My rating is meaningless because I did not read the book, at least not after the first two or three chapters; I clicked three stars in order to be able to post a review because I think it’s important people know what this book is and is not. I totally misunderstood what it was about. I thought it was literally about what is indicated by the title: people trying to find heaven on earth, i.e. a utopia here, the best place to live, a society where virtually everyone is happy, healthy, satisfied with life, possibly the latest life-extending medical and technical breakthrough to help us reach immortality here on earth. Instead, it’s a philosophical/religious tract exploring what individuals and societies believe about heaven and hell or some other form of afterlife, and why they do or don’t. The topic really is death. Once I realized that’s all it was going be, I stopped reading.
