Providing an illuminating and informed introduction to central philosophical issues, concepts and perspectives in the core fields of metaphysics, epistemology and philosophical logic, the Dictionary takes the most common terms and notions and clarifies what they mean to the philosopher and what sort of problems the philosopher finds associated with them.Thoroughly revised and updated, the bibliographies supply core reading lists, and each entry uses extensive cross referencing to related themes and concepts to provide a greater sense of access, control and comprehension.The Dictionary will also provide those working in proximate fields with an understanding of areas of overlapping interest, concepts of common applicability and the full range and diversity of philosophical analysis and insight.
