Knowledge and Lotteries is organized around an epistemological puzzle: in many cases, we seem consistently inclined to deny that we know a certain class of propositions, while crediting ourselves with knowledge of propositions that imply them. In its starkest form, the puzzle is this: we do not think we know that a given lottery ticket will be a loser, yet we normally count ourselves as knowing all sorts of ordinary things that entail that its holder will not suddenly acquire a (...) large fortune. After providing a number of specific and general characterizations of the puzzle, Hawthorne carefully examines the competing merits of candidate solutions. In so doing, he explores a number of central questions concerning the nature and importance of knowledge, including the relationship of knowledge to assertion and practical reasoning, the status of epistemic closure principles, the merits of various brands of scepticism, the prospects for a contextualist account of knowledge, and the potential for other sorts of salience-sensitive accounts. Along the way, he offers a careful treatment of pertinent issues at the foundations of semantics. His book will be of interest to anyone working in the field of epistemology, as well as to philosophers of language. (shrink)

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a (...) number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (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.

In Contradiction advocates and defends the view that there are true contradictions, a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in 1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author’s reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the companion (...) volume, Doubt Truth to be a Liar, also published by Oxford University Press in 2006. (shrink)

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

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.

Rich with historical and cultural value, these works are published unaltered from the original University of Minnesota Press editions.

_Epistemology_ is an accessible and indispensable volume for undergraduates studying philosophy. Essential introduction to epistemology, a field of fundamental philosophical importance Offers concise and well-written synopses of different epistemological debates and concerns.

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.

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 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)

Paradoxes are more than just intellectual puzzles - they raise substantive philosophical issues and offer the promise of increased philosophical knowledge. In this introduction to paradox and paradoxes, Doris Olin shows how seductive paradoxes can be, why they confuse and confound, and why they continue to fascinate. Olin examines the nature of paradox, outlining a rigorous definition and providing a clear and incisive statement of what does and does not count as a resolution of a paradox. The view that a (...) statement can be both true and false, that contradictions can be true, is seen to provide a challenge to the account of paradox resolution, and is explored. With this framework in place, the book then turns to an in-depth treatment of the Prediction Paradox, versions of the Preface/Fallibility Paradox, the Lottery Paradox, Newcomb's Problem, the Prisoner's Dilemma and the Sorites Paradox. Each of these paradoxes is shown to have considerable philosophical punch. Olin unpacks the central arguments in a clear and systematic fashion, offers original analyses and solutions, and exposes further unsettling implications for some of our most deep-seated principles and convictions.

Despite various attempts to rectify matters, the internalism-externalism (I-E) debate in epistemology remains mired in serious confusion. I present a new account of this debate, one which fits well with entrenched views on the I-E distinction and illuminates the fundamental disagreements at the heart of the debate. Roughly speaking, the I-E debate is over whether or not certain of the necessary conditions of positive epistemic status are internal. But what is the sense of internal here? And of which conditions of (...) which positive epistemic status are we speaking? I argue that an adequate answer to these questions requires reference to what I call the no-defeater condition which is satisfied by a subjects belief B just in case she does not believe that B is defeated. I close by stating succinctly the main positions taken in the I-E debate, identifying the basic points of disagreement and suggesting fruitful courses for future discussion. (shrink)

On the basis of arguments showing that none of the most influential analyses of Moore’s paradox yields a successful resolution of the problem, a new analysis of it is offered. It is argued that, in attempting to render verdicts of either inconsistency or self-contradiction or self-refutation, those analyses have all failed to satisfactorily explain why a Moore-paradoxical proposition is such that it cannot be rationally believed. According to the proposed solution put forward here, a Moore-paradoxical proposition is one for which (...) the believer can have no non-overridden evidence. The arguments for this claim make use of some of Peter Klein’s views on epistemic defeasibility. It is further suggested that this proposal may have important meta-epistemological implications.

Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories (...) of knowledge. (shrink)

Este artigo examina a objeção ao fechamento [dedutivo] que surge no contexto de certos paradoxos epistêmicos, paradoxos cuja conclusão é que a crença justificada pode ser inconsistente. É universalmente aceito que, se essa conclusão é correta, o fechamento deve ser rejeitado, para que se evite a crença justificada em enunciados contraditórios (P, ~P). Mas, mesmo que os argumentos desses paradoxos – o paradoxo da falibilidade (do prefácio) e o paradoxo da loteria – sejam mal-sucedidos, eles, ainda assim, sugerem a existência (...) de evidência independente para uma objeção mais direta contra o fechamento. O exame do argumento da falibilidade revela uma exigência de modéstia epistêmica que viola o fechamento a partir de múltiplas premissas. A reflexão sobre o paradoxo da loteria nos confronta com um dilema em que cada alternativa fornece um contra-exemplo ao fechamento a partir de uma única premissa. Seja ou não possível a inconsistência racional, há uma objeção contra o fechamento. PALAVRAS-CHAVE – Fechamento dedutivo. Falibilidade. Paradoxo da Loteria. Paradoxo do Prefácio. Justificação. Inconsistência. ABSTRACT This paper examines the case against closure that arises in the context of certain epistemic paradoxes, paradoxes whose conclusion is that it is possible for justified belief to be inconsistent. It is generally agreed that if this conclusion is correct, closure must be rejected in order to avoid justified belief in contradictory statements (P, ~P). But even if the arguments of these paradoxes – the fallibility (preface) paradox and the lottery paradox – are unsuccessful, they nonetheless suggest independent grounds for a more direct case against closure. Examination of the fallibility argument reveals a requirement of epistemic modesty that violates multiple premise closure. Reflection on the lottery paradox presents us with a dilemma in which each alternative provides a counterexample to single premise closure. Whether or not rational inconsistency is possible, there is a case against closure. KEY WORDS – Closure. Fallibility. Lottery paradox. Preface paradox. Justification. Inconsistency. (shrink)
