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.

The purpose of this paper is to explain how infinitism—the view that reasons are endless and non-repeating—solves the epistemic regress problem and to defend that solution against some objections. The first step is to explain what the epistemic regress problem is and, equally important, what it is not. Second, I will discuss the foundationalist and coherentist responses to the regress problem and offer some reasons for thinking that neither response can solve the problem, no matter how they are tweaked. Then, (...) I want to present the infinitist solution to the problem and defend it against some of the well known objections to it. (shrink)

One thing all forms of foundationalism have in common is that they hold that a belief can be justified noninferentially--i.e., that its justification need not depend on its being inferred from some other justified (or unjustified) belief. In some recent publications, Peter Klein argues that in virtue of having this feature, all forms of foundationalism are infected with an unacceptable arbitrariness that makes it irrational to be a practicing foundationalist. In this paper, I will explain why his objections to foundationalism (...) fail. (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.

David Annis is professor of philosophy at Ball State University. In this essay, Annis offers an alternative to the foundationalist-coherent controversy: "contextualism." This theory rejects both the idea of intrinsically basic beliefs in the foundational sense and the thesis that coherence is sufficient for justification. he argues that justification is relative to the varying norms of social practices.
