For the last couple of years, I haven't eaten beef or pork. Part of this was dietary but the larger portion was due to my distaste with the way these animals are dealt with in the food industry. After reading Sapiens: A Brief History of Humankind I have decided to stop eating all meats for good. I'd be quite surprised if others reading this book didn't feel the same way. (This will make sense later.) This book covers exactly what the title says. Yuval Noah Harari touches on almost every aspect of what it means to be human. I can see why this book could be contentious in some circles as he is of the belief that consumerism, imperialism, and communism are religions instead of merely ideologies. He has a no holds barred attitude about the way in which humans have ravaged the planet and taken advantage of others of our species as well as flora and fauna. (Remember the no eating chicken thing?) What was most intriguing about Sapiens were the questions that he raised about the nature of happiness. There have been many books about how to be happy but no research into how happiness is measured and its trends throughout the years. (Maybe he has an upcoming novel in the works.) If you're interested in culture, human evolution, and a unique perspective of the world then you're likely to enjoy this book. I will say that a lot of this was common knowledge and/or already known to me as an Anthropology major. The second half of the book is where it got really interesting. I love a good thought experiment and trying to figure out answers to seemingly unsolvable problems is my idea of a good time. :-) I'd give this book a solid 8/10.
