Axial Age and Its Consequences [EPUB ebook] 

This book makes the bold claim that intellectual sophistication was born worldwide during the middle centuries of the first millennium bce. From Axial Age thinkers we inherited a sense of the world as a place not just to experience but to investigate, envision, and alter. A variety of utopian visions emerged and led to both reform and repression.
