In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

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)

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)

Justification, or at least ‘justification’, bulks large in recent epistemology. The view that knowledge consists of true-justified-belief has been prominent in this century, and the justification of belief has attracted considerable attention in its own right. But it is usually not at all clear just what an epistemologist means by ‘justified’, just what concept the term is used to express. An enormous amount of energy has gone into the attempt to specify conditions under which beliefs of one or another sort (...) are justified; but relatively little has been done to explain what it is for a belief to be justified, what that is for which conditions are being sought. The most common procedure has been to proceed on the basis of a number of obvious cases of justified belief, without pausing to determine what property it is of which these cases are instances. Now even if there were some single determinate concept that all these theoriests have implicitly in mind, this procedure would be less than wholly satisfactory. For in the absence of an explicit account of the concept being applied, we lack the most fundamental basis for deciding between supposed intuitions and for evaluating proposed conditions of justification. And in any event, as philosophers we do not seek merely to speak the truth, but also to gain an explicit, reflective understanding of the matters with which we deal. We want to know not only when our beliefs are justified, but also what it is to enjoy that status. True, not every fundamental concept can be explicated, but we shall find that much can be done with this one. (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.

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.
