I will not even comment on the material itself, other than to say that it is superb. However, the print quality is so poor as to merit only two stars. It is much worse than "newsprint," on roughly 20 pages of my copy, over a quarter of the page is virtually unreadable, the text is so light. The only reason this book merited two stars was its superb notes, illuminating some of the more perplexing aspects of the book. However, I would not recommend this particular copy unless found at a bookstore (sorry, Amazon) where the quality of the print can be evaluated.
