Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge. Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate. Introduces students to fundamental questions within epistemology while (...) engaging in contemporary debates. Written by two of today’s foremost epistemologists. Includes an extensive bibliography.

One of the many problems that would have t o be solved by a satisfactory theory of empirical knowledge, perhaps the most central is a general structural problem which I shall call the epistemic regress problem: the problem of how to avoid an in- finite and presumably vicious regress of justification in ones account of the justifica- tion of empirical beliefs. Foundationalist theories of empirical knowledge, as we shall see further below, attempt t o avoid the regress by locating a (...) class of empirical beliefs whose justification does not depend on that of other empirical beliefs. Extemalist theories, the topic of the present paper, represent one species of foundationalism. (shrink)

This paper offers and analysis of Ernest Sosa's Virtue Perspectivism. Although Sosa has been credited with fathering the influential contemporary movement known as Virtue Epistemology, I argue that Sosa imprudently abandons the reliabilist-based insights of Virtue Epistemology in favor of a reflection-based, "perspectival"' view. Sosa's mixed allegiance to reliabilist-based and reflection-based views of knowledge, in fact, leads to an unwelcome tension in his thought which can be relieved by recognizing that his reflection-based view is in fact an account of the (...) cognitive state of understanding, rather than an account of knowledge. Sosa makes matters difficult for himself because he expects too much, as it were, from the concept of knowledge, and in the process burdens his view with elements of reflection it does not require. To solve the problem, I suggest that Sosa needs to develop a two-tiered epistemology which recognizes that knowledge, on the one hand, and understanding, on the other, both have necessary and sufficient conditions unique to themselves.

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.
