Teacher looking for articles defining, evaluating, or diagnosing the concept of propaganda

[mythyc]

hi everybody,
I a college English instructor who teaches Senior composition and I'm redesigning my class around Plato's "Allegory of the Cave". I want to build a unit on propaganda definition and debunking and am posting to ask if any of you could recommend a good essay or two on this. I am already using Neil Postman's "Propaganda", a good short piece (you can find it here, as a PDF: http://neilpostman.org/articles/etc_36-2-postman.pdf ), but would like more variety and depth. If you could recommend anything that would be great. For the students' essays, I plan to have some of them visit this forum to see how propaganda debunking works, and if you could recommend other pages like this one so I could give them more options, I would be greatly appreciative. thanks for your consideration,
mythyc
