This work by Niccolo Machiavelli was written in the 16th century and has definitely stood the test of time as an observation on princes (or CEOs or managers or anyone else in charge) and their subjects (or employees or students or anyone else not in charge). Some of his conclusions may rankle modern ethics or mores, but demand a well-formed response rather than an outright dismissal, for his commentaries regard the very nature of man, regardless of man's historical context.
Below is a table with links to each chapter of The Prince, with commentary following each chapter. If you wish to add to a commentary on a chapter, please send it in an email to me. (My address is at the bottom of each page.) The table below will be available at the bottom of each chapter, allowing for ease of navigation.
