I read the book quite quickly in order to gain some idea of the shape of it and its manner of presentation.
The book is an academic text more suited to study rather than general reading. It seems a little haphazardly structured and is peppered with typographical errors.
Nonetheless there is a great deal of interesting information. I shall return to this book at some point and approach it in a slower more studious manner.
An amazing book, but not an easy read. It will take years of study to fully take in its content. Its content is beyond compare, but the style of presentation could have made it more accessible.
2024 update: I have made a detailed study of this book now and continue to regard it as wonderful, but not easy to read. Highly recommended as a study book, but not so much as an inspirational read.
