Epistemology, or "the theory of knowledge," is concerned with how we know what we know, what justifies us in believing what we believe, and what standards of evidence we should use in seeking truths about the world and human experience. This comprehensive introduction to the field of epistemology explains the concepts and theories central to understanding knowledge. Along with covering the traditional topics of the discipline in detail, Epistemology explores emerging areas of research. The third edition features new sections on such topics as the nature of intuition, the skeptical challenge of rational disagreement, and "the value problem" - the range of questions concerning why knowledge and justified true belief have value beyond that of merely true belief. Updated and expanded, Epistemology remains a superb introduction to one of the most fundamental fields of philosophy.
