@Learningpath: I second that. Professor Harari is a history professor but also an great researcher and visiting scholar, his writings add a solid different dimension to our thoughts. His writing brings a clear pictures of so many things. One thing I was amazed to learn his observation on how the Europeans came to the forefront of science and technology : That they started to believe what there are questions that never answered by their previous generations and that they have open field to explore, he gives an example of maps they used to draw until the point they know and keep test of it to further explore. Oh, I am still reading his other two books !!
