In his recent book, The Elm and the Expert, Fodor attempts to reconcile the computational model of human cognition with information‐theoretic semantics, the view that semantic, and mental, content consists of nothing more than causal or nomic relationships, between words and the world, or (roughly) brain states and the world. In this paper, we do not challenge the project. Nor do we show that Fodor has failed to carry it out. instead, we urge that his analysis, when made explicit, turns out rather differently than he thinks. In particular, in some places where he sees problems, he sometimes shows that there is no problem. And while he says two conceptions of information come to much the same thing, his analysis shows that they are very different. This is rather strange.

Kant made a number of highly original discoveries about the mind - about its ability to synthesise a single, coherent representation of self and world, about the unity it must have to do so, and about the mind's awareness of itself and the semantic apparatus it uses to achieve this awareness. The past fifty years have seen intense activity in research on human cognition. Even so, Kant's discoveries have not been superseded, and some of them have not even been assimilated into current thinking. That is particularly true of his work on unity and on the semantic apparatus of self-awareness. The first four chapters of this book present a comprehensive overview of Kant's model for non-specialists, an overview largely unencumbered by detailed exegesis. The work then offers a close study of five major discussions of the mind in the Critique of Pure Reason and Anthropology.

One of the many fault-lines within accounts of consciousness concerns the unity of consciousness. Some theorists claim that consciousness is unified—indeed, some theorists insist that consciousness is essentially unified. Other theorists assert that the unity of consciousness is an illusion, and that consciousness is often, if not invariably, disunified. Unfortunately, it is rare for proponents of either side of the debate to explain what the unity of consciousness might involve. What would it mean for consciousness to be unified? In this chapter I provide a brief cartography of the unity of consciousness. In the next section I introduce a number of unity relations that can hold between conscious states, and in the following sections I show how these unity relations can be used to construct various conceptions of the unity of consciousness—what I call unity theses. These unity theses provide us with a set of reference points by means of which we can orient discussions of the unity of consciousness.

Kant was a transcendental idealist even about the time‐order of representations. For Kant, idealism meant two things: We are aware only of the contents of our own mind and what we are aware of is largely a result of the activities of the mind. His constructivism is the central issue in this chapter. The first part of the chapter is devoted to demonstrating preliminary existence proof. The middle sections of the chapter take up the localization problem. The final section of the paper identifies and discusses an interesting tension in Kant. In the Refutation of Idealism, new to the second edition of Critique of Pure Reason, Kant espouses realism about time‐order of a kind that is difficult to reconcile with the idealism that he embraces elsewhere in the book.

In the Critique of Pure Reason (1781/7), Kant laid out a deep-running and largely original picture of the apperceptive mind, including a claim that in consciousness of self, one does not appear to oneself as an object and that consciousness of self is presupposed by consciousness of other things. As a result, consciousness of oneself does not provide knowledge of oneself and the referential apparatus of consciousness of self is radically different from other kinds of referential apparatus. The main purpose of this paper is to summarize this picture and then explore how much of it is still to be found in his late, unfinished Opus Postumum (1800/04).

Current views of consciousness can be divided by whether the theorist accepts or rejects cognitivism about consciousness. Cognitivism as we understand it is the view that consciousness is just a form of representation or an information-processing property of a system that has representations or perhaps both. Anti-cognitivists deny this, appealing to thought experiments about inverted spectra, zombies and the like to argue that consciousness could change while nothing cognitive or representational changes. Nearly everyone agrees, however, that consciousness has a _representational base._ Whether consciousness _simply is_ representational or cognitive, it at least _requires _representation (and cognition). In an ecumenical spirit, we will focus on this point of agreement and sketch a theory of what this representational base might be. We hope that the result will be a framework useful for investigating consciousness empirically.

Contemporary Philosophy in Focus will offer a series of introductory volumes to many of the dominant philosophical thinkers of the current age. Each volume will consist of newly commissioned essays that will cover all the major contributions of a preeminent philosopher in a systematic and accessible manner. Author of such groundbreaking and influential books as Consciousness Explained and Darwin's Dangerous Idea, Daniel C. Dennett has reached a huge general and professional audience that extends way beyond the confines of academic philosophy. He has made significant contributions to the study of consciousness, the development of the child's mind, cognitive ethnology, explanation in the social sciences, artificial intelligence, and evolutionary theory. This volume is the only truly introductory collection that traces these connections, explores the implications of Dennett's work, and furnishes the non-specialist with a fully-rounded account of why Dennett is such an important voice on the philosophical scene.

In the neglected 'Amphiboly of the Concepts of Reflection,' Kant introduces a new transcendental activity, Transcendental Deliberation. It aims to determine to which faculty a representation belongs and does so by examining the representation's relationships to other representations. This enterprise yields some powerful ideas. Some of the relationships studied have great interest, numerical identity in particular. Indeed, seeing Kant discuss it here, one wonders why he did not include it in the Table of Categories. Kant gives a solid argument for the necessity of a sensible element in representations, something not found elsewhere in the Transcendental Analytic.

Talk of levels is everywhere in cognitive science. Whether it is in terms of adjudicating longstanding debates or motivating foundational concepts, one cannot go far without hearing about the need to talk at different ‘levels’. Yet in spite of its widespread application and use, the concept of levels has received little sustained attention within cognitive science. This paper provides an analysis of the various ways the notion of levels has been deployed within cognitive science. The paper begins by introducing and motivating discussion via four representative accounts of levels. It then turns to outlining and relating the four accounts using two dimensions of comparison. The result is the creation of a conceptual framework that maps the logical space of levels talk, which offers an important step toward making sense of levels talk within cognitive science.

A movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods to illuminate issues in neuroscience began about twenty-five years ago. Results in neuroscience have affected how we see traditional areas of philosophical concern such as perception, belief-formation, and consciousness. There is an interesting interaction between some of the distinctive features of neuroscience and important general issues in the philosophy of science. And recent neuroscience has thrown up a few conceptual issues that philosophers are perhaps best trained to deal with. After sketching the history of the movement, we explore the relationships between neuroscience and philosophy and introduce some of the specific issues that have arisen.
