If you’re looking to give your brain a good workout, I heartily recommended Sapiens: A Brief History of Humankind by Yuval Noah Harari. The author does a superb job of bringing together the history of humanity from the early days of Hominids and demonstrating how and why we ended up where we’re at today and where we might be headed. It makes the reader want to investigate all the topics Harari raises in more details.
Its big picture approach stands out in contrast to the far too often narrow minded analysis of humanity’s problems and accomplishments we see in the news media. I gave it 5 stars in my review of Goodreads. com out of respect for its thoroughness and readability even though I don’t agree with a few of his conclusions. And there’s nothing brief about the book. There are parts I look forward to rereading (when I get my copy of the book back) because I would like to reflect further on his arguments. I found reading a couple of chapters at a time and then thinking about the content before reading more was the best way to approach the book.
