This is a new and revised version of a much–acclaimed text designed to be used on introductory courses in epistemology. It covers both historically important topics and current issues and debates, and by assuming little or no philosophical knowledge or sophistication, it guides the beginning student through the main landmarks of epistemology. The new edition includes thoroughly revised chapters on mainstream topics such as beliefs and perception, induction and probability, and knowledge of minds. It also provides new and engaging coverage of topics such as naturalistic epistemology, Bayesian epistemology, externalism and moral knowledge, that have come to prominence since publication of the first edition. Helpful new pedagogical features at the end of each chapter are the comprehension questions, that test the student's understanding of the information, and the simulation questions, that challenge the student and invite deeper reflection.
