Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition.Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the (...) criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge.Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists. (shrink)

Plantinga examines the nature of epistemic warrant; whatever it is that when added to true belief yields knowledge. This volume surveys current contributions to the debate and paves the way for his owm positive proposal in Warrant and Proper Function.

Having adequate knowledge of the world is not just a matter of survival but also one of obligation. This obligation to "know well" is what philosophers have termed "epistemic responsibility." In this innovative and eclectic study, Lorraine Code explores the possibilities inherent in this concept as a basis for understanding human attempts to know and understand the world and for discerning the nature of intellectual virtue. By focusing on the idea that knowing is a creative process guided by imperatives of (...) epistemic responsibility, Code provides a fresh perspective on the theory of knowledge. From this new perspective, Code poses questions about knowledge that have a different focus from those traditionally raised in the two leading epistemological theories, foundationalism and coherentism. While not rejecting these approaches, this new position moves away from a primary concentration on determinate products and towards an examination of ever-changing processes. Arguing that knowledge never exists as an ungrounded abstraction but rather emerges through dialogue between variously authoritative "knowers" situated within particular social and historical contexts, she draws extensively on examples from lived social experience to illustrate the ways in which human beings have long tried to recognize and meet their epistemic responsibilities. This edition of Epistemic Responsibility includes a new preface from Lorraine Code"--Provided by the publisher. (shrink)

A detailed account of certain traits of intellectual character—the epistemic virtues—and of their relation to the responsibility for one's beliefs.

How much should your confidence in your beliefs be shaken when you learn that others – perhaps 'epistemic peers' who seem as well-qualified as you are – hold beliefs contrary to yours? This article describes motivations that push different philosophers towards opposite answers to this question. It identifies a key theoretical principle that divides current writers on the epistemology of disagreement. It then examines arguments bearing on that principle, and on the wider issue. It ends by describing some outstanding questions (...) that thinking about this issue raises. (shrink)

My conclusion will be that, more often than we might have thought, suspension of judgment is the epistemically proper attitude. It follows that in such cases we lack reasonable belief and so, at least on standard conceptions, knowledge. This is a kind of contingent real-world skepticism that has not received the attention it deserves. I hope that this paper will help to bring this issue to life.

I argue that its appearing to you that P does not provide justification for believing that P unless you have independent justification for the denial of skeptical alternatives – hypotheses incompatible with P but such that if they were true, it would still appear to you that P. Thus I challenge the popular view of ‘dogmatism,’ according to which for some contents P, you need only lack reason to suspect that skeptical alternatives are true, in order for an experience as (...) of P to justify belief that P. I pursue three lines of objection to dogmatism, having to do with probabilistic reasoning, considerations of future or hypothetically available justification, and epistemic circularity. I briefly sketch a fall-back position which avoids the problems raised. (shrink)

From the ferment of recent debates about the intellectual virtues, Roberts and Wood develop an approach they call 'regulative epistemology', exploring the connection between knowledge and intellectual virtue. In the course of their argument they analyse particular virtues of intellectual life - such as courage, generosity, and humility - in detail.

Richard Swinburne offers an original treatment of a question at the heart of epistemology: what makes a belief rational, or justified in holding? He maps the rival accounts of philosophers on epistemic justification ("internalist" and "externalist"), arguing that they are really accounts of different concepts. He distinguishes between synchronic justification (justification at a time) and diachronic justification (synchronic justification resulting from adequate investigation)--both internalist and externalist. He also argues that most kinds of justification are worth having because they are indicative (...) of truth; however, it is only justification of internalist kinds that can guide a believer's actions. Swinburne goes on to show the usefulness of the probability calculus in elucidating how empirical evidence makes beliefs probably true. (shrink)

Since the publication of Edmund Gettier's challenge to the traditional epistemological doctrine of knowledge as justified true belief, Roberts and Wood claim that epistemologists lapsed into despondency and are currently open to novel approaches. One such approach is virtue epistemology, which can be divided into virtues as proper functions or epistemic character traits. The authors propose a notion of regulative epistemology, as opposed to a strict analytic epistemology, based on intellectual virtues that function not as rules or even as skills (...) but as habits of the heart. To that end, they divide the task of clarifying and expounding their notion in the book's two parts.In the first part, Roberts and Wood examine various components that constitute their notion of regulative epistemology. The first are the epistemic goods or goals that drive the epistemic process. What is needed, claim Roberts and Wood, is an enriched notion of these goods rather than the restricted notion of justified true belief. Epistemic agents are more than calculating devices in that ….

To what degree should we rely on our own resources and methods to form opinions about important matters? To what degree should we depend on various authorities, such as a recognized expert or a social tradition? In this provocative account of intellectual trust and authority, Richard Foley argues that it can be reasonable to have intellectual trust in oneself even though it is not possible to provide a defence of the reliability of one's faculties, methods and opinions that does not (...) beg the question. Moreover, he shows how this account of intellectual self-trust can be used to understand the degree to which it is reasonable to rely on alternative authorities. This book will be of interest to advanced students and professionals working in the fields of philosophy and the social sciences as well as anyone looking for a unified account of the issues at the centre of intellectual trust.

C. C. W. Taylor presents a clear and faithful new translation of one of the most famous and influential texts in the history of Western thought, accompanied by an analytical and critical commentary focusing on philosophical issues. In Books II to IV of the Nicomachean Ethics Aristotle gives his account of virtue of character, which is central to his ethical theory as a whole and a key topic in much modern ethical writing.

This article traces a growing interest among epistemologists in the intellectuals of epistemic virtues. These are cognitive dispositions exercised in the formation of beliefs. Attempts to give intellectual virtues a central normative and/or explanatory role in epistemology occur together with renewed interest in the ethics/epistemology analogy, and in the role of intellectual virtue in Aristotle's epistemology. The central distinction drawn here is between two opposed forms of virtue epistemology, virtue reliabilism and virtue responsibilism. The article develops the shared and distinctive (...) claims made by contemporary proponents of each form, in their respective treatments of knowledge and justification. (shrink)

This chapter points out that standard versions of virtue epistemology accept and are motivated by the same central problems in epistemology — such as analyzing the concepts of knowledge and justification, and addressing skeptical challenges — which motivate contemporary epistemology. The only significant difference is that virtue epistemology claims that the concepts of knowledge and justification must be analyzed in terms of virtues. What motivates virtue ethicists, however, is not what is motivating other ethicists. The contemporary census amongst ethicists has (...) a different set of problems than the ones motivating virtue ethicists. Virtue epistemologists should mount a similar challenge to their contemporaries: instead of focusing on static states such as beliefs and evaluating whether or not they are justified, they should focus their efforts on evaluating and regulating the activities of inquiry and deliberation, and the role which virtues play in such evaluation and regulation.

Epistemology - the theory of knowledge and of justified belief - has always been of central importance in philosophy. Progress in other areas of philosophical research has often depended crucially on epistemological presuppositions. This Companion, with well over 250 articles ranging from summary discussions to major essays on topics of current controversy, is the first complete reference work devoted to the subject. All the main theoretical positions in epistemology are discussed and analysed, tougher with the different categories of knowledge itself (...) - scientific, historical, mathematical, a priori, moral and so on - and the special problems associated with these. There are also many entries covering individual concepts, arguments and problems, short definitions of technical terms, and biographical articles. With its unrivalled coverage of the field, supported by a comprehensive index and an extensive cross-referencing, the Companion is likely to remain the standard reference work in epistemology from undergraduate level upward for the foreseeable future.

fits our evidence.[1] I will propose some potential counter-examples to test this evidentialist thesis. My main intention in presenting the “counter-examples” is to better understand Feldman’s evidentialism, and evidentialism in general. How are we to understand what our evidence is, how it works, and how are we to understand the phrase “epistemically ought to believe” such that evidentialism might make sense as a plausible thesis in light of the examples? Of course, we may decide that there’s no such way to (...) understand evidentialism -- that it just isn’t a plausible thesis. I must admit that my suspicions lean in that direction. But the potential counter-examples are put forward, not in a refutational spirit (though I have nothing against good refutations in philosophy), but as an invitation to evidentialists and potential evidentialists to refine and/or explain their thesis in light of the at least apparent problems that the examples highlight.

Evidentialists maintain that epistemic justification is strictly a function of the evidence one has at the moment of belief. I argue here, on the basis of two kinds of cases, that the possession of good evidence is an insuflicient basis for justification. I go on to propose a modification of evidentialism according to which justification sometimes requires intellectually virtuous agency. The discussion thereby underscores an important point of contact between evidentialism and the more recent enterprise of virtue epistemology.

Abstract Do the central aims of epistemology, like those of moral philosophy, require that we designate some important place for those concepts located between the thin-normative and the non-normative? Put another way, does epistemology need "thick" evaluative concepts and with what do they contrast? There are inveterate traditions in analytic epistemology which, having legitimized a certain way of viewing the nature and scope of epistemology's subject matter, give this question a negative verdict; further, they have carried with them a tacit (...) commitment to what we argue to be an epistemic analogue of the reductionistic centralist thesis which Bernard Williams, in our view, successfully repudiates in ethics. In this essay, we challenge the epistemic analogue of the traditional but mistaken thesis. In offering an alternative to it which provides a comfortable home for the epistemic normativity which attends thick evaluative concepts, we align ourselves with what has been recently called the Value Turn in epistemology. From this perspective, we defend that, contrary to tradition, as influenced by centralist assumptions, epistemology does need thick evaluative concepts. Further, the sort of theories that will be able to give thick evaluative concepts an irreducible role in both belief and agent evaluation are adequately social epistemologies. What loosely refer to as second-wave of virtue epistemology is the widespread interest to provide a comfortable home for the role of thick normativity, as it is connected both with epistemic evaluation, and guidance. We recognize that, in breaking from centralism, there is a worry that a resulting anti-centralist theory will be reductionistic in the other direction, making the thick primary. We contend however that second-wave virtue epistemologies take different sources of social and epistemic value into account; they seek the 'right thickness' to ride with conception of epistemology and a field which due in part to virtue theory's resurgence, is today normative, diverse and expansive than was the traditional set of problems from which it emerged.

Evidentialism as Earl Conee and Richard Feldman present it is a philosophy with distinct aspects or sides: Evidentialism as a conceptual analysis of epistemic justification, and as a prescriptive ethics of belief. I argue that Conee and Feldman's ethics of belief has 'weak roots and sour fruits.' It has "weak roots" because it is premised on their account of epistemic justification qua synchronic rationality, and this is neither necessary nor sufficient for knowledge. Also, Conee and Feldman's thesis O2 (An agent (...) ought to always have just exactly that attitude towards a proposition supported by his / her evidence at that particular moment) is not support by in their “Ethics of Belief” article by V3 (Being synchronically rational at every moment is uniformly what it is to constitute epistemic success and to maximize epistemic value). That austere ethics of belief has "sour fruits" because the austere evidentialist ethic of belief is unable to support reasonable disagreement, and conflates psychographic contrareity epistemic fault or irrationality. The "hard line" and universal agnostic suspension it takes as the only rational stances of disagreement are really caricatures of different extreme responses to contrareity found among dogmatists and skeptics, respectively. I contrast this with John Rawls' understanding of "reasonable pluralism" and of the many sources of faultless disagreement over what Rawls termed comprehensive conceptions of the good. (shrink)

Epistemology has changed dramatically since Descartes, but many of the questions epistemologists address today are no different from the questions Descartes addressed. I begin by raising four sets of questions with which Descartes concerned himself, and explain briefly why Descartes regarded these sets of questions as interchangeable. My main purpose, however, is not historical. Rather, I wish to present an outline of a naturalistic approach to these questions. I will not defend naturalistic epistemology. Instead, I hope to explore what a (...) naturalistic approach to some traditional epistemological questions might look like; it is only through a better understanding of the consequences of naturalizing epistemology that we may hope properly to evaluate it. I will argue that questions which Descartes treated as interchangeable will have to be separated by naturalistically minded epistemologists. In the course of evaluating these questions from a naturalistic point of view, I hope to shed some light on the relation between reliability and justification, the dispute between internalist and externalist theories of justification, and the relation between ethics and epistemology.
