I enjoyed the full book so much. Will read it again.

At time my work slows down and I take advantage to read books but I found that I don't usually finish long books. I guess it's the contest start and stop in longer books that really exhausted my enthusiasm. This summary book was a breeze to read and did it all in one sitting.

I have always been a bit skeptical of unauthorised summaries not because of any ethical debate but more so because of the quality. However I found this summary very well written and polished.

I'm happy with this purchase. Great book about human mankinds summary. Will read again.

Very poorly written from the standpoint of the English language. Any high school student could easily correct the mistakes, so “get some help, please.” Otherwise, it is too brief and the summary could be improved by more depth. In conclusion, the summary was helpful, though flawed, and I will now read the book.

I don’t think I have ever read anything so poorly written as this little summary of a masterpiece. The grammar, the syntax, the logic are all infantile. Read the real thing, not this insulting version.

Very enlightening history from a new perspective that really made me think about our place in the universe as humans. Very exciting read, would recommend to anyone who would like to be challenged!

Great book. I learned an extensive amount of human history and our unique advantages. The four week plan at the end of the book was also interesting and I'm going to incorporate some of the ideas to my business, especially around creating unquestioned ideologies or imagined worlds. I see it helping with my company culture.

The book left my mind in a blurr. I think it was so much information in one run through but I learned so much! I wish the author could also make an audible version so I can revisit the book on my morning commutes. I highly recommend it if you enjoy history, anthropology, psychology or just looking to challenge assumptions on our history!
