Machiavelli vs. the Classical Tradition
How Machiavelli broke from Plato, Aristotle, and Cicero by insisting on politics as it is, not as it should be.
The Great Break
Before Machiavelli, Western political philosophy was dominated by a tradition stretching from Plato through Aristotle to Cicero and then to Thomas Aquinas. Despite their differences, these thinkers shared a fundamental assumption: the purpose of politics is to make people good. For Plato, the just city was ruled by philosopher-kings who understood the Form of the Good. For Aristotle, the polis existed to cultivate human excellence — virtue — in its citizens. For Cicero, the Roman Republic was the practical embodiment of natural law. For Aquinas, political authority derived from divine law and was bound by moral constraints.
Machiavelli shattered this consensus. In Chapter 15 of The Prince, he wrote that he intended to pursue the 'effectual truth of the matter rather than the imagination of it,' because 'many have imagined republics and principalities that have never been seen or known to exist.' Anyone who ignores what people actually do in favor of what they ought to do 'learns his ruin rather than his preservation.' This single passage represents one of the sharpest breaks in the history of Western thought.
