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.

There has been an explosion of interest in the metaphysics of fundamentality in recent decades. The consensus view, called metaphysical foundationalism, maintains that there is something absolutely fundamental in reality upon which everything else depends. However, a number of thinkers have chal- lenged the arguments in favor of foundationalism and have proposed competing non-foundationalist ontologies. This paper provides a systematic and critical introduction to metaphysical foundationalism in the current literature and argues that its relation to ontological dependence and substance should (...) be qualified in important ways.

According to Realism about Epistemic Value, there is such a thing as epistemic value and it is appropriate to evaluate things—e.g., beliefs—for epistemic value because there is such a thing as epistemic value. Allan Hazlett's A Luxury of the Understanding is a sustained critique of Realism. Hazlett challenges proponent of Realism to answer explanatory questions while not justifiably violating certain constraints, including two proposed naturalistic constraints. Hazlett argues they cannot. Here I defend Realism. I argue that it is easy for (...) proponents of Realism to answer Hazlett's explanatory questions. The interesting issue is whether those answers violate Hazlett's naturalistic constraints. My own view is that epistemic value is irreducible to natural properties; it thus violates Hazlett's proposed constraints. I argue that this is justifiable because Hazlett fails to convincingly motivate his naturalistic constraints and there is reason for thinking epistemic value is irreducible to natural properties anyway.

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments shows that we must distinguish different types (...) of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

This paper examines two objections to the infinitist theory of epistemic justification, namely “the finite mind objection” and “the distinction objection.” It criticizes Peter Klein’s response to the distinction objection and offers a more plausible response. It is then argued that this response is incompatible with Klein’s response to the finite mind objection. Infinitists, it would seem, cannot handle both objections when taken together.

Once one accepts that certain things metaphysically depend upon, or are metaphysically explained by, other things, it is natural to begin to wonder whether these chains of dependence or explanation must come to an end. This essay surveys the work that has been done on this issue—the issue of grounding and infinite descent. I frame the discussion around two questions: (1) What is infinite descent of ground? and (2) Is infinite descent of ground possible? In addressing the second question, I (...) will consider a number of arguments that have been made for and against the possibility of infinite descent of ground. When relevant, I connect the discussion to two important views about the way reality can be structured by grounding: metaphysical foundationalism and metaphysical infinitism. (shrink)

Turri argues against what he calls an “orthodox” view of the relationship between propositional and doxastic justification, according to which (Basis) it is sufficient for S to be doxastically justified in believing p that p is propositionally justified for S in virtue of having reason(s) R and S believes p on the basis of R. According to Turri, (Basis) is false and hence the orthodox view is wrong. Turri offers “an alternative proposal,” the definitive thesis of which is that the (...) subject’s intellectual abilities explain why a given proposition, p, is justified for her, and argues that, contra the orthodoxy, this proposal leads to explaining propositional justification in terms of doxastic justification rather than vice versa. In this paper, I argue for the following claims: (i) There are good reasons to think that Turri misidentifies “the orthodox view” and his objection thereby misfires, (ii) Even if we assume that Turri’s identification of the orthodox view is correct, his counter-examples to that view are far from being decisive, and (iii) Turri’s own proposal is not “an alternative” to the orthodox view but can be accommodated by it.

There is an important disagreement in contemporary epistemology over the possibility of non-epistemic reasons for belief. Many epistemologists argue that non-epistemic reasons cannot be good or normative reasons for holding beliefs: non-epistemic reasons might be good reasons for a subject to bring herself to hold a belief, the argument goes, but they do not offer any normative support for the belief itself. Non-epistemic reasons, as they say, are just the wrong kind of reason for belief. Other epistemologists, however, argue that (...) there can be cases where non-epistemic reasons directly offer normative support for the beliefs a subject holds. -/- My aim in this paper is to remove an apparent obstacle for the view that there can be non-epistemic normative reasons for belief, by showing that the existence of non-epistemic reasons for belief does not conflict with epistemic standards for the assessment of inference. More specifically, I aim to show that the following principles are compatible: -/- Epistemic Norm of Inference (ENI): Necessarily, for all subjects, S, and inferences, I: I is a good inference for S only if S can gain a (doxastically) epistemically justified belief in I’s conclusion on the basis of I’s premises. -/- Non-Epistemic Reasons for Belief (NERB): Possibly, for some subject, S, reason, R, and belief, B: R is a good (i.e., normative) reason for S to hold B, and R is not an epistemic reason for B. -/- Guidance: For all subjects S, potential reasons R, and beliefs/actions φ: In order for R to count as a normative reason for S to φ, it must be possible for S to take R into account as relevant to the determination of whether S ought to φ. -/- One might naturally think that these principles conflict, for if there are non-epistemic reasons for belief, then they must guide deliberation, and in guiding deliberation, they would violate epistemic standards. The aim of this paper is to show that no such conflict need arise. -/- Section 2 of the paper proceeds to set out the concept of an inference, and to sketch an epistemic framework for the assessment of inferences and arguments. Section 3 sets out the distinction between normative and motivating reasons, and briefly defends the view that there can be non-epistemic reasons for beliefs. Section 4 shows that non-epistemic reasons for belief are compatible with epistemic standards for inference, because any time a reason R is a good non-epistemic reason for a subject S to hold a belief B, there is an epistemically good inference available to S which takes R as a premise and which concludes with the meta-belief that S ought to hold B. So the paper employs a level-connecting principle between normative reasons for φ-ing and epistemic reasons for believing that one ought to φ. The paper ends with clarifications of that level-connecting principle, and responses to three objections. (shrink)

Many take the claim that you cannot ‘get’ an ‘ought’ from an ‘is’ to imply that non- moral beliefs are by themselves incapable of justifying moral beliefs. I argue that this is a mistake and that the position that moral beliefs are justified exclusively by non-moral beliefs—a view that I call moral inferentialism—presents an attractive non-sceptical moral epistemology.

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 a series of papers, Adam Leite has developed a novel view of justification tied to being able to responsibly justify a belief. Leite touts his view as faithful to our ordinary practice of justifying beliefs, providing a novel response to an epistemological problem of the infinite regress, and resolving the “persistent interlocutor” problem. Though I find elements of Leite’s view of being able to justify a belief promising, I hold that there are several problems afflicting the overall picture of (...) justification. In this paper, I argue that despite its ambitions, Leite’s view fails to solve the persistent interlocutor problem and does not avoid a vicious regress. (shrink)

The notion of fundamentality, as it is used in metaphysics, aims to capture the idea that there is something basic or primitive in the world. This metaphysical notion is related to the vernacular use of “fundamental”, but philosophers have also put forward various technical definitions of the notion. Among the most influential of these is the definition of absolute fundamentality in terms of ontological independence or ungroundedness. Accordingly, the notion of fundamentality is often associated with these two other technical notions.

ABSTRACT This essay presents the chief reasons for making a distinction between propositional and doxastic justification and, also, points out two things: no theory of propositional justification implies a theory of doxastic justification; infinitism is, essentially, a theory of propositional justification. Additionally, this paper tries to shed some light on the three conjointly sufficient conditions for a proper infinitist view of propositional justification.

Resumo: Neste artigo, apresentamos uma versão de uma teoria que eu chamarei de Contextualismo Epistêmico ‒ a visão de que o contexto e os padrões determinados por ele desempenham um papel central na avaliação de se um agente epistêmico tem, ou não, justificação e, portanto, conhecimento ‒ para tentar resolver um dos problemas mais influentes em epistemologia, a saber, o Problema do Regresso epistêmico. O primeiro passo será o de caracterizar o problema do regresso epistêmico. 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. Palavras-chave: Regresso Epistêmico, Justificação, Conhecimento, Contextualismo Epistêmico. 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)

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.

Can a perceptual experience justify (epistemically) a belief? More generally, can a nonbelief justify a belief? Coherentists answer in the negative: Only a belief can justify a belief. A perceptual experience can cause a belief but cannot justify a belief. Coherentists eschew all noninferential justification—justification independent of evidential support from beliefs—and, with it, the idea that justification has a foundation. Instead, justification is holistic in structure. Beliefs are justified together, not in isolation, as members of a coherent belief system. The (...) main question of the paper is whether coherentism is consistent. I set out an apparent inconsistency in coherentism and then give a resolution to that apparent inconsistency. (shrink)

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)

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)

This article aims to provide a structural analysis of the problems related to the easy knowledge problem. The easy knowledge problem is well known. If we accept that we can have basic knowledge via a source without having any prior knowledge about the reliability or accuracy of this source, then we can acquire knowledge about the reliability or accuracy of this source too easily via information delivered by the source. Rejecting any kind of basic knowledge, however, leads into an infinite (...) regress and, plausibly, to skepticism. The article argues that the third alternative, accepting basic knowledge but rejecting easy knowledge, entails closure failure. This is obviously the case for deductive bootstrapping, but, notably, the problem also arises for inductive bootstrapping. Hence, the set of problems related to the easy knowledge problem has the structure of a trilemma. We are forced to accept easy knowledge, closure failure, or skepticism. (shrink)

Discussion of a metaphysical sense of 'inheritance' and cognate notions relevant to fundamentality.

Infinitism is an ancient view in epistemology about the structure of knowledge and epistemic justification, according to which there are no foundational reasons for belief. The view has never been popular, and is often associated with skepticism, but after languishing for centuries it has recently begun a resurgence. Ad Infinitum presents new work on the topic by leading epistemologists. They shed new light on infinitism's distinctive strengths and weaknesses, and address questions, new and old, about its account of justification, reasoning, (...) epistemic responsibility, disagreement, and trust, among other important issues. The volume clarifies the relationship between infinitism and other epistemological views, such as skepticism, coherentism, foundationalism and contextualism, and it offers novel perspectives on the metaphysics, epistemology, and ethics of regresses and reasons.

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 is about metaphysical ‘infinitism’, the view that there are, or could be, infinite chains of ontological dependence. Its main aim is to show that, contrary to widespread opinion, metaphysical infinitism is a coherent position. On the basis of this, it is then additionally argued that metaphysical infinitism need not fare worse than the more canonical ‘foundationalist’ alternatives when it comes to formulating metaphysical explanations. In the course of the discussion, a rather unexplored parallel with the debate concerning infinitism (...) about justification is suggested. (shrink)

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

According to Peter Klein, foundationalism fails because it allows a vicious form of arbitrariness. The present article critically discusses his concept of arbitrariness. It argues that the condition Klein takes to be necessary and sufficient for an epistemic item to be arbitrary is neither necessary nor sufficient. It also argues that Klein's concept of arbitrariness is not a concept of something that is obviously vicious. Even if Klein succeeds in establishing that foundationalism allows what he regards as arbitrariness, this does (...) not yet mean that he confronts it with a sound objection. (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)

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.

This thesis offers a naturalist revision of Alain Badiou’s philosophy. This goal is pursued through an encounter of Badiou’s mathematical ontology and theory of truth with contemporary trends in philosophy of mathematics and philosophy of science. I take issue with Badiou’s inability to elucidate the link between the empirical and the ontological, and his residual reliance on a Heideggerian project of fundamental ontology, which undermines his own immanentist principles. I will argue for both a bottom-up naturalisation of Badiou’s philosophical approach (...) to mathematics and a top-down naturalisation. Articulating my particular understanding of what realism and naturalism should commit us to, I propose a creative fusion of Badiou’s attention to metamathematical results with a structural-informational metaphysics, proposing a ‘matherialism’ uniting the more daring speculative insights of the former with the naturalist and empiricist commitments motivating the latter.

Neste artigo eu ofereço uma nova abordagem para resolução do problema do regresso epistêmico. Tal problema pode ser considerado um dos mais tradicionais problemas em epistemologia, que nos segue desde a antiguidade. As teses tradicionais que tentam responder a este problema possuem dificuldades ainda não respondidas satisfatoriamente, fato que, inicialmente, serve de motivação para a procura de uma nova resposta. Primeiramente, apresento o problema do regresso epistêmico e as respostas tradicionais oferecidas na sua resolução. Como veremos todas elas possuem problemas (...) sérios que comprometem a plausibilidade das mesmas, a saber, (i) não respondem adequadamente quando é apropriado interromper o regresso e (ii) não especificam ou determinam o grau de justificação requerido para o conhecimento. Em seguida, eu argumentarei em favor da tese que chamarei de Contextualismo Justificacionista, mostrando que ela consegue responder adequadamente (i) e (ii). (shrink)

According to Agrippa's trilemma, an attempt to justify something leads to either infinite regress, circularity, or dogmatism. This essay examines whether and to what extent the trilemma applies to ethics. There are various responses to the trilemma, such as foundationalism, coherentism, contextualism, infinitism, and German idealism. Examining those responses, the essay shows that the trilemma applies at least to rational justification of contentful moral beliefs. This means that rationalist ethics based on any contentful moral belief are rationally unjustifiable.

This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

Infinite regress arguments play an important role in many distinct philosophical debates. Yet, exactly how they are to be used to demonstrate anything is a matter of serious controversy. In this paper I take up this metaphilosophical debate, and demonstrate how infinite regress arguments can be used for two different purposes: either they can refute a universally quantified proposition (as the Paradox Theory says), or they can demonstrate that a solution never solves a given problem (as the Failure Theory says). (...) In the meantime, I show that Black’s view on infinite regress arguments (1996, this journal) is incomplete, and how his criticism of Passmore can be countered. (shrink)

This note employs the recently established consistency theorem for infinite regresses of probabilistic justification (Herzberg in Stud Log 94(3):331–345, 2010) to address some of the better-known objections to epistemological infinitism. In addition, another proof for that consistency theorem is given; the new derivation no longer employs nonstandard analysis, but utilises the Daniell–Kolmogorov theorem.

I evaluate two new objections to an infinitist account of epistemic justification, and conclude that they fail to raise any new problems for infinitism. The new objections are a refined version of the finite-mind objection, which says infinitism demands more than finite minds can muster, and the normativity objection, which says infinitism entails that we are epistemically blameless in holding all our beliefs. I show how resources deployed in response to the most popular objection to infinitism, the original finite-mind objection, (...) can be redeployed to address the two new objections. (shrink)

Disjunctivism is the view that perceptual experience is either constituted by fact in the world or mere appearance. This view is said to be able to guarantee our cognitive contact with the world, and thus remove a crucial “prop” upon which skepticism depends. This paper has two aims. First, it aims to show that disjunctivism is a solution to Cartesian skepticism. Cartesian skepticism is an epistemological thesis, not an ontological one. Therefore, if there is an external world, we may well (...) undergo a veridical experience, and thus we can take advantage of disjunctivism to adopt an anti-evidential-skepticism strategy to counter Cartesian skepticism. Second, this paper argues that disjunctivism fails to solve Pyrrhonian skepticism. To counter Pyrrhonian skepticism, one has to give reasons both for his belief and for his believing. But disjunctivism can only account the former, that is, the reason for the content of perceptual belief. Given that one’s experience in good case and bad case is subjectively indistinguishable, one cannot just use his experience to justify his believing. This shows that disjunctivism cannot meet the requirement to provide an adequate account for reflective knowledge. (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.

Na primeira parte deste estudo, defendemos que a afirmação de que um sujeito S crê que ϕ com base em boas razões não pode ser o único tipo de explicação para o fato de que S racionalmente crê que ϕ. Explicar atribuições de racionalidade somente por meio da noção de uma crença baseada em boas razões gera uma versão do problema do regresso das razões. Na segunda parte, apresentamos uma hipótese de acordo com a qual algumas crenças são racionalmente mantidas (...) por um sujeito S em virtude do fato de que S sabe como produzir boas razões para sustentá-las. Na terceira parte, oferecemos razões para aceitar a hipótese relevante e argumentamos que ela é superior a teorias fundacionistas e coerentistas ao explicar a verdade de algumas atribuições de racionalidade. Na última parte do artigo, tratamos do problema do regresso das razões e esboçamos uma solução para tal problema, a partir de nossa hipótese. (shrink)

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.

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. (shrink)

In the first part of this paper, we argue that the claim that a subject S believes that ϕ on the basis of good reasons cannot be the only type of explanation why S rationally believes that ϕ. Explaining attributions of rationality only by means of the notion of a belief being based on good reasons generates one version of the problem of regress of reasons. In the second part we flesh out a hypothesis according to which some beliefs are (...) rationally held by a subject S in virtue of the fact that S knows how to produce good reasons for holding them. In the third part we offer reasons for accepting the relevant hypothesis, and we argue that it is more successful than foundationalist, coherentist and infinitist theories in explaining the truth of some attributions of epistemic rationality. In the last part we address the problem of the regress of reasons and sketch a solution for it based on our hypothesis. (shrink)

In this paper, I deal with a version of the epistemic regress problem. After rejecting foundationalism as a solution to it, I consider two versions of infinitism. The first one is found to be unacceptable, for it fails both to cohere with certain attributions of justification and also to maintain its internal coherence. The second one avoids both problems, and it is found to be the best way of addressing the epistemic regress problem. As the successful version of infinitism makes (...) use of the notion of a rational disposition to form and deploy reasons, I also manage to explicate that notion. (shrink)

The purpose of this essay is to show that the version of epistemological infinitism defended by Peter Klein is externalistic in character. I present the most important questions infinitism is supposed to resolve and also present the fundamental difference regarding internalism and externalism in epistemology. I conclude with an indication of what would be the best way to understand infinitism and how to evade the problems that emerge from Klein’s externalist infinitism.

O propósito deste ensaio é mostrar que a versão de infinitismo epistemológico defendida por Peter Klein é uma forma de externalismo. São apresentados os problemas mais importantes que o infinitismo deve resolver e também a diferença fundamental entre internalismo e externalismo em epistemologia. Como conclusão, é apresentada uma indicação sobre a melhor maneira de entender o infinitismo e como superar os problemas que surgem da forma externalista de infinitismo defendida por Klein.

This article poses two regresses for justification of moral knowledge and discusses three models for moral epistemic infinitism that arise. There are moral infinitisms dependent on empirical infinitism, what are called “piggyback” moral infinitisms. There are substantive empiricist moral infinitisms, requiring infinite chains of descriptive facts to justify normative rules. These empiricist infinitisms are developed either as infinitist egoisms or as infinitist sentimentalisms. And, finally, there are substantive rationalist moral infinitisms, requiring infinite chains of normative reasons to justify moral rules. (...) Rationalist moral infinitism is posed as a mixed view integrating moral intuitions with the demand for justifying reasons. (shrink)

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)

Abstract Epistemic infinitism is certainly not a majority view in contemporary epistemology. While there are some examples of infinitism in the history of philosophy, more work needs to be done mining this history in order to provide a richer understanding of how infinitism might be formulated internal to different philosophical frameworks. Accordingly, we argue that the philosophy of Emmanuel Levinas can be read as operating according to an ?impure? model of epistemic infinitism. The infinite obligation inaugurated by the ?face to (...) face encounter? with the Other yields an approach to the ethics of belief that accords with infinitism. This reading of Levinas brings his ethical thought into dialogue with contemporary epistemology as well as provides an historical example of infinitism within the current debates. (shrink)
