Almost everyone believes that testimony can transmit knowledge from speaker to hearer. What some philosophers mean by this is ordinary and pedestrian-- they mean only that, in at least some cases, a speaker S knows that p, S testifies that p to a hearer H, and H comes to know that p as a result of believing S's testimony. There is disagreement about how this occurs, but that it does occur is sufficient for the transmission of knowledge in the intended sense. On this understanding of transmission, the natural questions are these: (1) What conditions, in addition to speaker knowledge and speaker testimony, are sufficient for the hearer to gain testimonial knowledge?; and (2) Is speaker knowledge always necessary for testimonial knowledge? That is: Is all testimonial knowledge transmitted knowledge?

Alvin Plantinga charges classical foundationalism with self-referential incoherence, meaning that that doctrine employs criteria for rationally acceptable propositions which exclude the criteria themselves. More specifically, the charge is that the criteria are neither properly basic nor supported by properly basic propositions. In section 1 the doctrine of classical foundationalism is briefly explained. In section 2, a defense against Plantinga's objection is provided showing how the foundationalist can provide arguments which ground the criteria in question in properly basic propositions.

Moore's 'Proof of an External World' has evoked a variety of responses from philosophers, including bafflement, indignation and sympathetic reconstruction. I argue that Moore should be understood as following Thomas Reid on a variety of points, both epistemological and methodological. Moreover, Moore and Reid are exactly right on all of these points. Hence what I present is a defence of Moore's 'Proof', as well as an interpretation. Finally, I argue that the Reid-Moore position is useful for resolving an issue that has recently received attention in epistemology, namely, how is it that one knows that one is not a brain in a vat?

Virtue epistemology is a diverse and flourishing field, one of the most exciting developments in epistemology to emerge over the last three decades. Virtue epistemology begins with the premise that epistemology is a normative discipline and, accordingly, a central task of epistemology is to explain the sort of normativity that knowledge, justified belief, and the like involve. A second premise is that a focus on the intellectual virtues (individual intellectual excellences) is essential to carrying out this central task. This collection offers some of the most influential and agenda-setting work at the heart of virtue epistemology's research program. Taken together, they will equip the reader to enter the ongoing discussion and debate in the field. The selections range from seminal contributions by Ernest Sosa, who introduced the notion of intellectual virtue into the contemporary literature, to a study of "epistemic justice" that draws on _To Kill a Mockingbird_ and The Talented Mr. Ripley. The readings include overviews of the field that also serve to advance the discussion; investigations of the nature of knowledge; reflections on the value of knowledge; examinations of credit and luck; and explorations of future directions for research. The hardcover edition does not include a dust jacket.

Sosa's work on epistemic circularity has significance beyond his own brand of virtue epistemology, with its characteristic distinction between animal and reflective knowledge. On the contrary, it demonstrates the necessity of embracing foundationalism and externalism in epistemology, while at the same time answering various charges (some perennial) against epistemology in general. This paper distinguishes six kinds of epistemic circularity that are discussed in Sosa's work: two virtuous, two vicious, and two benign. This framework is used to reconstruct Sosa's responses to various problems involving charges of epistemic circularity. In particular, we look at Sosa's response to e Problem of the Criterion.

In the history of philosophical thought, few themes loom as large as skepticism. Skepticism has been the most visible and important part of debates about knowledge. Skepticism at its most basic questions our cognitive achievements, challenges our ability to obtain reliable knowledge; casting doubt on our attempts to seek and understand the truth about everything from ethics, to other minds, religious belief, and even the underlying structure of matter and reality. Since Descartes, the defense of knowledge against skepticism has been one of the primary tasks not just of epistemology but philosophy itself. The Oxford Handbook of Skepticism features twenty-six newly commissioned chapters by top figures in the field. Part One contains articles explaining important kinds of skeptical reasoning. Part Two focuses on responses to skeptical arguments. Part Three concentrates on important contemporary issues revolving around skepticism. As the first volume of its kind, the articles make significant contributions to the debate on skepticism
