The Description for this book, The Analysis of Knowing: A Decade of Research, will be forthcoming.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

Jay Rosenberg offers a systematic philosophical theory of knowledge which is specifically responsive to the fact that we always engage the world from a particular perspective within it. It consequently calls into question in a fundamental way many received understandings regarding the relationships among the concepts of knowledge, belief, justification, and truth.

What is knowledge? How hard is it for a person to have knowledge? Good Knowledge, Bad Knowledge confronts contemporary philosophical attempts to answer those classic questions, offering a theory of knowledge that is unique in conceiving of knowledge in a non-absolutist way.

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

Knowledge in a Social World offers a philosophy for the information age. Alvin Goldman explores new frontiers by creating a thoroughgoing social epistemology, moving beyond the traditional focus on solitary knowers. Against the tides of postmodernism and social constructionism Goldman defends the integrity of truth and shows how to promote it by well-designed forms of social interaction. From science to education, from law to democracy, he shows why and how public institutions should seek knowledge-enhancing practices. The result is a bold, (...) timely, and systematic treatment of the philosophical foundations of an information society. (shrink)

Crispin Sartwell ingeniously defends the provocative thesis that mere true belief suffices for knowledge. In doing so, he challenges one of the most deeply entrenched epistemological tenets, namely that knowledge must be more than mere true belief. Particularly interesting is the way he defends his thesis by appealing to considerations adduced by such prominent epistemologists as William Alston, Laurence BonJour, Alvin Goldman and Paul Moser, each of whom denies that knowledge is merely true belief. In this paper, I argue that (...) the case Sartwell presents for his thesis fails. However, by examining why it fails, we may derive at least four important epistemological lessons: being justified does not entail being able to give a justification; we should distinguish between epistemic justification conceived of as intrinsically conducive to truth and conceived of as extrinsically conducive to truth; we should distinguish between epistemic justification conceived of as an essential criterion of knowledge and conceived of as an accidental criterion of knowledge ; and epistemologists need to specify how the telos of inquiry involves more than the acquisition of true beliefs.Socrates: Then tell me: what definition can we give with the least risk of contradicting ourselves?

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.

A wide-ranging study of the central concepts in epistemology - belief, truth and knowledge. Professor Armstrong offers a dispositional account of general beliefs and of knowledge of general propositions. Belief about particular matters of fact are described as structures in the mind of the believer which represent or 'map' reality, while general beliefs are dispositions to extend the 'map' or introduce casual relations between portions of the map according to general rules. 'Knowledge' denotes the reliability of such beliefs as representations (...) of reality. Within this framework Professor Armstrong offers a distinctive account of many of the main questions in general epistemology - the relations between beliefs and language, the notions of proposition, concept and idea, the analysis of truth, the varieties of knowledge, and the way in which beleifs and knowledge are supported by reasons. The book as a whole if offered as a contribution to a naturalistic account of man. (shrink)

The paper seeks a perfectly general argument regarding the non-contingent limits to any (human or non-human) knowledge. After expressing disappointment with the history of philosophy on this score, an argument is grounded in Fitch’s proof, which demonstrates the unknowability of some truths. The necessity of this unknowability is then defended by arguing for the necessity of Fitch’s premise—viz., there this is in fact some ignorance.

Wissen kann sich nicht in wahrer Meinung erschöpfen. Das ist ein in der Diskussion um ei- nen adäquaten Wissensbegriff fast einhellig akzeptierter Gemeinplatz. Der Grund dafür ist ein- fach und auf den ersten Blick einleuchtend. Unserem normalen Gebrauch des Wortes „Wissen“ zufolge würden wir von jemandem, der aufgrund bloßen Ratens zu der Überzeugung kommt, daß beim nächsten Spiel die Roulettekugel auf der Zahl 34 liegen bleibt, auch dann nicht sagen, er habe gewußt, daß es so kommen werde, wenn das Ergebnis (...) tatsächlich eintritt. Wir unter- scheiden zufällig wahre Überzeugungen von solchen, die nicht zufällig, sondern z.B. aufgrund sorgfältigen Überlegens zustandegekommen sind. Nur im zweiten Fall sprechen wir von Wis- sen; bloß zufällig wahre Überzeugungen haben keinen Anspruch auf diesen Ehrentitel. „Bloß zufällig wahr“ nennen wir Überzeugungen, die auf eine Weise zustande gekommen sind, die mit ihrer Wahrheit nichts zu tun hat: durch Raten, Vorahnungen, Überredung usw.

Often the first issue addressed by a theory of justified belief is the aim, goal, purpose, or objective of epistemic justification. What, in short, is the point of epistemic justification? Or, to put it a bit differently, why value justification: why is it worth having or pursuing? Prominent epistemologists, including both externalists and internalists, have proposed the following answer: the ultimate aim of epistemic justification is to maximize true belief and minimize false belief. This answer specifies what I’ll call the (...) “nominal aim,” an aim that gets endorsed by a number of well-known accounts of justification. William Alston, an externalist with certain internalist scruples, is among the most explicit champions of the nominal aim. (shrink)
