons that should be endorsed – by antifoundationalists and foundationalists alike.

This paper evaluates Peter Klein’s objection to foundationalism. According to Klein, foundationalism fails because it allows arbitrariness “at the base.” I first explain that this objection can be interpreted in two ways: either as targeting dialectical foundationalism or as targeting epistemic foundationalism. I then clarify Klein’s concept of arbitrariness. An assertion or belief is assumed to be arbitrary if and only if it lacks a reason that is “objectively and subjectively available.” Drawing on this notion, I evaluate Klein’s objection. (...) I first argue that his objection construed as targeting dialectical foundationalism fails, since nothing prevents dialectical foundationalism from ruling out arbitrary assertions. I then argue that the objection seen as targeting epistemic foundationalism cannot be disqualified in the way some foundationalists believe. However, I show that also the objection so construed does not succeed, since epistemic foundationalism need not countenance arbitrary beliefs. (shrink)

This paper examines the Stoic account of apprehension (κατάληψις) (a cognitive achievement similar to how we typically view knowledge). Following a seminal article by Michael Frede (1983), it is widely thought that the Stoics maintained a purely externalist causal account of apprehension wherein one may apprehend only if one stands in an appropriate causal relation to the object apprehended. An important but unanswered challenge to this view has been offered by David Sedley (2002) who offers reasons to suppose that the (...) Stoics (or at least Zeno, the founder of the Stoa) did not make such a causal stipulation. I offer a defence of the traditional, causal reading against the challenges raised by Sedley but also argue, against the traditional view, that the Stoic account incorporated an internalist element. On the hybrid account defended here, in order to apprehend not only must the agent stand in an appropriate causal relation to the object apprehended but the agent’s appearance of the object must also be clear (a feature which is accessible to the epistemic agent). The traditional scholarly view rejects internalist interpretations because it is thought that such interpretations cannot make sense of the Stoics’ discussion of the ‘automatic assent’ produced by kataleptic appearances and a purely externalist view is taken to be charitable insofar as it saves the Stoics from a vicious regress which they would otherwise face (were they internalists). I spell out how the regress might be taken to function and defend an internalist interpretation against both these charges. The internalist element embraced by the Stoics does not lead to the problems it is often thought to and the account defended here not only does justice to the textual evidence but also sheds light on the Stoic debates with their sceptical opponents and grants the Stoics an epistemic account fit for purpose.

In this paper, we shall describe and critically evaluate four contemporary theories which attempt to solve the problem of the infinite regress of reasons: BonJour's ‘impure’ coherentism, BonJour's foundationalism, Haack's ‘foundherentism’ and Dancy's pure coherentism. These theories are initially put forward as theories about the justification of our empirical beliefs; however, in fact they also attempt to provide a successful response to the question of their own ‘metajustification.’ Yet, it will be argued that 1) none of the examined (...) theories is successful as a theory of justification of our empirical beliefs, and that 2) they also fall short of being adequate theories of metajustification. It will be further suggested that the failure of these views on justification is not coincidental, but is actually a consequence of deeper and tacitly held problematic epistemological assumptions (namely, the requirements of justificatory generality and epistemic priority), whose acceptance paves the way towards a generalized scepticism about empirical justification.

A theory of truth is introduced for a first--order language L of set theory. Fully interpreted metalanguages which contain their truth predicates are constructed for L. The presented theory is free from infinite regress, whence it provides a proper framework to study the regress problem. Only ZF set theory, concepts definable in L and classical two-valued logic are used.

Fading Foundations: Probability and the Regress Problem. By Atkinson David, Peijnenburg Jeanne.

In this paper a class of languages which are formal enough for mathematical reasoning is introduced. Its languages are called mathematically agreeable. Languages containing a given MA language L, and being sublanguages of L augmented by a monadic predicate, are constructed. A mathematical theory of truth (shortly MTT) is formulated for some of those languages. MTT makes them fully interpreted MA languages which posses their own truth predicates. MTT is shown to conform well with the eight norms formulated for theories (...) of truth in the paper 'What Theories of Truth Should be Like (but Cannot be)', by Hannes Leitgeb. MTT is also free from infinite regress, providing a proper framework to study the regress problem. Main tools used in proofs are Zermelo-Fraenkel (ZF) set theory and classical logic. (shrink)

Recent work by Peijnenburg, Atkinson, and Herzberg suggests that infinitists who accept a probabilistic construal of justification can overcome significant challenges to their position by attending to mathematical treatments of infinite probabilistic regresses. In this essay, it is argued that care must be taken when assessing the significance of these formal results. Though valuable lessons can be drawn from these mathematical exercises (many of which are not disputed here), the essay argues that it is entirely unclear that the form of (...) infinitism that results meets a basic requirement: namely, providing an account of infinite chains of propositions qua reasons made available to agents.

I will explore the paradoxical nature of epistemic access. By critiquing the traditional conception of mental states that are labelled as ’knowledge’, I demonstrate the susceptibility of these states to an infinite regress, thus, challenging their existence and validity. I scrutinise the assumption that an epistemic agent can have complete epistemic access to all facts about a given object while simultaneously being ignorant of certain truths that impact the very knowledge claims about the object. I further (...) analyse the implications of this paradox when attempting to fine-grain the parameters of epistemic access, which happens to reveal the vacuity of such definitions and the inevitability of the regress.

The New Evil Demon Problem presents a serious challenge to externalist theories of epistemic justification. In recent years, externalists have developed a number of strategies for responding to the problem. A popular line of response involves distinguishing between a belief’s being epistemically justified and a subject’s being epistemically blameless for holding it. The apparently problematic intuitions the New Evil Demon Problem elicits, proponents of this response claim, track the fact that the deceived subject is epistemically blameless (...) for believing as she does, not that she is justified for so believing. This general strategy—which I call the “unjustified-but-blameless maneuver”—is motivated, in part, by the assumption that the distinction between epistemic justification and blamelessness is merely an extension of the familiar distinction between moral justification and blamelessness. In this paper, I consider three ways of drawing the distinction between justification and blamelessness familiar from the moral domain: the first in terms of a connection with reactive attitudes, the second in terms of the distinction between wrongness and wronging, and the third in terms of reasons-responsiveness. All three ways of drawing the distinction, I argue, make it difficult to see how an analogous distinction in the epistemic domain could help externalists explain away the intuitions which underwrite the New Evil Demon Problem. Motivating the unjustified-but-blameless maneuver, I conclude, is a much less straightforward task than its proponents tend to assume. (shrink)

The subject of this article is Modal-Epistemic Arithmetic (MEA), a theory introduced by Horsten to interpret Epistemic Arithmetic (EA), which in turn was introduced by Shapiro to interpret Heyting Arithmetic. I will show how to interpret MEA in EA such that one can prove that the interpretation of EA is MEA is faithful. Moreover, I will show that one can get rid of a particular Platonist assumption. Then I will discuss models for MEA in light of the problems (...) of logical omniscience and logical competence. Awareness models, impossible worlds models and syntactical models have been introduced to deal with the first problem. Certain conditions on the accessibility relations are needed to deal with the second problem. I go on to argue that those models are subject to the problem of quantifying in, for which I will provide a solution. (shrink)

This paper explores the relationship between scepticism and epistemic relativism in the context of recent history and philosophy of science. More specifically, it seeks to show that significant treatments of epistemic relativism by influential figures in the history and philosophy of science draw upon the Pyrrhonian problem of the criterion. The paper begins with a presentation of the problem of the criterion as it occurs in the work of Sextus Empiricus. It is then shown that significant (...) treatments of epistemic relativism in recent history and philosophy of science (critical rationalism, historical philosophy of science and the strong programme) draw upon the problem of the criterion. It is briefly suggested that a particularist response to the problem of the criterion may be put to good use against epistemic relativism. (shrink)

Many of us are unmoved when it is objected that some morally or intellectually suspect source agrees with our belief. While we may tend to find this kind of guilt by epistemic association unproblematic, I argue that this tendency is a mistake. We sometimes face what I call the problem of unwelcome epistemic company. This is the problem of encountering agreement about the content of your belief from a source whose faults give you reason to worry (...) about the belief's truth, normative status, etiology, or implications. On the basis of an array of cases, I elaborate four distinct kinds of problems that unwelcome epistemic company poses. Two of these are distinctly epistemic, and two are moral. I canvass possible responses, ranging from stubbornness to an epistemic prudishness that avoids unwelcome company at all costs. Finally, I offer preliminary lessons of the problem and distinguish it from the problem of peer disagreement. (shrink)

Simple regression (regression analysis with a single explanatory variable), and multiple regression (regression models with multiple explanatory variables), typically correspond to very different biological questions. The former use regression lines to describe univariate associations. The latter describe the partial, or direct, effects of multiple variables, conditioned on one another. We suspect that the superficial similarity of simple and multiple regression leads to confusion in their interpretation. A clear understanding of these methods is essential, as they underlie a large range of (...) procedures in common use in biology. Beyond simple and multiple regression in their most basic forms, understanding the key principles of these procedures is critical to understanding, and properly applying, many methods, such as mixed models, generalised models, and causal inference using graphs (including path analysis and its extensions). A simple, but careful, look at the distinction between these two analyses is valuable in its own right, and can also be used to clarify widely-held misconceptions about collinearity (correlations among explanatory variables). There is no general sense in which collinearity is a problem. We suspect that the perception of collinearity as a hindrance to analysis stems from misconceptions about interpretation of multiple regression models, and so we pursue discussions about these misconceptions in this light. In particular, collinearity causes multiple regression coefficients to be less precisely estimated than corresponding simple regression coefficients. This should not be interpreted as a problem, as it is perfectly natural that direct effects should be harder to characterise than univariate associations. Purported solutions to the perceived problems of collinearity are detrimental to most biological analyses. (shrink)

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the (...) pre-Gettier tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

Standard objections to the notion of a hedged, or ceteris paribus, law of nature usually boil down to the claim that such laws would be either 1) irredeemably vague, 2) untestable, 3) vacuous, 4) false, or a combination thereof. Using epidemiological studies in nutrition science as an example, I show that this is not true of the hedged law-like generalizations derived from data models used to interpret large and varied sets of empirical observations. Although it may be ‘in principle impossible’ (...) to construct models that explicitly identify all potential causal interferers with the relevant generalization, the view that our failure to do so is fatal to the very notion of a cp-law is plausible only if one illicitly infers metaphysical impossibility from epistemic impossibility. I close with the suggestion that a model-theoretic approach to cp-laws poses a problem for recent attempts to formulate a Mill-Ramsey-Lewis theory of cp-laws. (shrink)

According to standard scientific realism, science seeks truth and we can justifiably believe that our successful theories achieve, or at least approximate, that goal. In this paper, I discuss the implications of the following competitor thesis: Any theory we may favor has competitors such that we cannot justifiably deny that they are approximately true. After defending that thesis, I articulate three specific threats it poses for standard scientific realism; one is epistemic, the other two are axiological (that is, pertaining (...) to the claim that science seeks truth). I also flag an additional axiological “challenge,” that of how one might justify the pursuit of a primary aim, such as truth. Bracketing epistemic realism, I argue that the axiological threats can be addressed by embracing a refined realist axiological hypothesis, one that specifies a specific subclass of true claims sought in science. And after identifying three potential responses to the axiological “challenge,” I contend that, while standard axiological realism appears to lack the resources required to utilize any of the responses, the refined realist axiology I embrace is well suited to each.

In this chapter, I produce counterexamples to Presuppositional Epistemic Contextualism (PEC), a view about the semantics of ‘knowledge’-ascriptions that I have argued for elsewhere. According to PEC, the semantic content of the predicate ‘know’ at a context C is partly determined by the speakers’ pragmatic presuppositions at C. The problem for the view that I shall be concerned with here arises from the fact that pragmatic presuppositions are sometimes known to be true by the speakers who make them: (...) hence the Problem of Known Presuppositions. After discussing several unsuccessful ways to solve the problem, I propose the addition of a new Lewisian rule of proper ignoring to the semantics of PEC--namely, the Rule of Evidence-Based Ignoring. If the proposed account succeeds, the Problem of Known Presuppositions has a straightforward solution within the framework of PEC. (shrink)

Recently, there has been growing concern that increased partisanship in news sources, as well as new ways in which people acquire information, has led to a proliferation of epistemic bubbles and echo chambers: in the former, one tends to acquire information from a limited range of sources, ones that generally support the kinds of beliefs that one already has, while the latter function in the same way, but possess the additional characteristic that certain beliefs are actively reinforced. Here I (...) argue, first, that we should conceive of epistemic bubbles and echo chambers as types of epistemically pernicious groups, and second, that while analyses of such groups have typically focused on relationships between individual members, at least part of what such groups epistemically pernicious pertains to the way that members rely on the groups themselves as sources of information. I argue that member reliance on groups results in groups being attributed a degree of credibility that outruns their warrant, a process I call groupstrapping. I argue that by recognizing the groupstrapping as an illicit method of forming and updating beliefs we can make progress on some of the open questions concerning epistemically pernicious groups.

Intractable political disagreements threaten to fracture the common ground upon which we can build a political community. The deepening divisions in society are partly fueled by the ways social media has shaped political engagement. Social media allows us to sort ourselves into increasingly likeminded groups, consume information from different sources, and end up in polarized and insular echo chambers. To solve this, many argue for various ways of cultivating more responsible epistemic agency. This chapter argues that this epistemic (...) lens does not reveal the complete picture and therefore misses a form of moral respect required to reestablish cooperation across disagreements in a divided society. The breakdown of discourse online provides renewed reasons to draw out not an epistemic but a moral basis for political cooperation among diverse citizens—one inspired by Rawlsian political liberalism. We need ways to cultivate mutual respect for our fellow citizens in order to reestablish common moral ground for political debate. (shrink)

When a proposition might be the case, for all an agent knows, we can say that the proposition is epistemically possible for the agent. In the standard possible worlds framework, we analyze modal claims using quantification over possible worlds. It is natural to expect that something similar can be done for modal claims involving epistemic possibility. The main aim of this paper is to investigate the prospects of constructing a space of worlds—epistemic space—that allows us to model what (...) is epistemically possible for ordinary, non-ideally rational agents like you and me. I will argue that the prospects look dim for successfully constructing such a space. In turn, this will make a case for the claim that we cannot use the standard possible worlds framework to model what is epistemically possible for ordinary agents. (shrink)

In this paper I introduce some of the key elements of Daniel Dennett’s theory of intentional attribution and their relation with his notion of rationality. While doing so I will show that Dennett’s approach implies a circularity in the process of attribution of rationality, and that his resource to evolutionary arguments for trying to avoid an infinite regress does not help him to avoid the problem. My presentation will include a revision of Dennett’s arguments for epistemic intentional (...) ascription and rationality attribution as well as some criticisms developed against his proposal. At the end of the article I will extend the criticisms and present my view about his proposal for ideal rationality attribution. (shrink)

This paper proposes a view on epistemic relativism that arises from the problem of the criterion, keeping in consideration that the assessment of criterion standards always occurs in a certain context. The main idea is that the epistemic value of the assertion “S knows that p” depends not only on the criterion adopted within an epistemic framework and the relationship between said criterion and a meta-criterion, but also from the collaboration with other subjects who share the (...) same standards. Thus, one can choose between particularist and methodist criteria according to the context of assessment. This position has the advantage of presenting a new perspective concerning both the criterion problem and the problem of inter-contextuality in the evaluation of different epistemic frameworks.

Political polarization is one of the most discussed challenges facing contemporary democracies and is often associated with a broader epistemic crisis. While inspiring a large literature in political science, polarization’s epistemic problems also have significance for normative democratic theory, and this study develops a new approach aimed at understanding them. In contrast to prominent accounts from political psychology—group polarization theory and cultural cognition theory—which argue that polarization leads individuals to form unreliable political beliefs, this study focuses on system-level (...) diversity. It argues that polarization’s epistemic harms are best located in its tendency to reduce the diversity of perspectives utilized in a democratic system and in how this weakens the system’s ability to identify and address problems of public concern. Understanding such harms is also argued to require a greater consideration of the political dynamics of polarization and issues of elite discourse, alongside political psychology. (shrink)

Many philosophers have adopted epistemic expressivism in recent years. The core commitment of epistemic expressivism is that epistemic claims express conative states. This paper assesses the plausibility of this commitment. First, we raise a new type of problem for epistemic expressivism, the epistemic motivation problem. The problem arises because epistemic expressivists must provide an account of the motivational force of epistemic judgment (the mental state expressed by an epistemic claim), (...) yet various features of our mental economy seem to show that they can’t do so. Second, we develop what we take to be the most promising response to that problem for expressivists. We end by noting that this response faces an important challenge pertaining to the psychology of epistemic criticism and praise. (shrink)

The problem of infinite regress presents a profound challenge in epistemology and philosophy, questioning the possibility of achieving foundational knowledge amidst an endless chain of justifications. This paper introduces a set of four axioms designed to directly address and resolve the problem of infinite regress, ensuring theoretical rigor and applicability across diverse scenarios, including simulated or illusory realities. By focusing on Direct Address, Intellectual Rigor in All Realities, Avoiding Pragmatic Dismissals, and Theoretical Consistency, these axioms provide (...) a structured framework for evaluating philosophical theories aimed at overcoming this complex issue. The paper explores current theories that align with these axioms, evaluates popular theories that do not, and argues for the critical role of these axioms in guiding future philosophical inquiry and resolution of infinite regress.

How should you decide what to do when you’re uncertain about basic normative principles? A natural suggestion is to follow some "second-order:" norm: e.g., obey the most probable norm or maximize expected choiceworthiness. But what if you’re uncertain about second-order norms too—must you then invoke some third-order norm? If so, any norm-guided response to normative uncertainty appears doomed to a vicious regress. This paper aims to rescue second-order norms from the threat of regress. I first elaborate and defend (...) the claim some philosophers have made that the regress problem forces us to accept normative externalism, the view that at least one norm is incumbent on all agents regardless of their normative beliefs. But, I then argue, we need not accept externalism about first-order norms, thus closing off any question of how agents should respond to normative uncertainty. Rather, we can head off the threat of regress by ascribing external force to a single second-order norm: the enkratic principle. (shrink)

Addressing the ‘virtue conflation’ problem requires the preservation of intuitive distinctions between virtue types, that is, between intellectual and moral virtues. According to one influential attempt to avoid this problem proposed by Julia Driver, moral virtues produce benefits to others—in particular, they promote the well-being of others—while the intellectual virtues, as such, produce epistemic good for the agent. We show that Driver's demarcation of intellectual virtue, by adverting to the self-/other distinction, leads to a reductio, and ultimately, (...) that the prospects for resolving the virtue conflation problem look dim within an epistemic consequentialist approach to the epistemic right and the epistemic good.
