Daniel C. Dennet's description of this scientist's travelogue: "How did the mind evolve? It takes a scientist of extraordinary breadth who is also a master storyteller to sketch the boundaries of this mega-narrative, and William Calvin has once again given us a feast of new perspectives, enriching the vision of our future as much as our past." "As delightful as it is thought-provoking." -- The Los Angeles Times Used Book in Good Condition
