This concept of this book is much better than the execution. There are obvious typos throughout - including in the quoted text. I checked the original and verified that mistake was made by this book and not the original author.
Additionally, I was disappointed by 'opposing' views. One chapter uses individuals from the same institute. Oftentimes, the commenters are like ships passing in the night. They are talking about completely different things. There's no conflict between the two essays.
