Five leading figures in the philosophy of mind and cognitive science debate the central topic of mental representation. Each author's contribution is specially written for this volume, and then collectively discussed by the others. The editor frames the discussions and provides a way into the debates for readers new to them.

The topic of this book is mental representation, a theoretical concept that lies at the core of cognitive science. Together with the idea that thinking is analogous to computational processing, this concept is responsible for the "cognitive turn" in the sciences of the mind and brain since the 1950s. Conceiving of cognitive processes (such as perception, reasoning, and motor control) as consisting of the manipulation of contentful vehicles that represent the world has led to tremendous empirical advancements in our explanations of behaviour. Perhaps the most famous discovery that explains behavior by appealing to the notion of mental representations was the discovery of 'place' cells that underlie spatial navigation and positioning, which earned researchers John O'Keefe, May-Britt Moser, and Edvard I. Moser a joint Nobel Prize in 2014. And yet, despite the empirical importance of the concept, there is no agreed definition or theoretical understanding of mental representation. This book constitutes a state-of-the-art overview on the topic of mental representation, assembling some of the leading experts in the field and allowing them to engage in meaningful exchanges over some of the most contentious questions. The collection gathers both proponents and critics of the notion, making room for debates dealing with the theoretical and ontological status of representations, the possibility of formulating a general account of mental representation which would fit our best explanatory practices, and the possibility of delivering such an account in fully naturalistic terms. Some contributors explore the relation between mutually incompatible notions of mental representation, stemming from the different disciplines composing the cognitive sciences (such as neuroscience, psychology, and computer science). Others question the ontological status and explanatory usefulness of the notion. And finally, some try to sketch a general theory of mental representations that could face the challenges outlined in the more critical chapters of the volume.

Our thoughts are meaningful. We think about things in the outside world; how can that be so? This is one of the deepest questions in contemporary philosophy. Ever since the 'cognitive revolution', states with meaning-mental representations-have been the key explanatory construct of the cognitive sciences. But there is still no widely accepted theory of how mental representations get their meaning. Powerful new methods in cognitive neuroscience can now reveal information processing in the brain in unprecedented detail. They show how the brain performs complex calculations on neural representations. Drawing on this cutting-edge research, Nicholas Shea uses a series of case studies from the cognitive sciences to develop a naturalistic account of the nature of mental representation. His approach is distinctive in focusing firmly on the 'subpersonal' representations that pervade so much of cognitive science. The diversity and depth of the case studies, illustrated by numerous figures, make this book unlike any previous treatment. It is important reading for philosophers of psychology and philosophers of mind, and of considerable interest to researchers throughout the cognitive sciences.

This volume is a collection of new and previously published essays focusing on one of the most exciting and actively discussed topics in contemporary philosophy: naturalistic theories of mental content. The volume brings together important papers written by some of the most distinguished theorists working in the field today. Authors contributing to the volume include Jerry Fodor, Rugh Millikan, Fred Dretske, Ned Block, Robert Cummins, and Daniel Dennett.

This collection of papers on issues in the theory of mental representation expresses a diversity of recent reflections on the idea that C. D. Broad so aptly characterized in the title of his book Mind and the World Order. An important impetus in the project of organizing this work were the discussions I had with Keith Lehrer while I was a Visiting Scholar in the department of Philosophy at the University of Arizona. His encouragement and friendship were of great value to me and I wish to express my thanks to him here. A word of thanks too for Mike Harnish who casually suggested the title Rerepresentation. I wish to express my thanks to Hans Schuurmans of the Computer Center at Tilburg University for his patient and cheerful assistance in preparing the manuscript. Professor J. Verster of the University of Groningen kindly provided the plates for the Ames Room figures. Thieu Kuys helped not only with the texts but also relieved me of chores so that I could devote more time to meeting deadlines. Barry Mildner had a major role in the text preparation using his skills and initiative in solving what seemed like endless technical problems. My deepest thanks are reserved for Anti Sax whose contribution to the project amount to a co-editorship of this volume. She participated in every phase of its development with valuable suggestions, prepared the indexes, and worked tirelessly to its completion.

conditions of the possibility of Experience ... must mean nothing else than all that which lies immanently in the essence of Experience ... and therefore belongs to it indispensably. The essence of Experience that phenomenological analysis of Experience elucidates is the same as the possibility of Experience, and all that which is determined in the essence, in the possibility of Experience, is eo ipso 1 condition of the possibility of Experience. Through acquaintance with Husserl's work, then, I developed my way of understand ing what, according to their very possibility, lies in conscious activities of mentally representing something, for example, by imagining or remembering it, or by viewing it in a picture, all these understood as forms of modified perception. As Husserl himself made clear, such reflective and descriptive analyses of the mental activities according to their very possibility are carried out regardless of the way they have actually come to be. However, I was also interested in developmen tal questions, especially with regard to the activity of imagining. Hence I turned to cognitive developmental psychology in order to get acquainted with the neces sary empirical material. Moreover, I conducted a pilot-study with young children that I had conceived according to phenomenologically relevant aspects concerning the difference and yet inner connection of the activities of imagining and viewing 2 pictures.

A fascinating exploration of the theories and arguments surrounding the notions of thought and representation. Now in its 2nd edition, Cranes's classic text has introduced thousands to some of the most important ideas in philosophy of mind.
