According to infinitism, all justification comes from an infinite series of reasons. Peter Klein defends infinitism as the correct solution to the regress problem by rejecting two alternative solutions: foundationalism and coherentism. I focus on Klein's argument against foundationalism, which relies on the premise that there is no justification without meta-justification. This premise is incompatible with dogmatic foundationalism as defended by Michael Huemer and Time Pryor. It does not, however, conflict with non-dogmatic foundationalism. Whereas dogmatic foundationalism (...) rejects the need for any form of meta-justification, non-dogmatic foundationalism merely rejects Laurence BonJour's claim that meta-justification must come from beliefs. Unlike its dogmatic counterpart, non-dogmatic foundationalism can allow for basic beliefs to receive meta-justification from non-doxastic sources such as experiences and memories. Construed thus, non-dogmatic foundationalism is compatible with Klein's principle that there is no justification without meta-justification. I conclude that Klein's rejection of foundationalism. fails. Nevertheless, I agree with Klein that when in response to a skeptical challenge we engage in the activity of defending our beliefs, the number of reasons we can give is at least in principle infinite. I argue that this type of infinity is benign because, when we continue to give reasons, we will eventually merely repeat previously stated reasons. Consequently, I reject Klein's claim that the more reasons we give the more we increase the justification of our beliefs. (shrink)

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.

Primarily using philosophy, but also some social science, Escape from Leviathan (EfL) explains and defends what it calls an extreme version of the implicit ‘classical liberal compatibility thesis’: liberty, welfare, and anarchy are overwhelmingly complementary in normal practice (rationality is added for its intimate theoretical connections to these categories). This is done using theories, not definitions, of each concept. This important thesis is entirely positive. Therefore, somewhat unusually, all normative issues are avoided as irrelevant distractions in this context. In addition, (...) the epistemology used is also unorthodox. A justificationist, or foundationalist, approach would be literally illogical: the self-refuting trilemma faced by ‘supporting justifications’ (as regards arguments and evidence) is of entailing infinite regresses, dogmatic starting points, or circularities. Consequently, critical rationalism is assumed: conjecture and criticism are all that is possible. Thus all aspects of the conjectured thesis are explained and defended from criticism as thoroughly as the book can encompass. It is concluded that the thesis has not been refuted and so may be critically preferred. (However, this could all still be viewed as a ‘justification’ by those thus inclined.) All of this is made clear enough in the short introductory chapter and repeated where relevant throughout. Yet some reviews do not have a firm grasp of the specific project and so reject it with unsound criticisms. We now turn to one such example. (shrink)

Defeaters can prevent a perceptual belief from being justified. For example, when you know that red light is shining at the table before you, you would typically not be justified in believing that the table is red. However, can defeaters also destroy a perceptual experience as a source of justification? If the answer is ‘no’, the red light defeater blocks doxastic justification without destroying propositional justification. You have some-things-considered, but not all-things-considered, justification for believing that the table is red. If (...) the answer is ‘yes’, the red light defeater blocks doxastic justification by destroying propositional justification. You have neither all-things-considered nor some-things-considered justification for believing that the table is red. According to dogmatism, the justificational force of perceptual experiences is indestructible. According to conservatism about sense experience, a perceptual experience ceases to have justificational force if there is evidence against its reliability. Finally, according to meta-evidentialism, a perceptual experience is blocked from being a source of justification is there is no evidence of its reliability. I argue that, of these three theories, meta-evidentialism is the most plausible. (shrink)

Foundationalists distinguish basic from nonbasic beliefs. At a first approximation, to say that a belief of a person is basic is to say that it is epistemically justified and it owes its justification to something other than her other beliefs, where “belief” refers to the mental state that goes by that name. To say that a belief of a person is nonbasic is to say that it is epistemically justified and not basic. Two theses constitute Foundationalism: (a) Minimality: There are (...) some basic beliefs, and (b) Exclusivity: If there are any nonbasic beliefs, that is solely because they (ultimately) owe their justification to some basic belief. Proponents of Minimality but not Exclusivity endorse Minimal Foundationalism. Proponents of Exclusivity but not Minimality endorse either Epistemic Nihilism, the view that there are no justified beliefs, or some non-foundationalist epistemology such as Coherentism or Infinitism. In this essay I aim to characterize the notion of a basic belief more precisely and to assess some arguments for and against Foundationalism. In the process, I hope to exhibit the resilience and attractiveness of Foundationalism. (shrink)

Foundationalist, Coherentist, Skeptic etc., have all been united in one respect--all accept epistemic justification cannot result from an unending, and non-repeating, chain of reasons. Peter Klein has recently challenged this minimal consensus with a defense of what he calls "Infinitism"--the position that justification can result from such a regress. Klein provides surprisingly convincing responses to most of the common objections to Infinitism, but I will argue that he fails to address a venerable metaphysical concern about a certain type of regress. (...) My conclusion will be that until Klein answers these metaphysical worries he will not have restored Infinitism as a viable option in epistemology. (shrink)

As the Pyrrhonians made clear, reasons that adequately justify beliefs can have only three possible structures: foundationalism, coherentism, and infinitism. Infinitism—the view that adequate reasons for our beliefs are infinite and non-repeating—has never been developed carefully, much less advocated. In this paper, I will argue that only infinitism can satisfy two intuitively plausible constraints on good reasoning: the avoidance of circular reasoning and the avoidance of arbitrariness. Further, I will argue that infinitism requires serious, but salutary, revisions in our evaluation (...) of the power of reasoning. Thus, reasoning can not provide a basis for assenting to a proposition—where to assent to a proposition, p, means to believe that we know that p. A non-dogmatic form of provisional justification will be sketched. Finally, the best objections to infinitism, including those posed by the Pyrrhonians, will be shown (at least provisionally!) to be inadequate. (shrink)

What follows is a taxonomy of arguments that regresses of inferential justification are vicious. They fall out into four general classes: conceptual arguments from incompleteness, conceptual arguments from arbitrariness, ought-implies-can arguments from human quantitative incapacities, and ought-implies can arguments from human qualitative incapacities. They fail with a developed theory of "infinitism" consistent with valuational pluralism and modest epistemic foundationalism.

In this chapter, the author regards reliabilism as one of the major achievements of twentieth century philosophy and Alvin Goldman as one of the chief architects of this important theory. It focuses on three related issues in Goldman's epistemology. Goldman has recently been making friendly overtures toward evidentialist epistemologies, and although the author agrees that reliabilism needs some kind of evidentialist element. More specifically, the author think he concedes too much to the evidentialist. In particular, he concedes: that a great (...) many beliefs cannot be justified without evidence, in particular, that some beliefs require nondoxastic evidence; that evidential fit can be understood in non‐process‐reliabilist terms, and that the aforementioned or some similar understanding of evidential fit makes sense of propositional, or ex ante, justification. Goldman has never lost sight of the epistemic significance of ways of coming to believe, and he is well aware of the differences between process reliabilism and indicator reliabilism. (shrink)

This article offers a limited defense of metaphysical “infinitism,” the view that there are, or might be, infinite chains of ontological dependence. According to a widespread presupposition, there must be an ultimate ground of being—most likely, a plurality of fundamental atoms. Contrary to this view, this article shows that metaphysical infinitism is internally coherent. In particular, a parallel with the debate concerning infinitism about epistemic justification is suggested, and an “emergence model” of being is put forward. According to the emergence (...) model, the being of any given entity gradually arises out of an infinite series of progressively less dependent entities—it is not wholly transmitted, as it were, from a basic, ungrounded level to all the dependent ones in a step-by-step fashion. Some objections are considered and rebutted. (shrink)

Available from UMI in association with The British Library. Requires signed TDF. ;Belief in God is a belief about a matter of fact and existence . I assume that BG is meaningful, coherent and neither probably true or probably false . ;The evidentialist objection to BG presupposes that we have obligations in respect of those beliefs that we accept, this being a voluntary form of assent to propositions . EO claims that acceptance of BG without sufficient evidence in its (...) support is irrational. But we cannot have evidence for all our beliefs; the need to avoid an infinite regress of justification typically leads EO to endorse some form of foundationalism . This allows certain beliefs to be basic ; EO must defend a criterion of proper basicality which excludes BG from that status. Typically, this restricts properly basic beliefs to those that are either self-evident, evident to the senses or incorrigible . ;Plantinga argues that this criterion is self-referentially incoherent and implausible , and claims that BG can be properly basic. This does not commit him to allowing just any belief to be properly basic, because basic beliefs have justifying conditions which allow him to point to differences between BG and obviously irrational beliefs . Criteria for proper basicality are to be arrived at inductively, from sample-sets of the beliefs we do in fact hold as basic . ;However, this procedure can be used to defend the restriction of proper basicality for matter of fact beliefs to those formed, justified and defeated on the basis of sense-experience, and so allows EO to be maintained . BG cannot be formed directly on the basis of religious experience, for this procedure shows none of the features of reliable, and some of the features of unreliable, epistemic practices . Nor is BG related to our trust in epistemic practices as are our fundamental beliefs about matters of fact . ;'Wittgensteinian basicalism' sees BG as an unjustified and unjustifiable cognitive claim constitutive of the religious language-game and form of life . But a Wittgensteinian epistemology rejects metaphysics as illusion, and grants BG rationality only at the cost of sacrificing its objectivity . Attempts to show that BG is presupposed in the assumption that the universe is intelligible fail because scepticism is not self-refuting; we cannot know that the universe is in fact intelligible . ;BG is not analogous to those beliefs we hold without evidence but which are clearly rational.

Epistemic infinitism is one of the logically possible responses to the epistemic regress problem, claiming that the justification of a given proposition requires an infinite and non-circular structure of reasons. In this paper, I will examine the dialectic between the epistemic infinitist and the regress skeptic, the sort of skeptic that bases his attack to the possibility of justification on the regress of reasons. I aim to show that what makes epistemic infinitism appear as well-equipped to silence the regress skeptic (...) is the very same thing that renders it susceptible to a powerful skeptical assault by the regress skeptic.

Can a belief source confer justification when we lack antecedent justification for believing that it’s reliable? A negative answer quickly leads to skepticism. A positive answer, however, seems to commit one to allowing pernicious reasoning known as “epistemic bootstrapping.” Puzzles surrounding bootstrapping arise because we illicitly assume either that justification requires doxastic awareness of a source’s epistemic credentials or that there is no requirement that a subject be aware of these credentials. We can resolve the puzzle by splitting the horns (...) and requiring a non-conceptual awareness of, or direct acquaintance with, a source’s legitimacy. Requiring non-conceptual as opposed to doxastic awareness halts the regress and avoids the skeptical results. On the other hand, requiring non-conceptual awareness also guarantees that we are aware of evidence for a source’s reliability prior to using that source to form justified beliefs; we thereby avoid the problem of allowing epistemic bootstrapping to generate the illicit gains in justification.

According to externalist reliabilism and dogmatic foundationalism, it's possible to gain knowledge through a perceptual experience without being in a position to know that the experience is reliable. As a result, both of these views face the problem of making knowledge of perceptual reliability too easy, for they permit deducing perceptual reliability from particular perceptual experience without already knowing that these experiences are trustworthy. Ernest Sosa advocates a two-stage solution to the problem. At the first stage, a (...) rich body of perceptual animal knowledge is acquired. At the second stage, perceptual knowledge becomes reflective after deducing perceptual reliability from the initial body of perceptual animal knowledge. I defend the alternative approach of rejecting both externalist reliabilism and dogmatic foundationalism. According to the alternative view, perceptual knowledge and knowledge of perceptual reliability require each other. Such a cognitive structure seems viciously circular. I propose that the appearance of vicious circularity dissipates when the relationship in question is viewed, not as one of temporal priority, but instead as synchronic mutual dependence. At a given time, one cannot have perceptual knowledge without knowledge of perceptual reliability, and vice versa. Such mutual dependence, I argue, is benign. (shrink)

This paper formally explores the common ground between mild versions of epistemological coherentism and infinitism; it proposes—and argues for—a hybrid, coherentist–infinitist account of epistemic justification. First, the epistemological regress argument and its relation to the classical taxonomy regarding epistemic justification—of foundationalism, infinitism and coherentism—is reviewed. We then recall recent results proving that an influential argument against infinite regresses of justification, which alleges their incoherence on account of probabilistic inconsistency, cannot be maintained. Furthermore, we prove that the Principle of Inferential Justification (...) has rather unwelcome consequences—formally resembling the Sorites paradox—as soon as it is iterated and combined with a natural Bayesian perspective on probabilistic inferences. We conclude that strong versions of foundationalism and infinitism should be abandoned. Positively, we provide a rough sketch for a graded formal coherence notion, according to which infinite regresses of epistemic justification will often have more than a minimal degree of coherence.

Em segundo lugar, explico como o infinitista pode oferecer uma solução ao problema do regresso epistêmico. Em terceiro lugar, explico como o infinitismo, per se, é compatível com as teorias daqueles que sustentam 1) que o conhecimento requer certeza e que uma tal forma (...) superior de conhecimento é possível, bem como com as daqueles que rejeitam algum ou ambos os conjuntos em 1). Em outras palavras, o infinitismo nem endossa, nem rejeita o ceticismo, tomando-se essa tese como sendo aquela segundo a qual nós não possuímos conhecimento naquelas situações que nos parecem cognoscíveis. PALAVRAS-CHAVE – Certeza. Coerentismo. Fundacionismo. Infinitismo. Pirronismo. Regresso epistêmico. ABSTRACT The purpose of the paper is to show how robust accounts of justification and certainty can be developed within infinitism. First, I explain how the infinitist conception of epistemic justification differs from both the foundationalist and coherentist conceptions. Second, I explain how the infinitist can provide a solution to the epistemic regress problem. Third, I explain how infinitism, per se, is compatible with both the views of those who hold 1) that knowledge requires certainty and that such high-grade knowledge is possible as well as those who deny either or both conjuncts in 1). In other words, infinitism neither endorses nor rejects skepticism, taking that view to mean that we do not have knowledge in those areas commonly thought to be within our ken. KEY WORDS – Certainty. Coherentism. Foundationalism. Infinitism. Pyrrhonism. Epistemic regress. (shrink)

Infinitism is often presented as a rival to foundationalism and coherentism as available answers to the epistemic regress problem. The most prominent contemporary defense of infinitism, due to Peter Klein, rests on the notion that an agent can perpetually amplify the justification for her belief insofar as they are able to iteratively answer an interlocutor’s questions why the proffered grounds for their belief should count as providing justification for that belief. We show that this argument does not offer any basis (...) for preferring infinitism over foundationalism and coherentism, because those views are able to accommodate the insight that justification for a belief can be continually amplified. Klein’s argument for infinitism thus falls short of its aspirations of proving that infinitism qua rival of foundationalism and coherentism is the most credible solution to the epistemic regress problem.

While C. I. Lewis was traditionally interpreted as an epistemological foundationalist throughout his major works, virtually every recent treatment of Lewis's epistemology dissents. But the traditional interpretation is correct: Lewis believed that apprehensions of "the given" are certain independently of support from, and constitute the ultimate warrant for, objective empirical beliefs. This interpretation proves surprisingly capable of accommodating apparently contrary textual evidence. The non-foundationalist reading, by contrast, simply cannot explain Lewis's explicit opposition to coherentism and his insistence that only (...) apprehensions of the given enable us to answer the regress problem -- and so vindicate the possibility of empirical justification.

The flight from foundationalism in the earlier part of this century left several options in its wake. Distress over the possibility of foundationalist replies to the regress problem, coupled with consternation over the thought of circular reasoning mysteriously becoming acceptable as the circle gets large led to the attraction of holistic theories of a coherentist variety. Yet, such coherentisms seemed to leave the belief system cut off from the world, and perhaps a better idea was to abandon the approach to (...) epistemology that centered on the concepts of evidence and justificatory relations and focus instead on connections between our thoughts and the world which they are about, an idea leading to causal and reliability theories.

This paper is a response to Peter Klein's "Human Knowledge and the Infinite Progress of Reasoning". After briefly discussing what Klein says about the requirement, for doxastic justification, that a belief be formed in the right way, I'll make the following three points: Klein's solution to the regress problem isn't an infinitist solution, Klein's position on doxastic justification faces a troubling dilemma, and Klein's objection to foundationalism fails.

An agent’s belief in a proposition, E0, is justified by an infinite regress of deferred justification just in case the belief that E0 is justified, and the justification for believing E0 proceeds from an infinite sequence of propositions, E0, E1, E2, etc., where, for all n ≥ 0, En+1 serves as the justification for En. In a number of recent articles, Atkinson and Peijnenburg claim to give examples where a belief is justified by an infinite regress of deferred justification. I (...) argue here that there is no reason to regard Atkinson and Peijnenburg’s examples as cases where a belief is so justified. My argument is supported by careful consideration of the grounds upon which relevant beliefs are held within Atkinson and Peijnenburg’s examples. (shrink)

The article discusses infinitism, the view that a belief is justified for a subject only if she possesses an infinite chain of available reasons for that belief. In its most recent and sophisticated version, the view allegedly escapes the problems that trouble its main competitors, foundationalism and coherentism, while avoiding the traditional objections which relegated it to a marginal place. The article argues that despite these improvements, sophisticated versions of infinitism face a pressing problem, viz. they are unable to appropriately (...) articulate propositional and doxastic justification.

As part of\nthe defense he rejects infinitism--the view that holds that\nthe solution to the problem of the regress of justificatory\nreasons is that the reasons are infinitely many and\nnonrepeating. I examine some of those arguments and attempt\nto show that they are not really telling against (at least\nsome versions of) infinitism.

The regress of reasons threatens an epistemic agent’s right to claim that any beliefs are justified. In response, Peter Klein’s infinitism argues that an infinite series of supporting reasons of the right type not only is not vicious but can make for epistemic justification. In order to resist the sceptic, infinitism needs to provide reason to think that there is at least one justified belief in the world. Under an infinitist conception this involves showing that at least one belief is (...) supported by an infinite series of supporting reasons. This paper argues that showing this makes problems for the infinitist. The finite minds problem that prevents completion of an infinite series is well documented. This paper examines alternative attempts to provide evidence of infinity that the infinitist might take, whether by using a notion of justification without infinite reasons or by altering the notion of evidence. It concludes that both of these fail and consequently infinitism is unable to offer a solution to Agrippa’s trilemma. (shrink)

By justification we understand what makes a belief epistemologically viable: generally this is considered knowledge that is true. The problem is defining this with a higher degree of precision because this is where different conflicting conceptions appear. On the one hand, we can understand justification as what makes it reasonable to acquire or maintain a belief; on the other, it is what increases the probability that the belief is true. This work tries to prove that beliefs depend on other beliefs (...) that are epistemically justified and that such beliefs are the result of (i.e., they arise from) our privileged intuition of reality. For this, we examine the concept of epistemic regress. Epistemic reasons authorize a proposition P to be the conclusion of an argument in which such reasons function as premises and are vulnerable to epistemic regress. The three most important approaches to epistemic regress are Infinitism, Coherentism and Foundationalism. (shrink)

In this paper, I will present and defend an argument from the conditional character of inferential justification against the version of epistemic infinitism Klein advances. More specifically, after proposing a distinction between propositional and doxastic infinitism, which is based on a standard distinction between propositional and doxastic justification, I will describe in considerable detail the argument from conditionality, which is mainly an argument against propositional infinitism, and clarify some of its main underlying assumptions. There are various responses to be found (...) in Klein’s works to this argument, and my aim is to show that none of those responses can be plausibly held without infinitism losing its title to being a genuine non-skeptical alternative.

Objectives: Self-compassion functions as a psychological buffer in the face of negative life experiences. Considering that suicidal thoughts and behaviors and non-suicidal self-injury are often accompanied by intense negative feelings about the self, self-compassion may have the potential to alleviate these negative attitudes and feelings toward oneself. This meta-analysis investigated the associations of self-compassion with STBs and NSSI.Methods: A literature search finalized in August 2020 identified 18 eligible studies, including 8,058 participants. Two studies were longitudinal studies, and the remainder (...) were cross-sectional studies. A random-effects meta-analysis was conducted using CMA 3.0. Subgroup analyses, meta-regression, and publication bias analyses were conducted to probe potential sources of heterogeneity.Results: With regard to STBs, a moderate effect size was found for self-compassion. Positively worded subscales exhibited statistically significant effect sizes: self-kindness, common humanity, and mindfulness. For NSSI, a small effect size was found for self-compassion. There was a large heterogeneity, and publication bias was minimal. Subgroup analysis results showed that sample characteristic was a moderator, such that a larger effect size was witnessed in clinical patients than sexually/racially marginalized individuals, college students, and healthy-functioning community adolescents.Conclusions: Self-compassion was negatively associated with STBs and NSSI, and the effect size of self-compassion was larger for STBs than NSSI. More evidence is necessary to gauge a clinically significant protective role that self-compassion may play by soliciting results from future longitudinal studies or intervention studies. (shrink)

Infinitism, along with foundationalism and coherentism, is a logically possible solution to the epistemic regress problem. But unlike the other two views, infinitism has only been developed and defended as a plausible solution since the late 1990’s. Infinitists grant that although there is an ending point of any actual chain of cited reasons for a belief, no belief (including the last one cited) is fully justified until a reason for it is provided. In addition to differing with foundationalism about the (...) existence of so-called basic beliefs, infinitism depicts reasoning as a process through which full doxastic justification is generated, rather than as a device for merely transferring doxastic justification from one belief to another. Thus, like coherentism, infinitism attempts to account for the origin of epistemic doxastic justification without invoking self-justified beliefs whose justification is transmitted through reasoning. But infinitism parts company with coherentism by maintaining (1) that circular reasoning is unable to provide a doxastic justification for any belief and (2) that there is a linear epistemic structure of our beliefs that reflects the fact that some beliefs are epistemically prior to others. (shrink)

There are many things that could be wrong with foundationalism. For example, some have claimed that a so‐called basic belief cannot be both 1) a reason for non‐basic beliefs and 2) such that it cannot be provided with at least prima facie justification.1 If something is a reason, they say, then that something has to be a proposition (or sufficiently proposition‐like) and if it is a proposition (or sufficiently proposition‐like), then it is the kind of thing that requires a reason (...) in order to be even prima facie justified.2 Another reason that some give for rejecting normative foundationalism is that it leads directly to skepticism.3 There is no way, they claim, to move from so‐called basic propositions (typically given as first person introspective reports) to “external world” propositions by employing normatively acceptable principles of reasoning.4 Still others have thought that the invention of a nonrea‐soned reason was as ad hoc as the invention of an unmoved mover.5.

This essay is an introductory overview of the considerations in favor of epistemic infinitism, the view that the demands of justification are that one must have non-terminating series of reasons for one's beliefs if they are to be knowledge.

This paper concerns various competing views on the nature of perceptual justification. Various thought experiments that motivate various views are discussed. Once reliabilism is rejected and some form of internalism is instead embraced, the following issue arises: must an internalist nevertheless require that perceptual justification involve the possession of evidence for the reliability of our perceptual processes? Matthias Steup answers in the affirmative, espousing what he calls internalist reliabilism. Some problems are raised for this form of internalism.

Does the export orientation of a firm affect the likelihood that it adopts an environmental management certification? We use meta-regression methods to analyze systematically the corpus of published research on export-led adoption of the largest and most prominent certification, ISO 14001. We show that the explanatory variables authors choose to include in their models reflect the tenets of stakeholder and institutional theories. We also find that the literature suffers from substantial publication bias but that, once this is accounted for (...) appropriately, a genuine effect remains. The evidence from 20 years of published studies taken as a whole is that export does incentivize the adoption of the standard as often hypothesized by proponents of voluntary approaches and self-regulation.

The paper aims to show how in practice the requirement to maintain the coherence of the system of beliefs and the corresponding behavior of «spontaneous beliefs» within the concept of empirical knowledge by L. Bonjour can be correlated. The main example considered is P. Kosso’s arguments about the reliability of Thucydides’ «History» connected with the idea of possibility of justification restricted to a single source of evidence. As a heuristics we deal with the problem of how to establish (...) the contextual dependence of inference and, in general, of the structure of the justification of knowledge within the given situation. First, it is possible to extend L. Bonjour’s concept with the idea of the nonmonotonic nature of justification and coherence of the original system of beliefs. Such a step, in particular, will make it possible to abandon the need for the argument «from meta-justification». Second, the interpretation of «spontaneous beliefs», their justification and facts fixing whether these beliefs violate the coherence of the original system or not, as patterns (in the sense of the fundamental concept of existence by D. Ross) makes it possible (for example, due to the exact understanding of «interpretative perspective» and «functional role» of the projection) to meaningfully interpret the «context dependence» in each particular case.

Modest Infinitism -/- Jeremy Fantl -/- Abstract -/- Infinitism, a theory of justification most recently developed and defended by Peter Klein, is the view that justification is a matter of having an infinite series of non-repeating reasons for a proposition. I argue that infinitism is preferable to other theories (like foundationalism) in that only infinitism can plausibly account for two important features of justification: 1) that it admits of degrees and 2) that a concept of complete justification makes sense.

Indicators of the reliability of informants are essential for social learning in a society that is initially dominated by ignorance or superstition. Such reliability indicators should be based on meta-induction over records of truth-success. This is the major claim of this paper, and it is supported in two steps. One needs a non-circular justification of the method of meta-induction, as compared to other learning methods. An approach to this problem has been developed in earlier papers and (...) is reported in section 2. It is based on the predictive optimality of meta-inductive learning, under the assumption that objective success records are globally available. The rest of the paper develops an extension of this approach, so-called local meta-induction. Here individuals can access only success records of individuals in their immediate epistemic neighborhood. It is shown that local meta-inductive learning can spread reliable information over the entire population, and has clear advantages compared to success-independent social learning methods such as peer-imitation and authority-imitation.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Infinitists argue that their view outshines foundationalism because infinitism can, whereas foundationalism cannot, explain two of epistemic justification’s crucial features: it comes in degrees and it can be complete. I present four different ways that foundationalists could make sense of those two features of justification, thereby undermining the case for infinitism.

In a recent paper, Jeanne Peijnenburg and David Atkinson [ Studia Logica, 89:333-341 ] have challenged the foundationalist rejection of infinitism by giving an example of an infinite, yet explicitly solvable regress of probabilistic justification. So far, however, there has been no criterion for the consistency of infinite probabilistic regresses, and in particular, foundationalists might still question the consistency of the solvable regress proposed by Peijnenburg and Atkinson.

This paper discusses an analogical argument for the compatibility of the evidential argument from evil and skeptical theism. The argument is based on an alleged parallel between the paradox of the preface and the case of apparently pointless evil. I argue that the analogical argument fails, and that the compatibility claim is undermined by the epistemic possibility of inaccessible reasons for permitting apparently pointless evils. The analogical argument fails, because there are two crucial differences between the case of apparently pointless (...) evil and the case of the preface. First, in the preface case, our non-cumulative evidence supports a claim of error, whereas the analogical argument is based on the idea that our non-cumulative evidence supports the success claim that there’s at least one instance of truly pointless evil. Second, our non-cumulative evidence of error in the case of the preface rests on a track record establishing author fallibility; in the case of apparently pointless evils, there is no relevant track record to support the claim that some apparently pointless evils are truly pointless. These differences, together with certain plausible assumptions about our fallibility and reliability with respect to propositions about evil, also indicate that inaccessible reasons for permitting apparently pointless evil are epistemically possible. Given the epistemic possibility of such reasons, we’re in no position to judge whether such reasons are present in every case no matter how large the set of such evils may be. (shrink)

As we trace a chain of reasoning backward, it must ultimately do one of four things: (i) end in an unjustified belief, (ii) continue infinitely, (iii) form a circle, or (iv) end in an immediately justified basic belief. This article defends positism—the view that, in certain circumstances, type-(i) chains can justify us in holding their target beliefs. One of the assumptions that generates the epistemic regress problem is: (A) Person S is mediately justified in believing p iff (1) S has (...) a doxastic reason q for p and (2) S is justified in believing q. Assumption (A) presupposes that reasoning is only justification transmitting, not justification generating. The article rejects (A) and argues that, in certain circumstances, reasoning itself is justification generating, even if that from which one is reasoning is not itself justified. It concludes by comparing positism with its infinitist, coherentist, and foundationalist rivals, acknowledging what is right about these other views. (shrink)

Foundationalism in moral epistemology is a core tenet of ethical intuitionism. According to foundationalism, some moral beliefs can be known without inferential justification; instead, all that is required is a proper understanding of the beliefs in question. In an influential criticism against this view, Walter Sinnott-Armstrong has argued that certain psychological facts undermine the reliability of moral intuitions. He claims that foundationalists would have to show that non-inferentially justified beliefs are not subject to those defeaters, but this would already (...) constitute a form of inference and hence undermine the possibility of noninferential justification. The goal of my paper is to defend foundationalism against Sinnott-Armstrong’s criticism. After presenting his challenge, I first argue that the most promising objection to it fails. This objection makes the case that defeater-defeaters are not part of the justification, but merely preserve the justification which the original claim provides. I object to this argument by distinguishing between weak and robust defeaters; only weak defeaters, I argue, fall outside the scope of justification, and it is an open question whether Sinnott-Armstrong’s defeaters fall into that category. This leads the way to my own criticism of Sinnott-Armstrong’s challenge: foundationalists in moral epistemology are entitled to the use of defeater-defeaters as part of the justification for moral beliefs as long as those defeater-defeaters themselves do not entail moral claims. Therefore, Sinnott-Armstrong’s challenge does not undermine foundationalism. (shrink)

The background of this paper (section 1) consists in a new account to foundation‐theoretic epistemology characterized by two features: (i) All beliefs are to be justified by deductive, inductive or abductive inferences from a minimalistic class of unproblematic (introspective or analytic) basic beliefs. (ii) Higher‐order justifications for these inferences are given by means of the novel method of optimality justifications. Optimality justifications are a new tool for epistemology (section 2). An optimality justification does not attempt todemonstratethat a cognitive method is (...) reliable (which is impossible), but pursues the more modest goal of demonstrating that the method isoptimalamong all accessible alternative methods for the given epistemic goal. The reasoning from the established optimality of a method to the acceptability of a particular belief generated by the method is accomplished by so‐called optimality principles. In sections 3–5, the method of optimality justifications is carried out in detail for three fundamental problems: justifying induction, logic, and theory‐generating abduction. (shrink)

The ancient puzzle of the Liar was shown by Tarski to be a genuine paradox or antinomy. I show, analogously, that certain puzzles of contemporary game theory are genuinely paradoxical, i.e., certain very plausible principles of rationality, which are in fact presupposed by game theorists, are inconsistent as naively formulated. ;I use Godel theory to construct three versions of this new paradox, in which the role of 'true' in the Liar paradox is played, respectively, by 'provable', 'self-evident', and 'justifiable'. I (...) also construct in modal operator logic a paradox involving reflexive empirical reasoning. Unlike the paradox of the Liar, the paradox of reflexive reasoning does not depend on self-reference. ;I consider various solutions to the Liar paradox and evaluate how well these solutions cope with the paradox of reflexive reasoning. I then formalize the solution to the paradoxes which I favor: the indexical-hierarchical approach, first sketched out by Charles Parsons and Tyler Burge. In this solution, occurrences of the predicate 'true' in sentence-tokens are contextually relativized to levels of a hierarchy. Drawing also on some brief remarks of Bertrand Russell and Charles Parsons, I develop an account of the kind of schematic generality needed for this theory to be statable. ;Finally, I demonstrate that the principles shown to be paradoxical are in fact presupposed by contemporary game theorists in their reliance on the notion of common knowledge or, more precisely, mutual belief. I create novel analyses of and corresponding solutions to several recalcitrant puzzles within game theory, including the "chain-store paradox". (shrink)

Consider the following process of epistemic justification: proposition $E_{0}$ is made probable by $E_{1}$ which in turn is made probable by $E_{2}$ , which is made probable by $E_{3}$ , and so on. Can this process go on indefinitely? Foundationalists, coherentists, and sceptics claim that it cannot. I argue that it can: there are many infinite regresses of probabilistic reasoning that can be completed. This leads to a new form of epistemic infinitism.

Any satisfactory epistemology must account for the distinction between propositional and doxastic justification. Can infinitism account for it? Proposals to date have been unsatisfactory. This paper advances a new infinitist account of the distinction. The discussion proceeds as follows. Section 1 sets the stage. Section 2 presents Peter Klein's account. Section 3 raises a problem for Klein's account and suggests an improvement. Section 4 raises a further challenge. Sections 5 to 7 consider several unsuccessful attempts to meet the challenge. Section (...) 8 presents my new proposal, which can meet the challenge. Section 9 concludes the discussion. (shrink)

I propose a version of foundationaUsm with the following distinctive features. First, it includes in the class of basic beliefs ordinary beliefs about physical objects. This makes it unrestricted. Second, it assigns the role of ultimate justifiers to A-states: states of being appeared to in various ways. Such states have propositional content, and are justifiers if they are presumptively reliable. The beliefs A-states justify are basic if they are non-inferential. In the last three sections of the paper, I defend this (...) version of foundationalism against Sellars's famous anti-foundationalist dilemma, according to which sense-experiential states can't be justifiers ifthey lack propositional content, and can't terminate the justificatory regress if they have propositional content. I argue that the latter of these two claims is false. A-states can play the role of justifiers because they have propositional content, and they can terminate the justificatory regress because they themselves are capable of neither being true or false, nor being justified or unjustified.

Background: Differential learning is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed, Web (...) of Science, and Google Scholar were searched until February 3, 2020. To be included, studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method, studies had to describe the effects on one or more measures of performance in a skill or movement task, and the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase as well as for the retention phase was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found. (shrink)

The article analyses the meta- epistemological problem of the justification of a theory of knowledge. The first section is dedicated to the morphological reconstruction of the problem, the second presents a diagnosis of the problem in terms of a metatheoretical and logically non- contradictory "petitio principii" and the third delineates the limits within which strategies for the treatment of the problem could be elaborated.

This thesis examines philosophical controversies surrounding the evaluation of medical treatments, with a focus on the evidential roles of randomised trials and mechanisms in Evidence-Based Medicine. Current 'best practice' usually involves excluding non-randomised trial evidence from systematic reviews in cases where randomised trials are available for inclusion in the reviews. The first paper challenges this practice and evaluates whether adding of evidence from non-randomised trials might improve the quality and precision of some systematic reviews. The second paper (...) compares the alleged methodological benefits of randomised trials over observational studies for investigating treatment benefits. It suggests that claims about the superiority of well-conducted randomised controlled trials over well-conducted observational studies are justified, especially when results from the two methods are contradictory. The third paper argues that postulating the unpredictability paradox in systematic reviews when no detectable empirical differences can be found requires further justification. The fourth paper examines the problem of absence causation in the context of explaining causal mechanisms and argues that a recent solution is incomplete and requires further justification. Solving the problem by describing absences as causes of 'mechanism failure' fails to take into account the effects of absences that lead to vacillating levels of mechanism functionality. The fifth paper criticises literature that has emphasised functioning versus 'broken' or 'non-functioning' mechanisms emphasising that many diseases result from increased or decreased mechanism function, rather than complete loss of function. Mechanistic explanations must account for differences in the effectiveness of performed functions, yet current philosophical mechanistic explanations do not achieve this. The last paper argues that the standard of evidence embodied in the ICE theory of technological function is too permissive for evaluating whether the proposed functions of medical technologies have been adequately assessed and correctly ascribed. It argues that high-quality evidence from clinical studies is necessary to justify functional ascriptions to health care technologies. (shrink)
