The holy grail of scientists and psychologists since the beginning of artificial intelligence has been to replicate thought patterns of the human mind. Challenging the notion that this can ever be achieved through state-of-the-art research, legendary AI authority David Gelerntera "rock star" (New York Times) of the computing worldsurprisingly turns to literature, hoping that the works of introspective geniuses like Shakespeare, J. M. Coetzee, and Karen Blixen can help answer the same fundamental questions that neuroscientists have been struggling with for generations. Indeed, Gelernters landmark "spectrum of consciousness" decodes some of the deepest, most mysterious aspects of the human mind, such as the numinous light of early childhood, why sadism and masochism underpin some of our greatest artistic achievements, and why dreams often do predict the future. With "penetrating insight and a graceful, inviting presentation" (National Review), The Tides of Mind revolutionizes our very understanding of what it means to be a human being.
