Sam Harris speaks with Yuval Noah Harari about meditation, the need for stories, the power of technology to erase the boundary between fact and fiction, wealth inequality, the problem of finding meaning in a world without work, religion as a virtual reality game, the difference between pain and suffering, and other topics. Yuval Noah Harari has a PhD in history from Oxford University and is a professor in the Department of History at Hebrew University in Jerusalem. He specialized in World History, medieval history and military history, but his current research focuses on macro-historical questions: What is the relation between history and biology? What is the essential difference between Homo sapiens and other animals? Is there justice in history? Does history have a direction? Did people become happier as history unfolded? He is the author of two blockbuster books, Sapiens: A Brief History of Humankind and Homo Deus: A Brief History of Tomorrow.   Episodes that have been re-released as part of the Best of Making Sense series may have been edited for relevance since their original airing.
