It is popular because the author was very much part of popular culture before he saw the problem with western philosophy, so he was able to write well to his audience. But this doesn't mean that his audience is capable of understanding the message, and based on the reviews I read on Amazon, none of the readers get it. The book is ultimately a critique of Plato's view of universal truth, and a discussion of some of the ill effects that Plato's view caused.
This book is actually very closely related to
The Philosophy of Hebrew Scripture. This is because the pre-Plato Athenian view of truth is basically the same as the Old Testament view of truth.
