Why does life in society make us so unhappy? Why has civilization always been marked with social unrest? From the time of Plato, our greatest thinkers have understood that in order to confront the ills of the city, one must first look to the individual, to the maladies and discontents of the human soul. In this novel reading of Plato's Republic, the insights of Nietzsche and Freud are brought to bear on one of western civilization's most important texts. But what is at stake is far more than our interpretation of the Republic. City of Man will leave readers better equipped to face the crises that confront us today by reintroducing the import of that oft-quoted but rarely practiced Delphic maxim: know thyself.
