I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

O propósito deste artigo é mostrar como podem ser desenvolvidas explicações robustas de justificação e de certeza no interior do infinitismo. Primeiro, eu explico como a concepção infinitista de justificação epistêmica difere das concepções fundacionista e coerentista. 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)

The purpose of this paper is to explain how infinitism—the view that reasons are endless and non-repeating—solves the epistemic regress problem and to defend that solution against some objections. The first step is to explain what the epistemic regress problem is and, equally important, what it is not. Second, I will discuss the foundationalist and coherentist responses to the regress problem and offer some reasons for thinking that neither response can solve the problem, no matter how they are tweaked. Then, (...) I want to present the infinitist solution to the problem and defend it against some of the well known objections to it. (shrink)

Most analytic epistemologists, foundationalists and coherentists alike, have rejected the possibility of an infinitely long, non-recurring regress of justified beliefs. it is instructive to inquire why this notion has received nearly universal condemnation. in a review of recent work six sorts of arguments against infinite justificatory chains are examined. it is concluded firstly that, while regresses in which each belief is justified solely via relations to further beliefs cannot exist, the impossiblity of other sorts of infinite justificatory chains has not (...) been shown, and secondly that there may nevertheless be sound methodological reasons for provisionally rejecting the infinite regress possibility while more satisfactory alternatives are explored.

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.

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.

This article discusses contemporary response to the epistemic regress problem or Agrippa's trilemma. The epistemic regress problem is considered the most crucial in the entire theory of knowledge and it is a major concern for many contemporary epistemologists. However, only two of the three alternative solutions have been developed in any detail, foundationalism and coherentism. Infinitism was not seriously considered as a solution because of the finite-mind objection. This article also provides a brief evaluation of foundationalism, emergent coherentism, and infinitism.

This paper argues for a completely universal scepticism, according to which no beliefs at all are justified to the least degree. The argument starts with a version of the Agrippan trilemma, according to which, if we accept that a belief is justified, we must choose between foundationalism, coherentism of a particular sort, and an infinite regress of justified beliefs. Each of these theories is given a careful specification in terms of the relationship of “justifiedness in p depending on justifiedness in (...) q”. It is then argued that no beliefs – not even beliefs about phenomenal experiences – are foundational in the required way. Both coherentism and infinitism are untenable, since, since they face various objections, most significantly the objection that acceptance of either would commit one to allowing that all beliefs were justified. Because the three possible accounts of justificational structure all fail radically, it is concluded that no beliefs are justified. (shrink)
