The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (shrink)

What modal relation must a fact bear to a belief in order for this belief to constitute knowledge of that fact? Externalists have proposed various answers, including some that combine externalism with contextualism. We shall find that various forms of externalism share a modal conception of “sensitivity” open to serious objections. Fortunately, the undeniable intuitive attractiveness of this conception can be explained through an easily confused but far preferable notion of “safety.” The denouement of our reflections, finally, will be to (...) show how replacing sensitivity with safety makes it possible to defend plain Moorean common sense against the spurious advantages over it claimed by skeptical, tracking, relevant-alternative, and contextualist accounts.

The recent movement towards virtue–theoretic treatments of epistemological concepts can be understood in terms of the desire to eliminate epistemic luck. Significantly, however, it is argued that the two main varieties of virtue epistemology are responding to different types of epistemic luck. In particular, whilst proponents of reliabilism–based virtue theories have been focusing on the problem of what I call “veritic” epistemic luck, non–reliabilism–based virtue theories have instead been concerned with a very different type of epistemic luck, what I call (...) “reflective” epistemic luck. It is argued that, prima facie at least, both forms of epistemic luck need to be responded to by any adequate epistemological theory. The problem, however, is that one can best eliminate veritic epistemic luck by adducing a so–called safety–based epistemological theory that need not be allied to a virtue–based account, and there is no fully adequate way of eliminating reflective epistemic luck. I thus conclude that this raises a fundamental difficulty for virtue–based epistemological theories, on either construal. [ABSTRACT FROM AUTHOR]. (shrink)

A certain interpretation of Wittgenstein’s remarks in On Certaintyadvanced by such figures as Hilary Putnam, Peter Strawson, Avrum Stroll and Crispin Wrighthas become common currency in the recent literature. In particular, this reading focuses upon the supposed anti-sceptical import of the Wittgensteinian notion of a “hinge” proposition. In this paper it is argued that this interpretation is flawed both on the grounds that there is insufficient textual support for this reading and that, in any case, it leads to unpalatable philosophical (...) problems. Moreover, it is claimed that the popularity of this construal of On Certainty in the contemporary debate reflects an implicit commitment to the contentious doctrine of epistemological internalism. Nevertheless, it is argued that, suitably modified along the epistemologically externalist lines suggested by Michael Williams, one might be able to resurrect a viable anti-sceptical hinge proposition thesis. Furthermore, it is claimed that such a conception of the notion also receives some, albeit inconclusive, textual support from On Certainty. (shrink)

G. E. Moore famously offered a strikingly straightforward response to the radical sceptic which simply consisted of the claim that one could know, on the basis of one's knowledge that one has hands, that there exists an external world. In general, the Moorean response to scepticism maintains that we can know the denials of sceptical hypotheses on the basis of our knowledge of everyday propositions. In the recent literature two proposals have been put forward to try to accommodate, to varying (...) extents, this Moorean thesis. On the one hand, there are those who endorse an externalist version of contextualism, such as Keith DeRose, who have claimed that there must be some contexts in which Moore is right. More radically still, Ernest Sosa has expanded on this externalist thesis by arguing that, contra DeRose's contextualism, Moore may be right in all contexts. In this paper I evaluate these claims and argue that, suitably modified, one can resurrect the main elements of the Moorean anti-sceptical thesis. (shrink)

One of the key supposed 'platitudes' of contemporary epistemology is the claim that knowledge excludes luck. One can see the attraction of such a claim, in that knowledge is something that one can take credit for - it is an achievement of sorts - and yet luck undermines genuine achievement. The problem, however, is that luck seems to be an all-pervasive feature of our epistemic enterprises, which tempts us to think that either scepticism is true and that we don't know (...) very much, or else that luck is compatible with knowledge after all. In this book, Duncan Pritchard argues that we do not need to choose between these two austere alternatives, since a closer examination of what is involved in the notion of epistemic luck reveals varieties of luck that are compatible with knowledge possession and varieties that aren't. Moreover, Pritchard shows that a more nuanced understanding of the relationship between luck and knowledge can cast light on many of the most central topics in contemporary epistemology. These topics include: the externalism/internalism distinction; virtue epistemology; the problem of scepticism; metaepistemological scepticism; modal epistemology; and the problem of moral luck. All epistemologists will need to come to terms with Pritchard's original and incisive contribution. (shrink)

Perhaps the most dominant anti‐sceptical proposal in recent literature –advanced by such figures as Stewart Cohen, Keith DeRose and David Lewis –is the contextualist response to radical scepticism. Central to the contextualist thesis is the claim that, unlike other non‐contextualist anti‐sceptical theories, contextualism offers a dissolution of the sceptical paradox that respects our common sense epistemological intuitions. Taking DeRose's view as representative of the contextualist position, it is argued that instead of offering us an intuitive response to scepticism, contextualism is (...) actually committed to a revisionist stance as regards our everyday usage of epistemic terms. In particular, it is argued that the thesis fails to present a satisfactory explication of a notion –that of‘epistemic descent’– that is pivotal to the anti‐sceptical import of the account. On the positive side, however, it is claimed that although the contextualist response to scepticism is ultimately unsatisfying, DeRose's theory does contain within it the framework for a completely different ‐ and far more persuasive ‐ account of the‘phenomenology’of scepticism which runs along non‐contextualist lines.

This essay defends virtue reliabilism against a line of argument put forward by Duncan Pritchard. In the process, it discusses (1) the motivations for virtue reliabilism, (2) some analogies between epistemic virtue and moral virtue, and (3) the relation between virtue (epistemic and otherwise) and luck (epistemic and otherwise). It argues that considerations about virtue and luck suggest a solution to Gettier problems from the perspective of a virtue theory.

The second major thesis of the book follows closely on the first: that the analysis of skeptical arguments is philosophically useful and important, and should therefore have a central role in the methodology of philosophy, and especially in the methodology of epistemology. A close analysis of skeptical arguments highlights our pre-theoretically plausible, but ultimately mistaken, assumptions about the nature of knowledge and evidence. Skeptical arguments are powerful just because their assumptions are so plausible pre-theoretically. But the arguments show us where (...) those assumptions lead, and thereby force us to rethink those assumptions. On this view, skeptical arguments constitute theoretical problems rather than practical problems. There is no “practical” or “existential” problem of skepticism. Rather, skeptical arguments show us that we need to rethink our assumptions about knowledge and evidence, and replace them with something better. (shrink)

Against the traditional view, Alvin Goldman argues that logic, probability theory, and linguistic analysis cannot by themselves delineate principles of rationality or justified belief. The mind's operations must be taken into account.

This paper presents a partial analysis of perceptual knowledge, an analysis that will, I hope, lay a foundation for a general theory of knowing. Like an earlier theory I proposed, the envisaged theory would seek to explicate the concept of knowledge by reference to the causal processes that produce (or sustain) belief. Unlike the earlier theory, however, it would abandon the requirement that a knower's belief that p be causally connected with the fact, or state of affairs, that p.

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

From the back cover: "Ever since Plato, philosophers have faced one central question: What is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa has collected his essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge, externalism versus internalism, foundationalism versus coherentism, and the problem of the criterion. The resulting book is a valuable resource for scholars and can (...) serve as a textbook for graduate seminars in epistemology.". (shrink)

Almost all theories of knowledge and justified belief employ moral concepts and forms of argument borrowed from moral theories, but none of them pay attention to the current renaissance in virtue ethics. This remarkable book is the first attempt to establish a theory of knowledge based on the model of virtue theory in ethics. The book develops the concept of an intellectual virtue, and then shows how the concept can be used to give an account of the major concepts in (...) epistemology, including the concept of knowledge. This highly original work of philosophy for professionals will also provide students with an excellent introduction to epistemology, virtue theory, and the relationship between ethics and epistemology.

This book, first published in 2000, is about the nature of skeptical arguments and their role in philosophical inquiry. John Greco delineates three main theses: that a number of historically prominent skeptical arguments make no obvious mistake, and therefore cannot be easily dismissed; that the analysis of skeptical arguments is philosophically useful and important, and should therefore have a central place in the methodology of philosophy; and that taking skeptical arguments seriously requires us to adopt an externalist, reliabilist epistemology. Greco (...) argues that the importance of skeptical arguments is methodological. It is further argued that taking skeptical arguments seriously requires us to adopt a version of 'virtue epistemology', or a theory of knowledge that makes intellectual virtue central in the analysis of knowledge. The above methodology has consequences for moral and religious epistemology; in particular, a theory of moral perception is defended. (shrink)

There are three primary aims of the book. The first, set out in the book's introduction, is to explain how two fairly recent developments in philosophy, externalism and modalism, provide the basis for a promising account of knowledge - an account that achieves anti-skeptical results and avoids Gettier-style counterexamples that are based on an agent having warranted beliefs that are merely luckily true. Epistemological externalism is the thesis that not all the factors that make a true belief a case of (...) knowledge need to be cognitively accessible or "internal" to the agent. Modalism, as the author construes it, is the use of possible worlds talk in clarifying what would or might be the case and what is necessarily so." "The second objective is to work through the different modalized epistemologies extant in the literature, assessing their strengths and weaknesses, with a view toward constructing a working theory. Finally, the author proposes the theory that knowledge is reliably formed, sensitive true belief, and defends the theory against objections."--Jacket. (shrink)

This discussion surveys recent developments in the treatment of the epistemological problem of skepticism. These are arguments which attack our knowledge of certain truths rather than, say, our belief in the existence of certain entities. In particular, this article focuses on the radical versions of these skeptical arguments, arguments which purport to show that knowledge is, for the most part, impossible, rather than just that we lack knowledge in a particular discourse. Although most of the key recent developments in this (...) area have taken place since the late 1980s and early 1990s, it is necessary to also discuss some of the movements that have developed since 1970 in order to give these recent developments the necessary setting. The date of 1970 is dictated by the publication in that year of Fred Dretske’s seminal article “Epistemic Operators,” which both pushed a “relevant alternatives” theory of knowledge to the fore of discussion and also brought into focus one possible line of argument against the so-called “closure” principle for knowledge. In so doing, it provided one of the main sources of response to the emergent.. (shrink)
