Synopsis

Shadows of the mind is a profound exploration of what modern physics has to tell us about the mind, and a visionary description of what a new physics - one that is adequate to account for our extraordinary brain - might look like it is also a bold speculation on the biological process that makes consciousness what it is in this illuminating book penrose provides powerful arguments to support his conclusion that there is something in the conscious activity of the brain that transcends computation - and will find no explanation in terms of present-day science

About the Author

About the Author:
Roger Penrose is the Rouse Ball Professor of Mathematics at the University of Oxford. He is the author of The Emperor's New Mind, which was a New York Times bestseller and was awarded the UK's 1990 COPUS Prize for science writing. In 1988, he received the internationally prestigious Wolf Prize for physics, shared with Stephen Hawking, for their joint contribution to our understanding of the universe.

From Kirkus Reviews

A leading critic of artificial intelligence research returns to the attack, attempting to lay the groundwork for an analysis of the true nature of intelligence. Building on his arguments in The Emperor's New Mind (not reviewed), Penrose (Mathematics/Oxford) begins by refuting the assertion that true intelligence can be attained--or even adequately simulated--by the strictly computational means to which current computers are ultimately limited. Much of his argument depends closely on the application of G”del's Undecidability Theorem to Turing machines--deep waters for laypeople, although the fundamentals of his argument are accessible to readers without sophisticated mathematical training. Having disposed of the central tenets of current AI research, Penrose then turns to an even more fundamental question: the actual foundations in modern physics (i.e., relativity and quantum theory) of the phenomenon of consciousness. Here much of his summary depends on fairly complex mathematical reasoning, although the key points are summarized for the general reader who has been willing to follow him so far. Penrose feels that a new physical synthesis, reconciling the paradoxes of quantum theory and bringing them into harmony with Einstein's gravitational theories, is ultimately necessary to explain the noncomputational elements of consciousness and intelligence. He speculates on the possible role of cellular structures called microtubules in creating a quantum phenomenon on a macroscopic scale within the brain, but grants that more research is needed to establish any connection between physical and mental phenomena. His conclusion steps back to a philosophical overview of the subject, paying homage to Plato, among others. A challenging examination of a central problem of modern philosophy, with no final answers but plenty of food for thought.
