Abstract

In seinem Klassiker erläutert der international führende Mathematiker und Physiker, Sir Roger Penrose, seine These, dass die geistigen Fähigkeiten des menschlichen Gehirns nicht durch Berechnungen von Elektronengehirnen erreicht werden können - und provozierte eine neue KI-Debatte. . . . des Kaisers neue Kleider - steht auf dem Buchumschlag. Der renommierte englische Physiker Penrose will damit sichtbar machen, daß die Vertreter der Künstlichen Intelligenz (KI) nackt dastehen. Mit einem 400 Seiten langen Exkurs versucht er, ihre Behauptung zu widerlegen, daß Maschinen ebenso intelligent sein können wie Menschen. bild der wissenschaft Roger Penrose ( . . . ) gelang das Kunststück, mit dem formelgespickten Wälzer "The Emperors's New Mind" (auf deutsch jetzt unter dem geistlosen Titel "Computerdenken" erschienen) auf den US-Bestsellerlisten zu landen, ungeachtet aller Quanten-Ket-Vektoren und Einsteinscher Krüümungstensoren, mit denen der Autor seine Leser plagt. DER SPIEGEL Das erklärte Ziel dieses Buches ist, den Standpunkt einiger KI-Enthusiasten zu widerlegen, daß Computer irgendwann all das können, was menschliche Gehirne können - und sogar mehr. Aber der Leser merkt bald, dass Pnerose vor allem das Ziel verfolgt, einen Wegzur großen Synthese von klassischer Physik, Quantenphysik und Neurowissenschaften aufzuzeigen. John Horgan in Scientific American Wer "Computerdenken" liest (oder durcharbeitet), sollte nicht auf Antwort hoffen, darf aber neue Sichtwiesen und überraschende Interpretationen erwarten. Ein nahrhaftes Geschenk für naturwissenschaftlich Interessierte. Die Zeit Trotz des mathematichen Themas wurde The Emperor's New Mind prompt ein Bestseller und sein Autor zum bestgehaßten Mann der KI-Szene ( . . . ).

Abstract

What is consciousness? How do physical processes in the brain give rise to the self-aware mind and to feelings as profoundly varied as love or hate, aesthetic pleasure or spiritual yearning? These questions today are among the most hotly debated issues among scientists and philosophers, and we have seen in recent years superb volumes by such eminent figures as Francis Crick, Daniel C. Dennett, Gerald Edelman, and Roger Penrose, all firing volleys in what has come to be called the consciousness wars. Now, in The Conscious Mind, philosopher David J. Chalmers offers a cogent analysis of this heated debate as he unveils a major new theory of consciousness, one that rejects the prevailing reductionist trend of science, while offering provocative insights into the relationship between mind and brain. Writing in a rigorous, thought-provoking style, the author takes us on a far-reaching tour through the philosophical ramifications of consciousness. Chalmers convincingly reveals how contemporary cognitive science and neurobiology have failed to explain how and why mental events emerge from physiological occurrences in the brain. He proposes instead that conscious experience must be understood in an entirely new light--as an irreducible entity (similar to such physical properties as time, mass, and space) that exists at a fundamental level and cannot be understood as the sum of its parts. And after suggesting some intriguing possibilities about the structure and laws of conscious experience, he details how his unique reinterpretation of the mind could be the focus of a new science. Throughout the book, Chalmers provides fascinating thought experiments that trenchantly illustrate his ideas. For example, in exploring the notion that consciousness could be experienced by machines as well as humans, Chalmers asks us to imagine a thinking brain in which neurons are slowly replaced by silicon chips that precisely duplicate their functions--as the neurons are replaced, will consciousness gradually fade away? The book also features thoughtful discussions of how the author's theories might be practically applied to subjects as diverse as artificial intelligence and the interpretation of quantum mechanics.
