One of the many problems that would have t o be solved by a satisfactory theory of empirical knowledge, perhaps the most central is a general structural problem which I shall call the epistemic regress problem: the problem of how to avoid an in- finite and presumably vicious regress of justification in ones account of the justifica- tion of empirical beliefs. Foundationalist theories of empirical knowledge, as we shall see further below, attempt t o avoid the regress by locating a (...) class of empirical beliefs whose justification does not depend on that of other empirical beliefs. Extemalist theories, the topic of the present paper, represent one species of foundationalism. (shrink)

Perhaps the most pervasive conviction within the Western epistemological tradition is that in order for a belief to constitute knowledge it is necessary that it be epistemically justified: that the person in question have a reason or warrant which makes it at least highly likely that the belief is true. Historically, most epistemologists have distinguished two main sources from which such justification might arise. It has seemed obvious to all but a very few that many beliefs are justified by appeal (...) to one’s experience of the world. But it has seemed equally obvious to most that there are other beliefs, including many of the most important ones that we have, which are justified in a way which is entirely independent of any appeal to such experience, justified, as it is usually put, a priori, by reason or pure thought alone.

A comprehensive defence of the rationalist view that insight independent of experience is a genuine basis for knowledge.

Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge. Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate. Introduces students to fundamental questions within (...) epistemology while engaging in contemporary debates. Written by two of today’s foremost epistemologists. Includes an extensive bibliography.

In Epistemology, Laurence Bonjour introduces the serious philosophy student to the history and concepts of epistemology, while simultaneously challenging them to take an active part in its ongoing debates. The text reflects BonJour's conviction that the place to start any discussion of the theories of knowledge is with the classical problems, beginning with and centered around Descartes.

Introduction -- Part I: The classical problems of epistemology -- Descartes's epistemology -- The concept of knowledge -- The problem of induction -- A priori justification and knowledge -- Immediate experience -- Knowledge of the external world -- Some further epistemological issues : other minds, testimony, and memory -- Part II: Contemporary responses to the cartesian epistemological program -- Introduction to part II -- Foundationalism and coherentism -- Internalism and externalism -- Quine and naturalized epistemology -- Knowledge and skepticism.

This book is concerned with the alleged capacity of the human mind to arrive at beliefs and knowledge about the world on the basis of pure reason without any dependence on sensory experience. Most recent philosophers reject the view and argue that all substantive knowledge must be sensory in origin. Laurence BonJour provocatively reopens the debate by presenting the most comprehensive exposition and defence of the rationalist view that a priori insight is a genuine basis for knowledge. This (...) important book will be at the centre of debate about the theory of knowledge for many years to come. (shrink)

My aim in this paper is to explore the dispute between foundationalism and coherentism and attempt a resolution. I will begin by considering the origin of the issue in the famous epistemic regress problem. Next I will explore the central foundationalist idea and the most central objections that have been raised against foundationalist views. This will lead to a consideration of the main contours of the coherentist alternative, and eventually to a discussion of objections to coherentism – including several specific (...) ones that I now judge to be clearly fatal, especially when taken together. This will motivate, finally, a reconsideration of foundationalism. I will argue that the dialectically most serious objection to foundationalism can be successfully answered. While the answer that I will suggest admittedly carries with it the price of aggravating certain other difficulties, especially the venerable problem of showing how belief in an external world of physical objects can be justified, it still seems to me to leave foundationalism as by far the more defensible and promising of the two alternatives.

In “Internalism and Externalism,” Laurence BonJour suggests that the contemporary epistemological debate over internalism and externalism concerns the formulation of the justification or warrant condition in an account of knowledge. The internalist requires that for a belief to meet this condition, all of the necessary elements must be cognitively accessible to the believer, whereas the externalist claims that at least some such elements do not need to be accessible to the believer. BonJour gives an overview of this (...) dispute. He suggests that the opposition between the two views is less straightforward than has usually been thought. He proposes, in addition, that each of them has valuable roles to play in major epistemological issues, even though the internalist approach is more fundamental in an important way. (shrink)

It is fairly standard in accounts of the epistemology of perceptual knowledge to distinguish three main alternative positions: representationalism, phenomenalism, and a third view that is called either naïve realism or direct realism. I have always found the last of these views puzzling and elusive. My aim in this paper is to try to figure out what direct realism amounts to, mainly with an eye to seeing whether it offers a genuine epistemological alternative to the other two views and to (...) representationalism in particular. My main thesis will be that it does not—that what is right in direct realist views turns out to have little bearing on the central epistemological issue concerning perceptual knowledge. (shrink)

The historically most central epistemological issue concerning perception, to which this article will be almost entirely devoted, is whether and how beliefs about physical objects and about the physical world generally can be justified or warranted on the basis of sensory or perceptual experience—where it is internalist justification, roughly having a reason to think that the belief in question is true, that is mainly in question (see the entry justification, epistemic: internalist vs. externalist conceptions of). This issue, commonly referred to (...) as “the problem of the external world,” divides into two closely related sub-issues, which correspond to the first two main sections below. The first of these issues has to do with the nature of sensory experience and its relation to the physical world; it is typically (though as we shall see not altogether perspicuously) formulated as the question of what are the immediate objects of awareness in sensory experience or, in a variant but essentially equivalent terminology, of what is given in such experience. Perhaps the most historically standard, though not currently the most popular answer to this question has been that it is sense-data (private, non-physical entities that actually have the immediately experienced sensory qualities) that are the immediate objects of awareness or that are given. The second issue has to do with the way in which beliefs about the physical world are justified on the basis of such sensory experience. If it is concluded that physical objects are not themselves given, the two main answers to this question are representationalism or indirect realism (the view that the immediate objects of experience represent or depict physical objects in a way that allows one to infer justifiably from such experience to the existence of the corresponding “external” objects) and phenomenalism (the view..

My purpose in this paper is to discuss and defend an objection to physicalist or materialist accounts of the mind.

In this paper I am primarily interested in establishing that a coherence theory of truth is conceptually incoherent. Although my primary concern is with the coherence theory of truth, I shall point out that the problem I raise has a striking parallel in a now well-known objection to coherence theories of justification (an objection that, ironically, was brought to the fore by a proponent of a coherence theory of justification, Laurence Bonjour).

Em “O Mito do Conhecimento”, Laurence BonJour defende a tese de que a concepção “falibilista” de conhecimento, assumida de modo preponderante pelos epistemólogos na era pós-Gettier, “está errada”, pois tal concepção “fraca” de conhecimento proporciona pouca satisfação da perspectiva filosófica e é inexistente no âmbito do senso comum, constituindo tão-somente um “mito filosófico”.
