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.

Over the past two decades, Ray Jackendoff has persistently tackled difficult issues in the theory of mind and related theories of cognitive processing. Chief among his contributions is a formal theory that elaborates the nature of language and its relationship to a broad set of other domains. Languages of the Mind provides convenient access to Jackendoff's work over the past five years on the nature of mental representations in a variety of cognitive domains, in the context of a detailed theory of the level of conceptual structure developed in his earlier books Semantics and Cognition and Consciousness and the Computational Mind. The first two chapters summarize the theory of levels of mental representation ("languages of the mind") and their relationships to each other and show how conceptual structure can be approached along lines familiar from syntactic and phonological theory. From this background, subsequent chapters develop issues in word learning (and its pertinence to the Piaget-Chomsky debate) and the relation of conceptual structure to the understanding of physical space. Further chapters apply the theory to domains outside of traditional cognitive science. They include an approach to social and cultural cognition modeled on first principles of linguistic theory, the beginnings of a formal description of psychodynamic phenomena, and a discussion of musical parsing and its relation to musical affect that bears on current disputes in linguistic parsing. The final chapter takes up a long-standing conflict between philosophical and psychological approaches to the study of mind, arguing that mental representations should be regarded purely in terms of the combinatorial organization of brain states, and that the philosophical insistence on the intentionality of mental states should be abandoned.

'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

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.
