It is time for a new view of human nature.
In summary, if you believe that humans are naturally selfish, this book isn’t going to change your mind - the evidence feels a bit cherry picked and not overly rigorous.
However, for someone that chooses to believe that people are naturally good, you’ll probably find this book really uplifting and encouraging (as I did).
It’s not too long, well written, and well worth a read - highly recommended.
