After reading these posts, I checked my books, I have 2 M. Grant books and time and money permitting will add more.
The importance of knowledge of past history brought to mind the following movie.
The Stranger (1946) with Orson Welles, Loretta Young and Edward G. Robinson, which takes place in a small New England college town.
One line from that movie refers applying the solution the Carthaginian solution by Rome to the Germans after WW2 by Orson Wells' character. The movie did explain some of the implications, but also assumed some knowledge of ancient history. This is a chilling movie.
