<P>This exciting book by three pioneers in the new field of cognitive science discusses important discoveries about how much babies and young children know and learn, and how much parents naturally teach them. It argues that evolution designed us both to teach and learn, and that the drive to learn is our most important instinct. It also reveals as fascinating insights about our adult capacities and how even young children -- as well as adults -- use some of the same methods that allow scientists to learn so much about the world. Filled with surprise at every turn, this vivid, lucid, and often funny book gives us a new view of the inner life of children and the mysteries of the mind. </P>
