Published in 1948, hence the title of the book.
Btw spot on for broad generalizations of a group based on a few that take a name(often not based on actual beliefs/actions). All sides do this.
I stand corrected...don't know why I thought it was the 50's but I did. The book means much more when you are 50 yrs old than when you are 13 and is a homework assignment.
