An excellent examination of a fascinating subject. The Author takes a commendably even-handed approach without the slightest hint of bias. Nicely sourced with outstanding expository quotes and commentary. While the full study is not available for perusal the Abstract is. The Abstract alone though makes for interesting reading in and of itself and provides additional context and further elucidates the matter at hand for the reader. An indubitably worthwhile and, in fact, some might say, necessary read. Nicely done all around. Four stars!
