2,400 years ago there was a sudden and dramatic burst of new ideas across the world.

Simultaneously in Athens, Socrates was prompting his contemporaries to question their assumptions; in India, the Buddha was grappling with the boundary between the self and the world; and in China, Confucius was formulating a philosophy based on collective harmony. For all their differences, each was pioneering a provocative new way of thinking about ethics and politics, a shift from asking what the gods demand to asking how human beings should live together.

Was it simply a remarkable coincidence that these three figures appeared in the same lifetime, or might one set of ideas have influenced another? If these ideas did travel, they did so without scripture, conquest or divine revelation. These were not prophets, but teachers. They wrote nothing down. It was only through extraordinary followers and compelling arguments that their ideas might spread.

Time of the Sages tells the story of this watershed in the history of the human mind, and shows why these ancient questions about how to live still matter today.
