'I encourage all of us, whatever our beliefs, to question the basic narratives of our world, to connect past developments with present concerns, and not to be afraid of controversial issues.' Dr Yuval Noah Harari has a PhD in History from the University of Oxford and now lectures at the Hebrew University of Jerusalem, specialising in World History. His research focuses on broad questions, such as: What is the relation between history and biology? Is there justice in history? Did people become happier as history unfolded? 65,000 people have signed up to his online course, A Brief History of Humankind. Sapiens is an international bestseller and is being published in more than 20 languages… worldwide. In 2012 Harari was awarded the annual Polonsky Prize for Creativity and Originality in the Humanistic Disciplines.
