Anyone who has studied even a smidgen of cultural anthropology would realize that Shlain's argument carries no weight. Where are all the pre-literate societies which practice goddess worship and treat women fairly? The fact is that the inequitable treatment of women is just as much if not even more prevalent in pre-literate societies as it is in literate ones.Shlain is exploiting the naive and undeserved attention which so many people offer for no other reason than that the author has before his name those magic letters "Dr". He should reserve that title for his working life. If his ideas had been forced to stand up under their own strength then the precious resources of paper and ink which were wasted on this book might have been saved for a better purpose.
