"Penrose embarks on a sweeping survey of black holes, cosmology and thermodynamics in search of further support. The reader is treated to a tour of much of modern physics before being brought back to the central thesis: that minds must be taken seriously." Observer"A pedagogical tour de force, with some dazzling new ways of illuminating the central themes of science." Times Literary Supplement"Penrose takes us on perhaps the most engaging and creative tour of modern physics that has ever been written....the reader might feel privileged indeed to accompany Penrose on his magical mystery tour." Sunday Times"Will be universally cited by strong AI opponents as the definitive refutation of strong AI....An excellent introduction to the ideas which are involved in the strong AI hypothesis."
