New essays on the philosophy of Ned Block, with substantive and wide-ranging responses by Block. Perhaps more than any other philosopher of mind, Ned Block synthesizes philosophical and scientific approaches to the mind; he is unique in moving back and forth across this divide, doing so with creativity and intensity. Over the course of his career, Block has made groundbreaking contributions to our understanding of intelligence, representation, and consciousness. Blockheads! (the title refers to Block's imaginary counterexample to the Turing test-and to the Block-enthusiast contributors) offers eighteen new essays on Block's work along with substantive and wide-ranging replies by Block. The essays and responses not only address Block's past contributions but are rich with new ideas and argument. They importantly clarify many key elements of Block's work, including his pessimism concerning such thought experiments as Commander Data and the Nation of China; his more general pessimism about intuitions and introspection in the philosophy of mind; the empirical case for an antifunctionalist, biological theory of phenomenal consciousness; the fading qualia problem for a biological theory; the link between phenomenal consciousness and representation (especially spatial representation); and the reducibility of phenomenal representation. Many of the contributors to Blockheads! are prominent philosophers themselves, including Tyler Burge, David Chalmers, Frank Jackson, and Hilary Putnam.

Philosopher Ned Block argues in this book that there is a "joint in nature" between perception and cognition and that by exploring the nature of that joint, one can solve mysteries of the mind. The first half of the book introduces a methodology for discovering what the fundamental differences are between cognition and perception and then applies that methodology to isolate how perception and cognition differ in format and content. The second half draws consequences for theories of consciousness, using results of the first half to argue against cognitive theories of consciousness that focus on prefrontal cortex. Along the way, Block tackles questions such as: Is perception conceptual and propositional? Is perception iconic or more akin to language in being discursive? What is the difference between the format and content of perception, and do perception and cognition have different formats? Is perception probabilistic, and if so, why are we not normally aware of this probabilistic nature of perception? Are the basic features of mind known as "core cognition" a third category in between perception and cognition? This book explores these questions not by appeals to "intuitions," as is common in philosophy, but to empirical evidence, including experiments in neuroscience and psychology.

This volume of Ned Block's writings collects his papers on consciousness, functionalism, and representationism. A number of these papers treat the significance of the multiple realizability of mental states for the mind-body problem -- a theme that has concerned Block since the 1960s. One paper on this topic considers the upshot for the mind-body problem of the possibility of a robot that is functionally like us but physically different -- as is Commander Data of "Star Trek's" second generation. The papers on consciousness treat such conceptual issues as phenomenal versus access consciousness, Dennett's theory of consciousness, and the function of consciousness, as well as such empirical matters as "How Not to Find the Neural Correlate of Consciousness," and (in an expanded version of a paper originally in "Trends in Cognitive Sciences") an argument that there are distinct neural correlates for access consciousness and phenomenal consciousness. Turning to the mind-body problem, Block defends physicalism against Max Black's argument concerning phenomenal modes of presentation. The papers on representationism consider "mental paint" as well as the "Inverted Earth" thought experiment -- a world in which colors are reversed but there is a compensating reversal in the words that are used to describe them.

"Consciousness, Function, and Representation," bringing together papers that have appeared primarily in journals and conference proceedings, can be regarded as Block's most complete statement of his positions on consciousness.

Intended for anyone attempting to find their way through the large and confusingly interwoven philosophical literature on consciousness, this reader brings together most of the principal texts in philosophy (and a small set of related key works in neuropsychology) on consciousness through 1997, and includes some forthcoming articles. Its extensive coverage strikes a balance between seminal works of the past few decades and the leading edge of philosophical research on consciousness.As no other anthology currently does, The Nature of Consciousness provides a substantial introduction to the field, and imposes structure on a vast and complicated literature, with sections covering stream of consciousness, theoretical issues, consciousness and representation, the function of consciousness, subjectivity and the explanatory gap, the knowledge argument, qualia, and monitoring conceptions of consciousness. Of the 49 contributions, 18 are either new or have been adapted from a previous publication.
