Since most Freepers don't bother to read beyond article titles, it is likely that few actually know firsthand of Machiavelli's works at all. With that in mind, and in Machiavelli's defense:
In his Discourses on Livy are lessons on how the Roman Republic survived for 400+ years. Subsequent philosophers like Locke and Sidney were well aware of his research. They in turn were influential on America's Founding and Framing generations.
The Prince is well worth the time, and is pretty easy reading.
I recommend it to all.
The Discourses, on the other hand, are a little dated because of advances in military tech.
