This is an interesting read, though there are places where it is obvious that the author is engaging in pure conjecture. He mostly points these places out, but not in all places. It is an interesting thesis, though it is not a new one.

The only reason is that I am giving it 4 stars instead of 5 is because of the scholarly shortcomings of the work. Apart from that, it is a worthwhile read with lots of great perspective and insight.
