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 collects 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. 'Sosa is one of the most prominent and most important epistemologists on the current American scene.' William (...) P. Alston, Syracuse University. (shrink)

The influence of J. L. Austin on contemporary philosophy was substantial during his lifetime, and has grown greatly since his death, at the height of his powers, in 1960. Philosophical Papers, first published in 1961, was the first of three volumes of Austin's work to be edited by J. O. Urmson and G. J. Warnock. Together with Sense and Sensibilia and How to do things with Words, it has extended Austin's influence far beyond the circle who knew him or read (...) the handful of papers he published in journals.

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.

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

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.

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.

In the good old days, a large part of the debate about skepticism focused on the quality of the reasons we have for believing propositions of various types. Skeptics about knowledge in a given domain argued that our reasons for believing propositions in that domain were not good enough to give us knowledge; opponents of skepticism argued that they were. The different conclusions drawn by skeptics and non-skeptics could come either from differences in their views about the standards or conditions (...) we had to satisfy in order to have knowledge or from differences in their assessments of the quality or character of the reasons we have. In recent years, discussions of skepticism have often focused on three anti-skeptical responses that don't directly address the questions about reasons or evidence that used to be considered fundamental. These anti-skeptical responses are: 1) content externalism, as proposed by Hilary Putnam1; 2) the denial of closure, as proposed by Robert Nozick2; and 3) contextualism about knowledge attributions, as proposed by Stewart Cohen, Keith DeRose, and David Lewis3. I believe that these recent responses to skepticism characteristically avoid the central epistemological issues raised by skepticism and often concede to skeptics far more than is warranted. In this paper I will examine some contextualist responses to skepticism. In Section I I describe the general idea of contextualism and its application to skepticism. In Section II I describe and briefly discuss some particular versions of contextualism. In Section III I argue that even if it is true that sentences attributing knowledge have contextually variable truth conditions, this fact does not provide the basis for a satisfactory response to skepticism. This is because the central issue raised by skepticism is whether we satisfy the standards for knowledge in place in ordinary contexts, not whether we satisfy some allegedly higher standards which, according to contextualists, are in place in some epistemological contexts. In effect, this paper is part of an argument for a return to the good old days. (shrink)

This article surveys work in epistemology since the mid-1980s. It focuses on contextualism about knowledge attributions, modest forms of foundationalism, and the internalism/externalism debate and its connections to the ethics of belief.

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.

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)

In a recent, and influential, article, Crispin Wright maintains that a familiar form of scepticismwhich finds its core expression in Descartes’ dreaming argumentcan be defused (or, to use Wright’s own parlance, “imploded”), by showing how it employs self-defeating reasoning. I offer two fundamental reasons for rejecting Wright’s ‘implosion’ of scepticism. On the one hand, I argue that, even by Wright’s own lights, it is unclear whether there is a sceptical argument to implode in the first place. On the other, I (...) claim that even on the supposition that Wright has indeed succeeded in setting-up such an argument, he nevertheless fails to follow-through with an adequate response. A diagnosis of the failure of Wright’s approach is then given in the context of the wider sceptical debate. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Much has been written about epistemological skepticism in the last ten or so years, but there remain some unanswered questions concerning the structure of what has become the canonical Cartesian skeptical argument. In this paper, I would like to take a closer look at this structure in order to determine just which epistemic principles are required by the argument.

A great deal of discussion in the recent literature has been devoted to the so-called 'McKinsey' paradox which purports to show that semantic externalism is incompatible with the sort of authoritative knowledge that we take ourselves to have of our own thought contents. In this paper I examine one influential epistemological response to this paradox which is due to Crispin Wright and Martin Davies. I argue that it fails to meet the challenge posed by McKinsey but that, if it is (...) set within an externalist epistemology, it may have application to a related paradox that concerns the problem of radical scepticism.

This paper compares two kinds of epistemic principles---an underdetermination principle and a deductive closure principle. It argues that each principle provides the basis for an independently motivated skeptical argument. It examines the logical relations between the premises of the two kinds of skeptical argument and concludes that the deductive closure argument cannot be refuted without refuting the underdetermination argument. The underdetermination argument, however, can be refuted without refuting the deductive closure argument. In this respect, the deductive closure argument is the (...) stronger of the two. (shrink)

An intellectual virtue is a quality bound to help maximize one’s surplus of truth over error; or so let us assume for now, though a more just conception may include as desiderata also generality, coherence, and explanatory power, unless the value of these is itself explained as derivative from the character of their contribution precisely to one’s surplus of truth over error. This last is an issue I mention in order to lay it aside. Here we assume only a teleological (...) conception of intellectual virtue, the relevant end being a proper relation to the truth, exact requirements of such propriety not here fully specified.

One of the most important developments in the theory of knowledge during the past two decades has been a shift in emphasis to concern with issues of the reliability of various processes of belief formation. One way of arriving at beliefs is more reliable than another in a specified set of circumstances just insofar as it is more likely, in those circumstances, to produce a true belief. Classical epistemology, taking its cue from Plato, understood knowledge as justified true belief. While (...) Gettier had raised questions about the joint sufficiency of those three conditions, it is only more recently that their individual necessity was seriously questioned. What I will call the "Founding Insight" of reliabilist epistemologies is the claim that true beliefs can, at least in some cases, amount to genuine knowledge even where the justification condition is not met (in the sense that the candidate knower is unable to produce suitable justifications), provided the beliefs resulted from the exercise of capacities that are reliable producers of true beliefs in the circumstances in which they were in fact exercised.

In “Contextualism and Knowledge Attributions,” I argue that advocates of the “Relevant Alternatives” theory of knowledge fall into certain mistakes result if they tie the content of a knowledge attribution, on a given occasion of use, too tightly to what the range of relevant alternatives is on that occasion, and I sketch an alternative approach to the issues involved that avoids such mistakes. In “The Shifting Content of Knowledge Attributions,” Anthony Brueckner charges that my own account of these matters falls (...) to an objection of his. But Brueckner is wrong about this, as I’ll here argue. (shrink)

Traditionally, skeptics as well as their opponents have agreed that in order to know that p one must be able, by some preferred means, to rule out all the alternatives to p. Recently, however, some philosophers have attempted to avert skepticism not (merely) by weakening the preferred means but rather by articulating a subset of the alternatives to p — the so-called relevant alternatives — and insisting that knowledge that p requires only that we be able (by the preferred means) (...) to rule out members of the set. In this paper I argue that a precise formulation of this new approach reveals it inadequate as a solution to skepticism. (shrink)

In Unnatural Doubts, Michael Williams constructs a masterly polemic against the very idea of epistemology, as traditionally conceived.

In this paper I defend a relevant possibilities approach against a familiar kind of skepticism, and I argue that virtue epistemology can provide a theoretical grounding for the kind of solutions that is offered. In the section that follows I outline both the skeptical problems and the solution. In the remaining sections I develop the proposal in more detail. If my argument is sound then the paper also constitutes an argument in favor of virtue epistemology.
