I made the mistake of reading some reviews of this book when midway through it. These reviews rightly pointed out that Harari's conclusions are not always based on particularly solid backgrounds, and that they can occasionally seem a little one-sided or shallow.
The positive of reading these reviews was that they helped me to read the rest of the book with a more critical eye. The downside was they stole some of the enjoyment and wonder that I experienced when first reading this book.
And this is a book which brings you wonder when you read it. The concept of 'modern myths' fascinated me, as did the interpretations of some elements of our modern life. Harari introduces big concepts and puts them into easy-to-understand terms. Perhaps too simplistic sometimes, which is where the criticism comes in!
Overall, I would describe this book as an excellent springboard into learning more about not just our history, but what it is that makes us human. You can use this book to identify topics which fascinate you, think about them in a new way and then maybe read other books to deepen or further your knowledge from there.
