I often ponder why Carl Sagan never added another book to his famous reading list for students, as it makes a fairly reasonable argument that most populist movements are essentially interchangeable =3
"The True Believer: Thoughts on the Nature of Mass Movements" (Eric Hoffer, 1951)
https://www.amazon.com/True-Believer-Thoughts-Nature-Movemen...
This should be at the top of everyone's reading list. It was the blueprint for the CIA's regime change agenda, led too MKUltra/Mockingbird and is still required reading for most Terrorism studies classes.
I don't think this list is as famous as you assume it to be. The only "Carl Sagan reading list" I managed to find [0] is apparently his personal TODO note (books he plans to read, but haven't at the moment of writing). Which obviously isn't the same thing as "his famous reading list for students".
