Humans, Jonsson explains, also possess an intuitive direction frame -- an internal compass -- that keeps these maps oriented (when it functions properly) and a dead-reckoning system that constantly updates our location on the map as we move through the world. Even the most cynical city-dweller will be amazed to learn how much of this innate sense we use every day as we travel across town or around the world.Both a scientific and a human story,Inner Navigationcontains a rich assortment of real-life insights and examples of the navigational challenges we all face, no matter where or how we live. It's a book that is as provocative to ponder as it is delightful to lose yourself in. Don't worry: Erik Jonsson will help you find your bearings.

Born in Sweden in 1922, Erik Jonsson grew up using the forest as his navigation school. He moved with his family to California in 1969. He lives in San Diego, California.
