I was hopeful that this would allow me to get the benefit of many non-fiction books without having to read the full texts. Unfortunately, the necessary lack of supporting detail in evidence and reasoning renders all arguments as empty assertions. One cannot interrogate the validity of the idea or understand the path to the conclusions without the detail of the book, so one is left merely to judge them all against one's pre-existing model. Nuance and tone are obliterated. Read the books!
