One of the great minds of the 20th century explores the duality of human nature in all its variations in cultures around the world. Fascinated by the polarity of being, Paz has boldly attempted to write a |history of man|. Unlike countless other histories that simply chronicle civilizations and cultures, Paz's work explores the human heart, the meaning of human nature and the duality that exists within all beings and, it would seem, all things. Ranging across cultures and centuries, Paz explores opposites and contradiction through the ages.
