This revolutionary book offers fresh answers to longstanding questions of human origins and consciousness. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon leads us on a carefully grounded neurobiological expedition into a view of mind that does not reduce to soulless, clockwork mechanism, but is instead an emergent feature of a universe that is "nascent heart and mind." His book not only provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.
