First there is great clarity in the author’s work. In essence it was very well written. As with most well written history it is a page turner.
I think Harari took too broad an approach in too short a period of time in his book. He particularly lacked an appreciation of what it took to argue the non-material/ spiritual perspective vs. the material/atheistic point of view, which, is his own. He just made blanket statements that were not reasonably sourced in combating the theistic view. I believe it is the greatest shortcoming in the book.
As I understand their work both Hugh Ross, a Cal Tech trained scientist, and NT Wright, a highly lauded Christian author see the spiritual Kingdom of God as present in another dimension. I am not sure the author has any idea of that feasible interface between ours and a spiritual dimension. No less a scientist than Francis Collins, MD, Director of the American National Institutes of Health has authored a work on his strong Christian beliefs. He also headed the Human Genome Project that Harari actually mentioned in his work.
To my knowledge Yuval Harari has neither scientific nor theological degrees. I believe that his lack of appreciation in those areas left his argumentation short of the mark. It actually gave me pause to ask myself in his” inorganic life” chapter IF he truly understood the cutting edge technology he described, particularly where it might be flawed, which he excluded.
Harari mentioned Paul, who wrote most of the New Testament, but failed to mention his key love chapter where he says, “I shall know even as I am also known.” which, as I pointed out in “Look Backward Angel,” suggests a journey to gain self-knowledge as a part of the Christian/Messianic Jewish journey. Harari saw self knowledge, as I understood him, as a key to happiness, which makes his failure to recognize what I have quoted as, to me, an unfair diminution of the beauty and value of the Christian/Messianic Jewish life.
On the other hand it was enjoyable to appreciate the broad expanse of human history which I had never seen in one book. He raised some interesting elements of that history and raised some fascinating questions about it..
