Once in a while along comes a book that forces us to rethink our world, gives us a startling new perspective on various issues of when, what, and why of our past, enhances our understanding of our current world, and stimulates well grounded speculation about our future. Sapiens: A Brief History of Humankind by Yuval Harari is such a book. No matter how busy we are in the day to day concerns of our life, Harari gives us a new insight into the full spectrum of human life, how it developed, why we came to be what we are, and what all this means for each of us. In a few passages Harari assumes, or an understanding of what he writes is at least benefited by, some familiarity with important books ranging from the Bible to the Koran, social phenomena as disparate as Buddhism and the Catholic Church, political movements ranging from liberalism to communism and the histories of China and the British Empire. In the pattern of books otherwise very different from each other such as the Book of Genesis and the novel Hawaii by James Michener, Harari begins with as close to the beginning as is practically possible. From the multiplicity of human forms that preceded and for a while coexisted with our species homo sapiens, he takes us through a tour reaching back to, and beginning with, the dawn of human existence to the opening of the future that is about to be among the possibilities of our fate. A point inherent in all this is how much that fate is up to our collective choices today. That he does so much in a book relatively short for the time covered and the range of ideas conicdred is a remarkable achievement.
