"In 1993, Norwegian explorer Erling Kagge spent fifty days walking solo across Antarctica, becoming the first person to reach the South Pole alone, accompanied only by a radio whose batteries he had removed before setting out. In this book, ... Kagge explores ... silence ... By recounting his own experience and discussing the observations of poets, artists, and explorers, Kagge shows [readers] why silence is essential to ... sanity and happiness--and how it can open doors to wonder and gratitude"--Jacket flap.
