'Representation in Mind' is the first book in the new series 'Perspectives on Cognitive Science' and includes well known contributors in the areas of philosophy of mind, psychology and cognitive science. The papers in this volume offer new ideas, fresh approaches and new criticisms of old ideas. The papers deal in new ways with fundamental questions concerning the problem of mental representation that one contributor, Robert Cummins, has described as THE problem in philosophy of mind for some time now. The editors' introductory overview considers the problem for which mental representation has been seen as an answer, sketching an influential framework, outlining some of the issues addressed and then providing an overview of the papers. Issues include: the relation between mental representation and public, non-mental representation; misrepresentation; the role of mental representations in intelligent action; the relation between representation and consciousness; the relation between folk psychology and explanations invoking mental representations
