Clearly a very important work that should be preserved, regardless of whether one feels it caused good or bad changes. The entire Machiavelli family is very fascinating and their palace is a definite art work. It's almost a shame that you can't put the book inside the palace and then put -that- inside the time capsule. 

At any rate, a very well written paper, and it enlightened me on a subject that I had only a passing knowledge of prior to this. Your argument for The Prince is solidly built!
