Thought provoking. Amazing way of raising controversial and disturbing questions by providing indeniable and well researched historic as well as contemporary proof points. Must read the Sapiens book before reading this one in order to understand the thought process. It expanded and enriched my views of my own life and the world. It has also created a healthy confusion in my mind about our existence and behavior. I intend to work upon it to gain clarity and modify my existence for better.
